The application will be described in detail below with reference to the drawings in connection with exemplary embodiments.

Example 1

Referring to fig. 1, 2 and 3, the present embodiment provides a rope winding structure suitable for an electric pole, hereinafter referred to as a rope winding structure.

In this embodiment, the roping arrangement includes a mounting base 100 and a lifting module 200, the mounting base 100 being adapted to be placed on a tamped foundation. Wherein, be equipped with the pole body 300 on the mounting base 100, the pole body 300 includes tower body assembly pulley 310, dolly assembly pulley 321, lifting hook assembly pulley 331 and jib loading boom 340.

The lifting module 200 comprises a lifting mechanism 210, a first pulley 220, a second pulley 230 and a lifting steel wire rope 240, wherein the lifting mechanism 210 is arranged on the mounting base 100 and is positioned at one side of the holding pole main body 300; in the vertical direction, the first pulley 220 is located below the turret block 310, and the second pulley 230 is located below the first pulley 220; one end of the lifting wire rope 240 is wound on the winding drum 211 of the lifting mechanism 210, and the other end sequentially passes through the first pulley 220, the second pulley 230, the tower pulley block 310, the trolley pulley block 321 and the lifting hook pulley block 331 and is connected with the arm tip of the lifting arm 340.

The first pulley 220 may move back and forth along the direction of the spool axis (which may be understood as the center line of the spool 211 when rotating), so that the deflection angle of the hoisting wire rope 240 on the spool 211 is less than or equal to the preset standard value. Alternatively, the preset standard value may be 1.5 °.

Further, an included angle formed between the direction of the central line from the inner edge of the spool 211 at any end in the spool axis direction to the first pulley 220 and the first vertical plane perpendicular to the spool axis is smaller than or equal to a preset standard value. In this way, it is ensured that the maximum deflection angle of the hoisting wire 240 on the spool 211 is also less than or equal to the preset standard value.

It can be appreciated that, in the rope winding structure provided in this embodiment, the lifting mechanism 210 is integrated on the mounting base 100 of the mounting pole body 300, the first pulley 220 and the second pulley 230 are arranged on the pole body 300 along the vertical direction, the second pulley 230 is located below the first pulley 220, the first pulley 220 is located below the tower pulley block 310, one end of the lifting wire rope 240 is wound on the winding drum 211 of the lifting mechanism 210, and the other end sequentially passes around the first pulley 220, the second pulley 230, the tower pulley block 310, the trolley pulley block 321 and the hook pulley block 331 and is connected with the lifting arm 340 to form a closed loop. In order to better integrate the lifting mechanism 210 on the mounting base 100, the first pulley 220 is configured to move back and forth along the axis direction of the drum, so that when the lifting steel wire rope 240 on the drum 211 is in rope arrangement, the first pulley 220 is adapted by moving back and forth along the axis direction of the drum, so that the deflection angle of the lifting steel wire rope 240 on the drum 211 is smaller than or equal to a preset standard value, and the lifting mechanism 210 can normally unwind and retract the rope.

Referring to fig. 4, the letter C in fig. 4 is the deflection angle of the hoisting rope 240 on the reel 211. It should be noted that, the maximum deflection angle of the lifting wire rope 240 on the spool 211, that is, the included angle formed between the direction of the central connecting line from the inner edge of any end of the spool 211 in the spool axis direction to the first pulley 220 and the first vertical plane perpendicular to the spool 211 axis. The hoisting wire rope 240 on the winding drum 211 is generally wound with multiple layers, and each layer of the hoisting wire rope 240 is provided with a plurality of loops, and the loops are uniformly arranged along the axial direction of the winding drum 211. If the deflection angle is too large, the lifting steel wire rope 240 is wound back onto the winding drum 211 too early, gaps are generated between the rope loops close to the edge of the winding drum 211, and the pressure on the contact points of the lifting steel wire rope 240 is increased, so that the lifting steel wire ropes 240 are mutually extruded, interference and damage are easy to occur, and the service life of the lifting steel wire rope 240 is influenced.

Referring to fig. 1 to 4, compared with the prior art, the rope winding structure suitable for the electric pole according to the present embodiment integrates the lifting mechanism 210 and the pole body 300 on the mounting base 100, and can ensure normal rope discharging and rope collecting of the lifting steel wire, thereby shortening the arrangement length of the lifting steel wire rope 240, and simultaneously eliminating the need to separately dig a ground anchor pit and fix a preset ground anchor for the lifting mechanism 210, thereby greatly reducing the construction difficulty and the construction cost.

In order to more clearly describe the technical solution of the present application, the following description will be given of the roping arrangement provided in this embodiment. The method comprises the following steps:

referring to fig. 2,3 and 5, in the present embodiment, the first pulley 220 is located at a side of the second pulley 230 near the spool 211.

Alternatively, the hoisting wire 240 remains piled up on the rope entry side and the rope exit side of the first pulley 220. This ensures that the first pulley 220 is forced downward as much as possible.

Optionally, the first pulley 220, the second pulley 230, and the spool 211 lie in the same second vertical plane, wherein the second vertical plane is parallel or coincident with the first vertical plane. Of course, in some embodiments, there may be a certain misalignment between the first pulley 220 and the second pulley 230, where the misalignment ensures that the deflection angle of the looped-around lifting wire 240 between a pulley and the second pulley 230 meets design requirements.

The first pulley 220 may be mounted on a mounting platform 351 on the climbing frame 350 of the pole body 300, so as to ensure that the first pulley 220 has a sufficient mounting height, thereby ensuring that the deflection angle of the lifting wire rope 240 on the winding drum 211 meets the design requirement. Of course, in some embodiments, a mounting bracket (not shown) may also be provided at a predetermined height of the climbing frame 350, through which the first pulley 220 is mounted.

Specifically, the first pulley 220 includes a first wheel seat 221, a first wheel axle 222, and a swing pulley 223; first wheel mount 221 is disposed on mounting platform 351 of climbing frame 350 of pole body 300; the first wheel axle 222 is disposed on the first wheel seat 221; the axle hole of the swinging pulley 223 is provided with a bearing 224, and the bearing 224 is sleeved on the first axle 222 and is in clearance fit with the first axle 222. In this way, the swing pulley 223 can move back and forth along the axial direction of the first axle 222 with the reeling and unreeling of the reel 211, and the swing pulley 223 can also rotate relative to the first axle 222.

Optionally, the maximum travel of the oscillating pulley 223 oscillating on the first axle 222 is less than or equal to the roping width of the spool 211. In this way, the deflection angle of the lifting steel wire rope 240 from the winding drum 211 to the swinging pulley 223 is ensured to meet the rope discharging and receiving requirements of the steel wire rope on the winding drum 211.

Further, the first wheel seat 221 includes two first ear seats arranged in alignment, and the distance between the two first ear seats is the maximum stroke of the swing pulley 223 swinging on the first wheel axle 222.

The fixed pulley 233 is rotatably disposed on the second axle 232. The second wheel seat 231 includes two second ear seats arranged in alignment, and the second pulley 230 is different from the first pulley 220 in that the fixed pulley 233 in the second pulley 230 only rotates relative to the second wheel axle 232, and a second rope blocking rod 234 is disposed on a side of the second wheel seat 231 facing away from the pole body 300.

Referring to fig. 7, optionally, the lifting mechanism 210 further includes a motor 212, and the motor 212 is in transmission connection with the roller 211; the motor 212 and the winding drum 211 are located on the same straight line, so that a linear lifting mechanism is formed, the size of the linear lifting mechanism is relatively smaller, and the radial installation size of the winding drum 211 can be effectively reduced, so that the lifting mechanism 210 is conveniently integrated on the installation base 100.

Referring to fig. 1, fig. 2 and fig. 3, further, the present embodiment also provides an electric pole, including the rope winding structure provided by the above embodiment.

In this embodiment, the power pole is a floor-standing double-flat-arm power pole. Thus, two sets of same rope winding structures are arranged on the electric pole, and the two sets of rope winding structures are mirror images respectively and share one pole body 300. It will be appreciated that two lifting mechanisms 210 are integrated into mounting base 100, with two lifting mechanisms 210 being located on either side of pole body 300.

Example two

Referring to fig. 1 and 2, the present embodiment provides an electric pole. This embodiment is an improvement on the technical basis of the first embodiment described above, and differs from the above embodiment in that:

Referring to fig. 7, 8 and 9, the mounting base 100 includes a mounting base 120 and a plurality of base plates 110. The plurality of base plates 110 are spliced in turn along the width direction thereof to form a bearing base surface 110a, and the bearing base surface 110a is used for mounting the pole body 300 of the electric pole. Referring to fig. 8, a direction indicated by a letter W is a width direction of the base plate 110, and a direction indicated by a letter L is a length direction of the base plate 110.

Referring to fig. 10, two adjacent base plates 110 are engaged with each other in a snap-fit manner. In order to more clearly describe the technical solution of the present application, two adjacent base boards 110 are defined as a first base board 110b and a second base board 110c. The first base plate 110b is provided with a first fastener 111 on a side close to the second base plate 110c, and the second base plate 110c is provided with a second fastener 112 on a side close to the first base plate 110 b. When the first base plate 110b and the second base plate 110c need to be spliced, the first fastener 111 on the first base plate 110b is aligned with the second fastener 112 on the second base plate 110c to be fastened.

Optionally, the first fastening component 111 and the second fastening component 112 may be in a male-female fastening structure. When the first fastener 111 is designed as a male fastener, the second fastener 112 is designed as a female fastener; when the first fastening member 111 is designed as a female fastening member, the second fastening member 112 is designed as a male fastening member.

In order to ensure the stability after the first and second base plates 110b and 110c are spliced, a plurality of first fastening members 111 and corresponding second fastening members 112 may be disposed at intervals along the longitudinal direction of the base plate 110.

When the number of the base plates 110 is three or more, the first fastening members 111 or the second fastening members 112 are provided on both side surfaces of the base plate 110 sandwiched therebetween in the width direction of the base plate 110.

Of course, in some embodiments, the opposite sides of the base plate 110 on both sides may not be provided with the first fastening members 111 and the second fastening members 112 along the width direction of the base plate 110.

It can be appreciated that after the two adjacent base plates 110 are spliced, a gap is formed at the splice, and the existence of the gap can make the base plates 110 shake to some extent, resulting in unstable splicing. Thus, in order to solve the problem that the shaking between the two base plates 110 is stable and improve the stability of the splicing, the mounting base 100 applicable to the electric pole according to the embodiment further includes the wedge-shaped push block 130.

Wherein, each two adjacent foundation slabs 110 are provided with a wedge-shaped push block 130 therebetween, and the wedge-shaped push block 130 is used for being abutted against the side surfaces of the two adjacent foundation slabs 110. In this way, the wedge-shaped push blocks 130 are used for extruding the side surfaces of the two adjacent foundation plates 110, so that the foundation plates 110 are ensured to be more stable after being spliced. It will be appreciated that the wedge pushers 130 may be inserted into the gaps between two adjacent base plates 110 by external force.

Further, along the width direction of the base plate 110, the base plates 110 on two sides are provided with mounting seats 120, so as to be suitable for the electric pole of the floor type double-flat-arm structure.

The mounting base 120 includes four third ear bases 121, and the four third ear bases 121 are distributed on the corresponding base plate 110 and are welded with the base plate 110. The four third ear seats 121 are connected with the lifting mechanism 210 through pin shafts.

Referring to fig. 2, 7 and 8, in the present embodiment, a mounting chassis 140 for mounting a pole body 300 is provided on the bearing base 110 a. The mounting chassis 140 comprises two cross-arranged support beams 141. Wherein the support beam 141 obliquely spans each base plate 110 and is connected with each base plate 110 by bolting or welding.

Further, the mounting chassis 140 further includes two fixing beams 142, where the two fixing beams 142 are distributed along the length direction of the base, and are located at two ends of the two supporting beams 141. The fixed beams 142 are distributed and connected with the two support beams 141, so that a stable triangle structure is formed between the fixed beams 142 and the two support beams 141.

Compared with the prior art, the mounting base 100 provided in this embodiment is spliced into a whole through a plurality of base plates 110, so as to form a bearing base surface 110a, and the pole body 300 of the electric pole can be mounted on the bearing base surface 110 a. And along the width direction of the base plates 110, the mounting seats 120 are arranged on at least one base plate 110 positioned on two sides of the plurality of base plates 110, and the lifting mechanism 210 of the electric pole is mounted through the mounting seats 120, so that the lifting mechanism 210 avoids the pole body 300. Thus, the mounting base 100 suitable for an electric pole according to this embodiment can integrate the pole body 300 and the lifting mechanism 210, so that the lifting mechanism 210 does not need to be mounted at a position far away from the electric pole, is not limited by construction sites, saves the working procedures of digging a ground anchor pit on site and presetting the ground anchor for fixing the lifting mechanism 210, is more convenient to mount, shortens the required steel wire rope, and greatly reduces construction cost.
