Detailed Description
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings. What has been described herein is merely a preferred embodiment in accordance with the present invention and other ways of practicing the invention will occur to those skilled in the art and are within the scope of the invention.
The disclosed cable laying apparatus 100 enables cable transportation and laying work to be performed using mechanical means, as shown in fig. 1, reducing labor costs during the period, while also reducing cable damage that occurs when manually hauling cables. In addition, the cable laying device 100 disclosed by the invention can adapt to the laying environments of different electric equipment, so that the cable laying efficiency is improved. Specifically, in fig. 1, the cable laying device is capable of laying the cable at a certain height at a certain angle and length to a position most convenient for the electric equipment by means of mechanical driving.
As can be seen with reference to fig. 1 and 2, the cable laying device 100 comprises a cable laying section with a reference section 11 and an adjustable length extension 12, a turnover mechanism 20 and a positioning adjustment mechanism 30. In particular, the reference section 11 and the extension section 12 are connected at the longitudinal ends so as to be able to rotate relative to one another and so as to be able to accommodate and transport the laid cables. In particular, the elongate section can be provided at one longitudinal end or at both longitudinal ends of the reference section, as required. In this case, the extension 12 can be extended from the reference section 11 in a targeted manner depending on the operating environment of the consumer. In order to further achieve flexibility in use of the cable laying device 100, the cable laying device 100 further includes a positioning adjustment mechanism 30, wherein the positioning adjustment mechanism 30 includes a rotation component 31, which can be connected to the reference section 11, for example, at one longitudinal end or at a certain longitudinal position of the reference section 11, so that the reference section 11 or the cable laying portion can be rotated by the rotation component, thereby adapting to different installation positions of the electric equipment. The cable laying device 100 comprises a turnover mechanism 20, wherein the turnover mechanism 20 is connected with the reference section 11 and the extension section 12, so that the extension section 12 can be driven to turn over at different angles from the reference section 11 according to use requirements, different heights and different lengths of the whole cable laying part are realized, and different cable laying possibilities can be presented.
Here, it should be noted that, in the present invention, the "longitudinal position" of the reference segment 11 refers to a position in the longitudinal direction of the reference segment 11 or the elongated segment 12.
Optionally, in order to enable the cable laying device 100 to better adapt to electrical equipment of different heights for cable laying, the positioning adjustment mechanism 30 may further have a lifting unit 32 for adjusting the height of the cable laying section. In order to avoid interference with the rotational movement of the cable assembly at the same time, the rotary assembly 31 can be arranged on the lifting unit 32 and the lifting unit 32 can be connected to the cable assembly or the reference section 11 via the rotary assembly 31. In this case, the rotating assembly 31 can rotate the reference section or the cable laying section around the lifting unit 32.
In particular, the rotary assembly 31 may alternatively be designed as a gear assembly known from the prior art, wherein the gear assembly may be driven by an external motor or other drive mechanism, and the output thereof may be connected to the reference segment 11 and bring the reference segment 11 into a rotary motion.
Alternatively, as shown in FIG. 3, canting mechanism 20, which carries elongate section 12 in a canting motion, may include a canting drive 21 and a linkage assembly 22 driven thereby. Specifically, the link transmission assembly 22 includes a first link member 221 and a second link member 222, wherein one end of the first link member 221 is connected with the reference section 11, and the other end is pivotally connected with the second link member 222, while the other end of the second link member 222 is connected with the extension section 12, and the reference section and the extension section are connected by a pivot shaft 13, so that the first link member 221, the second link member 222, the reference section 11 and the extension section 12 can form a four-bar linkage. In this case, the tumble drive section 21 is connected to and drives the pivot shaft between the first link member 221 and the second link member 222 to perform a linear reciprocating motion, so that the second link member 222 drives the extension 12 to perform a tumbling motion.
Alternatively, the tilting drive 21 can also be connected to and carry the first link element 221 connected to the reference section 11 into a rotary reciprocating movement, so that the second link element 222 carries the extension section 12 into a tilting movement.
Within the scope of the present invention, the tumble drive section 21 may alternatively be configured to include a tumble drive hydraulic cylinder, wherein the piston 211 of the tumble drive hydraulic cylinder may be connected with the link turning assembly, i.e. the pivot shaft between the first link member 221 and the second link member 222 or the first link member 221, to thereby effect the drive of the link transmission assembly 22.
In the context of the present invention, in order to achieve a tilting movement with greater stability and balance, the tilting mechanism 20 can be arranged in the longitudinal direction of the pivot axis 13 between the reference section 11 and the extension section 12, for example in pairs at its longitudinal ends.
Since the cable laying device 100 is in operation, the cable laying section is often present at a certain height in the form of an elongated load carrier, in order to maintain the height of the elongated cable laying section, the disclosed cable laying device 100 may optionally further comprise a height retaining mechanism 40, which height retaining mechanism 40 may be provided jointly with the lifting unit 32 of the positioning adjustment mechanism 30 and maintain the desired height of the cable laying section. Specifically, the height holding mechanism 40 may have one end connected to the positioning adjustment mechanism 30 and the other end connected to the reference segment 11, specifically, connected to a longitudinal position of the reference segment 11 outside the installation positioning adjustment mechanism 30 or the rotating assembly 31, and support and hold the height of the cable laying part. That is, the height keeping mechanism 40 may exist in a direction inclined with respect to the longitudinal direction of the cable laying part.
In this case, alternatively, the positioning adjustment mechanism 30 may be provided at one longitudinal end of the cable laying section or the reference segment 11. While the height holding mechanism 40 can support the cable laying section at another longitudinal position of the reference segment 11, thereby improving the stability of the cable laying section. For example, it is conceivable that the height maintaining mechanism 40 comprises a hydraulic cylinder, in which a piston is connected to the reference section 11 and supports the cable laying section by a telescopic movement.
To facilitate transport of cable laying apparatus 100, it may also include a carrier mechanism 50. In this case, it is conceivable that the support means 50 comprise a semi-trailer, a vehicle-mounted structure or a skid, while the positioning adjustment means 30 can be fixedly placed on a chassis 51 of the semi-trailer, the vehicle-mounted structure or the skid.
In the case of the presence of the support means 50 or of the semitrailer, truck-mounted structure or skid mounting, when the cable laying section is rotated through an angle of 90 degrees or more relative to the support means 50, it is likely that the center of gravity of the entire cable laying device 100 will shift away from the support means 50 and towards the cable laying section. Thus, in order to also stably hold the carrier mechanism 50 in the above working condition, the cable laying device 100 may optionally comprise a lifting leg assembly 60 for stabilizing the carrier mechanism 50, which comprises at least one lifting leg 61 supporting the stable carrier mechanism 50 by a lifting movement or a telescoping movement. The lifting legs can be attached at both lateral sides of a semitrailer, truck structure or skid-mounted chassis 51 (as shown in fig. 1 or 2). Depending on the degree of rotation of the cable laying section relative to the chassis 51, the lifting legs are configured to be rotatable by different angles relative to the chassis 51, so that an optimum support stability of the support means 50 is achieved.
Furthermore, within the scope of the invention, the direction of connection between the elongate section 12 and the reference section 11 is not limited. That is, at the longitudinal ends of the elongate section 12 and the reference section 11, the elongate section 12 may comprise an elongate section attached to the longitudinally extending surface of the reference section 11 or an elongate section attached at the lateral side of the reference section 11. In other words, when the extension 12 is connected to the longitudinally extending surface of the reference segment 11, the extension 12 can lie on the reference segment 11 without being "stretched" or "flipped", whereas when the extension 12 is connected to both lateral sides of the reference segment 11, the extension 12 can rest against the lateral sides of the reference segment 11 without being "stretched" or "flipped".
According to the cable laying device disclosed by the invention, the cables of a plurality of electric equipment can be conveniently and efficiently supplied with power. As shown in fig. 1, depending on the location and site limitations of the consumer, the cable laying device can have its cable laying section or reference section together with the extension section rotated by a certain angle (e.g. 90 degrees in fig. 1) by means of the rotating assembly, and the height of the cable laying section is adjusted by means of the lifting unit, so that the rotational position and height of the cable laying section are more suitable for connecting the consumer. Meanwhile, according to the number of the electric equipment and the height of the connecting piece of the electric equipment, the extension section of the cable laying part can be correspondingly turned over for a certain angle from the reference section, and a certain inclination is formed to supply power to the electric equipment through cables. Therefore, the cable laying device disclosed by the invention not only can efficiently lay the cable, but also can reduce the abrasion of the cable by bearing the protection cable through the cable laying part.
The foregoing description of various embodiments of the invention is provided for the purpose of illustration to one of ordinary skill in the relevant art. It is not intended that the invention be limited to a single disclosed embodiment. As above, many alternatives and modifications of the present invention will be apparent to those of ordinary skill in the art in light of the above teachings. Thus, while some alternative embodiments are specifically described, other embodiments will be apparent to, or relatively easily developed by, those of ordinary skill in the art. The present invention is intended to embrace all such alternatives, modifications and variances of the present invention described herein, as well as other embodiments that fall within the spirit and scope of the present invention as described above.
