Abstract
The utility model relates to a tool of a pull rope, in particular to a rope drawer used in drawing a steel wire rope through a tackle block. The utility model is characterized in that one end of an expansion and contraction net is provided with a connecting ring, the other end is an opening, and a metal fastening ring is sheathed on the transition spot of the connecting ring and the expansion and contraction net, then a rectangular connector is pressed on a node of the opening of the expansion and contraction net, further the expansion and contraction net is capable of being an elastic metal net with diamond-shaped or square shaped holes which is cross braided by a steel rope, and the expansion and contraction net is also capable of being a net which is cross braided by a nylon rope or a chemical fiber rope. Using the rope drawer, the steel wire rope is conveniently pulled by the rope drawer through a narrow space; further the utility model has the advantages of good installation guidance, safe and reliable use, improved work efficiency without any slippery falling.
Description
The utility model is a kind of instrument of tow rope class, wears the threading device of using when the sheave block especially for wire rope.
Steel cable at the lifting appliance oil-well rig is installed, the installation of cable stayed bridge steel cable, electric transmission line sets up, underground cable is laid, and in the underground installation of part such as steel pipe, owing to need the rope class pass narrow space, both dangerous as directly penetrating with current practice, and the end head easily bend make the rope inconvenience pass pulley, labor intensity is big, inefficiency.
The purpose of this utility model is, a kind of threading device is provided, it very easily haulage cable pass narrow space, make that guidance quality is installed is good, landing can not appear, safe and reliable, increase work efficiency.
The technical solution of the utility model is: design a kind of threading device, it is characterized in that: its breathing net one end is a connecting ring, and the other end is an opening, and connecting ring and breathing net transition position are with the metal retaining ring.
Be pressed with rectangle joint on the node of described breathing net opening.
The rhombus that described breathing net can be the steel cable interlacing or the elastic metallic net of square opening.
Described breathing net can be the net of nylon rope or chemical fiber rope interlacing.
The transition position of described connecting ring, retaining ring, breathing net can be with plastic sheath or nylon sheath wire.
Can be with metal peach shape ring in the described connecting ring.
Characteristics of the present utility model are: use threading device to compare with existing operating method, have safe and reliablely, landing can not occur, guidance quality good (stuck phenomenon can not occur) labor intensity is low, characteristics such as working efficiency height.
Threading device utilizes quadrilateral unstability principle design, and the threading device circle bag shape account net that contracts can be out of shape when stressed, takes off effect tight or that unclamp rope class part thereby reach it, realizes the purpose of tow rope class part.
Below in conjunction with embodiment's accompanying drawing the utility model is described further.
Accompanying drawing 1 is the example structure schematic representation.
Accompanying drawing 2 is that embodiment's steel cable inserts schematic representation.
Among the figure: 1, threading device; 2, breathing net; 3, connecting ring; 4, retaining ring; 5, rectangle joint; 6, steel cable.
As shown in the figure: its breathing net 2 one ends of threading device 1 are connecting rings 3, and the other end is an opening, and connecting ring 3 is with metal retaining ring 4 with breathing net 2 transition positions.Be pressed with rectangle joint 5 on the node of breathing net opening.Breathing net 2 is rhombus elastic metallic nets of multistrand rope interlacing.When the breathing net 2 of axial compression threading device 1,2 distortion of breathing net swell.Make steel cable 6 be easy to insert in the breathing net 2, when steel cable 6 is inserted into apart from retaining ring 4 positions 100～150mm, 3 places apply an axial tension at threading device 1 connecting ring, 2 contraction deformations of breathing net, taking off tight steel cable 6 moves threading device 1 and steel cable 1 together, when traction work was finished, axial compression breathing net 2 just desirablely went out steel cable 6.
Threading device 1 can use separately, also two threading devices 1 can be connected the back and use in pairs.Breathing net 2 can be selected the wire rope of minor diameter for use by the field of employment difference, and nylon rope or other chemical fiber rope are done braided fabric, and according to trailed weight, the braided fabric diameter can be coarse to fine.The shape of a mesh of breathing net 2 can also be made into square or other shape, knits the selected wire rope number of share of stock of breathing net, and according to the weight that is pulled thing, diameter is different and different, commonly used is 8,12,16,20 etc. strands.Per share available 1,2 or many braided fabrics.The diameter of breathing net 2 is according to being pulled the design of thing diameter, and the length of breathing net is by being pulled the design of thing weight, and the rectangle joint 5 that the End Node of breathing net is used can be that rectangular steel pipe, rectangle aluminum pipe or rectangle copper pipe are in case be scattered.The transition position of connecting ring 3, retaining ring 4, breathing net 2 can be with plastic sheath.Metal peach shape ring is housed in the connecting ring 3, and metal tube is equipped with at retaining ring 4 places, can make the stressed all even oarsman of preventing on the wire rope.Use product of the present utility model, can be safe and reliable steel cable 6 is passed sheave block smoothly, be applicable to that all need install or change the place of steel cable.
Below be threading device in use related parameter arranged:
| Model | The wire rope handling diameter | Length under the nature | To the steel cable clamping force |
| L-I | Φ9-Φ20 | 1400mm | 15000～30000N |
| JI-II | Φ20-Φ37 | 1600mm | 30000～40000N |
| JL-III | Φ38-Φ52 | 1700mm | 40000～50000N |
Using method:
With threading device 1 firmly radial compression make its distending, then steel cable 6 terminations are penetrated in the breathing net 2 of threading device as shown in Figure 2, breathing net 2 by joint compression threading device, steel cable 6 can be by joint deeply, treat steel cable 6 when retaining ring 100～150mm, just available threading device 1 passes sheave block with steel cable 6 tractions.In order to keep the elasticity of threading device 1, after using steel cable 6 is in time taken out from threading device 1, other article are tied up or lifted by crane to also not handy threading device 1.
