Description

Technical Field

[0001] This utility model relates to the field of cable traction technology, and in particular to a cable traction device for cable installation. Background Technology

[0002] Cables are an important tool for power transmission. To ensure the effective transmission of power in cable lines, cable laying is crucial. During cable laying, the cable needs to be taken out of the reel and transported and pulled. When pulling the cable, the cable head is inserted into the cable mesh sleeve, and then the rope sleeve at the other end of the cable mesh sleeve is connected to the cable winch by a steel wire rope for cable installation and pulling.

[0003] In existing cable mesh sleeves, the cable typically relies on the shrinkage and tightening of the sleeve to hold the cable during traction. However, the sleeve body of such cable wire mesh sleeves is relatively simple. When the wire mesh sleeve encounters intermittent tension during cable traction, the cable and the wire mesh sleeve are prone to loosening, which can lead to the cable falling off during traction and thus affect the cable threading and installation. Therefore, we propose a cable traction device for cable installation. Utility Model Content

[0004] The main objective of this invention is to provide a cable traction device for cable installation. A retraction mechanism is installed at the wire mesh sleeve on one side of the rope sleeve. This retraction mechanism, through the cooperation of a C-shaped main clamp and a C-shaped auxiliary clamp, and the mutual clamping of the C-shaped teeth and C-shaped auxiliary teeth fixed inside them, firmly clamps the cable, ensuring that the cable will not slip or be damaged during traction. This improves the stability and safety of cable traction operations. Furthermore, the wire mesh sleeve of the retraction mechanism, in conjunction with the rubber ring, can tightly adhere to the cable, providing stable traction force, effectively solving the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable pulling device for cable installation includes a rope sleeve and a wire mesh sleeve. The wire mesh sleeve is installed on one side of the rope sleeve. The device also includes a retraction mechanism, which comprises a wire rope loop, a wire strip A, a C-shaped main hoop, a C-shaped auxiliary hoop, a perforated plate A, a perforated plate B, a C-shaped clamp, a C-shaped fitting, a wire strip B, and a wire rear sleeve. A wire rope loop is wound around the larger opening of the wire mesh sleeve away from the rope sleeve. The outer side of the wire rope loop is fixed to the C-shaped main hoop and the C-shaped auxiliary hoop via the wire strip A. Perforated plates A and B are fixed to the two ends of the C-shaped main hoop and the C-shaped auxiliary hoop, respectively. A bolt extends between the perforated plates A and B, and a nut is screwed onto the bolt extending from the bolt body of the perforated plate B. C-shaped clamps and C-shaped fittings are fixed to the inner walls of the C-shaped main hoop and the C-shaped auxiliary hoop, respectively. A wire rear sleeve is fixed to the side of the C-shaped auxiliary hoop away from the wire strip A via the wire strip B.

[0007] Furthermore, a rubber ring is bonded to the rear sleeve opening away from the steel wire strip B;

[0008] By adopting the above technical solution, the steel wire is elastically wrapped around the outside of the cable with a rubber ring.

[0009] Furthermore, two sets of the C-shaped retaining teeth are arranged and fixed inside the C-shaped main clamp;

[0010] By adopting the above technical solution, the C-shaped main clamp can firmly clamp the cable with two sets of C-shaped teeth.

[0011] Furthermore, two sets of C-shaped fitting teeth are arranged and fixed within the C-shaped clamp;

[0012] By adopting the above technical solution, the C-shaped clamp can firmly clamp the cable with two sets of C-shaped teeth.

[0013] Furthermore, the surfaces of the perforated plates A and B are perforated, and bolts protrude from the perforated plates A and B.

[0014] By adopting the above technical solution, bolts can pass through the holes in orifice plate A and orifice plate B, and then the bolts can be tightened with nuts.

[0015] Furthermore, eight sets of steel wires B are fixed between the steel wire rear sleeve and the C-shaped clamp;

[0016] By adopting the above technical solution, the steel wire sleeve and the C-shaped clamp are firmly connected by multiple sets of steel wire strips B.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides a retraction mechanism at the wire mesh sleeve on one side of the rope sleeve. The retraction mechanism uses the cooperation of the C-shaped main hoop and the C-shaped auxiliary hoop, as well as the mutual cooperation of the C-shaped clamping teeth and C-shaped auxiliary teeth fixed inside them, to firmly clamp the cable and ensure that the cable will not slip or be damaged during the traction process, thereby improving the stability and safety of cable traction operations.

[0019] Furthermore, the steel wire sleeve of the retraction mechanism, together with the rubber ring, can fit tightly against the cable, providing stable traction. In addition, the rubber ring can also protect the cable. This retraction mechanism, together with the steel wire mesh sleeve, can efficiently transmit traction, ensuring that the cable can be pulled smoothly and quickly to the designated position. This helps to improve the efficiency of cable installation and construction, and reduce labor and time costs. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-2As shown, a cable pulling device for cable installation includes a rope sleeve 1 and a wire mesh sleeve 2. The wire mesh sleeve 2 is installed on one side of the sleeve body of the rope sleeve 1. It also includes a retraction mechanism 3, which includes a wire rope loop 4, a wire strip A5, a C-shaped main clamp 6, a C-shaped auxiliary clamp 7, a perforated plate A8, a perforated plate B9, a C-shaped clamp 12, a C-shaped auxiliary clamp 13, a wire strip B14, and a wire rear sleeve 15. The wire mesh sleeve 2 has the wire rope loop 4 wound around its larger opening away from the rope sleeve 1, and the outer side of the wire rope loop 4 is connected by a steel... C-shaped main clamp 6 and C-shaped auxiliary clamp 7 are fixed to wire A5 respectively. Hole plate A8 and hole plate B9 are fixed to both ends of the clamp body of C-shaped main clamp 6 and C-shaped auxiliary clamp 7 respectively. Bolt 10 passes through hole plate A8 and hole plate B9. Nut 11 is screwed to the bolt body of hole plate B9. C-shaped clamp 12 and C-shaped auxiliary clamp 13 are fixed to the inner clamp wall of C-shaped main clamp 6 and C-shaped auxiliary clamp 7 respectively. Steel wire sleeve 15 is fixed to the side of C-shaped auxiliary clamp 7 away from the wire A5 through steel wire B14.

[0025] Among them, a rubber ring 16 is glued to the rear opening of the steel wire sleeve 15 away from the steel wire strip B14;

[0026] By adopting the above technical solution, the steel wire sleeve 15 is elastically wrapped around the outside of the cable with a rubber ring 16.

[0027] Among them, two sets of C-shaped locking teeth 12 are arranged and fixed inside the C-shaped main clamp 6;

[0028] By adopting the above technical solution, the C-shaped main clamp 6 can firmly clamp the cable with two sets of C-shaped clamping teeth 12.

[0029] Among them, two sets of C-shaped fitting teeth 13 are arranged and fixed inside the C-shaped fitting clamp 7;

[0030] By adopting the above technical solution, the C-shaped clamp 7 can firmly clamp the cable with two sets of C-shaped teeth 13.

[0031] Wherein, the perforated plates A8 and B9 are perforated through the surface of the plates, and the bolts of the bolts 10 protrude through the perforated plates A8 and B9.

[0032] By adopting the above technical solution, the holes in the orifice plate A8 and the orifice plate B9 can be passed through the bolt 10, and then the bolt 10 can be screwed onto the nut 11 for locking.

[0033] Among them, eight sets of steel wire strips B14 are fixed between the steel wire sleeve 15 and the C-shaped clamp 7;

[0034] By adopting the above technical solution, the steel wire sleeve 15 and the C-shaped clamp 7 are firmly connected by multiple sets of steel wire strips B14.

[0035] It should be noted that this utility model is a cable pulling device for cable installation. A retraction mechanism 3 is set at the wire mesh sleeve 2 on one side of the rope sleeve 1. After the wire rope loop 4 of the retraction mechanism 3 is welded and sealed at the end of the wire mesh sleeve 2, the wire rope sleeve 4 is welded with a C-shaped main hoop 6 and a C-shaped auxiliary hoop 7 by a wire strip A5. The C-shaped auxiliary hoop 7 is connected to the wire rear sleeve 15 by a wire strip B14. When the cable needs to be pulled and installed, the cable head can pass through the wire rear sleeve 15, and then the cable head continues to pass between the C-shaped main hoop 6 and the C-shaped auxiliary hoop 7. Then the cable head can pass through the wire rope loop 4 and enter the wire mesh sleeve 2. The rope sleeve 1 can be connected to the cable winch for pulling by a wire rope. Before pulling, the bolt 10 can pass through the orifice plate A8 and the orifice plate B9 and be screwed on. Nut 11 is used to press the C-shaped main clamp 6 and C-shaped auxiliary clamp 7 against the outside of the cable. At the same time, the C-shaped teeth 12 at the C-shaped main clamp 6 and the C-shaped teeth 13 at the C-shaped auxiliary clamp 7 can bite and lock the cable in multiple ways, thus ensuring that the cable inserted through the wire mesh sleeve 2 is not prone to falling off during traction. After the cable is pulled, nut 11 is unscrewed from bolt 10, and bolt 10 can be pulled out from the orifice plate A8 and orifice plate B9. Then, the C-shaped main clamp 6 and C-shaped auxiliary clamp 7 are opened in opposite directions, and the wire mesh sleeve 2 is pushed towards the rope sleeve 1, so that the wire mesh sleeve 2 is stacked and the cable is released. At this time, the cable can be pulled out from the wire mesh sleeve 2. Similarly, the cable can be released after stacking at the wire mesh sleeve 15, so that the cable can be pulled out and the retraction mechanism 3 and the wire mesh sleeve 2 can be installed.
