A cable pulling device for highway electromechanical applications

Abstract

This utility model relates to the field of cable pulling technology, specifically a cable pulling device for highway electromechanical applications. The advantages of this utility model are: the end of the cable is inserted into a conical receiving cylinder through a cable entry point, and then inserted between several clamping clamps. Rotating the conical guide cylinder drives the rotating disk and threaded sleeve to rotate, thereby driving the pull rod to pull several pulling rods, which in turn pull the clamping clamps towards the center, thus securing the cable. The conical transition structure between the conical receiving cylinder and the conical guide cylinder wraps around the junction of the cable and the pulling cable, making its insertion into the cable conduit smoother, reducing friction, and preventing jamming. Simply rotating the conical guide cylinder drives the rotating disk and threaded sleeve to rotate, which in turn drives the pull rod to pull several pulling rods, which in turn pull the clamping clamps towards the center, thus securing the cable. This facilitates cable fixation, is simple and convenient to operate, and improves operational ease.

Description

Technical Field

[0001] This utility model relates to the field of cable pulling technology, and in particular to a cable pulling device for highway electromechanical applications. Background Technology

[0002] With the continuous advancement of highway infrastructure construction in my country, highway electromechanical systems are increasingly widely used in traffic management, safety monitoring, and communication transmission. As a crucial component of electromechanical systems, the quality of cable laying and maintenance directly impacts the stability and reliability of system operation. Currently, cable pulling operations in highway electromechanical engineering primarily rely on manual dragging or mechanical traction.

[0003] Current manual or mechanical traction methods involve threading flexible cables through conduits, securing the cables, and then pulling them into the conduits. However, current cables are often secured using methods such as binding or bolting, which results in an uneven outer surface at the connection point. This friction during pulling within the conduit affects the pulling effect. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cable pulling device for highway electromechanical applications, which effectively solves the deficiencies of the prior art.

[0005] The purpose of this utility model is achieved through the following technical solution: A cable pulling device for highway electromechanical applications, comprising a fixed plate, a conical storage cylinder fixedly connected to one side of the fixed plate, a cable entry point at the tip of the conical storage cylinder, a threaded sleeve rotatably connected to the center of one side of the fixed plate inside the conical storage cylinder, a pull rod threadedly connected to the inner wall of the threaded sleeve, a pulling lug fixedly connected to the end of the pull rod near the cable entry point, and several connecting hinges fixedly connected to the edge of one side of the fixed plate inside the conical storage cylinder. The dry-connecting hinge is rotatably connected to several clamping clamps. Each clamping clamp has a connecting leaf fixedly connected to one side near the center of the conical storage cylinder. Each connecting leaf has a pull rod rotatably connected to its center. The pull rods are rotatably connected to a pull lug at their ends away from the connecting leaves. A rotating disk is fixedly connected to the outer wall of the threaded sleeve. A conical guide cylinder is fixedly connected to one side of the rotating disk away from the fixed disk. A connector is rotatably connected to the tip of the conical guide cylinder. A pull cable is fixedly connected to the center of the connector. The pull cable passes through the tip of the conical guide cylinder to the outside.

[0006] Preferably, in any of the above embodiments, the clamps are all located inside the conical storage cylinder, and the clamps are arranged in a radial ring array around the axis of the pull rod.

[0007] The technical effect achieved by adopting the above solution is that it enables several clamping pliers to clamp evenly from all sides towards the center.

[0008] Preferably, in any of the above solutions, the ends of the clamping pliers are arc-shaped structures, and the positions of the arc-shaped structures on the surfaces of the clamping pliers are all fixedly connected with a number of anti-slip teeth.

[0009] The technical effects achieved by adopting the above solution are: the arc-shaped structure facilitates cable insertion, while providing a certain inward pulling force during clamping to improve the clamping effect, and the anti-slip teeth enhance the firmness of the clamped cable.

[0010] Preferably, in any of the above solutions, the distance between the clamping clamps after they are brought together is less than the diameter of the cable entry point, and the distance between the outer sides of the clamping clamps and the inner wall of the conical storage cylinder after they are attached is adapted to the diameter of the cable entry point.

[0011] The technical effect achieved by adopting the above solution is that it enables cables within the diameter range of the cable entry point to be passed between several clamping clamps, thereby improving adaptability.

[0012] Preferably, in any of the above embodiments, the diameter of the fixed disk is adapted to the diameter of the rotating disk, and a damping pad is provided between the fixed disk and the rotating disk to dampen their rotation.

[0013] The technical effect achieved by adopting the above solution is that the damped rotation makes the rotating disk less prone to loosening after adjustment, thus improving stability.

[0014] Preferably, in any of the above embodiments, the diameter of the conical storage tube away from the tip is adapted to the diameter of the fixed disk, and the diameter of the conical guide tube away from the tip is adapted to the diameter of the rotating disk.

[0015] The technical effect achieved by adopting the above solution is to make the transition between the cone-shaped guide tube and the cone-shaped storage tube smooth, thereby improving the smoothness of guidance.

[0016] This utility model has the following advantages:

[0017] 1. This cable pulling device for highway electromechanical applications involves inserting the end of the cable through a cable entry point into a conical storage cylinder, which is then inserted between several clamping clamps. By rotating the conical guide cylinder, the rotating disk and threaded sleeve are driven to rotate, thereby driving the pull rod to pull several pulling rods, which in turn pull the clamping clamps to clamp the cable towards the center, thus securing the cable. During pulling, the conical transition structure of the conical storage cylinder and the conical guide cylinder wraps around the junction of the cable and the pulling cable, making the cable insertion and guidance in the cable tube smoother, with less friction and less likelihood of jamming.

[0018] 2. This cable pulling device for highway electromechanical applications involves inserting the cable through a cable inlet and then through a conical storage cylinder. The cable is then inserted between several clamping clamps. By rotating the conical guide cylinder, the rotating disc and threaded sleeve can be driven to rotate, thereby driving the pull rod to pull several pull rods, which in turn pulls several clamping clamps to clamp the cable towards the center, thus securing the cable. This method is simple and convenient to operate, improving ease of use. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0024] like Figures 1 to 3 As shown, a cable pulling device for highway electromechanical applications includes a fixed plate 1. A conical storage cylinder 2 is fixedly connected to one side of the fixed plate 1. The tip of the conical storage cylinder 2 has a cable entry point 3. A threaded sleeve 7 is rotatably connected to the center of one side of the fixed plate 1 inside the conical storage cylinder 2. A pull rod 8 is threadedly connected to the inner wall of the threaded sleeve 7. A pulling lug 9 is fixedly connected to the end of the pull rod 8 near the cable entry point 3. Several connecting hinges 11 are fixedly connected to the edge of one side of the fixed plate 1 inside the conical storage cylinder 2. The fixed plate 1 is rotatably connected to several... Clamping clamps 12, several clamping clamps 12 are fixedly connected to connecting pages 13 on one side near the center of the conical storage cylinder 2, several connecting pages 13 are rotatably connected to the center of the connecting pages 13, several pulling rods 10 are rotatably connected to the end of the pulling rods 10 away from the connecting pages 13, and a pulling ear 9 is rotatably connected to the outer wall of the threaded sleeve 7. A rotating disk 4 is fixedly connected to the outer wall of the rotating disk 4 away from the fixed disk 1, a conical guide cylinder 5 is fixedly connected to the side of the rotating disk 4 away from the fixed disk 1, a connector 15 is rotatably connected to the tip of the conical guide cylinder 5, a pulling cable 6 is fixedly connected to the center of the connector 15, and the pulling cable 6 passes through the tip of the conical guide cylinder 5 to the outside.

[0025] As an optional technical solution of this utility model: several clamping pliers 12 are all located inside the conical storage cylinder 2, and several clamping pliers 12 are arranged in a radial ring array around the axis of the pull rod 8, so that several clamping pliers 12 can clamp evenly from the periphery to the center.

[0026] As an optional technical solution of this utility model: the ends of several clamping pliers 12 are arc-shaped structures, and several anti-slip teeth 14 are fixedly connected to the positions of the arc-shaped structures on the surfaces of several clamping pliers 12. The arc-shaped structure facilitates cable insertion, and at the same time provides a certain inward pulling force when clamping, thereby improving the clamping effect. Meanwhile, the several anti-slip teeth 14 improve the firmness of the clamped cable.

[0027] As an optional technical solution of this utility model: the distance between several clamping pliers 12 after they are aggregated is less than the diameter of the cable entry 3, and the distance between the outer sides of several clamping pliers 12 and the inner wall of the conical storage cylinder 2 after they are attached is adapted to the diameter of the cable entry 3, so that the cables within the diameter range of the cable entry 3 can be passed between several clamping pliers 12, thereby improving adaptability.

[0028] As an optional technical solution of this utility model: the diameter of the fixed disk 1 is adapted to the diameter of the rotating disk 4, and a damping pad is provided between the fixed disk 1 and the rotating disk 4. The fixed disk 1 and the rotating disk 4 rotate with damping. Through damping rotation, the rotating disk 4 is not easy to loosen after rotation adjustment, thus improving stability.

[0030] The working process of this utility model is as follows: When the user uses it...

[0031] 1) Pass the end of the cable through the cable inlet 3 into the conical storage tube 2, and then insert it between several clamping pliers 12;

[0032] 2) Then, by rotating the conical guide cylinder 5, the rotating disk 4 and the threaded sleeve 7 can be driven to rotate, thereby driving the pull rod 8 to pull several pull rods 10, which in turn pulls several clamping clamps 12 to clamp towards the center, thereby gripping the cable.

[0033] 3) During the pulling process, the conical transition structure of the conical storage cylinder 2 and the conical guide cylinder 5 wraps the junction of the cable and the pulling cable 6. Then, the pulling cable 6 pulls the conical guide cylinder 5 back into the conduit, thereby bringing the cable into the conduit.

[0034] In summary, this utility model allows the cable end to be inserted into the conical storage cylinder 2 through the cable entry point 3, and then inserted between several clamping pliers 12. Rotating the conical guide cylinder 5 drives the rotating disk 4 and threaded sleeve 7 to rotate, thereby causing the pull rod 8 to pull several pulling rods 10, which in turn pulls the clamping pliers 12 to clamp towards the center, thus securing the cable. During pulling, the conical transition structure of the conical storage cylinder 2 and the conical guide cylinder 5 wraps around the junction of the cable and the pulling cable 6, making the cable insertion into the conduit smoother, reducing friction, and preventing jamming. Simply rotating the conical guide cylinder 5 drives the rotating disk 4 and threaded sleeve 7 to rotate, thereby causing the pull rod 8 to pull several pulling rods 10, which in turn pulls the clamping pliers 12 to clamp towards the center, thus securing the cable. This method is simple and convenient, improving operational ease.
