Description

Anti-traction rope jumping device

technical field

The utility model belongs to the technical field of transmission line stringing construction, and in particular relates to a slot-jumping device for preventing traction ropes.

Background technique

In the wire construction of transmission lines in the electric power industry, the tension machine is an indispensable equipment. Because the traction rope on the tension machine appears a cycloid during traction, the phenomenon of traction rope jumping often occurs, which seriously affects the construction efficiency and construction safety.

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides an anti-traction rope skipping device for preventing the traction rope on the tensioner from skipping during construction.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: the anti-traction rope slot-jumping device includes a mounting frame, an outer square tube arranged horizontally on the mounting frame, an inner square tube coaxially arranged in the outer square tube, and an inner square tube arranged in the outer square tube. The spring with radial torsion is set outside the inner square tube. In the center of the inner square tube, there is a fixing bolt that connects the outer tube and one end of the inner square tube to the mounting frame. The other end of the fixing bolt is equipped with a swing arm. The upper part of the arm is provided with a handle, and the lower part of the swing arm is provided with a roller mechanism.

The roller mechanism includes a roller rotatably connected to one side of the lower part of the swing arm and a connecting rod hinged on the swing arm, and the other end of the connecting rod is provided with a stop iron.

The lower part of the installation frame is provided with a support frame.

By adopting the above technical scheme, the traction rope on the stretching machine is passed through the rope groove of the roller of the roller mechanism. When the traction rope is swinging, the roller effectively prevents the possibility of the traction rope jumping on the stretching machine. The impact force on the roller is transmitted to the spring through the swing arm, and the radial torsion of the spring itself is reversely transmitted to the roller and pressed against the traction rope to prevent damage to the roller and swing arm; pull out the rope before coiling The connecting rod hinged on the swing arm, pull the handle and use the iron stopper to keep a proper gap between the roller and the traction wheel for rope winding; the support frame is used to set the mounting frame on the base of the stretcher side. The utility model has a simple structure, is easy to manufacture and is convenient to install, effectively avoids the phenomenon of the traction rope jumping on the stretcher during the construction of the transmission line, greatly improves the safety performance and construction efficiency of the stretcher, and has strong practicability. It is worth promoting the application.

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, the anti-traction rope slot-hopping device of the present utility model includes a mounting frame 1, a support frame 2 arranged at the bottom of the mounting frame 1, an outer square tube 3 horizontally arranged on the mounting frame 1, an outer The inner square tube 4 coaxially arranged in the square tube 3 and the spring 5 with radial torsion force outside the inner square tube 4 that are set in the outer square tube 3 are set. The spring 5 is made of rubber material, and the center of the inner square tube 4 is set. There is a fixing bolt 6 fixedly connecting one end of the outer square pipe 3 and the inner square pipe 4 with the mounting frame 1, the other end of the fixing bolt 6 is provided with a swing arm 7, the upper part of the swing arm 7 is provided with a handle 8, and the lower part of the swing arm 7 is provided with a handle 8. Has a roller mechanism. The roller mechanism comprises a roller 9 rotatably connected to one side of the lower part of the swing arm 7 and a connecting rod 10 hinged on the swing arm 7 , the other end of the connecting rod 10 is provided with a stop iron 11 . The cross sections of the outer square tube 3 and the inner square tube 4 are square structures.

During work and use, the support frame 2 is fixed on the base on one side of the stretcher, and the rope groove 12 of the roller 9 is basically aligned with the rope groove on the stretcher. In the rope groove 12 of the roller 9, when the traction rope is swinging, the roller 9 effectively prevents the possibility of the traction rope jumping on the stretching machine, and the roller 9 will receive a relatively large impact force, which is transmitted through the swing arm 7 On the spring 5, the radial torsion force of the spring 5 itself is reversely transmitted to the roller 9 and pressed to the traction rope, which also prevents the damage of the roller 9 and the swing arm 7; before winding the rope, the swing arm 7 should be pulled out and hinged The connecting rod 10 is used to pull the handle 8 and utilize the stop iron 11 to keep an appropriate gap between the roller 9 and the traction wheel so as to wind the rope.
