Description

Technical Field

[0001] The present application belongs to the technical field of cable production equipment, and in particular, relates to a cable crawler traction machine. Background Art

[0002] The extrusion process in cable production is as follows: the conductor or wire is wound on the cable drum of the pay-off device, extruded by the extruder and cooled by water, then passed through the crawler traction machine, and finally the take-up device takes the extruded cable to another cable drum on the take-up device; in the whole process, the cable is moved forward by the traction force of the crawler traction machine.

[0003] Crawler tractors are generally provided with an emergency stop switch for stopping the crawler tractor in an emergency. However, in the crawler tractor of the prior art, after the emergency stop switch is pressed, the power supply of the crawler tractor is only cut off. In this way, the cable drum at the pay-off device will continue to rotate and pay-off due to inertia, thereby causing the cable to sag and fall. Once the newly extruded cable falls to the ground and sticks to the dust on the ground, it may be scrapped. Utility Model Content

[0024] In order to cooperate with the crawler 2.2 traction machine, we also need to set a second emergency stop switch 7.6 on the pay-off device 7. The pay-off device 7 includes a cable drum 7.1 and a cable drum fixing frame 7.2 on which the cable drum 7.1 is placed. The cable drum fixing frame 7.2 is provided with a brake disc 7.3 connected to the cable drum 7.1.

The brake assembly 7.5 includes an installation box 7.5.1, a brake motor installed in the installation box 7.5.1, a transmission rod 7.5.2 driven by the brake motor, and a brake pad 7.5.3 hinged to the transmission rod 7.5.2.

[0026] Working principle: When an emergency occurs on site and an emergency stop is required, press the first emergency stop switch, and the upper and lower hydraulic cylinders will shrink at the same time, so that the upper and lower pressure wheel assemblies leave the track, and then the track releases the cable, and the cable loses the power to pull forward; at the same time, after the second wireless module receives the command, the brake motor starts to move, driving the transmission rod, and then depositing the brake pad on the brake pad, stopping the cable reel and preventing the cable from falling; due to the contraction of the lower hydraulic cylinder, the lower track is easy to loosen from the traction wheel. At this time, the lower pressure wheel assembly with a spring set at the lower part loosens the cable but can still support the track.

[0027] The present application sets a second emergency stop switch at the wire-releasing device, and the first emergency stop switch and the second emergency stop switch set on the crawler traction machine are connected through a wireless module. When the first emergency stop switch is pressed, the second emergency stop switch will also be triggered in conjunction with it after 0.5-1 second; after the first emergency stop switch is pressed, the telescopic rods of the upper hydraulic cylinder and the lower hydraulic cylinder will retract, so that the upper and lower belts are separated, and the cable is no longer pulled; the second emergency stop switch can control the brake pads to stop the brake disc, thereby stopping the cable reel, thereby preventing the cable from falling.

[0028] In the cable crawler traction machine of the present application, two of the lower pressure wheel assemblies are connected to the lower hydraulic cylinder via springs; thereby ensuring that when the lower hydraulic cylinder is retracted, the two pressure wheels can still play a role in supporting the crawler.

[0029] Although the present invention has been illustrated and described with respect to preferred embodiments, those skilled in the art will appreciate that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
