Tension adjusting device and method for steel wire ropes of bidirectional traction type rail transport machine

Abstract

The invention relates to a tension adjusting device and method for steel wire ropes of a bidirectional traction type rail transport machine. The adjusting device comprises a tension adjusting mechanism and a control system, wherein the tension adjusting mechanism comprises a motor, a lead screw, a lead screw nut and a tension sensor, an output shaft of the motor is connected with the lead screw, the lead screw nut is connected onto the lead screw, one end of the tension sensor is connected with the lead screw nut, the other end of the tension sensor is connected with a mounting base of a winch in the bidirectional traction type rail transport machine, and the mounting base is connected with a supporting frame fixed on the ground through a linear sliding mechanism; the control system comprises a signal feedback unit, a control unit, an execution unit and a power supply, the signal feedback unit consists of the tension sensor, and the execution unit consists of the motor. With the adoption of the adjusting device, the tension of the steel wire ropes can be adjusted automatically in real time, so that the steel wire ropes are in the optimal tensioned state all the time.

Description

technical field [0001] The invention relates to transportation equipment for mountain orchards, in particular to a device and method for adjusting the tension of a wire rope of a two-way traction rail conveyor. Background technique [0002] In the invention patent application with the application number 201210232143.6 and the announcement number CN102730006A, a "wire rope two-way traction type mountain orchard freight system" is provided. The patent application scheme has been installed and tested in Yongchun, Fujian, Zhongxian, Chongqing and other places in my country. The transportation capacity of agricultural materials such as fruits, pesticides and fertilizers in local orchards has been improved. This technical solution is especially suitable for orchards with steep slopes, small slopes or even no slopes. The slope adaptability is strong, but the wire rope tensioning device of the mountain orchard wire rope two-way traction track conveyor that has been installed and test...

AI Technical Summary

Problems solved by technology

This technical solution is especially suitable for orchards with steep slopes, small slopes or even no slopes. The slope adaptability is strong, but the wire rope tensioning device of the mountain orchard wire rope two-way traction track conveyor that has been installed and tested is purely mechanical. , the driving device needs to move back and forth under the action of artificially rotating the screw to complete the tensioning of the wire rope. The purpose is to make the wire rope not easy to slip in the drum to improve the traction performance of the conveyor; It has a large elasticity, and it will automatically relax after a period of use. It needs to be manually adjusted frequently, which is more cumbersome to realize. Second, manual adjustment cannot accurately control the tension of the wire rope. If it is too loose, the wire rope will be in the drum. Severe slipping, reduced traction performance, and increased wear of the wire rope; too tight will increase traction resistance, reduce traction performance, increase energy consumption, and reduce the service life of the wire rope
