Control device for remotely operating electric shovel to move downwards and be finely adjusted

Abstract

The invention discloses a control device for remotely operating an electric shovel to move downwards and be finely adjusted. The control device comprises a normal start-stop device, a man-machine operation platform, an emergency stop button TA023, a total button QA022, a left walking controller and a right walking controller, wherein the output end of the normal start-stop device is electrically connected with the input end of an electric shovel start-stop device, and the input end of the normal start-stop device is electrically connected with the left walking controller and the right walking controller; and an original electric shovel control system on the electric shovel is utilized, the wiring mode is changed, the control device is connected with an electrical control system, the control device is operated and controlled, the control device remotely controls a lower mechanism of the electric shovel to move and be finely adjusted, the fine operation of movement of the lower mechanism and the unmanned operation on equipment are achieved, and major potential safety hazards are avoided. The control device is used for conducting remote fine operation, the advantages that the movement speed is controllable, and the movement position is adjustable are achieved, the position precision of movement of the lower mechanism is improved, and the centering error is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of control devices for coal mine electric shovel equipment, in particular to a control device for remote operation of electric shovel down movement and fine adjustment. Background technique [0002] During the overhaul of the WK series variable frequency electric shovel, it is usually necessary to separate the upper mechanism of the electric shovel (the part of the rotary platform) from the lower mechanism (the part of the traveling mechanism and the underframe beam), and remove the lower mechanism for maintenance. The traditional moving method is to take the way of dragging, that is, firstly untie the track shoes of the traveling mechanism, and then lift the upper mechanism (slewing platform) to an appropriate height, and then use construction machinery to pull the lower mechanism out, and the lower mechanism (traveling mechanism) and underframe beam) after the overhaul is completed, it will be moved in by ...

AI Technical Summary

Problems solved by technology

[0003] The existing method is rough in operation, requires a lot of auxiliary equipment and personnel, and cannot accurately control the moving speed and position of the lower mechanism by using the dragging method, which poses a great potential safety hazard on site

The position of the lower mechanism cannot be adjusted when there is a deviation in the centering fall of the upper mechanism, which will affect the alignment accuracy and easily damage the connecting parts (central shaft and bushing) of the upper and lower mechanisms, resulting in greater losses
