Mining anchor withdrawing vehicle

Abstract

The invention discloses a mining anchor withdrawing vehicle. A mechanical arm is installed at a head of a carriage through a rotary support, can rotate in situ, can swing up and down and can stretch out and draw back for multiple sections, an anchor withdrawing device is fixed to the mechanical arm, can swing left and right, can swing up and down, is supported in a lifting mode, can stretch out and draw back vertically and abuts against a mine tunnel top plate and the ground, and a driving system enables a crawler belt to advance; an oil supply system controls all oil cylinders and motors to act, a cooling system reduces the working temperature of hydraulic oil and a machine head, a searchlighting system adjusts lighting and camera shooting angles, a sensing system detects the peripheral distance, the temperature of the hydraulic oil and the concentration of methane, and an alarm system can give out sound-light alarms. The central control system converts a remote control instruction received by the communication system into an electromechanical control signal, sends the electromechanical control signal to other systems, and feeds back collected operation data to a remote control center through the communication system.

Description

technical field [0001] The invention belongs to the technical field of engineering operations, and in particular relates to a sensing remote control technology. Background technique [0002] After the mining operation is over, the whole cross-drop method is generally used to deal with the goaf roof. In order to prevent secondary accidents in the large-area suspended roof in the gob area of ​​the working face and excessive pressure at the moment of falling, it is necessary to remove the anchor rods and anchor cables in time to allow the roof to collapse in time. [0003] Set up a ladder during operation, the operator above lifts the anchor retractor or cutter over the head, finds a suitable position on the roof, hangs it to the steel beam on the roof with a safety rope, pulls it to the working position, and pulls the anchor cable, anchor, The anchor ring is threaded into the dissector and held in place. The operator at the bottom pressurizes and clamps the oil cylinder, and...

AI Technical Summary

Problems solved by technology

[0004] The existing cutting methods require manual hand-held fixation, and although some can be operated remotely, they still require manual on-site control

Because it is all manual work, there are safety hazards such as bruises, smashes, collapses, etc.

Each operation process is cumbersome, time-consuming, and work efficiency is low

Existing anchor withdrawal equipment is bulky, cannot be separated from manual driving, and cannot adapt to the dark and narrow mine tunnel environment
