Travel limiting alarm device for bridge stage loader

Abstract

A travel limiting alarm device for a bridge stage loader is installed on a tail buffer beam of a transfer belt conveyer of the bridge stage loader of a tunneling machine and is 500 mm away from the tail end of a track; the travel limiting alarm device sends out an acousto-optic danger warning when travel wheels of the bridge stage loader of the tunneling machine contact an anti-explosion limit switch. The travel limiting alarm device is highly operable and convenient to use. An anti-explosion acousto-optic electric whistle alarm device is hung to a position 2.5 m off the inner sidewall of a tail buffer rack of the belt conveyer; a steel frame of the alarm device is locked to the tail buffer rack of the belt conveyer through two U-shaped clamps and is equivalently fixed to a travel track of the bridge stage loader; one anti-explosion travel switch is mounted in an outer channel of the steel frame; when rolling wheels contact the anti-exposition limit switch button stem during traveling of the tunneling machine, a power loop of the acousto-optic alarm device may be made to give out a danger warning signal; when a driver of the tunneling machine receives the danger warning signal, the driver stops the tunneling machine immediately from continuously moving forward for operation.

Description

technical field [0001] The patent of the present invention relates to an underground tunneling machine in a coal mine. During the working process, the coal or gangue excavated by the tunneling machine is transferred to the belt conveyor through the rear supporting bridge type transfer machine of the tunneling machine, and the bridge type transfer machine is on the belt conveyor Running on the tail slide. The problem of how to limit the bridge type loader when it is running on the belt conveyor runway, after setting the limit, solves the problem of unsafe operation of the bridge type loader. Background technique [0002] In view of the fact that the coal mine underground roadheader needs to move back and forth, left and right frequently during the process of cutting coal, it is necessary to arrange special personnel to guard the operating position of the bridge-type reloader during the running time, and manually send a signal to the roadheader driver. The noise is loud durin...

Problems solved by technology

[0002] In view of the fact that the coal mine underground roadheader needs to move back and forth, left and right frequently during the process of cutting coal, it is necessary to arrange special personnel to guard the operating position of the bridge-type reloader during the running time, and manually send a signal to the roadheader driver. There is a lot of noise during operation, and the instructions issued by manpower are not clear, which causes the bridge loader to run too far, damage the equipment, and may cause personal injury accidents
