Abstract

The invention relates to the technical field of safety devices of drilling machines, in particular to an emergency stop device of a drilling machine with a brake. The emergency stop device of the drilling machine with the brake comprises a normally open gas control valve, a gas source gas intake pipeline, a button gas switch and a brake gas cylinder, wherein a first normally open port of the normally open gas control valve is communicated with the gas source gas intake pipeline through a first pipeline; a second pipeline is fixedly connected to a second normally open port of the normally open gas control valve; a control port of the normally open gas control valve is communicated with the gas source gas intake pipeline through a third pipeline; the button gas switch is fixedly mounted on the first pipeline; the control port of the normally open gas control valve is communicated with the brake gas cylinder through a fourth pipeline; a reversing valve and a quick gas discharging valve are fixedly mounted on the fourth pipeline from right to left. The emergency stop device is reasonable and compact in structure and convenient to use; during the normal drilling operation, compressed gas provided by a gas source drives the drilling machine to operate through the normally open gas control valve; when the drilling machine needs to emergently stop, the button gas switch is pressed down, the compressed gas provided by the gas source enters the brake gas cylinder, a brake function is realized, and the safety of personnel and equipment is protected.

Description

technical field [0001] The invention relates to the technical field of safety devices for drilling rigs, and relates to an emergency stop device for drilling rigs with brakes. Background technique [0002] At present, mechanical belt brake drilling rigs are not equipped with a manual emergency stop device. When they need to be stopped in an emergency, they can only be stopped by the anti-collision device, which cannot ensure safe production and has potential safety hazards. Therefore, designing an emergency shutdown device on the driller's console, and in an emergency, manually shutting down becomes a problem to be solved urgently by those skilled in the art. Contents of the invention [0003] The present invention provides an emergency stop device for drilling rigs with brakes, which overcomes the above deficiencies in the prior art, and can effectively solve the problems of existing mechanical drilling rigs with brakes that are not equipped with a manual emergency stop d...
