Problems solved by technology

[0003] In the existing coal mine system, the cage is only responsible for transporting people or equipment, but does not have the function of automatic judgment. In the field construction, because these equipment do not have the function of automatic judgment, it is easy to cause some safety hazards and affect the life safety of workers.

Embodiment Construction

[0034] The technical solution of the present invention will be described in further detail below in the form of examples. It should be noted that the examples are only specific illustrations of the present invention, and are not intended to limit the present invention.

[0035] In order to improve the safety of the coal mine system, accurately control the closure of the cage door and the guardrail in the coal mine system, ensure that the number of people entering and leaving the coal mine system is consistent, and prevent safety accidents, the invention provides a detection method for the cage door and the guardrail, including Following steps,

[0036] (1) There is a first monitoring point on the guardrail;

[0037] (2) Carry out the first guardrail inspection on the guardrail through the first monitoring point, and judge the switch state of the guardrail; if the guardrail is in the closed state, continue to monitor, and if the guardrail is in the unclosed state, send an alarm...

Abstract

The invention discloses a detecting method for a cage door and protective guard. Five detection points are arranged on the cage and the protective guard correspondingly, and used for supervising the closing situation of the protective guard, the closing condition of the cage door, the gap situation between the cage door and the protective guard and the inner environment of the cage. Through arrangement of a plurality of detection devices, the cage door and the protective guard can be self-detected, the abnormity can be timely fed back, and the production efficiency and the labor safety are improved.

Description

technical field [0001] The invention relates to a detection method of a cage door and a protective fence, in particular to a detection method of a cage door and a protective fence of a coal mine system. Background technique [0002] The safety of the coal mine system is no small matter. The most important and basic thing for the safety of the coal mine system is to ensure the safety of personnel entering the coal mine system. Cages are generally used for lifting the auxiliary shaft of the mine to lift personnel, ore, equipment, materials, etc. For small and medium-sized mines, the cage can also be used as a main shaft hoist for lifting coal, and the cage is one of the important equipment in mine hoisting. [0003] In the existing coal mine system, the cages are only responsible for transporting people or equipment, but do not have the function of automatic judgment. In the field construction, because these equipment do not have the function of automatic judgment, it is easy ...
