Abstract

Disclosed is a protective device of a displacement sensor. The protective device comprises a fixed assembly, a sliding assembly and the displacement sensor; the fixed assembly is provided with a closed cavity for placing the displacement sensor; the opening in the bottom of the closed cavity of the fixed assembly is blocked by the sliding assembly, and the displacement sensor in the fixed assembly is connected with the sliding assembly, so that the sliding assembly drives the displacement sensor to slide up and down in the closed cavity of the fixed assembly, and displacement measurement is achieved. The protective device of the displacement sensor is fixed between a cylinder barrel of a leveling oil cylinder and a piston rod of the leveling oil cylinder by the fixed assembly and the sliding assembly, and the displacement sensor is arranged inside the fixed assembly and the sliding assembly, so that the displacement sensor is installed in a closed mode and prevented from being influenced by external environment, and meanwhile the synchronous movement and measurement of the displacement sensor and the piston rod of the leveling oil cylinder are achieved.

Description

technical field

[0001] The invention relates to the technical field of automatic control of a belt self-moving tail, in particular to a displacement sensor protection device and a belt self-moving tail provided with a displacement sensor. Background technique

[0002] The belt self-moving machine tail is the transport equipment along the trough of the fully mechanized mining face. It connects the bridge loader and the belt conveyor along the trough. The machine is a fulcrum for each other, realizing the self-moving action of stepping, and at the same time, it can correct the deviation between the machine body and the center line of the belt, and realize the function of belt leveling and deviation adjustment. However, the existing belt self-moving machine tails are all manually operated, requiring operators to observe with the naked eye and manually adjust the expansion and contraction of the leveling cylinder to realize the leveling function of the belt.
