Embodiment 1

[0056] Such as Figure 1-2 shown.

[0057] A hydraulic support posture and straightness detection system, comprising a hydraulic support posture detection system, a posture signal transmission cable 6 and a computer processing system 4; the hydraulic support posture detection system communicates with the computer through the posture signal transmission cable 6 The system 4 is connected; the hydraulic support posture detection system is arranged between two adjacent hydraulic supports in the coal mining face; the hydraulic support posture detection system includes a relative posture detection device and a mounting plate 3, and the mounting plate 3 are arranged at both ends of the relative pose detection device; the two mounting plates 3 are respectively fixed and arranged on two adjacent hydraulic supports;

[0058] The relative pose detection device includes an elastic bellows 2.3, a wire-type sensor fixing box 2.6 and a wire rope end fixing box 2.9; the guy wire sensor fixin...

Embodiment 2

[0062] As in the hydraulic support posture and straightness detection system described in Embodiment 1, the difference is that the number of the stay-wire displacement sensors 2.1 is 9, and every 3 stay-wire displacement sensors 2.1 are a group; Type hub fixed plate 2.2 is provided with three anti-abrasion type rope collectors 2.7, and rope collector fixed plate 2.4 is provided with three rope collectors 2.8; The steel wire rope that each group of pull-type displacement sensors 2.1 draws passes through the same anti-wear type rope collector. The rope device 2.7, the steel wire ropes passing through the same wear-resistant type rope collector 2.7 pass through different rope collectors 2.8 respectively and are connected with different wire rope fixers 2.5.

Embodiment 3

[0064] As in the hydraulic support posture and straightness detection system described in Embodiment 1, the difference is that the anti-wear type rope collector fixing plate 2.2 is arranged in parallel with the side wall of the pull wire sensor fixing box 2.6; The device fixing plate 2.4 is arranged in parallel with the side wall of the wire rope end fixing box 2.9.

Abstract

The invention relates to a hydraulic support pose and linearity detection system and a work method thereof. According to the device, multiple guyed displacement sensors are utilized to detect relative full poses of adjacent hydraulic supports, detection signals of the multiple guyed displacement sensors are processed in real time, the complex pose information is converted into the simple pose matrix information, information transmission volume is substantially reduced, the time of the top board pose matrix information and the foundation pose matrix information of each hydraulic support for respectively occupying pose signal transmission cables is shortened, performance demands of information transmission of hundreds of working face working face hydraulic supports in a pose detection process for transmission equipment are reduced, the waiting time in the information transmission process is shortened, remote transmission capability of the pose matrix information is improved, and remote pose monitoring on the hydraulic supports is realized.

Description

technical field [0001] The invention relates to a hydraulic support posture and straightness detection system and a working method thereof, belonging to the technical field of hydraulic support posture detection. Background technique [0002] The hydraulic support is a structure used to control the mine pressure of the coal mining face. Mining face mine pressure acts on the hydraulic support in the form of external load. In the mechanical system of the interaction between the hydraulic support and the surrounding rock of the mining face, if the resultant force of the supports of the hydraulic support and the resultant force of the external load acting on the hydraulic support by the roof are exactly on the same line, the hydraulic support is very suitable for the surrounding rock of the mining face . [0003] With the development of coal mining technology, the requirements for the stability and safety of the hydraulic support of the working face are getting higher and high...
