Embodiment 1

[0054] Such as figure 1 As shown, the present embodiment provides a hydraulic support automatic straightening system and a scraper conveyor follower straightening system, including a camera ranging device 1, a controller 2, a first marker 3 and a second marker 4; The marker 3 is arranged on the scraper conveyor 5, the camera distance measuring device 1, the controller 2 and the second marker 4 are arranged on the hydraulic support, the camera distance measuring device 1 and the controller 2 are installed on the rotating mechanism, and by rotating The mechanism realizes the rotation of the camera ranging device 1;

[0055] The camera distance measuring device comprises a camera 11, an infrared distance sensor 9 and an illuminating lamp 10, and the camera 11, the infrared distance sensor 9, the illuminating lamp 10 and the controller 2 are successively installed on the rotating mechanism from top to bottom, wherein the camera 11 and the infrared distance The sensors 9 are all c...

Embodiment 2

[0066] An automatic straightening system of a hydraulic support and a follower straightening system of a scraper conveyor, the structure of which is as described in Embodiment 1, the difference is that the pedestal 14 is fixedly installed on the hydraulic support through the mounting base 16, as Figure 7 shown. For different types of hydraulic supports, when the pedestal cannot be directly installed in the center of the hydraulic support, the mounting base can be used to straddle the hydraulic support.

Embodiment 3

[0068] The working method of a hydraulic support automatic straightening system and a scraper conveyor follower straightening system as described in Embodiment 1 comprises the following steps:

[0069] Hydraulic support automatic straightening working process:

[0070] 1) The distance from the first hydraulic support to the facing coal wall is measured by the infrared distance sensor, and the measurement result is transmitted to the controller of the frame. The controller calculates the distance that the hydraulic support should move according to the position of the infrared distance sensor. At the same time, this moving distance is transmitted to the controllers of other hydraulic supports;

[0071] 2) Before starting to move the frame, the camera on each hydraulic support shoots the second marker on the adjacent hydraulic support behind, and saves the captured picture in the controller for subsequent comparison;

[0072] 3) After starting to move the frame, the controller o...

Abstract

The invention relates to an automatic straightening system of a hydraulic support, a straightening system for a scraper conveyor follower and an application thereof. The straightening system includes a camera distance measuring device, a controller, a first marker and a second marker; The device includes a camera, an infrared distance sensor and a lighting lamp; the image information of the first marker and / or the second marker is collected by the camera and transmitted to the controller, and the image information between the hydraulic support and the coal wall and the scraper conveying are collected by the infrared distance sensor. The distance between the scraper conveyor and the hydraulic support is transmitted to the controller, and the movement and straightening of the scraper conveyor and the hydraulic support are realized through the control of the controller. The present invention is based on the image feature extraction processing algorithm, uses the camera to take the image information of the first marker or the second marker, and can complete the straightening of the hydraulic support and the straightening of the follower of the scraper conveyor through the camera on the hydraulic support, and can realize Quickly move and straighten jobs.

Description

technical field [0001] The invention relates to an automatic straightening system of a hydraulic support, a follower straightening system of a scraper conveyor and an application thereof, belonging to the technical field of hydraulic supports. Background technique [0002] The "Coal Mine Safety Regulations" stipulates that during comprehensive mechanized coal mining, the coal wall of the working face, the scraper conveyor and the hydraulic support must be kept in a straight line. The hydraulic support and the scraper conveyor need to be aligned during the operation of the shearer. If the straightness of the scraper conveyor is poor, the straightness of the cut coal wall will be poor, and the alignment of the hydraulic support is the alignment of the scraper conveyor. Foundation. [0003] The current straightening method is mainly completed by manual operation or using a large number of sensors. For example, the Chinese patent document CN111442759A discloses a unified monit...
