Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine roadway support detection, and specifically relates to a straightness detection device for an advanced hydraulic support during support movement. Background Technique

[0002] Affected by coal mining and tunneling projects, the roof and floor and the surrounding rock masses on both sides of the roadway are deformed and displaced into the roadway. With the development of coal mining technology, the requirements for the stability and safety of the hydraulic supports on the working face are getting higher and higher, and the requirements for the detection accuracy of the straightness of the hydraulic supports are also getting higher and higher.

[0003] A set of advanced hydraulic supports generally consists of two identical hydraulic supports on the left and right and the connecting hydraulic cylinders between the two hydraulic supports. During the support process, a set of advanced hydraulic supports can move forward simultaneously along the direction of the hydraulic supports, or the two hydraulic supports can be horizontally moved simultaneously through the expansion and contraction of the connecting hydraulic cylinders between the two hydraulic supports.

[0004] A hydraulic support is a structure for controlling the mine pressure on the coal mining working face. The mine pressure on the working face acts on the hydraulic support in the form of an external load. In the mechanical system of the interaction between the hydraulic support and the surrounding rock of the working face, if the resultant force of the supporting members of the hydraulic support is exactly in the same straight line as the resultant force of the external load acting on the hydraulic support by the roof, then the hydraulic support is very suitable for the surrounding rock of this working face. However, the existing detection devices need to be manually adjusted in real time during use, resulting in low detection efficiency. At the same time, the existing detection devices have poor stability during use. In view of this, the utility model designs a straightness detection device for an advanced hydraulic support during support movement to solve the above problems. Content of the Utility Model

Further, control the rear connecting oil cylinder 408 and the front connecting oil cylinder 409 to contract, so that the advanced hydraulic support at the right end starts to move. During the movement, the industrial camera 302 will continuously photograph the image of the hydraulic support, while the angle sensor 304 will real-time monitor the angle change of the advanced hydraulic support. By real-time monitoring the data of the industrial camera 302 and the angle sensor 304, the straightness of the advanced hydraulic support can be checked at any time, and adjustments can be made in time to ensure the stability and accuracy of the advanced hydraulic support during the movement process.According to the data provided by the industrial camera 302 and the angle sensor 304, feedback control is performed on the hydraulic system to adjust the moving speed and direction of the advanced hydraulic support, so as to maintain the straightness of the advanced hydraulic support during movement. When the hydraulic support moves to the target position, the hydraulic system is stopped, and the final position and angle information are recorded.

At this time, due to the action of the front connecting rod 203 and the rear connecting rod 204, the shield beam 202 can rotate, so that the top beam 201 can be kept stable. At the same time, since the left anti-toppling jack 405, the lower anti-toppling jack 406, and the right anti-toppling jack 407 can be telescopic, the distance between the front and rear two bases 205 can be changed. At this time, due to the action of the upper connecting oil cylinder 410, the left and right two groups of bases 205 can move synchronously, so as to ensure that the front and rear widths of the left and right two groups of support frames are the same, thereby improving the use range of the equipment. At the same time, it is convenient for the front and rear two bases 205 to move, so as to ensure the stability of the equipment. Further, control the rear searchlight 101 and the front searchlight 102 to work, so as to facilitate the work of the industrial camera 302. Further, when the advanced hydraulic support receives the command to move the support, the top protection support 301 and the bottom protection support 303 can make the industrial camera 302 and the angle sensor 304 move to the required positions by virtue of their own telescopic characteristics. Before the support moving starts, record the initial position and angle of the hydraulic support through the industrial camera 302 and the angle sensor 304, and set the parameters of the camera and the sensor according to the specific situation, including the exposure time, the light source intensity, the sampling rate, etc. Adjust the advanced hydraulic support to an appropriate angle to ensure that its surface can be completely photographed by the industrial camera 302, and the angle sensor 304 can accurately measure the angle of the advanced hydraulic support. Further, the control device controls the left rear column 401, the left front column 402, the right rear column 403, and the right front column 404 at the left end to reset. At this time, the controller controls the cooperation of the rear connecting oil cylinder 408 and the front connecting oil cylinder 409, so that the base 205 at the left end moves to the left, so that the advanced hydraulic support at the left end starts to move. Further, the controller controls the top beam 201 at the left end to be in close contact with the roadway top surface again, and at the same time resets the top beam 201 at the right end. Further, control the rear connecting oil cylinder 408 and the front connecting oil cylinder 409 to contract, so that the advanced hydraulic support at the right end starts to move. During the moving process, the industrial camera 302 will continuously take pictures of the hydraulic support, and the angle sensor 304 will real-time monitor the angle change of the advanced hydraulic support. By real-time monitoring the data of the industrial camera 302 and the angle sensor 304, the straightness of the advanced hydraulic support can be checked at any time and adjusted in time to ensure the stability and accuracy of the advanced hydraulic support during the moving process.According to the data provided by the industrial camera 302 and the angle sensor 304, feedback control is performed on the hydraulic system to adjust the moving speed and direction of the advanced hydraulic support so as to maintain the straightness of the advanced hydraulic support during movement. When the hydraulic support moves to the target position, the hydraulic system is stopped, and the final position and angle information are recorded. By using the industrial camera 302 and the angle sensor 304 for real-time monitoring and feedback control, it can be ensured that the hydraulic support maintains straightness during the support moving process, improving the accuracy and safety of support moving.
