Description

Self-propelled advanced hydraulic support temporary support device Technical Field

[0001] This utility model belongs to the field of tunnel support technology, specifically a self-moving advanced hydraulic support temporary support device. Background Technology

[0002] A set of self-moving advanced hydraulic support temporary support devices consists of advanced hydraulic supports as the main component, with the advanced hydraulic supports connected end to end to form an advanced hydraulic support group. Each advanced hydraulic support is supplemented by a set of temporary support devices on both sides, and is arranged horizontally along the roadway. The extension and retraction of the connecting hydraulic cylinders between adjacent advanced hydraulic supports enables the adjacent hydraulic supports to be advanced and moved.

[0003] With the rapid development of mining and support technologies in my country, mining areas in the east are gradually moving towards deeper mining. As the mining depth increases, the frequency and intensity of rockbursts also increase significantly, which can easily lead to roadway deformation under pressure and the formation of some irregular roadway cross sections. For these roadways, the lack of temporary support during the relocation of advanced hydraulic supports can cause roof deformation, which poses certain safety risks.

[0004] However, most existing advanced hydraulic support systems have long and narrow top beams but small overall support area, and they use a single support method, which cannot adapt well to local undulations and bulges in the roadway roof. This can lead to localized high stress on the supported roadway roof, causing damage and affecting roadway roof management. Furthermore, existing support mechanisms lack temporary support, leading to roadway deformation under pressure, hindering the normal operation of the advanced hydraulic support, reducing the safety factor during operation, causing mining delays, failing to meet planned production, resulting in economic losses, and even threatening the lives of coal mine workers. To address these problems, this utility model designs a self-moving temporary support device for advanced hydraulic supports. Utility Model Content

[0027] When using this equipment, the operator places the entire device in a coal mine roadway.

Step 107 enables the front-end support beam 105 to complete its support, while simultaneously controlling the extension of the base connecting rod 203. This allows the base 106 to move while ensuring the temporary support base 301 remains stationary, thus guaranteeing the support effect. Further, after the front-end support beam 105 completes its support, the operator issues a command to retract the rear moving rod 101 and the front moving rod 102, causing the second base 106 to move to the position above the first base 106. The first temporary support hydraulic cylinder 307 is then reset, and the second support rod 107 is extended, allowing the second support beam 105 to support the original position of the first support beam 105. The base connecting rod 203 is then retracted, causing the first temporary support base 301 to move to a second position. Finally, the second temporary support base 301 moves back to the original position of the first temporary support base 301, thus enabling the entire equipment to move while maintaining the support effect.

[0028] The working process of this utility model is as follows: When using this equipment, the operator places the entire equipment in a coal mine roadway. The operator then controls the extension and retraction of multiple upper movable rods 103 via a controller, allowing the entire equipment to adapt to coal mine roadways of different widths. The operator then issues a command to extend multiple support rods 107, causing multiple support beams 105 to move upwards, thus achieving support. When the support beams 105 need to support the next position, the support rods 107 reset, and simultaneously, the temporary support hydraulic cylinder 307 extends, causing the temporary support roof plate 302 to be in close contact with the coal mine roadway. The operator further controls the extension of the main side plate movable rods 305 and the secondary side plate movable rods 306, thereby driving the main side plate 303 and the secondary side plate 304 to rotate, ensuring that the main side plate 303 and the secondary side plate 304 are in close contact with the roadway, thus guaranteeing the temporary support effect. Finally, the operator controls the extension of the rear movable rod 101 and the front movable rod 102, causing the front base 106 to move forward, further... The first step controls the support rod 107 to enable the front support beam 105 to complete the support. At the same time, the base connecting rod 203 is extended, so that the base 106 moves while the temporary support base 301 remains stationary, thus ensuring the support effect. Further, after the front support beam 105 completes the support, the operator issues a command to retract the rear moving rod 101 and the front moving rod 102, causing the second base 106 to move to the position above the first base 106. The first temporary support hydraulic cylinder 307 is then reset, and the second support rod 107 is extended, allowing the second support beam 105 to support the original position of the first support beam 105. The base connecting rod 203 is then retracted, causing the first temporary support base 301 to move to a second position, and then back to the original position of the first temporary support base 301. This achieves the movement of the entire equipment while ensuring the support effect.
