The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0028] Referring to Figures 1 to 6 Figures 1 to 6 All features are shown for the purpose of illustration, and are not operational diagrams), the application provides a self-moving roadway hydraulic support, comprising: support body 100 and front moving assembly 200, the support body 100 comprises column 120, top beam 110, base 130 and support jack 140, both ends of the column 120 are connected with the top beam 110 and the base 130 respectively, the support jacks 140 are symmetrically arranged at both ends of the roadway trend of the base 130, the support jacks 140 can be telescopic up and down in the vertical direction, and the bottom of the support jack 140 is provided with a flat plate 141; the front moving assembly 200 comprises front push jack 210, front baffle 220 and bottom plate 230, the fixed end of the front push jack 210 is connected with one end of the base 130, the telescopic end of the front push jack 210 is connected with the front baffle 220, one end of the bottom plate 230 is connected vertically with one end of the front baffle 220, and the bottom plate 230 is attached to the lower surface of the base 130 away from the top beam 110.

[0029] Specifically, the top beam 110, column 120 and base 130 in the support body 100 can all use the common hydraulic support in the prior art, the support jacks 140 are connected by steel plates and other materials on both sides of the base 130, and two support jacks 140 are arranged on each side, and the flat plate 141 is arranged at the telescopic end of the support jack 140; the fixed end of the front push jack 210 extends into the front end of the base 130 and is fixed by means of a latch or a mounting barrel.

[0030] ​Furthermore, during the support operation, the self-propelled hydraulic support for the roadway is installed along the roadway direction (the line connecting the symmetrically arranged support jacks 140 on both sides is perpendicular to the roadway direction). The top beam 110 contacts the top of the roadway, and the base 130 contacts the bottom of the roadway. When the self-propelled hydraulic support moves, the column 120 retracts downward, causing the top beam 110 to move away from the top of the roadway. After the column 120 retracts to the preset position, the support jacks 140 extend downward and contact the bottom of the roadway, causing the base 130 to rise and become suspended. The extension of the support jacks 140 stops, and the forward-pushing jack 210 moves forward, driving the front baffle 220 and the base plate 230 to move. The forward-pushing jack 210 extends to its limit. After the stroke (the end of the base plate 230 away from the front baffle 220 does not extend beyond the base 130), the support jack 140 retracts upward to make the base 130 contact the ground, and then the rear support jack 320 extends downward and contacts the bottom of the roadway to complete the fixed support; at this time, using the front baffle 220 as the fulcrum, the forward push jack 210 retracts, pulling the base 130 to slide on the base plate 230 towards the end closer to the front baffle 220; after the current support jack 140 retracts to its original position, the support jack 140 extends to lift the base 130, the forward push jack 210 extends, and the rear push jack 310 retracts, and then the above steps are repeated until the self-propelled roadway hydraulic support reaches the designated position.

[0031] The technical solution of the self-moving hydraulic support for roadways adopted in this application can achieve the following beneficial effects:

[0032] 1. By deploying the forward-moving component 200 along the direction of the roadway, the problem of difficulty in rotating the support body 100 when deploying the forward-moving component 200 perpendicular to the direction of the roadway is solved.

[0033] 2. By using the forward-moving component 200 to pull the support body 100, the movement of the support body 100 becomes more convenient, and no other mechanical pulling is required, thereby solving the problem that it is difficult for transport machinery and equipment to enter and move the support in narrow alleys.

[0034] 3. By setting a base plate 230 at one end of the front baffle 220, and having the base plate 230 fit against the base 130, the problem of poor ground conditions at the bottom of the tunnel and difficulty in self-moving the support is solved.
