DETAILED DESCRIPTION

[0014] The present invention is described in detail below in conjunction with the accompanying drawings: like Figure 1 and 2 As shown, a vehicle for filling and plugging a plate wall for an underground mine goaf access road comprises a vehicle body 1, which can be an existing conventional engineering vehicle. A mechanical arm 2 is arranged on the vehicle body 1, and the mechanical arm 2 faces the front of the vehicle body. The mechanical arm 2 comprises a large arm 201 and a small arm 202. The mechanical arm 2 can be an existing conventional excavator. The large arm 201 is connected to the vehicle body 1, and a rotatable wall panel 3 is arranged at one end of the small arm 202. The wall panel 3 is of a rectangular structure, and the wall panel 3 is used for temporary plugging. Specifically, a mounting frame 4 is arranged at one end of the small arm 201 away from the large arm 201, and a rotating shaft 5 is arranged on the mounting frame 4. A sleeve is arranged on the rotating shaft 5 The sleeve 6 can rotate on the rotating shaft 5, and the wall panel 3 is installed on the sleeve 6. Specifically, a main connecting rod 7 is fixed on the sleeve 6 and is arranged perpendicular to the sleeve 6, that is, the connecting rod 7 can rotate in a vertical plane with the axis of the sleeve 6 as the center. The end of the main connecting rod 7 away from the sleeve 6 is fixed to the middle of the wall panel 3 and is arranged perpendicular to the wall panel 3. The wall panel 3 can rotate with the connecting rod 7. A hydraulic rod 8 is hinged at the middle of the arm 202. The hydraulic rod 8 and the arm 202 are located in the same vertical plane. The end of the hydraulic rod 8 away from the arm 202 is hinged to the wall panel 3. The main connecting rod 7 and the wall panel 3 can be driven to rotate by the extension and retraction of the hydraulic rod 8.

[0015] In order to make the connection between the sleeve 6 and the wall panel 3 more stable, a plurality of auxiliary support rods 9 are connected to the sleeve 6. Specifically, in this embodiment, four auxiliary support rods 9 are connected. One end of the auxiliary support rod 9 away from the sleeve 9 is connected to the edge of the wall panel 3. In this embodiment, the four auxiliary support rods 9 are respectively connected to the four edges of the wall panel 3.

[0016] The present invention is used in the following manner.

[0017] When it is necessary to seal the goaf, first move the vehicle body 1 to the position of the use area, then move the wall panel 3 to the corresponding position through the mechanical arm 2, and adjust the angle of the wall panel 3 through the extension and contraction of the hydraulic rod 8. The wall panel 3 can be moved quickly and flexibly by the mechanical arm 2, and can be accurately moved to the corresponding position, so that the wall panel 3 is at the corresponding position of the corresponding blocked hole. Then, a rainproof tarpaulin can be pasted on the side of the wall panel 3 away from the main connecting rod 7. The provision of the rainproof tarpaulin can facilitate the removal of the wall panel 3 after the filling is completed, and the gaps on the edges of the wall panel 3 on both sides can be closed. Foam rods are placed at the locations to seal the gaps, and concrete is placed and moved out. Then high-concentration cement mortar can be input into the goaf, and the interior of the goaf can be filled through a self-flowing filling process transported through pipelines. After the concrete solidifies, the vehicle body 1 can be moved to remove the wall panel 3 from the sealing position. After the use of this device is completed, the wall panel 3 can be moved to the top square of the vehicle body 1 by the mechanical arm 2, thereby facilitating the movement of the vehicle body 1. The use of this wall vehicle can quickly complete the sealing of the goaf. Compared with the traditional wall-building method, it is efficient and fast, and greatly saves manpower.
