[0002] A filling support refers to a special hydraulic support that provides a filling operation space and is used in coal mining working faces using the filling method.

[0003] The traditional backfill mining end isolation support uses a hydraulic press to move straight up and down for support, but this method is not safe and cannot lock the support rod. If an accident occurs, it is easy to deform and collapse. Even if it is locked with bolts, first, the tool will be worn out. Second, the hydraulic press will maintain a large pressure, reducing its service life. Third, there are other equipment running on site, and the vibration generated by the operation of other equipment will easily loosen the bolts, which is very dangerous.

[0004] In order to solve the above problems, this application proposes a filling mining end isolation support. Utility Model Content

The top frame 22 is raised to support the object to be supported, and then the hand is supported on the screw sleeve. The sleeve 163 keeps the screw sleeve 163 from rotating, and then the motor 161 runs to drive the threaded rod 162 to rotate. The screw sleeve 163 is limited by hand, so that the threaded rod 162 drives the screw sleeve 163 to move leftward. The screw sleeve 163 fits tightly with the baffle 165.

The two sets of support mechanisms 1 can be operated synchronously to raise the top frame 22.

[0028] Working principle:

[0029] When the device is in use, after the base 3 is placed at the designated position, the top frame 22 is aligned with the position where the isolation support is required, the hydraulic rod 15 on the mounting frame 14 is operated to push the slider 13 to move leftward, the slider 13 pushes the rotating frame B236 to the left, the rotating frame B236 drives the rotating ring 234 at the bottom to move leftward, the rotating ring 234 at the bottom drives the rotating rod 235 to rotate clockwise along the rotating ring 234 at the top, and the rotating frame A233 and the rotating ring 234 are rotatably connected, so that the rotating frame A233 can be relatively The rotating ring 234 rotates, and the rotating rod 235 gradually pushes the bottom plate 232 to move upward vertically. The bottom plate 232 drives the bracket 231 upward, and the bracket 231 drives the top frame 22 upward. The telescopic rod 21 extends to follow the movement of the top frame 22. The telescopic rod 21 limits the top frame 22. The top frame 22 rises to support the object to be supported, and then the hand holds the screw sleeve 163 to keep the screw sleeve 163 from rotating. Then the motor 161 runs to drive the threaded rod 162 to rotate, and the hand limits the rotation of the screw sleeve 163. The threaded rod 162 drives the screw sleeve 163 to move left, and the screw sleeve 163 is tightly fitted with the baffle 165. Then, the limit plate 164 is slid left to the outside of the screw sleeve 163, and the surface of the outer wall of the screw sleeve 163 is fitted with the inner wall of the limit plate 164. The limit plate 164 limits the rotation of the screw sleeve 163. The motor 161 has a braking function. Because the motor 161 brakes and prevents the threaded rod 162 from rotating, the limit plate 164 limits the screw sleeve 163 from rotating arbitrarily on the threaded rod 162. Therefore, when the top frame 22 is supported for a long time and when other equipment vibrates during operation, the screw sleeve 163 remains tightly fitted with the baffle 165 and will not loosen, thereby preventing the slider 13 from moving, realizing the safety locking function, maintaining the position of the top frame 22, improving the stability of the device, and sharing part of the pressure on the hydraulic rod 15 to the screw sleeve 163, thereby extending the service life of the hydraulic rod 15. The two sets of support mechanisms 1 can be operated synchronously to raise the top frame 22.
