Abstract
Description
Technical Field
[0001] This utility model relates to the field of filling device technology, specifically a mining grouting filling device. Background Technology
[0002] The high-pressure grouting machine for cracks is a professional machine used for high-pressure chemical grouting of structures. It uses single-component chemical grouting materials, has ultra-high pressure, does not require an air pressure source, and allows for rapid construction.
[0003] Grouting filling devices are used when it is necessary to fill the mine shafts generated during mining development.
[0004] Existing grouting and filling devices involve drilling holes at the top of the mine shaft and then transporting the filler material into the shaft. However, when filling the mine shaft, the pipes that transport the filler material are usually located at the top of the shaft. When the grout falls from a height to the bottom of the shaft, air bubbles are generated, which can prevent the filler material from effectively supporting the shaft and thus pose a safety hazard.
[0005] Furthermore, in existing grouting and filling devices, the conveying pipes transport the filling material, which is then piled up in one location and left to settle and disperse naturally. Existing grouting and filling devices cannot adjust the direction of the conveying material as needed, resulting in time-consuming and labor-intensive work efficiency. Utility Model Content
[0006] The purpose of this invention is to provide a mining grouting and filling device to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mining grouting and filling device, comprising:
[0008] frame;
[0009] The bottom pipe is located inside the frame, and the height of the bottom pipe can be adjusted as needed;
[0010] The inner side of the frame is connected to one end of the positioning frame by fasteners. The inner side of the positioning frame is connected to both sides of the slide plate by sliding. The top of the slide plate is connected to the gear roller by a rotating shaft. The bottom pipe is provided on the inner side of the gear roller. The bottom pipe has a toothed groove. The gear roller meshes with the toothed groove. The bottom of the slide plate is connected to the connecting plate by welding. One side of the connecting plate is connected to the guide wheel by a rotating shaft. The bottom of the bottom pipe is connected to the positioning post by welding. A right-angle tube is provided below the positioning post. A filling pump is provided on one side of the bottom pipe. The filling pump is fastened to the frame. The frame is provided with a first cylinder.
[0011] Preferably, one end of the slide plate is connected to the output end of the first cylinder by a fastener, the first cylinder is connected to the frame by a fastener, and the slide plate is symmetrically distributed inside the frame.
[0012] Preferably, a top pipe is provided above the bottom pipe, and a threaded ring is connected to the bottom of the top pipe by welding, and the threaded ring is connected to the inner wall of the bottom pipe by threads.
[0013] Preferably, a first motor is provided on one side of the gear roller, the output shaft of the first motor is connected to the gear roller by fasteners, and the first motor is connected to the top of the slide plate by fasteners.
[0014] Preferably, the outer wall of the positioning post is connected to the inside of the sliding ring by rotation, and the end of the sliding ring away from the positioning post is connected to the right-angle tube by welding.
[0015] Preferably, the outer wall of the top of the right-angle tube is connected to the inner wall of the gear ring by fasteners, the top of the gear ring meshes with a drive gear, and a second motor is provided on one side of the drive gear.
[0016] Preferably, the output shaft of the second motor is connected to the drive gear via fasteners, the second motor is connected to the bottom pipe via fasteners, the tooth grooves are symmetrically distributed on the bottom pipe, a second cylinder is provided below the first cylinder, the output end of the second cylinder is fastened to a clamping plate, and the second cylinder is fastened to a frame.
[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0018] Firstly, this utility model, by setting up a bottom pipe and a gear roller, allows one end of the pipe to move to the bottom of the mine. When grouting is required, the bottom pipe is placed in the middle of the gear, the first cylinder is opened, and the first cylinder extends and retracts, driving the sliding plate to move. The sliding plate drives the gear roller and guide wheel to clamp the bottom pipe. Then, the top pipe is fixed to the top of the bottom pipe by a threaded ring. The first motor is turned on, and the first motor drives the gear roller to rotate through the output shaft. The gear roller drives the bottom pipe and the top pipe downward through the tooth groove on the bottom pipe. When the top of the top pipe moves to the gear roller, an extended pipe is installed on the top of the top pipe until the bottom of the bottom pipe moves to the bottom of the mine. Grouting can then be carried out directly at the bottom of the mine, effectively preventing air bubbles from being generated when grouting at high altitudes. This ensures that the filling material can fully fill the interior of the mine, preventing safety hazards caused by incomplete filling material. This demonstrates the practicality of this device.
[0019] Secondly, by incorporating a right-angle tube and a gear ring, this invention allows for adjustment of the grouting material's position as needed. After grouting in one direction within the mine shaft for a certain period via the bottom right-angle tube, the second motor is activated. The second motor drives a drive gear via its output shaft, which in turn drives a sliding ring on a positioning column via the gear ring. The sliding ring then drives the right-angle tube to rotate until it reaches the other direction. This prevents the need to wait for the grouting material to settle and level naturally when grouting is only performed in one location within the mine shaft, effectively improving work efficiency.

The gear roller 8 drives the bottom pipe 4 and the top pipe 3 to move downward through the tooth groove 5 on the bottom pipe 4. When the top of the top pipe 3 moves to the gear roller 8, the extended pipe continues to be installed on the top of the top pipe 3 until the bottom of the bottom pipe 4 moves to the bottom of the mine. Grouting can then be carried out directly at the bottom of the mine, which effectively prevents air bubbles from being generated when grouting at high altitudes. This ensures that the filling material can be fully filled inside the mine, preventing safety hazards caused by insufficient filling material. This demonstrates the practicality of this device.
[0031] Specifically, one end of the slide plate 9 is connected to the output end of the first cylinder 6 via fasteners, the first cylinder 6 is connected to the frame 1 via fasteners, and the slide plate 9 is symmetrically distributed inside the frame 1.

Then, the top pipe 3 is fixed to the top of the bottom pipe 4 by the threaded ring 15. The first motor 14 is then opened, and its output shaft drives the gear roller 8 to rotate. The gear roller 8 moves the bottom pipe 4 and the top pipe 3 downwards through the toothed grooves 5 on the bottom pipe 4, until the top of the top pipe 3 moves to the gear. When at roller 8, continue to install the extended pipe on the top of the top pipe 3 until the bottom of the bottom pipe 4 moves to the bottom of the mine.
