Description

Technical Field

[0001] This utility model relates to the technical field of coal mine backfilling mining support equipment, specifically a backfilling scraper conveyor support device for backfilling mining supports. Background Technology

[0002] A filling support is a special hydraulic support used in filling mining faces to provide space for filling operations. Common types include pneumatic filling supports and water-sand filling supports. A filling scraper conveyor support device is a piece of equipment specifically designed for filling mining and is a component of the filling support system, used to support the scraper conveyor.

[0003] Chinese patent discloses a support device for a filling scraper conveyor in a filling mining support (authorization announcement number CN113586141 U). This patented technology solves the problem that the existing method of suspending the filling scraper conveyor in a filling mining support makes it easy for the filling scraper conveyor to twist during operation, making it difficult to carry out coal mining and filling operations in parallel. However, this patented technology does not have a device designed to keep the filling scraper conveyor horizontal or adjust it to other angles when the utility model is tilted. It also only has a hydraulic device for lifting and lowering in the support and lifting structure, so the stability of the support is questionable. Therefore, those skilled in the art provide a support device for a filling scraper conveyor in a filling mining support to solve the problems mentioned in the background art. Utility Model Content

[0009] As a further embodiment of this utility model: the telescopic support mechanism includes a thin screw, a medium threaded sleeve, a coarse threaded sleeve, an outer shell, a first medium shell, a second medium shell, and an inner shell. The outer shell is installed at the center of the inclined plate. An annular groove is provided at the bottom of the outer shell, and the thin screw is installed therein. The outer shell and the thin screw are rotatably connected. An annular groove is provided at the bottom of the first medium shell, and a medium threaded sleeve is installed therein.

Both ends of the first intermediate shell are provided with slide rails and slide grooves, respectively. The first intermediate shell is slidably connected to the outer shell, and one end of the outer shell is provided with a slide groove.

[0010] As a further embodiment of this utility model: an inclined rod is provided at the right end of the inclined plate, and a rod groove is provided in the middle of the inclined rod. A rotating shaft is provided at the left end of the inclined plate, and the rotating shaft is installed in a rotating shaft sleeve.

The inclined plate is slidably connected to the filling scraper conveyor through the T-shaped grooves. A hydraulic device II is provided at the right end of the inclined plate, and the left end of the hydraulic device II is installed at the right end of the filling scraper conveyor.

[0011] As a further embodiment of this utility model: two guide ports are symmetrically arranged at the left end of the filling platform, a curved plate is arranged at the right end of the filling platform, a hydraulic device is installed on the curved plate, the other end of the hydraulic device is installed in the rod groove, and a rotating shaft sleeve is arranged on the right side of the guide port.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The inclined plate used in this utility model allows the filling scraper conveyor to slide on the inclined plate and also allows the inclined plate to be tilted by the hydraulic device, thereby tilting the filling scraper conveyor. Thus, the angle of the filling scraper conveyor can always be adjusted to keep it horizontal. The sliding of the filling scraper conveyor on the inclined plate is achieved by the T-groove and the hydraulic device. The tilting of the filling scraper conveyor is achieved by the hydraulic device pushing the inclined plate to rotate around the rotating shaft sleeve.

[0014] 2. The synchronous rotation device used in this utility model enables multiple telescopic support mechanisms to rise synchronously with only one external force input. The synchronous rise of multiple telescopic support mechanisms can keep the filling platform and the base box parallel, and at the same time, there is no need to adjust multiple telescopic support mechanisms. This not only ensures the stability of this utility model, but also makes it more automated. By rotating the central shaft through an external motor or transmission shaft, the central gear can be rotated, and the three external gears meshing with the central gear will rotate accordingly. With the rotation of the external shaft in the external gear, the telescopic support mechanism is driven to rise and fall. Since all external gears have the same structure and the same direction of rotation, synchronous rotation can be achieved. Moreover, the three telescopic support mechanisms support the filling platform in a triangle, so the support stability is high.

[0015] 3. The telescopic support mechanism used in this utility model can adjust the height of the filling platform. It adopts a multi-stage threaded fit, which can adjust the height range. The central shaft is rotated by an external motor or transmission shaft, which in turn rotates the external gear, which in turn rotates the fine screw. Subsequently, the middle threaded sleeve, the coarse threaded sleeve, and the inner shell are driven step by step to rise or fall. The outer shell fixes the height of the fine screw. The sliding grooves on the outer shell, the sliding grooves on the first and second middle shells, and the sliding rails on the inner shell prevent the first middle shell, the second middle shell, the inner shell, and the outer shell from rotating relative to each other and can only slide to rise and fall. Furthermore, the slots on the first and second middle shells allow the rising and falling of the middle threaded sleeve and the coarse threaded sleeve to drive the first and second middle shells to rise and fall.

[0030] The working principle of this utility model:

[0031] The inclined plate 2 used in this utility model allows the filling scraper conveyor 4 to slide on the inclined plate 2, and the inclined plate 2 can be tilted by the hydraulic device 101, thereby tilting the filling scraper conveyor 4. Thus, the angle of the filling scraper conveyor 4 can always be adjusted to keep it horizontal. The sliding of the filling scraper conveyor 4 on the inclined plate 2 is achieved by the T-groove 203 and the hydraulic device 204. The tilting of the filling scraper conveyor 4 is achieved by the hydraulic device 101 pushing the inclined plate 2 to rotate around the rotating bushing 104.

[0032] The synchronous rotation device 6 used in this utility model enables multiple telescopic support mechanisms 3 to rise synchronously with only one external force input. The synchronous rise of multiple telescopic support mechanisms 3 can keep the filling platform 1 and the base box 5 parallel, and at the same time, there is no need to adjust multiple telescopic support mechanisms 3. This not only ensures the stability of this utility model, but also makes it more automated. By rotating the central shaft 601 through an external motor or transmission shaft, the central gear 604 can be rotated. The three external gears 603 meshing with the central gear 604 will rotate accordingly. As the external shaft 602 in the external gear 603 rotates, it drives the telescopic support mechanism 3 to rise and fall. Since all external gears 603 have the same structure and the same direction of rotation, they can achieve synchronous rotation. Moreover, the three telescopic support mechanisms 3 support the filling platform 1 in a triangular shape, so the support stability is high.

[0033] The telescopic support mechanism 3 used in this utility model can adjust the height of the filling platform 1. It adopts a multi-stage threaded engagement, which allows for a large adjustable height range. The central shaft 601 is rotated by an external motor or transmission shaft, which in turn rotates the external gear 603, causing the fine screw 301 to rotate. Subsequently, the intermediate threaded sleeve 302, the coarse threaded sleeve 303, and the inner shell 307 are raised or lowered in stages by the transmission. The outer shell 304 fixes the height of the fine screw 301. The sliding grooves on the outer shell 304, the sliding grooves and slide rails on the first and second intermediate shells 305 and 306, and the slide rails on the inner shell 307 prevent the first intermediate shell 305, the second intermediate shell 306, the inner shell 307, and the outer shell 304 from rotating relative to each other and can only slide to raise and lower. Furthermore, the slots on the first intermediate shell 305 and the second intermediate shell 306 allow the raising and lowering of the intermediate threaded sleeve 302 and the coarse threaded sleeve 303 to drive the raising and lowering of the first intermediate shell 305 and the second intermediate shell 306.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
