Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mining technology, and in particular to a liftable guide pipe for grouting and reducing settling in coal mine overburden separation. Background Technology
[0002] The liftable feature of the guide pipe allows operators to adjust the grouting volume in real time according to the actual development of the delamination and the degree of grout filling. In areas with large delamination, the grouting volume can be increased, while in areas with small delamination or those that have been basically filled, the grouting volume can be reduced to avoid grout waste and optimize the grouting effect.
[0003] The existing liftable guide pipes used for grouting and reducing sedimentation in coal mine overburden delamination have a simple structure and lack a mixing device, resulting in uneven mixing of slurry components. The slurry may contain a large number of solid particles, which will adhere to the inner wall of the guide pipe when passing through it, easily affecting the capacity of the guide pipe and reducing the efficiency of grouting. In order to solve the aforementioned problems, a liftable guide pipe for grouting and reducing sedimentation in coal mine overburden delamination is provided. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a liftable guide pipe for grouting and reducing settling in coal mine overburden separation, comprising a guide pipe, a first connecting pipe and a second connecting pipe connected through the guide pipe, a circular block rotatably connected to the first and second connecting pipes, multiple sets of sliders connected to both ends of the circular block, an internal gear fixedly connected to the inner wall of the circular block, three sets of gears meshing with the internal gear, a motor connected to the top of one set of gears, a motor fixing frame provided at the top of the motor, the top of the motor fixing frame fixedly connected to the inner top of the first connecting pipe, multiple sets of vertical plates fixedly connected to the outer periphery of the circular block, and a stirring plate fixedly connected to the bottom of the multiple sets of vertical plates.
[0005] As an improvement to the above technical solution, both the surface of the first connecting pipe and the second connecting pipe are provided with sliding grooves, and multiple sets of sliders slide inside the sliding grooves.
[0006] As an improvement to the above technical solution, the bottom ends of the three sets of gears are fixedly connected to connecting rods, the bottom ends of the connecting rods are rotatably connected to limit blocks, and the bottom ends of the limit blocks are fixedly connected to the inner bottom end of the second connecting tube.
[0007] As an improvement to the above technical solution, an electric rotary table is provided on one side of the top end of the first connecting pipe. A winding wheel is fixedly connected to the top end of the electric rotary table. A rope is provided on the outside of the winding wheel. A scraper is fixedly connected to one end of the rope. The scraper slides on the inner wall of the guide tube.
[0008] As an improvement to the above technical solution, a limiting tube is provided on the periphery of the rope, and the limiting tube is fixedly connected to one side of the outer wall of the guide tube.
[0009] The beneficial effects of this utility model are as follows: by using a motor to drive the gear to rotate, the gear can simultaneously drive the internal gear to rotate. The rotation of the internal gear allows the circular block to rotate on the surface of the first connecting pipe and the second connecting pipe, thereby driving the stirring plate to rotate and stirring the slurry. This makes the components of the slurry more evenly mixed, preventing the slurry from having too many solid particles that adhere to the inner wall of the conduit and affect the capacity of the conduit, thus reducing the efficiency of grouting.

Detailed Implementation
[0015] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0016] See appendix Figure 1-4As shown, to solve the above problems, a liftable guide pipe for grouting and reducing sedimentation of overburden separation in coal mines is provided, including a guide pipe 1. The guide pipe 1 is connected to a first connecting pipe 2 and a second connecting pipe 4. The first connecting pipe 2 and the second connecting pipe 4 are rotatably connected to a circular block 3. Multiple sets of sliders 33 are connected to both ends of the side of the circular block 3. An internal gear 34 is fixedly connected to the inner wall of the circular block 3. The internal gear 34 is meshed with three sets of gears 37. The top of one set of gears 37 is connected to a motor 36. The top of the motor 36 is provided with a motor fixing frame 35. The top of the motor fixing frame 35 is fixedly connected to the inner top of the first connecting pipe 2. Multiple sets of vertical plates 32 are fixedly connected to the outer periphery of the circular block 3. A stirring plate 31 is fixedly connected to the bottom of the multiple sets of vertical plates 32.
[0017] The slurry can be transported to a preset position using the conduit 1. Then, with the help of the first connecting pipe 2 and the second connecting pipe 4, the conduit 1 is installed more securely and facilitates the connection of subsequent equipment. The motor 36 provides rotational power to the gear 37. During the rotation of the gear 37, the internal gear 34 can be driven to rotate on the surface of the first connecting pipe 2 and the second connecting pipe 4. Through the transmission of the internal gear 34, the circular block 3 rotates, which in turn drives the stirring plate 31 to stir the flowing slurry. The stirring allows the solid particles in the slurry to be fully dispersed, enhancing the fluidity and stability of the slurry, preventing blockage of the conduit 1, and making the slurry components more evenly mixed. It also prevents solid particles from adhering to the inner wall of the conduit 1, affecting the capacity of the conduit 1 and reducing the efficiency of grouting. The vertical plate 32 can be used to fix the stirring plate 31 to prevent it from falling off during long-term use and affecting the subsequent use effect.
[0018] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, the surfaces of the first connecting pipe 2 and the second connecting pipe 4 are both provided with grooves 5, and multiple sets of sliders 33 slide inside the grooves 5.
[0019] With the cooperation of slider 33 and groove 5, the circular block 3 rotates more stably on the surfaces of the first connecting pipe 2 and the second connecting pipe 4.
[0020] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, the bottom of the three sets of gears 37 is fixedly connected to a connecting rod 371, the bottom of the connecting rod 371 is rotatably connected to a limit block 372, and the bottom of the limit block 372 is fixedly connected to the bottom of the inside of the second connecting pipe 4.
[0021] By using the limit block 372 and connecting rod 371, friction between gear 37 and the outer wall of guide tube 1 or other components can be reduced, thus reducing the wear rate and extending the service life of the entire device.
[0022] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, an electric rotary table 63 is provided on one side of the top end of the first connecting pipe 2. A winding wheel 62 is fixedly connected to the top end of the electric rotary table 63. A rope 64 is provided on the outside of the winding wheel 62. A scraper 6 is fixedly connected to one end of the rope 64. The scraper 6 slides on the inner wall of the guide tube 1.
[0023] By using an electric rotary table 63, the winding wheel 62 can be driven to rotate. During the winding process, the rope 64 can be driven to move up and down on one side of the outer wall of the guide tube 1, so that the scraper 6 slides along the inner wall of the guide tube 1, effectively removing the deposits on the inner wall, ensuring that the inside of the guide tube 1 is clean and unobstructed, ensuring smooth flow of grout, improving grouting efficiency, and by regularly cleaning the inner wall of the guide tube 1, the stable operation of the entire grouting system is ensured, reducing failures caused by blockage of the guide tube 1 or other problems, and improving the reliability and safety of the system.
[0024] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a limiting tube 61 is provided around the periphery of the rope 64, and the limiting tube 61 is fixedly connected to one side of the outer wall of the conduit 1.
[0025] By using the limiting tube 61, a stable guiding channel can be provided for the rope 64, ensuring that it always maintains a straight line during up and down movement, avoiding deviation and entanglement, and improving the reliability of the system.
