Description

Technical Field

[0001] This invention relates to the field of conveyor belt equipment, and in particular to a conveyor belt longitudinal beam pipe inlet and outlet drainage device. Background Technology

[0002] In coal mines, water accumulates in the material transport roadways during tunneling and mining, and needs to be drained. The traditional method is to lay a dedicated drainage pipeline that extends as the tunneling roadway advances and shortens as the mining face retreats. Laying this drainage pipeline is time-consuming, labor-intensive, and wasteful of materials. Moreover, troubleshooting blockages in the dedicated drainage pipeline is quite complicated. Summary of the Invention

[0003] To address the problems of time-consuming, labor-intensive, and material-wasting dedicated drainage management during tunneling and mining processes, and the cumbersome troubleshooting of blocked drainage pipes, this invention proposes a conveyor belt longitudinal beam pipe drainage device.

[0004] The technical solution of this invention is implemented as follows: A conveyor belt longitudinal beam tube inlet and outlet drainage device is provided. The longitudinal beam tube of the H-tube support of the conveyor belt has a groove on the top. The groove is provided with slots at intervals on both sides. A pair of positioning clips are provided on the outer periphery of both ends of each longitudinal beam tube. Adjacent longitudinal beam tubes are connected by connecting sleeves. A roller adjusting pad assembly is provided above the middle of each longitudinal beam tube, and an inlet and outlet drainage assembly is provided below the middle of the longitudinal beam tube. Both the first and last longitudinal beam sections of the conveyor belt are equipped with plug assemblies, and all the longitudinal beam sections are connected to form inlet and outlet pipes; the positioning clips at both ends of each longitudinal beam section are inserted into the slots and rotated to limit their movement, and lock the adjacent longitudinal beam sections and the connecting sleeves connecting the two longitudinal beam sections.

[0005] Preferably, the connecting sleeve is configured as a tapered ring sleeve that is thicker in the middle and thinner at both ends, with a positioning flange on the outer side of the middle part of the tapered ring sleeve; sealing gaskets are provided on both sides of the positioning flange.

[0006] Preferably, the idler roller adjusting pad assembly includes a positioning screw, a locking nut, and an adjusting flat washer, with the adjusting flat washer fitted onto the positioning screw and the locking nut connected to the positioning screw.

[0007] Preferably, the side of the positioning card is provided with a threaded thread, and an adjusting screw is provided inside the threaded thread. The adjusting screw is connected to the clamping sleeve of the H-tube bracket of the conveyor belt.

[0008] Preferably, the inlet and outlet assembly includes inlet and outlet pipes, with a water control valve installed at the inlet and outlet pipe openings, and a drain pump connected to the inlet.

[0009] Preferably, the plug assembly includes a conical plug, and a pair of positioning protrusions are provided on the outer side of the conical plug for engaging with the slots on the groove to limit the movement and press the conical plug tightly.

[0010] The beneficial effects of this invention are as follows: The conveyor belt longitudinal beam pipe inlet and drainage device of this invention utilizes the longitudinal beam pipe of the conveyor belt for water inlet and drainage, avoiding dedicated inlet and drainage pipes, achieving multiple uses with a single pipe, and saving energy and increasing efficiency; each section of the longitudinal beam pipe is equipped with an inlet and drainage assembly, and the location of the blockage can be confirmed by checking the inlet and drainage assembly when blocked, and the replacement of the longitudinal beam pipe is simple and quick, simplifying troubleshooting and quickly eliminating faults; the two sets of longitudinal beam pipes under the H-pipe support can form two sets of inlet and drainage pipes, improving utilization efficiency, and can also be used as static pressure water pipelines. The conveyor belt longitudinal beam pipe inlet and drainage device of this invention does not require special installation, and can be installed by tunneling workers during entry and retrieved by fully mechanized mining workers during retrieval, saving manpower and resources, and is very convenient to install and disassemble.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Example: Figures 1 to 3 The conveyor belt longitudinal beam pipe inlet and outlet drainage device shown has a groove on the upper part of the longitudinal beam pipe of the H-pipe support of the conveyor belt. The groove is provided with slots at intervals on both sides. Each longitudinal beam pipe 1 has a pair of positioning clips 2 on the outer periphery of both ends. A connecting sleeve 3 is provided between two adjacent drainage pipes. A roller adjusting pad assembly 4 is provided above the middle of each longitudinal beam pipe 1. A drainage inlet and outlet assembly 5 is provided below the middle of each longitudinal beam pipe. Both the first and last longitudinal beam pipes are provided with plug assemblies. All longitudinal beam pipes are connected to form a drainage inlet and outlet pipe. The positioning clips at both ends of each longitudinal beam pipe are inserted into the slots and rotated to limit their movement, locking the adjacent longitudinal beam pipes and the connecting sleeve 3 connecting the two longitudinal beam pipes.

[0016] like Figure 2 As shown, the connecting sleeve 3 is a tapered ring with a thicker middle and thinner ends, and the outer side of the middle part of the tapered ring has a positioning flange 31; sealing gaskets are provided on both sides of the positioning flange to seal the longitudinal beam tube and the connecting sleeve.

[0017] like Figure 1 As shown, the idler roller adjusting pad assembly 4 includes a positioning screw 41, a locking nut 42, and an adjusting washer 43. The adjusting washer 43 is fitted onto the positioning screw, and the locking nut 42 is connected to the positioning screw 41. The idler roller adjusting pad assembly is used to limit the upper and lower positions of the longitudinal beam tube.

[0018] like Figure 3 As shown, the side of the positioning card 2 is provided with a threaded thread 21, and an adjusting screw 22 is provided inside the threaded thread. The adjusting screw is connected to the H-tube clamping sleeve 23 of the conveyor belt to enhance the stability of the connection.

[0019] like Figure 1 As shown, the water inlet and drainage assembly includes water inlet and drainage pipes, and water control valves are installed at the inlet and drainage pipe openings to control water inlet and drainage.

[0020] In coal mine material transport roadways, water accumulates during tunneling and mining, requiring drainage. This water can be easily discharged through the longitudinal beam pipes of the conveyor belt. Static pressure water on the surface can also be transported to the working face via these longitudinal beam pipes, eliminating the need for two dedicated inlet and outlet pipelines. A drainage pump is used, connecting its outlet to the inlet of the inlet and outlet assembly.

[0021] When there is water in the roadway water storage tank, start the drainage pump to draw water through the water control valve of the inlet and outlet assembly into the longitudinal beam pipe and output to the centralized water tank. Wait for the water in the roadway water storage tank to be discharged, then turn off the drainage pump. The drainage cycle of the conveyor belt longitudinal beam pipe inlet and outlet device is completed.

[0022] The conveyor belt longitudinal beam pipe inlet and outlet drainage device of this invention can directly replace traditional specialized pipelines in coal mines. It only requires improvements to the existing conveyor belt H-pipe support. The original longitudinal beam pipe is directly processed into a longitudinal beam pipe with positioning clips, idler roller adjusting pad assemblies, and inlet and outlet drainage assemblies. Adjacent longitudinal beam pipes are connected by a connecting sleeve. No welding or other fixing methods are needed for connection. The positioning clips of the longitudinal beam pipes are inserted into the slots and rotated. The positioning clips lock into the slots and simultaneously limit their movement. The two adjacent longitudinal beam pipes, in turn, compress and seal the connecting sleeve, creating a tight connection. This connection method is simple to install and easy to disassemble, facilitating installation and maintenance. It is safe and practical for use in the complex underground environment. The connection method between the plug assembly and the longitudinal beam pipe is the same.

[0023] The conveyor belt's H-tube support has two rows of longitudinal beam pipes, forming two sets of inlet and outlet pipes. When one inlet / outlet pipe is blocked, it does not affect the other. Furthermore, repairing the blocked pipe does not affect drainage underground, nor does it affect the inlet / outlet pipes' function as static pressure water pipelines. This invention's conveyor belt longitudinal beam pipe inlet / outlet device is a direct improvement on the conveyor belt's H-tube support, saving both materials and manpower. The device is installed directly during H-tube support installation and disassembled directly when the H-tube support is removed.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
