Description

A spray dust removal device for coal mining and tunneling Technical Field

[0001] This utility model belongs to the field of spray dust removal technology, and in particular relates to a spray dust removal device for coal mining and tunneling. Background Technology

[0002] Currently, during coal mining using tunneling machines, a large amount of dust is generated at the mining site. Therefore, existing tunneling machines are usually equipped with dust suppression spraying devices. To ensure the spraying area, spraying mechanisms are sometimes installed around the entire tunneling machine. However, in actual use, multiple spraying mechanisms in the dust suppression system sometimes share a single power pump. This means that when one spraying mechanism is damaged and needs repair, all spraying mechanisms must be shut down simultaneously. Furthermore, when it is necessary to replace one of the spraying mechanisms, it is not convenient to disassemble and install the spraying mechanism on the tunneling machine, resulting in many inconveniences during use. Therefore, the existing technology still has shortcomings and deficiencies. Summary of the Invention

[0003] The purpose of this invention is to provide a spray dust removal device for coal mining and tunneling, so as to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A dust suppression spraying device for coal mining includes a base on which vertically distributed water tanks are mounted. A support plate coaxially aligned with the water tanks is mounted on the top surface of the water tanks. A support column is coaxially mounted on the support plate. Several support rods are equidistantly distributed along the circumference of the support column and parallel to its radial direction. A bearing ring detachably mounted on the support plate is also slidably fitted on the support column. The bearing ring includes several bearing plates, equal in number to the support rods, which are detachably and fixedly connected end-to-end. Each bearing plate is hinged with an upwardly inclined diverter plate. The diverter plates are detachably connected to the support rods, and several spray nozzles are connected to the side of the diverter plate away from the support column. Each diverter plate is also detachably connected to a water pump mounted on the water tank, and the water pumps are all connected to the inside of the water tank.

[0006] Furthermore, each bearing plate has a first connecting block and a second connecting block fixedly installed at both ends, and the first connecting blocks on two adjacent bearing plates are located above the second connecting blocks and connected by countersunk bolts.

[0007] Furthermore, a groove adapted to the outer diameter of the bearing ring is coaxially formed on the top surface of the support plate.

[0008] Furthermore, each of the support rods is equipped with a U-shaped hinge seat with a U-shaped opening facing the diverter plate at the end away from the support column. A pin is installed on the U-shaped hinge seat, and a cotter pin is installed after the pin passes through the U-shaped hinge seat. Each of the diverter plates is fixedly installed with a support on the side close to the support column. The support is respectively sleeved on the pin located in the U-shaped hinge seat and slidably connected to the pin.

[0009] Furthermore, each diversion plate is fixedly connected to a first connecting pipe on the side near the support column. The water pump and the diversion plate are respectively connected by a water delivery hose. The end of the water delivery hose away from the water pump passes through the support plate and the bearing ring in sequence and is fixedly connected to a second connecting pipe. The second connecting pipe and the first connecting pipe are together sleeved and threadedly connected to a third connecting pipe. The length of the third connecting pipe is less than the length of the second connecting pipe.

[0010] Furthermore, the top of the water tank is connected to a water inlet pipe.

[0011] The beneficial effects of this utility model by adopting the above technical solution are as follows:

[0012] This invention forms a spraying mechanism by setting up a support plate, a distribution plate, and spray nozzles. Since each distribution plate is connected to a water pump, each spraying mechanism is equipped with a water pump. Therefore, when one spraying mechanism is damaged and needs repair, only the corresponding water pump needs to be turned off, and the other spraying mechanisms can continue to perform spraying and dust removal operations normally. Secondly, since the support ring and the support plate are detachably connected, and every two adjacent support plates are detachably fixed, and the distribution plate, support rod, and water pump are also detachably connected, it is easy to disassemble and install the spraying mechanism on the coal mining machine when one spraying mechanism needs to be replaced. Moreover, the disassembly and installation of the spraying mechanism to be replaced does not affect the normal operation of the other spraying mechanisms, thus making it convenient to use.

[0020] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] As shown in Figures 1 to 6, this utility model provides a spray dust removal device for coal mining and tunneling, including a base 4, on which vertically distributed water tanks 5 are installed. Specifically, in use, the base 4 can be installed on the coal mining and tunneling machine using bolts or welding to fix the position of the water tanks 5. A support plate 3 is mounted on the top surface of the water tank 5, coaxially arranged with the water tank 5. A support column 1 is coaxially installed on the support plate 3. Several support rods 6 are installed on the top of the support column 1, equidistantly distributed along the circumference of the support column 1 and parallel to the radial direction of the support column 1. A bearing ring 2 is also slidably mounted on the support column 1 and detachably installed on the support plate 3, that is, the bearing ring 2 and the support plate 3 are detachably connected. The bearing ring 2 includes several bearing plates 21, the same number as the support rods 6, which are detachably fixedly connected end to end. The adjacent support plates 21 are detachably fixedly connected; each support plate 21 is hinged with an upwardly distributed diverter plate 7, which is a shell structure with a cavity; the diverter plate 7 is detachably connected to the support rod 6, and the side of the diverter plate 7 away from the support column 1 is connected to several spray nozzles 8, which are nozzles that can spray water mist outward in the prior art; each diverter plate 7 is also detachably connected to a water pump 9 installed on the water tank 5, and multiple water pumps 9 can share a power supply, and each water pump 9 is externally connected to a start / stop switch, which can control the start and stop of each water pump 9; the water pumps 9 are all connected to the inside of the water tank 5, specifically, the water pumps 9 are connected to the inside of the water tank 5 through a water supply pipe 10, and the end of the water supply pipe 10 away from the water pump 9 is located at the bottom of the water tank 5, and a connecting rod 11 is fixed between the water supply pipe 10 and the inner wall of the water tank 5.

[0022] Specifically, a spraying mechanism can be formed by setting up a bearing plate 21, a diverter plate 7, and a spray nozzle 8. Since each diverter plate 7 is connected to a water pump 9, each spraying mechanism is equipped with a water pump 9. Therefore, when one spraying mechanism is damaged and needs maintenance, only the corresponding water pump 9 needs to be turned off, and the other spraying mechanisms can continue to perform spraying and dust removal operations normally. Secondly, since the bearing ring 2 and the support plate 3 are detachably connected, and every two adjacent bearing plates 21 are detachably fixed, and the diverter plate 7 is also detachably connected to the support rod 6 and the water pump 9, it is easy to disassemble and install the spraying mechanism on the coal mining machine when it is necessary to replace one of the spraying mechanisms. Moreover, the disassembly and installation of the spraying mechanism to be replaced will not affect the normal operation of the other spraying mechanisms, thus making it convenient to use.

[0023] The specific arrangement of several bearing plates 21 that can be detachably and fixedly connected end to end is as follows: As shown in Figures 4 and 5, each bearing plate 21 has a first connecting block 22 and a second connecting block 23 fixedly installed at both ends. The first connecting blocks 22 on two adjacent bearing plates 21 are located above the second connecting blocks 23 and are connected by countersunk bolts 24. Specifically, a countersunk hole is opened on the top surface of the first connecting block 22. When two adjacent bearing plates 21 are connected, the screw end of the countersunk bolt 24 is threaded to the second connecting block 23 after passing through the first connecting block 22. The head of the countersunk bolt 24 is located in the countersunk hole opened on the first connecting block 22. This facilitates the assembly and disassembly of two adjacent bearing plates 21.

[0024] The specific arrangement of the detachable bearing ring 2 on the support plate 3 is as follows: As shown in Figures 1 and 4, a groove 31 that matches the outer diameter of the bearing ring 2 is coaxially opened on the top surface of the support plate 3. Specifically, during use, when the bearing ring 2 is installed on the support plate 3, after several bearing plates 21 are assembled into the bearing ring 2, the bottom of the bearing ring 2 can be located in the groove 31 to limit the radial position of the bearing ring 2. This makes it easier to connect the diverter plate 7 to the support rod 6 by rotating the diverter plate 7. In addition, the horizontal distance between the end of the support rod 6 away from the support column 1 and the center line of the support column 1 is much smaller than half the inner diameter of the bearing ring 2. Thus, after the diverter plate 7 of multiple spraying mechanisms is disassembled from the support rod 6 and the water pump 9 respectively, and the diverter plate 7 is turned outward, multiple spraying mechanisms can be removed simultaneously in the vertical direction for easy use.

[0025] The specific arrangement of the detachable connection between the diverter plate 7 and the support rod 6 is as follows: As shown in Figures 1 and 5, a U-shaped hinge seat 12 with a U-shaped opening facing the diverter plate 7 is installed on the end of the support rod 6 away from the support column 1. A pin 13 is installed on the U-shaped hinge seat 12, and a cotter pin 14 is installed after the pin 13 passes through the U-shaped hinge seat 12. A support 15 is fixedly installed on the side of the diverter plate 7 near the support column 1. The support 15 is respectively sleeved on the pin 13 located in the U-shaped hinge seat 12 and slidably connected to the pin 13. Specifically, in use, when the cotter pin 14 is removed from the pin 13... Then, the pin 13 can be removed, and the distributor plate 7 can be rotated until the support 15 is away from the U-shaped hinge seat 12, so that the distributor plate 7 and the support rod 6 can be separated. By rotating the distributor plate 7 in the opposite direction until the support 15 is located inside the U-shaped hinge seat 12, the pin 13 and the cotter pin 14 can be installed in sequence to connect the distributor plate 7 and the support rod 6. This makes it easy to disassemble and assemble the distributor plate 7 and the support rod 6. In addition, the hinge position between the distributor plate 7 and the bearing ring 2 can also adopt the connection method of the distributor plate 7 and the support rod 6, so as to facilitate the disassembly and assembly of the distributor plate 7 between the bearing ring 2 and the support rod 6.

[0026] The specific arrangement of the detachable connection between the diversion plate 7 and the water pump 9 is as follows: As shown in Figures 1 to 3, each diversion plate 7 has a first connecting pipe 16 fixedly connected to the side near the support column 1. The water pump 9 and the diversion plate 7 are connected by water supply hoses 17. The end of the water supply hose 17 away from the water pump 9 passes through the support plate 3 and the bearing ring 2 and is then fixedly connected to a second connecting pipe 18. The second connecting pipe 18 and the first connecting pipe 16 are together fitted with and threadedly connected to a third connecting pipe 19. The length of the third connecting pipe 19 is less than that of the second connecting pipe 16. Specifically, regarding the length of the connector 18, during use, by rotating the third connecting pipe 19 until it is completely positioned on the second connecting pipe 18, the water supply hose 17 and the diverter plate 7 can be separated. When connecting the water supply hose 17 and the diverter plate 7, the second connecting pipe 18 and the first connecting pipe 16 can be aligned first, and then by rotating the third connecting pipe 19 until both ends of the third connecting pipe 19 are positioned on the first connecting pipe 16 and the second connecting pipe 18 respectively, the water supply hose 17 and the diverter plate 7 can be connected.

[0027] Furthermore, as shown in Figure 1, the top of the water tank 5 is connected to a water inlet pipe 20. Specifically, the water inlet pipe 20 is a vertically distributed L-shaped pipe. By setting the water inlet pipe 20, water can be added to the water tank 5. In addition, a removable sealing plug can be installed at the end of the water inlet pipe 20 away from the water tank 5 to prevent dust and other particles from entering the water tank 5 through the water inlet pipe 20.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
