Description

Technical Field

[0001] The present invention belongs to the technical field of gas drainage in coal mines, and relates to a pneumatically controlled hydraulic hose device and method for dredging and blocking underground drainage pipelines. Background Art

[0002] Existing automatic slag removal devices applicable to the negative pressure environment of underground gas drainage pipelines in coal mines need to be used in conjunction with a certain length of hydraulic hoses. The hydraulic hose reel is mainly used for winding, storing and transporting the hoses. In order to prevent damage to the hydraulic hose during winding, the winding diameter of the hydraulic hose reel is generally designed to be larger, which increases the volume of the hydraulic hose reel. Due to the excessive volume of the hydraulic hose reel, it is not convenient for winding the hydraulic hose. At the same time, the reel is generally installed on a bracket to facilitate winding of the hydraulic hose, but most brackets are not convenient for installation and disassembly of the reel, and the reel is not stable enough during the winding process of the hydraulic hose. When the existing hose reel is in use, the hose fixation is relatively complex, affecting the winding effect. At the same time, the hose cannot be fixed at any position when pulling out the hose, which is inconvenient to use. Moreover, the device occupies a large space, has a complex structure and is difficult to maintain, affecting the winding efficiency of the hydraulic hose. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a pneumatically controlled hydraulic hose device and method for dredging and blocking underground drainage pipelines to improve the winding and discharging efficiency of the hydraulic hose.

[0033] Embodiment

[0034] The pneumatic control device for collecting and discharging hydraulic hoses for unclogging underground drainage pipelines, as Figures 1 - 5 shown, includes a base 1, support frames 2 arranged on both sides of the base, and a reel 6, a wire arranging device 5, a first pneumatic pump 3 and a valve 4 located on the base. The reel 6 is provided with a pneumatic hose quick coupling 6-1 and a hydraulic hose quick coupling 6-2 to switch different media (wind and water) as needed. The valve 4 controls the rotation direction of the first pneumatic pump 3 to achieve forward and reverse rotation. The first pneumatic pump 3 drives the reel 6 to rotate through a drive chain 7, and the reel 6 drives the wire arranging device 5 through a driven chain 8 to achieve the winding of the hydraulic hose. The specific structure and functions are as follows:

[0035] Base 1: Support frames 2 are provided on both sides of the upper surface. A bearing 9 is provided at the middle position of the support frame 2 to achieve rotational connection with the reel 6. The bearing 9 is conducive to the stable rotation of the reel 6, and thus conducive to the reel 6 winding the hydraulic hose 10.

[0036] Reel 6: Adopts a hollow design, which can reduce the weight of the device without affecting its function.

[0037] Valve 4: A manual three-position four-way reversing valve, installed on the platform of the base 1, used to control the air inlet and outlet directions of the first pneumatic pump 3, and thus control the rotation direction of the reel 6.

[0038] First pneumatic pump 3: A small-power pneumatic pump, installed on the platform of the base 1, works by being driven by compressed gas, rotates according to the air inlet direction, and drives the reel 6 through a belt.

[0039] Wire arranging device 5: Installed on the support frame 2, it rotates synchronously with the reel 6 for wire arranging. It is a prior art, and its wire arranging principle is that the rotation of the polished rod transmits power to the bearing ring in contact with it. The frictional force between the bearing ring and the polished rod causes the bearing ring to move horizontally, thereby driving the wire arranging mechanism to move to the limit position and collide with the travel switch, thus changing the movement direction and realizing reciprocating wire arranging.

[0040] Pneumatic hose quick connector 6-1: Used to connect the air source and the pneumatic hose, located at one end of the reel of the reel 6.

[0041] Hydraulic hose quick connector 6-2: Used to connect the high-pressure water pipe 13 and the hydraulic hose 10, located at the other end of the reel of the reel 6.

[0042] The usage method of the hydraulic hose winding and unwinding device in this embodiment is as follows:

[0043] Connect the hydraulic hose quick connector 6-2 to the underground high-pressure water pipe 13, connect the hydraulic hose 10 to the hydraulic hose quick connector 6-2, the other end of the hydraulic hose 10 passes through the roller of the wire arranging device 5, install the jet nozzle 11, and the jet nozzle 11 enters the extraction pipeline through a tee. One end of the high-pressure water pipe 13 is connected to the hydraulic pump set 15, the hydraulic pump set 15 is connected to the second pneumatic pump 16, and the second pneumatic pump 16 is connected to the underground compressed air pipe 12 of the coal mine. Using the underground compressed air of the coal mine as power, the second pneumatic pump 16 drives the hydraulic pump set 15 to provide high-pressure water. The high-pressure water jet ejected by the jet nozzle 11 washes away the coal powder attached to the wall of the extraction pipeline 18 and transports it with water to the slag removal and drainage bucket 17; adjust the switch of the valve 4 to make the first pneumatic pump 3 rotate clockwise, drive the reel 6 to rotate clockwise through the drive chain 7 to start releasing the hydraulic hose 10, and the reel 6 drives the wire arranging device 5 through the driven chain 8 to reciprocate the wire by the wire arranging device 5, and release the hydraulic hose 10 evenly. After the hydraulic hose 10 on the reel 6 is released, turn on the second pneumatic pump 16 to fill the hydraulic hose 10 with water, and the jet nozzle 11 drives the hydraulic hose 10 to move forward in the extraction pipeline 18 to repeat the operation.

[0044] After the pipeline is dredged, turn off the hydraulic pump set 15, adjust the switch of the valve 4 to make the first pneumatic pump 3 rotate counterclockwise, drive the reel 6 to rotate counterclockwise through the drive chain 7 to start winding the hydraulic hose 10, and the reel 6 drives the wire arranging device 5 through the driven chain 8 to reciprocate the wire by the wire arranging device 5, and wind the hydraulic hose 10 evenly on the reel 6.

[0045] The present invention is mainly applied to the dredging and blocking of underground drainage pipelines. By reasonably combining the reel 6, the first pneumatic pump 3, the valve 4, and the wire arranging device 5, and using the underground compressed air as the power source, the reel 6 can conveniently and quickly wind and unwind the hose for dredging and blocking. Moreover, the structure is compact and lightweight, with a small volume, complete functions, easy operation, safety and reliability, and strong versatility. It can conveniently and quickly wind and unwind the hose for dredging and blocking, saving time and effort in operation, effectively saving working time, reducing the labor intensity of workers, and improving the construction quality and efficiency.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the present technical solution, and they should all be covered by the scope of the claims of the present invention.
