Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of mud pipe technology, and more specifically, to a mud pipe connection device for emergency drainage. Background Technology
[0002] In the event of a sudden water inrush or collapse during mining operations, the mine workers should be evacuated immediately. During this period, it is also necessary to carry out emergency drainage of the water in the mine by extending mud pipes into the waterlogged area and pumping them out with large water pumps. Before pumping out the water, the filter tank and mud pipes need to be connected, so a mud pipe connection device is required.
[0003] The existing connection device connects the flange on the mud pipe and the flange on the filter tank together. After the holes of the two sets of flanges are aligned, the two sets of flanges are fixed by bolts passing through the holes and nuts. However, the process of aligning the flange holes can take a lot of time for the operator, which affects the operator's subsequent work.
[0004] The aforementioned connection device has a drawback: it is difficult for operators to quickly locate the holes on the two sets of flanges, resulting in a significant amount of assembly time for the operators and thus reducing the effectiveness of the device. Utility Model Content
[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide an emergency drainage mud pipe connection device to solve the technical problem in the prior art where it is difficult for operators to quickly locate the holes on the two sets of flanges, resulting in a large amount of assembly time for operators.

[0009] In a preferred embodiment of the emergency drainage mud pipe connection device of this utility model, in order to better move the adjustment block, an adjustment rod is installed inside the connection groove, and the outer surface of the adjustment rod penetrates the interior of the adjustment block.
[0010] As a preferred embodiment of the emergency drainage mud pipe connection device of this utility model, in order to facilitate the operator to adjust the device, an adjustment frame is installed inside the adjustment block, and a positioning frame is sleeved on the outer surface of the adjustment frame.
[0011] As a preferred embodiment of the emergency drainage mud pipe connection device of this utility model, in order to facilitate the positioning of the flange hole position, positioning columns are installed on the inner sides of the two sets of positioning frames, and the outer surface of the positioning column passes through the positioning pipe located on the front side.
[0012] As a preferred embodiment of the emergency drainage mud pipe connection device of this utility model, in order for the positioning frames on the left and right sides to be in the same position after adjustment, a magnet is installed inside the positioning frame, and an adjusting pin is threaded through the front of the positioning frame.
[0013] In a preferred embodiment of the emergency drainage mud pipe connection device of this utility model, in order to facilitate the repositioning of the moving column, a protective pipe is installed inside the adjusting frame, a buffer rod is installed inside the adjusting frame, and a buffer spring is installed inside the adjusting frame.
[0014] In a preferred embodiment of the emergency drainage mud pipe connection device of this utility model, in order to improve the performance of the device, both the buffer spring and the buffer rod pass through the protective pipe, the outer surface of the buffer rod passes through the buffer spring and the movable column, and both the buffer spring and the buffer rod are disposed inside the fixed column.
[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] In this disclosure, by sliding the positioning piece into the first positioning frame through the mounting ring, the holes of the pipe body and the filter cartridge are fixed. Compared with the direct installation of the prior art, this device can quickly position the holes on the two sets of flanges, shortening the time required for operators to connect the two sets of flanges and improving the work efficiency of operators in assembling the device.
[0017] In this disclosure, by manipulating the moving column to move the adjusted filter cylinder to the left through the second positioning frame, the right end of the positioning tube is inserted into the filter cylinder.

[0030] like Figures 1-4 As shown, it illustrates an emergency drainage mud pipe connection device according to an embodiment of the present disclosure, which includes a pipe body 1 and a filter cylinder 2, and also includes a positioning pipe 3, a sealing gasket 4, a mounting ring 5, a positioning piece 6, a first positioning frame 7, a fixing column 8, an adjusting frame 9, a moving column 10, a second positioning frame 11 and a connecting plate 12.
[0031] like Figure 2As shown, the outer surface of the positioning tube 3 passes through the interior of the pipe body 1 and the filter cylinder 2. The inner sides of both the pipe body 1 and the filter cylinder 2 are in contact with the mounting ring 5 through flanges. After the flanges contact the mounting ring 5, the pipe body 1 and the filter cylinder 2 are fixed by external bolts and nuts. The external bolts need to pass through the positioning tube 3. A sealing gasket 4 is installed on the outer surface of the positioning tube 3. The sealing gasket 4 is a rubber product. The function of the sealing gasket 4 is to prevent leakage during the pumping process of the pipe body 1. The mounting ring 5 is installed on the outer surface of the sealing gasket 4. The positioning piece 6 is installed on the outer surface of the mounting ring 5. The outer side of the positioning piece 6 is slidably connected to the first positioning frame 7. The positioning piece 6 does not affect the pumping of the pipe body 1. A fixing column 8 is installed on the outer surface of the first positioning frame 7. An adjusting frame 9 is installed on the side of the fixing column 8. A moving column 10 is slidably connected inside the adjusting frame 9. A second positioning frame 11 is installed on the upper surface of the moving column 10. A connecting plate 12 is installed on the inner side of the two sets of second positioning frames 11.
[0032] like Figure 3 and Figure 4 As shown, both the first positioning frame 7 and the second positioning frame 11 have connecting grooves inside. An adjusting block 13 is slidably connected inside the connecting groove. An adjusting rod 14 is installed inside the connecting groove, and its outer surface penetrates the interior of the adjusting block 13. The center of the adjusting rod 14 is at the same position as the center of the first positioning frame 7. An adjusting bracket 15 is installed inside the adjusting block 13, and a positioning bracket 16 is fitted onto the outer surface of the adjusting bracket 15. Positioning pins 17 are installed on the inner sides of the two sets of positioning brackets 16. The outer surface of the positioning pins 17 passes through the positioning tube 3 located on the front side. A magnet 18 is installed inside the positioning bracket 16. An adjusting pin 19 is threaded through the front of the positioning bracket 16, and the adjusting pin 19 on the left side is threaded through... One end of the positioning frame 16 located on the left abuts against the first positioning frame 7, and the adjusting pin 19 located on the right threaded through the positioning frame 16 located on the right abuts against the second positioning frame 11. The adjusting pin 19 is used to fix the positioning frame 16 after adjustment. A protective tube 20 is installed inside the adjusting frame 9. A buffer rod 21 is installed inside the adjusting frame 9. A buffer spring 22 is installed inside the adjusting frame 9. Both the buffer spring 22 and the buffer rod 21 pass through the protective tube 20. The outer surface of the buffer rod 21 passes through the buffer spring 22 and the moving column 10. Both the buffer spring 22 and the buffer rod 21 are set inside the fixed column 8. A round hole is opened inside the fixed column 8, and the buffer spring 22 and the buffer rod 21 pass through the round hole.
[0033] It should be noted that this device can be used to connect the pipe body 1 and the filter cartridge 2, or to connect the pipe body 1 and the output end of an external water pump. In both cases, the positioning tube 3 is inserted into the hole of the flange for positioning and fixing.
[0034] In this embodiment, the installation ring 5 is manipulated to insert the left end of the positioning tube 3 into the flange on the pipe body 1. The installation ring 5 is manipulated to slide the positioning piece 6 into the first positioning frame 7, so that the flange on the pipe body 1 enters the first positioning frame 7. The positioning frame 16 on the left side is manipulated to flip upward, causing the adjustment frame 15 on the left side to flip upward. The adjustment frame 15 on the left side flips upward, causing the adjustment block 13 on the left side to flip upward. The adjustment block 13 on the left side flips upward along the adjustment rod 14 on the left side. The adjustment block 13 on the left side flips upward along the connecting groove on the left side. The positioning frame 16 on the left side flips upward, causing the magnet 18 on the left side to flip upward. The positioning frame 16 on the left side flips upward, causing the positioning post 17 on the left side to flip upward.
[0035] Manipulate the positioning frame 16 located on the left to move to the right along the adjustment frame 15 located on the left. The rightward movement of the positioning frame 16 on the left causes the positioning column 17 located on the left to move to the right. The positioning column 17 on the left moves to the right and inserts into the positioning tube 3 located on the front (e.g., Figure 1 As shown), after adjustment, insert the adjustment pin 19 located on the left into the positioning frame 16 located on the left, and then rotate the adjustment pin 19 located on the left clockwise to press against the first positioning frame 7.
[0036] In the initial state of the second positioning frame 11, the filter cartridge 2 is placed inside the second positioning frame 11. The positioning frame 16 on the right side is manipulated to flip upward, causing the adjustment frame 15 on the right side to flip upward. The adjustment frame 15 on the right side flips upward, causing the adjustment block 13 on the right side to flip upward. The adjustment block 13 on the right side flips upward along the adjustment rod 14 on the right side and flips upward along the connecting groove on the right side. The positioning frame 16 on the right side flips upward, causing the magnet 18 on the right side to flip upward. The positioning frame 16 on the right side flips upward, causing the positioning post 17 on the right side to flip upward. When the positioning post 17 on the right side flips to any hole on the flange of the filter cartridge 2, the positioning frame 16 on the right side is manipulated to move to the left along the adjustment frame 15 on the right side. The leftward movement of the positioning frame 16 on the right side causes the positioning post 17 on the right side to move to the left. The positioning post 17 on the right side moves to the left and inserts into the corresponding hole. The positioning frame 16 on the right side is then manipulated to flip upward, causing the filter cartridge 2 to flip upward.
[0037] When the positioning pin 17 on the right and the positioning pin 17 on the left are at the same level, the adjusting pin 19 on the right is inserted into the positioning frame 16 on the right. Then, the adjusting pin 19 on the right is rotated clockwise to press against the second positioning frame 11. The moving pin 10 is moved to the left along the adjusting frame 9. The moving pin 10 moves to the left along the buffer rod 21 to compress the buffer spring 22. The moving pin 10 moves to the left, which drives the second positioning frame 11 to move to the left. The second positioning frame 11 moves to the left, which drives the filter cylinder 2 to move to the left, so that the right end of the positioning tube 3 is inserted into the hole on the flange of the filter cylinder 2. The magnets 18 on the left and right sides attract each other. Then, the external bolt passes through the positioning tube 3 and cooperates with the nut to fix the pipe body 1 and the filter cylinder 2.
[0038] Loosen the two sets of adjusting pins 19 counterclockwise, manipulate the two sets of positioning frames 16 to move outward, and drive the two sets of positioning columns 17 to move outward, so that the two sets of positioning columns 17 move outward and are pulled out from the positioning tube 3 located on the front side. The operator takes out the assembled pipe body 1 and filter cylinder 2 from the first positioning frame 7 and the second positioning frame 11.
[0039] Repeat the above connection steps to connect the pipe body 1 to the output end of the external water pump.
[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
