Description

Technical Field

[0001] This application relates to the technical field of mine backfilling, and in particular to a multi-directional switching device for a mine backfilling slurry conveying pipeline. Background Technology

[0002] With the continuous improvement of safety and environmental protection standards in mining, backfilling mining has achieved tremendous development and widespread application in recent years. After the backfill slurry is prepared on the surface, it is transported to the underground stope through backfilling pipelines; when the main pipeline extends from the surface preparation station to the vicinity of the stope, generally one main pipeline corresponds to multiple branch pipelines leading to different stopes.

[0003] During use, each discharge pipe is typically connected to the feed pipe via flanges according to the specific needs of the mining area. For example, when a mining area needs filling, the discharge pipe and feed pipe of that area are manually connected to ensure that the filling slurry can smoothly reach the target filling area. After filling is completed, the flange between the discharge pipe and the feed pipe is manually disconnected. This technique requires a lot of manpower, and the work of disassembling and assembling the flanges is complicated, resulting in low work efficiency and hindering large-scale application in mining production. Summary of the Invention

[0004] To facilitate operators in quickly adjusting the connection and closure between pipelines, this application provides a multi-directional switching device for mine filling slurry conveying pipelines.

[0010] Optionally, the end of the pre-positioning tube is provided with an insertion tube that is inserted into the switching tube, and the inner wall of the switching tube is provided with a bushing that mates with the insertion tube.

[0011] By adopting the above technical solution, the insertion tube is inserted into the switch tube, which improves the stability of the connection between the pre-connector tube and the switch tube. The bushing protects the inner wall of the switch tube and the outer wall of the insertion tube.

[0012] Optionally, a protective pad is provided between the first connecting plate and the second connecting plate.

[0013] By adopting the above technical solution and setting the protective pad, it is convenient to protect the pipe openings where the first connecting plate and the second connecting plate are connected, reduce wear between the pipe openings, and extend the service life.

The first support plate is located below the pre-connector pipe, the second support plate is located below the on / off pipe, and the third support plate is located below the discharge pipe.

[0017] By adopting the above technical solution, the first support plate, the second support plate and the third support plate support the pre-pipe, the on / off pipe and the discharge pipe.

[0025] The present application will be further described in detail below with reference to all the accompanying drawings.

[0026] This application discloses a multi-directional switching device for a mine filling slurry conveying pipeline.

[0027] Reference Figure 1 A multi-directional switching device for a mine filling slurry conveying pipeline includes a feed pipe 1, which is connected to an intermediate pipe 2. Several pre-pipes 3 are connected to the side of the intermediate pipe 2 away from the feed pipe 1. Each pre-pipe 3 is connected to a switch pipe 4 at its end away from the intermediate pipe 2. A discharge pipe 5 is connected to the side of the switch pipe 4 away from the pre-pipes 3. A switch valve 7 is installed on the switch pipe 4, which is connected to the pre-pipes 3 via a connecting assembly 6. The switch valve 7 controls the opening and closing of the switch pipe 4, thereby saving time and improving operational efficiency. The connecting assembly 6 facilitates quick connection between the pre-pipes 3 and the switch pipe 4.

[0028] Reference Figure 1 and Figure 2 The connecting assembly 6 includes a first connecting plate 61 and a second connecting plate 62. The first connecting plate 61 is mounted on the switching pipe 4, and the second connecting plate 62 is mounted on the pre-connecting pipe 3. Fixing plates 63 are hinged to both the upper and lower sides of the first connecting plate 61. A connecting screw 64 passes through the side of the fixing plate 63 furthest from the second connecting plate 62 and is inserted into the second connecting plate 62. Opening the fixing plate 63 causes the first connecting plate 61 and the second connecting plate 62 to fit together. Retracting the fixing plate 63 and tightening the connecting screw 64 fixes the connecting screw 64 to the second connecting plate 62, connecting the first connecting plate 61 and the second connecting plate 62, thereby connecting the pre-connecting pipe 3 to the switching pipe 4.

[0029] Reference Figure 2 The pre-insertion tube 3 has an insertion tube 31 at its end that is inserted into the switch tube 4. The inner wall of the switch tube 4 is provided with a bushing 41 that mates with the insertion tube 31. Inserting the insertion tube 31 into the switch tube 4 improves the stability of the connection between the pre-insertion tube 3 and the switch tube 4. The bushing 41 protects the inner wall of the switch tube 4 and the outer wall of the insertion tube 31.

[0030] Reference Figure 2 A protective pad 65 is provided between the first connecting plate 61 and the second connecting plate 62. The protective pad 65 facilitates the protection of the pipe openings where the first connecting plate 61 and the second connecting plate 62 are connected, reducing wear between the pipe openings and extending service life.

[0031] Reference Figure 1 The on / off valve 7 includes a valve body and a handle 71, with a sponge sleeve fitted onto the handle 71. The sponge sleeve protects the operator, while the handle 71 facilitates the control of the on / off valve 7.

[0032] Reference Figure 1 A base plate 8 is installed below the pre-feed pipe 3, the on / off pipe 4, and the discharge pipe 5. A first support plate 81, a second support plate 82, and a third support plate 83 are installed above the base plate 8. The first support plate 81 is located below the pre-feed pipe 3, the second support plate 82 is located below the on / off pipe 4, and the third support plate 83 is located below the discharge pipe 5. The first support plate 81, the second support plate 82, and the third support plate 83 support the pre-feed pipe 3, the on / off pipe 4, and the discharge pipe 5.

[0033] The implementation principle of the multi-directional switching device for a mine filling slurry conveying pipeline in this application embodiment is as follows: the pre-connecting pipe 3 and the on / off pipe 4 can be conveniently and quickly connected through the connecting component 6. When a certain stope needs to be filled, the handle 71 is turned to switch the on / off valve 7 to the connected state to fill the stope position. When a certain stope does not need to be filled, the handle 71 is turned to switch the on / off valve 7 to the closed state to connect / off the pipe wall of the pipe 4 and stop the filling work in that stope.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
