Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mine drainage, in particular to a pipeline hanging water pump mine drainage structure. BACKGROUND

[0002] In mine exploitation operations, shaft drainage is a key link to ensure the safety of underground construction and the continuity of operations, mainly covering two application scenarios of shaft water chasing and shaft bottom drainage. However, the current drainage technical solution widely used in the industry has significant shortcomings in temporary facility construction, construction period, operation safety, and adaptability, etc., and is difficult to meet the efficient, flexible, and safe mine production requirements. The specific problems are as follows: The existing shaft water chasing operation needs to rely on a large number of temporary facilities to build, so as to realize the drainage function. Specifically, auxiliary structures such as a stable car, a head pulley platform, and a hanging platform need to be constructed in advance. The construction of these temporary facilities not only needs to invest a large amount of human and material resources, but also occupies a long construction preparation time. At the same time, the pipeline and cable used for drainage need to be hung by a steel wire rope, and the multi-stage centrifugal pump is installed on the hanging platform. The overall system has high installation complexity and large amount of measures engineering. In addition, the stability of the temporary facilities is greatly affected by the construction quality and the site environment, and is prone to risks such as shaking and displacement during the water chasing operation, further increasing the operation safety hazards.

[0003] For shaft bottom drainage, the existing solution usually requires excavating and constructing a fixed drainage pump house in the middle section of the shaft, and constructing a water sump. During operation, the accumulated water in the shaft bottom water pocket needs to be drained to the pump house water sump by a submersible pump, and then the multi-stage centrifugal pump fixedly installed in the pump house is used to drain the water along the pipeline to the ground. In this process, the pipeline and cable need to be hung by a steel wire rope and fixed to the shaft wall, which not only has a complicated installation procedure, but also has a difficult installation precision to guarantee due to the limitation of the underground space. At the same time, the construction period of the underground pump house and water sump is long, which will significantly prolong the overall construction progress of the mine and increase the project cost.

[0004] The pipeline hooks in the existing drainage structure are designed with fixed sizes, and the horizontal position thereof cannot be adjusted according to the actual diameter of the shaft. When facing shafts of different sizes (such as main shafts, auxiliary shafts, and air shafts with large diameter differences), hooks of different specifications need to be customized, which not only increases the cost of equipment procurement and replacement, but also reduces the universality of the drainage system, making it difficult to quickly adapt to diversified shaft drainage requirements.

[0005] In the existing technology, the cable is fixed separately from the pipeline or is associated with the pipeline only by a simple steel wire rope binding method, and lacks a special clamping structure. In shaft drainage operations, water flow impact and pipeline vibration can easily cause the cable to deviate and loosen, and even cause damage to the insulation layer due to friction with the pipeline, resulting in safety accidents such as electric leakage and short circuit, which seriously threatens the safety of underground operation personnel and equipment.

[0006] Based on this, the scheme proposes a pipeline hanging water pump mine drainage structure. SUMMARY

The mounting block 2 on each drainage pipe 4 fixes the power cable 3 through the cable clamping structure, so as to avoid disconnection or friction of the power cable 3 and ensure power supply safety. The principle of the cable clamping structure is as follows: when it is necessary to fix the power cable 3, the mounting block 2 is rotated inward to push the 11, 11 on both sides of the mounting block 2, so as to drive the corresponding sliding sleeve 10 to move along the slide rod 12. Then, the cable clamping block 13 is driven to move towards the power cable 3, until the two cable clamping blocks 13 completely adhere to the outer wall of the power cable 3, so as to stably clamp the power cable 3 through the cable clamping block 13. The fixed plate 6 is assembled on the topmost drainage pipe 4 through the locking clamp 9, and the fixed block 16 of the connecting part of the steel wire hoisting rope 7 is fixed with the well mouth, so as to complete the hanging installation of the entire drainage structure.

A pipeline-suspended water pump mine drainage structure according to claim 4, characterized in that: The pushing assembly includes a connecting rod (20), a sliding block (19), a square block (23), a crossbar (24), and a connecting block (14). The lead screw guide sleeve (22) is hinged to the two connecting rods (20). The end of the connecting rod (20) away from the lead screw guide sleeve (22) is hinged to the sliding block (19). The sliding block (19) is slidably assembled in the square block (23). Two sets of crossbars (24) are slidably installed on both sides of the fixed plate (6). One end of the two crossbars (24) on the same side is fixedly installed with the same connecting block (14). The other ends of the two crossbars (24) on the same side are respectively fixedly connected to the corresponding square blocks (23). When the lead screw guide sleeve (22) moves, it drives the sliding block (19) to slide in the square block (23) through the connecting rod (20), thereby pushing the crossbar (24) to slide along the fixed plate (6) and driving the connecting block (14) to move synchronously.

7. A pipeline-suspended water pump mine drainage structure according to claim 1, characterized in that: The connecting part of the wire rope (7) is a fixing block (16). The fixing block (16) has an installation hole for assembling a fixing component. The fixing component passes through the installation hole to fix the fixing block (16) at the wellhead. Through the cooperation of the fixing block (16) and the fixing component, the wire rope (7) is stably fixed at the wellhead.

8. A pipeline-suspended water pump mine drainage structure according to claim 1, characterized in that, A slide rail is fixedly installed inside the fixed plate (6), and a slider is slidably installed on the slide rail. The slide rail is arranged along the axial direction of the lead screw (21), and the slider is fixedly connected to the lead screw guide sleeve (22).
