Description

Technical Field

[0001] The utility model belongs to the technical field of the installation of centrifugal pumps in underground mines, and particularly relates to an installation device for a centrifugal pump for draining water in an underground mine. Background Art

[0002] During the underground mining process, in order to maintain the safety of underground operations, it is necessary to drain the accumulated water in the mine. By draining the accumulated water in the mine, a safe working environment can be provided during the coal mining process, including the protection of equipment, manpower, etc.

[0003] In order to meet the drainage requirements, the current drainage method is to drain water through a large centrifugal pump. Specifically, a large centrifugal pump can meet the drainage operation requirements in the mine because of its high discharge capacity and large head.

[0004] Specifically, during the actual operation process, in order to keep the large centrifugal pump operating smoothly, the pump is often installed on a workbench. However, due to the relatively harsh working environment in the mine, during the working process, spalling and falling gangue often occur from the roof and sidewalls of the roadway. And the falling of gangue is extremely likely to cause damage to the equipment. Especially the centrifugal pump that is operating. At present, the workbench for installing the pump body does not have a protective structure for protecting the pump body, resulting in the pump body being impacted by the falling gangue during the actual working process, causing damage to the pump body.

[0005] At the same time, since the pump body is installed on the bearing platform, and the bearing platform is often a concrete structure laid in the roadway, during the operation of the centrifugal pump in the roadway, a large amplitude of vibration is generated, resulting in a significant reduction in the stability of the laid platform. Specifically, because the bearing platform in the mine is often directly poured in the roadway, due to reasons such as the lower layer of the foundation in the roadway, the bearing platform is more likely to be tilted as a whole, and the high-intensity vibration of the centrifugal pump further reduces the stability of the bearing platform. And the reduction in the stability of the bearing platform seriously affects the working safety and stability of the centrifugal pump. Summary of the Utility Model

[0006] Based on the above background, the purpose of the utility model is to provide an installation device for a centrifugal pump for draining water in an underground mine.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An installation device for a centrifugal pump for draining water in an underground mine, comprising a bearing platform for installing the centrifugal pump, and a gangue blocking mechanism is hinged at the top of the bearing platform;

[0009] The gangue blocking mechanism includes a plurality of arc-shaped frames hinged on the bearing platform, and a plurality of rib beam rods are fixedly connected between the arc-shaped frames;

[0010] The baffle mechanism further includes an arc-shaped baffle net fixedly connected to the arc-shaped frame, and the rib beam is supported inside the arc-shaped baffle net;

[0011] The arc-shaped frames are all locked to the top of the bearing platform through a locking structure;

[0012] The bottom of the bearing platform is fixedly connected with a bottom anchor mechanism, the bottom anchor mechanism includes a plurality of support beams, the bottom of the support beams is fixedly connected with a plurality of anchor plate structures, the anchor plate structure includes an anchor plate body, and both ends of the anchor plate body are integrally formed with anchor bends arranged in a bent manner.

[0013] Preferably, a pair of spaced ear seats are fixedly connected to one side of the top edge of the bearing platform, a long hinge rod is hinged between the ear seats, and the inner end of the arc-shaped frame is fixedly connected to the long hinge rod.

[0014] Preferably, the rib beams are arc-shaped and distributed between the arc-shaped frames.

[0015] Preferably, the locking structure includes a locking seat fixedly connected to the other side position of the top edge of the bearing platform, and a locking screw is fixedly connected to the outer end of the arc-shaped frame;

[0016] A bayonet adapted to the locking screw is provided on the locking seat, and a nut positioned outside the locking seat is threadedly connected to the locking screw.

[0017] Preferably, a pair of mounting seats are respectively fixedly connected to the front and rear sides of the top of the bearing platform, and assembly holes are provided on the mounting seats.

[0018] Preferably, the longitudinal cross-sectional shape of the support beam is T-shaped.

[0019] Preferably, a plurality of welding columns are respectively welded to the bottom of the support beam, and the welding columns are welded and fixed to the top of the anchor plate body.

[0020] Preferably, the anchor bend includes an upper anchor bend and a lower anchor bend;

[0021] The upper anchor bend is bent upward, and the lower anchor bend is bent downward.

[0022] Preferably, the rib beam penetrates through the arc-shaped frame;

[0023] The front and rear ends of the rib beam are welded to the mutually facing side walls of the arc-shaped frames at the front and rear ends.

[0024] The utility model has the following beneficial effects:

[0025] 1. During the implementation process, the flipping arc-shaped frame - arc-shaped retaining net structure is flipped to cover the centrifugal water pump. During the operation, when the gangue from the falling or peeling roadway drops, at this time, the gangue hits the arc-shaped frame - rib beam rod - arc-shaped retaining net. Protected by the arc-shaped skeleton formed by the arc-shaped frame - rib beam rod, even if the gangue hits the arc-shaped frame - rib beam rod structure, the centrifugal pump is protected under the protection of the arc-shaped frame - rib beam rod structure. For small pieces of gangue, they are protected by the arc-shaped retaining net structure.

[0026] 2. During the construction of the bearing platform, concrete is pre-poured at the construction location, and the support beam and anchor plate structure are poured into the concrete base layer. After pouring, due to the strengthening support of the support beam and the anchoring of the anchor bending part in the concrete structure layer, under the support and anchoring effects, the bearing platform can still maintain its stability after resisting the vibration of the long-term operation of the centrifugal pump, and the role of the anchor bending part is to increase the grip force with the poured concrete structure. Therefore, the ability of the bearing platform to resist offset and tilt is greatly improved. Even if the base layer sinks slightly, the platform can still maintain high stability such as horizontality. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Embodiment 1

[0038] As Figures 1 - 5 shown, a centrifugal water pump installation device for underground drainage in mines includes a bearing platform 1 for installing a centrifugal water pump (specifically, in accordance with the existing method, a pair of mounting seats 11 for installing a centrifugal pump are respectively fixed on the front and rear sides of the top of the bearing platform 1 at intervals left and right, and the centrifugal pump is placed and installed. In accordance with the existing method, the base at the bottom of the centrifugal pump is fixed to the assembly holes on the mounting seats 11 through screws and nuts).

[0039] A gangue blocking mechanism is hinged to the top of the bearing platform 1. By means of the gangue blocking mechanism, the gangue blocking mechanism is flipped to cover and protect the large centrifugal pump installed on the bearing platform 1, and the pump body is protected in this way.

[0040] Specifically, the gangue blocking mechanism includes a plurality of arc-shaped frames 21 hinged to the bearing platform 1, and a plurality of rib beam rods 22 are fixedly connected between the arc-shaped frames 21; the rib beam rods 22 are distributed in an arc shape (that is, the rib beam rods 22 are distributed in an arc along the radian of the arc-shaped frames 21). The rib beam rods 22 penetrate between the arc-shaped frames 21, and their front and rear ends are fixed on the side walls of the arc-shaped frames 21 facing each other.

[0041] The hinged manner of the arc-shaped frame 21 is as follows: on the right side of the top edge of the bearing platform 1, a pair of ear seats 241 arranged at intervals front and back are fixedly connected. A long hinge rod 24 is hinged between the ear seats 241, and the inner end of the arc-shaped frame 21 is fixedly connected to the long hinge rod 24. At the same time, the above-mentioned gangue blocking mechanism further includes an arc-shaped retaining net 23 fixedly connected to the arc-shaped frame 21, and the rib beam rod 22 is supported on the inner side of the arc-shaped retaining net 23.

[0042] The bottom and the front and rear ends of the arc-shaped retaining net 23 are fixedly connected to the arc-shaped frame 21. And it is supported by the rib beam rod 22 at the bottom of the arc-shaped retaining net 23.

[0043] During the working process, the arc-shaped frame 21 - arc-shaped retaining net 23 structure is flipped until the arc-shaped frame 21 - arc-shaped retaining net 23 is flipped and covers the centrifugal pump. During the working process, when the gangue falling or spalling from the roadway drops, at this time, the gangue impacts on the arc-shaped frame 21 - rib beam rod 22 - arc-shaped retaining net 23. Under the protection of the arc-shaped framework formed by the arc-shaped frame 21 - rib beam rod 22, even if the gangue impacts on the arc-shaped frame 21 - rib beam rod 22 structure, the centrifugal pump is protected under the protection of the arc-shaped frame 21 - rib beam rod 22 structure. For small pieces of gangue, they are protected by the arc-shaped retaining net 23 structure.

[0044] Embodiment 2

[0045] As Figures 1 - 5 shown, on the basis of the structure of Embodiment 1 in this embodiment, the above-mentioned arc-shaped frames 21 are all locked to the top of the bearing platform 1 through a locking structure. After the arc-shaped frame 21 - rib beam rod 22 structure is flipped and covered, it is locked through the locking structure.

[0046] Specifically, the locking structure includes a locking seat 31 fixedly connected to the other side position of the top edge of the bearing platform 1, and a locking screw 32 is fixedly connected to the outer end of the arc-shaped frame 21; a bayonet matching the locking screw 32 is opened on the locking seat 31, and a nut positioned outside the locking seat 31 is threadedly connected to the locking screw 32.

[0047] During the flipping process, the locking screw 32 fixed to the outer end of the arc-shaped frame 21 is inserted into the bayonet and locked by the nut.

[0048] Embodiment 3

[0049] As Figures 1 - 5 shown, on the basis of the structure of Embodiment 2 in this embodiment, a bottom anchor mechanism is fixedly connected to the bottom of the above-mentioned bearing platform 1, and the stability of the bearing platform 1 is increased through the bottom anchor mechanism, which is used to solve the defects that the stability of the bearing platform 1 is poor due to the vibration during the working process of the large centrifugal pump and the stability of the bearing platform 1 is reduced due to the foundation settlement of the bearing platform 1 poured in the roadway.

[0050] Specifically, the bottom anchor mechanism includes a plurality of support beams 4 with a T-shaped structure arranged at intervals left and right. A plurality of anchor plate structures are fixedly connected to the bottom of the support beam 4. The anchor plate structure includes an anchor plate body 5, and both ends of the anchor plate body 5 are integrally formed with anchor bending parts 51 arranged in a bent manner.

[0051] Meanwhile, a plurality of welding columns 41 are respectively welded to the bottom of the support beam 4, and the welding columns 41 are welded and fixed to the top of the anchor plate body 5. The anchor bending part 51 includes an upper anchor bending part and a lower anchor bending part; the upper anchor bending part is bent upward, and the lower anchor bending part is bent downward.

[0052] During the construction process of the bearing platform 1, concrete is pre-poured at the construction position, and the support beam 4 and the anchor plate structure are poured into the concrete ground base. After the pouring is completed, due to the support beam 4 playing a role in strengthening the support and the anchor bending part 51 being anchored in the concrete structure layer, under the support and anchoring effects, the bearing platform 1 can still maintain its stability after resisting the vibration of the centrifugal pump during long-term operation. Moreover, the role of the anchor bending part 51 is to increase the grip force with the poured concrete structure. Therefore, the ability of the bearing platform 1 to resist offset and tilt is greatly improved. Even if the bottom base sinks slightly, the platform can still maintain a high stability such as horizontality.

[0053] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
