Description

Technical Field

[0001] The utility model relates to a water pump lifting and moving device for a fixed pump station in a long tunnel, belonging to the technical field of tunnel construction. Background Art

[0002] During tunnel construction, wastewater, rock seepage, and water gushing from surrounding rocks all impact the surrounding environment and ecological protection, particularly in ecologically fragile areas like plateaus. Therefore, the treatment of tunnel sewage is a crucial issue in green construction. To this end, plateau tunnel construction employs a clean and dirty water diversion system. This system requires the installation of fixed pumping stations within the tunnel to initially precipitate impurities such as sand, gravel, and sludge, and then pump the water out to sedimentation tanks and treatment stations outside the tunnel.

[0003] As the length of tunnel excavation continues to increase, the number of fixed pumping stations is also increasing, and the installation and maintenance of pumping station equipment are also increasing. The lifting workload of pumping station equipment is also increasing. The high-power water pumps equipped in fixed pumping stations can weigh up to 1.2 tons. Due to the small internal space of the pumping station, large lifting equipment is difficult to operate. During the lifting construction of the pumping station equipment, it will occupy the tunnel driving lane for a long time, affecting the passage of other construction machinery and equipment, and indirectly affecting the progress of tunnel construction. At present, there is also a method of setting up a support frame in the tunnel and setting up a longitudinal and transverse movement mechanism on the support frame to solve the problem of lifting fixed pumping station equipment in the tunnel. However, setting up a support frame in the tunnel will occupy the internal space of the tunnel, and the arrangement of the support frame is inconvenient. The workload of setting up the support frame is large, which affects construction efficiency. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, the utility model provides a water pump lifting and moving device for a fixed pump station in a long tunnel, which is convenient for lifting pump station equipment and can save space inside the tunnel.

[0005] The utility model is realized by the following technical scheme: a water pump lifting and moving device for a fixed pump station in a long tunnel, characterized in that it comprises two longitudinal rails, a transverse rail, a mobile hoist, and a longitudinal rail fixing device. The two longitudinal rails are respectively arranged on both sides above the fixed pump station along the longitudinal direction of the tunnel. The longitudinal rails are fixedly connected to the arch above the fixed pump station through a plurality of longitudinal rail fixing devices arranged at intervals. The longitudinal rail fixing device comprises an embedded steel plate embedded in the secondary lining concrete of the arch and a triangular fixed device fixedly connected to the outside of the embedded steel plate. The triangular body connector is provided with a plurality of anchor holes on the embedded steel plate, and the embedded steel plate is anchored in the second lining concrete of the arch through the anchor bars. The longitudinal beam track is an I-beam, and the upper end of the longitudinal beam track is fixedly connected to the triangular body connector through bolts. The crossbeam track is an I-beam, and the two ends of the crossbeam track are movably matched with the lower flange of the I-beam of the longitudinal beam track through a traveling pulley mechanism. The mobile hoist is movably set on the crossbeam track, and both ends of the longitudinal beam track and the two ends of the crossbeam track are provided with limited buffer devices.

[0006] In this utility model, the crossbeam track can move longitudinally along the longitudinal track via the running pulley mechanisms at both ends, and the mobile hoist can move laterally along the crossbeam track, thereby enabling rapid movement of various equipment within the fixed pump station area. The crossbeam track and mobile hoist can be limited and buffered by the limiter and buffer device, ensuring the safety of their movement. The longitudinal track is fixed to the tunnel vault position by the longitudinal track fixing device, which saves space within the tunnel and does not affect the passage of other construction machinery and equipment within the tunnel. Furthermore, it is easy to arrange and is not easily affected by other factors within the tunnel.

[0007] Furthermore, to ensure the safety and reliability of the device, each longitudinal beam track is also provided with at least two anti-slip steel wire ropes, one end of the anti-slip steel wire rope is connected to the longitudinal beam track, and the other end of the anti-slip steel wire rope is fixedly connected to the anti-slip steel plate embedded in the second lining concrete of the arch.

[0008] Furthermore, the position limiting buffer device is a rubber buffer.

[0009] Furthermore, in order to improve the anchoring force of the embedded parts, two rows of full-length steel bars are embedded in the second lining concrete inside the embedded steel plate, and the anchor bars of the embedded steel plate are welded to the full-length steel bars.

[0010] Furthermore, the full-length steel bar is threaded steel bar with a length of 1m.

[0011] The beneficial effects of the present invention are as follows: the present invention has a simple structure, and the longitudinal and transverse movements of the mobile hoist can be conveniently realized through the longitudinal beam rail and the transverse beam rail, and the rapid movement of various equipment within the fixed pump station area can be realized. When the water pump inside the fixed pump station needs to be moved or the number of water pumps needs to be increased and the water pump position needs to be rearranged, the water pump or other equipment can be quickly moved by the lifting and moving device, thereby improving the flexibility and convenience of the internal movement of the fixed pump station; the present invention saves space inside the tunnel by fixing the longitudinal beam rail at the tunnel arch position using the longitudinal beam rail fixing device, does not affect the passage of other construction machinery and equipment in the tunnel, and is easy to arrange and is not easily affected by other factors in the tunnel, and the construction of the present invention is simple during setting, and the implementation cost is low.

[0026] As shown in the accompanying drawings, a device for hoisting and moving water pumps at a fixed pump station in a long tunnel comprises a mobile hoist 1, a horizontal rail 2, two longitudinal rails 3, and longitudinal rail fixtures. The longitudinal rails 3 are 22a I-beams and are positioned longitudinally along the tunnel, one above the fixed pump station. The longitudinal rails 3 are fixedly connected to the dome above the fixed pump station via multiple, spaced-apart longitudinal rail fixtures. The longitudinal rail fixing device includes an embedded steel plate 8 embedded in the secondary concrete lining of the vault and a triangular connector 6 fixedly connected to the outside of the embedded steel plate 8. The embedded steel plate 8 is embedded in the secondary concrete lining of the vault before the fixed pump station vault formwork is installed. The embedded steel plate 8 is a 16mm thick steel plate processed into a 20cm*30cm size. The embedded steel plate 8 is provided with multiple anchor holes 13 with a diameter of 25mm. The embedded steel plate 8 is anchored in the secondary concrete lining of the vault via anchor bars 9. The outer surface of the embedded steel plate 8 is in close contact with the formwork. The anchor bars 9 are threaded steel bars with a diameter of 18mm and are anchored into the concrete for a length of not less than 50cm. To enhance the anchoring force of the embedded parts, in this embodiment, two rows of continuous steel bars 15 are embedded in the secondary concrete lining inside the embedded steel plate 8. The anchor bars 9 of the embedded steel plate are welded to the continuous steel bars 15. The through-length steel bar 15 is preferably a threaded steel bar with a diameter of not less than 16 mm, and the length of a single through-length steel bar 15 is 1 m. The triangular connector 6 is welded by three steel plates, and four bolt holes 12 are provided on the horizontal steel plate of the triangular connector 6. The inclined surface of the triangular connector 6 is welded to the embedded steel plate 8, and the horizontal steel plate of the triangular connector 6 is fixedly connected to the upper end of the longitudinal beam track 3 by bolts. The crossbeam track 2 is a 22a type I-beam, and the two ends of the crossbeam track 2 are movably matched with the lower flange of the I-beam of the longitudinal beam track 3 through a running pulley mechanism 5. The running pulley mechanism 5 is a prior art. The frame of the running pulley mechanism 5 is fixedly connected to the crossbeam track 2 by bolts, and it is matched with the lower flange of the I-beam through the running pulleys located on both sides of the I-beam web. Under the action of external force, its running pulley can move along the lower flange of the I-beam of the longitudinal beam track 3. The mobile hoist 1 is movably mounted on the crossbeam track 2. The mobile hoist 1 is also conventional technology and primarily comprises a running pulley 1.1, a running motor 1.2, and a lifting motor 1.3. Driven by the running motor 1.2, the mobile hoist 1 can move along the crossbeam track 2 via the running pulley 1.1, and can lift heavy objects such as water pumps via the lifting motor 1.3. To ensure safe operation of the equipment, a limiting buffer device is provided at both ends of the longitudinal beam track 3 and at both ends of the crossbeam track 2. The limiting buffer device comprises a limiting steel plate 7 and a rubber buffer 4. The rubber buffer 4 is bolted to the limiting steel plate 7, and the limiting steel plate 7 is welded and fixed to the longitudinal beam track 3 / crossbeam track 2. The limiting buffer device can limit and buffer the movement of the crossbeam track 2 and the mobile hoist 1.

[0027] To ensure the safety and reliability of the device, in this embodiment, each longitudinal track is also provided with at least two anti-slip steel wire ropes 11. One end of the anti-slip steel wire rope 11 is connected to the longitudinal track 3, and the other end of the anti-slip steel wire rope 11 is fixedly connected to the anti-slip steel plate 10 embedded in the secondary concrete lining of the vault. The anti-slip steel plate 10 is a 15cm*15cm steel plate with multiple anchor rod holes 14. The anti-slip steel plate 10 is anchored in the secondary concrete lining of the vault via anchor rods. The anchor rods are threaded steel bars with a diameter of 18mm and are anchored into the concrete for a length of not less than 45cm. The number of anti-slip steel wire ropes 11 can be set according to the load-bearing capacity. In this embodiment, one anti-slip steel wire rope 11 is provided at each end of the longitudinal track.

[0028] When the utility model is used, the water pump and other equipment that needs to be lifted can be lifted by the mobile hoist 1. The mobile hoist 1 can be moved horizontally by running along the crossbeam track 2. Under the action of external force, the crossbeam track 2 can be moved longitudinally along the longitudinal beam track 3 via the running pulley mechanism 5, thereby lifting the water pump and other equipment to the designated location, realizing the mobile lifting of equipment in the fixed pump station. Within the fixed pump station area, the water pump position can be adjusted or a temporary water pump can be added according to the specific conditions of on-site sewage diversion, thereby improving the water storage and drainage capacity of the pump station.
