Description

Technical Field

[0001] The utility model relates to the field of pumped storage power stations, in particular to a vehicle for underground lifting construction in an inclined shaft of a pumped storage power station. Background Art

[0002] A water storage power station is a facility that uses electricity for regulation, storage and power generation. Its main principle is to use electricity to drive a water pump to pump water from a low-level reservoir to a high-level reservoir, and release water to generate electricity during peak electricity demand. The inclined shaft is an important channel connecting the high-level reservoir and the low-level reservoir. It is usually used for the transportation of water and the entry and exit of equipment. The quality of the inclined shaft construction directly affects the operating efficiency and safety of the power station. The underground lifting construction vehicle of the inclined shaft of the pumped storage power station is used to lift and lower materials perpendicular to the direction of the inclined shaft track.

[0003] In existing technology, construction vehicles are typically pulled along inclined shaft tracks using a winch and wire rope. Upon reaching the loading point, materials and equipment are directly raised and lowered. This results in poor overall positional stability for the construction vehicle. The height fluctuations of the materials and equipment often cause the vehicle's center of gravity to shift, making it prone to shaking and posing a safety hazard. Utility Model Content

[0005] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0006] A pumped storage power station inclined shaft underground lifting construction vehicle travels on an inclined shaft track, and a winch is provided at the top of the inclined shaft for pulling the underground lifting construction vehicle; the underground lifting construction vehicle comprises:

[0007] horizontal board;

[0008] The vertical plate is arranged on the upper surface of the middle part of the horizontal plate, is perpendicular to the horizontal plate, and has a T-shaped slide groove on the right side, the T-shaped slide groove is perpendicular to the horizontal plate, and a T-shaped slider is slidably arranged in the T-shaped slide groove; a rotating bracket is provided on the left side of the vertical plate, and the winding roller is rotatably arranged on the rotating bracket; and further includes a first sprocket provided at one end of the winding roller, the first sprocket being coaxial with the winding roller;

[0009] A driving motor has a second sprocket on its output shaft, and the second sprocket drives the first sprocket to rotate through a toothed chain;

[0010] The storage box is set on the right side of the vertical plate, and the left side is fixedly connected to the T-shaped slider. There is a connecting ring on the top. The wire rope wound on the winding roller passes through the guide wheel on the top surface of the vertical plate and is connected to the connecting ring.

[0011] Multiple hydraulic telescopic rods are connected to the lower surface of the horizontal plate at the top and the upper surface of the lifting plate at the bottom. The lower surface of the lifting plate is also provided with moving wheels that match the inclined shaft track; the lower surface of the horizontal plate is also provided with a baffle plate; the baffle plate is arranged around the lifting plate, and a limiting groove is provided at the bottom that matches the inclined shaft track.

[0012] In particular, it also includes a sliding rod vertically arranged on the right side of the storage box and in the same direction as the T-shaped sliding groove. A sliding plate slidably sleeved on the sliding rod is provided on the right side of the storage box.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0023] like Figure 1 、 Figure 2 and Figure 3 As shown, a pumped storage power station inclined shaft underground lifting construction vehicle travels on the inclined shaft track, and a winch is also provided at the top of the inclined shaft for pulling the underground lifting construction vehicle; the underground lifting construction vehicle includes:

[0024] horizontal board 1;

[0025] The vertical plate 2 is arranged on the upper surface of the middle part of the horizontal plate 1 and is perpendicular to the horizontal plate 1. A T-shaped slide groove 201 is opened on the right side. The T-shaped slide groove 201 is perpendicular to the horizontal plate 1. A T-shaped slider 202 is slidably arranged in the T-shaped slide groove 201; a rotating bracket 203 is provided on the left side of the vertical plate 2, and a winding roller 204 is rotatably arranged on the rotating bracket 203; and a first sprocket 205 is also provided at one end of the winding roller 204, and the first sprocket 205 is coaxial with the winding roller 204;

[0026] The drive motor 3 has a second sprocket 301 on its output shaft, and the second sprocket 301 drives the first sprocket 205 to rotate through a toothed chain 302;

[0027] The storage box 4 is arranged on the right side of the vertical plate 2, and is fixedly connected to the T-shaped slider 202 on the left side. A connecting ring 401 is provided on the top. The steel wire rope 403 wound on the winding roller 204 passes around the guide wheel 402 on the top surface of the vertical plate 2 and is connected to the connecting ring 401;

[0028] Multiple hydraulic telescopic rods 501 are connected to the lower surface of the horizontal plate 1 at the top and the upper surface of the lifting plate 502 at the bottom. The lower surface of the lifting plate 502 is also provided with a moving wheel 504 that matches the inclined shaft track; the lower surface of the horizontal plate 1 is also provided with a baffle plate 503; the baffle plate 503 is arranged around the lifting plate 502, and a limiting groove 507 that matches the inclined shaft track is provided at the bottom.

[0029] In the present invention, the storage box 4 is primarily used for storing materials and equipment. To prevent the materials and equipment from shaking during transportation, they need to be reinforced and tied using straps or ropes. Once the materials and equipment are loaded and tied, the hydraulic telescopic rod 501 is controlled to extend, causing the lifting plate 502 to move downward, driving the moving wheels 504 to extend out of the bottom of the enclosure plate 503 and into the inclined shaft track, thereby lifting the upper structure as a whole. A winch is provided at the top of the inclined shaft for pulling the device of the present invention, and the entire device is lowered by the winch and steel cables. After being lowered to the set point, the hydraulic telescopic rod 501 is controlled to retract, retracting the moving wheels 504 into the enclosure plate 503, so that the enclosure plate 503 fits against the inclined shaft track, and the inclined shaft track is embedded in the limiting groove 507, thereby limiting the horizontal displacement of the underground lifting construction vehicle and preventing shaking. Then, by starting the drive motor 3, the drive motor 3 drives the first sprocket 205 to rotate via the second sprocket 301 and the toothed chain 302, thereby rotating the winding roller 204 and winding the wire rope 403 of the winding roller 204. After the wire rope 403 passes around the guide wheel 402, it pulls the connecting ring 401 to move the storage box 4 upward, thereby achieving the upward movement of materials and equipment in a direction perpendicular to the inclined shaft track. During this process, because the left side of the storage box 4 is connected to the T-shaped slide 202 in the T-shaped chute 201 on the right side of the riser 2, the storage box 4 will not shake in the horizontal or vertical direction, effectively ensuring the stability of the storage box 4 during the lifting process. The lowering process of the storage box 4 is the opposite of the above process, so it will not be repeated here.

[0030] As a preferred embodiment, it further includes a sliding rod 601 vertically arranged on the right side of the storage box 4 and in the same direction as the T-shaped sliding groove 201 , and a sliding plate 602 slidably mounted on the sliding rod 601 is provided on the right side of the storage box 4 .

[0031] In this embodiment, by setting a sliding rod 601, and through the sliding plate 602 on the right side of the storage box 4 working together with the sliding rod 601, the stability of the storage box 4 during the lifting process is further ensured. At the same time, the sliding rod 601 can also assist in bearing part of the load during the entire lifting process, further enhancing the stability of the device of the utility model during use.

[0032] As a preferred embodiment, a plurality of guide holes 505 are further provided on the lifting plate 502 , and a plurality of guide rods 506 perpendicular to the horizontal plate 1 are provided on the lower surface of the horizontal plate 1 , and the guide rods 506 correspond to the guide holes 505 one by one.

[0033] In this embodiment, guide holes 505 are provided on the lifting plate 502, and guide rods 506 corresponding to the guide holes 505 are provided on the lower surface of the horizontal plate 1, thereby ensuring that the lifting plate 502 is always moving in a direction perpendicular to the horizontal plate 1 during the process of lifting and retracting the moving wheels 504, thereby ensuring that the overall position of the device does not change and ensuring the accuracy of the transportation points during the transportation of materials and equipment.

[0034] As a preferred embodiment, a side surface of the enclosure plate 503 is further provided with an inspection door.

[0035] In this embodiment, an inspection door is provided to facilitate the inspection and maintenance of the internal structure of the baffle plate 503 by the staff.

[0036] As a preferred embodiment, the upper surfaces of the left and right sides of the horizontal plate 1 are further provided with a plurality of electric telescopic rods 701 perpendicular to the horizontal plate 1. The piston rods of the electric telescopic rods 701 vertically penetrate the horizontal plate 1 and are connected to the positioning plate 702 below the horizontal plate 1. The lower surface of the positioning plate 702 is provided with a plurality of positioning cones 703.

[0037] Furthermore, a control box is located on the horizontal plate 1, which houses and protects the control components within. The control box houses a controller and a junction box. The left side of the controller is fixedly connected to the right side of the junction box, and the bottoms of the controller and junction box are both fixedly connected to the bottom of the control box's interior. The controller controls the circuitry, thereby controlling the operating status of the underground lifting and construction vehicles in the inclined shaft of the pumped-storage power station. The junction box allows for the connection and transmission of electrical energy.

[0038] There are three sets of sliding rods 601 , T-shaped sliding grooves 201 and T-shaped sliding blocks 202 , thereby further improving the stability of the storage box 4 when moving up and down.

[0039] In this embodiment, a reinforcement structure is provided for further reinforcing the device of the utility model. Specifically, by controlling the extension of the electric telescopic rod 701, its piston rod penetrates the horizontal plate 1 and drives the positioning plate 702 to move downward, forcing the positioning cone 703 on the lower surface of the positioning plate 702 to insert into the soil layer on both sides of the inclined shaft track, thereby playing an auxiliary reinforcement role and further enhancing the stability of the device of the utility model during use.
