Description

Technical Field

[0001] This utility model relates to the field of shaft crane technology, specifically to a shaft crane for pumped storage hydropower stations. Background Technology

[0002] Pumped storage hydropower stations generally refer to pumped storage power stations, which use electricity generated during periods of low electricity load to pump water to an upper reservoir and release it to a lower reservoir to generate electricity during periods of high electricity load.

[0003] Among them, a special vertical shaft crane for pumped storage hydropower stations, with announcement number CN219408998U, includes a gantry, a trolley traveling mechanism, a lifting trolley, and an electrical system. The drum is equipped with a hook via a wire rope. The hook includes a frame and a hook body. The hook body is installed at the lower part of the frame. A pulley block is installed inside the frame. The pulley block includes at least two symmetrically arranged pulleys. There is a gap between the two pulleys to reduce the angle of the wire rope entry. The fixed end of the wire rope is connected to a rotating device for stress relief. The rotating device is installed on the trolley frame of the lifting trolley.

[0004] However, the length of the shafts used in existing pumped storage hydropower stations is usually fixed. Therefore, different diameter shafts are used depending on the actual usage environment, which affects the normal use of cranes. Utility Model Content

[0005] In view of the problems existing in the current pumped storage hydropower station shaft cranes, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a vertical shaft crane for pumped storage hydropower stations, which solves the problem that the length of the existing vertical shafts in pumped storage hydropower stations is usually fixed, so the crane is not suitable for different diameter shafts according to the actual use environment, thus affecting the normal use of the crane.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A vertical shaft crane for a pumped storage hydropower station includes a crossbeam and a fixed frame. Both ends of the crossbeam have grooves, and extension beams are slidably mounted inside each groove. A cavity is formed between the two grooves, and an adjustment mechanism is installed inside the cavity. Both extension beams move via the adjustment mechanism. Two mounting plates are fixedly connected to the upper surface of the fixed frame, and the crane body is fixedly connected to the lower surface of the fixed frame. One side of each mounting plate has a through hole, and a rotating rod is rotatably connected inside each through hole. One end of each rotating rod is fixedly fitted with a movable wheel. Movable grooves are formed on both sides of the crossbeam, and the two movable wheels are located inside the movable grooves. A drive mechanism is installed inside the fixed frame, and both rotating rods rotate via the drive mechanism.

[0009] Preferably, the adjusting mechanism includes a first motor, a first bevel gear, two second bevel gears, and two lead screws. The first motor is fixedly connected to the upper surface of the crossbeam. The output end of the first motor passes through the upper surface of the crossbeam and extends into the cavity. The first bevel gear is fixedly sleeved on the output end of the first motor. The two lead screws rotate in the interior of corresponding slide grooves. The two extension beams are threaded onto the rod walls of the lead screws. One end of each of the two lead screws passes through one side of the corresponding slide groove and extends into the cavity. The two second bevel gears are fixedly sleeved on the rod walls of one end of the corresponding lead screws and mesh with the first bevel gears.

[0010] Preferably, the drive mechanism includes a second motor, multiple transmission wheels, and two transmission belts. The second motor is fixedly connected inside the fixed frame. Each transmission wheel is fixedly sleeved on the output end of the second motor and the rod wall at one end of the rotating rod. The transmission belts are respectively sleeved on the outer surfaces of the corresponding two transmission wheels.

[0011] Preferably, protrusions are provided on both sides of the extension beam.

[0012] Preferably, the upper surface of the fixing frame has two strip holes, and the two strip holes are respectively matched with the corresponding transmission belts.

[0013] Preferably, a vertical beam is fixedly connected to the lower surface of one end of each of the two extension beams, and a caster wheel is fixedly connected to the lower end of each of the two vertical beams.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model, by starting the first motor, causes the first bevel gear to rotate, which in turn causes the two second bevel gears to rotate, thereby causing the two lead screws to rotate. Subsequently, the two extension beams can move left and right, thereby extending the overall length of the device, making it applicable to vertical shafts of different diameters, so that the crane body can be used normally.

[0016] 2. In this utility model, by starting the second motor, the two transmission wheels connected to it are rotated. Then, two transmission belts are used to rotate the other two transmission wheels, which in turn rotate the two rotating rods, that is, the two moving wheels, thereby allowing the crane body to move.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a vertical shaft crane for a pumped storage hydropower station.

[0025] This utility model provides, for example Figure 1-3The vertical shaft crane for a pumped storage hydropower station shown includes a crossbeam 1 and a fixed frame 2. Both ends of the crossbeam 1 have grooves, and extension beams 3 are slidably mounted inside each groove. A cavity is formed between the two grooves, and an adjustment mechanism is installed inside the cavity. Both extension beams 3 move through the adjustment mechanism. Two mounting plates 4 are fixedly connected to the upper surface of the fixed frame 2, and the crane body 16 is fixedly connected to the lower surface of the fixed frame 2. One side of each mounting plate 4 has a through hole, and a rotating rod 5 is rotatably connected inside each through hole. One end of each rotating rod 5 is fixedly fitted with a movable wheel 6. Movable grooves are formed on both sides of the crossbeam 1, and the two movable wheels 6 are located inside the movable grooves. A drive mechanism is installed inside the fixed frame 2, and both rotating rods 5 rotate through the drive mechanism.

[0026] The overall length of the device can be extended by sliding the two extension beams 3, thereby making the device applicable to shafts of different diameters so that the crane body 16 can be used normally.

[0027] In order for the two extension beams 3 to be movable, such as Figure 1-2 As shown, the adjustment mechanism includes a first motor 7, a first bevel gear 8, two second bevel gears 9, and two lead screws 10. The first motor 7 is fixedly connected to the upper surface of the crossbeam 1. The output end of the first motor 7 passes through the upper surface of the crossbeam 1 and extends into the cavity. The first bevel gear 8 is fixedly sleeved on the output end of the first motor 7. The two lead screws 10 rotate in the corresponding slide grooves. The two extension beams 3 are threaded onto the rod walls of the lead screws 10. One end of each lead screw 10 passes through one side of the corresponding slide groove and extends into the cavity. The two second bevel gears 9 are fixedly sleeved on the rod walls of one end of the corresponding lead screw 10 and mesh with the first bevel gear 8.

[0028] Start the first motor 7 to make the first bevel gear 8 rotate, which in turn makes the two second bevel gears 9 rotate, thereby making the two lead screws 10 rotate, and then the two extension beams 3 can move left and right.

[0029] In order to move the two crane bodies 16, as Figure 2 As shown, the drive mechanism includes a second motor 11, multiple transmission wheels 12, and two transmission belts 13. The second motor 11 is fixedly connected inside the fixed frame 2. Each transmission wheel 12 is fixedly sleeved on the output end of the second motor 11 and the rod wall at one end of the rotating rod 5. The transmission belts 13 are respectively sleeved on the outer surfaces of the corresponding two transmission wheels 12. Two strip holes are opened on the upper surface of the fixed frame 2, and the two strip holes are respectively matched with the corresponding transmission belts 13.

[0030] Start the second motor 11 to make the two drive wheels 12 connected to it rotate. Then, the two drive belts 13 can make the other two drive wheels 12 rotate, which in turn can make the two rotating rods 5 rotate, that is, the two moving wheels 6 rotate, so that the crane body 16 can move.

[0031] To facilitate the movement of the two movable wheels 6, such as Figure 2-3 As shown, protrusions are provided on both sides of the extension beam 3.

[0032] The two protruding blocks facilitate the movement of the two moving wheels 12.

[0033] To facilitate the movement of the two extended beams 3, such as Figure 1 As shown, vertical beams 14 are fixedly connected to the lower surfaces of one end of the two extension beams 3, and casters 15 are fixedly connected to the lower ends of the two vertical beams 14.

[0034] The two casters 15 facilitate the movement of the two vertical beams 14, which in turn facilitates the movement of the extension beam 3.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
