[0014] Preferably, the number of the clamping assemblies is two. The two clamping assemblies are connected by a telescopic sleeve.

[0015] Preferably, a method for using the equipment lifting device for a pumped-storage power station includes the following steps:

[0016] S1: The rotating platform drives the cantilever to move above the equipment through the truss. The suspension rope is moved above the equipment through the trolley and the bottom of the connection platform is abutted against the top of the equipment. The connection platform will give an upward pushing force to the extraction pipe. The extraction pipe drives the piston rod to move upward, so that the outer wall of the piston rod disengages and unlocks from the rotation guiding groove. The lengths of the fixed pipe and the telescopic rod are adjusted according to the length of the equipment, so that the grasping block is adapted to the length of the equipment. The grasping block also drives the telescopic sleeve to expand and contract. At the same time, the fixed block drives the telescopic block to expand and contract correspondingly through the connection platform.

[0017] S2: The coiling suspension rope gives an upward traction force to the hanging ring. The hanging ring acts on the connecting rod through the connecting block. The connecting rod drives the connecting pipe to move upward. The connecting pipe drives the clamping plate to move upward through the connecting block. Under the limiting action of the limiting fixed rod, the clamping plate deflects inward, so that the abutting block is inserted directly below the connecting platform. At the same time, the bottom of the limiting fixed rod abuts against the inner bottom wall of the connecting pipe, so that the connecting platform moves upward. The connecting platform deflects through the first deflecting plate. Under the limiting action of the second deflecting plate, the first deflecting plate drives the telescopic sleeve to axially slide relative to the fixed block. At the same time, the connecting platform drives the piston rod to move upward, so that the hydraulic oil in the oil storage pipe enters the extraction pipe. The piston block moves downward under the pressure and compresses the return spring.

[0018] S3: When the telescopic sleeve contracts along the fixed block, it will drive the grasping block to contract inward, so that the inner side wall of the grasping block abuts against the outer wall of the equipment. When the telescopic sleeve slides on the outer wall of the fixed block, the through rod will extend out through the through hole and abut against the outer wall of the rotating block. After receiving the driving force, the rotating block will deflect around the support block. The rotating block will push the grasping claw to extend out of the grasping block to the bottom of the equipment. When the rotating block deflects, it will push the jacking block to move inward. The jacking block will push the deflecting block to deflect out of the grasping block and abut against the outer wall of the equipment. When the connecting platform moves upward, it will pull the steel rope upward. The upward movement of the steel rope will cause the articulated blocks to deflect, so that the articulated blocks deflect inward and fit against the outer wall of the equipment in an arc shape. At this time, the telescopic sleeve stops sliding on the outer wall of the fixed block, and the first deflecting plate and the second deflecting plate stop moving, so that the fixed block follows the connecting platform to move upward, thus suspending the equipment.

[0019] The present invention provides an equipment lifting device for a pumped-storage power station and its use method. Compared with the prior art, it has the following beneficial effects:

[0020] (1) Through the mutual cooperation of the stretching component, the telescopic component and the grasping and clamping component, after the grasping claw abuts against the outer wall of the equipment, the equipment can be grasped and lifted, eliminating the need for manual bundling or assembly by workers, and reducing the pulling intensity of the workers.

[0021] (2) Through the mutual cooperation of the grasping and clamping component and the auxiliary component, the equipment is assisted to be clamped from the outside during the lifting process of the equipment, avoiding the equipment from slipping during the hoisting process and effectively guaranteeing the personal safety of the workers.

[0022] (3) The equipment lifting device for the pumped-storage power station and its usage method, through the coordinated use of the stretching component, telescopic component, and gripping component, the extraction pipe drives the piston rod to move, enabling the state of the piston rod in the connection platform to change from the locked state to the unlocked state, and enabling the device to be reset by the hydraulic oil, return spring, and piston block in the oil storage pipe after hoisting, without the need for manual adjustment.

[0045] A method for using an equipment hoisting device for a pumped - storage power station includes the following steps:

[0046] S1: The rotating table 1 drives the cantilever 3 to move above the equipment through the truss 2. The suspension rope 5 is moved above the equipment through the trolley 4 and the bottom of the connecting table 710 is made to abut against the top of the equipment. The connecting table 710 gives an upward pushing force to the extraction pipe 705. The extraction pipe 705 drives the piston rod 706 to move upward, causing the outer wall of the piston rod 706 to disengage and unlock from the rotation guiding groove. Adjust the lengths of the fixed pipe 602 and the telescopic rod 603 according to the length of the equipment, so that the grasping block 801 fits the length of the equipment. The grasping block 801 also drives the telescopic sleeve to expand and contract. At the same time, the fixed block 703 drives the telescopic block 709 to expand and contract correspondingly through the connecting table 710.

[0047] S2: Wind up the suspension rope 5. The suspension rope 5 gives an upward pulling force to the hanging ring 601. The hanging ring 601 acts on the connecting rod 605 through the connecting block 604. The connecting rod 605 drives the connecting pipe 606 to move upward. The connecting pipe 606 drives the clamping plate 608 to move upward through the connecting block 607. The clamping plate 608 deflects inward under the limiting action of the limiting fixing rod 610, causing the abutting block 609 to be inserted directly below the connecting platform 611. At the same time, the bottom of the limiting fixing rod 610 abuts against the inner bottom wall of the connecting pipe 606, so that the connecting platform 611 moves upward. The connecting platform 611 deflects through the first deflecting plate 701. Under the limiting action of the second deflecting plate 704, the first deflecting plate 701 drives the telescopic sleeve 702 to axially slide relative to the fixed block 703. At the same time, the connecting platform 611 drives the piston rod 706 to move upward, causing the hydraulic oil in the oil storage pipe 707 to enter the extraction pipe 705. The piston block 708 moves downward under the pressure and compresses the return spring.

[0048] S3: When the telescopic sleeve 702 contracts along the fixed block 703, it drives the grasping block 801 to contract inward, so that the inner side wall of the grasping block 801 abuts against the outer wall of the equipment. When the telescopic sleeve 702 slides on the outer wall of the fixed block 703, the through rod will extend through the through hole and abut against the outer wall of the rotating block 803. After being pushed, the rotating block 803 deflects around the support block 802 as the axis. The rotating block 803 pushes the grasping claw 804 to extend from the grasping block 801 to the bottom of the equipment. When the rotating block 803 deflects, it pushes the jacking block 806 to move inward. The jacking block 806 pushes the deflecting block 805 to deflect out of the grasping block 801 and abut against the outer wall of the equipment. When the connecting platform 611 moves upward, it pulls the steel rope 904 upward. The upward movement of the steel rope 904 causes the deflecting between the hinge blocks 903, making the hinge blocks 903 deflect inward in an arc and fit against the outer wall of the equipment. At this time, the telescopic sleeve 702 stops sliding on the outer wall of the fixed block 703, and the first deflecting plate 701 and the second deflecting plate 704 stop moving. Thus, the fixed block 703 moves upward following the connecting platform 611, and the equipment is suspended.

10. A method for using a pumped storage power station equipment lifting device, using the pumped storage power station equipment lifting device according to any one of claims 1 to 9, characterized in that: The steps include: S1: The rotating platform (1) drives the cantilever (3) to move to the top of the equipment through the truss (2), and the suspension rope (5) is moved to the top of the equipment through the trolley (4) and the bottom of the connecting platform (710) is brought into contact with the top of the equipment. The connecting platform (710) gives the extraction tube (705) an upward push force, and the extraction tube (705) drives the piston rod (706) to move upward, so that the outer wall of the piston rod (706) is released from the rotation guide groove and unlocked. The length of the fixed tube (602) and the telescopic rod (603) is adjusted according to the length of the equipment, so that the grab block (801) is adapted to the length of the equipment. The grab block (801) also drives the telescopic sleeve to be extended and retracted. At the same time, the fixed block (703) drives the telescopic block (709) to be extended and retracted accordingly through the connecting platform (710); S2: The suspension rope (5) is rolled up. The suspension rope (5) gives an upward traction force to the lifting ring (601). The lifting ring (601) applies the force to the connecting rod (605) through the connecting block (604). The connecting rod (605) drives the connecting pipe (606) to move upward. The connecting pipe (606) drives the clamping plate (608) to move upward through the connecting block (607). The clamping plate (608) deflects inwards under the limiting action of the limiting fixing rod (610), so that the abutting block (609) is inserted directly below the connecting platform (611). At the same time, the limiting fixing rod (610) ) abuts against the inner bottom wall of the connecting tube (606), so that the connecting platform (611) moves upward, and the connecting platform (611) is deflected by the first deflection plate (701). Under the limiting action of the second deflection plate (704), the first deflection plate (701) drives the telescopic sleeve (702) to slide axially relative to the fixed block (703). At the same time, the connecting platform (611) drives the piston rod (706) to move upward, so that the hydraulic oil in the oil storage pipe (707) enters the extraction pipe (705). The piston block (708) moves downward under the action of pressure and compresses the return spring; S3: When the telescopic sleeve (702) contracts along the fixed block (703), it will drive the grabbing block (801) to contract inward, so that the inner wall of the grabbing block (801) abuts against the outer wall of the device. When the telescopic sleeve (702) slides on the outer wall of the fixed block (703), the penetration rod will extend through the penetration hole and abut against the outer wall of the rotating block (803). After receiving the driving force, the rotating block (803) will deflect around the supporting block (802) as the axis. The rotating block (803) will push the grabbing claw (804) to extend from the grabbing block (801) to the bottom of the device. When the rotating block (803) deflects, it will push the pushing block (806) to move inward, and the pushing block (806) will move inward. The moving block (806) pushes the deflection block (805) to deflect out from the grabbing block (801) and abut against the outer wall of the device. When the connecting platform (611) moves upward, it will pull the steel rope (904) to move upward. The upward movement of the steel rope (904) will pull the hinge blocks (903) to deflect, causing the hinge blocks (903) to deflect inward in an arc shape and fit against the outer wall of the device. At this time, the telescopic sleeve (702) stops sliding on the outer wall of the fixed block (703), and the first deflection plate (701) and the second deflection plate (704) stop moving, so that the fixed block (703) moves upward following the connecting platform (611), thereby suspending the device.
