[0002] With the continuous development of my country's water conservancy infrastructure construction, the safety of dangerous reservoirs has received increasing attention. Reservoir sluices, as an important part of the reservoir, undertake multiple functions such as flood control, drainage, and water supply. However, in the long-term operation process, due to the influence of various natural and man-made factors, some sluices have serious diseases and safety hazards and need to be de-risked and reinforced.

[0003] During the process of removing hazards and reinforcing dangerous reservoirs, when the gate hoist is damaged and cannot be used, it needs to be replaced. After the old gate hoist is dismantled, the new gate hoist is transported by a lifting device and installed manually.

At the same time, when the lifting device fails and causes the gate hoist to fall, it will not only damage the new gate hoist, but also may accidentally injure surrounding personnel. For this reason, a water gate dismantling and repairing device with a protective effect for removing hazards in dangerous reservoirs is designed. Summary of the invention

[0022] In this embodiment, the bottom of the rotating rod 601 is fixedly connected to a U-shaped bottom plate 6, and sliding rods 603 are fixedly connected between the two ends of the U-shaped bottom plate 6.

The two sides of the bottom of the two L-shaped clamping plates 604 are close to each other. An arc groove is opened, and an arc rubber pad 605 is fixedly connected in each arc groove.

[0023] In this embodiment, a same bidirectional screw rod 602 is rotatably connected between the middle parts of the two ends of the U-shaped bottom plate 6, and both ends of the bidirectional screw rod 602 are threaded through the L-shaped clamping plate 604, and a screw nut compatible with the bidirectional screw rod 602 is fixedly sleeved at the middle of the top of each L-shaped clamping plate 604, one end of the bidirectional screw rod 602 passes through the U-shaped bottom plate 6 and is fixedly connected to a second worm gear 607, and two mounting plates 606 are fixedly connected to the outside of the U-shaped bottom plate 6 near the second worm gear 607, and a second worm 608 is rotatably connected between the two mounting plates 606. The cooperation between the second worm 608 and the second worm gear 607 ensures that the L-shaped clamping plate 604 is in a stable state when fixing the gate opening and closing machine, so that the gate opening and closing machine will not loosen and fall, and the second worm 608 is meshed with the second worm gear 607, and a second motor 609 is fixedly connected to the outside of one of the mounting plates 606, and the output end of the second motor 609 passes through the mounting plate 606 and is fixedly connected to one end of the second worm 608.

[0024] In this embodiment, universal wheels 101 are fixedly connected to the four corners of the bottom of the base plate 1, a push handle 2 is fixedly connected to the end of the top of the base plate 1 away from the groove 102, a protective plate 201 is fixedly connected to the top of the base plate 1 near the push handle 2, and an observation hole 202 is provided on the top of the protective plate 201. The protective plate 201 can protect the staff at the push handle 2 to ensure that the staff at this location are not injured.

[0025] In this embodiment, two side plates 4 are fixedly connected to the top of the base plate 1 near the protective plate 201, and the same winding roller 402 is rotatably connected between the two side plates 4. A steel wire rope 404 is fixedly connected to the winding roller 402, and the other end of the steel wire rope 404 is wrapped around the fixed pulley 303 and fixedly connected to the top of the U-shaped plate 502.

[0026] In this embodiment, a torque motor 401 is fixedly connected to the outer side of one of the side plates 4. The lifting and lowering of the lifting plate 5 is controlled by the forward and reverse rotation of the torque motor 401, and the output end of the torque motor 401 passes through the side plate 4 and is fixedly connected to one end of the winding roller 402.

[0027] Working principle: When the device is in use, the gate hoist to be disassembled is located on the inner side through the movement of the equipment, and the torque motor 401 is started to release the wire rope 404, so that the lifting plate 5 is lowered until the two L-shaped clamping plates 604 are close to the gate hoist, and the second motor 609 is started to make the second worm 608 drive the second worm wheel 607 to rotate, so that the two-way screw rod 602 rotates, so that the two L-shaped clamping plates 604 are close to each other until the gate hoist is fixed, and the torque motor 401 is started to reverse, so that the lifting plate 5 brings the gate hoist up, so that the damaged gate hoist is transported away. When installing a new gate hoist, the L-shaped clamping plate 609 is used to fix the gate hoist. 04 After the gate hoist is fixed, the equipment is moved so that the gate hoist reaches the threaded rod at the top of the gate, so that the gate hoist is aligned with the threaded rod, and the torque motor 401 is gradually released, and the first motor 506 is started at the same time, so that the first worm 505 rotates with the first worm wheel 503, and then the rotating rod 601 rotates with the U-shaped bottom plate 6 and the gate hoist, so that the gate hoist rotates and gradually descends through the threaded rod of the gate until the gate hoist descends to the bottom, thereby realizing the installation of the gate hoist. During the process, since the lifting plate 5 moves up and down along the guide rod 304 and will not deviate, there is no need to manually swing the gate hoist during the lifting and lowering process of the gate hoist, thereby avoiding manual contact with the heavier hoist. At the same time, the first motor 506 drives the gate hoist and the like to rotate, and also avoids manual work approaching the gate hoist that needs to be installed, so that the gate hoist rotates and contacts and rotates with the threaded rod at the top of the gate. At the same time, the setting of the protective plate 201 realizes the protection of manual work, and the wire rope 404 breaks, which causes accidental injury to the staff at the push handle 2. At the same time, the setting of the protective mechanism 7 makes the lifting plate 5 not work when it is stably and slowly lifted. When the wire rope 404 breaks or the torque motor 401 fails, the lifting plate 5 will quickly descend with the gate hoist. At this time, due to the sliding of the connecting rod 501 in the spiral groove 702, the two round rods 701 rotate rapidly, and under the action of centrifugal force , the swing rod 709 rotates accordingly, causing the swing rod 709 to slide along the spiral inclined hole 707, and the outer end of the swing rod 709 gradually approaches the inclined clamping tooth 704, so that the round rod 701 is stuck and can no longer rotate. At the same time, the lifting plate 5 no longer brings the gate hoist down, ensuring the safety of the gate hoist and protecting the surrounding staff. When the lifting plate 5 is slowly lifted, under the action of gravity, the swing rod 709 is located at the bottom of the spiral inclined hole 707, and the swing rod 709 does not contact the inclined clamping tooth 704. When the round table 705 rotates rapidly, under the action of centrifugal force, the swing rod 709 rotates toward the outside, and then slides up along the spiral inclined hole 707 to achieve work.
