Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figures 1 to 4 As shown, the utility model provides a device for unloading and lifting concrete precast parts at water conservancy construction sites, comprising a ring plate 1, with L-shaped support plates 20 fixed on both sides of the upper and lower side walls of the ring plate 1. An upper plate 9 is provided directly below the ring plate 1, and a movable mechanism is connected between the upper plate 9 and the ring plate 1. Side plates 22 are fixed on both sides of the upper plate 9, and sliding mechanisms are connected between the side plates 22 and the side walls of the ring plate 1. An electric hoist 10 is fixedly mounted on the bottom of the upper plate 9. The electric hoist 10 generally has a lifting capacity of 0.3 to 80 tons and a lifting height of 3 to 30 meters. It is composed of an electric motor, a transmission mechanism, and a drum or sprocket, and is divided into two types: a wire rope electric hoist and a chain electric hoist.

[0019] A support plate 14 is provided directly below the electric hoist 10, and a lower plate 11 is provided above the support plate 14. Side lower plates 13 are fixed on both sides of the two side walls of the lower plate 11, and support rods 15 are fixed between the four side lower plates 13 and the support plate 14. A collar 12 is fixed above the lower plate 11, and the collar 12 is connected to the electric hoist 10. By placing the precast concrete parts above the support plate 14, the support plate 14 can be driven to move horizontally through the moving mechanism. When the support plate 14 is separated from the frame, the support plate 14 can be driven to move up and down by controlling the electric hoist 10. When the support plate 14 contacts the ground, the precast concrete parts can be unloaded.

[0020] Among them, wheels 21 are fixed to the bottom of the four L-shaped support plates 20, and the wheels 21 can facilitate the movement of the device.

[0021] A transverse plate 7 is fixed between the two L-shaped support plates 20 , and a push handle 8 is fixed on one side of the transverse plate 7 . The device can be conveniently moved by pushing the push handle 8 .

[0022] Among them, the moving mechanism includes two bearings 6, a base plate 3, and a skateboard 2. The base plate 3 is fixed on one side below the annular plate 1. A motor 4 is installed above the base plate 3. The skateboard 2 is fixed above the upper plate 9, and the skateboard 2 is slidably arranged in the annular plate 1. The two bearings 6 are respectively fixed on the two side walls of the annular plate 1. A threaded rod 5 is connected to one of the bearings 6. One end of the threaded rod 5 passes through the skateboard 2 and the other bearing 6 and is connected to the output shaft of the motor 4. The threaded rod 5 and the skateboard 2 are connected by a thread. Starting the motor 4 can drive the threaded rod 5 to rotate. The rotation of the threaded rod 5 can drive the skateboard 2 to move in the annular plate 1. The movement of the skateboard 2 can drive the upper plate 9 to move, thereby driving the support plate 14 to move.

[0023] Among them, the sliding mechanism includes a side sliding groove 16 and a side slide 17. The side sliding groove 16 is opened on the side wall of the annular plate 1, and the side slide 17 is fixed on one side of the side plate 22. The side slide 17 is slidably set in the side sliding groove 16. Grooves 18 are opened on both sides of the side wall of the side slide 17, and balls 19 are rotatably connected in the groove 18. The side slide 17 is slidably set in the side sliding groove 16 to limit the sliding of the upper plate 9.

[0024] The working principle and usage process of the present invention are as follows: by placing the two L-shaped support plates 20 of the lifting equipment on both sides of the frame, the precast concrete parts are placed on the support plate 14, and by starting the motor 4, the support plate 14 can be driven to move horizontally. When the support plate 14 is separated from the frame, the support plate 14 can be driven to move up and down by controlling the electric hoist 10. When the support plate 14 contacts the ground, the precast concrete parts can be unloaded, thereby saving the work intensity and time of the staff.
