[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0039] Reference Figure 1-3 The utility model provides an embodiment: a lifting and hoisting device, including a counterweight box 1, a first motor 2 is fixedly connected to the rear side of the counterweight box 1, a bidirectional screw rod 3 is fixedly connected to the output end of the first motor 2, a stabilizing column 4 is fixedly connected to the front and rear sides of the inner wall of the counterweight box 1, a threaded sleeve 5 is threadedly connected to the front and rear sides of the outer wall of the bidirectional screw rod 3, a support rod 6 is rotatably connected to the bottom of the threaded sleeve 5, and a sliding block 7 is rotatably connected to the far side of the two support rods 6, and a plurality of ground rods 8 are fixedly connected to the bottom of the sliding block 7, and the ground rods 8 on both sides can maintain the stability of the counterweight box 1 after touching the ground, and the four corners of the bottom of the counterweight box 1 are rotatably connected to rotating wheels 9, and a mounting block 11 is fixedly connected to the middle part of the outer wall of the bidirectional screw rod 3, and a lifting device body 12 is arranged on the top of the counterweight box 1, and the lifting device body 12 is the prior art. When using the present device, the power output by the first motor 2 can be used to drive the bidirectional screw rod 3 to rotate, thereby the threaded sleeve 5 threadedly connected to the bidirectional screw rod 3 drives the sliding block 7 connected to the support rod 6 to achieve lifting. As the two threaded sleeves 5 approach each other, the grounded rod 8 can be gradually lifted. After the rotating wheel 9 replaces the grounded rod 8 to be grounded, the staff can move the lifting device body 12 to move. After the grounded rod 8 is controlled to land in the reverse direction at the required lifting position, the moving function can be achieved. Such a design can effectively improve the flexibility and practicality of the device, making it convenient for the staff to change the lifting position of the lifting device in time.
[0040] Reference Figure 4-5 A connecting rod 13 is provided at the right side of the bottom of the lifting device body 12, and the connecting rod 13 is specifically fixed to the end of the sling of the lifting device body 12. The bottom of the connecting rod 13 is fixedly connected to a carrying box 14, and the bottom of the inner wall of the carrying box 14 is fixedly connected to a second motor 15, and the output end of the second motor 15 is fixedly connected to a driving disk 16, and the bottom of the driving disk 16 is rotatably connected to a plurality of crank blocks 17. The crank blocks 17 are designed with a special shape, and can synchronously drive the displacement blocks 18 to move under the restriction of the limit grooves 21 during the process of being driven by the driving disk 16, so as to realize the clamping and fixing function. The top of the crank block 17 is rotatably connected to the displacement block 18, and the top of the displacement block 18 is fixedly connected to the clamping plate 19. A limiting plate 20 is fixedly connected to the middle part of the inner wall, and a plurality of limiting grooves 21 are opened on the top of the limiting plate 20. When in use, the staff only needs to place the required hoisting cargo in the middle part of the carrying box 14, and then drive the driving plate 16 to rotate through the second motor 15, thereby driving the plurality of crank blocks 17 to synchronously drive the displacement blocks 18 to limit the position according to the limiting groove 21, so that the cargo is clamped and fixed by the clamping plate 19. Such a design can ensure the safety of the lifting process without manual fixation, and effectively reduce the time required for lifting and fixing, thereby improving the lifting efficiency.
[0041] Reference Figure 2-3 The bidirectional screw rod 3 is rotatably connected to both sides of the outer wall of the stabilizing column 4, thereby improving the stability of both sides of the bidirectional screw rod 33 during its rotation.
[0042] Reference Figure 2-3 The sliding block 7 is slidably connected to the outer wall of the stabilizing column 4, and the stabilizing column 4 passes through the sliding block 7 and is fixedly connected to the front and rear bottom sides of the inner wall of the counterweight box 1. By fixing the position of the stabilizing column 4, it is ensured that the sliding block 7 drives the landing rod 8 to move vertically up and down.
[0043] The mounting block 11 is located between the two threaded sleeves 5 . The design of the mounting block 11 limits the shortest travel of the threaded sleeves 5 to avoid collision.
[0044] Reference Figure 4-5 The displacement block 18 is slidably connected to the inner wall of the limiting groove 21, driving the disk 16 to rotate and be connected to the bottom of the limiting plate 20. Through the shape design of the limiting groove 21, the moving stroke of the clamping plate 19 can be fixed, so that the clamping plates 19 can be close to each other to achieve clamping and fixing; the crank block 17 slides and abuts against the bottom of the inner wall of the carrying box 14, increasing the stability of the crank block 17 during movement.
[0045] Reference Figure 2 A counterweight block is arranged on the top of the limit block 10 to improve the overall stability during lifting and moving.
[0046] Working principle: When the staff uses this kind of lifting and hoisting device, if it is necessary to move the position of the lifting and hoisting device, they can turn on the first motor 2, and the output power of the first motor 2 drives the bidirectional screw 3 to rotate, so that the threaded sleeve 5 threadedly connected to the bidirectional screw 3 drives the sliding block 7 connected to the support rod 6 to achieve lifting. As the two threaded sleeves 5 get closer, the grounding rod 8 in the grounded state can be gradually lifted. After the rotating wheel 9 replaces the grounding rod 8 to ground, the staff can move the lifting device body 12 to move. After the grounding rod 8 is controlled to land in the reverse direction at the required lifting position, the moving function can be realized. After the lifting device body 12 completes the position change, the staff only needs to place the required lifting goods in the middle of the carrying box 14, and then drive the driving plate 16 to rotate through the second motor 15, thereby driving multiple crank blocks 17 to synchronously drive the displacement block 18 to limit the position according to the limit groove 21, so that the goods are clamped and fixed by the clamping plate 19. Through such a design, the safety of the lifting process can be ensured without manual fixation, and the time required for lifting and fixing can be effectively reduced, thereby improving the lifting efficiency.
