Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting equipment, in particular to a prefabricated component hoisting device. Background Art

[0002] Prefabricated components are building elements prefabricated in factories or production facilities, including wall panels, floor slabs, columns, and beams. These components undergo rigorous quality control and testing during the production process, ensuring they meet high quality, precision, and efficiency requirements. At the construction site, these components are installed using hoisting devices, significantly shortening construction time and reducing labor costs. Traditional hoisting devices primarily work with cranes to lift prefabricated components. These devices are connected to the crane's boom via wire ropes to facilitate the installation of prefabricated components.

[0003] In the existing technology, construction workers are generally required to first release the fixation of the prefabricated components before unloading. Generally, at least two construction workers are required to lift the prefabricated components from both ends. This method of unloading is inefficient and requires the assistance of multiple people, which urgently needs to be improved. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the deficiencies in the prior art and provide a prefabricated component hoisting device. This application provides the following technical solutions:

[0005] It includes a frame, with splints provided on both sides of the frame, a rotating shaft provided on the splint, and the splint can rotate around the rotating shaft, a locking structure is provided between the splint and the frame, and the locking structure is used to lock the rotation angle of the splint, the rotating shaft is slidably provided on the frame, and a folding structure is provided on the frame, and the folding structure is connected to the splint, and is used to fold and pull the splint closer.

[0006] When hoisting the prefabricated components, the splint can be rotated around the rotation axis to vertical, and the splint can be locked by the locking structure to limit the rotation of the splint. Then, the two splints are pulled closer by the folding structure, and the two splints are close to each other to clamp the prefabricated components. When unloading the prefabricated components, the locking structure is released to release the restriction on the rotation of the splint, and then the splint is rotated around the rotation axis to horizontal. The prefabricated components can be pushed down from the top of the splint, and unloading is quick and convenient.

[0007] The frame body includes a horizontal frame, and sliding grooves are arranged on both sides of the horizontal frame. Slide blocks are slidably engaged in the sliding grooves, and the rotating shaft bearings are installed in the slide blocks.

[0008] A plurality of pin holes are arranged in a circular array around the rotating shaft on both sides of the splint. The locking structure includes a pin passed through the slider. The pin corresponds to the position of the pin hole. The pin can pass through the slider and be inserted into the pin hole. A tension spring is arranged between the pin and the slider. The tension spring is used to apply an elastic force to the pin close to the splint.

[0009] The folding structure includes a pull rod with one end hinged to the splint, and an adjustment block hinged to the other end of the pull rod. A strong action spring is provided between the adjustment block and the cross frame, and the strong action spring is used to apply an elastic force to the adjustment block away from the cross frame.

[0010] The strong action spring applies elastic force to the adjustment block, so that the adjustment block is horizontally mounted, and the pull rod is pulled to rotate, and the angle between the pull rods is reduced to pull the splints closer. The strong action spring has a large elastic force, and the clamping force is greater when the splints are close.

[0011] A bracket is provided at the bottom of the cross frame, a screw is fixed between the bracket and the cross frame, the adjustment block is passed through the screw, the strong action spring is sleeved on the screw, and the end of the screw away from the strong action spring is threadedly matched with a fastening nut.

[0012] By setting a screw and a fastening nut, the fastening nut can move up and down on the screw, abut against the adjustment block to limit the position, or by moving the fastening nut upward, the adjustment block is pushed upward to compress the strong action spring, which is used to hinder the movement of the adjustment block. When the clamping block is rotated, the elastic force generated by the strong action spring is prevented from causing the adjustment block to move, pulling the clamping block to move, and affecting the user's rotation of the clamping block.

[0013] The two side ends of the cross frame are connected by a U-shaped reinforcement rod arranged at the bottom; when the U-shaped reinforcement rod is provided, there is a movable space above the U-shaped reinforcement rod when the splint slides, which does not affect the movement of the splint. At the same time, the U-shaped reinforcement rod is connected to the cross frame, making the cross frame more integrated and more stable.

[0014] The ends of both sides of the cross frame are provided with notches, and connecting rods are provided in the notches. The two ends of the connecting rods are fixed to the side walls of the notches. The notches are provided, and connecting rods are provided in the notches to form a closed loop, which is used for the lifting rope or hook to be hooked with the connecting rod to lift the entire frame, and ensure that the upper surface of the cross frame is flat, so as to facilitate the pushing of prefabricated components on the cross frame.

[0015] The clamping plate is provided with a plurality of stripes perpendicular to the rotating shaft; when the clamping plate is horizontal, the prefabricated component can be pushed out along the direction of the stripes, and the friction force is smaller. When the clamping plate is vertical, the stripes are in contact with the prefabricated component, and when the prefabricated component moves in the direction perpendicular to the stripes, it acts as an obstacle, thereby increasing the clamping effect.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] The splint can rotate around the rotating axis and can be locked by a locking structure, and the splint can slide on the frame. When the splint is in a vertical state, the folding structure pulls the two splints closer, and the two splints are close to each other to clamp the prefabricated components. When unloading the prefabricated components, the locking structure is released and the splint is adjusted to a horizontal position. The prefabricated components can be pushed down from above the splint and the frame without lifting the prefabricated components. Unloading is more labor-saving, quick and convenient.

[0031] Please refer to Figure 1-7 As shown, this is a prefabricated component lifting device provided by the utility model

[0032] It includes a frame 1, with splints 2 provided on both sides of the frame 1, a rotating shaft 21 provided on the splint 2, and the splint 2 can rotate around the rotating shaft 21. A locking structure 4 is provided between the splint 2 and the frame 1, and the locking structure 4 is used to lock the rotation angle of the splint 2. The rotating shaft 21 is slidably provided on the frame 1, and a folding structure 3 is provided on the frame 1. The folding structure 3 is connected to the splint 2 and is used to fold and pull the splint 2 closer.

[0033] The frame body 1 includes a horizontal frame 11 , and slide grooves 111 are provided on both sides of the horizontal frame 11 . Slide blocks 112 are slidably engaged in the slide grooves 111 , and the bearings of the rotating shaft 21 are installed in the slide blocks 112 .

[0034] A plurality of pin holes 22 are arranged in a circular array around the rotating shaft 21 on both sides of the splint 2. The locking structure 4 includes a latch 41 passed through the slider 112. The latch 41 corresponds to the position of the pin hole 22. The latch 41 can pass through the slider 112 and be inserted into the pin hole 22. A tension spring 42 is arranged between the latch 41 and the slider 112. The tension spring 42 is used to apply an elastic force to the latch 41 close to the splint 2.

[0035] The folding structure 3 includes a pull rod 31 hinged to the splint 2 at one end, and an adjustment block 32 hinged at the other end of the pull rod 31. A strong action spring 33 is arranged between the adjustment block 32 and the cross frame 11. The strong action spring 33 is used to apply an elastic force to the adjustment block 32 away from the cross frame 11.

[0036] A bracket 12 is provided at the bottom of the cross frame 11, and a screw 34 is fixed between the bracket 12 and the cross frame 11. The adjustment block 32 is passed through the screw 34, and the strong action spring 33 is sleeved on the screw 34. The end of the screw 34 away from the strong action spring 33 is threadedly fitted with a fastening nut 35.

[0037] The ends of both sides of the cross frame 11 are connected by a U-shaped reinforcement rod 113 provided at the bottom.

[0038] Notches 114 are provided at both ends of the cross frame 11 . Connecting rods 115 are provided in the notches 114 . Both ends of the connecting rods 115 are fixed to the side walls of the notches 114 .

[0039] The splint 2 is provided with a plurality of stripes 23 perpendicular to the rotation axis 21 .

[0040] During specific implementation, when the splint 2 is in a horizontal state, the prefabricated component is placed on the cross frame 11, and then the knob tightening nut 35 is turned to make the tightening nut 35 move upward along the screw rod 34, pushing the adjustment block 32 to move upward. At this time, the angle between the pull rods 31 becomes larger, pushing the splint 2, and the slider 112 slides in the slide groove 111 to make the splints 2 move away from each other. When the position of the rotating shaft 21 on the splint 2 is located outside the prefabricated component, stop tightening the knob nut 35, pull the pin 41, and move the pin 41 out of the originally inserted pin hole 22, and flip the splint 2. , the splint 2 rotates around the rotating shaft 21 to vertical, and then the pin 41 is loosened. The pin 41 is inserted into the other pin holes 22 on the side of the splint 2 under the action of the tension spring 42, limiting the rotation of the splint 2, and then the knob is tightened to tighten the nut 35, so that the tightening nut 35 moves downward along the screw rod 34. The elastic force of the strong action spring 33 pushes the adjustment block 32 to move downward, and the angle between the pull rods 31 becomes smaller, pulling the splint 2 closer to clamp the prefabricated component; then use the wire rope to connect it to the connecting rod 115, and use the lifting equipment to lift the frame 1 and the prefabricated component.

[0041] When unloading, the knob can be turned to tighten the nut 35, so that the tightening nut 35 moves upward along the screw rod 34, pushing the adjustment block 32 to move upward, so that the splints 2 move away from each other, and then the pin 41 is pulled and the splint 2 is flipped to rotate the splint 2 to the horizontal state and then the pin 41 is released. The pin 41 is inserted into the pin hole 22 on the side of the splint 2 and locked. At this time, the splint 2 is in the horizontal state, and the prefabricated component can be moved down from the horizontal frame 11.

[0042] During the actual unloading operation, there is a more labor-saving operation method. First, turn the knob to tighten the nut 35 so that it abuts against the lower part of the adjustment block 32. At this time, the adjustment block 32 is fixed and there is no need to push the adjustment block 32 to move upward. At this time, you can pull the pin 41 and flip the splint 2. Since the adjustment block 32 is fixed, when the splint 2 is flipped to the horizontal, the slider 112 will first slide outward and then slide inward, and will not collide with the prefabricated components. Furthermore, the upper part of the cross frame 11 is wider, and there are U-shaped reinforcement rods 113 on both sides. The bottom of the bracket 12 is narrower, and one side of the cross frame 11 can be lifted to tilt the frame body 1, so that the prefabricated components slide down on the cross frame 11.

[0043] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
