Description

Technical Field

[0001] This utility model relates to the field of prefabricated component technology, and in particular to a prefabricated component hoisting device. Background Technology

[0002] Precast components are produced in factories using standardized processes, resulting in stable quality and high precision. Therefore, on-site construction only requires hoisting and installation to complete the task. This model significantly shortens the construction cycle and improves efficiency. During on-site hoisting of precast components, existing BIM models can be used to simulate prefabricated building construction, allowing for real-time analysis and planning of the hoisting sequence. This ensures that precast components arrive at the work surface in the correct location, guaranteeing installation accuracy and construction quality.

[0003] In existing technologies, during the hoisting of precast tubular components, if the hoisting rope is too close to the edge of the component, it may cause horizontal tension on the hoisting point, increasing the risk of damage at the hoisting point. However, if it is too close to the center of gravity of the component, it may cause uneven force distribution at both ends. Therefore, it is necessary to repeatedly determine the position of the two hoisting ropes at the center of gravity during hoisting, and the hoisting ropes should pass through the inside of the precast tubular component. Since the hoisting points are located on the local outer walls at both ends, uneven force distribution is caused, which may easily lead to damage. Therefore, we propose a precast component hoisting device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a prefabricated component hoisting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precast component hoisting device includes a hoisting plate. Two U-shaped plates are slidably fitted onto the outer wall of the hoisting plate. A limiting mechanism is provided on the outer wall of each U-shaped plate. Hoisting rods are fixedly connected to the bottom of each of the two U-shaped plates. Support rods are fixedly connected to the bottom of each of the two hoisting rods. Elongated holes are opened on the outer walls of each of the two elongated holes. Screws are rotatably connected to the inner walls of each of the two elongated holes. Round blocks are threaded onto the outer walls of each of the two screws. Two T-shaped extrusion rods are fixedly connected to the outer walls of each of the four T-shaped extrusion rods. Arc-shaped inclined plates are slidably connected to one end of each of the four arc-shaped inclined plates. Arc-shaped hanging plates are fixedly connected to the outer walls of each of the four arc-shaped inclined plates. Two arc-shaped hanging plates are hinged together. Two telescopic rods are rotatably connected between the arc-shaped hanging plates and the support rods. Rubber pads are fixedly embedded in the outer walls of the arc-shaped hanging plates.

[0007] Preferably, the limiting mechanism includes two bolts, and the outer walls of the two U-shaped plates are provided with threaded holes. The inner walls of the two threaded holes are respectively threaded to the outer walls of the two bolts. The top of the lifting plate is provided with multiple insertion holes, and the U-shaped plates are fixed on the lifting plate by setting bolts.

[0008] Preferably, ribs are fixedly connected to the outer walls of both lifting rods, and the bottom of the two ribs are fixedly connected to the top of the two support rods respectively. The connection strength between the lifting rods and the support rods is increased by setting ribs.

[0009] Preferably, one end of each of the two screws is fixedly connected to a bearing, and the outer rings of the two bearings are fixedly connected to the inner walls of the two elongated holes respectively, so that the screws can rotate by means of the bearings.

[0010] Preferably, the outer walls of both support rods are provided with two strip grooves, and the inner walls of the four strip grooves are slidably connected to the outer walls of the four T-shaped extrusion rods respectively. The strip grooves are used to assist the T-shaped extrusion rods in linear sliding, and one end of the T-shaped extrusion rod is designed with a bevel.

[0011] Preferably, the outer wall of the support rod has a circular hole, the inner wall of the circular hole is rotatably connected to the outer wall of the screw, and a handwheel is fixedly connected to the other end of the screw. The screw thread helix angle is less than or equal to the friction angle, so that the screw has self-locking property. At the same time, a bolt can be added to the handwheel to fix the handwheel to the support rod after rotation.

[0012] Preferably, the outer walls of the four curved inclined panels are fitted with the same precast tubular component body, and the top of the hoisting plate is fixedly connected to two lifting rings, with lifting ropes fixedly installed on the outer walls of the two lifting rings.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This solution allows for the hoisting of precast tubular components of varying lengths by altering the relative position between two U-shaped plates. It utilizes support rods, screws, round blocks, T-shaped compression rods, curved inclined panels, curved hanging plates, telescopic rods, and rubber pads. The extension and retraction of the curved hanging plates at both ends causes the rubber pads to press against the inner wall of the precast tubular component, ensuring sufficient bearing area for precast tubular components of different sizes during hoisting. The overall operation is simple. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-4 As shown, a precast component hoisting device is disclosed, including a hoisting plate 1. Two U-shaped plates 2 are slidably sleeved on the outer wall of the hoisting plate 1. Hoisting rods 5 are fixedly connected to the bottom of the two U-shaped plates 2. Ribs 6 are fixedly connected to the outer wall of the two hoisting rods 5. The bottom of the two ribs 6 is fixedly connected to the top of the two support rods 7 respectively. The connection strength between the hoisting rods 5 and the support rods 7 is increased by the ribs 6.

[0023] The bottom of each of the two lifting rods 5 is fixedly connected to a support rod 7. The outer wall of each of the two support rods 7 is provided with an elongated hole. The inner wall of each of the two elongated holes is rotatably connected to a screw 8. One end of each of the two screws 8 is fixedly connected to a bearing. The outer rings of the two bearings are fixedly connected to the inner walls of the two elongated holes respectively.

[0024] Both screws 8 have a circular block 9 threaded onto their outer walls. Both circular blocks 9 have two T-shaped extrusion rods 10 fixedly connected to their outer walls. The circular blocks 9 and the two T-shaped extrusion rods 10 can move left and right through the screws 8. Both support rods 7 have two strip grooves on their outer walls. The inner walls of the four strip grooves are slidably connected to the outer walls of the four T-shaped extrusion rods 10.

[0025] One end of each of the four T-shaped extrusion rods 10 is slidably connected to an arc-shaped inclined panel 11. After the T-shaped extrusion rods 10 continuously extrude the arc-shaped inclined panel 11, the arc-shaped inclined panel 11 and the arc-shaped hanging plate 12 move upward. After the arc-shaped hanging plate 12 contacts the inner wall of the precast pipe component body 16 at the hinge position, the two arc-shaped hanging plates 12 rotate around the hinge position with the extrusion force. The outer walls of the four arc-shaped inclined panels 11 are all fixedly connected to the arc-shaped hanging plates 12. The two arc-shaped hanging plates 12 are hinged together. Two telescopic rods 13 are rotatably connected between the arc-shaped hanging plates 12 and the support rod 7. The telescopic rods 13 serve as connecting parts between the arc-shaped hanging plates 12 and the support rod 7 and rotate through the existing shaft.

[0026] The outer wall of the support rod 7 has a round hole, and the inner wall of the round hole is rotatably connected to the outer wall of the screw rod 8. The other end of the screw rod 8 is fixedly connected to a handwheel 14. The outer wall of the arc-shaped hanging plate 12 is fixedly inlaid with a rubber pad 15. The rubber pad 15 has a certain degree of flexibility and wear resistance. The outer walls of the four arc-shaped inclined panels 11 are fitted with the same precast pipe component body 16. The top of the hanging plate 1 is fixedly connected to two lifting rings.

[0027] The outer wall of the U-shaped plate 2 is provided with a limiting mechanism, which includes two bolts 3. The outer walls of the two U-shaped plates 2 are provided with threaded holes, and the inner walls of the two threaded holes are respectively threaded to the outer walls of the two bolts 3. The top of the lifting plate 1 is provided with multiple insertion holes 4.

[0028] Working Principle: In use, the existing hoisting equipment uses two hoisting ropes, one end of which is fixed to two fixed lifting rings. The hoisting plate 1 serves as the lifting end of the equipment. Rotating the two bolts 3 disengages their threaded ends from the two insertion holes 4, releasing the two retaining plates 2 from their fixed positions. This allows the retaining plates 2 to move, thereby moving the hoisting rod 5 and support rod 7. The two support rods 7 are positioned inside both ends of the precast pipe component body 16. Rotating the two bolts 3 again re-engages their threaded ends from the two insertion holes 4, fixing the two retaining plates 2 back onto the hoisting plate 1. Rotating the two handwheels 14 sequentially drives the two screws 8 to rotate, which in turn drives the two circular... Block 9 moves, and the movement of the two circular blocks 9 drives the four T-shaped extrusion rods 10 to move left and right. The left and right movement of the four T-shaped extrusion rods 10 drives the four arc-shaped inclined panels 11 to extend and retract. The main force is the extrusion force between the T-shaped extrusion rods 10 and the arc-shaped inclined panels 11, which causes the four arc-shaped hanging plates 12 to extend and retract in pairs through the hinged positions. At this time, the multiple telescopic rods 13 play a connecting role and rotate in the forward and backward direction. At the hinged position of the two arc-shaped hanging plates 12, they first contact the inner wall of the precast pipe component body 16. Then, the extension and retraction of the two ends of the arc-shaped hanging plates 12 causes the rubber pads 15 to be squeezed against the inner wall of the precast pipe component body 16. The operation is simple and reduces the danger.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
