Abstract
Description
Technical Field
[0001] This utility model relates to a wall hoisting mechanism, specifically an intelligent construction wall hoisting mechanism, belonging to the field of building construction equipment technology. Background Technology
[0002] In the process of prefabricated intelligent construction, the hoisting and installation of walls is a crucial step, and its efficiency and safety directly affect the overall construction progress and project quality. Currently, the industry generally uses tower cranes in conjunction with hoisting mechanisms to complete wall hoisting operations: after the hooks on the hoisting mechanism are precisely connected to the pre-set connectors on the wall, the tower crane moves the wall by pulling the hoisting mechanism, thereby realizing the transfer and installation of the wall.
[0003] However, in actual hoisting operations, the lack of an effective buffer device creates a series of problems that urgently need to be addressed when the hoisting mechanism lifts the wall. From an equipment perspective, the instantaneous tensile impact causes the hooks, ropes, and other components of the hoisting mechanism to bear a large load. Over time, this can easily lead to accelerated wear and fatigue fracture of these components, shortening the service life of the hoisting mechanism and increasing equipment maintenance costs and replacement frequency. From the perspective of the wall itself, this unbuffered tensile force can subject the wall to severe stress. For brittle components such as prefabricated assembled walls, this can easily cause cracks, edge damage, and other injuries, and in severe cases, even lead to the wall being scrapped, resulting in material waste and construction delays. Utility Model Content
[0004] The purpose of this utility model is to provide an intelligent wall hoisting mechanism for construction in order to solve the above problems. It can buffer when lifting the wall, making the hoisting process more stable and avoiding damage to the wall due to excessive instantaneous tension, thereby improving the safety of use and reducing the probability of damage to the hoisting mechanism, thus reducing the maintenance cost of the equipment.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a wall hoisting mechanism for intelligent construction, comprising a crossbeam, a buffer structure on the crossbeam, the buffer structure including a support base and connecting columns, a support base fixedly connected to the top center of the crossbeam, two connecting columns fixedly connected to the support base, a sliding sleeve slidably connected to the connecting columns, a buffer spring sleeved on the outside of the connecting columns, a retaining ring threadedly connected to the connecting columns, one end of the buffer spring abutting against the connecting column, the other end of the buffer spring abutting against the retaining ring, two connecting blocks fixedly connected to both sides of the sliding sleeve, a common pull ring fixedly connected to the two connecting blocks, the pull ring passing through one end of a first steel wire rope, the other end of the first steel wire rope passing through and installed with a hook, two first guide wheels rotatably connected to the crossbeam, a first steel wire rope wound on the first guide wheels, and a limit ring fixedly connected to the connecting columns.
[0006] Preferably, the two limiting rings are symmetrically distributed about the middle of the support base, and the two connecting blocks are symmetrically distributed about the middle of the sliding sleeve.
[0007] Preferably, the outer side of the retaining ring is provided with a plurality of grooves, and the plurality of grooves are distributed in a circumferential array about the middle of the retaining ring.
[0008] Preferably, two connecting seats are fixedly connected to the top side of the crossbeam. The connecting seats pass through one end of the second steel wire rope, and the other ends of the two second steel wire ropes are installed through the same lifting ring.
[0009] Preferably, the two connecting seats are symmetrically distributed about the middle of the crossbeam, and the lifting ring has an overall triangular structure.
[0010] Preferably, two second guide wheels are rotatably connected to the crossbeam, and the second guide wheels abut against the adjacent first wire rope.
[0011] Preferably, the hook is provided with a limiting structure, the limiting structure including a rotating block and a spring piece, the rotating block is rotatably connected to the hook, a stop block is fixedly connected to the hook, one side of the rotating block abuts against the stop block, a stop bar is rotatably connected to the hook, a torsion spring is fixedly connected between the stop bar and the hook, and the other side of the rotating block abuts against the stop bar.
[0012] Preferably, a spring sheet is fixedly connected to the stop block, and the spring sheet abuts against the rotating block.
[0013] Preferably, the overall cross-section of the rotating block is a "√" shape, the cross-section of the rotating block near the stop bar is a trapezoidal shape, and the hook is provided with an opening.
[0014] The beneficial effects of this utility model are as follows: When the first wire rope generates tension during lifting, it applies the tension to the pull ring. The pull ring then applies the tension to the sliding sleeve through two connecting blocks. After being subjected to tension, the sliding sleeve slides on the connecting column. At this time, the buffer spring contracts. As the buffer spring gradually contracts, the tension applied by the hook to the wall connector slowly increases, avoiding damage to the wall due to excessive instantaneous tension, thereby improving the safety of use. At the same time, it avoids damage to the lifting components inside the lifting mechanism from bearing large loads during lifting for a long time, thus reducing the probability of damage to the lifting mechanism and reducing the maintenance cost of the equipment. After the sliding sleeve slides a certain distance on the connecting column, one end will abut against the limit ring, thus avoiding damage to the buffer spring caused by excessive compression over a long period of time. Furthermore, the buffer spring can be replaced by unscrewing the retaining ring from the connecting column, thus facilitating the inspection and maintenance of the buffer spring while ensuring its buffering effect.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 As shown, a smart construction wall hoisting mechanism includes a crossbeam 1 with a buffer structure 2. The buffer structure 2 includes a support base 201 and connecting columns 202. The support base 201 is fixedly connected to the middle of the top side of the crossbeam 1. Two connecting columns 202 are fixedly connected to the support base 201. A sliding sleeve 203 is slidably connected to the connecting column 202. A buffer spring 204 is sleeved on the outside of the connecting column 202. A retaining ring 205 is threadedly connected to the connecting column 202. One end of the buffer spring 204 abuts against... The other end of the buffer spring 204 abuts against the retaining ring 205, and two connecting blocks 207 are fixedly connected to both sides of the sliding sleeve 203. The same pull ring 208 is fixedly connected to the two connecting blocks 207. The pull ring 208 passes through one end of the first steel wire rope 3. The other end of the first steel wire rope 3 is installed with a hook 4. Two first guide wheels 6 are rotatably connected to the crossbeam 1. The first steel wire rope 3 is wound on the first guide wheels 6. A limit ring 209 is fixedly connected to the connecting column 202.
[0022] As a technical optimization of this utility model, the two limiting rings 209 are symmetrically distributed about the middle of the support base 201, so that the two sliding sleeves 203 can stop after moving the same distance, and the two connecting blocks 207 are symmetrically distributed about the middle of the sliding sleeves 203.
[0023] As a technical optimization of this utility model, the outer side of the retaining ring 205 is provided with multiple grooves 206. By setting the grooves 206, it is convenient to insert the shaft into its interior and rotate it off the connecting post 202. The multiple grooves 206 are arranged in a circumferential array about the center of the retaining ring 205. Therefore, when the retaining ring 205 rotates at a certain angle, it is only necessary to insert the shaft into the interior of different grooves 206 to achieve the goal of rotating the retaining ring 205 in one position, thereby improving the convenience of operation.
[0024] As a technical optimization of this utility model, two connecting seats 8 are fixedly connected to the top side of the crossbeam 1. The two connecting seats 8 are symmetrically distributed about the middle of the crossbeam 1. The connecting seats 8 pass through one end of the second steel wire rope 9. The two second steel wire ropes 9 and the crossbeam 1 form a triangular structure, which can improve the hoisting process. The other end of the two second steel wire ropes 9 is installed through the same lifting ring 10. The lifting ring 10 is triangular in shape and can be connected to the tower crane.
[0025] As a technical optimization of this utility model, two second guide wheels 7 are rotatably connected on the crossbeam 1. The second guide wheels 7 abut against the adjacent first wire rope 3, so they can rotate when the first wire rope 3 moves, thereby reducing the degree of friction damage to the first wire rope 3.
[0026] As a technical optimization of this utility model, the hook 4 is provided with a limiting structure 5, which includes a rotating block 501 and a spring piece 502. The rotating block 501 is rotatably connected to the hook 4, and the rotating block 501 can block the stop rod 504. The stop block 503 is fixedly connected to the hook 4, and the stop block 503 can block and limit the rotating block 501. One side of the rotating block 501 is in contact with the stop block 503. The stop rod 504 is rotatably connected to the hook 4, and a torsion spring 505 is fixedly connected between the stop rod 504 and the hook 4. The torsion spring 505 can make the stop rod 504 always in contact with the rotating block 501.
[0027] As a technical optimization of this utility model, a spring piece 502 is fixedly connected to the stop block 503. The spring piece 502 can keep the rotating block 501 in contact with the stop block 503 without the action of external force. The spring piece 502 and the rotating block 501 are in contact.
[0028] As a technical optimization of this utility model, the overall cross-section of the rotating block 501 is a "√" shaped structure, and the cross-section of the rotating block 501 near the stop bar 504 is a trapezoidal structure. Therefore, when the stop bar 504 rotates from the outside of the hook 4 toward the inside of the hook 4, it can automatically abut against the rotating block 501 and rotate. The hook 4 is provided with an opening 506, so that the rotating block 501 can rotate inside the opening 506.
[0029] In use, this utility model allows the lifting ring 10 to be connected to a tower crane, enabling the lifting ring 10 to be moved. The lifting ring 10 drives the crossbeam 1 to move via two second steel wire ropes 9. Since the two second steel wire ropes 9 and the crossbeam 1 form a triangular structure, stability during movement is improved. When the hook 4 moves with the crossbeam 1 to the vicinity of the pre-installed connector on the wall, it can be connected to the pre-installed connector. During hook 4 installation, the connector will abut against the stop bar 504 and move towards the inside of the hook 4. When the connector is inside the hook 4, the stop bar 504 will reset under the action of the torsion spring 505 and engage with the rotating block 501. During lifting, the stop bar 504 provides resistance, preventing the hook 4 from detaching from the connector. When the first wire rope 3 generates tension during lifting, this tension is applied to the pull ring 208. The pull ring 208 then transfers the tension to the sliding sleeve 203 via two connecting blocks 207. Under this tension, the sliding sleeve 203 slides on the connecting column 202. At this time, the buffer spring 204 contracts. As the buffer spring 204 gradually contracts, the tension applied by the hook 4 to the wall connector slowly increases, thus preventing damage to the wall due to excessive instantaneous tension and improving safety. This also prevents prolonged damage to the lifting components inside the lifting mechanism. The sliding sleeve 203 is designed to withstand heavy loads during lifting, thus reducing the likelihood of damage to the lifting mechanism and lowering maintenance costs. After sliding a certain distance on the connecting column 202, one end of the sliding sleeve 203 will abut against the limiting ring 209, preventing excessive compression of the buffer spring 204 and subsequent damage. The buffer spring 204 can be replaced by inserting the shaft into the groove 206 and then unscrewing the retaining ring 205 from the connecting column 202 by hand. This facilitates maintenance and repair of the buffer spring 204 while ensuring its cushioning effect. During unhooking, the rotating block 501 can be pushed... When the rotating block 501 rotates, the spring 502 will be compressed and undergo elastic deformation. While the rotating block 501 is moving, it will resist the rotation of the stop bar 504. When the rotating block 501 rotates to a certain angle, it will disengage from the stop block 503. At this time, under the action of the torsion spring 505, the stop bar 504 will move towards the outside of the hook 4. Since the stop bar 504 does not resist the connecting part at this time, it is convenient to disengage the connecting part. At the same time, since the stop bar 504 rotates towards the outside of the hook 4, it can avoid the situation where the connecting part resists the stop bar 504 when rotating inward as in the traditional way, and the position of the hook 4 needs to be adjusted. This improves the convenience of disengagement operation.
