Description

Technical Field

[0001] This utility model relates to the field of wall hoisting protection technology, specifically a safety protection device for the hoisting of prefabricated building walls. Background Technology

[0002] In the construction of prefabricated buildings, wall hoisting is one of the core processes, directly affecting construction progress, quality, and operational safety. Prefabricated walls are mostly precast components, large in size and heavy in weight. Hoisting requires the use of cranes and lifting equipment to complete the transfer and installation. To prevent safety accidents and component damage caused by wall falling during hoisting, corresponding safety protection equipment is usually configured to assist in the operation. The protective performance and adaptability of this equipment have a significant impact on the overall construction effect.

[0003] Currently, existing protective equipment has limited protective effects. During use, it easily interferes with the operation of the lifting equipment clamping the wall, affecting the smooth progress of the clamping operation, reducing the efficiency of hoisting construction, and most equipment cannot flexibly adjust the protective parameters, making it difficult to adapt to different wall specifications. Its versatility and adaptability are poor, and its application scope is limited. Furthermore, it lacks effective buffering and anti-secondary accident structures, making it difficult to effectively weaken the impact force when the wall falls. This can easily lead to wall damage, increase material consumption and rework costs, and cannot prevent the instantaneous tensile force generated by the wall falling from causing the lifting cable to break, which can easily cause secondary safety accidents. It cannot fully guarantee the personal safety of construction personnel, and its overall stability and reliability are insufficient.

[0004] Therefore, we propose a safety protection device for the hoisting of prefabricated building walls to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a safety protection device for the hoisting of prefabricated building walls, in order to solve the problems mentioned in the background art, such as poor protection effect of existing equipment, easy interference with the operation of the hoisting tool to clamp the wall, affecting the smooth progress of the clamping operation, reducing hoisting construction efficiency, difficulty in adapting to different specifications of walls, poor versatility and adaptability, and difficulty in effectively weakening the impact force when the wall falls, which can easily lead to wall damage, increase material consumption and rework costs, and cannot avoid the instantaneous tensile force generated by the wall falling causing the hoisting cable to break, which can easily cause secondary safety accidents, and cannot fully protect the personal safety of construction personnel, and the overall stability and reliability are insufficient.

[0022] 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.

[0023] Example: This example aims to address the safety hazards, reduced safety, increased cost, and insufficient protective compatibility issues arising from the easy detachment of walls from the lifting equipment during the hoisting process of prefabricated building walls. Please refer to [link / reference]. Figure 1 - Figure 6 A safety protection device for hoisting prefabricated building walls includes a sling 1, a base plate 2 fixed to the bottom surface of the sling 1, a protective component 3 and a lifting device 4 installed on the bottom surface of the base plate 2, the protective component 3 including two sets of support rods 36 symmetrically fixed to the outer wall of the base plate 2, a gear 37 rotating on the support rod 36, a crank 38 fixed to the surface of the gear 37, an arc groove 39 opened on the crank 38, a screw 311 slidably connected in the arc groove 39, an extension plate 310 fixedly connected to the side wall of the screw 311, a fixing plate 313 fixed to the end side of the extension plate 310, a telescopic rod 316 fixed to the bottom surface of the fixing plate 313, a support plate 315 fixed to the bottom surface of the telescopic rod 316, and a protective plate 317 fixed to the bottom surface of the support plate 315.

[0024] like Figure 4 As shown, a dual-axis cylinder 31 is symmetrically fixed on the top surface of the substrate 2. A connecting plate 32 is fixed to the output end of the dual-axis cylinder 31. A toothed plate 35 is fixed to the end side of the connecting plate 32. The toothed plate 35 meshes with the gear 37.

[0025] A limiting groove 34 is formed on the top surface of the substrate 2, and a limiting plate 33 is fixed on the bottom surface of the toothed plate 35. The limiting plate 33 is slidably connected to the limiting groove 34.

[0026] like Figure 5 As shown, a nut 312 is threaded onto the screw 311, and the nut 312 fits into the crank 38.

[0027] A screw 314 is installed on the internal thread of the fixing plate 313, and the screw 314 is rotatably connected to the support plate 315.

[0028] like Figure 6 As shown, multiple damping rods 318 are fixed to the side wall of the protective plate 317, and buffer plates 320 are fixed to the end of the multiple damping rods 318. Springs 319 are sleeved on the outer ring of each of the multiple damping rods 318. One end of the spring 319 is fixedly connected to the protective plate 317, and the other end of the spring 319 is fixedly connected to the buffer plate 320.

[0029] In this embodiment: When using the device, the sling 1 is connected to the crane, and the crane drives the entire device to descend, causing the lifting device 4 to descend and contact the wall. The lifting device 4's own drive structure drives the clamping components to move relative to each other, stably clamping the wall. The specific clamping drive method and clamping structure of the lifting device 4 are known technologies and will not be described in detail. During the hoisting process, due to factors such as a smooth wall surface, insufficient clamping force, or shaking during hoisting, the wall is prone to detaching from the lifting device 4. A slight mishap could cause it to fall, not only damaging the wall and increasing construction costs, but also potentially injuring workers below, significantly reducing construction safety.

[0030] The device can effectively avoid the above risks through the protective component 3. In the initial state, the toothed plate 35 and the gear 37 are in a pre-contact state, the protective plate 317 and the lifting device 4 are in a parallel retracted state, and the protective plate 317 is located on the outside of the lifting device 4, so it will not obstruct or interfere with the operation of the lifting device 4 clamping the wall, ensuring that the clamping operation is carried out smoothly.

[0031] like Figure 3 and Figure 4 As shown, after the lifting device 4 completes the clamping and fixing of the wall, the dual-axis cylinder 31 is activated. The output end of the dual-axis cylinder 31 drives the connecting plates 32 at both ends to move horizontally. The connecting plates 32 simultaneously drive the toothed plate 35 to move along the top surface of the base plate 2. At this time, the limiting plate 33 on the bottom surface of the toothed plate 35 slides in the limiting groove 34 of the base plate 2. The movement direction of the toothed plate 35 is limited by the cooperation between the limiting plate 33 and the limiting groove 34, so as to ensure that the toothed plate 35 moves smoothly and meshes precisely with the gear 37.

[0032] When the connecting plates 32 on both sides are driven to move by the dual-shaft cylinder 31, the right toothed plate 35 slides to the right, causing the corresponding gear 37 to rotate clockwise, and the left toothed plate 35 slides to the left, causing the corresponding gear 37 to rotate counterclockwise. The gear 37 synchronously drives the crank 38 fixed on the surface to rotate. When the crank 38 rotates, it drives the extension plate 310 to move through the sliding cooperation of the arc groove 39 and the screw 311. The screw 311 plays a limiting role in the relative position of the crank 38 and the extension plate 310. Rotating the nut 312 can adjust the tightness of the fit between the extension plate 310 and the crank 38 to prevent the two from shaking relative to each other. The extension plate 310 drives the fixed plate 313 to move synchronously. The fixed plate 313 drives the support plate 315 and the protective plate 317 to rotate and move synchronously through the telescopic rod 316, so that the protective plates 317 on both sides rotate synchronously from the outer position parallel to the lifting device 4 to the lower side wall. Finally, the two sets of protective plates 317 move to the lower position of the wall to form a U-shaped protective support structure, which plays a bottom protection role for the wall.

[0033] like Figure 5 and Figure 6 As shown, during the protection process, even if the wall separates from the hoist 4 and accidentally falls onto the buffer plate 320, the impact force received by the buffer plate 320 will be transmitted to the damping rod 318 and the spring 319. The spring 319 will first undergo elastic deformation to initially buffer and dissipate the impact force. At the same time, the damping rod 318 will play a damping and buffering role, slowing down the rebound speed of the spring 319 and further consuming the impact force. Through the synergistic effect of the two, the impact force of the wall falling is effectively weakened, avoiding the pulling force caused by the sudden fall due to gravity that could cause the hoist 1 to break. At the same time, it can also reduce the damage to the wall itself and ensure the personal safety of the personnel below.

[0034] Furthermore, during this process, the protection distance and height can be adjusted according to the specifications of the wall. When adjusting the protection distance, rotate nut 312 to loosen nut 312 from crank 38, push extension plate 310 to slide along the surface of crank 38, and screw 311 slides synchronously in arc groove 39. After extension plate 310 drives protection plate 317 to move to a suitable distance, tighten nut 312 again to fix the position of extension plate 310 and crank 38, thus completing the adjustment of protection distance.

[0035] When adjusting the protection height, rotate the screw 314 on the fixed plate 313. During the rotation of the screw 314, the support plate 315 moves up and down. The support plate 315 adapts to the height change through the extension and retraction of the telescopic rod 316, and synchronously drives the protective plate 317 to move up and down until the protective plate 317 is adjusted to a height that matches the bottom surface of the wall, so as to meet the protection requirements of different wall specifications and improve the versatility and adaptability of the device.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
