TECHNICAL FIELD

[0001] The utility model relates to hoisting equipment technical field especially relates to a prefabricated building modularization quick hoisting equipment. BACKGROUND

[0002] At the moment of the vigorous development of prefabricated building, construction efficiency and quality become the industry focus. Prefabricated building is prefabricated by building module in factory, then transported to construction site for assembly, which greatly shortens construction period, reduces on-site wet operation and reduces the influence of construction on environment, and meets the development trend of green building. In prefabricated building construction, hoisting operation is a key link, and its efficiency and safety directly affect the whole project progress and quality.

[0003] At present, the traditional prefabricated building hoisting equipment has many problems in practical application. When clamping prefabricated building boards of different sizes, the clamping structure of the existing equipment often lacks flexibility and adjustability. The clamping body of most equipment is fixed, and cannot be quickly adjusted according to the change of building board size. Therefore, the construction personnel need to spend a lot of time and effort to manually adjust at the construction site, and even need to replace clamps of different specifications, which leads to low construction efficiency. Although some equipment has certain adjustment function, the adjustment range is limited, and it is difficult to meet the diversified building board size requirements. In view of the technical problems, the present application provides a prefabricated building modularization quick hoisting equipment. UTILITY MODEL CONTENTS

[0004] The utility model discloses a prefabricated building modularization quick hoisting equipment, which adjusts the distance between the two blocking frames by pulling the fixing block, and changes the spacing of the second clamping tooth. At the same time, the sliding of the sliding block on the guide rod and the connecting structure of the connecting rod and the sliding frame enable the first clamping tooth to adjust the position flexibly. No matter how the length and width of the building board change, the first clamping tooth can be moved to the appropriate position and clamped stably.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A prefabricated building modularization quick hoisting equipment, comprising a cross beam, two sliding blocks are connected to the inner wall of the cross beam through guide rods, and two lifting rings are connected to the top of the two sliding blocks through chains. The cross beam is fixedly connected with support beams at the front and rear ends, and the bottom of each support beam is slidingly connected with a sliding frame. The bottom of each sliding frame is fixedly connected with a first clamping tooth. The bottom of the left sliding block is connected with the left sliding frame through a connecting rod. The inner wall of the left support beam is connected with two fixing blocks through a spring assembly. The inner wall of the rear fixing block is connected with a lead screw through a threaded sleeve, and the outer wall of the lead screw is rotatably connected with a limiting assembly.

[0007] Furthermore, the elastic component includes two slide rods located on the inner wall of the left support beam. Both slide rods are fixedly connected to the right end of the fixing block. Springs are provided on the outer walls of both slide rods, and fixing plates are fixedly connected to the right side of the outer walls of both slide rods.

[0008] Furthermore, one end of each of the two springs is connected to the support beam, and the other end of each of the two springs is connected to the fixing plate.

[0009] Furthermore, the limiting component includes a blocking frame located on the outer wall of the lead screw, and a clamping tooth is fixedly connected to the bottom right end of the blocking frame.

[0010] Furthermore, a second guide rod is slidably connected to the inner wall of the front fixing block, and the second guide rod is fixedly connected to the inner wall of the blocking frame.

[0011] Furthermore, a knob is fixedly connected to the top of the lead screw, and the knob is rotatably connected to the top of the stop frame.

[0012] Furthermore, each of the two clamping teeth on the left side is slidably connected to a sliding rod.

[0013] Furthermore, a spring is provided on the outer wall of the guide rod, one end of the spring is connected to the slider, and the other end of the spring is connected to the crossbeam.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, when faced with prefabricated building panels of different sizes, construction workers can adjust the distance between the two blocking frames by pulling the fixing block, thereby changing the spacing of the clamping teeth and achieving initial positioning of building panels of different widths. Simultaneously, the sliding of the slider on the guide rod and the connection structure between the connecting rod and the sliding frame allow the clamping teeth to be flexibly adjusted in position. Regardless of changes in the length and width of the building panel, the clamping teeth can move to the appropriate position and stably clamp it, greatly improving the versatility of the equipment.

[0016] 2. In this utility model, before hoisting, the clamping teeth are adjusted to a suitable position to limit the prefabricated building panel. During the entire hoisting process, even if the building panel becomes unstable, the clamping teeth can firmly hold the side of the building panel, preventing it from slipping off the side, which greatly improves the safety of the hoisting operation and effectively avoids safety accidents and property losses caused by the slipping of the building panel.

[0023] 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.

[0024] Reference Figures 1-3 An embodiment of this utility model provides: a modular rapid hoisting equipment for prefabricated buildings, including a crossbeam 1, two sliders 4 connected to the inner wall of the crossbeam 1 by a guide rod 2, a lifting ring 6 connected to the top of each slider 4 by a chain 5, support beams 7 fixedly connected to both the front and rear ends of the crossbeam 1, sliding frames 8 slidably connected to the bottom ends of each support beam 7, and clamping teeth 9 fixedly connected to the bottom ends of each sliding frame 8, the bottom end of the left slider 4 connected to the left sliding frame 8 by a connecting rod 11, two fixing blocks 13 connected to the inner wall of the left support beam 7 by a sliding rod 2 12, a lead screw 16 connected to the inner wall of the rear fixing block 13 by a threaded sleeve, and a blocking frame 17 and clamping teeth 20 rotatably connected to the outer wall of the lead screw 16;

[0025] Specifically, the clamping tooth 9 is moved to the bottom of the prefabricated building panel, and then the crane is started. The crane lifts the hook upward, causing the lifting ring 6 to rise. The lifting ring 6 is connected to the slider 4 via the chain 5. Therefore, when the lifting ring 6 rises, the chain 5 will cause the slider 4 to slide on the guide rod 2. Since the bottom end of the left slider 4 is connected to the left sliding frame 8 via the connecting rod 11, the movement of the slider 4 will be transmitted to the sliding frame 8 through the connecting rod 11, causing the sliding frame 8 to slide downward on the support beam 7. The downward movement of the sliding frame 8 causes the clamping tooth 9, which is fixed at its bottom end, to gradually approach the prefabricated building panel. Ultimately, the building slab is clamped. During this process, to ensure equipment stability, construction workers need to continuously press the support beam 7 until the clamping teeth 9 firmly clamp the building slab before releasing their grip. The chain 5, as the transmission component connecting the lifting ring 6 and the slider 4, can reliably transmit the crane's pulling force, ensuring that the lifting ring 6's rising and falling movements can accurately drive the slider 4 to move, thus ensuring the smooth progress of the hoisting operation. The lifting ring 6, as the connection point between the equipment and the crane hook, directly bears the crane's pulling force, transmitting the crane's lifting force to the entire equipment.

[0026] Reference Figures 2-4 The two slide rods 12 located on the inner wall of the left support beam 7 are fixedly connected to the right end of the fixed block 13. The outer wall of each slide rod 12 is provided with a spring 14. The right side of the outer wall of each slide rod 12 is fixedly connected with a fixing plate 15. One end of each spring 14 is connected to the support beam 7, and the other end of each spring 14 is connected to the fixing plate 15. The blocking frame 17 located on the outer wall of the screw rod 16 has a clamping tooth 20 fixedly connected to the bottom side of the right end. The inner wall of the front fixed block 13 is slidably connected with a guide rod 19, which is fixedly connected to the inner wall of the blocking frame 17. The top of the screw rod 16 is fixedly connected with a knob 18, which is rotatably connected to the top of the blocking frame 17. The inner walls of the two clamping teeth 9 on the left are slidably connected with slide rods 10. The outer wall of the guide rod 2 is provided with a spring 3, one end of which is connected to the slider 4, and the other end of which is connected to the crossbeam 1.

[0027] Specifically, manually pulling the fixing block 13 causes the sliding rod 12 connected to its right end to move synchronously, and the fixing plate 15 also moves accordingly, thereby compressing the spring 14. As the spring 14 is compressed, the distance between the two blocking frames 17 gradually increases, which in turn increases the spacing of the clamping teeth 20 installed on the bottom right side of the blocking frame 17. After adjusting the spacing of the clamping teeth 20, they are placed on both sides of the prefabricated building panel to initially limit the position of the building panel. During the subsequent hoisting process, these two clamping teeth 20 can effectively prevent the building panel from slipping off the side due to instability of the center of gravity. When a hoisting operation is completed and the next hoisting operation is ready, the crane lowers the lifting ring 6. When the lifting ring 6 descends to a certain position, the spring 3 installed on the outer wall of the guide rod 2... The spring 3 begins to function, pushing the two sliders 4 in opposite directions. The movement of the sliders 4, in turn, drives the sliding frame 8 to move via the connecting rod 11, thereby releasing the clamping teeth 9 and preparing for the next hoisting operation. The guide rod 19 is slidably connected to the inner wall of the front fixing block 13 and is fixedly connected to the inner wall of the blocking frame 17, providing guidance for the movement of the blocking frame 17 and ensuring its stability and accuracy during movement. This ensures that the clamping teeth 20 can accurately limit the prefabricated building panels. The sliding rod 10 is installed on the inner wall of the two clamping teeth 9 on the left side, serving to guide and stabilize the clamping teeth 9, keeping them stable during movement and clamping of the prefabricated building panels, preventing them from shaking or shifting, and improving the accuracy and stability of clamping.

[0028] Working principle: The equipment is connected to the hook on the crane via the lifting ring 6. Then, according to the size of the object to be lifted, the fixing block 13 is pulled, compressing the spring 14 via the fixing plate 15, increasing the distance between the two blocking frames 17. Next, the two clamping teeth 20 limit the prefabricated building and prevent it from slipping off the side due to instability during lifting. Then, the clamping teeth 9 are moved to the bottom of the prefabricated building. Finally, the crane pulls the lifting ring 6 upwards. During the ascent, the lifting ring 6 will... The movable slider 4 moves, and when the slider 4 moves, it will drive the sliding frame 8 to move on the support beam 7 through the connecting rod 11, so that the clamping teeth 9 can clamp the prefabricated buildings of different sizes. During the pulling process, the construction personnel need to continuously press the support beam 7 until the clamping teeth 9 clamp the prefabricated building and then release. When the next hoisting is carried out, the crane lowers the lifting ring 6. After it is placed in a certain position, the two sliders 4 will move in the opposite direction under the action of the spring 3, which will drive the clamping teeth 9 to move through the connecting rod 11.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
