Description

Technical Field

[0001] This utility model relates to a concrete slab lifting tool, specifically a concrete autoclaved aerated concrete slab lifting tool, belonging to the field of lifting tool technology. Background Technology

[0002] Autoclaved aerated concrete (AAC) panels are a lightweight, porous, new type of green and environmentally friendly building material made primarily of cement, lime, and silica sand, with varying amounts of corrosion-resistant steel mesh added according to structural requirements.

[0003] When hoisting and transporting autoclaved aerated concrete panels, the panels are usually large and heavy. If the bearing surface of the hoisting equipment is too small, the panels may shake or even fall during transportation, which may also damage the panels at the bottom. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting tool for autoclaved aerated concrete panels in order to solve the above-mentioned problems. The lifting tool can be used for lifting and transporting panels of different sizes by means of telescopic mechanism. At the same time, the gear structure ensures that the telescopic length on both sides of the lifting tool is consistent, thereby ensuring that the center of gravity of the lifting tool remains unchanged during the lifting of panels and ensuring the stability of the lifting.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a concrete autoclaved aerated concrete panel lifting device, comprising a support frame, with telescopic structures connected to both ends of the support frame, each telescopic structure comprising a telescopic frame, and a telescopic frame slidably connected to each side of the support frame. The telescopic frames are in the shape of a "U". The two telescopic frames are slidably connected to each other. Two rotating shafts are rotatably connected to the inner side of the support frame. A first gear is fixedly connected to one end of each of the two rotating shafts, and the two first gears mesh with each other. A second gear is fixedly connected to the other end of the rotating shaft. The side of the telescopic frame has a toothed groove, and the second gear meshes with the telescopic frame through the toothed groove. A blocking structure is connected to the side of the telescopic frame.

[0006] Preferably, two pulleys are provided on both sides of the support frame, and the pulleys are rotatably connected to the support frame.

[0007] Preferably, the inner side of the support frame is provided with a brake tooth block, the side of the brake tooth block that is close to the first gear has a tooth-like structure, and the brake tooth block is slidably connected to the support frame.

[0008] Preferably, a trigger plate is slidably connected to the middle of the support frame, the brake tooth block is slidably connected to the trigger plate, and a first spring is fixedly connected to both ends of the brake tooth block and the trigger plate respectively.

[0009] Preferably, a second spring is fixedly connected to each side of the trigger plate and the support frame, and the top side of the trigger plate has a square structure.

[0010] Preferably, the blocking structure includes a limiting rod, which is rotatably connected to the side of the telescopic frame, and the limiting rod has a "U" shaped structure.

[0011] Preferably, the top side of the limiting rod is fixedly connected to two hanging rings, which are in the form of a "U" shape.

[0012] Preferably, the telescopic frame has a positioning groove on its inner side, and the limiting rod is slidably connected to a traction rod on its inner side. The end of the traction rod and the positioning groove are both cylindrical structures.

[0013] Preferably, the end of the traction rod engages with the telescopic frame via a positioning groove, and a third spring is fixedly connected between the traction rod and the limiting rod.

[0014] The beneficial effects of this utility model are as follows: The support frame is used to support the board material. When the board material has a large area, the user can pull out the telescopic frames on both sides of the support frame, thereby improving the load-bearing effect for large-volume boards. At the same time, when the telescopic frames extend, the telescopic frames on both sides will drive the rotating shafts on both sides to rotate through the transmission effect of the toothed grooves on the sides and the second gear. The other end of the rotating shaft is provided with a first gear. The two first gears mesh with each other, so that the telescopic frames on both sides can only extend or retract synchronously. This ensures that when the telescopic frames are used to support the board material, the center of gravity of the entire lifting device will not change due to the movement of the telescopic frames, thus improving the stability during the conveying of the board material.

Detailed Implementation

[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] Please see Figure 1-6 As shown, a concrete autoclaved aerated concrete (AAC) panel lifting device includes a support frame 1. Telescopic structures 2 are connected to both ends of the support frame 1. Each telescopic structure 2 includes a telescopic frame 201. A telescopic frame 201 is slidably connected to each side of the support frame 1. The telescopic frames 201 have a "U" shape and are slidably connected to each other. Two rotating shafts 204 are rotatably connected to the inner side of the support frame 1. A first gear 205 is fixedly connected to one end of each of the two rotating shafts 204, and the two first gears 205 mesh with each other. A second gear 206 is fixedly connected to the other end of each rotating shaft 204. A toothed groove 207 is provided on the side of the telescopic frame 201, and the second gear 206 meshes with the telescopic frame 201 through the toothed groove 207. A blocking structure 3 is connected to the side of the telescopic frame 201.

[0024] As a technical optimization of this utility model, two pulleys 203 are provided on both sides of the support frame 1. The pulleys 203 are rotatably connected to the support frame 1. The pulleys 203 facilitate short-distance movement of the lifting device and the supported plate, making loading convenient. A brake block 208 is provided on the inner side of the support frame 1. The side of the brake block 208 that is close to the first gear 205 has a toothed structure. The brake block 208 is slidably connected to the support frame 1. A trigger plate 202 is slidably connected to the middle of the support frame 1. The brake block 208 is slidably connected to the trigger plate 202. A first spring 209 is fixedly connected to both ends of the brake block 208 and the trigger plate 202. The two sides of the trigger plate 202 are respectively... A second spring 210 is fixedly connected to the support frame 1. The top side of the trigger plate 202 has a square structure. After the extension length of the telescopic frame 201 is adjusted, concrete slabs can be loaded. When the slab is placed on the support frame 1, it will press the trigger plate 202 on it, causing the trigger plate 202 to move to the bottom. The brake block 208 sliding on the inner side of the trigger plate 202 will mesh with the first gear 205 on the top side, thereby preventing the first gear 205 from rotating, thus achieving the braking effect on the telescopic frames 201 on both sides. The brake block 208 can move a short distance in the left and right direction inside the trigger plate 202 to ensure that the brake block 208 can accurately mesh with the first gear 205 and ensure the braking effect.

[0025] As a technical optimization of this utility model, the blocking structure 3 includes a limiting rod 301. The limiting rod 301 is rotatably connected to the side of the telescopic frame 201. The limiting rod 301 has a "U"-shaped structure. Two hanging rings 303 are fixedly connected to the top side of the limiting rod 301. The hanging rings 303 have a "U"-shaped structure. A positioning groove 305 is provided on the inner side of the telescopic frame 201. A pulling rod 302 is slidably connected to the inner side of the limiting rod 301. The end of the pulling rod 302 and the positioning groove 305 are both cylindrical structures. The end of the pulling rod 302 is connected to the telescopic frame 201 through the positioning groove 305. A third spring 304 is fixedly connected between the pull rod 302 and the limiting rod 301. A rotatable limiting rod 301 is provided on the side of the telescopic frame 201. The limiting rod 301 is used to limit the transport of the concrete slabs it carries, thereby preventing the slabs from falling off. The limiting rod 301 is provided with a hanging ring 303 for adding a binding rope. The limiting rod 301 can be fixed by the interlocking action between the pull rod 302 on the side and the positioning groove 305, thereby maintaining the limiting effect. When loading the slabs, the limiting rod 301 can be rotated to a horizontal state, thereby facilitating the loading of the slabs.

[0026] In use, the bearing frame 1 is first used to support the sheet material. When the sheet material is large, the user can pull out the telescopic frames 201 on both sides of the bearing frame 1 to improve the load-bearing effect for large-volume sheets. The pulleys 203 facilitate short-distance movement of the lifting device and the supported sheet material for easy loading. When the telescopic frames 201 extend, the telescopic frames 201 on both sides drive the rotating shafts 204 on both sides to rotate through the transmission effect of the side teeth 207 and the second gear 206. The other end of the rotating shaft 204 is equipped with a first gear 205. The two first gears 205 mesh with each other, ensuring that the telescopic frames 201 on both sides can only extend or retract synchronously. This ensures that when using the telescopic frames 201 to support the sheet material, the overall center of gravity of the lifting device will not change due to the movement of the telescopic frames 201, improving the stability during the conveying of the sheet material. After adjusting the extension length of the telescopic frames 201, the concrete sheet material can be loaded. When the sheet material is placed on the bearing frame 1, it will be compressed... The trigger plate 202 is positioned on the top, causing it to move downwards. The brake block 208 sliding inside the trigger plate 202 engages with the first gear 205 on the top, preventing the first gear 205 from rotating. This achieves a braking effect on the telescopic frames 201 on both sides. The brake block 208 can move short distances left and right inside the trigger plate 202, ensuring accurate engagement with the first gear 205 and maintaining the braking effect. (The last sentence appears to be incomplete and possibly refers to a different topic.) A rotatable limiting rod 301 is provided on the side of 01. The limiting rod 301 is used to limit the transport of the concrete slabs it carries, thereby preventing the slabs from falling. The limiting rod 301 is provided with a hanging ring 303 for adding a binding rope. The limiting rod 301 can be fixed by the interlocking action between the pull rod 302 on the side and the positioning groove 305, thereby maintaining the limiting effect. When loading the slabs, the limiting rod 301 can be rotated to a horizontal state, thereby facilitating the loading of the slabs.
