Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated building construction, and particularly to an installation positioning device for a stable composite slab of a prefabricated structure. Background Art

[0002] A prefabricated building refers to a building assembled on-site by transporting prefabricated building components and fittings processed and manufactured in a factory to the construction site through reliable connection methods. The main functions of prefabricated buildings include:

[0003] Shortening the construction period: Traditional building construction is greatly affected by factors such as weather and environment, making it difficult to ensure the construction progress. However, the components of prefabricated buildings are prefabricated in the factory, with less interference from the external environment and high production efficiency. At the same time, on-site construction mainly involves assembly operations, with a fast construction speed, which can significantly shorten the overall construction period. Assembly line production: The factory adopts a standardized and assembly line production method, which can efficiently mass-produce building components, improving production efficiency and the consistency of product quality. Precision manufacturing: The factory production environment is stable, and advanced production equipment and processes can be used to precisely control the dimensions, shapes, strengths, etc. of building components, ensuring that the quality of the components meets the standards. In contrast, there are more manual operations at the traditional building construction site, resulting in greater quality fluctuations. Quality traceability: There is a strict quality inspection and recording system during the production process of prefabricated building components, and each component has a unique identifier, enabling quality traceability. Reducing construction waste: A large amount of construction waste is generated at the traditional building construction site. Reducing energy consumption: Centralized energy supply, waste heat recovery and other energy-saving technologies can be adopted in factory production to improve energy utilization efficiency.

[0004] However, in actual use of the existing technology, during the construction of prefabricated buildings, as a common precast component, composite slabs are widely used in floor slabs, roof slabs and other parts. However, during the installation and construction of composite slabs, there are many problems with traditional installation methods; for example, the installation of composite slabs mainly relies on manual or simple mechanical equipment for handling, which not only has a high labor intensity and low efficiency, but also it is difficult to ensure the stability of the composite slab during the installation and movement process, easily causing damage to the composite slab, thus affecting the installation and positioning of the composite slab. Summary of the Invention

[0005] The object of the present invention is to provide an installation positioning device for a stable laminated slab of an assembled structure, so as to solve the problems raised in the above-mentioned background technology. During the construction of assembled buildings, the laminated slab, as a common precast component, is widely used in floors, roof slabs and other parts.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Meanwhile, when the laser emitter is turned on in the present invention, it emits laser towards directly below the positioning frame, enabling laser positioning indication for directly below the positioning frame through the laser. When the moving body moves to the installation position required for the laminated board, the first electric telescopic rod is controlled to extend downward. When the first electric telescopic rod extends downward, it drives the connecting cross bar to linearly move downward. When the connecting cross bar linearly moves downward, it drives the connecting rod to move downward. When the connecting rod moves downward, it drives the push rod to swing outward. When the push rod swings outward, it drives the swing shaft rod to rotate. When the swing shaft rod rotates, it drives the horizontal support plate to swing outward and open, thus releasing the support and limit for the bottom of the laminated board;

[0019] Meanwhile, when the positioning frame linearly moves downward in the present invention, it drives the clamped and positioned laminated board to linearly move downward and lower. When the laminated board linearly moves downward and lowers, the first electric telescopic rod is controlled to contract. When the first electric telescopic rod contracts, it synchronously drives the clamping plate to contract. When the clamping plate contracts, it releases the clamping and positioning of the laminated board. When the clamping and positioning of the laminated board is released, the laminated board will fall to the required installation position under the action of its own gravity, thus realizing the positioning and movement of the laminated board and facilitating the installation and lowering of the laminated board after positioning and movement.

[0031] An installation groove 210 is provided at the lower side of the front end of the positioning frame 2. A first electric telescopic rod 211 is fixedly installed at the top end inside the installation groove 210. The telescopic part at the lower end of the first electric telescopic rod 211 is fixedly installed with a connecting cross bar 212. Limit sliding rails 213 are fixedly installed on both sides of the front end of the positioning frame 2. And the connecting cross bar 212 is limited and fitted to be movably connected to the outer side of the upper end of the limit sliding rail 213, so that the vertical linear movement of the connecting cross bar 212 is limited by the limit sliding rail 213. Connecting rods 214 are rotatably connected to both sides of the connecting cross bar 212 through pin shafts. And the number of the connecting rods 214 is two, which are symmetrically distributed on both sides of the connecting cross bar 212. The lower ends of the connecting rods 214 are inclined outward. Swing shaft rods 215 are rotatably connected to both sides of the lower end of the positioning frame 2 through rotating shafts. And the number of the swing shaft rods 215 is two, which are symmetrically distributed on both sides of the lower end of the positioning frame 2.

A push rod 217 is fixedly installed at the rear end of the swing shaft rod 215. And the inner side of the push rod 217 faces the middle part of the lower end of the positioning frame 2.

And the clamping plate 221 is hidden inside the shrinkage groove 219. An anti-slip pad is bonded to the side end of the clamping plate 221.

And the outer sides of the second limit sliding rods 222 penetrate and are fitted to be movably connected to the outer side of the lower end of the positioning frame 2, so that the horizontal linear movement of the clamping plate 221 is limited by the second limit sliding rods 222.

[0033] During use, the laminated board to be installed is loaded and unloaded into the positioning frame 2. When the laminated board is loaded and unloaded into the positioning frame 2, the horizontal support plate 216 supports and limits the bottom of the laminated board. When the horizontal support plate 216 supports and limits the bottom of the laminated board, the controller synchronously controls the second electric telescopic rod 220 to extend. When the second electric telescopic rod 220 extends, it drives the clamping plate 221 to linearly move towards the inner side of the lower end of the positioning frame 2. When the clamping plate 221 linearly moves towards the inner side of the lower end of the positioning frame 2, it clamps and positions the outer side of the laminated board inside the positioning frame 2. When the laminated board is clamped and positioned, the driving motor 103 is controlled to be turned on. When the driving motor 103 is turned on, it drives the crawler wheel 106 to rotate. When the crawler wheel 106 rotates, it drives the moving crawler 104 to rotate. When the moving crawler 104 rotates, it drives the moving body 1 to move. When the moving body 1 moves, it drives the clamped and positioned laminated board to move, thus realizing the function of facilitating the positioning and movement of the laminated board;

[0034] When the laminated board is positioned and moved, the laser emitter 218 is controlled to be turned on. When the laser emitter 218 is turned on, it emits laser towards directly below the positioning frame 2, so that the area directly below the positioning frame 2 is indicated by laser for positioning. When the moving body 1 moves to the installation position required for the laminated board, the first electric telescopic rod 211 is controlled to extend downward. When the first electric telescopic rod 211 extends downward, it drives the connecting cross bar 212 to linearly move downward. When the connecting cross bar 212 linearly moves downward, it drives the connecting rod 214 to move downward. When the connecting rod 214 moves downward, it drives the push rod 217 to swing outward. When the push rod 217 swings outward, it drives the swing shaft rod 215 to rotate. When the swing shaft rod 215 rotates, it drives the horizontal support plate 216 to swing outward and open. When the horizontal support plate 216 swings outward and opens, the support and limit on the bottom of the laminated board are released;

[0035] When the support limit for the bottom of the laminated slab is released, the control motor 203 is controlled to start. When the control motor 203 starts, it drives the first synchronous pulley 204 to rotate. When the first synchronous pulley 204 rotates, it drives the second synchronous pulley 205 to rotate through synchronous belt transmission. When the second synchronous pulley 205 rotates, it drives the transmission shaft rod 206 to rotate. When the transmission shaft rod 206 rotates, it drives the transmission worm 207 to rotate. When the transmission worm 207 rotates, it meshes with and drives the transmission worm wheel 209 to rotate. When the transmission worm wheel 209 rotates, it drives the internal thread transmission pipe 208 to rotate. When the internal thread transmission pipe 208 rotates, the support screw 223 is driven to move downward due to the force generated by the threaded connection. When the support screw 223 moves downward, it drives the positioning frame 2 to move linearly downward through the support enclosure 201. When the positioning frame 2 moves linearly downward, it drives the laminated slab held and positioned to move linearly downward and be lowered. When the laminated slab moves linearly downward and is lowered, the first electric telescopic rod 211 is controlled to contract. When the first electric telescopic rod 211 contracts, it synchronously drives the clamping plate 221 to contract. When the clamping plate 221 contracts, the clamping and positioning of the laminated slab are released. When the clamping and positioning of the laminated slab are released, the laminated slab will fall to the required installation position under the action of its own gravity, thereby realizing the positioning and movement of the laminated slab and facilitating the installation and lowering of the laminated slab after positioning and movement.
