Description

Technical Field

[0001] This invention relates to the field of prefabricated building construction equipment technology, and in particular to a rapid assembly and positioning device for prefabricated building walls. Background Technology

[0002] Prefabricated construction refers to a construction method in which some or all of the building components are manufactured in a prefabrication factory and then assembled on the construction site using reliable installation methods and machinery to create a functional building.

[0003] Currently, most prefabricated building wall splicing methods involve hoisting combined with manual adjustment and alignment with a pre-set positioning and splicing structure. Some methods use auxiliary alignment structures for corner or side-by-side wall splicing, but these still require hoisting support. While CN116446662A discloses a prefabricated building wall installation auxiliary device that includes functions for fixed transportation and upright splicing, it cannot perform fine-tuning during splicing, resulting in unevenness between the spliced ​​wall and the previous wall, affecting the quality of the prefabricated building. Therefore, this invention proposes a rapid splicing and positioning device for prefabricated building walls to solve the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a rapid assembly and positioning device for prefabricated building walls. This device, through a right-angle sleeve, support rollers, and a centering clamp driven by a synchronous electric rod in the positioning frame mechanism, can accurately center and position a fixed wall. Simultaneously, the wall movement and positioning mechanism can achieve multi-degree-of-freedom posture adjustment and horizontal fine-tuning during the movement and pushing of the wall to be assembled, ensuring that the wall to be assembled is accurately aligned and smoothly connected with the fixed wall.

[0005] To achieve the objectives of this invention, the following technical solution is provided: A rapid assembly and positioning device for prefabricated building walls, comprising a positioning frame mechanism and a wall movement and positioning mechanism. The positioning frame mechanism includes a right-angle sleeve, support rollers, a positioning clamping mechanism, and inclined positioning guide plates. Support rollers are symmetrically arranged at the top of the right-angle sleeve, and positioning clamping mechanisms are symmetrically arranged within the right-angle sleeve. Inclined positioning guide plates are symmetrically arranged on the sides of both sides of the right-angle sleeve. The wall movement and positioning mechanism includes a moving frame, a pushing electric rod, a pushing frame, a lifting mechanism, a lifting frame, a horizontal fine-tuning mechanism, and a clamping support mechanism. A pushing frame is provided in the moving frame via the pushing electric rod for pushing and assembling the prefabricated wall that is clamped and supported. A lifting frame is provided in the pushing frame via the lifting mechanism. Horizontal fine-tuning mechanisms are symmetrically arranged on both sides of the moving frame to facilitate fine-tuning of the height and verticality of the transported wall during assembly, ensuring that the wall remains vertical. A clamping support mechanism is provided inside the lifting frame and on the lower side of the moving frame.

[0006] Further improvements include: a main controller is provided above the lifting frame, and a control panel is provided on one side of the moving frame. The control panel, positioning clamp mechanism, push electric rod, lifting mechanism, horizontal fine adjustment mechanism, and clamping support mechanism are all electrically connected to the main controller. The main controller and the positioning clamp mechanism communicate wirelessly. An independent power supply is provided on the right-angle sleeve for power supply control of the positioning clamp mechanism. A push handle is also provided on one side of the moving frame.

[0007] A further improvement is that the positioning clamping mechanism includes a centering synchronous electric rod, a centering clamping plate, and a guide slide rod. The centering clamping plate is symmetrically provided on the inner side of the right-angle sleeve through the centering synchronous electric rod. The telescopic ends of the centering synchronous electric rod are arranged opposite each other, and the centering clamping plate is fixed at its telescopic end. The guide slide rod is also symmetrically provided between the outer side of the centering clamping plate and the side wall of the right-angle sleeve.

[0008] A further improvement is made in that: the lifting mechanism includes a synchronous screw, a lifting guide rod, a lifting motor, and a synchronous toothed belt.

The synchronous screw is threaded into the side walls of the pushing frame. The lifting guide rod is slidably inserted into the side walls of the pushing frame. The lifting motor is fixedly arranged on the top of the lifting frame. The output end of the lifting motor is connected to the upper end of the synchronous screw through a synchronous toothed belt for transmission.

[0009] Further improvements include: the horizontal fine-tuning mechanism includes a tilt sensor, a support electric rod, a universal joint, and a movable support plate. The tilt sensor is located at the top center of the inner side of the lifting frame. Specifically, a protective cover is provided at the top of the lifting frame outside the tilt sensor to prevent collision damage to the tilt sensor. Support electric rods are symmetrically arranged on both sides of the moving frame, and four sets of support electric rods are symmetrically arranged. The movable support plate is located at the universal joint with the telescopic end of the support electric rod facing downward.

[0010] A further improvement is made in that: the clamping support mechanism includes a clamping cylinder, an anti-slip clamping plate, a clamping plate guide rod, a movable groove, a support insert plate, and a closing electric rod. The lifting frame is symmetrically provided with anti-slip clamping plates through the clamping cylinder. The outer side of the anti-slip clamping plate is also symmetrically provided with clamping plate guide rods between the outer side of the anti-slip clamping plate and the side wall of the lifting frame. The clamping plate guide rods are fixed to the outer side of the anti-slip clamping plate and slide through the side wall of the lifting frame. The lower ends of both sides of the movable frame are symmetrically provided with movable grooves. The support insert plate is movably provided in the movable grooves. The lower ends of both sides of the movable frame are symmetrically fixed with closing electric rods.

[0011] Further improvements include: the push frame has clearance grooves on both sides corresponding to the positions of the clamping cylinder and the clamping plate guide rod; one side of the support plate has a splicing plate at its end; and the other side of the support plate has a splicing slot at its end. The splicing plate and the splicing slot are matched accordingly to improve the support capacity of the support plate after splicing.

[0013] Further improvements include: symmetrical casters are provided on both sides of the lower part of the movable frame to facilitate the movement of the device. Self-locking casters can be reasonably selected. One end of the movable frame is guided and connected to the end of the right-angle sleeve through the inclined positioning guide plates on both sides of the right-angle sleeve, so as to achieve precise positioning and connection of the splicing wall.

[0014] A further improvement is that the right-angle sleeve is composed of two sleeve frames spliced ​​at right angles, and the two end faces and the bottom of the sleeve frames are open structures, which are used to fit onto the fixed prefabricated wall.

[0015] The beneficial effects of this invention are as follows: This invention, through the right-angle sleeve, support roller, and centering clamp driven by the centering synchronous electric rod in the positioning frame mechanism, can accurately center and position the fixed wall. At the same time, the pushing electric rod, lifting mechanism, clamping support mechanism, and horizontal fine-tuning mechanism with tilt sensor and support electric rod in the wall moving and positioning mechanism work together to achieve multi-degree-of-freedom posture adjustment and horizontal fine-tuning during the movement and pushing of the wall to be spliced, ensuring that the wall to be spliced ​​is accurately aligned and flatly connected with the fixed wall, thereby effectively eliminating unevenness after splicing and significantly improving the splicing quality and construction efficiency of prefabricated building walls.

These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0023] Example 1

[0024] according to Figures 1-5As shown, this embodiment provides a rapid splicing and positioning device for prefabricated building walls, including a positioning frame mechanism and a wall moving and positioning mechanism. The positioning frame mechanism includes a right-angle sleeve 1, a support roller 2, a positioning clamp mechanism, and an inclined positioning guide plate 3. The support roller 2 is symmetrically arranged at the top of the right-angle sleeve 1. Specifically, the support roller is symmetrically arranged at the top of the right-angle sleeve for convenient movement of the right-angle sleeve. The positioning clamp mechanism is symmetrically arranged in the right-angle sleeve 1. The inclined positioning guide plates 3 are symmetrically arranged on the sides of both sides of the right-angle sleeve 1 for positioning and centering of the wall moving and positioning mechanism, which facilitates precise positioning and splicing of the prefabricated wall.

[0025] The positioning clamping mechanism includes a centering synchronous electric rod 11, a centering clamping plate 12, and a guide slide rod 13. The centering clamping plate 12 is symmetrically arranged on the inner side of the right-angle sleeve 1 through the centering synchronous electric rod 11. The telescopic ends of the centering synchronous electric rod are arranged opposite each other, and the centering clamping plate is fixed to its telescopic end. The guide slide rod 13 is also symmetrically arranged between the outer side of the centering clamping plate 12 and the side wall of the right-angle sleeve 1. The guide slide rod is adapted to slide and guide the right-angle sleeve side wall.

[0026] The wall moving and positioning mechanism includes a moving frame 4, a pushing electric rod 5, a pushing frame 6, a lifting mechanism, a lifting frame 7, a horizontal fine-tuning mechanism, and a clamping support mechanism. The moving frame 4 is equipped with a pushing frame 6 through the pushing electric rod 5, which is used to push and splice the prefabricated wall that is clamped and supported. The pushing frame 6 is equipped with a lifting frame 7 through the lifting mechanism.

[0027] The lifting mechanism includes a synchronous screw 14, a lifting guide rod 15, a lifting motor 16, and a synchronous toothed belt 17. The synchronous screw 14 is symmetrically arranged on both sides of the lifting frame 7. Specifically, two sets of extension plates are symmetrically arranged on both sides of the lifting frame. The synchronous screw passes through the upper and lower sets of extension plates and is adapted to their rotation. The lifting guide rod 15 is symmetrically arranged on the sides of the lifting frame 7 on both sides of the synchronous screw 14. The lifting guide rod is fixedly arranged below the lower extension plate. The synchronous screw 14 is threaded into the side walls of the pushing frame 6 and the lifting guide rod 15 is slidably inserted into the side walls of the pushing frame 6. The lifting motor 16 is fixedly arranged on the top of the lifting frame 7. The output end of the lifting motor 16 is connected to the upper end of the synchronous screw 14 through the synchronous toothed belt 17. Specifically, the upper end of the synchronous screw on both sides is provided with a synchronous pulley, and the output end of the lifting motor is provided with a double-layer synchronous pulley. The synchronous toothed belt is connected to the synchronous screw on both sides in upper and lower layers respectively.

[0028] The movable frame 4 is symmetrically equipped with horizontal fine-tuning mechanisms on both sides to facilitate fine-tuning of the height and verticality of the walls during the splicing process, so that the walls always remain vertical.

[0029] The horizontal fine-tuning mechanism includes an inclination sensor 18, a support electric rod 19, a universal seat 20, and a movable support plate 21. An inclination sensor 18 is installed at the top center of the inner side of the lifting frame 7. Specifically, a protective cover is installed at the top of the lifting frame outside the inclination sensor to prevent the inclination sensor from being damaged by collision. Support electric rods 19 are symmetrically arranged on both sides of the moving frame 4. There are four sets of support electric rods symmetrically arranged. The telescopic end of the support electric rod 19 faces downward and is connected to the movable support plate 21 through the universal seat 20. Specifically, after the splicing wall is moved to the position to be spliced, the inclination sensor detects the overall verticality of the splicing wall after it is clamped, and the verticality of the splicing wall is adjusted by independently fine-tuning the support electric rod to keep it perpendicular to the fixed wall splicing.

[0030] A clamping and support mechanism is provided inside the lifting frame 7 and on the lower side of the movable frame 4 to clamp and support the wall to be spliced.

[0031] The clamping support mechanism includes a clamping cylinder 22, an anti-slip clamping plate 23, a clamping plate guide rod 24, a movable groove 25, a support insert plate 26, and a closing electric rod 27. Anti-slip clamping plates 23 are symmetrically arranged inside the lifting frame 7 via the clamping cylinder 22. Specifically, the telescopic ends of the clamping cylinders are arranged opposite each other, and the anti-slip clamping plates are fixed to the telescopic ends of the clamping cylinders. A clamping plate guide rod 24 is also symmetrically arranged between the outer side of the anti-slip clamping plate 23 and the side wall of the lifting frame 7. The clamping plate guide rod is fixed to the outer side of the anti-slip clamping plate and slides through the side wall of the lifting frame. Movable grooves 25 are symmetrically arranged at the lower ends of both sides of the moving frame 4. A support insert plate 26 is movably arranged in the movable groove 25. A closing electric rod 27 is symmetrically fixed at the lower ends of both sides of the moving frame 4. The telescopic ends of the closing electric rod 27 are fixedly connected to the support insert plate 26 with their outward-facing ends. Specifically, the support insert plate has an L-shaped structure, and the telescopic ends of the closing electric rod are fixedly connected to the side of the vertical plate of the support insert plate with their outward-facing ends.

[0032] The push frame 6 has clearance grooves 28 on both sides corresponding to the positions of the clamping cylinder 22 and the clamping guide rod 24. A splicing plate 29 is provided at the end of one side of the support plate 26, and a splicing slot 30 is provided at the end of the other side of the support plate 26. The splicing plate 29 and the splicing slot 30 are matched to each other to improve the support capacity after the support plates are spliced.

[0033] A main controller 8 is installed above the lifting frame 7, and a control panel 9 is installed on one side of the moving frame 4. The control panel 9, the positioning clamp mechanism, the push electric rod 5, the lifting mechanism, the horizontal fine adjustment mechanism, and the clamping support mechanism are all electrically connected to the main controller 8. Specifically, the main controller can have a built-in power supply for overall control. The main controller and the positioning clamp mechanism communicate wirelessly. An independent power supply is installed on the right-angle sleeve for power supply control of the positioning clamp mechanism. A push handle 10 is also installed on one side of the moving frame 4 for pushing the wall to move the positioning mechanism.

[0034] The inner walls of both sides of the movable frame 4 are symmetrically provided with guide grooves 31, and the front end of the guide groove is open. The two sides of the push frame 6 are symmetrically fixed with guide strips 32, which are slidably adapted to the guide grooves 31. The push electric rod 5 is fixed on one side of the movable frame 4 and its telescopic end is fixedly connected to the push frame 6 with the inside facing the outside. The push electric rod drives the push frame to move forward.

[0035] The movable frame 4 is symmetrically equipped with casters 33 on both sides of the lower part to facilitate the movement of the device. The casters can be self-locking casters. One end of the movable frame 4 is guided and connected to the end of the right angle frame 1 through the inclined positioning guide plates 3 on both sides of the right angle frame 1 to achieve precise positioning and connection of the splicing wall.

[0036] Specifically, the inclined positioning guide plate can also be equipped with an electric locking pin, driven by an electric cylinder. The corresponding position on the side of the moving frame is provided with a locking pin hole, which is locked after the moving frame is connected to one side of the right-angle sleeve to prevent the wall moving positioning mechanism from moving during splicing.

[0037] The right-angle sleeve 1 is composed of two sleeve frames spliced ​​at right angles, and both ends and the bottom of the sleeve frames are open structures. It is used to fit onto the fixed prefabricated wall to adapt to the side-by-side splicing or right-angle corner splicing of the spliced ​​walls.

[0038] Example 2

[0039] This embodiment provides a specific construction method for a rapid assembly and positioning device for prefabricated building walls, including:

[0040] 1. First, place the right-angle sleeve onto the end of the fixed splicing wall, making its end flush with the side of the right-angle sleeve. Then, use the positioning clamp mechanism to simultaneously clamp the splicing wall, completing the centering and fixing of the right-angle sleeve.

[0041] 2. Then, push the wall moving and positioning mechanism to the wall to be spliced, adjust the height of the lifting frame through the lifting mechanism so that it is slightly higher than the top of the wall to be spliced, then move the whole device to the outside of the wall, fit the wall, and then use the clamping cylinder to drive the anti-slip clamping plate to clamp the wall. At the same time, lift the wall through the lifting mechanism so that the bottom of the wall is higher than the support plate. Then, use the closing electric rod to drive the support plates on both sides to close and splice, thus supporting the wall.

[0042] 3. Next, move the wall moving positioning mechanism together with the lifted wall to one side of the right-angle frame. At this time, depending on the splicing requirements, choose whether to splice perpendicular to the fixed wall or side by side with the fixed wall. Move the wall moving positioning mechanism to the corresponding side. After connecting the moving frame with the side of the right-angle frame through the guide of the inclined positioning guide plate, the moving frame is slightly lifted by the four sets of movable support plates driven by the support electric rod to achieve fixed support.

[0043] 4. Then, the verticality of the wall to be spliced ​​is detected by the tilt sensor, and the wall is kept vertical by independent extension and retraction of the support electric rod. Since the spliced ​​wall is stably clamped by the mechanical structure in the moving frame, the verticality of the moving frame is the verticality of the wall to be spliced.

[0044] 5. After fine-tuning, the push frame is moved forward by pushing the electric rod, thereby moving the wall closer to the fixed wall. When it is close, the splicing support plate is opened, and the wall is lowered by the lifting mechanism so that the upper end of the wall to be spliced ​​is flush with the upper end of the fixed wall. The wall is then pushed to align the splicing structure and complete the splicing. After the splicing is completed, the wall movement positioning mechanism releases the wall and it exits.

[0045] If there is a gap at the bottom of the wall to be spliced ​​and the fixed wall after splicing, a wedge can be inserted into the bottom of the wall to fill and temporarily fix the position before the wall movement and positioning mechanism is released. After splicing, concrete can be filled in and solidified to support the wall.

[0046] 6. When the next step of splicing is required, simply repeat the above steps.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
