Description

Technical Field

[0001] This invention belongs to the field of prefabricated building technology, and in particular relates to a prefabricated building wall alignment and installation device and method. 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] In recent years, prefabricated buildings have been widely used in the construction of factory buildings, residential buildings and other buildings. The rapid development of prefabricated buildings has brought higher requirements to the installation of walls. When installing prefabricated building walls, it is necessary to observe whether the wall is installed in the correct position. When installing manually, workers need to lift the wall to find the correct position. The process is not only very troublesome, but also causes workers to become fatigued over time, which may cause the wall to slip out of their hands and pose a great safety hazard.

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] (1) The present invention designs a prefabricated building wall alignment installation device. Through overall structural optimization and coordination, it facilitates the auxiliary alignment and assembly of the wall during installation, without requiring workers to visually observe whether the installation position is aligned, and without requiring workers to lift the wall throughout the process, which effectively improves the wall installation efficiency and can effectively ensure the alignment effect during wall installation.

[0024] (2) In this invention, the clamping mechanism is slidably mounted on the length of the cylinder via a sliding mechanism, which facilitates the movement of the second wall along the length of the connecting cylinder towards the first wall. Simultaneously, the sliding mechanism can also rotate the second wall around the connecting cylinder to meet the needs of different installation positions. The overall installation and alignment operation is simple. Furthermore, this invention further optimizes the specific structure of the sliding mechanism. Through the structural cooperation of the outer and inner sliding blocks, supplemented by the rotational limiting effect of the limiting mechanism, the stability of the sliding mechanism when driving the reinforcing mechanism and the second wall is improved, preventing deflection during sliding and affecting the alignment effect during wall installation.

[0037] As described in the background art, when installing prefabricated building walls, it is necessary to observe whether the wall is installed in the correct position. When installing manually, workers need to lift the wall to find the correct position. This process is not only very troublesome, but also causes workers to become fatigued over time, which can lead to the wall slipping out of their hands and poses a great safety hazard.

[0038] Based on the above, the present invention provides an alignment and installation auxiliary device and method for prefabricated building walls. Through the overall structural design, after the position of the first wall is limited and fixed, it is convenient to assist in the handling of the second wall when installing it with the first wall. It is also convenient to align and install the second wall to the upper part of the first wall or to any one of the two sides of the first wall. Therefore, it is not necessary for workers to visually observe whether the installation position is aligned, and workers do not need to lift the wall throughout the process, which reduces the workload of workers, makes it less likely to cause fatigue, and effectively reduces safety hazards.

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the embodiments of the present invention can be combined with each other.

[0040] Example 1

[0041] like Figure 1 , Figure 2 As shown, the prefabricated building wall alignment and installation device of this embodiment includes a mounting base 1, which is an L-shaped structure composed of a bottom horizontal beam and a longitudinal beam. A connecting cylinder 3 is horizontally supported on the top of the longitudinal beam of the mounting base 1. The connecting cylinder 3 is located directly above the bottom horizontal beam and the two are parallel. A sliding seat mechanism is slidably mounted along the length of the connecting cylinder 3. A clamping mechanism is provided at the end of the mounting base 1 away from the longitudinal beam for limiting and fixing the first wall 43. A clamping mechanism and a limiting mechanism are provided on the outside of the sliding seat assembly. The limiting mechanism is used to limit the rotation of the sliding seat assembly, and the clamping mechanism is used to clamp and fix the second wall 44. The sliding direction of the sliding seat mechanism is perpendicular to the installation direction of the first wall 43. The first wall 43 is fixed to one side of the mounting base 1 by a clamping mechanism, and the second wall 44 is clamped and fixed to the clamping mechanism. According to the installation position of the second wall 44 relative to the first wall 43, the clamping mechanism is rotated to a suitable angle by a sliding assembly and then limited by a limiting mechanism. Then, the second wall is moved along the connecting cylinder 3 towards the first wall by the sliding mechanism, which facilitates the alignment and installation of the second wall and the first wall without the need for manual alignment judgment. This solves the problems of low installation efficiency and difficulty in guaranteeing alignment effect that exist in the prior art where alignment is completely dependent on manual alignment.

[0042] As a further preferred embodiment, combined with Figure 3 The clamping mechanism in this embodiment includes a support base 7, which is fixedly installed on the end of the bottom crossbeam of the mounting base 1 away from the longitudinal beam. A vertical frame 9 is fixedly connected to the end of the bottom crossbeam near the support base 7 and the connecting cylinder 3. Thus, the mounting base 1, the connecting cylinder 3, and the vertical frame 9 are interconnected to form the basic frame of the entire device, thereby improving the structural stability of the entire device. The vertical frame 9 contains a clamping assembly used to clamp and position the first wall panel 43 onto the support base 7. Specifically, the clamping assembly includes a pressure plate 12 that is opposite to and cooperates with the support base 7. The vertical frame 9 contains a drive unit for driving the pressure plate 12 to slide up and down, and a first guide post 11 for guiding the pressure plate 12 to slide. The drive unit uses a hydraulic cylinder 10, which is fixedly installed inside the vertical frame 9. The telescopic end of the hydraulic cylinder 10 is fixed to the pressure plate 12. However, it should be noted that the drive unit is not limited to a hydraulic cylinder and can also use other drive sources. To further improve the fixation effect on the first wall, in this embodiment, mounting plates 8 are provided on both sides of the bottom crossbeam of the mounting base 1 and the upright 9, and the mounting plates 8 are reinforced with reinforcing ribs. The support base 7, mounting plates 8 and pressure plate 12 facilitate the positioning and fixation of the first wall 43.

[0043] As a further preferred embodiment, combined with Figure 5 As shown, the sliding mechanism of this embodiment includes an outer sliding block 22 and an inner sliding block 21 fitted inside and fixedly connected to the outer sliding block 22. The outer sliding block 22 is slidably fitted onto the outside of the connecting cylinder 3, and the inner sliding block 21 is slidably installed in the inner hole of the connecting cylinder 3. Furthermore, the inner hole sidewall of the connecting cylinder 3 is provided with a guide plate 4 for guiding the inner sliding block 21. The inner sliding block 21 is correspondingly machined with a guide groove that cooperates with the guide plate 4. The cooperation between the guide plate 4 and the guide groove can improve the sliding stability of the outer sliding block 22 and the inner sliding block 21 and prevent the outer sliding block 22 and the inner sliding block 21 from rotating. In this embodiment, the outer sliding block 22 and the inner sliding block 21 are fixedly connected by at least two connecting blocks distributed circumferentially. In order to ensure that the outer sliding block 22 and the inner sliding block 21 can slide together, the sidewall of the connecting cylinder 3 is correspondingly machined with a sliding groove that cooperates with the connecting blocks. In this embodiment, a driving component is provided at one end of the connecting cylinder 3 to drive the inner slide block 21 to slide along the inside of the connecting cylinder 3, thereby driving the outer slide block 22 to slide together.

[0044] Specifically, a hollow circular seat 2 is fixed to the top of the longitudinal beam supporting the base frame 1. One end of the connecting cylinder 3 is fixedly connected to the hollow circular seat 2. A first motor 5 is installed inside the hollow circular seat 2. A stud 6 is fixed to the output end of the first motor 5. The end of the stud 6 away from the first motor 5 passes through the inner slide 21 and is threadedly connected to the inner slide 21. The first motor 5 drives the stud 6 to rotate, thereby causing the inner slide 21 to move along the length of the connecting cylinder 3. In this embodiment, there are four guide plates 4, which are evenly distributed along the circumferential direction of the inner wall of the connecting cylinder 3. However, the number is not limited to four; for example, three or more can be provided.

[0045] In order to facilitate the installation of the second wall at different positions of the first wall (such as above or to the sides), in this embodiment, a support ring 23 is rotatably installed on the outer slide 22, and the clamping mechanism is fixedly installed on the support ring 23. Thus, the clamping mechanism can be rotated together by the support ring 23 to meet the needs of different installation positions of the second wall.

[0046] As a further preferred embodiment, combined with Figure 5 , Figure 6The limiting mechanism includes a mounting rail 25 and a lifting frame 27. The mounting rail 25 is slidably mounted on the bottom crossbeam of the mounting base 1 and located below the outer slide block 22, with its sliding direction parallel to the sliding direction of the slide block assembly. The lifting frame 27 is slidably mounted inside the mounting rail 25 and has a limiting block 29 on its top. The support ring 23 has a corresponding limiting groove 24 that matches the limiting block 29. The rotation of the support ring 23 can be limited by the cooperation between the limiting block 29 and the limiting groove 24. Furthermore, the mounting rail 25 has two second guide posts 26 symmetrically distributed on the left and right sides. The lifting frame 27 is slidably mounted on the second guide posts 26 and has a rack 28 inside. A rack drive assembly is mounted on the mounting rail 25. By cooperating with the rack 28, the rack 28 can be driven to move the lifting frame 27 up and down, thereby realizing the insertion or withdrawal of the limiting block 29 from the limiting groove 24. Specifically, the rack and pinion drive assembly in this embodiment includes a second motor 30, which is fixedly mounted on the inner wall of one side of the mounting base 25. Its output shaft is fixedly connected to one end of a connecting shaft 31, and the other end of the connecting shaft 31 is rotatably mounted on the inner wall of the other side of the mounting base 25. A spur gear 32 is mounted on the connecting shaft 31, and the spur gear 32 meshes with the rack 28. Furthermore, in this embodiment, there are three limiting grooves 24, and the three limiting grooves 24 and the clamping mechanism are evenly distributed circumferentially on the side of the support ring 23.

[0047] The working process of the limiting component is as follows: the second motor 30 is started to drive the connecting shaft 31 and the flat gear 32 to rotate. Through the meshing of the flat gear 32 and the rack 28, the lifting frame 27 is driven to move up and down by the guidance of the second guide post 26. This causes the limiting block 29 to move closer to or away from the limiting groove 24. When the limiting block 29 slides into the inner side of the limiting groove 24, it limits the support ring 23. After sliding out, the limiting is released. When the limiting block 29 slides into the inner side of the limiting groove 24, the limiting mechanism and the sliding mechanism form an integral whole. When the sliding mechanism moves, it is convenient to drive the limiting mechanism to move by the guidance of the mounting base 1. The structural design of the three limiting grooves 24 makes it easy to drive the clamping mechanism and the second wall 44 to flip to the upper end of the first wall 43 or to either side of the first wall 43 by the rotation of the support ring 23.

[0048] As a further preferred embodiment, such as Figure 7As shown, the clamping mechanism includes an extension plate 33, one end of which is fixedly mounted on the support ring 23, and the other end is fixed with a clamping assembly. Specifically, in this embodiment, the other end of the extension plate 33 is fixed with a C-shaped outer seat 34. The clamping assembly includes a clamping frame 35 and a clamping plate driving unit. The clamping frame 35 is fixedly mounted inside the C-shaped outer seat 34, and two opposing clamping plates 39 are slidably mounted inside the clamping frame 35. The clamping plate driving unit is used to drive the two clamping plates 39 to move relative to each other to clamp and fix the second wall panel 44.

[0049] Furthermore, the clamping plate driving unit includes a bidirectional screw 38, with both ends of the bidirectional screw 38 rotatably mounted on both ends of the clamping frame 35. Two clamping plates 39 are respectively threadedly connected to the corresponding sides of the bidirectional screw 38, and a third guide post 37 that slides between the two ends of the clamping frame 35 is connected to the clamping plates 39. A third motor 41 is fixedly mounted on the clamping frame 35, and a second bevel gear 42 is fixedly mounted on the output end of the third motor 41. A first bevel gear 40 is fixedly mounted on the outer side of the bidirectional screw 38, and the second bevel gear 42 meshes with the first bevel gear 40. The third motor 41 drives the second bevel gear 42 to rotate, thereby driving the bidirectional screw 38 to rotate through the first bevel gear 40, thus causing the two clamping plates 39 to slide relative to each other, achieving the clamping and loosening of the second wall. Furthermore, in this embodiment, the third motor 41, the first bevel gear 40, and the second bevel gear 42 are all installed inside the inner fixed seat 36. The inner fixed seat 36 is located at the center of the clamping frame 35. The inner fixed seat 36 can be used to install the third motor 41, the first bevel gear 40, and the second bevel gear 42, and it also helps to limit the second wall and improve the stability of its clamping and fixing.

[0050] As a further preferred embodiment, to facilitate the movement of the device, a movable pulley 13 is installed on one side wall of the longitudinal beam supporting the base frame 1. When the device needs to be used, it needs to be flipped over. To facilitate flipping, an L-shaped support plate 14 is provided at the bottom corner of the longitudinal beam. Furthermore, after the device is flipped over, to facilitate auxiliary support on both sides of the device, auxiliary support mechanisms are provided on the two opposite side walls of the longitudinal beam that are perpendicular to the side wall where the movable pulley 13 is installed.

[0051] Specifically, such as Figure 4As shown, the auxiliary support mechanism in this embodiment includes a fixed base 15, a rotating shaft 16, and an auxiliary support 18. The fixed base 15 is fixedly installed on the side wall of the longitudinal beam of the mounting base 1. Both ends of the rotating shaft 16 are rotatably installed on the fixed base 15. The auxiliary support 18 is fixedly connected to the rotating shaft 16 through a connecting plate 17. One end of the rotating shaft 16 is slidably connected to a pull rod 19 that passes through the fixed base 15 and the rotating shaft 16. A limit cap is provided at the top of the pull rod 19, and a spring 20 is fitted on the outside of the pull rod 19 between the limit cap and the fixed base 15. The pull rod 19 facilitates limiting the rotating shaft 16 before and after it is flipped.

[0052] As a further preferred embodiment, when the first wall 43 or the second wall 44 is squeezed and fixed, in order to increase the friction between the first wall 43 or the second wall 44 and thus improve the fixing effect, the outer sides of the mounting plate 8, the pressure plate 12 and the clamping plate 39 are all fixed with an anti-slip layer.

[0053] Using the device of this embodiment, the first wall 43 is installed on the clamping mechanism and fixed in a limited position; the second wall 44 is placed on the clamping mechanism and clamped in a fixed position. Based on the installation position of the second wall 44 relative to the first wall 43, the clamping mechanism and the second wall 44 are rotated to the required angle by the sliding assembly and limited by the limiting mechanism. Then, the sliding assembly moves the clamping mechanism and the second wall 44 along the connecting cylinder 3 to a suitable position, thereby assisting in the alignment and installation of the second wall 44 and the first wall 43. The specific usage process of this device is as follows;

[0054] First, move the device to the installation location using the movable pulley 13. When the device is needed, flip it over using the L-shaped support plate 14 as a fulcrum. The flipped device is as follows: Figure 1 As shown, after flipping, pulling the lever 19 releases the limit on the rotating shaft 16, causing the rotating shaft 16 to flip, which in turn causes the connecting plate 17 and the auxiliary support 18 to flip, thereby making the auxiliary support 18 contact the ground, which facilitates the auxiliary support of the device. After the rotating shaft 16 flips, the lever 19 is released, and the elasticity of the spring 20 facilitates the lever 19 to reset, thereby re-limiting and fixing the rotating shaft 16.

[0055] When the second wall 44 needs to be aligned and installed on the outside of the first wall 43, the position of the first wall 43 needs to be fixed first. After the first wall 43 is lifted to the upper end of the support seat 7 and attached to the plate 8, the hydraulic cylinder 10 is started to drive the pressure plate 12 to move down through the guide of the first guide post 11 to squeeze and fix the top of the first wall 43, thus completing the limiting and fixing of the first wall 43.

[0056] Next, the second wall 44 is lifted into the clamping assembly and clamped and fixed by the clamping assembly, thus facilitating the transport of the second wall 44 to the outside of the first wall 43 for alignment and installation. Specifically, when the second wall 44 needs to be installed on the upper part of the first wall 43, the second wall 44 is placed horizontally between the two clamping plates 39, with the end of the second wall 44 near the slide assembly flush with and fitted against the inner fixed seat 36. When the second wall 44 needs to be installed on either side of the first wall 43, the second wall 44 is placed vertically between the two clamping plates 39.

[0057] After the second wall 44 is placed, the third motor 41 is started to drive the second bevel gear 42 to rotate. The meshing of the second bevel gear 42 with the first bevel gear 40 drives the bidirectional screw 38 to rotate, which in turn drives the two clamping plates 39 to move closer together under the guidance of the third guide post 37, thus squeezing and fixing the second wall 44. When the second wall 44 needs to be installed on top of the first wall 43, the rotation limit of the support ring 23 needs to be released. Rotating the support ring 23 then causes the clamping mechanism to flip, thereby causing the second wall 44 to flip to the top of the first wall 43. After flipping, the support ring 23 is again limited and fixed by the limit mechanism. Then, the first motor 5 is started to drive the screw 6 to rotate, further moving the sliding mechanism, the limit mechanism, and the clamping mechanism closer to the first wall 43, so that the second wall 44 finally moves to the top of the first wall 43 (in conjunction with...). Figure 8 (As shown), then manually remove the second wall 44 from the clamping mechanism so that the second wall 44 is attached to the upper end of the first wall 43 for easy alignment and installation later.

[0058] When the second wall 44 needs to be installed on either side of the first wall 43, after releasing the limiting mechanism from the support ring 23, the support ring 23 is rotated to cause the clamping mechanism and the second wall 44 to flip, so that the second wall 44 flips to either side of the first wall 43. After flipping, the limiting mechanism is used to limit and fix the support ring 23, which in turn moves the sliding mechanism, the limiting mechanism, and the clamping mechanism closer to the first wall 43, aligning one side of the second wall 44 with one side of the first wall 43. Then, the second wall 44 is removed from the clamping mechanism, and the second wall 44 is manually pushed to move closer to the first wall 43, so that the second wall 44 fits against the side of the first wall 43, thus facilitating subsequent alignment and installation (in conjunction with...). Figure 9 (As shown).

[0059] After the second wall 44 and the first wall 43 are aligned and installed to form an integral wall, the clamping mechanism and the pressure mechanism are released from limiting and fixing the second wall 44 and the first wall 43, thereby facilitating the removal of the second wall 44 and the first wall 43 as a whole from this device.
