Description

Technical Field

[0001] This invention relates to the field of building auxiliary assembly technology, specifically to an auxiliary positioning and installation device for prefabricated wall panels. Background Technology

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories and then assembled on the construction site. Currently, the wall panels of prefabricated buildings are pre-formed in factories, and no formwork or watering is required during on-site installation. This has advantages such as saving water resources, shortening the construction period, reducing on-site material and equipment consumption, and reducing dust and noise pollution.

[0003] When hoisting wall panels, the grouting holes pre-drilled inside the wall panels need to be aligned with the steel bars embedded in the floor or foundation beams and inserted one by one. The current practice mainly relies on multiple workers to manually support and pry the wall panels for repeated adjustments to complete the alignment work. This process is labor-intensive, time-consuming, and workers need to work under or near the hoisted object, which poses a significant safety risk, is inefficient, and has safety hazards. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an auxiliary positioning and installation device for prefabricated wall panels, which can effectively solve the problems of low hole-aligning efficiency and insufficient safety in the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides an auxiliary positioning and installation device for prefabricated wall panels, including a movable base with multiple sets of wheels at the bottom, and an automatic positioning component. The automatic positioning component includes two sets of lateral adjustment blocks that can move closer to or further away from each other. A longitudinal adjustment sleeve is slidably mounted on the lateral adjustment block, and an adjustment gear for driving the longitudinal adjustment sleeve to extend is rotatably mounted on the lateral adjustment block. The automatic positioning component also includes a rack movably mounted in the movable base for selectively driving the adjustment gear to rotate. The first centering assembly includes a tray, a second connecting rod, and a support column slidably disposed on a movable seat. The second connecting rod is rotatably connected to the movable seat and located between the support column and the tray. One end of the second connecting rod is rotatably connected to a first connecting rod, and the other end of the first connecting rod is rotatably connected to the bottom of the tray. The end of the second connecting rod away from the tray is provided with a lever for actuating the support column.

[0006] Furthermore, the automatic positioning component also includes a drive threaded rod, which is rotatably disposed in the movable seat and threadedly connected to the transverse adjusting block. A drive source is provided on one side of the drive threaded rod, and two sets of transverse adjusting blocks are symmetrically distributed on both sides of the drive threaded rod. The longitudinal adjusting sleeve is located on the side of the transverse adjusting block closer to the pre-embedded steel bar, and the adjusting gear is located on the opposite side of the longitudinal adjusting sleeve.

[0007] Furthermore, the adjusting gear has a spring-shaped guide groove on its rotating shaft, and the longitudinal adjusting sleeve has a drive rod extending into the spring-shaped guide groove.

[0008] Furthermore, the rack has two sets and can move vertically and horizontally within the movable seat. The ends of the two sets of racks that are close to each other are provided with bidirectional cylinders. The moving ends of the bidirectional cylinders are respectively driven and connected to the two sets of racks. The top of the rack is provided with an auxiliary magnetic block, and the movable seat is provided with an electromagnetic block accordingly.

[0009] Furthermore, a pressure sensor is provided at one end of the adjusting gear shaft near the pre-embedded reinforcing bar, and the pressure sensor is connected to the electromagnetic block through a controller.

[0010] Furthermore, both the first and second links are provided in two sets, and a torsion spring for resetting is provided between the second link and the moving seat.

[0011] Furthermore, a telescopic strip is slidably installed on the support column, and an arc-shaped plate is provided on the telescopic strip.

[0012] Furthermore, it also includes a second centering component, which includes a fixed guide plate and a movable guide plate slidably mounted on the fixed guide plate. The fixed guide plate is provided with a guide groove one, and the movable guide plate is provided with a guide groove two and a guide groove three. An adjusting column located in the guide groove two is slidably mounted on the movable guide plate, and the other side of the adjusting column passes through the guide groove one and extends toward the wall panel component. An elastic pressure plate is elastically mounted on the fixed guide plate, and the end of the elastic pressure plate away from the wall panel component extends into the guide groove three.

[0013] Furthermore, the second guide groove is inclined, and the end of the two sets of guide grooves that are close to each other is lower than the other side. The third guide groove is inclined, and the side of the third guide groove that is close to the fixed guide plate is higher than the other side.

[0014] Furthermore, each set of support columns is provided with two sets of second centering components, one set of second centering components is set on the support column, and the other set is set on the telescopic strip. Beneficial effects

[0015] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. By driving the threaded rod to rotate, two sets of lateral adjustment blocks are pulled closer to each other. The shaft of the adjustment gear abuts against the pre-embedded steel bar, realizing automatic adjustment of the lateral distance of the moving seat. In conjunction with the pressure sensor set on the shaft of the adjustment gear, the magnetic pole of the electromagnetic block is changed to change the meshing state of the rack and the adjustment gear. Then, the adjustment gear is driven to rotate by the bidirectional cylinder to push the longitudinal adjustment sleeve to extend towards the pre-embedded steel bar, adjusting the distance between the moving seat and the pre-embedded steel bar, realizing automatic adjustment of the longitudinal distance of the moving seat. This realizes automatic adjustment of the equipment, reduces the time and cycle of manual adjustment, facilitates the installation of wall panel components in different positions and directions, improves work efficiency, and eliminates the need for direct manual contact with wall components, making it safer. 2. After the wall panel component is hoisted onto the support plate, the support plate descends and pushes the two sets of second links to rotate through the two sets of first links. This brings the ends of the two sets of second links closer to the support columns, thereby pulling the two sets of support columns to slide along the length of the moving seat. This achieves lateral alignment between the wall panel component and the moving seat. As the second alignment component follows the support columns and presses against both sides of the wall panel component, the elastic pressure plate is compressed and guides the movable guide plate to rise. With the combined guidance of guide groove two and guide groove one, the two sets of pressing columns are guided to clamp the wall panel component, achieving longitudinal alignment of the wall panel component. This enables rapid alignment of the wall panel component with the pre-embedded steel bars, improving installation efficiency. Third, by using the telescopic strip to move on the support column, the distance between the two sets of second centering components on the same side is increased, thereby maintaining the vertical parallelism of the components and preventing the bending deformation of the pre-embedded steel bars when aligning the holes. During the insertion process, the horizontality and verticality of the wall panel are simultaneously calibrated to improve installation accuracy and overall structural stability.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to embodiments.

[0021] See attached document Figure 1-6The prefabricated wall panel auxiliary positioning and installation device includes a movable base 1, with multiple sets of traveling wheels 11 at the bottom of the movable base 1. The traveling wheels 11 are electrically controlled guide wheels, which restrict the movement of the traveling wheels 11 and limit the movement of the movable base 1 when the movable base 1 is pressed. It also includes an automatic positioning component 2, which includes two sets of lateral adjustment blocks 22 that can move closer to each other and further away from each other. The lateral adjustment blocks 22 are rectangular, and longitudinal adjustment sleeves 23 are slidably installed on the lateral adjustment blocks 22. Adjustment gears 24 for driving the longitudinal adjustment sleeves 23 to extend are rotatably installed on the lateral adjustment blocks 22. The automatic positioning component 2 also includes a drive threaded rod 21, which is rotatably disposed in the movable base 1 and threadedly connected to the lateral adjustment blocks 22. One side of the drive threaded rod 21 is provided with A drive source, preferably a motor, is provided. Two sets of lateral adjusting blocks 22 are symmetrically distributed on both sides of the drive threaded rod 21. The rotation of the drive threaded rod 21 drives the two sets of lateral adjusting blocks 22 to move closer or further apart along the length of the moving seat 1. When the two sets of lateral adjusting blocks 22 move closer together and press against the embedded steel bar, the moving seat 1 and the embedded steel bar are laterally aligned. The longitudinal adjusting sleeve 23 is located on the side of the lateral adjusting block 22 closest to the embedded steel bar, and the adjusting gear 24 is located on the opposite side of the longitudinal adjusting sleeve 23. The rotating shaft of the adjusting gear 24 is provided with a spring-shaped guide groove 241, and the longitudinal adjusting sleeve 23 is provided with a drive rod 231 extending into the spring-shaped guide groove 241. The longitudinal adjusting sleeve 23 is slidably connected to the lateral adjusting block 22 through a limiting strip. When the adjusting gear 24 rotates... At the same time, with the cooperation of the spring-shaped guide groove 241 and the drive rod 231, the longitudinal adjusting sleeve 23 is gradually moved out of the transverse adjusting block 22 until the longitudinal adjusting sleeve 23 contacts and abuts against the pre-embedded steel bar, realizing the automatic adjustment of the longitudinal distance between the moving seat 1 and the pre-embedded steel bar. In addition, the automatic positioning component 2 also includes a rack 25 movably installed in the moving seat 1 for selectively driving the adjustment gear 24 to rotate. The rack 25 has two sets and can move vertically and horizontally in the moving seat 1. The ends of the two sets of racks 25 that are close to each other are provided with a bidirectional cylinder 26. The moving end of the bidirectional cylinder 26 is drivenly connected to the two sets of racks 25 respectively. The bidirectional cylinder 26 is used to push or pull the two sets of racks 25. The moving end of the bidirectional cylinder 26 is provided with a mechanism that can interact with the racks 25. A vertical sliding connector is provided. This connector allows the rack 25 to still be driven by the bidirectional cylinder 26 after vertical displacement. An auxiliary magnetic block 251 is located on the top of the rack 25, and a corresponding electromagnetic block 252 is located on the moving base 1. The vertical position change of the rack 25 is achieved through the mutual attraction or repulsion between the auxiliary magnetic block 251 and the electromagnetic block 252. A pressure sensor is located at the end of the adjusting gear 24 shaft near the pre-embedded reinforcing bar. The pressure sensor and the electromagnetic block 252 are connected via a controller. When the pressure sensor reaches a preset value, the current flowing through the electromagnetic block 252 is controlled to change the magnetic poles of the electromagnetic block 252. Initially, the mutual attraction between the auxiliary magnetic block 251 and the electromagnetic block 252 pulls the rack 25 away from the adjusting gear 24.The drive screw rod 21 rotates to drive the transverse adjusting block 22, which in turn moves the longitudinal adjusting sleeve 23 and the adjusting gear 24 along the length of the moving seat 1 until the shaft of the adjusting gear 24 abuts against the embedded steel bar. When the pressure sensor is triggered, the controller changes the direction of the current flowing into the electromagnetic block 252 to change the magnetic poles of the electromagnetic block 252. This causes the magnetic block 251 and the electromagnetic block 252 to repel each other, pushing the rack 25 towards and meshing with the adjusting gear 24. At this time, the bidirectional cylinder 26 works to push the rack 25 to drive the adjusting gear 24, causing the longitudinal adjusting sleeve 23 to extend from the transverse adjusting block 22 and abut against the embedded steel bar, thus achieving longitudinal distance adjustment of the moving seat 1.

[0022] In the above technical solution, the motor drives the threaded rod 21 to rotate, which pulls the two sets of transverse adjustment blocks 22 closer together until the shaft of the adjustment gear 24 abuts against the pre-embedded steel bar. At this time, when the pressure sensor set at the end of the shaft of the adjustment gear 24 near the pre-embedded steel bar is pressed and reaches the preset value, the controller changes the direction of the current flowing into the electromagnetic block 252, thereby changing the magnetic pole of the electromagnetic block 252. The electromagnetic block 252 pushes the auxiliary magnetic block 251 and the rack 25 down and meshes with the adjustment gear 24. The bidirectional cylinder 26 works and pushes the rack 25 to drive the adjustment gear 24 to rotate, extending the longitudinal adjustment sleeve 23 towards the pre-embedded steel bar, adjusting the longitudinal distance between the moving seat 1 and the pre-embedded steel bar, realizing the automatic adjustment of the equipment, reducing the time and cycle of manual adjustment, facilitating the installation of wall panel components in different positions and directions, and improving work efficiency.

[0023] See attached document Figure 1 and 7 The prefabricated wall panel auxiliary positioning and installation device also includes a first centering component 3 for guiding the wall panel components to be laterally aligned with the pre-embedded steel bars. The first centering component 3 includes a support plate 31, a second connecting rod 33, and a support column 34 slidably disposed on the movable seat 1. The second connecting rod 33 is rotatably connected to the movable seat 1 and is located between the support column 34 and the support plate 31. The second connecting rod 33 is rotatably disposed on the movable seat 1. One end of the second connecting rod 33 is rotatably connected to a first connecting rod 32, and the other end of the first connecting rod 32 is rotatably connected to the bottom of the support plate 31. The end of the second connecting rod 33 away from the support plate 31 is provided with a lever 331 for moving the support column 34. The first connecting rod 32 and the second connecting rod 33 are each provided with two sets. The two sets of first connecting rods 32 are used to support the support plate 31, and a torsion spring for resetting is provided between the second connecting rod 33 and the movable seat 1.

[0024] In the above technical solution, after the wall panel component is hoisted onto the support plate 31, the support plate 31 descends and pushes the two sets of second links 33 to rotate through the two sets of first links 32, so that the ends of the two sets of second links 33 near the support column 34 are brought closer to each other, thereby pulling the two sets of support columns 34 to slide along the length direction on the movable seat 1, so as to achieve lateral centering of the wall panel component and the movable seat 1.

[0025] See attached document Figure 7-9 It is worth noting that the system also includes a second centering component 4 for adjusting the longitudinal alignment of the wall panel components and the embedded reinforcing bars. The second centering component 4 includes a fixed guide plate 41, on which a movable guide plate 43 is slidably mounted. The movable guide plate 43 is capable of vertical displacement relative to the fixed guide plate 41. The fixed guide plate 41 is provided with a first guide groove 411, which is horizontally positioned. The movable guide plate 43 is provided with a second guide groove 431 and a third guide groove 432. An adjusting column 44 is slidably mounted on the movable guide plate 43, extending into the second guide groove 431. The other side of the adjusting column 44 passes through the first guide groove 411 and extends toward the wall panel components. An elastic pressure plate 42 is elastically mounted on the fixed guide plate 41, with one end of the elastic pressure plate 42 away from the wall panel components extending into the third guide groove 432.

[0026] Specifically, guide groove 2 431 is inclined, and the end of the two sets of guide groove 2 431 that is close to each other is lower than the other side. Guide groove 2 431 is used to guide the two sets of adjusting columns 44 to approach each other. Guide groove 3 432 is inclined, and the side of guide groove 3 432 that is close to the fixed guide plate 41 is higher than the other side. Guide groove 3 432 is used to guide the movable guide plate 43 to rise when the elastic pressure plate 42 is squeezed. Only after the movable guide plate 43 rises relative to the fixed guide plate 41, guide groove 2 431 and guide groove 1 411 jointly guide the two sets of adjusting columns 44 to approach each other and clamp the wall panel component, so as to achieve longitudinal centering of the wall panel component.

[0027] Furthermore, each set of support columns 34 is provided with two sets of second centering components 4. One set of second centering components 4 is set on the support column 34, and the other set is set on the telescopic bar 341. The telescopic bar 341 is slidably installed on the support column 34, and the telescopic bar 341 is provided with an arc plate. When the two sets of support columns 34 are moved closer to each other by the lever 331, the lever 331 will rise in the vertical direction as it follows the rotation of the second connecting rod 33. This, in turn, will push the telescopic bar 341 upward in conjunction with the arc plate, thereby increasing the distance between the two sets of second centering components 4 on the same side to maintain the vertical parallelism of the components.

[0028] In the above technical solution, when the second centering component 4 follows the support column 34 and approaches and presses against both sides of the wall panel component, the elastic pressure plate 42 is compressed and retracted, and then cooperates with the guide groove three 432 to guide the movable guide plate 43 to rise. At this time, under the joint guidance of the guide groove two 431 and the guide groove one 411, the two sets of adjusting columns 44 will clamp the wall panel component to achieve longitudinal centering of the wall panel component. At the same time, the telescopic strip 341 and the support column 34 are displaced and rise, increasing the distance between the two sets of second centering components 4 on the same side to maintain the vertical parallelism of the component, prevent the bending deformation of the embedded steel bars during hole insertion, and simultaneously calibrate the horizontality and verticality of the wall panel during hole insertion to improve installation accuracy and overall structural stability.

[0029] Working principle: First, the movable seat 1 is pushed close to the pre-embedded steel bar, and the distance between the movable seat 1 and the pre-embedded steel bar is less than the maximum stroke distance of the longitudinal adjusting sleeve 23. The drive threaded rod 21 is rotated to pull the two sets of transverse adjusting blocks 22 to move and move closer to each other until the shaft of the adjusting gear 24 abuts against the pre-embedded steel bar. At this time, the movable seat 1 is positioned laterally. When the pressure sensor on the shaft of the adjusting gear 24 is pressed and reaches the preset value, it changes the magnetic pole of the electromagnetic block 252 in conjunction with the controller. At this time, the electromagnetic block 252 and the auxiliary magnetic block 251 repel each other. The electromagnetic block 252 pushes the auxiliary magnetic block 251 and the rack 25 down and meshes with the adjusting gear 24. In conjunction with the bidirectional cylinder 26, the rack 25 is pushed to drive the adjusting gear 24 to rotate. The longitudinal adjusting sleeve 23 extends towards the pre-embedded steel bar and abuts against it, thus positioning the movable seat 1 longitudinally. Then, the hole is aligned. After the wall panel component is hoisted onto the support plate 31, the... After the wall panel component is pressed onto the support plate 31, the support plate 31 descends and pushes the two sets of second links 33 along the pivot on the movable seat 1 through the two sets of first links 32. This causes the ends of the two sets of second links 33 near the support column 34 to move closer to each other, thereby pulling the two sets of support columns 34 to slide along the length direction on the movable seat 1, achieving lateral alignment between the wall panel component and the movable seat 1. Finally, when the second alignment component 4 follows the support column 34 to approach and press the wall panel component, the elastic pressure plate 42 is compressed back and, in conjunction with the guide groove 3 432, guides the movable guide plate 43 to rise. Under the combined guidance of the guide groove 2 431 and the guide groove 1 411, the two sets of pressing columns 44 will gradually clamp the wall panel component, achieving longitudinal alignment of the wall panel component. At the same time, the telescopic strip 341 is displaced on the support column 34, increasing the distance between the two sets of second alignment components 4 on the same side to maintain the vertical parallelism of the component.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
