Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to an auxiliary positioning device for hoisting precast wall panels. Background Technology

[0002] The application of precast wall panels is becoming increasingly widespread in building construction. These panels are prefabricated in a factory and then transported to the construction site for hoisting and installation. However, accurately positioning the precast wall panels in their designated locations during hoisting is a crucial issue.

[0003] In prefabricated buildings, precast wall panels need to be hoisted and connected to the pre-reserved reinforcing bars in the underlying structure. Currently, during hoisting, the alignment of the pre-drilled holes at the bottom of the wall panel with the reinforcing bars is usually observed manually, and the position of the precast wall panel is manually adjusted. However, this positioning method relies on manual observation and adjustment, making it difficult to guarantee the precise alignment of the precast wall panel with the intended installation position. The hoisting process requires multiple adjustments to the precast wall panel position, which is cumbersome, time-consuming, and labor-intensive, hindering the rapid positioning and installation of precast wall panels. Therefore, an auxiliary positioning device for hoisting precast wall panels is needed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing methods, the purpose of this utility model is to provide an auxiliary positioning device for the hoisting of precast wall panels, which solves the problems of inaccurate positioning and low installation efficiency in existing hoisting methods. This device achieves rapid and accurate positioning of wall panels through mechanical guidance, thereby improving construction efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A precast wall panel hoisting auxiliary positioning device includes a base, a fixed frame vertically fixed on the upper left side of the base, two sets of guide positioning mechanisms symmetrically arranged on the outer side of the fixed frame, an auxiliary positioning component on the lower side of the guide positioning mechanism, heavy-duty casters installed at the bottom of the base near the four corners, two sets of hydraulic support components symmetrically arranged on the front and rear sides of the base, a hydraulic pump station installed on the upper side of the base, and a handle fixed on the upper surface of the base near the right edge.

[0007] The guiding and positioning mechanism includes a fixed base plate, which is vertically fixed to the left side of the fixed frame. Side plates are fixed at both edges of the left side of the fixed base plate. Two sets of guide plates are provided between the two sets of side plates. A first screw and several sets of first guide rods are provided inside the two sets of guide plates. A first handle is installed at the outer end of the first screw.

[0008] Furthermore, the two sets of guide plates are identical in specifications, both being L-shaped with their short sides facing outwards, and the two sets of guide plates together form a T-shaped structure.

[0009] Furthermore, the first screw passes through two sets of guide plates and its two ends are rotatably connected to the side plates on both sides. Both sets of guide plates are adjustablely connected to the first screw via threads. The first screw has two sets of threads with opposite helical directions on its left and right sides.

[0010] Furthermore, the first guide rod is welded and fixed to the side plate at both ends, and the guide plate is sleeved on the first guide rod and slidably connected to it.

[0011] Furthermore, the auxiliary positioning component includes a right-angle pressure plate, a second handle, and a second screw. The right-angle pressure plate is located on the lower left side of the base. A second screw is threaded through the left end of the base. The lower end of the second screw is rotatably connected to the right-angle pressure plate via a connector. A second handle is installed on the upper end of the second screw. Two sets of second guide rods are symmetrically arranged on the upper surface of the right-angle pressure plate.

[0012] Furthermore, the hydraulic support assembly includes a hydraulic cylinder, a support plate, and a foot plate. The support plate is fixed at the outer corner of the base. A hydraulic cylinder is vertically fixed inside the support plate. The hydraulic cylinder is connected to a hydraulic pump station through a hydraulic oil pipe. The telescopic end of the hydraulic cylinder faces downward, and a foot plate is installed on it.

[0013] Furthermore, each foot plate has several sets of positioning holes for installing expansion bolts inside;

[0014] The footplate is equipped with anti-slip rubber pads.

[0015] Furthermore, two sets of diagonal braces are provided between the right end face of the fixed frame and the base, and the diagonal braces are fixedly connected to the fixed frame and the base by welding.

Detailed Implementation

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] Example:

[0032] like Figures 1 to 6 As shown, a precast wall panel hoisting auxiliary positioning device includes a base 5. A fixed frame 1 is vertically fixed on the upper left side of the base 5. Two sets of guide positioning mechanisms 2 are symmetrically arranged on the outer side of the fixed frame 1. An auxiliary positioning component 3 is provided on the lower side of the guide positioning mechanism 2. Heavy-duty casters 10 are installed at the bottom of the base 5 near the four corners. Two sets of hydraulic support components 4 are symmetrically arranged on the front and rear sides of the base 5. A hydraulic pump station 9 is installed on the upper side of the base 5. A handle 7 is fixed on the upper surface of the base 5 near the right edge.

[0033] The guiding and positioning mechanism 2 includes a fixed base plate 21, which is vertically fixed to the left side of the fixed frame 1. Side plates 22 are fixed at both edges of the left side of the fixed base plate 21. Two sets of guide plates 23 are provided between the two sets of side plates 22. A first screw 24 and several sets of first guide rods 26 are passed through the two sets of guide plates 23. A first handle 25 is installed at the outer end of the first screw 24. This design solves the problem that the positioning of the precast wall panel during hoisting relies on manual observation and adjustment, which makes it difficult to ensure the precise alignment of the precast wall panel with the predetermined installation position. The position of the precast wall panel needs to be adjusted multiple times during hoisting, which is cumbersome, consumes a lot of time and manpower, and makes it difficult to achieve rapid positioning of the precast wall panel.

[0034] In this embodiment, the two sets of guide plates 23 are identical in size, both being L-shaped structures with their short sides facing outwards. When the two sets of guide plates 23 are attached together, the overall structure is T-shaped.

[0035] It should be noted that the precast wall panel has two sets of sliding grooves that are adapted to the guide plates 23 on the guide positioning mechanism 2. The cross-section of the grooves is T-shaped, and the length is the same as that of the guide plates 23. The bottom opening of the grooves is located at the bottom of the precast wall panel, and the opening width of the grooves is greater than the total width of the two sets of guide plates 23.

[0036] In this embodiment, the first screw 24 passes through two sets of guide plates 23 and its two ends are rotatably connected to the side plates 22 on both sides. Both sets of guide plates 23 are adjustablely connected to the first screw 24 via threads. The first screw 24 has two sets of threads with opposite helical directions on its left and right sides. The first screw 24 adopts a positive and negative thread design, and its two ends are connected to the side plates 22 via bearings. When the first handle 25 is rotated, the two sets of guide plates 23 move synchronously in opposite directions along the second guide support rod 34 to achieve rapid opening and closing adjustment.

[0037] In this embodiment, the first guide rod 26 is welded and fixed to the side plate 22 at both ends, and the guide plate 23 is sleeved on the first guide rod 26 and slidably connected to it. The first guide rod 26 provides anti-torsional support, ensuring that the guide plate 23 moves parallel without swaying and guaranteeing the stability of the movement.

[0038] In this embodiment, the auxiliary positioning component 3 includes a right-angle pressure plate 31, a second handle 32, and a second screw 33. The right-angle pressure plate 31 is located on the lower left side of the base 5. The second screw 33 is threaded through the left end of the base 5. The lower end of the second screw 33 is rotatably connected to the right-angle pressure plate 31 via a connector. The second handle 32 is installed on the upper end of the second screw 33. Two sets of second guide rods 34 are symmetrically arranged on the upper surface of the right-angle pressure plate 31. The two sets of second guide rods 34 pass through the base 5 and are slidably connected to it. The auxiliary positioning component 3 can assist in positioning the device, ensuring the overall positioning accuracy of the device. The right-angle pressure plate 31 is used to fit the edge line of the prefabricated wall panel on the mounting surface to achieve precise positioning of the device.

[0039] In this embodiment, the hydraulic support assembly 4 includes a hydraulic cylinder 41, a support plate 42, and a foot plate 43. The support plate 42 is fixed at the outer corner of the base 5, and the hydraulic cylinder 41 is vertically fixed inside the support plate 42. The hydraulic cylinder 41 is connected to the hydraulic pump station 9 through a hydraulic oil pipe. The telescopic end of the hydraulic cylinder 41 faces downward, and the foot plate 43 is installed on it. The hydraulic support assembly 4 provides hydraulic support for the device, ensuring the overall stability of the device during operation.

[0040] In this embodiment, the foot plate 43 is provided with several sets of positioning holes 45 for installing expansion bolts. The positioning holes 45 can be used to fix the foot plate 43 to the mounting surface of the precast wall panel, thereby further ensuring the stability of the device.

[0041] The foot plate 43 is equipped with anti-slip rubber pads 44, which can increase the friction between the foot plate 43 and the precast wall panel mounting surface and prevent the device from shifting or shaking.

[0042] In this embodiment, two sets of diagonal braces 8 are provided between the right end face of the fixed frame 1 and the base 5. The diagonal braces 8 are fixedly connected to the fixed frame 1 and the base 5 by welding. The two sets of diagonal braces 8 enhance the structural strength between the fixed frame 1 and the base 5, ensuring the stability of the fixed frame 1. The diagonal braces 8 work with the fixed frame 1 to form a triangular force-bearing structure, which significantly improves the overall rigidity.

[0043] In this embodiment, the base 5 is also provided with multiple sets of counterweights 6. The counterweights 6 can lower the center of gravity of the device and improve the stability of the device during operation.

[0044] Working principle of this precast wall panel hoisting auxiliary positioning device:

[0045] In actual use, first, push the device using the handle 7 to move it to the precast wall panel installation position, ensuring that one side of the guide positioning mechanism 2 on the device faces the precast wall panel installation position. Then, rotate the second handle to adjust the position of the right-angle pressure plate 31, moving it downwards until its lower end is flush with the bottom surface. Fine-tune the device position to align the lower end of the right-angle pressure plate 31 with the edge line on the precast wall panel installation position. Next, start the hydraulic pump station 9, which controls the four sets of hydraulic cylinders 41 to extend downwards. The hydraulic cylinders 41 drive the foot plate 43 downwards, supporting the entire device and ensuring its overall stability.

[0046] The precast wall panel is then hoisted and moved above the guide positioning mechanism 2. The panel is slowly released and lowered until the bottom of the panel is approximately 5cm from the top of the guide plate 23. The position of the panel is then adjusted so that the groove on it aligns with the top of the guide plate 23. The panel is then released, allowing the groove to engage with the guide plate 23. The guide plate 23, in conjunction with the groove, guides the precast wall panel to the correct position. At this point, the holes at the bottom of the panel are perfectly aligned with the reinforcing bars at the installation position. The panel is then continuously released, moving vertically downwards under the constraint of the guide plate 23 until it is fully positioned at the installation position, thus achieving rapid positioning of the precast wall panel.

[0047] After the precast wall panel is positioned, rotate the first handle 25, which drives the first screw 24 to rotate. The rotation of the first screw 24 drives the guide plates 23 on both sides to move closer to the middle until they fit together to form a T-shaped structure. At this time, the overall width of the two sets of guide plates 23 is less than the width of the groove opening on the precast wall panel. Then move the device outward to disengage the guide plates 23 from the groove on the precast wall panel.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
