Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a construction assembly platform. Background Technology

[0002] Construction is a production activity carried out by people using various building materials and machinery according to specific design blueprints within a certain space and time to build various building products. It includes the entire production process from construction preparation and groundbreaking to project completion and acceptance. This process involves construction preparation, construction organization design and management, earthwork engineering, blasting engineering, foundation engineering, reinforcement engineering, formwork engineering, scaffolding engineering, concrete engineering, prestressed concrete engineering, masonry engineering, steel structure engineering, timber structure engineering, structural installation engineering, etc. During the construction process, assembly platforms are used for construction at heights.

[0003] The prior art patent CN221878741U discloses an assembly platform for prefabricated building construction. This platform, consisting of a base plate, protective structure, vertical protective columns, horizontal protective columns, support plate, climbing structure, mounting rods, mounting ropes, climbing ladder ropes, buffer structure, mounting plate, two bolts, dampers, buffer springs, rotating support rods, casters, fixing structure, screw holes, fixing grooves, threaded through holes, one bolt, folding groove, and a rotating shaft, allows for folding and storage. The buffer structure enhances the platform's cushioning performance during use. However, in actual installation, the support plate needs to be raised to a high position and then installed using multiple bolts. Repeatedly installing and removing multiple bolts increases the labor intensity for workers. Furthermore, if the support plate is too high, it increases the difficulty of rotating multiple bolts; if it is too low, it affects the overall support height, making it inconvenient to use. Additionally, during use, the base plate contacts the ground via the casters, resulting in poor stability and further hindering usability. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a construction assembly platform. This solves the problem that the support plate needs to be lifted to a high position and then installed using multiple bolts, which easily increases the labor intensity of workers. Furthermore, when the support plate is too high, it becomes difficult to rotate multiple bolts, while if it is too low, it affects the overall support height and is inconvenient to use. Additionally, during use, the base plate contacts the ground via casters, resulting in poor stability and inconvenience.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a construction assembly platform, including a base, an installation frame detachably mounted on the top of the base by fixing bolts, a support plate provided above the base, and a lifting and fixing mechanism adapted to the support plate being provided on both the base and the installation frame.

[0006] The lifting and fixing mechanism includes two trapezoidal lifting plates disposed below the base. Four fixing boxes are installed on the top of the mounting frame. Two fixing rods are installed on the inner walls of each of the four fixing boxes. An L-shaped block is slidably sleeved on each pair of matching fixing rods. An I-shaped block is installed on the side of each of the four L-shaped blocks. Guide columns are installed on the top inner walls of each of the four L-shaped blocks. Four guide holes that match the guide columns are opened on the top of the support plate. Four limiting plates are disposed above the base. A drive assembly for moving the four L-shaped blocks, the four limiting plates, and the two trapezoidal lifting plates is disposed on the base and the four L-shaped blocks.

[0007] Preferably, the drive assembly includes a motor mounted on the side of the base. The top of the base has two grooves, and a bidirectional lead screw is rotatably mounted on the inner wall of each of the two grooves. One end of one of the bidirectional lead screws extends outside the base and is mounted on the output shaft of the motor. The two bidirectional lead screws are fitted together via a transmission unit. Two threaded blocks are threaded onto each of the two bidirectional lead screws. An inclined block is rotatably mounted on the top of each of the four threaded blocks. The other end of each of the four inclined blocks is rotatably mounted on the bottom of each of the four L-shaped blocks. A sliding groove is provided on the top of each of the four L-shaped blocks. A sliding rod is mounted on the inner wall of each of the four sliding grooves. An L-shaped sliding plate is slidably fitted onto each of the four sliding rods. A limiting plate is mounted on the side of the L-shaped sliding plate. A trapezoidal moving block is mounted on the side of the L-shaped sliding plate away from the limiting plate. A trapezoidal pressing block, adapted to the trapezoidal moving block, is mounted on the inner wall of the side of each of the four fixing boxes. An elastic unit is provided on the side of each of the four L-shaped sliding plates. The four threaded blocks cause the two trapezoidal lifting plates to move up and down via the pressing unit.

[0008] Preferably, the extrusion unit includes connecting blocks respectively installed at the bottom of the four threaded blocks. The bottom of the base has four through holes. The bottom of the four connecting blocks passes through the four through holes and each is equipped with a movable block. The top of the base has two lifting holes. Lifting blocks are slidably installed on each of the two lifting holes. The two sides of the two lifting blocks, which are far apart from each other, abut against the inner side walls of the two lifting holes and the inner side walls of the mounting frame, respectively. Two trapezoidal lifting plates are respectively installed at the bottom of the two lifting blocks. Fixed plates are installed on the sides of the two lifting blocks. Trapezoidal movable plates are installed at the bottom of the two fixed plates. A U-shaped plate is installed on the top of every two threaded blocks. The top of the base has movable holes adapted to the trapezoidal movable plates.

[0009] Preferably, the elastic unit includes a spring installed on the side of the L-shaped slide plate, and the other end of the spring is installed on the inner wall of the side wall of the slide groove.

[0010] Preferably, the transmission unit includes sprockets respectively sleeved on the two bidirectional lead screws, with a chain meshing on both sprockets, and fixing holes adapted to the chain are opened on the inner walls of the two adjacent sides of the grooves, and protective plates are installed on the inner walls of the two grooves.

[0011] Preferably, the base is equipped with four casters at its bottom, and each of the four limiting plates is rotatably equipped with multiple ball bearings at its bottom.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention uses guide columns and guide holes to limit the support plate, preventing it from moving horizontally. Then, a motor, a two-way lead screw, a threaded block, and an inclined block allow the L-shaped block to rise. As the L-shaped block rises, it moves the limiting plate via an L-shaped sliding plate, a trapezoidal moving block, a trapezoidal pressing block, and a spring, thereby limiting or removing the limit on the support plate. This automatically fixes or removes the fixation of the support plate during lifting, reducing the lifting height during installation and effectively lowering the labor intensity of workers. When the threaded block moves to adjust the height of the support plate, its movement, through a connecting block and a movable block, causes the trapezoidal lifting plate to contact the ground, thus fixing the base and increasing the stress area for better stability.

[0014] This utility model, through the arrangement of a fixed plate, a trapezoidal movable plate, and a U-shaped plate, facilitates the resetting of the trapezoidal lifting plate while the supporting station plate descends, thereby preventing the trapezoidal lifting plate from contacting the ground and avoiding any impact on the movement of the base. The ball bearing arrangement facilitates the movement of the limiting plate, preventing direct contact between the limiting plate and the supporting station plate, which could cause wear and affect subsequent use.

[0022] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0023] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Attached Figure 6 The present invention will be further described below.

[0024] The construction assembly platform includes a base 1, an installation frame 2 that is detachably installed on the top of the base 1 by fixing bolts, a support plate 4 that is provided above the base 1, and a lifting and fixing mechanism that is compatible with the support plate 4 is provided on both the base 1 and the installation frame 2.

[0025] The lifting and fixing mechanism includes two trapezoidal lifting plates 20 located below the base 1. Four fixing boxes 3 are installed on the top of the mounting frame 2. Two fixing rods are installed on the inner walls of the four fixing boxes 3. An L-shaped block 10 is slidably sleeved on each pair of matching fixing rods. I-shaped blocks are installed on the sides of the four L-shaped blocks 10. Guide columns 5 are installed on the top inner walls of the four L-shaped blocks 10. Four guide holes that match the guide columns 5 are opened on the top of the support plate 4. Four limiting plates 14 are set above the base 1. A drive assembly that moves the four L-shaped blocks 10, the four limiting plates 14, and the two trapezoidal lifting plates 20 is set on the base 1 and the four L-shaped blocks 10.

[0026] With the above structure, during use, the support plate 4 is placed on the L-shaped block 10, and the guide column 5 is placed in the guide hole, thereby limiting the support plate 4 and preventing it from moving horizontally. Then, the L-shaped block 10 is raised by the drive component. The rise of the L-shaped block 10 will cause the limiting plate 14 to move through the drive component, thereby limiting or unlimiting the support plate 4. Thus, during lifting, the support plate 4 is automatically fixed or unfixed, while reducing the lifting height of the support plate 4 during installation, effectively reducing the labor intensity of the workers. At the same time, when the height of the support plate 4 is adjusted, the drive component will make the trapezoidal lifting plate 20 contact the ground, thereby fixing the base 1 and increasing the force-bearing area, resulting in better stability.

[0027] like Figure 3 - Figure 6 As shown, the drive assembly includes a motor 6 mounted on the side of the mounting base 1. Two grooves 24 are formed on the top of the base 1. A bidirectional lead screw 7 is rotatably mounted on the inner wall of each groove 24. One end of one bidirectional lead screw 7 extends outside the base 1 and is mounted on the output shaft of the motor 6. The two bidirectional lead screws 7 are mounted in conjunction with a transmission unit. Two threaded blocks 8 are threaded onto each of the two bidirectional lead screws 7. An inclined block 9 is rotatably mounted on the top of each of the four threaded blocks 8. The other ends of the four inclined blocks 9 are rotatably mounted on the bottom of four L-shaped blocks 10. Specifically, the inclined blocks 9 are rotated by limiting bolts. The four L-shaped blocks 10 are mounted on the bottom of the L-shaped blocks 10. Each of the four L-shaped blocks 10 has a groove on its top. Each of the four grooves has a sliding rod installed on its inner wall. Each of the four sliding rods has an L-shaped slide plate 11 slidably fitted on its inner wall. Each of the four slide plates 11 has a limiting plate 14 installed on its side. Each of the four L-shaped slide plates 11 has a trapezoidal moving block 12 installed on its side away from the limiting plate 14. Each of the four fixed boxes 3 has a trapezoidal pressing block 13 that matches the trapezoidal moving block 12 installed on its inner wall. Each of the four L-shaped slide plates 11 has an elastic unit on its side. Each of the four threaded blocks 8 causes the two trapezoidal lifting plates 20 to move up and down through the pressing unit.

[0028] In this design, the motor 6, bidirectional lead screw 7, threaded block 8, inclined block 9, slide bar, L-shaped slide plate 11, trapezoidal moving block 12, and trapezoidal pressing block 13 are designed to facilitate the fixing or unfixing of the support plate 4 while the L-shaped block 10 is moving up and down.

[0029] Specifically, the L-shaped block 10 fixes the support plate 4 during lifting, eliminating the need for workers to operate multiple bolts with tools, thus reducing the labor intensity of workers.

[0030] like Figure 2 , Figure 3 and Figure 6As shown, the extrusion unit includes connecting blocks installed at the bottom of four threaded blocks 8. The bottom of the base 1 has four through holes 25. The bottom of the four connecting blocks passes through the four through holes 25 and each is equipped with a movable block 18. The top of the base 1 has two lifting holes. Lifting blocks 19 are slidably installed on each of the two lifting holes. The two sides of the two lifting blocks 19, which are far apart from each other, abut against the inner side walls of the two lifting holes and the inner side walls of the mounting frame 2. Two trapezoidal lifting plates 20 are installed at the bottom of the two lifting blocks 19. Fixed plates 21 are installed on the sides of the two lifting blocks 19. Trapezoidal movable plates 22 are installed at the bottom of the two fixed plates 21. A U-shaped plate 23 is installed on the top of every two threaded blocks 8. The top of the base 1 has movable holes that are adapted to the trapezoidal movable plates 22.

[0031] In this design, the connection block, movable block 18, lifting block 19, fixed plate 21, trapezoidal movable plate 22 and U-shaped plate 23 are arranged to facilitate the vertical movement of the trapezoidal lifting plate 20 while the height of the support station plate 4 is adjusted.

[0032] Specifically, by moving the trapezoidal lifting plate 20 along with the support plate 4, the trapezoidal lifting plate 20 can contact the ground during use, thereby fixing the base 1 and increasing the force-bearing area for better stability. When not in use, the trapezoidal lifting plate 20 can be raised to avoid affecting the movement of the base 1.

[0033] like Figure 5 As shown, the elastic unit includes a spring 15 installed on the side of the L-shaped slide plate 11, and the other end of the spring 15 is installed on the inner wall of the side wall of the slide groove.

[0034] In this design, the spring 15 facilitates the reset of the L-shaped slide plate 11.

[0035] Specifically, by resetting the L-shaped sliding plate 11, the limiting plate 14 can be reset, thereby canceling the limitation on the support plate 4.

[0036] like Figure 6 As shown, the transmission unit includes sprockets 16 respectively sleeved on two bidirectional lead screws 7, and chains 17 are meshed on the two sprockets 16. The inner walls of the two grooves 24 that are close to each other are provided with fixing holes that are adapted to the chains 17. Protective plates 26 are installed on the inner walls of the two grooves 24.

[0037] In this design, the sprocket 16, chain 17 and protective plate 26 facilitate the simultaneous rotation of the two bidirectional lead screws 7.

[0038] Specifically, by rotating the two bidirectional lead screws 7 simultaneously, the four L-shaped blocks 10 can move and rise simultaneously. The protective plate 26 facilitates protection of the sprocket 16 and chain 17 from the top.

[0039] like Figure 1 and Figure 5 As shown, four casters are installed at the bottom of the base 1, and multiple ball bearings are rotatably installed at the bottom of the four limit plates 14.

[0040] In this design, the universal wheels facilitate the movement of the base 1, and the ball bearings facilitate the movement of the limiting plate 14, thus preventing the limiting plate 14 from directly contacting the support plate 4 and causing wear that would affect subsequent use.

[0041] In summary: When using this utility model, firstly, the lifting block 19 is moved into the lifting hole, then the mounting frame 2 is installed on the top of the base 1. Once fixed, the inclined block 9 is rotated and installed on the bottom of the four L-shaped blocks 10. When installed, the support plate 4 is placed on the four L-shaped blocks 10 and the I-shaped block. At this time, the guide post 5 is inserted into the guide hole, thereby limiting the support plate 4 so that it cannot move horizontally. Then, the motor 6 is started. The output of the motor 6 will cause one of the bidirectional lead screws 7 to rotate. The rotation of one of the bidirectional lead screws 7 will cause... One of the sprockets 16 rotates, which in turn causes the other sprocket 16 to rotate via chain 17. The rotation of the other sprocket 16 causes the other double-acting lead screw 7 to rotate. The rotation of the two double-acting lead screws 7 causes the four threaded blocks 8 to move away from each other. This movement of the four threaded blocks 8, through the wedge block 9, applies a force to the four L-shaped blocks 10. Under the action of the fixed rod, the four L-shaped blocks 10 move upward. This upward movement of the four L-shaped blocks 10 causes the supporting plate 4 and the sliding rod to move upward. The upward movement of the sliding rod causes the L-shaped sliding plate 1 to move upward. 1. Moving upwards, the L-shaped sliding plate 11 causes the trapezoidal moving block 12 and the limiting plate 14 to move upwards. When the trapezoidal moving block 12 contacts the trapezoidal pressing block 13, the trapezoidal moving block 12 continues to move upwards and will be compressed and move. The movement of the trapezoidal moving block 12 causes the L-shaped sliding plate 11 to move, and the movement of the L-shaped sliding plate 11 causes the limiting plate 14 to move, thereby limiting the support station plate 4. When it needs to be removed, the motor 6 outputs in reverse. The reverse output of the motor 6 causes the two bidirectional lead screws 7 to rotate in reverse. The movement causes the four L-shaped blocks 10 to descend. The descent of the L-shaped blocks 10 causes the trapezoidal moving block 12 to descend via the L-shaped sliding plate 11. When the trapezoidal moving block 12 is no longer in contact with the trapezoidal pressing block 13, the L-shaped sliding plate 11 will reset under the action of the spring 15. The reset of the L-shaped sliding plate 11 will reset the limiting plate 14, thereby canceling the limitation on the support plate 4. Thus, during the lifting process, the support plate 4 is automatically fixed or unfixed, while reducing the lifting height of the support plate 4 during installation, effectively reducing the labor intensity of the workers.

[0042] When the threaded block 8 moves, it drives the connecting block and U-shaped plate 23 to move. The movement of the connecting block causes the movable block 18 to move. When the limiting plate 14 limits the support plate 4, the movable block 18 contacts the inclined surface of the trapezoidal lifting plate 20, and the U-shaped plate 23 contacts the inclined surface of the trapezoidal movable plate 22. Then, the motor 6 is started. The motor 6 continues to output power, causing the threaded block 8 to continue moving. The continued movement of the threaded block 8 causes the L-shaped block 10 to continue rising, thereby adjusting the height of the support plate 4. At the same time, the continued movement of the threaded block 8 causes the movable block 18 and U-shaped plate 23 to move. The continued movement of the movable block 18 compresses the trapezoidal movable plate 22. The U-shaped lifting plate 20 lowers the trapezoidal lifting plate 20, and the movement of the U-shaped plate 23 cancels the compression of the trapezoidal movable plate 22. When the movable block 18 contacts the top of the trapezoidal lifting plate 20, the trapezoidal lifting plate 20 contacts the ground. At this time, the movable block 18 and the trapezoidal lifting plate 20 provide auxiliary limiting support for the base 1, thereby fixing the base 1 and increasing the force-bearing area for better stability. When the threaded block 8 resets, the movable block 18 cancels the compression of the trapezoidal lifting plate 20, while the U-shaped plate 23 compresses the trapezoidal movable plate 22, causing the trapezoidal lifting plate 20 to rise, thus avoiding affecting the movement of the base 1.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
