Description

Technical Field

[0001] This utility model relates to the field of construction supports, and more particularly to adjustable supports for building construction. Background Technology

[0002] In construction, adjustable scaffolding is a temporary support system that can flexibly adjust its height, span, or structure. It is mainly used to support construction workers, materials, or formwork, adapting to the needs of different building heights and complex working conditions. It combines the stability of traditional scaffolding with the flexibility of adjustable supports, making it an important tool for improving efficiency and safety in modern construction.

[0003] Existing adjustable scaffolding for building construction typically requires adjusting the height of multiple supports one by one and fixing them by tightening bolts or pins. This decentralized adjustment method is not only cumbersome and time-consuming, but also requires repeated measurement of the height of each support to ensure levelness, making it difficult to achieve quick and accurate adjustments. It is particularly inefficient in construction scenarios that require frequent adjustments.

[0004] Therefore, in view of the problem that the existing adjustable scaffolds for building construction require adjusting and positioning multiple supports separately when adjusting the height, which is a complicated operation and not convenient for quick debugging, there is an urgent need to design a new type of adjustable scaffold for building construction. Utility Model Content

[0005] To overcome the problem that existing adjustable scaffolding for building construction requires adjusting and positioning multiple supports separately when adjusting the height, which is a cumbersome operation and not convenient for quick debugging.

[0006] The technical solution of this utility model is as follows: an adjustable support for building construction, including a base plate; it also includes a first bevel gear, a threaded pipe, a lead screw, a first bearing seat, a first drive shaft, a second bevel gear, a second bearing seat, a second drive shaft, a third bevel gear, and a fourth bevel gear. The first bevel gear is rotatably connected to the corners of the upper surface of the base plate. A threaded pipe is installed on the upper surface of the first bevel gear, and a lead screw is connected to the inner surface of the threaded pipe. A construction platform is provided at the top of the lead screw. First bearing seats are provided on both the front and rear sides of the upper surface of the base plate. A first drive shaft is connected to the inner surface of each of the two first bearing seats. Second bevel gears are provided at both ends of each of the two first drive shafts, and the second bevel gears mesh with their corresponding first bevel gears. A second bearing seat is installed at the middle right side of the upper surface of the base plate. A second drive shaft is connected to the inner surface of the second bearing seat. Third bevel gears are provided at both ends of the second drive shaft. Fourth bevel gears are provided on the outer surfaces of the two first drive shafts near the third bevel gears, and the third bevel gears mesh with the fourth bevel gears.

[0007] Preferably, by setting a second bearing seat, the second drive shaft can rotate, thereby driving two third bevel gears to rotate. When the third bevel gears rotate, they can drive the fourth bevel gear meshing with them to rotate. Thus, with the cooperation of the first bearing seat, the first drive shaft can rotate. The first drive shaft can drive the second bevel gears at both ends to rotate. The first bevel gears meshing with the second bevel gears can rotate, thereby driving four threaded tubes to rotate. When the threaded tubes rotate, the screws that are engaged with their threads can move up and down, thereby realizing the lifting and lowering of the construction platform. When adjusting the lifting platform, only the second drive shaft needs to be rotated, without the need to adjust multiple support rods, simplifying the operation steps. This solves the problem that existing adjustable supports for building construction require adjusting and positioning multiple support rods separately when adjusting the height, which is a cumbersome operation step and not convenient for quick debugging.

[0008] Preferably, a driven gear is installed on the outer surface of the second drive shaft at the front position, and a motor seat is provided on the upper surface of the base plate on the right front side of the second bearing seat. A drive motor is installed on the upper surface of the motor seat, and the output end of the drive motor is connected to a driving gear, which meshes with the driven gear.

[0009] Preferably, fixing bolts are provided at the corners of the upper surface of the motor base, and the motor base is fixed to the base plate by fixing bolts.

[0010] Preferably, each of the four lead screws has a positioning seat located on the upper part of its outer surface, and each of the four positioning seats is connected to a positioning rod between each other.

[0011] Preferably, the bottom surface of the base plate is provided with threaded sleeves near the four sides, the inner surface of the threaded sleeves is connected to a screw, and the bottom of the screw is provided with a washer.

[0012] Preferably, casters are provided at the corners of the bottom surface of the base plate, and the casters are fixed to the base plate with screws.

[0013] Preferably, a fence is installed near the edge of the upper surface of the construction platform, and a telescopic ladder is provided on the front surface of the construction platform.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a second bearing seat, the second drive shaft can rotate with the cooperation of the second bearing seat, thereby driving the two third bevel gears to rotate. The third bevel gears will drive the fourth bevel gear meshing with them to rotate, thereby causing the first drive shaft to rotate with the cooperation of the first bearing seat. The first drive shaft can drive the second bevel gears at both ends to rotate, thereby driving the first bevel gear meshing with them to rotate, thus driving the four threaded tubes to rotate. When the threaded tubes rotate, the screws that are engaged with their threads can move up and down, thereby realizing the lifting and lowering of the construction platform. When adjusting the lifting platform, only the second drive shaft needs to be rotated, without the need to adjust multiple support rods, simplifying the operation steps. This solves the problem that existing adjustable supports for building construction require adjusting and positioning multiple support rods separately when adjusting the height, which is a cumbersome operation step and not convenient for quick debugging.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of an adjustable support for building construction, including a base plate 1; it also includes a first bevel gear 2, a threaded pipe 3, a lead screw 4, a first bearing seat 5, a first drive shaft 6, a second bevel gear 7, a second bearing seat 8, a second drive shaft 9, a third bevel gear 10, and a fourth bevel gear 25. The first bevel gear 2 is rotatably connected to the corners of the upper surface of the base plate 1. A threaded pipe 3 is installed on the upper surface of the first bevel gear 2, and a lead screw 4 is connected to the inner surface of the threaded pipe 3. A construction platform 22 is provided at the top of the lead screw 4. First bearing seats 5 are provided on both the front and rear sides of the upper surface of the base plate 1. A first drive shaft 6 is connected to the inner surface of each of the two first bearing seats 5. Second bevel gears 7 are provided at both ends of each of the two first drive shafts 6, and the second bevel gears 7 mesh with the corresponding first bevel gears 2. A second bearing seat 8 is installed at the middle right side of the upper surface of the base plate 1, and a second drive shaft 9 is connected to the inner surface of the second bearing seat 8. The second drive shaft 9 is connected to the front and rear sides of the second drive shaft 9. A third bevel gear 10 is provided at one end, and a fourth bevel gear 25 is provided on the outer surface of each of the two first drive shafts 6 near the third bevel gear 10. The third bevel gear 10 and the fourth bevel gear 25 mesh with each other. By providing a second bearing seat 8, the second drive shaft 9 can rotate, thereby driving the two third bevel gears 10 to rotate. When the third bevel gear 10 rotates, it can drive the fourth bevel gear 25 meshing with it to rotate. Thus, with the cooperation of the first bearing seat 5, it can drive the first drive shaft 6 to rotate. The first drive shaft 6 can drive the second bevel gears 7 at both ends to rotate. The first bevel gear 2 meshing with the second bevel gear 7 can rotate, thereby driving the four threaded tubes 3 to rotate. When the threaded tubes 3 rotate, the screws 4 that are threaded with them can move up and down, thereby realizing the lifting and lowering of the construction platform 22. When adjusting the lifting platform, only the second drive shaft 9 needs to be rotated, without the need to adjust multiple support rods, simplifying the operation steps.

[0023] Please see Figures 1-3In this embodiment, a driven gear 11 is mounted on the front of the outer surface of the second transmission shaft 9. A motor seat 12 is located on the upper surface of the base plate 1, on the right front side of the second bearing seat 8. A drive motor 13 is mounted on the upper surface of the motor seat 12. The output end of the drive motor 13 is connected to a driving gear 14, which meshes with the driven gear 11. By setting the drive motor 13, its output end can drive the driving gear 14 to rotate during operation. When the driving gear 14 rotates, it can drive the driven gear 11 meshing with it to rotate, thereby driving the second transmission shaft 9 to rotate, thus achieving... For the automatic adjustment of the entire device, fixing bolts 15 are provided at the corners of the upper surface of the motor base 12. The motor base 12 is fixed to the base plate 1 by fixing bolts 15. By setting fixing bolts 15, the fixing strength between the motor base 12 and the base plate 1 can be improved and loosening can be prevented. Positioning seats 16 are provided at the upper position of the outer surface of the four lead screws 4. Positioning rods 17 are connected between each pair of the four positioning seats 16. By setting positioning seats 16 and positioning rods 17, the lead screws 4 can be limited, preventing the threaded tube 3 from driving the lead screws 4 to rotate when rotating, which would reduce the transmission efficiency.

[0024] Please see Figures 1-4 In this embodiment, threaded sleeves 18 are provided on the bottom surface of the base plate 1 near the four sides. A screw 19 is connected to the inner surface of the threaded sleeve 18, and a washer 20 is provided at the bottom of the screw 19. By setting the threaded sleeve 18 and the screw 19, the height of the washer 20 can be adjusted when the screw 19 is rotated. When the washer 20 is in contact with the ground, the overall stability of the device can be improved. Universal wheels 21 are provided at the corners of the bottom surface of the base plate 1. The universal wheels 21 are fixed to the base plate 1 by screws. By setting the universal wheels 21, when the washer 20 is off the ground, the workers can move the entire device with the assistance of the universal wheels 21, which improves convenience. A fence 23 is installed near the edge of the upper surface of the construction platform 22. A telescopic ladder 24 is provided on the front surface of the construction platform 22. By setting the fence 23, the overall safety protection of the device can be improved. The telescopic ladder 24 makes it easy for workers to climb onto the surface of the construction platform 22.

[0025] During operation, the drive motor 13 drives the drive gear 14 to rotate, which in turn drives the driven gear 11 to rotate, thereby rotating the second transmission shaft 9 and achieving automatic adjustment of the entire device. The fixing bolts 15 improve the fixing strength between the motor base 12 and the base plate 1, preventing loosening. The positioning seat 16 and positioning rod 17 limit the lead screw 4, preventing the threaded tube 3 from rotating and causing the lead screw 4 to rotate, thus reducing transmission efficiency. The threaded sleeve 18 and screw 19 adjust the height of the shim 20 when the screw 19 is rotated, improving the overall stability of the device when the shim 20 is in contact with the ground. The casters 21 allow workers to move the entire device with the assistance of the casters 21 when the shim 20 is off the ground, improving convenience. The fence 23 improves the overall safety of the device. The telescopic ladder 24 facilitates workers to climb onto the surface of the construction platform 22.

[0026] Through the above steps, by setting the second bearing seat 8, the second transmission shaft 9 can rotate with the cooperation of the second bearing seat 8, thereby driving the two third bevel gears 10 to rotate. The third bevel gears 10 will drive the fourth bevel gear 25 meshing with them to rotate, thereby causing the first transmission shaft 6 to rotate with the cooperation of the first bearing seat 5. The first transmission shaft 6 can drive the second bevel gears 7 at both ends to rotate, thereby driving the first bevel gear 2 meshing with them to rotate, thereby driving the four threaded tubes 3 to rotate. When the threaded tubes 3 rotate, the screws 4 that are threaded with them can move up and down, thereby realizing the lifting and lowering of the construction platform 22. When adjusting the lifting platform, only the second transmission shaft 9 needs to be rotated, without the need to adjust multiple support rods, which simplifies the operation steps. This solves the problem that existing adjustable supports for building construction require the adjustment and positioning of multiple support rods separately when adjusting the height, which is cumbersome and not convenient for quick debugging.
