Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, specifically relating to an installation and positioning mechanism for prefabricated buildings. Background Technology

[0002] Prefabricated construction is an industrialized construction method. Its core is to transfer a large amount of on-site work (such as concrete pouring and component processing) in traditional construction to factories. Prefabricated components include floor slabs, wall panels, stairs and balconies, which are then transported to the site and assembled into a whole building by means of bolting, welding or adhesive. Prefabricated construction requires the use of installation and positioning mechanisms during the construction process.

[0003] Existing installation positioning mechanisms use a load-bearing mechanism to support and position the steel structure to be assembled. However, since the load-bearing mechanism cannot be moved, the steel structure needs to be manually dragged during the subsequent assembly process until one side of the two steel structures is tightly fitted before the installation work can continue. Because the steel structure is heavy, dragging it is extremely time-consuming and laborious, reducing the efficiency of the installation. Therefore, we provide an installation positioning mechanism for prefabricated buildings. Utility Model Content

[0004] The purpose of this utility model is to provide an installation and positioning mechanism for prefabricated buildings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an installation and positioning mechanism for prefabricated buildings, comprising a base, a motor fixedly installed on the left side of the base, a lead screw fixedly connected to the output end of the motor, threaded sleeves threadedly connected to both sides of the lead screw surface, a connecting column fixedly connected to the top of the threaded sleeve, a bearing plate fixedly connected to the top of the connecting column, a sleeve column fixedly connected to the top of the bearing plate, a movable plate movably connected to the inner cavity of the sleeve column, a sleeve rod fixedly connected to the top of the movable plate, a load-bearing plate fixedly connected to the top of the sleeve rod, a concave frame fixedly connected to the load-bearing plate, an electric push rod fixedly connected to the top of the concave frame, and a pressure plate fixedly connected to the top of the electric push rod.

[0006] Using the above scheme, the motor drives the lead screw to rotate. Because the lead screw has two opposite threads on its surface, the lead screw drives two threaded sleeves to move inward. The threaded sleeves, in cooperation with the connecting column, drive the bearing plate to move. The bearing plate, in cooperation with the sleeve column, drives the movable plate and sleeve rod to move. The sleeve rod drives the load-bearing plate to move. The load-bearing plate drives the steel structure to move until one side of the two steel structures is tightly fitted together and the movement stops. There is no need for manual dragging of the steel structure, which saves time and effort and greatly improves construction efficiency.

[0007] In a preferred embodiment of an installation positioning mechanism for prefabricated buildings, a set of positioning holes are provided on the sleeve rod, and the positioning holes are fixedly connected to the sleeve column by positioning bolts.

[0008] Using the above method, when it is necessary to adjust the height of the load-bearing plate, simply unscrew the positioning bolt from the connection between the positioning hole and the sleeve column to release the limit on the sleeve rod, and pull the load-bearing plate upward to adjust the working height of the load-bearing plate. After the adjustment is completed, screw the positioning bolt back into the positioning hole.

[0009] In a preferred embodiment of an installation and positioning mechanism for prefabricated buildings, sliding grooves are provided on both sides of the inner cavity of the sleeve column, and sliders are fixedly connected to both sides of the movable plate, with the surface of the sliders slidably connected to the inner wall of the sliding groove.

[0010] By adopting the above scheme, the sliding groove is set to assist the movable plate in moving with the cooperation of the slider, and the moving distance of the movable plate is limited to prevent the movable plate from detaching from the inner cavity of the sleeve column.

[0011] In a preferred embodiment of an installation and positioning mechanism for prefabricated buildings, one end of the lead screw is movably connected to a bearing, and one side of the bearing is fixedly connected to one side of the inner cavity of the base.

[0012] By adopting the above solution, the bearing is used to limit one end of the lead screw, preventing one end of the lead screw from being suspended in the air and thus causing vibration.

[0013] In a preferred embodiment of an installation and positioning mechanism for prefabricated buildings, a power supply box is fixedly connected to the back of the base, and the inner cavity of the power supply box is equipped with a storage battery.

[0014] By adopting the above solution, the electrical equipment is powered by a storage battery to maintain its normal operation.

[0015] In a preferred embodiment of an installation and positioning mechanism for prefabricated buildings, a guide groove is provided at the bottom of the inner cavity of the base, a guide block is fixedly connected to the bottom of the threaded sleeve, and the bottom of the guide block is slidably connected to the inner wall of the guide groove.

[0016] By adopting the above scheme, the guide block is limited by the setting of the guide groove, which assists the threaded sleeve in moving and improves the smoothness of the threaded sleeve movement.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a motor to drive a lead screw to rotate. Because the surface of the lead screw has two opposite threads, the lead screw drives two threaded sleeves to move inward. With the cooperation of the connecting column, the threaded sleeves drive the bearing plate to move. With the cooperation of the sleeve column, the bearing plate drives the movable plate and sleeve rod to move. The sleeve rod drives the load-bearing plate to move. The load-bearing plate drives the steel structure to move until one side of the two steel structures is tightly attached and the movement stops. There is no need for manual dragging of the steel structure, which saves time and effort and greatly improves construction efficiency.

[0019] 2. This utility model uses an electric push rod to move the pressure plate downward until the bottom of the pressure plate is tightly fitted with the top of the steel structure and then the movement stops. By changing the distance between the pressure plate and the sleeve rod, steel structures of different sizes can be pressed down and fixed. Attached Figure Description

[0024] Please see Figure 1-3 An installation and positioning mechanism for prefabricated buildings includes a base 1, a motor 2 fixedly mounted on the left side of the base 1, and a lead screw 3 fixedly connected to the output end of the motor 2. Figure 2 As shown, a bearing is movably connected to one end of the lead screw 3, and one side of the bearing is fixedly connected to one side of the inner cavity of the base 1. The bearing limits one end of the lead screw 3 to prevent it from being suspended and thus vibrating. Threaded sleeves 4 are threaded to both sides of the surface of the lead screw 3. A connecting post 5 is fixedly connected to the top of the threaded sleeve 4. A bearing plate 6 is fixedly connected to the top of the connecting post 5. A sleeve post 7 is fixedly connected to the top of the bearing plate 6. A movable plate 8 is movably connected to the inner cavity of the sleeve post 7. A sleeve rod 9 is fixedly connected to the top of the movable plate 8. See Figure 2 and Figure 3As shown, a set of positioning holes 11 are provided on the sleeve rod 9. The positioning holes 11 are fixedly connected to the sleeve post 7 by positioning bolts 12. When it is necessary to adjust the height of the load-bearing plate 10, simply unscrew the positioning bolts 12 from the connection between the positioning holes 11 and the sleeve post 7 to release the limitation on the sleeve rod 9, and pull the load-bearing plate 10 upward to adjust the working height of the load-bearing plate 10. After the adjustment is completed, screw the positioning bolts 12 back into the positioning holes 11. The top of the sleeve rod 9 is fixedly connected to the load-bearing plate 10, and a concave frame 13 is fixedly connected to the load-bearing plate 10. An electric push rod 14 is fixedly connected to the top of the concave frame 13. A pressure plate 15 is fixedly connected to the top of the push rod 14. The motor 2 drives the lead screw 3 to rotate. Since the surface of the lead screw 3 has two opposite threads, the lead screw 3 drives the two threaded sleeves 4 to move inward. The threaded sleeves 4, with the cooperation of the connecting column 5, drive the bearing plate 6 to move. The bearing plate 6, with the cooperation of the sleeve column 7, drives the movable plate 8 and the sleeve rod 9 to move. The sleeve rod 9 drives the load-bearing plate 10 to move. The load-bearing plate 10 drives the steel structure to move until one side of the two steel structures is tightly attached and the movement stops. There is no need for manual dragging of the steel structure, which saves time and effort and greatly improves the efficiency of construction.

[0025] See Figure 3 As shown, sliding grooves are provided on both sides of the inner cavity of the sleeve column 7, and sliders are fixedly connected to both sides of the movable plate 8. The surfaces of the sliders are slidably connected to the inner walls of the sliding grooves. Through the setting of the sliding grooves, the movable plate 8 is assisted in moving with the cooperation of the sliders, and the moving distance of the movable plate 8 is limited to prevent the movable plate 8 from detaching from the inner cavity of the sleeve column 7. A power supply box is fixedly connected to the back of the base 1, and a battery is installed in the inner cavity of the power supply box. Through the setting of the battery, power is supplied to the electrical equipment to maintain the normal operation of the electrical equipment. See Figure 2 As shown, a guide groove is provided at the bottom of the inner cavity of the base 1, and a guide block is fixedly connected to the bottom of the threaded sleeve 4. The bottom of the guide block is slidably connected to the inner wall of the guide groove. By setting the guide groove, the guide block is limited, which helps the threaded sleeve 4 to move and improves the smoothness of the movement of the threaded sleeve 4.

[0026] In use, first place one end of the steel structure inside the load-bearing plate 10. After placement, start the electric push rod 14, which drives the pressure plate 15 downward until the bottom of the pressure plate 15 is tightly fitted with the top of the steel structure, at which point the movement stops. By changing the distance between the pressure plate 15 and the sleeve rod 9, steel structures of different sizes can be pressed down and fixed. Then, start the motor 2, which converts electrical energy into mechanical energy and drives the lead screw 3 to rotate. Because the surface of the lead screw 3 has two opposite threads, when the lead screw 3 is rotating, it can drive the two threaded sleeves 4 to move inward. With the cooperation of the connecting column 5, the threaded sleeves 4 drive the bearing plate 6 to move, thus supporting the load. With the cooperation of the sleeve column 7, plate 6 drives the movable plate 8 and sleeve rod 9 to move. The sleeve rod 9 drives the load-bearing plate 10 to move, and the load-bearing plate 10 drives the steel structure to move until one side of the two steel structures is tightly attached and the movement stops. Then the subsequent installation work can be carried out. There is no need for manual dragging of the steel structure, which saves time and effort and greatly improves the construction efficiency. Finally, when it is necessary to adjust the height of the load-bearing plate 10, simply unscrew the positioning bolt 12 from the connection between the positioning hole 11 and the sleeve column 7 to release the restriction on the sleeve rod 9, and pull the load-bearing plate 10 upward to adjust the working height of the load-bearing plate 10. After the adjustment is completed, screw the positioning bolt 12 back into the positioning hole 11.
