Description

Technical Field

[0001] This application relates to the technical field of construction equipment, and particularly relates to a fall prevention device for building components used in construction. Background Art

[0002] Construction refers to the production activities in the implementation stage of project construction and is the process of building various buildings. Building components refer to the various elements that make up a building and are the parts in building products, playing an indispensable and important role in construction and building. During the transportation of building components, fall prevention devices are often used to facilitate the transportation of building components to the locations where they are needed in the building.

[0003] When hoisting a building component onto a building, usually the building component is placed in a cage, and then the cage is hoisted onto the building. During the hoisting process, the cage provides a fall prevention effect for the building component. However, due to the different shapes and structures of building components, when placing a cylindrical or relatively small-sized building component in the cage, during the hoisting and transportation processes, the building component is likely to roll in the cage, causing the hoisted cage to tilt, posing a great safety hazard.

[0004] Regarding the above related technologies, the inventor found that during the hoisting and transportation processes, cylindrical building components are likely to roll in the cage, causing the hoisted cage to tilt, posing a great safety hazard. Summary of the Invention

[0005] In order to reduce the rolling of building components in the cage, this application provides a fall prevention device for building components used in construction.

[0006] A fall prevention device for building components used in construction provided by this application adopts the following technical solutions:

[0007] A fall prevention device for building components used in construction includes a cage. The cage includes a base and guard plates surrounding the base on all sides. A plurality of mounting plates are slidably arranged circumferentially and uniformly on the base. The mounting plates slide in a direction away from or towards the center of the base. Mounting rods are arranged on the mounting plates. First abutting plates for abutting against building components are arranged on the mounting rods. Second abutting plates are slidably arranged on the mounting rods. The sliding direction of the second abutting plates is along the length direction of the mounting rods. The two second abutting plates are respectively located on both sides of the first abutting plate. First adjusting components for adjusting the positions of the second abutting plates are arranged on the mounting rods. Second adjusting components for adjusting the positions of the mounting plates are arranged on the base.

[0008] By adopting the above technical solution, the position of the mounting plate is adjusted through the second adjusting component, so that the first abutting plate abuts against the building component placed in the middle of the base. The building component is tightly abutted from the circumferential direction by a plurality of first abutting plates, and the building component is fixed in the middle of the base. The position of the second abutting plate is adjusted through the first adjusting component, and the second abutting plate is abutted against the building component to further strengthen the stability of the building component and reduce the possibility of the building component slipping out from the gap between two adjacent first abutting plates. After the building component is fixed in the middle of the base, the possibility of the building component rolling or sliding in the cage during hoisting and transportation, causing the cage to tilt and deflect, is reduced, thereby reducing the possibility of the cage tipping over, improving the safety of hoisting and transportation, and being able to adaptively adjust the positions of the two second abutting plates according to the sizes and shapes of different building components, improving the applicability of the device.

[0009] Optionally, the first adjusting component includes a mounting block arranged on the mounting rod. Two adjusting rods are slidably arranged on the mounting block. The two adjusting rods are located on both sides of the mounting rod and are connected to the second abutting plate. A rack is arranged on one side of the adjusting rod close to the mounting rod. Two first gears are rotatably arranged on the mounting block. The two first gears are symmetrically arranged on both sides of the mounting rod. The two first gears are respectively meshed with the two racks. A second gear is slidably arranged on the mounting rod. The second gear is located between the two first gears. The second gear is respectively meshed with the two first gears. The distance between the central axes of the two first gears is less than the sum of the distances from the central axes of the two first gears to the central axis of the second gear respectively. An adjusting member for fixing the second gear is arranged on the mounting rod.

[0010] By adopting the above technical solution, when it is necessary to adjust the position of the second abutting plate, the second gear is slid to separate the second gear from the two first gears respectively, and the two adjusting rods are slid. The two adjusting rods drive the second abutting plate to move, so that the second abutting plate abuts tightly against the side wall of the building component, and the positions of the two second abutting plates can be adaptively adjusted according to the sizes and shapes of different building components. When the adjusting rod moves, it drives the rack to move, and the rack drives the first gear to rotate; after the second abutting plate abuts against the building component, the position of the second gear is adjusted to mesh the second gear with the two first gears respectively, and the second gear is fixed through the adjusting member. When the second abutting plate is stressed, it is necessary to push the rack to move, and the rack needs to drive the first gear to rotate. Because the rotation directions of the two first gears on both sides are opposite, and the two first gears are both meshed with the second gear, at this time, the second gear restricts the rotation of the two first gears, thereby restricting the backward movement of the second abutting plate.

[0011] Optionally, the adjusting member includes a central shaft, the second gear is sleeved on the central shaft, a sliding groove is formed on the fixing rod, a slider is slidably connected in the sliding groove, the slider is connected to the central shaft, the central shaft slidably penetrates through the fixing rod, a fixing groove is formed on the bottom wall of the sliding groove, the fixing rod penetrates through the slider and is inserted into the fixing groove, when the fixing rod is inserted into the fixing groove, the second gear meshes with the two first gears respectively, and an elastic part for driving the fixing rod to slide towards the fixing groove is arranged on the fixing rod.

[0012] By adopting the above technical solution, the elastic part drives the fixing rod to move towards the side close to the fixing groove. When the second gear moves to mesh with the first gear, the fixing rod moves to directly above the fixing groove. At this time, the fixing rod is inserted into the fixing groove under the action of the elastic member, fixing the second gear and restricting the movement of the second gear, so as to facilitate the fixing of the second abutting plate.

[0013] Optionally, the elastic part includes a spring sleeved on the fixing rod, a connecting block is arranged on the fixing rod, one end of the spring is connected to the connecting block, and the other end is connected to the central shaft, and the spring is in a stretched state.

[0014] By adopting the above technical solution, the spring is in a stretched state. When the fixing rod moves to directly above the fixing groove, the elastic force of the spring drives the fixing rod to be inserted into the fixing groove, thereby restricting the sliding of the second gear in the sliding groove, so as to facilitate the second gear to maintain the meshing state with the first gear.

[0015] Optionally, the mounting rod includes a mounting part and a connecting part, the connecting part is connected to the mounting plate, the first abutting plate is connected to the mounting part, the mounting block is located on the mounting part, the mounting part is rotatably connected to the connecting part, and a fixing member for fixing the mounting part is arranged on the connecting part.

[0016] By adopting the above technical solution, adjusting the fixing member can rotate the mounting part, and the mounting part drives the first abutting plate and the second abutting plate to rotate. When the cylindrical building component is placed upside down, adjusting the positions of the two second abutting plates after rotation can better fit and abut against the arc-shaped side wall of the cylindrical building component, so as to facilitate the fixing of building components in different placement methods. Therefore, the building component can be well fixed whether it is placed vertically or upside down, improving the practicability of the device.

[0017] Optionally, the fixing member includes a counter-boring bolt threadedly penetrating through the connecting part, and the counter-boring bolt abuts against the mounting part.

[0018] By adopting the above technical solution, adjusting the counter-boring bolt to be tightened against the mounting part can fix the mounting part on the connecting part, so as to facilitate the fixing after rotating the mounting part.

[0019] Optionally, the second abutting plate is hinged to the side of the adjusting rod away from the mounting plate, and the hinge axis of the second abutting plate is parallel to the rotation axis of the first gear.

[0020] By adopting the above technical solution, the second abutting plate is hinged to the adjusting rod. When the second abutting plate abuts against the building component, the second abutting plate is rotated to make the second abutting plate fit more closely with the side wall of the arc-shaped building component, thereby further improving the fixing effect on the building component and reducing the possibility of the building component moving.

[0021] Optionally, the second adjusting component includes a first lead screw rotatably arranged on the base. An adjusting block is threadedly connected to the first lead screw. An adjusting groove is formed in the base. The first lead screw is located in the adjusting groove. The mounting plate is connected to the adjusting block, and one end of the first lead screw extends outside the base.

[0022] By adopting the above technical solution, when the first lead screw is rotated, the first lead screw drives the adjusting block to move in the adjusting groove, and the adjusting block drives the mounting plate to move, thereby adjusting the position of the first abutting plate so that the first abutting plate abuts against the building component and fixes the building component on the base.

[0023] Optionally, a diagonal brace is arranged on the adjusting block. One end of the diagonal brace is connected to the adjusting block, and the other end is connected to the mounting plate.

[0024] By adopting the above technical solution, the diagonal brace plays a supporting role for the mounting plate, so as to improve the compressive resistance of the mounting plate and improve the supporting ability for the building component.

[0025] Optionally, buffer blocks are arranged around the bottom surface of the base.

[0026] By adopting the above technical solution, the arrangement of the buffer blocks is beneficial to buffering the cage when the hoisting cage is placed on the ground, so as to reduce the possibility that the impact during placement drives the building component to roll.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] Adjust the position of the mounting plate through the second adjustment component so that the first abutting plate abuts against the building component placed in the middle of the base. Press the building component tightly from the circumferential direction by multiple first abutting plates, and fix the building component in the middle of the base. Adjust the position of the second abutting plate through the first adjustment component, and abut the second abutting plate against the building component to further strengthen the stability of the building component, reduce the possibility of the building component slipping out from the gap between two adjacent first abutting plates. After fixing the building component in the middle of the base, it reduces the possibility of the building component rolling or sliding in the suspension cage during hoisting and transportation, resulting in the inclination and deflection of the suspension cage, thereby reducing the possibility of the suspension cage tipping over, improving the safety of hoisting and transportation, and being able to adaptively adjust the positions of the two second abutting plates according to the sizes and shapes of different building components, improving the applicability of the device.

One end of the diagonal brace 23 is welded to the regulating block 21, and the other end is welded and fixed to the mounting plate 3. The mounting plate 3, the regulating block 21 and the diagonal brace 23 form a triangle to improve the compressive capacity of the mounting plate 3. Buffer blocks 24 are fixedly adhered to the periphery of the bottom surface of the base 1. The buffer blocks 24 are rubber blocks, which play a buffering role for the suspension cage when the suspension cage is hoisted and placed on the ground, so as to reduce the possibility that the impact during placement drives the building component to roll.

[0039] Reference Figure 3 and Figure 4 As shown in FIGS. Figure 3 and Figure 4 , the mounting rod 4 includes a mounting portion 41 and a connecting portion 42. One end of the connecting portion 42 is fixedly welded to the sliding block 27, and the first abutting plate 5 is fixedly welded to one end of the mounting portion 41 away from the mounting plate 3. One end of the mounting portion 41 is rotatably connected to the inside of the connecting portion 42, and a fixing member for fixing the mounting portion 41 is provided on the connecting portion 42. The fixing member includes a counter-bolting screw 19 threadedly passing through the connecting portion 42, and the counter-bolting screw 19 passes through the connecting portion 42 and abuts against the mounting portion 41. By adjusting the counter-bolting screw 19, the mounting portion 41 is rotated by 90°. The mounting portion 41 drives the first abutting plate 5 and the second abutting plate 6 to rotate. When the cylindrical building component is placed upside down, the positions of the two rotated second abutting plates 6 are adjusted to fit and abut well against the arc-shaped side wall of the cylindrical building component, thereby improving the fixing effect of the building component.

[0040] Reference Figure 3 and Figure 4 As shown in FIGS. Figure 3 and Figure 4 , the first adjusting assembly includes a mounting block 7 fixedly welded to the mounting portion 41. The mounting portion 41 passes through the mounting block 7 and extends outside the mounting block 7. Two adjusting rods 8 are slidably connected to the mounting block 7. The sliding directions of the two adjusting rods 8 are parallel to the length direction of the mounting portion 41. The two adjusting rods 8 are located on both sides of the mounting rod 4 and are connected to the second abutting plate 6. The second abutting plate 6 is hinged to the side of the adjusting rod 8 away from the mounting plate 3, and the hinge axis of the second abutting plate 6 is parallel to the rotation axis of the first gear 10. A T-shaped block 28 is fixedly welded to the adjusting rod 8, and a T-shaped groove is formed in the mounting block 7. The T-shaped block 28 is adapted to the T-shaped groove, and the T-shaped block 28 is slidably connected in the T-shaped groove to limit the sliding direction of the adjusting rod 8. A rack 9 is integrally formed on the side of the adjusting rod 8 close to the mounting portion 41. Two first gears 10 are rotatably connected to the mounting block 7. The two first gears 10 are symmetrically arranged on both sides of the mounting portion 41. The two first gears 10 are respectively engaged with the two racks 9. A second gear 11 is slidably connected to the mounting rod 4. The second gear 11 is located between the two first gears 10. The second gear 11 is respectively engaged with the two first gears 10. The distance between the central axes of the two first gears 10 is less than the sum of the distances from the central axes of the two first gears 10 to the central axis of the second gear 11 respectively. The second gear 11 is located on the side close to the mounting plate 3, and an adjusting member for fixing the second gear 11 is provided on the mounting rod 4.

[0041] When it is necessary to adjust the position of the second abutting plate 6, slide the second gear 11 to separate the second gear 11 from the two first gears 10 respectively. Slide the two adjusting rods 8, and the two adjusting rods 8 drive the second abutting plate 6 to move, so that the second abutting plate 6 abuts tightly against the side wall of the building component, so as to adaptively adjust the positions of the two second abutting plates 6 according to the sizes and shapes of different building components. When the adjusting rod 8 moves, it drives the rack 9 to move, and the rack 9 drives the first gear 10 to rotate; after the second abutting plate 6 abuts against the building component, adjust the position of the second gear 11, mesh the second gear 11 with the two first gears 10 respectively, and then fix the position of the second gear 11; when the second abutting plate 6 is stressed, it is necessary to push the rack 9 to move, and the rack 9 needs to drive the first gear 10 to rotate. Because the rotation directions of the two first gears 10 on both sides are opposite, and the two first gears 10 are both meshed with the second gear 11, at this time, the second gear 11 restricts the rotation of the two first gears 10, thereby restricting the backward movement of the second abutting plate 6.

[0042] Refer to Figure 3 and Figure 4 , the adjusting member includes a central shaft 12. The second gear 11 is rotatably sleeved on the central shaft 12. A sliding groove 13 is formed in the fixing rod 15. A sliding block 14 is slidably connected in the sliding groove 13. The sliding block 14 is a T-shaped block, and the sliding groove 13 is a T-shaped groove adapted to the sliding block 14. A connecting groove 29 is formed in the mounting block 7. The connecting groove 29 communicates with the sliding groove 13. One end of the central shaft 12 passes through the connecting groove 29 and is connected to the sliding block 14. A fixing rod 15 is slidably inserted through the central shaft 12. The sliding direction of the fixing rod 15 is along the length direction of the central shaft 12. A fixing groove 16 is formed in the bottom wall of the sliding groove 13. The fixing rod 15 passes through the sliding block 14 and is inserted into the fixing groove 16. When the fixing rod 15 is inserted into the fixing groove 16, the second gear 11 is respectively meshed with the two first gears 10. An elastic part is arranged on the fixing rod 15 for driving the fixing rod 15 to slide towards the fixing groove 16. The elastic part includes a spring 17 sleeved on the fixing rod 15. A connecting block 18 is welded and fixed at the upper end of the fixing rod 15. One end of the spring 17 is welded and fixed on the connecting block 18, and the other end is welded and fixed on the central shaft 12. The spring 17 is in a stretched state.

[0043] When the fixing rod 15 moves to directly above the fixing groove 16, the elastic force of the spring 17 drives the fixing rod 15 to be inserted into the fixing groove 16, thereby restricting the sliding of the second gear 11 in the sliding groove 13, so as to facilitate the second gear 11 to maintain the meshed state with the first gear 10.

[0044] The implementation principle of an anti-falling device for building components used in building construction in an embodiment of this application is as follows: Rotate the first lead screw 20 to adjust the position of the mounting plate 3 so that the first abutting plate 5 abuts against the building component placed in the middle of the base 1. The three first abutting plates 5 abut against the building component circumferentially to clamp the building component tightly and fix the building component in the middle of the base 1. Adjust the position of the second abutting plate 6 to abut the second abutting plate 6 against the building component, further strengthening the stability of the building component and fixing the building component in the middle of the base 1. This reduces the possibility that the building component rolls or slides in the cage during hoisting and transportation, causing the cage to tilt and deflect, thereby reducing the possibility of the cage overturning and improving the safety of hoisting and transportation.

[0045] The above are all preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
