Description

Technical Field

[0001] This invention relates to the field of scaffolding technology, and more specifically, to an anti-tipping device for mobile work platforms in underground civil defense projects and its application method. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It is classified according to its location as external scaffolding and internal scaffolding; according to materials as wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; and according to its structural form as pole-type scaffolding, bridge-type scaffolding, frame-type scaffolding, suspended scaffolding, hanging scaffolding, cantilevered scaffolding, and climbing scaffolding. In practice, scaffolding is prone to tipping over, affecting safety and construction efficiency. Therefore, installing anti-tipping devices in scaffolding is a necessary and common safety measure in the industry.

[0003] A search revealed a patent application with application number 202020487240X that discloses an anti-tipping device for mobile scaffolding. The device includes a fixed rod and a support rod, with the fixed rod connected to the uprights of the mobile scaffolding. The fixed rod and the support rod are connected by an upper connecting rod and a lower connecting rod. This application increases the support area at the bottom of the mobile scaffolding, thereby increasing its stability and preventing it from tipping over. However, an unavoidable problem in use is that the device is fixed to the bottom of the scaffolding. When the scaffolding needs to be raised, the stress point remains unchanged, and the stress on the anti-tipping device increases. When the maximum stress point is reached, the anti-tipping device will be damaged. Summary of the Invention

[0006] 2. Technical Solution

[0007] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0008] The present invention relates to an anti-tipping device for a mobile working platform in underground civil defense engineering, comprising a scaffold, wherein a sliding column is connected to one side of the scaffold via a horizontal column, the sliding column extending along the height direction of the scaffold, and a moving mechanism is provided on the outer wall of the scaffold; the moving mechanism includes a sliding box slidably fitted onto the scaffold, a sleeve provided on one side of the sliding box, the sleeve being slidably fitted onto the sliding column; the sliding box is also provided with a locking unit for locking the sliding box onto the scaffold.

[0009] Furthermore, the locking unit includes bolts, and the sliding box and the wall of the scaffold are respectively provided with mating mounting holes. The bolts pass through the outer wall of the sliding box and are threaded inward to the wall of the scaffold.

[0010] Furthermore, the locking unit also includes a connecting block located at the front end of the bolt. The outer end of the connecting block is provided with a bevel gear, and the outer side of the slide box is also provided with a crossbar. The connecting column rotates through the crossbar. One end of the connecting column is provided with a handle, and the other end of the connecting column is provided with a bevel gear set for engaging with the bevel gear at the end of the connecting block for transmission. The bolt is rotated by the handle.

[0011] Furthermore, the moving mechanism includes at least two sets of sliding boxes mounted on the scaffold, with multiple sets of sliding boxes distributed vertically and each set having bolts, and a linkage component between the multiple sets of bolts.

[0012] Furthermore, the linkage component includes a toothed belt, with connecting blocks at the ends of multiple sets of bolts, and toothed pulleys are fitted on the outer sides of the connecting blocks, with the multiple sets of toothed pulleys connected by a toothed belt for transmission.

[0013] Furthermore, the inner side of the slide box is provided with an L-shaped rod, the end of the horizontal extension of the L-shaped rod is connected to the sleeve, and the two sides of the extension of the L-shaped rod are also connected by diagonal rods to form a triangular frame.

[0014] Furthermore, the scaffolding is equipped with multiple sets of sliding boxes, the inner sides of which are fixedly connected to L-shaped rods.

[0015] Furthermore, the diagonal brace is also equipped with a horizontally extending connecting rod that connects to the sleeve.

[0016] Furthermore, the inner cavity of the sliding box is also equipped with a slider, and the wall surface of the scaffold is provided with a corresponding sliding groove along the height direction to cooperate with the slider.

[0017] The application method of the anti-tipping device for the mobile working platform of the underground civil defense project of the present invention is carried out according to the following process: when the scaffolding needs to be lengthened, the locking unit is controlled to release the sliding box from the scaffolding, and the sliding box and sleeve are moved to corresponding positions on the scaffolding and the sliding column respectively. When the sliding box is moved to a suitable height position, the locking unit is controlled to relock the sliding box to the scaffolding.

[0018] 3. Beneficial effects

[0031] The present invention will be further described below with reference to embodiments.

[0032] Example 1

[0033] Combination Figure 1 The anti-tipping device for the mobile working platform of the underground civil defense project in this embodiment includes a scaffold 1. A sliding column 4 is connected to one side of the scaffold 1 through a horizontal column 3. The sliding column 4 extends along the height direction of the scaffold 1. A moving mechanism 6 is provided on the outer wall of the scaffold 1. The moving mechanism 6 includes a sliding box 608 that is slidably fitted on the scaffold 1. A sleeve 5 is provided on one side of the sliding box 608. The sleeve 5 is slidably fitted on the sliding column 4. A locking unit is also provided on the sliding box 608 for locking the sliding box 608 on the scaffold 1.

[0034] Specifically, the bottom of scaffold 1 is equipped with casters 2, and the bottom end of scaffold 1 is equipped with horizontal columns 3 connected to sliding columns 4, with the sliding columns 4 extending vertically. For example... Figure 4 As shown, the locking unit includes a bolt 607, a sliding box 608, and mating mounting holes on the wall of the scaffold 1. The bolt 607 passes through the mating mounting hole on the outer wall of the sliding box 608 and is threadedly connected to the threaded mounting hole on the wall of the scaffold 1 for locking.

[0035] In this embodiment, a sliding box 608 and a sleeve 5 are respectively slidably engaged with the scaffold 1 and the sliding column 4. The movement of the sliding box 608 synchronously drives the movement of the sleeve 5. A locking unit allows control of the locking or loosening state between the sliding box 608 and the scaffold 1. When the scaffold 1 needs to be lengthened, the locking unit is controlled to release the sliding box 608 from the scaffold 1, and the sliding box 608 and sleeve 5 are moved to corresponding positions on the scaffold 1 and the sliding column 4, respectively. When the appropriate height is reached, the locking unit is controlled to relock the sliding box 608 to the scaffold 1. This allows for flexible adjustment of the positions of the sliding box 608 and sleeve 5 as needed, thereby meeting the requirements for controlling changes in the support force points. Compared with traditional fixed-point structures, this effectively avoids damage to the anti-tipping device, significantly extends its service life, and improves safety.

[0036] Example 2

[0037] The anti-tipping device for the mobile work platform in the underground civil defense project in this embodiment is basically the same as in Embodiment 1, but more specifically, as follows: Figure 3 As shown, the locking unit also includes a connecting block 604 located at the front end of the bolt 607. The outer end of the connecting block 604 is provided with a bevel gear, and the outer side of the slide box 608 is also provided with a crossbar 7. The connecting column 602 rotates through the crossbar 7. One end of the connecting column 602 is provided with a handle 601, and the other end of the connecting column 602 is provided with a bevel gear set 603 for engaging with the bevel gear at the end of the connecting block 604 for transmission. The bolt 607 is driven to rotate through the handle 601.

[0038] In this embodiment, the inner side of the slide box 608 specifically refers to the side closer to the sleeve 5, while the outer side refers to the side away from the sleeve 5. A crossbar 7 is provided at the bottom outer side of the slide box 608. The connecting column 602 is installed on the outer end of the crossbar 7 through a rotating bearing. The bottom end of the connecting column 602 is provided as a handle 601, and the top end of the connecting column 602 is provided as a bevel gear set 603. The bevel gear set 603 meshes with the bevel gear at the outer end of the connecting block 604, so that the rotation direction and degree of the bolt 607 can be controlled by manually operating the handle 601, realizing flexible switching between the locked and loosened states.

[0039] Example 3

[0040] The anti-tipping device for the mobile work platform in the underground civil defense project of this embodiment is basically the same as the above embodiment. More specifically, the mobile mechanism 6 includes at least two sets of sliding boxes 608 mounted on the scaffold 1. The multiple sets of sliding boxes 608 are distributed vertically and are respectively provided with bolts 607. A linkage component is provided between the multiple sets of bolts 607. The linkage component includes a toothed belt 606. The ends of the multiple sets of bolts 607 are respectively provided with connecting blocks 604, and toothed pulleys 605 are fitted on the outer side of each connecting block 604. The multiple sets of toothed pulleys 605 are driven by the toothed belt 606.

[0041] Specifically, such as Figure 1 and Figure 2 As shown, this embodiment includes two sets of sliding boxes 608 arranged vertically. The two sets of sliding boxes 608 are connected by a toothed pulley 605 and a toothed belt 606. Thus, the locking or loosening state of both sets of sliding boxes 608 can be controlled simultaneously by the handle 601. Correspondingly, the inner sides of the two sets of sliding boxes 608 are connected to the sleeve 5, achieving a more stable support structure.

[0042] Example 4

[0043] The anti-tipping device for the mobile work platform in the underground civil defense project in this embodiment is basically the same as the above embodiment. More specifically, the inner side of the sliding box 608 is provided with an L-shaped rod 10. The end of the horizontal extension of the L-shaped rod 10 is connected to the sleeve 5, and the two sides of the extension of the L-shaped rod 10 are also connected by diagonal rods 9 to form a triangular frame. Specifically, multiple sets of sliding boxes 608 are provided on the scaffold 1. The inner side of the multiple sets of sliding boxes 608 is fixedly connected to the L-shaped rod 10, and the diagonal rod 9 is also provided with a horizontally extending connecting rod 8 connected to the sleeve 5.

[0044] refer to Figure 1 As shown, the scaffold 1 is equipped with two sets of sliding boxes 608. The inner sides of the two sets of sliding boxes 608 are connected to the two ends of the vertical extension of the L-shaped rod 10, respectively. The horizontal extension of the L-shaped rod 10 extends to connect with the bottom end of the sleeve 5. The diagonal rod 9 connects the horizontal and vertical extensions of the L-shaped rod 10, forming a triangular frame structure. The lower part of the diagonal rod 9 is connected to the top of the sleeve 5 through the connecting rod 8. The connecting rod 8, the diagonal rod 9, and the sleeve 5 also form a triangular frame structure. This design can effectively enhance the overall structural strength and stability, avoid damage under stress, and improve safety in use.

[0045] Example 5

[0046] The anti-tipping device for the mobile work platform in the underground civil defense project in this embodiment is basically the same as the above embodiment. More specifically, refer to... Figure 5 The inner cavity of the sliding box 608 is also equipped with a slider 6a1, and the wall surface of the scaffold 1 is provided with a corresponding groove 6a2 along the height direction to cooperate with the slider 6a1. By utilizing the guiding cooperation of the slider 6a1 and the groove 6a2, the sliding of the sliding box 608 is ensured to be smoother when the position moves, and intermittent sliding is prevented.

[0047] In summary, the anti-tipping device for the mobile working platform in underground civil defense engineering of the present invention operates as follows in practical application: At a construction site, when the scaffold 1 needs to be lengthened, the locking unit is controlled to release the sliding box 608 from the scaffold 1, i.e., the handle 601 is rotated. The handle 601 drives the connecting column 602 to rotate, which in turn drives the bevel gear set 603 to rotate, thereby driving the lower connecting block 604 to rotate. The lower connecting block 604 drives the toothed pulley 605 to rotate, which in turn drives the toothed belt 606 to rotate, and further drives the upper toothed pulley 605 to rotate. Driven by 05, the upper toothed pulley 605 drives the upper connecting block 604 to rotate. The two connecting blocks 604 drive the bolts 607 to rotate, and the two bolts 607 leave the threaded holes of the scaffold 1. Stop rotating the handle 601, and the worker pushes the two sliding boxes 608 to slide in the scaffold 1. The two sliding boxes 608 drive the L-shaped rod 10 to move, and the L-shaped rod 10 drives the sleeve 5 to slide in the sliding column 4. When it moves to the appropriate position, turn the handle 601 in the opposite direction, and the two bolts 607 rotate into the threaded holes to achieve locking. When raising the scaffold 1, repeat the above steps.

[0048] The present invention and its embodiments have been described above illustratively. This description is not restrictive and is merely one embodiment of the present invention, and is not actually limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
