Description

Technical Field

[0001] The present application relates to the technical field of climbing frames, and in particular to a connection structure between a bottom scaffolding board and a closed flap. Background Art

[0002] Traditional scaffolding has a series of disadvantages and hidden dangers such as excessive material consumption during construction, too much high-altitude erection and dismantling operations, and excessive safety risks. The fully enclosed working system of the climbing frame greatly reduces the risks of high-altitude operations, and mechanized lifting reduces the intensity of operations, reflecting good safety and applicability.

[0003] At present, in order to facilitate the scaffolding to climb up and down along the building structure, a certain gap is left between the main structure of the scaffolding and the building structure. At the same time, when the lifting frame is suspended at a certain position of the building structure, the gap between the bottom scaffolding board and the main body of the building structure is covered with a closed flap to ensure safety in use. Specifically, one end of the closed flap is hinged to the bottom scaffolding board, and the other end of the closed flap after folding is abutted against the building structure, thereby covering the gap between the scaffolding and the building structure.

[0004] In the prior art, in order to improve the coverage of the gap, the width of the closed flap is usually greater than the distance between the bottom scaffolding board and the building structure. When the bottom scaffolding board and the floor board in the building structure are not at the same horizontal position, the closed flap is tilted. If the tilt angle is large, when the workers are working in the scaffolding, the tilted closed flap is difficult to become the workers' working space, so that there is a certain distance between the workers' standing position and the building structure, which increases the difficulty of the workers' operation, so further improvement is needed. Utility Model Content

[0005] In order to increase the operating space for the staff and reduce the operating difficulty for the staff, the present application provides a connection structure between a bottom scaffolding board and a closed flap.

[0006] The present application provides a connection structure between a bottom scaffolding board and a closed flap, which adopts the following technical solution:

[0007] A connection structure between a bottom scaffolding board and a closed flap, comprising an inner cantilever board arranged between the bottom scaffolding board and the closed flap, a first mounting piece for detachably connecting the inner cantilever board to the bottom scaffolding board, and a second mounting piece for rotatably connecting the closed flap to the inner cantilever board; the inner cantilever board comprises a horizontal board arranged parallel to the bottom scaffolding board and a vertical board arranged perpendicular to the horizontal board, the lower surface of the horizontal board abuts against the upper surface of the bottom scaffolding board, the horizontal board protrudes from the bottom scaffolding board, the vertical board is detachably connected to the side wall of the bottom scaffolding board close to the building structure through the first mounting piece, and the closed flap is rotatably connected to the upper surface of the horizontal board away from the bottom scaffolding board; a pulling rope for pulling the closed flap to flip along the second mounting piece is arranged on the bottom scaffolding board, the lower end of the pulling rope is fixedly connected to one end of the closed flap close to the building structure, and the bottom scaffolding board is provided with a pulling component for pulling the upper end of the pulling rope.

[0008] By adopting the above technical solution, an inner cantilever board is provided, and the horizontal operating space of the staff is extended to one side of the building structure through the transverse board in the inner cantilever board, so that the position where the staff can stand is closer to the building structure, thereby facilitating the staff to operate the outside of the building structure and improving the work efficiency of the staff. Among them, since one end of the transverse board abuts against the upper surface of the bottom scaffolding board, the vertical board is installed on the bottom scaffolding board through the first mounting member to improve the bearing effect of the inner cantilever board when under pressure, and since the transverse board is provided, the closed flap is further away from the scaffolding board, and it is more difficult to close the closed flap, so the pulling assembly is used to pull the pulling rope so as to pull the closed flap to close it.

[0009] Preferably, the opposite side walls of the bottom scaffolding board are respectively provided with an inner pole and an outer pole, and the pulling assembly includes a mounting rod fixedly connected to the inner pole for the pulling rope to be wound around, and a fixing member arranged on the mounting rod for limiting the rotation of the pulling rope.

[0010] By adopting the above technical solution, when the closed flap needs to be unfolded, the pull rope is unlocked through the fixing member so that the pull rope is separated from the installation rod, and a thrust is applied to the closed flap to unfold the closed flap. When a pulling force is applied to the pull rope, the closed flap is driven to rotate along the rotation point between the pull rope and the horizontal board, so that the closed flap rotates toward the direction close to the horizontal board. When it rotates to a suitable position, the pull rope is wound around the installation rod and fixed by the fixing member to reduce the possibility of the closed flap shaking when the bottom scaffolding board is raised or lowered.

[0011] Preferably, the fixing member comprises an elastic clamping ring fixedly connected to the upper end of the pulling rope and a clamping ring fixedly connected to the free end of the mounting rod, and the clamping ring is provided with a clamping groove for the elastic clamping ring to be engaged.

[0012] By adopting the above technical solution, an elastic clamp is fixedly connected to the free end of the pulling rope, so that the elastic clamp can be stretched appropriately. In the process of winding the pulling rope around the mounting rod, when the elastic clamp is wound to the point where it is embedded in the slot and needs to be stretched to be embedded in the slot, the pulling rope is wound. At this time, the elastic clamp in a stretched state is embedded in the slot and is fixed by the elastic force of the elastic clamp itself.

[0013] Preferably, a pulling portion is protruding from the elastic clamping ring.

[0014] By adopting the above technical solution, after the elastic clamping ring is applied with force by pinching the pulling portion, the elastic clamping ring embedded in the clamping groove can be disengaged from the clamping groove, thereby reducing the time spent on unfolding the closed flap.

[0015] Preferably, an anti-slip sleeve is provided on the outer peripheral wall of the mounting rod.

[0016] By adopting the above technical solution and providing an anti-slip sleeve, the friction between the pull rope and the mounting rod can be increased to reduce the possibility of the pull rope slipping and detaching from the mounting rod when winding it around the mounting rod, thereby affecting the winding effect of the pull rope.

[0017] Preferably, the pulling rope is a steel wire rope.

[0018] By adopting the above technical solution, the pulling rope is set as a steel wire rope, which can reduce the possibility of the pulling rope being broken by external forces, and can provide certain support when the closed flap is in a horizontally arranged state and under pressure.

[0019] Preferably, a support rod is fixedly connected to the lower surface of the closed flap, and a slot for the support rod to be slidably inserted is provided on the lower end surface of the horizontal plate.

[0020] By adopting the above technical solution, a support rod is provided to provide a certain support for the closed flap when some closed flaps and the horizontal plate are in a parallel setting state, so as to further improve the bearing effect when the closed flap is under pressure when it abuts against the building structure and is horizontally set.

[0021] Preferably, the transverse plate comprises a first transverse plate vertically fixed to the vertical plate and a second transverse plate rotatably connected to the first transverse plate, and the closed flap is rotatably connected to the second transverse plate via a second mounting member.

[0022] By adopting the above technical solution, in this embodiment, by providing a second horizontal plate rotatably connected to the first horizontal plate, the pulling rope can be continuously pulled while applying force to the pulling rope to drive the closed flap to close, so as to drive the flipping of the second horizontal bar, so as to increase the gap between the scaffolding and the building structure, so as to reduce the possibility of the horizontal plate colliding with the building structure when the bottom scaffolding is raised or lowered.

[0023] Preferably, the side walls of the vertical plate are fixedly connected with reinforcing ribs, a plurality of the reinforcing ribs are arranged at intervals along the length direction of the vertical plate, and the lower end surface of the second horizontal plate abuts against the reinforcing ribs.

[0024] By adopting the above technical solution, since the original horizontal plate includes a first horizontal plate and a second horizontal plate, and since the second horizontal plate is rotatable, it may affect the bearing effect of the second horizontal plate to a certain extent, so reinforcing ribs are provided to provide support for the second horizontal plate.

[0025] In summary, the utility model has the following beneficial effects:

[0026] 1. The horizontal operating space for the staff is extended to one side of the building structure through the horizontal plate in the inner cantilever plate, so that the staff can stand closer to the building structure, which is convenient for the staff to operate on the outside of the building structure and improve the work efficiency of the staff.

[0027] 2. Since the horizontal board is provided to make the closed flap further away from the scaffolding board, it is relatively difficult to close the closed flap. Therefore, the pulling rope is pulled by pulling the assembly to pull the closed flap to close it. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-9 , further details of this application are given.

[0039] The embodiment of the present application discloses a connection structure between a bottom scaffolding board and a closed flap.

[0040] Embodiment 1:

[0041] A connection structure between the bottom scaffolding board and the closed flap, referring to Figure 1 , Figure 2 , including an inner cantilever board 3 arranged between the bottom scaffolding board 1 and the closed flap 2, a first mounting member 4 for detachably connecting the inner cantilever board 3 to the bottom scaffolding board 1, and a second mounting member 5 for rotatably connecting the closed flap 2 to the inner cantilever board 3.

[0042] The bottom scaffolding board 1 is arranged at the bottom of the scaffolding to ensure the stability of the spacing between the scaffolding and the wall, to avoid displacement affecting the overall stability of the scaffolding and to improve safety. For the bottom scaffolding board 1, angle steels 11 are fixedly connected around the bottom scaffolding board 1, and adjacent angle steels 11 are fixedly connected by welding. The angle steels 11 located in the length direction of the bottom scaffolding board 1 are penetrated with circular holes 111, and the circular holes 111 are arranged at intervals along the length direction of the angle steels 11.

[0043] Reference Figure 2 , Figure 3 For the connection between adjacent bottom scaffolding boards 1, connecting plates 12 are provided on the opposite sides of the two bottom scaffolding boards 1. After the connecting plates 12 are abutted against the angle steel 11, a first bolt 13 is passed through the connecting plate 12. After the first bolt 13 is passed through the circular hole 111, a first nut 14 is threadedly connected to connect the adjacent bottom scaffolding boards 1. Several first bolts 13 are arranged at intervals along the length direction of the connecting plate 12, and specifically four are arranged.

[0044] It should be noted that the opposite side walls of the bottom scaffolding board 1 are respectively provided with an inner upright 15 and an outer upright 16, which are both passed through the circular hole 111 by the first bolt 13 and then threadedly connected with the first nut 14 to install the inner upright 15 and the outer upright 16 on the bottom scaffolding board 1, and the inner upright 15 and the outer upright 16 are arranged to avoid the inner cantilever board 3.

[0045] Reference Figure 2 , Figure 4 , wherein the inner cantilever board 3 includes a horizontal board 32 arranged parallel to the bottom scaffolding board 1 and a vertical board 31 arranged perpendicular to the horizontal board 32. In this embodiment, the lower surface of the horizontal board 32 abuts against the upper surface of the bottom scaffolding board 1, and the horizontal board 32 protrudes from the bottom scaffolding board 1. The vertical board 31 abuts against the side wall of the angle steel 11 and is detachably connected to the side wall of the bottom scaffolding board 1 close to the building structure through the first mounting member 4. In this embodiment, the first mounting member 4 includes a second bolt 41 penetrating through the vertical board 31 and the circular hole 111 and a second nut 42 threadedly connected to the second bolt 41, so as to install the vertical board 31 on the bottom scaffolding board 1.

[0046] Among them, the closed flap 2 is rotatably connected to the upper surface of the horizontal board 32 away from the bottom scaffolding board 1. In this embodiment, the second mounting member 5 is specifically a hinge to realize the rotatable connection of the closed flap 2. Since the hinge is a prior art, it will not be described in detail here.

[0047] Reference Figure 1 , Figure 4 Furthermore, due to the provision of the horizontal plate 32, the closed flap 2 is further away from the scaffolding board, making it more difficult to close the closed flap 2. In this embodiment, a pulling rope 6 is provided on the bottom scaffolding board 1 for pulling the closed flap 2 to flip along the rotation direction of the hinge. The pulling rope 6 is a steel wire rope, and the lower end of the pulling rope 6 is fixedly connected to one end of the closed flap 2 close to the building structure.

[0048] Reference Figure 5 The bottom scaffolding board 1 is provided with a pulling assembly 7 for pulling the upper end of the pulling rope 6. The pulling assembly 7 specifically includes a mounting rod 71 fixedly connected to the inner upright 15 for winding the pulling rope 6 and a fixing member 72 provided on the mounting rod 71 for limiting the rotation of the pulling rope 6. The fixing member 72 includes an elastic clamping ring 721 fixedly connected to the upper end of the pulling rope 6 and a clamping ring 722 fixedly connected to the free end of the mounting rod 71. The clamping ring 722 is provided with a clamping groove 8 for the elastic clamping ring 721 to be clamped.

[0049] Furthermore, in order to facilitate the separation of the elastic clamping ring 721 embedded in the clamping slot 8 from the clamping slot 8, in this embodiment, the elastic clamping ring 721 is made of elastic silicone, and a pulling portion 9 is protruding from the elastic clamping ring 721. The pulling portion 9 can be a pulling piece made of the same material as the elastic clamping ring 721, or can be made of other silicone, plastic or wooden board with a smaller elastic coefficient. It is set according to needs. In this embodiment, silicone with a smaller elastic coefficient is selected so that the pulling portion can be pinched to separate the elastic clamping ring 721 from the clamping slot 8.

[0050] Furthermore, an anti-slip cover 711 is provided on the outer peripheral wall of the mounting rod 71, and the anti-slip cover 711 is supported by silica gel, so as to increase the friction between the anti-slip cover 711 and the pulling rope 6, and reduce the possibility of the pulling rope 6 slipping during the pulling process. It can provide a large friction force to the steel wire rope, and provide a certain support when the closed flap 2 is in a horizontal state and under pressure.

[0051] The implementation principle of the connection structure between the bottom scaffolding board and the closed flap according to the embodiment of the present application is as follows: when the closed flap 2 needs to be unfolded, the pulling part 9 is pulled to disengage the elastic snap ring 721 from the slot 8, and then the pull rope 6 is disengaged from the mounting rod 71, and a thrust is applied to the closed flap 2 to unfold the closed flap 2, and then the excess pull rope 6 is wound around the mounting rod 71, and the elastic snap ring 721 is clamped in the slot 8 to fix the length of the pull rope 6. When the closed flap 2 needs to be closed, the elastic snap ring 721 is first disengaged from the slot 8, and then the pull rope 6 is pulled to drive the closed flap 2 to flip, and then the pull rope 6 is wound around the mounting rod 71, and the elastic snap ring 721 is clamped in the slot 8 to fix the pull rope 6 at this time, so as to reduce the possibility of the closed flap 2 rotating due to external force.

[0052] Embodiment 2:

[0053] Reference Figure 6 , Figure 7 , which is different from the first embodiment, is that, during use, when the bottom scaffolding board 1 is raised and lowered to be parallel to the floor or to leave a height difference, the closed flap 2 and the horizontal board 32 may be in a parallel setting state. In particular, for the height difference, when stepping on the closed flap 2, the connection between the closed flap 2 and the horizontal board 32, i.e., the hinge, may be subjected to excessive force and may break.

[0054] Therefore, in this embodiment, the lower surface of the closed flap 2 is fixedly connected with a support rod 21, and the length direction of the support rod 21 is inclined to the surface of the closed flap 2, specifically inclined toward the horizontal plate 32. The support rod 21 is fixedly connected to the middle part of the closed flap 2 to reduce the possibility of collision between the support rod 21 and the building structure, wherein the lower end surface of the horizontal plate 32 is provided with a slot 321 for the support rod 21 to slide and insert. The support rod 21 is provided to provide a certain support to the closed flap 2, reduce the possibility of hinge rupture, and further improve the bearing effect when the closed flap 2 is pressed against the building structure and is horizontally arranged.

[0055] Embodiment 3:

[0056] Reference Figure 8 , Fig. 9 , which is different from the first embodiment, is that the horizontal plate 32 includes a first horizontal plate 322 vertically fixed to the vertical plate 31 and a second horizontal plate 323 rotatably connected to the first horizontal plate 322, wherein the second horizontal plate 323 is also installed with the first horizontal plate 322 via a hinge. At this time, the second mounting member 5 is installed between the closed flap 2 and the second horizontal plate 323, so that the closed flap 2 is rotatably connected to the second horizontal plate 323.

[0057] Since the original horizontal plate 32 includes the first horizontal plate 322 and the second horizontal plate 323, and the second horizontal plate 323 is rotatable, the bearing effect of the second horizontal plate 323 may be affected to a certain extent. Therefore, in this embodiment, the side wall of the vertical plate 31 is fixedly connected with a reinforcing rib 10, and a plurality of reinforcing ribs 10 are arranged at intervals along the length direction of the vertical plate 31. The lower end surface of the second horizontal plate 323 abuts against the reinforcing rib 10 to provide support for the second horizontal plate 323.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
