DETAILED DESCRIPTION

[0035] See also Figures 1 to 8 As shown, an embodiment of the present application provides an attachment support structure of a scaffold, including a support device 2, the support device 2 includes: a wall-attached support 21, an anti-overturning component 22, a top support component 23 and an anti-falling component 24, the wall-attached support 21 is fixedly connected to the building on one side close to the building, the anti-overturning component 22 is clamped in the track groove of the guide rail 1, the anti-overturning component 22 is fixedly connected to the wall-attached support 21 on the side away from the building, a top support component 23 is arranged on the wall-attached support 21, the top of the top support component 23 is clamped with the anti-falling cross piece of the guide rail 1, the anti-falling component 24 is rotatably arranged at the bottom of the wall-attached support 21, the anti-falling component 24 is clamped with the anti-falling cross piece of the guide rail 1, each guide rail 1 is provided with at least three wall-attached supports 21 along its vertical direction, and each wall-attached support 21 is provided with an anti-falling component 24.

[0036] In the above scheme, the wall-mounted support 21 is fixed on the building by the anti-overturning component 22, and the wall-mounted support 21 and the anti-falling crossbar of the guide rail 1 are tightened by the arranged top support component 23. When the scaffolding suddenly falls, the guide rail 1 slides down with the scaffolding as a whole. At this time, the anti-falling crossbar of the guide rail 1 will touch the anti-falling component 24, and the anti-falling component 24 rotates clockwise. The anti-falling component 24 is clamped between the anti-falling crossbars of the guide rail 1, which can effectively jam the scaffolding, has a fast reaction speed, has an anti-falling effect on the scaffolding, and improves the safety of the scaffolding.

[0037] In some possible implementations, see Figures 5 to 8 As shown, the anti-falling assembly 24 includes a load-bearing shaft 242 rotatably arranged on the wall-mounted support 21, an anti-falling pendulum block 241 is fixedly sleeved on the load-bearing shaft 242, a slot is provided on the side of the anti-falling pendulum block 241 close to the guide rail 1, a trigger block 244 is arranged in the slot, the trigger block 244 is rotatably sleeved on the load-bearing shaft 242, a long shaft 246 is arranged in the slot, a trigger block torsion spring 245 is movably sleeved on the long shaft 246, and the trigger block torsion spring 245 is used when the trigger block 244 is not in contact with the anti-falling crosspiece of the guide rail 1. During a collision, the trigger block 244 and the guide rail 1 are perpendicular to each other, and two ends of the trigger block torsion spring 245 respectively abut against the trigger block 244 and the anti-falling pendulum block 241, and the trigger block 244 is detachably connected to the anti-falling crossbar of the guide rail 1, and pendulum block tension springs 243 are provided on both sides of the anti-falling pendulum block 241. The pendulum block tension spring 243 is used to reset the anti-falling pendulum block 241, and one end of the pendulum block tension spring 243 is away from the anti-falling pendulum block 241 and is connected to the wall-mounted support 21, and the two ends of the anti-falling pendulum block 241 are detachably connected to the wall-mounted support 21 and the guide rail 1 respectively.

[0038] In some possible embodiments, referring to Figure 7 As shown in connection with Figure 8 the anti-falling pendulum block 241 has a first clamping end 2411 and a second clamping end 2412. The first clamping end 2411 is detachably connected to the anti-falling crossbar of the guide rail 1, and the second clamping end 2412 is detachably connected to the wall-attached support 21. A protrusion 2413 is provided on one side of the first clamping end 2411 close to the wall-attached support 21, and the protrusion 2413 is detachably connected to the anti-falling crossbar of the guide rail 1; the trigger block 244 has a short baffle 2442 and an extension tongue 2441. The extension tongue 2441 is detachably connected to the anti-falling crossbar of the guide rail 1, and the short baffle 2442 is detachably connected to the second clamping end 2412. When the first clamping end 2411 is clamped between the anti-falling crossbars of the guide rail 1, the protrusion 2413 abuts against the anti-falling crossbar of the guide rail 1, so that the clamping effect between the first clamping end 2411 and the anti-falling crossbar of the guide rail 1 is better.

[0039] It should be noted that during the upward movement of the scaffolding, the trigger block 244 is always in contact with the anti-falling crossbar of the guide rail 1, and the anti-falling pendulum block 241 and the trigger block 244 are not stressed. When the scaffolding suddenly drops, the anti-falling crossbar of the guide rail 1 touches the extension tongue 2441 of the trigger block 244, causing the trigger block 244 to rotate clockwise. The trigger block 244 rotates clockwise to drive the anti-falling pendulum block 241 to rotate clockwise through the short baffle 2442, so that the first clamping end 2411 of the anti-falling pendulum block 241 is clamped between the anti-falling crossbars of the guide rail 1. At the same time, the second clamping end 2412 of the anti-falling pendulum block 241 is clamped at the bottom of the wall-attached support 21, thereby supporting the scaffolding and achieving an anti-falling effect. When the scaffolding is caught by the anti-falling component 24 after suddenly dropping, if it needs to be reset, the scaffolding needs to be started to make the scaffolding rise. When the scaffolding rises, the first clamping end 2411 is subjected to an upward thrust from the anti-falling crossbar of the guide rail 1, and at the same time, it rotates counterclockwise under the action of the tension of the pendulum spring 243, and at the same time drives the trigger block 244 to rotate counterclockwise until the anti-falling pendulum block 241 is parallel to the guide rail 1.

[0040] When the scaffolding is in a static state, the anti-falling pendulum block 241 is parallel to the guide rail 1, and the trigger block 244 is always perpendicular and intersecting with the anti-falling crossbar of the guide rail 1; during the descent of the scaffolding, the trigger block 244 mainly plays a role. Since during the descent, the anti-falling crossbar of the guide rail 1 will touch the trigger block 244, which causes the anti-falling pendulum block 241 to rotate. When the scaffolding descends at a constant speed, the anti-falling crossbar of the guide rail 1 touches the extension tongue 2441, so that the short baffle 2442 drives the anti-falling pendulum block 241 to rotate clockwise by a certain small angle, making the first clamping end 2411 of the anti-falling pendulum block 241 not get stuck between the anti-falling crossbars of the guide rail 1, and always swing slightly along the load-bearing shaft 242. Once the scaffolding suddenly drops, the force on the trigger block 244 from the anti-falling crossbar of the guide rail 1 increases, causing the short baffle 2442 to suddenly push the anti-falling pendulum block 241 to rotate clockwise, so that the first clamping end 2411 of the anti-falling pendulum block 241 quickly gets stuck between the anti-falling crossbars of the guide rail 1, thus playing an anti-falling role.

[0041] In some possible implementation schemes, as shown in Figure 4 The anti-overturning assembly 22 includes a fixing plate 221. The wall-attached support 21 is fixed to the guide rail 1 through the fixing plate 221. At least two movable guide wheels 222 are arranged on the fixing plate 221 through a guide wheel shaft. The guide wheels 222 are movably arranged in the guide rail groove of the guide rail 1. When the scaffolding is lifted or lowered, the guide wheels 222 arranged in the guide rail groove of the guide rail 1 are clamped with the guide rail groove to prevent the scaffolding from tilting outwards. The specification of the guide wheel shaft is φ26*55mm, the outer diameter of the guide wheel 222 is φ62mm, the inner hole diameter size is φ27mm, and the distance between the two guide wheels 222 is 90mm.

[0042] In some possible implementation schemes, as shown in Figure 1 and Figure 2 The wall-attached support 21 is fixedly connected to the building through wall-piercing bolts 3 on the side close to the building. The size of the wall-piercing bolts 3 is M36*600mm, and the distance between the two wall-piercing bolts 3 is 200mm.

[0043] In some possible implementation schemes, as shown in Figure 3 The top support assembly 23 includes a top support seat 231. The top support seat 231 is movably arranged on the wall-attached support 21 through a pin shaft 235. A threaded adjustment screw rod 232 is arranged on the top support seat 231. Both ends of the adjustment screw rod 232 are provided with threads, and the thread directions are opposite. A threaded top support head 234 is arranged at one end of the adjustment screw rod 232 away from the top support seat 231.

[0044] In the above solution, after the wall-attached support 21 is fixed, by rotating the adjusting screw rod 232, the length between the top support seat 231 and the top support head 234 is increased. When the top support head 234 can be clamped between the anti-falling crossbars of the guide rail 1, continue to rotate the adjusting screw rod 232 to make the clamping between the top support head 234 and the anti-falling crossbars of the guide rail 1 firm, so that the top support assembly 23 further supports the guide rail 1 and improves the stability of the support.

[0045] In some possible implementation solutions, as shown in Figure 3 As shown, a fixed nut 233 is sleeved on the adjusting screw rod 232. When rotating the adjusting screw rod 232, the adjusting screw rod 232 can be rotated by the cooperation of a wrench and the nut 233.

[0046] The wall-attached support 21 is fixedly arranged on the building through the anti-overturning assembly 22, and the wall-attached support 21 is tightly pressed against the anti-falling crossbars of the guide rail 1 through the arranged top support assembly 23. When the scaffolding suddenly falls, the guide rail 1 slides down integrally with the scaffolding. At this time, the anti-falling crossbars of the guide rail 1 will touch the anti-falling assembly 24, and the anti-falling assembly 24 rotates clockwise. The anti-falling assembly 24 is clamped between the anti-falling crossbars of the guide rail 1, which can effectively lock the scaffolding, has a fast response speed, plays an anti-falling role for the scaffolding, and improves the safety of using the scaffolding.

[0047] This specific embodiment is only an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions according to needs, but as long as they are within the protection scope of the utility model, they are protected by the patent law.
