Description

A fall prevention device for scaffolding Technical Field

[0001] The present invention relates to the technical field of lifting scaffold auxiliary equipment, in particular to a scaffold anti-falling device. Background Art

[0002] The lifting scaffolding is a high-efficiency scaffolding derived from the hanging basket climbing frame. It consists of a horizontal truss and a multi-layer scaffolding arranged on the horizontal truss. The lifting scaffolding can be linked with the bracket attached to the building wall to achieve up and down movement.

[0003] The main function of the hanger is to provide a fulcrum for the climbing of the scaffolding, and at the same time to ensure the stability and safety of the scaffolding. Therefore, the hanger itself also has an anti-falling function. In the prior art, the anti-falling device on the hanger generally adopts a blocking structure, which uses the fact that the blocking block cannot rebound in time during rapid falling to achieve the blocking connection between the hanger and the slide rail to achieve the purpose of anti-falling. However, the existing blocking structure usually needs to rely on the overspeed drive of the hanger and the slide rail in a single direction. That is to say, when the slide rail moves downward rapidly relative to the hanger, the anti-falling function can be triggered, but when the slide rail moves upward rapidly relative to the hanger, the corresponding locking function cannot be achieved. For some scaffoldings that use counterweights as auxiliary drives, if the drive end fails, the counterweight may cause the scaffold to hit the top, causing danger.

[0004] In view of this, how to provide a fall prevention device for scaffolding that can prevent falling and top impact at the same time has become one of the technical problems that need to be solved urgently.

[0005] Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of the present invention belong.

[0033] As shown in FIG1 , in combination with FIG2-6 , the anti-fall device for scaffolding of the present invention comprises: a wall-mounted base 1, a top rod 2 and a guide device 3. The wall-mounted base 1 comprises a vertically arranged fixing plate, clamping plates arranged parallel to the fixing plate at opposite ends in the horizontal direction, and a support plate arranged horizontally on the side of the fixing plate away from the wall. A through groove and / or through hole is provided on the surface of the fixing plate. The fixing plate can be fixed to the vertical wall through the corresponding through groove and / or through hole structure. The top rod 2 is rotatably mounted on the upper surface of the support plate. A guide device 3 is provided on the opposite side of the clamping plates on both sides. The guide device 3 is used to slide with the lifting guide rail on the scaffold. A driving device 4 and a hinged device are also provided between the two clamping plates. The rod 5 and the two brake blocks 6 are arranged at intervals in the vertical direction. The two brake blocks 6 rotate around a fixed axis respectively. The fixed axis is horizontally connected between the two clamping plates. The fixed axis is parallel to the fixed plate. The two brake blocks 6 are hinged at one end close to the fixed plate through the hinged rod 5. The driving device 4 is arranged between the two clamping plates and is connected to the guide rail transmission. When the guide rail slides relative to the wall mount 1 exceeding the safe speed, the driving device 4 can selectively drive the hinged rod 5 to reciprocate in the vertical direction under the driving action of the guide rail. Specifically, the driving device 4 can drive the hinged rod 5 to move in the direction of movement of the guide rail, and drive the brake block 6 close to the side of the guide rail moving direction to rotate until it abuts against the guide rail for braking.

[0034] In the above embodiment, two brake blocks 6 are provided, which are hingedly connected by an articulated rod 5 to form a linkage structure. When the articulated rod 5 moves upward, the upper brake block 6 rotates and moves away from one end of the fixed plate into the braking zone of the guide rail. At the same time, the lower brake block 6 rotates and moves away from the guide rail. When the articulated rod 5 moves downward, the lower brake block 6 rotates and moves away from one end of the fixed plate into the braking zone of the guide rail. At the same time, the upper brake block 6 rotates and moves away from the guide rail. When the articulated rod 5 is in the middle position, the brake blocks 6 at both ends cannot brake. In the above embodiment, parallel and spaced cross bars are provided along the vertical direction on the side of the guide rail near the wall mount 1. The cross bars are used to cooperate with the top rod 2 and the brake blocks 6 to support and brake the lifting scaffold. During braking, the brake blocks 6 abut against the surface of the cross bars.

[0035] In some embodiments, the driving device 4 includes a rotating shaft 41, a rotary damper 42, an elastic member 43 and a shift block 44. The rotating shaft 41 is horizontally rotated and arranged between two clamping plates. The axis of the rotating shaft 41 is parallel to the fixed plate. The rotary dampers 42 are coaxially arranged at both ends of the rotating shaft 41. The rotary damper 42 is an infinite angle type rotary damper 42. The rotating part of the rotating shaft 41 and the rotary damper 42 are coaxially keyed. The shift block 44 is fixedly connected to the fixed parts of the two rotary dampers 42. At the same time, the shift block 44 is elastically connected to the support plate through the elastic member 43. The rotating shaft 41 is transmission-connected to the guide rail surface, and the shift block 44 is transmission-connected to the hinged rod 5. When the guide rail is displaced relative to the wall mount 1 at a normal speed, the rotation speed of the rotating shaft 41 is low, and the fixed end of the rotary damper 42 is insufficient to generate sufficient torque to drive the shift block 44 to deform the elastic member 43. At this time, the shift block 44 remains stable, and the two brake blocks 6 cannot rotate to achieve the braking purpose; when the guide rail slides beyond the normal speed, the rotation speed of the rotating shaft 41 is high, and the fixed end of the rotary damper 42 generates a greater torque. At this time, the shift block 44 overcomes the elastic force of the elastic member 43 and deforms it under the drive of the torque of the damper 42. At this time, the shift block 44 rotates and drives the articulated rod 5 to displace, and the two brake blocks 6 rotate as the articulated rod 5 moves and achieves the corresponding braking purpose.

[0036] Different from conventional anti-falling devices, the two brake blocks 6 used in the anti-falling structure can selectively resist and block in different directions according to the rapid sliding of the guide rail in different directions, thereby achieving both anti-falling and anti-top impact.

[0037] In some embodiments, it also includes a driving wheel 45, a driven wheel 46 and a transmission belt 47. The driving wheel 45 is rotatably set on the wall mount 1, and the driven wheel 46 is coaxially keyed to the rotating shaft 41. The driving wheel 45 and the driven wheel 46 are transmitted through the transmission belt 47, and the driving wheel 45 is rollingly connected to the guide rail surface.

[0038] In the above embodiment, as one of the feasible exemplary structures of the transmission connection between the guide rail and the rotating shaft 41, a driving wheel 45 and a driven wheel 46 are used for transmission. Specifically, the rotation axis of the driving wheel 45 is parallel to the rotating shaft 41, and the driving wheel 45 is arranged to be rolled on the surface of the guide rail. During the rolling process of the driving wheel 45, the driven wheel 46 is driven to rotate by the transmission belt 47, and the rotation of the driven wheel 46 drives the conversion path 41 to rotate. In the above exemplary embodiment, the rotation direction of the driving wheel 45 is the same as the rotation direction of the driven wheel 46. Therefore, when the guide rail falls downward rapidly, after being driven by the driving wheel 45, the transmission belt 47 and the driven wheel 46, as shown in Figure 6, the lower brake block 6 extends out and brakes the guide rail, otherwise, the upper brake block extends out and brakes the guide rail.

[0039] In some embodiments, the transmission belt 47 may be a chain structure, and the corresponding driving wheel 45 and driven wheel 46 may be gears.

[0040] In some embodiments, gears may be used as a transmission structure to transmit power between the guide rail and the rotating shaft 41 . Depending on the transmission system, the rotation direction of the corresponding shift block 44 may be opposite to the rotation direction of the driving wheel.

[0041] In some embodiments, an adjustment block 7 is further included, and the driving wheel 45 is rotatably set on the adjustment block 7. The surface of the clamping plate on the wall mount 1 is provided with an adjustment groove 11 in a direction perpendicular to the plane where the fixed plate is located, and the adjustment block 7 can be adjustably installed in the adjustment groove 11.

[0042] In the above embodiment, an adjustment block 7 is provided to adjust the rolling contact between the driving wheel 45 and the guide rail to maintain close contact between the driving wheel 45 and the guide rail. Specifically, the adjustment slot 11 is used to limit and guide the adjustment block 7, and the adjustment block 7 can ultimately be fastened to the wall mount 1 via bolts.

[0043] In some embodiments, a slider 441 is protruding from the surface of the shift block 44 , and a guide groove 51 is provided on the surface of the hinge rod 5 along a direction perpendicular to the length of the hinge rod 5 , and the slider 441 is slidably set in the guide groove 51 .

[0044] The specific working structure of the above embodiment can be referred to Figures 3, 5 and 6. The length direction of the guide groove 51 in the above embodiment is perpendicular to the length direction of the hinge rod 5, and can be approximately perpendicular. In order to avoid the slider 441 receiving direction being perpendicular to the inner wall of the guide groove 51 under the action of the rotational torque of the shift block 44, the guide groove 41 can be set to be not perpendicular to the direction of the rotational force arm of the slider 441.

[0045] In some embodiments, the elastic member 43 includes two tension springs 431, which are elastically connected to the two side surfaces of the shift block 44 along the vertical direction of the guide rail. The ends of the two tension springs 431 away from the shift block 44 are connected to the surface of the wall mount 1. The elastic extension direction of the two tension springs 431 is parallel to the extension direction of the guide rail. When the shift block 44 is not driven by the rotary damper 42 and the two tension springs 431 are in a force balance state, the two brake blocks 6 are not in braking contact with the guide rail.

[0046] In the above embodiment, the shift block 44 includes a rotating portion and a lever portion protruding from the rotating portion. The rotating portion is coaxially arranged with the rotating shaft 41. The lever portion is used to transmit power to the hinged rod 5. To prevent the lever portion from swinging downward under the action of its own weight, two tension springs 431 are provided to maintain the lever portion at a horizontal or nearly horizontal position when in a stable state. At this time, when the lever portion is in a linked state with the hinged rod 5, as shown in Figure 3, both brake blocks 6 are unable to make braking contact with the guide rail. To provide a connection point for the tension spring 431 at the lower end, a second support plate is provided below the lower brake block 6. The second support plate is used to connect to the tension spring 431 located below.

[0047] It should be understood that the two tension springs 431 are deformed by the rotation of the shift block 44, and the torque required for the deformation is provided by the rotary damper 42. Therefore, the selection of the rotary damper 42 should be based on the following: when the corresponding brake block 6 can reach the braking position, the resultant force of the torque of the two tension springs 431 and the deadweight of the force arm is the same as the torque of the fixed end of the rotary damper 42 at the safety speed limit.

[0048] In some embodiments, a limiting through groove 61 is formed on a surface of the brake block 6 close to one end of the guide rail along the extending direction of the guide rail.

[0049] In the above embodiment, when the brake block 6 is driven to abut against the guide rail and brake, if the brake block 6 and the guide rail cannot be locked, the shift block 44 may continue to recover to a balanced state under the drive of the elastic member 43. At this time, the brake block 6 is separated from the guide rail and the guide rail may overspeed again. Therefore, a through groove 61 is provided to cooperate with the cross bar on the guide rail to achieve the locking purpose and prevent the brake block 6 from resetting.

[0050] In some embodiments, the guide device 3 includes at least two groups of guide wheels 31, each group of guide wheels 31 includes two guide wheels 31 respectively arranged on the two side surfaces of the wall-mounted base 1 along the direction perpendicular to the extension direction of the guide rail, and multiple groups of guide wheels 31 are arranged at intervals on the surface of the wall-mounted base 1 along the extension direction of the guide rail.

[0051] In the above embodiment, at least two guide wheels 31 are arranged in a vertical array on one side of the two clamping plates and close to one end of the fixed plate. The guide wheels 31 and the guide rail are used to limit the position and enable the guide rail to slide relative to the wall mount 1.

[0052] In some embodiments, the top rod 2 includes a rotating rod 21 and an extension rod 22. The end of the rotating rod 21 close to the wall mounting base 1 is rotatably hinged to the wall mounting base 1, and the end of the rotating rod 21 away from the wall mounting base 1 is adjustably connected to the extension rod 22. The extension rod 22 can move back and forth relative to the rotating rod 21 along its axial direction. The end of the extension rod 22 away from the rotating rod 21 is provided with a card-connecting groove.

[0053] In the above embodiment, the top rod 2 is used to support the lifting scaffolding. The rotating rod 21 is provided to make the top rod 2 swing as a whole, thereby choosing to support the scaffolding or allowing the scaffolding to move up and down. The extension rod 22 is provided to make the overall length of the top rod 2 adjustable. According to different support scenarios, top rods 2 of different lengths can be selected. The card-connected slot structure usually matches the support positioning structure of the lifting scaffolding.

[0054] In some embodiments, the extension rod 22 is threadedly connected to the rotating rod 21 .

[0055] In the above embodiment, the extension length of the extension rod 22 can be changed by rotating the extension rod 22 , thereby changing the length of the overall push rod 2 .

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
