Description

Technical Field

[0001] The utility model relates to the technical field of scaffold anti-falling equipment, in particular to an anti-falling device for an attached lifting scaffold. Background Art

[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. According to the location of the scaffolding, it can be divided into external scaffolding and internal scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; according to the structural form, it can be divided into vertical pole scaffolding, bridge scaffolding, door scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding.

[0003] At present, most scaffolds are mainly protected from falling by anti-falling cross bars on the guide rails during use. However, when the user stands on the scaffold to use it, the anti-falling cross bars used on the scaffold may cause falling accidents due to errors in spacing processing. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is to provide an anti-falling device for an attached lifting scaffold, which can prevent the guide rail and the scaffold from falling when the guide rail falls, in view of the current status of the prior art.

[0006] (II) Technical solution

[0007] The utility model is achieved through the following technical scheme: the utility model proposes an anti-falling device for an attached lifting scaffold, comprising an anti-falling pendulum block, anti-falling pendulum block fixing pin shaft holes are symmetrically opened in the middle of both side walls of the anti-falling pendulum block, anti-falling pendulum block fixing pin shafts are installed in the anti-falling pendulum block fixing pin shaft holes, a trigger mounting groove is opened on the lower side of the anti-falling pendulum block, a trigger is installed in the trigger mounting groove through the trigger fixing pin shaft, a trigger fixing pin shaft hole is opened on the anti-falling pendulum block at the trigger fixing pin shaft, a connecting platform is also installed on the anti-falling pendulum block at the upper side of the trigger mounting groove, and a trigger reset spring is installed between the connecting platform and the trigger.

[0008] Furthermore, the anti-falling pendulum block has an overall streamlined structure, and the fixing pin of the anti-falling pendulum block is plugged into the fixing pin hole of the anti-falling pendulum block.

[0009] By adopting the above technical solution, the anti-falling pendulum block adopts a streamlined structural design to disperse stress, thereby improving the anti-deformation ability of the anti-falling pendulum block when subjected to force.

[0010] Furthermore, a boss is installed on the anti-falling pendulum block at the outside of the fixing pin shaft hole of the anti-falling pendulum block, and the boss is formed on the anti-falling pendulum block.

[0011] By adopting the above technical solution, the friction resistance of the surface contact of the anti-fall pendulum block during installation can be reduced with the help of the boss.

[0012] Furthermore, one end of the trigger reset spring is connected to the trigger hook, and the other end of the trigger reset spring is connected to the connecting platform hook.

[0013] By adopting the above technical solution, the trigger reset spring is mainly used to realize automatic reset of the trigger when the limit is released after being triggered.

[0014] Furthermore, the trigger fixing pin is plugged into the trigger fixing pin hole, and the trigger fixing pin is rotatably connected to the trigger.

[0015] By adopting the above technical solution, the trigger can be ensured to be easily triggered and rotated when in use under the action of the trigger fixing pin.

[0016] Furthermore, a guide rail is arranged on one side of the anti-falling pendulum block, and anti-falling cross bars are installed on the guide rail at equal intervals from top to bottom, and a stopper is arranged on the side of the anti-falling pendulum block opposite to the guide rail.

[0017] By adopting the above technical solution, when the guide rail falls down, the anti-fall cross bar on the guide rail touches the end of the trigger away from the anti-fall pendulum block, so that the anti-fall pendulum block can rotate clockwise around the anti-fall pendulum block fixing pin shaft and be inserted between the upper and lower anti-fall cross bars. As the guide rail continues to fall downward, the tail of the anti-fall pendulum block fits against the stop block so that the anti-fall pendulum block no longer rotates clockwise.

[0018] Furthermore, the trigger is inserted into the gap between two adjacent anti-falling cross bars, and a gap is reserved between the anti-falling pendulum block and the guide rail.

[0019] By adopting the above technical solution, it can be ensured that the trigger can be easily rotated when the anti-fall cross bar falls.

[0020] Furthermore, the stopper is fixed on a scaffold, and the fixing pin of the anti-falling pendulum block is rotatably connected to the scaffold.

[0021] By adopting the above technical solution, the stopper can interfere with and limit the trigger after the trigger rotates.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] In order to solve the problem that most scaffolds currently use the anti-fall cross bars on the guide rails for anti-fall protection during use, but when the user stands on the scaffold to use it, the anti-fall cross bars used on the scaffold may cause falling accidents due to errors in spacing processing, the utility model installs an anti-fall pendulum block between the anti-fall cross bar on the guide rail and the stopper on the scaffold, so that when the guide rail falls and descends, the anti-fall cross bar on the guide rail touches the end of the trigger away from the anti-fall pendulum block, so that the anti-fall pendulum block can rotate clockwise around the anti-fall pendulum block fixing pin as the center, and is inserted between the upper and lower anti-fall cross bars. As the guide rail continues to fall downward, the tail of the anti-fall pendulum block fits the stopper so that the anti-fall pendulum block no longer rotates clockwise, and at the same time, the end of the anti-fall pendulum block away from the trigger is engaged between the two anti-fall cross bars, so that the anti-fall cross bar is restricted by the anti-fall pendulum block and stops and no longer falls, thereby achieving the anti-fall effect.

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] like Figure 1-Figure 4 As shown, an anti-falling device for an attached lifting scaffold in this embodiment includes an anti-falling pendulum block 1, which has a streamlined structure as a whole. The streamlined structure design of the anti-falling pendulum block 1 can disperse stress and improve the anti-deformation ability of the anti-falling pendulum block 1 when subjected to force. Anti-falling pendulum block fixing pin shaft holes 5 are symmetrically opened in the middle of the two side walls of the anti-falling pendulum block 1, and an anti-falling pendulum block fixing pin shaft 9 is installed in the anti-falling pendulum block fixing pin shaft hole 5. A trigger mounting groove 7 is opened on the lower side of the anti-falling pendulum block 1, and a trigger mounting groove 7 is installed in the trigger mounting groove 7 through the trigger fixing pin shaft 3. A trigger fixing pin shaft hole 8 is opened on the anti-fall pendulum block 1 at the trigger fixing pin shaft 3, and a connecting platform 13 is installed on the anti-fall pendulum block 1 at the upper side of the trigger mounting groove 7, and a trigger reset spring 4 is installed between the connecting platform 13 and the trigger 2. The trigger reset spring 4 is mainly used to realize the automatic reset of the trigger 2 when the limit is released after being triggered. The anti-fall device is designed as a modular structure as a whole, so that it is convenient for the staff to take the stored parts during disassembly and installation, and at the same time, it can prevent the parts from being missed and falling when the reusable device is transferred.

[0033] like Figure 1-Figure 4 As shown, in the present embodiment, the fixing pin shaft 9 of the anti-falling pendulum block is plugged into the fixing pin shaft hole 5 of the anti-falling pendulum block, and a boss 6 is further installed on the anti-falling pendulum block 1 at the outside of the fixing pin shaft hole 5 of the anti-falling pendulum block, and the boss 6 is formed on the anti-falling pendulum block 1. With the help of the boss 6, the friction resistance of the surface contact of the anti-falling pendulum block 1 during installation can be reduced, one end of the trigger reset spring 4 is hooked and connected with the trigger 2, and the other end of the trigger reset spring 4 is hooked and connected with the connecting platform 13, the trigger fixing pin shaft 3 is plugged into the trigger fixing pin shaft hole 8, and the trigger fixing pin shaft 3 is rotatably connected with the trigger 2. Under the action of the trigger fixing pin shaft 3, the convenient triggering and rotation of the trigger 2 during use can be ensured.

[0034] like Figure 3 and Figure 4 As shown, in the present embodiment, a guide rail 10 is also arranged on one side of the anti-falling pendulum block 1, and anti-falling cross bars 11 are installed on the guide rail 10 at equal intervals from top to bottom, and a stopper 12 is arranged on the side of the anti-falling pendulum block 1 opposite to the guide rail 10. When the guide rail 10 falls down, the anti-falling cross bar 11 on the guide rail 10 touches the end of the trigger 2 away from the anti-falling pendulum block 1, so that the anti-falling pendulum block 1 can rotate clockwise around the anti-falling pendulum block fixing pin 9 as the center, and be inserted between the upper and lower anti-falling cross bars 11. As the guide rail 10 continues to fall downward, the tail of the anti-falling pendulum block 1 fits against the stopper 12 so that the anti-falling pendulum block 1 no longer rotates clockwise.

[0035] like Figure 3 and Figure 4As shown, in this embodiment, the trigger 2 is inserted into the gap between two adjacent anti-falling cross bars 11, and a gap is reserved between the anti-falling pendulum block 1 and the guide rail 10, which can ensure the convenient rotation of the trigger 2 when the anti-falling cross bar 11 falls. The block 12 is fixed on the scaffolding, and the anti-falling pendulum block fixing pin 9 is rotatably connected to the scaffolding. The block 12 can interfere with and limit the trigger 2 after the trigger 2 rotates.

[0036] The specific implementation process of this embodiment is as follows: when in use, the anti-fall pendulum block 1 is fixed by the anti-fall pendulum block fixing pin 9, and a gap is maintained between the anti-fall pendulum block 1 and the guide rail 10. When the guide rail 10 falls down, the anti-fall cross bar 11 on the guide rail 10 touches the end of the trigger 2 away from the anti-fall pendulum block 1, so that the anti-fall pendulum block 1 can rotate clockwise around the anti-fall pendulum block fixing pin 9 and be inserted between the upper and lower anti-fall cross bars 11. As the guide rail 10 continues to fall downward, the tail of the anti-fall pendulum block 1 fits against the stop block 12 so that the anti-fall pendulum block 1 no longer rotates clockwise. At the same time, the end of the anti-fall pendulum block 1 away from the trigger 2 is engaged between the two anti-fall cross bars 11, so that the anti-fall cross bar 11 is restricted by the anti-fall pendulum block 1 and stops falling, thereby achieving an anti-fall effect.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
