Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lifting scaffolds, in particular to an anti-falling guide rail of the lifting scaffold. Background Art
[0002] The attached lifting scaffold is a tool-type scaffold used in construction and installed on the facade of a building or structure. Its main function is to provide a working platform and edge protection for construction workers.
[0003] Since the fulcrums of the scaffolding frame are all on the building structure and the scaffolding frame can be raised and lowered along the facade of the building or structure, there is no need to erect the frame from the bottom to the top. Therefore, it is more suitable for use in high-rise building construction. The guide rail structure of the lifting scaffolding in the prior art is relatively simple, and there is a lack of an anti-fall structure for the lifting scaffolding on the guide rail. The anti-fall effect is achieved by relying solely on the brake structure of the climbing motor. When the climbing motor is accidentally powered off, the lifting scaffolding may fall due to the failure of the built-in brake structure, resulting in insufficient safety. Therefore, it is necessary to design an anti-fall rail for the lifting scaffolding to address the above problems. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes an anti-falling guide rail for a lifting scaffold.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] The anti-fall guide rail of the lifting scaffolding comprises a fixed plate, the outer wall of the fixed plate is provided with a plurality of fixing holes, the outer wall of the fixed plate is fixedly installed with a guide rail body, the outer walls on both sides of the guide rail body are fixedly installed with a plurality of blocking columns through connecting grooves, the outer wall of the guide rail body is fixedly installed with a sliding rod through a moving groove, the outer wall of the sliding rod is slidably installed with a moving block through a limiting mechanism, the bottom wall of the moving block is fixedly installed with a connecting shaft through a connecting mechanism, the outer walls at both ends of the connecting shaft are rotatably installed with clamping blocks through connecting sleeves, the end of the moving block is fixedly installed with a connecting plate, the inner wall of the connecting plate is fixedly connected with two extrusion plates through a telescopic mechanism, the outer wall of the sliding rod is slidably installed with a buffer plate, and the bottom wall of the buffer plate is connected to the inner bottom wall of the moving groove through a buffer mechanism.
[0007] Preferably, the limiting mechanism comprises a limiting rod fixedly installed inside the moving groove, and the limiting rod slides through the moving block.
[0008] Preferably, the connection mechanism comprises a connection block fixedly mounted on the bottom wall of the moving block, and the connecting shaft passes through the connection block.
[0009] Preferably, the telescopic mechanism comprises a cylinder fixedly mounted on the inner wall of the connecting plate, and the telescopic end of the cylinder is fixedly connected to the outer wall of the extrusion plate.
[0010] Preferably, the buffer mechanism comprises a buffer spring installed on the outer wall of the slide rod, and two ends of the buffer spring are elastically connected to the inner bottom wall of the moving groove and the bottom wall of the buffer plate.
[0011] Preferably, two friction plates are fixedly mounted on the outer wall of the guide rail body, and a plurality of friction blocks are fixedly mounted on the outer walls of the two friction plates and the inner walls of the two extrusion plates.
[0012] Beneficial effects of the utility model:
[0013] 1. By setting up components such as stopper columns, connecting shafts, connecting sleeves and clamping blocks, the moving block drives the connecting shaft to move downward through the connecting block, and the connecting shaft then drives the clamping block to move downward through the connecting sleeve and contact the stopper column. Through the obstruction of multiple stopper columns, the clamping block can rotate on the outer wall of the connecting shaft through the connecting sleeve. At this time, the force of falling can be buffered through the effect of resistance to avoid direct falling and safety accidents.
[0014] 2. By setting up components such as an extrusion plate, a friction plate and a friction block, the cylinder drives the extrusion plate to contact the friction plate. The friction between multiple friction blocks can increase the resistance during falling, thereby reducing the speed during falling. When the friction block is worn due to friction, the cylinder drives the extrusion plate to gradually approach the friction plate, thereby ensuring the friction between the two and ensuring that the friction can generate sufficient resistance.

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-5 The anti-fall guide rail of the lifting scaffold comprises a fixed plate 1, a plurality of fixing holes are opened on the outer wall of the fixed plate 1, a guide rail body 2 is fixedly installed on the outer wall of the fixed plate 1, a plurality of blocking columns 3 are fixedly installed on the outer walls of both sides of the guide rail body 2 through connecting grooves, a slide rod 4 is fixedly installed on the outer wall of the guide rail body 2 through a moving groove, a moving block 6 is slidably installed on the outer wall of the slide rod 4 through a limiting mechanism, the limiting mechanism comprises a limiting rod 5 fixedly installed inside the moving groove, the limiting rod 5 slides through the moving block 6, the limiting rod 5 can limit the moving block 6 so that it can only move axially along the outer wall of the slide rod 4, thereby ensuring that the connecting plate 11 and the guide rail body 2 are in a parallel state, and a connecting shaft 8 is fixedly installed on the bottom wall of the moving block 6 through a connecting mechanism, the connecting mechanism comprises a connecting block 7 fixedly installed on the bottom wall of the moving block 6, and the connecting shaft 8 passes through the connecting block 7.
[0023] The outer walls of both ends of the connecting shaft 8 are rotatably installed with a clamping block 10 through a connecting sleeve 9, a connecting plate 11 is fixedly installed at the end of the moving block 6, and the inner wall of the connecting plate 11 is fixedly connected with two extrusion plates 13 through a telescopic mechanism. The telescopic mechanism includes a cylinder 12 fixedly installed on the inner wall of the connecting plate 11, and the telescopic end of the cylinder 12 is fixedly connected to the outer wall of the extrusion plate 13. Two friction plates 14 are fixedly installed on the outer wall of the guide rail body 2, and multiple friction blocks 15 are fixedly installed on the outer walls of the two friction plates 14 and the inner walls of the two extrusion plates 13. A buffer plate 17 is slidably installed on the outer wall of the slide rod 4, and the bottom wall of the buffer plate 17 is connected to the inner bottom wall of the moving groove through a buffer mechanism. The buffer mechanism includes a buffer spring 16 installed on the outer wall of the slide rod 4, and both ends of the buffer spring 16 are elastically connected to the inner bottom wall of the moving groove and the bottom wall of the buffer plate 17.
[0024] When the utility model is used, the fixing plate 1 is fixedly installed by the cooperation of the fixing hole and the fixing bolt, thereby completing the fixed installation of the guide rail body 2. When falling occurs, the moving block 6 slides on the outer wall of the slide rod 4 by cooperating with the limit rod 5. At this time, the moving block 6 drives the connecting shaft 8 to move downward through the connecting block 7, and the connecting shaft 8 drives the clamping block 10 to move downward through the connecting sleeve 9 and contact the blocking column 3. Through the obstruction of multiple blocking columns 3, the clamping block 10 can be rotated on the outer wall of the connecting shaft 8 through the connecting sleeve 9. At this time, the force of falling can be buffered by the effect of resistance. At the same time, the connecting plate 11 can drive the extrusion plate 13 to contact the friction plate 14 through the cylinder 12. The friction between the multiple friction blocks 15 can increase the resistance during falling, thereby reducing the speed during falling.
[0025] When the friction block 15 is worn due to friction, the cylinder 12 drives the extrusion plate 13 to gradually approach the friction plate 14, thereby ensuring the friction between the two and ensuring that the friction can generate sufficient resistance. When the moving block 6 continues to slide downward on the outer wall of the slide bar 4, the bottom wall of the moving block 6 can contact the upper end surface of the buffer plate 17. The buffer plate 17 is forced to slide downward on the outer wall of the slide bar 4 and squeeze the buffer spring 16. The buffer spring 16 is deformed under force to absorb the applied force. The veteran buffers the applied force by releasing elastic potential energy, thereby avoiding damage to the equipment caused by the impact force under the line during falling.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
