Description

Technical Field

[0001] The invention relates to the field of scaffolds, in particular to an attached lifting scaffold. Background Art

[0002] At present, there are more and more high-rise and super-high-rise building structures, which has led to the rapid promotion of lifting scaffolding. The commonly used ordinary coupler-type steel pipe scaffolding can no longer meet the market demand and is gradually being eliminated from the construction market. The demand for new types of building scaffolding has increased greatly. Therefore, it is necessary to invest in the research and development and production of attached lifting scaffolding.

[0003] After searching, a Chinese patent application with application publication number CN112144857A discloses an attached lifting scaffold, including a main frame, which is arranged on the outside of the building body, and a wall-attached support is fixedly installed on the building body. The main frame is connected to the building body through the wall-attached support and can be lifted and lowered along the building body. A lifting device is provided between the main frame and the wall-attached support to provide lifting power for the main frame; the lifting scaffold is generally no more than five stories high, and can be raised from the ground to the top floor of the structure according to the construction progress, saving a large amount of steel pipes, fasteners and other materials, and reducing production costs; the anti-fall device is provided to effectively prevent the frame from falling, thereby ensuring the safety of the scaffold.

[0004] When the existing attached lifting scaffold is in use, multiple workers will stand on the pedals. Since the workers' standing positions are random, the forces acting on the pedals are different. As the height of the pedals increases, the pedals tend to tilt to one side due to the different forces acting on them, which reduces the stability of the scaffold and increases the risk factor of using the scaffold.

[0015] The beneficial effects of the present invention are:

[0016] The present invention provides a support mechanism and a protective mechanism. When a plurality of workers stand on the support plate when using the attached lifting scaffold, the support plate will move downward under the action of the workers' gravity, and the third spring and the protective pad can play a role in buffering and shock-absorbing the workers' standing, thereby facilitating the protection of the workers. At the same time, due to the difference in gravity of the workers, the support plate moves downward to different heights. Since the plurality of support plates are independently distributed, compared with the support plate set as a whole, the plurality of support plates set independently can independently support different workers, thereby preventing the support plate from being subjected to different pressures due to the difference in the weight of the workers, thereby causing the support plate to deform to one side. In addition, when the support plate moves downward, it will squeeze the protective pad. At this time, the counterweight liquid inside the protective pad will be transported to the inside of the remaining protective pads through the conduit, thereby facilitating the counterweight treatment of the scaffold, so as to improve the stability of the scaffold, and effectively prevent the difference in force on the pedal due to the random standing position of the workers, thereby causing the pedal to have a tendency to tilt to one side, which will reduce the stability of the scaffold and increase the risk factor of the scaffold.

[0017] The present invention is provided with a raised portion, a limiting ring, a buffer pad, a cavity, an insert ring, a receiving groove and a connecting groove. When the pedal is towed by the traction mechanism, the traction hook is hung on the traction ring, and one side of the traction ring is restricted inside the raised portion. As the traction mechanism pulls the pedal, the traction ring exerts a certain pressure on the limiting ring, and the limiting ring drives the buffer pad to be squeezed to one side under the action of the pressure. After being squeezed, the gas inside the buffer pad is transported to the inside of the cavity through the through hole. At this time, the gas inside the cavity is transported to the inside of the receiving groove through the air hole. The internal air pressure of the receiving groove is increased due to the input of the gas. The insert ring is extended from the inside of the receiving groove under the action of the air pressure and inserted into the inside of the connecting groove. The insertion depth of the insert ring in the connecting groove is increased as the number of staff increases, thereby facilitating the improvement of the firmness between the traction hook and the traction ring, facilitating the lifting and lowering of the scaffold, and preventing the traction hook and the traction ring from falling off, thereby increasing the risk factor of the scaffold and being detrimental to the use of the scaffold.

A protective pad 40 is provided between the multiple support plates 39 and the pedal 7, and the protective pad 40 is a hollow elastic material. The interior of the protective pad 40 is filled with a counterweight liquid. A conduit 41 is provided between the multiple protective pads 40, and a protective mechanism 6 is provided on the top of the pedal 7, and the support mechanism 11 is located inside the protective mechanism 6. A traction mechanism 4 is provided at the top position between one side of the two guide rails 1. When using the attached lifting scaffold, multiple workers When the worker stands on the support plate 39, the support plate 39 will move downward under the action of the worker's gravity, and the third spring 42 and the protective pad 40 can buffer and reduce shock for the worker's standing, thereby facilitating the protection of the worker. At the same time, due to the difference in gravity of the workers, the support plate 39 moves down to different heights, and since the multiple support plates 39 are independently distributed, compared with the support plates 39 set as a whole, the multiple support plates 39 set independently can independently support different workers, thereby preventing the weight of the workers from being affected. The difference causes the support plate 39 to be subjected to different pressures, causing the support plate 39 to deform to one side. In addition, when the support plate 39 moves downward, it will squeeze the protective pad 40. At this time, the counterweight liquid inside the protective pad 40 will be transported to the inside of the remaining protective pads 40 through the conduit 41, thereby facilitating the counterweight treatment of the scaffolding, so as to improve the stability of the scaffolding, and effectively prevent the pedal 7 from having a tendency to tilt to one side due to the difference in the standing position of the workers, which will reduce the stability of the scaffolding and increase the risk factor of the scaffolding.

When the scaffold needs to be lifted or lowered, the motor 27 is started, and the motor 27 will drive the rotating rod 25 to rotate, so that the winding wheel 26 reels the traction rope 28, so as to facilitate the scaffold to be lifted or lowered by the traction mechanism 4.
