Description

Technical Field

[0001] The utility model relates to the technical field of lifting scaffolds, in particular to a guide seat of an attached lifting scaffold. Background Art

[0002] With the acceleration of the urbanization process, the number of high-rise buildings has increased year by year. Especially in cities with limited floor area, high-rise buildings have become an important choice to make full use of space. In traditional scaffolds, as the building gradually rises, construction workers must manually erect and dismantle the scaffolds, which not only consumes a large amount of time and human resources, but also increases the safety risks during the construction process. In order to improve the construction efficiency and reduce potential safety hazards, the attached lifting scaffold system has emerged. This scaffold system realizes automatic lifting through guide rails and guide seats installed on the building structure, which not only reduces the number of times of erecting the scaffold, but also improves the construction safety.

[0003] In the attached lifting scaffold system, the guide seat is one of the key components. Its main function is to fix the scaffold on the building structure and drive the scaffold to lift synchronously with the construction progress through a hydraulic system or a mechanical device. However, during long-term use, there is a certain risk of the scaffold falling. If the fall prevention cannot be stopped in time, it is very easy to cause extensive damage to personnel and materials. Summary of the Utility Model

The anti-falling pin shaft 7 is installed at the middle upper position of the anti-falling swing block 8. On both sides inside the base 1, torsion spring pin shafts 10 are respectively provided. On both ends of the anti-falling pin shaft 7, torsion springs I 11 are respectively provided. Both ends of the torsion spring I 11 are respectively connected to the anti-falling pin shaft 7 and the torsion spring pin shaft 10. An excitation tooth 9 is provided on the front side of the anti-falling swing block 8. A limit pin shaft I 12 is provided at the upper position behind the anti-falling pin shaft 7 inside the base 1. Reset structures are respectively provided on both sides of the lower end of the anti-falling swing block 8. The front end of the base 1 is installed with a roller frame 5. Several rollers 6 are symmetrically installed on the inner side of the front end of the roller frame 5.

[0020] The reset structure includes a reset pin shaft 13 rotatably installed on the side of the anti-falling swing block 8. A torsion spring II 16 is provided on the reset pin shaft 13. Both ends of the torsion spring II 16 are respectively connected to the reset pin shaft 13 and the anti-falling swing block 8. A reset swing block 14 is installed on the top end of the reset pin shaft 13. A limit pin shaft II 15 is provided on the inner wall of the base 1 at the position below the head of the reset swing block 14.

[0021] On both sides of the rear plate of the base 1, protruding ear-shaped structures are respectively provided, and several bolt holes are opened in the middle of the rear plate of the base 1.

[0022] The principle and usage process of the present utility model:

[0023] First, install the guide base onto the cast wall through the bolt holes on the rear plate of the base 1. Place the scaffold guide rail to be lifted in front of the guide base. Remove the roller frames 5 on both sides and reinstall them so that the rollers 6 are located in the chute on both sides of the guide rail. Adjust the angle and length of the load-unloading top support 2 so that the ladder step of the guide rail is caught in the top of the load-unloading top support 2, enabling the load-unloading top support 2 to support the ladder step, thus completing the installation.

[0024] During use, use a hoisting device to drive the scaffold and the guide rail to move upward. At this time, the rollers 6 guide the vertical direction of the guide rail to prevent skew. At the same time, the guide rail moves upward relative to the guide base. The ladder step of the guide rail touches the excitation tooth 9 during the movement, as Figure 3At the observed angle shown, after the excitation tooth 9 is hit upward and moves upward, the anti-falling pendulum block 8 rotates clockwise along the anti-falling pin shaft 7, and then drives the reset pendulum block 14 to hit the second limit pin shaft 15. During the impact, the second torsion spring 16 accumulates elastic force. As the excitation tooth 9 leaves the ladder stop, the elastic force of the second torsion spring 16 is released, pushing the reset pendulum block 14 to rotate clockwise, causing the anti-falling pendulum block 8 to start rotating in the reverse direction. Since the weight of the lower end of the anti-falling pendulum block 8 is greater than that of the upper end, when rotating in the reverse direction, affected by gravity and the resistance of the first torsion spring 11, the anti-falling pendulum block 8 will gradually decelerate and then fall, and is bounced up by the second torsion spring 16 again, or when the excitation tooth 9 contacts the next ladder stop, the anti-falling pendulum block 8 is pressed and rotated again. Thus, during the upward lifting process of the scaffolding, the anti-falling pendulum block 8 can swing cyclically. When the upward lifting speed is relatively fast, the swing amplitude of the anti-falling pendulum block 8 will also increase correspondingly. The first limit pin shaft 12 limits the anti-falling pendulum block 8 to prevent it from rotating excessively;

[0025] In case of an accident and the scaffolding falls, due to the continuous swinging of the anti-falling pendulum block 8, its top will intermittently protrude forward. When the scaffolding falls, it inserts into the ladder stop, and its rear end abuts against the first limit pin shaft 12, thereby quickly locking the scaffolding to stop the fall. Even if the top of the anti-falling pendulum block 8 does not swing forward when an accident occurs, when the guide rail ladder stop of the scaffolding falls, it will also push the excitation tooth 9 downward, forcing the anti-falling pendulum block 8 to rotate, so that the top of the anti-falling pendulum block 8 swings forward and inserts into the upper ladder stop to achieve fall prevention and ensure safety.
