Description

Technical Field

[0001] The utility model relates to the technical field of construction safety, in particular to an assembled construction safety anti-falling component. Background Art

[0002] Construction is a basic activity in urban construction. Specifically, it refers to the reasonable construction sequence that a construction project or unit project should follow during the construction process. Construction projects include production, life, main body, supporting facilities, gardens, greening, roads and various pipelines. During the construction phase, due to the different heights of the buildings being constructed, upper and lower lifting platforms are often installed on the outside of the main building to facilitate the activities of construction workers and the transportation of materials. Various protective mechanisms will be installed around the lifting platform to provide protection for the construction workers' bodies and prevent them from falling from the platform due to sudden accidents when the lifting platform is rising. Therefore, in the specific construction phase, construction safety anti-fall components are indispensable equipment during the construction phase.

The construction safety anti-falling device, through the matching test of the connecting rod and the sleeve ring and the connecting plate and the rope ring, makes the construction safety anti-falling device fixedly connected with the connecting rod between the two sets of fixed seats. After entering the lifting platform, the staff can wrap the safety rope worn on the body around the rope ring, and the sleeve ring and the rope ring are connected by a connecting plate, thereby further improving the protection effect on the staff. At the same time, the sleeve ring can slide on the outside of the connecting rod, thereby ensuring the range of activities of the staff and ensuring the practicality of the construction safety anti-falling device.

Therefore, when the transmission slider 306 drives the surrounding rod 204 to move up and down, the surrounding rod 204 drives the sliding block 403 to slide up and down on the inner side of the sliding groove 402.

[0036] Working principle: First, start the driving motor 5 through the control panel, and the output end of the driving motor 5 drives a set of No. 2 bevel gears 305 to rotate. When the No. 2 bevel gears 305 rotate, it drives the transmission rod 309 to rotate. The transmission rod 309 drives another set of No. 2 bevel gears 305 to rotate synchronously. When the No. 2 bevel gears 305 rotate, they mesh with the two sets of No. 1 bevel gears 304, and the two sets of No. 1 bevel gears 304 rotate synchronously.

[0037] Secondly, when the two sets of first bevel gears 304 rotate, the corresponding threaded rod 303 is driven to rotate. Through the thread structure relationship between the transmission slider 306 and the threaded rod 303, the threaded rod 303 drives the transmission slider 306 to move vertically upward, and the transmission slider 306 drives the surrounding rod 204 to move upward;

[0038] Finally, when the fence 204 moves, it drives the sleeve rod 203 to slide and rise inside the support rod 201 until the length formed by the support rod 201 and the sleeve rod 203 is adjusted to the height suitable for the construction personnel, and then the drive motor 5 is turned off through the control panel to complete the work.
