Description

Technical Field

[0001] This utility model belongs to the field of lifting equipment technology, specifically relating to a fall-proof lifting platform. Background Technology

[0002] A lifting platform is a piece of equipment that facilitates high-altitude operations for construction workers. For example, Chinese utility model patent document CN222834751U discloses a rotating lifting platform for the passage of machinery and materials. To ensure the safety of construction workers, they must wear full-body safety harnesses during construction.

[0003] Currently, there is no structure specifically designed for mounting full-body safety harnesses on lifting platforms. Instead, the hooks for full-body safety harnesses are usually attached to the platform's guardrails. However, the guardrails of lifting platforms are typically limited in height, which can easily lead to the harness getting too low and causing excessive falls. Furthermore, the fixed hooks restrict the movement of construction workers.

[0004] Therefore, it is necessary to design a fall-prevention lifting platform that can ensure the hanging height, avoid low hanging, and reduce the impact on the activities of construction workers to solve the current technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fall-prevention lifting platform that ensures proper mounting height, avoids low mounting, and reduces the impact on construction workers' activities.

[0006] The technical solution of this utility model is as follows: a fall-prevention lifting platform, including a construction platform, a scissor lift mechanism at the bottom of the construction platform, guardrails around the top of the construction platform, an adjustable column at the center of the top of the construction platform, a rotating cylinder at the top of the adjustable column that can rotate and slide, a crossbeam fixedly installed on the outside of the rotating cylinder, and lifting rings at the bottom of both ends of the crossbeam; a fall-locking mechanism is provided between the bottom of the rotating cylinder and the adjustable column.

[0007] Furthermore, the drop locking mechanism has a support plate fixedly mounted on the adjustable column, the support plate and the rotating cylinder are elastically supported, the top of the support plate has a circumferential array of lower teeth, and the bottom of the rotating cylinder has a circumferential array of upper teeth that cooperate with the lower teeth.

[0008] Furthermore, a baffle is fixedly provided on the top of the support plate, the lower tooth is provided at the upper end of the baffle, an upper stop is provided at the bottom end of the rotating cylinder, and the upper tooth is provided at the lower end of the upper stop.

[0009] Furthermore, the upper baffle and the inside of the baffle cylinder are provided with a spring fitted onto the upper end of the adjustable column.

[0010] Furthermore, the adjustable column has a support cylinder, and a support rod is threaded onto the upper end of the support cylinder. The upper end of the support rod has an optical axis. The rotating cylinder rotates and slides on the outside of the optical axis, and a limit plate is fixedly provided at the top end of the optical axis.

[0011] Furthermore, handles are fixedly provided on both sides of the support rod.

[0012] Furthermore, a connecting plate is fixedly installed at the bottom of the adjustable column, and the connecting plate is detachably and fixedly connected to the top of the construction platform.

[0013] Furthermore, the lifting ring is a U-shaped lifting ring welded and fixed to the bottom of the crossbeam.

[0014] Furthermore, a stiffening plate is fixedly provided between the bottom of the crossbeam and the side of the rotating cylinder.

[0015] The beneficial effects of this utility model are:

[0016] (1) In this utility model, the hook of the full-body safety belt worn by the construction worker is connected to the lifting ring, and the adjustable column provides support to the crossbeam so that the lifting ring has a certain height and avoids the safety hazard of the hook hanging low.

[0017] (2) By adjusting the height of the adjustable column, the crossbeam can have different heights, so that the height of the crossbeam is moderate and suitable for construction workers of different heights.

[0018] (3) The crossbeam can rotate as the construction workers move on the construction platform, so that the lifting rings can move with the construction workers, reducing the impact on the construction workers' activities;

[0019] (4) When a construction worker falls, the fall locking mechanism locks the rotating cylinder and the adjustable column, preventing the crossbeam from rotating relative to the adjustable column, thus reducing the risk of injury to the construction worker when falling.
