Description

Technical Field

[0001] The utility model relates to the technical field of under-supported platforms, in particular to an under-supported elevator steel platform. Background Art

[0002] In today's construction sites, construction elevators have long been popularized. The use of construction elevators can greatly save labor costs and time costs, and can quickly and accurately send workers and tools to the target floor. However, using construction elevators to transport construction materials between separated floors will inevitably take up the time of the construction elevator, thereby slowing down the construction process. This requires the use of a down-supported elevator steel platform, so the existing down-supported elevator steel platform has been continuously innovated and developed. It can be seen that the current down-supported elevator steel platform basically meets people's needs, but there are still some problems.

By setting the columns and the connecting plates, the equipment can be free from installation, cost saving, safety and reliability, and reduces the cost increased by erecting scaffolding and safety protection.

[0004] However, when the above-mentioned device is actually installed and used, since the columns and connecting plates of the device are fixedly connected, it can be directly placed between the elevator shaft and the floor for construction. However, the purpose of using the elevator on each floor is different, and the widths of the elevator shaft and the elevator are also different. This causes the width of the platform of the device to be different from the width of the elevator shaft when the platform is overlapped, causing the platform built by the device to tilt, thereby posing a hidden danger. Therefore, there is an urgent need for a bottom-supported elevator steel platform to solve the above problem. Utility Model Content

[0009] As a preferred technical solution of the utility model, the two sides of the top of the push plate are threadedly connected with a second hand wheel, and the bottom of the second hand wheel is threadedly connected to the inner wall of the thread groove.

[0010] As a preferred technical solution of the utility model, one end of the sliding rod is fixedly connected to a limiting plate, and one side of the limiting plate is overlapped with the inner wall of the supporting platform.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model drives the movable plate on one side to move by rotating the hand wheel. The movement of the movable plate makes one side fit against the inner wall of the elevator passage, thereby applying pressure to the inner wall of the elevator passage. After the movable plate moves to the inner wall of the elevator passage, one side of the hand wheel is supported. After the hand wheel is supported by the movable plate, it pushes the supporting platform to tilt, thereby adjusting the horizontal angle of the supporting platform, so that the staff can work more smoothly on the supporting platform, and the width of the supporting platform is extended by the movement of the movable plate, so that the supporting platform can better adapt to elevator passages of different widths, thereby improving the practicability of the equipment.

[0017] 2. The utility model pushes the movable plate and then pushes the push plate on the top to move, then pushes one side of the push plate to the top of the movable plate, and then uses a hand wheel to fix the push plate to the top of the movable plate, thereby expanding the range of the top of the support platform, and the structure can fill the extended gap according to the extended width of the support platform, thereby avoiding the safety hazards caused by the gap.
