Description

A kind of auxiliary device for lifting early warning protection of board used in construction site

technical field

The invention relates to the technical field of construction, in particular to an auxiliary device for lifting, early warning and protection of boards used in construction sites.

Background technique

Plates generally refer to soft flat materials with a thickness of more than 2 mm and hard flat materials with a thickness of more than 0.5 mm, and also refer to forged, rolled or cast metal plates. Building boards, because of their particularity, tend to be thicker.

With the rapid development of China's economy, various large-scale projects have begun to be constructed, and there are more and more construction sites. In construction sites, the importance of building boards is self-evident. Because of their own weight, building boards are also used to improve work efficiency. Efficiency, it is usually suspended by a suspension device. Due to the weight of the board on the construction site, and the working time of the construction site is too long, the bayonet of the suspension device is prone to slack, and the board may fall from the bayonet in the middle of the suspension. , There is a great potential safety hazard. These suspension devices do not have alarm devices, and it is difficult for workers to discover the problems of the suspension devices at the first time and make advance judgments.

Therefore, in view of the above situation, we propose an auxiliary device for early warning and protection of board lifting for construction sites, which has the advantages of ensuring that the board will not fall if the board is loose in the middle of the suspension, and can also make an alarm in advance.

beneficial effect

Compared with the prior art, the present invention provides an auxiliary device for lifting, early warning and protection of panels for construction sites, which has the following beneficial effects:

1. The construction site uses the board lifting early warning protection auxiliary device. When in use, the building board is clamped in the clamping port and in the clamping block. When the building board is clamped in the clamping block, the clamping block will be pushed toward the clamping block. When the two sides are spread apart, the clamping rod will move in the opposite direction to abut, and the alarm buckles on it will be firmly abutted together without making a sound; on the contrary, when the clamping block does not clamp the building board, The alarm buckles on the clamping rod will not abut together. When the plate is suspended, when the device is started, the alarm buckle will collide with the clamping rod during the movement, and an alarm sound will be issued, so as to facilitate the operation of the clamping rod. Workers discover problems in a timely manner and take early precautions to prevent accidents.

2. The construction site uses the board lifting early warning protection auxiliary device. When the board is not clamped tightly and the workers do not find it, the board gradually slides down in the clamping block during the suspension process, and as the board gradually slides down , drive the rotation of the first gear and the second gear arranged in the clamping rod, and then drive the rotation of the first sector gear and the second sector gear meshed with it, and the first shaft rod and the second shaft rod connected to it. Then the relative movement is carried out, and the connecting block connected to it is driven to clamp the building board, and the clamping teeth set on the block firmly clamp the building board, so as to avoid the safety hazard caused by the falling of the building board.
