A bridge construction protection device

Abstract

The invention discloses a bridge construction protection device, which comprises a first lifting rod, a clip, a protective plate, and a second lifting rod. The first lifting rod is parallel to the second lifting rod arranged on the side, and the first lifting rod , The side of the second lifting rod is connected with a clip, which is matched with the protective plate. The clip includes a starting structure, a moving block, an electromagnet, a permanent magnet, a fixed block, and a guiding structure. The fixed block is connected to the side of the first lifting rod. The fixed block is provided with a guiding structure, the moving block is arranged on the fixed block, the moving block is connected with the guiding structure, the top of the moving block is provided with a starting structure, and the bottom of the moving block is embedded with an electromagnet. The beneficial effect of the present invention is: The cooperation with the moving block can make the height adjustment of the clamp, which is not only convenient to insert the protective plate, but also can automatically adapt to the card slot of the protective plate, so that there is no gap in the clamping connection, which can achieve the effect of convenient installation, thereby improving work efficiency, and The fixing effect is better and prevents shaking.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a bridge construction protection device. Background technique [0002] In the process of bridge construction, most of the construction workers work at heights, so good bridge construction protection devices are needed to ensure the personal safety of the construction workers. In the prior art, protective nets are usually used for protection. The protective nets are easy to break and the protection effect is poor. [0003] The prior art patent number is CN201910514874.1 for a bridge construction protection device, which includes an upper column, a protective plate installation insert, a protective plate and an installation base; the lower end of the upper column is fixedly connected to the lifting mechanism, and the lower part of the lifting mechanism is fixed on the lower part On the column; the left and right sides of the lifting mechanism are also equipped with a guide mechan...

Problems solved by technology

The invention is simple in structure, low in cost, quick and convenient to install the protective plate, and can adjust the height of the whole device at the same time, has strong practicability and good protective effect. It is easy to manually adjust the angle, which is a waste of installation time. If there is a gap after the card is inserted, it will easily cause the anti-skid plate to shake and become unstable.
