Lifting and folding building construction protection fence

Abstract

The invention belongs to the technical field of guardrails, and specifically relates to a lifting and folding building construction guardrail, including upright columns, connecting columns, support seats, shielding cloth, casters, worm wheels, worms, screw rods, sliding rods, connecting blocks, and guide columns , the scissors mechanism, the connecting rod and the No. 1 telescopic shaft; the present invention drives the scissors mechanism and the No. 1 telescopic shaft to expand by pulling the handle on the column, and realizes the lateral expansion of the guardrail. By rotating the worm, the worm drives the worm wheel to rotate , the worm wheel drives the screw to rotate, the screw drives the sliding rod to slide in the sinking groove, the sliding rod drives the No. 1 telescopic shaft to move upward, and the No. 1 telescopic rod drives the covering cloth to move, realizing the adjustment of the vertical height of the guardrail , to separate the construction area from the outside world, thereby avoiding the dust and gravel generated in the construction area from causing harm to pedestrians and vehicles outside the guardrail, and at the same time meeting the needs for guardrails of different heights and increasing the protection The scope of use of the column.

Description

technical field [0001] The invention belongs to the technical field of guardrails, in particular to a lifting and folding building construction guardrail. Background technique [0002] Fences can be seen everywhere in our lives. Fences are widely used in municipal engineering, transportation, communities, ports, airports, storage area maintenance and construction, etc., to protect and protect personal safety, equipment and facilities, and isolate and protect construction sites. [0003] There are many protective fences on the existing building construction site for isolation and protection of the construction site. Most of them are isolated by iron sheets or walls. Although these isolation methods can isolate dust, due to the limited height of the iron sheets or walls, when large machinery During construction, the height of the dust raised increases, and the dust is very easy to cross the iron sheet of the fence or the wall, making the surrounding environment worse.
