Underground construction protection device convenient to move and adjust and with high safety coefficient

Abstract

The invention relates to an underground construction protection device convenient to move and adjust and with a high safety coefficient. The underground construction protection device comprises a topplate, a movement mechanism, an adjustment mechanism, two side plates and four supporting legs, wherein the movement mechanism comprises a driving assembly and four movement assemblies; the adjustmentmechanism comprises four adjusting assemblies; the driving assembly comprises a handlebar, a rotary table, a first screw rod, a movement block and a rotary assembly; the rotary assembly comprises a vertical rod, a sliding ring, a connecting rod, a supporting rod, universal wheels and two transverse rods. According to the underground construction protection device convenient to move and adjust andwith the high safety coefficient, provided by the invention, the movement mechanism drives the universal wheels to move downward so that the universal wheels are in contact with the ground and equipment is convenient to move according to changes of construction sites; moreover, the adjustment mechanism drives the side plates to rotate on channels with different sizes and the side plates abut against an inner wall of the channel, so that fragments at the top of the channel are prevented from hitting constructors and the personal safety is protected, and furthermore, the safety coefficient of the equipment is improved.

Description

technical field [0001] The invention relates to the field of geological underground construction safety protection equipment, in particular to an underground construction protection device with a high safety factor that is easy to move and adjust. Background technique [0002] With the rapid development of the city, while the city is expanding outwards, it is also extending downwards, and the design and utilization of underground space has been paid more and more attention. Correspondingly, disasters of various geological and underground projects also follow one after another. In underground construction, it is generally necessary to form a construction channel. Because it is underground, some soil debris and underground water seepage often fall from the top of the channel during construction. , affecting the normal construction of the builders, if the volume and weight of the falling debris is large, it may also pose a threat to the personal safety of the construction worke...

Problems solved by technology

Correspondingly, disasters of various geological and underground projects also follow one after another. In underground construction, it is generally necessary to form a construction channel. Because it is underground, some soil debris and underground water seepage often fall from the top of the channel during construction. , affect the normal construction of the constructors, if the volume and weight of the fallen debris is large, it may also pose a threat to the personal safety of the construction workers

[0003] In order to ensure safe construction, people usually install various wall panels on the top of the passage to prevent debris from falling on the top of the passage. However, when using this method for protection, on the one hand, due to the long passage, it takes a lot of cost to build protection On the other hand, when the wallboard is not installed securely, it will also fall from the top of the channel, posing a threat to the personal safety of the construction personnel in the channel, resulting in a low safety factor for the existing underground construction device, which cannot guarantee construction personal safety of personnel
