specific Embodiment approach

[0063] The two bases 13 are placed at the position where the bottom surface of the foundation pit is close to the sidewall of the foundation pit and are arranged oppositely;

[0064] Insert the protruding rod 114 of the support rod 11 into the jack of the base 13, turn the third rotating shaft 133 on the top surface of the base 13, so that the driving gear 1331 of the third rotating shaft 133 rotates, and then the transmission belt 134 drives the driven gear 1322 to rotate to drive The second rotating shaft 132 rotates, and the second rotating shaft 132 drives the transmission block 1321 to rotate. The transmission block 1321 drives the fixed rod 131 to move towards the direction close to the protruding rod 114 through threads, so that the fixed rod 131 is inserted into the through hole of the protruding rod 114, which can prevent the protruding rod 131 from protruding. Rod 114 escapes from the socket, so as to achieve the purpose of fixedly connecting support rod 11 and base 1...

Abstract

The invention relates to a protection device in a foundation pit. The protection device comprises two bases, supporting rods, inclined struts and a protection net, and the bases are oppositely arranged on the bottom face of the foundation pit; the supporting rods are vertically arranged and detachably mounted on the bases; the lengths of the inclined struts are adjustable, one ends of the inclined struts are rotationally connected to the bases, the other ends of the inclined struts are rotationally connected to the supporting rods in a position-adjustable mode, and the included angle between the inclined struts and the supporting rods is changed by adjusting the position of the corresponding ends of the inclined struts along the supporting rods and correspondingly adjusting the lengths of the inclined struts; and the protection net is connected between the two opposite supporting rods. The problem that potential safety hazards of operators in the foundation pit are large is effectively solved, the protection device is arranged at the position, close to the side wall, in the foundation pit, so that the operators are prevented from being injured by falling broken stones and sundries, the potential safety hazards are reduced, and the safety of the operators is guaranteed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a protection device in a foundation pit. Background technique [0002] During the construction of some foundation pits, due to the poor soil properties of the area, problems such as falling of gravel are prone to occur. In addition, some construction sites are not standardized, and mechanical equipment, accumulated soil, construction materials, etc. are piled up around the ground on the top of the foundation pit. Debris, these debris are easy to fall into the foundation pit, these problems have great safety hazards to the workers inside the foundation pit, and it is difficult to guarantee the construction safety. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a protection device in the foundation pit, which solves the problem of relatively large safety hazards for the operators inside the found...
