Problems solved by technology

It mainly has the following defects: the disassembly process is cumbersome, labor-intensive and time-consuming; there is no safety protection device; the reuse rate is low, material waste, etc.
[0015] Through the investigation of the prior art, it is found that the stairs used as the upper and lower deep foundation pits are installed layer by layer according to the depth of the deep foundation pit and cannot be retracted, so there are the following deficiencies: the construction depth of the deep foundation pit is constantly changing, When the depth of the deep foundation pit cannot satisfy the installation of one of the stairs, it needs to be compensated by the external horseway

Abstract

The invention relates to a deep foundation pit up-down stair and a telescopic supporting part and suspension part for the stair. The telescopic supporting part limits the working space of the up-down stair and provides support for a footpath unit formed by footpaths. The telescopic supporting part is characterized by comprising a plurality of telescopic rods, wherein an electromagnetic flow valve is arranged between each telescopic rod and a hydraulic oil way of a hydraulic system; the elongation or shortening amount of the telescopic rods can be adjusted by adjusting the opening degree of the electromagnetic flow valves or adjusting the hydraulic pressure; the slope angle of the footpaths and the height of the up-down stair are adjusted based on the elongation or shortening amount of the telescopic rods; oil inlet holes and oil outlet holes are formed in the side walls of telescopic short sections at the two ends of the telescopic rods; and the oil inlet holes and the oil outlet holes are in sealed connection with pipelines in a hydraulic loop.

Description

[0001] The present invention is an application number 201811380067.7, the application date is November 20, 2018, the application type is invention, and the application name is a divisional application for hanging up and down stairs in deep foundation pits. technical field [0002] The invention belongs to the technical field of construction engineering, and relates to a device for going up and down stairs in construction, in particular to a deep foundation pit going up and down stairs and a telescopic support part and a suspension part for the stairs.
