Subway tunnel construction safety supporting device capable of being quickly assembled and extended

Abstract

A subway tunnel construction safety supporting device capable of being rapidly assembled and extending comprises a supporting top frame, a fixing base and a main supporting rod. A left side supportingrod is fixed to one side of the top end of the fixing base, and protection structures are arranged at the two sides of the main supporting rod. According to the subway tunnel construction safety supporting device, fixing grooves are firstly fixed, then fixing blocks are fixed, and multiple sets of limiting stabilizing blocks are arranged at one sides of the interiors of the fixing grooves, so that the limiting stabilizing blocks can vertically slide under the cooperation of fixing sliding rails, and the positions of the fixing blocks are driven to be changed in the sliding process; when the fixing blocks move, the limiting stabilizing blocks at elbows at the bottom ends of the fixing blocks and the limiting stabilizing blocks at different positions can be clamped and fixed, so that the length of the supporting rod at the left side can be changed, the overall extending capacity of the device is improved, the overall flexibility is well improved, and the device can be better applied todifferent environments; and meanwhile, the fixing capacity and the fireproof and explosion-proof effects of the device are also improved.

Description

technical field [0001] The invention relates to the technical field of safety support, in particular to a safety support device for subway tunnel construction that can be quickly assembled and extended. Background technique [0002] With the continuous development of society and the continuous improvement of economic level, people pay more attention to the development of municipal transportation. Therefore, more and more subway tunnels are developed and used. During the construction process, they often face various problems. Among them, the problem caused by support is the most serious, so more and more support devices are used by people; [0003] However, there are still some problems in the use of traditional devices of this type. For example, the internal telescopic extension ability is weak during use, resulting in poor overall practicability. Therefore, in different environments, the overall The applicability of the machine becomes poor, which is likely to cause some t...
