Embodiment 1

[0024] refer to Figure 1-3 , a subway construction safety protection device, comprising a base plate 1, both sides of the top outer wall of the base plate 1 are fixed with electric telescopic rods 3 by bolts, and one end of the extension rod of the electric telescopic rods 3 is fixed with the same fixing groove 17 by bolts, the fixing grooves The inner wall of the bottom of 17 is fixed with a plurality of piston barrels 18 by bolts, the inner wall of the piston barrel 18 is plugged with the piston rod 10, and the end of the piston rod 10 near the piston barrel 18 is clamped with a piston cylinder, and the outer wall of the piston cylinder is provided with a piston cylinder. A plurality of throttle holes, the piston rod 10 and the piston barrel 18 form a cavity, the top outer wall of the piston rod 10 is fixed with the same support plate 7 by bolts, and the outer circumferential wall of the piston barrel 18 is sleeved with a shock absorbing spring 9 , the outer walls on both s...

Embodiment 2

[0029] refer to Figure 4 , a safety protection device for subway construction. Compared with Embodiment 1, this embodiment has two fixing boxes 23 fixed on the top outer wall of the base plate 1 by bolts, and a storage battery 24 is clamped on the bottom inner wall of the fixing box 23, and the base plate 1 All around outer wall is bonded with annular rubber pad 25.

[0030] During use, the device is equipped with a storage battery 24, which can be used as a power supply for the device to facilitate the use of the device, and the device is provided with an annular rubber pad 25 to play a shock-absorbing and buffering effect.

Abstract

The invention discloses a safety protection device for subway construction. Aiming at the problem that workers are prone to toppling due to poor stability, the following scheme is provided. The safetyprotection device comprises a bottom plate, wherein electric telescopic rods are fixed to the two sides of the outer wall of the top of the bottom plate through bolts correspondingly, and one of theends of extension rods of the electric telescopic rods is fixedly provided with the same fixing groove through a bolt; a plurality of piston cylinders are fixed to the inner wall of the bottom of thefixing groove through bolts, piston rods are inserted into the inner walls of the piston cylinders, and piston cylinders are clamped to the ends, close to the piston cylinders, of the piston rods; anda plurality of throttling holes are formed in the outer walls of the piston cylinders, and cavities are formed in the piston rods and the piston cylinders. According to the safety protection device,the gravity center of the workers is lowered, so that the workers are more stable, the two sides are pulled by adjusting springs, when the workers fall to one side, the other side plays a traction role, the two sides offset each other, and the workers can conveniently and quickly return to the center; and vacuum suction cups are further arranged on the two sides for adsorption, and the situation that the workers topple due to instability is avoided.

Description

technical field [0001] The invention relates to the technical field of protection devices, in particular to a safety protection device for subway construction. Background technique [0002] The subway is an urban rail transit system that covers all kinds of underground and above-ground right-of-way exclusive, high-density, and high-capacity urban rail transit systems in urban areas. The trains run on fully enclosed lines. The other lines are generally located on viaducts or on the ground, and the inner tunnel needs to be maintained during the construction of the subway, so safety protection devices are required. [0003] Most of the existing patents for subway construction safety protection devices on the market have the following deficiencies: workers are easily affected and toppled when they are active, and the stability of the device is relatively poor, and the existing patents are not easy to solve this type of problem. Therefore, there is an urgent need for a A kind of...
