Problems solved by technology

This is used for transportation lifting equipment for subway construction, which solves the inconvenience of moving the lifting equipment. Lifting the center of gravity of the heavy object will easily cause the equipment to tilt, causing safety hazards to the surrounding personnel and equipment. After the heavy object is lifted, the staff need to pay extra The operation can only be carried out by setting up the bracket, which will affect the construction progress
Although the device can transport the material, the material cannot be stably fixed during the transport process, which is prone to safety accidents

Abstract

A lifting device for subway tunnel construction includes a roller chassis, a square plate mounted on the roller chassis, a lifting assembly mounted on the square plate and performs lifting through power provided by a motor, and a fixing assembly mounted on the lifting assembly and used for fixing materials. Through cooperation of the lifting assembly and the fixing assembly, the materials can be fixed quickly and conveniently and then are quickly conveyed in a lifting mode, and through a third baffle and a second baffle, the left side and the right side of the materials can be limited, so thatthe materials are safer in the conveying process. When the materials are conveyed by equipment, conical-head rods move downwards to be inserted into the ground, and thus the equipment is safer to use.

Description

technical field [0001] The invention relates to a lifting device, in particular to a lifting device for subway tunnel construction. Background technique [0002] Subway is a form of railway transportation, which refers to the urban rail transit system that mainly runs underground, that is, the abbreviation of "underground railway" or "subway". Many of these systems may be turned into ground or elevated road sections outside the city center in order to match the built environment and consider construction and operating costs. The subway is an urban rail transit system that covers various underground and above-ground right-of-way proprietary, high-density, and high-capacity urban rail transit systems. During the construction of subway tunnels, it is necessary to use lifting devices to transport materials to high places. [0003] The patent authorization announcement number is CN209940418U, which discloses a transport lifting device for subway construction, which relates to t...
