Subway tunnel segment reinforcing cage overturning machine and overturning method

Abstract

The invention discloses a subway tunnel segment reinforcing cage overturning machine. The subway tunnel segment reinforcing cage overturning machine comprises a traveling unit, a lifting unit and a rotating unit, wherein the traveling unit, the lifting unit and the rotating unit are all installed on a vehicle frame. The traveling unit comprises a first motor and wheels, and driving gears are arranged on rotating shafts of the first motor. Driven gears are fixed to the lateral sides of the wheels. The driving gears are matched with the driven gears during use. The wheels are installed at the bottom of the frame. The lifting unit comprises air cylinders and a lifting frame, wherein the air cylinders are arranged at the top of the vehicle frame. The lifting frame is fixed to and driven by a telescopic rod of one air cylinder to ascend and descend. The rotating unit comprises a rotating frame and a second motor, wherein the second motor is connected with the rotating frame, the rotating shaft is provided with a second bearing, an outer ring of the second bearing is fixed to the bottom of the lifting frame, the rotating frame comprises a connecting body and a clamping part, and the connecting body and the clamping part are fixed together. The subway tunnel segment reinforcing cage overturning machine perfectly solves the problem that a reinforcing cage framework needs to be turned over after being welded, has high overturning efficiency, and greatly prevents a reinforcing cage from being welded off.

Description

technical field [0001] The invention relates to a subway segment steel cage turning machine (or steel cage turning machine). When the force is large, the reinforcement will be desoldered. Background technique [0002] With the rapid development of China's economy, the pace of urban construction is getting faster and faster, and the urban population is relatively increasing, and the travel in the city is also the issue that people are most concerned about. Compared with traditional buses, subways are fast, comfortable, and The advantages of convenience have become the preferred means of transportation for people to travel, which has prompted the rapid development of urban rail transit. [0003] Subway is the most mature technology in rail transit, because it belongs to underground transportation, it will not affect normal vehicle traffic and occupy a lot of land area, and it is vigorously developed by major cities. If you want to build a subway channel, it is unrealistic to...

Problems solved by technology

If you want to build a subway channel, it is not realistic to use on-site pouring, and there are great safety hazards, which cannot guarantee the stability and safety of the channel. Therefore, another way is to use splicing to build the subway The channel, the size of the segment relative to the channel, is enough to splice thousands of segments, so the demand for the subway segment becomes very large

[0004] According to production experience, the production speed and quality of segmented steel cages are excellent with the process of facing upwards. However, when installing the steel cages, the curved surfaces need to face downwards, so the welded steel cages need to be adjusted by other equipment. It is turned over. For the welding workshop of large logarithm reinforcement cages, cranes are used to lift and turn over. However, the turned reinforcement cages are easy to de-solder, resulting in a very large amount of repairs.

At present, there is no equipment on the market for turning the steel cage of the segment, and designing a special equipment for the turning of the steel cage can effectively improve the turning efficiency of the steel cage
