Description

Anticorrosive operation platform truck of pressure steel pipe transportation Technical Field The utility model relates to the technical field of hydropower station pressure steel pipe construction equipment, in particular to a pressure steel pipe transportation anti-corrosion operation trolley. Background At present, the manufacturing scale of the hydropower station pressure steel pipe is large, the pressure steel pipe is formed by splicing a plurality of pipe joints, the length of a single pipe joint is about 3 meters, the weight and the size are large, the number of the single pipe joints are large, the single pipe joint is required to be conveyed into a workshop, and anticorrosion procedures such as surface sand blasting, primer coating, intermediate paint coating, finish coating, cement slurry coating of the outer wall of a buried pipe and the like are sequentially completed in the workshop, and then the assembly is carried out. However, noise, dust and other pollution are easy to generate in the corrosion prevention process, so that workshops must have good sealing performance, and the periphery and the top of the workshops must be sealed. The existing mode of transporting the pipe joint from the outside of the workshop to the inside of the workshop is that the pipe joint is firstly lifted to a traveling trolley horizontally outside the workshop, then the pipe joint is transported to corresponding equipment in the workshop through the traveling trolley, and then the pipe joint is lifted to be in a vertical state for corrosion prevention operation. The prior art patent document with the application number 201720510888.2 discloses an oversized-diameter pressure steel pipe anti-tilting transportation trolley, and specifically discloses a trolley which comprises a main supporting beam, an auxiliary supporting beam, an arc supporting plate, a trolley frame and rollers, wherein the main supporting beam is formed by welding two I-shaped steels in a combined way and is arranged in the middle of the trolley frame, the auxiliary supporting beam is formed by welding I-shaped steels in a combined way and is arranged between the two main supporting beams, the trolley frame is formed by welding two channel steel back-to-back type combinations, the rollers are in contact with transportation rails, the two groups are totally arranged at the front end and the rear end of the trolley frame, the radian supporting plate on the trolley frame is compactly attached to the radian of the outer wall of the oversized-diameter pressure steel pipe, the integral gravity center of the trolley during installation and transportation of the pressure steel pipe is reduced by increasing the weight of the trolley and the contact area with the rails, and the safety risk of the installation and tilting of the oversized-diameter pressure steel pipe is effectively avoided. The oversized-diameter pressure steel pipe anti-falling conveying trolley has the following defects: 1) The pressure steel pipes are horizontally placed and then conveyed into a workshop, and the pressure steel pipes are required to be hung to be in a vertical state, but are influenced by the height of the workshop, and the hanging device is difficult to install, so that the hanging operation in the workshop is quite troublesome; 2) In order to carry out integral corrosion prevention operation on the pressure steel pipe in a workshop, a supporting platform needs to be erected inside and outside the pressure steel pipe, so that each section of the pressure steel pipe is required to be disassembled and erected once, time and labor are consumed, the construction efficiency is affected, and the construction cost is increased.
