Abstract

The invention discloses an automatic welding auxiliary device for in-tunnel pressure steel pipe pile joints. The device comprises a trolley group used for bearing two pressure steel pipes subjected to circular seam assembly and driving the two pressure steel pipes to do circular motion, wherein the trolley group comprises two first trolleys and a second trolley; each first trolley is provided with a walking wheel and a rolling driving assembly; and the second trolley is provided with a walking wheel and a rolling driven assembly. According to the device, two sections of pressure steel pipes can be changed into one section of pressure steel pipe, so that although construction procedures are increased, the installation work amount is reduced by half, time and labor cost can be reduced, and good social benefits and economic benefits are generated. Automatic submerged arc welding is used for replacing manual welding, so that weld joints are attractive in appearance, the first-pass yield is improved, and the welding cost is reduced. The automatic welding auxiliary device for the in-tunnel pressure steel pipe pile joints also has the characteristics of low cost, simple manufacturing method, safety and simplicity in use, easy mastering and the like.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to an automatic welding auxiliary device for stacking joints of pressure steel pipes in a cave. Background technique [0002] The pumped storage power station is a hydropower station that uses the electric energy to pump water to the upper reservoir when the power load is low, and then releases water to the lower reservoir to generate electricity during the peak power load period. Also known as energy storage hydropower station. It can transform the excess electric energy when the grid load is low into high-value electric energy during the peak period of the grid. It is also suitable for frequency modulation and phase modulation, stabilizing the cycle and voltage of the power system, and it is suitable for emergency backup. It can also improve thermal power plants in the system and the efficiency of nuclear power plants. [0003] In the prior art, during the const...
