Problems solved by technology

[0005] 1) Because it is all manual work, the welding quality is greatly affected by human factors
Unreliable clamping and positioning of rails, difficult to control internal and external quality of welded joints
[0006] 2) Poor equipment stiffness
Because it mainly relies on human work, the design considers that the equipment cannot be made too heavy, and the result of reducing weight is to sacrifice rigidity
Due to the poor rigidity of the equipment, the welding quality is unstable

Embodiment Construction

[0039] Such as figure 1 As shown, a control room, a machine head storage room 3, a generator room 4 and a material room 5 are provided on the flatbed truck 8, and the control room and the machine head storage room 3 are used to store the welding machine head 1, the control cabinet, and the hydraulic pump station and cooling pump station; the effect of generator room 4 is to store the generator, and this generator is a backup, because the rail pressure welding operation does not need a high-power generator set, so railcars can also be used to generate electricity; the effect of material room 5 is to store welding Consumables used (such as grinding wheel, grinder, jack and other auxiliary construction equipment, oxygen cylinders, acetylene cylinders, etc.). The top of the flatbed truck 8 is provided with a boom 2 that can stretch back and forth and swing left and right, and the end of the boom 2 is suspended with a welding head 1 . The front and rear expansion and contraction o...

Abstract

The invention relates to a steel track pressure welding device and relative operation, wherein it comprises a welding head, a control tank, a hydraulic pump and a cooling pump; and it is characterized in that: said control tank, hydraulic pump and cooling pump are arranged on the plate cart; the upper part of plate cart has suspension arm which can move front and back and swing left and right; the welding head is suspended on the end of suspension arm; the fixing end integration, heater support, pusher integration, moving end integration and end plate integration are connected via guide axle on the welding head; the fixing end integration and moving end integration both have steel track clampers; the steel track clampers are connected to the control computer; two sides of fixing end integration and one side of end plate that clamping the steel track have positioning blocks above; the bottom of three positioning blocks are in one horizontal plane. The invention can be used to weld railway, with high quality.

Description

technical field [0001] The invention relates to a rail pneumatic welding equipment, in particular to a rail pneumatic welding equipment composed of a welding head, a control cabinet, a hydraulic pump station and a cooling pump station. The invention also relates to a method of using the rail gas pressure welding equipment. Background technique [0002] At present, the existing rail pressure welding equipment for railways is developed by Jinzhou Research Institute of Shenyang Railway Bureau. The equipment consists of a main engine (crimping machine), hydraulic pump station, cooling pump station, and gas flow control box. After the complete set of equipment and welding consumables (consumables are mainly gas cylinders) are transported to the construction site, the components are assembled on site. The host (crimping machine) is the core component of the air pressure welding equipment, and its host weighs 140-260 kg. During the operation, 4-6 workers lift the crimping machine...
