Description
Technical field
The present invention relates to a kind of especially postweld head treatment system and method for steel rail weld joint on the line of steel rail weld joint that is used for.
Background technology
Along with the fast development of China railways gapless track technology, the rail welding quality more and more comes into one's own, and guarantees the rail welding quality, not only helps safety of railway traffic, also helps improving train running speed.Steel rail weld joint is divided into mainly in the factory that field Welding connects first two on the welding point and line.
To welding point after welding treatment in the factory, adopt the production line operation mode, the postwelding rail is moved, to carry out normalizing, aligning and finishing on carriage by positive lighter, straightener and finishing machine.
And for field Welding on the line, owing to rail has been layed on the circuit, so can't carry out after welding treatment according to bond pattern in the factory.Therefore, present stage, railway construction in China unit and worker are engaged in maintenance unit when carrying out the after welding treatment of on-the-spot joint, adopt portable continuous productive process, be after the normalizing operation is finished and locked fastener, follow-up aligning operating personnel moves to this joint and removes fastener and align, and locks fastener finishing after, follow-up profile finishing personnel movement is carried out the profile finishing to this joint, until finishing.The rail track that schematically shows with reference to figure 1 with a plurality of welding points.Welding point postwelding normalizing on the typical existing line, aligning and finishing operational method are: carry out operation along the construction direction shown in the arrow 50, at first normalizing operation group is carried the flame normalizing machine and is carried out normalized treatment at joint A place's butt joint A, carry the flame normalizing machine after normalized treatment finishes and carry out normalized treatment to joint B place's butt joint B, joints such as butt joint C, D, E are handled successively subsequently; Joint A is after normalized treatment, and aligning operation group is carried straightener and carried out straightening processing at joint A place, carries after the straightening processing end and at joint B, C, D, E place these joints is carried out straightening processing successively like the equipment class such as straightener; Behind the joint A aligning, joint finishing operation group is carried the profiling sander and is carried out the finishing processing at joint A place, and similarly, carries profiling sander to joint B, C, D, E place after the finishing processing finishes these joints are carried out the finishing processing successively.This operational method, personnel's equipment need ceaselessly scattered distribution construction in long one section circuit, and personnel amount is big, operating efficiency is low, poor stability.
Because the after welding treatment of steel rail weld joint is subjected to on-the-spot many restrictions on the line at present, for example the normalized treatment scene can't provide enough big power supply and have to adopt the flame normalizing mode, and that the logistics support of this mode requires is high, quality stability is poor, poor stability, equipment are maintainable poor, the labor strength height.In addition, the welding point straightening processing adopts ruler clearance gauge formula measurement and jim crow, track jack, jack type aligning can't guarantee flattening precision on the existing line.And existing equipment does not have reliable aligning mode to the vertical bending of welding point on the line.Line top connection finishing at present handle adopt ruler clearance gauge formula measure and profiling polishing, artificial feeding, manually push, the mode of swing, this mode influencing factors of quality is many, be subjected to that workman's technical level restricts greatly, equipment maintainable poor, precision is low, labor strength is big.In addition, the on-the-spot after welding treatment device that uses all belongs to light equipment, the quality control ability.
And in existing operational method, owing to adopt many groups personnel to carry out different operation operations, the front and back operation is difficult to coordinate mutually, therefore causes the uniformity of the post processing effect of the chain rupture of quality control and each welding point or quality low easily.
Summary of the invention
Be desirable to provide and overcome problem that above-mentioned welding point after welding treatment occurred or the system and method that can improve to some extent to small part the after welding treatment of steel rail weld joint on the existing line.
Therefore, the invention provides a kind of after welding treatment system that is used for steel rail weld joint on the line, it comprises: the postweld head treatment device; Straightener; Calibration devices; Can in described postweld head treatment device, straightener and the calibration devices any be lifted and remain on the loop wheel machine of a position of described welding point top by arm; Be used for that at least one provides the power source of power to described postweld head treatment device, straightener and calibration devices; With the traveling portion that can walk on described rail, wherein this traveling portion has the base that is used to support described postweld head treatment device, straightener, calibration devices, loop wheel machine and this power source.
