Description
Technical field
The utility model relates to rail welding equipment for after-treatment in a kind of seamless railroad site operation, particularly a kind of equipment that is used for the steel rail weld joint aligning.
Background technology
Change in the construction of shop in newly-built construction of gapless track and old line, need carry out field Welding, simultaneously, also need carry out the scene aligning the welding point that can not satisfy smooth-going requirement to rail.Building-site can adopt conventional portable rail bender (or claiming straight trailer) straightening of kinked rail to perverted joint at present; The lateral rigidity of rail is little, and this portable rail bender can be accomplished the side direction aligning of rail under cold conditions.And the vertical rigidity of rail is very big, needs very big very heavy equipment could accomplish the vertical aligning of rail.The at present on-the-spot methods that adopt thermal straightenings promptly adopt the heating of oxy-acetylene gas butt joint position more, manage to apply a little relatively external force then, perhaps add to support to change its relative shape, let the rail pyroplastic deformation.The advantage of thermal straightening is that equipment is simple, and is simple to operate, but maximum problem is that the aligning result is wayward, the aligning inefficiency.Since the speed raising of railway, the glacing flatness requirement that has improved gapless track, and thermal straightening technology can't satisfy the glacing flatness requirement of site operation.The scene is needed badly and can be made progress and downward aligning to welding point, and the aligning result manifests, is easy to control and transportable equipment immediately.
The utility model content
The purpose of the utility model just provides the vertical straightener of a kind of mobile steel rail welding point; The vertical straightener of this kind can vertically be aligned the steel rail weld joint under the state of cooling at the construction field (site), and the aligning result is easy to control, and aligning efficient is high; And can move, make things convenient for site operation.
The utility model realizes that the technical scheme that its goal of the invention adopted is: the vertical straightener of a kind of mobile steel rail welding point; Its design feature is: an end of crossbeam is fixed with application of force oil cylinder, and the piston rod of application of force oil cylinder bottom links to each other with application of force rail clamping device; Two rail clamping devices that can move along crossbeam also are housed on the crossbeam.
The course of work and the principle of the utility model are:
Straightener is ridden on the rail to be aligned, will be held on the weld seam of rail near the rail clamping device of application of force rail clamping device.According to the bending shape of welding point, move two rail clamping devices to adjust the relative distance of two rail clamping devices and application of force rail clamping device again, make each clamping device clamp rail then along crossbeam.To high joint or low joint is corresponding through application of force oil cylinder and piston rod thereof application of force clamping device is applied straightening force downward or upward; Thereby with the bite of application of force clamping device as the point of application; As the resistance point, the bite of another clamping device utilizes lever principle as fulcrum near the bite of the rail clamping device of application of force rail clamping device; Make rail carry out bending and shear strain, accomplish aligning rail joint.
Aligning unclamps two rail clamping devices and application of force rail clamping device after accomplishing from rail, more whole straightener is contained on the construction flat car, promptly can be moved to next one rail place to be aligned, and aligns next time.
Compared with prior art, the beneficial effect of the utility model is:
One, utilizes lever principle to impose enough straightening force by application of force oil cylinder, can vertically align the steel rail weld joint under the state of cooling at the construction field (site) to rail.Than thermal straightening, its leveling effect directly, be easy to control, efficiency of construction is high.
Two, the application of force oil cylinder application of force, the also application of force that can make progress downwards, thus all can effectively align high joint and low joint; Two rail clamping devices can move along crossbeam, thereby can adjust the relative distance of two rail clamping devices and application of force rail clamping device, also are the adjustable ratio of its force arm and resistance arm, can adapt to the aligning of differently curved form welding point.
Three, after the clamping device of this straightener unloaded from rail, whole straightener can be contained on the construction flat car and move, and makes things convenient for site operation.
The concrete composition of above-mentioned application of force rail clamping device is: be used for two grip blocks of clamping rail, the clamping plate in the two grip blocks outside connect through screw rod; The top of the clamping face that two grip blocks are relative is embedded with T type push rod, and the top of T type push rod is connected with the piston rod thread of application of force oil cylinder.
The application of force rail clamping device of above structure can be crossed grip block and act on the rail jaw, applies active force upwards to rail; T type push rod bottom then acts directly on the rail head of rail, also can apply downward active force to rail, has realized simply and easily rail is applied straightening force up or down.And the clamping plate in the two grip blocks outsides connect through screw rod, and grip block is fastening, the lateral force that produces in the time of can resisting aligning, and convenient construction again, efficient is high.
The concrete composition of above-mentioned rail clamping device is: be used for two grip blocks of clamping rail, the clamping plate in the two grip blocks outside connect through screw rod; The top of the clamping face that two grip blocks are relative is embedded with T type push rod, and the top of T type push rod is entrenched in the link slot with the crossbeam frame, and the crossbeam frame is sleeved on the crossbeam.
The rail clamping device of above structure can be crossed grip block and act on the rail jaw, applies reaction force upwards to rail; T type push rod bottom then acts directly on the rail head of rail, also can apply downward reaction force to rail, has realized resistance point and fulcrum fixing when the rail lever aligned simply and easily.Simultaneously; The top of the T type push rod in two grip blocks is entrenched in the link slot with the crossbeam frame; The crossbeam frame is sleeved on the crossbeam; Two rail clamping devices can be moved along crossbeam easily, thereby convenient force arm and the resistance arm ratio of adjusting when aligning can adapt to differently curved form welding point.And the clamping plate in the two grip blocks outsides connect through screw rod, and grip block is fastening, the lateral force that produces in the time of can resisting aligning, and convenient construction again, efficient is high.
