Description
Technical field
The utility model relates to steel rail flash welding machine fields, in particular to a kind of suspension of steel rail flash welding machine
Formula automatic pressure-maintaining Tui Liu mechanism.
Background technique
Currently, railway traffic, which is substantially all, uses gapless track, and what is used in gapless track major part is all mobile
Flash welder completes the welding of live rail.Its welding line joint quality stablize, have welding quality judge, welding data collecting and
Store function；After the completion of welding, overlap to be cut down at high operating temperatures.Live common mobile flash welder pushes away tumor
Mode is broadly divided into pressure-maintaining tumor pushing and non-pressure-maintaining tumor pushing.
The flash welder of existing non-pressure-maintaining tumor pushing type pushes away tumor device automatically equipped with a set of, does not need manually to hang knife, but
This pushes away tumor device and is only limitted to install and use on non-pressure-maintaining tumor pushing flash welder.Since non-pressure-maintaining tumor pushing flash welder is in welding procedure
On defect and electrode welder wears more serious reason in the welding process, live rail welding is less to use this type
Welding machine.Such as Chinese patent CN201304549Y rail welding machine suspended type tool-setting mechanism, such mechanism is mainly applied in non-pressure maintaining
The flash welder for pushing away tumor type, when pushing away tumor, the clamping cylinder that installation pushes away celectome cabinet unclamps, and upset forging cylinder movement drives peace
Cabinet equipped with Tui Liu mechanism is mobile, and realization pushes away tumor.
Live rail welding largely uses the flash welder of pressure-maintaining tumor pushing type, and pressure-maintaining tumor pushing type flash welder is the same as non-
Pressure-maintaining tumor pushing type flash welder is compared, it can be eliminated due to the influence that tensile stress generates weld seam in rail, and its electrode
It is not easy to wear.The flash welder of existing pressure-maintaining tumor pushing type has a set of pressure-maintaining tumor pushing device.Such as Chinese patent
CN201427222Y pressure-maintaining tumor pushing device.This analogizes tumor device and needs manually push away celectome in advance and hang on rail, abuts against knife
On frame, tumor oil cylinder pushing knife rest is pushed away, and then pushes away the function that celectome completes excision overlap.After the completion of pushing away tumor, manually will also it need
Celectome is pushed away to remove from rail.There are the following problems: (1) artificial extension knife is all random, often occurs pushing away and hurts rail mother
Material and steel rail welding line are except the left and right sides asymmetric phenomenon of overlap reinforcement after tumor；(2) it manually hangs, take knife, labor intensity of workers is big,
Especially manual operation at high operating temperatures, is also easy to damage people；(3) after pushing away the abrasion of celectome cutting edge, celectome cutting edge is pushed away
With the gap of rail, scene can not also be adjusted, can only depot repair.
Summary of the invention
To solve the above problems, the purpose of the utility model is to provide a kind of suspended automatic pressure-maintaining tumor pushing mechanism, it can be real
Knife is now hung automatically, is pushed away tumor automatically, is not required to artificially hang and take knife；The gap of celectome cutting edge and rail is pushed away, scene can also adjust.
The concrete scheme of the utility model is as follows:
A kind of suspended automatic pressure-maintaining tumor pushing mechanism, it is characterised in that: including welding machine cabinet, the welding machine cabinet includes a left side
Cabinet and right case are separately installed with one on each cabinet and push away tumor oil cylinder, push away tumor oil cylinder and be connected with celectome frame is pushed away, described to push away tumor

Spring one end equipped with nut is in hanging state, and the pull rod remains uptrend under spring force,
It thus is avoided that push away celectome device drives with the interference of rail top of steel rail, the welding machine cabinet when clamping, unclamping rail when closing knife
Synchronising (connecting) rod seat up and down, while driving connecting rod up and down and then driving and pushing away celectome device raising and lowering；The drawing
Bar is connected with the top knife for pushing away celectome device top.
The celectome device that pushes away includes left broadsword and right broadsword, the left broadsword and right broadsword by pin shaft respectively with top
Knife is hinged, and the left broadsword and right broadsword are provided with kidney slot, and toolsetting eccentric bushing, the top knife two are equipped in the kidney slot
Side is threaded hole, and the pull rod is mounted on top knife two sides by pin shaft.Cover board is installed on the left broadsword and right broadsword,
The celectome device that pushes away passes through pull rod, hanging on welding machine cabinet, during pushing away tumor, pushes away celectome device, pull rod, bullet
Spring cooperates the stretching for pushing away tumor oil cylinder, retracts and complete to push away tumor automatically under the swing effect of connecting rod.
The tumor oil cylinder that pushes away is connected by extension bar with celectome frame is pushed away.
The synchronising (connecting) rod seat is connected and installed with connecting rod mounting base, and the connecting rod mounting base is hinged with connecting rod.
The connecting rod is connected by hinged block with pull rod upper end.
The celectome device that pushes away is connect by screw with celectome frame is pushed away.
The synchronising (connecting) rod seat can guarantee right case when clamping cylinder stretches out or retracts while around center axis rotation, real
Existing cabinet is synchronous to unclamp or clamps rail, and the synchronising (connecting) rod seat is as the flexible realization of clamping cylinder ramps and declines dynamic
Make.
Further, when left box body and right case intermediate lateral are equipped with clamping cylinder, the synchronous of clamping cylinder connects
Pole socket is hinged by the connecting rod being mounted on left box body and right case.
Further, when left box body and right case center vertical are equipped with clamping cylinder, the synchronous of clamping cylinder connects
Pole socket be directly installed on clamping cylinder piston rod and by connecting rod and left and right cabinet it is hinged.
After adopting the above structure, it pushes away celectome to be suspended on cabinet synchronising (connecting) rod seat by structures such as spring links, and passes through
Kidney slot on left and right broadsword links together with knife rest.When welding, celectome is pushed away with completion when left and right cabinet clamps rail
On rail from dynamic circuit connector knife, when pushing away tumor, push away tumor oil cylinder by extension bar push knife rest and push away celectome device completion push away tumor, weld
After the completion, it is automatic separated on rail with completing when left and right cabinet unclamps rail to push away celectome, pushes away celectome and leaves steel automatically
Rail.In the whole welding process, it pushes away celectome to be suspended on cabinet always, without artificially hanging and taking knife.Push away celectome and steel rail web
Gap can be adjusted by replacing the eccentric bushing being mounted on broadsword；The gap of celectome Yu rail top of steel rail and rail bottom is pushed away, can be passed through
Preloading spring adjusts.
