Description
Technical field
The utility model relates to the front rust remover of a kind of mobile steel rail flash welding weldering.
Background technology
All rail, before flash welding, all need that the conduction of steel rail web is clamped to position and carry out processing of rust removing, and current rail rust removal method is: manually with angle grinding machine or the rust cleaning of portable emery wheel.Labor strength is high, and inefficiency makes production cost higher; And polishing precision, roughness all can not be guaranteed, and often can damage rail mother metal, affect intensity and the service life of rail.
Utility model content
The purpose of this utility model is just to provide the front rust remover of a kind of mobile steel rail flash welding weldering, and this rust cleaning function, carrying out before flash welding in rail, moves aligning web of the rail rust cleaning position and also it carried out to electric grinding rust cleaning; Rust cleaning efficiency is high, labour intensity is low, reduces welding cost; Derusting is high, and the web of the rail light after rust cleaning is smooth, and the intensity of rail is high, long service life.
To achieve these goals, the technical solution adopted in the utility model is: rust remover before a kind of mobile steel rail flash welding weldering, comprise travel mechanism and derusting mechanism, and it is characterized in that:
The composition of described travel mechanism is:
In the middle of the front end-plate of frame, the bottom of end plate, all have the rectangular channel that width is greater than rail head of rail; The bottom homonymy of front end-plate and end plate is connected with clamping hinge, and the hinge hole at the end of clamping hinge and pinch wheels mount pad middle part is hinged; The bottom mounting clamp bearing up pulley of pinch wheels mount pad;
Two tread road wheels are installed, the rolling surface of tread road wheel and the form fit of top surface of rail between two curb girders of frame; In the screw mandrel groove of frame two curb girder bottoms, be installed with screw mandrel, the screw thread of screw mandrel end coordinates with the screwed hole at upper clamp shaft middle part respectively, and the thread rotary orientation at screw mandrel both ends is contrary, and one end of screw mandrel is connected with handwheel after passing clamp shaft screwed hole; The upper hinge hole on the end of upper clamp shaft and pinch wheels mount pad top is hinged;
The composition of described derusting mechanism is: the top board of frame and vertical connecting axle are hinged, and the lateral pin on connecting axle top and one end of transverse arm are hinged; The other end of transverse arm is fixed on motor mounting rack; On motor mounting rack, be fixed with motor straight down; The output shaft of motor is connected with sized flap wheel or emery wheel, and sized flap wheel or emery wheel are positioned at the side of steel rail web, the form fit of the side profile of sized flap wheel or emery wheel and the arc surface of steel rail web; The lower end of motor mounting rack is provided with the safty shield that covers sized flap wheel or emery wheel.
The course of work of the present utility model and principle are:
The rectangular channel of end plate before and after frame is aimed at and needed rail section, the tread road wheel of rust cleaning to be placed in rail top of steel rail, shake handwheel makes screw mandrel rotation, screw mandrel drives clamp shaft to two side shiftings, clamp shaft promotes pinch wheels mount pad top and laterally rotates around clamping hinge, and the bottom of pinch wheels mount pad and pinch wheels thereof are rotated top to the inside around clamping hinge; Four pinch wheels are adjacent to rail head bottom (rail jaw), and pass through the cooperation of the tread road wheel of tread, and on the vertical plane of rail axis, travel mechanism clamps rail head.
Starter motor makes sized flap wheel (or emery wheel) rotation, horizontal pushing motor installing rack again, make the sized flap wheel (or emery wheel) of rotation draw close all the time the web of the rail, push away, draw motor mounting rack along rail axis direction (longitudinally) simultaneously, make tread road wheel and pinch wheels along rail axis direction reciprocating rolling, the sized flap wheel (or emery wheel) of rotation carries out back and forth polishing rust cleaning on the steel rail web of rust cleaning section.
After the web of the rail polishing of rail rust removal section one side has eliminated rust, disable motor, remove sized flap wheel (or emery wheel); Upwards push away motor mounting rack, transverse arm is rotated up around lateral pin, sized flap wheel (or emery wheel) is upwards raised to and exceeds after tread, more horizontal pushing motor installing rack, makes sized flap wheel (or emery wheel) put the opposite side to rail.Put down motor mounting rack to transverse arm bottom contact frame top board, starter motor, repeats the operation of the preceding paragraph, polishes and has eliminated rust to the web of the rail of rail rust removal section opposite side.
Compared with prior art, the beneficial effects of the utility model are:
One, whole device is clamped on the vertical plane of rail axis by travel mechanism, and can move freely along rail axis, by motor-driven sized flap wheel or emery wheel, the web of the rail is carried out to back and forth polishing rust cleaning again, labour intensity simple, convenient, operation is low, rust cleaning efficiency is high, has greatly lowered the cost of rail welding.
Two, the thickness of sized flap wheel or emery wheel is consistent with the width at the required rust cleaning of web of the rail position, and each rust cleaning stroke all can carry out uniform all standing rust cleaning to whole rust cleaning face; Further improved its rust cleaning efficiency, the height at rust cleaning position is accurately controlled in advance by geometry of machinery size; The rust cleaning surface evenness that motor-driven sized flap wheel or grinder buffing go out is good, highly polished, and the rail head qualification rate polishing is high, reduces original intensity and rigidity that mother metal injures, guaranteed largely rail.
Above-mentioned screw mandrel is provided with limited step at the screw mandrel groove inside line of curb girder.
Like this, make pinch wheels draw close or leave in the process of rail in screw mandrel rotation, screw mandrel can lateral shift, and drawing close or leaving of both sides pinch wheels keeps synchronous, can clamp more reliably sooner or unclamp operation.
The top of above-mentioned motor mounting rack is connected with hand-pushing handle.
Like this, by hand-pushing handle to the pushing away of motor mounting rack and whole device, pulling process is convenient, laborsaving.
The position of the top board of above-mentioned frame below transverse arm has been threaded and highly regulated backing plate.
Highly regulate backing plate can conveniently regulate the height of transverse arm to realize the adjusting of sized flap wheel or emery wheel (rust cleaning) height by preparation, replacing or increase and decrease.
Below in conjunction with accompanying drawing and specific implementation, the utility model is described in further detail.
