The utility model is characterized in that a pressure mechanism is provided with an oil cylinder; a piston rod of the oil cylinder is positioned by a connection plate, and a synchronous back stroke is realized; two eccentric rail base bolts are arranged on a right oblique iron seat, and an oblique iron seat is in a flow welding composite structure; the hydraulic seal of the oil cylinder is in a composite structure. The utility model has the advantages of good processing property, reliable work and light weight of the whole machine.
Description
The utility model is the important facility of the long rail of a kind of welding railroad, particularly a kind of power unit type protruding press-connection machine that pushes away.
The circuit welding procedure of the long rail of railway, its characteristics are frequent mobile operational process, and the rail welding machine tool is by artificial resettlement.Thereby equipment is answered light and flexible, dependable performance.There are the following problems for existing press-connection machine:
1, the wedge seat adopts cast steel more, and adopts the combined sleeve oil cylinder, heavily about 300 kilograms of main frame, and kilogram surplus the pushing convex knife body nearly weighs ten, the coaxial required precision height of not only complex structure, and two cylinders all makes troubles so not only for device fabrication, assembling, maintenance; And because press-connection machine stressed big (45 tons of thrusts), condition of work is abominable, so equipment has often reduced sleeve oil cylinder two cylinders because of the deformation of member again in the weldering rail is constructed coaxial precision easily produces " scuffing of cylinder bore ", influences the normal use of equipment.
2, push away in the convex process in overlap, the cutter hub walking is not steady, can not guarantee the grazing of rail joint.
3, rail upset and push away protruding oil cylinder and all be arranged on the press-connection machine wedge seat and form " combined type " sleeve oil cylinder, with the right side, the sliding friction face of cylinder body and piston is dry friction from the first road sealing ring in the oil cylinder bottom, its friction pair is respectively steel-steel, steel-copper.
4, train wheel rolls on rail and is rail head end face (also claiming wheel tread).Therefore, the location of rail on press-connection machine should be benchmark with the rail surface also.Four flange of rail bolts of former press-connection machine are the equal diameter coaxial bolts and are positioned at same plane, and two rail to be welded are positioned (to be compressed by the tread bolt) on the flange of rail bolt.Owing to the error (about 1.0-1.5mm) of roll out steel rail, thereby cause two rails postwelding rail head not on same plane in the high direction of rail.
The purpose of this utility model is to solve existing existing problem, provides a kind of in light weight, the power unit type protruding press-connection machine that pushes away easy to use.
The utility model is achieved in that by left and right sides wedge seat and two main frames that piston is assembled into, two weldering rail actuator cylinders are loaded on left wedge seat, and the oil cylinder piston bar passes wedge seat hole and right wedge seat is fastening.Wedge and flange of rail screw are separately positioned on the waist and the bottom of wedge seat.
Pushing away protruding mechanism and press-connection machine is split-type structural, and it is made up of pushing convex knife body, joint cover and backing plate.Push away protruding mechanism and have oil cylinder, the oil cylinder piston bar is realized synchronous backhaul with the joint cover location.Under the pressure oil effect, the pushing convex knife body is a backrest with press-connection machine wedge seat, moves forward, and realizes that the rail overlap pushes away protruding.
On the wedge seat of a press-connection machine left side, be furnished with two coaxial flange of rail bolts of equal diameter, be furnished with two eccentric flange of rail bolts on the right wedge seat.Left side wedge seat is realized the location with the end mating surface of its positioning boss and flange of rail bolt.Right wedge seat and flange of rail bolt are to realize by the locking of the eccentric cam on flange of rail bolt rail in the location of circumferencial direction.
The wedge seat adopts the cast welding composite construction, and its main body adopts high-strength cast steel, and top is attached with the top board welding, and wedge seat section is a box-structure.
Oil cylinder comprises cylinder body, piston rod, piston, and sealing ring cooperates to be formed; The hydraulic packing of oil cylinder is a fabricated structure: the outer ring is F
4-bronze composite, inner ring is O shape circle; Match with the piston rod sealing at position of oil cylinder is arranged on oil cylinder microcephaly end.
Advantage of the present utility model is:
1, will push away protruding oil cylinder and be arranged on the cutter hub, and make heavily about 150 kilograms of main frame, cutter hub nearly weighs 40 kilograms, and the two is a split-type structural, and distribution of weight is moderate, and equipment is flexible, is suitable for the on-the-spot construction operation that flows.
2, weight and the contour dimension in order to alleviate the pushing convex knife body directly processes oil cylinder on the cutter hub biside plate, the cutter hub mechanical processing technique is good, the intensity height.Hydraulic packing, the guiding of cutter hub oil cylinder and press-connection machine weldering rail actuator cylinder adopt the minimum F of coefficient of friction
4-bronze composite and O shape circle are used in combination, and use O shape circle to compare more separately, and composite rim intensity height, hardness height, hear resistance and thermal conductivity are good, and extremely wear-resisting, have effectively guaranteed the reliability of oil cylinder work.
3, it pushes away protruding oil cylinder and is located on the cutter hub, compares with the cutter hub of existing press-connection machine, and cutter hub operation self-conductance is good, helps guaranteeing the grazing of rail joint.
4, the weldering tread is forged the place's of being slidingly matched cancellation copper sheathing of oil cylinder and piston rod; Hydraulic packing circle groove moves to right-hand member.Owing to cancelled copper sheathing; improved the proper alignment of oil cylinder and piston, piston rod; in addition, fundamentally stop press-connection machine copper sheathing in the construction and often skidded off the disadvantage (because of the damage of cylinder bottom sealing ring, the oil cylinder hydraulic oil is scurried into the copper sheathing end face and copper sheathing is extruded cylinder body) that cylinder body influence the facility normal operation.O-ring groove moves to right-hand member by the oil cylinder middle part, and its mechanical processing technique is good.Simple in structure, reliable operation, reduce cost.
5, in order to solve the postwelding grazing problem of roll out steel rail rail head end face, then on the wedge seat of a press-connection machine left side, be provided with conventional concentric flange of rail bolt, be provided with eccentric flange of rail bolt on the right wedge seat.Like this, two rails can left wedge seat rail surface be a benchmark promptly in the adjustment of short transverse, adjusts (the tread bolt compresses the location) by the eccentric flange of rail bolt of right wedge seat, and makes the two rails end face be in same plane.
6, the wedge seat structurally adopts based on cast steel, attachedly welds with top board.Like this, wedge seat section is to have the higher box-structure that does bending rigidity, and simple in structure, cost is low, in light weight.
