Description

Super-long rail pressure maintaining levelling welding machine

The utility model belongs to a kind of way and structures, particularly a kind of super-long rail pressure maintaining levelling welding machine.

Existing long rail bonding machine has two kinds of structures, and a kind of is four cylinders, four plug structures, and another kind is twin-tub four plug structures.Said four cylinders, four plug structure bonding machine intensity are big but to push away when protruding be protruding toward extrapolation, therefore, are not to carry out under packing state, influence welding quality.Another kind of owing to the two plugs of installation in single cylinder, its complex structure, the fault rate height, maintenance difficulty is big; In addition, its upset intensity does not reach requirement, and weld bond easily misplaces, and causes welding quality undesirable.

The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of make diffuse, upset, welding, remove operation such as knurl connect be used to finish and under packing state, push away protruding, thereby guarantee welding quality and the super-long rail pressure maintaining levelling welding machine that can reduce labor intensity.

The utility model is achieved in that it has one by the upset oil cylinder, oil circuit, upset piston and upset pull bar, the upset end floor beam, the upsetting machine that drift and heater-driven mechanism constitute, it also is equipped with on the upset pull bar and pushes away protruding piston and levelling piston rod, levelling end cross beam and drift are housed on the plunger piston rod, push away protruding oil cylinder and levelling oil cylinder lid, be connected with at the left end of levelling piston rod and push away protruding pulling block, and between levelling piston rod and the levelling end cross beam levelling cross beam copper bush is housed, push away the left side of protruding oil cylinder, right part has one to push away protruding return oil pipe and push away the protruding oil pipe that ejects respectively, right-hand member at levelling oil cylinder lid is equipped with levelling spare nut, and the right-hand member and the levelling spare nut of upset pull bar tighten together, constitute and push away protruding mechanism, this super-long rail pressure maintaining levelling welding machine also has one by the levelling device main body, the top cutter, the levelling device that broadsword and bed plate constitute, on the levelling device main body, be fixed with the broadsword slideway, the broadsword seat slide block that a through hole is arranged in the middle part of being placed with in the broadsword slideway, with the broadsword correspondence position withdrawing handle is being installed on the levelling device main body, the bottom of last withdrawing handle is inserted in the through hole of broadsword seat slide block, with the levelling device main body of last withdrawing handle bottom apex correspondence position on be fixed with back-moving spring, be connected with the broadsword alignment pin on the back-moving spring, constitute retraction mechanism on the broadsword.

According to above-mentioned super-long rail pressure maintaining levelling welding machine, there are two chucking lugs corresponding twin-tub position on the said levelling device main body.

The utility model has the advantages that and when diffusing operation, directly carry out weld job, and under the situation of upset state pressurize, remove knurl, make and diffuse, upset, welding, remove operation such as knurl and connect and be used to finish, alleviated working strength of workers, improved welding quality.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in drawings, the utility model has a upset oil cylinder 16, upset piston 15 and upset pull bar 18, at upset oil cylinder 16 left ends the upset piston is installed and is equipped with mother 14 and upset oil cylinder cover 13, corresponding upset oil cylinder 16 right end position are equipped with upset end floor beam 6 on upset pull bar 18, upset crossbeam copper sheathing 17 is housed therebetween, on upset oil cylinder 16 and upset end floor beam 6, be fixed with by shaking picker bar 2, shake fiery carriage 3, shake fiery swing arm 4, shake the heater-driven mechanism that fiery roller 7 constitutes, left end and upper right quarter at upset oil cylinder 16 have a upset oil return pipe 1 and upset high-pressure oil pipe 5 respectively, right part at upset pull bar 18 is set with levelling piston rod 21, on levelling piston rod 21, be equipped with and push away protruding oil cylinder 20 and levelling end cross beam 9 is housed by levelling cross beam copper bush 19, be useful on the protruding pulling block 8 that pushes away of placing levelling device by being threaded at levelling piston rod 21 left ends, the upper left quarter and the right-hand member that push away protruding oil cylinder 20 have one to push away protruding return oil pipe 10 and eject oil pipe 11 respectively, push away the levelling spare nut 23 that protruding oil cylinder 20 right-hand members are equipped with levelling oil cylinder lid 22 and tighten together with upset pull bar 18 right-hand members, on said upset end floor beam 6 and the levelling end cross beam 9 drift 12 is housed respectively, flange of rail bolt 34 and nut 25 and tread bolt.This soldering apparatus also has a levelling device main body 30, two bale handles 26 and chucking lug 26A are arranged on levelling device 30 main bodys, top blade 29 is installed on levelling device main body 30, broadsword sheet 35 and by shear bar 34, the bed plate that bed plate handle 36 and blade hold-down screw 33 constitute, by hold-down screw 37 broadsword slideway 31 is installed at levelling device main body 30 middle parts, the broadsword seat slide block 27 that a through hole is arranged in the middle part of being placed with on the broadsword slideway 31, at 35 liang of side positions of levelling device main body 30 corresponding broadswords withdrawing handle 28 on the broadsword is installed, the bottom of last withdrawing handle 28 is inserted in the through hole on the broadsword seat slide block 27, withdrawing handle 28 bottom positions have a spring base on correspondence on the levelling device main body 30, back-moving spring 38 is installed in this spring base, on back-moving spring 38, be connected with broadsword alignment pin 32, retraction mechanism on the formation.

When real work, the rail after diffusing is put into upset end floor beam 6 and levelling end cross beam 9, by 5 oilings of upset high-pressure oil pipe, promote upset pitch brace 18 and be moved to the left, upset end floor beam 6 moves right simultaneously.Be accompanied by the powerful pulling force that manually hits rail and this machine, rail breach two sections distance is dwindled gradually, the last close card of two rails section, utilize heater to give the heating of rail two section parts again, when the temperature at rail profile place is raised to the plasticity temperature, improve the hydraulic coupling of this machine, make the free mutually infiltration of metallic molecule at rail profile place, rail two sections are really combined together.Because the effect of this machine upset, can extrude exoncoma in the commissure, levelling device 30 is contained in pushes away on the protruding pulling block 8 again, and move withdrawing handle 28 downwards, slide block 27 pin 32 that is positioned is blocked, carry out upper slitter.The conversion oil circuit pushes away protrudingly, and levelling piston rod 21 is moved to the left, drive levelling device 30 and be moved to the left, the fuel tap conversion is by pushing away protruding return oil pipe 10 oilings, levelling device is moved right, thereby exoncoma is turned down, treat that the temperature of commissure is reduced to below 500 ℃, pull on earlier withdrawing handle 28 forward, handle 28 to equal with levelling device main body 30, is upwards lifted again in alignment pin 32 tops, carry out withdrawing, unload this bonding machine again, all diffuse welding process and finish.
