Description
Technical field
The utility model belongs to railway engineering car technical field, is specifically related to a kind of lifting rail vehicle for construction of railways.
Background technology
Existing lifting rail vehicle, general structure is the restriction due to draw beam and bogie truck, its supporting leg is set directly at vehicle frame medium position, this setting is because supporting leg longitudinal pitch is too little and supporting gravity is too high, cause often occurring that supporting leg is pressed on rail on one side in the time of lifting work, another side supporting leg departs from rail, gently cause hoisting crane lifting unstable, heavy cause toppling of hoisting crane, there is very large potential safety hazard, and because hoisting moment is little, hoisting capacity is little, it is slow to hang together speed, can not meet the need of market, be therefore necessary to propose to improve.
Utility model content
The technical matters that the utility model solves: a kind of lifting rail vehicle for construction of railways is provided, operation supporting leg is arranged to rear and front end, vehicle frame bottom and is positioned at draw beam bottom, the longitudinal span of operation supporting leg is increased, and the supporting gravity of car load is effectively reduced, expand the hoisting moment of car load, improved the lifting weight of car load, and whole vehicle stability greatly improves.
The technical solution adopted in the utility model: for the lifting rail vehicle of construction of railways, there is vehicle frame, on described vehicle frame, transverse plane left side is provided with driving engine, engine output shaft is connected with three through pump with operation, on vehicle frame, transverse plane right side front end is provided with the accumulator box of supplying with power for illumination, described accumulator box rear end is provided with the hydraulic reservoir being communicated with three through pump with operation, planar central position, vehicle frame upper end erecting crane, described crane arm below is provided with tool box, and on vehicle frame, rear portion, transverse plane right side is provided with hand brake valve; Middle part, described vehicle frame lower end is provided with the diesel fuel tanks to engine oil, vehicle frame lower end is provided with forecarriage and trailing truck and is positioned at diesel fuel tanks both sides, and be equipped with locked cylinder on forecarriage and trailing truck, front and rear part, described vehicle frame lower end is equipped with draw beam and draw beam is positioned at forecarriage and trailing truck outside, operation supporting leg is arranged on draw beam, and hitch is arranged on draw beam endface position; Wherein, described operation with three through pump by hydraulic oil control hoisting crane lifting or fall back, operation supporting leg stretches out or locking or the release of retraction and locked cylinder.
Further, described draw beam and hitch are integral type structure, and described operation supporting leg upper surface is directly fixed on draw beam lower surface.
The utility model is compared with prior art due to supporting leg position is rationally arranged, make its maximum hoisting moment reach 125tm, maximum lifting weight is 25t, longitudinally span increases, load-carrying ability is strong, and supporting gravity is low, and car load operational capability and stability are greatly improved than like product, widen the range of use of Operation Van, there is higher practical value.

Detailed description of the invention
Below in conjunction with accompanying drawing 1-2, a kind of embodiment of the present utility model is described.
For the lifting rail vehicle of construction of railways, there is vehicle frame 1, on described vehicle frame 1, transverse plane left side is provided with driving engine 2, driving engine 2 output shafts are connected with three through pump 4 with operation, on vehicle frame 1, transverse plane right side front end is provided with the accumulator box 15 of supplying with power for illumination, and described accumulator box 15 rear ends are provided with the hydraulic reservoir 3 being communicated with operation three through pump 4, vehicle frame 1 planar central position, upper end erecting crane 5, described hoisting crane 5 arm belows are provided with tool box 6, and on vehicle frame 1, rear portion, transverse plane right side is provided with hand brake valve 7, described vehicle frame 1 middle part, lower end is provided with the diesel fuel tanks 8 to driving engine 2 fuel feeding, vehicle frame 1 lower end is provided with forecarriage 9 and trailing truck 10 and is positioned at diesel fuel tanks 8 both sides, and be equipped with locked cylinder 14 on forecarriage 9 and trailing truck 10, described vehicle frame 1 front and rear part, lower end is equipped with draw beam 11 and draw beam 11 is positioned at forecarriage 9 and trailing truck 10 outsides, operation supporting leg 12 is arranged on draw beam 11, hitch 13 is arranged on draw beam 11 endface position, specifically, described draw beam 11 and hitch 13 are integral type structure, described operation supporting leg 2 upper surfaces are directly fixed on draw beam 11 lower surfaces, increased support span compared with common rail crane-car, reduce support level center of gravity, more be conducive to bring into play the load-carrying ability of crane-car straight rail direction, described operation with three through pump 4 by 5 liftings of hydraulic oil control hoisting crane or fall back, operation supporting leg 12 stretches out or locking or the release of retraction and locked cylinder 14.
The utility model is without certainly walking action edge, for the electrified railway construction of standard gauge, the operation such as speedily carry out rescue work, because operation supporting leg 12 is fixed on draw beam 11 lower ends, the supporting gravity of car load reduces greatly, not only improves stability, and promotes maximum hoisting moment, can reach 125t.m, maximum lifting weight can reach 25t, and the speed of hanging together is 120km/h, can carry out the lifting operation of railway equipment.When use, utilize trailer that the utility model is dragged to job location, stirring hand brake valve 7 stops car load, start the engine 2 is worked operation three through pump 4, under the effect of operation three through pump 4, locked cylinder 14 locks forecarriage 9 and trailing truck 10, and operation supporting leg 12 stretches out and is fitted in orbital plane, and hoisting crane 5 is started working.After end-of-job, locked cylinder 14 is free to rotate to forecarriage 9 and trailing truck 10 releases, and the supporting leg 12 of simultaneously working is retracted and departed from and the contacting of orbital plane, and hand brake valve 7 is alleviated, and again utilizes trailer that the utility model is dragged away.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, and the equivalence of being done with content described in the utility model claim therefore all changes, within all should being included in the utility model claim scope.
