Abstract
A wheel pair failure rescue vehicle for railway vehicle comprises four road wheel assemblies and two carrying beam assembly connection shafts. Each road wheel assembly comprises a wheel and a hollow wheel shaft which is equipped in the wheel through a bearing. Two ends of the wheel shaft extend out from the end surfaces of the wheel and are provided with annular channel sections. Each carrying beam assembly comprises an inner side beam and an outer side beam. Two ends of each side beam are provided with hooks which are matched with the annular channel sections. A wheel supporting holder is provided between the inner side beam and the outer side beam. Two ends of the shaft of the supporting holder are mounted through a mode of penetrating the inner side beam and the outer side beam. The cross sections of the inner side beam and the outer side beam are respectively H-shaped. Two end diameters of the connection shafts are matched with the inner chamber of the hollow wheel shafts. The wheel pair failure rescue vehicle for railway vehicle has the following advantages: small weight, greatly improved operation efficiency. A plug-in type structure can be adopted for the connection shafts. Field mounting process can be further simplified. Compared with an original form of bolt connection, the mounting speed of the wheel pair failure rescue vehicle can be further increased.
Description
Technical field
The utility model relates to the technical field of railway locomotive emergency handling, particularly relates to a kind of railway vehicle wheel to the fault rescue car.
Background technology
Railway locomotive, vehicle are in operation; Faults such as running part (steering framing wheel to) is killed as shelled tread, bearing burnt, gear take place, the inefficacy of gear case suspension gear; Cause certain to take turns and to implement traction not rotating; And the fault wheel can cause the badly damaged of track to can't freely rotating if slide by force in orbit.Bus attendant often can't must be rescued by oneself in request, carries out scene rush to repair by breakdown gang.But, therefore can cause the paralysis of whole service circuit because the restriction of factors such as place, equipment, time usually can not be keeped in repair according to normal maintenance technology the locomotive, the travelled by vehicle portion fault that are occurred.
When this accident occurring; Need as early as possible accident to be handled; Make the fault vehicle leave the scene as early as possible, recovering normal transport as early as possible, thereby keep the unimpeded of whole railway line; Therefore need a kind of can the wheel carrying out emergency relief, make the fault vehicle can in time leave the device of fault in-situ locomotive failure.
The utility model content
The purpose of the utility model is in order to address the above problem, to provide a kind of railway vehicle wheel simple in structure, easy to use to the fault rescue car.
The technical scheme of the utility model is: a kind of railway vehicle wheel is to the fault rescue car; Contain four road wheel assemblies, two carrier bar assembly adapter shafts; Described road wheel assembly comprises wheel and through the hollow axle of bearing installation in wheel, the two ends of this wheel shaft are stretched out the end face of wheel and are provided with annular slot; Described carrier bar assembly comprises inside and outside two side bars; The two ends of two side bars are provided with the hook with above-mentioned annular slot coupling; Be provided with the wheel supporting bracket between the inside and outside side bar, the axle two ends of this supporting bracket pass inside and outside side bar and install, and the cross-sectional plane of described inside and outside side bar is " worker " font; The internal cavities coupling of described adapter shaft two ends diameter and described hollow axle.
Be arranged with the annular hub steady ring on the described adapter shaft.
Described wheel supporting bracket is subtriangular, and its underpart is that casing pipe sleeve is contained on its axle, and top is the arc bearing surface that matees with the wheel radius of curvature.
Described axle interior partly is provided with step surface near outer side bar, and the two ends of described adapter shaft also are provided with the step surface of coupling.
The end of described adapter shaft is provided with internal thread hole, and is equipped with tie bolt and packing ring.
The beneficial effect of the utility model
This railway vehicle wheel is to the fault rescue car; Through changing the cross section structure of inside and outside side bar, can farthest alleviate the deadweight of inside and outside side bar, thereby can make this cover Emergency Tool can the fast speed installation in position; Deal with problems, can significantly increase work efficiency.
This railway vehicle wheel can adopt plug in construction to the adapter shaft of fault rescue car, has further simplified field erected program, compares original bolted form, can further improve installation rate.
