Abstract
A railway vehicle flexibility factor test tool is provided with two pairs of pits located at the outer side of a steel rail. The distance between the pit center to a center line of the rail is equal to half of a horizontal span of a journal box, the distance between centers of the two pits in pair is equal to a wheel base of a bogie, and the distance of a vehicle is controlled by the distance between the centers of the pits in pair. A cement layer is laid at a pit bottom of each pit, an iron plate is arranged on the cement layer, and a lifting jack is placed on the iron plate and located right below the journal box. The railway vehicle flexibility factor test tool achieves the purpose of measuring vehicle flexibility factor by gradually operating the lifting jack to lift the journal box on one side of the vehicle up to a maximum super-high height and recording the leaning angle of a vehicle body based on the conditions of air supply equipment, protection of a crown block, a flat and straight rail and the like at vehicle general assembly working positions of workshops. The railway vehicle flexibility factor test tool is capable of meeting super-high requirements of rails of different projects, line adjusting back and forth is not needed, test time is shortened, and test cost is saved.
Description
Technical field
The utility model relates to a kind of rail vehicle ratio of slenderness test frock.
Background technology
As shown in Figure 1; The rail vehicle ratio of slenderness is to rest on the circuit that superelevation is h when stationary vehicle; Need be raised to the maximum superelevation of circuit according to standard, the superelevation angle [alpha] that its wheel 2 rolling planes (rail 1 end face) and surface level form is because superelevation; Car body 4 pendulum spring 3 tilt and with form an angle beta perpendicular to the rail level center line, the ratio of beta/alpha is ratio of slenderness.
Ratio of slenderness test at present is the track through one section superelevation h of single pavement, during test, in the workshop, vehicle is filled wind to normal condition at first earlier; Vehicle transferred to walk on the superelevation track make an experiment; Vehicle transfers row to expend the more time, possibly cause in the way and leak out, and need mend wind again; Feasible test need be shunt repeatedly, cost great amount of time and energy.And possibly build different track Ultrahigh Bypass to Projects with Different and satisfy test, make experimentation cost also can increase greatly.
Summary of the invention
The utility model technical matters to be solved is, overcomes the above-mentioned shortcoming of prior art, and a kind of rail vehicle ratio of slenderness test frock is provided.
In order to solve above technical matters; The rail vehicle ratio of slenderness test frock that the utility model provides is characterized in that: have two pairs of melt pits that are positioned at the rail outside, the distance of said melt pit center to track centerline equals the half the of the horizontal span of axle box; The center distance of two melt pits of melt pit equals wheel-base bogie in pairs; The center distance of melt pit is a length between truck centers in pairs, lays cement layer at the bottom of the hole of said melt pit, and iron plate is set on the cement layer; Said iron plate go up to be placed lifting jack, said lifting jack be in axle box under.
Further, said melt pit is apart from rail level degree of depth h
1=h
0-h
Min+ 10mm, wherein, h
0Be lifting jack elemental height, h
MinBe the minimum value of axle box apart from the rail rail level.
Further, be equipped with the adjusting pad plate on the said iron plate, lifting jack is positioned on the adjustment backing plate.
Further, the long 700mm of said melt pit, wide 350mm.
The utility model is based on conditions such as the ventilation apparatus of workshop vehicle general assembly station, overhead traveling crane protection, straight tracks; Through step-by-step operation jack stand vehicle one side shaft case; Until reaching maximum superelevation height, write down the car body side tilt angle, reach the purpose of measuring vehicle ratio of slenderness; This device can satisfy the requirement of disparity items track superelevation, and need not adjust back row, shortens test period, practices thrift experimentation cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is that traditional ratio of slenderness detects synoptic diagram.
Fig. 2 is the melt pit distribution vertical view of this rail vehicle ratio of slenderness test frock.
Fig. 3 is this rail vehicle ratio of slenderness test frock side view.
Embodiment
The rail vehicle ratio of slenderness test frock of present embodiment, like Fig. 2, shown in Figure 3, it has the two pairs of melt pits 5 (the long 700mm of melt pit, wide 350mm) that are positioned at rail 1 outside, the distance h of said melt pit 5 centers to track centerline
3Equal the half the of the horizontal span of axle box, in pairs the center distance h of two melt pits of melt pit
4Equal wheel-base bogie, in pairs the center distance h of melt pit
5Be length between truck centers, lay cement layer 6 at the bottom of the hole of melt pit 5, iron plate 7 is set on the cement layer 6, place adjustment backing plate 8 on the said iron plate 7, place lifting jack 9 on the adjustment backing plate 8, said lifting jack 9 be in axle box 10 under.Melt pit is apart from rail level degree of depth h
1=h
0-h
Min+ 10mm, wherein, h
0Be lifting jack elemental height, h
MinBe the minimum value of axle box apart from the rail rail level.
Melt pit increases the 10mm degree of depth so that lifting jack can be installed on below the axle box smoothly; Tall and big in h for axle box apart from rail level
MinVehicle at the trial, can cooperate with adjustment backing plate quantity to adapt to vehicle and raise requirement.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
