Abstract
The utility model provides a wheel distance measuring device with changeable wheel distances. The wheel distance measuring device with the changeable wheel distances is a device used for measuring and locating wheel distances of a rail wheel set when a rolling test table adjusts rail distances of test vehicles. Two rail wheels of the rail wheel set is adopted by the test table to simulate two steel rails, and the wheel distances of the rail wheel set are required to change according to changes of the various wheel distances. Accordingly, distance between two wheels of the rail wheel set is required to be adjustable, and distance size is also required to be accurate.
Description
Technical field
The utility model patent relates to a kind of testing table with the right wheelspan measurement mechanism of changeable wheel track rail wheel.
Background technology
The testing table rail wheel is to being to simulate rail, and varied rail wheel that just requires of gauge also wants corresponding adjustable to wheelspan, and size is wanted accurately.Adjustment places this device between the right two-wheeled inboard of variable rail gauge rail wheel during wheelspan, with the wheel medial surface that is connected with the axletree interference fit as positioning reference; Sounding rod one end measuring head pushes against the wheel alignment reference field, with the other end movably the wheel medial surface other end measuring head that pushes against this device get final product.Distance between the two-wheeled is guaranteed by the length of sounding rod itself.At present, method commonly used be with the wheel medial surface that is connected with the axletree interference fit as positioning reference, during the adjustment wheelspan, hand sounding rod, make the one of which end push against the wheel alignment reference field, measure the movably distance between the wheel medial surface of the other end.Four weak points are arranged like this: the one, connecting between removable wheel and the axletree wants reliable, with transfer larger torque and tangential force, need spend the long period, and hand-held for a long time sounding rod easy shaking; The 2nd, the wheel medial surface is bigger, and is parallel in order to ensure two wheels, often will survey 3 positions; The 3rd, influence join operation between removable wheel and the axletree; The 4th, dependence personnel's experience.
Summary of the invention
In order to adjust the changeable wheel track rail wheel fast, accurately, easily to the distance between the two-wheeled; The utility model patent provide a kind of easy, efficiently, measurement mechanism accurately; It can effectively overcome the shortcoming of traditional measurement method, has improved the efficient of rail wheel to the adjustment of two wheel location greatly.
With the variation of test vehicle gauge, the right wheelspan of testing table rail wheel will change thereupon, and the wheelspan dimensional requirement is strict, and each wheelspan adjustment all will be for a long time.Adopt this wheelspan measurement mechanism can effectively overcome the shortcoming of classic method, improve the precision and the work efficiency of position adjustment greatly.
The utility model patent solves the technical scheme that its technical matters adopted: 1. three sounding rods will guarantee that length is identical in margin tolerance; 2. sounding rod is pressed the wheelspan different grouping; Sounding rod be connected with measurement bay, convenient disassembly; Measurement bay be connected with axletree, convenient disassembly.Two measurement bays on axletree, connect into an assembly through screw by two semi-ring stent support separately; Three sounding rods place respectively in the groove of three sway braces of measurement bay, can pass through screw lock.Method of application: earlier two measurement bays are embraced on axletree, the semi-ring lock-screw connects, but does not lock; Then three sounding rods are placed in the groove of three sway braces, push against fixation side wheel medial surface up to sounding rod one end and just lock sounding rod; Pass through two semi-rings of screw lock measurement bay again; Move movably wheel of the other end at last, make its medial surface push against the other end of sounding rod, this wheel and axletree locking are got final product.
The beneficial effect of the utility model is: 1, improved work efficiency greatly: patent of the present invention can guarantee that the changeable wheel track rail wheel once accurately adjusts to the right place to wheel position; 2, easy to use: this device is light, reliable, uses simple to operate; 3, improved the adjustment precision greatly: the precision of wheelspan is guaranteed by sounding rod length dimension precision fully.
Description of drawings
Accompanying drawing is the synoptic diagram of patent of the present invention.
In the accompanying drawing: 1. the right axletree of changeable wheel track rail wheel, 2. measurement bay, 3. screw, 4. sounding rod, 5. screw.
Embodiment
Shown in accompanying drawing, two measurement bays on axletree, connect into an assembly through 4 screws by two semi-ring stent support separately; Three sounding rods place respectively in the groove of three sway braces of measurement bay, again separately through 2 * 2 screw lock sounding rods.
During the adjustment wheelspan: earlier two measurement bays are embraced on axletree, 4 lock-screws of semi-ring connect two semi-rings, but do not lock; Then three sounding rods are placed in the groove of three sway braces of measurement bay, push against fixation side wheel medial surface up to sounding rod one end and just lock sounding rod; Pass through two semi-rings of 4 screw lock measurement bays again; Move movably wheel of the other end at last, make its medial surface push against the other end of sounding rod, this wheel and axletree locking are got final product.
Claims (1)
1. the wheelspan measurement mechanism of a changeable wheel track, it is characterized in that: two measurement bays of this device on axletree, connect into an assembly through screw by two semi-ring stent support separately; Three sounding rods place respectively in the groove of three sway braces of measurement bay, can pass through screw lock.
