Abstract
The utility model belongs to the technical field of wheel detection of railway wagons and specifically relates to a caliper used for measuring circumference abrasion depth of the wheel treads of railway wagons. The caliper comprises a wheel rim thickness measuring ruler, a locking position measuring ruler, and a tread ruler tip. The inner side of the locking position measuring ruler is a contact surface of the top of a wheel rim. One end of the locking position measuring ruler is connected with wheel rim thickness measuring ruler perpendicular to the locking position measuring ruler, while the other end of the locking position measuring ruler is perpendicularly connected with the tread ruler tip. The bottom of the tread ruler tip is in an acute angle shape. The integral caliper is in an inverted concave shape. The caliper resolves problems of low work efficiency and inaccurate detection when an on-site railway wagon inspector measures the circumference abrasion of the wheel treads of the railway wagons. The caliper used for measuring circumference abrasion depth of the wheel tread of railway wagons has beneficial effects of resolving problems of low work efficiency and inaccurate detection when an on-site railway wagon inspector measures the circumference abrasion of the wheel treads of the railway wagons, a reasonable structure, ingenious appearance, easy operation, and increasing accuracy and work efficiency of measurement of the circumference abrasion of the wheel tread for the inspector.
Description
Technical field
The utility model belongs to the technical field of railway freight-car wheel detection, is specifically related to a kind of railway freight-car wheel tread circular wear depth gage.
Background technology
Be in operation wheel tread and rail Long Term Contact or produce with brake shoe when braking of goods train rubs, and tread can produce abrasion.At present, the Railway Site train-examiner generally uses the 4th kind of detector to the measurement of this hollow on worn tread limit.Because the 4th kind of detector belongs to the precise engineering surveying utensil, expensive and volume is not easy to greatly the operating personnel and carries, and carries by the section chief of teams and groups.Can only judge by rule of thumb during site work personnel inspection hollow on worn tread that easily misjudgment was released the limit vehicle and operation hides some dangers for to vehicle safety.
In addition, when finding that doubtful wheel circumference abrasion are transfinited, use the 4th kind of detector to measure by the section chief of teams and groups, now goods train marshalling is take 102 ten thousand tons of trains as main, strengthened section chief's labour intensity in the middle of invisible, causes inefficiency.
Summary of the invention
The utility model provides a kind of railway freight-car wheel tread circular wear depth gage in order to solve on-the-spot train-examiner to the inefficiency that exists in the judgement of wheel tread circular wear situation and the problems such as judgement is inaccurate.
The utility model adopts following technical scheme to realize:
A kind of railway freight-car wheel tread circular wear depth gage, comprise that wheel rim thickness is surveyed chi, chi and tread chi point are surveyed in the locking position, the inboard that chi is surveyed in described locking position is wheel rim summit surface of contact, the end that chi is surveyed in the locking position is connected with perpendicular wheel rim thickness survey chi, the other end and tread chi vertical connection of point, the bottom of tread chi point is acute angle shape, and the global shape of slide calliper rule is inverted concave.
It is rectangle that wheel rim thickness is surveyed chi, its length L
1Be 78 millimeters, wide L
2It is 20 millimeters.
It is 132 millimeters that the long L of chi is surveyed in the locking position.
Tread chi point is surveyed the distance L of chi inboard apart from wheel rim thickness
4Be 70 millimeters, survey the distance L of chi bottom surface apart from wheel rim thickness
3It is 23 millimeters.
There is a slotted eye junction of surveying chi and locking position survey chi at wheel rim thickness.
Railway freight-car wheel tread circumference wearing and tearing slide calliper rule, just wheel inboard and vertical with axle centerline is close in wheel rim thickness survey chi inboard, along the inboard slide calliper rule that promote of wheel, when wheel rim summit surface of contact contact wheel rim, when tread chi point was gapped with tread, these wheel tread circumference wearing and tearing are transfinited.If tread chi point all contacts with the wheel rim summit with tread, wheel rim summit or tread chi point contact tread, but wheel rim summit and wheel rim are gapped, then this place's tread circular wear does not transfinite.
Additional function 1: wheel rim thickness is surveyed the chi inboard be close to wheel inboard and vertical with axle centerline, along the inboard slide calliper rule that promote of wheel, when tread chi point contact wheel tread, check that wheel rim surveys the chi tail end and whether exceed the wheel rim inside edge, exceed and can be judged to be wheel rim thickness and transfinite.
Additional function 2: the chi level is surveyed in the locking position insert in 13A, 13B type hook tongue and the gib head, if insert, this hitch locking position is transfinites.
The utlity model has following beneficial effect:
Detect accurate, rational in infrastructure, outward appearance is light and handy, easy to operate, time saving and energy saving, improved the train-examiner to wheel tread circular wear situation accuracy of judgement degree and work efficiency.
Description of drawings

Fig. 2 is use figure of the present utility model.
Fig. 3 is the use figure of the utility model additional function 1.
Fig. 4 is the use figure of the utility model additional function 2.
Among the figure: 1-wheel rim thickness is surveyed chi, and chi is surveyed in 2-locking position, 3-wheel rim summit surface of contact,
4-tread chi point, it is long that chi is surveyed in L-locking position, L
1It is long that-flange thickness is surveyed chi, L
2It is wide that-flange thickness is surveyed chi, L
3-tread chi point is apart from the distance of wheel rim thickness survey chi bottom surface, L
4-tread chi point is surveyed the distance of chi inboard apart from wheel rim thickness.
Embodiment
By reference to the accompanying drawings embodiment of the present utility model is described further.
When whether measurement wheel tread circular wear transfinites, wheel rim is surveyed chi 1 be close to the wheel inboard, along the inboard slide calliper rule that promote of wheel, when wheel rim surface of contact 3 contact wheel rims, and tread chi point 4 contacts with tread or when gapped, this wheel tread circular wear degree of depth is and transfinites.(such as Fig. 2)
Additional function 1: circular wear is surveyed chi place on the wheel, when tread chi point 4 contact wheel tread, check that wheel rim surveys chi 1 tail end and whether exceed the wheel rim inside edge, exceed and to be judged to be wheel rim thickness and to transfinite.(such as Fig. 3)
Additional function 2: chi 2 levels are surveyed in the locking position insert in 13A, 13B type hook tongue and the gib head, from top to bottom if insertion, this hitch locking position is transfinites.(such as Fig. 4)
