Abstract
Provided is a wheel rim thickness caliper of railway wagons and belongs to the technical field of wheel detection of railway wagons. The wheel rim thickness caliper comprises a coupler height difference measuring ruler, a locking position measuring ruler, a wheel rim thickness ruler tips, and a tread ruler tip. One end of the locking position measuring ruler is connected with the coupler height difference measuring ruler perpendicular to the locking position measuring ruler, while the other end of the locking position measuring ruler is connected with a rectangular block body perpendicular to the locking position measuring ruler. The bottom of the inner side of the rectangular block body is equipped with the acute-angle wheel rim thickness ruler tips pointing to the coupler height difference measuring ruler. The outer side of the bottom of the rectangular block body is equipped with the downward acute-angle tread ruler tip. The wheel rim thickness caliper resolves problems of inaccurate detection and low work efficiency when an on-site railway wagon inspector measures the circumference abrasion of the wheel treads of the railway wagons, and has characteristics of easy operation and saving time and labor. In addition, the wheel rim thickness caliper is capable of measuring coupler height difference between couplers and locking position limitation of 16-type train couplers and 17-type train couplers.
Description
Technical field
The utility model belongs to the technical field of railway freight-car wheel detection, specifically a kind of railway freight-car flange thickness slide calliper rule.
Background technology
The goods train thickness of wheel rim that is in operation produces abrasion, at present use the 4th kind of detector for the measurement of wheel rim limit of wear, because the 4th kind of detector belongs to precise engineering surveying utensil and volume and is not easy to greatly the operating personnel and carries, and carries by the section chief of teams and groups.The site work personnel are determined by the personal experience the judgement of wheel rim abrasion situation, often occur fault is judged that inaccurate situation occurs.And when finding that doubtful thickness of wheel rim transfinites, 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 work efficiency lower.
Summary of the invention
The utility model is for the inefficiency that solves on-the-spot train-examiner and exist in wheel rim abrasion situation is judged and judge inaccurate problem, provides a kind of and can increase work efficiency and easy and simple to handle, railway freight-car flange thickness slide calliper rule accurately.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of railway freight-car flange thickness slide calliper rule, comprise the poor survey chi of mutual hook, locking position survey chi, flange thickness chi point and tread chi point, the locking position is surveyed chi one end and is connected with the poor survey chi of perpendicular mutual hook, the other end is connected with perpendicular rectangle block, the inside lower end of rectangle block is provided with the flange thickness chi point of the acute angle shape that points to the poor survey chi of mutual hook, and bottom outside is provided with the tread chi point of downward acute angle shape.
The poor survey chi of hook is rectangle mutually, its long L
1Be 75 millimeters, wide B
1Be 20 millimeters, the long L of chi is surveyed in the locking position
2Be 100 millimeters, wide B
2It is 15 millimeters.Vertical range L between flange thickness chi point and the mutual poor survey chi of the hook inboard
3Be 23 millimeters, the vertical range L between tread chi point and the mutual poor survey chi of the hook inboard
4It is 70 millimeters.Tread chi point is to the vertical range L of rectangle block bottom
5Be 12 millimeters, tread chi point is to the vertical range L of the external side of rectangular blocks
6It is 10 millimeters.
Use of the present utility model: the poor survey chi of mutual hook is close to the wheel inboard, and along the inboard slide calliper rule that promote of wheel, when tread chi point contact wheel tread, and flange thickness chi point is when gapped with wheel rim, and these thickness of wheel rim abrasion are transfinites.If flange thickness chi point contacts with wheel rim, but tread chi point does not contact tread, then this place's flange thickness is no more than the utilization limit.
The beneficial effects of the utility model are that simple to operate, time saving and energy saving, high efficiency have improved wheel rim abrasion situation Accuracy of Judgement, can measure poor and 16, the 17 type hitch locking position limits of the mutual hook of hitch simultaneously.

Embodiment
As shown in Figure 1, the utility model comprises the poor survey chi 1 of mutual hook, locking position survey chi 2, flange thickness chi point 3 and tread chi point 4, the locking position is surveyed chi 2 one ends and is connected with the poor survey chi 1 of perpendicular mutual hook, the other end is connected with perpendicular rectangle block, the inside lower end of rectangle block is provided with the flange thickness chi point 3 of the acute angle shape that points to the poor survey chi 1 of mutual hook, and bottom outside is provided with the tread chi point 4 of downward acute angle shape.
As shown in Figure 2, the course of work of the present utility model: when whether the measurement thickness of wheel rim transfinites, the poor survey chi 1 of mutual hook is close to the wheel inboard, along the inboard slide calliper rule that promote of wheel, when tread chi point 4 contact wheel treads, and when flange thickness chi point 3 was gapped with wheel rim, these thickness of wheel rim abrasion are transfinited.If flange thickness chi point 3 contacts with wheel rim, but tread chi point 4 does not contact tread, then this place's flange thickness is no more than the utilization limit.
As shown in Figure 3, additional function 2 is surveyed chi 2 levels with the locking position and is inserted in 16 types (or 17 types) hook tongue and the gib head, and from top to bottom if insertion, this hitch locking position is transfinites.
