Abstract
The utility model relates to a ball used for a vehicle ball-passing test, with a visible internal sign, characterized by comprising a solid transparent ball body, wherein the surface of the ball body is provided with an external sign, the internal center of the ball body is provided with a metal sign, the ball body is prepared by an impact resistant polycarbonate transparent material, the ball body and the metal sign are integrally moulded through injection moulding technology, and unit codes recorded on the external sign and the metal sign are completely consistent to the sequence numbers of balls used for the test. When the external sign on the surface of the ball can not be identified, the internal sign information can be visually and directly read; when the surface of the ball is abraded and the internal sign information can not be visually read, the metal sign information can be read through an X-ray transilluminator; and when the ball is broken, the metal sign can be found for identification; such that the related information of the ball can be found under any conditions anytime, especially in an accident, thereby tracing back the responsibility of the units using the ball. The ball used for a vehicle ball-passing test can be widely used for various types of railway vehicle braking pipe resistance tests.
Description
Technical field
The utility model relates to a kind of test ball, particularly crosses the ball test ball about a kind of vehicle with visible interior sign for the brake tube for railway vehicle resistance test.
Background technology
It is the first step that motor vehicle braking system carries out the bicycle brake test that vehicle is crossed ball test, and purpose is whether check vehicles brake pipe system is unblocked.During test, test is put into the hose coupling body of vehicle one end with ball, connect single car testing device, under certain compressed-air actuated effect, make test with ball from the air-brake coupling hose of the vehicle one end air-brake coupling hose through brake pipe system and the other end, intactly enter test qualified with being ball test in the ball receiver.
Having the ball test ball now is that a diameter is the solid nylon ball of 25.4mm, and existence wears no resistance, and impact resistance is unstable, and when test scrapped fast shortcoming.Test with ball in braking pipe arrangement because the phenomenon of the breakage of scratching or be hit happens occasionally, namely reach through the test of two, three cars and to scrap limit.In addition, damaged if test is omitted in braking pipe arrangement or in braking pipe arrangement with ball in crossing ball test, in time do not discovered, will cause driving accident.Because existing test only arranges numbering on the ball surface with ball, easily can't identification because of wearing and tearing in the use, therefore do not possess the trackability to applying unit, be difficult to find relevant owner after causing having an accident.The general D class of a railway traffic accident was once arranged, and test is stopped up train pipe with ball and is caused railway freight-car generation brake fault, because test does not have clear and definite sign and can't determine related responsibility person with ball.
Summary of the invention
For the problems referred to above, the purpose of this utility model provides a kind of vehicle with visible interior sign that can review applying unit and crosses the ball test ball.
For achieving the above object, the utility model is taked following technical scheme: a kind of vehicle with visible interior sign is crossed the ball test ball, it is characterized in that: it comprises a solid transparent spheroid, and spherome surface is provided with trappings, and the spheroid inside center is provided with a metal flag.
Above-mentioned spheroid adopts shock resistance type polycarbonate transparent material, with the metal flag integrated injection molding.
The information of said external sign record comprises applying unit code name and test ball serial number, carves and beats at spherome surface.
Above-mentioned metal flag is a sheet metal, carves packing on it and draws together the applying unit code name and test the information of using the ball serial number.
The utility model is owing to taking above technical scheme, it has the following advantages: 1, the utility model is owing to being provided with the sign that can review applying unit in surface and the inside of spheroid, it is hereby ensured to test and to check its flag information with the overall process of ball from bringing into use finally scrapping, realize test is reviewed with the facility of ball.2, the present invention is owing to adopting transparent material to make spheroid, but the user acceptance test during with ball the visual examination test with the consistance of OM outer marker in the ball, simple, intuitive.3, the utility model is owing to arranging metal flag in transparent ball inside, when the spherome surface trappings because of wearing and tearing can't identification the time, can be by the visual interior metal flag information that directly reads, when spherome surface causes internal visual unclear because of friction, can read metal flag information by the X-ray transilluminator, when spheroid is broken, also can find metal flag and carry out identification, whenever it is hereby ensured, can find relevant information when particularly having an accident, realize the Liability Retroact of test with the ball applying unit.4, therefore spheroid of the present utility model is compared with ball with existing nylon test because employing shock resistance type polycarbonate (PC) transparent material is one-body molded by Shooting Technique, has better toughness, wearing quality and stability.The utility model can be widely used in all kinds brake tube for railway vehicle resistance test.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises a solid transparent spheroid 1, and spheroid 1 surface is provided with trappings 2, and spheroid 1 inside center is provided with a metal flag 3.
In above-described embodiment, spheroid 1 can adopt shock resistance type polycarbonate (PC) transparent material, and is one-body molded by Shooting Technique with metal flag 3.
In above-described embodiment, trappings 2 are used for the visual identification of test, and the information of its record comprises applying unit code name and test ball serial number, EC-001 as shown in Figure 1.Trappings 2 can be arranged on spheroid 1 surface by carving the mode of beating.
In above-described embodiment, metal flag 3 can be a sheet metal, carves packing on it and draws together applying unit code name and the test information such as ball serial number.
The applying unit code name that said external sign 2 and metal flag 3 are put down in writing and test are in full accord with the ball serial number.
Cross in the ball test, the information of the utility model trappings record will be recorded in the single car test record sheet, be included into the technology files of this vehicle, to realize that this vehicle is crossed the ball test service test to be reviewed with the whole process of ball.In case test is omitted in the car brakeing piping with ball, can review the owner by the information that reads on the metal flag.
The various embodiments described above only are used for explanation the utility model; wherein the structure of each parts, connected mode etc. all can change to some extent; every equivalents and improvement of carrying out on the basis of technical solutions of the utility model all should do not got rid of outside protection domain of the present utility model.
Claims (3)
