Abstract
The utility model discloses a railway vehicle load test device. The railway vehicle load test device comprises a pressure sensor, a height-adjustable support device and a load device, wherein the pressure sensor is arranged at a pressure loading point of a vehicle body, the height-adjustable support device is arranged above the pressure sensor, the load device is arranged above the height-adjustable support device, a load is placed on the load device; and the loading pressure required for each point can be achieved by changing the weight of the load and adjusting the height of the height-adjustable support device so as to achieve the test purpose.
Description
Technical field
The utility model relates to the carrier load-carrying to be measured, and is specifically related to a kind of carrier loading test device.
Background technology
In the process of China railways freight transportation, train load there is very strict regulation, no over-loading, it is a requisite job that rolling stock is carried out the load-carrying detection.
The loading test of rolling stock generally is that several stress points on the railroad car are tested, to determine its dead weight capacity, in the loading test of traditional rolling stock, the suitable thing of normal operation counterweight or counterweight separates on-load pressure to each stress point, as shown in Figure 1, 2, choose some pressure-loaded points at four jiaos of car bodies, edge, center, add counterweight or its suitable thing at described pressure-loaded point, judge the dead weight capacity of car body according to the weight of counterweight or its suitable thing, and whether the check car body reaches the load-carrying requirement.
The shortcoming of technique scheme is: when adding loading weight very large (more than hundred tonnes), need separately carry out load test to load(ing) point, and each pressure-loaded point loaded weight is not identical yet in the process of testing; So certainly, quite strict to the dimensional requirement that adds loading (counterweight), because must be to varying in weight that each load(ing) point loads, the position be very compact again again, and the difficulty of test is very large, and unstable.
Therefore be necessary prior art is improved.
The utility model content
For problems of the prior art, the utility model provides a kind of railway vehicle loading test device and method so that when experiment pressure-loaded simple, make experimentation more stable, experimental result is more accurate.
The technical solution adopted in the utility model is:
A kind of railway vehicle loading test device, comprise pressure transducer, height adjustable support and load carrying device, described pressure transducer is contained on the pressure-loaded point of car body, described height adjustable support is installed in described pressure transducer top, described load carrying device is installed in described height adjustable support top, adds loading and is contained on the described load carrying device.
Described pressure transducer is fixed on described height adjustable support bottom.
Described height adjustable support is hydraulic jack.
Described height adjustable support is fixed on the described load carrying device by securing member.
Described load carrying device is provided with block protecting device, prevents from adding the loading landing.
The utility model has the advantage of:
A, add loading and be contained on the load carrying device, for load(ing) point, belong to whole and load, its stability is better;
B, owing to adding loading and be contained on the load carrying device that is provided with block protecting device, therefore the dimensional requirement that adds loading is not needed so strictly, and add loading and easily select, so that test is easy to operate more flexibly.
C, when the loaded weight of each point need to change, as long as total weight that adds loading changes and regulates the height adjustable support, just can reach each point need to loaded weight, reach test objective.
Description of drawings
Fig. 1, Fig. 2 are existing railway vehicle loading test apparatus structure schematic diagram;
Fig. 3 is railway vehicle loading test apparatus structure schematic diagram described in the utility model.
Among the figure, A, B, C are respectively different pressure-loaded points, and 1 is pressure transducer, 2 height adjustable supports, and 3 is load carrying device, and 4 is block protecting device, and 5 is car body.
Embodiment
Further set forth the utility model below in conjunction with the drawings and specific embodiments, be noted that embodiment just does further specific description to technical solutions of the utility model, do not limit protection domain of the present utility model.
As shown in Figure 3, a kind of railway vehicle loading test device, comprise pressure transducer 1, height adjustable support 2 and load carrying device 3, described pressure transducer 1 is contained on the pressure-loaded point of car body 5, described height adjustable support 2 is installed in described pressure transducer 1 top, and described load carrying device 3 is installed in described height adjustable support 2 tops, adds loading and is contained on the described load carrying device 3.
Described pressure transducer 1 is fixed on described height adjustable support 2 bottoms.
Described height adjustable support 2 is hydraulic jack.
Described height adjustable support 2 is fixed on the described load carrying device 3 by securing member.
Described load carrying device 3 is provided with block protecting device 4, prevents from adding the loading landing.
The utility model can also be made a lot of distortion, and those of ordinary skills all should be considered as within protection domain of the present utility model not exceeding the distortion of doing under the utility model spirit and the enlightenment.
