Abstract
The utility model relates to a vehicle body static strength testing device, in particular to a longitudinal compressing and tensile force loading device for vehicle body tests. The longitudinal force loading device comprises a coupler tail frame, a front slave plate base and a rear slave plate base, wherein the front slave plate base and the rear slave plate base are respectively fixed to two ends of the coupler tail frame through positioning bolts. The key technology of the utility model is that a coupler is inlaid in the coupler tail frame and closely attached to the front slave plate base through a coupler tail pin, a positioning support is fixed between the front slave plate base and the rear slave plate base in the coupler tail frame through positioning bolts, and a pressure sensor is installed on the positioning support. The longitudinal force loading device for railway wagon tests has the beneficial effects that one end of the coupler is inlaid in the coupler tail frame and is connected through the coupler tail pin, the structure can fully simulate the connecting method of the coupler, the action principle conforms to the actual situation of the coupler, the center height of the coupler is easy to adjust, the coupler can automatically adjust the longitudinal force loading centers of two ends of the vehicle body during the test, so that the center line of the longitudinal force is in the center of the vehicle body, thereby avoiding the twisting force caused by the situation that the acting forces are not loaded in the same straight line.
Description
Technical field:
The utility model relates to car body test of static strength device, relates in particular to car body test longitudinal compression and tensile force charger.
Background technology:
China's truck body test of static strength longitudinal force charger is many at present can not reflect that hitch longitudinal force affects car body really, when carrying out car body test of static strength, can not read real-time and accurately the numerical value of longitudinal force simultaneously.In order to simulate truly the impact of hitch longitudinal force on car body, during simultaneously by test, longitudinal force numerical value can inform testing crew in real time, therefore, urgently provides a kind of test longitudinal force charger, to meet the test examination demand of car body static strength.
Summary of the invention:
Problem to be solved in the utility model is exactly for above deficiency, to provide a kind of can carry out to car body the test longitudinal force charger of longitudinal test of static strength examination.Its technical scheme is as follows:
It comprises hook tail frame, front draft lug and rear draft lug, and front draft lug and rear draft lug are fixed on respectively the two ends of hook tail frame by bolt.Its gordian technique is in hook tail frame, to be close to front draft lug to inlay hitch by coupler yoke key, passes through bolt stationary positioned bearing, setting pressure sensor on positioning support in hook tail frame between front draft lug and rear draft lug.
Compared with prior art, the utlity model has following beneficial effect:
1, the utility model hitch one end is embedded in hook tail frame and adopts coupler yoke key to connect, such structure can fully be simulated the connected mode of hitch, its action principle meets the actual conditions of hitch, be easy to regulate height of coupler centre, when testing, this hitch can automatically be adjusted car body two ends longitudinal forces and load center, make longitudinal force center line in car body in the heart, avoid the twisting resistance not causing at same straight line owing to loading acting force.This hitch can coordinate with existing test effectively, avoids the change of test tool, provides cost savings.
2, the utility model device middle part is provided with pressure transducer, this pressure transducer suffered power when carrying out longitudinal force tension and compression load test is pressure, can reflect in real time the actual conditions of car body when being subject to longitudinal force, longitudinal force be observed more direct, rapid, accurate.
3, below positioning support, be encased inside cushion block, form adjustable positioning support, at the trial, can adjust according to actual conditions height and the fore-and-aft distance of pressure transducer, to guarantee that pressure transducer center and longitudinal force load center on same straight line.Positioning support below is provided with bolt simultaneously, to guarantee to guarantee that positioning support does not rock when longitudinal force charger is installed, guarantees that pressure transducer center and hitch center are on same straight line.
4, front draft lug is placed in hook tail frame and hitch junction, and wherein front draft lug top is provided with bolt, to guarantee to guarantee that front draft lug does not rock when longitudinal force charger is installed, guarantees that front draft lug center and hitch center are on same straight line.
5, rear draft lug is placed in hook tail frame afterbody, and wherein rear draft lug top is provided with bolt, to guarantee to guarantee that rear draft lug does not rock when longitudinal force charger is installed, guarantees that rear draft lug center and hitch center are on same straight line.
6, the utility model is simple in structure, compact, and reliability and durability, can conveniently to car body, carry out longitudinal loading of test of static strength, conveniently reads longitudinal force numerical value.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 vertical view;
Fig. 3 is the utility model perspective view.
Embodiment:
Referring to Fig. 1-Fig. 3, the utility model comprises hook tail frame 5, front draft lug 1 and rear draft lug 4, and front draft lug 1 and rear draft lug 4 are fixed on respectively the two ends of hook tail frame 5 by bolt.Its gordian technique is in hook tail frame 5, to be close to front draft lug 1 to inlay hitch 3 by coupler yoke key 6, passes through bolt stationary positioned bearing 2, setting pressure sensor 8 on positioning support 2 in hook tail frame 5 between front draft lug 1 and rear draft lug 4.
Gap between rear draft lug 4 and pressure transducer 8 is put into and is adjusted backing plate 7.
Below positioning support 2, be encased inside cushion block and form adjustable positioning support.
When car body carries out static strength tension test loading, testing equipment passes to hitch 3 longitudinal forces by actuator, hitch 3 drives hook tail frame 5 outwards to move by coupler yoke key 6, thereby front draft lug 1 is contacted with slave plate before car body, now pressure transducer 8 will show numerical value, and this numerical value is stretching longitudinal force numerical value.
When car body carries out compression test loading, testing equipment passes to hitch 3 longitudinal forces by actuator, hitch 3 drives hook tail frame 5 to move inward by coupler yoke key 6, thereby rear draft lug 4 is contacted with slave plate after car body, now pressure transducer will show numerical value, and pressure transducer shows compression longitudinal force numerical value.
