Abstract
The utility model provides a hand brake assembly pulling force test tool, comprising an underframe, a brake chain, a chain wheel, and a pull dynamometer. Installation seats are respectively arranged at the two ends of the underframe. One end of the pull dynamometer is hinged to the underframe while the other end of the pull dynamometer is connected with the brake chain. The chain wheel is rotatably connected on the underframe and located at one side of the pull dynamometer. The brake chain is wound around the chain wheel. By virtue of arranging the two installation seats on the underframe and utilizing the two installation seats to fixedly install a hand brake assembly in a transversely laid manner, the height of an installation gravity center is effectively lowered, the side overturning phenomena are reduced, and the safety is increased; and in addition, a pull force output by the hand brake assembly can be transmitted to the pull dynamometer through the brake chain so that the pull force output by the hand brake assembly can be measured more conveniently, the hand brake assembly pulling force test tool can be used to realize a pull force test of the hand brake assembly conveniently, and the test safety is increased.
Description
Technical field
The utility model relates to tensile test equipment, relates in particular to a kind of hand braking composition tensile test frock.
Background technology
At present, railway locomotive is the vehicles commonly used in people's daily life, and hand braking composition is used for locomotive is carried out hand brake as the vitals of locomotive.Hand braking composition coordinates the driving brake line to brake by worm and gear, being assembled to locomotive at hand braking composition goes forward usually need to carry out the pulling force output test, because the setting height(from bottom) of hand braking composition is higher, minimum also needs 2.2m, when measuring pulling force, the phenomenon that rollover occurs hand braking composition easily occurs, cause the tensile test of hand braking composition comparatively difficult, and Security of test is lower.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of hand braking composition tensile test frock is provided, the tensile test that solves hand braking composition in prior art is comparatively difficult, and the defective that Security of test is lower, realization is carried out tensile test by hand braking composition tensile test frock is convenient to hand braking composition, has improved Security of test.
The technical scheme that the utility model provides is, a kind of hand braking composition tensile test frock, comprise: underframe, brake chain, sprocket wheel and draw-bar donamometer, the two ends of described underframe are respectively arranged with mount pad, one end of described draw-bar donamometer is hinged on described underframe, the other end of described draw-bar donamometer is connected with described brake chain, the rotating side that is connected on described underframe and is positioned at described draw-bar donamometer of described sprocket wheel, and described brake chain is on described sprocket wheel.
Hand braking composition tensile test frock as above wherein is fixed with hinged seat on a described mount pad, and an end of described draw-bar donamometer is hinged on described hinged seat.
Hand braking composition tensile test frock as above is provided with reinforcement on described mount pad, and described reinforcement is fixed on described underframe.
The hand braking composition tensile test frock that the utility model provides, by two mount pads are set, can by two mount pads with the fixed installation of laterally falling of hand braking composition, effectively reduce the height that center of gravity is installed on underframe, reduce the phenomenon that rollover occurs, improved security; In addition, the pulling force that hand braking composition can be exported is delivered on draw-bar donamometer by brake chain, thereby the pulling force to hand braking composition output that can be convenient is measured, realization is carried out tensile test by hand braking composition tensile test frock is convenient to hand braking composition, has improved Security of test.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do one to the accompanying drawing of required use in embodiment or description of the Prior Art and introduce simply, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the use state reference map of the hand braking composition tensile test of the utility model frock embodiment.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the hand braking composition tensile test of the present embodiment frock, comprise: underframe 1, brake chain 2, sprocket wheel 3 and draw-bar donamometer 4, the two ends of underframe 1 are respectively arranged with mount pad 11, one end of draw-bar donamometer 4 is hinged on underframe 1, the other end of draw-bar donamometer 4 is connected with brake chain 2, the rotating side that is connected on underframe 1 and is positioned at draw-bar donamometer 4 of sprocket wheel 3, and brake chain 2 is on sprocket wheel.
Particularly, the hand braking composition tensile test of the present embodiment frock can laterally be fallen hand braking composition by two mount pads 11 on underframe 1 and be fixed assembling, realize reducing the center of gravity of hand braking composition, avoid the phenomenon that rollover occurs hand braking composition occurring in process of the test, improved the security of testing hand braking composition.And when hand braking composition was surveyed pulling force, the pulling force that hand braking composition is exported by worm and gear was delivered in draw-bar donamometer 4 by brake chain 2, and the staff just can learn the pulling force size of hand braking composition output easily by draw-bar donamometer 4.Wherein, for the convenient draw-bar donamometer 4 of installing, wherein be fixed with hinged seat 13 on a mount pad 11 in the present embodiment, an end of draw-bar donamometer 4 is hinged on hinged seat 13.In addition, in order to strengthen the strength of joint between mount pad 11 and underframe 1, be provided with reinforcement 12 on the mount pad 11 in the present embodiment, reinforcement 12 is fixed on underframe 1.
The hand braking composition tensile test of the present embodiment frock, by two mount pads are set, can by two mount pads with the fixed installation of laterally falling of hand braking composition, effectively reduce the height that center of gravity is installed on underframe, reduce the phenomenon that rollover occurs, improved security; In addition, the pulling force that hand braking composition can be exported is delivered on draw-bar donamometer by brake chain, thereby the pulling force to hand braking composition output that can be convenient is measured, realization is carried out tensile test by hand braking composition tensile test frock is convenient to hand braking composition, has improved Security of test.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
