At present, lack a kind of easy to operate, structure is simple, the obvious loading test device of demonstrating effect.
Summary of the invention
The present invention is intended at least solve one of problems of the prior art.
The technical problem to be solved in the present invention is to provide a kind of easy to operate, and structure is simple, the obvious loading test device of demonstrating effect.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: it comprises frame, be arranged on above described frame for load load particle funnel device, being arranged on weighing device below described frame, being placed on described weighing device for placing the brace table of model to be measured, also comprise displacement over-run measuring device, described displacement over-run measuring device is made up of the buzzer siren of picking sensor and the described picking sensor signal of reception, described picking sensor is arranged in described frame, for respond to described model to be measured loading after the change of amount of deflection.
Further, described brace table is made up of the end face for placing described model to be measured, the bottom surface be connected with described weighing device and the support bar that connects described end face and described bottom surface.
Further, the exit of described funnel device is provided with valve.
Further, described weighing device is electronic platform scale.
Further, also retracting device is provided with in the below of described frame.
Beneficial effect of the present invention there are provided a kind of granule impact charger, structure of the present invention is simple, be easy to operation, by described picking sensor respond to model to be measured load particle Impulsive load under amount of deflection change, then by described buzzer siren react model to be measured load test whether lost efficacy.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the embodiment of a kind of granule impact charger of the present invention.
Embodiment
Hereafter will describe the present invention in detail in conjunction with specific embodiments.It should be noted that the combination of technical characteristic or the technical characteristic described in following embodiment should not be considered to isolated, they can mutually be combined thus be reached better technique effect.
Embodiment
Figure 1 shows that the structural representation of the embodiment of a kind of granule impact charger of the present invention.
Embodiments of the invention are described in detail: it comprises frame 1 below in conjunction with Fig. 1, be arranged on above described frame 1 for loading the funnel device 2 loading particle, be arranged on the weighing device 3 below described frame 1, be placed on described weighing device 3 for placing the brace table 4 of model to be measured, also comprise displacement over-run measuring device 5, described displacement over-run measuring device 5 is made up of the buzzer siren (not shown) of picking sensor 51 and described picking sensor 51 signal of reception, described picking sensor 51 is arranged in described frame 1, for respond to described model to be measured loading after the change of amount of deflection.
In the present embodiment, described brace table 4 is made up of the end face for placing described model to be measured, the bottom surface be connected with described weighing device 3 and the support bar that connects described end face and described bottom surface, described support bar is that four hex bolts are as support bar, the inscribe diameter of hex bolts is 15mm, and it is the square of 300mm that four bolt-center form a length of side.
In the present embodiment, described loading particle adopts steel ball, and it is 100kg that this device loads particle maximum gross weight; The sidewall of described funnel device 2 is made up of four pieces of poly (methyl methacrylate) plates, and the angle of each block sidewall and surface level is all about 45 °, and the steel ball outlet out-to-out below described funnel device 2 is 170mm × 170mm, and inner dead size is 150mm × 150mm.Have a valve (not shown) in steel ball outlet, this valve is loading height to the distance of described brace table 4 end face, equals 720mm.
In the present embodiment, described weighing device 3 is electronic platform scale, and precision is at least 10g.
In the present embodiment, described safety light curtain sensor 51 launches 10 infrared rays altogether, and infrared level spacing is 40mm.Infrared ray is 30mm to the initial distance at bolt top, and when described model to be measured loads, amount of deflection exceedes this distance, reach hinder infrared ray through time, described buzzer siren can continue to report to the police (glisten and pipe).
In the present embodiment, retracting device (not shown) is also provided with in the below of described frame 1.
The load mode of the present embodiment is as follows:
By the disposable Impulsive load of steel ball in funnel device 2, Impulsive load height H=720mm, loading general assembly (TW) is 80kg; If model to be measured cannot contain residence steel ball, then unnecessary steel ball flows in the retracting device of described frame 1 bottom.Keep 20 seconds after loading, take model to be measured and contain the general assembly (TW) Ga of steel ball, then (Gm is model weight to be measured to Weight Loaded G=Ga-Gm, and unit is g).
Loading and testing procedure comprise:
(1) first model to be measured is placed on described brace table 4, the 80kg steel ball then in the complete described funnel device 2 of disposable loading.
(2) loading complete process, described displacement over-run measuring device 5 is all in opening.Because steel ball falls to causing intermittence or transience to report to the police, do not belong to load and lost efficacy.
Load and in testing procedure, when loading steel ball, pin described valve switch, surprisingly spilling when unripe loading to avoid steel ball; During loading procedure disposable open fast described valve load, do not stop in centre.
The invention provides a kind of granule impact charger, structure of the present invention is simple, be easy to operation, by described picking sensor 51 respond to model to be measured load particle Impulsive load under amount of deflection change, then by described buzzer siren react model to be measured load test whether lost efficacy.
In description of the invention, term " installation ", " setting " and " connection " etc. all should be interpreted broadly, and such as, " connection " can be fixedly connected with, and also can be removably connect, or connects integratedly; Can be direct connection, also can be indirectly connected by intermediary.For the ordinary skill in the art, above-mentioned term concrete meaning in the present invention can be understood as the case may be.
Although give some embodiments of the present invention, it will be understood by those of skill in the art that without departing from the spirit of the invention herein, can change embodiment herein.Above-described embodiment is exemplary, should using embodiment herein as the restriction of interest field of the present invention.
