The fork truck visual field test system of the utility model is simple in operation and is capable of facilitating the visual field test of a fork truck quickly.
Description
Technical field
The utility model relates to the technical field of visibility of fork lift truck test, refers in particular to a kind of visibility of fork lift truck test macro.
Background technology
In general, its superior performance of high-quality fork truck often is embodied in high-level efficiency, low cost, high reliability, man-machine work efficiency designs and all many-sides such as convenient for servicing.Wherein, the good visual field is the high efficiency important indicator of fork truck.Because the door frame of fork truck is positioned at the place ahead of pilothouse, can stop the visual field of human pilot, thereby the efficient of fork truck is used in impact.
Yet existing visibility of fork lift truck test macro is to drive fork truck by human pilot to test, and this kind method of testing is comparatively complicated.
Therefore, the inventor makes further research this, develops a kind of visibility of fork lift truck test macro, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of visibility of fork lift truck test macro, and is simple to operate, so that the visibility of fork lift truck test is more convenient.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of visibility of fork lift truck test macro comprises test object, test screen, light fixture and test tool; Light fixture is installed on the fork truck to be tested by test tool, and test object and test screen are positioned over the place ahead of fork truck to be tested, and test object is between test screen and fork truck to be tested, and the light source projects that light fixture sends is on the test screen; By the field of illumination scope of nigration object test light fixture on the test screen.
Further, light fixture comprises the light source that direct supply, a group are comprised of 13 bulbs and the switch that is used for independent each bulb of control.
Further, test object is cube, and its length is 500mm, and width is 500mm, highly is 1200mm.
Further, be provided with grid at the cube face of test object, the width of grid is 100mm, and length is 100mm.
Further, the width of test screen is more than or equal to 500mm.
Further, the surface of test screen is provided with grid, and the width of grid is 100mm, and length is 100mm.
After adopting such scheme, utilize light fixture to replace driver's eyes (being artificial eye), come the analog obstacle thing by the nigration object, carry out visual field test.The utility model compared with prior art, and is simple to operate, can carry out easily the visual field test of fork truck.

Label declaration
Test object 1 test screen 2
Light fixture 3 direct supplys 31
Test tool 4.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As shown in Figure 1, a kind of visibility of fork lift truck test macro that the utility model discloses comprises test object 1, test screen 2, light fixture 3 and test tool 4.Light fixture 3 is installed on the fork truck 5 to be tested by test tool 4.Certainly, test tool 4 can have a variety of, as long as can satisfy light fixture 3 is installed on the fork truck 5 to be tested.In the present embodiment, test tool 4 is that a cover had both gone for the station and drives the formula fork truck, goes for again sitting the support of driving the formula fork truck, with stentplacement in the pilothouse of fork truck, light fixture 3 is placed on the support, with light fixture not being fixed on different positions and direction.
Test object 1 and test screen 2 are positioned over the place ahead of fork truck 5 to be tested, and test object 1 is between test screen 2 and fork truck to be tested 5, and the light source projects that light fixture 3 sends is on test screen 2; The field of illumination scope of position measurement light fixture 3 on test screen 2 by nigration object 1.
Further, light fixture 3 comprises direct supply 31, one group of light source and switch 33 that is comprised of 13 bulbs 32.Direct supply 31 is bulb 32 power supplies, the switch of switch 33 independent each bulb 32 of control.
Further, test object 1 is cube, and its length is the 500mm(millimeter), width is 500mm, highly is 1200mm, is provided with grid at the cube face of test object 1, and the width of grid is 100mm, and length is 100mm.Utilize grid to make marks, can test more accurately the scope of field of illumination.
Further, the width of test screen 2 is more than or equal to 500mm, and the surface of test screen 2 is provided with grid, and the width of grid is 100mm, and length is 100mm.Utilize grid to make marks, can test more accurately the scope of field of illumination.
When using the utility model, open light fixture 3, the light source projects that light fixture 3 sends provides the position of nigration object 1 on test screen 2, the field of illumination scope of test light fixture 3 on test screen 2.The utility model is simple to operate, can carry out easily the visual field test of fork truck.
Above-mentioned only is specific embodiment of the utility model, but design concept of the present utility model is not limited to this, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
