Detailed description of the invention
Below in conjunction with Figure of description, the invention will be further described.
As shown in Fig. 1 ~ 4, a kind of impaction simulating trolley device, the chassis 6 that including the fixing guide rail 5 being horizontally set on ground 4, is slidably arranged on fixing guide rail 5 and for providing forward drive to try hard to recommend dynamic chassis 6 drive mechanism 7 of positive movement on fixing guide rail 5 to chassis 6, this trolley device also includes route-variable chassis return photoelectric detection mechanism.
This photoelectric detection mechanism includes the side being fixedly installed on chassis 6 and the photoelectric sensor 1 that can launch light source, the pedestal 2 being arranged on chassis 6 and the multiple raster grids 3 being removably disposed on pedestal 2, when chassis 6 slides on fixing guide rail 5, the light source that photoelectric sensor 1 is launched can be radiated on raster grid 3.Multiple raster grids 3 set gradually along the glide direction of chassis 6 and adjacent two raster grids 3 contact.
This photoelectric detection mechanism also includes the actuating unit electrically connecting and being controlled by photoelectric sensor 1 work with photoelectric sensor 1, and when the light source that photoelectric sensor 1 is launched is radiated on raster grid 3, photoelectric sensor 1 controls actuating unit work.
In this example, actuating unit is motor 8, this trolley device also includes the chain being driven rotation by motor 8, the rotation of chain provides reverse actuating force to chassis 6, pull chassis 6 adverse movement on fixing guide rail 5, when the light source that photoelectric sensor 1 is launched has irradiated raster grid 3, photoelectric sensor 1 controls motor 8 and quits work, and then control chain stops operating to stop it and provides reverse actuating force to chassis 6.
The position that on pedestal 2, corresponding light source irradiates offers through hole 201, and raster grid 3 is positioned at through hole 201.Specifically, pedestal 2 includes connecting portion 202, lower connecting portion 203, be positioned at the both sides of pedestal 2 and both ends respectively with upper connecting portion 202, the side connecting portion 204 of lower connecting portion 203, upper connecting portion 202, lower connecting portion 203, side connecting portion 204 surround above-mentioned through hole 201 jointly.
Offering the holding tank 205 of the upper and lower surface running through connecting portion 202 on upper connecting portion 202 along its length, one end of raster grid 3 makes in stretching into through hole 201 through holding tank 205 that one end of raster grid 3 is mutually detachably connected with lower connecting portion 203, the other end is mutually detachably connected with upper connecting portion 202.Offering escape groove 206 in the position of the corresponding raster grid 3 of lower connecting portion 203, one end of raster grid 3 is positioned at escape groove 206.Raster grid 3 is removably connected with upper connecting portion 202, lower connecting portion 203 phase by bolt respectively.
Specifically, photoelectric sensor 1 is fixedly installed on ground 4, and pedestal 2 is arranged on below chassis 6 and is positioned at chassis 6 side, and pedestal 2 is connected by connector 9 is fixing with chassis 6, and photoelectric sensor 1 and pedestal 2 are positioned at the same side of chassis 6.
