Further technical scheme, described slide assemblies comprises installing plate and is arranged at respectively the ball slider at installing plate two ends and middle part, described installing plate is fixedly connected with the underbeam of described skeleton, run through being provided with through hole in the middle part of the described ball slider, described slide assemblies is located on the upper beam of described base through described through hole slip cap.
Further technical scheme, described ball slider comprises forward and backward cover plate, two cover plates are threaded connection, be provided with back up pad between two cover plates, described back up pad upper end offers the mounting groove that U-shaped groove consists of installing plate, described cover plate and back up pad middle part offer through hole, and looping chute between the upper beam of described back up pad and described base is provided with ball in the described chute.
Further technical scheme, be positioned at the relative base sliding maximum range of skeleton and minimum range place on the described skeleton and be provided with respectively otic placode, be engaged in base with described otic placode and be provided with location-plate, described otic placode and location-plate are fixing spacing through latch, consist of described position limiting structure.
Further technical scheme, bottom, described skeleton outer end is provided with castor.
In the technique scheme, this device arranges a protective device at the rotation position of rear-axle test bed (wheel hub), this protective device is by a left side, right protective acoustic cover assembly consists of, this protective acoustic cover assembly comprises the protective cover skeleton and is arranged at protection network on the skeleton, the underbeam of described skeleton is fixedly connected with the installing plate of slide assemblies, two ends and the middle part of installing plate are separately installed with ball slider, run through in the middle part of the ball slider and offer through hole, can so that slide assemblies integral body be sheathed on the upper beam of base, and then so that left, right protective acoustic cover assembly is through relatively upper beam translation gliding or the upset of base of slide assemblies, when protective acoustic cover assembly during along the upper beam sliding translation, be in skeleton in displacement maximum range and minimum range and be respectively equipped with otic placode, location-plate on this otic placode and the base is fixing spacing through latch, prevent that protective acoustic cover assembly from moving, left, back axle can be removed or put in protective acoustic cover assembly after right protective acoustic cover assembly is opened, the base of base and rear-axle test bed welds together.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. the present invention is by arranging left and right protective acoustic cover assembly, this protective acoustic cover assembly is connected with base sliding through slide assemblies, protective acoustic cover assembly is base translation gliding and upset relatively, be convenient to back axle and put into or shift out rear-axle test bed, can effectively play safety protection function to testing table, avoid unexpected generation;
2. protective acoustic cover assembly of the present invention is made of the protection network on skeleton and the skeleton, so that the ventilation and heat performance of testing table is better;
3. relatively base sliding and upset of protective acoustic cover assembly of the present invention, easy to operate, reduced laborer's working strength;
4. the present invention is simple in structure, and is easy to use, and is easy to realize, is fit to promote the use of.
