Further technical scheme, bottom, described skeleton outer end is provided with castor.
In the technique scheme, this device is provided with a protective device on the rotation position of back axle testing table (wheel hub), this protective device is by a left side, right protective acoustic cover assembly constitutes, 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 fixedlyed connected with the installing plate of slide assemblies, the two ends of installing plate and middle part are separately installed with the ball slide block, run through in the middle part of the ball slide block and offer through hole, can make slide assemblies integral body be sheathed on the upper beam of base, and then make left, right protective acoustic cover assembly is through the slide assemblies upper beam translation gliding or the upset of base relatively, when protective acoustic cover assembly during along the upper beam sliding translation, be in displacement maximum range and minimum range and be respectively equipped with otic placode on the skeleton, location-plate on this otic placode and the base is fixing spacing through latch, prevent that protective acoustic cover assembly from moving, a left side, 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 back axle testing table welds together.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1. the present invention is by being provided with left and right protective acoustic cover assembly, this protective acoustic cover assembly is slidingly connected through slide assemblies and base, protective acoustic cover assembly is base translation gliding and upset relatively, be convenient to back axle and put into or shift out the back axle testing table, can effectively play the security protection effect, avoid unexpected generation testing table;
2. protective acoustic cover assembly of the present invention is made of the protection network on skeleton and the skeleton, makes that the ventilation and heat performance of testing table is better;
3. protective acoustic cover assembly of the present invention base relatively slides and upset, and is 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.
