Detailed description of the invention
This utility model is described further with embodiment referring to figs. 1 through Fig. 5.
A kind of rollover stand, the bracing frame 2 as shown in Fig. 1 to Fig. 2, include underframe 1, being fixed on underframe 1, is fixed on bracing frame 2 upper end for the rotation dish 9 supporting engine assembly and the oil drain pan 10 being detachably arranged on underframe 1.Wherein, underframe 1 is supported on ground by four universal caster wheels 3, and when needs move integrally rollover stand to appointed place, motive force can be reduced by the rolling friction form between universal caster wheel 3 and ground, is convenient to the movement of rollover stand.
As shown in Figure 3, rotation dish 9 is provided with is furnished with multi-angle movable rod installing mechanism, can conveniently install the engine assembly of different model.In order to engine assembly is carried out the adjustment in angle and orientation by convenient for maintaining and real training personnel, in bracing frame 2, it is provided with worm and gear assembly 7, in order to drive circumferentially rotating of rotation dish 9 to meet angle adjustment to electromotor.Utilize the bearing capacity of worm and gear assembly 7 so that rotation dish 9 can meet the installation of the engine assembly of polytypic.Specifically, worm gear and rotation dish 9 link, and worm screw is driving link, the outside of bracing frame 2 is provided with handle 8, worm screw can be driven to rotate by rotary handle 8, thus rotary motion being transferred on rotation dish 9 so that it is frame 9 is rotated and rotates to arbitrary orientation.
As shown in Figure 4, the weight of general engine assembly is up to 1.6 tons, therefore, after installing engine assembly, needing to be completely fixed to rollover stand prevents it from sliding and tumbling, the present embodiment is additionally provided with at least 3 group supporting mechanisms 4 corresponding to four universal caster wheels 3 on underframe 1, in order to overall rollover stand fixing after installing engine assembly.Supporting mechanism 4 includes leg 41, pole 42 and elevator 43, wherein, leg 41 directly contacts with ground, it is provided with by skid resistant course (not shown) bottom it, when supporting mechanism 4 supports overall rollover stand, leg 41 is butted on the supporting role replacing universal caster wheel 3 on ground, so eliminates the rolling of universal caster wheel 3, also increase the contact area of rollover stand and ground simultaneously, improve overall rollover stand stability of strutting system on the ground.Pole 42 and elevator 43 form the fit form of screw pair, wherein elevator 43 is fixed with the bottom surface of underframe 1, when rotary supporting rod 42 makes that pole 42 is relative with elevator 43 to be rotated, pole 42 drives leg 41 to move to earth surface gradually and is propped by rollover stand, replacing the supporting role of universal caster wheel 3, so fixing rollover stand prevents it from sliding and the degree of freedom tumbled in background technology occurring.
More specifically, be additionally provided with oil drain pan 10 on the upper surface of underframe 1, it is possible to accept the lubricating oil of the outflow of the engine assembly on rotation dish 9 and place some conventional dismantling devices.
As shown in Figure 5, for the moving of centre of body weight when facilitating operator's operation, relatively stand on ground and be more conducive to firmly, improve the friendliness of man-computer cooperation, on underframe 1, symmetry is additionally arranged two pieces of Working pedals 5 and slide rail 6, Working pedal 5 can slide along slide rail 6 and stretch out, and is butted on ground to one end and supports rollover stand together with a support component 4.Wherein Working pedal 5 includes the first flap 51 and the second flap 52, both are one-body molded, first flap 51 is provided with sliding shoe 511, in order to connect Working pedal 5 on slide rail 6, second flap 52 turns down downwards a less angle relative to the first flap 51, when making the second flap 52 be butted on ground, between second flap 52 and ground, angle is 12 degree, this angle accords with the ergonomic designs that human body is stood so that operator are with optimum comfort angle and are easiest to make the orientation of power step on Working pedal 6.Additionally, for the coefficient of friction of the bottom Yu ground contact portion of improving Working pedal 6 and protect flooring simultaneously, on the second flap 52, the edge bottom with earth surface posts anti-slip rubber 521, to ensure the coefficient of friction between the second flap 52 and ground.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
