Abstract
The utility model discloses a riding wheel device used in the mixing drum for the concrete mixing and transporting vehicle, comprising a riding wheel bottom frame (3). The device is characterized in that the riding wheel bottom frame (3) is movably connected with a riding wheel frame (6) through a spindle (4); the two ends of the riding wheel frame (6) are symmetrically connected with a riding wheel (1) respectively through a riding wheel axis (2); the axle centers of the two riding wheel axes(2) in the two ends and the axle center of the spindle (4) are distributed as an isosceles triangle. The utility model can increase the running stability of the mixing drum, improve the lateral stability of the whole vehicle and prolong the service life of the riding wheel.
Description
Technical field:
The utility model relates to a kind of riding wheel apparatus, relates in particular to a kind of concrete mixing and transporting car mixing drum riding wheel apparatus.
Background technology:
At present, the riding wheel apparatus of concrete mixing and transporting car mixing drum all adopts the single mount wheel construction that is symmetrically arranged, but because the single mount wheel does not have dynamic adjustable, when mixing drum is subjected to the external force influence, road injustice for example, jolt etc., can make mixing drum axis generation displacement, the suffered impact of mixing drum will be directly delivered on the bearing of supporting-roller shaft and support roller inside, cause the support roller discontinuity, make support roller shortening in service life, and because absorbent harmful the beating of bearing of conveyor idler institute has certain limit, so the stability and the security meeting of mixing drum running are affected.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and a kind of raising mixing drum run stability is provided, and increases the lateral stability of car load, the concrete mixing and transporting car mixing drum riding wheel apparatus that has prolonged the service life of support roller simultaneously.
The purpose of this utility model can reach by following measure: a kind of concrete mixing and transporting car mixing drum riding wheel apparatus, it has support roller underframe 3, it is characterized in that support roller underframe 3 flexibly connects roller frame 6 by axle 4, the two ends of roller frame 6 connect a support roller 1 by supporting-roller shaft 2 symmetries respectively, and the axle center of two supporting-roller shaft 2 at two ends and the axle center of axle 3 are isosceles triangle and distribute.
In order further to realize the purpose of this utility model, described roller frame 6 is flat ∨ type.
In order further to realize the purpose of this utility model, be connected by bearing 5 between described support roller 1 and the supporting-roller shaft 2.
Compared with the prior art the utility model has following good effect: because the utility model adopts the double supporting wheel structure, solved that the agitator truck mixing drum is beated and mixing drum axis running skew problem, it is more steady that the design of this product makes agitator truck mix tube running, and safety coefficient increases greatly.The entire work process of concrete mixing and transporting car: trucd mixer is concrete factory makes mixing drum turn round clockwise to put into the concrete that has stirred with the speed of 6-10r/min after, in transporting the way in building site to, mixing drum is with the clockwise low-speed running of the speed of about 1-3r/min, concrete to carrying ceaselessly stirs, to prevent the phenomenon of segregation, mixing drum is rotated counterclockwise discharging with the speed of 6-12r/min again behind the arrival building site.The power that mixing drum rotates is provided by chassis, and support roller plays a supportive role to mixing drum.Trucd mixer when operation mixing drum is suffered jolts and destabilizing factor such as impact, and the double supporting wheel structure can be adjusted angle voluntarily, thereby guarantees the mixing drum running steadily.Adopt the bracing or strutting arrangement of double supporting wheel structure as mixing drum, its effect is whole service weights of carrying mixing drum, limit lateral is tumbled, guarantee that mixing drum is around its axis normal rotation, its unique design makes it that enough bearing capacitys be arranged, and its steering resistance to mixing drum is little, and supporting member is had automatic adjustment capability because of the interference that the work distortion causes, obviously improved and mixed a run stability, guaranteed the quality of ready-mixed concrete in stirring transportation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the top plan view of Fig. 1;
Fig. 3 is the user mode reference diagram of existing single mount wheel construction riding wheel apparatus;
Fig. 4 is a user mode reference diagram of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing preferred forms of the present utility model is elaborated,
Embodiment: a kind of concrete mixing and transporting car mixing drum uses riding wheel apparatus (referring to Fig. 1, Fig. 2), it has support roller underframe 3, fix the integral position of riding wheel apparatus by fixing support roller underframe 3, roller frame 6 is connected on the support roller underframe 3 by axle 4, and can rotate to an angle around axle 4, roller frame 6 is flat ∨ type, the two ends of roller frame 6 connect support roller 1 by supporting-roller shaft 2 symmetries respectively, be connected by bearing 5 between support roller 1 and the supporting-roller shaft 2, the axle center of two supporting-roller shaft 2 at two ends and the axle center of axle 3 are isosceles triangle and distribute, axle 3, supporting-roller shaft 2, support roller 1 and bearing 5 are main load-bearing components, two support rollers 1 can be around axle 4 transhipments, can make in use two support rollers 1 can with mixing drum track even contact, thereby guarantee that two support rollers are stressed evenly, reach overall operation purpose stably.The axle of traditional two riding wheel apparatus of single mount wheel construction and the center angle of mixing drum 8 are 60 ° of (see figure 3)s, in double supporting wheel structure of the present utility model, the support roller of two riding wheel apparatus can be increased to 70 ° of (see figure 4)s to the maximum containing angle of mixing drum 8, obviously improved and mixed a run stability, guaranteed the quality of ready-mixed concrete in stirring transportation.
