Abstract
The utility model relates to the technical field of mechanical support, in particular to an improved idler wheel mechanism used for supporting a mixing pot of a concrete transit mixing truck. The improved idler wheel mechanism comprises a pair of supporting assemblies and is characterized in that each supporting assembly comprises two idler wheels, a supporting frame and a base, wherein the supporting frame is fixedly connected with the base and the two idler wheels are respectively installed at the tops of left and right ends of the supporting frame. Compared with the prior art, the improved idler wheel mechanism has a large stressed area and the stress is reduced; a contact angle is increased and the stability of the whole truck is better; and since the thickness of the bases and the supporting frames is increased, the idler wheel mechanism is more stable, has prolonged service life and is safe and reliable.
Description
Technical field
The utility model relates to the mechanical support technical field, specifically a kind of improved idler wheel mechanism that is used to support the concrete mixing and transporting car agitator tank.
Background technology
Concrete mixing and transporting car when work mainly is to accomplish charging, stirring, transportation and discharge operation by agitator tank, thereby during concrete mixing and transporting car work, its agitator tank is in rotary state constantly.The agitator tank front end connects reductor and is supported on the foreground of concrete mixer truck, and the rear end rail support forms supported at three point on the idler wheel mechanism on backstage, under the drive of reductor, rotate.Because during concrete mixer truck work, relative rolling takes place in agitator tank and roller constantly, thereby the requirement of pair roller mechanism is than higher.The idler wheel mechanism that available coagulation soil trucd mixer uses has two rollers to constitute; The defective that two aspects are arranged: the theoretical listing of agitator tank roller track is circular on the one hand, but because tank body weight is big, the rolling wheel guide rails easy deformation; In the actual moving process; Be elliptic orbit, and can produce rigid impact between the roller, the roller supporting mechanism is easy to damage; The surface roller support angle is little under the agitator tank tube on the other hand, and trucd mixer driving process middle part is stable, and special city runs at high speed and when turning, overturns easily.Existing idler wheel mechanism in use is easy to damage for the concrete mixer truck of generous amount, and short must often the replacing not only wasted resource but also needed a large amount of maintenance times service life, can not satisfy instructions for use.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of idler wheel mechanism of improved concrete mixing and transporting car is provided, and is rational in infrastructure, supports secure, and long service life has solved the flimsy problem of idler wheel mechanism.
In order to achieve the above object; The utility model has designed a kind of improved concrete mixing and transporting car idler wheel mechanism; Comprise a pair of supporting component; It is characterized in that: this supporting component is made up of two rollers, bracing frame and bases, and bracing frame is fixedly connected on the base, and two rollers are installed in the top of bracing frame right ends respectively.
Described bracing frame is a trapezium structure, forms an inclined-plane between two rollers, this inclined-plane and horizontal plane formation angle β=and 30～45 °.
The utility model is compared with prior art, and the lifting surface area of idler wheel mechanism increases, stressed reduction; Contact angle increases, and the stability of car load is better; The enlarged in thickness of base and bracing frame makes idler wheel mechanism firm more, has increased service life, and is safe and reliable.
Description of drawings
Fig. 1 is used for the structural representation of concrete mixing and transporting car agitator tank for existing idler wheel mechanism.
Fig. 2 is used for the structural representation of concrete mixing and transporting car agitator tank for the utility model.
Fig. 3 is the structural representation of supporting component in the utility model.
Referring to Fig. 1, Fig. 2 and Fig. 3,1 is agitator tank; 2 is the idler wheel mechanism of prior art; 3 is vehicle frame; 4 is the supporting component of idler wheel mechanism; 41 is roller; 42 is bracing frame; 43 is base.
The specific embodiment
Combine accompanying drawing that the utility model is further specified at present.
Be illustrated in figure 1 as the structural representation of the idler wheel mechanism of existing concrete agitator truck, idler wheel mechanism 2 is fixedly installed on the vehicle frame 3, and the rail supported of agitator tank 1 is on idler wheel mechanism 2.This design can be satisfied the concrete mixing and transporting car instructions for use of 5m3～10m3 preferably; But the concrete mixing and transporting car for generous amount more than the 10m3 then can not meet the demands; On the one hand the less meeting of support angle α causes concrete mixing and transporting car to go steadily not overturning easily, and the excessive idler wheel mechanism of weight damages easily on the other hand.
As shown in Figures 2 and 3; The utility model comprises a pair of supporting component 4, and this supporting component is made up of two rollers 41, bracing frame 42 and base 43, and bracing frame 42 is fixedly connected on the base 43; Two rollers 41 are installed in the top of bracing frame 42 right ends respectively; Bracing frame 42 is a trapezium structure, forms an inclined-plane between two rollers 41, this inclined-plane and horizontal plane formation angle β=and 30～45 °.
The four rolling 41 of the utility model supporting component 4 makes the idler wheel mechanism lifting surface area increase, thereby makes stressed reduction, and the increasing of the volume of base 43 and bracing frame 42, makes idler wheel mechanism firm more, has increased service life; The design of four rolling 41 simultaneously makes contact angle α bigger than the contact angle α of prior art, makes that the stability of car load is better, safe and reliable.
