Abstract
The utility model discloses a self-centring roller mechanism for a concrete mixing carrier, which is arranged in coordination with a roller track of a mixing tank of the concrete mixing carrier. The self-centring roller mechanism comprises a pair of roller support subassemblies, each of which comprises a support saddle, rollers, a connecting plate and a shaft; the support saddle is fixedly arranged on the frame of the concrete mixing carrier; the rollers are two in number and are fixedly arranged in symmetry on the connecting plate which is connected with the support saddle through the shaft; the connecting plate can rotate around the shaft; and the two rollers and the shaft form a steady triangular structure. The four-roller support mechanism improves the stress strain of the roller support mechanism and is reasonable in structure, long in service life, safe and reliable.
Description
Technical field
The utility model belongs to mechanical support mechanism, is specifically related to a kind of agitator tank roller supporting mechanism of concrete mixing and transporting car.
Background technology
Concrete mixing and transporting car work the time mainly is to finish 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 guide supporting forms supported at three point on the idler wheel mechanism on backstage, rotate under the drive of reductor.Because during concrete mixer truck work, relative rolling takes place with roller in agitator tank constantly, thereby pair roller mechanism requires than higher.The idler wheel mechanism that known concrete mixer truck is used has two rollers to constitute, and shown in figure one, 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 2.5m can be better satisfied in this design
3-10m
3The concrete mixer truck instructions for use, but for 10m
3More than generous amount concrete mixer truck, this kind roller system is in use very fragile, service life is shorter, can not satisfy instructions for use.Concrete reason is as follows: the agitator tank roller track is circular in theory on the one hand, but because tank body weight is big, and the rolling wheel guide rails easy deformation in the actual moving process, is an 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 is unstable in the trucd mixer driving process, particularly runs at high speed and overturns easily when turning.
The utility model content
In order to overcome the above-mentioned defective that the known technology field exists, the purpose of this utility model is, a kind of concrete mixing and transporting car self-centering idler wheel mechanism is provided, stressed, long service life, safe and reliable rational in infrastructure, as to have improved the roller supporting mechanism.
The concrete mixing and transporting car self-centering idler wheel mechanism that the utility model provides, be equipped with the agitator tank rolling wheel guide rails of concrete mixing and transporting car, comprise a pair roller supporting component, described roller supporting component comprises bearing, roller, connecting plate, axle, bearing is fixedly installed on the vehicle frame, described roller is two, two roller symmetries are fixedly installed on the connecting plate, be connected by axle between connecting plate and the bearing, connecting plate can sway, and two rollers are stable triangular structure with 3 on axle.
The concrete mixing and transporting car self-centering idler wheel mechanism that the utility model provides, its beneficial effect is, the roller supporting component can be adjusted supporting gravity automatically with rotation, the vibrations of agitator tank, 4 rollers closely contact with the agitator tank roller track all the time, because contact angle α is bigger than known two roller supporting mechanism α angles, so it is whole vehicle stability is good, safe and reliable in travelling; Because two rollers of four rolling and guide rail contact gear ratio contact one times of stressed reduction, so the roller stress situation is improved greatly.Stressed, long service life, safe and reliable that this four rollers supporting mechanism is rational in infrastructure, improved the roller supporting mechanism.
Description of drawings
Fig. 1 is the structural representation of known roller supporting mechanism;
Fig. 2 is the overall structure schematic diagram of an embodiment of the utility model;
Fig. 3 is a roller supporting mechanism structure for amplifying schematic diagram among Fig. 2.
Mark among the figure:
1. agitator tank; 2. idler wheel mechanism; 3. vehicle frame; 5. agitator tank, 6. roller supporting component; 7. vehicle frame; 8. roller; 9. connecting plate; 10. bearing; 11. axle.
The specific embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the concrete mixing and transporting car self-centering idler wheel mechanism that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1-Fig. 3, the concrete mixing and transporting car self-centering idler wheel mechanism of present embodiment, be equipped with the rolling wheel guide rails of the agitator tank 5 of concrete mixing and transporting car, comprise a pair roller supporting component 6, this roller supporting component 6 is fixedly installed on the vehicle frame 7, described roller supporting component 6 comprises bearing 10, roller 8, connecting plate 9, axle 11, bearing 10 is fixedly installed on the vehicle frame 7, described roller 8 is two, two roller symmetries are fixedly installed on the connecting plate 9, be connected by axle 11 between connecting plate 9 and the bearing 10, connecting plate 9 can rotate around axle 11, and two rollers and 3 on axle are stable triangular structure.
In the course of work, the roller supporting component can be adjusted supporting gravity automatically with rotation, the vibrations of agitator tank, and 4 rollers contact with the agitator tank roller track all the time.Because contact angle α is bigger than known two roller supporting mechanism α angles, and is so whole vehicle stability is good, safe and reliable in travelling.
