Description
Technical field
The present invention relates to castor technical fields, and in particular to be it is a kind of be mounted on logistics turnover cart castor dress
It sets.
Background technique
The castor wheel footpath being mounted on logistics turnover cart all should not be too large, and the castor of excessive wheel footpath makes loaded goods
Center of gravity it is higher, be easy to cause cargo to topple.Smoothness of the castor of larger wheel footpath when through out-of-flatness ground is better than steamboat
The castor of diameter, but when it encounters step, is difficult to move ahead.
Summary of the invention
It is an object of the invention to overcome the defect that existing castor cannot be up the steps, propose a kind of only to need tractive force just
It can make logistics turnover cart is smoothly up the steps to continue forward caster device.
Realizing the technical solution of above-mentioned purpose is: it is a kind of can top bar caster device, including bearing wheels, wheel carrier and support
Seat, bearing wheels are mounted on wheel carrier, and wheel carrier is mounted on support base, which is characterized in that the wheel carrier is " S " type connecting rod branch
Frame, the top for being somebody's turn to do " S " type connecting rod rack are equipped with a bearing plate, and bearing wheels are mounted on the medium position of " S " type connecting rod rack,
The rear end of " S " type connecting rod rack is mounted on support base by horizontal rotating shaft, the front end of " S " type connecting rod rack be equipped with one it is auxiliary
Wheel is helped, bearing wheel shaft and auxiliary wheel shaft are parallel with the horizontal rotating shaft.
Further, the wheel footpath of the auxiliary wheel is the 1/4~1/3 of bearing wheels wheel footpath.
Further, the wheel footpath of the auxiliary wheel is the 1/3 of bearing wheels wheel footpath.
Further, the two sides of the support base are fixedly installed side plate.
In the present invention, " S " type connecting rod rack is equivalent to a lever main body, and its rear end forms rotation branch on support base
Point, " S " type connecting rod rack can be in vertical direction tiltings.On level land, bearing wheels are in full load state, bearing plate and support
The bottom plane fitting of seat, auxiliary wheel are lifted by " S " type connecting rod rack, are in vacant state.When encountering step, bearing wheels by
To resistance, due to the presence of external traction force, step edge at this time becomes the fulcrum of a power, resistance and tractive force herein
Between formed a upward resultant force, this makes bearing wheels off-loading with joint efforts and is lifted up, at the same time, " S " type connecting rod rack by
Power conversion, keeps front sagging, and auxiliary wheel gradually decreases down on step surface and bearing load.Continue to act in external traction force
Under, bearing wheels are fully raised to step surface, auxiliary wheel almost bearing load and rolls forward.After up the steps,
Under gravity, " S " type connecting rod rack resets, and bearing wheels are in full load state again naturally, and auxiliary wheel is lifted again.So far,
Entire caster device returns back to original state again, and top bar is completed.
Simple structure of the present invention, it is reasonable and exquisite to design, and being mounted on logistics turnover cart only can with horizontal drag force
Make cart smoothly step up height to be slightly less than the step of bearing wheels radius and continue to move ahead.

Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
As shown in Figure 1 to Figure 3, the present invention includes bearing wheels 3, wheel carrier and support base 1, support base 1 and logistics turnover cart
Bottom plate be fixedly connected, wheel carrier is mounted on support base 1, and difference with the prior art is, the wheel carrier is that " S " type connects
Bar bracket 2, bearing wheels 3 are mounted on the medium position of " S " type connecting rod rack 2, and the rear end of " S " type connecting rod rack 2 is turned by horizontal
Axis 202 is mounted on support base 1, and the front end of " S " type connecting rod rack 2 is equipped with an auxiliary wheel 4, the wheel shaft of bearing wheels 3 and auxiliary
Help the wheel shaft of wheel 4 parallel with horizontal rotating shaft 202.Specific detailed construction is as described below:
As shown in Figures 2 and 3, the rear end of support base 1 is equipped with the rack shaft hole 102 of a horizontal direction." S " type connecting rod branch
The top of frame 2 is equipped with a bearing plate 201, and rear end top position is equipped with a horizontal rotating shaft 202, and middle part is equipped with a bearing wheels
Axis hole 203, front end are equipped with an auxiliary axle hole 204.Rack shaft hole 102 is adapted to horizontal rotating shaft 202；Bearing wheels axis hole 203
It is adapted to bearing wheel shaft 301；Auxiliary axle hole 204 is adapted to auxiliary wheel shaft 401.The rear end of " S " type connecting rod rack 2 passes through level
Shaft 202 is mounted on the rack shaft hole 102 of support base 1；Bearing wheels 3 are mounted on bearing wheels axis hole 203 by bearing wheel shaft 301
On；Auxiliary wheel 4 is by assisting wheel shaft 401 to be mounted on auxiliary axle hole 204.
In the present invention, the wheel footpath of auxiliary wheel 4 is the 1/4~1/3 of 3 wheel footpath of bearing wheels.
As a preferred embodiment, the wheel footpath of auxiliary wheel 4 is the 1/3 of 3 wheel footpath of bearing wheels.
As shown in figures 1 and 3, in the present invention, the two sides of support base 1 are fixedly installed side plate 101.Side plate 101 can be to " S "
Type connecting rod rack 2 plays position-limiting action.
The working mechanism for capableing of top bar to the present invention with reference to the accompanying drawing makes parsing.
As shown in figure 4, bearing wheels 3 are in full load state, the bearing plate 201 on " S " type connecting rod rack 2 on level land
It is bonded with the bottom plane of support base 1, auxiliary wheel 4 is lifted by " S " type connecting rod rack, is in vacant state.
As shown in Figure 4 and Figure 5, when encountering step the radius of bearing wheels 3 (height of step be less than), bearing wheels 3 by
Resistance, due to the presence of external traction force, step edge at this time becomes the fulcrum of a power, resistance (F hereinResistance) and traction
Power (FIt leads) between formed a upward resultant force (FIt closes), this makes 3 off-loading of bearing wheels with joint efforts and is lifted up, at the same time, " S " type
2 stress check calculation of connecting rod rack, its rear end rotate and are upturned around rack shaft hole 102, and front is sagging, makes the auxiliary wheel 4 of front end
It gradually decreases down on step surface and bearing load, bearing plate 201 at this time is also detached from the bottom plane of support base 1.
As shown in Figure 6 and Figure 7, in external traction force (FIt leads) continue under effect, bearing wheels 3 are fully raised to step surface
On, the almost bearing load of auxiliary wheel 4 and rolls forward.After up the steps, bearing wheels 3 are in full load state again naturally,
By load gravity (FGravity) and tractive force (FIt leads) influence, bearing wheels 3 generate reply resultant force under the action of " S " type connecting rod rack 2
(FIt is compound), auxiliary wheel 4 is lifted again.So far, entire caster device returns back to original state again.As logistics turnover cart
Continue to move ahead.
