Using very extensive in industry, still, there are still some to ask in actual use for common flat-plate trolley currently on the market
Topic；
For example the common flat-plate trolley overwhelming majority uses two universal wheels and two directional wheels currently on the market, two
Universal wheel is arranged close to one end of knob, and this design is pushed compared to the flat-plate trolley of all universal wheels of four wheels
It is more prone to control direction of advance, but the flat-plate trolley for turning to but universal wheel more all than four wheels is harder,
Especially when turning enters in elevator, it is often necessary to flat-plate trolley is moved with hand, its vehicle body is made to move just, such flat-plate trolley
It can just can smoothly enter into elevator, be difficult to move, it is often necessary to more people if being mounted with the cargo of heavier mass on flat-plate trolley
Common auxiliary could move, and time-consuming and laborious, practicability is not strong.
Invention content
The purpose of the present invention is that providing a kind of universal wheel quantity Adjustable horizontal wrench to solve the above-mentioned problems pushes away
Vehicle, if only harder there are two being turned to when universal wheel to solve flat-plate trolley traditional in the prior art, if four wheels
Then direction of advance is difficult to control when all universal wheels, and there are many deficiencies during use, can not be according to actual use situation
The problems such as quantity of adjust automatically universal wheel.Preferred technical solution can be realized flat in many technical solutions provided by the invention
Wrench cart is according to the quantity of actual use situation adjust automatically universal wheel, so as to being capable of tablet easy to use in the case of various
Trolley effectively solves current flat-plate trolley and there are the technique effects such as problems in actual use, as detailed below
It illustrates.
To achieve the above object, the present invention provides following technical schemes：
A kind of adjustable flat-plate trolley of universal wheel quantity provided by the invention, including cargo loading plate and it is hinged on the loading

Dynamic motor rotation drives the position that the driving gear drives the driven gear rotation to adjust the idler wheel, until the idler wheel
Central axial direction parallel with the width direction of the cargo loading plate (angular transducer is with the central axis side of the idler wheel
To it is parallel with the width direction of the cargo loading plate when shaft position be starting point, it is described when the idler wheel is universal wheel
Angular transducer can detect the angle of the shaft rotation and by angle information transfer to the processor in real time, by described
The PLC is passed to after processor processing, when needing the idler wheel to be adjusted to directional wheel, if the shaft is not rising at this time
Point position, then the PLC just control the driving motor rotation driving gear driven to drive the driven gear rotation, directly
Rotated to the shaft to start position), then, the PLC controls the electromagnetic brake and brakes the shaft, makes described turn
Axis maintains static, at this point, the idler wheel is just adjusted to directional wheel, facilitates flat bed transport vehicle straight-line travelling, efficiently solves four
The problem of wheel is the flat-plate trolley direction of advance bad control of universal wheel, it is automatic according to actual use situation to realize
The quantity for adjusting universal wheel effectively solves mesh to be capable of the technique effect of flat-plate trolley easy to use in the case of various
There are problems in preceding flat-plate trolley, practicability is good in actual use；As to how setting program makes the PLC certainly
It moves the control electromagnetic brake, the driving motor, the linear motor and acts and belong to existing programming technique, be not necessarily to herein superfluous
It states.
Advantageous effect is：A kind of adjustable flat-plate trolley of universal wheel quantity of the present invention can be according to actually making
With the quantity of situation adjust automatically universal wheel, so as in the case of various can flat-plate trolley easy to use, effectively solve mesh
There are the technique effects such as problems in preceding flat-plate trolley, practicability is good in actual use.

A kind of above-mentioned adjustable flat-plate trolley of universal wheel quantity, during use, operator can operate tactile as needed
It touches screen 18 and sends out an operational order to PLC16, the operational order that processor 17 inputs operator handles and will processing
Command information afterwards passes to PLC16, and PLC16 makes idler wheel 13 in universal wheel according to command information control tourelle action and leads
To free switching between wheel, to satisfy the use demand；When it is to need all universal wheel of four wheels that operator, which sends out instruction,
Electromagnetic brake 4 in PLC16 control brakings stops braking, while controlling the rotation of linear motor 9 and pulling driving motor 8 to separate
The direction of electromagnetic brake 4 is moved, until driving gear 7 is detached with driven gear 6, at this point, shaft 5 is free to rotate,
Idler wheel 13 is universal wheel, and when four rolling 13 is universal wheel, operator can carry out cornering operation, such as flat-plate trolley horse
When upper needs turning enters elevator, four rolling 13 can be controlled in advance and is all adjusted to universal wheel, just reduces tablet hand in this way
The turning radius of cart can smoothly enter into elevator convenient for flat-plate trolley, and the flat-plate trolley for efficiently solving two universal wheels turns
Curved radius is larger, it is difficult to the problem of being directly entered elevator；When it is universal wheel that the instruction that operator sends out, which is two wheels of needs,
(being usually front-wheel, can also be trailing wheel, during actual use can be set by operation touch-screen 18), PLC16 controls
Linear motor 9 pushes driving motor 8 to be moved to close to the direction of electromagnetic brake 4, until driving gear 7 is nibbled with driven gear 6
It closes, then the rotation of driving motor 8 driving driving gear 7 drives the position of the rotation adjustment idler wheel 13 of driven gear 6, until idler wheel 13
Central axial direction parallel with the width direction of cargo loading plate 1 (angular transducer 26 is with the central axial direction and load of idler wheel 13
The position of shaft 5 is starting point when the width direction of goods plate 1 is parallel, and when idler wheel 13 is universal wheel, angular transducer 26 can be real
When the angle that rotates of detection shaft 5 and by angle information transfer to processor 17, passed to after the processing of processor 17
PLC16, when needing the idler wheel 13 to be adjusted to directional wheel, if for shaft 5 not in start position, PLC16 just controls driving at this time
The rotation driving driving gear 7 of motor 8 drives driven gear 6 to rotate, up to the rotation of shaft 5 to start position), then, PLC16 controls
Electromagnetic brake 4 processed brakes shaft 5, so that shaft 5 is maintained static, at this point, idler wheel 13 is just adjusted to directional wheel, facilitates flat bed delivery
Vehicle straight-line travelling solves the problems, such as that four wheels are the bad control of flat-plate trolley direction of advance of universal wheel, from
And realize the quantity according to actual use situation adjust automatically universal wheel, so as to being capable of tablet hand easy to use in the case of various
The technique effect of cart effectively solves current flat-plate trolley and there are problems in actual use, and practicability is good；Extremely
In how setting program make PLC16 automatically control electromagnetic brake 4, driving motor 8, linear motor 9 action belong to existing programming
Technology is not necessarily to repeat herein.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
