A kind of automated guided vehicle with hoistable platform
Technical field
The present invention relates to automated guided vehicles, more particularly to a kind of automated guided vehicle with hoistable platform.
Background technique
AGV is the abbreviation of (Automated Guided Vehicle), implies that " automated guided vehicle ", refers to and be equipped with
Electricity magnetically or optically waits homing guidances device, it can be travelled along defined guide path, has safeguard protection and various transfers
The transport vehicle of function.It is existing to be used for transferring containers automated guided vehicle, do not have hoistable platform usually, in container
In transport process, after needing that dedicated container lifting device is waited to remove the container on transport vehicle, or with dedicated liter
After drop AGV companion cooperates completion to unload case, it can be just transferred to subsequent work, working efficiency thus greatly reduces, and using liter
It is also very high to drop AGV companion cost, is difficult to meet the needs of existing automatic dock.
Summary of the invention
The object of the present invention is to provide a kind of automated guided vehicle with hoistable platform, lifting mechanism can be held in the palm
Play or put down container on transport vehicle, when loading and unloading container is more convenient, avoids the waiting time of loading and unloading container, greatly
Big improves work efficiency.
In order to solve the above technical problems, the present invention adopts the following technical scheme that:
A kind of automated guided vehicle with hoistable platform, including vehicle ontology, vehicle ontology are equipped with loading carriage, carrying
The two sides of vehicle frame are equipped with the first limiting bracket, and the middle part of loading carriage is equipped with hoistable platform, and vehicle ontology is equipped with lifting cylinder, rise
The piston rod of drop oil cylinder is connected with hoistable platform, and the both ends of hoistable platform are equipped with the second limiting bracket.
In a kind of automated guided vehicle with hoistable platform above-mentioned, it is equipped at the first limiting bracket on loading carriage
First dropping place decision mechanism, the second dropping place decision mechanism is equipped on hoistable platform at the second limiting bracket, the first dropping place judges machine
Structure, the second dropping place decision mechanism and lifting cylinder are connected with the control system of vehicle ontology, and control system and warning device are electrically connected
It connects.
In a kind of automated guided vehicle with hoistable platform above-mentioned, it is additionally provided with pilot sleeve on vehicle ontology, is oriented to
Sleeve is fixed on the vehicle frame of vehicle ontology, and guide rod is equipped in pilot sleeve, and guide rod is located at the lower section of hoistable platform, guide rod
It is connected with hoistable platform.Pilot sleeve is fixedly connected with the vehicle frame of vehicle ontology, can make hoistable platform rise along the vertical direction or
Decline.Since container has biggish weight, add after pilot sleeve and guide rod can reduce hoistable platform it is lateral by
Power prevents container tilt.
In a kind of automated guided vehicle with hoistable platform above-mentioned, the first limiting bracket and the second limiting bracket
Bottom is equipped with slot position, is equipped with reset spring in slot position, one end of reset spring is connected with the inner wall of slot position, the other end and Che Ben
Body is connected.Reset spring is in elongated condition, there is horizontal pulling force to the first limiting bracket and the second limiting bracket.Work as needs
When container is placed on transport vehicle, hoistable platform is in non-elevated state, if container position is not accurate enough, falls in
On the inclined surface of one limiting bracket or the second limiting bracket, limiting bracket can generate lateral pulling force, this pulling force can overcome reset
The pulling force of spring makes limiting bracket generate lateral displacement, container is enable smoothly to be placed on transport vehicle.
In a kind of automated guided vehicle with hoistable platform above-mentioned, it is additionally provided with lead screw in slot position, is set on vehicle ontology
There is silk cylinder, one end of lead screw is set in silk cylinder, and the other end is set in reset spring, and lead screw is equipped with first gear;Che Ben
Driving motor is also equipped on body, the output shaft of driving motor is equipped with second gear, second gear and first gear engagement.When
When needing to be placed on container on transport vehicle, hoistable platform is in non-elevated state, and driving motor drives first gear rotation,
First gear drives second gear rotation, and second gear drives lead screw rotation, the interior screw thread being equipped with and lead screw is adapted of silk cylinder, energy
So that lead screw is generated axial movement, overcomes the elastic force of reset spring, limiting bracket is made to extend outwardly, expand the receiving plane of transport vehicle
Product.After container is put well, driving motor is rotated backward, under the action of driving motor and reset spring limiting bracket restore to
Initial position.
In a kind of automated guided vehicle with hoistable platform above-mentioned, lead screw is equipped with limited block, reset spring
One end is welded on limited block.Driving motor is connected with the control system of vehicle ontology.
In a kind of automated guided vehicle with hoistable platform above-mentioned, set on vehicle ontology there are two hoistable platform, two
A hoistable platform is located at the both ends of vehicle ontology.Two hoistable platforms work independently, and complete the loading, unloading of container, thus
Improve the transfer efficiency of automated guided vehicle.
In a kind of automated guided vehicle with hoistable platform above-mentioned, the piston rod and hoistable platform ball of lifting cylinder
Head is hinged, and rodless cavity end and loading carriage use pin shaft joint.Bulb hinged can discharge lifting cylinder and couple with hoistable platform
Freedom degree, can to avoid lifting cylinder bear hoistable platform on unbalance loading, excessive eccentric wear is caused to lifting cylinder sealing element, is drawn
It is let out in lifting oil cylinder.
Compared with prior art, automated guided vehicle of the invention is equipped with hoistable platform, and lifting cylinder is able to drive
Hoistable platform rises or falls, to hold up, put down container on hoistable platform.Also, on loading carriage and hoistable platform
It is equipped with dropping place decision mechanism, when the position of container can not prompt user by warning device at that time.
