Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described:
As shown in Figure 1, this vehicle-containing exchanges that car carrying robot 2 comprises main body of vehicle frame 21, the vehicle-containing elevating mechanism be installed in main body of vehicle frame 21, be installed on vehicle-containing elevating mechanism other omnibearing ambulation driving mechanism, control system 28, electric supply installation, preferably can also comprise guider, safety detection device etc.
The vehicle-containing elevating mechanism of this transfer robot comprises the lifter plate 22 and hydraulic drive mechanism that are installed on main body of vehicle frame two ends, wherein hydraulic drive mechanism also can be replaced spiral lift or price scissors hoist or electric pushrod, and hydraulic drive mechanism comprises the lifting guide pillar 23 be connected with hydraulic pump 24 and lifter plate 22.
The guider of this transfer robot comprises the laser navigation module (not shown) being installed on main body of vehicle frame one jiao, and this module also can be magnetic nail navigation module or electromagnetic navigation module or inertial navigation module, especially gyroscope.
The principle of laser navigation module is: in the space of transfer robot motion, be placed with multiple handmarking (as reflection sticker), robot in the process of walking, its laser navigation module measures the Distance geometry angle of each reflecrtive mark by the laser beam launched and be reflected back, then calculated the positional information of self by geometry, thus carry out position navigation.
The electric supply installation of this transfer robot comprises the battery 25 be installed in main body of vehicle frame and the charging mechanism 26 be connected with storage battery, the charging inlet that charging mechanism is connected with external power source is positioned on the bottom surface of main body of vehicle frame, realizes automatic charging in the charge position of transfer robot on parking floor of stereo garage.
The charging flow of electric supply installation is divided into two kinds: one is fast charge mode: when transfer robot detects that its voltage is not enough, walk to charging zone, be full of fast with high electric current, transfer robot leaves charging zone; One shallowly fills shallow mode playback: transfer robot charges to rest area at every turn, no matter voltage levels all arrives charge point.
The safety detection device of this transfer robot comprises the laser anti-collision module (not shown) being installed on main body of vehicle frame edge, this module also can be mechanical crashproof module or infrared anti-collision module or ultrasonic anti-collision module, scans the object on transfer robot all around four direction, identifies.
The operating principle of laser anti-collision module is: laser anti-collision module Emission Lasers bundle, irradiate object around, carried out the presence or absence of cognitive disorders thing by the reverberation of exploring laser light bundle, and to control system feedback signal, so that control system sends instruction, the advancing and stop of control.
As shown in Figure 2, the hoofing part mechanism of this transfer robot comprises driving wheel, is preferably 4 and drives wheels 27.
As shown in Figure 3, the control system 28 of this transfer robot by master controller and the walking module be electrically connected with master controller, be elevated module, guide locating module, security module, power supply and charge management module, communication module, human-computer interaction device to form.Wherein, walking module comprises 4 differential modules, controls respectively 4 driving wheel groups; Lifting module is used for controlling vehicle-containing elevating mechanism; Locating module is guided to be used for guiding the travel path of transfer robot and locating; Security module collides with surrounding objects during being used for preventing transfer robot from advancing, and ensures its safety; Communication module is used for transfer robot and wireless telecommunications are carried out in outside; Human-computer interaction device is used for setting transfer robot parameter and showing the running status of transfer robot.
Introduce the workflow guiding locating module below: Upper system sends task list/walking segment table by wireless network, radio station etc., and communication module monitors these data, and stored in segment table queue.AGV takes out segment table parameter, dot information, opcode information etc. from segment table queue, realizes speed generation, point of destination is determined, carries command code order output with this.Master controller realizes position calculation, its principle is as follows: adopt two position calculators to complete accurate estimation to position and calculating, wherein master site calculator adopts dead reckoning, calculates in real time according to the positional information of last time and the theoretical orientation of kinematics model to AGV of encoder information (speed encoder, angular encoder) and car body.But, because As time goes on theoretical position can produce cumulative errors, aided solving device is therefore also needed to carry out position correction.Aided location calculator is according to the laser head/magnetic dot sensor information acquisition actual position of guider.Master controller converts velocity information to the signal of telecommunication, and be sent to turning to servo-driver and driving servo-driver of walking module, servo controller controls motor and completes walking.
As seen in figs. 5-6, which show the vehicle-containing 1 for bearing automobile.Vehicle-containing is made up of plate face 11 and suspension column 12, and plate face central authorities are provided with carries power crossbeam, and plate face is checkered steel plate.
Suspension column upper end is provided with the suspension column jack 121 be inwardly recessed, and suspension column bottom is provided with the suspension column latch 122 with projection.When vehicle-containing piling is stacked, the suspension column latch of upper strata vehicle-containing can insert in the suspension column jack of lower floor's vehicle-containing just, realizes the neat stacking of vehicle-containing.
As illustrated in figures 4 and 7, in parking tier, carrying has the transfer robot of automobile under the guiding of navigation system, can realize the action such as front, rear, left and right and pivot stud, according to certain rule by extremely idle for car carrying parking stall.Also be provided with automatic charging position in parking tier, when dolly is without task, can automatically go to charge position to supplement electricity.
The course of work applying this transfer robot Transport Vehicle is:
Bicycle parking process: after car parks on the vehicle-containing of stacking machine position, stacking machine is by vehicle-containing upwards lifting one deck platen height, transfer robot sails into bottom vehicle-containing and by vehicle-containing lifting, then vehicle-containing and car are carried to the diamond of planning by transfer robot.
To pick up the car process: after system obtains instruction of picking up the car, transfer robot drives to bottom the vehicle-containing on appointment parking space, vehicle-containing and car lifting get up by elevating mechanism, vehicle-containing and car are transported on stacking machine and then leave by transfer robot, stacking machine declines a platen height, and car can leave.
It is emphasized that above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
