Background
The three-dimensional parking equipment has been developed for over ten years since the introduction of China, and the parking is increasingly tense due to the fact that urban land is increasingly scarce. Along with the improvement of living standard of people, the demand on the stereo garage with small floor area and high automation level is gradually increased. The most important equipment in the full-automatic three-dimensional parking garage is a vehicle carrying robot. Vehicle transfer robots of various structures have appeared in the market at present, wherein the vehicle transfer robot which adopts a fork arm to clamp a vehicle tire to enable a vehicle to be separated from the ground has a wide application prospect because of small volume, flexible movement and no need of site reconstruction or large-scale equipment construction.
However, the forks used in the conventional vehicle transfer robots have been found in use that the vehicle transfer robots are inserted into the bottom of the vehicle from the side, the length of the forks of the vehicle transfer robots is greater than the width of the vehicle, and if the vehicles are parked side by side in a parking space, a large space is left beside the vehicle for the vehicle transfer robots to use when transferring the vehicles.

Moreover, the speed and the running time of the motor 33 can be adjusted to control the magnitude of alpha at will, so as to achieve the purpose of rotating the rolling direction of the wheel in any direction.
The invention further provides a vehicle transfer robot, and the telescopic fork arm is mounted on the vehicle transfer robot.
The working process of the telescopic fork arm or the vehicle transfer robot of the invention is as follows: when the vehicle transfer robot is in a state of shortening the fork arm when the vehicle transfer robot is in idle load, and the occupied space is greatly reduced when the vehicle transfer robot stops beside a vehicle. When the vehicle transfer robot stretches the fork arm into the bottom of the vehicle, the electric telescopic push rod is controlled to extend to drive the fork arm to extend, so that the fork arm can lift four tires of the vehicle simultaneously. When the fork arm moves to the part of the tire close to the ground, after the adaptive tire bracket on the fork arm contacts the tire, continuously applying extrusion force to the tire; under the action of the extrusion force, the part of the tire bracket close to the tire deflects to a certain degree towards the ground (because the front side bracket and the rear side bracket are rotationally connected, the front side bracket close to the tire can be pressed downwards, so that the front side bracket part rotates downwards by a certain angle); the tyre climbs onto the tyre bracket under the action of the extrusion force, and the deflection of the tyre bracket is partially recovered under the action of the spring, so that the tyre is separated from the ground to support the vehicle. Particularly, the outermost rolling shaft sleeve is a triangular cushion block, one fillet of the triangle can be plugged into an included angle between the tire and the ground, and compared with a circular rolling shaft sleeve, the drop between the edge of the triangle and the ground is obviously reduced. That is, the tire carrier using the triangular pad block can lift the tire off the ground more easily than the tire carrier using only the circular rolling bearing housing. Meanwhile, the diameters of the rolling shaft sleeves, which are all or far away from the transverse support, are gradually reduced along with the increase of the distance between the rolling shaft sleeves and the transverse support, so that the angle of a sharp corner extending out of the triangular cushion block is smaller, the gradient of the tire needing to climb up when the tire is lifted up is smoother, and the energy required for lifting the vehicle off the ground is further reduced.
In the working process, the tire bracket automatically deflects downwards, the height difference between the tire bracket and the ground is reduced through the deflection, the sliding friction between the tire and the tire bracket can be converted into the rolling friction through the rolling assembly, the extrusion force required by the vehicle to be separated from the ground is greatly reduced, and the risk of tire burst caused by clamping the tire is greatly reduced. When the vehicle is separated from the ground, the deflection of the tire bracket automatically restores a part under the action of the spring; when the vehicle is lowered, the deflection of the tire carrier will automatically be fully restored under the action of the spring. That is, the tire carrier of the present invention has an adaptive effect.
The invention has the following beneficial effects:
1. the fork arms are telescopic, so that the occupied space during no-load is greatly reduced, when vehicles need to be placed side by side, the vehicle carrying robot can enter the parking lot only by a small space, the vehicle carrying work is completed, and the space utilization rate of the parking lot is improved;
2. the tire bracket can deflect to the ground after contacting with the tire, so that the force required by the tire to climb onto the tire bracket is reduced, and a heavier vehicle or a vehicle with larger difference of front and rear counterweights can be easily lifted;
3. the tire bracket designed by the invention is a self-adaptive structure, and a driving device is not required to be additionally designed, so that the energy is saved, and the cost is reduced;
4. the triangular cushion block with the sharp angle is used for replacing the outermost edge rolling shaft sleeve, and the rolling shaft sleeve can be plugged into a gap between a tire and the ground, so that the tire can easily climb up a tire bracket under the assistance of a gentle slope formed by the sharp angle surface;
5. the diameters of all or a plurality of rows of the rolling shaft sleeves far away from the transverse support are gradually reduced along with the increase of the distance between the rolling shaft sleeves and the transverse support, so that the gradient on which the tire needs to climb when the tire is lifted is more gradual, and the energy required for lifting the vehicle off the ground is further reduced.
