Description

Fork arm for lifting vehicle by rolling friction and vehicle carrying robot

Technical Field

The utility model belongs to the technical field of intelligence is parked, a fork arm for intelligent vehicle transfer robot is related to, concretely relates to fork arm and vehicle transfer robot that utilizes rolling friction to lift up the vehicle that intelligent vehicle transfer robot used.

Background

With the increase of the popularity of household vehicles, the number of vehicles in cities is increased, but the number of parking spaces in the cities is limited, and the urban land is more and more scarce, so that the parking is increasingly tense. Along with the improvement of living standard of people, the demand for a parking mode with small floor area and high automation level is gradually increased. Adopt intelligent vehicle transfer robot to carry the parking stall with the vehicle, replace the manual work to look for the parking stall and park, can effectively increase the parking number under the same area, and also can not appear the condition of jam in the parking lot in parking or the peak season of getting the car. Such a parking system and an intelligent vehicle transfer robot are expected and favored by many people. Among them, the most important equipment is an intelligent vehicle transfer robot.

At present, intelligent vehicle transfer robots with various structures have appeared in the market, 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 the vehicle transfer robot has a small volume and flexible movement, and does not need to be modified in a field or built with large-scale equipment. After the fork arm is in contact with the tire of the vehicle, the vehicle carrying robot applies horizontal extrusion force to the tire to enable the fork arm and the tire to move relatively, so that the tread of the tire is pressed on the upper surface of the fork arm, namely the fork arm supports the tire, and the effect of lifting the vehicle is achieved.

However, in use, the fork arms adopted on the existing vehicle transfer robot find that the common fork arms need larger force to lift the vehicle, even can not lift some vehicles with larger front and rear counterweight differences or heavier vehicles, and simultaneously have the possibility of clamping and bursting tires. This is because there is friction between the yoke and the tire and there is a significant height difference between the yoke and the ground. The tire needs to overcome the friction between the yoke and the tire and to overcome the height difference between the yoke and the ground so as to press on the yoke. As the weight of the vehicle increases, the greater the pressing force required for the process of lifting the vehicle. When the required squeezing force exceeds the maximum force that the drive means can provide, the yoke cannot lift the vehicle. Meanwhile, as the pressing force increases, the possibility of pinching the tire to blow out also increases.

Disclosure of Invention

In view of there being above-mentioned technical problem among the prior art, the utility model aims at to current vehicle transfer robot with the yoke be difficult to lift up some heavier or the front and back counter weight differ more vehicle's problem, and have the problem with the risk of tire clamp blowing out, design one kind and utilize rolling friction to lift up vehicle transfer robot with yoke and vehicle transfer robot of vehicle.

The utility model discloses a technical scheme as follows:

the utility model provides an utilize rolling friction to lift up fork arm for vehicle transfer robot of vehicle, including fork arm fixed plate 1 and fork arm body 2, the one end of fork arm fixed plate 1 and fork arm body 2 links to each other perpendicularly.

All the first longitudinal supports 9 and the second longitudinal supports 10 are parallel to each other, the first longitudinal supports 9 are located at the left and right sides of the rolling assembly 4, and the second longitudinal supports 10 are located at the middle of the rolling assembly 4 and are fixedly connected with the transverse supports 8. The roller shaft 6 is mounted between two longitudinal brackets. The shaft bracket 7 is fixedly connected with the wheel hub limiting seat 3 through a first longitudinal support 9.

Further, the transverse support 8 is a block structure, and one or more transverse fixing supports 11 are arranged at the bottom of the first longitudinal support 9 and the second longitudinal support 10.

Further, the shaft bracket 7 further comprises a third longitudinal bracket 12, and the third longitudinal bracket 12 is fixedly connected with the first longitudinal bracket 9.

After the rolling assembly 4 is contacted with the tire, the motor of the vehicle transfer robot drives the fork arm to continuously and horizontally extrude the tire. The rolling assembly 4 converts sliding friction with the tire into rolling friction, so that the vehicle handling robot can easily lift the vehicle. Meanwhile, as the diameter of the rolling shaft sleeve 5 is gradually reduced from inside to outside, the height difference between the fork arm body and the ground is very small, and a gentle slope exists, so that the tire can easily cross the height difference between the fork arm and the ground and climb up the gentle slope formed by the rolling assembly.

The utility model also provides a vehicle transfer robot, vehicle transfer robot installs the above-mentioned fork arm for vehicle transfer robot who utilizes rolling friction to lift up the vehicle.

The utility model discloses following beneficial effect has: the utility model discloses can easily lift up the vehicle, reduce the energy that vehicle transfer robot consumed when lifting up the vehicle. On the basis of the existing fork arm, a wheel hub limiting groove is formed in the position, corresponding to the tire, of the fork arm body, and the size of the rolling assembly in the wheel hub limiting groove is gradually reduced from inside to outside. When the fork arm contacts with the tire to promote the whole vehicle to be separated from the ground, the rolling assembly can convert sliding friction into rolling friction, the force required by the vehicle carrying robot when the vehicle is lifted is greatly reduced, the energy is saved, and the cost is reduced. And simultaneously, the utility model discloses simple structure, safe and reliable.
