Description

Technical Field

[0001] The invention relates to a mechanical three-dimensional parking device, in particular to a split clamping and lifting type automobile transporter and a method for clamping and lifting an automobile. Background Art

[0002] With the rapid development of economy and the increasing number of cars, the parking problem in large and medium-sized cities has become more and more prominent. In recent years, large-scale plane moving mechanical parking equipment and vertical lifting mechanical parking equipment have developed rapidly. Plane moving mechanical parking equipment and vertical lifting mechanical parking equipment generally include equipment such as car entry room, elevator, horizontal moving trolley and intelligent transport trolley. Among them, the intelligent transport trolley is the core equipment of the intelligent garage, which completes the task of transferring the car between the parking space and the horizontal moving trolley. At present, the intelligent transport trolley in the intelligent three-dimensional parking garage is composed of two front and rear trolleys. The front trolley is responsible for clamping the front wheel pair of the car, and the rear trolley is responsible for clamping the rear wheel pair of the car. A pair of clamping arms on the trolley, driven by the clamping motor and the transmission gear, forcibly clamp the tires of the front and rear wheels of the car through rotation, extension and clamping, so that the entire car leaves the parking surface and is transferred to the two intelligent transport trolleys. This car transfer method of forcibly clamping the tires of the car by the clamping arm is easy to cause damage to the vehicle tires, especially when the tire pressure is insufficient. When the wheel is clamped, it is easy to cause the accident of the tire being pinched and bursting. In order to solve this problem, technicians in the same field have been trying to change the "forced clamping and lifting" action mode of the clamping arm to completely eliminate the lateral force of the clamping arm on the tire. The Chinese patent with publication number CN110056228 discloses a clamping and lifting type car transporter. This technical solution decomposes the existing clamping arm's forced clamping and lifting action of the wheel into two actions of "clamping" and "lifting". After the clamping motor drives the clamping arm to rotate horizontally, it touches the wheel wheel. When the tire is under, it stops immediately, and then, relying on the lifting platform structure arranged on the trolley, the clamping arm and the vehicle body are lifted up to leave the parking surface, so as to realize the transfer of the vehicle between the parking space and the transport trolley; the lifting platform arranged on the transport trolley of this technical solution is completed by using four ball screws, which can achieve high-precision lifting, but have the characteristics of high cost and high requirements for working clean environment, and are not suitable for use in the garage field. At the same time, there are also defects such as poor synchronization of the four screws, easy to get stuck, and complicated installation, maintenance and overhaul.

[0003] Since the transport trolley clamps the wheel tire by the rotation of the clamping arm, the clamping arm is made of steel plates. The hard clamping arm, driven by the motor, rotates and contacts the rubber tire to complete the clamping, which will definitely damage the rubber tire. How to overcome this problem? Technical personnel in the existing field generally use mechanical limiters and other means to reduce the clamping impact of the clamping arm on the tire, but these technical measures have difficulties in mechanical structure installation and adjustment, and cannot achieve the effect of flexible clamping.

[0004] The car transporter enters from under the car chassis, and after the clamping arm on the transporter rotates and extends, it clamps the four wheels of the car and lifts it up to achieve car transfer; the heights of existing car chassis are different. When the transporter enters the bottom of the car with a lower chassis, the car chassis is easily scratched, and even the transporter and the car chassis are stuck together, making it impossible to store and retrieve the car, and troubleshooting is required. How to avoid these phenomena is also a problem that needs to be solved on site. Summary of the invention

[0014] A method for clamping and lifting a car using a split clamping and lifting car transporter, characterized by the following steps:

[0015] The first step is to set a front intelligent transport trolley and a rear intelligent transport trolley on the longitudinal moving guide rail of the transport trolley arranged on the transverse moving trolley, and park cars on the front wheel frame and the rear wheel frame of the parking space;

[0016] Step 2: When the lateral transport trolley moves to one side of the car and the longitudinal moving guide rail of the transport trolley is aligned with the lateral introduction transport trolley plate, the front intelligent transport trolley first drives to the front wheel pair of the car, and then the rear intelligent transport trolley drives under the chassis of the car and docks with the front intelligent transport trolley;

[0017] Step 3: The front arm drive motor and the rear arm drive motor on the front intelligent transport trolley are operated simultaneously, so that a pair of front arms and a pair of rear arms are opened simultaneously to clamp the front wheel pair of the car;

[0018] Step 4: Control the front arm drive motor on the rear intelligent transport trolley to rotate and open the pair of front arms, then start the trolley travel drive motor on the rear intelligent transport trolley to make the rear intelligent transport trolley move backwards. When the pair of front arms on the rear intelligent transport trolley touch the rear wheels of the car, the rear intelligent transport trolley stops moving, and the rear arm drive motor controls the pair of rear arms to open, and the pair of front arms and the pair of rear arms clamp the rear wheels of the car.

[0019] Step 5: Start the lifting platform drive motor to raise the lifting platform. The lifting platform on the front intelligent transport trolley and the lifting platform on the rear intelligent transport trolley jointly lift the car away from the front and rear wheel frames of the parking space.

[0020] Step 6. Start the travel drive motor on the front intelligent transport trolley and the travel drive motor on the rear intelligent transport trolley at the same time. The front intelligent transport trolley and the rear intelligent transport trolley carry the car and drive it onto the transverse trolley to complete the transfer of the car from the parking space to the transverse trolley.

[0021] The method of a split clamping and lifting car transporter is characterized in that in the fourth step, the rear intelligent transport trolley moves backward, and when a pair of front arms on the rear intelligent transport trolley approaches the rear wheel pair of the car, the contact rod on the long strip clamping plate of the arm protrudes from the long strip hole, and first contacts with the rear wheel tire of the car. As the rear intelligent transport trolley moves backward, the contact rod compresses the left swing rod supporting spring through the left L-shaped swing rod and the right L-shaped swing rod, so that the contact rod and the rear wheel tire are flexibly contacted. When the contact rod is about to enter the long strip hole where the contact rod protrudes, the middle L-shaped swing rod contacts the contact contact of the tire contact detection switch, and the tire contact detection switch sends a signal to cut off the power supply of the trolley travel drive motor on the rear intelligent transport trolley, and the rear intelligent transport trolley stops moving backward. Then, the rear arm driving motor controls the pair of rear arms to open, and the pair of front arms and the pair of rear arms clamp the rear wheel pair of the car.

[0022] The present invention uses two front and rear transport trolleys with two independent power supply units. When picking up a vehicle, an ultra-low chassis detector arranged at the front end of the transport trolley is used to detect the height of the vehicle chassis. After determining that the vehicle does not have an ultra-low chassis, the two transport trolleys enter under the vehicle chassis, first clamp and find the tires, and then lift the vehicle. The front and rear transport trolleys complete the above actions independently. And by arranging a contact rod and a tire contact detection switch on the reporting arm, flexible clamping of the tires is achieved, which greatly reduces the damage of the clamping arm to the vehicle tires. The two transport trolleys used in the present invention enter under the chassis of the pre-taken vehicle at the same time, and then the rear trolley opens the front clamping arm and moves backward to find the tires that contact the rear wheels of the vehicle. Finally, the clamping method of the rear trolley opening the rear clamping arm is more conducive to the accurate clamping of the rear tires of vehicles with different wheelbases by the transport trolley, which greatly improves the work efficiency.
