Description

Technical Field

[0001] The utility model relates to a car transporter used in a stereo garage, in particular to a two-way traction car transporter. Background Art

[0002] Car movers originated abroad. In developed countries such as Europe and America, especially Europe, the scarcity of land resources and high labor costs have made this product have a wide range of application markets. Car movers were first used in car inspection agencies. Due to the need to move frequently in a small space, the scarcity of drivers and the need to reduce energy consumption and exhaust gas caused by low-speed operation of car engines, this product shows strong mobility and substitutability. Today, car movers can be widely used in parking lots, shopping malls, auto repair shops and 4S stores, auto manufacturers, auto inspection agencies and other industries, which can greatly improve the efficiency of on-site car transportation, save costs and be environmentally friendly.

[0003] The biggest feature of the car mover is that it can greatly reduce labor costs and make transportation easier and more efficient. It provides a solution to mechanized transportation for manually driven cars in the field. In some places where parking resources are extremely scarce, the number of cars parked can be maximized. In particular, the electric-driven car mover has the characteristics of no exhaust gas, low noise, large load-bearing capacity, small turning radius, easy and flexible operation, and high safety performance.

[0004] In an underground multi-story parking garage with an annular multi-story parking space, a lifting and rotating platform is usually arranged in the middle thereof, and a car transporter is arranged on the lifting and rotating platform to move the car to each parking space.

[0053] The utility model places the electric control device 3 in the middle of the car carrier, and the power line is led out from the bottom of the electric control device 3 and connected to the external power supply through a cable reel, so that the car carrier can be conveniently moved in the front and rear directions.

[0054] The method of using the bidirectional traction vehicle transporter described in the utility model is as follows:

[0055] 1) The car drives to the waiting area of ​​the three-dimensional parking garage, and the car carrier drives out from the turntable and reaches the bottom of the car through the control of the running position sensor;

[0056] 2) The control system controls the two clamping rod servo motors 205 in the clamping rod device 2 to rotate simultaneously. Each clamping rod servo motor 205 drives the two clamping rods 206 located on the same side of the car carrier to rotate outward 90 degrees at the same time (the initial position of the clamping rod 206 is parallel to the longitudinal direction of the car carrier, that is, in a retracted state), thereby clamping and fixing the front wheels of the car.

[0057] 3) The control system controls the comb servo motor 402 in the comb device 4 to start, so that the combs 404 and the car blocking rod 405 on both sides move outward to align the rear wheels of the car, and the combs 404 and the car blocking rod 405 stop after reaching the set position.

[0058] 4) The control system controls the driving servo motor 101 in the first driving device 1 and the second driving device 5 to start, the electromagnetic clutch 113 is closed, and the electromagnetic clutch 2 106 is disconnected; the power output by the driving servo motor 101 is transmitted to the electromagnetic clutch 113 through the driven sprocket 114, and then transmitted to the intermediate shaft 115 through the electromagnetic clutch 113. When the intermediate shaft 115 rotates, it drives the worm 112 on both sides to rotate synchronously; a screw is set on the top of the worm wheel 111 that cooperates with the worm 112 for transmission. When the worm wheel 111 rotates, the screw drives the top plate to move upward to realize the lifting action of the liftable unit and the car; then the car transporter moves the car to the turntable, and then moves it into a parking space in the three-dimensional parking garage.
