Detailed Description

Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.

The utility model provides a roadway parking AGV, which comprises a master car and a slave car. The main vehicle comprises a basic frame 1, a lifting platform 2 and a supporting frame 5.

The base frame 1 comprises four longitudinal beams 11, two transverse beams 12 and four upright posts 13. Four upright posts 13 are respectively arranged at four corners of the rectangle, and two cross beams 12 and two longitudinal beams 11 are respectively and fixedly connected with the bottoms of the four upright posts 13 to form the rectangle. The other two longitudinal beams 11 are fixedly connected with the tops of the upright posts 13. That is, there is no cross beam 12 at the top of the upright 13 and no lateral restraint.

The upright post 13 is provided with a driving device for driving the lifting platform 2 to lift. The driving device comprises a motor 31, two sets of chain wheels 32, a chain 33. The upright 13 is hollow and is provided with a notch for passing the chain 33 up and down, respectively. Each set of sprockets 32 comprises two sprockets and is disposed inside and outside the upright 13, respectively, while the sprockets 32 are rotatably coupled to the upright 13. The motor 31 is fixed to the bottom outer side wall surface of the column 13, but its output shaft extends into the column 13 and is connected to the sprocket 32. Both ends of the chain 33 are fixedly connected with the lifting platform 2.

The lifting platform 2 is provided with two beams and is respectively positioned at two opposite sides of the two beams 12. Each lifting platform 2 corresponds to two chains 33. The lifting platform 2 is U-shaped and is used for placing and fixing the supporting frame 5. The elevating platform 2 is provided with a protrusion 21 at both ends thereof, respectively. The projection 21 is used for welding the fixing chain 33 on the one hand and for welding the fixing support plate 41 on the other hand, the support plate 41 being in sliding connection with the upright 13. When the four motors 31 are operated synchronously, the lifting platform 2 can be driven to lift.

A base plate 44 is arranged on the upright 13, and two vertical slide rails 43 are fixedly arranged on the base plate 44, so that a space is reserved between the slide rails 43 and the upright 13. Two sets of pulleys 42 are rotatably arranged on the supporting plate 41, and three pulleys 42 are arranged in each set. The two sets of pulleys 42 are respectively positioned at the left side and the right side of the two sliding rails 43, the pulleys 42 are V-shaped grooved wheels, and the sliding rails 43 are matched with the pulleys 42. The current pulley 42 and the sliding rail 43 can provide sufficient constraint for the lifting platform 2, so that the lifting platform 2 can only move up and down, and therefore, the two lifting platforms 2 serve as 'beams' of the two upright posts 13, and can apply transverse constraint to the two upright posts 13, so that the rigidity of the whole foundation frame 1 is improved.

The support frame 5 is used to carry a slave vehicle. The slave vehicle is a prior art product, such as a pinch wheel type automobile carrying robot 6 disclosed in the publication No. CN 205654151U.

By the actuation of the motor 31, the support frame 5 can be lifted up to the two floors of the stereo garage, so that the slave vehicle can directly drive into the two floors and transport the vehicle.

In the scheme, the lifting platform 2 drives the supporting frame 5 to lift, so that the lifting of the slave car is realized. Since the driving means, the pulleys 42 and the slide rails 43 are arranged on both sides of the support frame 5, the support frame 5 can reach a relatively lower position, facilitating the entry of a vehicle from a garage onto the support frame 5. In-process lift platform 2 plays the effect of providing horizontal restraint to stand 13, and has saved crossbeam 12 at stand 13 top, has saved the material, does not hinder the up-and-down motion of braced frame 5 simultaneously, then braced frame 5's length just can adjust to more easily dock with garage two-layer moreover.

In this embodiment, the support frame 5 is abutted against the parking stand 8 through the lock mechanism 7. The parking stand 8 includes a plurality of support columns 81 and support platens 82. The support column 81 is vertically fixed to the garage floor. Support tables 82 are fixedly arranged at the top and the bottom of the support column 81, and the two layers of support tables 82 correspond to one layer and two layers of the garage respectively. The support frame 5 can be docked with both the support platen 82 of one layer and the support platen 82 of two layers.

The locker mechanism 7 includes a locker motor 71, a screw 72, a mount 73, a connection holder 74, a locker pin 75, a slide support holder 76, a locker roller 77, and a locker socket 83. The mounting seat 73 is fixed at the bottom of the supporting frame 5, and two ends of the screw rod 72 are rotatably connected with the mounting seat 73. The lock layer motor 71 is fixed at the bottom of the support frame 5, a main shaft of the lock layer motor 71 is fixedly connected with one end of the screw rod 72, and the lock layer motor 71 is used for driving the screw rod 72 to rotate. The screw rod 72 is in threaded fit with the connecting seat 74, the connecting seat 74 is fixedly connected with one end of the lock layer pin 75, the lock layer roller 77 is rotatably arranged at the other end of the lock layer pin 75, the lock layer pin 75 is parallel to the screw rod 72, and the lock layer pin 75 is in sliding connection with the sliding support seat 76. The lock layer socket 83 is provided at the bottom of the support platen 82. The ply roller 77 is positioned between the ply pin 75 and the ply socket 83, and the ply roller 77 is configured to be inserted into the ply socket 83.

When the motor 31 drives the screw rod to rotate, the screw rod drives the connecting seat 74 to move along the axial direction of the screw rod 72, and simultaneously drives the locking pin 75 and the locking roller 77. When the lock layer roller 77 is inserted into the lock layer socket 83, the docking of the support frame 5 with the parking platform 8 is completed. The effect of tolerance can be played in the setting of lock layer gyro wheel 77, reduces the influence of garage ground height unevenness, and lock layer socket 83 also can provide the restraint of vertical direction to lock layer gyro wheel 77 behind the lock layer gyro wheel 77 to follow the in-process that the car removed to on the support platen 82, can more stabilize the reduction jolt.
