The rotary limiting device comprises a ratchet wheel 7, the ratchet wheel 7 is arranged on a foot rest 5, a short steel bar 17 is arranged on a steel frame 12, a pin rod 10 is arranged on the short steel bar 7, a pull ring 11 is arranged at the tail end of the pin rod 10, a check ring is arranged at the front end of the pin rod, the short steel bar 17 is clamped between the pull ring 11 and the check ring, the head of the pin rod 10 is a guide tooth, a compression spring 15 is sleeved on the pin rod 10 between the check ring and the short steel bar 17, and the guide tooth is acted on a ratchet of the ratchet wheel 7.

The U-shaped foot rest comprises two foot rests 5 and a middle connecting body 6, wherein the first foot rest and the second foot rest are respectively in threaded connection with the connecting body 6, the ratchet wheel 7 is arranged on the middle connecting body 6, and two sides of a steel frame guide ring on the middle connecting body 6 are respectively provided with a retaining ring for limiting the front and back positions of the steel frame 12 and the U-shaped foot rest. The fixing device comprises two U-shaped clamping grooves 2, the U-shaped clamping grooves 2 are fixed at turning positions on two sides of a U-shaped foot rest, an L-shaped platform and a U-shaped buckle 16 are arranged on the U-shaped clamping grooves 2, a cam wrench 3 is arranged at the bottom of the buckle 16, the cam wrench 3 acts on the side wall of the clamping grooves 2, and the cam wrench 3 is pulled to change the groove distance of the clamping grooves 2. The outer surface of one side, close to the cam wrench 3, of the U-shaped clamping groove 2 is provided with knurls, a rubber anti-skid pad 4 is arranged in the groove of the U-shaped clamping groove 2, and arc-shaped shallow grooves are formed in two inner sides of the anti-skid pad 4 respectively. The second roller is a universal wheel with a self-locking function.

The working principle is as follows:

when the vehicle moving device is installed, the steel frame and the U-shaped foot rest are firstly rotated to be horizontal, the U-shaped buckles 16 on the two U-shaped clamping grooves 2 are taken down, and the foot rest 5 on the two sides is rotated according to the width of the U-shaped supporting foot of the battery car to adjust the corresponding distance. The fixing device is arranged on the U-shaped supporting foot of the battery car, the U-shaped supporting foot of the battery car is supported, the rear wheel of the battery car is separated from the ground, the rear wheel of the battery car is pressed down, the steel frame 12 is rotated to a proper position, and the front wheel of the battery car is separated from the ground.

When the vehicle moving device is taken down, the pull ring 11 is pulled backwards, the steel frame is lifted upwards, and the front wheel of the storage battery car is landed. The brake on the universal wheel is stepped down, and the U-shaped supporting leg of the battery car is folded to enable the rear wheel of the battery car to land. And the fixing device is taken down from the U-shaped supporting leg of the battery car.

The invention utilizes the lever structure on the original U-shaped supporting foot of the battery car to mount the car moving device at the bottom of the battery car so that the rear wheels of the battery car are separated from the ground and replaced by the universal wheels on the car moving device. The U-shaped buckles 16 can pull the two side edges of the U-shaped clamping groove 2 by pulling the cam wrench 3, so that the distance between the two side surfaces of the U-shaped clamping groove 2 is shortened, and the U-shaped supporting foot of the battery car is clamped. The anti-slip pad 4 is designed to be an arc groove, so that the friction force between the anti-slip pad 4 and the U-shaped supporting foot is increased. The contact surface of the U-shaped clamping groove 2 and the cam wrench 3 is provided with a knurl design, so that the friction force between the cam wrench 3 and the outer surface of the U-shaped clamping groove 2 is increased, and the cam wrench clamped in the work can not slip.
