Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and drawings.
The adjustable loading and unloading wheel cart is shown in fig. 1 and comprises a portal frame 4, horizontal L-shaped supports 8 are symmetrically arranged on two sides of a threshold 41 on the lower portion of the portal frame 4, the L-shaped supports 8 are connected with the threshold 41 in a sliding mode and can move transversely along the threshold 41, one ends, far away from the portal frame 4, of the L-shaped supports 8 face to the normal direction of the same side of the portal frame, U-shaped brackets are formed, at least two pulleys 11 are installed at the bottoms of the L-shaped supports 8 on two sides of each U-shaped bracket respectively, one opposite sides of the two L-shaped supports 8 are connected with an arc-shaped plate 10 through hinges 7 respectively, one sides, far away from the hinges 7, of the arc-shaped plates 10 are connected with movable cross rods 3 capable of moving up and down along the portal frame 4 through connecting rods 6. Two ends of the movable cross rod 3 are connected with the vertical frames at two sides of the door-shaped frame 4 in a sliding way, and two sides of the movable cross rod 3 are respectively provided with a convex column 5 of a fixed connecting rod 6.
The concave surfaces of the pair of arc plates 10 are back to the lower part of the L-shaped bracket 8. As the preferred embodiment, the threshold 41 extends to both sides to form a hollow cross bar 1, one end of the L-shaped bracket 8 is embedded in the cross bar 1, one end of the L-shaped bracket 8 embedded in the cross bar 1 is provided with bolt holes arranged at equal intervals, and the cross bar 1 is provided with corresponding positioning holes and positioning screws 12 for adjusting the distance that the L-shaped bracket 8 slides into the cross bar 1.
When the wheels are unloaded, the distance between the two L-shaped supports 8 and the locking screws 12 are adjusted only according to the size of the wheels, and then the height of the movable cross rod 3 is adjusted through the jack 9, so that the lower edge of the arc-shaped plate is located at a position close to the ground. Then the two vertical beams of the vehicle are pushed into the lower part of the wheel, and the jack is jacked up to enable the two arc plates to tightly embrace the wheel, the wheel fixing screw cap is loosened, the height of the movable cross rod 3 is adjusted to reduce the pressure of the wheel on the axle, and therefore the wheel is conveniently and integrally supported out of the axle. The wheel is pushed to a maintenance point.
When the wheels are loaded, the distance between the two L-shaped supports 8 and the locking screws 12 are adjusted only according to the size of the wheels, and then the height of the movable cross rod 3 is adjusted through the jack 9, so that the lower edge of the arc-shaped plate is located at a position close to the ground. Pushing the L-shaped support 8 under the wheel, jacking the jack to enable the two arc-shaped plates to tightly embrace the wheel, pushing the wheel under the car, adjusting the height of the movable cross rod through the jack to enable the height of the center of the wheel to be equal to the height of the center of the car, pushing the wheel into the car by the cart, and locking a wheel fixing nut.
The above detailed description of the present invention does not limit the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the scope of the claims of the present invention.
