Furthermore, a lower movable frame is arranged on the outer frame in a sliding mode, and a cylinder body of the oil cylinder is arranged on the lower movable frame.

Furthermore, a stabilizing mechanism is arranged on the lower movable frame.

Further, stabilizing mean includes support and installation axle, and the support passes through the installation axle setting on the adjustable shelf down.

Further, the wheel support is in an upward arc shape.

Furthermore, the number of the oil cylinders is two, and the two oil cylinders are respectively positioned on two sides of the top of the upper movable frame.

The invention has the positive effects that: the invention uses the wheel to support the tire, and then lifts the whole body upwards through the oil cylinder, in the actual using process, the invention can be arranged outside the wheel to operate, is not influenced by the suspension space of the vehicle body, and is more convenient to operate. The angle between the two swing arms can be adjusted through the adjusting device, wheels with different diameters can be held tightly in a self-adaptive mode, and the universality is high. Meanwhile, the wheels can move laterally in the lifting process through the lateral movement of the left and right movable frames.

FIG. 2 is a schematic side view of the present invention.

Detailed Description

As shown in fig. 1 and 2, the present invention comprises an outer frame 1, an upper movable frame 2 disposed on the outer frame 1 in a vertical sliding manner through a first roller 4, a left and right movable frame 3 disposed on the upper movable frame 2 in a horizontal sliding manner through a second roller 11, two swing arms 6 having one ends rotatably disposed on the left and right movable frames 3, and a wheel support 9 disposed at the bottom ends of the swing arms 6, wherein an oil cylinder 5 is further disposed on the outer frame 1, a piston rod of the oil cylinder 5 is connected to the upper movable frame 2, sliding grooves are disposed on the left and right sides of the outer frame 1 for the upper movable frame 2 to slide in a vertical direction, and a horizontal sliding groove is disposed on the top of the upper movable frame 2 for the left and right movable frames 3.

In order to realize that the angle between the two swing arms 6 can be adjusted to be suitable for tires with different sizes, an adjusting mechanism 8 is arranged between the two swing arms 6, the adjusting mechanism 8 comprises nuts 801 correspondingly arranged on the two swing arms 6 and a screw rod 802 with two ends respectively in threaded connection with the two nuts 801, the thread directions of the two ends of the screw rod 802 are opposite, and the nuts 801 are simultaneously moved inwards or outwards by rotating the screw rod 8 to adjust the angle between the two swing arms 6.

Still slide on the outer frame 1 and be provided with down movable frame 7, lower movable frame 7 slides from top to bottom along outer frame 1, the cylinder body setting of hydro-cylinder 5 is on lower movable frame 7 be provided with stabilizing mean 10 on the lower movable frame 7, stabilizing mean 10 includes support and installation axle, and the support passes through the installation axle setting on lower movable frame 7. The number of the oil cylinders 5 is two, and the two oil cylinders are respectively positioned on two sides of the top of the upper movable frame 2. When the wheels are lifted, the stabilizing mechanism contacts the ground firstly along with the downward movement of the lower movable frame 7, and the tilting moment is overcome.

The wheel support 9 is in an upward arc shape to increase the contact area with the wheel.

The lower part of the outer frame 1 is provided with a walking wheel, and the rear part is provided with a handle, so that the whole movement is convenient.

When the invention is used, the outer frame 1 is pushed to enable the whole body to be close to the wheel, and the wheel supports 9 are positioned at two sides of the lower part of the wheel. The included angle of the swing arm 6 is adjusted by the swing arm adjusting mechanism 8 until the wheel support 9 is tightly held with the wheel. The cylinder 5 is actuated to extend. The lower mobile frame 7 first descends due to gravity, bringing the support of the stabilizing means 10 into contact with the ground, overcoming the tipping moment. The oil cylinder 5 continues to extend, the upper movable frame 2 rises, and drives the left and right movable frames 3, the swing arm 6 and the wheel support 9 to rise, so that the wheels are lifted off the ground. When the wheels move laterally, the left and right movable frames 3 can move left and right in the upper movable frame 2 to adapt to the lateral movement.

When the wheels are lowered, the operation is reversed.

The invention opens up a way for lifting the wheels at the outer side of the vehicle body, and has good operability; the wheel can adapt to wheels with different diameters through adjustment; the wheels of the heavy vehicle can be lifted due to the large lifting force; the invention can be adapted no matter what connection mode is adopted between the wheels and the vehicle body; the design has stabilizing mean, can overcome the moment of tipping, stability is good.
