Technical Field

The invention relates to the field of automobile carrying and the field of vehicle-mounted jacks, in particular to a wheel lifting and translating device.

Background

Along with the popularization of the trolley, the phenomenon of illegal parking is increased; meanwhile, in areas with heavy rain or near water, the water level rises due to heavy rain, flood tide and the like, so that the cars are submerged, and particularly in parking lots with drainage capacity not meeting the requirements of heavy rain, the cars are soaked more commonly.

The existing car mover has three problems: firstly, the function of greatly improving the height of the wheel above the ground is not realized, and the vehicle can only be lifted a very small distance away from the ground; secondly, the manufacturing cost is higher: the hydraulic cylinder type vehicle mover requires high machining precision of parts due to sealing requirements, the non-hydraulic cylinder type vehicle mover is complex in structure, and both the hydraulic cylinder type vehicle mover and the non-hydraulic cylinder type vehicle mover cause high production and maintenance cost and are not beneficial to popularization; when the vehicle is moved for use, each wheel needs one set of vehicle moving device, and the vehicle moving device cannot be used independently, so that the vehicle moving cost is high.

The existing portable jack is mature, but does not have the function of moving the vehicle and the function of stably storing and preventing water after the vehicle is lifted to a larger height.

Disclosure of Invention

In order to solve the problems, the technical scheme of the invention is as follows:

a wheel lifting and translating device comprises an underframe, a lifting mechanism and a U-shaped frame.

The underframe is composed of a cross beam and two supporting beams, and the supporting beams are connected to two ends of the cross beam to form a U-shaped or H-shaped structure.

And rollers are respectively arranged below the end parts of the two supporting beams.

The lifting mechanism is arranged on the cross beams of the bottom frame and consists of 4 connecting rods which are hinged with each other, and nuts and screws which are arranged on the hinged shafts. 4, connecting rods are connected end to form a parallel rhombus structure, when the connecting rod is placed in a working state, one of two middle articulated shafts is fixedly connected with a nut, the other middle articulated shaft is connected with a screw rod, and the two articulated shafts can only rotate relatively; the screw rod and the nut are connected together through threads; when the screw rod is rotated, the screw rod and the nut respectively drive the two middle hinged shafts to open and close, so that the lifting mechanism is lifted.

The upper part of the lifting mechanism is connected with a U-shaped frame, and the direction of the opening of the U-shaped frame is consistent with that of the opening of the bottom frame.

When the device is used, the U-shaped frame is adjusted to a low position, the opening is opposite to the side surface of the wheel and is translated below the wheel; when the lifting jack is used, the raised part in the middle of the U-shaped frame is placed below the vehicle lifting position; the screw lifting mechanism is rotated to drive the U-shaped frame to support the vehicle.

Compared with the prior art, the invention has the beneficial effects that:

the device has the functions of moving the vehicle, lifting jacks and preventing water from being soaked, and can move the vehicle and lift the vehicle to increase the ground clearance and prevent water from being soaked; and this device cooperates general saddle or cushion can singly set independent use, does not need 4 sets to cooperate the use, compares and moves the current situation that the car can only be moved in 4 sets of cooperation industries of car ware, and this device use cost is extremely low. The device has simple structure, reliability, practicability, easy maintenance and carrying and easy popularization.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention.

Referring to fig. 1, 2 and 3, the wheel lifting and translating device of the present invention includes an underframe 1, a lifting mechanism 2, a U-shaped frame 3 and a roller 4.

The underframe 1 is composed of a first supporting beam 101, a cross beam 102 and a second supporting beam 103, wherein the first supporting beam 101 and the second supporting beam 103 are respectively welded at two ends of the cross beam 102 and fixedly connected into an H-shaped or U-shaped structure.

Rollers 4 are respectively mounted below both ends of the first support beam 101 and the second support beam 103.

The cross beams 102 are provided with lifting mechanisms 2, and each lifting mechanism 2 is composed of a first connecting rod 202, a second connecting rod 204, a third connecting rod 207, a fourth connecting rod 210, an upper hinge shaft 201, a first middle hinge shaft 203, a second middle hinge shaft 208, a lower hinge shaft 206, a screw 205 and a nut 209. The lower hinge shaft 206 hinges the second connecting rod 204 and the third connecting rod 207 with the cross beams 102; the first connecting rod 202 and the second connecting rod 204 are hinged together by a first middle hinge shaft 203, and the screw 205 is fixed on the first middle hinge shaft 203 and can only rotate relatively; the second middle hinge shaft 208 hinges the third connecting rod 207 and the fourth connecting rod 210 together, and the nut 209 is fixed on the second middle hinge shaft 208; the screw 205 and the nut 208 are screwed together; the upper hinge shaft 201 hinges the first connecting rod 202 and the fourth connecting rod 210 with the U-shaped frame 3; the opening and closing of the first middle hinged shaft 203 and the second middle hinged shaft 208 can be realized by rotating the screw rod 205, and the lifting of the upper hinged shaft 201 can be realized under the condition that the lower hinged shaft 206 is fixed, so that the lifting of the U-shaped frame is driven.

In this embodiment, as shown in fig. 4 and 5, the device is moved from the side to the lower part of the wheel along the ground, the wheel is placed in the opening of the U-shaped frame, the screw rod is rotated, and the U-shaped frame is lifted to support the wheel off the ground. After each wheel of the vehicle is supported by one set of the device, the vehicle can translate; can also be used with a universal slide carriage or a block: after the wheels are lifted to a certain height, the universal slide carriage or the block-up block is placed below the wheels and then the device is lowered and taken out, other wheels are operated in the same way, the effect of translation and storage at a larger height above the ground can be realized by the method, and the cost is lower when the universal slide carriage or the block-up block is matched with the device. When the device is used as a jack, as shown in fig. 6, the upper part of the U-shaped frame 3 is raised and placed below the jacking point of the vehicle, and the vehicle can be lifted by rotating the screw rod.

On the basis of the embodiment, those skilled in the art can change it appropriately, and all or part of the functions of the present invention can also be implemented, for example:

1. the underframe 1 can adopt a split structure and is movably connected together so as to be convenient for size adjustment and carrying;

2. the vehicle lifting function can be realized when the roller 4 is not arranged below the underframe 1;

3. the lifting mechanism 2 can be realized by adopting a hydraulic jack;

the U-shaped frame 3 can be realized by adopting a split structure with adjustable space or hinged connection.

Such variations are intended to fall within the scope of the claimed invention.
