Description

Vehicle moving device

Technical Field

The utility model relates to a move the car and use the utensil field, concretely relates to move car ware.

Background

Vehicle movers are common tools currently used for moving vehicles in the field. Four tires of the vehicle are respectively fixed through the four vehicle moving devices, and the 4 universal wheels at the bottom of each vehicle moving device are utilized, so that the supported vehicle can move forwards, backwards and rotate for 360 degrees, and the device has the characteristics of flexibility, convenience, simple operation, safety, reliability and the like.

The utility model patent of application number 201920526277.6 discloses a portable car ware that moves belongs to car removal technical field, including screw rod telescopic machanism and folding supporting mechanism, be equipped with the circular walking beam rather than sliding fit in the circular fixed beam, the one end of circular fixed beam is provided with a supporting beam one perpendicularly, the one end of circular walking beam is provided with a supporting beam two perpendicularly, the both ends of supporting beam one and a supporting beam two are the vertical universal wheel three and the universal wheel four of being provided with respectively, the middle part of a supporting beam one and a supporting beam two is provided with the guide ring.

Above-mentioned patent rotates through the screw rod and realizes the flexible between circular fixed beam and the circular walking beam, nevertheless draws close the in-process that carries out the lifting to the tire between two supporting beam, and the tire can make two supporting beam receive outside detached power to circular walking beam can stimulate the screw rod rather than being connected, makes the part on the screw rod exist and the circular fixed beam between the condition of laminating contact. Because the vehicle is very heavy for the outside detached power that receives on two supporting beams can be very big, thereby leads to laminating contact between the part on the screw rod and the circular fixed beam closely, has increased frictional force between the two, and then has increased the pivoted degree of difficulty of drive screw, influences the operating efficiency of car shifter.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a move car ware, this move car ware can reduce the frictional resistance that receives when drive screw rotates for labour saving and operation has reduced drive screw and has carried out the pivoted degree of difficulty.

The utility model provides a technical scheme that above-mentioned problem adopted is:

the utility model provides a car mover, including coupling beam and two supporting beams that set up on the coupling beam that have extending structure, the coupling beam is including inserting the roof beam and cup jointing the roof beam, the grafting roof beam is inserted and is located on the cup jointing roof beam, all install the universal wheel on the both ends of supporting beam's bottom surface, it is connected with the screw rod to cup joint to rotate on the roof beam, the grafting roof beam is located on the inner of screw rod with screw-thread fit's mode cover, the outer end of screw rod exposes outside the cup jointing roof beam, be fixed with on the outer end of screw rod and receive external force drive to realize pivoted connecting piece, the cover is equipped with antifriction bearing on the screw rod, antifriction bearing is located the connecting piece and cup joints between the roof beam, when antifriction bearing presss from both sides tightly between cup jointing roof beam and connecting piece, outer loop and inner ring on the antifriction bearing receive respectively by the cup jointing roof beam, the ascending power of screw rod axial direction is applyed to inner ring and outer loop on the connecting piece by the cup jointing roof beam, the connecting piece respectively.

During the use, when two supporting beam lift the tire, because grafting roof beam pulling screw rod and the condition that antifriction bearing was pressed from both sides between the connecting piece and the beam of cup jointing appears, only support antifriction bearing's inner ring or outer loop through the connecting piece and rotate when the connecting piece rotates, and the inner ring or the outer loop that the connecting piece supported do not contact with the beam of cup jointing for the contact between connecting piece and the beam of cup jointing becomes rolling contact by the face contact, and then has reduced the drive screw and has carried out the pivoted degree of difficulty, has ensured the availability factor of car shifting ware.

As a further improvement of the above technical solution, the left end of the inner ring is exposed outside the left end of the outer ring, and the right end of the inner ring is located in the hollow space of the outer ring. When the rolling bearing is clamped between the connecting piece and the sleeve-joint beam due to the fact that the plug-joint beam pulls the screw rod, the sleeve-joint beam butts against the left end of the inner ring, the connecting piece butts against the right end of the outer ring, and the left end of the outer ring is not in contact with the sleeve-joint beam, so that the connecting piece and the sleeve-joint beam are in a rolling contact state through the rolling bearing, and the rotating efficiency of the driving screw rod is guaranteed.

As a further improvement of the above technical solution, a pin groove is formed in a side surface of the outer end of the screw rod, a bayonet lock is inserted into the pin groove, a top end of the bayonet lock is exposed out of the pin groove, the connecting member is in a hexagonal tubular structure, a clamping groove for allowing the top end of the bayonet lock to be inserted in an axial direction of the connecting member is formed in an inner wall surface of the connecting member, and a first limiting member for preventing the connecting member from being separated from the outer end of the screw rod is fixed to the outer end of the screw rod. Through the setting of bayonet lock and draw-in groove to realize fixing between connecting piece and the screw rod, ensured to carry out driven effect to the screw rod, compact structure just does benefit to and carries out dismantlement formula change to the connecting piece.

As a further improvement of the technical scheme, the supporting beam is rotatably connected with a first roller and a second roller, the first roller is positioned right above the supporting beam, the second roller is positioned obliquely below the supporting beam, and the second roller is positioned between the two supporting beams. The arrangement of the first roller and the second roller is beneficial to reducing the friction between the support beams and the tire, so that the damage of the support beams to the tire is reduced in the process of lifting the tire by the two support beams close to each other.

As a further improvement of the technical scheme, the sealing end of the sleeve beam is penetrated and fixed with a sliding bearing, the sliding bearing is sleeved on the screw rod, and a second limiting part for preventing the screw rod from being separated from the sealing end of the sleeve beam is fixed on the screw rod. Through the setting of slide bearing and second locating part, do benefit to guarantee screw rod pivoted smoothness nature and stability.

As a further improvement of the above technical scheme, the sealing end of the insertion beam is penetrated and fixed with a socket piece, and the socket piece can be sleeved on the screw rod in a thread fit manner. Through the arrangement of the socket joint piece, the socket joint piece can be maintained in a replacement mode when the threads on the socket joint piece are damaged, so that the utilization rate of the plug-in beam is guaranteed, the maintenance cost is reduced, and the resource waste is avoided.

As a further improvement of the technical scheme, the top surface of the sleeve beam is provided with the observation port, so that a user can conveniently check the connection condition between the screw rod and the sleeve beam, and the assembly of the vehicle shifter is facilitated.
