Vehicle-mounted operation type tyre disassembling and assembling machine

Abstract

The invention provides a vehicle-mounted operation type tyre disassembling and assembling machine, which comprises a machine body, wherein a center upright post is mounted on the machine body; a cantilever is matched with the center upright post in a sliding fit way; and the cantilever is provided with a lifting sleeve which is fixed relative to the center upright post by a locking structure. The vehicle-mounted operation type tyre disassembling and assembling machine is characterized in that the cantilever comprises a rear cantilever and a front cantilever; the rear cantilever is rotatably connected to a cantilever support pillar; the front cantilever and the rear cantilever are connected by a first connecting sleeve; the front of the rear cantilever is provided with a pivot which is vertical to the axis of the cantilever; the front section of the rear cantilever and the rear section of the rear cantilever are rotatably connected by virtue of hinge joint of the pivot; a tyre disassembling pawl is arranged on the front cantilever; and the tyre disassembling pawl penetrates and sleeves the front cantilever in a slidable way through a second connecting sleeve. An operator can easily realize the disassembly and assembly between tyres of various models and a hub by virtue of the vehicle-mounted operation type tyre disassembling and assembling machine; the use is convenient and flexible; space is saved; and the machine can be conveniently and flexibly used in a narrow carriage.

Description

technical field [0001] The invention relates to a tire replacement device, in particular to a vehicle-mounted operation type tire changer. Background technique [0002] The maintenance of automobiles is related to the safety of people's lives. As one of the most important parts of automobiles, the maintenance of tires is especially important. Car tires need to be repaired or replaced after being used for a period of time. At this time, the tires need to be separated from the wheel hub. If on-site maintenance or emergency rescue tires are repaired on the spot, it is necessary to use a car to transport the tire changer to the scene for maintenance. Disclosed a kind of tire changer as Chinese invention patent CN204109707U, during work, its cantilever 5 is supported by lifting fixed shaft 6, and lifting fixed shaft 6 passes tire, and tire is fixed by tire clamping plate 3, but when tire completes tire removal When taking off from the lifting fixed shaft 6 or when placing tires...

Problems solved by technology

Disclosed a kind of tire changer as Chinese invention patent CN204109707U, during work, its cantilever 5 is supported by lifting fixed shaft 6, and lifting fixed shaft 6 passes tire, and tire is fixed by tire clamping plate 3, but when tire completes tire removal When taking off from the lifting fixed shaft 6 or when placing tires to penetrate the lifting fixed shaft 6, the cantilever 5 must be removed from the upper end of the lifting fixed shaft 6. Because the cantilever 5 is heavier, the labor intensity of the operator is increased. Moreover, the work efficiency is reduced, and the operation is inconvenient; in addition, the general compartment is relatively small, and it is very inconvenient if the equipment is operated on the vehicle, especially some larger tires cannot be operated on the vehicle, but if the equipment is unloaded It is time-consuming and labor-intensive, so it is necessary to design a vehicle-mounted tire changer that takes up little space, is easy to use, and is flexible.
