Description

Technical Field

[0001] The utility model relates to the technical field of automobile maintenance machinery, in particular to a special lifting device for a tire changer. Background Art

[0002] Car tires are key components for car driving, and car tires are consumables. Tires that have been driving for a certain period of time need to be repaired or replaced. Tire changers are the main work equipment of most car repair departments or repair shops, especially in the northeast and northwest when it snows heavily in winter. It is the replacement season. The replacement time of conventional tires and snow tires is short and the workload is large. Because of heavy snow, snow tires must be replaced, and in spring when the ice and snow melt, they need to be replaced back to ordinary tires. Waiting in line is the norm at this time, so tire change is very urgent.

[0003] Almost all tire repair shops have tire changers, which can be used for socializing under normal circumstances, but when the weather changes suddenly, a large number of vehicles will be waiting in line. At present, most tire repair shops use ordinary tire changers, and the tires are manually moved to the tire changers and replaced by the tire changers. Some advanced tire changers are equipped with a lifting device for the tire changers, but the speed is slow, and after lifting, they still need to be manually moved to the tire changer, which is inefficient and labor-intensive, affecting the repair speed. Before changing the tire, the tire needs to be clamped with a large shovel and anvil attached to the tire changer to loosen it, but most tire changers have an anvil shovel on one side and a lifting device on the other side. It is also necessary to manually push and roll the clamped tire onto the lifting device and make a half circle along the front of the tire changer. Summary of the invention

[0004] The purpose of the utility model is to provide a special lifting device for a tire changer. In view of the above-mentioned drawbacks, the utility model cleverly arranges a crank arm and a lifting cylinder in the space between a fixed anvil and a large shovel. After the large shovel and the fixed anvil are clamped, the lifting cylinder is turned on to lift the tire through the crank arm. When the tire is flush with the tire changer platform, the tire is pushed onto the workbench of the tire changer, thereby reducing the rolling tire route, saving manpower, time, and gas consumption. It is the best choice to replace the old tire lifting device.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is a special lifting device for a tire changer, comprising: a crank arm, a lifting cylinder, a lifting plate and an articulated shaft. The crank arm is fixedly connected by an upper crossbeam, a vertical beam and a lower crossbeam. The lifting cylinder is vertically arranged, one end of which is hinged to the upper crossbeam of the crank arm, and the other end is hinged to the tire changer base. The other end of the lower crossbeam of the crank arm is fixedly connected to the lifting plate 1, and the other end of the upper crossbeam of the crank arm is hinged to the connecting ear at the rear of the large shovel arm of the tire changer through the articulated shaft.

[0006] The vertical beam and the upper cross beam, as well as the vertical beam and the lower cross beam are all provided with triangular reinforcing rib plates to increase the strength of the curved arm.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0008] 1. The utility model sets the crank arm and the lifting cylinder in the space between the fixed anvil and the large shovel, which reduces the rolling tire route, saves manpower and time, and is the best choice to replace the old tire lifting device;

[0009] 2. The utility model uses steam pressure to lift when lifting, and does not require steam pressure when lowering, and can manually control the lowering speed, saving steam consumption, having a good lifting effect, and being several times more efficient than existing lifting devices;

[0010] 3. The utility model is suitable for use with various types of tire changing machines.

[0011] The utility model is further described in detail below with reference to the accompanying drawings: BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model discloses a special lifting device for a tire changer, comprising: a crank arm, a lifting cylinder 5, a lifting plate 1 and an articulated shaft 7. The crank arm is fixedly connected by an upper crossbeam 6, a vertical beam 3 and a lower crossbeam 2. The lifting cylinder 5 is vertically arranged, one end of which is articulated with the upper crossbeam 6 of the crank arm, and the other end is articulated with a tire changer base. The other end of the lower crossbeam 2 of the crank arm is fixedly connected with the lifting plate 1, and the other end of the upper crossbeam of the crank arm is articulated with a connecting ear at the rear of a large shovel arm of the tire changer through the articulated shaft 7.

[0022] The vertical beam 3 and the upper cross beam 6, as well as the vertical beam 3 and the lower cross beam 2 are all provided with triangular reinforcing rib plates 4 to increase the strength of the crank arm.

[0023] Working principle:

[0024] The utility model cleverly arranges the crank arm and the lifting cylinder in the space between the fixed anvil and the large shovel. It is only necessary to cut a semicircular hole in the part of the large shovel arm corresponding to the lifting cylinder to adapt to the lifting cylinder, cleverly avoiding the clamping large shovel. First, the tire is pushed onto the lifting plate. After the large shovel and the fixed anvil cooperate for clamping, the switch of the lifting cylinder is turned on, and the tire can be quickly lifted to the height flush with the tire changer platform. The operator then pushes the tire onto the tire changer platform and proceeds to the next step.

[0025] The lift of the old-style tire changer is set on the left side of the tire changer. When the operator is working, he needs to first clamp the tire with a large shovel and a fixed chopping board on the right side of the tire changer and then roll it to the left side and place it on the lifting device. After starting the lifting operation, the lifting cylinder or air cylinder will lift the lifting frame along the axis until it is flush with the tire changer platform, and then manually move the tire horizontally to the tire changer.

[0026] The above description is only a preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present utility model can make equivalent substitutions or changes based on the technical scheme and utility model concept of the present utility model, which should be covered by the protection scope of the present utility model.
