Abstract
Description
Technical Field
[0001] The utility model relates to a component structure of a tire vulcanizer, in particular to a tire loading and lifting mechanism of an engineering tire vulcanizer. Background Art
[0002] The tires vulcanized in engineering tire vulcanizers are all engineering tires, bias tires or agricultural radial tires. The green tire height of these tires is high and the bladder is long when straightened, which requires the tire loading mechanism to have a high lifting height, resulting in a long cylinder rod stroke of the lifting cylinder. Therefore, the lifting cylinder is required to adopt a cylinder-in-cylinder structure. When the cylinder-in-cylinder lifting and lowering replaces the secondary rod, it will cause large vibrations to the tire loading mechanism. In addition, the cost of the cylinder-in-cylinder is high and the medium is prone to leakage. Utility Model Content
[0003] In view of the deficiencies in the prior art, the present invention aims to solve the technical problem by proposing a tire mounting and lifting mechanism for an engineering tire vulcanizing machine with a large lift and stable operation.
[0004] The tire loading and lifting mechanism of an engineering tire vulcanizer that can solve the problems of the prior art includes a lifting frame mounted on a column via a guide rail pair. The lifting frame rises and falls along the column driven by a lifting cylinder. The difference is that:
[0005] 1. The cylinder body of the lifting cylinder is installed on the column through the cylinder seat, and a pulley is installed on the cylinder rod extending upward from the lifting cylinder through the wheel frame.
[0006] 2. A steel wire rope is wrapped around the pulley, one end of the steel wire rope is connected downwardly to the lifting frame, and the other end of the steel wire rope is connected downwardly to the cylinder body or cylinder seat of the lifting cylinder.
[0007] Conventionally, a tire mounting robot is installed on the lifting frame.
[0008] Beneficial effects of the utility model:
[0009] In the structure of the tire mounting lifting mechanism of the engineering tire vulcanizer of the utility model, the operating principle of the movable pulley is utilized and the single stroke of the cylinder rod of the lifting cylinder is adopted to achieve a double lifting height of the lifting frame, i.e., the tire mounting manipulator, thereby replacing the cylinder-in-cylinder structure of the lifting cylinder in the traditional technology and having the characteristics of simple structure, stable operation and low manufacturing cost.

[0012] The technical solution of the present utility model will be further described below with reference to the embodiments shown in the accompanying drawings.
[0013] The utility model engineering tire vulcanizer tire loading and lifting mechanism includes a lifting frame 2, the left and right frame plates of the lifting frame 2 are slidably mounted on the left and right end surfaces of the column 1 through left and right guide rail pairs, and the front ends of the left and right frame plates are equipped with tire loading manipulators 8 through panels. Figure 1 shown.
[0014] The utility model also includes a lifting cylinder 3, which is vertically arranged on the front side of the column 1 and is between the left and right frame plates and the front panel. The lower end of the cylinder body of the lifting cylinder 3 (lower than the left and right frame plates) is installed on the column 1 through a cylinder seat 4. The upper end of the cylinder body of the lifting cylinder 3 is higher than the left and right frame plates and the cylinder rod of the lifting cylinder 3 extends upward. The top end of the cylinder rod is installed with a wheel frame 5, and a pulley 6 is installed in the wheel frame 5. Figure 1 shown.
[0015] The utility model also includes a wire rope 7, which is wrapped in the "V"-shaped wheel groove of the pulley 6. The lower end of the front rope body of the wire rope 7 is fixedly connected to the bottom plate extending forward from the bottom of the cylinder body through a "U"-shaped steel ring I, and the lower end of the rear rope body of the wire rope 7 is fixedly connected to the top of the left and right frame plates on the front side of the column 1 through a "U"-shaped steel ring II. Figure 1 shown.
[0016] The operation mode of the utility model is:
[0017] When the rod of the lifting cylinder 3 extends upward, the rod drives the pulley 6 to move upward, thereby driving the lifting frame 2 to rise through the rear rope body of the wire rope 7, thereby achieving the ascent of the tire mounting robot 8. According to the operating principle of the movable pulley, when the lifting height of the rod of the lifting cylinder 3 is h, the running length L of the rear rope body of the wire rope 7 is 2h, that is, the ascent height of the lifting frame 2 is 2h, thereby achieving a single lifting stroke of the rod of the lifting cylinder 3 in exchange for a double ascent height of the lifting frame 2, i.e., the tire mounting robot 8.
[0018] When the lifting cylinder 5 is depressurized, the cylinder rod of the lifting cylinder 3 is pressed down and retracted under the gravity of the lifting frame 2 and the tire mounting robot 8, and the lifting frame 2 descends, thereby driving the tire mounting robot 8 to lower its height.
