Description

TECHNICAL FIELD

[0001] The utility model relates to a tire post-inflation device, in particular to a horizontal multi-station post-inflation device with multi-level adjustable width. BACKGROUND

[0002] After the vulcanization of large engineering tires, tire deformation during the cooling process is inevitable. The deformed tire brings great trouble during use and installation, and even safety accidents may occur. Therefore, post-inflation and setting cooling of the tire after vulcanization is a necessary process.

[0003] Traditional post-inflation equipment for large engineering tires generally adopts a single-station vertical structure, but this structure has the following disadvantages: 1. Only one tire can be inflated at a time, and the work efficiency is low; 2. The equipment occupies a large area, wasting factory resources; 3. The tires are placed horizontally during inflation, which makes loading, unloading, and handling difficult, and the work intensity is high; 4. The range of tire width suitable for inflation is small.

[0004] A horizontal multi-station post-inflation device is improved, as disclosed in the utility model patent CN210100767U. This scheme proposes a multi-station post-inflation device for engineering tires, which can inflate multiple tires at the same time, making the operation more convenient and the inflation efficiency higher. However, this structure still has some disadvantages: the device uses a locking rod structure, and since the length of the locking rod is fixed, it cannot adapt to a large range of tire width changes, and the range of tire specifications that can be adapted is limited. SUMMARY

[0005] To overcome the shortcomings of the prior art, the utility model provides a horizontal multi-station post-inflation device with multi-level adjustable width, which uses a multi-level adjustment method to inflate multiple tires at the same time and greatly increases the range of tire width suitable for inflation.

[0006] The utility model achieves the above-mentioned purposes through the following technical solutions:

[0007] A horizontal multi-station post-inflation device with multi-level adjustable width, comprising a rack, two upper and lower parallel guide rods installed in the rack, a clamping beam and a plurality of movable beams longitudinally sliding between the two guide rods, a stop cylinder fixed on the clamping beam, a left chuck connected to the piston rod of the stop cylinder, a left chuck and a right chuck respectively installed on the movable beam, a right chuck fixed on the right side of the rack, the left chuck and the right chuck coaxially arranged with the stop cylinder, a positioning cylinder installed on the left side of the rack, the piston rod of the positioning cylinder connected to the clamping beam, a plurality of clamping grooves opened on the guide rod, and the clamping beam limited by a pneumatic clamping device.

[0008] Further, the two ends of the clamping beam and the movable beam are connected to the guide rod through rolling linear shaft sleeves.

[0009] Compared with the prior art, the utility model has the advantages and effects that

[0010] 1. The traditional locking rod structure is abandoned, a double guide rod structure with a clamping groove is adopted, the movable beam slides on the guide rod through a rolling linear shaft sleeve, the movement resistance is small, the operator can easily move, and the double guide rod structure can better guarantee the coaxiality of the chuck and the tire quality.

[0011] 2. A multi-stage adjustment mode is adopted, that is, the total width of the pneumatic tire can be adjusted in the stroke range of the position adjusting oil cylinder and the retreat stopping oil cylinder, so that the device can adapt to the demand of large cumulative width change range of different width tires.
