Fixing device for tire burst prevention system of dangerous goods heavy truck

Abstract

The invention provides a fixing device for a tire burst prevention system of a dangerous goods heavy truck. The device comprises transverse connecting rods, longitudinal connecting rods, vertical rods, a short rod, a reinforced vertical rod, a reinforcing cross bar, a reinforced inclined strut, a mounting plate, a cylinder, a circular plate, a circular limiting ring, a long rod, and mandrils. Withthe cylinder, after the cylinder acts, the push rod pushes the axis of a rim through the circular plate, the telescopic path of the push rod penetrates the circle center of the circular limiting ring, so that the tire and the rim are accurately pushed out, the circumference of the tire is evenly stressed, and thus the situation that the tire is damaged due to uneven stress is prevented; due to the arrangement of the circular limiting ring, the inner diameter of the circular limiting ring is larger than the diameter of the truck rim, so that the rim can be separated from the circular limitingring and an explosion-proof system is convenient to install; because of the circular limiting ring and the circular plate, the cylinder acts a pushing force on the circular plate and the circular plate makes direct contact with the rim, and no external force makes contact with the tire, so that separation of the tire and the rim is guaranteed, and the tire and the rim can be prevented from being scratched.

Description

technical field [0001] The invention belongs to the technical field of tire assembly, and in particular relates to a fixing device for a run-flat-proof tire system of a dangerous goods heavy truck. Background technique [0002] The tires of heavy-duty trucks with dangerous goods have been running under high load for a long time, and even the tires are prone to blowout after long-term operation. According to national regulations, tires of heavy-duty trucks with dangerous goods must have a flat-proof tire system. [0003] When the wheel is equipped with an explosion-proof system, the tire and the rim need to be separated. However, when the existing tire changer separates the tire from the rim, it is easy to cause damage to the rim and the tire, which reduces the service life of the tire and the rim, and disassembly is very difficult. trouble. [0004] Therefore, it is very necessary to invent a kind of dangerous goods heavy truck run-flat tire system fixing device. Contents...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a fixing device for the anti-run tire system of dangerous goods heavy trucks, so as to solve the problem that the tire and the rim need to be separated when the wheel is equipped with an explosion-proof system. When separating, it is easy to cause damage to the rim and tire, which reduces the service life of the tire and rim, and is very troublesome to disassemble.
