Portable manual rapid disassembly and assembly tool for snap-on run-flat tires

Abstract

The invention provides a portable type manual rapid dismounting and assembling tool for a card lock type anti-explosion tyre. The portable type manual rapid dismounting and assembling tool comprises a push-pull disc with a disc face located on the horizontal direction, wherein a central hole is formed in the center of the push-pull disc along the vertical direction; 3-16 strip-shaped through grooves are symmetrically formed in the disc face of the push-pull disc along the radial direction of the central hole; a bearing disc is arranged below the push-pull disc; rotary pin shafts are arranged at the edge of the bearing disc along the vertical direction; the quantity of the rotary pin shafts is the same as that of the through holes; each rotary shaft is correspondingly located below the inner side of the inner end of each through groove; each rotary shaft is connected with the inner end of a transverse beam in a mounting manner; a strip-shaped mounting groove is formed in each transverse beam along the axis direction. The invention aims to provide the portable type manual rapid dismounting and assembling tool for the card lock type anti-explosion tyre for the transportation safety of crawler-type vehicles; the portable type manual rapid dismounting and assembling tool is small in volume, is convenient to manually detach and assemble and is convenient to use and carry; the tyre can be detached conveniently, rapidly and safely and the labor is saved; tyre parts are not damaged and the working efficiency is high.

Description

Technical field [0001] The invention relates to a portable manual quick disassembly and assembly tool for a latching type explosion-proof tire. Background technique [0002] Heavy-duty wheeled vehicles have a wide range of uses in troops and places. In the army, wheeled armored vehicles are an important vehicle and weapon system for rapid mobility and combat of the army under the conditions of a modern road network. They have played an important role in all international wars in recent years. Due to the demand for local warfare under high-tech conditions and the need to quickly deal with emergencies in my country, the demand for wheeled armored vehicles and the amount of power are also increasing; in places, heavy wheeled vehicles are widely used in large equipment In occasions such as transportation of raw materials, mining, etc., it has a large quantity and is frequently used. For this reason, the market has a very urgent demand for maintenance tools for heavy-wheeled vehicles...

AI Technical Summary

Problems solved by technology

For this reason, the market demand for heavy-duty wheeled vehicle repair and maintenance tools is also very urgent, and the snap-lock type run-flat tire is a component that consumes quickly and is easily damaged during the use of heavy-duty wheeled vehicles. The user unit often faces the need to replace and repair tires In some cases, especially in long-distance transportation and field conditions, tire failure means that the vehicle cannot continue to be used. Safe and fast tire replacement and repair is a major issue that is highly valued by the user.

In order to ensure that the lock-type explosion-proof tires of heavy-duty wheeled vehicles can withstand greater pressure and withstand the needs of complex and harsh service conditions, solid tires, high-strength rubber and wire mesh materials, snap rings, pressure rings, wheel hubs, etc. are often used The parts are assembled together in the way of locking. Due to the complex structure of this tire group and the large pressure required for assembly and disassembly, it can only be disassembled and assembled in professional repair places by relying on large hydraulic special tools. It is very difficult for maintenance personnel to disassemble and assemble this type of snap-lock type run-flat tire by themselves. Even if 3 to 5 people use conventional tools to cooperate and reluctantly disassemble and assemble, it is very easy to cause damage to the snap ring and pressure ring due to violent disassembly and assembly, making related Parts are completely scrapped
