Fixing device of tyre valve of large-scale mining dumper

Abstract

The invention discloses a fixing device of a tyre valve of a large-scale mining dumper, belonging to the technical field of design application of tyre valve accessories of large-scale mining dumpers. The fixing device comprises a tyre valve (1), a hub (6), a splint (2), a fixed plate (7) and a hub gap key (5), wherein the fixed plate is fixedly arranged on the hub through a bolt, and the hub gap key is arranged in ahub gap; the tyre valve is embedded in the hub gap key and clamped by a circular arc surface of the splint; the splint and the fixed plate are fixedly connected through a first bolt (31) and a nut (4), and the fixed plate is also fixed and mounted on the hub through a second bolt (32). The fixing device disclosed by the invention has the beneficial effects of simple structure, convenience for operation, safety and reliability and capabilities of ensuring that the tyre valve cannot move and shift, effectively preventing tyre burst problem from appearing and prolonging the service lives of tyres and vehicles.

Description

technical field [0001] The invention relates to a fixing device for a tire valve, in particular to a fixing device for a tire valve of a large mining dump truck, and belongs to the technical field of design and application of tire valve accessories for a large mining dump truck. Background technique [0002] At present, construction machinery is developing towards large-scale, and mining dump trucks are also developing towards large-scale, so there are new and stricter requirements for the supporting components of large mining dump truck tires. [0003] There is a valve on the tire of the mining dump truck, which is used to inflate the car tire. The valve directly passes through the hole on the side wall of the wheel hub and tilts outward. As we all know, the road surface of large mining farms is rough, and the vehicle vibrates greatly when it is running. , The valve will shake, loosen and deflect, which will easily cause the sudden run-off and air leakage of the car tires, ...

Problems solved by technology

[0003] There is a valve on the tire of the mining dump truck, which is used to inflate the car tire. The valve directly passes through the hole on the side wall of the wheel hub and tilts outward. As we all know, the road surface of large mining farms is rough, and the vehicle vibrates greatly when it is running. , the valve will shake, loosen and deflect, which will easily cause the sudden run-off and air leakage of the car tires, and even lead to the danger of the vehicle running off suddenly, which will seriously endanger the safe driving of the vehicle and the personal safety of the staff.
