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, ...

Examples

Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing.

[0011] Such as figure 1 As shown, a large mining dump truck tire valve fixing device includes a tire valve 1 and a wheel hub 6, and also includes a splint 2 and a fixing plate 7 fixedly installed on the wheel hub 6 by bolts 3, and is set in the gap of the wheel hub 6 The hub notch key 5; the tire valve 1 is nested in the hub notch key 5, and is clamped by the circular arc surface of the splint 2, the splint 2 and the fixed plate 7 are fixedly connected by the bolt 3 and the nut 4, and the fixed plate 7 passes through The bolt 3 is fixedly mounted on the hub 6 .

[0012] The fixing plate 7 is L-shaped, and can be finely adjusted according to the actual needs of the valve 1 installation. If the valve is installed not parallel to the notch key 5 of the hub, but slightly off-angle with the notch key 5 of the hub, the bolt can be loosened 3. Adjust the angle between the splint...
