Description
Technical Field
The invention relates to a stone removing device for a mining dump truck, and belongs to the field of mining dump trucks.
Background
The mining dump truck is large-scale transportation equipment for mines, and the rear wheels of the mining dump truck are usually in a single-side double-tire structure due to the limitation of the bearing capacity of tires. A gap is reserved between the double tires to ensure the normal work of the tires in the running process of the vehicle. The gap can cause the vehicle to block foreign matters such as stones during running, and cause abnormal wear and even tire burst of the tire. Therefore, a calculus removing device with excellent and safe performance is urgently needed, and the safe operation of equipment is ensured. At present, the stone removing device used on the mining dump truck has two types, namely a stone removing rod type and a single stone removing chain type. If the stone is clamped too tightly, the stone discharging rod can be bent and deformed, and the deformed stone discharging rod causes secondary damage to tires. If the tire is not found in time, the early abnormal abrasion of the tire can be caused, and the service life of the tire is shortened. The mining dump truck tire is expensive, and the service cost of a user can be greatly improved by shortening the service life of the tire. The single stone removing chain is easy to be rolled into the rim space ring due to overlong length, and the stone removing function is lost. There is an urgent need for a safe and reliable calculus removing device.
