Method for maintaining normal unloading of mining dump truck in winter and exhaust and heating system

Abstract

The invention provides an exhaust and heating system for a bottom plate of a mining dump truck, which aims to improve the dump performance of a vehicle in winter. In a method, the bottom plate is heated by utilizing the heat of an exhaust gas emitted by an engine to prevent goods on the bottom plate from being frozen at edges and corners of a wagon body. In the exhaust and heating system for the bottom plate of the mining dump truck, an exhaust butterfly valve is connected to the gas outlet end of an exhaust pipe, and is connected to an underframe assembly of the wagon body of the vehicle through a pipeline; joints of transverse beams and longitudinal beams in the underframe assembly are all communicated to form a continuous closed gas circuit; and two exhaust ports are reserved on rear beams of the underframe assembly. In the system, the exhaust gas emitted by the engine is reutilized, and the bottom plate is heated by the heat of a tail gas to eliminate the freezing phenomenon and realize the normal unloading of the goods. A muffler is removed, and the system functions in muffling at the same time of heating the bottom plate so as to reduce the cost and make waste profitable.

Description

Technical field [0001] The invention belongs to the technical field of transportation vehicle manufacturing, especially the field of mining dump trucks. Background technique [0002] For mining dump trucks operating in high-cold areas, the cargoes such as sand, gravel and soil will freeze at the edges and corners of the car body under low temperature conditions. When the dump truck lifts beyond the angle of rest of the cargo, some cargo cannot be unloaded. As a result, the overall utilization rate of the cabinet is low, and it is difficult to manually clean it later. Summary of the invention [0003] The purpose of the present invention is to provide an exhaust and heating system for the floor of a mining dump truck to improve the dump performance of the truck in winter. [0004] Specifically, to maintain the normal unloading method of mining dump trucks in winter is to use the heat of the exhaust gas discharged from the engine to heat the bottom plate to prevent the cargo on the b...

Problems solved by technology

[0002] Mining dump trucks operating in alpine regions, the sand, soil and other goods loaded by them will freeze at the corners and corners of the car body under low temperature conditions. When the dump truck is lifted beyond the angle of repose of the goods, some goods cannot be unloaded. As a result, the overall utilization rate of the cabinet is low, and it is difficult to manually clean it later
