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
The invention belongs to transport vehicle manufacturing technology field, particularly quarry tipper field.
Background technology
At the quarry tipper of extremely frigid zones operation, its cargo-carring sandstone, earth and other items can freeze at envelope corner angle and edge under cryogenic conditions, when the dumping car lifting surpasses the goods angle of repose, part cargo can't unload, and causes the casing overall utilization rate low, and the later stage is difficult to the labor cleaning.
Summary of the invention
The object of the invention provides exhaust of a kind of quarry tipper base plate and heating system, to improve vehicle self-unloading in winter performance.
Specifically, keep quarry tipper normal discharging method in winter, it is to utilize the heat of the waste gas of driving engine discharge to heat to base plate, prevents that goods freezes at envelope corner angle and edge on the base plate.
Exhaust of quarry tipper base plate and heating system, it is to be connected with the exhaust butterfly valve in the freeing pipe outlet side, the exhaust butterfly valve inserts in the chassis assembly of the big railway carriage or compartment of vehicle by pipeline, and chassis assembly. center member, longeron junction all connect and constitute continuous osed top gas circuit, open two exhausr ports on the crossbeam of chassis assembly back.
The waste gas that the present invention discharges by driving engine utilizes again, heats to base plate with the heat of tail gas, removes and freezes phenomenon, and the realization goods normally unloads.The present invention removes silencer, takes into account the function of noise reduction in the base plate heating, is that cost-cutting is turned waste into wealth again like this.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is Fig. 1 birds-eye view.
Fig. 3 moves towards scheme drawing for gas circuit in the chassis assembly of the present invention.
The specific embodiment
Provided the specific embodiment of the invention as Fig. 1,2,3.
Keep quarry tipper normal discharging method in winter, it is to utilize the heat of the waste gas of driving engine discharge to heat to base plate, prevents that goods freezes at envelope corner angle and edge on the base plate.Remove silencer on the engines tail tracheae, the freeing pipe outlet side connects into and gives the base plate heat supply in the chassis assembly of the big railway carriage or compartment of vehicle.
Exhaust of quarry tipper base plate and heating system, it is connected with exhaust butterfly valve 2 in freeing pipe 1 outlet side, exhaust butterfly valve 2 inserts in the chassis assembly of the big railway carriage or compartment of vehicle by pipeline, and chassis assembly center member, longeron junction all connect and constitute continuous osed top gas circuit, open two exhausr ports on the crossbeam of chassis assembly back.Being connected with flexible soft pipe 3 on the exhaust butterfly valve 2 also is communicated with exhaust expansion bellows 6 by 5 commutations of exhaust square box joint, exhaust expansion bellows 6 inserts in the chassis assembly of big railway carriage or compartment, and the base plate joint 4 that is used to regulate exhaust system and big locus, railway carriage or compartment and sealing function is housed between exhaust expansion bellows 6 and big railway carriage or compartment chassis assembly.
In the chassis assembly, crossbeam, longeron junction are connected.In different places dividing plate is set, stops that gas circuit walks along straight line, evenly heatable soleplate and exhaust noise silencing effect.Local all full welds that all gas circuits are passed by.Open two exhausr ports on the crossbeam of chassis assembly back, it is smooth and easy to be convenient to exhaust, prevents that one the tunnel blocks, and suppresses dead driving engine.
Principle of work: from the waste gas that freeing pipe comes out, through the exhaust butterfly valve, to flexible soft pipe, by the commutation of exhaust square box joint, waste gas enters in the chassis assembly of big railway carriage or compartment by bellows.Wherein the base plate joint action is to regulate exhaust system and big locus, railway carriage or compartment and sealing function (attention be not influence the energy brake normal operation).
