Description
Technical field
Bottom plate of dump truck utilizes tail gas heating structure, relates to a kind of heating device technology area of dumping car.
Background technology
When dumping car carries out goods transport in north cold area winter, if when goods is wet soil side or wet coal and other items, because existing body of tipper carriage does not have special preheating device, exhaust emissions as shown in Figure 1, tail gas is by directly entering atmosphere after freeing pipe and noise silencer, not only cannot utilize tail gas heat quantity but also foul air.Like this in the time that temperature is too low, wet cargo will with cabin floor panel freeze clean together with, cause thoroughly self-unloading of goods, also need the removing of manually unloading, hand labor intensity is too large like this, work efficiency is too low.Also there is minority dumping car to carry out waste gas utilization, but UNICOM's structural arrangement of floor beam and longeron is unreasonable, affected the structural strength in compartment, and the design of admission port device is also reasonable not when waste gas utilization, due to body of tipper carriage for a long time frequently lifting to press down gas leak phenomenon more serious.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of rationally distributed heating arrangement that utilizes the tail gas of dumping car self to carry out vehicle cabin floor board.
For solving the problems of the technologies described above, the technical solution adopted in the present invention: bottom plate of dump truck utilizes tail gas heating structure, comprise cabin floor panel, four longerons, some crossbeams and exhaust emissions admission port device, described four longerons and some crossbeams are hollow structure, four longerons and some crossbeams are that crisscross formula is arranged at described cabin floor panel, and four longerons are all connected with the base seal of cabin floor panel with some crossbeams, have the air extractor vent of connecting longitudinal and cross beam at the cross-point interval of four longerons and some crossbeams, all have the base plate air extractor vent communicating with some crossbeams in the both sides of cabin floor panel, be provided with stock guide at cabin floor panel top and side carriage plate junction, the air-flow of described base plate air extractor vent can communicate with stock guide, have an induction opening communicating with exhaust emissions admission port device at cabin floor panel near one end of headstock, all have and the deflation hole that heats exhaust pipe and communicate near the both sides, one end of the tailstock at cabin floor panel,
The base plate air extractor vent position of described cabin floor panel both sides and the air extractor vent position of four longerons and some crossbeam cross-points are along the crossbeam horizontal alignment at air extractor vent place;
