Abstract
The invention relates to the self dismounted vehicle bottom plate pneumatic control heating method, features in the exhaust pipe branch whose opening targeting to the bottom plate of the case, a controllable butterfly valve in constant open state on the muffler and exhaust pipe, opening or close of the controllable butterfly valve being able to control the compression air to control the switch, the constant open controllable butterfly on the exhaust pipe branch closes when the force getting machine switch connects. It is completely opposite to the butterfly valve of the exhaust pipe connected to the muffler. It is convenient and reliable in control, completely getting rid of the air leakage in mechanical structure and manufacturing, improved in bottom plate heating effect.
Description
Technical field:
The present invention relates to a kind of dumping car bottom board gas control heating method.
Background technology:
At present, the base plate of domestic dumping truck is heated to be mechanical control, and this mechanical control mechanism is because error in the mill, and the gas leak phenomenon that often causes takes place, and causes the control reliability of control mechanism poor, has influenced the effect of base plate heating.
Summary of the invention:
The objective of the invention is in order to have improved the convenience and the reliability of control, thoroughly eliminate the gas leak phenomenon that physical construction error in the mill causes, improve the effect of base plate heating, a kind of dumping car bottom board gas control heating method is provided, be used for replacing original mechanical mechanism.
The objective of the invention is to realize by following mode:
The present invention is provided with a freeing pipe branch on the dumping car exhaust pipe of engine, the mouth of pipe of freeing pipe branch is facing to dumping car casing base plate, on freeing pipe, before the silencer He in the freeing pipe branch a controlled butterfly valve is installed respectively, the unlatching of controlled butterfly valve or close and handle pressurized air by power take-off valve in the operator's compartment and control, the controlled butterfly valve that is positioned in the freeing pipe branch is normal opening, closes when power take-off valve is connected; With silencer bonded assembly freeing pipe place butterfly valve be normal closed condition, when power take-off valve is connected, open.
Advantage of the present invention is: control is convenient reliable, has thoroughly eliminated the gas leak phenomenon that physical construction error in the mill causes, and has improved the effect of base plate heating.
Description of drawings:
Fig. 1 is a schematic diagram of gas circuit of the present invention.
The specific embodiment:
With reference to accompanying drawing 1, power take-off valve a is actual to be a two position three-way valve, is in closed condition when usually promptly driving a vehicle state, and promptly the mouth 1 of triple valve disconnects with mouth 2, and this moment, power takeoff cylinder d did not have air inlet, did not work, and just the dumping car hoisting system is not worked; When the lifting operation was carried out in parking, power take-off valve was connected, and promptly mouth 1 is connected with mouth 2, and power takeoff engages with pump, hoisting system work.
By accompanying drawing 1 as can be known, butterfly valve b and the shared gas port 2 of power takeoff in butterfly valve c and the freeing pipe branch on the freeing pipe.When driving, mouth 2 communicates with mouthful 3 (power takeoff exhausr ports), no air pressure in the gas circuit, power takeoff does not engage with pump, hoisting system is not worked, simultaneously butterfly valve c is in long closing on the freeing pipe, and butterfly valve b is in normally open in the freeing pipe branch, and the gas that driving engine is discharged can not communicate with silencer and butterfly valve b heatable soleplate in the freeing pipe branch.When the lifting operation is carried out in parking, power take-off valve a connects, be that two position three-way valve is in 2 on the left side, mouth 1 (source of the gas) communicates with mouth 2, and power takeoff engages with pump, and hoisting system is in running order, butterfly valve c is in 2 of connections on the freeing pipe at this moment, and butterfly valve b is in 2 of disconnections in the freeing pipe branch, the gas impassabitity butterfly valve b that driving engine is discharged, and discharge through butterfly valve c and by silencer.
Claims (1)
1, a kind of dumping car bottom board gas control heating method, it is characterized in that: a freeing pipe branch is set on the dumping car exhaust pipe of engine, the mouth of pipe of freeing pipe branch is facing to dumping car casing base plate, on freeing pipe, before the silencer He in the freeing pipe branch a controlled butterfly valve is installed respectively, the unlatching of controlled butterfly valve or close and handle pressurized air by power take-off valve in the operator's compartment and control, the controlled butterfly valve that is positioned in the freeing pipe branch is normal opening, closes when power take-off valve is connected; With silencer bonded assembly freeing pipe place butterfly valve be normal closed condition, when power take-off valve is connected, open.
