Embodiment Construction

[0008] Referring to attached drawing 1, the power take-off switch a is actually a two-position three-way valve, which is normally closed when driving, that is, port 1 and port 2 of the three-way valve are disconnected. At this time, the power take-off cylinder d has no input Gas, does not work, that is, the lifting system of the dump truck does not work; when parking for lifting operations, the power take-off switch is connected, that is, port 1 and port 2 are connected, the power take-off is connected to the pump, and the lifting system works .

[0009] It can be seen from Figure 1 that the butterfly valve c on the exhaust pipe and the butterfly valve b on the branch of the exhaust pipe share an air port 2 with the power take-off. When driving, port 2 and port 3 (exhaust port of the power take-off) are connected, there is no air pressure in the air circuit, the power take-off and the pump are not connected, the lifting system is not working, and the butterfly valve c on the e...

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: [0001] The invention relates to an air-controlled heating method for a bottom plate of a dump truck. Background technique: [0002] At present, the bottom plate heating of domestic dump trucks is mechanically controlled. Due to the error in the manufacturing process, the mechanical control mechanism often causes air leakage, which leads to poor control reliability of the control mechanism and affects the effect of the bottom plate heating. Invention content: [0003] The purpose of the present invention is to improve the convenience and reliability of the control, completely eliminate the air leakage phenomenon caused by the error of the mechanical structure in the manufacture, improve the effect of the bottom plate heating, and provide an air-controlled heating method for the bottom plate of the dump truck, which is used for Replace the original mechanical mechanism. [0004] The purpose of the present invention is achieved in the following ways: [000...
