The invention discloses an accelerator control device of an underground internal combustion scraper, and relates to the technical field of accelerator control devices. The accelerator control device comprises a bottom plate and a support, wherein the support is fixedly connected to the upper surface of the bottom plate. According to the accelerator control device, by the adoption of a stop block,a first spring, a second spring, a third spring, a pressing block, a movable frame, a movable plate and the like. The situation that when people use an accelerator, the accelerator is too large due tooverexertion can be prevented by the structure, obvious staged pressure changes exist in the use process, stress feedback is good, the safety coefficient is high, according to the accelerator controldevice, by means of a metal pipe, an air bag and a box body, when a cylinder body swings, the metal pipe moves along with the cylinder body, then the bottom of the metal pipe drives the air bag to extrude the box body, the air bag can conduct air exchange, air exchange is conducted between the cylinder body and the outside, heat dissipation of the first spring in the cylinder body is facilitated,and metal fatigue is avoided.
Description
technical field [0001] The invention belongs to the technical field of accelerator control devices, in particular to an accelerator control device for an underground internal combustion scraper. Background technique [0002] The scraper is a kind of shovel transport machine that uses a bucket to shovel the soil and put the crushed soil into the bucket for transportation. Real comprehensive work. It is suitable for the leveling work of road, water conservancy, electric power and mining and other projects. The scraper has the advantages of simple operation, no terrain restriction, independent work, fast driving speed and high production efficiency. [0003] However, if the throttle of the scraper is stepped on too hard, the engine speed will rise rapidly. Improper operation is dangerous and lacks a force feedback structure. The present invention proposes an underground internal combustion scraper throttle control device for the above problems. Contents of the invention ...
