Brake pedal of construction machinery for preventing slip by blowing with air bag

Abstract

The invention discloses a brake pedal of construction machinery for preventing slip by blowing with an air bag. The brake pedal comprises a fixed base, a blowing brake mechanism, a pedal anti-slip device and a support back cover. The blowing mechanism is used for blowing off dust on the shoe soles of a driver and dust falling on an anti-slip bar, and a main air bag cooperates with an air injectionmechanism to spray air to realize blow cleaning of the dust on the shoe soles and the anti-slip bar, so that the dust is prevented from being attached to the shoe soles to cause reduction of frictionforce with a pedal, a contact surface is protected from being worn to lose the anti-slip effect, the phenomenon of slippage in treading is effectively avoided, and the problem of potential safety hazard is solved. The air bag swells instantly through the air-injection device, in order that the outer surface is in contact with the anti-slip bar to generate slight vibration; the sand is prevented from falling into a sand guiding slot under the vibration action and is blown out from an outlet with a lateral air bag; the sand is cleaned effectively, and is prevented from being piled on the pedalto cause pedal wearing and influence on the braking effect; and the driving accident possibility is lowered.

Description

technical field [0001] The invention relates to the field, in particular to a brake pedal for a construction machine that utilizes an airbag to blow air to prevent slippage. Background technique [0002] As the name suggests, the brake pedal is a pedal that limits the power, that is, the pedal of the foot brake. The brake pedal is used to slow down and stop. The frequency of use is very high and directly affects driving safety. The brake pedal in the construction machinery, because there is a lot of sand and dust on the ground of the construction site, the soles of the driver's shoes are easy to carry sand and dust, which will cause slippage when stepping on the pedal. [0003] At present, the existing brake pedals for construction machinery have the following disadvantages: [0004] When the driver is walking on the construction site, the soles of the feet are easy to carry part of the sand and dust on the pedals, and the sand and dust will easily reduce the friction betwe...
