Described pedal switch is micro-switch.
In order to realize the goal of the invention identical with technique scheme, the utility model also provides the method for operation of above-described construction machinery and equipment brake pedal, and its technical scheme is:
When stepping on stretcher, at first the push down on the pedal switch is controlled the electromagnetic valve on the power system oil circuit, and the oil circuit of power system is cut off, and power system stops power output, to guarantee the reliable and safety performance of braking; Continue to step on again stretcher downwards, promote dwang and drive the rotation of rotor plate assembly, drive the link gear of controlling air brake valve work, control air brake valve work, realize braking;
When unclamping stretcher, under the effect of stretcher torsion spring, stretcher starts to reset; Until after resetting fully, the power system oil circuit is connected, power system is recovered normal operation.
The utility model adopts technique scheme, before braking procedure, increased power cut, by cutting off oil circuit, reduce the energy supply to driving engine, thereby reduced the tractive force of car load, and then brake by air brake valve, thereby make air brake valve hang down loaded work piece, improved reliability and the safety of braking.
The accompanying drawing explanation
This specification sheets comprises the following drawings:
Fig. 1 is structural representation of the present utility model;
1, plug-in unit, 2, stretcher, 3, bracket assembly, 4, dwang, 5, pedal switch, 6, side plate is installed, 7, rotor plate.
The specific embodiment
Below contrast accompanying drawing, by the description to embodiment, the specific embodiment of the present utility model is described in further detail, to help those skilled in the art, inventive concept of the present utility model, technical scheme are had to more complete, accurate and deep understanding.
Structure of the present utility model as shown in Figure 1, for a kind of construction machinery and equipment brake pedal, comprise stretcher 2, and described stretcher 2 is articulated and connected with dwang 4, and described dwang 4 is articulated and connected with rotor plate 7.Described stretcher 2, by with bracket assembly 3, being articulated and connected, is realized rotating.
In order to solve the problem that prior art exists and to overcome its defect, realize improving car load deceleration and stopping performance, increase the goal of the invention of the safety and reliability of braking, the technical scheme that the utility model is taked is:
As shown in Figure 1, stretcher 2 of the present utility model is provided with pedal switch 5, and described pedal switch 5 is connected with the electromagnetic valve on the power system oil circuit by circuit.
The utility model improves prior art, design a kind of pedal assembly of belt switch, adopt the automatically controlled method combined with gas control, increased new brake control method, as existing braking system of engineering machinery, supplement, improve the deceleration and stopping performance of car load, increased the safety and reliability of braking.
Concrete structure is:
Described circuit is connected with the electromagnetic valve on described power system oil circuit by the plug-in unit 1 on circuit.
Pedal switch 5 is connected with stretcher 2, and stretcher 2 is connected with dwang 4, and dwang 4 is connected with rotor plate 7; One end of plug-in unit 1 is connected with pedal switch 5, and the other end is connected to form path by the electromagnetic valve on terminal and oil circuit; Pedal switch 5 is connected with stretcher 2 by the 4-M4 cross-recessed screw; Rotor plate 7 is connected with stretcher 2 by dwang 4;
