Abstract
The invention discloses a foot pedal operating mechanism which comprises the components of a foot pedal, a mounting board, a pin, a supporting seat and a pull rod. Positioning connection between the foot pedal and the supporting seat is realized through the pin. The pull rod is connected with the foot pedal through a bolt. The mounting board is fixed on the floor of a driver cab. The mounting board is provided with a rabbet. The length of the rabbet is larger than the working stroke of the foot pedal. The foot pedal has a panel which is made of a bent board. A rubber protective sleeve is mounted outside the foot pedal, so that the foot pedal is more suitable for force application by a human foot. Furthermore, multiple connecting holes between the foot pedal and the pull rod are arranged. The magnitude of a control force is changed through mounting in different holes, thereby satisfying the requirements of different operators. Integral milling is applied on the supporting seat, thereby effectively settling a transverse idle stroke of the foot pedal. A ball joint rod ends bearing is adopted at the connection portion between the pull rod and the foot pedal. The position relationship between the pull rod and a valve core is better adjusted. The foot pedal operating mechanism has advantages of simple structure, high reliability, attractive appearance, etc. Furthermore the operability of the foot pedal operating mechanism is greatly improved.
Description
Technical field
The present invention relates to a kind of catanator of engineering machinery, particularly control the pedal control mechanism of main control core valve open and close, belong to technical field of engineering machinery.
Background technology
Main control valve is the major control element of engineering machinery, and the quality of its performance directly affects the performance of engineering machinery, particularly its control gear.Existing main control valve control gear mainly contains pilot control mechanism and mechanical control mechanism two kinds.Because the structure of mechanical control mechanism is simple, easily manufactured and reliability is high, it is widely used in the control field of engineering machinery.Pedal control mechanism is a kind of form of main control valve control gear, but existing pedal control mechanism also exists complex structure, and understeer is lived, and steering force is large, has the problems such as idle motion in motion process.The existence of problems, has a strong impact on operating performance and the pedal control mechanism popularization of applying in engineering machinery of machinery.
Summary of the invention
The present invention proposes in order to the shortcoming overcoming above-mentioned prior art and exist, and its technical matters solved is to provide that a kind of structure is simple, easy for installation, idle motion is few, can be applicable to the pedal control mechanism of different crowd.
A kind of pedal control mechanism, comprise foot-operated, installing plate, bearing pin, bearing, pull bar, foot-operated with adopt bearing pin to position between bearing to be connected, pull bar and foot-operated between with bolts, installing plate is fixed on the floor of pilothouse, installing plate has notch, and the length of notch is greater than foot-operated impulse stroke, and described riding comprises slipmat, foot-operated face and foot-operated body; Described slipmat is fixed on foot-operated face; Described foot-operated body is welded in bottom foot-operated face, and it is connected with pull bar with bearing.
Preference, in order to the demand of the person that meets different operating, the quantity of described foot-operated body and bearing connecting hole is more than or equal to two; The quantity of described foot-operated body and pull bar connecting hole is more than or equal to two.
Preference, conveniently manufactures, and meets Human Engineering Principle, and described foot-operated face is bending part, and its bending angle is 135 ° ~ 150 °.
Preference, in order to the replaceability of operator's comfortableness and consumable accessory, described slipmat is rubber sheath, and the fixed form in itself and foot-operated face is assembled.
Preference, in order to solve foot-operated idle motion problem, described bearing is monoblock type, and itself and foot-operated contact level are milling face.
Preference, in order to pull bar adjustable length is easy for installation, described pull bar and foot-operated body junction adopt bulb spherical plain bearing rod end.
The present invention is relative to prior art, and have structure simple, the features such as reliability is high, fashionable appearance, improve maneuverability greatly, is applicable to various working and crowd.
Accompanying drawing explanation

Fig. 2 is structural representation left view of the present invention;
Fig. 3 is the embodiment structural representation of bearing;
Fig. 4 is foot-operated embodiment structural representation.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, a kind of pedal control mechanism, comprise foot-operated 1, installing plate 2, bearing pin 3, bearing 4, pull bar 5, foot-operated adopt bearing pin 3 to position between 1 with bearing 4 to be connected, with bolts between pull bar 5 and foot-operated 1, installing plate 2 is fixed on the floor of pilothouse, and installing plate 2 has notch, the impulse stroke that the length of notch is greater than foot-operated 1, described foot-operated 1 comprises slipmat 11, foot-operated face 12 and foot-operated body 13; Described slipmat 11 is fixed on foot-operated face 12; Described foot-operated body 13 is welded in bottom foot-operated face 12, and it is connected with pull bar 5 with bearing 4.
As shown in Figure 4, its steering force be applicable to of different operators is different, because described foot-operated body 13 is more than or equal to two with the quantity of bearing 4 connecting hole; Described foot-operated body 13 is more than or equal to two with the quantity of pull bar 5 connecting hole, and when different operating person operates, it can regulate according to the demand of oneself steering force be applicable to.
Present engineering machinery more and more focuses on the comfortableness of operator, and Human Engineering Principle obtains broad development in engineering machinery.Foot-operated face 12 is made into bending part, while being convenient to processing, improves its rigidity.Foot-operated face 12 is converted into 135 ° ~ 150 °, and rubber sheath slipmat 11 is assembled in foot-operated face 12, improves operation comfort, is convenient to the replacing of later stage consumable accessory.
As shown in Figure 3, idle motion has a strong impact on real-time and the fine motion of control gear, and described bearing 4 is made into monoblock type, and itself and foot-operated body 13 surface of contact are milling face, effectively avoid foot-operated 1 to rock, and reduces idle motion.
Pull bar 5 and foot-operated body 13 junction adopt bulb spherical plain bearing rod end, can the position relationship of better adjusting yoke 5 and main control valve spool, remove the stress in all the other directions.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of application claims.
