Abstract
The utility model particularly relates to a micro-motion operation device in a brake system of a heavy loaded 12-ton forklift, which comprises a micro-motion pedal 1, a pedal switch 2 and an air brake valve 6 and has the improvement by also comprising a motive power cutting-off electromagnetic valve 7, wherein the pedal switch 2 is arranged in a groove of the micro-motion pedal 1, the output end of the pedal switch 2 is connected with the motive power cutting-off electromagnetic valve 7 arranged on a gearbox through wire harnesses, one end of a micro-motion brake linkage mechanism 5 is connected with the micro-motion pedal 1, and the other end of the micro-motion brake linkage mechanism 5 is connected with the air brake valve 6. The micro-motion operation device has the advantages that the structure is simple, good motive power cutting-off performance is realized, the micro-motion brake action is accurate, and the operation and control performance of a whole vehicle is improved.
Description
Technical field
The utility model belongs to refitting fork truck technical field, is specifically related to fine motion operating control in the 12 ton forklift brake system.
Background technology
At present, the 12 ton forklift brake system of resetting have two kinds of functions, a kind of is that directly braking is stopped car load, another kind is to have fork truck fine motion function, it is that pallet fork fork truck near goods the time slowly moves that this kind function mainly acts on, to guarantee accurately to get goods near goods and fork, being unlikely to bump to goods. the fine motion function of existing 12 ton forklifts is to trample the fine motion pedal by left foot, drive the flexible axle drag-line under the pedal, the flexible axle drag-line applies tension and moves at change speed gear box boxed rod mechanism urges inching valve spool, with the pressure of power-transfer clutch in the change change speed gear box, thus the outputting power of cut-out change speed gear box.This kind maneuverability pattern has following shortcoming: 1, the flexible axle drag-line uses inside to draw core and outer protection cover clamping stagnation resistance to increase for a long time, makes fine motion bar linkage structure return inaccurate; 2, control clutch pressure effect is bad, and the change speed gear box clutch-lining often burns out.
The utility model content
In order to solve the deficiency more than the fine motion operating control in the existing refitting 12 ton forklift brake system, again improve design fine motion controlled pedal, on change speed gear box, increase the power cut electromagnetic valve, control the power cut electromagnetic valve in real time by the stretcher switch on the fine motion pedal, and by implementing the failure-free braking with the link gear of braking.The utility model provides fine motion operating control in a kind of refitting 12 ton forklift brake system.
Concrete technical solution is as follows:
Fine motion operating control in the 12 ton forklift brake system of resetting comprises fine motion pedal 1, pedal switch 2, air brake valve 6; Pedal switch 2 is installed in the groove of fine motion pedal 1, also comprises power cut electromagnetic valve 7 and fine motion braking link gear 5; The mouth of described pedal switch 2 is connecting power cut electromagnetic valve 7 on the change speed gear box by wire harness, and described fine motion braking link gear 5 one ends are connecting fine motion pedal 1, and the other end is connecting air brake valve 6.
Useful technique effect of the present utility model is:
1, simple in structure, easy for installation, maintainability is good, meets the requirement of ergonomics;
2, power cut is reliable, well protects the friction lining in the change speed gear box power-transfer clutch;
3, fine motion braking maneuver is accurate, has improved the car load handling.
Description of drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2, fine motion operating control in the 12 ton forklift brake system of resetting, mainly by comprising that band installs the fine motion pedal 1 of groove, pedal switch 2, wire harness 3, fine motion braking link gear 5, air brake valve 6, power cut electromagnetic valve 7. these steering units can be realized the linkage work of fine motion and braking under the change speed gear box power cut situation.
Its working process is as follows:
When car load needs micromotion, navigating mate is stepped on fine motion pedal 1, promptly the mouth of push down on the pedal switch 2, pedal switch 2 gives 7 one electric signal of power cut electromagnetic valve to cut off the takeoff output of change speed gear box through wire harness 3 simultaneously, work fine motion braking link gear 5 by connecting rod mechanism this moment, drive air brake valve 6 work, just can make the car load braking during air brake valve 6 work; Thereby just can control the car load micromotion as the slow control fine motion pedal 1 that only needs when mobile slowly of need.
Claims (1)
