The device is provided with a draw rod, one end of the draw rod is connected with a hydraulic valve controller, and a left controlling rod of the hydraulic valve controller flatly passes through a shifting fork to be connected with a travel switch. A connecting fork of an accelerograph controlling mechanism passes through one side of a pin shaft to be connected with a right controlling rod. A cam is connected with an accelerograph by a spring, a connecting supporting seat and a connecting draw wire. The utility model has the advantages of reasonable structure design, artful concept, compact structure and convenient operation. The labor intensity of operators is reduced, the coordination working of an engine and a hydraulic multiple-way valve is ensured, the power of the engine is efficiently used, energy is saved, and the service life of hydraulic elements is lengthened.
Description
The utility model relates to a kind of hoist hydraulic valve operating accelerator linking device.
At present, the hydraulic multichannel combination brake switch and proporting control of being adopted in the industry of truck crane is regulated with engine throttle and is respectively independent manipulation, wherein, the hydraulic multichannel combination brake switch and proporting has a combination brake switch and proporting, one end of combination brake switch and proporting connects right operating handle by pull bar, shift fork, the other end connects shift fork, and shift fork connects left operating handle.Another independent manipulation partly is an engine throttle, and engine throttle has a pull bar, and an end of pull bar connects clevis by bearing pin, clevis connects left operating handle, middle upper part connects the pinnacle pin, and the pinnacle pin connects support by spring, and the support bottom has the backguy level to pass, backguy connects connecting plate on one side, the connecting plate cylinder lever connecting rod, another side connects throttle, and the other end connects clevis by bearing pin, clevis connects right operating handle, and the bottom connects bearing by coupling shaft.This structure is when operating hydraulically operated multi-way valve and engine throttle, Joystick on the necessary operating hydraulically operated multi-way valve earlier of operator, under the situation that spool moves into place, the Joystick of while on the maneuvering engine throttle, because the two actuating element is respectively two independent agencies, and is not only comparatively loaded down with trivial details on the layout of complete machine, and the operator to operate two handle labor intensity simultaneously big, throttle does not have auto-lock function, and the rate conversion of motor is not steady.
The purpose of this utility model provides a kind of integrated control, and the self-marketing function is arranged, and labor intensity is little, and speed change is hoist hydraulic valve operating accelerator linking device stably.
The purpose of this utility model is achieved in that this device has a pull bar, and pull bar one end connects the controller of hydrovalve, and the other end connects manipulating mechanism of oil throttle.
Hydraulic valve controller has a left operating handle, and left operating handle level is passed shift fork and connected position limit switch, and position limit switch connects the shift fork bottom by bearing pin.
Left side operating handle has a connecting rod, and the connecting rod outer surface is with left axle sleeve, and an end is connected right axle sleeve by bolt with spacer, is connected with spring between left and right bushing and overcoat, and an end of overcoat connects connecting ring, and the other end connects connecting rod.
Manipulating mechanism of oil throttle has a clevis, clevis connects right operating handle on one side by bearing pin, another side connects cam, cam connects cylinder, cylinder connects regulator plate, and regulator plate one side connects positioning shaft, and opposite side connects bearing by spring, the spring below connects backguy, and the backguy level is passed bearing and connected throttle.
Cam is fan-shaped, and an end has a circular hole, and there is a curve bath centre, is connected with position limit pin in the groove, and the other end is a curved surface.
Owing to adopted such scheme, this device has a pull bar, pull bar one end connects the hydrovalve control section, the hydrovalve control section has a left operating handle, left side operating handle level is passed shift fork and is connected position limit switch, position limit switch connects the shift fork bottom by bearing pin, and the other end connects manipulating mechanism of oil throttle, and manipulating mechanism of oil throttle has a clevis, clevis connects right operating handle on one side by bearing pin, another side connects cam, and cam connects cylinder, and cylinder connects regulator plate, regulator plate one side connects positioning shaft, opposite side connects bearing by spring, and the spring below connects backguy, and the backguy level is passed bearing and connected throttle.When the operator rotates left operating handle or right operating handle, shift fork, left side operating handle is around the bearing pin turn, valve core of hydraulic reversing valve moves, realization is to the control of hydraulicdirectional control valve, continue left operating handle of rotation or right operating handle again, shift fork, it is the center rotation that left side operating handle continues with the bearing pin, the spring pressurized in the left operating handle, clevis simultaneously, it is the center rotation with the positioning shaft that cam drives regulator plate by cylinder, regulator plate pulling acceleration cable, regulate engine throttle, change in the past the sort of separately manipulation and be independent manipulation, form integrated control, simplify the structure, make things convenient for the layout of complete machine, reduced operator's labor intensity, because cam is fan-shaped, there is curve bath the centre, connect position limit pin in the groove, position limit pin mainly is the swing position of restriction cam, and the other end is a curved surface, so, the throttle braking of motor is by the contour surface self-locking on the cam, has guaranteed that the speed change of motor is steady, has realized the purpose of this utility model.This reasonable in design is skillfully constructed, compact structure, and easy-to-operat has reduced operator's labor intensity, has guaranteed the co-ordination of motor and hydraulic multitandem valve, effectively utilizes the power of motor, saves the energy, prolongs the working life of hydraulic element.
