Description
Technical field the utility model relates to a kind of master controller
Background technology is present, and the kind of master controller is a lot, and wherein the structure of the master controller of Siemens production is comparatively advanced.This master controller mainly includes: the steering unit of being made up of frame, universal pivoted frame and locations, joystick, elastic covering and transmission gear, the cam activated switch mechanism that forms by camshaft, axle sleeve, cam bit, adapter plate, pillar, contact assembly, permanent seat, ratchet, lever, roller, spring, screw etc., and the automatic reset mechanism of forming by rotating shaft, axle sleeve, stop block, locations, spring leg.But also there is certain defective in this master controller:
1, cam is fixed on the camshaft, as it is very difficult to want to change deciliter program of itself and contact.
2, the grafting of contact assembly and permanent seat is an elasticity of utilizing the contact mounted panel, and this structure is unreliable, the plug easy fracture, and waste product was higher when particularly it was cold.
3, carrying the handle lower semisphere always during normal running, making joystick leave zero-bit, if work-hours is long slightly, it is very tired that the operator can feel.
4, contact assembly is enclosed in the opaque mounted panel, easy-to-search not when breaking down.
The summary of the invention the purpose of this utility model be to provide a kind of can conveniently change contact deciliter program, plug freely, the hoisting crane control desk master controller of rapid operation, fault easy-to-search.The utility model mainly is to have carried out some improvement at the deficiencies in the prior art.At first be the improvement to joystick: the connecting rod that the lower end links to each other with swivel mount is a pipe, and its upper end of passing the bent axle cylindrical void is threaded with center slotted eye in the handle episphere.It is the vertical cylindrical void of symmetry with the axis that the top of this connecting rod is provided with two, and their upper end is respectively equipped with perpendicular horizontal cylindrical void, and they are benchmark with vertical cylindrical void separately, with being located at a direction, (promptly with being located at the cylindrical void left side or being located at the cylindrical void right side together).Be provided with pole spar in above-mentioned connecting rod, its top is provided with and the cooresponding horizontal through hole of the vertical through hole of connecting rod; The minor diameter place that bearing pin two ends in it are passed the vertical through hole of connecting rod respectively and are fixed in the handle lower semisphere.This is enclosed within the end that handle lower semisphere on the connecting rod is built-in with spring, and the upper end of this spring is positioned at the handle episphere.When gripping the handle lower semisphere, to carry on pole spar is synchronous thereupon, the connecting leg of locations is left in its lower end, promptly leaves zero-bit and can operate.When feeling inconvenience, can when gripping the handle lower semisphere, rotate, bearing pin is entered in the horizontal cylindrical void of connecting rod, mention the position, eliminate the zero-bit self-locking so the handle lower semisphere is fixed on as frequent operation.
Be being connected of contact assembly and permanent seat that bayonet lock in the permanent seat and spring leaf realize by being located at, promptly respectively establish a high outside and low outside recessed groove in the inboard of permanent seat two pillar through holes, all establish a bayonet lock in each groove, their lower end is movably connected on the permanent seat by little axle, their upper end is a free end, shape such as arrow, both sides all have hook.In the space between two bayonet locks, two ends are set all spring leaf with the corresponding crotch of bayonet lock, and it both can make things convenient for the plug of contact assembly again with two bayonet locks location.
Radially the plug-in type cam bit is equipped with the radial opening groove, and this open slot width is a bit larger tham the camshaft length of side, the open slot degree of depth=cam radius+1/2 camshaft length of side.Be provided with screw in the open slot bottom, it is corresponding with the through hole on the camshaft, cam bit can be fixed on the camshaft by screw.This structure can change deciliter program of contact easily.
Frame is to be formed by support and two split unit constructions of flange fixed thereon.This minute body structure have a rest processing, precision height.
Automatic reset mechanism is provided with two adapter plates, is provided with pillar between them.This connection mode can prolong the service life of automatic reset mechanism.
The utility model has following advantage compared to existing technology:
1, cam bit is a plug-in type, not only without complete machine dismounting can single repair and replacement, change deciliter program of contact easily, face and guaranteed rigging position accurately, again the saving of labor, save time.
2, spring leaf has been set up in the grafting of contact assembly and permanent seat, make contact assembly plug-in mounting and choose freely, harmless.
3, joystick leaves the fixed mechanism of zero-bit, can alleviate operator's fatigue.
4, automatic reset mechanism is provided with two adapter plates that linked to each other by pillar, and it can prolong the service life of Bringing-back mechanism, makes its performance more reliable.
5, the contact mounted panel is made by transparent material, easily assembles, easily watches the internal actions situation.
6, split frame has been simplified the processing technology of frame, has improved working accuracy, also cuts down finished cost greatly simultaneously.
7, this master controller also can install potential device, coder etc. additional, is used for frequency control or stator voltage controlling system.
