Abstract
The utility model relates to a cam controller for a crane, which is characterized in that contact groups 1-8 are used for cutting off resistance in the A direction, contact groups 9 -16 are used for cutting off the resistance in the B direction, wherein contact groups 1 and 2 and contact groups 9 and 10 are uniform in separation and combination motions and used for cutting off the lowest resistance, and a motor is operated in a second gear at a low speed, contacts groups 3 and 4 and contact groups 11 and 12 are uniform in the separation and combination motions and are used for cutting off a lower resistance, the motor is operated in a third gear, contact groups 5 and 6 and contact groups 13 and 14 are uniform in the separation and combination motions and are used for cutting off a higher resistance, and the motor is operated in a fourth gear, and contact groups 7 and 8 and contact groups 15 and 16 are uniform in the separation and combination motions and are used for cutting off all resistance of a resistance box, and the motor is operated in a fifth gear. The cam controller for the crane omits a control cabinet formed by an alternating current contactor, an intermediate relay and a time relay and uses the cam controller to control the motor directly, thereby reducing failure rates of equipment and saving cost of equipment operation and maintenance.
Description
Technical field
The utility model belongs to the travelling facility technical field, specifically a kind of driving cam controller.
Background technology
The cam controller master is with the starting, speed governing, commutation, braking that are applied to motor in the hoisting device etc.Motor more than control 30KW, when especially control hoists motor, can not use cam controller directly to control motor, need to use cam controller control A.C. contactor, auxiliary reclay and the time relay to finish above-mentioned functions, this has increased equipment operation cost and operation troubles rate virtually, and output strip line fast at rhythm of production, work under bad environment seems particularly outstanding.
The utility model content
Because above-mentioned weak point, the purpose of this utility model provides a kind of driving cam controller, its technical design core is: on the basis of rack construction that does not change present cam controller and manufacturing process, improve the sets of contacts control of cam controller, deciliter realization by the cam controller sets of contacts is to the direct speed regulating control of the above motor of 30KW.The realization the technical solution of the utility model is: this driving cam controller, comprise guard shield, handwheel, camshaft and sets of contacts, it is characterized in that sets of contacts is reconfigured, change sets of contacts deciliter program, adopt the closed simultaneously function that realizes excising resistance, regulates electromotor velocity of two sets of contacts.In the commutation sets of contacts, use jumbo sets of contacts, directly control motor and commutate.And in the excision resistance loop, two cover sets of contacts are one group, be sets of contacts 1 and 2, sets of contacts 3 and 4, sets of contacts 5 and 6, sets of contacts 7 and 8, sets of contacts 9 and 10, sets of contacts 11 and 12, sets of contacts 13 and 14 and sets of contacts 15 and 16 be respectively one group, every group medial extremity short circuit wherein, outboard end connecting resistance case, sets of contacts 1-8 is the sets of contacts of direction A excision resistance, and sets of contacts 9-16 is the sets of contacts of direction B excision resistance.Wherein sets of contacts 1 and 2, sets of contacts 9 and 10 deciliter keep strokes, be used to excise lowest resistance value, motor is at 2 grades of low-speed runnings; Sets of contacts 3 and 4, sets of contacts 11 and 12 deciliter keep strokes are used for excision than low resistance, and motor is 3 grades of runnings; Sets of contacts 5 and 6, sets of contacts 13 and 14 deciliter keep strokes are used to excise higher resistance value, and motor is 4 grades of runnings; Sets of contacts 7 and 8, sets of contacts 15 and 16 deciliter keep strokes are used for resistance box resistance value complete resection, and motor runs up at 5 grades.
The utility model implements to have changed traditional high-power driving Motor Control mode and principle, remove the switch board that uses A.C. contactor, auxiliary reclay and the time relay to constitute, directly use cam controller control motor, not only reduce equipment failure rate, and saved equipment operation and maintenance cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 17, guard shield, 18, handwheel, 19, camshaft.
Embodiment
With reference to Fig. 1, the utility model is described further, this driving cam controller comprises guard shield 17, handwheel 18 and camshaft 19, it is characterized in that having abandoned being used for being used by A.C. contactor, auxiliary reclay and the time relay and form electrical control cabinet with cam controller, in the commutation sets of contacts, use jumbo sets of contacts, directly control motor and commutate.In the excision resistance loop, two cover sets of contacts are one group, be sets of contacts 1 and 2, sets of contacts 3 and 4, sets of contacts 5 and 6, sets of contacts 7 and 8, sets of contacts 9 and 10, sets of contacts 11 and 12, sets of contacts 13 and 14 and sets of contacts 15 and 16 be respectively one group, every group medial extremity short circuit wherein, outboard end connecting resistance case, sets of contacts 1-8 is the sets of contacts of direction A excision resistance, and sets of contacts 9-16 is the sets of contacts of direction B excision resistance.Wherein sets of contacts 1 and 2, sets of contacts 9 and 10 deciliter keep strokes, be used to excise lowest resistance value, motor is at 2 grades of low-speed runnings; Sets of contacts 3 and 4, sets of contacts 11 and 12 deciliter keep strokes are used for excision than low resistance, and motor is 3 grades of runnings; Sets of contacts 5 and 6, sets of contacts 13 and 14 deciliter keep strokes are used to excise higher resistance value, and motor is 4 grades of runnings; Sets of contacts 7 and 8, sets of contacts 15 and 16 deciliter keep strokes are used for resistance box resistance value complete resection, and motor runs up at 5 grades.
