Abstract
The utility model relates to a control device for lower limited positions of a marine platform crane, which comprises a bracket. One end of the bracket is hinged with a pulley carrier of a lifting system through a pin, the other end of the bracket is provided with two steel wire rope guide wheels which are opposite to each other vertical and a counterweight wheel, a steel wire steel rope of a lifting system penetrates through the two steel wire rope guide wheels, an electromagnetic inductive switch is arranged above the pin, a baffle is fixed on the bracket, the upper end of the baffle contacts with the electromagnetic inductive switch, a spring is connected between the lower end of the baffle and the pulley carrier, and the electromagnetic inductive switch is connected with a control system. Multiple lower limited positions of the crane can be set automatically at any height through the control device. An alarm can be given or a winch brakes automatically when a pulley and a hook touch the surface of an obstacle, so that security and reliability of equipment are effectively increased and damage caused by over line casting of the winch is avoided.
Description
Technical field
The utility model belongs to the offshore oil machinery equipment technical field, relates to a kind of platform loop wheel machine lower limit control setup.
Background technology
Platform loop wheel machine and all kinds of ocean engineering boats and ships loop wheel machine are the major equipments of marine oil engineering and ocean engineering, as a kind of special ocean lifting appliance, platform loop wheel machine and all kinds of ocean engineering boats and ships loop wheel machine have higher reliability and security requirement.Existing platform loop wheel machine and boats and ships loop wheel machine are set a lower limit position usually, its deficiency is when crane trolley and suspension hook touch the obstacle surface respectively at various height, operating personal can't in time be discovered, and loop wheel machine elevator system winch easily takes place can not in time stop and cause winch excessively to put rope, winch cable problem such as to explain by oneself.
Summary of the invention
The purpose of this utility model provides a kind of platform loop wheel machine lower limit control setup, solved in the prior art platform loop wheel machine because of coaster with after suspension hook contacts the obstacle surface at various height, the elevator system winch continues the problem of excessively putting rope.
The technical scheme that the utility model adopted is, a kind of platform loop wheel machine lower limit control setup, comprise support, one end of support is hinged by the pulley bracket of bearing pin and elevator system, the other end of support is provided with relative up and down two steel rope guide wheels and weight wheel, be installed with the steel rope of elevator system among two steel rope guide wheels, the top of bearing pin is provided with the electromagnetic type inductive switch, be fixed with baffle plate on the support, the upper end of baffle plate contacts with the electromagnetic type inductive switch, be connected with spring between the lower end of baffle plate and the pulley bracket, the electromagnetic type inductive switch is connected with control system.
Platform loop wheel machine lower limit control setup of the present utility model, its feature also is: described support is connected with the baffle plate of arc by set pin.Described weight wheel is provided with this end oblique upper distal-most end of support.
The beneficial effects of the utility model are, realized that loop wheel machine is in a plurality of lower limit of any highly automated setting position, can report to the police in the obstacle surface or winch self-actuating brake braking when coaster and suspension hook are run into, actv. has increased the safety and the reliability of equipment, avoids causing damage because winch is excessively put rope.
Description of drawings
Fig. 1 is the structural representation of the utility model device.
Among the figure, 1. weight is taken turns, 2. support, 3. steel rope guide wheel, 4. baffle plate, 5. electromagnetic type inductive switch, 6. pulley bracket, 7. bearing pin, 8. spring, 9. steel rope, 10. set pin.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, the structure of the utility model device is, comprise support 2, one end of support 2 is hinged with the pulley bracket 6 of elevator system by bearing pin 7, the other end of support 2 is provided with relative up and down two steel rope guide wheels 3 and weight wheel 1, weight wheel 1 is provided with support 2 these end oblique upper distal-most end, be installed with the steel rope 9 of elevator system among two steel rope guide wheels 3, the top of bearing pin 7 is provided with electromagnetic type inductive switch 5, support 2 is connected with the baffle plate 4 of arc by set pin 10, the upper end of baffle plate 4 contacts with electromagnetic type inductive switch 5, is connected with spring 8 between the lower end of baffle plate 4 and the pulley bracket 6, and electromagnetic type inductive switch 5 is connected with control system.
Support 2 can be that the certain amplitude rotation is carried out in the axle center with bearing pin 7; The weight of weight wheel 1, distance and spring 8 are set all through preestablishing the suitable moment of bearing pin 7 generations relatively, this moment deficiency is so that steel rope departs from initial position when the tensioning of elevator system steel rope, and can make steel rope produce big offset deviation when steel rope is lax.
Weight wheel 1 and bearing pin 7 all are positioned at the same side of steel rope, and its line and steel rope gravity direction all have certain angle in 0 ~ 90 ° of luffing scope.
The principle of work of the utility model device is, electromagnetic type inductive switch 5 and baffle plate 4 that bearing pin 7 tops are provided with, formed the acquisition of signal part, baffle plate 4 set positions are in electromagnetic type inductive switch 5 induction ranges, loop wheel machine elevator system steel rope can change at tensioning state and its relative position of relaxed state, can produce certain offset deviation amount, relaxing can appear in the elevator system steel rope after crane trolley and suspension hook touched the obstacle surface, support 2, guide wheel 3 can be the centre of gration rotation with bearing pin 7 with steel rope, support 2 meeting drive baffle plates 4 rotate and make baffle plate 4 away from electromagnetic type inductive switch 5 simultaneously, exceed the induction range of sensor 5 when baffle plate 4 after, electromagnetic type inductive switch 5 will amplify and catch this offset deviation and be translated into electric signal again, and handle PLC by data conductor 6 biographies to loop wheel machine central authorities and realize loop wheel machine control, thereby solution elevator system winch is excessively put the rope problem.
Device of the present utility model not only can be applicable to all kinds of platform loop wheel machines, can also be applied in widely on harbour loop wheel machine, the ocean engineering boats and ships loop wheel machine, after can making Platform lifting devices coaster and suspension hook touch the obstacle surface at an arbitrary position,, winch avoids preventing and treating the situation of excessively putting rope thereby stopping immediately.
