Abstract
The invention provides an automatic power supply device used for a tyre-typed container gantry crane; a platform which is arranged on the upper surface of the tyre-typed container gantry crane is provided with a supporting rod; the lower end of the supporting rod is connected with the platform and the upper end thereof is connected with a pantograph; the pantograph contacts with an overhead slide-contact wire; the middle part of the supporting rod is connected with one end of a spring and the other end of the spring is connected on the platform; the supporting rod is connected with one end of an electro-hydraulic pushing rod by a waist-shaped hole; the other end of the electro-hydraulic pushing rod is connected on the platform. The automatic power supply device can continuously and stably supplies power for the operation of the tyre-typed container gantry crane, and can overcome the shortage of upper/lower shaking and offsetting to the left side and right side of the tyre-typed container gantry crane during the operation process; the pantograph can realize the automatic contact and disconnection with the DC bus by the electro-hydraulic pushing rod and the spring and can realize the free rotation field by 0 and 90 degree of the tyre-typed container gantry crane. The automatic power supply device can be applied to electric-driven tyre-typed container gantry crane and can achieve the requirement on flexibility and safety performance during the operation process.
Description
Technical field
The invention belongs to the power supply mode field of moving contact, specially refer to the automatic power supply device of the tire type gantry crane of electric energy is provided with electrically operated rubbertyred container gantry crane.
Background technology
Along with the constantly bringing forth new ideas and develop of harbour machinery theory and technology, the up-to-date technology of many environmental protections has obtained application at the harbour, is that the rubbertyred container gantry crane of power has been applied in many harbours with the electric energy of clean environment firendly wherein.Yet these rubbertyred container gantry cranes that use electric energy can not be realized freely cutting to all because of the restriction of power supply mode at present, thereby the advantage flexible, that can freely cut to of rubbertyred container gantry crane is completely lost.
The power supply mode of the electric means of the applied built on stilts contact suspension of light rail train and electric car of public traffic is very ripe now, widespread use in daily life.Can improve existing rubbertyred container gantry crane power supply mode under the guidance of these technical backgrounds, guaranteeing provides electric energy continually and steadily, and rubbertyred container gantry crane can freely be cut to, and still has flexible characteristics.
Summary of the invention
The automatic power supply device that the purpose of this invention is to provide a kind of rubbertyred container gantry crane, reach the power supply mode of improving power-actuated rubbertyred container gantry crane, the electric energy that provides that it can be continual and steady is provided, and can freely cuts to, the efficient of raising port operation.
Particular content of the present invention is:
A kind of automatic power supply device of rubbertyred container gantry crane, it is characterized in that: the platform on rubbertyred container gantry crane is put on the shelf and is provided with strut bar, strut bar lower end moveable hinge is connected on the platform above the rubbertyred container gantry crane, post upper connects pantograph, pantograph contacts with overhead trolley, be connected with spring one end on the strut bar, the spring other end is connected on the platform above the rubbertyred container gantry crane, also be connected with an end of Electrohydraulic push rod on the strut bar, the other end of Electrohydraulic push rod is connected on the platform above the rubbertyred container gantry crane.
Be provided with above the hinge under current-collecting device and realize contacting automatically and open circuited Electrohydraulic push rod device with dc bus, the two ends of pantograph are provided with can correct the sideslip inductor that the rubbertyred container gantry crane sideslip guarantees continued power.
Advantage of the present invention is:
Improve the power supply mode of power-actuated tire type gantry crane, the electric energy that provides that it can be continual and steady is provided, and can freely cuts to, the efficient of raising port operation.

Among the figure: 1. overhead trolley 2. pantographs 3. strut bars 4. springs 5. Electrohydraulic push rods 6. are erected at rubbertyred container gantry crane platform 7. overhead trolley rope hoister 8. sideslip inductors 9. and connect twisted point 10. middle brace rods
The specific embodiment
The structure of the automatic power supply device of the rubbertyred container gantry crane shown in the figure comprises: pantograph, strut bar, Electrohydraulic push rod, spring installation, sideslip inductor.Each pantograph (2) is supported by two parallel strut bars (3), makes pantograph be close to trolley (1) power taking, and on the pantograph that zero line contacts sideslip inductor (8) is housed.Each strut bar one end connects pantograph, and the other end is connected with active wring point on the platform that is erected at rubbertyred container gantry crane on (6); Spring installation (4) one ends connect strut bar (or middle brace rod), and an end is fixed on the rubbertyred container gantry crane, and spring is in extended state all the time; Electrohydraulic push rod (5) one ends connect middle brace rod (10), and an end is fixed on the rubbertyred container gantry crane, and wherein the junction of Electrohydraulic push rod and middle brace rod is designed to waist-shaped hole.
During the rubbertyred container gantry crane operation, spring tension makes strut bar compress pantograph, and pantograph touches is with galvanic trolley.DC current enters a bridge power system through pantograph and cable, for the operation of gauntry crane provides necessary energy, connects other root trolley through another pantograph again, forms C/LOOP.During 0 degree transition, rubbertyred container gantry crane directly runs to the purpose stockyard along trolley and gets final product; During 90 degree transitions, Electrohydraulic push rod starts, and overcomes spring tension strut bar is descended, and pantograph breaks away from trolley.Rubbertyred container gantry crane provides power to run to the below of purpose stockyard trolley by generator set.After the contraposition, Electrohydraulic push rod return, strut bar raise up under the effect of spring tension and pantograph are contacted with trolley again, and circuit recloses.Wherein, waist shaped hole is made in the junction of strut bar and Electrohydraulic push rod, and Electrohydraulic push rod can slide in waist-shaped hole in the process of strut bar rise and fall.With on the pantograph that zero line contacts the sideslip inductor is installed, after rubbertyred container gantry crane walking off-straight exceeds the scope of permission, the inductor that is installed on the pantograph is given signal of control system, and control system realizes correction by the rotating speed of regulating left and right sides cargo motor.
