Embodiment Construction

[0019] The structure of the automatic power supply device of the rubber-tyred container gantry crane shown in the figure includes: a pantograph, a support rod, an electro-hydraulic push rod, a spring device, and a deviation sensor. Each pantograph (2) is supported by two parallel support rods (3), so that the pantograph is close to the trolley line (1) to take power, and the pantograph in contact with the neutral line is equipped with a deviation sensor ( 8). One end of each support rod is connected to the pantograph, and the other end is connected to the platform (6) erected on the rubber-tyred container gantry crane with a movable hinge point; one end of the spring device (4) is connected to the support rod (or intermediate connecting rod), and one end It is fixed on the rubber-tyred container gantry crane, and the spring is always in a stretched state; one end of the electro-hydraulic push rod (5) is connected to the middle connecting rod (10), and the other end is fixed on...

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 [0001] The invention belongs to the field of power supply modes of sliding contact, and in particular relates to an automatic power supply device of a rubber-tyred gantry crane that provides electric energy for an electrically driven rubber-tyred gantry crane. Background technique [0002] With the continuous innovation and development of port machinery theory and technology, many green and environmentally friendly new technologies have been applied in ports, among which rubber-tyred container gantry cranes powered by clean and environmentally friendly electric energy have been applied in many ports. However, at present, these rubber-tyred container gantry cranes that use electric energy cannot realize free transition due to the limitation of the power supply mode, so that the advantages of flexibility, convenience and free transition of the rubber-tyred container gantry crane are completely lost. [0003] The power receiving method of the overhead contact su...
