Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the limitations of the length of the power supply cable and the track of the existing rail-mounted gantry cranes, which prevent vertical transfer operations, and the fact that the tire-type gantry cranes are powered by diesel generators with high energy consumption, high noise, and high operating costs. The disadvantages of providing a power supply device for rubber-tyred gantry cranes

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] In Fig. 1, in a large cargo yard such as a container in a port terminal, a plurality of fixed brackets 1 arranged continuously are fixed. The current collector 2.2 in sliding contact with each trolley line 2.1 is fixedly installed on the upper part of the frame 3.1 of the trolley 3 which is located on the side of the trolley line 2 and can move in parallel with the trolley line 2.1; the lead wire 11 of the current collector 2.2 and the tire The electrical system of type gantry crane 7 is connected; one end of flexible traction rope 4 is connected on the vehicle frame 3.1 of dolly 3, and the other end is connected with the end that is fixed on the transverse pull rod 5 on tire type gantry crane 7 (referring to Fig. 2, image 3 , Figure 6 ).

[0025] The trolley 3 that moves parallel to the trolley line 2.1 can be on both sides of the t...

Abstract

A power supplying mechanism for tyre-type gantry crane is composed of fixed posts, power transmission lines arranged on said fixed posts, and sliding current collector able to slide on said power transmission lines, fixed to a carriage able to move parallelly to said power transmission lines and with leading out power cord connected electrically with the electric system of gantry crane. Said carriage is flexible connected to the gantry crane.

Description

technical field [0001] The invention belongs to a power supply device, in particular to a device used in a large cargo yard such as a port wharf to supply power to a rubber-tyred gantry crane. Background technique [0002] At present, there are basically two types of hoisting machinery in the large cargo yards of major terminals at home and abroad, especially gantry cranes dedicated to lifting containers: one is a tire-type gantry crane, and the other is a rail-type gantry crane. crane. [0003] The power of rail-mounted gantry cranes in the cargo yard on the wharf is powered by the power grid. The connection of the electrical system is that the collector directly fixed on the frame of the crane fuselage is in contact with the trolley line, and the power grid passes through the cable reel. It is connected with the trolley line, and the collector is connected with the electrical system of the crane. Because the high-current trolley line power supply method has relatively hi...
