Problems solved by technology

[0004] In order to solve the problem that the existing track crane must stop on the spot when one of the frequency converters or motors fails, which will affect the normal operation of other track cranes, the present invention provides a new control mode design The advanced track crane drive control system enables the whole machine to continue to run to the anchor parking space for maintenance in the failure mode, so as to avoid affecting other operating equipment in the workplace

Embodiment 1

[0026] Embodiment one, figure 1 It is a schematic diagram of the distribution positions of the motors of the middle cart of the rail crane proposed by the present invention, including eight cart motors 1 to 8, which are divided into two groups on average and installed on both sides of the cart respectively. In this embodiment, two cart inverters are used to drive and control the eight cart motors 1-8. In order to allow another cart inverter to continue to drive the remaining cart motors to drive the entire cart to the anchor parking space when a certain cart inverter or the cart motor controlled by it fails, this embodiment adopts a The inverter of one large cart simultaneously drives the two cart motors on both sides of the cart to run, and the remaining four cart motors are driven by another inverter of the cart, which is used to control the control core of the coordinated operation of the cart mechanism - the main controller of the cart. The system can still continue to ru...

Abstract

The invention discloses a track crane and a driving control system thereof. The driving control system comprises eight cart motors for driving a cart to run and two cart frequency converters for controlling the running of the cart motors, wherein the eight cart motors are averagely divided into two sets installed at both sides of the cart; one of the cart frequency converters simultaneously drives every two cart motors at both sides of the cart to run, the rest four cart motors are driven by the other cart frequency converter, and a cart master control system still continuously runs when the cart frequency converters are in a failure mode. When an electric circuit generates failures at the driven running part of a card mechanism, the driving control system of the track crane can move the track crane to the anchoring parking position of a working field in the failure mode, and then examines and repairs so that other track cranes running on the same track can continuously work, which indirectly improves the loading and unloading efficiency and fully ensures the running safety of the track crane.

Description

technical field [0001] The invention belongs to the technical field of lifting equipment, and in particular relates to a drive control system of a rail-type container gantry crane and a rail-type container gantry crane designed using the drive control system. Background technique [0002] Cranes play an extremely important role in the handling of containers in ports and terminals. For the rail-mounted container gantry cranes (usually referred to as rail cranes) commonly used on port terminals at present, the cart mechanism used to drive the whole machine and the trolley mechanism used to drive the lifting mechanism usually only have normal operation mode. That is, when the external conditions meet the design requirements, two sets of cart motors are driven by two cart inverters, and one cart inverter drives the cart motors on the same side of the rail crane; and it is used to drive the trolley mechanism The running four trolley motors can use two or four trolley inverters f...
