Problems solved by technology

In the existing operation mode, there is no feedback signal of the successful unlocking of the FTR lock by the spreader, which has seriously affected the operation efficiency due to the on-site operation experience. The driver of the gantry crane often needs the cooperation of the subordinate ropeman to meet a certain operation efficiency.

Embodiment Construction

[0011] The specific implementation manners of the present invention will be described in detail below, and the described embodiments are only illustrations and explanations of the present invention, and do not constitute the only limitation to the present invention.

[0012] Such as figure 1 Shown, the present invention comprises the following concrete steps:

[0013] Step 1, setting a laser distance measuring ruler in the horizontal and / or vertical direction on the spreader of the gantry crane traveling horizontally;

[0014] Step 2. The laser rangefinder includes a rangefinder rod and a laser rangefinder module arranged at a certain distance on the rangefinder rod, and each laser rangefinder module emits a laser detection signal and participates in the detection of the alignment container position;

[0015] Step 3: Through the feedback of each laser ranging module, it is quickly determined whether the FTR lock on the flatbed truck meets the unlocking conditions.

Abstract

The invention discloses a method for assisting a portal crane in quickly unlocking an FTR lock by adopting laser ranging rods. The laser ranging rods are arranged on a lifting appliance for transversely walking of the portal crane in the transverse direction and the longitudinal direction; the laser ranging rod comprises a ranging rod and laser ranging modules arranged on the ranging rod at certain intervals, and each laser ranging module emits a laser detection signal and participates in detection of the position aligned with the container; through the feedback of each laser ranging module, whether the FTR lock on the flat car has an unlocking condition or not is quickly judged. The method is simple in monitoring and quick in implementation, realizes quick loading and unloading operation of the portal crane, and improves the operation efficiency and the management effect of the portal crane. The patent comes from the science and technology research subject of the railway container intelligent station key technology research of the Chinese railway group limited company, and the subject number is N2020X009.

Description

technical field [0001] The invention belongs to the technical field of railway container crane hoisting, and in particular relates to a method for quickly unlocking an FTR of a gantry crane by using a laser distance measuring ruler. Background technique [0002] Gantry cranes have been widely used for hoisting operations, but in the existing operating system, when unloading flatbed trucks with FTR locks, most of the gantry cranes use manual assistance for alignment, and the operator will inform the driver of the gantry crane whether he has a spreader condition. And it is necessary to wait until the container is completely separated from the FTR before continuing to hoist. In the existing operation mode, there is no feedback signal of the successful unlocking of the FTR lock by the spreader, which has seriously affected the operation efficiency due to the on-site operation experience. The driver of the gantry crane often needs the cooperation of the subordinate ropeman to me...
