Embodiment Construction

[0018] like figure 1 , figure 2 , image 3 , Figure 4 As shown, an embodiment of an automatic centering system for a crane over the rail, the automatic centering system in this embodiment includes a detection body 3 installed at the butt end of the main vehicle rail 1 and a detection body 3 installed at the auxiliary vehicle during use. The rail-aligning sensor assembly 4 at the docking end of the track 2 is used to receive the detection signal sent when the rail-aligning sensor assembly is in contact with the detection body, and send an inching control signal to the auxiliary vehicle according to the received detection signal to adjust the alignment of the auxiliary vehicle. In the PLC of the rail position, the detection body here is an angle iron, and the rail-aligning sensor assembly 4 here includes a left rail-facing sensor 42 and a right rail-facing sensor 41, wherein the left and right rail-facing sensors are respectively located at On the left and right sides, the ...

Abstract

The invention discloses a hanging over rail of a crane and an automatic centering system of the hanging over rail. The hanging over rail comprises a detection body fixedly arranged on a butting end of one of a main car rail and an auxiliary car rail of the hanging over rail and a pair-rail sensor component which is fixedly arranged at a butting end of the other rail and is to be in contact with the detection body to send a detection signal, wherein a signal output end of the pair-rail sensor component is connected with a programmable logic controller (PLC); and the PLC is provided with a signal output end which sends an intermittent inch signal to a driving motor for driving the main car rail or the auxiliary car rail to move. By the automatic centering system, both the adjusting efficiency and precision of the centering of the main car rail and the auxiliary car rail are high; and the problem of low adjusting efficiency caused by manual hanging over rail centering adjusting at present can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery, and in particular relates to a crane over-rail, in particular to an automatic centering system on the crane over-rail for centering a main vehicle and an auxiliary vehicle. Background technique [0002] Crane over-rail cranes are mostly used in thermal power plants, nuclear power plants, aircraft manufacturers and manufacturers that need two cranes to automatically dock. Enter another track and work back and forth freely. The trolley or electric hoist placed on the track will lift the equipment from one track to another track to complete the lifting of the equipment. At present, the docking of the main car track and the auxiliary car track is mostly realized by manual operation, and the main car track and the auxiliary car track are fixed together by the track fixing device after the docking, so that the lifting mechanism can smoothly transition from the main car track to the auxiliary...
