Abstract
The invention relates to a cable bridging device of a gantry crane, belonging to the technical field of ship repairing and building. The cable bridging device of the gantry crane comprises a fixed seat (1); the two ends of the fixed seat (1) are respectively provided with a bearing (2); a rotary tube (5) is arranged between the bearings (2) respectively positioned at the left side and the right side; a bearing outer ring pressing ring (3) and a bearing inner ring pressing ring (4) are arranged at the outer side of each bearing (2); each bearing outer ring pressing ring (3) is fixedly connected with the fixed seat (1) by a bolt; a guide sleeve (6) is arranged at the outer side of each bearing outer ring pressing ring (3); a filler pressing ring (7) and a filler (8) are arranged at the inner side of each guide sleeve (6). After the cable bridging device of the gantry crane is used, the drawing force and the frictional force of a cable can be greatly reduced when the gantry crane moves, so that seawater and rainwater are prevented from invading into the bridging device, the cable is effectively protected, and the service life of the cable is greatly prolonged.
Description
Technical field
The present invention relates to a kind of gauntry crane cable Overbridge device, belong to and build ship technical field.
Background technology
2#35500T and 4#35500T self discharging ship gauntry crane cable trunk, because of design reasons, need pass below position gantry crane rail and cable tube from ship, then around on gauntry crane cable drum, as shown in Figure 1.The design of original Overbridge device places a pipe below track, and cable passes from pipe.But shipowner proposes: will move forward and backward during gauntry crane work, through herein time, cable can rotate along with the movement of gauntry crane, one is that cable can stressed stretching, and cable even can be made to throw off from cable coupling box; Two is that electric cable rotary can produce and rubs with wearing cable tube, the time grown after can damage protection skin outside cable and then wearing and tearing cable; Three is at sea travelling, and seawater, rainwater also can residue in pipe, can corrode cable.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency; there is provided a kind of gauntry crane cable Overbridge device, it substantially reduces tensile force and the friction force of cable when gauntry crane moves, and can prevent seawater, rainwater from immersing Overbridge device; effectively protect cable, substantially prolongs the service life of cable.
The object of the present invention is achieved like this: a kind of gauntry crane cable Overbridge device, it comprises permanent seat, described permanent seat comprises tubular junction and axle bearing mount portion, described axle bearing mount portion is arranged at two ends, tubular junction left and right, bearing is provided with in described axle bearing mount portion, rotatable pipe is provided with between the bearing of the described left and right sides, described bearing arranged outside has outside race trim ring and bearing inner ring trim ring, described outside race trim ring is fixedly connected with axle bearing mount portion by bolt, described bearing inner ring trim ring arranged outside has orienting sleeve, filler pressing and filler is provided with inside described orienting sleeve, described filler is between filler pressing and bearing inner ring trim ring.
Compared with prior art, the present invention has following beneficial effect:
A kind of gauntry crane cable of the present invention Overbridge device, by assembling filler in its two ends orienting sleeve, not only can prevent seawater, rainwater from immersing rotatable pipe, play sealing function, and rotate with cable when cable can be made to rotate in rotatable pipe, reduce its Relative friction; Bearing is equipped with in addition before rotatable pipe and permanent seat; flexible rotation between the two; when gauntry crane moves through herein; the related cable of rotatable pipe rotates together; when cable can be made to turn to herein, suffered tensile force and friction force reduce to minimum; available protecting cable, extends cable service life.
