Background
At present, as ships are developed in a large scale, a hoisting device for shipbuilding, i.e., a large shipbuilding gantry crane, is in greater demand. Due to the fact that the span of the large shipbuilding portal crane is very large, the crane main beam is directly connected with the flexible supporting legs, the flexible supporting legs can generate large bending moment and torque, and the rail clamping phenomenon occurs in the operation process of the large shipbuilding portal crane.
Disclosure of Invention
An object of the utility model is to provide a flexible hinge of large-scale gantry crane for shipbuilding to the above-mentioned problem that exists among the prior art.
In order to achieve the above object, the technical solution of the present invention is: the utility model provides a flexible hinge for large-scale gantry crane of shipbuilding, includes pressure-bearing rubber slab, basin seat and piston, in the pelvic cavity of basin seat was arranged in to the pressure-bearing rubber slab, pressure-bearing rubber slab top was provided with middle steel sheet, middle steel sheet top be provided with the recess, this middle steel sheet top recess is embedded to have the plane to rotate the antifriction plate, the piston arrange basin seat top and piston lower part in the pelvic cavity of basin seat in, the piston bottom is provided with corrosion resistant plate, the corrosion resistant plate and the plane of piston bottom rotate the antifriction plate and cooperate.
And a rubber sealing ring is arranged between the piston and the basin seat.
A sealing copper ring is arranged between the pressure-bearing rubber plate and the basin cavity of the basin seat.
Compared with the prior art, the beneficial effects of the utility model are that:
the flexible hinge has compact structure, flexible rotation, convenient installation and long service life, is arranged between a crane main beam and a flexible supporting leg, has the functions of horizontal rotation, vertical rotation, horizontal limit and compression resistance and has certain functions of vibration reduction and energy absorption; the problems of large bending moment and torque and crane running rail clamping caused by direct connection of the crane main beam and the flexible supporting legs can be solved.

Detailed Description
The invention is described in further detail below with reference to the following description of the drawings and the detailed description.
Referring to fig. 1 to 4, a flexible hinge of a large portal crane for shipbuilding includes a pressure-bearing rubber plate 1, a bowl base 2 and a piston 7. Pressure-bearing rubber plate 1 is arranged in the pelvic cavity of basin seat 2, and 1 top of pressure-bearing rubber plate is provided with middle steel sheet 5, 5 tops of middle steel sheet be provided with the recess, this 5 top recesses of middle steel sheet have plane rotation antifriction plate 6 to embed. The piston 7 is arranged above the basin seat 2, the lower part of the piston 7 is positioned in the basin cavity of the basin seat 2, and the bottom of the piston 7 is provided with a stainless steel plate 8; the stainless steel plate 8 at the bottom of the piston 7 is matched with the plane rotating wear-resisting plate 6, so that the horizontal rotation of the flexible hinge is realized, and the stainless steel plate 8 is a mirror surface stainless steel plate, so that the friction coefficient between the stainless steel plate 8 and the plane rotating wear-resisting plate 6 is very low, and the flexible hinge can freely rotate horizontally when bearing large vertical pressure.
Referring to fig. 1 to 4, a rubber sealing ring 4 is arranged between the piston 7 and the basin seat 2.
Referring to fig. 1 to 4, a sealing copper ring 3 is arranged between the pressure-bearing rubber plate 1 and the basin cavity of the basin seat 2.
Referring to fig. 1 to 4, the piston 7 and the stainless steel plate 8 are welded to form a piston assembly.
Referring to fig. 1 to 4, the overall structure of the flexible hinge is divided into four parts: horizontal rotating-structure, vertical rotating-structure, horizontal limit structure and compressive structures. The piston assembly and the plane rotation wear-resisting plate 6 in the flexible hinge form a horizontal rotation structure, and the horizontal rotation function is realized; the middle steel plate 5, the pressure-bearing rubber plate 1, the sealing copper ring 3 and the basin seat 2 form a vertical rotating structure, and the vertical rotating structure achieves a vertical rotating function; the piston assembly and the basin seat 2 form a transverse horizontal limiting structure which realizes the transverse horizontal limiting function; piston assembly, plane rotation antifriction plate 6, middle steel sheet 5, pressure-bearing rubber slab 1 and basin seat 2 constitute resistance to compression structure, and it realizes the resistance to compression function.
Referring to fig. 1 to 4, the flexible mounting structure is flexibly mounted between a crane main beam and a flexible supporting leg, has horizontal rotation, vertical rotation, horizontal limiting and pressure resisting functions and certain vibration damping and energy absorbing functions, and accordingly solves the problems of large bending moment, large torque and crane running rail clamping caused by direct connection of the crane main beam and the flexible supporting leg. The top of the piston assembly and the bottom of the basin seat 2 are made into circular boss structures and are respectively clamped into the holes of the crane main beam and the flexible supporting leg, so that the installation can be completed, and the installation is very convenient.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, above-mentioned structure should all be regarded as belonging to the utility model discloses a protection scope.
