The invention discloses a tool for ship hydraulic nuts for horizontal lifting. The tool comprises a lifting plate, and a first lifting lug arranged on the lifting plate; lifting columns are symmetrically arranged on the lower surface of the lifting plate about the axis of the lifting plate; and bearing bolts matched with mounting holes on the outer walls of the hydraulic nuts are arranged at the tail ends of the lifting columns. The bearing bolts symmetrically arranged on the tool are inserted in the original mounting holes on the outer walls of the hydraulic nuts; the bearing bolts are connected with the lifting plate through the lifting columns; the first lifting lug is connected with the lifting plate; and lifting machinery is connected with the first lifting lug to directly perform horizontal lifting of the hydraulic nuts, so that the horizontal lifting stability of the hydraulic nuts is improved.

Example Embodiment

[0015] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and embodiments. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.
[0016] like figure 1 , 2 As shown, the present invention is a tool for horizontally hoisting hydraulic nuts for ships, comprising a hanging plate 1 and a first lifting lug 2 arranged on the hanging plate, and the lower surface of the hanging plate is symmetrically arranged with the hanging column 3 with the axis of the hanging plate , the end of the hanging column is provided with a load-bearing bolt 4 that matches the mounting hole of the outer wall of the hydraulic nut.
[0017] The central position of the hanging plate is provided with a circular central hole, a central column 5 is penetrated in the central hole, the upper end of the central column is provided with a second lifting lug 6, and the lower end of the central column is provided with four struts 7, three Each of the struts is hinged with the central column, and the struts are arranged in an annular array with the rotation axis of the central column as the center, and the length of the struts is greater than the inner diameter of the hydraulic nut.
[0018] The inner wall of the circular hole is provided with an annular groove, the annular groove 8 is provided with three balls 9, and the notch width of the annular groove is smaller than the diameter of the ball; The curved grooves 10 are evenly arranged, the axis of the curved grooves is parallel to the rotation axis of the central column, and the curved grooves are matched with the balls.
[0019] The infrared emitter 11 is disposed downward at the midpoint of the lower bottom surface of the central column.
[0020] The hanging column is a telescopic rod.
[0021] Four arc-shaped through holes 12 of equal length are circumferentially arranged on the hanger plate with the center of the hanger plate as the center of the circle, and the central angle of the arc-shaped through-holes is 70°; , the upper end of the hanging column is provided with a locking nut 13 .
[0022] A pressure rod 14 is arranged above the hanging plate, the pressure rod is vertical and connected to the central column, and hydraulic cylinders 15 are arranged vertically downward at both ends of the pressure rod. The top end of the piston rod of the hydraulic cylinder is connected to the The upper surface of the hanger plate interferes with the connection.
[0023] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the technical principles of the present invention, several improvements and modifications can be made. These improvements and modifications It should also be regarded as the protection scope of the present invention.
