Embodiment 1

[0041] As a basic embodiment of the present invention, the present invention includes a method for assembling a reel and a reel shaft of a large ship lift, comprising the following steps:

[0042] S 1 . The reel 1 is positioned horizontally; along the assembly direction of the reel shaft 2, the reel 1 includes an input end and an output end.

[0043] S 2 . Assemble the horizontal displacement hanging beam 3 inside the drum 1, and install two sets of heating devices 4.

[0044] S 3 . The first stage assembly of the reel shaft 2: use the external force to push the reel shaft 2 from the input end of the reel 1 into the inside of the reel 1, so that the end of the reel shaft 2 is close to the inner hole of the reel at the output end, even if the reel shaft 2 Most of the spools are assembled inside the reel 1, and the adjustment makes the reel shaft 2 and the center of the inner hole of the reel the same.

[0045] S 4 . Install the cooling device 6 on the two mating sections o...

Embodiment 2

[0049] As the best embodiment of the present invention, the present invention includes a method for assembling a reel and a reel shaft of a large ship lift, comprising the following steps:

[0050] S 1 . With reel 1 in place horizontally, fix reel 1 on tool support 7 that prevents reel 1 from rotating. Refer to the manual attached Figure 4 , On the webs at both ends of the reel 1, the circular holes for blanking are arranged vertically, and the upper and lower holes pass through the axis line. Along the assembly direction of the reel shaft 2, the reel 1 includes an input end and an output end, the reel inner hole on the input end is a large hole, and the reel inner hole on the output end is a small hole.

[0051] S 2 . Assemble the horizontal displacement hanging beam 3 inside the drum 1, that is, after the drum 1 is fixed vertically and horizontally adjusted and aligned, install the movable horizontal displacement hanging beam 3, and the horizontal displacement hanging be...

Abstract

The invention relates to the technical field of ship lift engineering, in particular to a method for assembling a winding drum and a winding drum shaft of a large ship lift. Assembling a horizontal displacement hanging beam in the winding drum, and installing two groups of heating devices; first-stage assembly of a drum shaft; mounting a cooling device and a horizontal driving device; the cooling device and the heating device work at the same time, after the preset temperature and time are reached, the cooling device and the heating device are dismantled, and the centering consistency of the winding drum shaft and the winding drum inner hole is checked and rechecked; a horizontal driving device horizontally moves the winding drum shaft, interference fit is converted into clearance fit, and the winding drum shaft is assembled in place; and cooling and inspecting to be qualified to finish the assembly. By means of the assembling method, the problem that in the prior art, hoisting turning-over safety risks exist can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of ship lift engineering, in particular to a method for assembling a drum and a drum shaft of a large ship lift. Background technique [0002] A ship lift is a navigable structure that uses a mechanical device to lift a ship to overcome the concentrated water level drop on the channel. The drum device is the key executive component of the main lifting mechanism of the wire rope lift ship lift. At present, the reel device is divided into two types: hoisting reel and safety reel. The safety reel is not directly connected to the driving mechanism. Its main function is to balance the weight of the carriage and the counterweight through the wire rope, and to add a braking system. Improve the braking capacity of the main hoist. [0003] At present, the hoisting drum and safety drum device used in large ship lifts are in the form of through shafts supported at both ends, and the drum shaft is a whole forged stepp...
