Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1-3, an embodiment of the core package disassembling tool for a double-casing high-pressure boiler feed water pump of the present invention mainly supports the core package during the core package disassembling process, and includes a first slide 1 and two second slides 2 for supporting the core package, wherein the two second slides 2 are arranged in parallel, and the distance between the two second slides 2 is pre-calculated and set. The first slide way 1 and the two second slide ways 2 are respectively positioned at two sides of the core bag, so that supporting force is provided for two sides of the core bag, and the core bag 5 can be conveniently disassembled.

A support frame 11 is arranged below the first slideway 1, and the support frame 11 is connected with the first slideway 1 in a sliding way through a first pulley 12. The support frame 11 can be fixed on other planes through fastening bolt to guarantee the stability that first slide 1 set up, so that adjust the height of second slide 2 according to first slide 1, with the stability when guaranteeing that the core package is placed. The core bag 5 is slidably connected with the second slideway 2 through the second pulley 22, so that in the disassembling process, the on-site installation and debugging are facilitated through the matching of the first pulley 12 and the second pulley 22, and meanwhile, the overhaul period can be shortened, and the labor cost and the safety risk can be reduced. In order to reduce the friction force when the first pulley 12 and the second pulley 22 roll, rolling bearings are embedded in the first pulley 12 and the second pulley 22, so that the service lives of the first pulley 12 and the second pulley 22 are prolonged; while maintaining the smoothness of the movement of the first and

second pulleys

12 and 22.

The below of two second slides 2 all is provided with a plurality of support columns 21, and whole support columns 21 can realize going up and down in step through the linkage subassembly to guarantee that whole second slides 2 all are located same height, so that according to the height of core package 5's specification adjustment second slide 2, improve the variety of assembly and disassembly tools adaptation. The linkage assembly comprises a bottom column 41, a worm 43 and a plurality of worm wheels 42, wherein the worm 43 comprises a plurality of rod sections arranged along the axial direction of the worm 43, and the rod sections can be in one-to-one correspondence with the worm wheels 42 and are arranged in a matching way; thus, when the worm 43 is driven by a rotary member such as a servo motor, all the worm wheels 42 can be driven to rotate by the cooperation of the rod sections and the worm wheels 42. The bottom pillar 41 is located below the support pillar 21, the lower end portion of the support pillar 21 can be inserted into the bottom pillar 41, and the support pillar 21 and the bottom pillar 41 are screwed.
