Description

Technical Field

[0001] The utility model relates to the field of dismantling devices, in particular to a dismantling device for a hydrogen oil sealing tile cover of a generator. Background Art

[0002] The stator of modern large-scale generator sets usually adopts hydrogen cooling, which has the advantages of small ventilation loss and high cooling efficiency. However, hydrogen has strong permeability, is easy to diffuse, and is flammable and explosive. When the volume concentration of hydrogen in the air reaches 4.0% to 74.2%, it is very easy to explode. Hydrogen-cooled generator sets use oil sealing tiles to separate the inside of the generator stator from the outside atmosphere, prevent hydrogen from leaking out of the machine or external air from entering the generator, and prevent hydrogen from mixing with air to cause fire or explosion accidents, ensuring the normal circulation of hydrogen and enabling the generator to obtain good cooling effect. Oil sealing tiles are key components of the hydrogen sealing system.

[0003] The existing Chinese patent announcement number is: CN201201216Y, which provides a hydrogen-cooled generator set sealing tile disassembly and assembly tool, including a handle and a cutter head with a threaded front end, the cutter head is coaxially mounted on a handle rod made at the front end of the handle, the handle rod coaxially made at the front end of the handle has a diameter smaller than the handle diameter, and an impact sleeve is coaxially slidably mounted on the handle rod. The utility model is a tool specially used for disassembly and assembly of hydrogen-cooled generator set sealing tiles, which is simple to manufacture, convenient and quick to use, and highly practical. The disassembly and assembly tool also has the advantages of improving construction efficiency and ensuring that the installation accuracy and coaxiality of the sealing tiles meet the construction requirements.

[0004] The above-mentioned disassembly and assembly tools also have the following problems during use: the above-mentioned disassembly and assembly tools need to be replaced by operating knobs or the like when replacing the cutter head, which results in a long time for replacing the cutter head, and there is a high possibility of accidentally injuring oneself when rotating the cutter head.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-6The generator hydrogen oil sealing tile cover removal device shown includes a handle 1, the handle 1 and the cutter head 4 are coaxially mounted on the handle rod 3, and the outer ring of the handle rod 3 is slidably mounted with an impact sleeve 2, and also includes:

[0029] The mounting assembly 5 has a mounting groove 51 at the front end of the handle bar 3, and a positioning block 52 is fixedly connected inside the mounting groove 51, and the positioning block 52 matches the positioning groove 53 reserved at the end of the cutter head 4;

[0030] The reinforcement component 6 has a slide groove 61 in the front end of the handle rod 3, and a slider 62 is movably connected to the inside of the slide groove 61 through a spring 64, and the end of the slider 62 matches a locking groove 63 reserved at the end of the cutter head 4, a pull rope 67 is fixedly connected to the end of the slider 62, and the pull rope 67 passes through a wire groove 68 reserved inside the handle rod 3 and is fixedly connected to the outer wall of a movable rod 69, and the movable rod 69 is slidably connected to a columnar groove 610 reserved inside the handle rod 3, and a pull ring 611 is fixedly connected to the end of the movable rod 69.

[0031] The end of the cutter head 4 is fully matched with the mounting groove 51, and the end wall of the cutter head 4 is in contact with the top wall of the mounting groove 51, which facilitates the fully matched installation of the cutter head 4 and the mounting groove 51. This ensures that there is no gap when the cutter head 4 and the handle rod 3 are installed, and also ensures the stability of the installation of the cutter head 4 and the handle rod 3.

[0032] One end of the spring 64 is fixedly connected to the end wall of the slider 62 which is always located in the slide groove 61, and the other end of the spring 64 is fixedly connected to the inner wall of the slide groove 61, which facilitates the reset movement of the slider 62. At the same time, the spring 64 pushes the slider 62 to match the engaging groove 63 to ensure the firmness of the installation of the cutter head 4 and the handle rod 3.

[0033] Four limit rods 65 distributed in a "mouth" shape are fixedly connected to the inner wall of each side slide groove 61, and the end of the limit rod 65 close to the slot opening of the slide groove 61 is always located inside the slide groove 61, and the outer wall of the limit rod 65 is in contact with and slidably connected to the inner wall of the limit groove 66 set through the inside of the slider 62, ensuring the stable movement of the slider 62.

[0034] The rope body connecting the pull rope 67 and the end wall of the slider 62 passes through the rod body on one side of the handle rod 3, so that the movement of the slider 62 can be adjusted through the pull rope 67 by toggling the movable rod 69.

[0035] The end of the movable rod 69 away from the pull ring 611 matches with the second engaging groove 612 reserved at the end of the cutter head 4, so that it is convenient for the movable rod 69 passing through the columnar groove 610 to limit the installation of the cutter head 4 and the handle rod 3.

[0036] Working principle: when using a generator hydrogen oil sealing tile cover removal device, first when the cutter head 4 needs to be replaced, the pull ring 611 is pulled to drive the movement of the movable rod 69 fixedly connected to the pull ring 611. When the movable rod 69 moves, the end of the movable rod 69 that originally matches the second engaging groove 612 reserved at the end of the cutter head 4 leaves the second engaging groove 612, and at the same time, the end of the movable rod 69 moves into the columnar groove 610. During the movement of the movable rod 69, the two pull ropes 67 fixedly connected to the outer wall of the movable rod 69 pull the slider 62 fixedly connected to the pull rope 67 to move in the slide groove 61. The limiting rod 65 fixedly connected to the inner wall of the slide groove 61 is movably connected to the limiting groove 66 reserved in the slider 62, so as to ensure the stability of the movement of the slider 62. At this time, the end of the slider 62 leaves the inside of the engaging groove 1 63 reserved at the end of the cutter head 4 that matches it. At this time, the handle rod 3 and the cutter head 4 can be easily separated without turning the knob, which is convenient and quick.

[0037] When the cutter head 4 is installed on the handle rod 3, the pull ring 611 is pulled in the same way as the above operation steps so that the slider 62 moves completely into the slide groove 61, and the side of the end of the cutter head 4 provided with the engaging groove 2 612 is aligned with the side of the handle rod 3 provided with the movable rod 69, and the positioning groove 53 is aligned with the positioning block 52, and then the cutter head 4 is installed into the installation groove 51 reserved in the handle rod 3, and the pull ring 611 is released. At this time, the spring 64 pushes the slider 62 to move and match the engaging groove 1 63, and the movable rod 69 moves synchronously through the columnar groove 610 and matches the engaging groove 2 612. This ensures the accuracy of the installation and does not cause misalignment. At the same time, the handle rod 3 and the cutter head 4 have three restrictive installations, which ensures that the handle rod 3 and the cutter head 4 are firmly installed. After the installation is completed, the end of the cutter head 4 of the device is aligned with the pin, and the pin can be installed by knocking the end of the handle 1 (the specific usage method is the same as the device usage principle in the comparative patent, which will not be repeated here).

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
