[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the specification drawings and specific embodiments.

[0020] An embodiment of the present application discloses a flange hole cleaning device. Referring to Figure 1 , Figure 2 and Figure 3 , it includes a mounting base 1, a loading table 2 is bolted to the mounting base 1, a positioning column 3 for vertically inserting into the inner side of the flange is integrally fixed on the loading table 2, and a plurality of telescopic rods 4 for abutting against the inner wall of the flange are installed on the outer wall of the positioning column 3 along its circumferential direction. A mounting plate 5 is welded on the mounting base 1 above the loading table 2, an mounting disc 6 is vertically slidably arranged on the side of the mounting plate 5 close to the loading table 2, a plurality of cleaning rods 7 are arranged at intervals around the circumference of the mounting disc 6 on the side close to the loading table 2, and the cleaning rods 7 are slidably arranged on the mounting disc 6 along the radial direction of the mounting plate 5. A limiting member 8 for restricting the movement of the cleaning rod 7 is installed on the mounting disc 6, and a driving member 9 for driving the mounting disc 6 to move is installed on the mounting plate 5.

[0021] In the embodiment of the present application, the fitter installs the flange to be cleaned on the loading table 2 and adjusts the plurality of telescopic rods 4 so that they jointly abut against the inner wall of the flange; then moves and adjusts the plurality of cleaning rods 7 to align them with the plurality of flange holes on the flange one by one; finally, the driving member 9 can drive the mounting disc 6 to move downward so that the cleaning rods 7 penetrate into the flange holes for cleaning; after the cleaning is completed, the driving member 9 can drive the mounting disc 6 to move upward and replace the next flange. Compared with the cleaning method in the comparative document, a flange hole cleaning device of the present application can install and clean flanges of various model sizes, and has the effect of improving the versatility of the device.

[0022] Specifically, the telescopic rod 4 includes a mounting cylinder 41 and an extension rod 42. The mounting cylinder 41 is horizontally welded and fixed on the outer wall of the positioning column 3, one end of the extension rod 42 is threadedly connected into the mounting cylinder 41, and the other end of the extension rod 42 is movably abutted against the inner wall of the flange.

[0023] In the embodiment of the present application, by rotating the extension rod 42, it can move axially along the mounting cylinder 41 to abut against the inner wall of the flange.

[0024] To prevent the extension rod 42 from abrading the inner wall of the flange when it abuts against it, a flexible block 43 is sleeved on the end of the extension rod 42 away from the positioning post 3. The flexible block 43 can be made of flexible materials such as rubber.

[0025] Specifically, the limiting member 8 includes a limiting bolt 81. A strip-shaped hole 61 for the limiting bolt 81 to pass through is axially formed in the mounting disc 6 along its own radial direction. A threaded hole adapted to the size of the limiting bolt 81 is formed at one end of the cleaning rod 7 close to the mounting disc 6. After the limiting bolt 81 passes through the strip-shaped hole 61, it is threadedly connected in the threaded hole.

[0026] In the embodiment of the present application, a counterbore 62 for accommodating the nut of the limiting bolt 81 is also formed at the strip-shaped hole 61 on the mounting disc 6. The staff can loosen the cleaning rod 7 by rotating the limiting bolt 81, then slide and adjust the position of the cleaning rod 7 along the length direction of the strip-shaped hole 61, align the cleaning rod 7 with the flange hole of the lower flange, and finally tighten the limiting bolt 81 to firmly install the cleaning rod 7 on the mounting disc 6.

[0027] Refer to Figure 4 , the cleaning rod 7 includes a fixed rod 71 and a flexible cleaning block 72. The threaded hole is arranged on the fixed rod 71. The cleaning block 72 is coaxially sleeved on the outer wall of the fixed rod 71. The outer wall of the cleaning block 72 is a conical surface. The diameter of the side of the cleaning block 72 close to the mounting disc 6 is larger than the inner diameter of the flange hole, and the diameter of the side of the cleaning block 72 away from the mounting disc 6 is smaller than the inner diameter of the flange hole. A baffle 10 for restricting the cleaning block 72 from sliding axially along the fixed rod 71 is detachably connected to the end of the fixed rod 71 away from the mounting disc 6.

[0028] In the embodiment of the present application, the cleaning block 72 is made of sponge material. Since the cleaning block 72 is a flexible material, when passing through the flange hole, the cleaning block 72 can deform to completely contact and clean the flange hole. In addition, this design also enables the cleaning block 72 to clean flange holes with various inner diameters. The baffle 10 can prevent the cleaning block 72 from sliding out of the fixed rod 71 during the process of cleaning the flange hole. A screw is welded on one side of the baffle 10, and the screw is threadedly connected to the end of the fixed rod 71 away from the mounting disc 6. After the cleaning block 72 is used for a period of time, the baffle 10 can be rotated to detach the baffle 10 and replace the cleaning block 72.

[0029] Specifically, the driving member 9 includes a rocker 91 and a spring 92. A slide bar 93 is welded to the side of the mounting plate 6 away from the cleaning rod 7. One end of the slide bar 93 vertically passes through the mounting plate 5 and is integrally fixed with a fixed block 94. A through hole for the slide bar 93 to pass through is formed in the mounting plate 5. The spring 92 is sleeved on the slide bar 93 and is located between the mounting plate 5 and the mounting disc 6. The rocker 91 is vertically rotatably arranged on the mounting plate 5. A pull rope 95 is connected between one end of the rocker 91 and the fixed block 94. A handle 96 is welded to the other end of the rocker 91.

[0030] In the embodiment of the present application, one worker rotates the rocker 91 and lifts the mounting disc 6, and another worker can install the flange to be cleaned on the loading table 2 and align the cleaning rod 7 with the flange hole. Then, the rocker 91 is slowly released. Under the action of the self-weight of the mounting disc 6 and the elastic force of the spring 92, the cleaning rod 7 can move downward and penetrate into the flange hole for cleaning.

[0031] The implementation principle of a flange hole cleaning device in the embodiment of the present application is as follows: The tooling personnel install the flange to be cleaned on the loading table 2 and adjust a plurality of telescopic rods 4 so that they jointly abut against the inner side wall of the flange; then move and adjust a plurality of cleaning rods 7 to align them with a plurality of flange holes on the flange one by one; finally, the driving member 9 can be used to drive the mounting disc 6 to move downward so that the cleaning rod 7 penetrates into the flange hole for cleaning; after the cleaning is completed, the driving member 9 can be used to drive the mounting disc 6 to move upward and replace the next flange. Compared with the cleaning method in the comparative document, a flange hole cleaning device of the present application can install and clean flanges of various model sizes, and has the effect of improving the versatility of the device.
