[0033] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0034] Example 1: A clinker burning grate cooling device, see Figures 1 to 4 , including a grate cooler body 1, a bottom plate 2 and a fan body 4;

[0035] A plurality of bottom plates 2 are fixedly arranged below the air outlet of the grate cooler body 1 in sequence; a plurality of fan bodies 4 are respectively positioned and matched with the plurality of bottom plates 2 through the mounting structure 3; wherein the fan body 4 is connected to the air outlet end flange of the grate cooler body 1 through the air duct 5;

[0036] The mounting structure 3 includes a mounting plate 301;

[0037] The mounting plate 301 is fixedly mounted on the bottom end of the fan body 4 ; wherein, both sides of the mounting plate 301 are respectively positioned and matched with the bottom plate 2 through positioning components 302 .

[0038] The utility model has the advantages of directly installing or removing the fan body 4 without tools by setting the installation plate 301 and the positioning assembly 302, which is more convenient and efficient to operate, and solves the problem that the installation method of multiple bolt positioning will consume more time when installing or removing the fan.

[0039] Specifically, the positioning assembly 302 includes an L-shaped plate 3021;

[0040] Two L-shaped plates 3021 are symmetrically fixed on the bottom plate 2; wherein, two movable rods 3022 are symmetrically penetrated through the horizontal section of the L-shaped plate 3021, and the bottom ends of the two movable rods 3022 are fixed with insertion strips 3023, which are plugged into the insertion holes 3012 opened on the bottom plate 2, and the top ends of the two movable rods 3022 are fixed with movable plates 3024, and the movable rods 3022 between the movable plates 3024 and the horizontal section of the L-shaped plate 3021 are sleeved with springs 3025; the two ends of the spring 3025 are respectively fixedly connected to the movable plate 3024 and the horizontal section of the L-shaped plate 3021, and the elastic coefficient of the spring 3025 is selected and used by technicians in this profession according to actual conditions.

[0041] The utility model has the advantages of simple structure, convenient operation and control for positioning the mounting plate 301, and short time consumption by arranging the L-shaped plate 3021, the movable rod 3022, the inserting strip 3023, the movable plate 3024 and the spring 3025.

[0042] Furthermore, the outer end of the movable plate 3024 extends outward relative to the horizontal section of the L-shaped plate 3021. The outwardly extending portion of the movable plate 3024 facilitates the staff to push the movable plate 3024 by hand, making it easier to exert force during operation.

[0043] Furthermore, two slide bars 3011 are symmetrically fixed on the bottom side of the mounting plate 301 , and two slide grooves 201 are symmetrically opened on the bottom plate 2 , and the slide grooves 201 are slidably matched with the slide bars 3011 ; the ends of the slide grooves 201 are closed, and the slide bars 3011 are adapted to the slide grooves 201 .

[0044] The utility model has the advantage of limiting the mounting plate 301 mounted on the bottom plate 2 by setting the slide bar 3011 and the slide groove 201, so that the mounting plate 301 is stably installed, and the mounting plate 301 is prevented from deviating from the travel direction and affecting the plugging of the insertion strip 3023 and the plug hole 3012.

[0045] Working principle: When using the device of the utility model to install the fan body 4, the staff pushes the outwardly extending parts of the two movable plates 3024 upward, the movable rod 3022 drives the insertion strip 3023 to move upward, the spring 3025 is compressed, and the suspended fan body 4 together with the mounting plate 301 is placed on the bottom plate 2 through the external lifting device, and the slide bar 301 is correspondingly inserted into the slide groove 201, and the fan body 4 and the mounting plate 301 are pushed until the slide bar 3011 is completely inserted into the slide groove 201 and does not move. At this time, the fan body 4 and the mounting plate 301 move to the designated installation position, and the movable plate 3024 is released. Under the action of the spring 3025, the movable rod 3022 drives the insertion strip 3023 to move downward until the insertion strip 3023 is inserted into the socket 3012 to position the mounting plate 301, thereby positioning the fan body 4; the air duct 5 is connected to the air outlet end flange of the grate cooler body 1.
