Description

Technical Field

[0001] The utility model relates to the technical field of grate plate installation, in particular to an installation tool for a fixed bed grate plate of a grate cooler. Background Art

[0002] Grate cooler is one of the important equipment for cement production. The grate plate is the key component for transferring heat and cooling cement. A grate cooler needs to be installed with hundreds to thousands of grate plates depending on its size. The grate bed of the grate cooler is of two forms: fixed bed and movable bed. The fixed bed is often made by casting. When installing the grate plates, a staggered splicing pre-assembly method is often adopted. However, after pre-assembly, the grate plates are heavy and difficult to carry from the ground to the grate bed. Therefore, after assembly, they need to be transported to the top of the fixed bed by hoisting for installation. The hoisting operation steps are complicated, resulting in low work efficiency and certain safety risks. Therefore, it is urgent to design a grate plate installation tool. Utility Model Content

[0033] Since it is difficult to carry the pre-assembled grate plate from the ground to the grate bed, a lifting tool is required for auxiliary transportation, and the operation steps are complex, resulting in low work efficiency and certain safety risks.

[0034] In view of this, as Figures 1 to 3 shown, this solution provides an installation tool for the grate plate of the fixed bed of the grate cooler, including a positioning component 100;

[0035] The positioning component 100 includes a positioning beam 110 and an auxiliary beam 120;

[0036] The positioning beam 110 is arranged below the auxiliary beam 120;

[0037] Multiple protrusions that cooperate with the grate plate 200 are arranged on the upper part of the positioning beam 110;

[0038] The spacing between the protrusions is set according to the size of the grate plate 200.

[0039] Specifically, Figure 3 as shown in the figure, when the grate plate 200 is in the state of facing upwards, a set of screw holes and long holes are arranged on each of the left and right sides for connecting the grate plates 200, and a counterbore and a slotted hole are arranged at each of the upper and lower ends. The protrusions on the positioning beam 110 can be set according to the size of the counterbore or the size of the slotted hole, so as to accurately position the spacing between the grate plates 200; the positioning beam 110 can be made of angle steel, and the side wall of the angle steel is used to abut against the grate plate 200 to achieve positioning, or it can be made by welding two steel plates at a 90° angle.

[0040] As Figure 1 shown, this tool can be directly placed on the upper surface of the grate bed or the upper surface of the already installed grate plate 200 for pre-assembly of the grate plate 200. The specific method is as follows:

[0041] Invert multiple grate plates on the auxiliary beam 120, evenly place the grate plates according to the points on the grate plates that cooperate with the protrusions, and then use bolts and nuts to connect according to the corresponding spacing; after the pre-assembled grate plates are connected, the grate plates can be removed and directly installed on the grate bed, which saves time and effort, avoids frequent lifting operations, and improves the installation efficiency.

[0042] Regarding the shape and structure of the support component 300 as Figure 1 and Figure 2 shown:

[0043] Two support components 300 are respectively arranged on both sides of the positioning component 100;

[0044] The support component 300 includes a connecting rod 310, a base 320, a support rod 330 and a bolt and nut pair 340;

[0045] One end of the connecting rod 310 is rotatably connected to the base 320 through a rotating shaft 350, and the other end is rotatably connected to a bolt-nut pair;

[0046] The support rod 330 is threadedly connected to the bolt-nut pair;

[0047] The connecting rod 310 is fixedly connected to the positioning beam 110 and the auxiliary beam 120 respectively.

[0048] Specifically, since the grate bed has an inclination angle of about 5° to 15° depending on the size of the equipment, in order to ensure stability during use, the support assembly 300 is presented in the form of a tripod and is adapted to the angle of the grate bed as a whole by adjusting the position of the bolt-nut pair 340 on the support rod 330, the connection angle between the bolt-nut pair and the connecting rod 310, and the connection angle between the connecting rod 310 and the base 320; as Figure 1 shown, the support assembly 300 can be directly placed on the upper surface of the already installed grate plate 200 without a specific fixing method, and can be stably placed on the grate bed by relying on the gravity of the device and the pre-assembled grate plate 200 itself.

[0049] More preferably, in order to avoid damaging the surface of the grate plate 200 when the support assembly 300 is placed on the grate plate 200, causing damage to the coating of the grate plate 200 and affecting its service life, an anti-slip pad can be provided at the bottom of the support rod 330, and a rubber pad can be provided at the lower part of the base 320, so that the lower part of the support assembly 300 is in contact with the grate plate 200 with a soft material.

[0050] This solution has at least the following beneficial effects:

[0051] The traditional pre-assembled installation of the grate plate 200 requires auxiliary transportation by a lifting tool, which is complex in operation, low in work efficiency and has certain safety risks. To solve this problem, this solution designs an installation tool including a positioning component 100 and a support component 300. The positioning component 100 uses the protrusions to accurately cooperate with the hole positions on the grate plate 200 to achieve rapid positioning and pre-assembly of the grate plate 200; the support component 300 adapts to grate beds with different inclination angles by adjusting the angles of the support rod 330 and the connecting rod 310 to ensure stability during the installation process. Using this tool, the grate plate 200 can be directly pre-assembled on the grate bed, saving time and effort, reducing frequent lifting operations, and greatly improving the installation efficiency. In addition, this tool does not require a special fixing method and can be stably placed by relying on its own gravity, further improving the convenience and safety of the installation.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
