[0025] like Figures 1-4 As shown, the present invention provides a column foot mounting device suitable for a sintering pelletizing waste heat boiler. The device is mounted on a foundation 10 and is used to fix three column feet 11 of the sintering pelletizing waste heat boiler. The column feet 11 have threaded sections 12. The device includes two positioning plates 20, a connecting plate 30, and three threaded sleeves 40.

[0026] The two positioning plates 20 are respectively fixedly mounted on both sides of the foundation 10 along the longitudinal direction.

[0027] The connecting plate 30 is disposed transversely between the two positioning plates 20, with its ends connected to the two positioning plates 20. The connecting plate 30 has three longitudinally extending insertion holes 31 formed therein. The three insertion holes 31 correspond to the three column feet 11, and the diameter of the insertion holes 31 is larger than the diameter of the column feet 11.

[0028] The three threaded sleeves 40 are respectively mounted on the three column feet 11 and are threadedly connected to the column feet 11. The outer circumference of the threaded sleeve 40 is in sliding contact with the inner wall of the corresponding insertion hole 31. The bottom of the outer circumference of the threaded sleeve 40 is formed with an outwardly protruding annular blocking portion 41.

[0029] The specific installation process of this device is as follows:

[0030] First, the staff places the three threaded sleeves 40 directly below the three insertion holes 31 respectively.

[0031] Then, the staff uses the lifting equipment to lift the sintering pelletizing waste heat boiler to the top of the connecting plate 30, and then controls the sintering pelletizing waste heat boiler to descend until the three column feet 11 pass through the three insertion holes 31 and are inserted into the three threaded sleeves 40. At this time, the three column feet 11 are in contact with the foundation 10.

[0032] Next, the worker pushes the threaded sleeve 40 upward until it moves to the threaded section 12 on the column foot 11. The threaded sleeve 40 is then rotated and passed through the insertion hole 31. When the annular stopper 41 on the threaded sleeve 40 contacts the bottom of the connecting plate 30, the three column feet 11 of the sintering pelletizing waste heat boiler are fixed to the device.

[0033] The device has a simple structure, few operating steps, and is easy to install and construct.

[0034] In one embodiment, a positioning groove 21 extending laterally inward is formed on the front face of the positioning plate 20, and the inner wall of the positioning groove 21 is adapted to fit the connecting plate 30. A limit assembly 50 is provided on the positioning plate 20 to prevent the connecting plate 30 from escaping from the positioning groove 21.

[0035] In this embodiment, a front end surface of the positioning plate 20 is provided with an inwardly extending receiving groove 22 , the receiving groove 22 is communicated with the positioning groove 21 , and a downwardly extending guide hole is provided at the bottom of the receiving groove 22 .

[0036] The limiting assembly 50 includes a guide rod 51, a limiting plate 52, and a spring 53. The guide rod 51 is positioned within the guide hole and in sliding contact with the inner wall of the guide hole. The limiting plate 52 is fixedly mounted on the top of the guide rod 51 and contacts the outer end surface of the connecting plate 30. The spring 53 is sleeved onto the guide rod 51. The first end of the spring 53 is fixedly connected to the limiting plate 52, and the second end of the spring 53 is fixedly connected to the inner wall of the receiving groove 22. The spring 53 forces the limiting plate 52 to move closer to the connecting plate 30.

[0037] In the initial state, due to the action of the spring 53 , the limiting plate 52 contacts the connecting plate 30 , and the connecting plate 30 is fixed in the positioning groove 21 .

[0038] During subsequent frequent use, when the specifications and dimensions of the new sintering pellet waste heat boiler change, the positions and dimensions of the three column feet 11 will also change accordingly.

[0039] At this time, the staff can pull the limit plate 52 downward until the limit plate 52 is out of contact with the connecting plate 30, and then pull it outward to remove the connecting plate 30. At this time, the spring 53 is in a compressed state. Then, a new connecting plate 30 is taken out, and three sockets 31 of appropriate positions and sizes are machined on the new connecting plate 30. The two ends of the new connecting plate 30 are inserted into the two positioning grooves 21. The limit plate 52 is released. Under the action of the spring 53, the limit plate 52 contacts the new connecting plate 30, and the new connecting plate 30 is fixed in the positioning grooves 21. Subsequently, the three column feet 11 of the new sintering pellet waste heat boiler can be installed.

[0040] This design enables the device to be installed on the three column feet 11 of sintering pellet waste heat boilers of different sizes. The staff only needs to replace the connecting plate 30, which has better versatility.

[0041] In one embodiment, a handle 54 is fixedly mounted on the limiting plate 52 to facilitate the staff to control the movement of the limiting plate 52 .

[0042] In one embodiment, the positioning plate 20 is welded to the plurality of steel bars 13 on the foundation 10 .

[0043] In one embodiment, if the sintering pellet waste heat boiler needs to be fixed at this location for a long time, the staff can weld the threaded sleeve 40 and the connecting plate 30 together to further improve the overall stability.

[0044] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all points of view, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.

[0045] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
