In order to solve the technical problem, the utility model discloses take following technical scheme: a detection tool for a lining plate of an HP coal mill comprises a central limiting baffle ring, a lining plate supporting body, a base and a supporting column; the base is of a circular ring structure and is arranged on the periphery of the bottom of the central limiting baffle ring, and the inner side wall of the base is connected with the outer side wall of the central limiting baffle ring; the liner plate supporting body is of a conical ring structure with the diameter of the top larger than that of the bottom, the liner plate supporting body is arranged on the periphery of the top of the central limiting baffle ring, and the inner side wall of the liner plate supporting body is connected with the outer side wall of the central limiting baffle ring; the position of the joint of the inner side wall of the lining plate support body and the central limit baffle ring is lower than the position of the top of the central limit baffle ring; the lining plate support body is connected with the base through the supporting column.
Furthermore, the central limit baffle ring is of a cylindrical structure.
Furthermore, the lining plate support body is connected with the base through a plurality of support columns; the support columns are distributed on the periphery of the central limit baffle ring at equal intervals.
Furthermore, a groove body is arranged at the upper part of the central limit baffle ring; the tank body surrounds the central limit baffle ring for a circle; the groove bottom of the groove body and the upper surface of the lining plate supporting body are positioned in the same plane.
Furthermore, the periphery of the lining plate support body is provided with a baffle ring.
Furthermore, 40-60 lining plates are placed on the surface of the lining plate support body, and a gap of 5-6cm is reserved between the first lining plate and the last lining plate.
The utility model has the advantages that:
1) the utility model discloses welt supporter and central spacing fender ring constitute a bowl form structure, put the welt in the welt supporter surface of frock, arrange along the circumferencial direction, the directional centre of a circle of length direction encloses into the round, can inspect the welt fast.
2) In the lining plate placed on the surface of the lining plate support body, a gap is reserved between the first block and the last block, so that fine adjustment is facilitated.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a top view of the present invention.
Fig. 3 is a schematic view of the lining board of the present invention.
Detailed Description
The technical solution of the present invention will be described clearly and completely through the following detailed description.
Referring to fig. 1-3, the tool for inspecting the lining plate of the HP coal mill of the present invention comprises a central limit stop ring 1, a lining plate support body 2, a base 3 and a support column 4; the central limit baffle ring 1 is of a cylindrical structure. The base 3 is of a circular ring structure and is arranged on the periphery of the bottom of the central limiting baffle ring 1, and the inner side wall of the base is connected with the outer side wall of the central limiting baffle ring 1; the liner plate supporting body 2 is of a conical ring structure with the diameter of the top larger than that of the bottom, the liner plate supporting body 2 is arranged on the periphery of the top of the central limiting baffle ring 1, and the inner side wall of the liner plate supporting body is connected with the outer side wall of the central limiting baffle ring 1; the position of the joint of the inner side wall of the lining plate support body 2 and the central limit baffle ring 1 is lower than the position of the top of the central limit baffle ring 1. The periphery of the lining plate supporting body 2 is provided with a baffle ring 5. The lining plate support body 2 is connected with the base 3 through a plurality of support columns 4; the support columns 4 are distributed on the periphery of the central limit baffle ring 1 at equal intervals.
The upper part of the central limit baffle ring 1 of the utility model is provided with a groove body; the tank body surrounds the central limit baffle ring for 1 circle; the groove bottom of the groove body and the upper surface of the lining plate supporting body 2 are positioned in the same plane.
The surface of the lining board supporting body 2 of the utility model is provided with 40-60 lining boards, and a gap of 5-6cm is left between the first lining board and the last lining board.
