Description

[Detailed description of the invention] (Technical field) The present invention relates to a mounting structure for a wear-resistant liner.
In particular, a wear-resistant liner that has a wear-resistant plate such as a ceramic plate on the surface and a liner bottom plate on the back side is made into a unit, and a plurality of liners (units) of a predetermined size are mounted on a predetermined mounting surface. The present invention relates to a structure for attaching the device in a state in which the device is connected to the device.

(Prior art) In recent years, transport materials (ore, crushed stone,
A wear-resistant liner that uses a wear-resistant plate of a predetermined size, such as a wear-resistant ceramic plate, has been developed as a liner that is attached to parts that are subject to wear due to impacts, friction, etc. caused by sand and earth, etc., and has been used in reality. It has been widely used, and its excellent wear and corrosion resistance properties have been demonstrated.

By the way, this type of wear-resistant liner is generally made of a ceramic plate or the like on the surface, as is generally seen in, for example, Japanese Utility Model Publication No. 54-36456, Japanese Utility Model Publication No. 55-22004, and furthermore, Japanese Utility Model Publication No. 59-4961. A plurality of wear-resistant plates are covered, and a liner bottom plate is provided on the back side. Preferably, the wear-resistant plates are supported by the liner bottom plate through a rubber cushion layer, so that the cushioning It also has a structure that provides soundproofing effects. In the case of such a wear-resistant liner, in order to attach it to the inner surface of the mounting wall of the intended hopper or chute, a bolt is planted on the back side of the liner, and this bolt is attached to the mounting wall. It has a fixed structure that is inserted into a bolt hole in the wall and tightened with a nut from the outside.

(Problem) However, with the mounting structure in which such a liner is fixed to the inner surface of the mounting wall via bolts protruding from the back surface, it is difficult to install or replace such a liner. Since the liner itself has a considerable weight, it is not easy to handle, and it is difficult to locate the mounting position on the wall inside the hopper or chute, which creates a poor working environment. It is extremely time consuming.

For example, current products of such wear-resistant liners include four
A bolt is inserted into an insertion hole provided on a predetermined mounting surface such as a hopper wall, and then tightened with a nut. Therefore, dimensional accuracy is required for such insertion holes and bolt placement positions, and if there is any deviation, it will be difficult or impossible to insert the bolt, and the liner This will cause a problem where it will not be possible to install the Furthermore, during installation work, the bolts located on the back side of the liner and the insertion holes on the mounting surface cannot be visually seen, making workability even worse.Moreover, the liner installation work area is in a poor environment, and mechanical It is difficult to use and must rely on human power, but since the liner itself is heavy, it takes time to hold and position the liner against the mounting wall inside the hopper or chute.

Moreover, such conventional wear-resistant liners
Since the bolts protrude a specified length from the bottom plate of the liner on the back side, they cannot be stacked, and they require space or space to store and transport, and are difficult to transport. is also inherent.

(Solution) The present invention has been developed in view of the above circumstances, and its purpose is to improve the ease of installation on a predetermined mounting surface of a wall such as a hopper or chute, and to reduce the work time. We are developing a wear-resistant liner that can shorten the installation time, improve the safety of the installation work, reduce the number of man-hours required to process the liner itself, lower costs, and facilitate replacement work. The purpose is to provide a mounting structure.

In order to achieve this purpose, the present invention uses a wear-resistant liner that has a wear-resistant plate of a predetermined size such as a ceramic plate on the front side and a liner bottom plate on the back side. In a structure for mounting a plurality of liners in a state in which they are interconnected to a predetermined mounting surface, the connecting edge of one of the liners to be connected is connected to a predetermined gap between the liner bottom plate and the mounting surface. A raised stepped structure is formed so that a liner is formed, while the connecting edge of the other liner to be connected is made up of substantially only the liner bottom plate over a predetermined width. Then, the exposed liner bottom plate portion is inserted into the gap between the liner bottom plate and the mounting surface formed by the stepped structure of the connecting edge of the one liner, and the two are overlapped. The abrasion resistant plate is provided on the surface of the head and is fixed to the mounting surface with a bolt separate from the liner through a bolt insertion hole provided so as to pass through the part. be.

(Function/Effect) As described above, the present invention unitizes abrasion resistant liners and uses a plurality of them to cover a predetermined mounting surface such as the inner wall of a hopper. The connecting edges of the liners have a stepped butt structure, and the connecting edges of one liner are overlapped with the connecting edges of the other liner, and they are overlapped using bolts with wear-resistant plates that are separate from the liners. Since the liner is used to fix the part to the mounting surface, it is difficult to use a relatively heavy liner.
There is no need to delicately move the bolts fixed on the back side to match the mounting holes on the mounting surface as in the past, and the work of connecting and fixing them is easy.
Because it is only necessary to fix the connecting edges, positioning of the liner is easy, and it is also much easier to attach the liner to the intended mounting surface, which saves significant work time. This makes it possible to shorten the process time, ensure work safety, and reduce the number of man-hours required for machining the mounting bolts and their insertion holes, resulting in lower costs. be.

(Examples) Hereinafter, in order to clarify the present invention more specifically, examples of the present invention will be described in detail based on the drawings.

First, in FIG.
is shown installed according to the present invention,
These liners 6 are arranged and attached to areas of the hopper wall 4 that are susceptible to wear, generally over the entire surface thereof.

Also, part of this liner 6 is shown in Figure 2.
As shown in FIG. 3, it generally has a predetermined size (flat area) and a predetermined thickness overall, and has a ceramic plate made of a ceramic material such as alumina porcelain on its surface. A plurality of wear-resistant plates such as 10 are arranged and provided on the entire surface, while a liner bottom plate 12 made of a metal material such as a steel plate is provided on the back side. The plurality of ceramic plates 10 and the liner bottom plate 12 are joined directly or indirectly,
Although they are considered to have an integral structure, they are generally joined through a cushion rubber layer 8, and the presence of such a cushion rubber layer 8 allows them to have a cushioning effect, a soundproofing effect, etc. There is.

By the way, such a wear-resistant liner 6 has a rectangular shape, as shown in FIGS. 3 and 4 as a whole, and as shown in enlarged views in FIGS. 5 and 6. The opposing ends are connected to each other so that they can be attached to a mounting surface such as the hopper wall 4, so that one of the connecting edges of the opposing ends is connected to the liner bottom plate 12 constituting it. It has a stepped structure in which the stepped portion 13 is raised so that a predetermined gap is formed between the hopper wall 4 and the hopper wall 4 (see FIGS. 4 and 5).

Further, the other connecting edge of the liner 6 has the ceramic plate 10 and the cushion rubber layer 8 removed over a predetermined width, so that it is substantially composed only of the liner bottom plate 12. The liner bottom plate portion 14 has an exposed portion.

When connecting a plurality of liners 6 having such a structure, as shown in FIGS. 3 and 4, one liner 6 is formed with a stepped structure 13 at the connecting edge. The exposed liner bottom plate portion 14 of the other liner 6 is inserted into the space between the hopper wall 4 and the bolts 16 and nuts 18 shown enlarged in FIG.
It may be fixed to the hopper wall 4 with.

This bolt 16 has a wear-resistant plate such as a ceramic plate 10 similar to the liner 6 on the surface of its head 20, and the ceramic plate 10 is flush with the surface of the liner 6. As such, it is joined to the bolt head 20 via a cushion rubber layer 8 of a predetermined thickness, forming an integral structure.

Further, the overlapping connecting edges of the liners 6, 6 through which the bolt 16 is inserted are arranged so that the bolt 1
Ceramic board 1 in a shape corresponding to the size of 6
0 and cushion rubber layer 8 are removed, and a circular bolt insertion hole 22 is provided in the exposed liner bottom plate 12 portion, while an exposed liner bottom plate portion 14 of a predetermined width at the connecting edge of the other liner 6 is removed. includes a guide portion 24 opening at the end thereof and a holding hole portion 2 in which the leg portion of the bolt 16 is positioned.
A slit 28 which is a bolt insertion hole consisting of 6 is formed.

Accordingly, such a liner 6 is generally positioned with respect to that which is located below.
A plurality of liners 6 will be connected one after another, but at that time, the reference liner (Fig. 3 and 4)
The lowermost one in the figure) is positioned and fixed to the hopper wall 4 using a bolt 30 having the same structure as the bolt 16, and using this as a reference, their connecting edges are sequentially overlapped as described above. In addition, by sequentially fixing the liners 6 to the hopper wall 4 with the bolts 16 and nuts 18, the installation of the plurality of liners 6 can be effectively realized simply by fixing the bolts at their connecting edges. It will be done.

During such installation, in this embodiment, the exposed liner bottom plate portion 14 of the liner on the insertion side (the uppermost one in FIGS. 3 and 4)
Connecting the stepped structure 13 in the inserted liner 6 (the center one in FIGS. 3 and 4) that is already fixed to the hopper inner wall 4 from where the bolt insertion hole is the slit 28. With the edges temporarily fixed to the hopper wall 4 with bolts 16 in advance, the connecting edges 14 of the liner 6 on the insertion side can be inserted and the connecting edges can be overlapped. Therefore, it is possible to improve the stability of attachment of the previously attached liner 6 to the hopper wall 4.

In addition, in a structure in which the liner 6 is attached to the inner surface of the hopper wall 4, which is the mounting surface, using such separate mounting bolts 16, the bolts installed on the back surface of the liner, which cannot be seen visually, are There is no need to move or position the liner 6 so that it fits into the bolt insertion hole in the hopper wall 4, but simply butts the exposed liner bottom plate portion 14 of the other liner 6 against the stepped portion 13 of one liner 6. If this is done, the bolt insertion hole 2 of the stepped portion 13 will naturally be closed.
2 and the slit 28 in the exposed liner bottom plate portion 14.
(Specifically, the holding hole portion 26) and the bolt insertion hole of the hopper wall 4 are made to coincide with each other, thereby effectively improving the installation workability. Moreover, since the installation work is facilitated in this way, the relatively heavy liner can be handled more safely even under adverse working conditions.

Furthermore, as shown in the example, by fixing the connecting edges of the liners 6, 6 that are overlapped with each other with bolts 16, the number of bolt attachment parts per liner 6 ( Here, the number of pieces (2 pieces) is reduced, thereby reducing the number of man-hours for assembling the hopper, and also effectively reducing the number of man-hours for processing such as forming an insertion hole in the hopper wall 4, which improves the mounting structure. There is an advantage that cost reduction can also be achieved.

Although one embodiment of the present invention has been specifically described above, the present invention is by no means to be construed as being limited to such specific example.
Various changes, modifications, improvements, etc. can be made based on the knowledge of those skilled in the art without departing from the spirit of the present invention, and the present invention includes such embodiments. ,
Also, it goes without saying.
