品と交換される。2. Description of the Related Art As is well known, vibrating sieves have been widely used in various industries such as crushed stone, iron making, mining, cement and the like. Such a vibrating sieve mesh gradually wears due to the continuation of the sorting operation of the material to be sorted. As the abrasion of the net progresses, the sieves become larger and hinder the sorting function. When the abrasion of the net reaches a predetermined wear standard, the worn net is replaced with a new one.

決すべき課題があった。When replacing the mesh of the vibrating sieve according to the above conventional example, it is necessary to attach and detach the center bolt of the center fixing means. Must enter. As we all know,
The lower side of the net is a dangerous area where the space is generally small and it is difficult to secure a scaffold.Therefore, the workability is extremely poor and it takes a long time to replace the net. In order to prevent co-rotation, workers are required not only on the lower side of the net but also on the upper side of the net, and two workers are required. Was.

Since it is impossible to screwing the center bolt and nut, in hazardous locations is difficult to work, along with the removal of the nut and stud bolt by gouging, it is necessary to weld a new nut and stud bolt, until now From experience, this is by no means the preferred means.

円板状であっても何の支障もないものである。A bolt assembly having a configuration as shown in FIG. 1C , which is a fastening member, is inserted into and attached to the through holes 63, 63. The bolt assembly 64 includes a bolt 64a with six <br/> angle head, is fitted on the hexagonal head side of the bolt 64a, and a small-diameter lower seat gold 64b abuts in a counter network side of the supporting member, the small-diameter A large-diameter upper washer 64c fitted outside the lower washer 64b at a predetermined distance and pressed against the surface of the fixing plate 62 on the side opposite to the net, and a large-diameter upper washer 6 of the bolt 64a.
4c, a nut 65 for screwing the upper washer 64c, and a rotation, which is screwed and welded to the outside of the nut 65 and is a rotation preventing portion for preventing rotation by a spanner, for example. It is configured to include a prevention nut 64d. In this case, the bolt assembly 6
Using a hexagon Atamazuke bolt 64a to 4, but, this is not only utilizing a commercially available product. That is, since it is only necessary to have a retaining function, the head of the bolt may have a hexagonal hole or a simple disk shape without any problem.

６４の移動作業が容易になるという効果がある。If the outer diameter of the upper washer 64c is made larger than the inner diameter of the through hole 63a of the through hole 63, the lower washer 64 can be inserted simply by inserting the bolt assembly 64 into the through hole 63a.
The distance between b and the upper washer 64c is necessarily supported by the fixed plate 62.
Since it becomes the same as the dimension between the opposing surfaces with the member 61,
This has the effect of facilitating the operation of moving the bolt assembly 64 from the through hole 63a to the elongated hole 63b.

Even in this case, the upper and lower washers 64b and 64c are used. It is useful to prevent damage to the contact surfaces of the nut and bolt heads of the fixing plate 62 and the support member 61. Further, instead of the rotation preventing nut 64d, a parallel flat portion for hanging a wrench may be formed on the tip end side of the bolt 64a.

As shown in FIG. 2A, the mesh 4 is attached to the supporting member 61 by the spacer 7.
Supported via a likewise Te state odor fixing plate 62 via a spacer 7 on the upper surface of the web 4 it is is placed, from the head side to the large diameter of the through hole 63a of the transmural throughbore 63, six The head of the square headed bolt 64a and the small diameter washer 64b
The bolt assembly 64 is inserted until the bolt assembly 64 protrudes.

The bolt assembly 64 is moved from the side of the through hole 63a to the side of the long hole 63b while slidingly contacting the surface opposite to the plate 62. Next, as shown in FIG.
When the nut 65 is rotated in the tightening direction while the spanner s is hung on 4d to prevent the hexagonal head bolt 64a from rotating, the mesh 4 is pressed by the support member 61 and the fixing plate 62 via the spacers 7, 7. It is fixed.

上に対して多大な効果がある。As described above, according to the vibrating sieve net mounting apparatus according to the present invention, the bolts constituting the bolt assembly are passed through the support member and the fixing plate from the head side from the top side of the net. The inner diameter of the hole is inserted from the through hole having a large dimension, and then the inserted bolt assembly is moved by pressing the bolt assembly toward the elongated hole having a width smaller than the inner dimension of the through hole connected to the through hole. By tightening the nut so that it does not rotate with the rotation prevention part at the end on the head side, the inner part in the width direction of the mesh can be fixed, and on the contrary, the nut is loosened and the bolt assembly is The fixing plate can be removed by moving it from the side to the through hole side and removing it, so that one worker is not required by two workers on the upper and lower sides of the net as in the conventional example. Network can be safely and easily attached and detached There is a great effect on the improvement of the safety and work efficiency in.
