Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated joining of a low-wear resin plate of a conveyor belt and a carrier guide made of a hollow cushioning material for carrying powder and granular materials such as earth and sand, quarry and coal. is there.

Conventionally, in a conveyor belt carrier,
To prevent the connecting portion of the belt between the carrier roller transport directions of the belt conveyor from bending downward due to the weight of the conveyed object when the conveyed object is fed from the hopper or the like onto the belt conveyor and conveyed. A composite of a rubber plate and a resin plate with high abrasion resistance, such as high molecular weight polyethylene, is placed between the belt carrier rollers in the conveying direction, and the belt is slid on the composite. It is known to prevent bending (Japanese Utility Model Laid-Open No. 60-137711), and further, a support body in which an upper surface of a shock-absorbing rubber material is coated with an ultra-high molecular weight polyethylene plate along the lower side of the belt conveyor. Is installed,
A technique to prevent the scattering of the conveyed objects from both sides by placing skirt plates on both sides on the belt in the conveying direction (Actual Development Showa 6
No. 2-183609) is also disclosed. In this way, by arranging the carrier guides arranged in the belt connecting portion between the carrier rollers of the conveyor belt and the skirt plates on both side portions of the belt, the impact caused by dropping the conveyed object is mitigated, Although it is possible to prevent falling and scattering of objects, there is little bending of the belt when transporting things such as cement powder and wheat flour that do not have weight, and the gap between the skirt plate and the skirt plate on the belt conveyor is correspondingly reduced. Although there is little scattering of the powder of the carrier, the weight per unit area is large in the case of heavy loads such as earth and sand, ore, and coal, and the conveyor belt also flexes correspondingly, which is a carrier to prevent this. There is a limit to the number of rollers that can be arranged, and it has been a serious problem to prevent the loss of conveyed articles by preventing loosening of the belt.

Even if an excellent low-abrasion resin such as ultra-high molecular weight polyethylene is used as a carrier guide having excellent impact resistance and abrasion resistance, the heavier the load is, the lower the weight of the conveyor belt becomes. Due to the high friction, the wear loss of the carrier guide is high and the frequent replacement is required. In this way, before the damage of the belt conveyor itself due to wear occurs, it is very important economically to detect the wear degree of the carrier guide, accurately catch the wear limit, and replace the carrier guide in a timely manner. is there. However, since a general-purpose wear-resistant carrier guide is usually formed by adhering and integrating a low-wear resin plate and a hollow cushioning body with an adhesive, one of the low-wear resin plate Even if it wears, it is uneconomical because the entire carrier guide in which the low-wear resin and the hollow cushioning body are integrally bonded must be replaced. In order to improve this, a means for replacing only the low-wear resin plate when the low-wear resin of the carrier guide is worn is also disclosed (Japanese Utility Model Laid-Open No. 5-82920). Since a complicated fitting shape is required to prevent friction between the plate and the hollow cushioning body, a complicated mold is required to manufacture the above two, and furthermore, a fitting for integration is required. There was an inconvenience.

[0004]

As described above, the carrier guide including the low-wear resin plate and the hollow cushioning member is useful as a member for preventing the belt from bending and for mitigating the drop impact of the conveyed object. However, when the low-wear resin plate wears due to the severe friction with the conveyor belt, there is a problem in the troublesomeness and economy of replacing the low-wear resin plate, and it is easy and economical to replace only the low-wear resin plate. There was a need for an effective means.

[0005]

Means for Solving the Problems The present inventors have found that the low abrasion resin plate of a carrier guide is worn out, and when it is necessary to replace it, it is simple and economical to exchange only the low abrasion resin plate. As a result of earnestly investigating means, the present invention was finally conceived. In the present invention, the low-wear resin plate and the hollow cushioning body in the carrier guide are joined and integrated with the low-wear resin bolt, and the wear of the low-wear resin plate of the carrier guide is confirmed at the time when the need for replacement is confirmed. It is possible to remove the abradable resin bolt, replace only the worn low abradable resin plate, and attach a new low abradable resin plate with a bolt of the same material.

The structure of the present invention basically has the following structure. (1) carrier guide trough-shaped cross-section of the plateau and / or both sides of the outer high inclined conveyor belt consisting of a low wear resistant resin plate and a hollow cushion disposed on the sidewalls view part of, the low friction
The abradable resin plate and the hollow shock absorber are fixed to each other by a fixing plate or a washer.
A carrier guide for a conveyor belt, characterized in that it is joined and integrated with a bolt made of low-wear resin via a carrier. (2) The carrier guide is fixed on the lower surface side of the conveyor belt at a predetermined interval in the conveying direction, that is, on a stand frame arranged between the carrier rollers of the conveyor belt. The carrier guide for the conveyor belt of Item 1. (3) A carrier guide for a conveyor belt, wherein the low-wear resin is ultra-high molecular weight polyethylene. (4) The width of the upper surface of the low-wear resin plate is equal to the width of the upper surface of one hollow buffer member, or a plurality of hollow buffer members arranged in the horizontal region of the trough-shaped cross section and the side wall regions at both outer heights. A carrier guide for a conveyor belt that is equal to one unit of continuous body or a mixture of both. The low-wear resin plate integrally joined with the hollow cushioning body of the present invention is a rectangular long plate body,
Low wear resins such as ultra high molecular weight polyethylene and wear resistant polyamide are used. The hollow buffer body is not particularly limited in material as long as it is in the range of natural rubber and synthetic rubber. The hollow cushioning member supports the upper low-wear resin plate and gives a cushioning effect. The hollow cushioning member is not limited in shape and size, but is preferably a rectangular parallelepiped having a hollow cross section and a hollow interior. Further, several rectangular parallelepipeds are arranged in parallel and used so as to support a conveyor belt having a trough shape under the weight of a conveyed object from below. The material of the low abrasion resin plate includes ultra high molecular weight polyethylene and abrasion resistant polyamide, but ultra high molecular weight polyethylene having a molecular weight of about 4,000,000 to 5,000,000 is particularly suitable for the present invention because of its excellent abrasion resistance. is there. The width of the low-wear resin plate is made equal to the width of one hollow cushioning body, or each hollow cushioning body is divided and arranged in the horizontal region of the trough-shaped cross section and the side walls with high outside inclination on both sides. 1 unit, eg 3 in the horizontal area,
When two buffers are arranged on both side walls, the total width is three for the horizontal region and the total width is two for each side wall. Furthermore, the degree of wear,
For example, it is ideal in terms of material cost to subdivide a place that requires frequent replacement as much as possible, but it takes time to replace it, so it is appropriate to combine both appropriately.

[0007]

The carrier guide of the conveyor belt of the present invention is
Since the low-wear resin plate and the hollow cushioning body are integrated by joining and using bolts, when the low-wear resin plate wears, the bolt is removed and only the worn low-wear resin plate is removed. And replace with a new low abrasion resin plate with bolts. By using the bolts made of the same material as the low-wear resin plate, the bolts are worn to the same extent as the low-wear resin plate, and the bolts do not remain protruding and damage the conveyor belt.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The carrier guide of the conveyor belt of the present invention will be specifically described based on the embodiments shown in the drawings, but the present invention is not limited thereto. Figure 1
Shows the state of falling and carrying of a lumped carrier such as earth and sand, ore, coal, etc. in the guide shoe area in the conventional carrier. In FIG. 1, a belt conveyor 4 equipped with a fall prevention skirt plate 3 for preventing the article 2 from falling from the lateral side in the conveying direction.
However, when the carrier roller 5 transfers between the transfer rollers, it is bent due to the weight and impact of the conveyed product, and a gap is formed between the skirt plate 3 and the lower portion of the skirt plate 3 on the belt conveyor. Shows. FIG. 2 shows a cross section (that is, a cross section in the carrying direction) at an angle perpendicular to the carrying direction in the conventional conveyor belt device, and the carrying is performed between the carrier rollers 5 arranged in the carrying direction of the belt. 1 shows a state in which an object 2 is conveyed. A carrier guide 6 composed of a low abrasion resin plate 7 and a hollow cushioning body 8 is provided on the lower side of a conveyor belt that becomes a trough shape due to the weight of the object, and both sides on the belt. A skirt plate 3 which is substantially vertical is provided in the section. The low-wear resin plate and the hollow cushioning body of the present invention are integrally joined as shown in FIGS. 3 and 4, and the bolt 9 is made of the same material as the low-wear resin plate 7. Integral joining with the bolt 9 taps (female screw groove) at the fixing point of the low-wear resin plate 7.
A hole 11 is drilled and aligned with the tap hole 11 drilled in the hollow cushioning member 8 at a required position, so that a fixing plate 12 and a washer 13 are provided.
Through the bolt 9 using the bolt. The hollow buffer body 8 is
Since it is rectangular and the inside is a rectangular parallelepiped with a cavity 14, it can be easily joined and integrated by bolting with a fastener such as a wrench. FIG. 5 shows a fixing mode of the stand frame 10 of the hollow cushioning body 8. The hollow cushioning body 8 is arranged on the lower surface side of the conveyor belt 4 at predetermined intervals.
It is fixed on the frame 10 by a suitable bolt 15. In the present invention, when the low-wear resin plate 7 is worn, the bolt 9 is removed when replacing only the low-wear resin plate 7,
Only the worn low-wear resin plate is removed and a new low-wear resin plate is attached with bolts.

[0009]

When the low wear resin plate of the carrier guide is worn, only the low wear resin plate can be replaced by a simple means, which is economical. Further, since the bolt for joining and integrating is made of the same material as the low-wear resin plate, it is not worn evenly with the low-wear resin plate, and the bolt does not remain protruding to damage the conveyor belt. Since the hollow buffer body has a cavity, it has a large buffering effect.
