DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of parallel belt conveyors, and more particularly to a common girder.

[0002]

2. Description of the Related Art FIG. 4 shows a front sectional view of a plurality of conventional belt conveyors arranged side by side, and FIG. 5 shows a side view thereof. In FIG. 4, 31 is one conveyor belt, 3
2 is the other conveyor belt, 33 is one girder framed in a quadrilateral supporting the belt 31, 34 is another similar girder supporting the belt 32, 35 is a sidewalk receiving material, 36 Is a sidewalk, 37 is a cable tray, 38 is a handrail, 39 is a belt cover, 40 is a side cover, 41
Is a powder fall prevention plate, 42 is a saddle, and 43 is a support. In FIG. 5, reference numeral 44 denotes a carrier roller, and 45 denotes a return belt.

That is, the conveyor belts 31 and 32 are separately supported by respective girders 33 and 34, and the sidewalk 36 and the cable tray 37 are also supported. The belts 31 and 32 are surrounded by a belt cover 39, a side cover 40, and a powder fall prevention plate 41.

[0004]

However, in the conventional plural-parallel belt conveyor device shown in FIGS. 4 and 5, each of the conveyor belts 31, 32 is supported by a separate girder 33, 34. So the girder 3
The loads are distributed to the members 3 and 34, but the loads on the sidewalks 36 and the cable trays 37 are applied as eccentric loads. Therefore, in order to suppress the displacement, it is necessary to insert a cross-sectional brace or enlarge the members. There is also a dust-prevention plate 41 provided under the return belt 45, but it is difficult to manufacture because of the cross-sectional brace and the like. In the inspection and replacement of the girder, there is a problem that the side slope members and the vertical members of the girder 33, 34 are close to each other and hinder the work.

[0005] The present invention is to solve the above problems. That is, the present invention can reduce the eccentric load on the girder, improve the rigidity,
It is another object of the present invention to provide a multiple-parallel belt conveyor device capable of facilitating maintenance of the belt conveyor.

[0006]

Means for Solving the Problems The present invention to achieve the above object, comprises a single common girder which supports the plurality aligned conveyor belt (1,2) (13), said common gas
The frame has a frame formed in a right-angled quadrilateral shape by connecting members (14a, 14) on the upper and lower surfaces and a vertical member on the side surface (15) .
A rectangular parallelepiped connected in plural in the longitudinal direction of the belt conveyor
Each of the belt conveyors has a common structure.
A plurality of stringers (3,
5) A multi-parallel belt conveyor device which is supported from both sides according to (5) .

[0007]

According to the present invention, the connecting member and the side vertical member are used.
Connect multiple frameworks formed in a rectangular shape
Produce a common girder with a body shape and place it on top of the common girder
Provide a plurality of stringers that extend to
Therefore, to support the belt conveyor from both sides,
The bearer belt load is supported by multiple stringers,
Each stringer is supported by one common girder
Because, it becomes less stable structures load cantilever, it becomes significantly less eccentric load. In addition, it is possible to prevent the eccentric load from being applied by placing the cable tray and the pipes equally on the upper surface of the joint member of the girder.

[0008]

FIG. 1 shows a front sectional view of an embodiment of the present invention.
2 is an enlarged side view of FIG. 1, and FIG. 3 is an enlarged right half of FIG. In FIG. 1, 1 is one conveyor belt,
Reference numeral 2 denotes another conveyor belt, reference numeral 3 denotes a stringer supporting a carrier roller and return roller of the one conveyor belt 1 described later, reference numeral 5 denotes a stringer supporting similar rollers of the other conveyor belt 2, and reference numeral 7 denotes a sidewalk receiving material. , 8 is a sidewalk, 9 is a handrail, 10 is a belt cover, 11 is a side cover, and 12 is a powder fall prevention plate.

Reference numeral 13 denotes a common girder, which is formed into a right-angled quadrilateral by a lower-side transverse member 14, an upper-side transverse member 14a, and a side-perpendicular member 15, as can be seen in FIG.
The framework that was developed is shown in Fig. 2 as a belt conveyor.
A From a rectangular parallelepiped structure connected in the longitudinal direction
Has become. 16 is a cable tray of an accessory mounted on the upper surface of the lower joint 14 of the common girder 13, 17 is the same piping, 18 is a column supporting the common girder 13, and S is its span. is there.

Further, in FIG. 2, reference numeral 19 denotes a diagonal member for reinforcing the side vertical member 15 of the common girder 13, and in FIG. 3, reference numeral 20 denotes a carrier roller, and reference numeral 21 denotes a return roller.

That is, the load on one conveyor belt 1
Is supported by stringers 3 from both sides, and the load of the other conveyor belt 2 is supported by stringers 5 from both sides . The stringers 3 and 5 are located above the common girder.
It is growing to. In addition, on the upper surface of sidewalk receiving material 7, sidewalk 8,
In addition to the handrail 9 and the powder fall prevention plate 12, stringers 3 and 5 for the belts 1 and 2 are provided. Further, the common girder 13 supports the entire load applied to the sidewalk receiving material 7 and is supported by the columns 18.

In the belt conveyor device of a plurality of parallel type constructed as shown in FIGS. 1 to 3, all the upper loads are supported by one common girder 13, so that the cantilever load is small and stable. In addition, since the accessory parts such as the cable tray 16 and the piping 17 are arranged almost equally on the left and right sides of the joint member 14 on the lower surface of one common girder 13, the common girder 13 Does not act as an eccentric load.

At the time of maintenance, the belt cover 1
0. Since the side cover 11 is removed, the inspection and replacement work of the carrier roller 20, the return roller 21, and the like, and the work of cleaning the powder fallen on the powder fall prevention plate 12 are of a stringer type, there are few obstacles. So you can easily do it.

[0014]

As described above, according to the present invention,
The belt conveyor includes one common girder supporting a plurality of belt conveyors, and each of the belt conveyors has a stringer for supporting a carrier roller and a return roller. Because it consists of a structure framed in a right-angled quadrilateral shape consisting of a joining material and a side vertical material, the load of each conveyor belt is supported by each stringer, and it is supported by one common girder, A stable structure with a small cantilever load, a significantly small eccentric load, and a common girder below the dust-prevention plate allow a simple structure with few obstacles upward.

Therefore, when cleaning the powder falling under the return belt and when checking and replacing the roller, there are few obstacles, so that it can be easily formed. Because it can be taken
The number of struts and foundations can be reduced.
