Abstract

PROBLEM TO BE SOLVED: To provide a wire-pull conveyor with a large loading amount at low cost by constituting a conveyor body out of a movable member, forming a string type body connected to both its ends through a plurality of lifting metal fittings, and equipping plural pairs of rollers which clamp the string type body at a head part, a tail part, and a middle part from the vertical direction. SOLUTION: The conveyor belt 2 of a conveyor body 1 is constituted of movable members such as wire net, cloth and synthetic rubber. One end of lifting hardware 3 is bolted to both the ends of the conveyor belt 2. String type bodies, or wire ropes 4, are fitted to the other ends of a plurality of the lifting hardware 3 to hold them. When an article (W) to be carried is loaded onto the conveyor belt 2, the conveyor belt 2 curves downward. Longitudinal tension occurs at the lifting hardware 3, and the wire ropes 4 try to come off from an annular groove 34a in a wire receiving roller 34, however tire rollers 35 which clamp the wire ropes 4 together with the roller 34 suppress it and prevent it from being lifted and coming off.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire pull conveyor structure.

[0002]

2. Description of the Related Art For the transportation of loose materials such as crushed stones, gravel, sand, earth and sand, and cement by a conventional belt conveyor, it is necessary to install a highly rigid frame over the entire transportation line. Therefore, it can only be applied to expensive, large-scale, long-term construction work that can be expected to be sufficiently depreciated.

Further, since the conveyor belt is supported by carrier rollers, the loading amount is limited.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wire pull conveyor structure which has a large loading amount and is inexpensive.

[0005]

According to the present invention, there is provided a head portion for driving a conveyor body, a tail portion for inverting the conveyor body, and a conveyor body for traveling between the head portion and the tail portion. In the conveyor, the conveyor main body is made of a flexible member, and is provided with a string-like body connected to a plurality of hanging metal fittings at both edges, and the head-like part, the tail part, and the intermediate part sandwich the string-like body from above and below. Is provided with a plurality of sets of rollers.

[0006]

In the structure of the wire pull conveyor configured as described above, when articles to be conveyed are stacked on the belt main body, the belt main body composed of the flexible member bends downward. Therefore, although tension is generated in the hanging metal fitting in the longitudinal direction, the string-shaped body is sandwiched and supported by a plurality of sets of rollers.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2, the wire pull conveyor comprises a head portion 10, a tail portion 20, and a conveyor main body 1 which runs between the head portion 10 and the tail portion 20. When the distance between 20 is large, the intermediate support column 3 that supports the conveyor body 1 in the middle
0 and 30 are provided, and when loading is performed in the middle, an intermediate support column 30A for loading is provided.

In FIGS. 3 and 4, the conveyor belt 2 of the conveyor body 1 is made of a flexible member such as wire mesh, cloth, and rigid rubber. One end of the hanging metal fitting 3 is bolted to both end edges of the conveyor belt 2 at intervals D (for example, 1 m). A string-shaped body, that is, a wire rope 4 is attached to the other ends of the plurality of hanging fittings 3 so as to be held.

In FIGS. 5 to 7, the head portion 10 is shown.
The base 11 is provided with a plurality of beams 11a for preventing slippage that are orthogonal to the conveyor main body 1, and a frame-shaped frame 12 is erected on the base 11.
A drive drum 14 driven by a drive motor 13 is provided above one end of the frame 12, and the conveyor belt 2
Are wound around the drive drum 14 and inverted. A plurality of carriers for holding the way rope 4 in cooperation with the frame 12 and gradually expanding the outward path portion 2a of the conveyor belt 2 having a concave shape downward by the weight of the article W to be flattened and transferred to the drive drum 14. Roller 15 and line pulley 1
Six sets are provided. And, to the wire ropes 4 and 4 of the return path portion 2b of the conveyor belt 2, the pressing roller 17 for effectively transmitting the driving force to the wire ropes 4 and 4,
17 is pressed from below. Incidentally, reference numeral 18 in FIG.
Moves the drive drum 14 back and forth to move the wire ropes 4, 4
It is a wire rope tension correction device for keeping the tension acting on the wire constant, and the tension is constantly measured and corrected by a load cell (not shown). Reference numeral 19 in FIG. 7 is a carrier roller.

In FIGS. 8 and 9, the tail portion 20 is provided with a support shoe 21 which can be freely moved and fixed, and a frame-shaped frame 22 is erected on the support shoe 21. This frame 22 has a conveyor belt 2
Is provided with a tail drum 23 that rotates in accordance with the above, and a carrier roller 15 and a line pulley 16 similar to the head unit 10 are provided. Incidentally, reference numeral 24 in the drawing
Is a pressing roller that supports the return path portion 2b of the conveyor belt 2. Then, the tail portion 20 pulls the bracket 22a of the frame 22 in the direction of the arrow with a not-shown bulltozer or the like to apply tension to the wire ropes 4, 4. Reference numeral 25 in the drawing is a loading unit.

10 to 12, the intermediate support column 3
A pair of support shoes 31 that can be freely moved and fixed is provided at 0, and a frame-shaped frame 32 is erected on the support shoes 31, 31. On the upper surface of the frame 32, two pairs of guide devices 33 that support the forward path portion 2a of the conveyor belt 2 are provided, and at the lower part, a carrier roller 36 that supports the return path portion 2b of the conveyor belt 2 is provided. .

Referring also to FIGS. 3 and 4, the guide device 33 includes two wire receiving rollers 34 for supporting the wire rope 4, and the wire rope 4 in cooperation with the rollers 34.
And a tire roller 35 for preventing the wire from floating. And both rollers 34, 34
And 35 are urged outward by means not shown,
According to the bending of the forward path portion 2a of the conveyor belt 2 due to the conveyed article W, it can be moved by the distance L.

In FIG. 13, the intermediate support column 3 for loading
0A includes a receiving hopper 37 and a plurality of receiving hoppers 37 (3 in the illustrated example).
Carrier rollers 19), and the other structure is similar to that of the intermediate support column 30.

Next, when the articles W are loaded on the conveyor belt 2 which will be described below, the conveyor belt 2 bends downward as shown in FIG. Therefore, the tension in the longitudinal direction is generated in the hanging fitting 3, and the wire rope 4 tends to come off from the annular groove 34 a of the wire receiving roller 34.
It is restrained by the tire roller 35 that holds the wire rope 4 together with the roller 34, and is prevented from rising and coming off.

[0016]

Since the present invention is configured as described above, it has the following effects.

(1) It is possible to provide a frame at a low cost, which does not require a frame having high rigidity over the entire line like a belt conveyor. (2) The loading amount can be increased as compared with the conventional case. (3) Since the conveyed product is wrapped, it is hard to roll down even if the conveyor is inclined. (4) Also, it can be installed and operated according to the unevenness of the installation ground. (5) Compared with the conventional belt conveyor, the number of carrier rollers is small, the vibration to the conveyed product is small, and there is no fear of liquefaction. (6) When passing the conveyor over valley topography, in the conventional truss conveyor, it was necessary to provide stanchions at appropriate intervals in the valley, but with this conveyor, a large span can be taken and it is simple. It can be transported by the device.
