Description

[Detailed description of the device]

[0001]

[Industrial applications]

 A conveyor belt for transporting gravel, crushed stone, coal, coke, ore, etc., has a hopper for loading the gravel, etc. on the conveyor belt and a portion of the gravel, etc. The present invention relates to the guide device for the conveyor belt, which is provided with a guide device for absorbing the shock caused by dropping.

[0002]

[Prior art]

 As a guide device for the above conveyor belt, the one described in Japanese Utility Model Publication No. 31454/1993 is known. As shown by reference numeral 5 in FIG. 4, this known guide device has a carrier guide 3 formed by laminating a covering material 2 made of ultrahigh molecular weight polyethylene on the upper surface of a long rectangular member 1 made of shock absorbing rubber. A plurality of U-shaped pillows 4 are fixed to a book or a plurality of U-shaped pillows 4 at predetermined intervals in an intersecting manner. This fixing is performed in a T-shape in the longitudinal direction provided on the lower surface of the square 1. Insert the head of a T-shaped bolt 16 (see FIGS. 1 and 3) into the groove 1a, pass the shaft through the bolt hole formed in the U-shaped pillow 4, and tighten the nut on the protruding end. . A support shaft 4b is provided on the left and right side plates 4a of the U-shaped pillow 4 so as to project outward.

FIG. 5 shows a usage state of the guide device 5 shown in FIG. 4, 6 is a chute for charging the crushed stone A, and 7 is an endless conveyor belt. A base 8 is horizontally provided below the chute 6, and at the left and right end portions of the base 8, tall outer columns 9A are arranged in two rows on the left and right sides, and short inner columns 9B are arranged on the inner sides in two rows on the left and right sides. The guide device 5 is vertically installed between the outer strut 9A and the inner strut 9B on the left side, between the inner strut 9B and 9B in the two central rows, and between the inner strut 9B and the outer strut 9A on the right side. It is supported by inserting the support shaft 4b into the vertical grooves 9c provided at the upper ends of the columns 9A and 9B from above, and is accompanied by the square material 1 of the carrier guide 3 parallel to the conveyor belt 7 when the crushed stone A is thrown. The covering material 2 buffers the impact and forms the surface layer of the carrier guide 3. The conveyor belt 7 can smoothly slide.

[0004]

[Problems to be solved by the device]

 In the guide device 5 including the carrier guide 3 and the U-shaped pillow material 4, the U-shaped pillow material 4 is formed by a groove-shaped material that is long in the width direction of the conveyor belt 7, and side plates 4a are provided at both ends thereof. Since the height of the upper end of 4a protrudes to a height substantially equal to the upper surface of the carrier guide 3 to form a U-shape, after removing the worn carrier guide 3, the outer strut 9A and the inner strut 9A are removed. In order to attach a new carrier guide 3 to the U-shaped pillow material 4 supported between 9B, insert the head of the T-shaped bolt into the T-shaped groove 1a (see FIG. 4) on the lower surface of this carrier guide 3 beforehand. Then, lift the conveyor belt 7 to form a large space between the conveyor belt 7 and the U-shaped pillow 4, insert the carrier guide 3 into this space from the side, and then downward from the carrier guide 3. It is necessary to insert the lower end of the T-bolt protruding into the bolt hole of the U-shaped pillow material 4, so that the conveyor belt 7 must be lifted over a relatively long distance, and the above replacement work requires a long time. It took a lot of work.

Further, instead of inserting the head of the T-shaped bolt into the T-shaped groove 1 a of the carrier guide 3, the lower end of the T-shaped bolt is inserted into the bolt hole of the U-shaped pillow material 4, and the head is inserted into the U-shaped structure. The carrier guide 3 is slid in the length direction along the upper surface of the U-shaped pillow 4 while floating from the surface of the U-shaped pillow 4, and the head of the T-shaped bolt is fitted into the T-shaped groove 1a to carry the carrier. The yarn guide 3 can be mounted, but in this case, since the long carrier guide 3 must be slid parallel to the conveyor belt 7 while floating a large number of T-shaped bolts below the conveyor belt 7, the carrier guide 3 is also required. Replacing the guide 3 took a long time and required a lot of labor.

This invention makes it almost unnecessary to lift the conveyor belt when exchanging the carrier guide, thereby facilitating the work, thereby reducing the labor and the work time.

[0007]

[Means for Solving the Problems]

 A conveyor belt guide device according to the present invention is a carrier guide in which a T-shaped groove is provided in the lower surface length direction of a long rectangular member made of shock-absorbing rubber, and a coating material made of ultra-high molecular weight polyethylene is laminated on the upper surface. And a pillow material which is fixed to intersect with a plurality of lower surfaces of the carrier guide, the upper surface of the pillow material is formed flat, and support shafts are outwardly projected on both end surfaces of the pillow material. At the center of the material, there is provided a flat upper surface fitting fitting projecting parallel to the carrier guide along the lower surface of the carrier guide, and the fitting fitting is provided with a notch groove extending from one edge thereof to the central part. The shaft portion of the T-shaped bolt, the head of which is inserted into the T-shaped groove on the lower surface of the rectangular member, is inserted into the cutout groove of the connecting fitting, and the nut is tightened at the downward protruding end of the shaft portion.

[0008]

[Action]

 As in the conventional case, when the above pillow material is supported between the left and right columns provided under the conveyor belt under the chute by inserting the support shaft at the end into the vertical groove at the top of the column, Place the above-mentioned carrier guide with the head of the T-bolt inserted into the T-groove on the lower surface of the material, at one end of the above-mentioned pillow material so that the T-bolt may come off from the pillow material to the side of the connection fitting, and then above-mentioned carrier guide. When moved horizontally along the upper surface of the pillow material, the shaft portion of the T-bolt enters the notch groove of the connection fitting. In this case, since the carrier guide is moved laterally along the upper surface of the pillow material, it is not necessary to lift the conveyor belt high as in the conventional case. Then, after adjusting the position of the carrier guide, the nut is fastened to the tip of the T-shaped bolt to fix the carrier guide to the pillow.
