Abstract

PURPOSE:To enable cargo work without causing dust to be generated by stretching a conveyor belt with selvage supports and cross supports in a column, all over its heights, which is erected on a portal and on which a boom is rotatably supported at the top end, and providing a cover belt adjacent to this conveyor belt. CONSTITUTION:A boom 5 is rotatably supported by the top end of a column 23 which is erected on a traveling portal 11, and an excavating device 3 is installed on the bottom end part of a frame 4 which is suspended from the end of the boom 5. A conveyor belt 18 is provided in the frame 4, boom 5, and column 23, being stretched across a bend pulley 20, a driving pulley 24, a bend roller 19, and a tail pulley 17. In this conveyor belt 18, selvage supports are provided on its both sides, while a number of cross supports are provided on the conveying surface, at a certain interval. A cover belt 10 is provided adjacent to the discharge side of the conveyor belt 18 in the column 23, to prevent loose objects in a pocket, formed between the selvage and cross supports, from falling.

Description

[Detailed description of the invention] The present invention relates to a cargo unloader.

6) It is loaded onto the top and conveyed by the conveyor bell (06) from its discharge end via the chute (o7) to the column (
The conveyor belt (012) is fed into a hopper (o9) provided in 08), passes through a shoe (010) connected to this hopper (o9), and then passes through a cross-feeding conveyor bell (012) suspended in a portal (011). ) and is transported by this transverse conveyor belt (012) through the chute (013) at the end of the above-ground conveyor belt (012).
14) After being transferred to the top, it is conveyed to the desired location.

Therefore, the bulk goods (o2) are transported from the conveyor belt (o6) stretched inside the boom (o5) (07),
In the process of being transshipped via the hopper (09), shoe) (010) to the transverse conveyor bell) (012), the bulk items (02) are transferred to the hopper (nQ), shoe) (07), hopper (nQ), tnrkrmrFmds l m+, -),
t a&Irn rAQS lff1, h', mAbrasion causes bulk material (02) to be destroyed or powdered. In particular, when the bulk material (02) is coke or the like, this destruction and powdering greatly reduces its commercial value.

The present invention was proposed in order to deal with the above-mentioned problems, and its gist is that the cargo is loaded by an excavator attached to the tip of a boom that is pivotally supported at the upper end of a column standing in the portal. In the cargo handling conveyor in which bulk goods are conveyed by a conveyor belt running in the zoom, passing through the column and onto a transverse conveyor suspended in the portal, the total height of the conveyor is A conveyor belt with an ear crosspiece and a horizontal crosspiece is stretched across the belt, and the conveyor belt with the ear crosspiece and horizontal crosspiece is covered and cooperates with the conveyor belt to receive the loose materials conveyed by the conveyor belt and transfer them to the horizontal conveyor. The cargo handling unloader is characterized by being provided with a covering member that limits a pocket to be transported.

Since the present invention has the above-mentioned configuration, it is possible to reduce the destruction and pulverization of loose materials, and also to prevent the generation of noise and dust due to collisions of such objects.

Hereinafter, the first embodiment of the present invention shown in FIGS. 2 to 9 will be explained in detail. In Figure 2, (1) is the quay, (2) is the ship, (3) is the drilling rig, (4) is the frame, (5 is the boom, (6 is the balance weight, (7) is

The boom (5) and the column (c) extend over their entire length and travel in the direction of the white arrow. Cover belt OO1
is stretched between the fixed pulley 0υ and the take-up pulley (c). As shown in Fig. 4, the conveyor bell (18) and the cover bell (GO) are pinched by the rollers (TO) that abut against their back surfaces and transfer, and the cover bell (10) ) Q8) ear bars (1

The conveyor belt (10) is supported by a fixed pulley 0υ and a take-up pulley (c) as shown in Figures 8 and 9. Fixed boo IJ (2
1) is supported by bearings (4υ) at both ends,
A bearing box (43 (44)) containing four bearings (0υ) is mounted on a bracket (4!9 (46)) fixed to the inner cylinder (C).

Both ends of the take-up pulley (29) are equipped with bearings (47), (
48), and the bearings (47) and (48) are built into the shaft fertilizer (50), which is slidably guided by a guide 511 and pulled by six take-up screws (cover bell) (10). ) is given the required tension.

As a result, the bulk storage stored in the hold 641 was scraped off by the excavator (3) and transferred to the conveyor belt (18).
It is loaded onto the top and transported inside the zoom (5), and when it is turned downward by the bend pulley (A), it is covered by the cover belt (10) and enclosed in the pocket 0]), and the column (C) The conveyor belt gradually descends at the running speed of the conveyor belt 8) and is transferred onto the transverse conveyor αω.

Thus, unlike the conventional system shown in FIG. Never.

A second embodiment of the invention is shown in FIGS. 10-14. Bulk materials in the hold 6 are excavated and lifted by an excavation device 6e such as a packet elevator, and transferred via a shoe (757) onto a flat bell (5110) suspended within the boom (5). The flat bell 58) is stretched between the tail spool and the rotatably driven head pulley 160) and is caused to travel in the direction of the white arrow. As is clear from FIG. 11, within the column (c), a conveyor belt H1) is stretched over its entire height between a drive pulley 621 and a take-up pulley (631), and runs in the direction of the white arrow. As is clear from FIG. 12, an ear crosspiece (61α) and a horizontal crosspiece (6]j) are fixed to the surface of the conveyor bell H1). As is clear from FIG. 13, both ends of the drive pulley 162+ are supported by bearings (-), and one end of the drive pulley 162+ is connected to a motor port with a reduction gear via a coupling field, and bearings (641, t651) Built-in bearing box (68
) t691 and the motor mouth are fixed on the platen Hυ, (72) fixed to the casing σ[.

Both ends of the take-up pulley are fitted with bearings σ (71,
t76J is guided by a guide σD and is pulled by a take-up screw (781 (79)) to apply tension to the conveyor belt H.

The casing (70) is disposed within the column (23), covers the second side of the conveyor (ru) ([11)] on its descending side, and cooperates with the ear bar (61α) and the horizontal bar (6]J). Pocket) fllO) is limited. A knee NT7J covering the discharge end of the bell) 681 is connected to the upper end of the casing (70). The rest of the structure is similar to the first embodiment shown in FIGS. 2 to 9, and corresponding members are given the same reference numerals.

Then, the bulk material 65 that was conveyed on the flat belt 51D inside the boom (5) is fed from the discharge end of the flat belt marked 6 through the shoe 721 onto the conveyor belt (6υ). , as the conveyor bell H1l runs, the blur bounded by this and the casing (101) 118
01 and gradually descends, and the transverse conveyor is transferred onto Yaω.

In this way, the separate storage space is divided into columns (c) like the conventional one.
This prevents the bulk material from falling through the container and colliding with the hopper, chute, etc., thereby preventing the bulk material from being destroyed or pulverized.
