Description

The present invention relates to a sliding carriage. More specifically, the present invention relates to a slide-type carriage for storing various scraps and other materials to be transported to a predetermined location in a steelworks, for example, and discharging them.

For example, in a steelworks with a wide installation area, so-called scrap such as shavings, shavings, and analyzed samples generated at each blast furnace and analysis center is transported to a disposal bag installed at a predetermined location, and stored there. need to be discharged.

Conventionally, as a means for conveying such scrap, a rotary conveying cart has been disclosed (see, for example, Patent Document 1).
This carriage has a structure in which a bucket body having a substantially inverted trapezoidal shape on the side surface is provided on a carriage that is manually pushed by a worker, and the bucket body is tilted so as to be rotatable about a fulcrum pin.

Since this carriage has a structure in which the bucket body is rotated and tilted, it has the advantage of being easier to discharge the transported objects in the bucket body than the one in which the bucket body is fixed.

Further, as means for conveying scrap, a carrier 60 shown in FIG. 8 is disclosed.
This transport cart 60 is also constructed by rotatably providing a bucket body 61 on the cart 60, and is pushed by a worker's hand for transport. The bottom wall of the bucket is provided with a side triangular extending portion 61b that is linearly extended forward. (between the bag) to ensure that it drains into the waste bag without spillage.

Since the bucket body 60 is rotatable in this carriage as well, there is an advantage that it is easy to discharge the conveyed object. In addition, since the extended portion 61b is provided to reduce the distance from the waste bag, there is an advantage that the scrap can be more reliably discharged into the waste bag.

Utility Model Registration No. 3141223

However, the carriage described in Patent Document 1 and the carriage having the extension shown in FIG. 8 still tend to form a gap between the waste bag and the waste bag. There is a problem that it is difficult to discharge.

In the carriage shown in FIG. 8, it is conceivable to further extend the extension part, but since the bucket body is large and heavy, it is not practical as a carriage that is manually pushed by a worker to convey.
In addition, since the carriage is provided with an extension, gaps and steps are likely to be formed between the carriage and the main body. If such gaps or steps are formed, scraps will be clogged or accumulated there, so there is a problem that it is difficult to completely discharge the scraps in the bucket body into the disposal bag. There is also the danger of cutting your hands when disposing of the scrap left in the bucket.

The slide-type trolley 1 according to the present embodiment is used in the premises of a steelworks, and scraps (conveyed objects) such as cutting chips, cutting chips, or analyzed samples generated in a plurality of blast furnaces, analysis centers, testing laboratories, etc. It is a slide-type trolley that conveys and discharges to a disposal bag B, which is a predetermined location, and includes a trolley body 10 , a base 20 , a bucket mechanism 30 , and an elevating mechanism 50 . In particular, the bucket mechanism 30 is provided directly above the base 20 and includes a carrier 31 , a movable plate 32 and a bucket body 33 .

The carriage body 10 includes a push handle 13 at the rear end of a loading platform 11 and a plurality of (usually four) wheels 12 on the lower surface of the loading platform 11 .
The push handle 13 has a height that can be easily grasped and pushed by a worker, and the wheels 12 are made of rubber tires to suppress running noise. The type of the wheel 12 is not limited, and for example, it can be made of steel or resin, which are excellent in durability. It can also run on rails.

The base 20 is in the form of a flat plate provided directly above the carriage body 10 via an elevating mechanism 50. At the front end of the base 20, a first stopper S1 for restricting the forward movement limit position of the movable plate 32 is erected. , a second stopper S2 for restricting the backward movement limit position of the movable plate 32 is erected at the rear end.
Further, a third stopper S3 is provided between the base 20 and the movable plate 32 to restrict movement of the movable plate 32 in the front-rear direction. The third stopper S3 is inserted through an upper hole 32c formed in the movable plate 32 and a lower hole 20a formed in the base 20. As shown in FIG.

The conveying body 31 of the bucket mechanism 30 is elongated, is fixed to the upper surface of the base 20 along the front-rear direction, and is configured by rotatably providing a plurality of rotating rollers 31a at equal intervals.
Three conveying bodies 31 of this embodiment are arranged in the horizontal direction at equal intervals, but this number is not limited. It should be noted that the carrier 31 can also be fixed to a flat mounting board (not shown) and fixed to the upper surface of the base 20 via this mounting board.

The movable plate 32 of the bucket mechanism 30 has a flat plate shape and is arranged on the roller member 31a of the carrier 31 so as to be movable in the front-rear direction. The front end of the movable plate 32 serves as a forward motion restricting portion that contacts the first stopper S1, and the rear end serves as a backward motion restricting portion that contacts the second stopper S2.

A bucket body 33 of the bucket mechanism 30 is arranged directly above the movable plate 32 and accommodates an object to be conveyed inside, and has a substantially box shape with an opening 33a opened and closed by an opening/closing lid 34 on the front surface. On the upper surface of the bottom wall of the bucket body 33, a flat plate-like rubber material 37 for cushioning is arranged in a replaceable manner over almost the entire surface.

A fitting member (not shown) for inserting the opening/closing lid 34 in a vertically slidable manner is provided in the opening 33a. The configuration of the fitting member is not limited, and for example, it may be configured to have a concave groove into which the entire or a part of the left and right ends of the opening/closing lid 34 are inserted. Note that the open/close lid 34 is not limited to a vertical slide type, and may be, for example, a horizontal slide type or a rotating type.

The bucket body 33 is attached to the movable plate 32 via the tilting member 40 .
The tilting member 40 has a rotating shaft 41 extending in the left-right direction, and the rotating shaft 41 is fixed to the lower surface of the bottom wall of the bucket body 33 directly or indirectly via a connecting member 36 (see FIG. 3). The rotary shaft 41 can be supported by bearings 42 . As a result, the bucket body 33 can freely tilt back and forth about the rotary shaft 41 with respect to the movable plate 32 . The rotating shaft 41 is arranged so as to extend in the left-right direction and perpendicular to the front-rear center of the lower surface of the bottom wall of the bucket body 33 .

A fourth stopper S<b>4 is provided between the movable plate 32 and the bucket body 33 to prevent tilting of the bucket body 33 with respect to the movable plate 32 . The fourth stopper S4 has a through hole 32b formed in two standing projections 32a erected from both left and right ends of the movable plate 32, and a hole formed in a hanging projection 35 hanging from the lower surface of the bottom wall of the bucket body 33. It is inserted through the portion 35a. The shape, number, and installation location of the standing projections 32a and the hanging projections 35 are not limited.

The elevating mechanism 50 is provided between the loading platform 11 of the carriage body 10 and the base 20, and has the function of raising and lowering the base 20. The elevating mechanism 50 includes two pairs of link structures 51 provided on the left and right sides and, for example, a foot-operated hydraulic mechanism. A jack device (not shown) is provided, and the base 20 is moved up and down by operating the jack device.

The sliding carriage 1 according to the present embodiment having the above configuration can be used as follows. This will be explained with reference to FIGS. 4 to 6. FIG.
First, for example, scrap generated in a blast furnace or the like is stored in the bucket main body 33 and conveyed to the disposal bag B by being manually pushed by a worker.
In this conveying state, as shown in FIGS. 4 and 5, the opening 33a of the bucket body 33 is closed by the opening/closing lid 34, and the link structure 51 of the lifting mechanism 50 is lowered. By lowering the link structure 51, the position of the bucket body 33 can be lowered, so scrap can be easily thrown in, and the center of gravity of the slide type carriage 1 can be lowered. Therefore, it can be transported in a stable posture.

Also, in this transport state, the third stopper S3 is inserted through the upper hole 32c of the movable plate 32 and the lower hole 20a of the base 20 from above to prevent unnecessary movement of the movable plate 32 in the front-rear direction. Furthermore, the fourth stopper S4 is inserted through the through hole 32b of the standing plate 31a and the hole 35a of the hanging plate 35 to prevent the bucket body 33 from tilting.
In addition, by arranging a rubber material 37 for buffering on the upper surface of the bottom wall of the bucket body 33, the sound generated when scrap is thrown into the bucket body 33 and when the slide type carriage 1 is conveyed can be effectively suppressed. Suppress. Also, the bottom wall of the bucket body 33 is prevented from being damaged by scrap.

When the slide type carriage 1 is conveyed to the disposal bag B, the third stopper S3 is removed and the movable plate 32 is moved forward until its front end abuts against the first stopper S1.
The forward movement of the movable plate 32 can be performed extremely smoothly by the rotating roller 31b. In addition, since the forward movement limit position of the movable plate 32 is set by the first stopper S1, it is possible to prevent the movable plate 32 from falling from the carrier 31 into the waste bag B.
By moving the movable plate 32 forward in this manner, the bucket body 33 can be brought closer to the waste bag B, so that the scrap can be easily discharged into the waste bag B without spilling it around.

Prior to the above operation, the hydraulic jack device is operated to raise the link structure 51 . As a result, the bucket body 33 can be positioned above the disposal bag B, so that the scrap can be discharged into the disposal bag B more easily.

After moving the movable plate 32 forward, as shown in FIG. 6, the fourth stopper S4 is removed, and the bucket body 33 is manually pushed to tilt forward. Since this tilting is performed by rotating the rotating shaft 41 of the tilting member 40, it can be performed with a light force. Further, since the rotating shaft 41 is arranged at the front-rear center of the lower surface of the bottom wall of the bucket body 33, unlike the case where the rotation shaft 41 is arranged at the front of the front-rear center, the force is extremely small. can be easily done with

The scrap stored in the bucket body 33 is discharged to the disposal bag B by tilting the bucket body 33 .
At this time, since the movable plate 32 is advanced to the forward movement limit position and the link structure 51 of the lifting mechanism 50 is raised, the opening 33a of the bucket body 33 is positioned forward of the rear end of the waste bag B. can be positioned above it. Therefore, the scrap of the bucket body 33 can be reliably discharged into the disposal bag B without being scattered around.
Further, since the bucket body 33 is substantially box-shaped, compared with an inverted trapezoidal bucket, there is little risk of spillage during transportation even if the conveyed object has a shape such as a cylinder or a sphere that rolls easily.

After discharging the scrap, the bucket body 33 is tilted in the opposite direction to return to the lower state, the fourth stopper S4 is inserted through the through hole 32b and the hole 35, and the opening/closing lid 34 is attached to the opening 33a and slid. Transport the trolley 1 to its original location and prepare for the next use.

In the above embodiment, the forward movement limit position is set by bringing the first stopper S1 into contact with the front end of the movable plate 32 . In such a configuration, the rotary shaft 41 is inevitably located behind the first stopper S1, and the forward movement limit position of the movable plate 32 is limited to some extent.
In order to remove such limitation, as shown in FIG. 7, a configuration in which the rotating shaft 41 is arranged forward of the first stopper S1 can be employed. In this case, as the bucket body 33 moves forward, the weight moves in the opposite direction to maintain balance, thereby preventing the bucket body 33 from falling.
This configuration can be ensured by providing the first stopper S1 behind the front end of the base 20 and providing a contact projection 32b on the side surface of the movable plate 32 to contact the first stopper S1. As a result, the forward movement limit position of the movable plate 32 (bucket body 33) can be set further forward, so that the scrap of the bucket body 33 can be discharged into the disposal bag B more reliably.

The slide type trolley 1 of the above embodiment is intended to be used for scrap at steelworks, but it is not limited to this, for example, it can be used in any situation such as transportation and discharge of earth and sand at a construction site. can be used.

In addition, the trolley body 10 of the above-described embodiment includes a push handle 13 and is pushed by a worker's hand for use. .
Further, the conveying body 31 is not limited to the roller member 31a (rotating roller 31b), and may be, for example, a spherical body, or a chain or belt provided in a circular or reciprocating manner. Also, the tilting member 40 can be composed of the rotary shaft 41 and the bearing 42, but is not limited to this, and any mechanism for tilting the bucket body 33 can be employed.
