Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a discharge port in a shipping facility using a belt conveyor or the like.

[Prior Art] Conventionally, when shipping lumps or granules such as coal or ore, a shipping device 10 using a belt conveyor or the like is used as shown in FIG.

This loading device 10 includes a head chute section 1 which is the tip of a main body section 11 that houses a belt conveyor.
A discharge port 13 is provided below the discharge port 13, and as shown in FIGS. 5 and 6, a telescopic chute 18 is often provided below the discharge port 13.
The loading operation is carried out by lowering the hatch 19 so that the tip of the hatch 8 is inserted into the hold.

[Problems to be solved by the invention] As mentioned above, when inserting a telescopic chute into a ship's hold, the loading equipment is fixed on land, but the ship is subject to damage, even if only slightly, due to wind and waves and tidal currents. Since it is a device that oscillates or moves, the hatch part may come into contact with the telescopic chute, which may deform the telescopic chute and make it impossible to extend or contract. Operators had to be careful not to let the telescopic chute come into contact with the hatch of the ship, as this would have an adverse effect.

[Means for Solving the Problems] The present invention is a belt conveyor for shipping equipment, in which a telescopic chute provided at the discharge port is attached below the discharge port in the head chute portion of the shipping device via an elastic body, and thereby The chute is horizontally swingable with respect to the main body of the loading device.

[Function] Since the present invention attaches the telescopic chute to the head chute of the shipping device main body via an elastic body, the telescopic chute contacts the ship's hatch and receives pressure from the side. This prevents deformation of the telescopic chute and twisting of the main body of the loading device due to swinging of the telescopic chute.

[Example] As an example of the present invention, a shipping belt conveyor will be described.

As shown in FIG. 2, this shipping device is provided with a belt conveyor 15 in the main body 11 of the loading device, and a discharge port 1 is located just below the end of the belt conveyor 15.
3, the tip of the main body 11 is a head chute 12, and a telescopic chute 18 is provided below the discharge port 13.
As shown in FIG. 1, a holding plate 27 is provided in the vicinity of the upper end of the head part 8, and a holding plate 27 is provided which projects left and right. 18 to the main body 11
It is attached to the head shoot part 12 which is the tip of the head.

That is, a holding plate 27 that projects horizontally from near the upper end of the telescopic chute 18 is provided with a through hole through which the guide rod 24 passes, and a mounting bracket 26 to which the lower end of the spring 25 is welded and fixed is secured by bolting or the like. The upper end of the guide rod 24 passing through the hole and the upper end of the spring 25 are fixed to the flange 2.
The flange 23 is attached with a pin 22 to a fixture 21 provided on the lower surface of the head chute 12 of the shipping device 10, so that the flange 23, guide rod 24, spring 25, etc. can be moved forward and backward. The gap between the fixture 21 and the holding plate 27 can be expanded and contracted while being able to swing in the direction.

The through hole of the holding plate 27 is formed into an elliptical shape whose major axis is in the left-right direction, and is larger than the outer diameter of the guide rod 24.
A lock nut 28 is attached near the lower end of 4,
To prevent the holding plate 27 from accidentally coming off from the guide rod 24. Furthermore, a limit switch is provided at the position of the lock nut 28, and the holding plate 27 is
In some cases, it may be possible to detect a case where a large drop has occurred.

As described above, in the shipping device 10 according to the present invention, the holding plate 27 is provided at the upper end of the telescopic chute 18, and the holding plate 27 supports the telescopic chute below the head chute portion 12, which is the tip of the main body, via the spring 25. 18 is suspended, so when the hatch 19 or the like comes into contact with the telescopic chute 18 from the left and right directions, and an external force is applied to the telescopic chute 18 from the right direction, for example, the spring 25 on the right side stretches and the spring on the left side 25 is retracted, the telescopic chute 18 swings to the left, and the helical springs 25 provided on the left and right allow the telescopic chute 18 to be displaced relative to the head chute portion 12 of the loading device, and furthermore to the main body portion 11 of the loading device, thereby preventing external force. This can prevent deformation of the telescopic chute 18 and twisting of the main body 11.

Furthermore, when the hatch 19 or the like comes into contact with the telescopic chute 18 from the front and rear directions, the collar 23 to which the guide rod 24 and spring 25 are fixed is attached to the fixing device 21 by a pin 22, so it moves back and forth around the pin 22. The telescopic chute 18 can swing in the direction, and when an external force is applied to the telescopic chute 18 from the hatch 19, the telescopic chute 18 can swing and release the external force.If no external force is applied to the telescopic chute 18, the telescopic chute 18 The telescopic chute 18 suspended by its own weight is maintained in the vertical direction.

If a limit switch is provided near the lower end of the guide rod 24, the limit switch stops the operation of the belt conveyor 15, and also causes a buzzer to sound and a warning light such as a lamp to turn on the telescopic chute 18. When the telescopic chute 18 receives a large external force in the left-right direction and the shaking of the telescopic chute 18 increases, the operator can be notified of danger.

Further, in the above embodiment, one spring 25 is provided on each of the left and right sides of the telescopic chute 18 to make one set, but as shown in FIG. In some cases, a set of four helical springs 25 are provided to hang the telescopic chute 18, and three springs 25 are attached to the telescopic chute 1 at 120° intervals.
It may also be placed around 8.

As a still further embodiment, as shown in FIG. Fix the guide rod 24 upward from the
4 into the center of the helical spring 25, and place the spring 25 on the horizontal part 32 of the hanging bracket 31. Furthermore, insert the guide rod 24 into the through hole of the holding plate 27, and place the spring 25 on the spring 25. A holding plate 27 may also be placed.

In this case, the limit switch 35 can be installed not only at the lock nut 28 position of the guide rod 24, but also at an appropriate position inside the hanging fitting 31.

In this embodiment, the spring 25 is placed on the horizontal part 32 of the hanging fitting 31, and the telescopic chute 18 is attached by placing the holding plate 27 on top of the spring 25, so maintenance such as spring replacement is not necessary. It has the advantage of being easy to disassemble.

In addition, when using the hanging fitting 31, the helical spring 25
Alternatively, a thick rubber plate may be used as the elastic body.

[Effects of the invention] In this invention, the telescopic chute is attached to the head chute of the loading equipment main body so that it can swing, so when the lower end of the telescopic chute receives a horizontal external force from the hatch in the hold, the telescopic chute does not swing. Therefore, it is possible to prevent the deformation of the telescopic chute and the occurrence of twisting and distortion of the loading device, allowing safe loading work.
