Description

[Detailed description of the invention] The present invention relates to a bucket transport device for coke dry extinguishing equipment, and in particular eliminates the guide rail in the range that interferes with the coke guide car, simplifying the equipment, and improving safety during bucket transport. The present invention also relates to a bucket transport device for coke dry extinguishing equipment, which improves the durability of the device.

Generally, coke dry extinguishing equipment is equipped with a bucket transport device for conveying red-hot coke discharged from a coke oven to the top charging port of a coke dry extinguishing tower. As shown in Fig. 1, this bucket transport device consists of a bucket transport car b installed in front of a coke oven discharge port a so as to be able to run parallel to the discharge port a, and a bucket c placed on the transport car b. In order to guide the red hot coke discharged from the discharge port a into the bucket c while preventing the dust generated from the discharge port a, a conveyor b is provided above the transport vehicle b so as to be freely movable along this running direction. It mainly consists of a coke guide car d and a hoist f for hoisting the bucket c on the transport car b and transporting it to the charging port e of the fire tower. In order to ensure smooth and reliable transfer of the bucket c on the hoisting transfer path g for hoisting and lowering the bucket c, guide wheels h are provided on both sides of the bucket c, while on the hoisting transfer path g. A guide rail i for guiding the guide wheel h is provided along this.

By the way, in the case of such a conventional bucket transport device, since the guide rail i was provided over the entire length of the elevator transfer path g, in order to avoid interference with the coke guide car d that runs intersecting with the guide rail i. ,
It was necessary to make the lower end j of the guide rail i shiftable. However, the bucket c to be lifted weighs nearly 60 tons, including coke.
In addition, a large load is applied to the guide rail i due to the unevenness of the coke in the bucket, and a large load is applied to the guide rail i.
The upper transfer section is accompanied by a large impact. For this reason, the conventional bucket transport device has become extremely unreasonable and uneconomical because the lower end j of the guide rail i, which is subject to such impact, is made to have a structure that can be shifted while being strengthened. Furthermore, in order to prevent the coke guide car d from colliding with the lower end j of the guide rail, it was necessary to constantly monitor this and control the shifting of the lower end j.

The present invention has been devised in view of the problems of the conventional apparatus as described above and to effectively solve these problems. The purpose of the present invention is to provide a bucket transport device for cox dry fire extinguishing equipment that can simplify equipment and reduce coasting, as well as simplify operation control and improve safety and durability. It's about doing.

A preferred embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

In FIGS. 2 to 4, 1 is a bucket for conveying red-hot coke discharged from the discharge port 2 of the coke oven to the top charging port 3 of the fire extinguishing tower;
On both sides of this bucket 1, guide wheels 4 are installed on the upper and lower sides.
A hanging pin part 6 is provided for removably hooking a hook 5 for lifting the bucket 1.

A rail 8 is laid on the floor 7 in front of the discharge port 2 of the coke oven in parallel to the direction in which the discharge ports 2 are lined up, and on this rail 8 a bucket transport vehicle 9 carrying the bucket 1 runs runs. freely supported.
On this transport vehicle 9 is a bucket 1 placed on it.
An engagement rail 10 having a predetermined length for engaging the guide wheel 4 is provided facing vertically upward in order to stabilize the movement of the guide wheel 4. This engagement rail 10 consists of a pair of rail members 10 that face each other at a predetermined distance so as to sandwich the guide wheel 4 from both sides.
a and 10b, and the upper end thereof is formed in a widening shape or a flap shape so that the guide wheel 4 can be easily inserted thereinto.

In a portion located in front of the discharge port 2 of the coke oven and above the bucket transport vehicle 9, red heat discharged from the discharge port 2 is disposed astride between the discharge port 2 and the bucket transport vehicle 9. A coke guide car 11 for guiding coke into the bucket 1 while preventing dust generated therefrom is provided so as to be movable along the traveling direction of the transport car 9. In FIG. 3, reference numeral 12 denotes a rail arranged to guide the coke guide car 11.

A lifting path 13 for lifting and lowering the bucket cart 1 is connected to a suitable location on the rail 8 of the transport vehicle 9, and an upper end of this lifting path 13 is used for hoisting and lowering the bucket cart 1. A hoisting machine 15 with running wheels 14 is provided for conveying the fuel to the charging port 3 of the fire tower. A frame 16 constructed to partition the lifting and lowering transfer path 13
At the upper end, there is a rail 1 for guiding the hoisting machine 15 from the top of the elevator transfer path 13 to the top of the charging port 3 of the fire tower.
7 are arranged.

The hoisting machine 15 is equipped with a rope 18 having a hook 5 at the tip for hoisting the bucket 1, and has a predetermined length at the bottom for engaging the guide wheels 4 to stabilize the hoisted bucket 1. An engagement rail 19 is provided so as to face vertically downward and hang down. Similar to the engagement rail 10 on the carrier 9, this engagement rail 19 is a pair of rail members 19.
A and 19b are configured to face each other.

A guide rail 20 for guiding the guide wheels 4 of the bucket 1 along the lifting and lowering transfer path 13, excluding the portion through which the coke guide car 11 passes, is provided. Like the engagement rails 10 and 19, this guide rail 20 is composed of a pair of rail members 20a and 20b facing each other so as to sandwich the guide wheel 4 from both sides. The upper end of the guide rail 20 is set with a clearance that does not interfere with the lower end of the engagement rail 19 of the hoist 15, and the lower end of the guide rail 20 is provided with a buffer for the guide wheel 4. An introduction rail 21 with a damper is provided for introducing the material while the material is being introduced. This introduction rail 21 consists of a pair of rail pieces 21
a, 21b, these rail pieces 21a, 2
The base end of 1b is a rail member 20 constituting a guide rail 20 so that its free end can move freely to open and close.
A and 20b are respectively pivotally supported at the lower end portions via pins 22. And the rail pieces 21a, 21
A damper 23 is provided between the free end portion of b and the frame 16 to maintain the free end portion facing vertically downward. This damper 23 has a coil spring 23b built into a cylinder 23a, and is configured so that the coil spring 23b absorbs and relieves the impact force applied in the direction of expanding the rail pieces 21a, 21b. Note that the damper is not limited to this, and any damper may be used as long as it can absorb impact force and restore its original state. Further, the lower portions of the rail pieces 21a, 21b are formed in a flared shape so that the guide wheels 4 can be easily introduced.

On the other hand, a bottom support member 24 for supporting the bottom of the carrier vehicle 9 is provided at the lower end of the elevator transfer path 13. This bottom support member 24 is used when the bucket is lifted and the bucket guide wheels 4 are connected to the engagement rail 1.
This is to prevent the transport vehicle 9 from falling due to the impact when it comes off the zero position, and in the illustrated example, the support base 24a is fixed on the floor surface 7 on the outside of the rail 8.
and a support jack 24b that is extendably provided at the bottom of the transport vehicle 9 facing the support base 24a. By extending the support jack 24b and seating it on the support base 24a, the transport vehicle 9 is supported. I'm starting to do that.

The bottom support member 24 is not limited to this. For example, the support base 24a may be placed close to the bottom of the support base 24a with a small gap provided therein so as not to support the traveling of the transport vehicle 9.

Next, the operation of the embodiment will be described.

When transporting the bucket 1 on the transport vehicle 9, the hook 5 of the rope 18 fed out from the hoist 15 is removed from the hanging pin part 6 of the bucket 1, and the bucket 1 is placed in the exhaust of the coke oven. It is carried to the front of the outlet 2 and receives the red hot coke through a coke guide car 11. Once the red-hot coke has been deposited in the bucket 1, the carrier vehicle 9 is moved below the elevator transfer path 13, the support jack 24b is extended, and the support stand 24 is moved.
At the same time, the hook 5 of the rope 18 let out from the hoist 15 is hooked onto the hanging pin part 6 of the bucket bag 1. Then, by winding up the rope 18, the bucket 1 rises from the transport vehicle 9 and is transported upward along the vertical transfer path 13. In this case, if the red hot coke is thrown into the bucket 1 unevenly, the bucket 1 will tilt due to the uneven load when the bucket 1 is floated, and the force will be transferred from the guide wheel 4 through the engagement rail 10. This will act on the transport vehicle 9. However, since the bottom of the transport vehicle 9 is supported by the support jack 24b and the support base 24a, even if it receives force from the bucket cart 1, it will not fall.

The bucket 1 is further rolled up and reaches the introduction rail 21, and the guide wheels 4 are regulated while colliding with the introduction rail 21, thereby restoring its posture. Since the impact force at this time is absorbed by the damper 23, the durability of the guide wheel 4 and the introduction rail 21 is improved. The guide wheel 4 is guided onto the guide rail 20 by the introduction rail 21, and after rising on the guide rail 20 for a while, it is transferred from the guide rail 20 onto the engagement rail 19 of the hoist 15.

Once the bucket 1 is held under the hoisting machine 15, the hoisting machine 15 is moved to above the charging port 3 of the fire tower, and the red hot coke in the bucket 1 is dropped and charged into the fire tower from the charging port 3, and the following steps are carried out. The empty bucket 1 is returned onto the transport vehicle 9 by the reverse process to that described above, and the same operation is performed. In addition, since the empty bucket 1 is well balanced, it descends smoothly along the lifting/lowering transfer path 13.

As described above, since the introduction rail 21 with a damper is provided at the lower end of the guide rail 20, the bucket 1 can be smoothly moved upwards even though the guide rail in the part that interferes with the coke guide car 11 is omitted. It can be done. Further, since the guide rail in the portion that interferes with the coke guide car 21 is omitted, there is no need to monitor collisions between the guide car and the guide rail, which simplifies the equipment and reduces equipment costs.

In summary, the present invention exhibits the following excellent effects.

(1) A guide wheel is provided on the side of the bucket, and a guide rail is provided to guide the guide wheel along the lift transfer path, excluding the portion where the coke guide car passes, and a guide rail is provided at the lower end of the guide rail. Since an introduction rail with a damper is provided to buffer the wheels and introduce them onto the guide rail, the bucket can be smoothly moved upwards even though the guide rail that interferes with the coke guide car is omitted. .

(2) Furthermore, the introduction rail with a damper can absorb and reduce the impact force when the guide wheel is introduced, and the durability of the guide wheel etc. can be improved.

(3) Since the guide rail in the part that interferes with the coke guide car is omitted, it is possible to simplify the equipment and reduce costs, and it is possible to control the shifting of the guide rail to avoid interference with the coke guide car. There is no need to do this, and operation control can be simplified.

(4) Furthermore, a support member for supporting the bottom of the bucket transport vehicle is provided at the lower end of the elevator transfer path, so red hot coke may be thrown unevenly into the bucket, causing the bucket to tilt during lifting. Even if an attempt is made to overturn the transport vehicle, it is possible to reliably prevent the transport vehicle from overturning, and the safety during transport in a bucket can be improved as much as possible.
