Description

[Detailed Description of the Invention] [Industrial field of application] The present invention aligns a moving machine around a coke oven, such as a coal charging vehicle, an extruder, or a guide wheel, with a coke oven carbonizing chamber or a coal charging hole. It relates to the device.

[Conventional technology]

Coking furnaces include coal charging vehicles, extruders, and guide vehicles as mobile machines for work.

For example, a coal charging vehicle travels on a rail arranged at the top of a coke oven furnace and charges coal through a coal charging hole provided on each coke oven carbonizing chamber.

At the time of this coal charging, the coal charging vehicle had to be accurately aligned with the coal charging hole.

This positioning accuracy requires a high accuracy of about ± 5 mm, and a skilled driver on a coal charging vehicle made fine adjustments by inching operation.

However, in recent years, labor saving has also been promoted in this coke oven, and the operation of the coal charging vehicle is being automated.

An apparatus for automatically performing this fine adjustment is disclosed in, for example, Japanese Patent Laid-Open No. 59
There is a proposed fixed position stop device in Japanese Patent Laid-Open No. 109583, which will be described with reference to FIGS. 5 (a), (b) and (c).

This is supported by a guide rail 2 hung on a lower body frame 1 of the coal charging vehicle and is movably movable in the traveling direction of the coal charging vehicle 1 (directions of arrows A and B) by both rod cylinders 5. 3, a lever 7 rotatably supporting an intermediate portion is provided on both sides of the carriage 3, and a clamp cylinder 6 is provided between the upper ends of the lever 7 and the lever 7.
The device is configured by providing a clamp portion 13 for clamping the rail 12 at the lower end of the.

When the coal charging vehicle travels on the rail 12 and stops at a predetermined position, first, the cylinder 6 is extended and the lever 7 is rotated to clamp the side surface of the rail 12 by the clamp portion 13 to trolley the truck 3.
To fix. Thereafter, both rod cylinders 5 are operated to move the coal charging vehicle in the direction of arrow A or B to finely adjust the body frame 1 of the coal charging vehicle.

[Problems to be solved by the device]

However, Japanese Laid-Open Patent Publication No. 59-109583 discloses that the rail 12
As a clamping mechanism for clamping the
The lever 12 is rotatably provided, and the clamp cylinder 6 is provided at the upper end of the lever 7. The cylinder 6 is operated to rotate the lower end of the lever 7 to clamp the rail 12 laterally. However, there is a problem in that the clamp mechanism has a complicated structure.

An object of the present invention is to provide a fixed position stopping device having a simple structure.

[Means for Solving the Problems]

The present invention solves the above problems by providing a structure in which a contact member such as a rail or a block is pressed from above, and means 1 thereof is a mobile machine around a coke oven traveling on a rail. A guide rail provided on the lower body frame of the moving machine in parallel with the rail, a trolley fitted to the guided rail so that a guided portion can travel, and provided between the trolley and the lower body frame of the moving machine. And an inching mechanism for inching the moving machine in parallel with the rail, and a bogie position fixing mechanism that is provided in the lower part of the bogie so as to be vertically movable and presses / separates a contact member below the bogie.

As the abutting member, an iron plate laid on the rail installation surface in the moving range of the mobile machine or an iron block provided on the rail installation surface at the stop position of the mobile machine may be used, but in terms of equipment cost, 2 is preferable for running the mobile machine.

Further, it is preferable that the liquid or gas cylinder of the means 3 is used as a driving unit for the inching mechanism and the carriage position fixing mechanism because it is structurally simple.

Further, when the rails for traveling the mobile machine are used as the contact members, it is preferable that both rails are fixed by the carriage position fixing mechanism and then inching by the inching mechanism.

[Action]

 The operation of the present invention will be described with reference to FIGS.

The present inventors have made two rails 12 for traveling of the coal charging vehicle 11 as the abutting member, and various examinations have been made so that the position of the coal charging vehicle 11 can be finely adjusted without adversely affecting the rails 12. I went.

It is generally known that, due to its fixed structure, the rail 12 is very weak against lateral and downward acting forces and extremely strong against upward acting forces.

It was found that there is no adverse effect on the rail 12 that fixes the rail 12 by applying the action from above and the pressing force (30 to 40 tons) required for inching can be obtained. .

Therefore, it suffices to simply hang the bogie position fixing mechanism 22 on the bogie 19 and attach the bogie position fixing mechanism 22 to the bogie 19, which is structurally very simple and compact.

However, if the amount of movement of the rail 12 in the lateral direction (the direction perpendicular to the longitudinal direction) is large, if the tip of the lot 22a of the carriage position fixing mechanism 22 deviates from the head position of the rail 12, it becomes impossible to press-contact.
The present inventors examined the amount of lateral movement and the pressure contact member 22b at the tip of the cylinder lot 22a.

As a result of this examination, the lateral movement of the rail 12 having a lateral width of the head of about 100 mm is about 10 mm on the left and right, and the width of the pressure contact member 22b is about the same as the lateral width of the head of the rail 12. Then, since the press contact member 22b is not disengaged from the center of the rail 12, it was confirmed that the rail 12 hardly receives the lateral action when the bogie position fixing mechanism 22 presses the rail 12.

After fixing the carriage 19 to the rail 12 by the carriage position fixing mechanism 22 in this manner, the inching mechanisms 23a and 23b are operated,
The mobile machine is finely adjusted to a predetermined position.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS.

In the figure, 10a and 10b are the lower surface of the charging vehicle 11 and the traveling wheels 13
A guide rail having a U-shaped cross section provided on the body frame 14 between a and 13b, 19 is a trolley, and the guide rails 10a and 10b
Guide wheels 16a and 16b as guided parts that are fitted to the
And the axles 15a, 1 rotatably provided on the guide wheels 16a, 16b.
5b and plates 19 located above both sides of the rail 12 provided on the furnace top 20 of the coke oven and suspended and fixed to the axles 15a and 15b.
It is composed of a and 19b and a beam 19c connecting the plates 19a and 19b.

With this configuration, the carriage 19 can run in parallel to the rail 12 provided on the top 20 of the coke oven (the running direction of the charging vehicle 11).

Reference numeral 22 is a carriage position fixing mechanism provided on the beam 19c, and the carriage position fixing mechanism 22 is a hydraulic cylinder 22c as a drive unit.
And the rod 22a of the hydraulic cylinder 22c and the rod 22a
The pressure contact member 22b has a length of 100 mm and is firmly fixed to the tip of the pressure contact member 22b.

23a and 23b are inching hydraulic cylinders as an inching mechanism, and the inching hydraulic cylinders 23a and 23b
Connect the plates 19a and 19b of the carriage 19 to the rod tip of b,
The plates 19a and 19b can be inched parallel to the rail 12.

Next, this operation will be described.

First, the charging vehicle 11 is electrically controlled to stop near the charging hole (not shown) for charging coal.

Next, the hydraulic cylinder 22c is operated to extend the rod 22a, and the pressure contact member 22b starts to pressure contact with the rail 12.

Then, when the rail 12 is pressed and fixed at a predetermined pressure by the pressure contact member 22b, the operation of the hydraulic cylinder 22c is stopped.

At this time, for example, even if the rail 12 deviates slightly in the lateral direction and the center axis of the tip of the rod 22a of the hydraulic cylinder 22c deviates from the rail 12, the pressure contact member 22b does not deviate from the center of the rail 12, so the rail 12 moves in the lateral direction. It hardly receives the action force of.

Next, in order to accurately position the charging vehicle 11 at a predetermined position, the inching cylinders 23a and 23b are operated to extend or contract the rod R.

As a result, the trolley 19 is moved by the hydraulic cylinder 22c to the rail 1
Since the position is fixed at 2, the charging vehicle 11 starts moving in parallel with the rail 12.

Then, when the charging vehicle 11 is accurately aligned with the predetermined position, the operation of the inching hydraulic cylinders 23a, 23b is stopped.

Then, coal is loaded from the charging vehicle 11 into a coal charging hole (not shown).
Through a carbonization chamber (not shown) of the coke oven.

When the charging of coal is completed, the hydraulic cylinder 22c is contracted to separate the pressure contact member 22b from the rail 12 and release the pressure contact state.

Further, the inching hydraulic cylinders 23a and 23b also operate to return the carriage 19 to a predetermined position.

In this way, the charging vehicle 11 travels to a coal tower (not shown) to receive coal.

In addition, although the present embodiment has described only the coal charging vehicle, the present invention is not limited to this, and may be provided in an extruder, a guide vehicle, or the like.

Further, although only one rail 12 is described in the present embodiment, the fixed position stop device described above is also provided on the other rail (not shown), and both rails operate in synchronization.

Further, in the present embodiment, the case where the rail 12 is used as the contact member has been described, but an iron plate or a block is provided in the intermediate portion between the left and right rails 12, and this is fixed by pressing it from above by the carriage position fixing mechanism. You may do it.

[Effect of device]

The fixed position stop device of the present invention described above has a simple structure and does not exert a lateral action on the rail even if the contact member is a rail, so that the rail is not adversely affected. Further, since the structure is simple as described above, it is possible to reduce the height of the fixed position stop device of the present invention, and it is possible to mount it at any position such as between the wheels of the moving machine. There is almost no limitation on the mounting position, which is advantageous in terms of design.
