Description

[Detailed Description of the Invention] "Industrial application field" The present invention relates to a furnace lid attaching / detaching device for a coke oven coal charging vehicle.

"Prior Art" In the lid removing device for a conventional charging vehicle, as shown in Fig. 6, S-shaped guides a, a are provided at the lower part of the machine frame 12, and the tip of a reciprocating frame b that moves up and down along the same rail. Lifting parallel link c
Since the support ring d of the lifting magnet for adsorbing the lid is provided via the support ring d, the support ring d moves up and down in an inclined state, so that the lid removing work height t ′ is high, and the reciprocating frame b moves horizontally and vertically. Since there is an S-shaped movement in the direction, the installation space and the space for raising and lowering the charging hood are large, and the weight and the number of parts are large.

"Problems to be solved by the invention" This plan reduces the lid work height to lower the machine height, reduces the installation space of the reciprocating frame and the lifting space of the charging hood, and reduces the weight and the number of parts. The purpose is to obtain a simple furnace lid attachment and detachment.

"Means for solving the problem" This proposal provides a guide guide at the bottom of the machine frame of a coal charging vehicle, supports the reciprocating frame on the guide, and attaches a lifting magnet for furnace lid adsorption to the tip of the frame. In a lid removing device for a loading vehicle in which a support ring is provided via a vertically movable parallel link, the guide guide is formed by a horizontal linear rail, and the drive cylinder of the moving frame is pivotally supported by the guide. The upper end of the connecting rod is pivotally supported on the tip of the cylinder, the lower end of the connecting rod is pivotally supported on the end of the moving frame, the connecting rod and the parallel link are connected by a connecting tool, and the horizontal straight line is connected. An arcuate rail centered on the lower end pivotal support portion of the connecting rod is connected to the tip end of the linear rail, a guide roller provided on the connecting rod is engaged with the linear rail or the arcuate rail, and The moving frame moves back and forth on a straight line along the above linear rail. A coke oven that is supported so as to move is constituted by a furnace lid attaching / detaching device at the coal charging port.

[Operation] Therefore, when the drive cylinder 4 is extended, the moving frame 3 advances to the position shown by the solid line in FIG. 1, and further, the guide rod 9 of the connecting rod 5 rotates along the arcuate rail 8 about the pivotal support. The same FIG. 1 moves from the virtual line position to the solid line position. Therefore, the parallel links 6 and 6 ′ are lowered from the phantom line position (inclined position) in FIG. 1 to the solid line position (horizontal position) to attract the lifting magnet 14 supported by the support ring 15 to the furnace lid 13. After that (after the magnet 14 and the furnace lid 13 are horizontally reciprocally rotated by the reciprocating parallel rods 21, 21), the drive cylinder 4 is contracted, and the connecting rod 5, the guide roller 9, the parallel link 6, 6 ', the support ring 15, the lifting magnet 14, and the furnace lid 13 move from the solid line position in FIG.
Enter the above linear rail 2 from the moving frame 3 in that state.
Is retracted to the position shown by the solid line in FIG. 2 and stopped, and the furnace lid 13 is removed. When the furnace lid 13 is attached to the charging port 27, the operation opposite to the above removing operation is performed.

[Example] A coke oven 10 has a pair of rails 11 and 11 laid on the furnace top, and a guide guide 1 and a guide 1 are provided under a machine frame 12 of a coal charging vehicle that runs on the rails 11 and 11. A movable frame 3 that reciprocates along the line is supported. A supporting ring 15 of a lifting magnet 14 for adsorption of the furnace lid 13 is provided at the tip of the moving frame 3 via parallel links 6 and 6'to form a lid removing device. The above guide 1 Formed by upper and lower horizontal linear rails 2 and 2 formed of I-shaped or I-shaped rails, and the rails 2 and 2 are provided at the rear of the guide 1.
The driving cylinder 4 of the moving frame 3 is pivotally supported by a horizontal pin 16 orthogonal to the. The moving frame 3 includes a front wheel 17 that contacts the upper surface of the lower linear rail 2 and a rear wheel 1 that contacts the lower surface.
It is supported by 8 so as to reciprocate horizontally along the rail 2. A horizontal pin 19 is provided at the tip of the moving frame 3.
The lower end of the connecting rod 5 is pivotally supported by, and the upper end of the connecting rod 5 is pivotally supported by the horizontal pin 20 at the tip of the cylinder 4. A guide roller 9 is provided on the connecting rod 5, and the roller 9 is in contact with the lower surface of the upper linear rail 2 and can reciprocate in the horizontal direction along the upper rail 2 while maintaining the position shown by the solid line in FIG. The tip end of the upper linear rail 2 forms an arcuate rail 8, which is an upwardly bulging arc centered on the lower end horizontal pin 19 of the connecting rod 5, so that the cylinder 4
The guide roller 9 is rotated along the lower surface of the arcuate rail 8 from the phantom line position in FIG. 1 to the solid line position as shown in FIG. 1, and the connecting rod 5 is slid about the horizontal pin 19. A base end portion of the upper parallel link 6 is pivotally supported on the horizontal pin 19,
The turnbuckle connector 7 connects the middle part of the connection rod and the middle part of the connecting rod 5. The guide roller 9 can reciprocate by engaging the lower surface of the linear rail 2 to the arcuate rail 8 by the expansion and contraction of the cylinder 4, and the moving frame 3 can be horizontally moved along the lower linear rail 2. It can reciprocate on a straight line in any direction. Reference numeral 21 in the drawing indicates a parallel rod for reciprocating rotation of the lifting magnet 14, 22 a reciprocating rotating arm, 23 a reciprocating rotating cylinder of the arm 22, 24 a suspension chain of the guide 1 and 25 a moving frame. 3 is a horizontal holding roller, 26 in FIG. 3 is a charging hood, and 27 is a coal charging port. The linear rails 2 and 2
Are installed vertically, but one linear rail 2
It is also possible to support the moving frame 3 in a linear portion by using an arcuate rail 8 at its tip, and a guide roller 9 is provided on the horizontal pin 20 at the upper end of the connecting rod 5 at a level position in contact with the roller 9. It does not matter if the lower surface of the linear rail 2 to the arcuate rail 8 is arranged.

"Effects" Since the present invention is configured as described above, in the lid removing device for the coal charging port 27 of the coke oven 10, not only can the lid attaching / detaching work height of the device be formed low, but also the reciprocating frame 3 can be formed at a low position. It is possible to reciprocate horizontally, so that the installation space and the space for raising and lowering the charging hood can be made small, and the weight and the number of parts of the lid removing device can be reduced.
