JPS59109583A - Device to stop coke oven operating machine in place - Google Patents

Abstract

PURPOSE:To stop a coke oven operating machine in place with high accuracy, by fixing a clamping device onto a rail and moving the machine in the running direction from the clamping device side by means of an actuator. CONSTITUTION:A truck 3 for a coke oven operating machine is attached to the bottom of a machine body frame 1 with a two-rod cylinder 5 which is fixed at an intermediate position under ordinary conditions of operation. When the machine is roughly set to the center line on which the machine is to be positioned, a rail 12 is fixed by a clamping device 4 and the truck 3 is fixed to the rail in the running direction by the clamping device 4 in this state. The discrepancy between the roughly set position and the oven center line is detected visually or by means of an oven center line sensor and the two-rod cylinder is set in motion so that rod (a) may go in and rod (b) may come out, leading to movement of the machine body frame 1 in X direction. When the rod (a) comes out and the rod (b) goes in, the machine body frame 1 moves in Y direction to be positioned in place with high accuracy.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a coke oven that allows for easy fine positioning when coke oven working machines, such as coke extruders, coal charging cars, etc., travel and align with the core of the coke oven chamber. This relates to a fixed position stop device for furnace-related working machines. .

The general driving method for coke oven working machines is as follows:
Although electric motors were used, when stopping the coke oven working machines on each core of the coke oven, the driver used an inching operation.

The stop position varies depending on the skill of the inching operation, and in bad cases, the furnace lid or charging lid may not come off, and you may have to perform inching again or again, or check that the machine is aligned with the furnace core. There were times when I needed an extra driving assistant.

In addition, as a conventionally known technique, in order to facilitate stopping at a fixed position, a fixed block is provided on the furnace side platform at a position that corresponds to the furnace core, and the fixed block is forcibly removed using appropriate clamping means with a hydraulic cylinder. There are some that force the fuselage to be positioned on the fixed block core by pinching it, and align it with the reactor core.

However, coke ovens constantly expand and contract due to thermal fluctuations within the oven, and as the years pass, the oven body deforms, and the fixed blocks do not necessarily align with the oven core. Furthermore, if driving is to be automated and unmanned, a fixed position stop device is essential, and its accuracy must be excellent, but this has not always been sufficient so far.

In order to solve the above-mentioned problems, the present invention is such that a clamp device is fixed to a rail, and the body is moved in the traveling direction by an actuator from the clamp device side.

A preferred embodiment of such a configuration will be described below. Reference numeral 1 designates a machine frame, from which a guide rail 2 is suspended, and a truck 3 is provided on the guide rail 2, which is movable in the running direction of the coke oven working machine. The truck 3Vc is provided with a clamp device 4.

The truck 3 is attached to the lower part of the fuselage frame 1 by both Rondo cylinders 5. The clamping device 4 has levers 7 and 7' pivotally supported by brackets 9 and 9' projecting from the truck 3 through pins 8 and 8', respectively, so that the clamp device 4 can rotate freely.

The lever 7,7' is connected at one end to the actuator 6 and is clampable.

Reference numeral 12 denotes a rail on which machines working around the coke oven run. In addition, 13 beams and rung materials such as hard rubber with a large friction coefficient are used. Alternatively, as shown in FIG. 6, it may be shaped to increase the frictional fixing force to prevent it from digging into the rail.

Next, we will discuss stopping at a fixed position. During steady running, the vehicle is in the state shown in Figure 1. Further, both rods and the cylinder 5 are fixed at intermediate positions. When the fuselage is roughly positioned in the reactor core, the clamping device 4 clamps the rail 12 as shown in FIG.
to clamp. In this state, the truck 3 is fixed to the rail in its running direction.

Next, the fuselage is equipped with a core detection sensor, which is visually inspected or by means of the driver's observation such as ITV, or in the case of automatic direction, to detect the rough position and misalignment of the core. enter.

When the rods a of both rondo cylinders 5 perform the actuation of the ejecting rod b, the fuselage frame 1 is moved in the direction of the arrow X in FIG. Furthermore, when the rod a is operated for the person and the rod b is operated for the out, the fuselage frame 1 similarly moves to the Y side, allowing highly accurate positioning of the fuselage frame 1.

As described above, according to the present invention: 1) There is no need for a fixed block that must be installed on the coke oven side as in the past.

2) Since the positioning of the fuselage frame relative to the furnace core is performed by feedback of the actual detection of the furnace core as seen from the fuselage side, the positioning of the fuselage frame can be achieved with high precision and flexibility.
