Description

Repairing apparatus for making the working station move into the four directions}

The present invention relates to a furnace body repair device that enables the four-side movement of the workbench to facilitate the maintenance and repair work of the coke oven and the open door, and more specifically, the operator can move directly to the four sides to ride more quickly and safely The present invention relates to a body repair apparatus capable of moving in all directions on a work surface to perform work and repair work.

Generally, in order to obtain coke products, high-temperature drying is carried out in a state in which air is cut off by burning a fire at a lower part of the underjet system and transferring radiant heat to a carbonization chamber at a window side.

Meanwhile, in the process of burning gas as a heat source for 17 to 18 hours to produce high-strength coke at a temperature of about 1260 ° C, the silica lead built up inside the carbonization chamber is subjected to repeated shrinkage expansion and coking between bricks and bricks due to long time operation of the coke oven. Maltar, the lead of the world, is eliminated.

Therefore, to repair this, the bodywork repair work is performed using a scaffolding frame. However, in this maintenance work, not only a large number of workers are required to assemble and move the scaffolding frame but also a worker's fall risk, and the operation of the coke carbonization chamber must be stopped while such maintenance work is performed. do.

And, if the state of the maintenance work is poor, there is a problem that the life of the coke oven carbonization chamber is lowered, labor costs and coke cost rises.

In addition, the outflow of fresh gas caused by the inability to quickly maintain the open door is a major problem of the coke oven's maximum pollution, which has caused many problems in violation of comfortable coke operation.

In addition, the inefficiency of the work is generated repeatedly in the process of installation and dismantling and transport of the equipment by hand at the end of the work start.

The present invention was devised to solve the conventional problems as described above, the running wheels of the urethane friction rubbing the running wheels installed on the upper front of the carbonization chamber made of the left and right, the hydraulic motor (MOTOR) installed inside the panel In order to solve the problem of conventional inefficient work factors by operating the cylinder installed on the lower part of the workbench and lifting the workbench, all repair work can be performed more quickly and safely on the workbench. The object of the present invention is to provide a refurbishment device for moving the workbench on every side.

In order to achieve the above object, according to the present invention, the furnace maintenance device for enabling the four-side movement of the workbench to enable the maintenance work and repair work of the coke oven and the open door supports a guide for guiding the lifting and lowering of the workbench. A vertical frame and a horizontal movement driving means for moving the vertical frame along a horizontal direction of the carbonization chamber, and a driving wheel movable along the traveling rail provided on the upper front side of the carbonization chamber is provided at an upper end of the vertical frame. The driving wheel is made of a urethane material.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

According to the present invention, the 'H' shaped running rail 80 is installed at the upper end of the carbonization chamber, and the driving wheel 52 and the hydraulic motor made of circular urethane are provided at the top of the furnace repair device. At the bottom of the furnace repair device, a guide wheel 73 of a circular roller is installed at intervals of 1 m. The hydraulic motor installed on the top by the battery 20 for supplying power to the furnace maintenance device is rotated to drive the work.

The hydraulic motor installed inside the lower panel moves the cylinder 90 forwards and backwards, and the worktable 110 moves up and down in association with the movement.

Limit switch 30 is installed on the upper and lower parts of the transfer apparatus body to prevent excessive upward and downward.

All power is supplied from the rechargeable battery 20 installed in the furnace repair device. Rechargeable batteries are equipped with a charging adapter so that they always charge when the maintenance device is not in use to keep them running at all times. The charged battery supplies power to the traveling hydraulic motor, and the supplied hydraulic motor rotates the circular wheel 52 made of urethane provided on the upper part of the body repair device to friction with the traveling rail 80 installed at the top. Try to move forward and backward.

The running rail 80 installed at the top is fixed to the steel structure by bolt nuts at all times is fixed to the top of the coke oven front. Circular urethane wheel 52 installed on the top of the furnace repair device is manufactured to be assembled so that it can be replaced when worn.

A circular guide wheel 70 is installed at the bottom of the body repair device to prevent derailment of the body repair device during the forward and backward driving operation. The guide wheel 73 serves to reduce friction during driving.

The hydraulic motor installed in the furnace repair device lower panel 130 operates the cylinder 90 to raise and lower the work bench 110 so that the worker can safely work at the height. In order to prevent a sudden fall in the event of a facility, a check valve is installed, and the upper and lower limit switches are provided to prevent excessive lifting of the work bench 110.

The traveling control panel 40 inside the traveling lever is installed so that the operator can easily operate the body repair device in all directions.

In addition, the safety handrail 120 and the lifting ladder 121 is provided in the lower part of the furnace maintenance device in order to prevent the fall of the worker on the workbench.

The upper part of the body repair device is provided with shock absorbers (11a, 11b) to alleviate the impact when over-driving to protect the equipment in the event of a collision, prevents the fall of the operator by the impact and improves the life of the equipment.

Therefore, according to the present invention, since the present invention provides a furnace repair apparatus capable of moving arbitrarily up, down, left, and right installed in a coke carbonization chamber, it is possible to solve a problem incurred when repairing a furnace using a conventional scaffolding and work time. Due to the shortening, labor costs can be reduced, and in particular, the working time can be shortened and the carbonization chamber internal repair work and the open door maintenance work can be performed more quickly and safely.

The foregoing is merely illustrative of the preferred embodiments of the present invention, and those skilled in the art to which the present invention pertains may make modifications and changes to the present invention without departing from the spirit and gist of the present invention as set forth in the appended claims. It should be recognized.
