Description

  The present invention relates to a guide car for a coke oven provided with a guide lattice for guiding and conveying coke pushed out of the furnace by an extruder to a bucket car.

  Conventionally, this type of coke oven guide car includes a traveling carriage provided on the guide side of the coke oven so as to be movable along the direction of the furnace group, and a furnace lid desorption device mounted in parallel with the traveling carriage. In addition, a so-called two-point guide wheel composed of a guide grid is known. In this two-point guide car, the center of gravity is biased to the opposite side of the furnace port with respect to the traveling carriage due to the arrangement of the furnace lid detaching device and the guide grid, so that the furnace is more than the load on each wheel on the furnace opening side of the traveling carriage. The load on each wheel on the opposite side of the mouth is large.

  On the other hand, in order to solve the above-mentioned deviation of the center of gravity, the inner frame is provided on the traveling carriage so as to be movable in the direction of the furnace group, and the furnace lid detachment apparatus and the guide grid are positioned so that the weight of the furnace lid detachment apparatus and the guide grid is located from the furnace port. A so-called one-point guide wheel has been developed in which the device and the guide lattice are suspended from the inner frame.

  However, since the center of gravity of the conventional one-point guide wheel is located at the approximate center of the guide wheel, the deviation of the center of gravity can be eliminated, but the installation space for the moving device for moving the inner frame in the direction of the furnace group is secured. There is a problem that it is larger than the two-point guide vehicle and cannot be reduced in size and weight. Recently, there is a demand for further reducing the load on each wheel of the traveling carriage.

  In view of the above problems, an object of the present invention is to provide a coke oven guide wheel that can be reduced in size and weight while eliminating the deviation of the center of gravity.

In order to solve the above-described problems, according to the coke oven guide car according to the present invention, the traveling cart 10 is provided on the guide side of the coke oven 1 so as to be movable along the furnace cluster direction. An inner frame 20 is provided so as to be movable in the direction, and a plurality of coke oven working devices A to C are arranged in parallel on the inner frame 20, and the coke oven working devices A to C are suspended from the inner frame 20. It is configured to reciprocate in the furnace length direction in the installed state, and further, each coke oven work equipment A to C faces the furnace port 3 of the coke oven 1 by moving the inner frame 20 in the furnace group direction. In the coke oven guide car configured to be located at a position and a retreat position for retreating from the work position, the inner platform in the travel cart 10 is configured so that the travel cart 10 and the inner frame 20 can move together. Movement space in the direction of the furnace group of the frame 20 Eliminate scan, by the movement of the traveling carriage 10, the respective coke oven working equipment A through C, and adapted to be positioned in said retracted position and said working position, the traveling carriage 10, at a predetermined distance It is composed of a pair of carriages 11, 11 that are connected and move along rails 7 that are laid along the furnace group direction, and a suspension machine frame 30 that is erected across the two carriages 11, 11, The inner frame 20 is arranged along the furnace length direction and is fixed to the upper frame 32 of the hanging machine frame 30, and the end of the parallel rail 22 opposite to the furnace port 3. Is composed of an upright support portion 21b that hangs down toward the rail 7 located between the two carriages 11 and 11, and a wheel 24a that can travel with respect to the rail 7 provided at the lower end of the upright support portion 21b. The coke oven working equipment A to C In, suspended possible and movable suspended moving means are provided for parallel rails 22, in the parallel rails 22, that each coke oven working equipment A~C is suspended at the position of the furnace opening 3 Features.

  In this case, by eliminating the movement space of the inner frame 20 in the traveling carriage 10, the length of the traveling carriage 10 in the furnace group direction can be reduced, and it is smaller and lighter than the existing two-point guide car.

Furthermore, in this case, the parallel rail 22 of the inner frame 20 is fixed to the upper frame 32 of the hanging machine frame 30 of the traveling carriage 10, and the wheel 24 a that travels the rail 7 on the side opposite to the furnace port 3 is provided. Since it provided, the traveling trolley | bogie 10 and the inner underframe 20 come to move together. Further, in the parallel rail 22, the coke oven working devices A to C are suspended from the furnace port 3, and the loads of the coke oven working devices A to C are applied to the rail 7 by the wheels 24 a of the inner frame 20. As a result, in addition to the fact that the overall center of gravity is not biased, the load on each wheel of the traveling carriage 10 is further reduced, and each coke oven work equipment A is more than the existing one-point guide car. -C and the traveling cart 10 can be moved in a more stable state.

  As described above, according to the present invention, there is no space for moving the inner frame in the traveling carriage, so that the size and weight can be reduced. In addition, since the traveling carriage and the inner frame move together, the centering work of each coke oven working device can be performed only by the movement control of the traveling carriage, and a series of operations can be performed smoothly and quickly. is there.

  Hereinafter, a coke oven guide wheel according to an embodiment of the present invention will be described. For convenience, the configuration of the coke oven will be described first. A part of the configuration is shown in FIGS. The coke oven 1 is formed by penetrating along the furnace length direction, and a plurality of carbonization chambers 2 arranged in parallel in the furnace group direction, one end side (extrusion start end side) and the other end side of each carbonization chamber 2.
