Description

Structure for preventing furnace door from dislocation

Technical Field

The utility model relates to a coke production is blocked burnt safe technical field, especially relates to a prevent furnace gate dislocation structure.

Background

The top-loading coke oven carbonization chamber is of a closed structure, the combustion chambers on two sides of the top-loading coke oven carbonization chamber are used for carrying out high-temperature dry distillation on the top-loading coke oven carbonization chamber, and when the coke is mature, a coke guide vehicle is required to take down the oven door of the carbonization chamber for coke guide operation. The door-taking trolley of the coke guide consists of a grasping structure, a stop iron and a driving device. The operation mode is as follows: 1. when the door taking trolley moves forwards upwards to the stop iron (the stop iron plays a limiting role), the door taking trolley stops moving forwards when the door taking trolley touches the furnace door cross iron; 2. the door taking trolley tightly grasps the furnace door by the structure; 3. the driving device of the door taking trolley drives the grasping structure to lift the door again and move the furnace door upwards; 4. the door-taking trolley starts to retreat and then reaches the initial limit position.

In the process of lifting the door by the door-taking trolley, the lifting hook on the door-taking trolley grasping structure and the furnace door cross bar move upwards together, and the position of the stop iron does not move along with the movement. Because the coke oven door frame and the edge of the oven door can generate or accumulate partial tar in the continuous production operation process of the coke oven, partial coke surface, tar residue and the like left over by an oven operator in the operation process can cause difficulty in falling of the oven door, the condition that the falling of the oven door and a hook of a door taking trolley is asynchronous occurs, a door pressing bolt on a grasping structure is returned at the moment, the cross iron of the oven door can be staggered and pushed against a stop iron of the door taking trolley, the door taking trolley can not operate the oven door, and the production interruption of the coke oven is caused.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem provide a guarantee furnace gate whereabouts in-process can not incline prevent furnace gate dislocation structure.

The utility model provides a technical scheme that its technical problem adopted is: the furnace door is vertically installed, the door taking trolley is provided with door taking trolley frames at the two horizontal ends of the furnace door, the furnace door is positioned between the door taking trolley frames, and the door taking trolley frames are parallel to the furnace door in the vertical direction; the furnace door is provided with a cross bar which is fixed with the furnace door and is horizontally installed, the door taking trolley is respectively provided with a stop iron on the door taking trolley frames at the two ends of the furnace door, the upper end surface of each stop iron is provided with a boss, the distance between the two bosses is adaptive to the length of the cross bar, and the height of each boss is adaptive to the lifting stroke height of the furnace door; when the furnace door moves, the transverse iron is arranged between the two bosses, and two end faces of the transverse iron are attached to the side faces of the bosses.

Further, the method comprises the following steps: the lug boss is fixedly connected with the stop iron.

Further, the method comprises the following steps: the lug boss and the stop iron are of an integrated structure.

The utility model has the advantages that: on the basis of the original limiting effect, the stop iron also plays a role in preventing the inclination of the furnace door due to the arrangement of the lug bosses, when the door taking trolley takes a door, the stop iron is not moved, the cross iron moves upwards along with the furnace door, and the two end surfaces of the cross iron are always attached to the side surfaces of the lug bosses on the stop iron at the two ends of the door taking trolley in the whole stroke, so that the inclination of the furnace door in the lifting stroke is prevented; the utility model discloses can directly stop the furnace gate cross bar top on getting a platform truck stop iron, lead to the furnace gate slope or damage the furnace gate, ensure production operation continuity, and the utility model discloses investment cost is very low, implements effectually, can improve production efficiency and extension coke oven life.

FIG. 2 is a schematic structural view of a stop iron and a boss of the furnace door dislocation preventing structure of the present invention;

labeled as: the furnace door comprises a furnace door 1, a door taking trolley 2, a cross iron 3 and a stop iron 4.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 to 2, the structure for preventing the dislocation of the furnace door of the present invention comprises a furnace door 1 and a door-taking trolley 2, wherein the furnace door 1 is vertically installed, the door-taking trolley 2 is provided with door-taking trolley frames at two horizontal ends of the furnace door 1, the furnace door 1 is located between the door-taking trolley frames, and the door-taking trolley frames are parallel to the furnace door 1 in the vertical direction; the furnace door 1 is provided with a cross iron 3 which is fixed with the furnace door 1 and is horizontally installed, the door taking trolley 2 is respectively provided with a stop iron 4 on the door taking trolley frames at two ends of the furnace door 1, the upper end surface of each stop iron 4 is provided with a boss, the distance between the two bosses is adaptive to the length of the cross iron 3, and the height of each boss is adaptive to the lifting stroke height of the furnace door 1; when the furnace door 1 moves, the cross iron 3 is arranged between the two bosses, and two end faces of the cross iron 3 are attached to the side faces of the bosses. The furnace door 1 moves upwards under the action of the pushing mechanism of the door taking trolley 2, and in the moving process, two end faces of the cross iron 3 are always attached to the side faces of the bosses, so that the furnace door 1 is limited in the horizontal position, and the phenomenon that the furnace door 1 cannot incline in the horizontal direction in the operation process is guaranteed.

Specifically, the boss and the stop iron 4 are fixedly connected, the cross iron 3 on the furnace door with different shapes, sizes and specifications can be replaced to adapt to other specifications, the fixing mode can be a buckle connection, the screw thread connection can also be adopted, and the purpose of fixing the boss on the stop iron 4 can be achieved.

Specifically, the boss and the stop iron 4 are of an integrated structure, so that the stability between the boss and the stop iron 4 is ensured, the boss is prevented from being dislocated on the stop iron 4, and the stability between the boss and the stop iron is improved.
