Description

one

Inventions related to coking plants. promyengos ;,. specifically for devices for installation and coke oven door safety.

It is known to install and remove doors of coke ovens, including chugangu, studs, the upper end of which is rigidly fixed to the rod and fixed to it with the possibility of moving along the horizontal axis of the rod, hooks with a drive of vertical spacer and mechanical release and output; 1; mounted on the rack.

The disadvantages of the known construction are the laboriousness of the manufacture of guide pillars, the difficulty of exhguatacin due to the provision of periodic c: smears and the unreliability of the hydraulic drive.

The purpose of the invention is to increase reliability in operation.

This goal is achieved by the fact that in a device for installing and removing coke oven doors, including a rod, a rack, the upper end of which is rigidly fixed to the rod and the lower one is fixed on it with the possibility of movement along the horizontal axis and the gang.

vertical movement hooks and mechanisms for annealing and lifting bolts mounted on a rack, vertical holes are made in the rack, each hook is made with a vertical guide surface, with a sleeve mounted in the rack hole, and a vertical movement drive located in the sleeve is connected to it by means of a ball pin, and the mechanism for the release and withdrawal of the transom is mounted on a rack Fixed.

FIG. 1 shows the door-opening device, general view; in fig. 2 - auxiliary cylinder unit with a hook.

The device consists of a movable rod 1 installed in the rollers 2. In the rod 1 there is a fixed strut 3 with an upper hinge fixed support 4 and a lower hinge support 5 that does not move in the horizontal-horizontal plane, and a cabin 6 with a pump station located in it.

On the pillar 3 fixedly installed two mechanisms of release and output bolts, made in the form of a hydraulic cylinder 7,

contacting 1e with 11-latch bolts S dari 9 ii two ns 11 gates 1 hydr01 OR} Dra 10. Each hook 11 is mounted with a bearing 12 on the sleeve 13, which is located in the guide hole 14 made in the rack at 3 and the ball 1 is co-soglneia rod 15 auxiliary hydraulic cylinder 10.

Each hook 11 is vertical with: a vertical surface 16 serving as a luifl pin to stop the coke oven oven door, as well as to achieve a parallel turntable 3 and coke oven door 9.

The dimetre of the ipoka 17 squeeze gauge 7 is taken equal to the sum of the vozglozhu.ch reproducible deviations of the door 9 from its nominal size and 5W; In addition, it provides lIop utyl contact for the second person with the press 17 of the squeeze hydrodynamic 7 and spring bolts 8, which are attached to the bar 18. Dzer 9 has a Pin and upper fingers 19 and 20. Fixed position of the door 9 O.rMocHTCjnjho frame 21 is achieved by mounting it on the stops 22 of the furnace frame 21.

The device is working in the following way.

With the door hinge 9 from the oven frame 21 of the pianus 1 with the forward, pivoting stand 3, it goes to the furnace before the rear hour of the lower hook from the 19th pillar 9 contacts.

Upon further movement of rod 1, collar 3 will be deployed around yi daego paped 19 dajri 9 until the top hook 16 of the upper hook directed the upper hook 20 of the door 9. In the case of non-scratch positioning of the fingers 19 and 20 The doors 9 of the hooks 11 turn to turn the latter into a horizontal flat STP along with the type 13 in the iiiRcp fires of the pivot pole 3. Thus, due to the lower support 5 being moved in the horizontal plane during the burning of its liny wrench, the pivot stand is self-installed 3 on the door 9 coking nem and reaches their paralleloon location.

After stopping pganga 1, iodine occurs. hooks) 1 on the abutment of the fingers 19 and 20 dzeri 9. At the same time, the rods J7 midrange;: kynyh and -...; The 7 cylinders are always positioned against Fri.; the door bolts are released 8, which are deployed by acting on a string of 18 special ones; After that, the hydrodilidyr 7 is returned to the original; more In the work come in the wide range; 10.1, which tear down the door with the stop 22 of the frame 21 and press it up 10 cm. Then, the pivot post 3 together with the door 9 is retracted or neiffl 1nta1Goy 1, rotated 180 ° and into the door cleaning mechanism.

The door is installed in the reverse order; instead of a breakdown, the door ne4iioii is landing on the stops 22 of the furnace frame 21.

The proposed device makes it possible to increase the reliability in operation due to the fact that the hooks are installed with the possibility of vertical movement and rotation around the vertical axis.
