Description

The invention relates to the anchor of coke ovens, and more specifically to a transverse anchorage of a coke oven battery with any volume of oven chambers.

The aim of the invention is to increase the efficiency

Fig. 1 shows a cross-sectional anchorage of a coke-oven battery, the side view of Fig „2 - section A-A in Fig. |.

The transverse anchorage has a series of anchor columns 1 and 2, respectively from the coke and engine sides of the battery. Columns 1 to 2 are installed with anchor bolts 3 on the base plate of the furnace. The angular two shoulders of the hinges 4 with the pushers 5 placed in the guide holes of the columns are pivotally mounted inside the an-anker column. Upper (almost goe in

The horizontal arms of the levers 4 interact with the springs 6 mounted on a common adjusting rod 7 using adjusting nuts 8. Ta 7 is pivotally connected to the direct horizontal contour lever 9 pivotally attached at the bottom of the columns. The lever 4, the pusher 5 and the spring 6 bind the spring device, and all the gun devices of one column, together with the thrust 7 and the nuts 8, form the clamping system of the column

In the upper part of columns 1 and 2, there are mounted hinged angular two shoulders levers 10, the upper shoulders of which are connected pivotally to the fixed device 11, by means of which all anchor columns of a coke battery are connected in pairs (one column of coke jO side and one column of machine section). batteries), the lower shoulders of the levers 10 and the levers 9 are connected by power adjusting rods, which on the coke side are formed by sections 12 and 13 connected by means of threaded couplings 14, and on the machine side by section 15 and the hydraulic cylinder 16 connected to it. ufta hydraulic cylinder 14 and 16 perform the functions regulator TO- pit length m of the adjustment arrangement described provides lateral anke- movable rage compound zhnyh art devices masonry furnace.

The rod end of the hydraulic cylinders 16 is constantly connected to the pressure main pipe 17, and

reciprocating with drain pipe 18. These connections are through hoses. The pressure pipe 17 is connected to the cargo battery 19, which provides a constant predetermined pressure in the pipeline, the battery 19 is charged as required by the station 20 with working fluid from the Naive tank 21. Valves are provided for repairs.55

Cross ankerage works as follows.

water 17 into the rod end of the hydraulic cylinder 16 and tends to move its piston and thus enlarge this cavity, i.e. shorten the length of the power adjustment gi. At the same time, from the force of the hydraulic cylinder 16 on one side, through the lever 9 and tu 7, the springs 6 are compressed, the forces of which are transmitted by the levers 4 to the pushers 5, which, in turn, transmit the forces to the furnace reinforcement (armor, etc.) On the other hand, the force from the hydraulic cylinder 16 through the puller 15 and the angular lever 10 ne |) goes to the tensioning device 11, then to the angular lever 10 of the column 1 and through the threaded coupling 14, the lever 9 to the adjusting rod 7, the pressure system of the column 1 coke side. From this clamping system, the force also flows through the reinforcement to the furnace wall. Thus

Therefore, the anchoring force in this pair of columns closes. Since the pressure in the hydraulic cylinder is kept constant, when changing the length of the rod of the clamping device (for example, in summer and in winter), the forces in the closed anchor-force system remain almost unchanged, but the volume of the rod cavity also changes.

As the furnace grows from the masonry movements (approximately 7 mm per year per side), the pushers 5, through the levers 4, tend to compress the springs 6 and thus increase their forces. However, due to the constant pressure B of the hydraulic cylinder, the springs are not compressed (and consequently, their forces do not increase), but the volume of the rod end of the hydraulic cylinder decreases. Since all the hydraulic cylinders of all the columns are connected to the pressure pipe, these phenomena occur in anchoring all over the battery. In this way, automatic maintenance of the predetermined forces in the anchorage is provided.

The application of the invention makes it possible to improve the quality of work of the anchorage, as it provides for a practically constant, predetermined force effect on the laying of the furnace. As a result, the service life of the coke-oven battery is increased by at least 2 years, the pollution of the environment is reduced, the performance of the Coke-oven battery is increased by reducing the cycle of personal stops by at least 5 hours per day required for 5151

liver normal working ankerage.

Reducing cyclical stops is possible as a result of the fact that the new anchorage eliminates a number of complex and time-consuming service practices, such as testing and adjusting the forces on the upper anchor bolts and spring devices of the columns, checking the deflection of the columns and making dp of these operations for special devices.
