Abstract

This invention relates to a coke industry and allows an increase in the reliability of operation of coke oven door closures. The shutter includes a spring-loaded lever mounted on the door body can be rotated about a horizontal axis, bolt shaft, locked, worn on a spring-loaded lever with the ability to move along the fish. chaga, staples mounted on a bolt shaft and interacting with frame supports. The shutter is equipped with cranks mounted on the shafts of the bolt shaft, an emphasis fixed on the door body and interacting with a spring-loaded lever, eyelets hinged on the shank of the bolt shaft and covering the brackets so that they can be moved in a vertical plane, the brackets are connected hingedly to the cranks, hinges The connection of the cranks with the bolt shaft is located between the frame stops and the hinge of the clamp fastening on the crank. The shutter provides a reduction in the loads applied to the bolt shaft and, consequently, to the double-opening device, which provides an increase in the reliability of operation of all elements of the interacting structures. 6 Il. i (lu 00 od about 0

Description

The invention relates to equipment for coke production, in particular to coke oven door closures.

The purpose of the invention is to increase the reliability of

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. in fig. 4 is a section bb In figure 1; in fig. 5 shows a kinematic diagram of the shutter in the open state; Fig. 6 shows the closed state.

The gate of the coke oven includes a spring-loaded lever 1 fixed on the body of the door 2 rotatably about a horizontal axis 3, a rig shaft 4 with shanks 5 mounted on a spring-loaded lever 1 rotatable along the lever 1, brackets 6 mounted on a cross shaft 4 and interacting with the lugs 7 of the frame 8, cranks 9, lock

prisoners hinged on the shanks 5 of the transom shaft 4, the stop 10 fixed on the door body 2 and interacting with the spring-loaded lever 1, shackles 11 hinged on the shanks 5 of the transom shaft 4 and covering the brackets 6 with the possibility of their movement in the vertical plane, the brackets 6 are connected hinged with cranks 9, and the hinge 12 connecting the cranks 9 with the ram shaft 4 is located between the stops 7 of the frame 8 and the hinge 13 of the clamp 6 on the crank 9. Opening and closing the shutter is carried out using a fork 14 of the mechanism 3 pick the doors of the coking machine.

The device works as follows.

In the open position, the door is held by gripping the door break mechanism (not shown). In this case, the fork 14 of the mechanism for locking the doors of the coking machine is in the upper position and interacts with the bolt shaft 4, and the elements of the device are in the position shown in FIG. 5, After the door 2 is installed in the coke oven frame 8, the fork 14 goes down, moves the locking shaft 4 in the same direction, while the spring-loaded lever 1 rotates about horizontal axis 3, locking shaft; 4 with the straps 11 mounted on the shank 5, the brackets 6, opi

The earrings 11 are rotated relative to the hinge 13 and encompass the stops 7 of the frame 8.

With further movement due to a change in the relative position of the spring-loaded lever 1, the bolt shaft 4, the curved shaft 9 and the brackets 6, the springs of the spring-loaded lever 1 begin to compress and the bolt shaft 4 moves along the lever 1. The movement takes place until the spring-loaded lever 1 reaches the stop 10, while the lever system passes the dead center position (when the clamp 6, the spring-loaded lever 1, the crank 9 and the hinges 12, 13 are in line) and the spring of the spring-loaded fish | Chaga 1 remains compressed, due to which pressing the door to the frame.

Claims (1)

The doors are opened in the reverse order: the fork 14 moves the bolt shaft 4 up, the spring-loaded lever 1 moves as far as the stop 10, the lever system rotates, passes the dead center position, the bolt shaft 4, moves along the spring-loaded lever 1, returns to its original position, An earring 11, when moving upwards, approaches the bracket 6 and lifts it, disengaging from the stops 7 of the frame 8. Invention formula The gate of the coke oven door, which includes a spring-loaded lever mounted on the door body, can be rotated around a horizontal axis, a rigid shaft mounted on a spring-loaded lever that can be moved along the lever, brackets mounted on the transom shaft and interacting with the frame stops, characterized in that in order to increase reliability, the shutter is equipped with cranks mounted on the shafts of the bolt shaft, with an emphasis fixed on the door body and interacting with a spring-loaded lever, earrings, gash - Nirno attached to the shank of the bolt shaft and enclosing the brackets with the possibility of their movement in the vertical plane the brackets are connected hingedly to the cranks and the hinge connecting the cranks with the bolt shaft is located between the frame stops and the hinge of the bracket fastening on the crank. n View in Fig.Z L Editor M.
