Main tool and auxiliary tool for opening and closing spring cover of coke oven and opening and closing method

Abstract

The invention discloses a main tool and an auxiliary tool for opening and closing a spring cover a coke oven and an opening and closing method. The main tool comprises a main clamping beam, an adjusting jackscrew hole ring is arranged in the middle of the main clamping beam, a gripper is arranged at the relative position of the adjusting jackscrew hole ring, and fixing rings are arranged at the two ends of the main clamping beam and used for fixing and supporting. The auxiliary tool for opening and closing a spring cover of a coke oven comprises a connecting rod, a handle is arranged at one end of the connecting rod, a hook is arranged at the other end of the connecting rod, an arc-shaped support is arranged between the handle and the hook and close to the end where the hook is located, and an opening of the arc-shaped support faces the hook. The opening and closing method for opening and closing a spring cover of a coke oven comprises the steps that the main clamping beam of the maintool is clamped to the edge of a vertical beam of a steel column, and the adjusting jackscrew hole ring is clamped into a reserved measuring and adjusting hole of the steel column; the hook of the auxiliary tool extends into the fixing rings; and the hook is hooked on the spring cover gripper by moving the handle, so that a spring cover is lifted and placed on a spring set by taking the fixing rings as fulcrums and by means of lever force, and the arc-shaped bracket is inserted into the spring cover gripper to fix the spring cover gripper.

Description

technical field [0001] The invention belongs to the technical field of coke oven protection, and in particular relates to a main tool, an auxiliary tool and an opening and closing method for a coke oven opening and closing spring cover. Background technique [0002] Among the Italian-designed PW 7.29-meter large coke oven protection iron parts, the biggest feature is that the protection plate is divided into four sections, the protection plate is pasted on the outer surface of the coke oven to protect the furnace body, and the steel column is pressed on the protection plate. The column and the protective plate are supported by top wires, which is a feature of the non-adjacent method. These top wires exert sufficient pressure through the spring group to keep the protection plate always attached to the furnace wall. In order to protect the tightness and firmness of the coke oven and prolong the service life of the coke oven, we need to measure and adjust the spring set regular...

Problems solved by technology

In the previous measurement and adjustment, these spring covers can only be opened and closed by manual lifting method. Due to the weight of these iron covers is relatively heavy, the operating space is small, the operating distance is long, coupled with the large number and high-altitude operations, safety Low, heavy labor, making the work efficiency low
