The annealing furnace in the cold-rolled strip coil coating and galvanizing processing unit needs to be overhauled frequently. In the prior art, when the annealing furnace is overhauled, a steel pipe with a sleeve and a tether are temporarily installed on the top of the annealing furnace. Steel pipe, two hanging ropes are wound on the sleeve, one end of each hanging rope in the two hanging ropes is tied to the maintenance hanging frame temporarily placed in the furnace body, and the other end of the two hanging ropes is placed in the furnace body. The two operators are responsible for towing the upper part. When the maintenance hanging frame tied by the two slings is lowered to the proper position of the furnace body, the two slings are fastened to the tethered steel pipe on the top of the furnace body, and the maintenance personnel then Stand in the overhaul hanging frame to carry out the maintenance operation of the furnace body; the problems of the temporary lifting and hanging frame for the maintenance of the annealing furnace in the prior art are: (1). The overhaul hanging frame is in a suspended state in the furnace body, and the operator stands It is difficult to work in the inspection hanging frame, and the inspection hanging frame is easy to collide with the inner wall of the furnace body to cause new damage; (2). The lifting of the inspection hanging frame in the furnace body is controlled by two operators who tow the lifting rope. When the dragging force of the suspension rope is uneven, the maintenance hanging frame is prone to tipping over in the furnace body, and the maintenance operation has a great safety hazard; (3). Time-consuming, laborious, and low work efficiency. the

(3) Contents of the invention:

The purpose of this utility model is to solve the problems of the existing temporary hoisting frame for inspection and maintenance of annealing furnaces, such as the difficulty in swinging and repairing the hanging frame, the great safety hazards of the operators, and the low efficiency of the inspection and maintenance of the furnace body. Use a lifting device. the

The specific scheme of the utility model is: a lifting device for maintenance of an annealing furnace, which has an annealing furnace and a controller, and is characterized in that: a load beam is installed on the top of the annealing furnace, and three tie rings are arranged on the load beam. Two guide chains are respectively connected to the two tie rings, and the lower end of each guide chain is anchored with a tether pile fixed to the foundation; an electric hoist is installed on the middle tie ring, and a hanging frame is connected to the hook of the electric hoist , There are two vertically arranged guide grooves in the middle of both sides of the hanging frame, each guide groove is equipped with a pin hole, each pin hole is equipped with a safety lock pin, and the upper part of the hanging frame is also equipped with Hanging ring; the hanging frame is connected with the hook of the electric hoist at the hanging ring, and the hanging frame is installed with two guide slots and two guide chains. the

The load beam described in the utility model is arranged in the middle of the annealing furnace top, and the three tie rings are arranged symmetrically with the central axis of the annealing furnace on the load beam, and the vertical lines of the three tie rings 2 are arranged in the furnace body. the

The electric hoist described in the utility model is connected with a controller. the

Compared with the existing temporary hoisting frame for inspection and maintenance of the annealing furnace, the utility model is that a load beam is installed on the top of the annealing furnace, and two guide chains 4 and an electric hoist are respectively installed on the load beam by using tie rings. The electric hoist is equipped with a hanging frame, and the two guide grooves on both sides of the hanging frame 5 are combined with two guide chains to form a set, so that the hanging frame can be lifted and lowered smoothly in the annealing furnace; Each guide groove is equipped with two safety lock pins, when the hanging frame is lifted to a suitable height, the two safety lock pins are used to lock the hanging frame and the two guide chains, which can prevent the sliding of the hanging frame; the utility model The structure is simple, the operation is convenient, safe and reliable, and the maintenance operation efficiency is high; the utility model better solves the existing annealing furnace maintenance temporary lifting suspension frame existing in the suspension frame swing maintenance operation is difficult, the operator's safety hazard is large and the furnace The problem of low efficiency of physical maintenance work. the
