Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of overhauling equipment, and particularly relates to a furnace lining overhauling platform. BACKGROUND

[0002] During the lining process of converter overhaul, a temporary platform needs to be erected at the refractory lining position of the furnace body for the convenience of personnel operation. If a fixed platform is used, it is inconvenient for operation, and only a movable platform can be used when lifting. Due to the small furnace mouth and large furnace body, the platform needs to be designed to be detachable and capable of entering the furnace from the furnace mouth. UTILITARY MODEL CONTENTS

[0003] The technical problem solved by the utility model is that the utility model provides a furnace lining overhauling platform, which has the functions of lifting and moving and being detachable, can enter the furnace from the furnace mouth, and is convenient for workers to perform lining work.

[0004] Technical scheme: A furnace lining overhauling platform comprises a crossbeam, a furnace-entering platform, an outer ring platform and a hoisting guide chain. The crossbeam is arranged above the furnace mouth. The diameter of the furnace-entering platform is smaller than the caliber of the furnace mouth. The outer ring platform is connected to the outer periphery of the furnace-entering platform through flanges. After the outer ring platform is connected, the diameter of the overhauling platform is equal to the inner diameter of the furnace body. The two ends of the hoisting guide chain are connected to the furnace-entering platform and the crossbeam respectively, and the hoisting guide chain is used to lift the overhauling platform.

[0005] Preferably, the furnace-entering platform is a circular platform.

[0006] Preferably, the outer ring platform is composed of a plurality of sector plates.

[0007] Further, the sector plate is provided with eight sector plates.

[0008] Preferably, the hoisting guide chain is not less than three.

[0009] Further, the hoisting guide chain is provided with four.

[0010] Preferably, the overhauling platform is further provided with a safety rope overlapping the position of the hoisting guide chain.

[0011] Further, the safety rope is a steel wire rope.

[0012] Beneficial effects: the utility model discloses a kind of detachable temporary maintenance platform, can satisfy the demand of furnace building operation.Specifically, by the furnace entry platform smaller than furnace mouth caliber, it can smoothly enter the inside of furnace body with small mouth and big belly;By the detachable setting outer ring platform, it can smoothly carry out furnace building operation in furnace;At the same time, since the outer ring platform is installed and equivalent with furnace body inner diameter, further enhance the stability of maintenance platform, increase the activity space of staff, improve the operation safety of staff;By lifting guide chain, the flexible lifting of maintenance platform can be realized, and the safety rope additionally provided can prevent the stability problem of maintenance platform caused by accidental fracture of lifting guide chain. BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 It is the overhead structure schematic diagram of the utility model;

[0014] Figure 2 It is the side structure schematic diagram of the utility model;

[0015] Each number in the drawing represents the following meaning:1. furnace entry platform, 2. peripheral platform, 3. lifting guide chain, 4. safety rope, 5. crossbeam. DETAILED DESCRIPTION

[0016] The utility model is further described below in connection with the drawings and specific embodiment. Example 1

[0017] As shown in Figure 1 And Figure 2 , a furnace building maintenance platform includes crossbeam 5, furnace entry platform 1, outer ring platform 2 and lifting guide chain 3.The crossbeam 5 is erected above the furnace mouth.The furnace entry platform 1 is circular platform, and its diameter is less than the caliber of furnace mouth, to facilitate entering the furnace.The outer ring platform 2 is detachably connected to the outer periphery of furnace entry platform 1 through flange, and the diameter of maintenance platform after connecting outer ring platform 2 is equal to the inner diameter of furnace body.Referring to Figure 1 , outer ring platform 2 is composed of 8 sector plates in the embodiment.The two ends of lifting guide chain 3 are connected with furnace entry platform 1 and crossbeam 5 respectively, for lifting maintenance platform.Lifting guide chain 3 is not less than 3, and 4 are provided in the embodiment.
