Embodiment Construction

[0021] The scheme will be described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] figure 2 It is a schematic diagram of a rubber compensator fixed by a blast furnace soft connection fixing device provided in the embodiment of this application, figure 2 The blast furnace soft connection fixing device in the figure fixes the rubber compensator 1 through the U-shaped fixing piece 4 . When fixing the rubber compensator 1 , the U-shaped fixing member 1 includes a plurality, which can be evenly arranged along the rubber compensator 1 .

[0023] see image 3 , the U-shaped fixture 4 includes a first side plate 5 and a second side plate 6, the first side plate 5 is provided with a threaded hole, corresponding to the threaded hole is provided with a screw 7, the screw 7 passes through the The threaded hole is threadedly connected with the first side plate 5 . When the rubber compensator 1 needs to be fixed, it can be realized by...

Abstract

The invention discloses a blast furnace soft connection fixing device and a use method thereof. The device comprises a U fixing part, the U fixing part comprises a first side plate and a second side plate, a thread hole is formed in the first side plate, a screw rod is arranged in a manner of corresponding to the thread hole, the screw rod is in threaded connection with the first side plate through the thread hole, when a rubber compensator needs to be mounted, only the U fixing part needs to be connected to an upper and lower flange, then the rubber compensator is laid on the second side plate, the screw rod is rotated to fix the rubber compensator. When the device needs to be dismounted, the screwed screw rod needs to be loosened reversely, through the fixing device, rapid dismounting and mounting of the rubber compensator can be achieved, and work efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of large-scale blast furnace top equipment, in particular to a blast furnace soft connection fixing device and a method for using the same. Background technique [0002] In large-scale blast furnace top equipment, the charging gate and the weighing tank are connected and sealed by components such as rubber compensators and dust covers. In the traditional technology, the upper end of the rubber compensator is fixedly connected with the feeding gate through the flange, and the lower end is fixedly connected with the dust cover through the flange. At present, the rubber compensator 1 is disassembled and replaced. According to the spare parts and technical requirements, such as figure 1 As shown, first remove the 64*2 bolts 3 connected to the upper and lower flanges through the bead 2, then remove the rubber compensator 1, replace and lay a new rubber compensator 1, on the rubber compensator 1, accord...
