Embodiment 1

[0030] Embodiment 1, a kind of tension straightening machine of modular structure of the present embodiment, refer to Figures 1 to 5 As shown, it includes: a lower base module 11 and an upper frame module 12 .

[0031] The lower base module 11 takes the base module 111 as the core, and the lower roller table assembly module 112 is installed on the base module 111; the lower transmission device module 114 is installed on the base module 111 through lugs and pins, and assembled with the lower roller table through bushings The roller shafts of the module 112 cooperate to drive the roller shafts of the lower roller table assembly module 112 to rotate; the water-cooled protective cover module 113 is also installed on the base module 111 to cover the lower roller table assembly module 112 as a whole and play a role of cooling protection. The upper frame module 12 takes the frame module 121 as the core, and the upper roller table assembly module 122 is installed on the frame module ...

Embodiment 2

[0032] Embodiment 2, a kind of tension straightening machine of modular structure of this embodiment, refer to Figures 6 to 9 shown.

[0033] In the specific implementation, when a part of the tension leveler breaks down, use the continuous casting machine to change the pouring time, open the quick locking device of the tension leveler, turn off energy media such as water, oil, electricity, etc., and disassemble the pipe joints. Lift out the tension leveler as a whole from the vertical direction, hoist the new tension leveler, use the alignment device for quick alignment, after the piles are in place, install the pipe joints, open the energy medium, and control the quick locking device of the tension leveler to lock.

[0034] Lift the tension leveler after offline to the maintenance area, remove the nuts 23 of the T-bolts connecting the base and the frame, disassemble the hydraulic hard pipe clamp 24, and decompose the tension leveler as a whole into the lower base module 21...

Embodiment 3

[0039] Embodiment 3, the overhaul method of the modular structure tension leveler of the present embodiment is implemented by the tension leveler of the modular structure of the above-mentioned embodiment 2, see Figure 10 shown, including the following steps:

[0040] S31. Steps for the overall replacement of the tension leveler

[0041] When a part of the tension leveler breaks down, use the continuous casting machine to change the pouring time, open the quick locking device of the tension leveler, turn off energy media such as water, oil, electricity, etc., disassemble the piping joints, and pull the tension leveler from the Lift out the whole in the vertical direction, lift the new tension leveler, and use the alignment device to quickly align it. After the pile is in place, install the pipe joints, open the energy medium, and control the quick locking device of the tension leveler to lock.

[0042] S32, the step of removing the module to which the faulty component belong...

Abstract

The invention discloses a withdrawal and straightening machine of a modular structure and an overhauling method thereof and aims to solve the problems that an existing continuous casting withdrawal and straightening machine is complicated in overhauling process, low in efficiency and long in time spent and thus the withdrawal and straightening machine cannot be overhauled quickly. The withdrawal and straightening machine comprises an upper rack module and a lower base module, wherein the upper rack module comprises a rack module, an upper roller way assembly module, a hydraulic cylinder moduleand an upper transmission device module; and the lower base module comprises a base module, a lower roller way assembly module, a water cooling protective cover module and a lower transmission devicemodule. The method comprises: the to-be-overhauled withdrawal and straightening machine unloaded from a line is hoisted to an overhauling area; the to-be-overhauled withdrawal and straightening machine is dismounted into the upper rack module and the lower base module; and modules to which fault parts and components belong are dismounted and corresponding new modules are installed; and the withdrawal and straightening machine of the modular structure is used for implementation. The machine and the method disclosed by the invention can effectively realize functions such as rapid and efficiencyoverhauling of the withdrawal and straightening machine, a high spare part turnover rate, and low cost in overhauling and spare parts.

Description

technical field [0001] The invention relates to the technical field of tension leveler maintenance, in particular to a tension leveler with a modular structure and a maintenance method thereof. Background technique [0002] The tension leveler is the key equipment in the continuous casting production, which is closely related to the operating rate of the continuous casting machine. At present, domestic steel mills generally have problems such as lack of integrity in the structure of the tension leveling machine, heavy maintenance work, and long time consumption, which have a great impact on the maintenance efficiency of the tension leveler and the overall operation rate of the casting machine. The specific performance is: [0003] First, there are many and scattered components of the transmission device: in the transmission device of a conventional tension leveler, the motor and the first-stage reducer are installed on the upper platform, the second-stage reducer is install...
