Description

Flue overhauls auxiliary device

Technical Field

The utility model belongs to the technical field of steel industry climbing operation equipment makes, a novel quick platform of flue maintenance inspection is built device is related to.

Background

In the steel industry, a vaporization cooling flue system is an important component of converter smelting equipment, and the operation condition of the vaporization cooling flue system changes periodically and sharply along with the smelting process. The service life of the vaporization flue is inevitably greatly influenced under severe working conditions, and particularly, the failure rate is extremely high at the later stage of the service life of the flue, so that the furnace is frequently shut down for maintenance. Because the flue has a special internal structure and a severe working environment, a large amount of energy and time are needed to set up an operation platform before personnel start maintenance, at least 8-10 hours are needed, the maintenance time is too long, and the yield is further influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a problem to provide a flue overhauls auxiliary device to solve the long problem of current flue maintenance activity duration.

In order to solve the above problem, the utility model discloses a technical scheme is: including main ladder and vice ladder, main ladder with through many branch fixed connection between the vice ladder, the lower part of main ladder is connected with left pendulum branch through main lower gimbal, the lower part of vice ladder is connected with right pendulum branch through vice lower gimbal, main ladder with the upper portion of vice ladder is connected with the lower part of inclined ladder through main gimbal and vice upper gimbal respectively.

In the above technical solution, a more specific technical solution may also be: the two sides of the lower end of the inclined ladder are connected with the two sides of the upper part of the main ladder through two main upper universal supports, the two sides of the lower part of the inclined ladder are connected with the two sides of the upper part of the auxiliary ladder through two auxiliary upper universal supports, and the position of each auxiliary upper universal support is higher than that of each main upper universal support at the position of the main ladder.

Further: the two left-swing supporting rods are connected to two sides of the lower portion of the main ladder through the two main lower universal brackets.

Further: the two right-swing supporting rods are connected to two sides of the lower part of the auxiliary ladder through the two auxiliary lower universal brackets.

Further: the upper part of the inclined ladder is fixedly connected with a supporting rod.

Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has: not only have simple to operate, quick characteristics, compare in original need through the building of artifical one deck platform, greatly reduced staff's intensity of labour and risk coefficient. The left swing supporting rod and the right swing supporting rod can be flexibly extended according to the position of the flue to be maintained, powerful guarantee is provided for quick repair and overhaul of the flue, the influence of the sudden situation of the flue on the production yield is further reduced, and the benefit is remarkable.

Detailed Description

The invention will be described in more detail with reference to the following examples:

the flue maintenance auxiliary device shown in fig. 1 and 2 comprises a main ladder 1 and an auxiliary ladder 2, wherein the main ladder 1 is fixedly connected with the auxiliary ladder 2 through a plurality of support rods, the lower part of the main ladder 1 is connected with a left swing support rod 1-1 through a main lower universal support 1-2, the lower part of the auxiliary ladder 2 is connected with a right swing support rod 2-1 through an auxiliary lower universal support 2-2, and the upper parts of the main ladder 1 and the auxiliary ladder 2 are respectively connected with the lower part of an inclined ladder 3 through a main upper universal support 3-2 and an auxiliary upper universal support 3-3; the two sides of the lower end of the inclined ladder 3 are connected with the two sides of the upper part of the main ladder 1 through two main upper universal supports 3-2, the two sides of the lower part of the inclined ladder 3 are connected with the two sides of the upper part of the auxiliary ladder 2 through two auxiliary upper universal supports 3-3, and the position of the two auxiliary upper universal supports 3-3 on the auxiliary ladder 2 is higher than the position of the two main upper universal supports 3-2 on the main ladder 1; the two left swing support rods 1-1 are connected to two sides of the lower part of the main ladder 1 through two main lower universal brackets 1-2; the two right swing support rods 2-1 are connected to two sides of the lower part of the auxiliary ladder 2 through two auxiliary lower universal brackets 2-2; the upper part of the inclined ladder 3 is fixedly connected with a support rod 3-1.

When the device is used, the positions of the main upper universal support 3-2 and the auxiliary upper universal support 3-3 can be adjusted to adjust the inclination angle of the inclined ladder 3, the main ladder 1 is lowered to a converter support ring from an oxygen lance opening of a flue and is fixed by using a tower hoist crane, the support rod 3-1 at the upper part of the inclined ladder 3 is supported on the inner wall of the oxygen lance opening of the flue, a worker climbs to the main ladder 1 from the inclined ladder 3 and then climbs into the flue along the main ladder 1, the main lower universal support 1-2 and the auxiliary lower universal support 2-2 are adjusted to a part needing maintenance in the flue, and then the operation can be started by unfolding the two left swing support rods 1-1 and the two right swing support rods 2-1 to be supported on the inner wall of the flue. If need maintain the flue by a large scale, also can be with flue maintenance auxiliary device for keel frame, continue to set up the extension platform.
