Description

Technical Field

[0001] The invention belongs to the technical field of converter equipment installation, and in particular relates to a steelmaking continuous casting plant roof dust removal pipeline installation structure and a use method thereof. Background Art

[0002] The dust removal ducts on the roof of the steelmaking continuous casting plant are installed in the pipe supports above the longitudinal beams of the roof steel structure.

[0057] The present invention also provides a method for using a steelmaking continuous casting plant roof dust removal pipeline installation structure, comprising the following steps:

[0058] S1. Installing pipe supports 3: After installing the steel structure roof longitudinal beams 1 and roof transverse beams 2 of the steel continuous casting plant, install pipe supports 3 in the dust removal duct installation area 100. Install both the pipe support 3 bracket and the arc-shaped support plate 32. Install only the pipe support 3 bracket in the dust removal duct assembly area 200, without installing the arc-shaped support plate 32.

[0059] S2. Installation of transport bracket:

[0060] S3, installation of the horizontal push bracket 5;

[0061] S4. Install the trolley 8: Use the two rail beams 43 of the transport bracket as the running track of the trolley 8. Install the trolley 8 on the two rail beams 43 to transport the dust removal pipe. The top of the trolley 8 is flush with the longitudinal beam 53 of the horizontal push bracket 5.

[0062] S4. Assemble the dust removal duct 10: Hoist the dust removal duct 10 onto the top of the trolley 8 and transport it to the position via the track beam 43. Then, roll the dust removal duct 10 onto the longitudinal beam 53 so that the center of the dust removal duct 10 coincides with the center of the pipe support 3. Roll multiple sections of the dust removal duct 10 into position and connect them to form an integral duct.

[0063] S5. Pulling the dust removal duct 10 into place: A hoist 9 is installed on the roof longitudinal beam 1 on one side of the steelmaking continuous casting plant roof. The hoist 9 pulls the integral duct assembled on the longitudinal beam 53 to the dust removal duct installation area 100. The integral duct is sequentially brought into contact with the roller assemblies 33 located on the sides of the arc-shaped support plate 32. Guided by the roller assemblies 33, the integral duct is pulled into position above the installed arc-shaped support plate 32 in the dust removal duct installation area 100.

[0064] S6. Remove the roller assembly 33: When all the pipe supports 3 with the arc-shaped support plates 32 installed in the dust removal pipe installation area 100 are covered with dust removal pipes 10, remove the roller assembly 33 so that the dust removal pipes are completely located on the arc-shaped support plates 32;

[0065] S7, installation of the dust removal ducts in the dust removal duct grouping area 200 and installation of the arc-shaped support plate 32;

[0066] S8. Remove the transport bracket 4 and the horizontal push bracket 5, and the dust removal duct installation work is completed.

[0067] The force support points of the transport bracket 4 and the horizontal pushing bracket 5 are both located on the roof longitudinal beam 1. The roof longitudinal beam 1 is a heavy steel structure beam with high supporting strength; multiple sections of dust removal pipes are combined together on the horizontal pushing bracket 5 and pulled into place as a whole, which improves construction efficiency; a roller assembly 33 is arranged on the arc support plate 32 to assist in pulling the dust removal pipe and reduce friction resistance. The roller assembly 33 is simple to set and highly operational; the transport columns 41, connecting beams 42, track beams 43 of the transport bracket 4 and the cross beams 51, cross pushing columns 52, and longitudinal beams 53 of the horizontal pushing bracket 5 are all light steel structures and can be installed manually without the assistance of lifting machinery. The longitudinal beam 53 is slightly higher than the lowest point of the arc of the arc support plate 32, and will not hinder the traction of the dust removal pipe in the dust removal pipe installation area 100. The top of the longitudinal beam 53 is higher than the top of the pipe support 3 bracket, which facilitates the subsequent installation of the arc support plate 32 in the dust removal pipe teaming area 200.

[0068] The present invention adopts the structure of the transport bracket 4, the horizontal pushing bracket 5 and the pipe support 3 and the use method thereof, so that the dust removal duct can be quickly installed when the roof beam 2 has been installed. The factory roof structure cannot be closed in time due to the reserved factory roof beam 2 not being installed, which seriously affects the construction period. At the same time, when the dust removal duct on the continuous casting factory roof is replaced and repaired during the maintenance project, the roof beam 2 does not need to be removed, and the normal operation of the production crane in the factory will not be affected.

[0069] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
