[0023] Please see Figures 1-6 As shown, the main body of this embodiment is an annealing furnace 1 and a sandblasting room 3 structure for on-site fabrication and installation of extra-large equipment. It is applied to extra-large equipment that requires on-site completion of annealing and sandblasting processes. The specific technical solution is as follows: Furthermore, the annealing furnace 1 and the sandblasting room 3 are arranged sequentially along the on-site operation axis, specifically including the annealing furnace 1, the power supply area 2, and the sandblasting room 3, all of which are fixed to the hardened on-site ground. The annealing furnace 1 is used for stress relief treatment of extra-large equipment, the sandblasting room 3 is used for removing oxide scale and rust from the equipment surface, and the power supply area 2 provides power support for the heating system of the annealing furnace 1, the power system of the sandblasting room 3, and the sliding system of the top cover. These three components form an integrated layout for processing, power supply, and processing, eliminating the need for cross-regional equipment transfer and significantly shortening the process connection time.

[0024] The annealing furnace 1 is equipped with an annealing furnace top cover 4, and the sandblasting room 3 is equipped with a sandblasting room top cover 5. Both top covers are welded from high-strength steel structures and are lined with sealing cotton suitable for the temperature requirements of the corresponding process. The area directly above the power supply area 2 is a top cover storage area, which is used to temporarily store the annealing furnace top cover 4 or the sandblasting room top cover 5 when not in operation, so as to avoid the top cover occupying additional working space.

[0025] Furthermore, the sliding module is used to realize the horizontal sliding of the annealing furnace top cover 4 and the sandblasting chamber top cover 5, so as to control the opening and closing of the top of the annealing furnace 1 or the sandblasting chamber 3. Its specific structure is as follows: Two sets of first support frames are symmetrically arranged on both sides of the annealing furnace 1, the power supply area 2, and the sandblasting room 3. Each set of first support frames consists of multiple first columns 6 adapted to the load, and the spacing between adjacent first columns 6 is set according to the structural stability requirements. The tops of all first columns 6 on the same side are fixedly connected to the top cover slide rail 7 by bolts. The slide rail is made of high-strength steel and the surface is hardened to improve wear resistance.

[0026] A set of sliding components is installed on both sides below the annealing furnace top cover 4 and the sandblasting room top cover 5. Each set of sliding components includes two starting wheel boxes 8 located at both ends of the top cover and two driven wheel boxes 9 located between the two starting wheel boxes 8. The starting wheel box 8 has a built-in drive motor and gearbox, and the drive wheel set slides along the top cover slide rail 7. The driven wheel box 9 only has wheel sets, which move synchronously with the starting wheel box 8. The fit clearance between the wheel set and the top cover slide rail 7 is controlled within a range to ensure smooth sliding.

[0027] The starting wheel box 8 and the driven wheel box 9 of the same set of sliding components are fixed to the I-beam 10 by bolts. The top of the I-beam 10 and the bottom of the top cover are fixed by welding to form a rigid connection structure of wheel box, I-beam 10 and top cover, so as to avoid local stress concentration when the top cover slides.

[0028] Both the starting wheel box 8 and the driven wheel box 9 have hydraulic cylinders 11 vertically mounted on their tops. The piston end of the hydraulic cylinder 11 is fixedly connected to the bottom of the I-beam 10 via a flange. When the top cover needs to be precisely sealed to the top of the annealing furnace 1 / sandblasting room 3, or when the slide rail is slightly worn and the gap increases, the height of the top cover can be adjusted by extending and retracting the hydraulic cylinder 11 to ensure that the sealing gap between the top cover and the furnace / room body is controlled within a reasonable range, thus ensuring the heat preservation effect during annealing and preventing dust from overflowing during sandblasting.

[0029] Furthermore, two sets of second support frames are evenly spaced between the two sets of first support frames. Each set of second support frames consists of multiple second columns 12 adapted to the load of the annealing furnace 1. The support space formed by the first support frames and the second support frames is used to house the annealing furnace 1. The furnace sidewall of the annealing furnace 1 is fixed to the second columns 12, forming a multi-directional support structure to prevent the sidewall of the annealing furnace 1 from deforming due to thermal expansion under high-temperature operation.

[0030] Furthermore, a first top platform 15 is welded and fixed to the top outer side of the first support frame. The width and steel plate thickness of the first top platform 15 meet the requirements for maintenance operation and load bearing, and are used by operators to inspect the top cover slide rail 7 and sliding components. A second top platform 16 is welded and fixed to the top of the second support frame, and is used to inspect the heating elements and temperature sensors in the annealing furnace 1. Both platforms are equipped with anti-slip steps and safety warning signs to ensure the safety of high-altitude operations.

[0031] Furthermore, each of the first column 6 and the second column 12 is provided with a stepped independent foundation 13 between itself and the ground. The foundation is constructed with three layers of concrete and contains an anchor bolt structure adapted to the load. This stepped foundation can withstand the vertical and horizontal loads transmitted by the columns, effectively preventing foundation settlement.

[0032] Furthermore, a gantry crane is installed directly above the annealing furnace top cover 4 and the sandblasting room top cover 5, along the structural axis, serving as a hoisting module 14. The gantry crane's track is laid on the outside of the first top platform, enabling movement along the structural axis. The gantry crane is used to move extra-large equipment.

[0033] Furthermore, a box-type transformer adapted to the total power demand is installed in power supply area 2 to supply power to the heating system of annealing furnace 1, the power system of sandblasting room 3, and the sliding components. The power supply cables are armored cables with protective performance, laid along the cable tray inside the first column 6 to avoid high temperature and mechanical damage; the control system adopts PLC, integrating top cover sliding control, temperature control, sandblasting pressure control, and gantry crane linkage control to realize fully automated operation and reduce manual intervention.

[0034] The working process of this device Equipment entry and annealing operation: After the gantry crane lifts the extra-large equipment into the annealing furnace 1, the PLC controls the top cover 4 of the annealing furnace to slide along the top cover slide rail 7 from the storage area to above the annealing furnace 1. The oil cylinder 11 adjusts the height of the top cover to achieve sealing. The heating system of the annealing furnace 1 is started, and the temperature is raised and maintained according to the process requirements. After stress relief is completed, the temperature is lowered to below the safe temperature.

[0035] Top cover switching and equipment transfer: After annealing, the top cover 4 of the annealing furnace is slid to the power supply area 2 for storage. The equipment is reconnected and lifted by the gantry crane to the top of the sandblasting room 3. Then the top cover 5 of the sandblasting room is slid to the top of the power supply area 2 for storage, thereby opening the sandblasting room 3, so that the gantry crane can put the equipment into the sandblasting room 3 without the need for external equipment transfer.

[0036] Sandblasting operation and top cover reset: The top cover 5 of the sandblasting room slides back to above the sandblasting room 3 and is sealed. The sandblasting pump is started to sandblast the surface of the equipment. After the treatment is completed, the top cover 5 of the sandblasting room slides to the storage area, and the gantry crane lifts the equipment out, completing the entire process.

[0037] This device, through its integrated layout, sliding top cover, multi-directional support frame, and integrated control, effectively solves the problems of slow process connection, cumbersome operation, and poor stability in the on-site fabrication and installation of extra-large equipment. It significantly improves work efficiency, reduces equipment failure rate, meets the requirements of efficient, safe, and stable on-site fabrication and installation, and can flexibly adjust the structural size and configuration according to the specifications and parameters of different extra-large equipment.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
