Description

Technical Field

[0001] This utility model belongs to the field of marine ventilation technology, and specifically relates to a maintenance device for an upward-exhausting axial flow fan. Background Technology

[0002] The cargo pump room on board requires frequent personnel access, and ventilation is necessary before personnel can enter. In addition, according to regulations, the fan in the cargo pump room needs to be equipped with an additional motor. There are also requirements on the distance and height of the installation location of the cargo pump room fan from the front wall of the deck. Ultimately, an upper-exhaust axial flow fan was selected for the cargo pump room, but the inspection and maintenance of this fan faces a major problem. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a maintenance device for an upward-exhausting axial flow fan.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A top-mounted axial flow fan maintenance device includes a motor hoisting assembly and a surrounding fan maintenance platform. The surrounding fan maintenance platform surrounds the outer periphery of the motor, and the motor hoisting assembly is rotatably mounted on one side of the surrounding fan maintenance platform.

[0005] Furthermore, the motor hoisting assembly includes a column, with a running track vertically provided at the upper end of the column, and a traveling toothed track extending along its length on the lower end surface of the running track. A traveling trolley and a hand-operated hoist are movably connected on the traveling toothed track. The lower end of the column is rotatably connected to a column base fixed to the surrounding fan maintenance platform from 0 to 180 degrees.

[0006] Furthermore, a limiting baffle is fixed at each end of one side wall along the length of the running track.

[0007] Furthermore, a limiting plate is fixed on the outer wall of the upper port of the column base, and a flange is fixed on the side wall of the column, with the flange tightly attached to the limiting plate.

[0008] Furthermore, the surrounding wind turbine maintenance platform is annular with an angle of not less than 180°, and protective railings are provided on the upper surface of the surrounding wind turbine maintenance platform.

[0009] Furthermore, the motor is placed inside the housing and is detachably connected to the housing; the inner surface of the ring of the surround-type fan maintenance platform is fixedly connected to the outer wall of the housing; the cross-section of the housing is an arc shape with the same curvature as the surround-type fan maintenance platform.

[0010] Furthermore, a support plate is connected between the lower end face of the surrounding wind turbine maintenance platform and the side wall of the casing located below it.

[0011] Furthermore, a detachable chain is provided at the entrance of the surrounding wind turbine maintenance platform, and both ends of the detachable chain are connected to the guardrail.

[0012] This utility model's top-discharge axial flow fan maintenance device allows for the direct lifting of the internal motor to an open area for repair when the fan malfunctions or requires maintenance, eliminating the need to call a crane and significantly reducing labor and time costs. A surrounding platform provides a large load capacity, high wind resistance, and ensures safety and reliability. The maintenance platform and fan can be shipped separately, allowing for on-site welding and assembly by the user. The strength meets safety and usage requirements. The top-discharge axial flow fan maintenance device is simple and reliable. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-2 As shown, an upper-displacement axial flow fan maintenance device includes a motor hoisting assembly and a surrounding fan maintenance platform 11. The surrounding fan maintenance platform 11 surrounds the outer periphery of the motor 10, and the motor hoisting assembly is rotatably mounted on one side of the surrounding fan maintenance platform.

[0018] Specifically, the motor hoisting assembly includes a column 3, with a running track 4 vertically arranged at the upper end of the column 3, and a traveling toothed track 5 extending along its length on the lower end surface of the running track 4. A traveling trolley 6 and a hand-operated hoist 7 are movably connected on the traveling toothed track 5. The lower end of the column 3 is rotatably connected to the column base 1 fixed on the surrounding fan maintenance platform 11 within the range of 0 to 180°.

[0019] By pulling the manual hoist 7, the internal motor 10 can be directly lifted and moved to the open maintenance platform 11 for maintenance when the motor 10 fails or needs repair.

[0020] Furthermore, in order to prevent the chain hoist 7 from falling off during operation, a limiting baffle 8 is fixed at both ends of one side wall along the length of the running track 4.

[0021] Furthermore, a limiting plate 2 is fixed on the outer wall of the upper port of the column base 1, and a flange 31 is fixed on the side wall of the column 3, with the flange 31 and the limiting plate 2 tightly attached to each other vertically.

[0022] This configuration limits the relative rotation or excessive relative translation between the column base 1 and the flange in the horizontal plane.

[0023] Furthermore, the surrounding wind turbine maintenance platform 11 is annular with an angle of not less than 180°. Since this maintenance platform is relatively high, a protective railing 12 is provided on the upper surface of the surrounding wind turbine maintenance platform 11.

[0024] Furthermore, the motor 10 is placed inside the housing 9 and is detachably connected to the housing 9; the inner surface of the ring of the surrounding fan maintenance platform 11 is fixedly connected to the outer wall of the housing 9; the cross-section of the housing 9 is an arc shape with the same curvature as the surrounding fan maintenance platform 11.

[0025] Furthermore, a support plate 13 is connected between the lower end face of the surrounding fan maintenance platform 11 and the side wall of the casing 9 located below it, which improves the wind resistance coefficient and ensures safety and reliability.

[0026] Furthermore, a detachable chain 14 is provided at the entrance of the surrounding wind turbine maintenance platform 11. The two ends of the detachable chain 14 are connected to the two sides of the entrance of the guardrail 12. This facilitates personnel to enter and exit to observe the condition of the wind turbine and perform maintenance. When personnel are not going in, the detachable chain 14 can be hung up to prevent personnel from entering at will.

[0027] Those skilled in the art should understand that the above description is merely a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
