Description

Technical Field

[0001] This invention relates to the field of suspended conveying technology, specifically to a suspended conveying system that facilitates the assembly of axial flow pump blades. Background Technology

[0002] Axial flow pumps are pumps that use the force generated by the blades of a rotating impeller to transport liquid along the axial direction. There are several types, including vertical, horizontal, inclined, and through-flow pumps. When installing an axial flow pump, the pump and impeller need to be combined and installed.

[0003] When installing axial flow pump blades, they typically need to be transported to the pump's location first. This requires a suspended conveyor system. Suspended conveyors (conveyor machinery) are commonly used continuous conveying equipment, widely applied for the continuous transport of various packaged goods and bulk materials in containers or bags within a factory. They can also be used in production lines across various industrial sectors to transport workpieces between processes, completing various technological steps and achieving integrated mechanization of conveying and processing operations. Their structure mainly consists of a traction chain, carriage, lifting device, overhead track, drive unit, tensioning device, and various safety devices.

[0004] When existing axial flow pump blades are suspended and transported, the blades are prone to swaying and friction with the suspension structure, resulting in wear. Furthermore, the transport efficiency is low, and the suspension mechanism is difficult to adapt to blades of different sizes for transport. Therefore, it does not meet the current requirements. To address this, we propose a suspension transport system that facilitates the assembly of axial flow pump blades. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention utilizes the cooperation of a driving gear and a driven half-gear ring to enable the device to rotate via a reduction motor during use. The driving gear rotates, which in turn drives the driven half-gear ring to rotate. When it is necessary to transport or lower axial flow pump blades, the driven half-gear ring can rotate and move inside the axial flow pump blade. When the driven half-gear ring enters the interior of the axial flow pump blade, it supports the axial flow pump blade, thereby transporting it. When the driven half-gear ring leaves the interior of the axial flow pump blade, it releases the support for the axial flow pump blade, allowing the axial flow pump blade to be lowered from the device for installation. Simultaneously, the device can transport axial flow pump blades of different sizes.

[0019] 2. This invention, through the cooperation of the suspension structure and the support structure, allows the driven half-tooth ring to enter the interior of the axial flow pump blade during use. A fixed pusher can then push the semi-circular block, causing it to carry the supporting arc tube into the interior of the axial flow pump blade. At this time, the telescopic inner rod is ejected by the elastic force of the compression spring and comes into contact with the inner wall of the axial flow pump blade. This prevents the inner wall of the axial flow pump blade from contacting the surface of the driven half-tooth ring, thus avoiding wear on the axial flow pump blade during rotation. It also keeps the driven half-tooth ring at the center position inside the axial flow pump blade, thereby reducing the weight of the axial flow pump blade through the elastic force of the compression spring and preventing the driven half-tooth ring from breaking due to bearing the weight of the axial flow pump blade.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Please see Figures 1 to 7 The present invention provides an embodiment of a suspended conveying system that facilitates the assembly of axial flow pump blades, including a track module 1, a plurality of material changing modules 2 below the track module 1, a suspension structure 3 on both sides of the material changing module 2, and a support structure 4 on the surface of the suspension structure 3.

[0030] The suspension structure 3 includes a fixed block 301, a connecting plate 302, a reduction motor 303, an arc-shaped fixed plate 304, a drive gear 306, and a driven half-gear ring 307. The fixed blocks 301 are fixedly installed on both sides of the material changing module 2. The connecting plate 302 is fixedly installed on the outer end of the fixed blocks 301. The drive gear 306 is rotatably installed on the inner side of the connecting plate 302. The arc-shaped fixed plate 304 is fixedly installed on the outer end of the connecting plate 302. The driven half-gear ring 307 is slidably installed inside the arc-shaped fixed plate 304. The reduction motor 303 is provided at the top of the connecting plate 302. The output end of the reduction motor 303 is connected to the drive gear 306 through a coupling. The drive gear 306 is meshed with the driven half-gear ring 307.

[0031] Through the cooperation of the driving gear 306 and the driven half-gear ring 307, the device can be used by driving the driving gear 306 to rotate via the reduction motor 303, thereby driving the driven half-gear ring 307 to rotate. When it is necessary to transport or lower the axial flow pump blade 5, the driven half-gear ring 307 can rotate and move inside the axial flow pump blade 5. When the driven half-gear ring 307 enters the interior of the axial flow pump blade 5, it can support the axial flow pump blade 5, thereby transporting the axial flow pump blade 5. When the driven half-gear ring 307 leaves the interior of the axial flow pump blade 5, the support for the axial flow pump blade 5 is released, and the axial flow pump blade 5 can be lowered from the device for installation. At the same time, the device can transport axial flow pump blades 5 of different sizes.

[0032] The suspension structure 3 also includes a rotating groove 305, a T-shaped slide groove 308, a fixed push block 309, a push block sliding groove 310, and a limiting block 311. The outer side of the arc-shaped fixed plate 304 is provided with a rotating groove 305. The driven half-gear ring 307 is slidably inserted into the interior of the rotating groove 305. The inner surface of the driven half-gear ring 307 is provided with a T-shaped slide groove 308. The top and bottom surfaces of the driven half-gear ring 307 are fixedly installed near the support structure 4. The inner wall surface of the rotating groove 305 is provided with two push block sliding grooves 310. The fixed push block 309 is movably inserted into the interior of the push block sliding groove 310. The inside of the rotating groove 305 is fixedly installed on the side near the support structure 4. The limiting block 311 is slidably inserted into the interior of the T-shaped slide groove 308.

[0033] The material changing module 2 includes a sliding seat 201, sliding rods 202, pulleys 203, a rotating table 204, a partition plate 205, and a servo motor 206. The sliding seat 201 is movably installed below the track module 1. Two sliding rods 202 are fixedly installed on the top of the sliding seat 201. Pulleys 203 are rotatably installed on the inner side of each sliding rod 202. The pulleys 203 are movably inserted into the interior of the track module 1. A rotating table 204 is rotatably installed on the bottom of the sliding seat 201. A partition plate 205 is fixedly installed on the bottom of the rotating table 204. The servo motor 206 is installed inside the sliding seat 201. The output end of the servo motor 206 is connected to the top of the rotating table 204 through a coupling.

[0034] By cooperating with the rotating table 204 and the sliding seat 201, the device can drive the rotating table 204 to rotate via the servo motor 206, thereby allowing the axial flow pump blades 5 on both sides to interchange positions, increasing the quantity transported by the device each time, and thus accelerating the installation rate of the axial flow pump blades 5.

[0035] The support structure 4 includes a support arc tube 401, a telescopic outer rod 402, a telescopic inner rod 403, a spring groove 404, a compression spring 405, and a T-shaped slider 406. The top and bottom ends of the support arc tube 401 are fixedly installed with the telescopic outer rod 402. The inside of the telescopic outer rod 402 is provided with a spring groove 404. The inside of the spring groove 404 is slidably installed with the telescopic inner rod 403. The compression spring 405 is movably installed between the inside of the telescopic inner rod 403 and the inside of the spring groove 404. The T-shaped slider 406 is fixedly installed on the inner wall of the support arc tube 401 near the driven half-tooth ring 307.

[0036] With the cooperation of the suspension structure 3 and the support structure 4, when the device is in use, when the driven half-tooth ring 307 enters the interior of the axial flow pump blade 5, the semi-circular block can be pushed by the fixed push block 309, thereby driving the support arc tube 401 into the interior of the axial flow pump blade 5. At this time, the telescopic inner rod 403 will be ejected by the elastic force of the compression spring 405 and will fit against the inner wall of the axial flow pump blade 5, so that the inner wall of the axial flow pump blade 5 will not contact the surface of the driven half-tooth ring 307, thereby avoiding wear on the axial flow pump blade 5 when the driven half-tooth ring 307 rotates, and keeping the driven half-tooth ring 307 in the center position inside the axial flow pump blade 5. Thus, the elastic force of the compression spring 405 reduces the weight of the axial flow pump blade 5, preventing the driven half-tooth ring 307 from breaking due to bearing the weight of the axial flow pump blade 5.

[0037] The axial flow pump blade 5 is located on the surface of the driven half-tooth ring 307. The support structure 4 is movably inserted into the interior of the axial flow pump blade 5. The outer ends of the telescopic inner rod 403 are all in contact with the inner wall surface of the axial flow pump blade 5.

[0038] One end of the compression spring 405 is connected to the inner wall of the spring groove 404, and the other end of the compression spring 405 is connected to the telescopic inner rod 403. The outer end of the telescopic inner rod 403 is provided with a flexible anti-slip pad, and the flexible anti-slip pad is in contact with the inner wall surface of the axial flow pump blade 5.

[0039] Semicircular blocks are fixedly installed on both sides of the supporting arc tube 401. The driven semi-gear ring 307 is movably inserted into the position between the semicircular blocks, and the fixed push block 309 is in contact with the surface of the semicircular blocks.

[0040] The T-shaped slider 406 is inserted into the interior of the T-shaped groove 308, and there are blocking blocks on both sides inside the T-shaped groove 308.

[0041] The bottom of the sliding seat 201 is provided with an annular groove, and the top of the rotating table 204 is fixedly installed with an annular buckle, which is movably engaged into the interior of the annular groove.

[0042] The fixing blocks 301 are all welded to the partition plate 205. The outer side of the connecting plate 302 is provided with a dust cover, and the drive gear 306 is movably inserted into the inside of the dust cover.

[0043] In use, the suspended conveying system that facilitates the assembly of axial flow pump blades first places the axial flow pump blade 5 near the driven half-gear ring 307. Then, the drive gear 306 is driven to rotate by the reduction motor 303, which in turn drives the driven half-gear ring 307 to rotate. When it is necessary to convey or lower the axial flow pump blade 5, the driven half-gear ring 307 can rotate and move inside the axial flow pump blade 5. When the driven half-gear ring 307 enters the interior of the axial flow pump blade 5, it can support the axial flow pump blade 5, thereby conveying the axial flow pump blade 5. When the driven half-gear ring 307 leaves the interior of the axial flow pump blade 5, the support for the axial flow pump blade 5 is released. At this time, the axial flow pump blade 5 can be lowered from the device for installation. At the same time, the device can convey axial flow pump blades 5 of different sizes.

[0044] When the driven half-tooth ring 307 enters the interior of the axial flow pump blade 5, the semi-circular block can be pushed by the fixed push block 309, thereby driving the supporting arc tube 401 into the interior of the axial flow pump blade 5. At this time, the telescopic inner rod 403 will be ejected by the elastic force of the compression spring 405 and will fit against the inner wall of the axial flow pump blade 5, so that the inner wall of the axial flow pump blade 5 will not contact the surface of the driven half-tooth ring 307, thereby avoiding wear on the axial flow pump blade 5 when the driven half-tooth ring 307 rotates, and keeping the driven half-tooth ring 307 in the center position inside the axial flow pump blade 5. Thus, the elastic force of the compression spring 405 reduces the weight of the axial flow pump blade 5, preventing the driven half-tooth ring 307 from breaking due to bearing the weight of the axial flow pump blade 5.

[0045] By cooperating with the rotating table 204 and the sliding seat 201, the device can drive the rotating table 204 to rotate via the servo motor 206, thereby allowing the axial flow pump blades 5 on both sides to interchange positions, increasing the quantity transported by the device each time, and thus accelerating the installation rate of the axial flow pump blades 5.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
