Description

Technical Field

[0001] This utility model relates to the field of pipe fitting transmission technology, specifically a pipe fitting turning mechanism with optimized space occupancy. Background Technology

[0002] In existing pipe-feature turning mechanisms, a turning arm typically extends below the pipe-feature conveyor rollers, and then a drive unit drives the turning arm to flip, thereby lifting the pipes on the conveyor rollers. The turning arm then flips again to tilt and place the pipes onto the pipe-feature rack. However, the turning mechanism in the above-mentioned technical solution occupies a large amount of space on the side of the pipe-feature conveyor rollers, making it impossible to install other components or mechanisms on the side of the conveyor rollers, resulting in low space utilization. Furthermore, the rolling of the pipes during the turning and transfer process generates significant noise.

[0003] The patent, authorized by CN211467394U and entitled "Utility Model of Integrated Pipe Fitting Turning and Storage Device," discloses an integrated pipe fitting turning and storage device. This device includes a height adjustment device with opposing components. A corner bracket is mounted on top of the height adjustment device, and a fixed guide frame is mounted on top of the corner bracket. The corner bracket and the fixed guide frame are connected by several bolts. A cylinder is positioned opposite to the height adjustment device on its inner side. The bottom of the cylinder is connected to the height adjustment device by a lower cylinder seat, and a movable guide frame is mounted on top of the cylinder. An upper cylinder seat is positioned between the cylinder and the movable guide frame. The movable guide frame and the fixed guide frame are connected by several hinges. A discharge rack is also provided inside the height adjustment device. Several rollers are respectively mounted on the fixed guide frame and the movable guide frame. However, when turning pipe fittings, the drive mechanism of this utility model occupies the side of the pipe fitting conveyor roller, making it impossible to place other equipment structures, resulting in low space utilization. Furthermore, the pipe fittings generate significant noise when falling into the storage rack. Utility Model Content

[0004] In order to solve the technical problems of low space utilization and high noise in existing pipe turning mechanisms, this utility model proposes a pipe turning mechanism.

[0005] The pipe fitting turning mechanism includes a pipe fitting rack, a synchronous shaft, and a plurality of turning arms. The synchronous shaft is mounted on the pipe fitting rack. One end of each of the plurality of turning arms is limited and rotates synchronously with the synchronous shaft. The turning arms can rotate 360° around the synchronous shaft and pass through the gaps in the pipe fitting rack during rotation. The mechanism also includes pipe fitting support structures of the same number as the turning arms. Each pipe fitting support structure is correspondingly mounted on the other end of the turning arm, and the top surface of the pipe fitting support structure always remains horizontal and upward during the rotation of the turning arm around the synchronous shaft.

[0006] The aforementioned pipe fitting turning mechanism includes a pipe fitting support structure comprising a base and a support block. The base is rotatably connected to one end of the turning arm, and the support block is fixedly installed at the top of the base, with the top of the support block always remaining horizontal and facing upward.

[0007] The aforementioned pipe tipping mechanism also includes a fixed gear, a moving gear, and a transmission chain. The fixed gear is fixedly mounted on a synchronous shaft and can rotate coaxially with the tipping arm. The moving gear is located at one end of the tipping arm and is coaxially connected to the base. The fixed gear and the moving gear are connected by a transmission chain.

[0008] The aforementioned pipe tipping mechanism has tipping arms spaced apart on a synchronous shaft, with the gap between the tipping arms determined by the length of the pipe.

[0009] The beneficial effects of this utility model include: By setting the tipping arm to be able to rotate 360° and pass through the pipe fitting rack, and by setting a pipe fitting support structure that can keep the top surface horizontal and upward during the rotation of the tipping arm, the tipping arm can work at various angles. The space on the side of the pipe fitting conveyor roller will not be occupied by the tipping mechanism and can be used for other equipment. Furthermore, when transporting pipe fittings, the pipe fitting support structure can place the pipe fittings directly on the pipe fitting rack, thereby avoiding the pipe fittings falling onto the pipe fitting rack and generating noise. This solves the technical problems of low space utilization and high noise in the existing pipe fitting tipping mechanism. Attached Figure Description

[0014] The present invention will now be described in conjunction with the accompanying drawings.

[0015] like Figures 1-2 The diagram shows the pipe fitting turning mechanism of this utility model, including a pipe fitting rack 1, a synchronous shaft 2, and a plurality of turning arms 3. A space is left between the pipe fitting rack 1 and the pipe fitting conveyor rollers for installing other equipment. The size of this reserved space is adjusted according to the volume of different equipment, and turning arms 3 of appropriate length are used, for example... Figure 1The material distribution mechanism 7 shown can transfer pipes to a preset pipe rack 1 according to the length of the pipes. The synchronous shaft 2 is set on the pipe rack 1. One end of a plurality of turning arms 3 is limited and cooperates with the synchronous shaft 2 and rotates synchronously with it. The turning arms 3 can rotate 360° around the synchronous shaft 2 and pass through the gaps in the pipe rack when rotating. It also includes a pipe support structure 4 with the same number of turning arms 3. The pipe support structure 4 is set one-to-one with the other end of the turning arms 3. During the rotation of the turning arms 3 around the synchronous shaft 2, the top surface of the pipe support structure 4 always remains horizontal and upward. When the turning mechanism turns the pipes, since the turning arms 3 can pass through the gaps in the pipe rack 1 and the top surface of the pipe support structure 4 always remains horizontal and upward, the pipes can be directly placed on the pipe rack 1.

[0016] Furthermore, the pipe fitting support structure 4 includes a base 41 and a support block 42. The base 41 is rotatably connected to one end of the tipping arm 3. The support block 42 is fixedly installed on the top of the base 41. The top of the support block 42 always remains horizontal and upward, which further limits the pipe fitting support structure 4. When the pipe fitting is tipped, the support block 42 limits it to prevent the pipe fitting from rolling off during tipping.

[0017] Furthermore, it also includes a fixed gear 5, a moving gear 6, and a transmission chain. In this embodiment, the fixed gear 5 and the moving gear 6 have the same size and number of teeth. The fixed gear 5 is fixedly mounted on the synchronous shaft 2 and can rotate coaxially with the turning arm. The moving gear 6 is mounted on one end of the turning arm 3 and is coaxially fixedly connected to the base 41. The fixed gear 5 and the moving gear 6 are connected by a transmission chain (not shown in the figure). When the synchronous shaft 2 rotates, the turning arm 3 and the fixed gear 5 rotate synchronously with the synchronous shaft 2. The moving gear 6 is driven by the transmission chain to rotate synchronously with the fixed gear 5, and further drives the base 41 and the support block 42 on the base 41 to rotate relative to the turning arm 3, so that the top surface of the support block 42 always remains horizontal and upward.

[0018] Furthermore, the tipping arms 3 are spaced apart on the synchronous shaft 2, and the gap between the tipping arms 3 is determined according to the length of the pipe fitting, such as... Figure 3 As shown, the gap between the tipping arms 3 can be adjusted according to the length of the pipe fitting, thereby reducing the number of tipping arms 3 required while tipping pipe fittings of different lengths, thus avoiding structural redundancy.

[0019] In use, the base 41 and the support block 42 of the present invention described in the above embodiment are driven by the moving gear 6 and the transmission chain, and rotate clockwise synchronously with the fixed gear 5 and the synchronous shaft 2. This causes the turning arm 3 and the pipe support structure 4 to lift the pipes on the pipe conveying rollers from the gap between the two connected roller structures in the left pipe conveying rollers and rotate them to the right pipe rack 1. When the pipe support structure 4 rotates into the gap of the pipe rack 1, the pipes can be placed on the crossbeam of the pipe rack 1. During the above pipe turning process, a pre-set support is provided. The top surface of the support block 42 is horizontally upward. The fixed gear 5 rotates with the synchronous shaft 2, and the moving gear 6 is driven by the transmission chain to rotate synchronously with the fixed gear 5. This ensures that the top surface of the support block 42 remains horizontally upward while rotating with the flipping arm 3. When not flipping, the flipping arm 3 and the pipe support structure 4 can rotate into the gap of the pipe rack 1 for standby. The space between the pipe rack 1 and the pipe conveyor roller is not occupied by the flipping mechanism, which can provide installation or travel space for other mechanisms such as the material distribution mechanism. In this embodiment, the synchronous shaft 2 is driven by a motor.

[0020] Compared with the prior art, the pipe turning mechanism provided by this utility model, while realizing pipe turning, also sets the pipe support structure on a plurality of turning arms, so that the turning arms and the pipe support structure can pass through the gaps between the pipe conveyor rollers and the pipe rack. At the same time, through the structure of fixed gears, moving gears and transmission chains, the top surface of the pipe support structure can always remain horizontal and upward during the rotation of the turning arms. Through the above technical solution, the turning arms can work or standby at various angles, so that the space on the side of the pipe conveyor rollers will not be occupied by the turning mechanism and can be used for other equipment. Furthermore, when transporting pipes, the pipe support structure can place the pipes directly on the pipe rack, avoiding the pipes falling onto the pipe rack and generating noise. This solves the technical problems of low space utilization and high noise in the prior art pipe turning mechanism.
