Description

Technical Field

[0001] This utility model relates to the technical field of centrifuge maintenance devices, specifically a centrifuge maintenance device for pipe pile production. Background Technology

[0002] In the production of concrete pipe piles, centrifuges are crucial molding equipment, using high-speed rotation to evenly distribute and compact concrete within the mold. Centrifuges operate under high-speed, heavy-load conditions for extended periods, making bearings, as core rotating components, highly susceptible to wear, jamming, and other malfunctions. Currently, pipe pile manufacturers commonly use traditional bearing pullers for bearing disassembly and maintenance. These pullers mainly consist of a three-jaw hook, a threaded jack, and a support structure. When centrifuge bearings need replacement, maintenance personnel must operate within the confined space inside the centrifuge. Existing pullers typically only have a single hexagonal head or a fixed handle at the top of the threaded jack, which has certain shortcomings and needs improvement.

[0003] In the present technology, the bearing puller used for centrifuge maintenance has a traditional hexagonal head design that requires the use of a wrench, which is difficult to operate in the narrow space inside the centrifuge. The fixed handle is not compatible with hydraulic tools, resulting in low disassembly efficiency and inconvenient tool switching. When it is necessary to switch from manual operation to tool operation, the entire puller must be replaced or an adapter kit must be used, which wastes time and increases tool management costs. Utility Model Content

[0004] The purpose of this utility model is to provide a centrifuge maintenance device for pipe pile production, which solves the problem of inconvenient tool switching by folding the handle through the setting of a crossbar and a damping shaft.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a centrifuge maintenance device for pipe pile production, including a bearing puller body, a crossbar and a handle. A circular sleeve is installed on the top of the bearing puller body, and an installation groove is opened in the circular sleeve. A circular block is fitted in the installation groove, and a hexagonal head is installed on the top of the circular block. A through hole for fitting the crossbar is opened in the installation groove. Extension blocks are connected to both ends of the crossbar. Fixing holes are opened on the extension blocks, and damping shafts are fitted in the fixing holes. A through hole is opened at the end of the handle, and both ends of the damping shaft fit into the through hole.

[0007] Furthermore, a pre-drilled groove is provided at the end of the handle, which is connected to the through hole, and the extension block is located in the pre-drilled groove.

[0008] Furthermore, there are two handles, located on either side of the circular sleeve.

[0009] Furthermore, both ends of the crossbar are provided with limiting components. The outer surface of the limiting component contacts the outer surface of the circular sleeve. The limiting component has a first half-ring, a second half-ring, and a screw. The tops of the first half-ring and the second half-ring are hinged. The bottoms of the first half-ring and the second half-ring are respectively equipped with a first rectangular block and a second rectangular block. The first rectangular block has a light hole, and the second rectangular block has a threaded hole. The screw passes through the light hole and is threaded into the threaded hole.

[0010] Furthermore, both the inner rings of the first and second half-rings are equipped with arc-shaped strips, which cooperate to form a round strip, and the end of the crossbar is provided with a limiting ring groove that matches the round strip.

[0011] Furthermore, the bearing puller body has a threaded push rod, and a sleeve is installed at the top of the threaded push rod.

[0012] This utility model has the following beneficial effects:

[0013] This invention features a folding handle via a crossbar and a damping pivot. A switchable hexagonal head / handle structure is provided at the top of the threaded rod, allowing the handle to be folded and hidden. This design enables the device to be used in confined spaces for manual operation while remaining compatible with standard hexagonal wrenches or tools, significantly improving the space adaptability for centrifuge bearing maintenance. When the folding handle is unfolded, it allows for rapid manual rotation, saving tool switching time. Furthermore, folding does not affect the use of the hexagonal head and tools, thus improving operational efficiency.

[0014] This utility model uses a limiting component to fix the crossbar and the round block. When the hexagonal head or handle is worn or damaged during use, the detachable installation design allows maintenance personnel to quickly and easily remove the damaged parts from the threaded top rod for individual repair or replacement. Compared with traditional bearing pullers with fixed interfaces, it eliminates the need for complex disassembly or return to the factory for repair, shortening maintenance time and reducing maintenance costs.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a centrifuge maintenance device for pipe pile production, including a bearing puller body 1, a crossbar 5, and a handle 6. The end of the handle 6 has a pre-reserved groove 601, which communicates with a through hole 602. An extension block 7 is located within the pre-reserved groove 601. There are two handles 6, located on opposite sides of a circular sleeve 2. The bearing puller body 1 is existing technology for the maintenance of centrifuges used in pipe pile production, and will not be described in detail here. The bearing puller body 1 has a threaded push rod 101. The sleeve 2 is installed at the top of the threaded top rod 101. The top of the bearing puller body 1 is equipped with the sleeve 2. The sleeve 2 has an installation groove 201. The installation groove 201 is fitted with a round block 3. The top of the round block 3 is equipped with a hexagonal head 4. The installation groove 201 has a through hole 301 for fitting the crossbar 5. Both ends of the crossbar 5 are connected to extension blocks 7. The extension blocks 7 have fixing holes. The fixing holes are fitted with damping shafts 8. The end of the handle 6 has a through hole 602. Both ends of the damping shaft 8 fit into the through hole 602.

[0024] During the overhaul of the centrifuge used in the production of pipe piles, the damaged bearing is disassembled using the bearing puller body 1. Depending on the usage scenario, the hexagonal head 4 and handle 6 are switched. In a confined space, the two handles 6 are rotated so that they rotate along the damping shaft 8 through the through hole 602 to a vertical position, folding the handles 6. The damping shaft 8 is used to maintain the position of the handles 6. At this time, the hexagonal head 4 is rotated using a tool to rotate the threaded push rod 101 of the bearing puller body 1. If manual operation is required, the handle 6 is rotated so that it is horizontal with the crossbar 5, and then the threaded push rod 101 can be rotated using the handle 6.

[0025] Both ends of the crossbar 5 are provided with limiting members 9. The outer surface of the limiting member 9 contacts the outer surface of the sleeve 2. The limiting member 9 has a first half ring 901, a second half ring 902 and a screw 906. The tops of the first half ring 901 and the second half ring 902 are hinged. The bottoms of the first half ring 901 and the second half ring 902 are respectively equipped with a first rectangular block 904 and a second rectangular block 905. The first rectangular block 904 has a light hole, and the second rectangular block 905 has a threaded hole. The screw 906 passes through the light hole and is threaded in the threaded hole. The inner rings of the first half ring 901 and the second half ring 902 are both equipped with arc-shaped strips 903. The two arc-shaped strips 903 cooperate to form a round strip. The end of the crossbar 5 is provided with a limiting ring groove 501 that cooperates with the round strip.

[0026] When the hexagonal head 4 and handle 6 become damaged or worn during use, rotating the screw 906 will cause its end to move out of the threaded hole of the second rectangular block 905, releasing the limiting position on the second rectangular block 905. Then, rotating the first half-ring 901 and the second half-ring 902 will remove the limiting member 9 from the crossbar 5. At this point, pulling the handle 6 horizontally will move the crossbar 5 out of the mounting slot 201. Finally, pulling the hexagonal head 4 upwards will remove the round block 3 from the mounting slot 201, allowing for the repair of the hexagonal head 4 or handle 6. Replace the block 3 and install it into the mounting slot 201. Then move the crossbar 5 laterally so that the handle 6 passes through the mounting slot 201 until both ends of the crossbar 5 are located on both sides of the sleeve 2. Then put the limiting piece 9 on both ends of the crossbar 5 so that the arc strip 903 of the inner ring of the first half ring 901 and the second half ring 902 fits into the limiting ring groove 501. Tighten the screw 906 to fix the second rectangular block 905. This completes the fixing of the crossbar 5 and the block 3, so that the handle 6 and the hexagonal head 4 can be used.
