Description

Technical Field

[0001] This utility model relates to the field of centrifugal motion sound insulation technology, specifically a sound insulation and protection device for the centrifugal motion of a pipe pile mold. Background Technology

[0002] After concrete is injected into the pipe pile mold and it is tightened, the pipe pile mold needs to be placed on a centrifuge to make the pipe pile mold undergo centrifugal motion. The general structure of the centrifuge includes a support, an active running wheel, a passive running wheel, and a drive device. The active running wheel and the passive running wheel are respectively installed on the support. The drive device is connected to the active running wheel and drives the active running wheel, so that the pipe pile mold supported on the active running wheel and the passive running wheel will undergo centrifugal motion under the action of friction.

[0003] However, most existing pipe pile molds generate noise exceeding 100 decibels during centrifugal motion, which can affect the surrounding working environment. In particular, long-term exposure to noise can damage the eardrums of workers operating around the centrifuge, affecting their physical and mental health.

[0004] Therefore, this utility model provides a sound insulation and protection device for the centrifugal motion of pipe pile molds to solve the above problems. Utility Model Content

[0005] This utility model provides a sound insulation and protection device for the centrifugal movement of pipe pile molds, aiming to solve the problem mentioned in the background art that the noise generated by most pipe pile molds during centrifugal movement can cause eardrum damage to workers around the centrifuge.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sound insulation and protection device for the centrifugal movement of a pipe pile mold, comprising a centrifuge body, a connecting block rotatably connected to the outer wall of the centrifuge body, a protective cover for surrounding the centrifuge body fixedly connected to the outer wall of the connecting block, a connecting frame slidably connected inside the connecting block, a through hole for the connecting frame to slide inside the connecting block, a bidirectional threaded rod rotatably connected to the inner wall of the centrifuge body, a threaded sleeve threadedly connected to the outer surface of the bidirectional threaded rod, and the outer surface of the threaded sleeve fixedly connected to the outer wall of the connecting frame.

[0007] As a preferred technical solution of this application, a rotating rod is rotatably connected to the outer wall of the centrifuge body, and a motor for driving the rotating rod to rotate is provided on the outer wall of the centrifuge body.

[0008] As a preferred technical solution of this application, a rotating block is fixedly connected to the end of the rotating rod away from the motor, and a support block is rotatably connected to the outer wall of the rotating block.

[0009] As a preferred technical solution of this application, the outer wall of the support block is fixedly connected with friction pins, and the outer surface of the rotating rod is connected to the outer surface of the bidirectional threaded rod by a transmission belt.

[0010] As a preferred technical solution of this application, a telescopic rod is fixedly connected to the outer wall of the connecting frame, and the end of the telescopic rod away from the connecting frame is fixedly connected to the inner wall of the centrifuge body.

[0011] As a preferred technical solution of this application, the bottom of the centrifuge body is provided with a first slot for the connecting frame to move, and the top of the centrifuge body is provided with a second slot for the transmission belt to rotate.

[0012] Beneficial effects

[0013] This invention, through the arrangement of a rotating rod, a rotating block, a support block, a transmission belt, a bidirectional threaded rod, a threaded sleeve, a connecting frame, a connecting block, and a protective cover, allows the rotating rod to rotate when the motor drives it. This rotation causes the rotating block to rotate, and when the rotating block reaches a certain angle, the support block, which meshes with the rotating block, can adhere to the ground. The support block, when in contact with the rotating block, can self-adjust, providing friction to reduce vibration during centrifuge operation and thus reduce noise. Simultaneously, the transmission belt, which meshes with the rotating rod, drives the bidirectional threaded rod to rotate synchronously. When the bidirectional threaded rod rotates, the two threaded sleeves that are threadedly engaged with the bidirectional threaded rod can drive the connecting frame to move away from each other. When the connecting frame moves within the through hole, it can squeeze the connecting block to tilt at an angle, causing the two connecting blocks to drive the protective cover to merge and surround the centrifuge body, reducing the transmission of noise. Thus, this device can greatly reduce the noise of the centrifuge body during centrifugation, preventing excessive noise from affecting the surrounding working environment and avoiding long-term noise interference that could damage the eardrums of workers around the centrifuge body, ensuring that the physical and mental health of the workers is not affected.

[0021] 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.

[0022] This utility model provides a sound insulation and protection device for the centrifugal motion of pipe pile molds, such as Figure 1-5 As shown, the sound insulation device includes a centrifuge body 1, a connecting block 2 rotatably connected to the outer wall of the centrifuge body 1, a protective cover 3 for surrounding the centrifuge body 1 fixedly connected to the outer wall of the connecting block 2, a connecting frame 4 slidably connected inside the connecting block 2, a through hole 5 for the connecting frame 4 to slide inside the connecting block 2, a bidirectional threaded rod 6 rotatably connected to the inner wall of the centrifuge body 1, a threaded sleeve 7 threadedly connected to the outer surface of the bidirectional threaded rod 6, and the outer surface of the threaded sleeve 7 fixedly connected to the outer wall of the connecting frame 4.

[0023] When the bidirectional threaded rod 6 rotates, the two threaded sleeves 7 that are threadedly engaged with the bidirectional threaded rod 6 can drive the connecting frame 4 to move away from each other. During the process of the two connecting frames 4 moving away from each other, they can move within the through hole 5, causing the two connecting frames 4 to squeeze the connecting block 2 to tilt at an angle. When the two connecting blocks 2 drive the protective cover 3 to tilt at a certain angle, the two protective covers 3 can be in a combined state, so as to surround the moving area above the centrifuge body 1, thereby blocking the transmission of noise, reducing the impact of noise on the surrounding staff, and effectively preventing damage to the staff's eardrums.

[0024] A rotating rod 8 is rotatably connected to the outer wall of the centrifuge body 1. A motor 9 for driving the rotating rod 8 to rotate is provided on the outer wall of the centrifuge body 1. A rotating block 10 is fixedly connected to the end of the rotating rod 8 away from the motor 9. A support block 11 is rotatably connected to the outer wall of the rotating block 10. A friction pin 12 is fixedly connected to the outer wall of the support block 11. A transmission belt 13 is drivingly connected to the outer surface of the rotating rod 8 and the outer surface of the bidirectional threaded rod 6.

[0025] The motor 9 enables the rotating rod 8 to rotate. When the motor 9 is running, the output shaft drives the rotating rod 8 to rotate, which in turn drives the rotating block 10 to rotate. When the rotating block 10 is about to contact the ground, the support block 11, which rotates with it, will also contact the ground. At the same time, the support block 11 can automatically adjust itself when it contacts the ground due to the rotational engagement with the rotating block 10. Furthermore, the several friction pins 12 can further improve stability when they contact the ground, thus ensuring good stability when the support block 11 contacts the ground. This effectively reduces the noise generated by vibration during the operation of the centrifuge body 1. When the rotating rod 8 rotates, it drives the transmission belt 13, which in turn drives the bidirectional threaded rod 6 to rotate synchronously. This allows the support block 11 and the protective cover 3 to simultaneously provide sound insulation protection for the centrifuge body 1. The operation is simple, and both can be used simultaneously to provide sound insulation protection for the centrifuge body 1. The operation is also simple when sound insulation is not required.

[0026] A telescopic rod 14 is fixedly connected to the outer wall of the connecting frame 4, and the end of the telescopic rod 14 away from the connecting frame 4 is fixedly connected to the inner wall of the centrifuge body 1.

[0027] The telescopic rod 14 provides a limiting point for the threaded sleeve 7, and its telescopic characteristics also allow the threaded sleeve 7 to move. This ensures that the threaded sleeve 7 can move smoothly when the bidirectional threaded rod 6 rotates, preventing the threaded sleeve 7 from rotating synchronously with the bidirectional threaded rod 6 when it lacks a limiting point. This ensures that the threaded sleeve 7 can drive the connecting frame 4 to move smoothly, causing the connecting frame 4 to squeeze the connecting block 2 and tilt the protective cover 3 at an angle.

[0028] The centrifuge body 1 has a first slot 15 at the bottom for the connecting frame 4 to move, and a second slot 16 at the top for the drive belt 13 to rotate.

[0029] The first slot 15 provides space for the connecting frame 4 to move, preventing the connecting frame 4 from being blocked by the centrifuge body 1 and thus allowing the connecting frame 4 to move smoothly and push the connecting block 2. The second slot 16 provides space for the transmission belt 13 to rotate, preventing the transmission belt 13 from being blocked by the centrifuge body 1 and thus allowing the rotating rod 8 and the bidirectional threaded rod 6 to rotate synchronously, so that the support block 11 and the protective cover 3 can simultaneously provide sound insulation and protection for the centrifuge body 1.

[0030] Working principle:

[0031] When sound insulation protection is required for the centrifuge body 1 in use, the motor 9 is started first, causing the output shaft of the motor 9 to drive the rotating rod 8 to rotate. When the rotating rod 8 drives the rotating block 10 to rotate to a certain angle, the support block 11, which rotates with the rotating block 10, can make contact with the ground. The rotational engagement with the rotating block 10 allows for adaptive adjustment, ensuring a more secure contact and support between the support block 11 and the ground. This reduces the vibration generated during the operation of the centrifuge body 1, thereby reducing noise. Furthermore, the rotating rod 8, through the transmission belt 13, drives the bidirectional threaded rod 6 to rotate synchronously. When the bidirectional threaded rod 6 rotates, the two threaded sleeves 7, which are threaded with the bidirectional threaded rod 6, can drive the connecting frame 4 to move away from each other. When both connecting frames 4 move within the through hole 5, they can respectively push the connecting block 2 to tilt at an angle, causing the two connecting blocks 2 to drive the protective cover 3 to merge and surround the top of the centrifuge body 1. This significantly reduces noise transmission during the centrifugal motion of the centrifuge body 1.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
