[0002] Vibratory compaction devices used in construction are mechanical equipment that uses vibration to compact ground or backfill soil, aiming to improve soil density, enhance foundation bearing capacity, and reduce settlement. Common types include vibratory rammers and plate vibratory rammers, and they are widely used in various building foundation construction, road construction, dam reinforcement, and other scenarios.
[0003] However, existing vibratory compaction devices used in construction have the following disadvantages: (1) The existing construction vibratory tamping device has a weak vertical tamping function. When the device vibrates, the direction of the vibration cannot be controlled, which may cause too much force to be applied to the ground, thus reducing the vertical tamping effect of the device.
[0004] (2) The existing construction vibration tamping device has a weak vibration damping and noise reduction function. When the existing device is operated, the excessive vibration and noise may cause it to be unsuitable for workers to hold and operate for a long time. Utility Model Content
[0005] The purpose of this utility model is to provide a vibratory tamping device for construction, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibratory tamping device for construction, comprising a tamping assembly and a vibration damping and noise reduction assembly. The tamping assembly consists of a fixed frame, a rotating frame, a rotating rod, a fixed cylinder, a rotating shaft, an eccentric wheel, a transmission belt, a fixed shaft, and a stepping motor. The top of the fixed frame is fixedly connected to the rotating frame, the inner wall of the rotating frame is rotatably connected to the rotating rod, the bottom of the rotating rod is fixedly connected to the fixed cylinder, the inner wall of the fixed cylinder is rotatably connected to the rotating shaft, the two ends of the rotating shaft are fixedly connected to the eccentric wheel, the outer surface of the rotating shaft is provided with a transmission belt at its center, one end of the inner wall of the transmission belt is provided with a fixed shaft, and one end of the fixed shaft is fixedly connected to the stepping motor. The vibration damping and noise reduction assembly consists of a spring, a damper, and an isolation shell fixed to the inner wall of a fixed frame. The inner wall of the spring is provided with a damper, and the top of the fixed frame is fixedly connected to the isolation shell.
[0007] Preferably, a mounting bracket is fixedly connected to one end edge of the fixed frame, and the inner wall of the mounting bracket is fixedly connected to one end of the progress motor. The progress motor is installed inside the fixed frame through the mounting bracket.
[0008] Preferably, the rotating rod has circular slots at the center of both sides, and the inner wall of the circular slots is fixedly connected to one end of the damper, with one end of the damper installed in the circular slots on the rotating rod.
[0009] Preferably, a rotating groove is formed at the center of the outer surface of the fixed cylinder, and the inner wall of the rotating groove is disposed at one end of the outer surface of the transmission belt. The transmission belt is connected to the rotating shaft inside the fixed cylinder through the rotating groove on the fixed cylinder.
[0010] Preferably, the bottom of the fixing frame is provided with a rectangular groove, and a tamping plate is fixedly connected to the inner wall of the rectangular groove. When the eccentric wheel inside the fixing frame rotates and generates vibration, it will drive the tamping plate to press down on the ground.
[0011] Preferably, a fixing groove is provided on the back of the isolation shell, and a handle is fixedly connected to the inner wall of the fixing groove, so that the operator can hold the handle on the isolation shell to control the position of the device for tamping.
[0012] Compared with this device, the beneficial effects of this utility model are: 1. This vibratory compaction device for construction uses a fixed frame, rotating frame, rotating rod, fixed cylinder, rotating shaft, eccentric wheel, transmission belt, fixed shaft, and advance motor. In use, the operator manually starts the device, causing the advance motor to drive the fixed shaft to rotate. The fixed shaft then drives the transmission belt, which in turn drives the rotating shaft inside the fixed cylinder to rotate. This rotating shaft then drives the eccentric wheels at both ends to rotate. The rotation generates centrifugal force (a periodically changing inertial force), resulting in vertical vibration. The rotating rod on the fixed cylinder swings within the rotating frame on the inner wall of the fixed frame. This configuration, with the eccentric wheels rotating at the same high speed at both ends, counteracts the horizontal centrifugal force, retaining only the vertical vibration. This design is suitable for concentrating compaction energy in compaction devices.
[0013] 2. The vibratory tamping device used in this construction project, through the arrangement of a fixed frame, rotating rod, springs, dampers, and isolation shell, has a shock-absorbing structure composed of springs and dampers installed on the inner wall of the fixed frame during use. One end of the fixed frame is installed on the rotating plate. When the rotating plate swings on the inner wall of the fixed frame, it continuously compresses the springs and dampers on both sides, causing the springs and dampers to deform and absorb the vibration when the device swings excessively. At the same time, an isolation shell is installed outside the internal vibration device to reduce the noise emitted by the internal structure. This arrangement can improve the stability of the device during operation and reduce the impact of external noise from the device on the construction site. Attached Figure Description

Detailed Implementation
[0016] 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.
[0017] Please see Figures 1-4As shown, this utility model provides a technical solution: a vibratory tamping device for construction, including a tamping assembly 1 and a vibration damping and noise reduction assembly 2. The tamping assembly 1 consists of a fixed frame 101, a rotating frame 102, a rotating rod 103, a fixed cylinder 104, a rotating shaft 105, an eccentric wheel 106, a transmission belt 107, a fixed shaft 108, and a stepping motor 109. The rotating frame 102 is fixedly connected to the top of the fixed frame 101. The rotating rod 103 is rotatably connected to the inner wall of the rotating frame 102. The fixed cylinder 104 is fixedly connected to the bottom of the rotating rod 103. The rotating shaft 105 is rotatably connected to the inner wall of the fixed cylinder 104. The eccentric wheel 106 is fixedly connected to both ends of the rotating shaft 105. A transmission belt 107 is arranged at the center of the outer surface of the rotating shaft 105. The fixed shaft 108 is arranged at one end of the inner wall of the transmission belt 107. The stepping motor 109 is fixedly connected to one end of the fixed shaft 108. The tamping assembly 1 is connected to the fixed frame 101, the rotating frame 102, the rotating rod 103, the fixed cylinder 104, the rotating shaft 105, the eccentric wheel 106, the fixed cylinder 107, the fixed shaft 108, and the stepping motor 109. The setup of the moving frame 102, rotating rod 103, fixed cylinder 104, rotating shaft 105, eccentric wheel 106, transmission belt 107, fixed shaft 108, and advancing motor 109 allows the operator to start the device by holding it. This causes the advancing motor 109 to drive the fixed shaft 108 to rotate, which in turn drives the transmission belt 107. The transmission belt 107 then drives the rotating shaft 105 inside the fixed cylinder 104 to rotate, which in turn drives the eccentric wheels 106 at both ends to rotate. During rotation, centrifugal force (a periodically changing inertial force) is generated, resulting in vertical vibration. The rotating rod 103 on the fixed cylinder 104 swings within the rotating frame 102 on the inner wall of the fixed frame 101. This setup, with the eccentric wheels 106 rotating at the same high speed at both ends, can counteract the horizontal centrifugal force, retaining only the vertical vibration. This is suitable for tamping devices that concentrate compaction energy. The vibration damping and noise reduction component 2 consists of a spring 201, a damper 202, and an isolation shell 203 fixed to the inner wall of the fixed frame 101. The damper 202 is installed on the inner wall of the spring 201, and the isolation shell 203 is fixedly connected to the top of the fixed frame 101. Through the arrangement of the fixed frame 101, the rotating rod 103, the spring 201, the damper 202, and the isolation shell 203, in use, the vibration damping structure composed of the spring 201 and the damper 202 is installed on the inner wall of the fixed frame 101. One end is installed on the rotating plate. When the rotating plate swings on the inner wall of the fixed frame 101, it will continuously compress the spring 201 and the damper 202 on both sides, causing the spring 201 and the damper 202 to continuously deform and absorb the vibration when the device swings excessively. At the same time, the isolation shell 203 is installed outside the internal vibration device to reduce the noise emitted by the internal structure. This arrangement can improve the stability of the device during operation and reduce the impact of the device's external noise on the construction site. A mounting bracket 3 is fixedly connected to one end edge of the fixed frame 101. The inner wall of the mounting bracket 3 is fixedly connected to one end of the progress motor 109. With the fixed frame 101, the mounting bracket 3 and the progress motor 109, the progress motor 109 is installed inside the fixed frame 101 through the mounting bracket 3 during use. The rotating rod 103 has circular slots at the center of both sides. The inner wall of the circular slots is fixedly connected to one end of the damper 202. With the setting of the rotating rod 103 and the damper 202, when in use, one end of the damper 202 is installed in the circular slot on the rotating rod 103. A rotating groove is provided at the center of the outer surface of the fixed cylinder 104. The inner wall of the rotating groove is provided at one end of the outer surface of the transmission belt 107. Through the arrangement of the fixed cylinder 104 and the transmission belt 107, the transmission belt 107 is connected to the rotating shaft 105 inside the fixed cylinder 104 through the rotating groove on the fixed cylinder 104 during use. The bottom of the fixed frame 101 is provided with a rectangular groove, and the inner wall of the rectangular groove is fixedly connected to the tamping plate 4. With the setting of the fixed frame 101 and the tamping plate 4, when the eccentric wheel 106 inside the fixed frame 101 rotates and vibrates, it will drive the tamping plate 4 to press down on the ground. The back of the isolation shell 203 is provided with a fixing groove, and a handle 5 is fixedly connected to the inner wall of the fixing groove. With the setting of the isolation shell 203 and the handle 5, when in use, the operator can hold the handle 5 on the isolation shell 203 to control the position of the device for tamping.
[0018] In this invention, the working steps of the device are as follows: First step: The staff starts the device by holding it, so that the advancing motor 109 drives the fixed shaft 108 to rotate, the fixed shaft 108 drives the transmission belt 107 to drive, the transmission belt 107 drives the rotating shaft 105 in the fixed cylinder 104 at one end to rotate, and the rotating shaft 105 drives the eccentric wheels 106 at both ends to rotate. When rotating, centrifugal force is generated, thus forming vertical vibration. The rotating rod 103 on the fixed cylinder 104 will swing in the rotating frame 102 on the inner wall of the fixed frame 101. The second step: A shock-absorbing structure consisting of a spring 201 and a damper 202 is installed on the inner wall of the fixed frame 101. One end is installed on the rotating plate. When the rotating plate swings on the inner wall of the fixed frame 101, it will continuously compress the spring 201 and the damper 202 on both sides, causing the spring 201 and the damper 202 to continuously deform and absorb the vibration when the device swings excessively. At the same time, an isolation shell 203 is installed outside the internal vibration device to reduce the noise emitted by the internal structure.
