Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically to a plate compactor. Background Technology

[0002] A plate compactor is a widely used compaction machine in earthwork engineering, primarily used to improve soil density and bearing capacity through vibration or impact. The core principle of a plate compactor is to rearrange soil particles through mechanical vibration or impact, reducing porosity and thus improving soil density and stability.

[0003] Plate compactors are mainly divided into two types: internal combustion and electric vibratory plate compactors. Internal combustion plate compactors are powered by an internal combustion engine (such as a gasoline or diesel engine), while electric plate compactors rely on electricity. Internal combustion plate compactors: The internal combustion engine generates a powerful impact force through high-speed rotation, which drives an eccentric block to vibrate via a clutch, pulleys, and other transmission devices. The base plate and eccentric block are fixed together, so the direction of vibration can be changed by rotating the eccentric block. Electric plate compactors: An electric motor drives the vibratory device to generate vibration, thereby achieving the compaction of the foundation. The main working parameters of a plate compactor include the bottom area of ​​the working plate, the overall mass of the machine, the excitation force, and the excitation frequency. The excitation force is used to maintain the forced vibration of the material being compacted, while the excitation frequency directly affects the compaction efficiency and degree of compaction. Under the same excitation force, the higher the excitation frequency, the higher the compaction efficiency and density.

The disclosed plate compactor includes a plate compactor body, a tie rod and a movable support frame rotatably connected to the plate compactor body, a threaded hole plate fixedly connected to the movable support frame, and bolts passing through the tie rod and threadedly connected to the threaded holes on the threaded hole plate. A connecting rod is slidably connected through the movable support frame. One end of the connecting rod is threadedly connected and has a threaded bolt passing through it. Wheels are rotatably connected to both sides of the other end of the connecting rod, and a support rod is fixedly connected to the upper surface of the connecting rod at that end. Chinese Patent Application No. 201120250424.5 discloses a vibratory plate compactor. The disclosed plate compactor includes a plate compactor base plate and a base plate fixing seat. The plate compactor base plate is provided with a power device, a handrail, and a vibration device. The plate compactor base plate is installed on the base plate fixing seat. A primary shock-absorbing pad is provided between the plate compactor base plate and the base plate fixing seat. A secondary shock-absorbing pad is provided on the hinge shaft at the hinge joint between the handrail and the base plate fixing seat. A tertiary shock-absorbing pad is also provided between the bend of the handrail and the base plate fixing seat.

[0005] Plate compactors are typically operated by construction workers to compact the surface. During operation, the vibrations generated are transmitted to the workers. In the aforementioned prior art, the tie rods and movable support frames are directly connected to the plate compactor body. Therefore, the vibrations generated by the plate compactor body are transmitted to the workers through these tie rods and movable support frames. Prolonged and significant vibrations can lead to worker fatigue, reduce work efficiency, and cause damage to the plate compactor itself. Utility Model Content

[0006] The present invention aims to overcome the defects in the prior art and provide a plate compactor that can reduce vibration amplitude and reduce vibration damage.

[0007] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a plate compactor, comprising a compaction plate and a machine body suspended above the compaction plate, wherein the compaction plate is provided with a drive mechanism for providing vibration power, and the machine body is connected to the drive mechanism; a damping structure for vibration reduction is provided between the machine body and the drive mechanism, wherein the damping structure guides and transmits the vibration generated by the drive mechanism to the machine body in the horizontal direction, thereby reducing the vibration amplitude of the machine body.

[0008] As a preferred embodiment of the present invention, the damping structure includes a plurality of damping blocks that guide the horizontal transmission of vibration, and the plurality of damping blocks are respectively disposed at the ends of both sides of the drive mechanism.

[0009] As a preferred embodiment of this utility model, the body includes suspension portions located on both sides of the drive mechanism, with both ends of the suspension portions connected to corresponding shock-absorbing blocks.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1 As shown, a plate compactor includes a compaction plate 1 and a machine body 3 suspended above the compaction plate 1. The compaction plate 1 is provided with a drive mechanism 2 for providing vibration power, and the machine body 3 is connected to the drive mechanism 2. A damping structure 4 for vibration reduction is provided between the machine body 3 and the drive mechanism 2. The damping structure 4 guides the vibration generated by the drive mechanism 2 to the machine body 3 in the horizontal direction to reduce the vibration amplitude of the machine body 3.

[0023] Furthermore, the tamping plate 1 has a plate-like structure, and the machine body 3 is suspended directly above the tamping plate 1. A drive mechanism 2 is installed on the tamping plate 1, which provides vibration power to the tamping plate 1. The machine body 3 is fixedly connected to the drive mechanism 2. The machine body 3 allows for the manipulation of the plate compactor, thus facilitating its movement. A shock-absorbing structure 4 is installed on the drive mechanism 2, and the machine body 3 is connected to the drive mechanism 2 through the shock-absorbing structure 4. Under the action of the shock-absorbing structure 4, the vibration generated by the drive mechanism 2 is guided and transmitted to the machine body 3 in the horizontal direction, changing the direction of vibration and reducing the vibration amplitude of the machine body 3. This allows construction personnel to experience less vibration when operating the plate compactor, reducing their fatigue. At the same time, by reducing the vibration amplitude of the machine body 3, the damage to the plate compactor itself caused by excessive vibration is reduced.

[0024] The damping structure 4 includes several damping blocks 401 that guide the horizontal transmission of vibration. The damping blocks 401 are respectively disposed at the ends of both sides of the drive mechanism 2. Furthermore, the damping blocks 401 are disposed on the drive mechanism 2. Specifically, in this embodiment, four damping blocks 401 are disposed, and the four damping blocks 401 are respectively located at the four corners of the drive mechanism 2, that is, at the ends of both sides of the drive mechanism 2.

[0025] The fuselage 3 includes suspension portions 301 located on both sides of the drive mechanism 2. The two ends of the suspension portions 301 are connected to corresponding shock absorbers 401. Furthermore, the suspension portions 301 are suspended on opposite sides of the drive mechanism 2. The suspension portions 301 are inverted U-shaped structures. The ends of the suspension portions 301 are connected to the corresponding shock absorbers 401. The vibration is transmitted to the fuselage 3 in the horizontal direction through the shock absorbers 401, thereby reducing the vibration amplitude of the fuselage 3.

[0026] Since the driving mechanism 2 drives the ramming plate 1 to vibrate in the vertical direction, the machine body 3 will also vibrate in the vertical direction. In order to reduce the vibration amplitude of the machine body 3 in the vertical direction, a shock-absorbing pad 402 is set to reduce the vertical vibration of the machine body 3.

[0027] Specifically, the shock absorption structure 4 also includes several shock absorption pads 402 disposed on the top of the drive mechanism 2. The body 3 is provided with a connecting part 302 connected to the shock absorption pads 402, and the top of the shock absorption pads 402 is connected to the lower surface of the connecting part 302 to reduce the vibration amplitude of the body 3 in the vertical direction. Furthermore, in this embodiment, two shock absorption pads 402 are provided, and the two shock absorption pads 402 are respectively located at both ends of the top of the drive mechanism 2. The body 3 is provided with a connecting part 302, and the shock absorption pads 402 are respectively connected to both ends of the connecting part 302. The vibration amplitude of the body 3 in the vertical direction is reduced by the provided shock absorption pads 402.

[0028] In addition, the suspension part 301 is provided on opposite sides of the connecting part 302, and the suspension part 301 and the connecting part 302 are integrally formed. A plurality of connecting holes 3021 for connecting the machine body 3 are formed on the connecting part 302. The machine body 3 can be connected to the push rod through the connecting holes 3021, so that the construction personnel can easily operate the plate compactor. At the same time, the machine body 3 can also be connected to the excavator arm through the connecting holes 3021, which facilitates the use of the plate compactor and increases the application range of the plate compactor.

[0029] The drive mechanism 2 is located in the middle of the tamping plate 1. The drive mechanism 2 includes a drive motor 201 that provides vibration power to the tamping plate 1. The tamping plate 1 is provided with a motor base 2011 for fixing the drive motor 201. Furthermore, by setting the drive mechanism 2 in the middle of the tamping plate 1, the vibration generated by the drive mechanism 2 can be evenly distributed on the tamping plate 1, ensuring that the vibration amplitude of each part of the tamping plate 1 is the same. The drive motor 201 is fixed on the tamping plate 1 through the motor base 2011. Under the action of the drive motor 201, the tamping plate 1 provides vibration. The drive motor 201 is a hydraulic motor, which has the advantages of strong power and good reliability.

[0030] The output end of the drive motor 201 is connected to an eccentric wheel 202 that provides a vibration source. The tamping plate 1 is provided with a housing 203 covering the eccentric wheel 202. The output end of the drive motor 201 is connected to a drive shaft. The eccentric wheel 202 is mounted on the drive shaft. The drive shaft drives the eccentric wheel 202 to rotate, and the eccentric wheel 202 provides vibration power to the tamping plate 1. The housing 203 covers the eccentric wheel 202, and the housing 203 protects the eccentric wheel 202, thereby preventing debris and other impurities generated by vibration from damaging the eccentric wheel 202.

[0031] In addition, the shock-absorbing pads 402 are provided at both ends of the top of the housing 203, and the housing 203 is provided at both ends for mounting the shock-absorbing blocks 401. The mounting parts 2031 extend outward along the length of the housing 203. The mounting parts 2031 are plate-shaped structures. In this embodiment, four mounting parts 2031 are provided. The four mounting parts 2031 are located at the four corners of the housing 203, and the shock-absorbing blocks 401 are mounted on the corresponding mounting parts 2031.

[0032] Both ends of the tamping plate 1 have upwardly curved bends 101. Furthermore, the bends 101 prevent debris generated during operation from entering the tamping plate 1, thus avoiding damage to the drive mechanism 2 and the shock absorption structure 4. At the same time, the bends 101 prevent the tamping plate from damaging the ground during movement.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
