Description

Technical Field

[0001] This utility model relates to the field of vibrator technology, specifically a flat plate vibrator. Background Technology

[0002] With the development of the times, concrete is used for construction and pouring in many places. It is widely used in industrial and civil buildings, dams and bridges. Because plate vibrators have the advantages of high excitation frequency, strong vibration force and small amplitude, they are often used to compact and surface compact concrete.

[0003] Existing plate vibrators are basically driven by a motor, which drives an eccentric device to perform centrifugal swinging, thereby causing the whole device to vibrate. However, the vibratory motor rotates at high speed during use, and the eccentric device performs centrifugal motion at high speed, which makes it unstable during use and affects the service life of the vibrator. Secondly, the motor generates heat during use, and an overly thick casing will cause poor heat dissipation, affecting the service life of the motor. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a flat plate vibrator to address the deficiencies of the prior art.

[0005] The purpose of this utility model is achieved through the following technical solution: a flat plate vibrator, comprising a vibrator housing, an eccentric rotor and a hydraulic motor, wherein the eccentric rotor is rotatably mounted inside the vibrator housing, the housing of the hydraulic motor is mounted on the vibrator housing, and the output shaft of the hydraulic motor is drively connected to the eccentric rotor.

[0006] Furthermore, both ends of the eccentric rotor are fixed with eccentric shafts, which are rotatably mounted inside the vibrator housing via bearings.

[0007] Furthermore, one of the eccentric shafts is connected to the output shaft of the hydraulic motor via a coupling.

[0008] Furthermore, the coupling includes a main coupling and a coupling slider. One end of the main coupling is threaded to the eccentric shaft, and the thread direction of the main coupling is consistent with the rotation direction of the hydraulic motor. The other end of the main coupling has a radial groove, and the coupling slider is matched and disposed in the radial groove. The end of the coupling slider away from the main coupling has a retaining groove, and the output shaft of the hydraulic motor is engaged in the retaining groove.

[0009] Furthermore, a bearing sleeve is fitted onto the bearing.

[0010] Furthermore, a front cover flange is provided at one end of the vibrator housing, and the front cover flange is connected to the mounting flange on the hydraulic motor housing.

[0011] Furthermore, a mounting plate is fixed to the side wall of the vibrator housing, and bolt mounting holes are provided on the mounting plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. The eccentric rotor is driven by a hydraulic motor. The hydraulic motor is driven by hydraulic oil, which can dissipate the heat generated by the hydraulic motor and extend its service life.

[0014] 2. The coupling slider can move within the radial groove of the main coupling, so that the output shaft of the hydraulic motor and the coupling form a flexible connection, effectively isolating the radial force generated by the rotation of the eccentric shaft and preventing it from acting directly on the output shaft of the hydraulic motor, thereby improving the stability and service life of the transmission system.

[0018] Example 1

[0019] like Figure 1 and Figure 2 As shown, a plate vibrator includes a vibrator housing 1, an eccentric rotor 2, and a hydraulic motor 3. The eccentric rotor 2 is rotatably mounted inside the vibrator housing 1, and the housing of the hydraulic motor 3 is mounted on the vibrator housing 1. The output shaft of the hydraulic motor 3 is connected to the eccentric rotor 2, and the hydraulic motor 3 drives the eccentric rotor 2 to rotate eccentrically, causing the eccentric rotor 2 to rotate and generate an unbalanced force, thereby driving the entire machine body to generate high-frequency vibration, ensuring stable and efficient vibration effect. The hydraulic motor 3 is driven by hydraulic oil, which can dissipate the heat generated by the hydraulic motor and extend the service life of the hydraulic motor.

[0020] Example 2

[0021] Based on Example 1, such as Figure 1 and Figure 2As shown, a front cover flange 9 is provided at one end of the vibrator housing 1. The front cover flange 9 is connected to the mounting flange on the housing of the hydraulic motor 3. The vibrator housing 1 is installed through itself along its own axis. The two ends of the vibrator housing 1 are respectively connected to the front cover flange 9 and the rear cover by bolts. The hydraulic motor 3 is installed through the flange for easy installation and disassembly. The hydraulic motor 3 is connected to the external hydraulic system through the hydraulic oil circuit. The hydraulic motor 3 receives high-pressure oil from the outside as a power source to drive the eccentric rotor 2 to rotate, thereby driving the vibrator to work. It can also dissipate heat from the hydraulic motor 3. A mounting plate 10 is fixed to the side wall of the vibrator housing 1. The mounting plate 10 has bolt mounting holes 11. The entire plate vibrator is fixed to the working platform by bolts, providing a reliable support foundation for the installation and use of the vibrator.

[0022] Example 3

[0023] Based on Embodiment 2, eccentric shafts 4 are fixed at both ends of the eccentric rotor 2. The eccentric shafts 4 are rotatably mounted in the vibrator housing 1 through bearings 5. Bearing sleeves 8 are fitted on the bearings 5. At least one bearing 5 is installed on each side of the eccentric shaft 4. The bearings 5 ​​are nested in the bearing sleeves 8 to bear radial force. The eccentric shaft 4 generates unbalanced force by rotating, thereby driving the entire machine body to generate high-frequency vibration, ensuring stable and efficient vibration effect. The bearings 5 ​​are preferably deep groove ball bearings.

[0024] Example 4

[0025] Based on Example 3, such as Figure 2 As shown, one eccentric shaft 4 is connected to the output shaft of the hydraulic motor 3 via a coupling. The coupling includes a main coupling 6 and a coupling slider 7. One end of the main coupling 6 is threaded to the eccentric shaft 4, and the thread direction of the main coupling 6 is consistent with the rotation direction of the hydraulic motor 3. The other end of the main coupling 6 has a radial groove, and the coupling slider 7 is matched and disposed in the radial groove. The end of the coupling slider 7 away from the main coupling 6 has a retaining groove, and the output shaft of the hydraulic motor 3 is engaged in the retaining groove. The retaining groove matches the shape of the end of the output shaft of the hydraulic motor 3, which can be cross-shaped or straight. The coupling slider 7 can move within the radial groove of the main coupling 6, so that the output shaft of the hydraulic motor 3 and the coupling form a flexible connection, effectively isolating the radial force generated by the rotation of the eccentric shaft 4 and preventing it from acting directly on the output shaft of the hydraulic motor 3, thereby improving the stability and service life of the transmission system.
