Description

Technical Field

[0001] This application relates to the field of concrete vibration technology, and in particular to a concrete vibration device. Background Technology

[0002] Existing concrete vibration devices mainly consist of a vibrating rod, which is the part that comes into direct contact with the concrete. It transfers energy to the concrete through vibration, thereby achieving compaction and density. The power of the vibrating rod mainly comes from an electric motor, which generates rotational force. This rotational force is first transmitted to the transmission device. The centrifugal force generated by the high-speed rotation of the rotating shaft with eccentric mass installed at the center of the vibrating rod is transmitted to the vibrating housing through the bearing, thereby causing the vibrating rod to produce circumferential vibration.

[0003] The existing technical solutions mentioned above have the following drawbacks: the length of the vibrator is fixed, which is not adaptable to concrete layers of different depths. Utility Model Content

[0004] This application provides a concrete vibration device for vibrating concrete layers of different depths.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0006] A concrete vibrating device includes a mounting cylinder closed at both ends, a drive sleeve rotatably disposed within the mounting cylinder, and a telescopic cylinder slidably disposed within the drive sleeve. A circular hole communicating with the inside and outside is coaxially opened on one end face of the mounting cylinder. One end of the drive sleeve is closed, and the closed end of the drive sleeve is away from the circular hole. Both ends of the telescopic cylinder are closed, and the end of the telescopic cylinder away from the closed end of the drive sleeve passes through the circular hole. The drive sleeve drives the telescopic cylinder to slide along its axial direction.

[0007] By adopting the above technical solution, and by setting up an installation cylinder, a drive sleeve, and a telescopic cylinder, the installation cylinder has a circular hole coaxially opened on one end face that connects the inside and outside. This allows the telescopic cylinder to slide axially under the drive of the drive sleeve, changing the overall length of the vibrating device. This adapts to concrete layers of different depths, enabling the vibration of concrete layers of different depths and improving the problem of insufficient adaptability caused by the fixed length of the vibrator in the existing technology.

[0008] Optionally, the drive sleeve has a threaded drive groove that connects the inside and outside of the drive sleeve, and a drive component is fixedly installed on the peripheral wall of the telescopic cylinder. The drive component can slide along the drive groove. The vibrating device also includes a motor, which is installed inside the mounting cylinder, and the end of the motor output shaft is fixedly connected to the outer wall of the closed end of the drive sleeve.

[0009] By adopting the above technical solution, by opening a drive groove and setting a drive component and a motor, the rotation of the motor output shaft can drive the drive sleeve to rotate, so that the drive component slides along the threaded drive groove, thereby driving the telescopic cylinder to slide along the drive sleeve axially, providing a stable power source for the extension and retraction of the telescopic cylinder, ensuring the smoothness of the length adjustment process of the vibrating device, and meeting the length requirements of concrete vibration at different depths.

[0010] Optionally, a limiting groove is formed on the inner peripheral wall of the mounting cylinder, and the end of the driving component is slidably disposed in the limiting groove, the length direction of the limiting groove being parallel to the axis of the mounting cylinder.

[0011] By adopting the above technical solution and by opening a limiting groove, the movement trajectory of the driving component can be constrained by the limiting groove when the driving component slides with the driving groove, so that the driving component only moves in a direction parallel to the axis of the mounting cylinder, thereby driving the telescopic cylinder to slide smoothly along the axial direction, avoiding the telescopic cylinder from rotating during the movement, and ensuring the stability of the telescopic adjustment.

[0012] Optionally, the circular hole wall is coaxially provided with an annular sealing groove, and an annular sealing ring of rubber material is coaxially provided in the sealing groove, with the peripheral wall of the sealing ring slidingly attached to the outer peripheral wall of the telescopic cylinder.

[0013] By adopting the above technical solution and setting a sealing ring, the gap between the installation cylinder and the telescopic cylinder can be sealed by the tight sliding fit between the rubber sealing ring and the outer peripheral wall of the telescopic cylinder, reducing the possibility of concrete entering the interior of the installation cylinder.

[0014] Optionally, the end face of the drive sleeve away from the closed end abuts against the inner wall of the end of the mounting sleeve with a circular hole.

[0015] By adopting the above technical solution, the axial position of the drive sleeve in the mounting cylinder can be restricted by the end face of the drive sleeve away from the closed end abutting against the inner wall of the end of the mounting cylinder with the circular hole. This reduces the possibility that the end of the drive sleeve with the circular hole in the mounting cylinder will displace and separate from the mounting cylinder during the rotation or sliding of the telescopic cylinder.

[0016] Optionally, the outer wall and end face of the mounting cylinder away from the motor and the outer wall and end face of the drive sleeve away from the motor are both machined into arc surfaces.

[0017] By adopting the above technical solution, by processing the outer wall and end face of the end of the mounting cylinder away from the motor and the outer wall and end face of the end of the drive sleeve away from the motor into arc surfaces, the smoothness of the arc surfaces can be utilized to reduce the amount of concrete adhering to the ends of the mounting cylinder and drive sleeve during vibration, and reduce the difficulty of cleaning the device after vibration.

[0018] Optionally, the vibrating device further includes a rotating shaft rotatably disposed inside the telescopic cylinder and a counterweight disposed on the circumferential wall of the rotating shaft. The two ends of the rotating shaft are respectively rotatably disposed in the inner walls of the two ends of the telescopic cylinder. The circumferential wall of the rotating shaft is spaced apart from the inner wall of the telescopic cylinder, and the surface of the counterweight is spaced apart from the inner wall of the telescopic cylinder.

[0019] By adopting the above technical solution, and by setting a rotating shaft and a counterweight, centrifugal force can be generated when the rotating shaft rotates, by means of the eccentric distribution of the counterweight, which in turn drives the telescopic cylinder to vibrate, thereby realizing the function of vibrating concrete.

[0020] Optionally, the vibrating device also includes a transmission flexible shaft disposed on the telescopic cylinder opposite to the motor end face, wherein the transmission flexible shaft is coaxially fixed to the telescopic cylinder and the end face of the rotating shaft.

[0021] By adopting the above technical solution and setting a flexible transmission shaft, external power can be stably transmitted to the rotating shaft, driving the rotating shaft to rotate continuously inside the telescopic cylinder.

[0022] In summary, this application has the following technical effects:

[0023] 1. By setting up an installation cylinder, a drive sleeve, and a telescopic cylinder, and a circular hole coaxially opened on one end face of the installation cylinder to connect the inside and outside, the telescopic cylinder can slide axially under the drive of the drive sleeve, changing the overall length of the vibrating device, thereby adapting to concrete layers of different depths, realizing the vibration of concrete layers of different depths, and improving the problem of insufficient adaptability caused by the fixed length of the vibrating rod in the existing technology.

[0024] 2. By setting up a drive component and a motor, the rotation of the motor output shaft can drive the drive sleeve to rotate, causing the drive component to slide along the threaded drive groove, thereby driving the telescopic cylinder to slide along the axial direction of the drive sleeve. This provides a stable power source for the extension and retraction of the telescopic cylinder, ensuring the smoothness of the length adjustment process of the vibrating device and meeting the length requirements of concrete vibration at different depths.

[0025] 3. By setting a rotating shaft and a counterweight, centrifugal force can be generated when the rotating shaft rotates, which in turn drives the telescopic cylinder to vibrate, thus realizing the function of vibrating concrete. Attached Figure Description

[0030] This application discloses a concrete vibration device, referring to... Figure 1 The vibrating device includes a telescopic component 1 and a vibrating component 2 installed on the telescopic component 1.

The vibrating component 2 enables the telescopic component 1 to realize the vibration function and perform vibration work on the concrete layer.

[0031] Reference Figure 2 The telescopic assembly 1 includes a mounting cylinder 11 closed at both ends, a drive sleeve 13 rotatably disposed within the mounting cylinder 11, a telescopic cylinder 14 slidably disposed within the drive sleeve 13, and a motor 16 disposed inside the mounting cylinder 11. The mounting cylinder 11 is cylindrical, and a circular hole 111 is opened on one end face of the mounting cylinder 11, the circular hole 111 connecting the inside and outside of the mounting cylinder 11. The drive sleeve 13 is rotatably disposed within the mounting cylinder 11, the outer peripheral wall of the drive sleeve 13 is adapted to the inner wall of the mounting cylinder 11 and the outer peripheral wall of the drive sleeve 13 is in contact with the inner wall of the mounting cylinder 11, and the inner wall of the drive sleeve 13 is flush with the inner peripheral wall of the circular hole 111.

[0032] Combination Figure 1 and Figure 2 The telescopic cylinder 14 is a closed cylinder at one end, with the closed end of the telescopic cylinder 14 close to the mounting cylinder 11. The telescopic cylinder 14 is adapted to and slides within the driving sleeve 13. The outer peripheral wall of the telescopic cylinder 14 is in contact with the inner peripheral wall of the driving sleeve 13. The end of the telescopic cylinder 14 away from the driving sleeve 13 passes through a circular hole 111. A threaded driving groove 131 is formed on the peripheral wall of the driving sleeve 13, connecting the inside and outside of the driving sleeve 13. A driving member 15 is provided on the peripheral wall of the telescopic cylinder 14. The driving member 15 is cylindrical, and its axis coincides with the axis of the telescopic cylinder 14. The end face of the driving sleeve 13 away from the closed end abuts against the inner wall of the end of the mounting cylinder 11 with the circular hole 111, reducing the possibility of separation between the driving cylinder and the mounting cylinder 11. The driving member 15 is inserted into the peripheral wall of the driving sleeve 13 and slidably disposed in the driving groove 131, with the peripheral wall of the driving member 15 slidingly in contact with the groove wall of the driving groove 131.

[0033] Combination Figure 1 and Figure 2A limiting groove 12 is formed on the inner circumferential wall of the mounting cylinder 11. The length direction of the limiting groove 12 is parallel to the axis of the mounting cylinder 11. The end of the driving component 15 away from the telescopic cylinder 14 is adapted to the limiting groove 12 and slidably disposed in the limiting groove 12 to prevent the telescopic cylinder 14 from rotating during movement and reducing working efficiency. The motor 16 is fixedly disposed inside the mounting cylinder 11. The output shaft of the motor 16 is fixedly connected to the outer wall of the closed end of the drive sleeve 13, and the output shaft of the motor 16 is coaxial with the drive sleeve 13.

[0034] Combination Figure 1 and Figure 2 When adjusting the length of the vibratory compaction device, the motor 16 causes the drive sleeve 13 to rotate, causing the drive component 15 to slide along the drive groove 131 and the limiting groove 12, driving the telescopic cylinder 14 to move away from the motor 16. The outer wall of the closed end of the mounting cylinder 11 is machined into a spherical surface. The outer wall and end face of the end of the mounting cylinder 11 away from the motor 16 and the outer wall and end face of the end of the drive sleeve 13 away from the motor 16 are all machined into arc surfaces to reduce concrete adhesion during vibration.

Both ends of the rotating shaft 22 are rotatably disposed within the inner walls of both ends of the telescopic cylinder 14, with the peripheral wall of the rotating shaft 22 spaced apart from the inner wall of the telescopic cylinder 14. The counterweight 23 is strip-shaped, with its length parallel to the axis of the telescopic cylinder 14. Both end faces and side walls of the counterweight 23 are spaced apart from the inner wall of the telescopic cylinder 14. During the rotation of the rotating shaft 22, the counterweight 23 generates an eccentric force, thus producing vibration. The transmission flexible shaft 21 transmits power to the telescopic cylinder 14, which is coaxially fixed to the end face of the rotating shaft 22, providing rotation for the rotating shaft 22.
