Description

Technical Field

[0001] This utility model relates to the field of pavers, specifically to an automatic amplitude adjustment vibration system with a tensioning device and a paver. Background Technology

[0002] During the construction process, the vibration amplitude of the paving system needs to be adjusted according to different paving materials and paving thicknesses.

[0003] Chinese invention patent application CN113897842A discloses a vibration mechanism, including an eccentric shaft, a fixed bearing seat, a movable bearing seat, a vibration beam, an eccentric sleeve, and positioning screws. When adjusting the vibration amplitude, the positioning screws are first removed, and then the eccentric sleeve is rotated relative to the eccentric shaft until the mounting hole corresponding to the desired amplitude is initially aligned with the threaded hole on the eccentric shaft. That is, during the adjustment of the amplitude of each section of the screed, the connecting bolts between the eccentric sleeve and the eccentric shaft need to be loosened first, and then the eccentric sleeve is manually rotated to a certain angle relative to the eccentric shaft before being reconnected and fixed to the eccentric shaft with bolts at the appropriate position. This method of manually disassembling bolts to adjust the amplitude is time-consuming, laborious, and very inconvenient.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the problem of time-consuming and labor-intensive manual bolt removal for amplitude adjustment in existing technologies, this utility model provides an automatic amplitude adjustment vibration system with a tensioning device. The vibration system includes: an eccentric shaft; a flange, sleeved on the circumferential outer side of the eccentric shaft and rotating synchronously with it; an adjustment groove formed on the flange, the adjustment groove having a first contact surface and a second contact surface; an eccentric sleeve, sleeved on the circumferential outer side of the eccentric shaft and adapted to connect with a vibration frame; an adjustment protrusion formed on the eccentric sleeve extending into the adjustment groove, the adjustment protrusion selectively abutting against the first contact surface or the second contact surface to form a first amplitude and a second amplitude; and a tensioning structure, including a tensioning sleeve sleeved on the circumferential outer side of the eccentric shaft and an elastic component abutting against the flange; the elastic component is configured to provide a preload force for the flange to engage with the eccentric sleeve.

[0006] This utility model discloses an automatic amplitude adjustment vibration system with a tensioning device, comprising an eccentric shaft, a flange, an eccentric sleeve, and a tensioning structure. The flange rotates synchronously with the eccentric shaft and has a first contact surface and a second contact surface. An adjustment protrusion is formed on the eccentric sleeve, which can selectively abut against the first and second contact surfaces. That is, the eccentric shaft drives the flange to rotate, the flange drives the eccentric sleeve to rotate, and thus drives the vibration frame to perform eccentric motion. When the eccentric shaft rotates forward, the adjustment protrusion contacts the first contact surface, causing the vibration frame to vibrate at a first amplitude; when the eccentric shaft rotates in reverse, the adjustment protrusion contacts the second contact surface, causing the vibration frame to vibrate at a second amplitude. The tensioning structure includes a tensioning sleeve and an elastic component. The elastic component adds preload to the flange and eccentric sleeve, preventing radial rotation of the eccentric sleeve in the non-working state. The tensioning sleeve is fitted around the circumferential outer side of the eccentric shaft, preventing dust and foreign objects from affecting the normal operation of the elastic component, flange, and eccentric sleeve. With the above-mentioned settings, the present invention provides an automatic amplitude adjustment vibration system with a tensioning device that can automatically adjust two different amplitudes by rotating the eccentric shaft in both directions. Furthermore, the tensioning structure is designed to prevent the eccentric sleeve from rotating radially when not in operation.

[0007] Furthermore, a tensioning seat is provided on one side of the tensioning sleeve, and the two ends of the elastic member abut against the tensioning sleeve and the flange, respectively.

[0008] Furthermore, a locating key is provided on the eccentric shaft, and a keyway matching the locating key is provided on the flange. Through this arrangement, the eccentric shaft and the flange rotate synchronously via the keyway structure, resulting in low maintenance costs and a long service life.

[0009] Furthermore, a tensioning bolt is provided on the tensioning seat to abut against the tensioning sleeve. With the above arrangement, the preload of the tensioning spring can be adjusted by rotating the tensioning bolt, thereby adjusting the gap between the tensioning seat and the tensioning sleeve.

[0010] Furthermore, the elastic component is one of a helical spring, a disc spring, or a rubber element. With the above-described configuration, the spring and rubber element have a simple and reliable structure, and are easy and convenient to install and disassemble.

[0011] Furthermore, a first amplitude mark and a second amplitude mark are formed on the eccentric sleeve, and a limit mark is formed on the flange; the first amplitude mark is configured to align with the limit mark when the adjusting protrusion abuts against the first contact surface, and the second amplitude mark is configured to align with the limit mark when the adjusting protrusion abuts against the second contact surface. Through the above configuration, the first amplitude mark, the second amplitude mark, and the limit mark can conveniently confirm whether the vibrator is at the first amplitude or the second amplitude.

[0012] Furthermore, it also includes a bearing housing suitable for connection with the vibratory frame, and a movable bearing is provided between the bearing housing and the eccentric sleeve. With the above arrangement, the eccentric sleeve drives the movable bearing to make eccentric movements, which in turn drives the bearing housing to make eccentric movements, and the vibratory frame moves up and down accordingly.

[0013] To improve or solve the technical problem of the time-consuming and labor-intensive method of manually disassembling bolts to adjust the amplitude in existing technologies, this utility model provides a paver. The paver includes a vibratory frame; and an automatic amplitude-adjusting vibratory system with a tensioning device as described above; the vibratory frame is connected to the eccentric sleeve of the automatic amplitude-adjusting vibratory system with a tensioning device. By using the aforementioned automatic amplitude-adjusting vibratory system with a tensioning device, this utility model paver can automatically adjust two different amplitudes by rotating the eccentric shaft in both directions, and the tensioning structure prevents the eccentric sleeve from rotating radially when not in operation.
