[0002] A vibrating compactor is a device used in fields such as geotechnical tests, road construction, and building engineering. It compacts materials such as soil, asphalt, and concrete through vibration to improve their density and strength. The working principle of a vibrating compactor is to utilize the exciting force generated by a vibrator fixed on an object to force the material to be compacted to perform vertical forced vibration, sharply reducing the internal friction between soil particles, making the particles approach each other, increasing the density, and thus achieving the purpose of compaction.

[0003] A surface vibrating compactor generally includes a test cylinder, a frame, a lifting mechanism and a vibrating mechanism installed on the frame. The lifting mechanism drives the vibrating mechanism to move up and down. The vibrating mechanism can abut against the upper end surface of the test cylinder under the drive of the lifting mechanism to perform vibrating compaction work. The lifting mechanism is generally a screw assembly, and the vibrating mechanism generally includes a vibrating motor, and the compaction effect is achieved through the vibration of the vibrating motor.

[0004] Currently, the test cylinder is generally installed at the bottom of the frame by bolts, so the adaptability to test cylinders of different sizes is small. Utility Model Content

DETAILED DESCRIPTION

[0032] The following is combined with Figures 1-3 This application is described in further detail.

[0033] The present application embodiment discloses a positioning structure of a vibratory compactor. Figure 1 and Figure 2, the positioning structure of the vibrating compactor includes at least three groups of positioning components 4, which are evenly distributed circumferentially on the frame 1. The space between the positioning components 4 forms an accommodating space for placing the test cylinder 2. After the test cylinder 2 is placed in the accommodating space, it is positioned by the positioning components 4. In this embodiment, the positioning components 4 are preferably set to four groups. In other embodiments, they can also be set to three groups, five groups, etc.

[0034] Refer to Figure 2 and Figure 3 , the positioning component 4 includes a fixed block 41 and a fixing member 42 installed on the frame 1 and used to position the fixed block 41. The fixed block 41 can be adjusted along the radial direction of the adjusting cylinder on the frame 1, so as to adjust the size of the accommodating space to adapt to the size of the test cylinder 2. The fixing member 42 includes a locking column 421 threadedly connected to the surface of the frame 1 and a pressing block 422 fixed to the upper end of the locking column 421. The fixed block 41 is integrally in the shape of a rectangular block, and a relief groove 5 is opened on the fixed block 41. The length direction of the relief groove 5 is parallel to the length direction of the fixed block 41. The locking column 421 passes through the relief groove 5 and is threadedly connected to the frame 1, and when the pressing block 422 presses against the surface of the fixed block 41 to fix the fixed block 41.

[0035] Refer to Figure 2 and Figure 3 , the test cylinder 2 is usually in the shape of a cylinder, and a ring edge 3 is provided on the lower side wall of the test cylinder 2. In the prior art, the ring edge 3 is usually fixed to the frame 1 by bolts. In this embodiment, the fixed block 41 abuts against the upper surface of the ring edge 3, and then the fixed block 41 is fixed by the fixing member 42. Under the action of multiple fixed blocks 41, the test cylinder 2 is fixed. Further, in order to improve the positioning effect of the fixed block 41 on the test cylinder 2, a stepped edge 6 is opened on the lower surface of the end of the fixed block 41 close to the accommodating space. The ring edge 3 of the test cylinder 2 abuts against the stepped edge 6, and the stepped edge 6 restricts the possibility of the test cylinder 2 disengaging upward.

[0036] In a further embodiment, an arc-shaped arm 7 is fixed to the side wall of the fixed block 41. The arc-shaped arm 7 is in the shape of an arc and has an L-shaped cross-section. When the ring edge 3 abuts against the stepped edge 6, the arc-shaped arm 7 abuts against the side wall of the ring edge 3, and the extended part on the upper side of the arc-shaped arm 7 can abut against the upper surface of the ring edge 3, thereby further improving the positioning effect on the ring edge 3.

[0037] Further, in order to improve the fixing effect of the fixed block 41, a through rod 8 is slidably penetrated on the fixed block 41, and a connecting block 9 is fixed at the lower end of the through rod 8, and the size of the connecting block 9 is larger than the diameter of the through rod 8. A sliding groove 10 for sliding the connecting block 9 is provided on the upper surface of the frame 1, and the sliding groove 10 is a shrinking structure, so that the connecting block 9 cannot be separated from the sliding groove 10. The cross section of the sliding groove 10 can be a T-shaped structure, and during molding, a square groove can be provided on the upper surface of the frame 1, and the connecting block 9 is placed in the square groove and then welded to fix the shrinking part. The upper end of the through rod 8 is threadedly connected with a threaded block 11, and the threaded block 11 can be pressed against the surface of the fixed block 41, and under the joint action of the pressing block 422 and the threaded block 11, the positioning effect of the fixed block 41 is improved. And when the fixed block 41 needs to be adjusted, the connecting block 9 can slide in the sliding groove 10 synchronously.

[0038] Furthermore, the end of the fixing block 41 is threadedly connected with a positioning member 16 , which is preferably a bolt, the end of which extends into the stepped edge 6 and presses against the surface of the annular edge 3 , thereby further improving the positioning effect of the test tube 2 .

[0039] In order to reduce the loosening of the abutting block 422 and the threaded block 11 during operation, a sliding seat 12 is slidably mounted on the fixed block 41. The sliding seats 12 are symmetrically mounted on both sides of the clearance groove 5, and two sliding seats 12 are mounted on each side. A resisting member 13 is mounted on the sliding seat 12. The resisting members 13 on the two opposing sliding seats 12 are respectively abutted against the abutting block 422 and the threaded block 11. Under the action of the resisting member 13, the possibility of the abutting block 422 and the threaded block 11 rotating is limited.

[0040] Reference Figure 2 and Figure 3 The upper surface of the fixing block 41 is symmetrically fixed with fixing bars 14 on both sides of the clearance groove 5, and the fixing bars 14 are provided with a sliding cavity 15, and the sliding seat 12 slides in the sliding cavity 15. Furthermore, the upper and lower surfaces of the sliding seat 12 are fixed with guide blocks 17, and the inner wall of the sliding cavity 15 is provided with a guide groove 18, and the sliding seat 12 slides under the cooperation of the guide groove 18 and the guide block 17.

[0041] The resistance member 13 includes a resistance rod 131 on the threaded crocodile sliding seat 12 and a resistance plate 132 rotatably connected to the end of the resistance rod 131. The resistance plate 132 is an arc-shaped structure, and the resistance plate 132 can be pressed against the side walls of the pressing block 422 and the threaded block 11 by rotating the resistance rod 131. Furthermore, the side walls of the pressing block 422 and the threaded block 11 are rough structures, preferably vertical striped structures. The end of the resistance plate 132 facing away from the resistance rod 131 is also a rough structure. When the resistance plate 132 is pressed against the pressing block 422, the pressing block 422 and the threaded block 11 are positioned to reduce the possibility of loosening. The sliding seat 12 is positioned under the reaction force of the resistance rod 131.

[0042] The implementation principle of the positioning structure of a vibratory compactor in the embodiment of the present application is as follows: by adjusting the position of the fixed block 41, the test tube 2 of different diameters can be positioned. The fixed block 41 works together with the clamping block 422 and the threaded block 11 to make the positioning of the fixed block 41 more stable.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
