Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See Figures 1-3In this embodiment of the present invention, a vibrator for concrete pouring includes a slide plate 1, a fixed frame 3 fixedly connected to the slide plate 1, a rotating frame 4 rotatably connected to the fixed frame 3, multiple sets of equidistantly distributed front forks 5 fixedly connected to the rotating frame 4, a fixed cylinder 6 fixedly connected inside the front forks 5, a vibrator 7 disposed at the bottom of the fixed cylinder 6, a piston cylinder 8 disposed inside the vibrator 7, the bottom of the fixed cylinder 6 slidably connected to the piston cylinder 8, a piston block 9 slidably connected inside the piston cylinder 8, the piston block 9 fixedly connected to the fixed cylinder 6, a first spring 10 disposed inside the piston cylinder 8, a hydraulic cylinder 11 fixedly connected to the top of the fixed cylinder 6, a limit plate 12 fixedly connected to the side of the hydraulic cylinder 11 near the fixed cylinder 6, a drive plate 13 slidably connected to the top of the limit plate 12 inside the hydraulic cylinder 11, and a connecting rod fixedly connected to the drive plate 13. One end of rod 26 and the other end of connecting rod 26 pass through fixed cylinder 6 and are fixedly connected to the bottom of piston cylinder 8. An oil outlet 15 is provided in the side wall of the hydraulic cylinder 11 away from fixed cylinder 6. One end of connecting pipe 14 is provided between the limiting plate 12 and fixed cylinder 6 and is connected to the hydraulic cylinder 11. The other end of connecting pipe 14 is fixedly connected to tapping cylinder 16. An oil inlet 20 is provided in the side wall of tapping cylinder 16. A buffer cylinder 17 is fixedly connected to the side of tapping cylinder 16 away from connecting pipe 14. A piston plate 18 is slidably connected in the buffer cylinder 17. A second spring 19 is provided on the side of piston plate 18 away from tapping cylinder 16. A hydraulic pump 21 is installed on the slide plate 1. The output end of hydraulic pump 21 is connected to oil inlet 20. The input end of hydraulic pump 21 is connected to oil outlet 15. A rotary lifting assembly is installed on the slide plate 1.

[0018] This invention increases the load-bearing area between the equipment and the concrete by setting the sliding plate 1, thereby preventing the equipment from sinking into the concrete. When the equipment is running, the rotating frame 4 is first controlled by the rotating lifting assembly to rotate and press down. The rotating frame 4 drives the vibrator 7 to descend and insert into the concrete. Then, the hydraulic pump 21 pressurizes and injects hydraulic oil into the tap cylinder 16. As the hydraulic oil is injected, the pressure in the tap cylinder 16 increases. At this time, the drive plate 13 cannot move under the elastic push of the first spring 10, while the piston plate 18 moves into the buffer cylinder 17 under the push of the hydraulic oil, compressing the second spring 19. When the piston plate 18 moves to the buffer... After the bottom of cylinder 17, the hydraulic oil in the buffer cylinder 17 can no longer be injected. At this time, the pressure in the hydraulic cylinder 11 increases rapidly until the pressure in the hydraulic cylinder 11 offsets the elastic force of the first spring 10. The hydraulic oil pushes the drive plate 13 to rise. The drive plate 13 drives the vibrator 7 to rise rapidly through the connecting rod 26. When the drive plate 13 passes the oil outlet 15, the hydraulic oil flows out rapidly along the oil outlet 15, and the first spring 10 quickly returns to its original position. This injects the hydraulic oil in the buffer cylinder 17 into the hydraulic cylinder 11 and flows out synchronously along the oil outlet 15. Then, the first spring 10 pushes the vibrator 7 to fall rapidly, thus realizing a set of lifting and lowering processes of the vibrator 7.

[0019] The process is then repeated to achieve reciprocating vibration of the vibrator 7, thereby vibrating the concrete through the vibration of the vibrator 7.

[0020] In one instance of this embodiment, please refer to Figures 1-3 The tail of the skateboard 1 is fixedly connected to a pusher 2, and the present invention uses the pusher 2 to push the skateboard 1.

[0021] In one instance of this embodiment, please refer to Figures 1-3 The rotary lifting assembly includes a fixed rod 22 fixedly connected to a fixed frame 3, a sliding block 23 slidably connected to the fixed rod 22, one end of a rotating arm 24 rotatably connected to the sliding block 23, and the other end of the rotating arm 24 rotatably connected to a rotating frame 4. A hydraulic telescopic pump 25 is fixedly connected to the fixed frame 3, and the output shaft of the hydraulic telescopic pump 25 is fixedly connected to the sliding block 23. In this invention, the hydraulic telescopic pump 25 drives the sliding block 23 to slide and extend along the direction of the fixed rod 22, the sliding block 23 drives the rotating arm 24 to rotate and lift, the rotating arm 24 drives the rotating frame 4 to rotate and lift, and thus the height of the vibrator 7 is adjusted by the rotation and lifting of the rotating frame 4.
