Description

Technical field:

[0002] Concrete vibrator is a widely used machine in engineering construction. It is mainly used to vibrate the concrete evenly, make the concrete densely combined, eliminate the honeycomb surface of the concrete, and thus improve the strength of the concrete. It is suitable for the construction of various concrete structures, such as bridges, tunnels, water conservancy projects, airports, docks, houses and other construction projects. In the field of concrete construction, the vibrator is an indispensable and important tool. It plays an important role in ensuring the quality of concrete construction and improving engineering efficiency.

[0027] The lateral vibration assembly 2 includes an inner shell 21, a bidirectional synchronous motor 22, a rotating shaft 23, an eccentric mass 24, a first bearing 25, an upper bearing seat 26 and a lower bearing seat 27. The bidirectional synchronous motor 22 is fixedly connected to the middle of the inner wall of the inner shell 21, and the two output ends of the bidirectional synchronous motor 22 are fixedly connected to the rotating shaft 23. The eccentric mass 24 is fixedly connected to the middle of the outer walls of the two rotating shafts 23. The ends of the outer walls of the two rotating shafts 23 that are away from each other are rotatably connected to the upper bearing seat 26 and the lower bearing seat 27 through the first bearing 25 respectively. The outer walls of the upper bearing seat 26 and the lower bearing seat 27 are fixedly connected to the top and bottom of the inner wall of the inner shell 21 respectively, and the bottom of the connecting seat 17 is welded to the center of the upper surface of the upper bearing seat 26.

[0028] In this embodiment, specifically: an L-shaped shell 18 is fixedly connected to the outer side of the rear surface of the driving motor 11, the bottom of the outer side wall of the L-shaped shell 18 is fixedly connected to the outer shell 20 through a connecting tube 19, the outer side wall of the inner shell 21 is slidably connected to the inner side wall of the outer shell 20, and the inner shell 21 slides inside the outer shell 20, thereby limiting the inner shell 21.

[0029] In this embodiment, specifically: the outer wall of the inner shell 21 is provided with a plurality of sliding grooves 28 around the inner wall, and the inner wall of the outer shell 20 is provided with a plurality of sliding bars 29 around the inner wall. The inner wall of the sliding groove 28 is slidably connected to the outer wall of the sliding bar 29. The sliding groove 28 on the inner shell 21 slides along the outer wall of the sliding bar 29, thereby limiting the inner shell 21, thereby increasing the stability of the inner shell 21 sliding inside the outer shell 20.

[0030] In this embodiment, specifically: limiting frames 30 are welded on both sides of the outer wall of the driving motor 11, and the inner walls of the two limiting frames 30 are slidably connected with sliders 31, and the sides of the two sliders 31 that are away from each other are welded with handles 32, and a limiting column 33 is welded at the center of the inner top wall of the limiting frame 30. A limiting hole 34 is opened at the center of the upper surface of the slider 31, and the inner wall of the limiting hole 34 is slidably connected to the middle of the outer wall of the limiting column 33. The bottom of the limiting column 33 is welded to the center of the inner lower wall of the limiting frame 30. The slider 31 slides inside the limiting frame 30 to limit the slider 31, and the limiting hole 34 on the slider 31 slides along the outer wall of the limiting column 33 to limit the slider 31, thereby increasing the sliding stability of the slider 31.

[0031] In the present embodiment, specifically: shock absorbing springs 35 are sleeved on the upper and lower parts of the outer wall of the limiting column 33, and the ends of the two shock absorbing springs 35 that are far away from each other are respectively connected to the outer side of the center of the inner top wall and the inner bottom wall of the limiting frame 30, and the ends of the two shock absorbing springs 35 that are close to each other are respectively connected to the outer side of the center of the upper surface and the lower surface of the slider 31. The two shock absorbing springs 35 buffer the slider 31, thereby reducing the vibration of the handle 32.

[0032] In the present embodiment, specifically: a controller 36 is fixedly connected to the upper portion of the outer wall of the driving motor 11, and the input ends of the driving motor 11 and the bidirectional synchronous motor 22 are electrically connected to the output ends of the controller 36. By connecting the driving motor 11 and the bidirectional synchronous motor 22 to the controller 36, it is convenient to use the controller 36 to control the operation of the driving motor 11 and the bidirectional synchronous motor 22.

[0033] In this embodiment, specifically: the sides of the outer walls of the two rotating shafts 23 that are close to each other are rotatably connected to the limiting rings 38 through the second bearing 37, and the outer walls of the two limiting rings 38 are fixedly connected to the inner wall of the inner shell 21 close to the upper and lower parts of the bidirectional synchronous motor 22.

[0034] In this embodiment, specifically: an anti-skid shock-absorbing sleeve 39 is fixedly connected to the outer side wall of the handle 32, and the anti-skid shock-absorbing property of the anti-skid shock-absorbing sleeve 39 on the handle 32 improves the comfort of holding the handle 32.

[0035] The working principle or structural principle is that when in use, the output shaft 12 is driven by the driving motor 11 to drive the driving disk 13 to rotate. The rotation of the driving disk 13 drives the connecting seat 17 to reciprocate up and down through the linkage effect of the first pin shaft 14 and the second pin shaft 16, thereby driving the entire lateral vibration component 2 to vibrate vertically. The two rotating shafts 23 are driven to rotate synchronously by the bidirectional synchronous motor 22, thereby driving the eccentric block 24 to rotate. The rotation of the eccentric block 24 generates centrifugal force, thereby generating lateral vibration inside the inner shell 21. The shell 21 is connected to the vertical vibration component 1 through the connecting seat 17, so the lateral vibration will be superimposed on the vertical vibration to produce a composite vibration effect. The start and stop and speed of the drive motor 11 and the bidirectional synchronous motor 22 are controlled by the controller 36, so that the vibration mode and intensity of the vibration rod can be adjusted according to construction requirements, so that the vibration frequency and amplitude can reach an ideal state, thereby improving the construction quality. Through the setting of the shock-absorbing spring 35 and the anti-slip shock-absorbing sleeve 39, the vibration can be effectively reduced from being transmitted to the handle 32, thereby improving the comfort of operation and thus improving construction efficiency.
