Secondly, the structure of the auxiliary wheels needs to be adjusted for use. During the tamping of concrete, the auxiliary wheels need to be installed upwards. During transportation, the auxiliary wheels need to be removed and tightened downwards before use, which is a cumbersome process. Utility Model Content

[0026] Example 1

[0027] A concrete compacting device includes a compacting plate 1, a vibration motor 2 is fixedly installed in the middle of the compacting plate 1, a top frame 3 is installed above the compacting plate 1, and the top frame 3 and the compacting plate 1 are connected by a telescopic rod 10, and the telescopic direction of the telescopic rod 10 is the vertical direction. A pair of rollers 5 are respectively installed on both ends of the top frame 3, and the non-rolling end of the roller 5 is rotatably connected to the top frame 3, and a gear 6 is fixedly installed on the rotating end of the roller 5. Racks 7 in the vertical direction are installed on both ends of the compacting plate 1. The rack 7 is meshed with the gear 6.

[0028] like Figure 1 In the structure shown, the compacting device is in working state, the compacting plate 1 is attached to the concrete, and the compacting step is completed by turning on the vibration motor 2 to vibrate the concrete surface and moving the compacting device using the push rod 4. The top frame 3 located above the compacting plate 1 is pressed on the compacting plate 1 under the action of gravity, the telescopic rod 10 is in a retracted state, and the gear 6 is engaged with the lower end of the rack 7, that is, the roller 5 rotates to the top and does not contact the ground.

[0029] Figure 2 The structure is in the transportation state after the work is completed. The top frame 3 is lifted, and the tamping plate 1 falls relative to the top frame 3 under the action of gravity after it is no longer in contact with the ground, so that the telescopic rod 10 is in an extended state, and the rack 7 is in a falling state relative to the top frame 3, driving the roller 5 to rotate until it rotates to the maximum stroke of the telescopic rod 10. At this time, the roller 5 is at the bottom and in contact with the ground, supporting the tamping device, and the transportation is completed by pushing the push rod 4.

[0030] Figure 2 The handling process in the state solves the problem that the tilted tamping plate 1 touches the ground on one side, and the handling method using the auxiliary wheels is unstable and easy to shake. In addition, during the handling process, although the roller 5 has the degree of freedom of rotation direction, it can be affected by external forces to rotate and cause instability, but due to the meshing of the gear 6 and the rack 7, the rotation of the roller 5 requires the tamping plate 1 to rise to complete, and the tamping plate 1 in the vacant state and the vibration motor 2 installed on the tamping plate 1 make the gravity of the tamping plate 1 larger, conventional external forces cannot overcome the overall gravity of the tamping plate 1 and the vibration motor 2 to rotate the roller 5, and the handling state is stable.

[0031] Limiting blocks 8 are installed at the bottom of both ends of the top frame 3 to limit the rotation angle of the roller 5. The position of the limiting block 8 is at the point where the roller 5 is rolled and rotated to the vertical downward position and abuts against the limiting block 8. If the rotation angle of the roller 5 is not limited, when the telescopic rod 10 is at the maximum stroke, there may be an error when the roller 5 rotates to the lowest vertical state, causing the roller 5 to deviate by a certain angle, affecting its stability. Using the limiting block 8 to limit the rotation angle of the roller 5 can reduce the impact of the error.

[0032] Preferably, a magnet 9 is installed inside the limit block 8. Conventional external force needs to overcome the overall gravity of the tamping plate 1 and the vibration motor 2 to significantly rotate the roller 5, and such a large external force is usually not encountered during the transportation process, but it can cause the roller 5 to vibrate slightly, affecting the stability of the transportation process. After the magnet 9 is installed, the suction force of the magnet 9 is used to avoid small vibrations.

[0033] A buffer assembly is installed at the bottom of the top frame 3, and the buffer assembly includes a compression spring 11, a damper 12 and a pressure plate 13. The two ends of the damper 12 are fixedly connected to the top frame 3 and the pressure plate 13 respectively. The compression spring 11 is sleeved on the outside of the damper 12. The two ends of the compression spring 11 are fixedly connected to the top frame 3 and the pressure plate 13 respectively. The pressure plate 13 is located above the tamping plate 1. Traditional tamping devices all have a buffer device to reduce the vibration to the user. However, since the distance between the tamping plate 1 and the top frame 3 is adjustable, if the tamping plate 1 and the top frame 3 are fixedly connected by a buffer device, after switching to the transport state, the distance between the tamping plate 1 and the top frame 3 increases, and the compression spring 11 will be in a stretched state. The compression spring 11 in a stretched state will overcome a part of the gravity of the tamping plate 1, and then when subjected to external force, it is easier to make the roller 5 rotate, and the transport state is unstable. Disconnect the pressure plate 13 from the tamping plate 1, Figure 1 In the working state, the compression spring 11 is pressed between the tamping plate 1 and the top frame 3, and the shock absorption can be completed normally. Figure 2 In the transport state, the compression spring 11 will not stretch the tamping plate 1 to cause tension.

[0034] Two groups of first handles 14 are installed on the top frame 3, and the two groups of first handles 14 are fixedly installed on both sides of the top frame 3. A second handle 15 is arranged above the top frame 3, and the two ends of the second handle 15 pass through the top frame 3 and are fixedly connected to the tamping plate 1, and the second handle 15 and the top frame 3 are slidably connected. An anti-slip sleeve 16 is installed in the middle of the second handle 15. When switching from the working state to the transport state, the top frame 3 needs to be lifted and the tamping plate 1 needs to be lifted and the top frame 3 needs to be lifted and fall with gravity. The first handle 14 is installed to facilitate lifting the top frame 3. When switching from the transport state to the working state, the tamping plate 1 needs to be lifted and the top frame 3 needs to be lifted and fall with gravity. However, the tamping plate 1 in the transport state is above the roller 5, and it is inconvenient to squeeze the tamping plate 1. Therefore, the second handle 15 passing through and slidably connected to the top frame 3 is installed, and the second handle 15 is grasped to lift the tamping plate 1 and the top frame 3 needs to be lifted and fall with gravity, and then switch to the working state.

[0035] A notch 17 is provided on the tamping plate 1 for the roller 5 to rotate, leaving a rotation space for the roller 5 .

[0036] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
