Ends 2 are fixed at both ends of the vibration beam 1 to provide a stable structure for it. An L-shaped plate 6 is welded on the inner wall of one side and the inner wall of the bottom of the vibration beam 1, which plays a supporting and connecting role. A sliding plate 7 is slidably connected between the vibration beam 1 and the L-shaped plate 6, so that the sliding plate 7 can slide freely on the vibration beam 1.

The vibrator 17 is clamped by the L-shaped plate 6 and the pressing block 14, and is firmly fixed by the pressing block 14 to ensure the stable operation of the vibrator 17 during the concrete leveling process.

[0049] Reference Figure 5 and Figure 8 In addition, there is a protective cover plate 22, which is slidably set on the top inner wall of the L-shaped plate 6. The bottom of the cover plate 22 slides through a sliding platform 21, and the sliding platform 21 is slidably connected to the top of the sliding plate 7. This design allows the cover plate 22 and the sliding platform 21 to slide when needed to perform various operations.

[0050] Reference Figure 2 and Figure 3 On one side of the vibration beam 1, a flattening rod 34 is also provided, and its function is to flatten the concrete to ensure the flatness of the concrete surface.

[0051] Reference Figure 4 , Figure 5 , Figure 7 and Figure 8In order to realize the rapid installation of the handle 4 and the sliding plate 7, a first fixing structure is provided in the device, which includes a baffle 10 fixed to the top of the sliding plate 7, the baffle 10 is used to limit the connecting seat 9, two limiting plates 11 are fixed on one side of the baffle 10, the bottom of the limiting plate 11 abuts against the top of the connecting seat 9, and is used to limit the connecting seat 9 in the vertical direction, and two rotating cavities 29 are provided on the top of the sliding plate 7, and the same rotating shaft 25 rotates in the two rotating cavities 29, and the outer wall of the rotating shaft 25 is fixedly sleeved with two L-shaped pressing plates 27, and the L-shaped pressing plate 27 is used to fix the connecting seat 9. The outer wall of the rotating shaft 25 is also fixedly sleeved with a plurality of first gears 26, and the handle 4 is fixedly penetrated through the connecting seat 9, and the bottom of the connecting seat 9 It is slidably connected to the top of the sliding plate 7 through a slider and a groove. In this way, when the handle 4 needs to be installed, it is only necessary to cooperate the groove at the bottom of the connecting seat 9 with the slider at the top of the sliding plate 7, slide the connecting seat 9 onto the sliding plate 7, and make the connecting seat 9 conflict with the baffle 10. At this time, the magnet 12 will magnetically adsorb the connecting seat 9, and the limit plate 11 will also be stuck on the top of the connecting seat 9 to limit the connecting seat 9. Then, the sliding table 21 drives the rotating shaft 25 and the L-shaped pressing plate 27 to rotate through the cooperation of the first rack 24 and the first gear 26, so that the L-shaped pressing plate 27 can just be pressed on the connecting seat 9, and the two right-angled sides on the inner side of the L-shaped pressing plate 27 just fit with the corresponding right-angled sides of the connecting seat 9, further fixing the connecting seat 9.

[0052] Reference Figure 3 , Figure 4 , Figure 6 and Figure 8 In order to achieve easy clamping and fixing of the vibrator 17 by the pressing block 14, a second fixing structure is provided in the device, which includes a plurality of arc-shaped pressing plates 16 fixed at the bottom of the pressing block 14, which are used to clamp the vibrator 17. A plurality of base plates 13 are fixed on the top of the L-shaped plate 6, and the plurality of base plates 13 are rotatably connected with the pressing block 14 through a hinge shaft. A locking plate 15 is fixed to one side of the bottom of the pressing block 14, and a clearance hole 19 is provided in the L-shaped plate 6 for making way for the locking plate 15. When the vibrator 17 needs to be fixed, the vibrator 17 only needs to be placed in the placement arc surface 18, and then the sleeve plate 22 pulls the locking plate 15 downward through the connecting rod 28, and the locking plate 15 drives the pressing block 14 to rotate, so that the pressing block 14 cooperates with the arc-shaped pressing plate 16 to complete the clamping and fixing of the vibrator 17.

[0053] Reference Figure 8 In addition, a driving structure is provided in the device, which is arranged between the sliding plate 7 and the L-shaped plate 6, and is used to synchronously drive the first fixed structure and the second fixed structure. In this way, when it is necessary to install the handle 4 or fix the vibrator 17, it is only necessary to operate the driving structure to complete these two tasks at the same time, which greatly improves the work efficiency.

[0054] Reference Figure 6-Figure 8 The driving structure is mainly composed of a threaded rod 23, a sleeve plate 22, a sliding plate 7, a sliding table 21, a first rack 24, a first gear 26, a rotating shaft 25, an L-shaped pressure plate 27 and a plurality of connecting rods 28. The threaded rod 23 threadably penetrates the L-shaped plate 6 (a locking nut is threadedly connected to the threaded rod 23. After adjusting the threaded rod 23, the locking nut is rotated so that the locking nut contacts the L-shaped plate 6 to fix the threaded rod 23), and one end thereof is rotatably connected to the sleeve plate 22. A slide groove 20 is provided on the top of the sliding plate 7. The bottom end of the sliding table 21 extends into the slide groove 20 and is slidably connected to the slide groove 20. In this way, the sliding table 21 can slide in the slide groove 20. A plurality of first racks 24 are fixed on one side of the sliding table 21. These first racks 24 penetrate the sliding plate 7 and mesh with the first gear 26. A plurality of connecting rods 28 are rotatably connected to one side of the sleeve plate 22. The top ends of these connecting rods 28 are hinged to the locking plate 15.

[0055] Reference Figure 6-Figure 8 When the leveling device needs to be installed or fixed, the threaded rod 23 can be rotated. When the threaded rod 23 rotates, it will drive the sliding table 21 to move outward through the sleeve plate 22. At the same time, the sleeve plate 22 will also pull the locking plate 15 downward through the connecting rod 28. When the locking plate 15 moves downward, it will drive the pressing block 14 to rotate. In this way, the cooperation between the pressing block 14 and the arc-shaped pressing plate 16 can complete the clamping and fixing of the vibrator 17. At the same time, when the sliding table 21 moves outward, it will also drive the rotating shaft 25 and the L-shaped pressing plate 27 to rotate through the cooperation between the first rack 24 and the first gear 26. After the L-shaped pressing plate 27 rotates, it will just be able to press on the connecting seat 9, further fixing the connecting seat 9, thereby preliminarily completing the installation of the leveling device.

[0056] Reference Figure 3-Figure 5 Secondly, in order to reduce the high-intensity vibration of the vibration beam 1 on the handle 4 during vibration, a vibration reduction structure is also provided in the device. The structure is arranged inside the vibration beam 1 and can effectively absorb and disperse the vibration energy, thereby ensuring that the operator does not feel discomfort when dragging the vibration beam 1.

[0057] Reference Figure 3-Figure 5 The vibration reduction structure is mainly composed of a plurality of vibration reduction dampers 8, which are fixed to the bottom inner wall of the vibration beam 1. At the same time, their top ends are fixedly connected to the bottom of the sliding plate 7. When the vibration beam 1 vibrates, the vibration reduction dampers 8 can reduce the vibration borne by the sliding plate 7. In this way, it can avoid the numbness of the hands of the staff when dragging the vibration beam 1 to move.

[0058] Reference Figure 2 , Figure 3 and Fig. 9Two connecting ears 30 are fixed on one side of the vibration beam 1, and the flattening rod 34 is located between the two connecting ears 30. Each connecting ear 30 is provided with an L-shaped groove 31 and an inclined groove 32, and the L-shaped groove 31 is connected to the inclined groove 32. Both ends of the flattening rod 34 are rotatable with rotating shafts 35, and these rotating shafts 35 are matched with the inclined groove 32 and the L-shaped groove 31. At the same time, bolts 33 are threadedly connected in the two connecting ears 30, and the bottom end of the bolt 33 extends into the L-shaped groove 31 to limit the rotating shaft 35. In this way, when the vibration beam 1 moves, the flattening rod 34 can flatten the concrete on one side of the vibration beam 1 first, which is convenient for the vibration beam 1 to smoothly level the concrete in the later stage.

[0059] Reference Figure 1 , Figure 3 and Fig.10 Two liquid storage tanks 36 are fixedly connected to the inner wall of the bottom of the vibration beam 1 of the portable underground concrete leveling device. The two liquid storage tanks 36 are located on both sides of the L-shaped plate 6 and are connected by a connecting pipe 37. The connecting pipe 37 is located below the sliding plate 7. The design of the liquid storage tanks 36 and the connecting pipe 37 increases the weight of the vibration beam 1. In actual applications, water can be injected into the liquid storage tanks 36 to increase the overall weight of the vibration beam 1 to ensure that the vibration beam 1 has enough weight to spread the concrete.

[0060] Reference Figure 1 and Figure 2 A plurality of connecting rods 5 arranged in sequence from top to bottom are fixed in the handle 4, and a through hole 39 is provided in the connecting rod 5 located at the top. Both ends of the through hole 39 pass through the handle 4 and cooperate with the flattening rod 34. This design allows the staff to easily drive the vibration beam 1 to move through the flattening rod 34. When one person feels strenuous in dragging the leveling device, the flattening rod 34 can be removed from between the two connecting ears 30 and inserted into the through hole 39. At this time, two staff members can jointly drag the leveling device to move through the flattening rod 34, thereby reducing the work intensity and improving the leveling efficiency.

[0061] Reference Figure 2 , Figure 4 and Figure 7 A leveling arc surface 38 is provided on one side of the vibration beam 1 and the end 2. This design allows the concrete to move smoothly to the bottom of the vibration beam 1 and the end 2. A placement arc surface 18 is provided on the top of the L-shaped plate 6 to facilitate the placement of the vibrator 17. In addition, a plurality of magnets 12 are fixedly embedded on one side of the baffle 10, and the connecting seat 9 is made of iron. The magnet 12 cooperates with the connecting seat 9 to adsorb the connecting seat 9, thereby enhancing the stability of the device.

[0062] Example 2

[0063] refer to Fig.11 and Fig.12, an improvement on Example 1: a rotating groove 3 is provided on the side of the L-shaped plate 6 away from the vibration beam 1, and a rotating rod 41 is rotatably connected in the rotating groove 3. A plurality of lighting lamps 40 are fixedly sleeved on the outer wall of the rotating rod 41 for lighting. A second gear 42 is also fixedly sleeved on the outer wall of the rotating rod 41. A second rack 43 is fixed on one side of the sleeve plate 22. One end of the second rack 43 slides and extends into the rotating groove 3 and meshes with the second gear 42. This design enables the sleeve plate 22 to drive the lighting lamp 40 and the rotating rod 41 to rotate through the cooperation of the second rack 43 and the second gear 42 when the threaded rod 23 drives the sleeve plate 22 and the sliding platform 21 to move outward. In this way, when the concrete is leveled in the later stage, the lighting lamp 40 can illuminate the field of view underground, which is convenient for the staff to observe the state of the concrete after leveling.

[0064] A method for using an underground portable concrete leveling device comprises the following steps:

[0065] S1. The relevant parts of the leveling device are carried underground. First, the groove at the bottom of the connecting seat 9 is matched with the slider at the top of the sliding plate 7, and the connecting seat 9 is slidably installed on the sliding plate 7. The connecting seat 9 is in conflict with the baffle 10, and the magnet 12 magnetically adsorbs the connecting seat 9. In addition, the limiting plate 11 can be stuck on the top of the connecting seat 9 to limit the connecting seat 9. Then, the vibrator 17 is placed in the placement arc surface 18, and the placement operation of the connecting seat 9 and the vibrator 17 is preliminarily completed;

[0066] S2, rotate the threaded rod 23, the threaded rod 23 drives the sliding table 21 to move outward through the sleeve plate 22, the sleeve plate 22 pulls the locking plate 15 downward through the connecting rod 28, the locking plate 15 drives the pressing block 14 to rotate, the pressing block 14 cooperates with the arc-shaped pressing plate 16 to complete the clamping and fixing of the vibrator 17, and the sliding table 21 drives the rotating shaft 25 and the L-shaped pressing plate 27 to rotate through the cooperation of the first rack 24 and the first gear 26, the L-shaped pressing plate 27 can just be on the connecting seat 9, and the two right-angled sides on the inner side of the L-shaped pressing plate 27 just fit with the corresponding right-angled sides of the connecting seat 9, further fixing the connecting seat 9, and preliminarily completing the installation of the leveling device;

[0067] S3, place the flattening rod 34 between the two connecting ears 30, the rotating shaft 35 enters the L-shaped groove 31, then push the flattening rod 34 upward obliquely, the rotating shaft 35 moves into the inclined groove 32, turn the bolt 33, the bolt 33 moves downward and limits the rotating shaft 35 to prevent the rotating shaft 35 from being separated from the inclined groove 32, and the installation of the flattening rod 34 is completed;

[0068] S4. When performing the leveling operation, the vibrator 17 is started, and the vibrator 17 drives the L-shaped plate 6 and the vibration beam 1 to vibrate. The worker drives the vibration beam 1 to move through the handle 4, and the vibration beam 1 transmits the vibration to the concrete, which can level the concrete. In addition, when the vibration beam 1 moves, the leveling rod 34 can first level the concrete on one side of the vibration beam 1, so that the vibration beam 1 can level the concrete smoothly in the later stage. In addition, water can be injected into the liquid storage tank 36 to increase the overall weight of the vibration beam 1, so that the vibration beam 1 has enough weight to level the concrete;

[0069] S5. When the vibration beam 1 vibrates, the connection seat 9 can reduce the vibration transmitted by the vibration beam 1 under the action of the vibration damping 8, so as to prevent the hands of the staff from being numb when dragging the vibration beam 1; in addition, when the threaded rod 23 drives the sleeve plate 22 and the sliding platform 21 to move outward, the sleeve plate 22 drives the lighting lamp 40 and the rotating rod 41 to rotate through the cooperation of the second rack 43 and the second gear 42, and the light emitting part of the lighting lamp 40 is rotated from the storage state (vertically downward) to the downward inclined state, and then in the later stage of concrete leveling, the lighting lamp 40 can illuminate the field of vision in the well, so that the staff can observe the state of the concrete leveled in the well;

[0070] S6. When one person is tired of dragging the leveling device, the leveling rod 34 is removed from between the two connecting ears 30 and the leveling rod 34 is inserted into the through hole 39. At this time, two workers can drag the leveling device to move by the leveling rod 34, which reduces the work intensity of the workers and improves the leveling efficiency.

[0071] However, as is well known to those skilled in the art, the working principles and wiring methods of the vibrator 17 and the lighting lamp 40 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
