Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a concrete floor slab curing device. Background Art

[0002] When the concrete floor is being maintained, workers need to lay plastic film on the concrete floor. When the plastic film is wrapped on the concrete floor, it can reduce the evaporation rate of water in the concrete and prevent the concrete from drying out prematurely. After the plastic film is laid on the concrete floor, workers need to spray water on the plastic film. When the concrete floor is firmly formed, workers need to tear off the plastic film on the concrete floor. The common way to tear off plastic film on the market is for construction workers to use rakes or palms to tear off the plastic film on the concrete floor. This method can indeed achieve a good tearing effect on the plastic film on the concrete floor, but in actual use, there are still some shortcomings:

[0003] 1. When using a rake or palm to tear off the plastic film on the concrete floor, it is easy to cause the plastic film to be damaged. The damaged plastic film is not easy to clean and transport. It is also easy to cause the damaged plastic film to adhere to the concrete floor, which is inconvenient for the staff to maintain the concrete floor later.

[0004] 2. When the plastic film is wrapped on the concrete floor, concrete is likely to adhere to the plastic film, which will solidify into concrete blocks. When the construction workers tear off the plastic film wrapped on the concrete floor, the concrete on the plastic film is likely to splash. The splashed concrete will not only pollute the concrete floor, but also easily scratch the construction workers.

[0005] 3. When the plastic film is wrapped on the concrete floor, bubbles will exist between the concrete floor and the plastic film. These bubbles will affect the maintenance effect of the plastic film on the concrete floor and may easily cause damage to the plastic film.

[0006] To this end, we propose a concrete floor curing device. Summary of the Invention

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figure 1-6 , the present invention provides a technical solution:

[0040] The concrete floor curing device includes a support structure 3 and a first conveying structure 1 and a second conveying structure 2 distributed on the support structure 3. The first conveying structure 1 and the second conveying structure 2 can drive the plastic film on the concrete floor to separate from the concrete floor. The device also includes:

[0041] Abutment structure 4, which is distributed at the collecting ends of the first conveying structure 1 and the second conveying structure 2. The abutment structure 4 can abut against the plastic film covering the concrete floor. A water spray pipe 6 is distributed above the first conveying structure 1 and the second conveying structure 2. The water spray pipe 6 can spray water on the plastic film abutted by the abutment structure 4. The pushing structure 5 is fixedly connected to the water spray pipe 6.

[0042] During the actual use of the maintenance device, the worker can push the structure 5 to drive the water spray pipe 6 to move forward and backward, and then the water receiving end of the water spray pipe 6 is connected to the external pump to spray water on the concrete floor;

[0043] Example 2: Please refer to Figure 1 、 2 , 4-6, 9-11, the present invention provides a technical solution:

[0044] The abutment structure 4 includes a rolling column 41 and an elastic strip 45 fixedly connected to the rolling column 41. The rolling column 41 can cooperate with the elastic strip 45 to form a sealed cylindrical cavity structure. The two ends of the rolling column 41 are fixedly connected to a rotating tube 44, and the rotating tube 44 is rotatably connected to the push plate 42.

[0045] When air is injected into the rolling column 41, the elastic strip 45 can be squeezed and expanded. At this time, the elastic strip 45 can cooperate with the rolling column 41 to form a smooth columnar cavity structure, so that the rolling column 41 can drive the elastic strip 45 to roll the plastic film on the surface of the concrete floor, thereby avoiding the accumulation of air between the concrete floor and the plastic film. When the air inside the rolling column 41 is discharged, the elastic strip 45 is no longer squeezed. At this time, the elastic strip 45 and the rolling column 41 form a rough columnar cavity structure. When the rolling column 41 rotates, it can cooperate with the elastic strip 45 to drive the plastic film to rise, thereby realizing the separation of the plastic film from the concrete floor.

[0046] Example 3: Please refer to Figure 1-5 , the present invention provides a technical solution:

[0047] The first conveying structure 1 and the second conveying structure 2 have the same structure. A second push wheel 11 and a first push wheel 9 are distributed on the first conveying structure 1 and the second conveying structure 2. The first push wheel 9 and the second push wheel 11 have the same structure. The second push wheel 11 includes a push wheel structure 111 and an elastic sheet 117 fixedly connected to the push wheel structure 111. The push wheel structure 111 and the elastic sheet 117 can also form a sealed cylindrical cavity structure.

[0048] The push wheel structure 111 is also fixedly connected to a rotating tube 44. The rotating tube 44 on the push wheel structure 111 penetrates the support structure 3, so that the push wheel structure 111 can rotate on the support structure 3. The rotating tube 44 on the push wheel structure 111 is fixedly connected to an end air cap 113. The end air cap 113 is fixedly connected to a connecting tube 114. The end of the connecting tube 114 facing away from the end air cap 113 is fixedly connected to an extrusion air bag 112.

[0049] When the extrusion airbag 112 is squeezed, the air inside the extrusion airbag 112 can enter the interior of the push wheel structure 111 through the connecting tube 114. When the elastic sheet 117 is squeezed and expanded, the elastic sheet 117 can form a smooth cylindrical cavity structure with the push wheel structure 111, which can prevent the second push wheel 11 and the first push wheel 9 from damaging the plastic film. When the elastic sheet 117 resets, the elastic sheet 117 can shrink. At this time, the surfaces of the second push wheel 11 and the first push wheel 9 are concave, which can increase the friction between the second push wheel 11 and the first push wheel 9 and the ground.

[0050] Example 4: Please refer to Figure 1-6 10. The present invention provides a technical solution:

[0051] The second conveying structure 2 includes a belt structure 25, an adhesive strip 24 is distributed on the outside of the belt structure 25, a pressure strip 21 is distributed on the inside of the belt structure 25, a plug-in strip 23 is fixedly connected between the adhesive strip 24 and the pressure strip 21, the plug-in strip 23 passes through the belt structure 25, and a connecting spring 22 is fixedly connected between the pressure strip 21 and the belt structure 25.

[0052] A driving structure 12 is provided at the end of the inner side of the belt structure 25. The driving structure 12 includes a second roller 125 and a first roller 123. The outer walls of the second roller 125 and the first roller 123 are in contact with the inner wall of the belt structure 25. Both ends of the second roller 125 are fixedly connected to a transmission end column 127, and a transmission gear 121 is fixedly connected to the transmission end column 127. Both ends of the first roller 123 are fixedly connected to a pressure gear 124, and the transmission gear 121 and the pressure gear 124 are engaged.

[0053] The inner sides of the pressing gear 124 and the transmission gear 121 do not abut against the belt structure 25. A swing rod 128 is sleeved on the transmission end column 127 between the transmission gear 121 and the second roller 125. A plug rod 129 is inserted into the end of the swing rod 128 facing away from the transmission end column 127. The plug rod 129 is fixedly connected to the water spray pipe 6.

[0054] When the second roller 125 and the first roller 123 rotate, the second roller 125 and the first roller 123 can drive the belt structure 25 to rotate. At this time, the adhesive strip 24 on the belt structure 25 can also move. When the adhesive strip 24 contacts the plastic film, the adhesive strip 24 can drive the plastic film to pass to the water pipe 6, so that the plastic film can be quickly separated from the concrete floor.

[0055] Example 5: Please refer to Figure 1-5 , the present invention provides a technical solution:

[0056] One side of the transmission end column 127 and the first roller 123 is sleeved with an outer cover 130, and the other side of the transmission end column 127 and the first roller 123 is sleeved with an inner cover 122, and a connecting frame 126 is fixedly connected between the outer cover 130 and the inner cover 122, and the outer cover 130 is connected between the push plate 42 and the bracket structure 3, and a return spring 46 is connected between the push plate 42 and the outer cover 130, and the return spring 46 can drive the flipping angle of the push plate 42 to reset. A top pressure structure 7 is distributed on the connecting frame 126, and the top pressure structure 7 includes an inclined bottom plate 71 distributed above the water spray pipe 6, and the bottom of the inclined bottom plate 71 is fixedly connected to a sliding rod 73, which penetrates the connecting frame 126, and the lower end of the sliding rod 73 is fixedly connected to an abutting cylinder 74, and the sliding rod 73 is fixedly connected to an abutting spring 72 between the abutting cylinder 74 and the connecting frame 126.

[0057] The outer cover 130 is provided with a sliding groove 116. The squeezing airbag 112 is fixedly connected to the outer cover 130 below the sliding groove 116. The outer cover 130 is slidably connected to the sliding groove 116 with a squeezing rod 115. The squeezing rod 115 can squeeze the squeezing airbag 112. The squeezing rod 115 is fixedly connected to the water spray pipe 6.

[0058] When the second roller 125 and the first roller 123 in the maintenance device rotate, the transmission gear 121 can squeeze the abutment cylinder 74. At this time, the sliding rod 73 can drive the inclined bottom plate 71 to move upward. At the same time, the abutment spring 72 is compressed, and the inclined bottom plate 71 can pull the plastic film, so that the plastic film can be moved obliquely backward. At this time, the inclined bottom plate 71 can cooperate with the abutment structure 4 to move the plastic film. When the transmission gear 121 does not squeeze the abutment cylinder 74, the abutment spring 72 can drive the abutment cylinder 74 to reset, so that the abutment cylinder 74 can abut on the transmission gear 121.

[0059] Example 6: Please refer to Figure 1-6 , the present invention provides a technical solution:

[0060] An air guide tube 43 is fixedly connected to the push plate 42, and an air collecting structure 8 abuts against the air guide tube 43. The inner cavities of the air guide tube 43 and the push plate 42 are connected to the inner cavity of the rotating tube 44. A fixing rod 82 is fixedly connected to the air collecting structure 8, and the air collecting structure 8 is fixedly connected to the water spray pipe 6 via the fixing rod 82. The air collecting structure 8 is a hollow structure. A first valve 81, a second valve 83, and a limit rod 84 are distributed near the air guide tube 43 of the air collecting structure 8. The inner cavity of the air collecting structure 8 is connected to the inner cavity of the air guide tube 43 by the first valve 81 and the second valve 83.

[0061] When the staff's hand drives the water spray pipe 6 forward by pushing the structure 5, the bottom of the air collecting structure 8 can slide on the air guide pipe 43. At this time, the upper end of the air guide pipe 43 abuts against the second valve 83. The air inside the air collecting structure 8 can be transported to the inside of the air guide pipe 43 through the second valve 83. At this time, the elastic strip 45 can be squeezed and expanded. At this time, the elastic strip 45 can cooperate with the rolling column 41 to form a smooth columnar cavity structure, which can realize that the rolling column 41 drives the elastic strip 45 to roll the plastic film on the surface of the concrete floor. Pressure, when the pushing structure 5 drives the water spray pipe 6 to move backward, the bottom of the air collecting structure 8 can slide on the air guide pipe 43, and the upper end of the air guide pipe 43 is in contact with the first valve 81. At this time, the first valve 81 is opened to work, and the air inside the rolling column 41 will flow back to the inside of the air collecting structure 8 through the first valve 81. When in use, the limiting rod 84 can limit the sliding position of the air guide pipe 43. At the same time, when the air guide pipe 43 is not in contact with the first valve 81 and the second valve 83, the first valve 81 and the second valve 83 are closed to work.

[0062] Example 7: Please refer to Figure 1-6 , the present invention provides a technical solution:

[0063] A transmission rod 101 is fixedly connected between the two second push wheels 11, and a transmission rod 101 is also fixedly connected between the two first push wheels 9. One end of the transmission end column 127 is located on the outside of the inner cover 122 and is sleeved with a ratchet structure 13. A ratchet structure 13 is also sleeved on the transmission rod 101, and a connecting belt 10 is sleeved between the ratchet structure 13 on the transmission end column 127 and the ratchet structure 13 on the transmission rod 101.

[0064] The ratchet structure 13 includes a sleeve wheel 134 sleeved on the transmission rod 101 and the transmission end column 127. The edge of the sleeve wheel 134 is provided with an abutting notch 135. The sleeve wheel 134 is abutted against a limiting tooth 132 inside the abutting notch 135. The sleeve wheel 134 is sleeved with a rotating wheel 131. The limiting tooth 132 is rotatably connected to the inside of the rotating wheel 131. An extrusion spring 136 is fixedly connected between the limiting tooth 132 and the rotating wheel 131. Pulling teeth 133 are fixedly connected to the outer wall of the rotating wheel 131 at equal intervals. The rotating wheel 131 is connected to the connecting belt 10 via the pulling teeth 133.

[0065] When the first push wheel 9 and the second push wheel 11 move in the forward direction, the ratchet structure 13 on the transmission rod 101 can drive the ratchet structure 13 on the transmission end column 127 to rotate forward through the connecting belt 10. At this time, the connecting belt 10 can drive the limiting tooth 132 to push the socket wheel 134 through the pulling tooth 133, so that the second roller 125 can drive the belt structure 25 to rotate. When the first push wheel 9 and the second push wheel 11 move in the reverse direction, the ratchet structure 13 on the transmission rod 101 can drive the ratchet structure 13 on the transmission end column 127 to rotate in the reverse direction through the connecting belt 10. At this time, the connecting belt 10 can drive the limiting tooth 132 not to push the socket wheel 134 through the pulling tooth 133.
