It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other arbitrarily without conflict.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 An embodiment of the present invention is shown, in which a roof leveling device for building construction is disclosed, including two support seats 1, and the two support seats 1 are used to be fixed on both sides of the roof, a support frame 2 is horizontally arranged between the two support seats 1, and the two ends of the support frame 2 are respectively connected to the corresponding support seats 1.

[0022] like Figure 1 , Figure 2 As shown, the bottom of the support frame 2 is horizontally slidably connected to the receiving frame 3, and the forward direction of the receiving frame 3 is parallel to the length direction of the support frame 2. At the same time, a driving member 4 is provided on the receiving frame 3 and the support frame 2, and the driving member 4 is used to control the horizontal movement of the receiving frame 3.

[0023] like Figure 1 , Figure 2As shown, the bottom of the receiving frame 3 is provided with a scraping mechanism 5, a compacting mechanism 6 and a smoothing mechanism 7 from front to back. The scraping mechanism 5 is used to scrape off excess mortar from the mortar layer, the compacting mechanism 6 is used to compact the mortar layer, and the smoothing mechanism 7 is used to smooth the surface of the mortar layer to ensure the aesthetics of the roof.

[0024] When the roof needs to be leveled, two support seats 1 are fixed on both sides of the roof, and the support seats 1 are leveled, and then the two ends of the support frame 2 are respectively connected to the corresponding support seats 1, and the level of the support frame 2 is detected by a level meter. Subsequently, the receiving frame 3 is controlled to move forward intermittently through the driving member 4. During this process, the scraping mechanism 5 scrapes off the excess mortar of the mortar layer, the compacting mechanism 6 compacts the mortar layer, and the smoothing mechanism 7 smoothes the surface of the mortar layer, thereby achieving the leveling operation.

[0025] The roof leveling device for house construction in this embodiment can realize semi-automatic leveling operation of the roof. Compared with manual plastering operation by workers, it can not only reduce the burden on workers, but also improve the flatness of the roof, thereby ensuring the construction quality.

[0026] like Figure 2 , Figure 3 As shown, the scraping mechanism 5 includes a scraping plate 51 vertically fixed to the bottom of the receiving frame 3, and one end of the scraping plate 51 is tilted backward so that the scraping plate 51 can scrape and push away excess mortar from the mortar layer to avoid mortar accumulation in front of the scraping plate 51, so as to ensure the mortar scraping effect.

[0027] like Figure 2 , Figure 3 As shown, the scraping mechanism 5 also includes a scraping roller 52 horizontally rotatably connected to the bottom of the receiving frame 3, the scraping roller 52 is located behind the scraping plate 51, and the lowest point of the outer surface of the scraping roller 52 is lower than the lower surface of the scraping plate 51. The rotation axis of the scraping roller 52 is perpendicular to the movement direction of the receiving frame 3, and a control member 8 is provided on the support frame 2 and the scraping roller 52, and the control member 8 is used to control the rotation of the scraping plate 51.

[0028] like Figure 2 , Figure 3 As shown, the control member 8 includes a control gear 81 and a control rack 82. The control rack 82 is fixed on the support frame 2, and the length direction of the control rack 82 is parallel to the movement direction of the receiving frame 3. The control gear 81 is fixedly mounted on the rotating shaft of the scraper roller 52, and the control gear 81 is meshed with the control rack 82.

[0029] When the receiving frame 3 moves forward, the scraping roller 52 automatically rotates under the action of the control gear 81 and the control rack 82, and performs compaction and scraping operations on the mortar layer. Since the lowest point of the outer surface of the scraping roller 52 is lower than the lower surface of the scraping plate 51, that is, the scraping plate 51 first scrapes off a part of the excess mortar in the mortar layer, and then the scraping roller 52 compacts the mortar layer and scrapes off the excess mortar. Using the scraping plate 51 and the scraping roller 52 to scrape the mortar twice has a better scraping effect and can also achieve compaction of the mortar layer.

[0030] like Figure 2 , Figure 3 As shown, the driving member 4 adopts a travel motor 41, and a travel gear 42 is fixedly sleeved on the output shaft of the travel motor 41, and the travel gear 42 is meshed with the control rack 82, so that after the travel motor 41 is started, the receiving frame 3 can automatically move forward. At the same time, the travel gear 42 and the control gear 81 can share the control rack 82 to improve resource utilization efficiency.

[0031] like Figure 1 , Figure 2 As shown, the compacting mechanism 6 includes a first compacting plate 61 and a second compacting plate 62 which are horizontally arranged. The first compacting plate 61 and the second compacting plate 62 are respectively horizontally slidably connected to the bottom of the receiving frame 3, and the lower surfaces of the first compacting plate 61 and the second compacting plate 62 are flush and respectively lower than the lowest point of the outer surface of the scraper roller 52.

[0032] like Figure 2 , Figure 3 As shown, the length direction of the first compacting plate 61 is perpendicular to the movement direction of the receiving frame 3 , the movement direction of the first compacting plate 61 is parallel to the movement direction of the receiving frame 3 , and the receiving frame 3 is provided with a first pipe control unit 9 for controlling the horizontal reciprocating motion of the first compacting plate 61 .

[0033] like Figure 2 , Figure 3 As shown, the second compacting plate 62 is located behind the first compacting plate 61, the length direction of the second compacting plate 62 is parallel to the movement direction of the receiving frame 3, the movement direction of the second compacting plate 62 is perpendicular to the movement direction of the receiving frame 3, and the receiving frame 3 is provided with a second tube control 10 for controlling the horizontal reciprocating movement of the second compacting plate 62.

[0034] The first compacting plate 61 is controlled to move horizontally and reciprocatingly by the first pipe control 9, and the second compacting plate 62 is controlled to move horizontally and reciprocatingly by the second pipe control 10, so as to realize the compaction and leveling operation of the mortar layer. Since there are some bubbles in the concrete mortar layer, the mortar layer is compacted by the first compacting plate 61 and the second compacting plate 62 in succession, which is conducive to the smooth discharge of bubbles in the concrete mortar layer, thereby ensuring the compactness of the mortar layer. At the same time, the movement directions of the first compacting plate 61 and the second compacting plate 62 are perpendicular, so as to realize the compaction and leveling operation of the mortar layer in two directions, which can not only ensure the compactness of the mortar layer, but also improve the flatness of the roof.

[0035] like Figure 2 , Figure 3 As shown, the first tube control unit 9 includes a first double-drive screw 91 and a first drive motor 92. Both ends of the first double-drive screw 91 are rotatably connected to the receiving frame 3 respectively, and the first double-drive screw 91 passes through the first compacting plate 61 and is threadedly connected to the first compacting plate 61. The first drive motor 92 is fixed on the receiving frame 3, and the output shaft of the first drive motor 92 is coaxially fixedly connected to the first double-drive screw 91, so that the first compacting plate 61 can reciprocate smoothly.

[0036] like Figure 2 , Figure 3 As shown, the second tube control unit 10 includes a second dual-drive screw 101 and a second drive motor 102. Both ends of the second dual-drive screw 101 are rotatably connected to the receiving frame 3, and the second dual-drive screw 101 passes through the second compacting plate 62 and is threadedly connected to the second compacting plate 62. The second drive motor 102 is fixed on the receiving frame 3, and the output shaft of the second drive motor 102 is coaxially fixedly connected to the second dual-drive screw 101, so that the second compacting plate 62 can reciprocate smoothly.

[0037] like Figure 1 , Figure 2 As shown, the trowel mechanism 7 includes a trowel plate 71 horizontally fixed to the bottom of the receiving frame 3, the length direction of the trowel plate 71 is perpendicular to the movement direction of the receiving frame 3, and the lower surface of the trowel plate 71 is flush with the lower surfaces of the first compaction plate 61 and the second compaction plate 62, so that the trowel plate 71 can perform trowel processing on the mortar layer.

[0038] like Figure 1 , Figure 2As shown, a spray pipe 72 is horizontally fixedly connected to the bottom of the receiving frame 3. The spray pipe 72 is located in front of the trowel plate 71, and the length direction of the spray pipe 72 is perpendicular to the movement direction of the receiving frame 3. A plurality of atomizing nozzles 73 are fixedly connected to the lower end of the spray pipe 72. The plurality of atomizing nozzles 73 are arranged at equal intervals along the length direction of the spray pipe 72, and the atomizing nozzles 73 are used to spray water mist on the surface of the mortar layer. A water storage tank 74 is fixedly connected to the receiving frame 3. The water storage tank 74 is connected to the spray pipe 72 through a water inlet pipe 75. A booster pump is arranged in the water storage tank 74, and the booster pump is connected to the water inlet pipe 75.

[0039] The clean water in the water tank 74 is pumped into the spray pipe 72 through a booster pump, and the clean water is sprayed out through multiple atomizing nozzles 73 so that the water mist is sprayed on the surface of the mortar layer to promote the flow effect of the concrete slurry on the surface of the mortar layer. When the trowel plate 71 passes through this position, the trowel plate 71 can promote the movement of the concrete slurry and fill the holes on the surface of the mortar layer to improve the flatness and aesthetics of the roof.

[0040] like Figure 2 , Figure 4 As shown, guide seats 11 are fixedly connected to both ends of the support frame 2, and guide rails 12 are vertically fixedly connected to the two support seats 1. The two guide seats 11 are vertically slidably matched with the corresponding guide rails 12, and each guide rail 12 and the corresponding guide seat 11 are respectively provided with a locking piece 13, which is used to fix the corresponding guide seat 11.

[0041] Since the height of the support plate can be adjusted, the height of the scraper plate 51, the scraper roller 52, the first compacting plate 61 and the second compacting plate 62 can be adjusted, so as to adapt to the leveling operation of roofs of different thicknesses, so as to improve the adaptability of the roof leveling device. It should be noted that the height adjustment of the support frame 2 is based on the height of the lower surface of the first compacting plate 61, the second compacting plate 62 and the trowel plate 71.

[0042] like Figure 2 , Figure 4 As shown, the locking member 13 includes a locking screw 131 threadedly connected to the guide seat 11, and a plurality of locking grooves 132 are arranged on the guide rail 12. The plurality of locking grooves 132 are arranged at equal intervals in the vertical direction, and the locking screw 131 can be threadedly matched with any locking groove 132, thereby realizing rapid locking of the guide seat 11, thereby realizing rapid adjustment of the height of the support frame 2.

[0043] As can be seen from the above, the use of the roof leveling device can realize the semi-automatic leveling operation of the roof, which can not only reduce the burden of the staff, but also improve the flatness of the roof, thereby ensuring the construction quality, compared with the manual plastering operation by the staff. At the same time, the mortar layer is compacted and leveled twice by using the first compacting plate 61 and the second compacting plate 62, and the movement directions of the first compacting plate 61 and the second compacting plate 62 are perpendicular, which can effectively improve the compactness of the mortar layer and the flatness of the roof, thereby ensuring the construction quality.
