However, the smoothing device in this patent still has the following problems: 1. In order to replace the matching trowel plate for concrete of different widths, the smoothing device needs to be disassembled and reinstalled, which reduces the working efficiency; 2. Due to the uneven thickness of the accumulated concrete after pouring, the concrete cannot be fully leveled by just pushing the concrete with a push plate. Utility Model Content

[0004] In view of the above problems, the purpose of the present utility model is to provide a leveling device for civil engineering construction to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a smoothing device for civil construction, including a mobile vehicle with rollers at the bottom, a first electric telescopic rod arranged between the mobile vehicle and the rollers, and a smoothing device arranged at the bottom of the mobile vehicle, the smoothing device including an arc-shaped rake arranged on one side of the mobile vehicle and detachably connected to the bottom of the mobile vehicle, a push plate detachably connected to the middle part of the bottom of the mobile vehicle and used for leveling concrete, a first trowel plate arranged on the side of the mobile vehicle away from the rake through the second electric telescopic rod, and a second trowel plate symmetrically arranged on both sides of the trowel plate and connected to the mobile vehicle through an adjustment component.

[0006] The beneficial effects of the utility model are as follows: by arranging a rake, a push plate, a rotating roller and a trowel plate with adjustable length, concrete of uneven thickness can be fully leveled and then smoothed; at the same time, the length of the trowel plate can be easily increased, making it suitable for concrete surfaces with larger widths, without the need to repeatedly disassemble and replace the trowel plate.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0031] like Figure 1-4As shown, a trowel device for civil engineering construction comprises a mobile vehicle 2 with a roller 1 at the bottom, a first electric telescopic rod 3 arranged between the mobile vehicle 2 and the roller 1, and a trowel device arranged at the bottom of the mobile vehicle 2, wherein the trowel device comprises an arc-shaped rake 4 arranged at one side of the mobile vehicle 2 and detachably connected to the bottom of the mobile vehicle 2, a push plate 5 detachably connected to the middle part of the bottom of the mobile vehicle 2 and used for troweling concrete, a first trowel plate 7 arranged at a side of the mobile vehicle 2 away from the rake 4 through a second electric telescopic rod 6, and a second trowel plate 8 symmetrically arranged at both sides of the trowel plate and connected to the mobile vehicle 2 through an adjustment component. By arranging the rake 4, the push plate 5, the rotating roller 23 and the trowel plate with adjustable length, the uneven thickness of concrete can be smoothed. The trowel 7 is smoothed and leveled fully, and then smoothed. At the same time, it is also convenient to increase the length of the trowel plate, so that it is suitable for concrete surfaces with a larger width, and there is no need to repeatedly disassemble and replace the trowel plate. The adjustment component includes a mounting groove 9 opened at the bottom of the mobile vehicle 2, a motor 10 arranged at one end of the mounting groove 9, a bidirectional threaded rod 11 arranged on the output shaft of the motor 10, sliders 12 symmetrically arranged on both sides of the bidirectional threaded rod 11, a support rod 13 arranged on the side of the slider 12 away from the first trowel plate 7, and a hanger 14 symmetrically arranged on both sides of the support rod 13 and connected to the second trowel plate 8 at its bottom end. When the length of the second trowel plate 8 needs to be extended, the bidirectional threaded rod 11 is driven to rotate by the motor 10, and the two sliders 12 are driven to move away from the center of the bidirectional threaded rod 11 One side slides, driving the support rod 13, the suspension rod 14 and the second trowel plate 8 to move to the side away from the first trowel plate 7, and then the first trowel plate 7 is driven to move by the second electric telescopic rod 6 so that the first trowel plate 7 and the second trowel plate 8 are flush. The two second trowel plates 8 are both arranged at the bottom of the first trowel plate 7, and the first trowel plate 7 and the second trowel plate 8 have the same thickness. When the length of the first trowel plate 7 is extended, the second trowel plate 8 is driven to move downward by the second electric telescopic rod 6 until the first trowel plate 7 and the second trowel plate 8 are flush, so that the first trowel plate 7 and the second trowel plate 8 can better smooth the concrete. The two ends of the first trowel plate 7 are symmetrically provided with limit clamps 15, and the two second trowel plates 8 are close to each other. The near side is provided with a slot 16 adapted to the limit card plate 15. When the bidirectional threaded rod 11 drives the second wiping plate 8 to move to the limit card plate 15 and align with the slot 16 on the first wiping plate 7, the second electric telescopic rod 6 drives the first wiping plate 7 to move downward, and drives the limit card plate 15 to be stuck in the slot 16, so that the first wiping plate 7 can be moved to a state flush with the second wiping plate 8. The bottom of the mobile vehicle 2 and above the rake 4 and the push plate 5 are provided with a hanging plate 18 with a slot 17. The top of the rake 4 and the push plate 5 are provided with a plug plate 19 adapted to the slot 17. The plug plate 19 is connected to the hanging plate 18 by bolts 20. When installing the rake 4 and the push plate 5, the plug plates 19 on the rake 4 and the push plate 5 are tightened.Inserted into the two hanging plates 18 at the bottom of the mobile vehicle 2 respectively, the plug plate 19 is connected to the hanging plate 18 with bolts 20, the end of the push plate 5 away from the rake 4 is connected to a fixed shaft 22 through a support frame 21, and the outer wall of the fixed shaft 22 is rotatably connected to a roller 23 for assisting the push plate 5 to flatten the concrete, and the bottom end of the roller 23 is flush with the bottom end of the push plate 5. When the rake 4 and the push plate 5 flatten the concrete, the roller 23 is driven to rotate along the concrete to flatten the concrete and improve the flatness of the concrete. The push plate 5 is provided with an arc-shaped slope 24 on the side close to the rake 4. By providing the arc-shaped slope 24 on the push plate 5, it is easy to push the concrete to make its surface initially flat, prevent concrete accumulation, and the arc surface is subject to little resistance.

[0032] The working principle and use process of the utility model are as follows: when using the device, the device is first moved to a designated position by the roller 13, and the height of the mobile vehicle 2 can be adjusted by the extension and retraction of the first electric telescopic rod 3, and then the height of the rake 4, the push plate 5, the roller 23 and the second flat plate 8 are adjusted to make them contact with the concrete surface. As the mobile vehicle 2 moves, the rake 4 first spreads and spreads the concrete with uneven thickness, and then flattens it through the push plate 5, and then as the roller 23 rotates on the concrete surface, the particles on the concrete surface are compacted again, so that the concrete can be fully leveled, and finally the second flat plate 8 flattens the concrete. When it is necessary to smooth the surface of a concrete surface with a larger width, the motor 10 drives the two-way threaded rod 11 to rotate, driving the two sliders 12 to slide to the side away from the center of the two-way threaded rod 11, driving the support rod 13, the suspension rod 14 and the second wiping plate 8 to move to the side away from the first wiping plate 7. When the second wiping plate 8 moves to the limiting card plate 15 and is aligned with the slot 16 on the first wiping plate 7, the second electric telescopic rod 6 drives the first wiping plate 7 to move downward, and when driving the limiting card plate 15 to be stuck in the slot 16, the first wiping plate 7 is aligned with the second wiping plate 8, thereby increasing the length of the second wiping plate 8.
