Description

Technical Field

[0001] The utility model relates to the technical field of automatic noodle-making machines, in particular to an automatic noodle-making machine with a slope. Background Art

[0002] The compaction of slope cushion materials and the construction of slope lining panels are critical steps in the construction of pumped-storage power station banks and other earth-rock dams. The quality of this construction directly impacts the quality of the reservoir's anti-seepage panels. After the lining is completed, the resulting slope surface requires leveling to ensure a smooth, even surface. Because slopes typically have steep gradients and construction often involves formwork and segmented construction, with a small single construction length and area, large-scale finishing equipment is unsuitable for movement and use. Therefore, the leveling and finishing of slope protection surfaces currently relies almost entirely on manual labor and small trowels. This is not only labor-intensive and inefficient, but also results in poor surface smoothness and difficulty in ensuring overall quality.

[0003] Chinese utility model patent publication number CN221345309U discloses a device for finishing cast-in-place layers on steep slopes. The device comprises a connecting portion connected to a roller via a bearing, and a powered operating arm hinged to the connecting portion. By utilizing the deadweight of its own structure, the device meets the weight requirements for repeated concrete finishing and troweling. Its high component rigidity effectively reduces tool deformation during use, and the low frictional resistance of the rolling trowel significantly improves finishing efficiency.

[0004] This solution mainly relies on the roller moving along the slope to roll the surface of the concrete slope protection to achieve smoothing of the slope surface. However, in this device, the device itself does not have the ability to drive and move the roller, and can only drag the roller to move for smoothing. Since the concrete used for the slope protection is to reduce landslides and collapses during pouring, the concrete used has high requirements on dryness and wetness. Moving on the surface in the form of pulling can easily cause cracks on the surface of the concrete slope protection, resulting in poor smoothing quality. Utility Model Content

[0005] In view of the deficiencies in the above-mentioned background technology, the present invention proposes an automatic slope finishing machine, which solves the problem of poor finishing quality in the prior art.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 creative work are within the scope of protection of the present invention.

[0022] like Figure 1 、 2 As shown in Example 1, an automatic noodle machine for sloped surfaces comprises a roller shaft 1, which provides support for the installation of auxiliary components. The roller shaft 1 is rotatably mounted at both ends on brackets 3, which are equipped with a height adjustment mechanism 2. Brackets 3 are also equipped with a driver that drives the roller shaft 1. In this embodiment, the driver utilizes a conventional drive motor 20. Several buffer mechanisms 4 are circumferentially and evenly spaced on the roller shaft 1. Each buffer mechanism 4 is connected to a smear 5. These buffer mechanisms maintain a certain leveling force, resulting in improved smoothing quality.

[0023] When this embodiment is in use, the optional bracket 3 is directly connected to the rear end of a conventional slipform trolley. As the slipform trolley moves to spread and vibrate the concrete, the paved concrete surface is simultaneously smoothed from the rear. When smoothing, the driver is turned on, and the driver drives the roller to rotate relative to the bracket, synchronously driving the trowel on the roller to rotate with the roller. As the trowels arranged circumferentially contact the concrete surface one by one and slide, smoothing the slope surface in a manner that simulates manual smoothing, avoiding the quality problems caused by the pulling and rolling method in the existing technology. During construction, by adjusting the height adjustment mechanism, the distance between the trowel and the concrete surface can be adjusted according to the actual scenario, and the smoothing pressure of the trowel applied by the buffer mechanism on the concrete surface can be adjusted to achieve better molding quality.

[0024] As a further optional solution, a roller 18 is provided under the bracket 3, and the roller is capable of cooperating with the track of the slipform trolley at the construction site, so that the noodle making machine is movably set on the track and moved by being pulled when the slipform trolley moves.

[0025] Example 2, based on Example 1, comprises two parallel beams 6 connected by telescopic columns 7. In this embodiment, a support bracket is fixed to one side of the upper beam, and a drive motor 20 is fixed to the bracket. The main shaft of the drive motor is connected to the roller shaft via a belt drive pair. As a further embodiment, the beams on both sides are connected by a connecting rod, thereby enhancing the structural stability and strength.

[0026] In addition, the height adjustment mechanism 2 includes a screw nut 8 fixed to one of the crossbeams 6. In this embodiment, the screw nut is welded to the crossbeam 6, and the screw nut 8 is threadedly connected to the screw 9. A through hole is provided on the other crossbeam 6 to accommodate the screw 9. The screw 9 passes through the other crossbeam 6 through the through hole, allowing the screw to slide relative to the other crossbeam 6. A stop cap 10 is fixed to the end of the screw 9, and a buffer spring is provided between the two crossbeams 6. In this embodiment, the buffer spring is disposed within the telescopic column. The telescopic column includes two outer tubes, which are nested between the ends and can slide relative to each other in the axial direction. The buffer spring is disposed between the two outer tubes, thereby contracting or expanding as the two outer tubes slide relative to each other. In addition, an adjustment lever 11 is slidably inserted into the stop cap 10. By grasping the adjustment lever, the stop cap can be rotated, thereby synchronously driving the screw to rotate.

[0027] In this embodiment, the two beams are arranged correspondingly above and below, and the screw nut is welded and fixed to the lower beam. Under normal conditions, the two beams are in a stretched state under the action of the buffer spring, and the lower end of the screw is threadedly connected to the screw nut. The lower surface of the stop cap fits the upper surface of the upper beam 6, and the roller shaft 1 is connected to the upper beam. When the height of the roller shaft needs to be adjusted, the screw is rotated by the adjusting lever. With the cooperation of the screw and the screw nut, the upper beam is pressed down through the stop cap and the buffer spring is compressed at the same time, or the stop cap is moved up, and the buffer spring is pushed up relative to the lower beam under the action of the expansion, thereby changing the height position of the roller shaft connected to the upper beam.

[0028] Example 3, based on Example 1, Figure 3 As shown, the roller shaft 1 comprises a central shaft 12, with a roller 13 coaxially fixed to the central shaft 12. The end of the central shaft 12 rotatably engages with a shaft seat 14 fixed to the upper crossbeam 6. The driver is fixed to a support bracket on one side of the upper crossbeam and is connected to the central shaft via a belt drive pair. Furthermore, in this embodiment, the shaft seat is fixed to the upper crossbeam and located between the two beams, making the structure more compact and space-efficient.

[0029] Furthermore, the buffer mechanism 4 includes mounting bars 15 fixedly mounted on the surface of the drum 13 at equal intervals around the circumference. Springs 16 are fixedly mounted on the mounting bars 15 at equal intervals and are fixedly connected to the wipers 5 via the springs 16. In this embodiment, six mounting bars are provided, welded to the drum surface. The springs 16 are welded to the mounting bars, and each wiper 5 is fixedly connected to two springs.

[0030] As a further embodiment, the trowel 5 is an arc-shaped piece, and a connecting block 17 is fixedly provided on the inner side of the arc-shaped piece, and the connecting block 17 is fixedly connected to the spring 16. The arc-shaped piece can better cooperate with the rotation of the roller to achieve sliding contact with the concrete surface for smoothing, avoiding scraping of the concrete when contacting the concrete surface, which affects the quality.

[0031] In this embodiment, Figure 4 As shown, a gap is left between the curved pieces connected to the same mounting bar 15. The gap width is smaller than the axial length of the curved piece. The curved pieces on adjacent mounting bars 15 are staggered and overlap only at their ends. This ensures that the unsmoothed area left in the gap by the curved piece on the previous mounting bar when it contacts and smoothes the concrete surface can be smoothed by the curved piece on the next mounting bar, which is more in line with the actual manual smoothing operation. At the same time, the provision of gaps can reduce the area that the curved pieces on the same mounting bar need to smooth simultaneously, avoiding the situation where a large area is smoothed in a single pass, and the reaction force generated by the concrete surface is too large, causing the smoothing machine to vibrate and affect the quality.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
