Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, and in particular to a device for laying anti-pollution plastic film on curb stones. Background Technology

[0002] In urban road construction, curbs serve as important boundary demarcation facilities, and their aesthetics after construction directly affect the overall image of the road. However, during the application of tack coat and primer coat, curbs are highly susceptible to contamination by asphalt materials.

[0003] Traditional methods of manually laying plastic film for protection have significant shortcomings: not only is the construction efficiency low (requiring a large amount of labor to lay it section by section), but it also affects the project schedule. Moreover, ordinary plastic film is only 0.012mm-0.18mm thick, and the common method of having two people directly stretch and spread it is prone to overstretching, causing the plastic film to tear; or not fully unfolding it, resulting in folding and waste. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the present invention provides a device for laying anti-pollution plastic film on curb stones.

[0005] The present invention provides a curbstone anti-pollution plastic film laying device with the following technical solution: A device for laying anti-pollution plastic film on curb stones includes a main frame, which includes a crossbeam and vertical beams fixed to both ends of the crossbeam. A handrail, a mounting frame, and a connecting frame are installed on the crossbeam. A top roller for laying plastic film on the top surface of the curb stone is rotatably installed on the mounting frame. A roll of plastic film located in front of the main frame is installed on the connecting frame. A limit frame and a brush are installed on the vertical beam. A side roller for rolling contact with the side wall of the curb stone is rotatably installed on the limit frame. The top of the brush is inclined towards the forward direction, and the bottom of the brush is inclined away from the forward direction.

[0006] By adopting the above technical solutions, the curbstone anti-pollution plastic film laying device of this utility model achieves a dual improvement in construction efficiency and quality through mechanized design. It employs guide wheel sets and an adjustable film pressing mechanism to ensure neat and straight plastic film laying, effectively solving the problems of wrinkles or damage caused by traditional manual laying, reducing material waste by more than 50%. Only one person is needed to automatically unroll, press, and fix the film, increasing construction efficiency by 3 times compared to manual labor and reducing labor costs by 60%. A brush and top rollers are used to lay the plastic film on the curbstone after watering or adhesive application, ensuring a tight bond between the film and the curbstone surface, improving wind resistance and preventing detachment. This protects the curbstone throughout the entire process until the asphalt pavement layer is completed and the film is removed. The device is also adaptable to curbstones of different heights and widths, balancing construction quality and economy.

[0018] The following combination Figures 1-3 The present invention will be described in further detail below.

[0019] This utility model discloses a device for laying anti-pollution plastic film on curbs. The device includes a main frame 1, a handrail 2, a mounting frame 3, a top roller 4, a connecting frame 5, a plastic film roll 6, a limiting frame 7, side rollers 8, and a brush 9.

[0020] The main frame 1 is in the shape of an inverted U and is welded from angle steel. The main frame 1 includes a crossbeam 11 and two vertical beams 12 that are vertically fixed to the left and right ends of the crossbeam 11. The handrail 2 is inclined upward and fixed to the middle of the crossbeam 11 for the operator to use when pushing the device forward. The mounting frame 3 includes two vertical rods 31 that are vertically fixed to the bottom of the crossbeam 11. A horizontal rod 32 is horizontally fixed between the bottom ends of the two vertical rods 31. The top roller 4 is rotatably sleeved on the horizontal rod 32. The length of the top roller 4 is not less than the width of the top surface of the curb. The top roller 4 is a rubber wheel.

[0021] The connecting frame 5 includes a connecting rod 51 that rotatably passes through two vertical beams 12. The connecting rod 51 is perpendicular to the vertical beams 12. A protrusion is welded to the connecting rod 51 near the vertical beams 12 to restrict the axial movement of the connecting rod 51 and allow only the connecting rod 51 to rotate. L-shaped inserts 52 are fixed to both ends of the connecting rod 51. A torsion spring 53 is sleeved in the middle of the connecting rod 51. One leg of the torsion spring 53 is welded to the connecting rod 51, and the other leg of the torsion spring 53 is welded to the crossbeam 11. The torsion spring 53 has an elastic tendency to cause the two L-shaped inserts 52 to flip downward.

[0022] The plastic film roll 6 is detachably installed between the two L-shaped inserts 52. The plastic film roll 6 rolls in contact with the top surface of the curbstone, so that the plastic film is laid on the top surface of the curbstone. Under the elastic drive of the torsion spring 53, the plastic film roll 6 is always in contact with the top surface of the curbstone. The limiting frame 7 includes a sleeve 71 vertically fixed to the side wall of the vertical beam 12. A vertical tube 72 is slidably inserted inside the sleeve 71. Two clamps 73 distributed vertically are vertically fixed to the bottom end of the vertical tube 72. The clamps 73 are inclined towards the forward direction. The side rollers 8 are rotatably installed between the ends of the two clamps 73 away from the vertical tube 72.

[0023] To facilitate adjustment of the spatial height of the side roller 8 according to the exposed height of the curbstone, the vertical tube 72 is provided with multiple rows of limiting holes 721, and the sleeve 71 is threaded with limiting screws 74 for inserting into the limiting holes 721. The spatial height and rotation angle of the vertical tube 72 are determined by the limiting screws 74, which not only controls the spatial height of the side roller 8, but also controls the horizontal position of the side roller 8 to adapt to curbstones of different widths, so that the side roller 8 can effectively roll and contact the side of the curbstone.

[0024] The brush 9 is tilted, with the top of the brush 9 tilted towards the direction of travel and the bottom of the brush 9 tilted away from the direction of travel. A support rod 91 is horizontally fixed to the middle of the brush 9, and the support rod 91 is vertically fixed to the inner wall of the vertical beam 12. The brush 9 is used to brush the plastic film so that the plastic film is evenly attached to the surface of the curb. The softness of the brush bristles of the brush 9 makes it suitable for curbs of different widths.

[0025] The implementation principle of the curb anti-pollution plastic film laying device of this utility model embodiment is as follows: The operator first adjusts the spatial height and horizontal position of the side roller 8 according to the width and exposed height of the curb, so that the side roller 8 can effectively contact the outer wall of the curb. Then, water is sprinkled or double-sided tape is pasted on the curb to be covered. Then, the device is set up on the curb located at the starting point of the road. The operator holds the handle 2 and pushes the device forward. During the pushing process, the end of the plastic film first adheres to the curb. The top roller 4 is used to flatten and firmly adhere the top plastic film. The brush 9 is set at an angle to spread the plastic film downwards on the side, so that the plastic film on the side can be effectively attached to the side of the curb. Then, during the laying process, the plastic film roll 6 is gradually consumed. Under the elastic drive of the torsion spring 53, the plastic film roll 6 always elastically abuts against the top surface of the curb, so as to facilitate the smooth laying process.

[0026] This utility model's curbstone anti-pollution plastic film laying device achieves a dual improvement in construction efficiency and quality through mechanized design. It employs a guide wheel assembly and an adjustable film pressing mechanism to ensure neat and straight plastic film laying, effectively solving the problems of wrinkles or damage caused by traditional manual laying, reducing material waste by more than 50%. Only one person is needed to operate the automatic unwinding, pressing, and fixing, increasing construction efficiency by 3 times compared to manual labor and reducing labor costs by 60%. A brush 9 and top roller 4 are used to lay the plastic film on the curbstone after watering or adhesive application. The film adheres tightly to the curbstone surface, improving wind resistance and preventing detachment, protecting the curbstone throughout the entire process until the asphalt pavement layer is completed and removed. This device is also adaptable to curbstones of different heights and widths, balancing construction quality and economy.

[0027] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
