Technical Field

[0001] The utility model relates to the technical field of road cement and asphalt concrete paving, in particular to a paving device with adjustable paving width. Background Technique

[0002] Road cement paving refers to the process of laying and covering the road surface with materials such as cement or concrete in road construction. This process involves evenly pouring concrete or cement slurry on the road surface, and then using equipment such as a paver to evenly level, vibrate and finish the surface to ensure the final paving quality and flatness. However, there are problems in the current medium-sized cement pavers during use, such as the inability to adjust the paving width or the cumbersome steps for adjusting the paving width.

[0003] For example, a paving width adjustment device for a paver with the authorization announcement number CN216786751U discloses a device that can adjust the paving width. However, the adjustment of the above paver width requires disassembling and adjusting the paving equipment, with cumbersome steps and inconvenient use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] It should be noted that, in the description of the present invention, the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0023] like Figure 1-3 As shown, the utility model provides a technical solution: a paving device with adjustable paving width, comprising:

[0024] The paving mechanism 1 is responsible for paving the material. The paving mechanism 1 mainly includes two paving boards 101. An appropriate gap is set between the two paving boards 101. An extension board 102 is installed at the gap to make the paving range wider. A control component is also installed between the two paving boards 101. The control component is responsible for controlling the two extension boards 102 to move toward one end away from the control component to adjust the paving width. In order to ensure the stability of paving, limit plates 6 are set at both ends of the paving mechanism 1. The function of the limit plates 6 is to limit the range of the paving area to ensure that the paving range can be changed according to actual conditions during the construction process;

[0025] A traction frame 2 is also provided on one side of the paving mechanism 1. The function of the traction frame 2 is to pull the device during the construction process to ensure that it can be stably advanced to perform paving work.

[0026] To ensure the smooth implementation of this embodiment, it should be understood that a connecting plate 103 is fixed between the paving plates 101. The control member includes hinge plates 105 slidably connected to both ends of the connecting plate 103. The two hinge plates 105 are connected by a brake plate 104 and are hinged to the brake plate 104. One end of each hinge plate 105 is hinged to the top of the extension plate 102. Convex strips are provided on both sides of the extension plate 102, and groove strips adapted to the convex strips are provided on one side of each paving plate 101. A U-shaped frame 106 is installed on the top of the connecting plate 103, and a numerical control oil cylinder 107 is installed on the top of the U-shaped frame 106. The telescopic end of the numerical control oil cylinder 107 is connected to the brake plate 104. This device controls the displacement of the extension plate 102 through the numerical control oil cylinder 107. When the numerical control oil cylinder 107 extends downward to press the brake plate 104 downward, the hinge plates 105 on both sides will push outward. The chute 108 on the hinge plate 105 provides conditions for the hinge plate 105 to extend outward. When the hinge plates 105 extend outward, since the extension plate 102 is limited by the groove strips, the extension plate 102 will extend parallel to both sides, and the bottom of the extension plate 102 is flush with the bottom of the paving plate 101. When the extension plate 102 extends outward to both sides, the paving width of the cement can be increased.

[0027] To ensure the smooth implementation of this embodiment, it should be understood that the limiting plate 6 is fixed to the extension plate 102. A paving area is formed between the two limiting plates 6. A number of paving rollers 7 are rotatably installed on one side of one of the limiting plates 6 facing the paving area. Through grooves adapted to the paving rollers 7 are provided on the other limiting plate 6. The length of the paving rollers 7 is greater than the length of the traction frame 2. The through grooves need to be adapted to the paving rollers 7 to prevent cement from overflowing from the gaps. When the paving range of this device becomes larger, to ensure the smooth progress of paving, the paving rollers 7 have sufficient length to meet the increase in the paving range.

[0028] To ensure the smooth implementation of this embodiment, it should be understood that a number of limiting rods 8 are fixed to one side of one of the limiting plates 6. Connecting plates 9 are provided at one end of each paving roller 7. The top of the connecting plate 9 slides on the surface of the limiting rod 8. When the paving width increases, the connecting plate 9 slides relative to the limiting plate 6, which can not only meet the increase in the paving width, but also provide sufficient support for the paving rollers 7, and the effect is better.

[0029] To ensure the smooth implementation of this embodiment, it should be understood that a number of rollers 3 are provided at both ends of the traction frame 2. The paving mechanism 1 is connected to the traction frame 2 through a traction rope 5. A number of hanging rings 4 are also installed on the traction frame 2. The traction frame 2 cooperates with a supporting traction device to realize the traction of this paving device.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
