Abstract
Description
Technical Field
[0001] This utility model relates to the field of road construction equipment technology, and in particular to a stringing device for asphalt pavement paving construction. Background Technology
[0002] During the asphalt pavement paving process, the string line device is used to determine the paving reference surface, which plays a key role in ensuring the quality indicators such as the smoothness and slope of the paved pavement.
[0003] Traditional stringing devices have many drawbacks. Some stringing devices are not very stable. During construction, the positioning line is prone to displacement or shaking due to external factors such as mechanical vibration and wind, causing the stringing line to deviate from the reference position, which in turn affects the paving quality of the asphalt pavement. In addition, the adjustment function of traditional stringing devices is limited, making it difficult to adapt to the construction requirements of different road slopes and paving widths, and lacking flexibility.
[0004] Therefore, developing a convenient, stable, and flexible asphalt pavement paving construction line hanging device is of great practical significance.
[0005] To address the above issues, we have developed a line-hanging device for asphalt pavement paving construction. Utility Model Content
[0006] This utility model discloses an asphalt pavement paving construction line hanging device, which aims to solve the technical problems in the background art.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A line-hanging device for asphalt pavement paving construction includes a base, a vertical pole fixedly connected to the top of the base, a height adjustment plate slidably connected to the outside of the vertical pole, a transmission groove inside the height adjustment plate, a rack fixedly connected to one side of the vertical pole and inside the transmission groove, a first motor fixedly connected to one side of the height adjustment plate, the output shaft of the first motor extending into the transmission groove and fixedly connected to a gear, the gear meshing with the rack, a winding groove on one side of the height adjustment plate, a winding spool rotatably connected inside the winding groove, a positioning line wound around the outside of the winding spool, a line-hanging hook fixedly connected to the end of the positioning line away from the winding spool, and a tensioning frame connected to one side of the height adjustment plate by fastening screws, the tensioning frame cooperating with the positioning line.
[0009] By setting the uprights vertically on the base, when the height of the height adjustment plate needs to be adjusted, the first motor is started to drive the gear to rotate. Since the gear meshes with the rack, the rotation of the gear will cause the height adjustment plate to slide up and down along the uprights, pulling the positioning line out from the winding shaft in the winding groove. The positioning line is then hung in the required position by the hanging hook, and then the positioning line is tightened by the tensioning frame to serve as a reference line for asphalt pavement paving. By adjusting the height of the height adjustment plate, the positioning line is placed at a suitable height position, providing an accurate paving height reference for the asphalt paver.
[0010] In a preferred embodiment, both sides of the upright are fixedly connected to limit slide rails, and the height adjustment plate is slidably connected to the limit slide rails.
[0011] By setting the height adjustment plate to slide upwards, the limiting slide rail ensures that the height adjustment plate can only slide along the vertical direction of the upright, without any deviation or wobbling, thus making the height position of the positioning line more accurate.
[0012] In a preferred embodiment, a second motor is fixedly connected to one side of the height adjustment plate and to the side of the first motor, and the output shaft of the second motor extends into the inside of the winding groove and is fixedly connected to one end of the winding shaft.
[0013] By setting the second motor to rotate the winding shaft when the positioning line needs to be wound up or down, and the second motor to rotate the winding shaft to release the positioning line when the positioning line needs to be released, the positioning line can be retrieved quickly and conveniently, improving construction efficiency and avoiding messy tangling of the positioning line.
[0014] In a preferred embodiment, a height scale is embedded on the side of the upright away from the rack, and a marking arrow is fixedly connected to the top of the height adjustment plate, the marking arrow being used in conjunction with the height scale.
[0015] By observing the scale value on the height gauge indicated by the arrow when adjusting the height of the height adjustment plate, the height position of the plate can be accurately determined. This allows for quick and accurate adjustment of the positioning line to the required height, improving the precision and efficiency of construction.
[0016] In a preferred embodiment, the base has a base plate at its bottom, and four side ears are symmetrically fixedly connected to the bottom of the outer side of the base. Each side ear is connected to the base plate by a fastening screw.
[0017] By placing the base on the ground and then placing the bottom plate under the base when installing the hanging device, and fixing the side ears to the bottom plate with fastening screws, the contact area between the hanging device and the ground can be increased. This connection method allows it to be placed stably on the ground, ensuring the stability and accuracy of the positioning line.
[0018] In a preferred embodiment, four levels are symmetrically fixedly connected to the top of the base plate.
[0019] By observing the level on the top of the base plate during the installation of the hanging line device, when the level shows horizontal, it indicates that the hanging line device is in a horizontal state. Through the monitoring of the level, the hanging line device can be quickly and accurately adjusted to a horizontal state, ensuring the horizontality of the positioning line and providing an accurate reference for asphalt pavement paving.
[0020] In a preferred embodiment, two mounting slots are provided on both sides of the base plate, and the base plate is connected to the horizontal reference plane through the mounting slots.
[0021] By using mounting grooves to connect the base plate to the horizontal reference surface, the hanging device always maintains a stable and accurate horizontal position, providing a reliable reference line for asphalt paving and ensuring the flatness and quality of the track.
[0022] The asphalt pavement paving construction line hanging device provided by this utility model has the following advantages:
[0023] In this utility model, the first motor is started to drive the gear to rotate. Since the gear meshes with the rack, the rotation of the gear will cause the height adjustment plate to slide up and down along the upright, pulling the positioning line out from the winding shaft in the winding groove, hanging it in the required position by the hanging hook, and then using the tensioning frame to tighten the positioning line.
[0024] 1. The adjustable height of the hanging line allows the hanging device to adapt to different road slopes and paving widths, improving the applicability and flexibility of the device.
[0025] 2. The taut line frame provides a stable height reference for the positioning line, ensuring that the paving thickness and elevation meet the design requirements. It also ensures that the paver spreads the asphalt mixture evenly along the baseline, avoiding uneven road surfaces caused by loose positioning lines. This greatly improves the work quality and efficiency compared to traditional devices. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0033] The asphalt pavement paving construction line hanging device disclosed in this utility model is mainly used in road construction equipment scenarios.
[0034] Reference Figures 1-5A line-hanging device for asphalt pavement paving construction includes a base 1, a pole 2 fixedly connected to the top of the base 1, a height adjustment plate 3 slidably connected to the outside of the pole 2, a transmission groove 5 inside the height adjustment plate 3, a rack 4 fixedly connected to one side of the pole 2 and inside the transmission groove 5, a first motor 6 fixedly connected to one side of the height adjustment plate 3, the output shaft of the first motor 6 extending into the transmission groove 5 and fixedly connected to a gear 7, the gear 7 meshing with the rack 4, a winding groove 8 on one side of the height adjustment plate 3, a winding shaft 9 rotatably connected inside the winding groove 8, a positioning line 10 wound around the outside of the winding shaft 9, a line hook 11 fixedly connected to the end of the positioning line 10 away from the winding shaft 9, and a tensioning frame 14 connected to one side of the height adjustment plate 3 by fastening screws, the tensioning frame 14 working in conjunction with the positioning line 10.
[0035] In this embodiment: The upright 2 stands vertically on the base 1. When the height of the height adjustment plate 3 needs to be adjusted, the first motor 6 is started to drive the gear 7 to rotate. Since the gear 7 meshes with the rack 4, the rotation of the gear 7 will cause the height adjustment plate 3 to slide up and down along the upright 2, pulling the positioning line 10 out from the winding shaft 9 in the winding groove 8 and hanging it in the required position through the hanging hook 11. Then, the positioning line 10 is tightened by the tensioning frame 14 to serve as a reference line for asphalt pavement paving. By adjusting the height of the height adjustment plate 3, the positioning line 10 is placed at a suitable height position, providing an accurate paving height reference for the asphalt paver.
[0036] In a preferred embodiment, both sides of the upright 2 are fixedly connected to limit slide rails 12, and the height adjustment plate 3 is slidably connected to the limit slide rails 12.
[0037] In this embodiment, during the upward sliding process of the height adjustment plate 3, due to the limitation of the limit slide rail 12, the height adjustment plate 3 can only slide along the vertical direction of the upright 2, and there will be no deviation or shaking, thereby making the height position of the positioning line 10 more accurate.
[0038] In a preferred embodiment, a second motor 13 is fixedly connected to one side of the height adjustment plate 3 and to the side of the first motor 6. The output shaft of the second motor 13 extends into the interior of the winding groove 8 and is fixedly connected to one end of the winding shaft 9.
[0039] In this embodiment, when it is necessary to retract or extend the positioning line 10, the second motor 13 is started to drive the winding shaft 9 to rotate, and the positioning line 10 is wound around the winding shaft 9. Alternatively, when it is necessary to extend the positioning line 10, the second motor 13 is started in reverse to rotate the winding shaft 9 and extend the positioning line 10. This allows for quick and convenient retraction of the positioning line 10, improving construction efficiency and avoiding messy tangling of the positioning line 10.
[0040] In a preferred embodiment, a height scale 15 is inlaid on the side of the upright 2 away from the rack 4, and an indicator arrow 16 is fixedly connected to the top of the height adjustment plate 3. The indicator arrow 16 is used in conjunction with the height scale 15.
[0041] In this embodiment, when adjusting the height of the height adjustment plate 3, the height position of the height adjustment plate 3 can be accurately determined by observing the scale value on the height scale 15 pointed to by the indicator arrow 16. This allows the positioning line 10 to be adjusted to the required height quickly and accurately, improving the accuracy and efficiency of construction.
[0042] In a preferred embodiment, a base plate 18 is provided at the bottom of the base 1, and four side ears 17 are symmetrically fixedly connected to the bottom of the outer side of the base 1. The side ears 17 are all connected to the base plate 18 by fastening screws.
[0043] In this embodiment, when installing the hanging device, the base 1 is placed on the ground, and then the base plate 18 is placed under the base 1. The side ears 17 are fixedly connected to the base plate 18 by fastening screws, which can increase the contact area between the hanging device and the ground. Through this connection method, it can be placed stably on the ground, ensuring the stability and accuracy of the positioning line 10.
[0044] In a preferred embodiment, four levels 19 are symmetrically fixed to the top of the base plate 18.
[0045] In this embodiment: When installing the hanging device, observe the level 19 on the top of the base plate 18. When the level 19 shows horizontal, it indicates that the hanging device is in a horizontal state. Through the monitoring of the level 19, the hanging device can be quickly and accurately adjusted to a horizontal state, ensuring the levelness of the positioning line 10 and providing an accurate reference for asphalt pavement paving.
[0046] In a preferred embodiment, two mounting slots 20 are provided on both sides of the base plate 18, and the base plate 18 is connected to the horizontal reference plane through the mounting slots 20.
[0047] In this embodiment, the base plate 18 is connected to the horizontal reference plane using the mounting groove 20. The hanging device always maintains a stable and accurate horizontal position, providing a reliable reference line for asphalt paving and ensuring the flatness and quality of the track.
[0048] Working principle: When in use, firstly, the base plate 18 is fixed on the horizontal reference surface by the mounting groove 20 to ensure the stability of the device. The level 19 is used to monitor the horizontal status of the base plate 18 in real time.
[0049] The first motor 6 starts, driving the gear 7 to rotate. The gear 7 meshes with the rack 4, driving the height adjustment plate 3 to slide up and down along the limit slide rail 12 to achieve height adjustment. The height scale 15 and the marking arrow 16 work together to precisely control the position of the height adjustment plate 3.
[0050] The second motor 13 starts and drives the winding shaft 9 to rotate. The positioning line 10 on the winding shaft 9 is kept taut by the tensioning frame 14, and the hook 11 is used to fix the positioning line 10.
[0051] When it is necessary to adjust the length of the positioning line 10, start the second motor 13, rotate the winding shaft 9, release or retract the positioning line 10, and ensure that the length and tension of the positioning line 10 meet the construction requirements.
[0052] Both the first motor 6 and the second motor 13 are electrically connected to external control equipment and work together to achieve precise adjustment of height and positioning line 10 length. The stability of the device is ensured by the base plate 18 and the level 19, and the smoothness of the adjustment process and the tightness of the positioning line 10 are ensured by the limit slide rail 12 and the tensioning frame 14. It is suitable for precise line hanging operations in asphalt pavement paving construction, improving construction efficiency and accuracy.
[0053] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
