This application discloses an auxiliary clamp for controlling the elevation of asphalt paving based on the suspension line method.
[0038] The core of this utility model is to provide an auxiliary clamp for controlling the elevation of asphalt paving based on the suspension line method.
[0039] Please refer to Figures 1 to 3 The asphalt paving elevation control auxiliary clamp based on the suspension method provided by this utility model includes a clamp body 1, a fixing component 2, and a limiting seat 3. The clamp body 1 is a horizontal rod structure, and a level tube 11 is provided on the clamp body 1 to make the horizontal state of the clamp body 1 visible. The fixing component 2 is provided at one end of the clamp body 1 so that the clamp body 1 is fixedly suspended on one side of the paving area. The limiting seat 3 is provided on the clamp body 1, and a rope hole 31 perpendicular to the clamp body 1 is provided through the limiting seat 3 for threading a steel wire rope.
[0040] Specifically, refer to Figures 1 to 6 First, conduct a site survey of the tunnel or elevated area to determine the installation location of the clamp body 1. Use the fixing component 2 to fix the clamp body 1 to the tunnel enamel steel plate, railing, or crash barrier. Use the level tube 11 to ensure that the clamp body 1 is in a horizontal state. Pass the wire rope through the rope hole 31 and tension the wire rope to the preset tension value to complete the installation of the wire rope.
[0041] It should be noted that the limit seat 3 is thin-walled, and the four corners of the outer surface of the limit seat 3 are designed with smooth transitions to ensure that the paver's skid shoe is minimally disturbed when passing through the clamp.
[0042] The aforementioned auxiliary clamp for controlling asphalt paving elevation based on the suspension line method uses the fixing component 2 to fix the clamp body 1 to the tunnel enamel steel plate, railing or crash barrier, and passes the wire rope through the rope hole 31 to realize the hanging of the wire rope, thereby effectively solving the problem that the steel rod cannot be inserted and the wire rope cannot be fixed when the base layer has hardened.
[0043] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed introduction to the asphalt paving elevation control auxiliary fixture based on the suspension line method provided by this utility model.
[0044] Based on any of the above embodiments, refer to Figure 1 and Figure 2 The limiting seat 3 is slidably disposed on the fixture body 1, and a limiting component 4 is provided between the fixture body 1 and the limiting seat 3 so that the limiting seat 3 is fixedly limited on the fixture body 1.
[0045] Specifically, the clamp body 1 has a horizontally formed groove. The limiting seat 3 is a frame structure and is slidably fitted onto the clamp body 1. Two sliding plates are provided inside the limiting seat 3 to cooperate with the groove. The distance between the two sliding plates is the width of the groove. The two sliding plates abut against the upper and lower surfaces of the groove, respectively, and simultaneously cooperate with the upper and lower inner walls of the limiting seat 3, clamping the upper and lower parts of the clamp body 1, thus achieving stable sliding of the limiting seat 3 relative to the clamp body 1. The limiting component 4, located between the clamp body 1 and the limiting seat 3, fixes the limiting seat 3 relative to the clamp body 1, allowing the position of the limiting seat 3 to be adjusted according to specific working conditions and fixed by the limiting component 4. The limiting component 4 facilitates the adjustment of the limiting seat 3, ensuring that the paver's flatbed can be aligned with the edge during construction.
[0046] Based on any of the above embodiments, refer to Figure 1 and Figure 2 The limiting component 4 includes a threaded hole 41 on one side of the limiting seat 3. A limiting bolt 42 is connected to the threaded hole 41. The end of the limiting bolt 42 near the clamp body 1 abuts against the side wall of the clamp body 1.
[0047] Specifically, the position of the limiting bolt 42 can be adjusted by rotating it clockwise or counterclockwise. When the limiting seat 3 needs to slide, the limiting bolt 42 is unscrewed from the threaded hole 41, so that one end of the limiting bolt 42 is away from the side of the clamp body 1, which facilitates the sliding of the limiting seat 3. When the limiting seat 3 needs to be fixed, the limiting bolt 42 is screwed into the threaded hole 41, so that one end of the limiting bolt 42 abuts against the side of the clamp body 1, thereby preventing the limiting seat 3 from sliding further and thus fixing the limiting seat 3. This makes it easy to adjust and fix the limiting seat 3 as needed.
[0048] Based on any of the above embodiments, refer to Figure 1 The fixture body 1 is provided with a scale 12 along the sliding direction of the limiting seat 3 so as to make the position state of the limiting seat 3 visible.
[0049] Specifically, during the adjustment of the position of the limit seat 3, the position of the limit seat 3 can be observed through the scale 12 located on the fixture body 1, thereby realizing the visual expression of the position of the limit seat 3 and ensuring the accuracy during the movement of the limit seat 3.
[0050] Based on any of the above embodiments, refer to Figure 1 The fixing component 2 includes a U-shaped clamping plate 21 integrally formed with the clamping body 1 and a fixing structure 22 disposed on the U-shaped clamping plate 21. The fixing structure 22 is used to fix the plate to be clamped on the inner side of the U-shaped clamping plate 21 so that the clamping body 1 is fixedly suspended on one side of the paving area.
[0051] Specifically, based on the actual construction conditions on site, determine where to fix the clamp body 1, place the plate to be clamped (such as tunnel enamel steel plate, railing or anti-collision pier, etc.) between the two vertical plates of the U-shaped clamp 21, and fix it to the inside of the U-shaped clamp 21 through the fixing structure 22, thereby realizing the horizontal suspension of the clamp body 1, which facilitates the hanging of the wire rope.
[0052] Based on any of the above embodiments, refer to Figure 1 The fixing structure 22 includes a threaded hole 221 opened on the side of the U-shaped clamping plate 21 near the clamping body 1 and an adjusting rod 222 threadedly connected to the threaded hole 221. A clamping auxiliary plate 223 is provided at one end of the adjusting rod 222 located on the inner side of the U-shaped clamping plate 21.
[0053] Specifically, the plate to be clamped (such as a tunnel enamel steel plate, railing or crash barrier, etc.) is placed between the two vertical plates of the U-shaped clamping plate 21. The rotating adjusting rod 222 drives the clamping auxiliary plate 223 to move along the axis of the threaded hole 221 until the clamping auxiliary plate 223 cooperates with the U-shaped clamping plate 21 to fix the plate to be clamped between the two, thereby achieving the fixation of the clamping body 1.
[0054] It should be noted that, based on the structural shape of the plate to be clamped, the structural shape of the clamping web 223 and the U-shaped clamping plate 21 on the side near the plate to be clamped is adjusted to make the contact points of the three fit together, thereby facilitating the clamping and fixing of the plate to be clamped.
[0055] Furthermore, there are two sets of fixing structures 22, and the two sets of fixing structures 22 are respectively located at both ends of the U-shaped clamp 21 near the clamp body 1.
[0056] Specifically, by providing two sets of fixing structures 22, the stability of clamping and fixing the plate to be clamped can be further improved, thereby ensuring the stability of the fixture body 1. In other embodiments, multiple sets of fixing structures 22 can also be used for clamping and fixing to further improve the stability of the fixation.
[0057] Based on any of the above embodiments, refer to Figure 1 A first rubber pad 224 is provided on the side of the clamping auxiliary plate 223 away from the adjusting rod 222, and a second rubber pad 225 that cooperates with the first rubber pad 224 is provided on the inner side of the U-shaped clamping plate 21 away from the clamping body 1.
[0058] Specifically, during the clamping process of the U-shaped clamping plate 21 and the clamping auxiliary plate 223, the first rubber pad 224 and the second rubber pad 225 increase the friction between the U-shaped clamping plate 21, the clamping auxiliary plate 223 and the clamped object, thereby preventing the clamped object from sliding between them, thus further improving the stability of the fixation. At the same time, the first rubber pad 224 and the second rubber pad 225 can also effectively prevent damage to the surface of the clamped object.
[0059] Based on any of the above embodiments, refer to Figure 2 and Figure 3 A self-locking component 5 is provided at one end of the rope hole 31. The self-locking component 5 is used to keep the wire rope located in the rope hole 31 in a tensioned state.
[0060] Specifically, after the wire rope passes through the rope hole 31, it is initially tensioned. Then, it is locked into the wire rope's routing hole by the self-locking component 5. The internal stress of the wire rope, the routing hole, and the self-locking component 5 work together to ensure that the wire rope is always in a tensioned state and to prevent slack.
[0061] Furthermore, the self-locking component 5 includes a self-locking member 51 disposed at one end of the rope hole 31. The self-locking member 51 is composed of a rope threading part and a locking part, which are integrally formed. The rope threading part has a through hole 52 at the shaft part away from the locking part. The locking part is composed of multiple elastic elements in a conical shape, and a clamping opening 53 is formed at the end away from the rope threading part.
[0062] Specifically, after the wire rope passes through the rope hole 31, it is initially tensioned. Then, with the help of the through hole 52 and the clamping opening 53, the self-locking member 51 is locked into the wire rope's routing hole to ensure that the wire rope is in a tensioned state.
[0063] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0064] The above provides a detailed description of the asphalt paving elevation control auxiliary clamp based on the suspension line method provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
