Description

Technical Field

[0001] This utility model relates to the field of asphalt pavement construction technology, and specifically to an asphalt pavement construction template positioning structure. Background Technology

[0002] During the asphalt pavement construction phase, to prevent excessive outward expansion of the asphalt mixture during paving and compaction, retaining formwork needs to be installed on both sides of the subgrade (water-stabilized base course) before paving and compaction. Furthermore, in recent years, with the widespread application of intelligent pavers, their efficient and precise operating modes have placed higher demands on the stability of the retaining formwork. Intelligent pavers, through automatic driving technology, 3D leveling technology, and high-precision positioning technology, can achieve high-precision paving and compaction operations.

[0003] Currently, under the vibration and strong extrusion force of unmanned pavers, to prevent misalignment between adjacent sets of retaining templates, a positioning structure is usually installed to connect the two sets of retaining templates. For example, Chinese patent application number 202320843461.X discloses a fixing device for water-stabilized templates. Most existing template positioning structures are simple in design, mainly consisting of a fixing ring, a fixing post, and a pin. During positioning and connection, the fixing post must be inserted into the fixing ring, and the ends of the two sets of retaining templates must be brought together to align the pin holes on the fixing ring and the fixing post. Then, the pin is inserted into the pin hole for fixing. This positioning connection method requires the ends of the two sets of retaining templates to be brought together and kept in a close fit before the fixing operation can be performed, which is cumbersome and laborious, reducing the practicality of the device. Therefore, to address the above technical problems, a template positioning structure for asphalt pavement construction is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a positioning structure for asphalt pavement construction templates, which facilitates and saves effort in positioning and connecting the template body, thereby improving the practicality of the device.

[0005] A formwork positioning structure for asphalt pavement construction, comprising:

[0006] Multiple sets of template bodies, each set of template bodies having mounting columns at both ends;

[0007] A positioning assembly includes positioning sleeves and positioning shafts. Two sets of positioning sleeves are arranged opposite each other on one set of mounting posts, and two sets of positioning shafts parallel to the template body are arranged opposite each other on another set of mounting posts. Two sets of positioning shafts in two adjacent sets of template bodies can pass through the two sets of positioning sleeves.

[0008] A fixing component includes an internal threaded sleeve, which is coaxially and rotatably disposed on one set of positioning sleeves, wherein the positioning shaft is provided with an external thread, and the internal threaded sleeve can be connected to the external thread.

[0009] The beneficial effects of the above-mentioned asphalt pavement construction formwork positioning structure are as follows:

[0010] By inserting two sets of positioning shafts from two adjacent sets of template bodies into two sets of positioning sleeves, and rotating the inner threaded sleeve to engage the outer thread, the rotation of the inner threaded sleeve and the engagement of the outer thread drive the positioning shaft to move the two sets of template bodies closer together. When the ends of the two sets of template bodies are in contact, the inner threaded sleeve stops rotating. At this point, the engagement of the inner threaded sleeve and the outer thread fixes the positioning shaft, thereby positioning and connecting the two sets of template bodies. The positioning connection is completed at the same time the ends of the two sets of template bodies are in contact, which is convenient and labor-saving, and improves the practicality of the device.

[0011] In one embodiment, the template body is L-shaped, and the mounting column is connected at both ends to the vertical and horizontal ends of the template body, respectively. The mounting column can improve the compressive strength of the vertical end of the template body.

[0012] In one embodiment, both sets of positioning shafts are coaxially provided with guide cones at one end. The guide cones can guide the positioning shafts when they pass through the positioning sleeve, improving the ease of insertion of the positioning shafts into the positioning sleeve.

[0013] In one embodiment, the internal threaded sleeve is provided with anti-slip grooves on its circumference, and multiple sets of anti-slip grooves are spaced apart along the circumference of the internal threaded sleeve. By providing multiple sets of anti-slip grooves, the stability of holding the internal threaded sleeve can be improved, and slippage can be avoided when rotating the internal threaded sleeve.

[0014] In one embodiment, the positioning assembly further includes a rotating assembly. Both sets of positioning shafts are connected to the mounting column via the rotating assembly. Adjusting the rotating assembly allows the positioning shafts to extend beyond the end of the template body or be positioned inside the template body. By adjusting the rotating assembly to position the positioning shafts inside the template body, the space occupied by the template body is reduced during transportation and storage. Furthermore, it effectively reduces the risk of deformation caused by collisions with external instruments during handling, thereby extending the service life of the positioning shafts.

[0015] In one embodiment, the rotating assembly includes a connecting sleeve and a fixing knob. Each of the two sets of positioning shafts has a connecting sleeve at one end. The connecting sleeve is coaxially and rotatably fitted onto the mounting post. The fixing knob is threaded onto the connecting sleeve. The mounting post has a first positioning hole and a second positioning hole opposite to each other. The fixing knob can be selectively inserted into either the first or second positioning hole. By rotating the fixing knob out of the first positioning hole, then rotating the connecting sleeve to align the fixing knob with the second positioning hole, and then rotating the fixing knob to insert it into the second positioning hole, the positioning shaft can be placed inside the template body. Conversely, by rotating the fixing knob out of the second positioning hole, then rotating the connecting sleeve in the opposite direction to align the fixing knob with the first positioning hole, and then rotating the fixing knob to insert it into the first positioning hole, the positioning shaft can extend out of the template body end. Adjusting the positioning shaft to extend out of the template body end or be placed inside the template body is convenient.

[0016] In one embodiment, the mounting post is provided with retaining rings that abut against both ends of the connecting sleeve. The retaining rings prevent the connecting sleeve from sliding along the axial direction of the mounting post during rotation, facilitating the alignment of the fixing knob with the first or second positioning hole.

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] Please see Figure 1 and Figure 2 One embodiment of an asphalt pavement construction template positioning structure includes multiple sets of template bodies 10, positioning components, and fixing components.

[0029] Specifically, each of the multiple sets of template bodies 10 has a mounting post 101 at both ends. The positioning assembly includes a positioning sleeve 20 and a positioning shaft 201. Two sets of positioning sleeves 20 are arranged opposite each other on one set of mounting posts 101, and two sets of positioning shafts 201 parallel to the template body 10 are arranged opposite each other on the other set of mounting posts 101. The two sets of positioning shafts 201 in two adjacent sets of template bodies 10 can pass through the two sets of positioning sleeves 20. The fixing assembly includes an internal threaded sleeve 30, which is coaxially and rotatably mounted on one set of positioning sleeves 20. One set of positioning shafts 201 is provided with an external thread 301, and the internal threaded sleeve 30 can connect with the external thread 301.

[0030] Specifically, in the above embodiments, a set of positioning sleeves 20 has a fixed ring groove on its circumferential side, and a connecting ring is provided on the internal threaded sleeve 30. The connecting ring is rotatably disposed in the fixed ring groove.

[0031] In the above embodiment, by inserting two sets of positioning shafts 201 in two adjacent sets of template bodies 10 into two sets of positioning sleeves 20, and rotating the inner threaded sleeve 30 to engage with the outer thread 301, the rotation of the inner threaded sleeve 30 and the engagement with the outer thread 301 drive the positioning shaft 201 to move the two sets of template bodies 10 closer together. When the ends of the two sets of template bodies 10 are in contact, the inner threaded sleeve 30 stops rotating. At this time, the engagement of the inner threaded sleeve 30 and the outer thread 301 can fix the positioning shaft 201, thereby positioning and connecting the two sets of template bodies 10. The positioning connection can be completed at the same time that the ends of the two sets of template bodies 10 are in contact, which is convenient and labor-saving, and improves the practicality of the device.

[0032] Please see Figure 1 and Figure 2 In one embodiment, the template body 10 is L-shaped, and the two ends of the mounting column 101 are connected to the vertical end and the horizontal end of the template body 10, respectively. The mounting column 101 supports the vertical end of the template body 10, which can improve the compressive strength of the vertical end of the template body 10, thereby improving the stability of the overall structure of the device.

[0033] Please see Figure 1 and Figure 2 In one embodiment, each of the two sets of positioning shafts 201 has a guide cone 2011 coaxially arranged at one end. The guide cone 2011 can guide the positioning shaft 201 when it passes through the positioning sleeve 20, thereby improving the ease of passing the positioning shaft 201 through the positioning sleeve 20.

[0034] Please see Figure 2 In one embodiment, an anti-slip groove 302 is provided on the circumferential side of the internal threaded sleeve 30, and multiple sets of anti-slip grooves 302 are spaced apart along the circumference of the internal threaded sleeve 30. By providing multiple sets of anti-slip grooves 302, the stability of holding the internal threaded sleeve 30 can be improved, and slippage can be avoided when rotating the internal threaded sleeve 30.

[0035] Please see Figures 2 to 5 In one embodiment, the positioning component further includes a rotating component. Both sets of positioning shafts 201 are connected to the mounting column 101 through the rotating component. Adjusting the rotating component can cause the positioning shafts 201 to extend out of the end of the template body 10 or be placed inside the template body 10.

[0036] In the above embodiments, by adjusting the rotating assembly to position the positioning shaft 201 inside the template body 10, the space occupied by the template body 10 during transportation and storage is reduced. Furthermore, during handling, the risk of deformation due to collisions between the positioning shaft 201 and external instruments is effectively reduced, thus improving the service life of the positioning shaft 201. It is understood that when the positioning shaft 201 extends beyond the end of the template body 10 by adjusting the rotating assembly, it can be inserted into the positioning sleeve 20 of an adjacent template body 10 for positioning connection.

[0037] Specifically, in the above embodiments, the rotating assembly includes a connecting sleeve 202 and a fixing knob 203; one end of each of the two sets of positioning shafts 201 is provided with a connecting sleeve 202, the connecting sleeve 202 is coaxially and rotatably sleeved on the mounting post 101, the fixing knob 203 is threadedly connected to the connecting sleeve 202, the mounting post 101 is provided with a first positioning hole 1011 and a second positioning hole 1012 opposite to each other, and the fixing knob 203 can be selectively inserted into the first positioning hole 1011 or the second positioning hole 1012.

[0038] By rotating the fixing knob 203 to exit from the first positioning hole 1011, and then rotating the connecting sleeve 202 to align the fixing knob 203 with the second positioning hole 1012, the positioning shaft 201 can be placed inside the template body 10 by rotating the fixing knob 203 to exit from the second positioning hole 1012, and then rotating the connecting sleeve 202 in the opposite direction to align the fixing knob 203 with the first positioning hole 1011, the positioning shaft 201 can be extended out of the end of the template body 10 by rotating the fixing knob 203 to exit from the second positioning hole 1012, and then rotating the fixing knob 203 to align with the first positioning hole 1011 by rotating the fixing knob 203 to extend into the first positioning hole 1011. It is convenient to adjust the positioning shaft 201 to extend out of the end of the template body 10 or to be placed inside the template body 10.

[0039] Based on the above embodiments, the mounting post 101 is further provided with retaining rings 1013 that abut against both ends of the connecting sleeve 202. By providing retaining rings 1013, the connecting sleeve 202 can be prevented from sliding along the axial direction of the mounting post 101 when rotating, which facilitates the fixing knob 203 to correspond with the first positioning hole 1011 or the second positioning hole 1012.

[0040] The specific implementation method of the above-mentioned asphalt pavement construction formwork positioning structure is as follows:

[0041] By inserting two sets of positioning shafts 201 in two adjacent sets of template bodies 10 into two sets of positioning sleeves 20, and rotating the inner threaded sleeve 30 to engage with the outer thread 301, the rotation of the inner threaded sleeve 30 and the engagement with the outer thread 301 drive the positioning shaft 201 to move the two sets of template bodies 10 closer together. When the ends of the two sets of template bodies 10 are in contact, the inner threaded sleeve 30 stops rotating. At this time, the engagement of the inner threaded sleeve 30 and the outer thread 301 can fix the positioning shaft 201, thereby positioning and connecting the two sets of template bodies 10. The positioning connection can be completed at the same time that the ends of the two sets of template bodies 10 are in contact, which is convenient and labor-saving and improves the practicality of the device.

[0042] During disassembly, the positioning shaft 201 can be driven to move the two sets of template bodies 10 away by rotating the inner threaded sleeve 30 in the opposite direction to engage with the outer thread 301. When the inner threaded sleeve 30 and the outer thread 301 are separated, the positioning shaft 201 can be pulled out from the positioning sleeve 20, making disassembly convenient. After disassembly, the fixing knob 203 can be rotated to exit from the first positioning hole 1011, and then the connecting sleeve 202 can be rotated to make the fixing knob 203 correspond to the second positioning hole 1012. Then, the fixing knob 203 can be rotated to pass through the second positioning hole 1012, and the positioning shaft 201 can be placed inside the template body 10. At this time, the space occupied by the template body 10 can be reduced, which facilitates the transportation and storage of the template body 10. At the same time, during the handling process, the risk of deformation caused by collision between the positioning shaft 201 and external instruments can be effectively reduced, and the service life of the positioning shaft 201 can be improved.
