However, these methods have many shortcomings. During the measurement process, the total station needs to be moved frequently, which is not only time-consuming and labor-intensive, but also affects the efficiency and convenience of the measurement.

[0028] This utility model provides the following technical solution:

[0029] Example 1

[0030] Please see Figure 1-5 This utility model provides a technical solution: an asphalt pavement paving elevation setting-out device, including a mobile platform 1, a universal wheel 2 fixedly connected to the bottom of the mobile platform 1, a handrail 3 fixedly connected to the left side of the mobile platform 1, a first measuring mechanism 4 set on the top of the mobile platform 1, and a second measuring mechanism 5 set on the right side of the mobile platform 1.

[0031] The first measuring mechanism 4 includes a support platform 41, which is slidably connected to the top of the movable platform 1. Connecting frames 43 are fixedly connected to the left and right sides of the top of the support platform 41. The connecting frames 43 are located on the top of the movable platform 1, and a limit pin 44 is threadedly connected inside the connecting frame 43. A fixed frame 42 is fixedly connected to the top of the support platform 41. A fixed plate 45 is fixedly connected to the inner side of the fixed frame 42. An adjusting shaft 46 is rotatably connected inside the fixed plate 45. A movable frame 47 is threadedly connected to the outer side of the adjusting shaft 46. A fixed component is fixedly connected to the top of the movable frame 47. The top plate 48 has a mounting base 49 rotatably connected inside it. The bottom of the mounting base 49 is fixedly connected to a limit plate 494. The total station 491 is slidably connected inside the mounting base 49. The total station 491 is threadedly connected to a fixed shaft 492. The bottom rear side of the top plate 48 is fixedly connected to a connecting plate 493. The connecting plate 493 is slidably connected to a plug rod 495. The front side of the plug rod 495 is inserted into the limit plate 494. The rear side of the plug rod 495 is fixedly connected to a pull ring 496. The plug rod 495 is sleeved with a spring 497.

[0032] The bottom of the connecting frame 43 is in contact with the top of the moving platform 1. The bottom of the limiting pin 44 is threaded into the inside of the moving platform 1, which facilitates the stability between the connecting frame 43 and the moving platform 1 under the action of the limiting pin 44. The top of the adjusting shaft 46 is rotatably connected to the top of the fixed frame 42. The moving frame 47 is slidably connected to the inside of the fixed frame 42. The top of the pull ring 496 is slidably connected to the bottom of the top plate 48, which facilitates the movement of the top plate 48 by the moving frame 47 to adjust the height of the total station 491.

[0033] The front side of spring 497 is fixedly connected to the rear side of connecting plate 493, and the rear side of spring 497 is fixedly connected to the front side of pull ring 496, so as to ensure the stability of plug rod 495 under the action of spring 497. Fixed shaft 492 passes through the inside of mounting base 49. Fixed grooves are respectively opened inside total station 491 and mounting base 49, and the two fixed grooves correspond to each other. Fixed shaft 492 is threaded into fixed groove, so as to fix total station 491 under the action of fixed shaft 492, and at the same time, it is easy to install and disassemble.

[0034] Example 2

[0035] Please see Figure 1-5 Furthermore, based on Embodiment 1, the second measuring mechanism 5 includes a placement frame 51, which is fixedly connected to the right side of the moving platform 1. A support plate 52 is fixedly connected to the bottom right side of the placement frame 51. A counterweight base 53 is slidably connected inside the placement frame 51. A scale rod 54 is fixedly connected to the top of the counterweight base 53. A scale line 55 is fixedly connected to the periphery of the scale rod 54. A bracket 56 is slidably connected to the periphery of the scale rod 54. The bracket 56 is located inside the support plate 52.

[0036] The bottom of the bracket 56 is in contact with the inner side of the support plate 52. There are three sets of counterweight base 53, marker 54, scale line 55 and bracket 56. The three sets of counterweight base 53, marker 54, scale line 55 and bracket 56 are symmetrically distributed inside the placement frame 51, which makes it convenient to perform elevation measurement at multiple points by setting three sets.

[0037] In actual operation, when this device is used, and elevation setting is required during asphalt pavement paving, the load-bearing platform 41 is first slidably connected to the top of the mobile platform 1, so that the bottom of the connecting frame 43 is in contact with the top of the mobile platform 1. The connecting frame 43 is fixed by the limiting pin 44, which can ensure the stability of the load-bearing platform 41. At the same time, the total station 491 is slidably connected to the inside of the mounting base 49, and the total station 491 is fixed by the fixed shaft 492, which passes through the inside of the mounting base 49, improving the convenience of installation and disassembly. The bottom of the mobile platform 1 is equipped with casters 2 and handrails 3, so that the total station 491 can be flexibly moved to different construction points without manual handling, greatly reducing the labor intensity of construction personnel. When moved to the designated position, it can be self-locked by the self-locking structure carried by the casters 2, ensuring the stability during use.

[0038] The placement frame 51 is equipped with three sets of counterweight bases 53, a marker 54, a scale line 55, and a bracket 56, which can simultaneously measure elevation at multiple points. By comparing multiple sets of data, the reliability and accuracy of the measurement results are effectively improved. During measurement, the counterweight bases 53 and the marker 54 are placed in the designated positions, and the bracket 56 is slidably connected to the outside of the marker 54. The cooperation between the bracket 56 and the counterweight bases 53 provides stable support for the marker 54, ensuring that the marker 54 remains vertical during the measurement process and avoiding measurement deviations due to tilting.

[0039] Simultaneously, the moving frame 47 drives the top plate 48 through the rotation adjustment shaft 46, enabling precise adjustment of the total station 491's height to meet different paving elevation measurement needs. When angle adjustment is required, pull the pull ring 496 backward, causing the pull ring 496 to move the insertion rod 495 and deform the spring 497, thus releasing the limit plate 494. Rotating the mounting base 49 allows for adjustment of the total station 491's angle. After adjustment, the pull ring 496 can be released, the spring 497 returns to its original position, and the insertion rod 495 is re-inserted into the limit plate 494, which can also securely lock it during measurement, preventing measurement errors caused by shaking.

[0040] By combining a total station 491 with a marker 54, a suitable location is selected near the paved section to set up a measurement benchmark. The total station 491 is used to measure and determine the elevation of the benchmark. The benchmark should be selected in a stable location that is not easily affected by construction, and it should be marked and protected. According to the paving width and construction requirements, a marker 54 is placed at regular intervals on both sides of the paved section. The total station 491 is used to observe the marker 54, so that the scale line 55 on the marker 54 corresponds to the design elevation. The reading of the horizontal line of sight of the total station 491 on the marker 54 is equal to the difference between the design elevation and the benchmark elevation, and the measurement work can be completed.

[0041] Using a total station 491 and a benchmark 54 for elevation setting out is common knowledge for those skilled in the art, and this case will not describe the specific operating steps in detail.

[0042] The total station model 491 is a Leica TS06 series.
