The guide beam positioning support mechanism includes a mounting seat 3, an adjusting rod 4, a guide beam seat 5, a mounting seat 6, and a laser emitter 7. The adjusting rod 4 is vertically sleeved on the mounting seat 3, and the adjusting rod 4 can be adjusted up and down and positioned relative to the mounting seat 3. The adjusting rod 4 can be adjusted up and down, which is conducive to achieving the height adjustment of the laser emitter 7, and then it is convenient to achieve the horizontal coincidence of the laser beam and the marking point 11. The guide beam seat 5 is sleeved on the adjusting rod 4, and the guide beam seat 5 can be rotated, adjusted up and down and positioned relative to the adjusting rod 4, that is, the guide beam The seat 5 can be rotated and adjusted relative to the adjusting rod 4, and can be adjusted up and down, which is conducive to adjusting the up and down distance between the guide beam seat 5 and the laser beam, and at the same time, the guide beam seat 5 can smoothly support the end of the guide beam 2. The mounting seat 6 is arranged on the top of the adjusting rod 4, and the mounting seat 6 can be freely rotated and positioned relative to the adjusting rod 4. The laser emitter 7 is fixedly arranged on the upper part of the mounting seat 6, and the mounting seat 6 can be rotated and adjusted, so as to facilitate the adjustment of the direction of the laser beam emitted by the laser emitter 7, so that the laser beam 72 can be smoothly irradiated to the marking point 11, and the end of the guide beam 2 can be clamped on the corresponding guide beam seat 5, and the upper plane of the guide beam 2 is flush with the upper plane of the guide beam seat 5. The principle of using the utility model to perform elevation positioning of the guide beam 2 is as follows: first, set the vertical distance H1 between the laser beam 72 and the upper plane of the guide beam seat 5. After H1 is set, fix the receiving plate 1 on one side of the steel wire conductor on one side of the road surface. At the same time, adjust the height of the receiving plate 1 so that the vertical distance H2 from the marking point 11 to the upper part of the steel wire conductor is equal to H1. Because the upper plane of the guide beam 2 is flush with the upper plane of the guide beam seat 5, after ensuring that H2 is equal to H1, the upper plane of the guide beam 2 is determined, and the two ends of the guide beam 2 are respectively clamped on the two guide beam seats 5 correspondingly distributed in the front and rear to achieve the elevation positioning of the guide beam 2.

[0020] On the basis of the above embodiment, in order to facilitate the fixation of the receiving plate 1 at the steel wire conductor 9, a positioning rod 12 is fixedly provided at the lower part of the receiving plate 1, and the bottom of the positioning rod 12 is conical, which makes it easy to knock the upper part of the receiving plate 1 so that it can be smoothly inserted into the ground.

[0021] On the basis of the above embodiment, the specific implementation of the mounting base 3 is as follows: the mounting base 3 includes a fixed tube 31, the lower part of the adjusting rod 4 is sleeved in the fixed tube 31, and three supporting legs 32 are arranged on the outer wall of the fixed tube 31 and are evenly spaced along its circumferential direction. The upper part of the supporting leg 32 is hingedly connected to the outer wall of the fixed tube 31 and the supporting leg 32 is telescopic and adjustable, and the supporting leg 31 is telescopic and adjustable, so that it is convenient to adjust the verticality of the fixed tube 31 in actual application, so as to ensure that the laser beam 72 emitted by the laser emitter 7 is in a horizontal state. Furthermore, the specific implementation of the adjusting rod 4 being sleeved in the fixed tube 31 is as follows: the lower part of the adjusting rod 4 is a smooth rod that fits with the inner wall of the fixed tube 31, and the outer wall of the smooth rod fits with the inner wall of the fixed tube 31, which effectively ensures that the adjusting rod 4 and the fixed tube 31 are coaxially distributed, and then facilitates the verticality adjustment of the adjusting rod 4 by adjusting the supporting legs 32. An external thread is provided on the upper side of the smooth rod, and an adjusting nut 41 is sleeved on the external thread and the lower plane of the adjusting nut 41 fits with the upper plane of the fixed tube. By rotating the adjusting nut 41, the height adjustment of the adjusting rod 4 is achieved, and then the height adjustment of the laser emitter 7 is achieved, and then the height adjustment of the laser beam 72 is achieved in turn.

[0022] On the basis of the above embodiment, the specific implementation of the guide beam seat 5 is as follows: the guide beam seat 5 includes a first sleeve 51, a horizontal plate 52, and a clamping plate 53. The first sleeve 51 is sleeved on the adjusting rod 4, and a first bolt 511 for pressing and fixing the first sleeve 51 on the adjusting rod 4 is arranged on the side wall of the first sleeve 51. When the first bolt 511 is rotated and tightly pressed on the side wall of the adjusting rod 4, the positioning of the first sleeve 51 is achieved. The horizontal plate 52 is horizontally fixed on the side wall of the first sleeve 51. The three clamping plates 53 are vertically arranged on the horizontal plate 52 at equal intervals along the length direction of the horizontal plate 52. The end of the guide beam 2 can be clamped between two adjacent clamping plates 53, and the upper plane of the clamping plate 53 is flush with the upper plane of the guide beam 2. In actual application, the position of the first sleeve 51 can be adjusted according to the placement requirements of the guide beam 2 so as to smoothly realize the placement of the guide beam 2.

[0023] Furthermore, based on the above embodiment, the specific implementation of the mounting base 6 is as follows: the mounting base 6 includes a second sleeve 61 and a circular plate 62, the circular plate 62 is fixedly arranged on the upper part of the second sleeve 61, the second sleeve 61 is rotatably sleeved on the upper part of the adjusting rod 4, and a second bolt 611 for pressing on the adjusting rod 4 is arranged on the side wall of the second sleeve 61, the laser emitter 7 is fixedly arranged on the circular plate 62, and through the rotation adjustment of the second sleeve 61, it is convenient to realize the smooth adjustment of the emission direction of the laser emitter 7, and then the laser beam 72 is smoothly irradiated onto the marking point 11.

[0024] In actual applications, when using the support legs 32 to adjust the horizontality of the laser emitter 7, in order to ensure the horizontal accuracy of the laser emitter 7, two bubble levels 8 distributed perpendicular to each other are provided on the circular plate 62. In the process of adjusting the support legs 32, the bubble position in the bubble level 8 is constantly referenced. When the bubbles in the two bubble levels 8 are both located in the middle, the horizontal adjustment of the circular plate 62 is achieved, thereby ensuring the horizontal adjustment of the laser emitter 7.

[0025] The process of realizing the elevation positioning of the guide beam 2 by using the utility model is as follows: first, two sets of guide beam positioning support mechanisms are erected front and back in the corresponding areas of the paved road surface. During the erection process, the support legs 32 and the bubble level 8 are used to realize the horizontal adjustment of the laser emitter 7. After the horizontal adjustment of the laser emitter 7 is completed, the first bolt 511 is used to fix the horizontal plate 52. When fixing the horizontal plate 52, the vertical distance between the upper plane of the clamping plate 53 and the laser beam 72 can be 15 cm. After the horizontal plate 52 is positioned, the corresponding receiving plate 1 is fixed on the road surface. The guide beam 2 is positioned near the steel wire 9 on the side, and the vertical distance between the marking point 11 and the upper part of the steel wire 9 is equal to the distance between the upper plane of the clamping plate 53 and the laser beam 72. After the receiving plate 1 is fixed, the two ends of the guide beam 2 are correspondingly clamped between the corresponding two clamping plates 53. Since the upper plane of the clamping plate 53 is flush with the upper plane of the guide beam 2, it is ensured that the upper plane of the guide beam 2 is flush with the upper plane of the steel wire 9. Then the guide beam 2 is used to realize the reference erection of the middle area of ​​the road surface. The guide beam 2 is distributed along the paving direction, so that the sensor of the paver is convenient to be erected thereon and move smoothly.
