[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0046] like Figure 3 and Figure 4 As shown, this embodiment provides a fine adjustment machine, which is suitable for adjusting the rail row 9. The rail row 9 includes a first rail 91 and a second rail 92 arranged side by side. The outer sides of the first rail 91 and the second rail 92 are each provided with a plurality of elevation fine adjustment screws 93. A transverse fine adjustment screw 94 is provided between the first rail 91 and the elevation fine adjustment screws 93 on the outer sides thereof. The fine adjustment machine includes a traveling arm 5 of the fine adjustment machine, a beam assembly 1, an elevation fine adjustment device 3 and a transverse fine adjustment device 4. The elevation fine adjustment device 3 is connected to the beam assembly 1, and the elevation fine adjustment device 3 is used to dock with the elevation fine adjustment screw 93 to adjust the height of the first rail 91 and the second rail 92. The transverse fine adjustment device 4 is connected to the beam assembly 1, and the transverse fine adjustment device 4 is used to dock with the transverse fine adjustment screw 94 to adjust the spacing between the first rail 91 and the second rail 92. The beam assembly 1 is spaced apart from the rail row 9, and the beam assembly 1 is connected to the traveling arm 5 of the fine adjustment machine. The traveling arm 5 of the fine adjustment machine travels on the rail at one end away from the beam assembly 1.

[0047] like Figure 1 and Figure 2 As shown, the walking arm 5 of the fine adjustment machine includes a first arm 53, a second arm 54, a roller 51 and a driving member 6. The second arm 54 has a cavity, and the first arm 53 is inserted into the cavity to form a telescopic fit with the second arm 54.

[0048] The fine-tuning machine provided in this embodiment enables the beam assembly 1 to travel on the track by providing the beam assembly 1 and the walking arm 5 of the fine-tuning machine connected to the beam assembly 1. By providing the elevation fine-tuning device 3 on the beam assembly 1, the elevation fine-tuning device 3 is docked with the elevation fine-tuning screw 93 to adjust the height of the first rail 91 and the second rail 92. By providing the lateral fine-tuning device 4 on the beam assembly 1, the lateral fine-tuning device 4 is docked with the lateral fine-tuning screw 94 to adjust the spacing between the first rail 91 and the second rail 92. By providing the walking arm 5 of the fine-tuning machine including the telescopically matched first arm 53 and the second arm 54, when the beam assembly 1 travels on the track through the walking arm 5 of the fine-tuning machine, the elevation fine-tuning device 3 and the lateral fine-tuning device 4 provided on the beam assembly 1 can rise or fall in the vertical direction, so as to facilitate docking with the elevation fine-tuning screw 93 and the lateral fine-tuning screw 94.

[0049] In some embodiments, Figure 3 and Figure 4 As shown, there are multiple elevation fine-adjusting devices 3, which are spaced apart along the length direction of the rail row 9, and there are multiple walking arms 5 of the fine-adjusting machine, which are spaced apart along the length direction of the rail row 9. When the beam assembly 1 walks on the track through the walking arms 5 of the multiple fine-adjusting machines, the walking is more stable. The walking arms 5 of the multiple fine-adjusting machines are spaced apart along the length direction of the rail row 9 to better support the beam assembly 1. Along the length direction of the rail row 9, the walking arm 5 of each fine-adjusting machine is located between two adjacent elevation fine-adjusting devices 3. The walking arm 5 of the fine-adjusting machine supports the two elevation fine-adjusting devices 3 on both sides thereof, so that the elevation fine-adjusting devices 3 can work more stably.

[0050] In some embodiments, Figure 3 and Figure 4 As shown, the beam assembly 1 includes a first longitudinal beam 11, a second longitudinal beam 12, a third longitudinal beam 13 and a cross beam 14. The first longitudinal beam 11 and the second longitudinal beam 12 are arranged in parallel and side by side, and the extension direction of the first longitudinal beam 11 intersects with the extension direction of the cross beam 14. The cross beam 14 is connected between the first longitudinal beam 11 and the second longitudinal beam 12. The first longitudinal beam 11 and the second longitudinal beam 12 are both provided with an elevation fine-tuning device 3.

[0051] The third longitudinal beam 13 is connected to the cross beam 14 , and along the length direction of the cross beam 14 , the third longitudinal beam 13 is located between the first longitudinal beam 11 and the first rail 91 , and a transverse fine-tuning device 4 is provided on the third longitudinal beam 13 , and the position of the transverse fine-tuning device 4 corresponds to the position of the transverse fine-tuning screw 94 , so as to facilitate the docking of the transverse fine-tuning device 4 with the transverse fine-tuning screw 94 .

[0052] In some embodiments, Figure 3 As shown, the side of the cross beam 14 facing away from the rail row 9 is connected to the first longitudinal beam 11, and the side of the cross beam 14 facing the rail row 9 is connected to the walking arm 5 of the fine-tuning machine. The walking arms 5 of the fine-tuning machine are provided at both ends of the cross beam 14 along the length direction, so that the cross beam 14 is more stable when traveling along the length direction of the rail row 9.

[0053] In some embodiments, Figure 3 and Figure 4 As shown, there are multiple cross beams 14, which are spaced apart along the length direction of the first longitudinal beam 11, and each cross beam 14 is connected between the first longitudinal beam 11 and the second longitudinal beam 12. The first longitudinal beam 11 is provided with multiple elevation fine adjustment devices 3, which are spaced apart along the length direction of the first longitudinal beam 11, and the second longitudinal beam 12 is provided with multiple elevation fine adjustment devices 3, which are spaced apart along the length direction of the second longitudinal beam 12, and along the length direction of the first longitudinal beam 11, the walking arm 5 of each fine adjustment machine is located between two adjacent elevation fine adjustment devices 3.

[0054] The travel arm 5 of the fine adjustment machine is movably matched with the track, and the track can be the first vehicle track 91 and the second vehicle track 92, or the track can be the first running track 21 and the second running track 22. The first running track 21 is arranged on the elevation fine adjustment screw 93 outside the first vehicle track 91, and the second running track 22 is arranged on the elevation fine adjustment screw 93 outside the second vehicle track 92. The first longitudinal beam 11 is arranged in parallel with the first running track 21, and the first longitudinal beam 11 and the second longitudinal beam 12 are arranged in a one-to-one correspondence with the first running track 21 and the second running track 22. The travel arm 5 of the fine adjustment machine drives the first longitudinal beam 11 to travel on the first running rail 21 along the extension direction of the adjusted rail row 9 through the cross beam 14, and the travel arm 5 of the fine adjustment machine can be adjusted in height, so that the travel arm 5 of the fine adjustment machine adjusts the height of the first longitudinal beam 11 through the cross beam 14, that is, adjusts the elevation fine adjustment device 3 to move toward or away from the elevation fine adjustment screw 93, and the elevation fine adjustment screw 93 is connected or disconnected with the elevation fine adjustment device 3. When the elevation fine adjustment screw 93 is connected with the elevation fine adjustment device 3, the geometric state (height) of the rail row 9 is adjusted. After the adjustment is completed, the elevation fine adjustment screw 93 is disconnected from the elevation fine adjustment device 3, and the travel arm 5 of the fine adjustment machine continues to move until the elevation fine adjustment device 3 is docked with the next set of elevation fine adjustment screws 93, thereby adjusting the next section of the rail row 9. When the beam assembly 1 moves to a position and stops, the multiple elevation fine adjustment devices 3 on the first longitudinal beam 11 are docked with a set of elevation fine adjustment screws 93.

[0055] In some embodiments, Figure 3 and Figure 4 As shown, the first longitudinal beam 11 and the second longitudinal beam 12 are connected to the cross beam 14 on the side facing away from the rail row 9, and the first longitudinal beam 11 and the second longitudinal beam 12 are connected to the travel arm 5 of the fine adjustment machine (not shown in the figure) on the side facing the rail row 9. Along the length direction of the first longitudinal beam 11, the travel arm 5 of the fine adjustment machine on the first longitudinal beam 11 and the travel arm 5 of the fine adjustment machine on the second longitudinal beam 12 are alternately distributed. When the total number of the travel arms 5 of the fine adjustment machine is constant, the suspended part of the beam assembly 1 between the travel arms 5 of the two fine adjustment machines in the length direction of the rail row 9 is shortened, thereby improving the stability of the beam assembly 1.

[0056] like Figure 1 and Figure 2 As shown, this embodiment provides a walking arm 5 of a fine adjustment machine, including a first arm 53, a second arm 54, a roller 51 and a driving member 6. The second arm 54 has a cavity, and the first arm 53 is inserted into the cavity to form a telescopic fit with the second arm 54. The roller 51 is connected to an end of the second arm 54 away from the first arm 53, and the driving member 6 is connected between the first arm 53 and the second arm 54, and the driving member 6 drives the first arm 53 and the second arm 54 to move toward or away from each other.

[0057] The driving member 6 is an electric telescopic rod, a cylinder or a hydraulic cylinder, etc., which can drive the first arm 53 and the second arm 54 to move toward or away from each other.

[0058] In some embodiments, Figure 1 and Figure 2 As shown, the walking arm 5 of the fine adjustment machine also includes a rotating shaft 56, a bearing seat 57, a bearing and a motor 59. The rotating shaft 56 is inserted on the roller 51. A receiving cavity 541 is formed at one end of the second arm 54. Part of the roller 51 is located in the receiving cavity 541. The side wall of the receiving cavity 541 protects the roller 51 to prevent flying stones and other debris from falling on the roller 51, which affects the rolling and life of the roller 51. Bearings are provided at both ends of the rotating shaft 56, and each bearing is equipped with a bearing seat 57. The bearing seat 57 is connected to the second arm 54, and one end of the rotating shaft 56 extending out of the side wall of the receiving cavity 541 is connected to the motor 59.

[0059] In some embodiments, Figure 1 and Figure 2 As shown, an end surface of one end of the second arm 54 is recessed toward the other end of the second arm 54 to form a recess 542 , and recesses 542 are formed on two opposite side walls of the accommodating cavity 541 .

[0060] The bearing seat 57 includes a connecting sleeve 571 and a flange portion 572 connected to one end of the connecting sleeve 571. The connecting sleeve 571 extends along the axial direction of the rotating shaft 56. The radial direction of the flange is perpendicular to the axial direction of the rotating shaft 56. The connecting sleeve 571 is sleeved on the periphery of the rotating shaft 56. The connecting sleeve 571 is engaged with the side wall of the recess 542, so that the rotating shaft 56 and the roller 51 are rotatably connected to the second arm 54 through the connecting sleeve 571. A part of the flange is located in the recess 542, and the other part of the flange is connected to the side wall of the accommodating cavity 541 through a fastener. The connecting sleeve 571 is connected to the second arm 54 through the flange.

[0061] In some embodiments, Figure 1 and Figure 2 As shown, the motor 59 is located on the side of the second arm 54 facing the rail row 9. Avoid the motor 59 from being touched by the construction personnel on the outer side of the rail row 9.

[0062] In some embodiments, a plurality of protrusions 531 are disposed on the outer surface of the first arm 53, and the plurality of protrusions 531 are spaced apart along the length direction of the first arm 53. Compared with the contact between the cavity sidewall of the second arm 54 and the outer wall of the first arm 53, the cavity sidewall of the second arm 54 is in direct contact with the protrusions 531, which reduces the contact area between the second arm 54 and the first arm 53, thereby reducing the friction.
