[0037] See also Figure 1-10, a lofting device based on the production of ultra-high voltage transmission towers of the present invention comprises a mobile lofting vehicle 1;

[0038] A lofting rod storage assembly 2 is installed in the mobile lofting vehicle 1, and the lofting rod storage assembly 2 includes a mounting plate 21, a stepping motor 22, a rotating rod 23, a storage tray 24, a groove 25, an elastic clip 26, a hinged rod 27, an L-shaped rod 28, a fixed sliding sleeve 29, a spring 210, an L-shaped connecting plate 211 and a wedge top block 212;

[0039] A rotating rod 23 is rotatably connected inside the mobile layout vehicle 1, and a storage tray 24 is installed on the surface of the rotating rod 23. The surface of the storage tray 24 is evenly distributed with multiple grooves 25 in a ring shape, and the multiple grooves 25 opened on the surface of the storage tray 24 are all installed with a group of elastic clips 26 for clamping the layout rod.

[0041] Multiple grooves 25 opened on the surface of the storage tray 24 are all installed with fixed sleeves 29, and an L-shaped rod 28 is slidably connected in the through groove opened on the surface of the fixed sleeve 29. One end of the L-shaped rod 28 is connected to a hinge rod 27, and the other end of the hinge rod 27 is hinged to the elastic clip 26. A spring 210 is sleeved on the surface of the L-shaped rod 28, and one end of the spring 210 abuts against one side of the fixed sleeve 29, and the other end of the spring 210 abuts against the L-shaped structure of the L-shaped rod 28.

[0042] An L-shaped connecting plate 211 is installed on one side of the mounting plate 21 , and a wedge top block 212 is installed on one end of the L-shaped connecting plate 211 .

[0043] As the storage tray 24 rotates, one end of a corresponding L-shaped rod 28 can be brought into contact with the wedge top block 212, and as the storage tray 24 rotates, the wedge top block 212 can apply pressure to one end of the L-shaped rod 28, causing the L-shaped rod 28 to slide to one side and causing the spring 1 210 to compress, and one end of the L-shaped rod 28 can push the hinge rod 27, so that the two elastic clips 26 can be opened, and the angle between the two elastic clips 26 becomes larger, and the limit of the marking and setting-out rod clamped between the group of elastic clips 26 can be released, and the marking and setting-out rod moves downward under its own gravity and contacts the ground;

[0044] By setting up multiple groups of elastic clips 26, multiple groups of marking stakeout rods can be carried and stored at the same time. There is no need to carry the marking stakeout rods manually. The staff can more conveniently take the stakeout rods for use when operating the stakeout device, saving the time of taking the stakeout rods back and forth, so that the stakeout work can be carried out more quickly, speeding up the erection progress of the ultra-high voltage transmission tower and reducing the risk of loss. If the stakeout rods are carried manually, they may be left behind or lost. Through the special storage structure, the stakeout rods can be placed in a centralized manner, which is easy to manage, reduces the loss caused by loss or misplacement, and saves costs.

[0045] A lofting guide assembly 3 is installed on the surface of the rotating rod 23 and below the storage tray 24. The lofting guide assembly 3 includes a support rod 31, a slide groove 32, a sliding block 33, a fixing sleeve 34, a spring 35, an insert rod 36, a slot 37 and a guide sleeve 38.

[0046] The surface of the rotating rod 23 is evenly distributed in a ring shape with multiple support rods 31 installed, a guide sleeve 38 is provided at the end of the support rod 31, a sliding block 33 is integrally formed on the surface of the guide sleeve 38, and one end face of the support rod 31 is provided with a sliding groove 32 adapted to the sliding block 33, and the guide sleeve 38 is slidably connected to one end of the support rod 31 through the sliding block 33 and the sliding groove 32.

[0047] A fixing sleeve 34 is installed on the surface of the support rod 31, and a spring 35 is arranged inside the fixing sleeve 34. One end of the spring 35 abuts against one end of an insertion rod 36 slidably connected in the fixing sleeve 34, and the other end of the insertion rod 36 passes through the support rod 31 and is inserted into a slot 37 opened on the surface of the sliding block 33.

[0048] The marking stakeout rod can be limited in the guide sleeve 38, and the marking stakeout rod remains vertical, which can ensure the accuracy of the ground mark position, provide an accurate reference point for subsequent tower foundation construction and other links, and avoid position deviation caused by the deviation of the marking rod. The staff does not need to spend extra time to adjust the inclination angle of the marking stakeout rod. Each time the marking rod is inserted into the ground, the marking rod can be quickly in the correct vertical state, reducing the possibility of repeated operations and speeding up the progress of the entire stakeout work.

[0049] A layout marking assembly 4 is installed in the mobile layout vehicle 1, and the layout marking assembly 4 includes an L-shaped guide rod 41, a pressure plate 42, a sliding sleeve 43, a slide 44, a ball groove 45, a ball sleeve 46, a fixed slide 47, a fixed slide rod 48, a T-shaped guide rod 49, a foot pedal 410, a spring three 411 and a strip groove 412;

[0050] An L-shaped guide rod 41 is fixedly installed on the inner bottom surface of the mobile layout vehicle 1, a sliding sleeve 43 is arranged on the outer side of the L-shaped guide rod 41, a ball sleeve 46 is slidably connected to the surface of the L-shaped guide rod 41, and the ball sleeve 46 is rotatably connected in a ball groove 45 opened on the surface of the sliding sleeve 43, and a pressure plate 42 is fixedly installed at one end of the sliding sleeve 43.

[0051] A slide 44 is slidably connected in the slide sleeve 43, and the slide 44 is connected to a pedal 410 slidably connected in a groove 412 opened on the surface of the mobile lofting vehicle 1. A T-shaped guide rod 49 is slidably connected in a through hole opened on the surface of the slide 44, and one end of the T-shaped guide rod 49 is fixedly mounted on the inner bottom surface of the mobile lofting vehicle 1. A spring three 411 is sleeved on the surface of the T-shaped guide rod 49, and one end of the spring three 411 abuts against the inner bottom surface of the mobile lofting vehicle 1, and the other end of the spring three 411 abuts against the bottom surface of the slide 44.

[0052] The pressure plate 42 can be brought into contact with the end of the marking rod and pressurize the marking rod so that the marking rod is inserted into the ground, making it more convenient to use the marking rod, improving the flexibility of the device, and maintaining the depth of the marking rod inserted into the soil, thereby avoiding the phenomenon of the marking rod tipping over when the insertion depth is shallow, thereby ensuring the layout quality of the erection of the UHV transmission tower.

[0053] A fixed slide 47 is integrally formed on the surface of the slide 44 . A fixed slide rod 48 is slidably connected in a through hole provided on the surface of the fixed slide 47 . The fixed slide rod 48 is fixedly mounted on the inner wall of the mobile lofting vehicle 1 .

[0054] The present invention provides a layout device based on the production of ultra-high voltage transmission towers through improvement, and its working principle is as follows:

[0055] First, when using the device, first of all, when using it, first push the mobile layout vehicle 1 to move the device to the area where layout is required. When it is necessary to insert a benchmark for layout marking, start the stepper motor 22, so that the rotating rod 23 connected to the output shaft end of the stepper motor 22 drives the storage tray 24 to rotate intermittently at equal intervals. As the storage tray 24 rotates, one end of a corresponding L-shaped rod 28 can be brought into contact with the wedge top block 212, and as the storage tray 24 rotates, the wedge top block 212 can apply pressure to one end of the L-shaped rod 28, causing the L-shaped rod 28 to slide to one side and causing the spring 1 210 to compress, and one end of the L-shaped rod 28 can push the hinge rod 27, so that the two elastic clips 26 can be opened. At this time, the angle between the two elastic clips 26 becomes larger, and the limit of the marking layout rod clamped between this group of elastic clips 26 can be released, and the marking layout rod moves downward under its own gravity to contact the ground;

[0056] Second, by providing multiple sets of elastic clips 26, multiple sets of marking stakeout rods can be carried and stored at the same time. There is no need to carry the marking stakeout rods manually. When operating the stakeout device, the staff can more conveniently take the stakeout rods for use, saving the time of taking the stakeout rods back and forth, so that the stakeout work can be carried out more quickly, speeding up the erection progress of the ultra-high voltage transmission tower, and reducing the risk of loss. If the stakeout rods are carried manually, they may be left behind or lost. Through the special storage structure, the stakeout rods can be placed in a centralized manner, which is convenient for management, reduces the loss caused by loss or misplacement, and saves costs;

[0057] Third, while the storage tray 24 is rotating intermittently at equal intervals, the support rod 31 fixedly mounted on the outside of the rotating rod 23 can rotate accordingly, so as to ensure that after the limit of the marking and setting out rod is released, the freely falling marking and setting out rod can vertically fall into the corresponding guide sleeve 38, and the marking and setting out rod can be limited in the guide sleeve 38 at this time, and the marking and setting out rod remains vertical, which can ensure the accurate position of the ground mark, provide an accurate reference point for subsequent tower foundation construction and other links, avoid position deviation caused by the deflection of the marking rod, and the staff does not need to spend extra time to adjust the inclination angle of the marking and setting out rod. Each time the marking rod is inserted into the ground, the marking rod can be quickly in the correct vertical state, which reduces the possibility of repeated operations and speeds up the process of the entire setting out work;

[0058] Fourth, after the marking stakeout rod is limited by the guide sleeve 38, the construction personnel can step on the pedal 410, so that the slide 44 installed at one end of the pedal 410 will follow the downward movement, which can drive the slide sleeve 43 slidably connected to the surface of the slide 44 to follow the downward movement, and under the action of the set ball sleeve 46 and the ball groove 45, the slide sleeve 43 can be guided by the L-shaped guide rod 41 while following the downward movement. The slide sleeve 43 can slide on the surface of the slide 44 to compensate for the displacement. When the slide sleeve 43 moves to the vertical position of the L-shaped guide rod 41, the slide sleeve 43 connected to the slide sleeve 43 is connected to the slide sleeve 43. The pressure plate 42 at one end of the sleeve 43 can be located just above a marking and setting-out rod in contact with the ground. As the sliding sleeve 43 continues to move, the pressure plate 42 can abut against the end of the marking and setting-out rod and apply pressure to the marking and setting-out rod, so that the marking and setting-out rod is inserted into the ground, making it more convenient to use the marking and setting-out rod, improving the flexibility of the device, and maintaining the depth of the marking and setting-out rod inserted into the soil, avoiding the phenomenon that the marking and setting-out rod falls over when the insertion depth is shallow, thereby ensuring the setting-out quality of the erection of the UHV transmission tower.

[0059] As the pressure plate 42 moves downward, the marking layout rod can drive the guide sleeve 38 to move downward, so that the sliding block 33 connected to one side of the guide sleeve 38 moves downward in the sliding groove 32 opened on the surface of the support rod 31. When moving downward, the downward force of the pressure plate 42 is greater than the elastic force of the spring 2 35 itself, so that one end of the insertion rod 36 elastically connected by the spring 2 35 can be disengaged from the slot 37 opened on the surface of the sliding block 33. When the marking layout rod is inserted into the ground, the guide sleeve 38 and the sliding block 33 on the outside of the marking layout rod can be disengaged from one end of the support rod 31, follow the marking layout rod to move downward, and remain on the ground, ensuring that when the marking layout rod is moved down and inserted to layout the mark, the marking layout rod can always be guided to prevent it from being deflected, thereby ensuring the accuracy of the layout.
