[0019] 1. This utility model, by installing a hydraulic cylinder in conjunction with a push-pull bracket and connecting pipes, allows the hydraulic oil inside the hydraulic cylinder to be synchronously pressed into the telescopic cylinder. This causes the telescopic shaft inside the telescopic cylinder to extend synchronously under the action of the hydraulic oil, greatly shortening the preparation time for measurement and making the device more convenient to operate and easier to use, thus making it more user-friendly. The installation of a limiting plate allows it to be locked in the limiting groove inside the outer protrusion, fixing the position of the push-pull bracket and preventing it from moving, ensuring stability during use and enhancing the device's practicality. Simultaneously, the limiting plate has inclined surfaces on one side at both ends.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figures 1-6 One embodiment of this utility model is an RTK measuring instrument for power engineering surveying, comprising a support plate 1:

[0030] Hydraulic cylinder 7 is fixedly installed at the lower end of bearing plate 1. Installing hydraulic cylinder 7 in conjunction with push-pull bracket 10 and connecting pipe 8 allows the hydraulic oil inside hydraulic cylinder 7 to be synchronously pressed into telescopic cylinder 6. This causes the telescopic shaft 20 inside telescopic cylinder 6 to extend synchronously under the action of hydraulic oil, which greatly shortens the preparation time for workers to perform measurements, makes the device easier to operate, reduces the difficulty of using the device, and makes the device more user-friendly. Three connecting brackets 2 are fixedly installed in a ring array on the lower end face of bearing plate 1. Rotating brackets 5 are fixedly installed on the inner side of each of the three connecting brackets 2. The rotating brackets 5 and the connecting brackets 2 are rotatably connected through connecting shaft 4. The telescopic cylinder 6 is fixedly installed at the lower end of the rotating bracket 5. The telescopic shaft 20 is slidably installed inside the telescopic cylinder 6. Three connecting pipes 8 are arranged in a ring array on the upper end of the outside of hydraulic cylinder 7.

[0031] The push-pull bracket 10 is slidably installed inside the hydraulic cylinder 7. An external boss 11 is fixedly installed on the outside of the hydraulic cylinder 7. A hollow limiting shaft 15 is slidably installed inside the external boss 11. An ejector spring 19 is fixedly installed on the upper end of one side of the hollow limiting shaft 15. A limiting plate 18 is fixedly installed on one end of the ejector spring 19. Installing the limiting plate 18 allows it to be locked in the limiting groove inside the external boss 11, thereby fixing the position of the push-pull bracket 10, preventing it from moving, ensuring stability during use, and enhancing the practicality of the device. Simultaneously, the limiting plate 18 has two ends... One side of each device has a sloping surface. When the operator needs to release the limiting function of the limiting plate 18, they only need to rotate the rotating handle 14 to rotate the hollow limiting shaft 15. This causes the sloping surface on the outside of the limiting plate 18 to press against the limiting groove, thereby causing the limiting plate 18 to retract into the hollow limiting shaft 15. This allows the push-pull bracket 10 to slide up and down normally, making the device more convenient to use. The outer protrusion 11 has several limiting grooves inside. The lower end of the hollow limiting shaft 15 is fixedly installed with a rotating handle 14. The rotating handle 14 and the push-pull bracket 10 are rotatably connected through a slot.

[0032] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The limiting plate 18 has a sloping surface on one side at both ends. A ground-mounted shaft 17 is fixedly installed at the lower end of the telescopic shaft 20. A storage cylinder 16 is installed at the lower end of the telescopic shaft 20 and is fixedly connected to the telescopic shaft 20. A limiting bracket 12 is installed at the lower end of the hydraulic cylinder 7 and is fixedly connected to the hydraulic cylinder 7. A magnetic rubber pad 13 is installed on the outside of the limiting bracket 12. The magnetic rubber pad 13 fills the gap between the connecting bracket 2 and the rotating bracket 5, thereby increasing the frictional resistance of the rotating bracket 5 during rotation and preventing the need for the operator to apply a certain force during rotation, thus avoiding damage to the rotating bracket 5. The rotating bracket 5 rotates easily, which helps to enhance the stability of the device during use. The magnetic rubber pad 13 is fixedly connected to the limiting bracket 12 and magnetically connected to the telescopic cylinder 6. An anti-slip rubber pad 3 is provided between the connecting bracket 2 and the rotating bracket 5 and is fixedly connected to the connecting bracket 2. The measuring instrument body 9 is installed on the upper end of the bearing plate 1 and is connected to the bearing plate 1 through a slot. The three connecting pipes 8 are fixedly connected to the hydraulic cylinder 7 and the telescopic cylinder 6. The limiting plate 18 is connected to the hollow limiting shaft 15 through a slot. A hydraulic oil injection one-way connector 21 is fixedly installed on the upper part of the hydraulic cylinder 7.

[0033] Working principle: Before use, the operator needs to inject hydraulic oil into the telescopic cylinder 6 through the one-way connector 21. Then, during power engineering surveys, the operator simply rotates the handle 14 to rotate the hollow limit shaft 15, causing the limit plate 18 and the limit groove inside the outer protrusion 11 to be out of alignment. The operator then pushes the push-pull bracket 10 upwards, causing it to press the hydraulic oil into the telescopic cylinder 6 through the connecting pipe 8. This hydraulic oil pushes the three telescopic shafts 20 to extend synchronously into the telescopic cylinder 6. Since the hydraulic cylinder 7, connecting pipe 8, and the inside of the telescopic cylinder 6 are connected, the hydraulic cylinder 7 and connecting pipe... The hydraulic oil pressure inside the telescopic cylinder 6 and the telescopic shaft 8 is the same. Therefore, when one or two of the three telescopic shafts 20 first contact the uneven ground, the other telescopic shaft 20 that has not yet contacted the ground can continue to extend until all three telescopic shafts 20 are in contact with the ground, allowing the device to be self-adaptively placed on uneven ground. Then, the operator selects to rotate the rotating handle 14, causing the hollow limiting shaft 15 to rotate, thereby causing the limiting plate 18 to engage with the limiting groove inside the outer protrusion 11 under the action of the ejection spring 19, thus preventing the push-pull bracket 10 from sliding up and down, thus stabilizing the device. Finally, the operator can use the measuring instrument body 9 to conduct electrical engineering surveys. The pressure cylinder 7, in conjunction with the push-pull bracket 10 and connecting pipe 8, allows the hydraulic oil inside the hydraulic cylinder 7 to be synchronously pressed into the telescopic cylinder 6. This causes the telescopic shaft 20 inside the telescopic cylinder 6 to extend synchronously under the action of the hydraulic oil, significantly reducing the preparation time for measurement and making the device more convenient to operate and easier to use, thus making it more user-friendly. The installation limit clamp 18 allows it to be locked in the limit groove inside the outer protrusion 11, thereby fixing the position of the push-pull bracket 10, preventing it from moving, ensuring stability during use, and enhancing the practicality of the device. Additionally, the limit clamp 18 has a limit clamp on one side at both ends. With an inclined surface, when the operator needs to release the limiting function of the limiting plate 18, they only need to rotate the rotating handle 14 to rotate the hollow limiting shaft 15. This causes the inclined surface on the outside of the limiting plate 18 to press against the limiting groove, thereby causing the limiting plate 18 to retract into the hollow limiting shaft 15. This allows the push-pull bracket 10 to slide up and down normally, making the device more convenient to use. The installation of the magnetic rubber pad 13 can fill the gap between the connecting bracket 2 and the rotating bracket 5, thereby increasing the frictional resistance when the rotating bracket 5 rotates. This prevents the operator from having to apply a certain force when the rotating bracket 5 rotates, avoiding easy rotation of the rotating bracket 5 and enhancing the stability of the device during use.
