[0002] During the construction of new transmission lines, in order to prevent the two ends of the conductor from vibrating due to wind, it is necessary to install anti-vibration hammers at the antinodes of the conductor vibration waves. In addition, during the installation of multiple split conductors, in order to constrain the spacing between each harness to meet the electrical performance and reduce the surface potential gradient, and to avoid the generation of electromagnetic force causing mutual attraction and collision, it is necessary to install spacers at a certain distance on the conductor. There are strict requirements for the distance from the anti-vibration hammer to the tower head, and there are also distance requirements for the spacing of the spacers. This requires that the installation position be measured and marked in advance before the installation work, and then various installation operations can be carried out.

All other embodiments obtained by those skilled in the art without creative work on the basis of the embodiments of the present application shall belong to the protection scope of the present application.

[0045] For the convenience of description, the coordinate system is defined as Figure 1 As shown, the left-right direction is the horizontal direction, the front-back direction is the longitudinal direction, and the up-down direction is the vertical direction.

[0046] Embodiment 1

[0047] A tower-free marking device for power transmission line construction work includes an operating unit and a ground monitoring terminal (not shown in the figure). The operating unit is used to automatically walk on the power transmission line and perform marking operations at a preset position. The ground monitoring terminal is used to receive and display the operating data of the operating unit in real time, and control the operating status of the operating unit through a communication system.

[0048] like Figure 1 , Figure 2 and Figure 8 As shown, the operating unit includes a main frame 1 and a chassis 2, and the chassis 2 is fixedly arranged at the lower end of the main frame 1 in a detachable manner. A battery (not shown in the figure), a controller (not shown in the figure) and a communication system (not shown in the figure) are arranged in the chassis 2. The battery is used to provide power for the operation of the operating unit, the controller is used to control the operation of the operating unit, and the communication system is used to transmit the status parameters and inspection data of the operating unit to the ground monitoring terminal, and can receive and execute the control instructions of the ground monitoring terminal.

[0049] As a specific implementation, the communication system described in this embodiment includes WiFi and LoRa antennas.

[0050] The main frame 1 is provided with two walking parts 3, and the walking parts 3 include walking wheels 32 and a motor for driving the walking wheels 32 to rotate. The walking wheels 32 are hooked on the wire 7 and can move along the wire 7 driven by the motor.

[0051] A clamping component 4 is provided between the two walking components 3, and the clamping component 4 includes a clamping wheel 43, and the clamping wheel 43 clamps the wire 7 from bottom to top. The wire 7 is clamped between the walking wheel 32 and the clamping wheel 43, which can provide a locked safety protection to prevent the operating unit from falling off the wire 7; on the other hand, it can provide a certain reverse pressure, thereby increasing the contact pressure between the walking wheel 32 and the wire 7, and improving the driving force of the overall walking and climbing of the operating unit.

[0052] A marking component 5 is provided on the main frame 1 between the two walking components 3, and an RTK positioning antenna 6 is provided on the main frame 1. The RTK positioning antenna 6 can locate and measure the longitude, latitude and elevation coordinates of the working unit, and is used for the motion navigation and measurement of the working unit to locate the working unit. The controller can autonomously locate according to the preset position based on the feedback positioning information, and control the marking component 5 to perform the marking operation, thereby realizing automatic positioning and marking of the working unit.

[0053] As a specific implementation method, Figure 2 and Fig.15 As shown, the main frame 1 described in this embodiment includes a top plate 11, and a first vertical plate 12 extending downward is provided on one side of the top plate 11, and two groups of parallelly arranged walking parts 3 are provided on the first vertical plate 12. The motor of the walking part 3 is fixedly provided on the first vertical plate 12 in a detachable manner, and the power output end of the motor faces the other side opposite to the first vertical plate 12. Exemplarily, the first vertical plate 12 is provided on the left side of the top plate 11, and the power output end of the motor faces the right side of the top plate 11.

[0054] Furthermore, if Figure 3 , Figure 5 and Fig.14 As shown, the motor adopts a direct drive motor 31, and the outer stator 311 of the direct drive motor 31 is fixedly connected to the first vertical plate 12 by screws, and the walking wheel 32 is fixedly connected to the inner rotor 312 of the direct drive motor 31 in a detachable manner.

[0055] Furthermore, if Figure 2 , Figure 5 and Fig.14As shown, the top plate 11 is provided with a second vertical plate 13 extending downward, the second vertical plate 13 is parallel to the first vertical plate 12, and the walking wheel 32 is located between the first vertical plate 12 and the second vertical plate 13. In order to increase the friction force of the walking wheel 32 when walking, the walking wheel 32 is made of a rubber material with a large friction coefficient. The walking component 3 also includes a clamping plate 33 coaxially arranged with the walking wheel 32, the clamping plate 33 is connected to the inner rotor 312 of the direct drive motor 31 through a bolt 34, the walking wheel 32 is located between the inner rotor 312 of the direct drive motor 31 and the clamping plate 33, and the walking wheel 32 is provided with a first mounting through hole 321 for accommodating the bolt 34. Under the locking force of the bolt 34, it is clamped and fixed between the inner rotor 312 of the direct drive motor 31 and the clamping plate 33. As a specific embodiment, in this embodiment, a plurality of bolts 34 used to connect the clamping plate 33 and the inner rotor 312 are evenly arranged along the circumferential direction. A first shaft 331 is disposed on a side of the pressing plate 33 facing away from the traveling wheel 32 , and the first shaft 331 is rotatably connected to the second vertical plate 13 via a bearing assembly.

[0056] Furthermore, if Figure 5 and Fig.14 As shown, a second shaft 332 extending perpendicularly to the clamping plate toward the first vertical plate 12 is provided on the side of the clamping plate 33 facing the walking wheel 32, and the end of the second shaft 332 passes through the walking wheel 32 and is inserted into the plug hole 3121 of the inner rotor 312 of the direct drive motor 31. The walking wheel 32 is provided with a second mounting through hole 322 for accommodating the second shaft 332.

[0057] The reason for such design is that by setting the second vertical plate 13 and the clamping plate 33, and making the clamping plate 33 rotatably connected to the second vertical plate 13, the cantilever state of the running wheel 32 can be avoided during operation, and the bending moment applied to the direct drive motor 31 can be reduced, which is beneficial to protecting the direct drive motor 31. By setting the second shaft 332 on the clamping plate 33, and inserting the second shaft 332 into the inner rotor 312 of the direct drive motor 31, the stress state of the running wheel 32 can be improved. Since the running wheel 32 is made of a rubber material with a large friction coefficient, although it is beneficial to improve the creeping force, the rubber material is soft, so the deformation degree of the running wheel 32 will also be increased. By setting the second shaft 332, the overall weight of the working unit is mainly borne by the rigid clamping plate 33, the first shaft 331 and the second shaft 332 (the three are an integrated structure), and will not be applied to the running wheel 32, so the deformation of the running wheel 32 can be reduced.

[0058] Furthermore, in order to reduce the weight of the operating unit, a first weight-reducing hole 131 is provided on the second vertical plate 13 .

[0059] Furthermore, if Figure 5 and Fig.14 As shown, a first baffle 35 coaxially arranged with the walking wheel 32 is provided on one side of the walking wheel 32 close to the direct drive motor 31, and a second baffle 36 coaxially arranged with the walking wheel 32 is provided on one side of the walking wheel 32 close to the second vertical plate 13, and the outer diameters of the first baffle 35 and the second baffle 36 are both larger than the outer diameter of the walking wheel 32. The first baffle 35 and the second baffle 36 are both made of insulating material. Exemplarily, the first baffle 35 and the second baffle 36 are made of nylon or plastic. The first baffle 35 and the second baffle 36 can block the wire 7, improve the safety of the operating unit during operation, and prevent the walking wheel 32 from deviating from the wire 7 and slipping during walking.

[0060] As a specific implementation, the first baffle plate 35 described in this embodiment is pressed between the running wheel 32 and the inner rotor 312 of the direct drive motor 31, and the first baffle plate 35 is provided with a first avoidance hole 351 for accommodating the second shaft 332 and a second avoidance hole 352 for accommodating the bolt 34.

The second baffle plate 36 is fixedly connected to the running wheel 32 by screws, and a threaded hole 323 matching with the screw is provided on the side of the running wheel 32 facing the second vertical plate 13.

[0061] Furthermore, a plurality of second weight-reducing holes are disposed on the first baffle plate 35 and the second baffle plate 36 , and the plurality of second weight-reducing holes are evenly arranged along the circumferential direction.
