[0016] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0017] In the related art, in the construction of transmission line wiring, the erection of electric poles is an important step. Usually, a crane is used to complete the erection of electric poles. During the construction, workers are required to use ropes to tie up the electric poles. After the poles are erected, they have to climb up to remove the ropes. The construction safety is poor and the work efficiency is difficult to improve.

[0018] The present embodiment provides a low-voltage line pole construction device for a distribution network, which improves the safety of pole construction by avoiding the removal of ropes during high-altitude operations.

[0019] See also Figure 1-Figure 4 In the present embodiment, a low-voltage line pole construction device for a distribution network includes a vehicle body 10, a boom 20 and a locking mechanism 30; wherein the boom 20 is connected to the vehicle body 10; the locking mechanism 30 is rotatably connected to the boom 20, and the locking mechanism 30 includes a cylinder 31, a center column 32 and a side column 33; the cylinder 31 is rotatably connected to the boom 20, the center column 32 is rotatably disposed inside the cylinder 31, and is transmission-connected to a driving mechanism 37, the side column 33 is rotatably disposed inside the cylinder 31, and is meshed with the center column 32, a clamping plate 34 is fixedly connected to the side column 33, the clamping plates 34 are evenly distributed along the circumference of the center column 32, the clamping plates 34 can be moved out of the cylinder 31 driven by the center column 32, and are used to fix the cylinder 31 in the center hole 41 of the pole 40.

[0020] By adopting the technical solution of this embodiment, the center column 32 is driven to rotate by the driving mechanism 37, and then the side column 33 is driven to rotate, so that the clamping plate 34 is moved out of the cylinder 31 and pressed against the inner wall of the center hole 41 of the utility pole 40, thereby fixing the cylinder 31 inside the center hole 41 of the utility pole 40. In this way, after the utility pole 40 is erected by the boom 20, it is only necessary to control the driving mechanism 37 to reverse to achieve the disengagement of the locking mechanism 30 from the utility pole 40, thereby avoiding the need to remove the rope during the climbing operation and improving the safety of the utility pole construction.

[0021] In this embodiment, the cylinder body 31 is constructed as a whole in a cylindrical shape, and a connecting cylinder 36 is fixedly connected to the top plate of the cylinder body 31, and the connecting cylinder 36 and the cylinder body 31 are arranged coaxially, the connecting cylinder 36 is rotatably connected to the end of the boom 20, and the hinge axis of the connecting cylinder 36 on the boom 20 is arranged along the diameter direction of the connecting cylinder 36, so that the locking mechanism 30 is rotatably connected to the boom 20 as a whole.

[0022] In addition, the center column 32 is rotatably connected to the inside of the cylinder 31, and the center column 32 and the cylinder 31 are coaxially arranged. The lower end of the center column 32 is rotatably connected to the bottom plate of the cylinder 31, and the upper end of the center column 32 passes through the connecting tube 36 and is connected to the driving mechanism 37 installed on the top of the connecting tube 36. As an example, the driving mechanism 37 is a motor, and the top of the center column 32 is fixedly connected to the output shaft of the motor.

[0023] In addition, the side column 33 is rotatably connected to the inside of the cylinder 31, the side column 33 is arranged parallel to the center column 32, and two side columns 33 are evenly arranged along the circumference of the center column 32. Teeth that mesh with each other are provided on the circumferential surfaces of the side column 33 and the center column 32, so that the side column 33 can rotate synchronously driven by the center column 32.

[0024] In this embodiment, the clamping plate 34 is constructed as an arc-shaped plate as a whole. The clamping plate 34 is fixedly connected to the circumferential surface of the side column 33. The clamping plate 34 extends along the axis of the side column 33. As an example, the clamping plate 34 and the side column 33 are an integrally formed structure, and an escape opening 35 is opened on the side wall of the cylinder 31. The escape opening 35 is used for the clamping plate 34 to extend out of the cylinder 31. When the center column 32 rotates, it can drive the side column 33 to rotate synchronously, and can enable the clamping plate 34 to move out of the cylinder 31 through the escape opening 35.

[0025] It should be noted that the two clamping plates 34 are rotationally symmetrical with respect to the center column 32. The two clamping plates 34 are synchronously moved out of or into the cylinder 31 under the drive of the center column 32. When the clamping plates 34 are moved out of the cylinder 31, they can abut against the inner wall of the center hole 41 of the electric pole 40. The cylinder 31 can be fixed inside the center hole 41 by utilizing the tightening effect of the two clamping plates 34. At this time, the locking mechanism 30 and the electric pole 40 are fixedly connected, and the erection of the electric pole 40 can be completed by the boom 20; after the erection of the electric pole 40 is completed, the driving mechanism 37 is controlled to reverse, so that the clamping plates 34 are separated from the side walls of the center hole 41 and then retracted into the cylinder 31. At this time, the locking mechanism 30 is separated from the electric pole 40, and the locking mechanism 30 can be directly taken out from the top of the electric pole 40 through the boom 20, avoiding the removal of ropes during climbing operations and improving the safety of electric pole construction.

[0026] Optionally, in order to increase the friction between the clamping plate 34 and the side wall of the central hole 41 , anti-slip grooves may be provided on the outer surface of the clamping plate 34 .

[0027] It should be noted that a hole-drilling mechanism 11 may be further provided on the vehicle body 10 , and the hole-drilling mechanism 11 is used to drill holes required for erecting the electric poles 40 , so as to integrate the hole-drilling function and the erecting function into an integral structure.

[0028] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
