[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a portable power line maintenance platform with a protection function, including a base 1. A lifting frame 2 is arranged on the upper surface of the base 1. The lifting frame 2 is a prior art, through which the height of the protection platform 3 can be adjusted, and those skilled in the art can achieve it. Since it is a prior art, it will not be described in detail in this case. A protection platform 3 is arranged on the upper surface of the lifting frame 2. Maintenance personnel can stand in the protection platform 3 during maintenance. A guardrail is arranged around the protection platform 3 to ensure the safety of maintenance personnel. An adjustment component is arranged on the upper surface of the protection platform 3. A moving component is arranged on the inner wall of the base 1. The moving component includes a sliding rod 44. The sliding rod 44 can only slide upward or downward to ensure the stability of the movement of the moving frame 46. The sliding rod 44 is slidably connected through the upper surface of the base 1. A moving frame 46 is fixedly connected to the lower surface of the sliding rod 44. Multiple groups of rollers are arranged on the lower surface of the moving frame 46, which can improve the flexibility of the device. The moving frame 46 slides on the inner wall of the base 1. A support plate 45 slides on the right surface of the moving frame 46. Multiple groups of support plates 45 are arranged. When the moving frame 46 extends into the interior of the base 1, it will expand and contact the ground to increase the stability of the support. The support plate 45 is slidably connected through the right surface of the base 1.

[0032] Refer to Figure 1 - Figure 2 , the adjustment component includes a round rod 53. The round rod 53 is slidably connected through the upper surface of the protection platform 3. A protection frame 51 is fixedly connected to the upper surface of the round rod 53. The protection frame 51 can be adjusted in height through the round rod 53, providing a stable and comfortable handrail for taller maintenance workers and improving safety. A hinge block 54 is slidably connected through the lower surface of the protection frame 51. When the protection frame 51 moves, the hinge block 54 moves horizontally to the left or right, and at the same time, it rotates with the connecting rod 52 for position adjustment. The inner wall of the bottom end of the hinge block 54 is hinged with a connecting rod 52. The arranged connecting rod 52 has a certain supporting effect on the protection frame 51 to ensure the stability of the protection frame 51. The right end of the connecting rod 52 is hinged with a concave block 55, and the concave block 55 is fixedly connected to the left surface of the top end of the protection platform 3.

[0033] Refer to Figure 1 、 Figure 3 - Figure 4, at the top end of the inner wall of the base 1, there is a slider 47 elastically connected by a first spring 48. The first spring 48 always pushes the slider 47 to move leftward through its own elasticity, ensuring that when the moving frame 46 moves downward, the support plate 45 can be quickly retracted, improving the practicability. The slider 47 is fixedly connected to the upper surface of the left end of the support plate 45. One end of the first spring 48 is fixedly connected to the top end of the inner wall of the base 1, and the other end of the first spring 48 is fixedly connected to the right surface of the slider 47. On the upper surface of the base 1, there is a fixedly connected motor 41. The motor 41 is a prior art and can be realized by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. At the same time, when it stops running, the rotating shaft will be automatically locked to ensure the stability of the threaded rod 42. On the upper surface of the motor 41, there is a fixedly connected threaded rod 42. The threaded rod 42 is a prior art, which is a rod-shaped structure with threads on its outer wall. When it rotates, the structure threadedly connected to its outer wall will move linearly. On the upper surface of the slide rod 44, there is a fixedly connected connection frame 43. The threaded rod 42 passes through and is threadedly connected to the lower surface of the right end of the connection frame 43. Inside the right end wall of the moving frame 46, there is a rotatably connected roller 49. The roller 49 can reduce the friction between the moving frame 46 and the support plate 45. The roller 49 rolls on the left surface of the support plate 45. The left surface of the support plate 45 is set as an inclined surface to ensure that when the moving frame 46 moves downward or upward, it can push it to move leftward or rightward along the inclined surface.

[0034] Refer to Figure 1 - Figure 2 、 Figure 5 , the adjusting assembly further includes a connecting slide plate 56. The connecting slide plate 56 slides leftward or rightward. The connecting slide plate 56 passes through and is slidably connected to the inner wall of the protective frame 51. The front surface of the connecting slide plate 56 is fixedly connected to the rear surface of the top end of the hinge block 54. The rear surface of the connecting slide plate 56 passes through and is slidably connected with a plug rod 57. There are grooves provided on the inner wall of the protective frame 51. There are multiple groups of grooves, which are the limiting points at different heights of the protective frame 51. The front surface of the plug rod 57 contacts the inner wall of the groove. A second spring 58 is sleeved on the outer wall of the plug rod 57. The second spring 58 always pulls the plug rod 57 to move forward through its own elasticity to ensure the stability of its limit. One end of the second spring 58 is fixedly connected to the front surface of the plug rod 57, and the other end of the second spring 58 is fixedly connected to the rear surface of the connecting slide plate 56.

[0035] Working principle: When in use, when the platform needs to be parked, the motor 41 can be started to drive the threaded rod 42 to rotate. At this time, the connecting frame 43 threadedly connected to its outer wall will move linearly, and at the same time, it will drive the sliding rod 44 to move. The sliding rod 44 will drive the moving frame 46 to move upward. At this time, the base 1 will move downward relative to the moving frame 46. When the moving frame 46 moves, it will push it to move along the inclined surface of the support plate 45. The support plate 45 will drive the slider 47 to move and squeeze the spring 48. In this way, when the moving frame 46 is completely retracted into the inner wall of the base 1, the support plate 45 will be fully unfolded to increase the stability of the power line maintenance platform. When moving, start the motor 41 to drive the threaded rod 42 to rotate in the opposite direction until the moving frame 46 contacts the ground and supports the entire device to move. In this process, the support plate 45 will be reset by the elastic reverse movement of the spring 48 and retracted into the inner wall of the base 1.

[0036] When the maintenance personnel use the protection platform 3 and need to adjust the height of the protection frame 51, they can pull the plug rod 57 to disengage it from the inner wall of the groove. The plug rod 57 will stretch the spring 2 58. At this time, the protection frame 51 can be pulled to adjust its height. During the adjustment process, the hinge block 54 will slide on the inner wall of the protection frame 51, and the connecting slide 56 and the plug rod 57 will also move accordingly. At the same time, the top end of the connecting rod 52 will rotate between the hinge block 54, and the bottom end of the connecting rod 52 will rotate between the concave block 55 to adjust the position. After the adjustment is completed, loosen the plug rod 57, and the spring 2 58 will pull the plug rod 57 to move in the opposite direction through its own elasticity and insert it into the inner wall of another set of grooves.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
