Technical Field

[0001] This utility model relates to the field of power operation and maintenance protection equipment technology, specifically a power operation and maintenance protection equipment with safety protection functions. Background Technology

[0002] Power operation and maintenance is a systematic activity in which professional teams implement full-cycle management of power lines, operating equipment and power supply systems. In order to assist power operation and maintenance protection equipment in providing stable power safety protection during operation, a power operation and maintenance protection device with safety protection function is needed.

[0003] Traditional power maintenance and protection equipment typically requires the operator to stand inside the protective frame at the top of the device. The height of the protective frame is then adjusted using motors and cylinders to accommodate different line locations. However, traditional systems struggle to adjust the height of the protective plate according to the operator's height, making it difficult to ensure stable protection. Furthermore, the protective frame is prone to swaying when the operator moves inside, causing overall device instability and compromising the operator's ability to maintain stable power operations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a power operation and maintenance protection device with safety protection functions to solve the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a power operation and maintenance protection device with safety protection function, including an outer frame, an inner frame slidably connected to the inner wall of the outer frame, slots opened on the inner walls of the outer frame near the top and bottom, an auxiliary frame fixedly mounted on the inner wall of the inner frame, a square plate slidably connected to the inner wall of the auxiliary frame, a protruding rod fixedly mounted on the side of the square plate, and the outer edge of the protruding rod passing through the inner wall of the auxiliary frame and the inner wall of the inner frame and slidably sleeved with the inner wall of the slot, a limit groove opened on the side of the auxiliary frame, a sliding cylinder fixedly mounted on the bottom of the outer frame, an outer cylinder slidably sleeved on the outer edge of the sliding cylinder, a base plate fixedly mounted on the bottom of the outer cylinder, a movable base fixedly mounted on the bottom of the base plate, a cylinder fixedly mounted on the top of the movable base, and the output end of the cylinder fixedly mounted with the bottom of the base plate, and a ladder fixedly mounted on the side of the outer frame.

[0006] As a preferred embodiment of this utility model, a circular plate is fixedly mounted on the side of the square plate, and a limiting plate is rotatably connected to the side of the circular plate. The shape and size of the outer edge of the limiting plate are adapted to the shape and size of the inner wall of the limiting groove. A pull rod is fixedly mounted on the side of the limiting plate.

[0007] As a preferred embodiment of this utility model, a magnet ring is fixedly mounted at the bottom of the slide cylinder, and a coil is fixedly sleeved on the inner wall of the outer cylinder, with the inner wall of the coil slidingly sleeved with the outer edge of the magnet ring.

[0008] As a preferred embodiment of this utility model, a sliding rod is fixedly sleeved on the inner wall of the sliding cylinder near the top, and the top of the sliding rod is fixedly assembled with the bottom of the outer frame. An inner cylinder is slidably sleeved on the outer edge of the sliding rod, and the outer edge of the inner cylinder is slidably sleeved with the inner wall of the sliding cylinder.

[0009] As a preferred embodiment of this utility model, a spring is fixedly connected to the side of the square plate, and the end of the spring away from the square plate is fixedly connected to the side of the inner wall of the auxiliary frame.

[0010] As a preferred embodiment of this utility model, a positioning cylinder is fixedly assembled at the bottom of the inner wall of the outer frame, a second spring is fixedly connected to the bottom of the inner wall of the positioning cylinder, and a positioning rod is fixedly connected to the top of the second spring. The top of the positioning rod is fixedly assembled with the top of the inner wall of the inner frame. A support cylinder is fixedly assembled at the top of the movable base, and a support rod is slidably sleeved on the inner wall of the support cylinder. The top of the support rod is fixedly assembled with the bottom of the base plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This power operation and maintenance protection equipment with safety protection function uses a pull rod and a limit plate in combination. When the pull rod drives the outer edge of the limit plate through the inner wall of the limit groove to the side of the auxiliary frame, the pull rod is rotated, thereby driving the side of the limit plate to overlap with the side of the auxiliary frame. At this time, the inner wall of the groove separates from the outer edge of the protrusion. Then, the spring pushes the positioning rod on the inner wall of the positioning cylinder to move the inner frame upward, thereby rotating the pull rod in the opposite direction. Then, the protrusion is used to connect with the groove, and the auxiliary inner frame is stabilized again after adjustment inside the outer frame.

[0013] 2. This power operation and maintenance protection equipment with safety protection function uses the cooperation of the sliding cylinder and the outer cylinder. The outer edge of the sliding cylinder slides in the inner wall of the outer cylinder, and the inner wall of the sliding cylinder slides in the outer edge of the inner cylinder. In turn, the sliding cylinder drives the magnet ring to slide in the inner wall of the outer cylinder. When the outer edge of the magnet ring slides in the inner wall of the coil, the coil generates electromagnetic damping on the magnet ring, thereby assisting the outer frame and inner frame in shock absorption and thus assisting in the stable erection of the device.

A ladder 24 is fixedly mounted on the side of the outer frame 1. Through the cooperation of the square plate 5 and the protruding rod 25, the side of the square plate 5 slides in the inner wall of the auxiliary frame 4, thereby using the square plate 5 to drive the outer edge of the protruding rod 25 to pass through the inner wall of the auxiliary frame 4 and the inner wall of the inner frame 2 to connect with the inner wall of the slot 3, thereby assisting the inner frame 2 to be limited in the inner wall of the outer frame 1. Through the cooperation of the cylinder 20 and the base plate 19, the cylinder 20 pushes the base plate 19 upward on the top of the movable base 23, thereby assisting in the height adjustment of the outer frame 1 and the inner frame 2.

[0025] In a preferred embodiment, a circular plate 26 is fixedly mounted on the side of the square plate 5. A limiting plate 8 is rotatably connected to the side of the circular plate 26. The shape and size of the outer edge of the limiting plate 8 are adapted to the shape and size of the inner wall of the limiting groove 7. A pull rod 9 is fixedly mounted on the side of the limiting plate 8. Through the cooperation of the pull rod 9 and the limiting plate 8, the outer edge of the limiting plate 8 is driven by the pull rod 9 to pass through the inner wall of the limiting groove 7 to the side of the auxiliary frame 4. Then, the limiting plate 8 is rotated by the pull rod 9, and the side of the auxiliary limiting plate 8 overlaps and limits the movement with the side of the auxiliary frame 4.

[0026] In a preferred embodiment, a magnet ring 18 is fixedly mounted on the bottom of the slide cylinder 13, and a coil 17 is fixedly sleeved on the inner wall of the outer cylinder 16. The inner wall of the coil 17 is slidably sleeved with the outer edge of the magnet ring 18. Through the cooperation of the magnet ring 18 and the coil 17, when the slide cylinder 13 drives the magnet ring 18 to slide, the inner wall of the coil 17 generates electromagnetic damping on the magnet ring 18, thereby assisting the slide cylinder 13 in shock absorption.

[0027] In a preferred embodiment, a slide rod 14 is fixedly sleeved on the inner wall of the slide cylinder 13 near the top, and the top of the slide rod 14 is fixedly assembled with the bottom of the outer frame 1. The outer edge of the slide rod 14 is slidably sleeved on the inner cylinder 15, and the outer edge of the inner cylinder 15 is slidably sleeved on the inner wall of the slide cylinder 13. Through the cooperation of the slide rod 14 and the inner cylinder 15, the outer edge of the slide rod 14 slides in the inner wall of the inner cylinder 15, and then the inner wall of the slide cylinder 13 slides on the outer edge of the inner cylinder 15, thereby further assisting in limiting the movement path of the device.

[0028] In a preferred embodiment, a spring 6 is fixedly connected to the side of the square plate 5, and the end of the spring 6 away from the square plate 5 is fixedly connected to the side of the inner wall of the auxiliary frame 4. Through the cooperation of the spring 6 and the square plate 5, the spring 6 pushes the square plate 5 to move in the inner wall of the auxiliary frame 4, and then the square plate 5 drives the outer edge of the protrusion 25 to align with the inner wall of the slot 3, thereby assisting the inner frame 2 to be limited in the inner wall of the outer frame 1.

[0029] In a preferred embodiment, a positioning cylinder 12 is fixedly mounted on the bottom of the inner wall of the outer frame 1. A spring 10 is fixedly connected to the bottom of the inner wall of the positioning cylinder 12, and a positioning rod 11 is fixedly connected to the top of the spring 10. The top of the positioning rod 11 is fixedly mounted to the top of the inner wall of the inner frame 2. A support cylinder 22 is fixedly mounted on the top of the movable base 23. A support rod 21 is slidably sleeved on the inner wall of the support cylinder 22, and the top of the support rod 21 is fixedly mounted to the bottom of the base plate 19. Through the cooperation of the spring 10 and the positioning rod 11, after the inner wall of the slot 3 and the outer edge of the protrusion 25 are separated, the spring 10 pushes the positioning rod 11 upward in the inner wall of the positioning cylinder 12, thereby assisting the inner frame 2 to move upward in the inner wall of the outer frame 1. Through the cooperation of the support rod 21 and the support cylinder 22, the outer edge of the support rod 21 slides in the inner wall of the support cylinder 22, thereby further assisting in limiting the movement path of the base plate 19.

[0030] Working principle: When the device is in use, the pull rod 9 drives the outer edge of the limiting plate 8 through the inner wall of the limiting groove 7 to the side of the auxiliary frame 4. Then, the pull rod 9 is rotated, causing the side of the limiting plate 8 to engage with the side of the auxiliary frame 4. At this time, the inner wall of the groove 3 separates from the outer edge of the protrusion 25. Then, the spring 10 pushes the positioning rod 11 against the inner wall of the positioning cylinder 12, causing the inner frame 2 to move upwards. This reverses the rotation of the pull rod 9, allowing the protrusion 25 to engage with the groove 3. After the inner frame 2 is adjusted inside the outer frame 1, it is stabilized and limited again. The outer edge of the slide cylinder 13 slides in the inner wall of the outer cylinder 16, and the inner wall of the slide cylinder 13 slides in the outer edge of the inner cylinder 15. Then, the slide cylinder 13 drives the magnet ring 18 to slide in the inner wall of the outer cylinder 16. When the outer edge of the magnet ring 18 slides in the inner wall of the coil 17, the coil 17 generates electromagnetic damping on the magnet ring 18, thereby assisting the outer frame 1 and the inner frame 2 in shock absorption, and thus assisting in the stable erection of the device.
