Description

Technical Field

[0001] This invention relates to the field of power maintenance tools, and in particular to a ladder support stabilizing device and a power maintenance ladder. Background Technology

[0002] In the field of electrical maintenance technology, ladders are often used to prop up utility poles for line repairs. A ladder typically consists of two vertical bars and multiple crossbars suitable for climbing. The two vertical bars form the sides, and the crossbars are connected to the two vertical bars at their ends. Ladder stabilizing devices are components that provide additional stability and safety when using a ladder. These devices are usually installed at the top or bottom of the ladder to ensure its stability when near a utility pole.

[0003] To prevent the ladder from swaying or tilting, existing ladder stabilizing devices include a support base, a drive mechanism, and clamps. The support base is connected to the ladder, and two drive mechanisms are mounted opposite each other on the support base. Each drive mechanism is connected to two clamps, which move closer to or further apart to clamp and release the utility pole. However, existing clamp-based structures cannot guarantee a tight fit between the clamping surfaces of the clamps and the outer surface of the utility pole, resulting in poor clamping performance and failing to achieve effective stability. Summary of the Invention

[0004] The purpose of this invention is to provide a ladder support stabilizing device and an electrical maintenance ladder, which can tightly fit the clamping surface of the clamping mechanism with the outer surface of the utility pole, resulting in a good clamping effect and effective stabilization of the ladder body.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On one hand, a ladder support stabilizing device is provided for connecting the ladder body to a support rod, comprising:

[0007] A connecting mechanism for connecting the ladder body;

[0008] The clamping mechanism includes a frame, an airbag, an inflation assembly, and an exhaust assembly. The frame is disposed on the connecting mechanism and surrounds the support rod. The frame has an opening for use as an inlet for the support rod. The airbag is fixed to the inner wall of the frame and clamps the support rod. The air outlet of the inflation assembly communicates with the air inlet of the airbag, and the inflation assembly is used to inflate the airbag. The exhaust assembly is disposed at the air outlet of the airbag and is used to exhaust air from the airbag.

[0009] Preferably, the exhaust assembly includes an exhaust component and a drive component. The air inlet of the exhaust component is connected to the air outlet of the airbag, and the side wall of the exhaust component is provided with an exhaust port. The drive component is disposed on the exhaust component, and the output end of the drive component is connected to a blocking component. The drive component is used to drive the blocking component to move within the exhaust component, so that the air inlet of the exhaust component is connected to or isolated from the exhaust port of the exhaust component.

[0010] Preferably, the shielding member and the exhaust member are slidably connected along a first direction. The driving assembly includes a pulling member and a first elastic member. One end of the pulling member is fixed to the shielding member, and the other end of the pulling member passes through the side wall of the exhaust member and extends to the bottom of the ladder body. The two ends of the first elastic member are respectively connected to the exhaust member and the shielding member. When the pulling member is pulled, the exhaust port of the exhaust member can be connected to or isolated from the air inlet of the exhaust member.

[0011] Preferably, the frame includes two opposing frame bodies, with the two airbags respectively fixed to the inner walls of the two frame bodies, and at least one of the two frame bodies is adjustablely positioned on the connecting mechanism so that the two frame bodies can move closer to or further away from each other.

[0012] Preferably, the connecting mechanism includes a mounting frame and two connecting components, which are respectively disposed on opposite sides of the mounting frame and are used to connect the two vertical bars of the ladder body.

[0013] Preferably, the connecting assembly includes a first connector and a locking member. The first connector is connected to the mounting bracket and is configured to be sleeved on the outside of the vertical rod. The locking member is threadedly connected to the first connector and is used to press the vertical rod against the inner wall of the first connector.

[0014] Preferably, the connecting mechanism includes a mounting frame, and the clamping mechanism further includes an abutment. The mounting frame has a through hole on the side near the airbag. The abutment is slidably connected to the through hole, and one end of the abutment is elastically connected to the inner wall of the mounting frame. The other end of the abutment is used to abut against the support rod.

[0015] Preferably, the ladder support rod stabilizing device further includes a breaking component, one end of which is rotatably connected to the abutment component, and the other end of which is used to impact the support rod; one of the breaking component and the mounting bracket is provided with a sliding hole, and the other is provided with a sliding component, which is rotatably slidably disposed in the sliding hole.

[0016] Preferably, the ladder support stabilizing device further includes an auxiliary mechanism, which comprises a receiving member, a closing member, and a cover opening assembly. The receiving member is fixed to the mounting bracket and is used to hold tools. The closing member covers the open end of the receiving member and is slidably connected to the receiving member. The output end of the cover opening assembly is connected to the closing member, and the abutment member can drive the cover opening assembly to move, so that the closing member slides relative to the receiving member; and / or,

[0017] The ladder support device also includes a leg support assembly, which is rotatably connected to the mounting bracket. The abutment can drive the leg support assembly to rotate, and the leg support assembly can abut against the abutment.

[0018] On the other hand, an electrical maintenance ladder is also provided, including a ladder body and a ladder support stabilizing device as described in any of the above embodiments, with a connecting mechanism connected to the ladder body.

[0019] The beneficial effects of this invention are:

[0020] The ladder stabilizer provided by this invention is used to connect the ladder body to a support rod. The ladder stabilizer includes a connecting mechanism and a clamping mechanism. The connecting mechanism connects the ladder body; the clamping mechanism includes a frame, an air bladder, an inflation component, and an exhaust component. During operation, the ladder body is connected to the connecting mechanism, and then the support rod enters the frame through an opening. The inflation component then inflates the air bladder to clamp the support rod, thus stabilizing the ladder on the support rod and improving the safety of workers operating on the ladder. After operation, the exhaust component releases air from the air bladder, releasing the support rod and detaching the ladder body from the connecting mechanism. Due to the elastic properties of the air bladder, when clamping the support rod, the clamping surface of the air bladder fits tightly against the outer surface of the utility pole, resulting in a good clamping effect and effective stability for the ladder body.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0037] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0040] like Figures 1 to 8As shown, the ladder body 100 includes two vertical bars 101 and a plurality of horizontal bars 102 disposed between the two vertical bars 101. The present invention provides a ladder support stabilizing device for connecting the ladder body 100 to a support rod. The ladder support stabilizing device includes a connecting mechanism 1 and a clamping mechanism 2. The connecting mechanism 1 is used to connect the ladder body 100. The clamping mechanism 2 includes a frame 21, an airbag 22, an inflation component 23, and an exhaust component 24. The frame 21 is disposed on the connecting mechanism 1 and can surround the support rod. The frame 21 has an opening for use as an inlet for the support rod. The airbag 22 is fixed to the inner wall of the frame 21 and can clamp the support rod. The air outlet of the inflation component 23 is connected to the air inlet of the airbag 22, and the inflation component 23 is used to inflate the airbag 22. The exhaust component 24 is disposed at the air outlet of the airbag 22 and is used to exhaust the airbag 22. During operation, the ladder body 100 is connected to the connecting mechanism 1. The frame 21 rests against the support rod through its opening. Then, the airbag 22 is inflated by the inflation assembly 23 to clamp the support rod, thus stably placing the ladder body 100 on the support rod and improving the safety of workers operating on the ladder body 100. After operation, the airbag 22 is deflated by the exhaust assembly 24, releasing the support rod and disengaging the ladder body 100 from the connecting mechanism 1. Due to the elastic properties of the airbag 22, when clamping the support rod, the clamping surface of the airbag 22 fits tightly against the outer surface of the utility pole, providing a good clamping effect and effectively stabilizing the ladder body 100.

[0041] Optionally, such as Figure 3 As shown, the exhaust assembly 24 includes an exhaust component 241 and a drive assembly 242. The air inlet of the exhaust component 241 is connected to the air outlet of the airbag 22, and the side wall of the exhaust component 241 is provided with an exhaust port 2411. The drive assembly 242 is disposed on the exhaust component 241, and the output end of the drive assembly 242 is connected to a blocking component 243. The drive assembly 242 is used to drive the blocking component 243 to move within the exhaust component 241 so that the air inlet of the exhaust component 241 is connected to or isolated from the exhaust port 2411 of the exhaust component 241. Specifically, the drive assembly 242 is used to drive the shield 243 to rotate inside the exhaust component 241. For example, when the drive assembly 242 rotates forward, it drives the shield 243 to block the exhaust port 2411, thus isolating the air inlet of the exhaust component 241 from the exhaust port 2411. When the drive assembly 242 rotates in reverse, it drives the shield 243 to disengage from the shield, thus connecting the air inlet of the exhaust component 241 with the exhaust port 2411.

[0042] Alternatively, the drive assembly 242 is used to drive the blocking member 243 to slide within the exhaust member 241. Optionally, in this embodiment, the blocking member 243 and the exhaust member 241 are slidably connected along a first direction. The drive assembly 242 includes a pulling member 2421 and a first elastic member 2422. One end of the pulling member 2421 is fixed to the blocking member 243, and the other end of the pulling member 2421 passes through the side wall of the exhaust member 241 and extends to the bottom of the ladder body 100. The two ends of the first elastic member 2422 are respectively connected to the exhaust member 241 and the blocking member 243. When the pulling member 2421 is pulled, the exhaust port 2411 of the exhaust member 241 can communicate with or be isolated from the air inlet of the exhaust member 241. This design is simple in structure, allowing workers to release air from the airbag 22 by pulling the pull member 2421 after leaving the ladder body 100. This convenient operation avoids the safety hazard of releasing air from the ladder body 100 itself, which could cause the airbag 22 to lose its connection with the support rod and lead to the ladder body 100 shaking. Specifically, to release gas from the airbag 22, pull the pull member 2421, causing the blocking member 243 to slide towards the exhaust port 2411 of the exhaust member 241, thus connecting the air inlet and exhaust port 2411 of the exhaust member 241. After venting, release the pull member 2421. Due to the action of the first elastic member 2422, the blocking member 243 slides back towards the air inlet of the exhaust member 241, isolating the air inlet and exhaust port 2411 of the exhaust member 241. Optionally, the first elastic member 2422 is sleeved outside the pull member 2421. When the first elastic element 2422 is compressed, the pulling element 2421 guides the compression of the first elastic element 2422. Optionally, in other embodiments, the driving assembly 242 is an electric actuator, a cylinder, or other structure capable of driving the blocking element 243 to reciprocate within the exhaust element 241. In this embodiment, the pulling element 2421 is a pull rope, and the first elastic element 2422 is a spring.

[0043] Optionally, such as Figure 2 As shown, in this embodiment, the frame 21 includes two opposing frame bodies 211, and two airbags 22 are respectively fixed to the inner walls of the two frame bodies 211. At least one of the two frame bodies 211 is adjustablely positioned on the connecting mechanism 1 so that the two frame bodies 211 can move closer to or further away from each other. This arrangement allows the clamping mechanism 2 to be adapted to support rods of different outer diameters, stably placing the ladder body 100 on support rods of different outer diameters, and ensuring that the clamping surface of the airbag 22 can fit tightly against the outer surface of the utility pole.

[0044] In this embodiment, both skeleton bodies 211 are positionally adjustable within the connecting mechanism 1. Specifically, each skeleton body 211 has an elongated hole, the connecting mechanism 1 has an internally threaded hole, and the clamping mechanism 2 further includes a fastener 25, which passes through the elongated hole and is threadedly connected to the internally threaded hole. In other embodiments, the skeleton body 211 has multiple connecting holes, the connecting mechanism 1 has an internally threaded hole, and the fastener 25 selectively passes through one of the connecting holes and is threadedly connected to the internally threaded hole. Optionally, the fastener 25 is a bolt or a screw.

[0045] Optionally, such as Figure 2 As shown, in this embodiment, the inner cavities of the two airbags 22 are connected. One set of inflation components 23 is provided for inflating the two airbags 22, and one set of deflation components 24 is provided for defusing the two airbags 22. This arrangement saves costs. In other embodiments, the inner cavities of the two airbags 22 are not connected. Two sets of inflation components 23 are provided, each used to inflate one airbag 22. Two sets of deflation components 24 are provided, each used to defuse the two airbags 22.

[0046] Optionally, in this embodiment, the support rod is a utility pole, and the airbag 22 is made of polyurethane rubber, which is insulating and wear-resistant.

[0047] Optionally, in this embodiment, as Figure 1 As shown, the connecting mechanism 1 includes a mounting frame 11 and two connecting components 12. The two connecting components 12 are respectively disposed on opposite sides of the mounting frame 11, and are used to connect the two vertical bars 101 of the ladder body 100. This arrangement makes the connection to the ladder body 100 more reliable. In other embodiments, the connecting mechanism 1 includes one connecting component 12, which is used to connect a horizontal bar 102 of the ladder body 100.

[0048] Optionally, in this embodiment, the connecting component 12 is rotatably connected to the mounting bracket 11. This arrangement allows for easy adjustment of the angle between the ladder body 100 and the support rod after the clamping mechanism 2 clamps the support rod, making the ladder body 100 more secure and improving the safety of workers operating on the ladder body 100. Alternatively, it facilitates adjusting the position of the clamping mechanism 2 clamping the support rod.

[0049] Optionally, in this embodiment, as Figure 2As shown, the connecting assembly 12 includes a first connecting member 121 and a locking member 122. The first connecting member 121 is connected to the mounting bracket 11 and is configured to be sleeved on the outside of the vertical rod 101. The locking member 122 is threadedly connected to the first connecting member 121 to secure the vertical rod 101 against the inner wall of the first connecting member 121. When installing the ladder body 100, the two first connecting members 121 are respectively sleeved on the two vertical rods 101 of the ladder body 100, and then the locking member 122 is tightened to secure the vertical rod 101 against the inner wall of the first connecting member 121. This configuration is simple and achieves a firm connection between the ladder body 100 and the connecting mechanism 1. In addition, the connecting assembly 12 can be used to install ladder bodies 100 with vertical rods 101 of different inner diameters, improving the applicability of the device. Optionally, in this embodiment, the first connecting member 121 is rotatably connected to the mounting bracket 11 by a rivet.

[0050] Optionally, in this embodiment, as Figure 2 As shown, the inflation assembly 23 includes an air pump 231 and an air inlet pipe 232. A bracket 1211 is provided on a first connector 121, and the air inlet pipe 232 passes through the bracket 1211. The air outlet of the air pump 231 is connected to the air inlet of the air inlet pipe 232, and the air outlet of the air inlet pipe 232 is connected to the air inlet of the airbag 22. With this configuration, the inflation assembly 23 has a simple structure, and the air inlet pipe 232 passing through the bracket 1211 serves to limit its movement. In this embodiment, as... Figure 2 and Figure 3 As shown, another first connector 121 is also provided with a bracket 1211, and part of the exhaust component 241 is disposed in the bracket 1211. The bracket 1211 provided on the other first connector 121 serves to support the exhaust component 241.

[0051] The specific process of installing and disassembling the ladder body 100 using the connecting mechanism 1 and clamping mechanism 2 is as follows: Before installation, the airbag 22 is pressed tightly against the outer wall of the support rod to test the fit. If the fit is poor, the worker loosens the fasteners 25 on the frame body 211 and moves them for adjustment. After adjusting to the appropriate position, the fasteners 25 are tightened. During installation, the worker places the two first connecting pieces 121 onto the two vertical rods 101 of the ladder body 100 respectively, and then tightens the locking piece 122 to press the vertical rods 101 against the inner wall of the first connecting pieces 121. Afterward, the worker places the ladder body 100 against the support rod through the opening of the frame 21, and inflates the airbag 22 with air through the air pump 231 and air inlet pipe 232. After inflation, the airbag 22 grips the support rod, thus stabilizing the ladder body 100. During disassembly, pulling the pull member 2421 causes the blocking member 243 to slide towards the exhaust port 2411 of the exhaust member 241, thus connecting the air inlet of the exhaust member 241 with the exhaust port 2411. Releasing the pull member 2421 resets the blocking member 243, isolating the air inlet of the exhaust member 241 from the exhaust port 2411.

[0052] Optionally, such as Figure 1 and Figure 4 As shown, the connecting mechanism 1 includes a mounting frame 11, and the clamping mechanism 2 includes an abutment 26. The mounting frame 11 has a through hole 111 on the side near the airbag 22. The abutment 26 is slidably connected to the through hole 111, and one end of the abutment 26 is elastically connected to the inner wall of the mounting frame 11, while the other end of the abutment 26 abuts against the support rod. This configuration ensures a firm clamping effect between the clamping mechanism 2 and the support rod when the clamping mechanism 2 clamps the support rod, resulting in a better clamping effect and more effective stability for the ladder body 100.

[0053] Specifically, the clamping mechanism 2 further includes a guide member 27 and a second elastic member 28. The guide member 27 is fixed to the inner wall of the mounting frame 11, and the second elastic member 28 is sleeved on the outside of the guide member 27. One end of the second elastic member 28 is connected to the inner wall of the mounting frame 11, and the other end of the second elastic member 28 is connected to the abutment member 26, which is sleeved on the outside of the guide member 27. The guide member 27 is provided to guide the compression of the second elastic member 28. Further, the abutment member 26 is slidably connected to the guide member 27, and the guide member 27 provides support and guidance for the abutment member 26. In this embodiment, the second elastic member 28 is a spring.

[0054] Optionally, such as Figure 4As shown, in this embodiment, the ladder support stabilizing device further includes a breaking component 3. One end of the breaking component 3 is rotatably connected to the abutment component 26, and the other end of the breaking component 3 is used to impact the support rod. Of the breaking component 3 and the mounting frame 11, one has a sliding hole 31, and the other has a sliding member 112, which is rotatably slidably disposed within the sliding hole 31. In this embodiment, the breaking component 3 has a sliding hole 31, and the mounting frame 11 has a sliding member 112. When the ladder body 100 is placed against the support rod through the opening of the frame 21, the abutment component 26 contacts the surface of the support rod, and the abutment component 26 moves towards the mounting frame 11. When the abutment component 26 moves towards the mounting frame 11, one end of the breaking component 3 rotates relative to the abutment component 26, and the sliding member 112 on the mounting frame 11 rotatably slides within the sliding hole 31 of the breaking component 3, thereby driving the other end of the breaking component 3 to move towards the support rod, and thus impact the support rod. With this setup, when staff use the ladder body 100 in areas with a lot of ice and snow, while the ladder body 100 is placed against the surface of the support rod, the breaking component 3 breaks up part of the ice layer on the surface of the support rod. This prevents the airbag 22 from becoming unstable after contacting the support rod due to the smoothness of the ice layer, and also prevents the airbag 22 from being punctured by sharp icicles on the surface of the ice layer.

[0055] Furthermore, such as Figure 4 and Figure 5 As shown, in this embodiment, the abutment member 26 has two first connecting parts 261 arranged opposite to each other, and the clamping mechanism 2 also includes a rotating shaft 29. The crushing member 3 is rotatably connected to the two first connecting parts 261 through the rotating shaft 29. The mounting bracket 11 has two second connecting parts 113 arranged opposite to each other, and the sliding member 112 passes through the sliding hole 31, and both ends of the sliding member 112 are respectively connected to the two second connecting parts 113. This arrangement is simple in structure and convenient for installation. Further, in this embodiment, the crushing member 3 includes a curved rod 32 and an impact part 33. The impact part 33 is fixed to the tail end of the curved rod 32 and is used to impact the support rod. Further, the impact part 33 has a spherical structure, which reduces damage to the support rod while breaking ice.

[0056] Optionally, in this embodiment, as Figures 5 to 7As shown, the ladder support stabilizing device also includes an auxiliary mechanism 4. The auxiliary mechanism 4 includes a receiving member 41, a cover member 42, and a cover opening assembly 43. The receiving member 41 is fixed to the mounting bracket 11 and is used to place tools. The cover member 42 covers the open end of the receiving member 41 and is slidably connected to the receiving member 41. The output end of the cover opening assembly 43 is connected to the cover member 42. The abutment member 26 can drive the cover opening assembly 43 to move, so that the cover member 42 slides relative to the receiving member 41. When the abutment member 26 moves towards the receiving member 41, the cover member 42 slides relative to the receiving member 41, so that the cover member 42 is in an open state. Workers can place tools and accessories in the container 41 in advance. After the cover 42 is opened, since the container 41 is in front of them, it is convenient for workers to take out various tools and accessories while operating on the ladder body 100. This avoids workers having to frequently take out tools on the ladder body 100, which would increase their labor intensity. In addition, when the ladder body 100 is against the support rod through the opening of the frame 21, the cover 42 opens automatically. When the ladder body 100 is not against the support rod, the cover 42 closes automatically, which improves the automation level of the ladder support rod stabilization device.

[0057] Optionally, in this embodiment, as Figure 6 As shown, the cover opening assembly 43 includes a second connector 431 and a third connector 432. One end of the second connector 431 is rotatably connected to the receiving member 41, and one end of the third connector 432 is rotatably connected to the cover member 42. The other end of the second connector 431 is provided with a sliding hole 4311. The outer wall of the receiving member 41 is provided with a sliding groove 411. The third connector 432 is slidably connected to the sliding hole 4311 and the sliding groove 411. The abutment member 26 can abut against the second connector 431, so that the second connector 431 rotates relative to the receiving member 41 and drives the cover member 42 to slide away from the frame 21. When the abutment member 26 moves towards the receiving member 41, the abutment member 26 abuts against the second connector 431 and causes the second connector 431 to rotate, thereby driving the third connector 432 to slide in the sliding groove 411. When the third connector 432 slides, it drives the cover member 42 to slide away from the frame 21.

[0058] Optionally, in this embodiment, two of each of the second connector 431 and the third connector 432 are provided. One second connector 431 and one third connector 432 form a group, and the two groups are respectively arranged on opposite sides of the receiving member 41. The abutment member 26 is provided with a first pushing part 262, which can abut against both second connectors 431. With this arrangement, the opening effect of the cover member 42 is better.

[0059] Optionally, in this embodiment, as Figure 7As shown, the surface of the opening end of the receiving member 41 is provided with a groove 412, and the cover member 42 is provided with a corresponding protrusion. The groove 412 and the protrusion are slidably connected. This configuration results in a simple structure. Optionally, in this embodiment, the receiving member 41 is provided with multiple receiving cavities 413. Multiple receiving cavities 413 are provided for classifying and placing different types of tools, making the placement of tools and accessories more orderly and avoiding inconvenience caused by chaotic placement. Optionally, in this embodiment, the top surface of the cover member 42 is provided with multiple partitions 421 spaced apart. The multiple partitions 421 are used for temporarily placing tools and accessories. During operation, workers can place temporarily used tools or accessories between the partitions 421, further simplifying the operation. Specifically, in this embodiment, the cross-section of the partition 421 is a semi-circular structure. This configuration prevents tools from falling.

[0060] Optionally, in this embodiment, as Figure 8 As shown, the ladder support stabilizing device also includes a leg support assembly 5, which is rotatably connected to the mounting frame 11.

The rotatable connection between the leg support assembly 5 and the mounting frame 11 facilitates the storage of the leg support assembly 5. When the ladder body 100 is placed against the support rod through the opening of the frame 21, the abutment member 26 drives the leg support assembly 5 to rotate away from the support rod. When the worker is working on the ladder body 100, their legs can rest on the leg support assembly 5, which abuts against the abutment member 26. This relieves leg pressure and enhances body stability, preventing workers from experiencing leg fatigue and loss of balance due to prolonged work on the ladder body 100, thus avoiding falls.

[0061] Optionally, in this embodiment, the leg support assembly 5 includes a mounting member 51 and a leg support 52. One end of the mounting member 51 is rotatably connected to the mounting frame 11, and the leg support 52 is fixed to the other end of the mounting member 51. Optionally, there are two mounting members 51 and two leg supports 52, with one mounting member 51 and one leg support 52 forming a group. The two groups are spaced apart on the mounting frame 11. The abutment member 26 is provided with a second pushing part 263, which can abut against both mounting members 51. When the ladder body 100 is placed against the support rod through the opening of the frame 21, the second pushing part 263 drives the two mounting members 51 to rotate away from the support rod.

[0062] The present invention also provides an electrical maintenance ladder, including a ladder body 100 and a ladder support rod stabilizing device, wherein a connecting mechanism 1 is connected to the ladder body 100. When this electrical maintenance ladder is leaned against the support rod, it exhibits good stability and is not easily tipped over.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
