Description

Technical Field

[0001] This utility model relates to the technical field of power construction equipment, and in particular to a power engineering construction ladder. Background Technology

[0002] Power engineering involves various operational stages, including transmission line erection, equipment installation, and routine maintenance. In these stages, workers often need to operate at heights or between different heights. Construction ladders play a crucial role in power engineering, assisting workers in reaching these heights. Their structure is generally lightweight and stable, enabling workers to quickly reach their work positions and ensuring safety and flexibility during operations to a certain extent.

[0003] Most existing construction ladders only provide access to heights, requiring workers to carry tools or rely on ground-based support personnel to deliver them. This not only increases inconvenience during construction but also creates situations where tools are temporarily unavailable. Frequent climbing up and down the ladder to retrieve tools is not only physically and time-consuming but also poses safety hazards due to limited mobility at heights. Furthermore, existing construction ladders generally lack functional designs that integrate tool storage and adjustable positions, failing to flexibly adjust tool storage locations according to the user's climbing height. This severely impacts the continuity and efficiency of construction. Therefore, a new type of construction ladder for power engineering is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a construction ladder for power engineering, which aims to improve the problem of low efficiency caused by construction workers having nowhere to put tools or having to frequently go up and down to retrieve them when working at heights.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a power engineering construction ladder, comprising a telescopic ladder, the telescopic ladder being composed of a fixed ladder and a sliding ladder, which are slidably connected, a side rod being fixedly connected to the side wall of the sliding ladder, a storage box being provided on the outside of the side rod, a positioning mechanism being provided inside the side rod, a hook plate being provided on the top of the sliding ladder, and an adjustment mechanism being provided between the sliding ladder and the hook plate; The positioning mechanism includes a collar and a slider. The collar is slidably connected to the side wall of the side rod. A sleeve is fixedly connected inside the side rod. The side wall of the slider is slidably connected to the inside of the sleeve. A first spring is provided inside the sleeve. The side wall of the slider is slidably connected to the inside of the collar. The storage box is fixedly connected to the side wall of the collar.

[0006] The above technical solution provides a telescopic ladder that is structurally stable, easy to use, and has positioning and adjustment functions, which can effectively improve the safety and efficiency of construction workers.

[0007] Preferably, one end of the first spring is fixedly connected to the inside of the sleeve, and the other end of the first spring is fixedly connected to the side wall of the slider.

[0008] The above technical solution achieves the goal of using the elastic reset effect of the first spring to enable the slider to be stably limited and reset.

[0009] Preferably, a handle is fixedly connected to the side wall of the collar, and multiple anti-slip strips are fixedly connected to the side wall of the handle.

[0010] The above technical solution makes it easier for construction workers to grip and operate the collar, and the anti-slip strip can increase friction, prevent slipping when wet or when operating with gloves, and improve safety.

[0011] Preferably, a sliding groove is provided through one side of the side rod along the axial direction, and the inner wall of the collar is slidably connected inside the sliding groove.

[0012] The above technical solution enables the collar to slide stably along the groove, avoids jamming, and improves the overall structural stability.

[0013] Preferably, the adjusting mechanism includes a toothed plate one and a toothed plate two, which mesh with each other. A fixed sleeve is fixedly connected to the top of the sliding ladder. The toothed plate one is fixedly connected to the opening side of the fixed sleeve. The toothed plate two is slidably connected inside the fixed sleeve. A sliding rod is fixedly connected to the center of the side of the toothed plate two near the toothed plate one. The side wall of the sliding rod is slidably connected inside the toothed plate one. The hook plate is fixedly connected to the sliding rod.

[0014] The above technical solution achieves precise adjustment of the position between the sliding ladder and the hook plate through toothed plate engagement, ensuring the hook is stable and secure.

[0015] Preferably, a second spring is provided inside the fixing sleeve, one end of the second spring is fixedly connected to the inner wall of the fixing sleeve, and the other end of the second spring abuts against the toothed plate.

[0016] The above technical solution achieves the goal of providing elastic preload through the second spring, enabling the second toothed plate to reliably engage with the first toothed plate, preventing loosening, and enhancing the reliability of the adjustment mechanism.

[0017] Preferably, a limiting ring is fixedly connected to the side wall of the slide bar, and the limiting ring is disposed at the top of the toothed plate.

[0018] The above technical solution achieves the goal of using a limiting ring to limit the slide bar and prevent excessive movement of the toothed plate.

[0019] This utility model has the following beneficial effects: 1. In this utility model, the toolbox position can be easily and conveniently adjusted according to the worker's climbing height through the cooperation of the collar, storage box, slider and first spring. This solves the problem of tools having nowhere to be placed or needing to be frequently picked up and down when working at height, which affects efficiency and even causes safety hazards. It improves the convenience and work efficiency of workers when performing work at height.

[0020] 2. In this utility model, the cooperation between the hook plate, the slide rod, the first toothed plate, the second toothed plate and the second spring achieves the effect of quickly adjusting and stably locking the suspension angle, which solves the problem of unstable connection or inability to use caused by the fixed angle of the traditional hook and its difficulty in adapting to different suspension points, and improves the applicability and safety of the equipment when working at height.

[0023] Reference Figures 1-4This utility model provides an embodiment of a power engineering construction ladder, including a telescopic ladder 1. The telescopic ladder 1 consists of a fixed ladder 101 and a sliding ladder 102, which are slidably connected. This slidable connection is achieved by setting a sliding groove and guide block, or by a sleeve connection, allowing the sliding ladder 102 to extend and retract along the axial direction of the fixed ladder 101, thereby adjusting the ladder height. A locking mechanism is provided between the fixed ladder 101 and the sliding ladder 102 to fix them after they have been adjusted to a preset height. The locking mechanism adopts a pin-type structure, that is, the fixed ladder 101 is provided with several positioning holes, and the sliding ladder 102 is provided with a pin. When the sliding ladder... After 102 is extended to the target position, it is reliably locked by inserting a pin into the corresponding positioning hole, thereby preventing accidental displacement of slide ladder 102 during use. The telescopic ladder 1 is existing technology and will not be described in detail here. A side rod 2 is fixedly connected to the side wall of slide ladder 102. The side rod 2 is connected to the side wall of slide ladder 102 by welding. A storage box 5 is set on the outside of the side rod 2. The side rod 2 is used to support and install the positioning mechanism and the storage box 5, ensuring the stability and reliability of the entire structure. A positioning mechanism is set inside the side rod 2. A hook plate 17 is set on the top of slide ladder 102. An adjustment mechanism is set between slide ladder 102 and hook plate 17. The positioning mechanism includes a collar 4 and a slider 9. The collar 4 is slidably connected to the side wall of the side rod 2. The collar 4 is a hollow ring structure, and its inner wall size is adapted to the outer wall size of the side rod 2. It is slidably sleeved on the outside of the side rod 2. A sleeve 7 is fixedly connected inside the side rod 2. The side wall of the slider 9 is slidably connected inside the sleeve 7. The sleeve 7 is used to guide the linear movement of the slider 9. A first spring 8 is set inside the sleeve 7. The side wall of the slider 9 is slidably connected inside the collar 4. The slider 9 can reciprocate in the sleeve 7. Its protruding end can be engaged with the positioning hole preset in the collar 4. The storage box 5 is fixedly connected. The storage box 5, attached to the side wall of the collar 4, can be used to store small construction tools or spare parts such as wrenches, screwdrivers, and insulating tape, making it convenient for workers to access them at any time on the ladder. This avoids the risk of tools scattering and improves the convenience and safety of working at height. One end of the first spring 8 is fixedly connected to the inside of the sleeve 7, and the other end of the first spring 8 is fixedly connected to the side wall of the slider 9. The first spring 8 works with the slider 9 to compress and rebound. Its elastic force continuously pushes the slider 9 toward the locking position, achieving the effect of automatic locking when there is no external force, preventing the storage box 5 from accidentally sliding due to misoperation or vibration. A handle 6 is fixedly connected to the side wall of the collar 4, and multiple anti-slip strips 10 are fixedly connected to the side wall of the handle 6. The handle 6 provides a point of leverage for the operator. By pulling the handle 6, the collar 4 can be moved easily, thereby controlling the slider 9 to disengage from the positioning hole, realizing the quick unlocking and adjustment of the height of the storage box 5. A groove 3 is opened through one side along the axial direction inside the side rod 2. The inner wall of the collar 4 is slidably connected inside the groove 3. The guide ribs on the inner wall of the collar 4 cooperate with the groove 3 to guide the sliding, effectively preventing the collar 4 from rotating on the side rod 2, ensuring that it can only make smooth linear movements, and ensuring that the slider 9 can be accurately aligned with the positioning hole.

[0024] Reference Figure 1 and Figure 5 The adjusting mechanism includes a first toothed plate 12 and a second toothed plate 13, which mesh with each other. A fixed sleeve 11 is fixedly connected to the top of the sliding ladder 102. The base of the fixed sleeve 11 is firmly installed on the top of the sliding ladder 102 by welding. The first toothed plate 12 is fixedly connected to the opening side of the fixed sleeve 11 by welding, forming an end cap structure with a central hole. The end face of the first toothed plate 12 near the second toothed plate 13 has radial teeth for meshing with the teeth of the second toothed plate 13. The mechanism uses mechanical interlocking between the teeth to rigidly fix the rotation angle of the hook plate 17. The second tooth plate 13 is slidably connected inside the fixed sleeve 11. A sliding rod 15 is fixedly connected to the center of the second tooth plate 13 near the first tooth plate 12. The side wall of the sliding rod 15 is slidably connected inside the first tooth plate 12. The hook plate 17 is fixedly connected to the sliding rod 15. The hook plate 17 is used to hook onto the crossarm of the utility pole, cable or other stable structure to reliably fix the top of the ladder, thereby providing workers with an extremely stable working platform and improving the safety of high-altitude operations. The fixed sleeve 11 is equipped with a second spring 14. The toothed plate 13 slides axially with the fixed sleeve 11. Under the action of external force, it can overcome the elastic force of the second spring 14 and move, achieving the effect of separation or engagement of its tooth profile with the tooth profile of the toothed plate 12. One end of the second spring 14 is fixedly connected to the inner wall of the fixed sleeve 11, and the other end of the second spring 14 abuts against the toothed plate 13. The second spring 14 works with the toothed plate 13. Its continuously applied elastic force can ensure that the toothed plate 13 is always tightly engaged with the toothed plate 12 in the default state, achieving the effect of automatic angle locking and avoiding accidental angle changes due to vibration and other reasons. The side wall of the slide rod 15 is fixedly connected to a limit ring 16. The limit ring 16 is set on the top of the toothed plate 12 and is used to limit the axial movement of the slide rod 15.

[0025] Working principle: When using this device, first adjust the angle of the hook plate 17 according to the angle of the upper suspension point. By pressing the hook plate 17, press the slide rod 15 into the inside of the fixed sleeve 11 until the limiting ring 16 is in contact with the upper surface of the toothed plate 12. When the slide rod 15 moves downward, the toothed plate 13 will move downward synchronously and separate from the toothed plate 12. At the same time, it will squeeze the second spring 14 to deform it. At this time, the hook plate 17 can be twisted to change its orientation so that the hook plate 17 can be engaged with the upper suspension point. After the orientation angle of the hook plate 17 is determined, gradually release the hook plate 17 so that the second spring 14 begins to reset and pushes the toothed plate 13 upward to engage with the toothed plate 12, ensuring the stability of the hook plate 17. Then the hook plate 17 can be connected to the suspension point. After the telescopic ladder 1 is fixed, the workers can place the tools used for construction inside the storage box 5. While climbing, the workers hold the handle 6 and move the collar 4 upward. As the collar 4 moves, it will squeeze the slider 9 into the sleeve 7, causing the first spring 8 to deform under force. When the workers climb to the appropriate height, the collar 4 will move to the outside of the corresponding slider 9. When the groove inside the collar 4 is aligned with the slider 9, the first spring 8 will lose pressure and push the slider 9 to return to its original position, locking the slider 9 inside the collar 4. This fixes the height of the storage box 5 so that the workers can access the tools for work.
