Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] See Figure 1 This embodiment relates to a mobile safety ladder for equipment maintenance, comprising a ladder frame 2 with a movable ladder base 1 at the bottom, a maintenance platform 3 at the top of the ladder frame 2, and a ladder track 4 on the ladder frame 2 connected to the maintenance platform 3 and the movable ladder base 1, and a plurality of sets of steps 40 arranged at intervals on the ladder. The mobile safety ladder body 100 is provided with a lifting component 5. The lifting component 5 includes a connecting seat 51 installed on the ladder frame 2 located on the maintenance platform 3 and a connecting shaft 52 rotatably installed on it, and a storage box 53 located above the movable ladder base 1. A connecting rope 54 is provided between the connecting shaft 52 and the storage box 53, and a drive component 6 for winding the connecting rope 54 is provided on the connecting shaft 52.

[0021] Specifically in this embodiment, such as Figure 1 The overall structure of this mobile safety ladder for equipment maintenance is designed based on the common mobile safety ladders in the prior art. The main body 100 of this mobile safety ladder, with a certain height, is designed accordingly. The main body 100 of this mobile safety ladder is moved and adjusted to different positions via multiple sets of casters 11 and support legs 12 installed at the bottom of the ladder base 1, providing stable support for corresponding positions during maintenance. Maintenance personnel can climb to the maintenance platform 3 at the top of the ladder frame 2 via the ladder 4 and the several sets of steps 40 arranged at intervals to perform subsequent maintenance on the equipment at the corresponding height. However, unlike traditional mobile safety ladders, this mobile safety ladder 100 has a lifting assembly 5 installed on its main body. In the early stages of use, the connecting seat 51 can be installed using bolts. Figure 1On the ladder frame 2, for example, the connecting rope 54 is set to an appropriate length according to the specific height of the maintenance platform 3, and one end can be threaded and tied through the through slot 521 on the connecting shaft 52. After the connecting rope 54 is tied, it can be wound and unwound on the connecting shaft 52 by the drive component 6. During unwinding, the other end of the connecting rope 54, which moves downward below the maintenance platform 3, can be connected to the storage box 53 located above the movable ladder base 1. Specifically, it is tied around the storage box 53 by the handle 530 provided on the top of the storage box 53. When maintenance personnel on the maintenance platform 3 need to transfer maintenance tools or parts during actual maintenance, they can operate the drive component 6 to rotate the connecting shaft 52 and cause the connecting rope 54 on the connecting shaft 52 to unwind or wind up. This allows the storage box 53 to slide up and down between the maintenance platform 3 and the movable ladder 1. Specifically, this can be done in coordination with operators on the ground to transfer maintenance tools or parts by taking them out and replacing them through the storage box 53. Compared to the traditional structure of mobile safety ladders, the main body 100 of this mobile safety ladder features a lifting assembly 5 that allows for convenient vertical transfer of maintenance tools, disassembled parts, and replacement components according to maintenance needs. This offers higher transfer efficiency, ease of operation, and safety compared to manual climbing. Furthermore, the storage box 53 can be configured with different sizes or components of corresponding dimensions can be directly tied to one end of the connecting rope 54 to meet various transfer requirements and flexibility. The connecting rope 54 can also be configured or replaced with different rope structures, such as nylon rope or steel wire rope, depending on the weight of the components to be transferred, improving transfer stability, safety, and applicability. Additionally, the overall structure of the lifting assembly 5 is relatively simple, which can appropriately reduce its operating costs. While facilitating operation and maintenance, it further enhances the functionality, flexibility, and applicability of this mobile safety ladder.

[0022] The drive assembly 6 is configured with a handle 61 detachably mounted on one end of the connecting shaft 52, a gear 62 mounted on the other end of the connecting shaft 52, and a locking member 63 rotatably mounted on the connecting seat 51 on one side of the gear 62 for engaging the gear 62. See details for further information. Figure 2As shown, the handle 61 is L-shaped and passes through multiple through holes 522 at one end of the connecting shaft 52. A bolt connecting piece rotatably mounted on one end of the handle 61 is detachably installed on the connecting shaft 52. The corresponding gear 62 can be sleeved on the other end of the connecting shaft 52. A locking piece 63, under the action of a pin 631 and its torsion spring, is rotatably mounted on the connecting seat 51 and can engage the gear 62 in the corresponding helical direction. In actual use, maintenance personnel can rotate the handle 61 to drive the connecting shaft. Rotating the handle 52 allows for the winding or unwinding of the connecting rope 54, facilitating the vertical transfer of maintenance tools or parts through the storage box 53. Simultaneously, the rotating handle 61 drives the gear 62 at the other end of the connecting shaft 52 to rotate synchronously. Combined with the function of the locking component 63, the gear 62 is locked in place, reducing unnecessary slippage of the storage box 53 during vertical movement and improving the operational stability of the lifting assembly 5. The specific structural design and locking method of the gear 62 and locking component 63 are not limited to... Figure 2 Taking the connection method as an example, the position of the snap-fit ​​63 can be set according to the actual use requirements, and the gear 62 can be used to connect and snap-fit ​​in the corresponding rotation direction. The maintenance personnel can flexibly adjust the position of the storage box 53 by turning the snap-fit ​​63 according to the transfer requirements. The drive component 6 with this structure is convenient to operate and can meet the transfer process of maintenance tools or parts under a certain weight.

[0023] See Figure 3-4 The drive assembly 6 is configured as follows: a drive motor 64 is mounted on the ladder frame 2 via a first base 66 and a second base 67, respectively connected to one end of the connecting shaft 52 and driven to rotate; and an electrical control box 65 is configured to supply power to and control the drive motor 64. The drive assembly 6 can be configured as a drive motor 64 and an electrical control box 65 according to usage requirements, and are respectively mounted on the ladder frame 2 at corresponding positions via the first base 66 and the second base 67 and bolt connections. The motor shaft 641 of the drive motor 64 can be fitted and inserted into the pin groove 523 at the corresponding end of the connecting shaft 52 to drive the connecting shaft 52 to rotate. The corresponding wiring of the drive motor 64 can be connected to the electrical control box 65. The electrical control box 65 can be equipped with a built-in power supply or connected to an external power supply at a corresponding location in conjunction with the equipment to be repaired, so as to provide power to the electrical control box 65 and its drive motor 64. Combined with the control buttons 651 on the electrical control box 65, the drive motor 64 can be started, stopped, rotated, and its rotation speed can be controlled and adjusted. The drive component 6 with this structure can further improve the lifting stability and transmission efficiency of the lifting component 5. While saving time and effort, it can also be used to transfer larger and heavier repair tools or replacement parts up and down, meet different usage needs, and improve the flexibility and applicability of use.

[0024] The storage box 53 has multiple sets of wheels 531 rotatably mounted at both ends, and channel steel 21 for sliding of the wheels 531 is provided on the ladder frame 2 on both sides of the storage box 53. Specifically, in conjunction with... Figure 1 and Figure 5 As shown, the storage box 53 can be positioned by multiple sets of wheels 531 rotatably mounted at both ends and channel steel 21 positioned at corresponding positions on the ladder frame 2 during the up-and-down sliding process. This can further improve the positional stability of the storage box 53 during the up-and-down sliding process, effectively reducing the probability of unnecessary bumps or even damage to the maintenance tools or parts stored inside due to the large amplitude of shaking during the up-and-down movement of the storage box 53. This further improves the transmission efficiency and working stability of the lifting assembly 5 and the drive assembly 6.

[0025] The storage box 53 forms a storage cavity inside the storage box 53 through openings on both sides and two sets of doors 532 that are slidably arranged on the openings. The doors 532 can slide up and down on the openings on both sides through sliding grooves on the top of the storage box 53. At the same time, the storage box 53 at the bottom of the doors 532 has a slot 533 for locking the doors 532. This makes it easy to retrieve the repair tools or parts stored in the storage cavity. When the doors 532 are closed, the locking of the slots 533 also prevents the doors from shifting and causing the internal items to slide out or fall off, thus improving the use effect and transmission stability of the storage box 53.

[0026] Connecting plates 7 are also installed on the ladders 2 located on both sides of the maintenance platform 3. The connecting plates 7 are U-shaped, and multiple sets of second connecting plates 8 arranged at intervals can be detachably installed on the side walls of the connecting plates 7. A storage groove 780 is formed between the second connecting plates 8 and the corresponding side walls of the connecting plates 7. For details, please refer to [link / reference needed]. Figure 6 As shown, the U-shaped connecting plate 7, combined with the structure of the ladder frame 2, offers high ease of installation. The second connecting plate 8 can be detachably connected via bolts, allowing maintenance tools or spare parts to be stored in the storage slot 780. Multiple sets of second connecting plates 8 can be flexibly adjusted in spacing according to storage needs, utilizing bolts and the corresponding mounting holes 71 on their sidewalls. This facilitates storage and retrieval, reducing the risk of tools or spare parts falling or being lost. Furthermore, the connecting plates 7 can be installed and fixed in multiple sets on the ladder frames 2 on both sides of the maintenance platform 3 according to storage requirements. Additionally, the first seat 66 and the second seat 67 can be installed on the connecting plate 7 via bolts. The structural design of the connecting plate 7 further enhances connection stability and improves the protective effect of the ladder frame 2 on the maintenance platform 3 for maintenance personnel.

[0027] The storage slot 780 is formed by inserting multiple sets of spaced-apart partition plates 9 into the second connecting plate 8. The partition plates 9 can be detachably connected and their positions adjusted through multiple sets of slots 81 spaced-apart on the second connector. The insertion positions of the multiple sets of partition plates 9 in the storage slot 780 can be adjusted at different intervals according to the specifications and shapes of the maintenance tools or parts, so that they can be classified and stored in the storage slots 780 of the corresponding size formed by adjacent partition plates 9. At the same time, labels can be affixed for identification, further improving the storage flexibility and retrieval convenience of the second connecting plate 8 on the connecting plate 7.

[0028] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
