DETAILED DESCRIPTION

[0028] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0029] In this disclosure, unless otherwise stated, directional words such as "up" and "down" are defined according to the direction of the maintenance ladder. Figure 3 and Figure 4 The directions of the drawings, "inside" and "outside" are defined according to the outlines of the corresponding parts. The terms used in this disclosure, such as "first" and "second", are used to distinguish one element from another and do not have order and importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0030] See also Figure 1 , Figure 2 and Figure 5 , a maintenance ladder provided in an embodiment of the present disclosure includes a ladder frame, a tool box 300 and a receiving tray 400. Among them, a hanging rod 110 can be installed on the top of the ladder frame, and the tool box 300 can be installed on the hanging rod 110. The ladder frame may include a first ladder frame 100 and a second ladder frame 200. Among them, the second ladder frame 200 is rotatably connected to the first ladder frame 100, for example, the top of the second ladder frame 200 can be rotatably connected to the top or middle of the first ladder frame 100, and the specific installation positions of the two are prior art and will not be repeated here. The hanging rod 110 can be set at the top of the first ladder frame 100 or the second ladder frame 200.

[0031] In this embodiment, the receiving tray 400 is rotatably arranged in the tool box 300. For example, the receiving tray 400 can be installed with the tool box 300 through the rotating shaft 510 and the slider 520 mentioned in the subsequent embodiments; or the receiving tray 400 can be directly placed on the bottom wall of the tool box 300. A partition plate 410 can be installed in the receiving tray 400. The partition plate 410 can be used to divide the space in the receiving tray 400 into a plurality of receiving cavities 420. The plurality of receiving cavities 420 can be separated and arranged along the circumference of the receiving tray 400. The receiving cavities 420 can be used to accommodate maintenance tools (not shown in the figure). The top of the tool box 300 can be provided with an opening 310. The receiving tray 400 can be configured to be able to rotate so that one of the plurality of receiving cavities 420 is connected to the opening 310.

[0032] It is understandable that the maintenance personnel can classify the maintenance tools and put them into the designated accommodating chamber 420. The top of the tool box 300 is provided with an opening 310. When the maintenance personnel need to take a certain tool, the accommodating plate 400 is driven to rotate relative to the tool box 300 so that the accommodating chamber 420 containing the tool is connected with the opening 310, and the maintenance personnel take out the required maintenance tools through the opening 310. The maintenance ladder in the embodiment of the present disclosure can effectively save the maintenance personnel's time in searching for tools, ensure that the maintenance personnel can quickly take out the required tools, and improve the safety of the maintenance personnel working at heights.

[0033] The maintenance tools are classified and placed in the accommodating cavity 420, which saves the maintenance workers' time in searching for tools and ensures that the maintenance workers can quickly take out the required tools.

[0034] In one embodiment, see Figure 2 and Figure 5The accommodating tray 400 may be provided with a blocking portion 430, which may be disposed between two adjacent accommodating cavities 420. The blocking portion 430 may be configured to block the opening 310 when rotated to correspond to the opening 310, so that the tool box 300 is presented in a closed state when not in use, so as to prevent the maintenance tools in the accommodating cavity 420 from falling out of the tool box 300 and to protect the tools from rusting or being damaged due to contact with air.

[0035] Furthermore, the number of the blocking parts 430 may be one, two, or more than three, which is not specifically limited herein, and the blocking part 430 may be a solid structure or a hollow structure.

[0036] In one embodiment, see Figure 2 and Figure 5 The maintenance ladder may further include a driving mechanism 500, which may be installed between the accommodating tray 400 and the toolbox 300. The driving mechanism 500 may be configured to: drive the accommodating tray 400 to rotate, so that the maintenance worker does not need to put his hand into the accommodating cavity 420 to push the accommodating tray 400 to rotate, thereby facilitating the taking of maintenance tools. When the driving mechanism 500 drives the blocking portion 430 to face the opening 310, the driving mechanism 500 can limit the rotation of the accommodating tray 400, thereby ensuring that the blocking portion 430 can still block the opening 310 in the event of shaking or falling, thereby preventing the maintenance tools from falling out of the toolbox 300.

[0037] For further information, see Figure 2 and Figure 4 , a sliding cavity 440 may be provided in the receiving tray 400, and the cross section of the sliding cavity 440 may be configured as a rectangle or a circle, etc., and a plurality of receiving cavities 420 may be located in the circumference of the sliding cavity 440, and the driving mechanism 500 may include a rotating shaft 510 and a slider 520. The rotating shaft 510 may be rotatably extended into the sliding cavity 440. The slider 520 may be installed at the bottom of the rotating shaft 510, and the slider 520 may be configured to be slidably arranged in the sliding cavity 440 along the axial direction of the rotating shaft 510, and may be locked with the circumference of the sliding cavity 440 in the circumferential direction, so as to ensure that the slider 520 can drive the receiving tray 400 to rotate synchronously through the sliding cavity 440, wherein the driving mechanism 500 may have a release position and a locking position, in which the rotating shaft 510 can rotate in the release position to drive the receiving tray 400 to rotate through the slider 520, and in the locking position, the rotating shaft 510 may be engaged with the tool box 300 to limit the rotation of the receiving tray 400.

[0038] It can be understood that when the driving mechanism 500 is in the release position, the maintenance worker can take and place specific tools. Specifically, the maintenance worker drives the rotating shaft 510 to drive the slider 520 to move along the axial direction of the rotating shaft 510, and drives the rotating shaft 510 to rotate, so that the slider 520 can promote the circumferential rotation of the sliding cavity 440, thereby rotating the accommodating disk 400, and when the specific accommodating cavity 420 is connected to the opening 310, the maintenance worker can put in or take out the designated tool; after taking and placing the tool, the maintenance worker drives the rotating shaft 510 to rotate, and when the blocking portion 430 corresponds to the opening 310, the rotating shaft 510 and the tool box 300 are engaged to prevent the accommodating disk 400 from rotating, thereby preventing the tool from falling out of the tool box 300.

[0039] In this embodiment, there are two ways for the slider 520 to achieve circumferential locking with the sliding cavity 440 in the circumferential direction. For example, the side wall of the sliding cavity 440 is provided with a groove extending up and down, and the slider 520 is provided with a protrusion, which is slidably set in the groove. The slider 520 can drive the protrusion to slide up and down relative to the groove. The slider 520 can also drive the protrusion to rotate so that the protrusion abuts against the groove wall of the groove, so that the sliding cavity 440 rotates synchronously with the slider 520; or, the sliding cavity 440 and the slider 520 are in contact cooperation, and the rotating shaft 510 drives the slider 520 to move up and down to overcome the friction between the slider 520 and the sliding cavity 440. The rotating shaft 510 can also drive the slider 520 to rely on the friction between the slider 520 and the sliding cavity 440 to drive the accommodating disk 400 to rotate synchronously.

[0040] In one embodiment, see Figure 3 and Figure 4 , the inner wall of the top of the toolbox 300 may be provided with a first engaging portion 321, and the outer periphery of the rotating shaft 510 may be provided with a second engaging portion 511. In the locking position, the first engaging portion 321 may be engaged with the second engaging portion 511 to prevent the rotating shaft 510 from driving the slider 520 to drive the accommodating plate 400 to rotate. For example, the first engaging portion 321 may be a tooth hole, and the second engaging portion 511 may be a gear, and the rotation of the rotating shaft 510 is limited by the engagement between the gear and the tooth hole. Of course, in other embodiments, the first engaging portion 321 is a male connector, and the second engaging portion 511 is a female connector.

[0041] Furthermore, the second engaging portion 511 may be disposed on the outer periphery of the top of the rotating shaft 510 to prevent the rotating shaft 510 from extending too long out of the sliding cavity 440 , thereby reducing the processing cost of the rotating shaft 510 .

[0042] Understandably, see Figure 4When the maintenance worker needs to take or place a specific tool, the driving shaft 510 drives the slider 520 to move upward to release the restriction of the first engaging portion 321 on the second engaging portion 511. Then, the maintenance worker drives the shaft 510 to drive the slider 520 to push the receiving plate 400 to rotate, so that the receiving cavity 420 containing the specific tool is connected to the opening 310; please refer to Figure 3 After the placement is completed, the maintenance worker drives the shaft 510 to rotate. When the blocking portion 430 corresponds to the opening 310, the shaft 510 drives the slider 520 to move downward, so that the first engaging portion 321 engages with the second engaging portion 511 to prevent the accommodating tray 400 from rotating.

[0043] In one embodiment, see Figure 3 and Figure 4 The drive mechanism 500 may further include a spring 530, which may be elastically disposed between the sliding cavity 440 and the slider 520, and may be sleeved on the outer periphery of the rotating shaft 510. For example, the spring 530 may be connected between the slider 520 and the sliding cavity 440 to ensure that the slider 520 may move smoothly under the elastic force of the spring 530; or, the spring 530 may be placed between the sliding cavity 440 and the slider 520 to facilitate the replacement of the spring 530. The spring 530 may be configured as follows: when the drive mechanism 500 is in the locked position, the spring 530 may be in the initial state, and when the drive mechanism 500 is in the released position, the spring 530 may be in the changed state. In the initial state, the drive mechanism 500 does not require external force intervention by a maintenance worker, but in the changed state, external force intervention is required.

[0044] It can be understood that when a maintenance worker needs to take or place a specific tool, he first pulls the shaft 510 upward to change the spring 530 (stretch or compress), and then drives the shaft 510 to rotate so that the specific accommodating cavity 420 is opposite to the opening 310. After taking or placing, the shaft 510 is rotated to make the blocking portion 430 face the opening 310, and then the shaft 510 is released. The slider 520 and the shaft 510 can automatically move downward under the combined action of their own gravity and the restoring force of the spring 530. There is no need for the maintenance worker to manually reset the shaft 510. The shaft 510 can be engaged with the toolbox 300 during the descent to limit the continued rotation of the accommodating tray 400.

[0045] In one embodiment, see Figure 3 and Figure 4The spring 530 can be arranged between the top wall of the sliding cavity 440 and the top surface of the slider 520, so that when the rotating shaft 510 is lifted upward, the spring 530 is compressed to put the driving mechanism 500 in the release position. After the hand is released, the rotating shaft 510 automatically moves downward under the combined action of the gravity of the structures connected thereto and the restoring force of the spring 530, so that the rotating shaft 510 can be automatically engaged with the tool box 300. By arranging the spring 530 on the top surface of the slider 520, it is convenient to replace the spring 530.

[0046] In this implementation, see Figure 3 A handle 512 is installed on the top of the rotating shaft 510 to facilitate the maintenance worker to drive the rotating shaft 510 to move.

[0047] In one embodiment, see Figure 2 The toolbox 300 may include a mounting portion 330, which is rotatably mounted on the hanging rod 110. Under the action of its own gravity, the toolbox 300 will remain vertical relative to the ground, avoiding the toolbox 300 from tilting due to a change in the angle between the first ladder frame 100 and the ground, thereby preventing the maintenance tools from falling out.

[0048] For further information, see Figure 2 The outer periphery of the hanging rod 110 may be sleeved with two spaced apart limiting rings 610, which may be used to abut the mounting portion 330 to limit the movement of the toolbox 300 along the axial direction of the hanging rod 110, thereby ensuring the stability of the toolbox 300 when taking and placing tools.

[0049] In one embodiment, see Figure 1 A lap platform 710 may be installed between the first ladder frame 100 and the second ladder frame 200. One end of the lap platform 710 is rotatably connected to the first ladder frame 100, and the other end may be lapped on the second ladder frame 200. The lap platform 710 may be stepped on by a user.
