[0002] Generally speaking, during the production and rectification and improvement process of large-scale special-purpose vehicle modification companies, it involves climbing to the roof of the vehicle (the vehicle is about 3.5 meters high), or other situations that require the use of movable ladders for climbing. Based on such a higher working position, they usually use straight bamboo ladders, lifting platforms and other facilities for climbing operations.

[0003] However, the lifting platform has disadvantages such as large size, high cost, limited off-site power supply, inconvenient transportation, and limited usage scenarios. The bamboo ladder is inconvenient to go up and down, and there is nowhere to put long and small materials, tools, etc., and it is frequent to go up and down the bamboo ladder to get things, which is very inconvenient and poses a safety hazard.

[0038] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0039] Embodiment 1:

[0040] like Figure 1-Figure 7 As shown, the multifunctional climbing work ladder of this embodiment includes a main structure 1, the bottom of the main structure 1 is placed at the work point, and a rotating platform group 2 is arranged on the main structure 1;

[0041] The rotating platform group 2 includes a plurality of lower platforms 21 stacked in a vertical direction, and the same side of the plurality of lower platforms 21 are hinged to the main structure 1;

[0042] When the multiple lower platforms 21 are all in contact with the main structure 1, the climbing work ladder is in a column shape;

[0043] The multiple lower platforms 21 rotate relative to the main structure 1, and the rotation angle of each lower platform 21 increases from top to bottom. When the vertical projection areas of adjacent lower platforms 21 partially overlap, the adjacent lower platforms 21 form a step shape.

[0044] A storage structure is provided on the main structure 1 , and the storage structure includes a first storage slot 13 located at the top of the main structure 1 .

[0045] Specifically, when working on the roof, the climbing ladder is placed on the ground on one side of the vehicle, where the ground is the working point;

[0046] like Figure 3 As shown, a plurality of continuously stacked lower platforms 21 rotate in a direction away from the main structure 1 to form a continuous step for climbing from the ground below the main structure 1 to the upper height position of the main structure 1. The number of the lower platforms 21 and the rotation angle of the lowest lower platform 21 are related to the working height to be climbed;

[0047] After the multiple lower platforms 21 are rotated toward and close to the main structure 1 and fit with the main structure 1, the climbing work ladder is columnar, which makes the climbing work ladder small in size and easy to transport.

[0048] By arranging a plurality of platforms stacked in the vertical direction on the main structure 1 and rotating and changing the relative angles of the plurality of platforms, the overall appearance of the climbing work ladder can be changed. When needed, the plurality of platforms can form a continuous step, and when not needed, the plurality of platforms can be retracted, so that the climbing work ladder has a columnar appearance for easy storage. At the same time, a storage structure is arranged on the main structure 1 for placing the required materials and items during climbing work, thereby facilitating the transportation of the climbing work ladder and the taking and placing of tools and materials during climbing work.

[0049] The multifunctional climbing ladder of this embodiment has various functions and a small size, which is convenient for storage and transportation. It can meet the climbing operation requirements of large-scale special-purpose vehicles and small enterprises, and has flexible and rich usage scenarios. When not in use, it saves storage space and is also convenient for transportation to outdoor environments. In addition, each platform has a rotating climbing path after unfolding, making climbing easy.

[0050] Further, if Figure 1-Figure 7 As shown, the cross section of the lower platform 21 is semicircular. The semicircular lower platform 21 is convenient for forming a smooth climbing path.

[0051] It also includes a lower support member 41 , which is used to support the lower platform 21 .

[0052] Specifically, in order to ensure the stability of each lower platform 21, a lower support member 41 can be set on each lower platform 21. The structure of the lower support member 41 includes a first support rod, the upper end of the first support rod is fixedly connected to the outer side of the lower platform 21, and the lower end of the first support rod is provided with a universal wheel with a locking function.

[0053] You can also Figure 4 As shown, the number of the lower support member 41 is one, which is used to support the lowermost lower platform 21 , and the lower lower platform 21 among the adjacent lower platforms 21 is used to support the upper lower platform 21 .

[0054] A first universal ball bearing 211 is provided between adjacent lower platforms 21, for slidingly supporting the lower platform 21 above the lower platform 21. The mounting portion of the first universal ball bearing 211 is mounted on the bottom of the lower platform 21, and the rolling portion of the first universal ball bearing 211 is in sliding contact with the lower platform 21 below it.

[0055] The lower limit member 31 is connected to the plurality of lower platforms 21 at the same time, and is used to limit the relative positions between the lower platforms 21 .

[0056] Specifically, the lower limit member 31 may be a flexible chain, and an eyebolt is disposed on the outer side of each lower platform 21, and the flexible chain passes through the hole of each eyebolt;

[0057] When the multiple lower platforms 21 are all in contact with the main structure 1, the flexible chain is tightened and the overall length is shortened, so that the multiple lower platforms 21 completely overlap and are fixed together;

[0058] When the lower platform 21 rotates to form a step, the flexible chain stretches, and the length of the flexible chain between each eye bolt is equal. The multiple lower platforms 21 are interconnected by the flexible chain, which is used to limit the positional relationship between the multiple lower platforms 21. In order to make the lower limit member 31 more effective, the flexible chain is detachably fixed to each eye bolt. Since the positions of the main structure 1 and the lower support member 41 and the ground are relatively fixed, the relative position of each lower platform 21 is also stably restricted at this time.

[0059] Embodiment 2:

[0060] On the basis of the first embodiment, in order to ensure that the center of gravity of the entire climbing work ladder is relatively stable when in use, the rotating platform group 2 is divided into two sections, such as Figure 4 , Figure 6 As shown, the main structure 1 includes a lower body 11 located below and an upper body 12 located above the lower body 11, a lower platform 21 is installed on the lower body 11, and the axes of the hinge shafts of adjacent lower platforms 21 coincide with each other. The rotating platform group 2 also includes a plurality of upper platforms 22;

[0061] Multiple upper platforms 22 are stacked in the vertical direction, and multiple upper platforms 22 are hingedly mounted on each upper body 12, and the axes of the hinge shafts of adjacent upper platforms 22 coincide with each other;

[0062] The upper platform 22 and the lower platform 21 have the same structure, and the upper body 12 and the lower body 11 have the same structure;

[0063] The cross-sections of the upper platform 22 and the lower platform 21 are staggered at 90 degrees. The upper platform 22 and the lower platform 21 have the same rotation direction. The rotation angle of each upper platform 22 increases from bottom to top. When the vertical projection areas of adjacent upper platforms 22 partially overlap, the adjacent upper platforms 22 form a step shape.

[0064] When the multiple lower platforms 21 and the multiple upper platforms 22 are all in contact with the main structure 1 , the climbing work ladder is in a column shape.

[0065] Specifically, the main structure 1 can be an integrated structure or a split structure; the upper platform 22 and the lower platform 21 have the same structure, both are semicircular platforms, the upper main body 12 and the lower main body 11 have the same structure, both are semicircular columns, and the cross-sections of the upper platform 22 and the lower platform 21 are staggered at ninety degrees, that is, the cross-section centers of the upper platform 22 and the lower platform 21 coincide, but the straight sides of the two semicircles are staggered at ninety degrees. When multiple lower platforms 21 and multiple upper platforms 22 are all in contact with the main structure 1, the climbing work ladder is cylindrical. At this time, when the climbing work ladder moves, the universal wheels located at the bottom of the main structure 1 and the universal wheels located at the bottom of the lower support 41 and the upper support 42 are unlocked, and the climbing work ladder is pushed to move the climbing work to the target position.

[0066] The staggered upper platform 22 and lower platform 21 will disperse the step structure on both sides of the center of the main structure 1, so that the center of gravity of the entire climbing work ladder is relatively stable when in use.

[0067] Furthermore, a fixed platform 20 corresponding to the upper platform 22 is provided at the lower end of the upper body 12, and an upper support member 42 connected to the upper platform 22 is also provided. The fixed platform 20 is used to support the lowermost upper platform 22, and the lower upper platform 22 supports the upper upper platform 22. In addition, a second universal ball bearing 221 is installed at the bottom of the upper platform 22 to facilitate the relative rotation of adjacent upper platforms 22.

[0068] The structure of the upper support member 42 includes a second support rod, the upper end of the second support rod is fixedly connected to the outer side of the upper platform 22, and the lower end of the second support rod is provided with a universal wheel with a locking function.

[0069] The upper support member 42 is used to support the upper platform 22 to ensure the bearing capacity of the upper platform 22 . The upper support member 42 may be provided on each upper platform 22 , or may be provided on the lowest upper platform 22 and the highest upper platform 22 .

[0070] The upper limit positioning member 32 is connected to the plurality of upper platforms 22 at the same time, and the upper limit positioning member 32 is used to limit the relative positions between the upper platforms 22 .

[0071] Specifically, the upper limit member 32 may be a flexible chain, and an eyebolt is disposed on the outer side of each upper platform 22, and the flexible chain passes through the hole of each eyebolt;

[0072] When the multiple upper platforms 22 are all in contact with the main structure 1, the flexible chain is tightened and the overall length is shortened, so that the multiple upper platforms 22 completely overlap and are fixed together;

[0073] When the upper platform 22 rotates to form steps, the flexible chain stretches, and the length of the flexible chain between each eye bolt is equal. The multiple upper platforms 22 are interconnected by the flexible chain, which is used to limit the positional relationship between the multiple upper platforms 22. In order to make the upper limit member 32 more effective, the flexible chain is detachably fixed to each eye bolt, and the position of the main structure 1 and the upper support member 42 relative to the ground is fixed. At this time, the relative position of each upper platform 22 is also stably restricted.

[0074] The storage structure includes a first storage slot 13 located at the top of the main structure 1 , and also includes a second storage slot 14 located at the side of the lower body 11 .

[0075] Specifically, the second storage tank 14 can be located on the outer side of the lower part of the lower body 11, or on the side where the lower platform 21 and the lower body 11 are in contact, such as Figure 4 As shown, a bottom platform is provided at the bottom of the lower body 11 on this side, which can be used as a resting platform, and the second storage slot 14 can be used to place work clothes and other supplies.

[0076] In addition, the upper platform 22 and the lower platform 21 are both hollow shells, and the interior can also be used as storage space. After the upper platform 22 and the lower platform 21 are rotated to form steps, the access openings arranged on the plane side walls of the semicircular platform are exposed, and the operator can take and place items. The multifunctional aerial work ladder of this embodiment meets various storage and rest functions.

[0077] The first storage slot 13 at the top of the main structure 1 can be a plurality of slots with different depths, which is convenient for storing materials of different lengths. A foot pedal is provided on one side of the first storage slot 13. When the operator is working at the top of the climbing work ladder, he can take materials from the first storage slot 13 without carrying the materials with him, thereby improving the convenience of the operator's operation.

[0078] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
