[0028] In order to enable those skilled in the art to better understand the technical solution of the utility model, the solution will be further described in detail below in conjunction with specific embodiments.

[0029] like Figures 1 to 4 As shown, the embodiment of the utility model provides a maintenance climbing ladder, which includes a supporting mechanism and two supporting mechanisms. The supporting mechanism includes a supporting plate 401 and two adjusting plates 404. The adjusting plates 404 are L-shaped structures. The left and right sides of the supporting plate 401 are provided with sliding grooves for slidingly cooperating with the horizontal plate 4041 of the adjusting plate; the front and rear sides of the horizontal plate 4041 are provided with fixing columns 403, and the front and rear sides of the supporting plate are provided with elongated sliding holes 406 for slidingly cooperating with the fixing columns, and the elongated sliding holes are connected to the sliding grooves; the fixing column 403 is threadedly connected with a fastening nut 405 at one end away from the horizontal plate; the two The supporting mechanism is respectively connected to the front and rear sides of the lower side of the supporting plate 401, and the supporting mechanism includes a base 101, an installation shaft 201, a climbing column 306 and two supporting columns. Two receiving grooves 102 are relatively arranged on the base 101, and the installation shaft 201 passes through the lower ends of the two supporting columns, the two receiving grooves 102 and the base 101; the lower ends of the two supporting columns are rotatably arranged in the two receiving grooves through the installation shaft 201, and the upper ends of the two supporting columns are rotatably connected to the lower side of the supporting plate 401; a plurality of climbing columns 306 are sequentially arranged between the two supporting columns from top to bottom, and the two ends of the climbing column are respectively vertically connected to the two supporting columns.

[0030] The maintenance ladder provided by the embodiment of the utility model, when in use, has the lower end of the support column rotatably set in the accommodating groove 102, and the upper end of the support column is rotatably connected to the lower side surface of the support plate. By making the two support mechanisms move away from each other, the two support mechanisms, the support plate 401 and the ground can form an isosceles trapezoidal structure together, thereby achieving stable support for the support plate, making it safer for maintenance personnel to perform maintenance operations on the support plate. At the same time, by pulling the horizontal plate of the adjustment plate 404 to slide in the slide groove of the supporting plate, the horizontal plate 4041 can be pulled out of the slide groove, so that not only the top surface of the supporting plate can be used for load-bearing, but also the top surface of the pulled-out horizontal plate 4041 can be used for load-bearing, so that the maintenance ladder can better adapt to different maintenance needs, such as temporarily placing disassembled parts or tools on the top surface of the horizontal plate, or meeting the comfort of different maintenance personnel when sitting on the supporting plate to perform maintenance work; and the vertical plates 4042 of the two adjustment plates can play a better blocking role, such as blocking parts or tools placed on the horizontal plate or the supporting plate, and blocking the front and rear sides of the maintenance personnel, thereby effectively improving the safety of the maintenance ladder when in use.

[0031] Further, the support column includes a first support block 301 and a second support block 303, the lower end of the first support block 301 is provided with a through hole for the installation shaft to pass through, the upper end of the first support block is provided with a mounting groove for the lower end of the second support block to penetrate; the upper end of the second support block 303 is rotatably connected to the lower side of the support plate, the lower end of the second support block 303 is provided with a first through hole 307 for the fixing bolt 302 to pass through, the left and right sides of the installation groove are provided with second through holes opposite to the first through holes, and the fixing bolt passes through the first through hole and the second through hole and then matches with the fixing nut 304. With this solution, the threaded section of the fixing bolt passes through the second through hole on the left side of the installation groove, the first through hole on the second support block, and the second through hole on the right side of the installation groove, and then matches with and is tightened with the fixing nut, so that the detachable connection between the first support block and the second support block can be easily realized, so that they can be replaced or repaired separately.

[0032] It is understandable that a climbing column is provided between the two first support blocks 301 of the support mechanism, and a climbing column 306 is also provided between the upper ends of the two second support blocks 303. It is preferred that the climbing columns are evenly distributed from top to bottom. Since the lower end of the first support block is rotatably provided in the receiving groove through the installation axis, the lower end of the first support block has a certain rotation space in the receiving groove. When the lower end of the first support block rotates to be in contact with the front inner wall or the rear inner wall of the receiving groove, the first support block will no longer rotate around the installation axis. In order to allow the lower end of the first support block to have a certain rotation space in the receiving groove, the size of the receiving groove is larger than the size of the lower end of the first support block. The difference between the two sizes can be flexibly set as needed, which will not be repeated here. In the two support mechanisms, the two support columns of one of the support mechanisms are rotatably connected to the front side of the lower side of the support plate, and the two support columns of the other support mechanism are rotatably connected to the rear side of the lower side of the support plate. When the maintenance ladder is not in use, that is, in the state of storage, it is as shown in FIG. Figure 1 As shown, at this time, the two supporting mechanisms are not moved away from each other but are folded together.

[0033] Specifically, the number of the first through holes 307 is multiple, and each of the first through holes is evenly distributed from top to bottom at the lower end of the second support block 303. With this solution, by moving the lower end of the second support block up and down in the installation slot, so that different first through holes are opposite to the second through holes, and then fastening with fixing bolts and fixing nuts, the use length of the support column, that is, the length in the vertical direction, can be adjusted, so that the height of the support plate can be adjusted, and thus the use requirements of different heights can be better met. It is understandable that when the use length of the support column increases significantly, a climbing column can be used to connect the two second support blocks extending from the two receiving slots, so as to facilitate maintenance personnel to climb up and use.

[0034] In one embodiment, the front and rear sides of the mounting groove are both provided with openings, and the left and right sides of the mounting groove are both provided with at least two second through holes. With this solution, the installation between the second support block and the first support block is more convenient and quick; at the same time, the connection between the first support block and the second support block is performed by two fixing bolts, which can make the connection between the two more firm and reliable. It can be preferred that the upper part of the left and right sides of the mounting groove are both provided with two second through holes distributed along the extension direction thereof. It can be understood that when there are no openings on the front and rear sides of the mounting groove, since the front and rear sides of the mounting groove can limit the lower end of the second support block 303, it can be preferred that the upper part of the left and right sides of the mounting groove are both provided with a second through hole, so that the front and rear sides of the mounting groove can be used to prevent the second support block from rotating around the fixing bolt, and the first support block can be firmly connected to the second support block by the cooperation of a fixing bolt and a fixing nut.

[0035] Furthermore, four mounting parts are provided on the lower side of the support plate 401, and the four mounting parts are arranged in pairs on the front and rear sides of the lower side of the support plate. The four mounting parts are rotatably connected to the upper ends of the four second support blocks in a one-to-one correspondence, thereby conveniently realizing the rotatable connection between the support plate and the four second support blocks by using the four mounting parts.

[0036] Specifically, the two second support blocks located on the same side of the support plate are rotatably connected to the two mounting members through the same connecting shaft 305; the mounting member includes two fixed plates 402 arranged opposite to each other, the space between the two fixed plates 402 is used to accommodate the upper end of the second support block 303, the upper end of the second support block is provided with a first through hole for the connecting shaft to pass through, the fixed plate is provided with a second through hole 407 for the connecting shaft to pass through, and the second through hole is opposite to the first through hole. With this solution, the rotatable connection between the support mechanism and the support plate can be conveniently achieved.

[0037] Preferably, both ends of the connecting shaft 305 are provided with limit stops, so as to better prevent the connecting shaft from coming out of the first through hole or the second through hole.

[0038] Specifically, both ends of the installation shaft 201 are threadedly connected with locking nuts 202, so that the installation shaft 201 can be better prevented from coming out of the base 101. It can be understood that the through hole at the lower end of the first support block is rotatably matched with the installation shaft; when in use, after the horizontal plate is adjusted into place, the fastening nut on the fixing column is tightened to fix the adjustment plate on the support plate, so that the horizontal plate cannot slide in the slide groove; the extension direction of the long strip slide hole is the same as the extension direction of the support plate, that is, they all extend in the left and right direction; the through hole on the first support block, the above-mentioned through holes and the axis of the perforation are all parallel to the extension direction of the support plate; the base is a long strip seat with the same extension direction as the support plate, and the two receiving grooves on the base are relatively arranged in its extension direction; the support column is arranged vertically; the vertical plate 4042 of the adjustment plate extends vertically upward.

[0039] The utility model enables maintenance personnel to sit on the support plate for a long time to perform maintenance work through the cooperation of the support plate and the adjustment plate, which can effectively prevent maintenance personnel from accidentally falling due to standing on the stepladder for a long time to perform maintenance work, and can also better meet different usage requirements during maintenance.

[0040] The above are only preferred implementation modes of the present invention. It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in the field can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
