[0027] In the specific embodiment provided by the present disclosure, a ladder for repairing water conservancy equipment is provided, referring to Figures 1 to 4As shown, the ladder for repairing water conservancy equipment includes: a ladder body 1 and a climbing mechanism 2, wherein the ladder body 1 includes two supporting rods 101 arranged opposite to each other and a cross bar 102 arranged between the two supporting rods 101, the number of the cross bars 102 is multiple, and the multiple cross bars 102 are spaced apart along the length direction of the supporting rods 101; the climbing mechanism 2 includes a climbing block 201 and a driving assembly 202, and the driving assembly 202 includes a fixed elliptical column 2021, a connecting column 2022 and a driving member 202 3. A cavity 1021 is defined within the crossbar 102 for accommodating the climbing block 201 and the elliptical cylinder 2021. An opening 1011 is defined on the support bar 101, communicating with the cavity 1021. A connecting post 2022 extends through the opening 1011 to the exterior of the support bar 101. A driving member 2023 is fixedly connected to the end of the connecting post 2022 facing away from the elliptical cylinder 2021. A through slot 1022 is further defined on the crossbar 102 for allowing a portion of the climbing block 201 to extend from the cavity 1021. The through slot 1022 communicates with the cavity 1021.

[0028] According to the above technical solution, a climbing mechanism 2 is provided on the crossbar 102. When maintenance work is required, the maintenance personnel can rotate the driving member 2023 located outside the support rod 101, and then drive the elliptical cylinder 2021 located in the cavity 1021 of the crossbar 102 to rotate synchronously through the connecting column 2022, so that the elliptical cylinder 2021 can abut the climbing block 201 and drive the climbing block 201 to extend out of the cavity 1021 through the through slot 1022 connected to the cavity 1021, that is, referring to Figure 3 As shown, at this time, the elliptical cylinder 2021 located in the cavity 1021 is in a state of abutting the elliptical cylinder 2021. Later, when the maintenance personnel step on the cross bar 102 to climb, part of the climbing block 201 extends from the cavity 1021 of the cross bar 102, so that the climbing block 201 can increase the area stepped by the maintenance personnel, increase the friction between the maintenance personnel and the cross bar 102, provide a better support point for the maintenance personnel, make the climbing process more stable, reduce the risk of the maintenance personnel slipping during the climbing process, and at the same time make the weight distribution of the maintenance personnel more even, reduce local pressure, and improve the comfort and safety of climbing.

[0029] In some embodiments, the climbing block 201 can extend out of the cavity 1021 or retract into the cavity 1021 according to actual needs. Therefore, when there is no need to perform climbing operations, maintenance personnel can rotate the driving member 2023 located outside the support rod 101, and then drive the elliptical cylinder 2021 located in the cavity 1021 of the cross bar 102 to rotate synchronously through the connecting column 2022, so that the elliptical cylinder 2021 no longer abuts the climbing block 201, and the climbing block 201 can be retracted into the cavity 1021 to maintain the flatness of the cross bar 102.

[0030] In some embodiments, reference Figure 3 As shown, in order to ensure that the maintenance personnel can be more stable when climbing, two climbing blocks 201 are provided in each cross bar 102. The two climbing blocks 201 are arranged opposite to each other along the width direction of the cross bar 102 and the elliptical cylinder 2021 is arranged between the two climbing blocks 201. That is, when the elliptical cylinder 2021 is raised, the climbing blocks 201 located on both sides of the elliptical cylinder 2021 synchronously abut the elliptical cylinder 2021, so that the two climbing blocks 201 are synchronously partially extended out of the cavity 1021 of the cross bar 102. There are two climbing blocks 201 on each cross bar 102, which can further increase the area for maintenance personnel to step on and reduce the occurrence of maintenance personnel stepping on air or slipping when climbing.

[0031] In some embodiments, during the climbing process of the maintenance personnel, the climbing block 201 should be able to always and stably partially extend out of the cross bar 102, ensuring that the climbing block 201 can provide stable support for the maintenance personnel. Based on this, the driving member 2023 includes a limit plate, which is fixedly connected to the end of the connecting column 2022 away from the elliptical cylinder 2021. The edge contour of the limit plate is rectangular, and the opening 1011 provided on the support rod 101 should have an outer contour corresponding to the edge contour of the limit plate. When the climbing block 201 partially extends out of the cavity 1021, the limit plate is embedded in the opening 1011. At this time, the limit plate can effectively limit the connecting column 2022 and the elliptical cylinder 2021 to prevent the connecting column 2022 and the elliptical cylinder 2021 from rotating, so that the climbing block 201 can provide stable support for the maintenance personnel, thereby reducing the probability of the maintenance personnel stepping on air or slipping when climbing, and improving the safety of the maintenance personnel.

[0032] In some embodiments, when the maintenance personnel no longer use the ladder, the climbing block 201 needs to be retracted into the cavity 1021. At this time, in order to enable the climbing block 201 to be able to smoothly retract into the cavity 1021, a spring 203 can be provided on the climbing block 201, that is, an extension plate 2011 for connecting the spring 203 is fixedly connected to the climbing block 201, and one end of the spring 203 facing away from the extension plate 2011 is connected to the inner wall surface of the cavity 1021. When the maintenance personnel rotates the limit plate and then drives the elliptical cylinder 2021 to rotate through the connecting column 2022, as the elliptical cylinder 2021 rotates and under the action of the elastic force of the spring 203, the protruding part of the climbing block 201 gradually retracts into the cavity 1021 of the cross bar 102.

[0033] When the maintenance work needs to be carried out, the maintenance personnel can rotate the limiting plate, and then the connecting column 2022 drives the elliptical column 2021 to rotate synchronously. With the continuous rotation of the elliptical column 2021, the elliptical column 2021 begins to abut against the climbing block 201 and the spring 203 is compressed. With the continuous compression of the spring 203, the side of the climbing block 201 away from the extension plate 2011 gradually extends out of the cavity 1021 through the through slot 1022. When the limiting plate stops rotating, the climbing block 201 stops moving. Then the limiting plate is embedded into the opening 1011, and the elliptical column 2021 is limited by the opening 1011 and the limiting plate to prevent the climbing block 201 from retracting into the cavity 1021 during the climbing process of the maintenance personnel, thereby providing stable support for the maintenance personnel and improving the safety of the maintenance personnel.

[0034] In some embodiments, with reference to Figure 3 As shown, in order to make the climbing block 201 retract into the cavity 1021 of the horizontal rod 102 more smoothly and smoothly, each climbing block 201 is provided with an extension plate 2011 at both ends arranged in the height direction of the climbing block 201, and the extension plate 2011 is connected with a spring 203. In order to ensure that the spring 203 has sufficient elastic force to make the climbing block 201 retract into the cavity 1021 of the horizontal rod 102 smoothly and smoothly, a plurality of springs 203 can be arranged along the length direction of the climbing block 201, wherein the plurality of springs 203 are arranged at equal intervals to ensure that the elastic force provided by the plurality of springs 203 can act on the climbing block 201 uniformly.

[0035] In some embodiments not shown, in order to make the elliptical column 2021 stably placed in the cavity 1021, a circular ring can be fixedly connected in the cavity 1021. The number of the circular ring is two, and the two circular rings are respectively located at both ends of the elliptical column 2021 along its own length. Meanwhile, a connecting column 2022 is fixedly connected at both ends of the elliptical column 2021 along its own length, so that the two connecting columns 2022 located at both ends of the elliptical column 2021 are respectively arranged. One of the connecting columns 2022 extends out of the cavity 1021 through the opening 1011 and is connected with the limiting plate. When the maintenance work is finished, the climbing block 201 needs to be retracted into the cavity 1021. At this time, in order to facilitate the personnel to separate the limiting plate embedded in the opening 1011 from the opening 1011, a pull ring can be fixedly connected on the side of the limiting plate away from the connecting column 2022. By pulling the pull ring, the limiting plate is separated from the opening 1011.

[0036] In order to facilitate understanding of the technical solution of the elliptical cylinder 2021 abutting the climbing block 201 in the present disclosure, the structure of the elliptical cylinder 2021 is explained, that is, the elliptical cylinder 2021 is located between the two climbing blocks 201, and the cross-section of the elliptical cylinder 2021 is an ellipse, and the ellipse has a major axis and a minor axis. Among them, when the elliptical cylinder 2021 abuts the climbing block 201, so that the climbing block 201 partially extends out of the cavity 1021 through the through groove 1022, at this time, taking the cross-section of the elliptical cylinder 2021 as an example for explanation, the major axis of the ellipse is perpendicular to the side wall surface of the climbing block 201; when the climbing block 201 is retracted into the cavity 1021, the minor axis of the ellipse is perpendicular to the side wall surface of the climbing block 201, or when the climbing block 201 is retracted into the cavity 1021, the major axis of the ellipse is parallel to the side wall surface of the climbing block 201.

[0037] In some embodiments, reference Figure 1 、 Figure 3 and Figure 4 As shown, anti-skid grooves 3 are provided on the outer wall of the climbing block 201, wherein the anti-skid grooves 3 can increase the friction between the climbing block 201 and the soles of the maintenance personnel's shoes, thereby preventing safety accidents caused by slipping during the climbing process, and providing good support for the maintenance personnel even in a slippery working environment, thereby significantly reducing the risk of accidents for the maintenance personnel during the climbing process; at the same time, the anti-skid grooves 3 on the climbing block 201 are usually made of wear-resistant materials, which can withstand long-term use without being easily worn, thereby ensuring the service life of the climbing block 201.

[0038] In some embodiments, reference Figure 4 As shown, in order to enable the ladder to be stably leaned against the wall when in use, a suction cup 4 can be provided on the support, wherein both support rods 101 are provided with a suction cup 4. At the same time, the suction cup 4 can be movably connected to the support rod 101, thereby ensuring that the suction cup 4 can rotate at multiple angles, so that the suction cup 4 can better adsorb on the outer wall surface of the wall, that is, a universal ball head is connected to one end of the suction cup 4, and a chamber for accommodating the universal ball head is provided on the support rod 101. The chamber has a channel connected to the outside world, and part of the universal ball head extends out of the chamber through the channel and the part of the universal ball head located in the external environment is connected to the suction cup 4.

[0039] In some embodiments, reference Figure 1 and Figure 2When the ladder is leaning against a column such as a telephone pole, in order to ensure that the ladder can be leaned against stably, the fixing assembly 5 can be used to improve the stability of the ladder when leaning against the column. The fixing assembly 5 includes a rotating rod 501, a rope 502 and a toggle member 503. The support rod 101 is provided with a storage channel for storing the rotating rod 501 and the rope 502. The rope 502 is wound around the rotating rod 501. One end of the rotating rod 501 is rotatably connected to the support rod 101, and the other end passes through the support rod 101 and extends to the outside of the support rod 101. The toggle member 503 is fixedly connected to the end of the rotating rod 501 away from the support rod 101. That is, when leaning against the column, the maintenance personnel can rotate the toggle member 503 to drive the rotating rod 501 to rotate synchronously. As the rotating rod 501 continues to rotate, the rope 502 wrapped around the rotating rod 501 is released, and the rope 502 can be tied to the column being leaned against, thereby improving the stability of the ladder when leaning against.

[0040] In some embodiments, reference Figure 2 As shown, in order to facilitate maintenance personnel to rotate the toggle member 503, a socket 5031 can be provided on the end of the toggle member 503 away from the rotating rod 501, that is, when the toggle member 503 needs to be rotated, the maintenance personnel can insert their fingers into the socket 5031 and rotate it, or use a tool such as a metal rod to insert it into the socket 5031 and rotate it.

[0041] In some embodiments, reference Figure 1 and Figure 2 As shown, in order to further improve the firmness of the binding of the rope 502, thereby improving the stability of the ladder when leaning against the column, a binding column 6 can be provided on the support rod 101 on the side away from the fixed component 5, and the number of the binding columns 6 is multiple. The rope 502 can be wrapped around the leaning column and then wrapped around the binding column 6, thereby improving the stability of the ladder when leaning.
