[0023] like Figures 1 to 3As shown, a climbing device for repairing a hydropower station comprises a support rod 1, wherein the number of the support rods 1 is two, a plurality of first cross bars 2 are fixedly connected between the two support rods 1, an extension assembly 3 is arranged on the back side of the support rod 1, a positioning assembly 4 for limiting the extension assembly 3 is arranged on the top end of the support rod 1, an auxiliary moving assembly 5 is arranged on the bottom of the support rod 1, and an adjusting assembly 6 for controlling the rotation of the auxiliary moving assembly 5 is arranged on the bottom end of the support rod 1. More specifically, the user leans the support rod 1 and the extension component 3 against the surface of the equipment to be repaired, and climbing can be achieved by stepping on the first cross bar 2 and the extension component 3. The limit on the extension component 3 is released by the positioning component 4, and the extension component 3 can be pulled to adjust the overall length of the support rod 1 and the extension component 3. The extension component 3 is then limited by the positioning component 4 to fix the overall length of the support rod 1 and the extension component 3, thereby meeting the climbing requirements at different heights. When use is completed, the auxiliary moving component 5 is controlled to rotate by the adjustment component 6, so that the auxiliary moving component 5 comes into contact with the ground and the bottom end of the support rod 1 is separated from the ground. At this time, the auxiliary moving component 5 can be used to quickly move the device.

[0024] The extension component 3 includes a support frame 301, a plurality of second cross bars 302 are fixedly connected to the surface of the support frame 301, a T-shaped slider 303 is fixedly connected to the front of the support frame 301, and a limiting groove 304 is provided on the back of the support rod 1, and the inner wall of the limiting groove 304 is slidably connected to the surface of the T-shaped slider 303. It should be noted that after the support frame 301 is released from the limit by the positioning component 4, the support frame 301 is pulled to drive the T-shaped slider 303 to slide along the inner wall of the limiting groove 304, so that the total length of the support frame 301 and the support rod 1 changes. When the length is adjusted to a suitable length, the positioning component 4 is used again to limit the support frame 301, thereby changing the overall length of the device to adapt to climbing at different heights. The user can climb up by stepping on the second cross bar 302.

[0025] The positioning assembly 4 includes a first mounting groove 401, and the first mounting groove 401 is opened at the end of the support rod 1, the inner wall of the first mounting groove 401 is movably connected with the insertion rod 402, a plurality of positioning holes 405 are opened on the front side of the support frame 301, and the inner wall of the positioning hole 405 is movably connected with the end of the insertion rod 402, a spring 404 is fixedly connected to the front side of the inner wall of the first mounting groove 401, and the free end of the spring 404 is fixedly connected to the insertion rod 402, and the front end of the insertion rod 402 is fixedly connected with a pull ring 403. More specifically, by pulling the pull ring 403, the insertion rod 402 is driven to move forward and the spring 404 is compressed at the same time, so that the end of the insertion rod 402 is separated from the inner wall of the positioning hole 405, and the limit on the support frame 301 can be released. When the support frame 301 is adjusted to a desired position, the pull ring 403 is released, and the elastic force of the spring 404 drives the insertion rod 402 to move backward, so that the insertion rod 402 is reinserted into the inner wall of the positioning hole 405, and the support frame 301 can be limited again.

[0026] The auxiliary moving assembly 5 includes a fixed seat 501, and the fixed seat 501 is fixedly connected to the support rod 1. The surface of the fixed seat 501 is rotatably connected to a mounting plate 502, and the surface of the mounting plate 502 is provided with a roller 503. It should be noted that the mounting plate 502 is driven to rotate around the fixed seat 501 by the adjustment assembly 6, so that the roller 503 also rotates, and finally the roller 503 contacts the ground, and the device can be moved by the roller 503.

[0027] The adjustment assembly 6 includes a second mounting groove 601, and the second mounting groove 601 is opened on the surface of the support rod 1, the inner wall of the second mounting groove 601 is rotatably connected with a screw rod 602, the surface of the screw rod 602 is fixedly sleeved with a turntable 603, the surface of the screw rod 602 is threadedly connected with a threaded sleeve 605, the side of the threaded sleeve 605 is rotatably connected with a connecting rod 604, and the end of the connecting rod 604 is rotatably connected with the mounting plate 502. More specifically, by rotating the turntable 603, the screw rod 602 is driven to rotate, and under the action of the thread, the threaded sleeve 605 will be driven to slide along the inner wall of the second mounting groove 601, thereby pulling the connecting rod 604 to rotate, and the bottom end of the connecting rod 604 will push the mounting plate 502 to rotate.

[0028] The bottom end of the support rod 1 is fixedly connected with an anti-skid pad 7, and the anti-skid pad 7 is made of rubber. It should be noted that by providing the anti-skid pad 7 made of rubber material, the friction between the device and the ground is increased, so that when the device is used in a tilted position, it is not easy to slide relative to the ground.

[0029] In summary: the user places the support rod 1 and the extension component 3 on the surface of the equipment to be repaired, and climbing can be achieved by stepping on the first cross bar 2 and the extension component 3. The extension component 3 can be pulled to adjust the overall length of the support rod 1 and the extension component 3 through the positioning component 4. The extension component 3 is then limited by the positioning component 4 to fix the overall length of the support rod 1 and the extension component 3, thereby meeting the climbing requirements at different heights. After use, the auxiliary moving component 5 is controlled to rotate through the adjustment component 6, so that the auxiliary moving component 5 comes into contact with the ground and the bottom end of the support rod 1 is separated from the ground. At this time, the auxiliary moving component 5 can be used to quickly move the device, which achieves the effect of facilitating the rapid movement of the climbing device during use. There is no need for manpower to carry the device under load, which makes the carrying process easier and more labor-saving, and also makes the maintenance work of the hydropower station more convenient. It can also meet the climbing requirements at different heights and is more flexible to use.
