[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-13 The present invention provides a technical solution: a steel column climbing ladder, including a climbing ladder body 1, hooks 2 disposed on the top of the climbing ladder body 1, and support frames 3 spaced apart on the sides of the climbing ladder body 1, and further including: a fixing unit 4 disposed between a first ladder plate 11 and a second ladder plate 12, for assembling and fixing the first ladder plate 11 and the second ladder plate 12; the fixing unit 4 includes: a top-feeding plate 41 disposed on the side where the first ladder plate 11 and the second ladder plate 12 are connected; a pushing mechanism 42 adjustablely disposed inside the second ladder plate 12; and a fixing mechanism 44 disposed inside the second ladder plate 12 and connected to the pushing mechanism 42 through a turning mechanism 43, for fixing the top-feeding plate 41 after it is inserted into a set position inside the second ladder plate 12.

[0021] It should be noted that during operation, the distance between each segment of the first ladder plate 11 and the second ladder plate 12 is 3 meters. The first ladder plate 11, along with one side of the top-feeding plate 41, is inserted into the interior of the second ladder plate 12. During insertion, the pushing mechanism 42, through the turning mechanism 43, drives the fixing mechanism 44 to move towards one side of the interior of the second ladder plate 12, providing space for the top step 14 to move. When the top of the first ladder plate 11 contacts the bottom of the second ladder plate 12, the top-feeding plate 41 is installed in its designated position inside the second ladder plate 12. At this point, the fixing mechanism 44 is pushed, causing it to engage with the top-feeding plate 41, thus fixing the top-feeding plate 41 inside the second ladder plate 12, completing the assembly of the first ladder plate 11 and the second ladder plate 12. After assembly, the sealing plug 13 is fixed to the top of the first ladder plate 11 and the bottom of the second ladder plate 12. The first ladder plate 11 and the second ladder plate 12 are sealed together. Then, the step 14 is fixed between the first ladder plate 11 and the second ladder plate 12 at intervals. The hook 2 and the support frame 3 are fixed to the first ladder plate 11 and the second ladder plate 12 with bolts. Then, the hook 2 at the upper end of the first ladder plate 11 is hung on the upper flange plate of the steel column or the wire rope hook 2. By setting the fixing unit 4, the first ladder plate 11 and the second ladder plate 12 can be quickly and conveniently assembled, simplifying the assembly process, reducing assembly time and labor costs, improving construction efficiency, and the length of the ladder body 1 can be assembled according to the on-site usage requirements to meet different usage needs. The length of the first ladder plate 11 and the second ladder plate 12 is the same, which can be conveniently organized and stored, facilitating the transportation, storage and maintenance of the ladder. When a component is damaged, it can be replaced in time, extending the service life of the ladder.

[0022] In one embodiment, the top plate 41 is symmetrically arranged inside the first ladder plate 11 and the top of the top plate 41 is provided with an inclined plate 411.

[0023] This design is for reference. Figure 9 The jacking plate 41 is symmetrically arranged inside the first ladder plate 11. When assembling the first ladder plate 11 and the second ladder plate 12, the symmetrical jacking plate 41 can more accurately match the corresponding structure on the second ladder plate 12. The inclined plate 411 can improve the stability of the jacking plate 41 and the fixing mechanism 44, thereby improving the stability of the assembly of the first ladder plate 11 and the second ladder plate 12.

[0024] In one embodiment, the pushing mechanism 42 includes: a lifting plate 422, which is vertically and vertically disposed inside the second ladder plate 12; a pushing block 421, disposed on the side of the lifting plate 422 close to the first ladder plate 11; and a first rack 423, disposed on the side of the lifting plate 422 away from the pushing block 421.

[0025] This design is for reference. Figure 12When the top plate 41 is inserted into the second ladder plate 12, the inclined plate 411 contacts the pushing block 421 and drives the pushing block 421 to move upward, which in turn causes the first rack 423 to move upward. The first rack 423 drives the fixing mechanism 44 to move to one side of the second ladder plate 12 through the steering mechanism 43, providing movement space for the inclined plate 411. When the inclined plate 411 is fully inserted into the second ladder plate 12, it pushes the fixing mechanism 44 to move to one side of the inclined plate 411. The fixing mechanism 44 locks the inclined plate 411 into the second ladder plate 12, which simplifies the pushing operation steps in the assembly process, reduces repeated adjustments caused by inaccurate operation, and improves assembly efficiency.

[0026] In one embodiment, a limiting block 4221 is provided at the position where the lifting plate 422 connects with the second ladder plate 12, and a limiting groove 1202 is provided on the second ladder plate 12 for the limiting block 4221 to move.

[0027] This design is for reference. Figure 10 The limiting groove 1202 sets a clear direction of movement for the limiting block 4221, so that the lifting plate 422 can only move up and down within the stroke range specified by the limiting groove 1202, ensuring that the top plate 41 accurately pushes the pushing block 421 into the set position inside the second ladder plate 12, thus ensuring the accuracy and quality of the ladder plate assembly.

[0028] In one embodiment, the side of the push block 421 that is connected to the inclined plate 411 is tilted.

[0029] This design is for reference. Figure 5-7 The inclined plate 411 itself is inclined, and the side of the push block 421 connected to the inclined plate 411 is also inclined, so that the two can fit perfectly during assembly. This tight fit ensures that the inclined plate 411 acts accurately on the push block 421, thereby ensuring that the push block 421 can move inside the second ladder plate 12 in a predetermined direction and position.

[0030] In one embodiment, the steering mechanism 43 includes: a rotating shaft 431 disposed on the inner wall of the second ladder plate 12; a gear 432 sleeved on the rotating shaft 431 and meshing with the first rack 423; a support frame 434 disposed on the inner wall of the second ladder plate 12; a second rack 433 slidably connected to the support frame 434 and meshing with the gear 432; and an adjusting plate 435 disposed on the second rack 433 and connected to the fixing mechanism 44.

[0031] This design is for reference. Figure 5-12The gear 432 meshes with the first rack 423. When the first rack 423 moves with the lifting plate 422, it can accurately convert linear motion into rotational motion of the gear 432, thereby causing the gear 432 to drive the second rack 433 to move inside the support frame 434. The support frame 434 provides a stable track and support for the movement of the second rack 433. When the gear 432 drives the second rack 433 to move, the second rack 433 can slide orderly along the path set by the support frame 434, avoiding shaking and deviation during the movement. During the movement, the second rack 433 drives the fixing mechanism 44 to move towards the inside of the second ladder plate 12 through the adjusting plate 435, providing movement space for the inclined plate 411.

[0032] In one embodiment, a slider 4331 is provided on the side where the second rack 433 is connected to the support frame 434, and a groove 43401 for the slider 4331 to move is provided on the support frame 434.

[0033] This design is for reference. Figure 9 ,as well as Figure 10 The groove 43401 provides a precise guide track for the movement of the slider 4331. When the second rack 433 moves in a straight line as the gear 432 rotates, the slider 4331 slides along the path of the groove 43401, which can ensure that the second rack 433 always moves in the predetermined direction, effectively avoiding the second rack 433 from shaking, deviating or tilting during the movement, making the movement more stable and accurate.

[0034] In one embodiment, the fixing mechanism 44 includes: a insert plate 441, which is adjustablely disposed inside the second ladder plate 12; a top block 442, which is disposed on the top of the insert plate 441; and a positioning groove 44201 for fixing the inclined plate 411 is provided between the insert plate 441 and the top block 442.

[0035] This design is for reference. Figure 10 The insert plate 441 is located inside the second ladder plate 12, and the top block 442 is located on top of the insert plate 441. Together, they form a stable support structure. When the inclined plate 411 is placed into the positioning groove 44201, the inclined plate 411 and the two side walls of the positioning groove 44201 form multi-point contact, making the connection between the inclined plate 411 and the fixing mechanism 44 more stable and less prone to loosening or falling off. The positioning groove 44201 provides a precise positioning space for the inclined plate 411. When installing the inclined plate 411, simply place the inclined plate 411 accurately into the positioning groove 44201 to fix the inclined plate 411 in the set position, thereby ensuring the stability and safety of the ladder structure.

[0036] In one embodiment, the fixing mechanism 44 further includes: a movable rod 443 disposed on one side of the insert plate 441; and a screw 444 disposed on the other side of the insert plate 441, which extends out of the through hole 1201 on the second ladder plate 12 after the insert plate 441 is inserted into the two inclined plates 411 and is fixedly connected to the second ladder plate 12 by a nut.

[0037] This design is for reference. Figure 9-11 The movable rod 443 is set on one side of the insert plate 441, providing the operator with a direct operating point. After the inclined plate 411 is moved to the set position, the operator holds the movable rod 443 and pushes the insert plate 441 to one side of the inclined plate 411, so that the inclined plate 411 is engaged in the positioning groove 44201 on the insert plate 441. Then the screw 444 on the insert plate 441 passes through the through hole 1201 on the second ladder plate 12, and then the nut is tightened on the screw 444, thereby fixing the screw 444 to the second ladder plate 12, completing the fixing work of the first ladder plate 11 and the second ladder plate 12.

[0038] In one embodiment, it further includes: an adjustment unit 5, which includes a fixing block 53 disposed on one side of the ladder body 1, a power member 52 disposed on the fixing block 53, and a fixing lug 51 disposed on the side of the power member 52 away from the ladder body 1 for fixed connection with the steel column.

[0039] This design is for reference. Figure 3 ,as well as Figure 13 The fixing lug 51 is used for fixed connection with the steel column. Its design can flexibly adapt to various steel columns of different specifications and shapes. The fixing block 53 is set on one side of the ladder body 1, providing a stable foundation for the connection between the adjustment unit 5 and the ladder body 1. The power component 52 includes, but is not limited to, hydraulic cylinders, linear guides, electric push rods and air cylinders. Through the telescopic setting of the power component 52, the relative position and angle between the ladder body 1 and the steel column can be adjusted conveniently and quickly, thereby facilitating construction personnel to climb the ladder body 1.

[0040] Furthermore, if the embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relation to the specification. The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
