[0034] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the following will further describe the schemes of the present application. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; Obviously, the examples in the specification are only some of the embodiments of the present application, not all the embodiments.

[0036] As Figure 1 ​As shown, the ladder climbing device comprises inclined rods 1, cross beams 2, fixing seats 3 and connecting seats 4. The inclined rods 1 are two, hollow at the ends, parallel and spaced apart, and can be adjusted in length to adapt to different pile foundations 100. The cross beams 2 are multiple, arranged between the two inclined rods 1 and horizontally connected to the two inclined rods 1, serving as steps for workers to climb. The fixing seat 3 is arranged at the end of the inclined rod 1, i.e. the end close to the ground, and is used for fixed connection with the ground. Specifically, the fixing seat 3 comprises a drill bit 31, a first fastening bolt 32 and a first fastening nut 33. The drill bit 31 has a through hole 311 at one end and can be pierced into the ground at the other end. The end of the inclined rod 1 is hollow, and a through hole is radially formed through the inclined rod 1, and the first fastening bolt 32 can pass through the through hole and the through hole 311 to be connected with the first fastening nut 33. The connecting seat 4 is installed on the cross beam 2, preferably on the cross beam 2 at the top, and can be detachably connected with the pile foundation 100.

[0037] In use, the ladder climbing device is leaned against the pile foundation 100 at a suitable angle, with the uppermost cross beam 2 closely attached to the pile foundation 100. Then, according to the terrain where the ladder climbing device is located, the lengths of the two inclined rods 1 are adjusted respectively, so that the fixing seat 3 can just contact the ground and the cross beams 2 are in a horizontal position. For example, when the terrain is a sloping section, the lengths of the two inclined rods 1 are different, and when the terrain is a flat section, the lengths of the two inclined rods 1 are the same. Then the drill bit 31 is manually screwed into the ground, and after the drill bit 31 is fixed, the first fastening bolt 32 is passed through the through hole at the end of the inclined rod 1 and the through hole 311 at one end of the drill bit 31 to be connected with the first fastening nut 33, so as to fixedly connect the inclined rod 1 with the fixing seat 3. The ladder climbing device can be tightly fixed to the ground, and then the worker climbs onto the ladder climbing device to connect the connecting seat 4 at the top of the device with the pile foundation 100, preventing the whole ladder climbing device from toppling over and achieving stable support.

[0038] The ladder climbing device connects the whole device with the ground by means of the drill bit 31 and connects the pile foundation 100 by means of the connecting seat 4, so that the ladder climbing device can form stable support, improving the overall stability of the ladder climbing device and achieving stable support even in crosswind environment. Moreover, the lengths of the two inclined rods 1 can be adjusted, so that the ladder climbing device can adapt to undulating terrain conditions and complex terrain environment, ensuring smooth and safe construction process.

[0039] Alternatively, as shown in FIG. 6, the drill bit 31 is replaced by a bolt 31, and the through hole 311 is replaced by a threaded hole 311. The first fastening bolt 32 is replaced by a threaded fastening bolt 32, and the first fastening nut 33 is replaced by a threaded fastening nut 33. Figure 2As shown, the inclined rod 1 of the embodiment comprises a first inclined rod 11, a second inclined rod 12, a second fastening bolt 13 and a second fastening nut 14. The fixing seat 3 is arranged at the end of the second inclined rod 12. The first inclined rod 11 and the second inclined rod 12 are provided with a plurality of adjusting holes 15 along the length direction. When adjusting the length of the inclined rod 1, the second fastening bolt 13 and the second fastening nut 14 are first removed, then the second inclined rod 12 is pulled out, and after being pulled out to the appropriate length, the second fastening bolt 13 is aligned through the adjusting holes 15 on the first inclined rod 11 and the second inclined rod 12, and then the second fastening nut 14 is assembled to the second fastening bolt 13, so as to realize the length adjustment of the inclined rod 1. In addition, other structural forms can also be used to achieve the purpose of length adjustment of the inclined rod 1, including but not limited to the mode shown in the embodiment.

[0040] Optionally, as shown in Figure 3 and Figure 4 , the connecting seat 4 comprises a hoop 41 and a connecting piece 42, one end of the connecting piece 42 is connected with the cross beam 2, the other end is connected with the hoop 41, and the hoop 41 can be detachably fixed on the pile foundation 100. In the embodiment, since the pile foundation 100 is mostly in the form of a cylinder, in order to firmly fix the connecting seat 4 with the pile foundation 100, the hoop 41 is used to detachably fix the pile foundation 100, and the shape and size of the hoop 41 are related to the shape and size of the pile foundation 100. The hoop 41 is connected with the cross beam 2 through the connecting piece 42. Optionally, one end of the connecting piece 42 is rotatably connected with the hoop 41 through a pin shaft, and the other end is rotatably connected with the cross beam 2 through a pin shaft, so as to facilitate the assembly of the hoop 41.

[0041] Further, the hoop 41 of the embodiment comprises a first hoop 411 and a second hoop 412, and the first hoop 411 and the second hoop 412 can be connected in the following two ways. Way one: one end of the first hoop 411 is rotatably connected with the second hoop 412, and the other end is detachably connected with the second hoop 412 through a bolt fastener or the like. When in use, the first hoop 411 and the second hoop 412 are first unlocked, then the first hoop 411 or the second hoop 412 is rotated to wrap around the outer periphery of the pile foundation 100, and then the first hoop 411 and the second hoop 412 are fixed by using the fastener. Scheme two: the two ends of the first hoop 411 and the two ends of the second hoop 412 are detachably connected through a fastener. Any connection mode can be selected according to the actual situation, and the specific structure of the hoop 41 is not described in detail in the embodiment.

[0042] Optionally, as shown in Figure 5As shown, the drill bit 31 of the embodiment is provided with a base disc 313 on the outer periphery. On the one hand, the base disc 313 can increase the contact area with the ground, prevent the inclined rod 1 from sinking below the ground under pressure during operation, and ensure that the height of the inclined rod 1 remains unchanged during operation. On the other hand, the operator can hold the base disc 313 to rotate the drill bit 31 as a whole when rotating the drill bit 31, thereby providing a fulcrum for rotating the drill bit 31.

[0043] Further, as shown, the end of the second inclined rod 12 is bent towards the ground to form a bent portion 121, and the fixing seat 3 is arranged at the bent portion 121, so that the whole ladder body is in an inclined state and is suitable for leaning against the pile foundation 100. Figure 1

[0044] Optionally, in the embodiment, in order to enable the drill bit 31 to be effectively fixed to the ground, the drill bit 31 of the embodiment can adopt the following structural schemes.

[0045] Scheme one: an external thread is arranged on the outer periphery of the drill bit 31, so that the drill bit 31 can be deeply screwed into the ground.

[0046] Scheme two: a pointed end portion 312 is formed at the end of the drill bit 31, so that the pointed end portion 312 can be deeply inserted into the ground. Specifically, as shown, the pointed end portion can be a conical structure 3121 with a radial dimension gradually decreasing away from the inclined rod 1. In use, the drill bit 31 is pressed down, and the conical structure 3121 of the pointed end portion is pressed into the ground. This type of geological drill bit 31 does not need to provide a high anti-pulling friction force, and the drill bit type with the conical structure 3121 can be more convenient to assemble and disassemble. Further, as shown, the structure of the pointed end portion 312 can also be a helical member 3122 extending helically away from the inclined rod 1. The helical structure can provide a strong anti-pulling friction force, and is suitable for use in soft geological desert areas. Depending on the use environment, the appropriate drill bit type can be selected and replaced at any time. Figure 5 Figure 6
