[0002] In today's era, surveying and mapping technologies are changing with each passing day. Technologies such as photogrammetry, 3D laser scanning, drone oblique photography, neural network imaging, and Gaussian splashing are constantly iterating, updating, and emerging. However, new technologies and new equipment have many limitations, such as high cost of use, insufficient precision, many technical defects in the development cycle, and insufficient applicability. They still cannot completely replace manual surveying and mapping in the engineering field, especially in ancient building protection projects, special projects, and a large number of existing building supplementary measurements in the context of urban renewal. The demand is still expanding today.

[0003] In the field of manual surveying and mapping, traditional ladders, aluminum ladders, lifts and other equipment are usually used as auxiliary tools for surveyors.

[0004] However, some special work scenes and work requirements, such as measurement and photography of ceilings and moldings in indoor halls, close-up measurement and photography of beam structures of ancient buildings, measurement and photography of cliff inscriptions, measurement and photography of grotto temples, etc., these work scenes may be inaccessible to lifts, or traditional ladders may not be able to stand upright and hover, or the structures of ancient buildings and the parts that need to be surveyed are too fragile to be easily supported by ladders, etc. In this case, it will bring great inconvenience to the survey and mapping work and hinder the development of technical work. Summary of the invention

[0037] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0038] like Figure 1-8 As shown, this embodiment provides a survey ladder, which includes a base 10 and a first climbing structure 200 coaxially arranged with the base 10, and the base 10 is sleeved outside the first climbing structure 200, and the first climbing structure 200 can be extended in its axial direction relative to the base 10.

[0039] When using the survey ladder in this embodiment, the base 10 is placed vertically on the ground, and then the first climbing structure 200 is operated to extend the base 10 along the axial direction of the base 10, so that the first climbing structure 200 can be in a higher position. Then, the user can climb in the vertical direction by climbing the base 10 and the first climbing structure 200. When the user reaches a certain height by climbing the base 10 and the first climbing structure 200, it can better meet the user's high-altitude operations.

[0040] It can be understood that, by the combination of the base 10 and the first climbing structure 200, the size of the overall survey ladder is reduced, so that the survey ladder in this embodiment can better enter some construction sites with smaller spaces; further, when the base 10 is placed on the ground, the height of the overall survey ladder in the vertical direction can be increased by operating the first climbing structure 200 mounted in the base 10. When the first climbing structure 200 is extended, the base 10 can support the first climbing structure 200, so that the survey ladder in this embodiment can be suspended in the vertical direction, thereby satisfying the user's need to climb to a certain height position in the vertical direction to perform operations; further, since the survey ladder in this embodiment can be suspended in the vertical direction, it can better avoid contact between the survey ladder and the external building structure, and can also avoid contact between the user on the survey ladder and the external building structure, thereby better protecting the external building structure and avoiding damage to the external building structure.

[0041] In some embodiments, the base 10 includes a second climbing structure 300 and a support seat 100, wherein the support seat 100 is sleeved outside the second climbing structure 300, and the second climbing structure 300 is sleeved outside the first climbing structure 200. Further, the first climbing structure 200 can extend out of the second climbing structure 300 along the axial direction of the second climbing structure 300, and the second climbing structure 300 can extend out of the support seat 100 along the axial direction of the support seat 100.

[0042] It can be understood that after the overall survey ladder is placed on the ground, the first climbing structure 200 can be operated to extend out of the second climbing structure 300, and then the second climbing structure 300 can be operated to extend out of the support seat 100. Of course, the second climbing structure 300 can be operated to extend out of the support seat 100 first, and then the first climbing structure 200 can be operated to extend out of the second climbing structure 300, so that the survey ladder in this embodiment can have a higher height in the vertical direction to meet the needs of the user.

[0043] By dividing the base 10 into the second climbing structure 300 and the support base 100 , the cooperation between the second climbing structure 300 and the first climbing structure 200 on the basis of the support of the support base 100 can further increase the height dimension of the survey ladder in the vertical direction.

[0044] In some embodiments, the first climbing structure 200 is an annular structure, which is formed by at least three vertical rods 210 connected in pairs. In this embodiment, the number of vertical rods 210 is four and the four vertical rods 210 are parallel to each other. In some preferred embodiments, the four vertical rods 210 can also be arranged at an angle, which is not particularly limited. Further, among the four vertical rods 210, two adjacent vertical rods 210 are connected by a plurality of cross rods 220, wherein the number of cross rods 220 can be one or more, and the cross rods 220 can be arranged perpendicular to the vertical rods 210 or at an angle to the vertical rods 210, which is not particularly limited.

[0045] It can be understood that when the first climbing structure 200 is operated to extend the second climbing structure 300, the first climbing structure 200 can increase the height dimension of the overall survey ladder in the vertical direction while also meeting the climbing needs of the user. Specifically, the vertical rod 210 and the horizontal rod 220 on the first climbing structure 200 can both act as grippers, and the user can climb on the first climbing structure 200 by grasping with hands and stepping on with feet, thereby achieving vertical climbing of the user. When the user climbs to a certain height, the first climbing structure 200 can support the user, thereby enabling the user to perform high-altitude operations.

[0046] In some embodiments, the second climbing structure 300 is an annular structure, which is formed by at least three support plates 310 connected in pairs, and a plurality of steps 320 are provided on the circumferential outer wall of the second climbing structure 300, and specifically, the steps 320 are provided on the support plates 310. When the second climbing structure 300 is extended from the support seat 100, the user can climb and operate in the vertical direction through the steps 320 on the support plates 310, and when the first climbing structure 200 is extended from the second climbing structure 300, the user can climb to the first climbing structure 200 through the steps 320, and then continue to climb in the vertical direction through the first climbing structure 200.

[0047] Furthermore, in order to reduce the size of the second climbing structure 300, a recessed groove 311 is also provided on the support plate 310 in the present embodiment, and the step 320 is specifically provided in the recessed groove 311, so that the step 320 can be better hidden, and the size of the second climbing structure 300 in the radial direction can be better reduced.

[0048] In some embodiments, after the support base 100 is placed vertically on the ground, a receiving groove 110 is provided on the circumferential outer wall of the support base 100, and a support leg 120 is provided in the receiving groove 110. Specifically, the other end of the support leg 120 is rotatably connected to the receiving groove 110 through an axial hole or a matching torsion spring, so that one end of the support leg 120 can be rotated out of the receiving groove 110 and abut against the ground, so that the support leg 120 can play an auxiliary supporting role for the support base 100, thereby improving the supporting effect of the support base 100 on the first climbing structure 200 and the second climbing structure 300, and making the overall survey ladder more stable.

[0049] It should be noted that the support leg 120 in this embodiment is a two-section structure whose ends are rotatably connected by a damping shaft, so that the support leg 120 can further adjust its posture after rotating out of the receiving groove 110, so that the support leg 120 can be more stably in contact with the ground, thereby enhancing the auxiliary support effect on the support base 100. At the same time, the rotatable two-section structure can also facilitate the storage of the support leg 120 in the receiving groove 110, and the use is more flexible; of course, the support leg 120 can also be a two-section structure with adjustable length, and there is no special limitation on this, as long as it can stably abut against the ground after moving out of the receiving groove 110 and provide auxiliary support for the support base 100.

[0050] In some embodiments, an avoidance groove 312 is provided on the circumferential outer side wall of the second climbing structure 300 , that is, an avoidance groove 312 is provided on the support plate 310 , and the position of the avoidance groove 312 corresponds to the position of the accommodating groove 110 on the support seat 100 .

[0051] It should be noted that the formation of the receiving groove 110 on the support seat 100 is completed by bending and deforming the support seat 100, that is, while forming the receiving groove 110, the circumferential inner side wall of the support seat 100 further protrudes inward to form the track 130, so that the receiving groove 110 can have enough space to store the support leg 120. When assembling the support seat 100 and the second climbing structure 300, it is necessary to align the position of the avoidance groove 312 on the second climbing structure 300 with the position of the track 130 on the support seat 100, so that when the support seat 100 is sleeved on the second climbing structure 300, the track 130 can extend into the avoidance groove 312.

[0052] It is worth mentioning that the cooperation between the track 130 and the avoidance groove 312 can further improve the stability of the second climbing structure 300 moving along the axial direction of the support seat 100. Specifically, after assembling the support seat 100 and the second climbing structure 300, the track 130 extends into the avoidance groove 312, so that the track 130 and the avoidance groove 312 can achieve mutual clamping and limiting. In the process of operating the second climbing structure 300 to extend out of the support seat 100, the avoidance groove 312 will only move along the extension direction of the track 130, which can better avoid the second climbing structure 300 and the support seat 100 from shaking in the circumferential direction, and can better improve the stability of the overall structure.

[0053] Furthermore, in order to make the overall structure of the second climbing structure 300 and the support seat 100 more compact after assembly, the avoidance groove 312 is specifically opened on the inner wall of the recessed groove 311, so that the recessed groove 311 can hide the step 320 on the one hand, and can cooperate with the avoidance groove 312 to accommodate the guide rail on the other hand.

[0054] In some embodiments, in combination Figure 8 As shown, a shoulder strap 140 is provided on the circumferential outer wall of the support seat 100. The number of the shoulder straps 140 is not limited. The shoulder straps 140 enable the user to better apply force to the entire survey ladder, thereby facilitating the movement of the survey ladder and making it more convenient to use.

[0055] In some embodiments, in combination Figure 3 As shown, a seat plate 230 is also provided on the first climbing structure 200, and the seat plate 230 is detachably mounted on at least two cross bars 220. Specifically, after the user climbs onto the first climbing structure 200, the user can operate the seat plate 230 to adjust the height of the seat plate 230 so that the seat plate 230 is mounted on at least two cross bars 220 with a certain height, thereby allowing the seat plate 230 to be placed basically horizontally, and then the user can sit on the seat plate 230 to meet the application needs in more scenarios.

[0056] Furthermore, a corresponding hook 231 may be provided on the seat plate 230 , so that the seat plate 230 can be hung on the cross bar 220 through the hook 231 , so as to achieve a stable connection between the seat plate 230 and the cross bar 220 and prevent the seat plate 230 from falling off.

[0057] In some embodiments, a first buckle 211 is disposed on the vertical rod 210 of the first climbing structure 200 , and the first buckle 211 can elastically extend to the circumferential outer side wall of the first climbing structure 200 .

[0058] The first lifting structure 200 is preferably mounted on the support frame 310 and the second lifting structure 300 is preferably mounted on the support frame 310. The first lifting structure 200 is preferably mounted on the support frame 310 and the second lifting structure 300 is preferably mounted on the support frame 310.

[0059] It is understandable that in some preferred embodiments, combined with Figure 4 As shown, the first buckle 211 includes a first abutment plate 212 and a first spring 213 . The upper end of the first abutment plate 212 is rotatably connected to the vertical rod 210 , and the lower end of the first abutment plate 212 is connected to the vertical rod 210 via the first spring 213 . When pressure is applied to the lower end of the first abutment plate 212, the lower end of the first abutment plate 212 is brought close to the vertical rod 210 by compressing the first spring 213, thereby releasing the abutment between the first abutment plate 212 and the second climbing structure 300, so that the first climbing structure 200 can be moved into the second climbing structure 300; when the first climbing structure 200 is operated to extend the second climbing structure 300, so that the lower end of the first abutment plate 212 is exposed to the second climbing structure 300, the lower end of the first abutment plate 212 will protrude from the circumferential outer surface of the first climbing structure 200 under the action of the first spring 213, and then under the action of gravity, the lower end of the first abutment plate 212 will abut against the second climbing structure 300, thereby better keeping the first climbing structure 200 in an extended state.

[0060] Of course, when the first climbing structure 200 extends out of the second climbing structure 300, it can also be fixed to the second climbing structure 300 by means of bolts or buckles to keep the first climbing structure 200 in an extended state, and there is no special limitation on this.

[0061] In some embodiments, a second buckle 313 is disposed on the support plate 310 of the second climbing structure 300 , and the second buckle 313 can elastically extend to the circumferential outer side wall of the second climbing structure 300 .

[0062] It should be further explained that, when the second climbing structure 300 is mounted in the support seat 100, the second buckle 313 is elastically compressed. When the second climbing structure 300 is operated to extend out of the support seat 100, when the second buckle 313 is fully extended out of the support seat 100, the second buckle 313 is no longer compressed by the support seat 100, so that the second buckle 313 is elastically extended to the circumferential outer wall of the second climbing structure 300. At this time, the second climbing structure 300 is no longer operated to continue to extend out of the support seat 100. The second buckle 313 will abut against the support seat 100 under the action of gravity of the second climbing structure 300, thereby preventing the second climbing structure 300 from falling back into the support seat 100 under the action of gravity, and can better keep the second climbing structure 300 in an extended state, thereby satisfying the user's climbing needs.

[0063] It is understandable that in some preferred embodiments, combined with Figure 6 As shown, the second buckle 313 includes a second abutment plate 314 and a second spring 315 . The upper end of the second abutment plate 314 is rotatably connected to the support plate 310 , and the lower end of the second abutment plate 314 is connected to the support plate 310 via the second spring 315 . When pressure is applied to the lower end of the second abutment plate 314, the lower end of the second abutment plate 314 is brought close to the support plate 310 by compressing the second spring 315, thereby releasing the abutment between the second abutment plate 314 and the support seat 100, so that the second climbing structure 300 can be moved into the support seat 100; when the second climbing structure 300 is operated to extend out of the support seat 100, so that the lower end of the second abutment plate 314 is exposed from the support seat 100, the lower end of the second abutment plate 314 will protrude from the circumferential outer surface of the second climbing structure 300 under the action of the second spring 315, and then under the action of gravity, the lower end of the second abutment plate 314 will abut against the support seat 100, thereby better maintaining the second climbing structure 300 in an extended state.

[0064] Furthermore, in this embodiment, the second buckle 313 is arranged in the avoidance groove 312. When the second climbing structure 300 is operated to extend out of the support seat 100 so that the second buckle 313 is completely exposed from the support seat 100, under the action of gravity, the second buckle 313 can abut against the guide rail, thereby maintaining the extended state of the second climbing structure 300.

[0065] Of course, when the second climbing structure 300 extends out of the support seat 100, it can also be fixed to the support seat 100 by means of bolts or buckles to keep the second climbing structure 300 in an extended state, and there is no special limitation on this.

[0066] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
