[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figures 1 to 5 As shown, the aerial work ladder 100 of the embodiment of the present invention includes a first ladder 1, a second ladder 2, a telescopic member 3 and a clamping member 4, one end of the first ladder 1 and one end of the second ladder 2 are rotatably connected, one end of the telescopic member 3 is connected to the first ladder 1, and the other end of the telescopic member 3 is detachably connected to the second ladder 2, the clamping member 4 is arranged at the other end of the second ladder 2, and the clamping member 4 is provided with a clamping clamp 43, and the clamping clamp 43 is used to clamp the column 200.

[0029] When the climbing work ladder 100 of the embodiment of the present invention is used at a photovoltaic module construction site, the other end of the telescopic member 3 is connected to the second ladder 2, and the telescopic member 3 is extended to unfold the first ladder 1 and the second ladder 2, and then the climbing work ladder 100 is erected, so that the other end of the first ladder 1 is against the ground, and the holding member 4 is supported by the column 200, and then the postures of the first ladder 1 and the second ladder 2 are adjusted to make the second ladder 2 in a horizontal state, such as Figure 1 As shown, the angle between the lower end of the first ladder 1 and the ground is 60°, and the angle between the second ladder 2 and the first ladder 1 is 120°, and then the first ladder 1 is pushed in the direction of the column 200, so that the clamping clamps of the clamping member 4 clamp the column 200 of the photovoltaic bracket, and the other end of the first ladder 1 is made to abut the ground, thereby completing the erection of the aerial work ladder 100.

[0030] It should be noted that when adjusting the posture of the second ladder 2, if there is an angle between the second ladder 2 and the horizontal direction, for example, the angle between the second ladder 2 and the horizontal direction is 2°, although the second ladder 2 is inclined relative to the horizontal direction, if the degree of inclination does not affect the personnel standing on the second ladder 2 to work, then the inclination is acceptable and does not affect the second ladder 2 as a working platform.

[0031] A person can climb up the second ladder 2 through the first ladder 1, and work on the second ladder 2. The second ladder 2 in the horizontal direction forms a working platform, so the person can move on the second ladder 2, thereby increasing the working area of ​​the person on the second ladder 2. Moreover, after the person stands on the second ladder 2, the second ladder 2 is subjected to a downward force, which causes the second ladder 2 to deform, so that both ends of the second ladder 2 form a downward and outward force, see Figure 1 , a force toward the right and downward is formed at the one end (right end) of the second ladder 2, and a force toward the left and downward is formed at the other left end of the second ladder 2. For the one end of the second ladder 2, the first ladder 1 supports and fixes the one end of the second ladder 2, and for the other end of the second ladder 2, the existing column 200 supports and fixes the other end of the second ladder 2. The force toward the left and downward is formed at the other end (left end) of the second ladder 2, which increases the interaction force between the clamping member 4 at the other end of the second ladder 2 and the existing column 200, thereby increasing the clamping and fixing effect of the clamping member 4 on the existing column 200, making the climbing work ladder 100 more stable.

[0032] After the use of the climbing work ladder 100 is finished, the clamping jaws 43 of the clamping member 4 are separated from the existing column 200, the other end of the telescopic member 3 is separated from the second ladder 2, and the climbing work ladder 100 can be stored by folding the first ladder 1 and the second ladder 2. After the first ladder 1 and the second ladder 2 are folded, the climbing work ladder 100 can also be used as a straight ladder.

[0033] The climbing work ladder 100 of the embodiment of the present invention clamps the existing column 200 through the clamping member 4, so that the existing column 200 becomes one of the fulcrums of the climbing work ladder 100. The existing column 200 and the first ladder 1 work together to enable the second ladder 2 to be arranged in a horizontal direction, so that the second ladder 2 can be used as a work platform for personnel, providing a larger space for personnel to work at heights, increasing the area of ​​the personnel's working area, and enabling more high-altitude work, thereby reducing the frequency of personnel going up and down the ladder and improving the personnel's work efficiency. In addition, after the personnel climb up the second ladder 2 of the climbing work ladder 100 of the embodiment of the present invention, the force of the clamping member 4 on the existing column 200 is increased, and the clamping effect of the clamping member 4 on the existing column 200 is good, so that the climbing work ladder 100 of the embodiment of the present invention has good stability.

[0034] Therefore, the aerial work ladder 100 of the embodiment of the present invention has good stability and can lean against the column 200 to form a working platform for the second ladder 2, providing a larger support area for personnel, increasing the working area of ​​personnel, and thus improving the working efficiency of personnel.

[0035] In some embodiments, the other end of the first ladder 1 is provided with a first metal anti-skid pad 11. For soil ground, the first metal anti-skid pad 11 is not easy to deform and has a relatively high hardness. The first metal anti-skid pad 11 can be inserted into the soil ground to a certain depth, and the other end of the first ladder 1 has a relatively large contact area with the ground, thereby improving the stability of the other end of the first ladder 1, thereby further improving the stability of the aerial work ladder 100 of the embodiment of the present invention during operation.

[0036] Specifically, Figure 2 As shown, a mounting groove is provided on one side of the first metal anti-skid foot pad 11, and the other end of the first ladder 1 is fitted in the mounting groove. A plurality of toothed anti-skid strips 111 are provided on the other side of the first metal anti-skid foot pad 11. The toothed anti-skid strips 111 can further increase the contact area between the first metal anti-skid foot pad 11 and the ground, increase the grip of the first metal anti-skid foot pad 11, and improve the stability of the one end of the first ladder, thereby improving the stability of the aerial work ladder 100 of the embodiment of the present invention during operation.

[0037] In some embodiments, a buckle 12 is provided on the first ladder 1, and the buckle 12 has a slot to fasten the other end of the telescopic member 3. When the climbing work ladder 100 of the embodiment of the present invention needs to be stored, the other end of the telescopic member 3 is separated from the second ladder 2, and the other end of the telescopic member 3 is moved to the position of the buckle 12, and the other end of the telescopic member 3 is fastened to the slot, thereby fixing the telescopic member 3 and preventing the telescopic member 3 from shaking, thereby improving the integrity and safety of the storage state of the climbing work ladder 100 of the embodiment of the present invention.

[0038] Specifically, the telescopic member 3 is a hydraulic strut.

[0039] Specifically, a first pin hole is provided on the second ladder 2, and a second pin hole is provided on the other end of the telescopic member 3. When the other end of the telescopic member 3 needs to be connected to the second ladder 2, the second pin hole is opposite to the first pin hole, and a pin shaft is used to pass through the first pin hole and the second pin hole to fix the telescopic member 3 and the second ladder 2.

[0040] In some embodiments, Figure 3 and Figure 4 As shown, the holding member 4 includes an elastic connecting plate 41 and a flexible belt 42. The elastic connecting plates 41 have two, and the two elastic connecting plates 41 are respectively arranged on the second ladder 2 in its width direction (for example Figure 3The two ends of the flexible belt 42 are respectively connected to the two elastic connecting plates 41, and the flexible belt 42 forms a clamping opening 43 to clamp the existing column 200.

[0041] When the clamping member 4 abuts against and clamps the existing column 200, the personnel can adjust the unfolded state of the flexible belt 42 so that one side of the flexible belt 42 in the thickness direction faces the existing column 200, such as Figure 3 As shown, the first ladder 1 is then pushed toward the direction of the column 200, so that the flexible belt 42 is deformed with the shape of the column 200 to form a clamping clamp 43, as shown in FIG. Figure 4 As shown, the flexible belt 42 abuts against the existing column 200, so that there is a large interaction force between the flexible belt 42 and the existing column 200, so that the flexible belt 42 clamps the existing column 200. At the same time, in the process of the flexible belt 42 tightly clamping the existing column 200, as the flexible belt 42 is deformed in contact with the existing column 200, the two ends of the flexible belt 42 are close to each other, so that the two elastic connecting plates 41 are close to each other, forming a state in which the two elastic connecting plates 41 and the flexible belt 42 surround the existing column 200, as shown in FIG. Figure 4 When the climbing work ladder 100 is subjected to a force in the direction of the existing column 200, and / or when a force in the direction of the existing column 200 is formed at the other end of the second ladder 2, the interaction force between the clamping member 4 and the existing column 200 increases, so that the clamping and fixing effect of the flexible belt 42 on the existing column 200 is increased, making the climbing work ladder 100 more stable.

[0042] The flexible belt 42 of the embodiment of the present invention is flexible and can form different shapes when it fits the existing columns 200 of different shapes, so that it can adapt to the existing columns 200 of different shapes, improve the adaptability of the clamping member 4, and improve the applicability of the climbing work ladder 100 of the embodiment of the present invention. For example, if the existing column 200 is cylindrical, the existing column 200 has an arc-shaped surface, and the part of the flexible belt 42 that fits the existing column 200 forms an arc segment, that is, forms a clamping clamp 43 with an arc segment.

[0043] At the same time, the elastic connecting plate 41 of the embodiment of the present invention has a certain deformation ability. While realizing the fixed connection between the flexible belt 42 and the second ladder 2, it can produce a corresponding deformation amount according to the force applied to the flexible belt 42, so that the positions of the two ends of the flexible belt 42 have a variable space, so that the flexible belt 42 can have a larger fitting area with the existing column 200, thereby ensuring the clamping and clamping effect of the clamping member 4 on the existing column 200, and ensuring the stability of the aerial work ladder 100 of the embodiment of the present invention.

[0044] Moreover, the holding member 4 of the embodiment of the present invention has a simple structure, and the process of the holding member 4 clamping and holding the existing column 200 is simple. When the climbing work ladder 100 needs to be separated from the existing column 200, the personnel can move the climbing work ladder 100 in a direction away from the existing column 200. When the existing column 200 against which the climbing work ladder 100 abuts remains unchanged but the position and direction of the second ladder 2 need to be adjusted, the climbing work ladder 100 can be rotated and moved around the existing column 200, which is simple and convenient to operate.

[0045] In some embodiments, the other end of the second ladder 2 has a groove 21, the groove 21 is open at one end facing away from the second ladder 2, and the depth direction of the groove 21 is parallel to the extension direction of the second ladder 2 (length direction, for example Figure 3 and Figure 4 The left and right directions of the groove 21 are the same, one end of the elastic connecting plate 41 is connected to the side wall surface of the groove 21, and the other end of the elastic connecting plate 41 faces the opening of the groove 21. In other words, the other end of the elastic connecting plate 41 is located on the inner side of the opening of the groove 21, and in the extension direction of the second ladder 2, the other end of the elastic connecting plate 41 does not extend out of the second ladder 2, and the other end of the elastic connecting plate 41 will not interfere with the contact between the other end of the second ladder 2 and the plane. Then, when the climbing work ladder 100 of the embodiment of the present invention is not against the column 200, the length of the telescopic member 3 is adjusted, and the angle between the second ladder 2 and the first ladder 1 is adjusted, so that the other end of the second ladder 2 and the other end of the first ladder 1 touch the ground at the same time, and the second ladder 2 and the first ladder 1 form a herringbone ladder, that is, the climbing work ladder 100 of the embodiment of the present invention can also be used as a herringbone ladder, thereby improving the function of the climbing work ladder 100 of the embodiment of the present invention, increasing the applicable scenes of the climbing work ladder 100 of the embodiment of the present invention, and improving the applicability of the climbing work ladder 100 of the embodiment of the present invention.

[0046] In some embodiments, the elastic connecting plate 41 is a steel plate, which has high strength, can also produce a certain amount of deformation, and has low cost, which is conducive to reducing the cost of the aerial work ladder 100 of the embodiment of the present invention.

[0047] In some embodiments, the two elastic connecting plates 41 are symmetrically arranged with the symmetry center of the groove 21 as the symmetry center, and the two ends of the flexible belt 42 are respectively connected to the other ends of the two elastic connecting plates 41, and the middle of the flexible belt 42 faces the bottom wall of the groove 21. The elastic connecting plates 41 and the flexible belt 42 are symmetrically distributed. When the flexible belt 42 is attached to the existing column 200, it is beneficial to evenly distribute the force on the flexible belt 42, and it is beneficial to make the two elastic connecting plates 41 receive the same force, thereby improving the service life of the flexible belt 42 and the elastic connecting plate 41, and it is beneficial to improve the service life of the climbing work ladder 100 of the embodiment of the present invention.

[0048] In some embodiments, the flexible belt 42 includes a canvas belt and / or a rubber belt.

[0049] In this embodiment, the flexible belt 42 includes a canvas belt. The canvas belt has low cost and good toughness, which is conducive to reducing the cost of the aerial work ladder 100 of the embodiment of the present invention.

[0050] In some other embodiments, the flexible belt 42 includes a rubber belt. The rubber belt has a large friction force and can maintain the stability of the flexible belt 42 when it is clamped and tightly embraced with the column 200.

[0051] In some other embodiments, the flexible belt 42 includes a canvas belt and a rubber belt. The rubber belt is arranged on one side of the canvas belt adjacent to the column 200 in the thickness direction of the canvas belt. The combination of the canvas belt and the rubber belt can improve the toughness and friction of the flexible belt 42, which is beneficial to ensure the stability of the clamping and holding of the flexible belt 42 and the column 200, and is beneficial to improving the operating stability of the aerial work ladder 100 of the embodiment of the present invention.

[0052] In some embodiments, the second ladder 2 is a telescopic ladder. The length of the second ladder 2 is adjustable. When the climbing work ladder 100 is used against the existing column 200, the distance between the first ladder 1 and the existing column 200 can be adjusted by adjusting the length of the second ladder 2, thereby adjusting the space occupied by the climbing work ladder 100, thereby improving the flexibility of the climbing work ladder 100 and the adaptability to the working environment.

[0053] In some embodiments, Figure 5 As shown, the second ladder 2 includes a first ladder section 22, a second ladder section 23 and a connecting member 24, one end (right end) of the first ladder section 22 forms the one end of the second ladder 2, the second ladder section 23 is slidably arranged on the first ladder section 22 along the extension direction of the second ladder 2, the connecting member 24 connects the second ladder section 23 and the first ladder section 22 to fix the second ladder section 23 and the first ladder section 22, one end of the second ladder section 23 is away from one end of the first ladder section 22, and one end (left end) of the second ladder section 23 forms the other end of the second ladder 2. When the length of the second ladder 2 needs to be adjusted, the connecting member 24 is separated from the first ladder section 22 and the second ladder section 23, and then the second ladder section 23 is moved. When the second ladder section 23 is adjusted to the right position, the connecting member 24 is connected to the first ladder section 22 and the second ladder section 23 to fix the first ladder section 22 and the second ladder section 23. The telescopic adjustment structure of the second ladder 2 is simple, and the adjustment process is manually operated, which is low-cost and helps to reduce the manufacturing cost of the climbing work ladder 100 of the embodiment of the present invention and reduce the weight of the climbing work ladder 100.

[0054] For details, see Figure 5The first ladder section 22 is provided with a first mounting hole, and the second ladder section 23 is provided with a plurality of second mounting holes 231, and the first mounting hole corresponds to one of the second mounting holes 231. The connecting member 24 includes a mounting shell 241, a locking rod 242, a spring 243 and a pin 244. The mounting shell 241 has two springs 243, the lower end of the spring 243 is connected to the mounting shell 241, and the two sides of the locking rod 242 are respectively connected to the upper ends of the two springs 243. The lower end of the pin 244 is slidably arranged on the mounting shell 241, and the pin 244 is arranged in the spring 243. The middle part of the pin 244 is fixedly connected to the locking rod 242. The two mounting shells 241 are respectively arranged on both sides of the first ladder section 22 in the width direction, and the mounting shell 241 is located at the lower side of the second ladder section 22. The upper end of the pin 244 passes through the first mounting hole and the second mounting hole 231, so as to realize the fixed connection between the first ladder section 22 and the second ladder section 23.

[0055] When it is necessary to slide the second ladder 23 to adjust the length of the second ladder 2, pull the locking rod 242 downward to move the pin 244 downward, withdraw the upper end of the pin 244 from the second mounting hole 231 and the first mounting hole, and then slide the second ladder 23. When the second ladder 23 slides into place, release the locking rod 242. Under the action of the elastic force of the spring 243, the pin 244 moves upward and is inserted into the first mounting hole and the second mounting hole 231, fixing the first ladder 22 and the second ladder 23, and completing the adjustment of the length of the second ladder 2.

[0056] The connecting member 24 has a simple structure, is easy to use, can be operated by one person, and is not easily separated from the first ladder section 22, which helps to improve the ease of use of the aerial work ladder 100 of the embodiment of the present invention.

[0057] In some embodiments, the other end of the second ladder 2 is provided with a second metal anti-slip foot pad (not shown in the figure), so as to improve the stability of the aerial work ladder 100 of the embodiment of the present invention when used as a herringbone ladder.
