[0032] Please refer to Figure 1 and Figure 2The folding ladder provided by the embodiment of the present application is described as follows. The folding ladder provided by the embodiment of the present application comprises a connecting assembly 1, a folding assembly 2, and a supporting assembly 3. The connecting assembly 1 is used to be connected with an external device. The folding assembly 2 is rotationally connected with the connecting assembly 1. The folding assembly 2 comprises a plurality of rotatable steps 21. The connecting assembly 1 can be rotationally stacked on the folding assembly 2. The supporting assembly 3 is rotationally connected with the folding assembly 2. The supporting assembly 3 is used to support the folding assembly 2. The supporting assembly 3 can be rotationally stacked on the folding assembly 2.

[0033] The folding ladder provided by the embodiment of the present application is used for internal maintenance and inspection of a laser cutting device or other large-format devices.

[0034] The connecting assembly 1 is used to fix the folding ladder on the side wall of the external device (such as a laser cutting device). The connecting assembly 1 can comprise a fixing plate and a plurality of connecting bolts. The shape of the fixing plate is matched with the opening of the side wall of the device. The fixing plate is firmly installed on the side wall of the device through the connecting bolts. The connecting assembly 1 is also provided with a rotating shaft, which is used to be rotationally connected with the folding assembly 2, so as to ensure that the folding ladder can be flexibly switched between the unfolded state and the folded state.

[0035] The folding assembly 2 is used to support the weight of the maintenance personnel and provide a passage to go up and down the device. The folding assembly 2 comprises a plurality of rotatable steps 21. The steps 21 are connected together through rotating shafts, forming a foldable ladder structure. The steps 21 can be made of high-strength aluminum alloy material. The surface can be treated to prevent slipping, so as to ensure the safety of the maintenance personnel during use. The size of the steps 21 is designed according to the internal space of the device and the needs of the maintenance personnel. The two ends of the folding assembly 2 are rotationally connected with the connecting assembly 1 and the supporting assembly 3 through rotating shafts, so that the folding assembly 2 can be freely switched between the unfolded state and the folded state.

[0036] The supporting assembly 3 is used to provide stable support when the folding ladder is unfolded, so as to ensure the structural strength and stability of the folding ladder. The supporting assembly 3 can comprise two telescopic supporting rods. One end of the supporting rod is rotationally connected with the bottom of the folding assembly 2, and the other end is in contact with the side wall of the device or the ground. The supporting rod can be made of high-strength steel material and has good compression resistance. The supporting assembly 3 can also be provided with a locking device. When the folding ladder is unfolded, the locking device can fix the supporting rod at a proper position, so as to prevent the folding ladder from shaking during use. When the folding ladder needs to be folded, the supporting rod can be retracted and rotationally stacked on the folding assembly 2, so as to reduce the occupied space of the folding ladder.

[0037] When it is necessary to enter the device for maintenance or inspection, the maintenance personnel first unfolds the folding ladder. The folding assembly 2 and the supporting assembly 3 are rotated, so that the folding ladder is switched from the folded state to the unfolded state. At this time, the locking device of the supporting assembly 3 is automatically locked, so as to ensure the stability of the folding ladder.

[0038] The maintenance personnel enter the interior of the equipment through the steps 21 of the folding ladder to perform maintenance or inspection work. After the maintenance or inspection work is completed, the maintenance personnel leave the interior of the equipment through the folding ladder. Then, the connecting assembly 1, the supporting assembly 3 and the folding assembly 2 are rotated and stacked together, and the folding ladder is stored to reduce the occupied space.

[0039] When the folding ladder is not used, the folding ladder is switched from the unfolded state to the storage state by rotating the connecting assembly 1 and the supporting assembly 3. The steps 21 of the folding assembly 2 can be stacked with each other, and the supporting assembly 3 can also be contracted and stacked on the folding assembly 2, so that the volume of the folding ladder is greatly reduced. This design not only facilitates the entry and exit of the maintenance personnel, but also avoids the problem that the traditional ladder occupies the interior space of the equipment, thereby improving the utilization rate of the interior space of the equipment. The folding ladder of the embodiment of the present application achieves the goal of facilitating the entry and exit of the maintenance personnel into the interior of the equipment without increasing the size of the equipment. The unfolding and storage process of the folding ladder is simple and fast, and the maintenance personnel can complete the switching operation of the folding ladder in a short time, thereby improving the maintenance efficiency. In addition, the folding ladder has a reasonable structure design, good stability and safety, and can meet the strict requirements of industrial equipment maintenance and inspection.

[0040] The folding assembly 2 further comprises a support 22, a pulling member 23 and a fixing member 24. The connecting assembly 1 and the supporting assembly 3 are rotationally connected with the support 22, and the two sides of the plurality of steps 21 are rotationally installed on the support 22. The plurality of steps 21 are rotationally connected with the pulling member 23. One end of the fixing member 24 is rotationally connected with the pulling member 23, and the other end of the fixing member 24 is rotationally connected with the support 22.

[0041] The support 22 comprises left and right support rods arranged in parallel opposite to each other, and the steps 21 are rotationally arranged between the left and right support rods through a rotating shaft. When the folding assembly 2 is stored, the steps 21 can be rotated to be in the same plane as the left and right support rods. When the folding assembly 2 is unfolded, the pulling member 23 can be pulled to rotate the plurality of steps 21 at the same time. The fixing member 24 can limit the rotation angle of the steps 21. Under the action of the fixing member 24, the angle between the receiving surface of the step 21 and the length direction of the left or right support rod is fixed at 50-80°, and is preferably 70°, to support the maintenance personnel. The pulling member 23 can be a pull rod, and the fixing member 24 can be a zipper or a pull rod, and is preferably a pull rod.

[0042] When the fixing member 24 is a pull rod, a sliding groove 241 is arranged on the fixing member 24, and the connecting end of the pulling member 23 is slidingly arranged in the sliding groove 241.

[0043] The connecting end of the pulling member 23 and the fixing member 24 can be slidingly arranged in the sliding groove 241, so as to prevent the fixing member 24 from protruding outward when the folding assembly 2 is stored, thereby further reducing the occupied space of the folding assembly 2.

[0044] The folding assembly 2 further comprises a support slope 25 arranged at one end of the support frame 22 close to the connecting assembly 1, and the support slope 25 is used to support the connecting assembly 1.

[0045] The connecting assembly 1 comprises a receiving member 11 and a connecting member 12 connected with an external device, the receiving member 11 is connected with the connecting member 12, and the receiving member 11 is rotationally connected with the support slope 25.

[0046] When the folding ladder is unfolded, the receiving member 11 of the connecting assembly 1 can be rotated onto the support slope 25, and the support slope 25 can support the receiving member 11 of the connecting assembly 1, so that the receiving member 11 also becomes a step for maintenance personnel to enter and exit the device.

[0047] When the folding ladder is unfolded and placed on the ground, the end of the support frame 22 away from the support slope 25 is not vertically supported on the ground, but is inclinedly placed on the ground, and in order to facilitate the support of the maintenance personnel, the support slope 25 needs to be parallel to the ground. Therefore, the length direction of the support slope 25 and the support frame 22 should be an obtuse angle. When the length direction of the support slope 25 and the support frame 22 is less than 100°, it will be not conducive to the climbing of the maintenance personnel, and when the length direction of the support slope 25 and the support frame 22 is greater than 130°, the folding ladder occupies a larger external space, therefore, the length direction of the support slope 25 and the support frame 22 is 100-130°. When the length direction of the support slope 25 and the support frame 22 is 120°, not only is it convenient for the maintenance personnel to climb, but also the external space occupied by the unfolded folding ladder is smaller.

[0048] The folding ladder further comprises a connecting plate 4, the connecting plate 4 is installed on the side wall of the support frame 22, and the support assembly 3 is rotationally connected with the connecting plate 4.

[0049] The connecting plate 4 can be installed on the side wall of the support frame 22 by welding or bolts, and the support assembly 3 is rotationally connected with the connecting plate 4 through a rotating shaft.

[0050] The support assembly 3 comprises a support column, the support column is rotationally connected with the connecting plate 4, and the side wall of the support column can abut against the side of the support frame 22 close to the external device.

[0051] The side wall of the support column can abut against the side of the support frame 22 close to the external device, so that the side of the support frame 22 close to the external device can limit the rotation angle of the support column when the folding ladder is unfolded, and the stability of the ladder is ensured. The rotational connection between the support column and the connecting plate 4 can be realized by a hinge or other similar mechanical structure, so as to ensure that the support column can adjust the angle and position as needed.

[0052] Referring to Figure 3 , the embodiment of the present application also provides a laser processing equipment comprising the folding ladder in any of the above embodiments.

[0053] The side wall of the laser processing equipment is provided with a side door, the side door is installed on the side wall of the laser processing equipment through a guide rail and a sliding block, and a folding ladder is installed close to the side door. The folding ladder can be pulled out by pulling the side door along the length direction of the guide rail, and the maintenance personnel can enter the laser processing equipment through the folding ladder.

[0054] The laser processing equipment of the embodiments of the present application has the beneficial effects brought by the folding ladders in any of the above embodiments due to the folding ladders in any of the above embodiments, which will not be repeated here.

[0055] The above are only preferred embodiments of the present application, and are not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
