[0025] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0026] like Figure 1 and Figure 2 As shown, a climbing device for power transmission and transformation construction in one embodiment of the utility model includes a ladder cap 11, which is a pair. A ladder frame 12 is welded on the ladder cap 11. A first hinge 13 is rotatably connected in the middle of the pair of ladder caps 11. The ladder caps 11 can be folded by rotating the first hinge 13, and can be folded when not in use to reduce the floor space.

[0027] like Figures 1 to 4 As shown, a support plate 2 is installed between a pair of ladder frames 12, and the support plate 2 is rotatably connected to the side walls of a pair of ladder frames 12. A third hinge 22 is installed at the symmetrical center line position of the support plate 2, and second hinges 21 are respectively installed on the opposite side walls of the support plate 2. The second hinges 21 form a pair, and the pair of second hinges 21 are symmetrically installed on the side walls of the support plate 2.

[0028] Specifically, the second hinge 21 installed on the support plate 2 is rotatably connected to the side wall of the ladder frame 12, and the support plate 2 is rotatably connected to the ladder frame 12 through the second hinge 21. At the same time, the support plate 2 can also be folded through the third hinge 22. When the ladder frame 12 is opened, the support plate 2 installed between a pair of ladder frames 12 is unfolded.

[0029] In order to ensure that the unfolded support plate 2 is stable, a third opening 201 is provided on the support plate 2, and a first opening 1201 and a second opening 1202 are provided on the ladder frame 12. The first opening 1201 is provided on the end face of the ladder frame 12, and the first opening 1201 passes through the opposite end face of the ladder frame 12. The second opening 1202 is provided on the side wall of the ladder frame 12 and passes through the inner wall of the ladder frame 12. The first opening 1201 is communicated with the second opening 1202.

[0030] A pair of slide bars 3 are slidably connected in the first opening 1201. A limit rod 31 is welded on the side wall of the slide bar 3. The limit rod 31 is flush with an end surface of the slide bar 3 that slides in the first opening 1201. The limit rod 31 passes through the second opening 1202 on the ladder frame 12 and slides on the upper surface of the support plate 2.

[0031] When the pair of slide bars 3 are butted against each other, the thickness of the limiting rods 31 on the pair of slide bars 3 is smaller than the width of the third opening 201 .

[0032] Specifically, after the pair of ladder caps 11 are opened, the support plate 2 is unfolded accordingly. During the unfolding process of the support plate 2, the limit rod 31 on the slide bar 3 penetrates the third opening 201 on the support plate 2, so the limit rod 31 will not restrict the unfolding of the support plate 2. After the support plate 2 is unfolded, the pair of slide bars 3 slidably connected in the first opening 1201 are pulled out. During the process of pulling out the slide bars 3, the limit rod 31 on the slide bars 3 moves in the second opening 1202, and the limit rod 31 will press against the upper surface of the support plate 2, so that the support plate 2 cannot be turned over. The support plate 2 increases the contact area between the stepladder and the ground, so that the stepladder can also be used on soft ground.

[0033] Because the pair of ladder frames 12 are held by the two ends of the support plate 2, the angle of the pair of ladder frames 12 when unfolded can be limited, thereby increasing the safety of the stepladder when in use.

[0034] Furthermore, a pad 36 is welded on the lower panel of the slide bar 3, the area of ​​the pad 36 is equal to the area of ​​the slide bar 3 exposed from the first opening 1201, and the thickness of the pad 36 is equal to the thickness of the lower wall of the first opening 1201. When the slide bar 3 is pulled out, when the limit rod 31 abuts against the side wall of the second hinge 21, the distances of the pair of limit rods 31 pulled out from the first opening 1201 are equal, and the pad 36 is symmetrical with respect to the ladder, which can make the ladder more stable.

[0035] When the side wall of the pad 36 abuts against the ladder frame 12, the end faces of the pair of slide bars 3 are in contact, and the limit rod 31 on the slide bar 3 is just at the position of the third opening 201. When the slide bar 3 is pulled out from the third opening 201, the pad 36 on the slide bar 3 and the lower end face of the ladder frame 12 can abut against the ground at the same time. The pad 36 is provided with an anti-skid layer, which can increase the friction with the ground and increase the stability of the stepladder in contact with the ground.

[0036] After use, push the slide bar 3 into the first opening 1201. When the side wall of the slide bar 3 is against the front end surface of the ladder frame 12, the limit rod 31 on the slide bar 3 can be exactly at the position of the third opening 201 on the support plate 2. At this time, the ladder frame 12 is folded, and the limit rod 31 will pass through the third opening 201, and will no longer restrict the flipping state of the support plate 2. The support plate 2 can be folded accordingly, reducing the footprint.

[0037] like Figure 5 and Figure 6 As shown, a connecting column 32 is welded on the front end surface of the slide bar 3, a through hole is formed on the connecting column 32, and a support column 33 is slidably connected in the through hole on the connecting column 32. A universal wheel 35 is installed on the lower end surface of the support column 33, and a spring sheet 34 is welded on the upper end surface of the support column 33, and one end surface of the spring sheet 34 away from the support column 33 is welded on the slide bar 3.

[0038] Specifically, when a worker presses down on the ladder, the elastic deformation of the spring piece 34 drives the support column 33 to slide upward, so that the universal wheel 35 is separated from the ground. At this time, the pad 36 and the ladder frame 12 are in contact with the ground, and the worker can climb onto the ladder to perform the operation. After the operation is completed, the worker steps down from the ladder and steps on one end of the spring piece 34 welded to the support column 33. The spring piece 34 is elastically deformed, causing the support column 33 to slide downward, so that the universal wheel 35 is in contact with the ground, and the ladder is lifted. When the worker transfers the ladder, he can push the ladder to move, without having to carry the ladder, which can save more effort.

[0039] Furthermore, the spring sheet 34 can be set as an elastic steel plate that can bear the weight of the ladder itself. When the worker steps on the ladder, the spring sheet 34 is deformed, and the ladder frame 12 is in contact with the ground. When the worker gets off the ladder, the spring sheet 34 can just support the weight of the ladder, so that the bottom surface of the ladder frame 12 is separated from the ground, and the universal wheel 35 is in contact with the ground, so that the ladder can be easily moved.

[0040] When used under normal working conditions, the pair of ladder frames 12 are opened and the support plate 2 is unfolded. The worker can climb up the ladder to work, and the angle of the ladder frame 12 held by the support plate 2 is fixed, so that the ladder frame 12 will not slip between the ladder frame 12 and the ground, resulting in the ladder frame 12 being unfolded at an excessive angle and affecting stability.

[0041] When used on soft ground, first open a pair of ladder frames 12 and unfold the support plate 2, then pull the sliding rod 3 slidably connected in the first opening 1201 out of the first opening 1201, and the limiting rod 31 on the sliding rod 3 can resist the upper panel of the support plate 2, so that the support plate 2 remains horizontal. In this way, the contact area between the herringbone ladder and the ground can be increased, and the pressure per unit area of ​​the ground can be reduced. The herringbone ladder will not be skewed, and the stability of the herringbone ladder when in use can be guaranteed.

[0042] After use, the slide bar 3 is pushed into the first opening 1201. When the side wall of the limiting rod 31 abuts against the ladder frame 12, the limiting rod 31 on the slide bar 3 is exactly at the position where the third opening 201 is opened on the support plate 2, and the ladder frame 12 can be smoothly closed. The limiting rod 31 welded on the lower plate of the slide bar 3 can not only increase the contact area between the ladder and the ground, but also limit the length of the slide bar 3 pushed into the first opening 1201, so as to reduce the floor space of the ladder and facilitate storage.

[0043] During continuous operation, the ladder can be pushed and moved by the moving assembly installed on the slide bar 3, and the staff does not need to move the ladder, which is more labor-saving to use.

[0044] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
