Description

Technical Field

[0001] This utility model relates to indoor construction tools, and in particular to an elevated climbing frame. Background Technology

[0002] Aerial work platforms are a type of indoor construction tool, commonly used for ceiling work, such as installing suspended ceilings, lighting fixtures, and plastering. Existing aerial work platforms typically consist of poles and multiple support plates welded together, making them inconvenient to move or access indoors. Therefore, detachable aerial work platforms are also available, where the poles and support plates can be disassembled for easier movement and access indoors. They can be reassembled only when needed, although this process is relatively more complex. Utility Model Content

[0003] This application provides a climbing frame that uses two side frames and a connecting frame to keep the two side frames relatively fixed by folding them together and using a support plate. This allows for easy movement and access to indoor spaces, and also enables quick and simple assembly when needed.

[0004] This application provides an elevated access platform, comprising:

[0005] Two side frames, each side frame consisting of two vertical rods and multiple horizontal rods fixed between the two vertical rods; the multiple horizontal rods of the two side frames correspond one-to-one, forming multiple installation groups;

[0006] The connecting frame includes: a first frame and a second frame hinged to the first frame about a vertical axis; the first frame is also hinged to a vertical rod on a first side of a side frame, and the second frame is also hinged to a vertical rod on a first side of another side frame;

[0007] Multiple support plates are detachably connected to different mounting groups; their width is less than the length of the horizontal bar and they are staggered along the axis of the horizontal bar; with the support plates installed in the mounting group, the two side frames remain relatively fixed.

[0008] In some embodiments, the support plate has connecting pieces at both wide positions, and the bottom of the connecting pieces has mounting recesses for mates with horizontal bars.

[0009] In some embodiments, limit bolts are provided between the two width positions of the support plate and the corresponding horizontal bar. The limit bolts are used to restrict the disassembly and movement of the support plate relative to the horizontal bar.

[0010] In some embodiments, the number of support plates is two.

[0011] In some embodiments, one of the wider inner sides of the support plate has two first mounting portions, which are detachably connected to the top of the vertical rods; the other wider side has two notches that mate with the two vertical rods.

[0012] In some embodiments, the top of the vertical pole has a second mounting portion for connection to the bottom end of the vertical pole of another climbing frame.

[0013] In some embodiments, the bottom end of the vertical rod is fixedly connected to a caster wheel with a foot brake.

[0014] In summary, this application discloses a climbing frame, comprising two side frames, a connecting frame, and multiple support plates. When the climbing frame is not in use, the support plates are detached from the mounting assembly, and the two side frames switch from being relatively fixed to being relatively movable, reducing the distance between the two side frames. The hinge joint of the first and second frame bodies enters between the two side frames, folding up the two side frames and the connecting frame. When using the climbing frame, the distance between the two side frames is increased. After reaching the designed installation position, the support plates are installed on the mounting assembly, keeping the two side frames relatively fixed. The advantages include: simple structure, convenient installation and disassembly, and the ability to be folded up when not in use, reducing space occupation and facilitating movement and access to indoor spaces.

[0030] Please see Figure 1 A climbing frame includes two side frames 1, a connecting frame 2, and multiple support plates 3.

[0031] Please see Figure 1 and Figure 2 The two side frames 1 have the same structure, including two vertical rods 1a and multiple horizontal rods 1b. The multiple horizontal rods 1b are fixedly connected between the two vertical rods 1a, and the installation positions of the multiple horizontal rods 1b in the two side frames 1 are the same, so that the multiple horizontal rods 1b of the two side frames 1 correspond one-to-one, and the corresponding two horizontal rods 1b form a set of installation groups.

[0032] The connecting frame 2 includes a first frame 2a and a second frame 2b. The second frame 2b is hinged to the first frame 2a about a vertical axis, and a connecting pin can be used at the hinge position. The first frame 2a is also hinged to a vertical rod 1a on the first side of one side frame 1, and the second frame 2b is also hinged to a vertical rod 1a on the first side of the other side frame 1. More specifically, both vertical rods 1a have two hinged sections with smaller diameters, and both the first frame 2a and the second frame 2b have connecting sleeves for connecting to the hinged sections.

[0033] In this way, the two side frames 1 can move relative to each other. When the distance between the two side frames 1 changes, the connecting frame 2 swings accordingly, changing the angle between the first frame 2a and the corresponding connecting frame 2, and the angle between the second frame 2b and the corresponding connecting frame 2.

[0034] Please see Figure 1 and Figure 3 Multiple support plates 3 can be detachably connected to different mounting groups. That is, a maximum of one support plate 3 can be installed on a mounting group. The number of support plates 3 can be the same as the number of mounting groups or less than the number of mounting groups.

[0035] The width of the support plate 3 is less than the length of the horizontal bar 1b. That is, during the design, the support plate 3 can be adjusted along the axis of the horizontal bar 1b when it is installed into the mounting assembly to determine the required installation position, so that multiple support plates 3 are staggered in the axial direction of the horizontal bar 1b.

[0036] With the support plate 3 installed in the mounting assembly, the two side frames 1 remain relatively fixed.

[0037] In some embodiments, fasteners can be used to connect the support plate 3 and the side frame 1.

[0038] Please see Figure 3 and Figure 4 In some embodiments, the support plate 3 has connecting pieces 3a at both wide positions, and the bottom of the connecting pieces 3a has mounting recesses 3a1 that mate with the horizontal rod 1b. When the support plate 3 remains horizontal and moves downward, the mounting recesses 3a1 can be fitted into the horizontal rod 1b.

[0039] Compared to using fasteners, this method makes the installation and disassembly of the support plate 3 and the horizontal bar 1b much easier. At the same time, the support plate 3 and the horizontal bar 1b are more stable and secure, less prone to relative slippage, and multiple support plates 3 can be stably maintained offset along the axis of the horizontal bar 1b.

[0040] Please see Figure 4 In some embodiments, based on the above-described embodiment where "the support plate 3 has connecting pieces 3a at both width positions," limit bolts 4 are provided between the support plate 3 at both width positions and the corresponding horizontal rod 1b. The limit bolts 4 are used to restrict the disassembly and movement of the support plate 3 relative to the horizontal rod 1b. More specifically, the limit bolt 4 may be threaded to one of the support plate 3 and the horizontal rod 1b, while the other has an insertion hole for the limit bolt 4 to enter.

[0041] After the mounting notch 3a1 is fitted onto the horizontal rod 1b, rotate the limiting bolt 4 to allow it to enter the insertion hole, thus restricting the disassembly between the support plate 3 and the horizontal rod 1b and limiting the relative sliding between them, making the support plate 3 and the horizontal rod 1b more stable and secure.

[0042] When the climbing frame is not in use, the support plate 3 is removed from the installation assembly, and the two side frames 1 are switched from being relatively fixed to being relatively movable, reducing the distance between the two side frames 1. The hinge joints of the first frame 2a and the second frame 2b are then inserted between the two side frames 1, and the two side frames 1 and the connecting frame 2 are folded together. When using the leveling frame, the distance between the two side frames 1 is increased until the designed installation position is reached, and then the support plate 3 is installed on the installation assembly. More specifically, it can be designed such that the designed installation position is reached when the included angle between the first frame 2a and the second frame 2b is 180 degrees.

[0043] In some embodiments, the number of support plates 3 is two.

[0044] The design of two support plates 3 makes it easier to reach the required height for indoor roof construction and also makes it easier to climb and reach the same height on the two support plates 3.

[0045] Please see Figure 1 and Figure 7 In some embodiments, based on the embodiment where "the number of support plates 3 is two," one of the support plates 3 has two first mounting portions 3b on its inner wide side, and the other wide side has two notches 3c that mate with two vertical rods 1a. The first mounting portions 3b are detachably connected to the top of the vertical rods 1a. More specifically, the first mounting portion 3b can be a plug-in post, and the top of the vertical rod 1a has a plug-in hole for inserting the plug-in post.

[0046] In this way, when the climbing frame is not in use, the support plate 3 is removed from the mounting assembly, and the two side frames 1 and the connecting frame 2 are folded up. One support plate 3 is turned from horizontal to vertical, with the two first mounting parts 3b on top. One first mounting part 3b is connected to the vertical rod 1a on the first side of one of the side frames 1, and the other first mounting part 3b is connected to the numerical rod on the first side of the other side frame 1. The support plate 3 is then installed on the two vertical rods 1a. The other support plate 3 is installed on the numerical rod on the second side of the two side frames 1 in the same way.

[0047] Please see Figure 5 In some embodiments, the top end of the vertical rod 1a has a second mounting portion 1a1, which is used for connecting the bottom end of another vertical rod 1a of the climbing frame. More specifically, the second mounting portion 1a1 can be a plug-in post with a diameter smaller than that of the vertical rod 1a, and the bottom end of the vertical rod 1a has a plug-in hole for the plug-in post to enter. The two vertical rods 1a are then connected by a horizontal connecting pin.

[0048] In this way, the two climbing frames can be stacked together. Combining the two embodiments of "the top of the vertical rod 1a has a second mounting part 1a1" and "the support plate 3 has two first mounting parts 3b", when the second mounting part 1a1 is a plug-in post, the first mounting part 3b can be designed as a plug-in hole.

[0049] Please see Figure 6 In some embodiments, the bottom end of the vertical rod 1a is fixedly connected to a caster wheel 5 with a foot brake.

[0050] This makes it easier to move the climbing frame and to fold up the two side frames 1 and the connecting frame 2.
