[0002] Scaffolding plays a vital role in the fields of construction and engineering. As a temporary support structure, it is mainly used to provide workers with a safe working platform for various construction, maintenance or decoration operations. The construction of scaffolding ensures the safety of high-altitude operations.

DETAILED DESCRIPTION

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0019] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0020] See also Figures 1 to 8 A telescopic scaffold for culvert construction provided by an embodiment of the present invention comprises a first fixed tube 1 and a second fixed tube 11, wherein a first cavity 12 is defined in the first fixed tube 1, and a second cavity 13 is defined in the second fixed tube 11; a first connecting tube 14 and a second connecting tube 15 are slidably connected in the first cavity 12 and the second cavity 13, respectively; a first vertical pole is fixedly connected to one end of the first connecting tube 14 and the second connecting tube 15, and a second vertical pole is fixedly connected to one end of the first fixed tube 1 and the second fixed tube 11; a first telescopic driving member and a second telescopic driving member are respectively installed in the first cavity 12 and the second cavity 13; a transmission member is installed on one side of the first telescopic driving member and the second telescopic driving member.

[0021] The above scheme is adopted: when in use, when building a scaffold before pouring cover slab concrete during culvert construction, the scaffold is first moved to the designated position, and then, the first telescopic drive member is rotated to drive the first connecting pipe 14 to slide in the first cavity 12. At the same time, this action will drive the second telescopic drive member through the transmission member to rotate the second telescopic drive member, thereby driving the second connecting pipe 15 to slide in the second cavity 13. As the first connecting pipe 14 and the second connecting pipe 15 are extended synchronously, the first vertical pole will also be extended accordingly, thereby increasing the length of the first fixed pipe 1 and the second fixed pipe 11 of the scaffold, effectively solving the problem of long time consumption and low efficiency caused by the tight structure during the construction and disassembly of traditional scaffolding, and through the telescopic adjustment of the first connecting pipe 14 and the second connecting pipe 15, the length of the scaffold can be easily adjusted to adapt to different construction requirements, simplifying the construction and disassembly process, improving work efficiency, and reducing manpower and time consumption.

[0022] It should be noted that the lengths of the first connecting tube 14 and the second connecting tube 15 can be adjusted according to actual needs.

[0023] Furthermore, the first telescopic driving member includes a first rack 2, which is installed in the first cavity 12; a first gear 21 is meshed on one side of the first rack 2, and the first gear 21 is located on one side of the first connecting tube 14; the axial part of the first gear 21 is fixedly connected with a first rotating shaft 22, and the first rotating shaft 22 can extend to the outside of the first fixed tube 1, and the first connecting tube 14 is installed on the first rotating shaft 22 on one side close to the first gear 21.

[0024] The above scheme is adopted: when it is needed to extend the overall length of the first fixed tube 1, the first rotating shaft 22 is rotated to drive the first gear 21 to mesh with the first rack 2. During the meshing process, the rotation of the first gear 21 is converted into linear displacement, thereby pushing the first connecting tube 14 to move in the specified direction inside the first cavity 12. As the first connecting tube 14 is gradually extended, part of the first connecting tube 14 will be separated from the first cavity 12, thereby increasing the overall length of the first fixed tube 1, increasing the flexibility and practicality of the first connecting tube 14, and at the same time, when the first connecting tube 14 moves, it can drive the first upright pole to produce displacement, further expanding the working range of the scaffolding and improving the efficiency of the staff when building the scaffolding.

[0025] It should be noted that: first, when the first gear 21 needs to rotate, the staff can rotate the first rotating shaft 22 to drive the first gear 21 to mesh with the first rack 2, so that the first gear 21 can rotate. Second, if the first gear 21 is no longer needed to rotate, multiple pin holes can be opened on the surface of the first gear 21 and the inner wall of the first connecting tube 14, and a pin can be passed through two aligned pin holes, so as to fix the first gear 21 and stop it from rotating.

[0026] Furthermore, the second telescopic driving member includes a second rack 3, which is installed in the second cavity 13; a second gear 31 is meshed on one side of the second rack 3, and the second gear 31 is located on one side of the second connecting tube 15; the axial part of the second gear 31 is fixedly connected with a second rotating shaft 32, and the second rotating shaft 32 can extend to the outside of the second fixed tube 11, and the second connecting tube 15 is installed on the second rotating shaft 32 on one side close to the second gear 31.

[0027] In the above scheme, when the length of the second fixed tube 11 needs to be extended, the first rotating shaft 22 rotates first, driving the transmission member to rotate. Then, the rotation is transmitted to the second gear 31 through the second rotating shaft 32, causing it to start rotating. During the rotation, the second gear 31 meshes with the second rack 3, and the rotation of the second gear 31 is converted into a linear sliding motion.

[0028] Therefore, the second connecting tube 15 will gradually move in the specified direction inside the second cavity 13. As the movement continues, part of the second connecting tube 15 will gradually extend out of the second cavity 13, thereby increasing the length of the entire second fixed tube 11. This not only enhances the flexibility of the second connecting tube 15, but also improves its practicality.

[0029] At the same time, when the second connecting pipe 15 moves, the second connecting pipe 15 can also push the first upright pole to move, thereby further expanding the working range of the scaffolding, so that the workers can be more efficient and convenient when building the scaffolding.

[0030] It should be noted that: first, the first gear 21 and the second gear 31 rotate synchronously. Second, since the first gear 21 and the second gear 31 rotate synchronously, they respectively push the first connecting tube 14 and the second connecting tube 15 to move synchronously.

[0031] Furthermore, one end of each of the first vertical pole and the second vertical pole is fixedly connected to a scaffolding board support frame 4, a scaffolding board 41 is installed in one of the scaffolding board support frames 4, a third cavity 42 is defined in the scaffolding board 41, a scaffolding connecting plate 43 is slidably connected in the third cavity 42, one side of the scaffolding connecting plate 43 is located in the third cavity 42, and the other side is located in another of the scaffolding board support frames 4, a first connecting plate 44 is installed between the second connecting pipe 15 and the scaffolding connecting plate 43.

[0032] The above solution is adopted: when the length of the scaffolding board 41 needs to be adjusted during use, the first connecting plate 44 is immediately driven by moving the second connecting pipe 15, so that the scaffolding connecting plate 43 slides in the preset third cavity 42. Since one side of the scaffolding connecting plate 43 is fixed in the scaffolding board support frame 4, as it slides, the scaffolding board support frame 4 will also move accordingly, thereby realizing the adjustability of the length of the scaffolding board 41, which not only saves the time of installation and disassembly, but also improves the work efficiency, and also ensures the safety of construction.

[0033] The above scheme has the following effects: First, when the scaffolding board 41 needs to be installed in the scaffolding board support frame 4, if the above-mentioned scheme is not set, at this time, the staff is required to place the scaffolding board 41 in the scaffolding board support frame 4. Due to the influence of the scaffolding height, it will be more laborious for the staff to lift the scaffolding board 41, and it will also be laborious to remove the scaffolding board 41. By setting the above-mentioned scheme, when the scaffolding board 41 is placed in the scaffolding board support frame 4, the scaffolding connecting plate 43 can be retracted to extend the length of the scaffolding board 41, thereby improving the adaptability of the scaffolding board 41 and reducing the number of times the scaffolding board 41 is installed and removed.

[0034] Second, as the scaffolding is extended or retracted, the above solution allows the scaffolding board 41 to adjust its own length according to the length of the scaffolding after extension or retraction.

[0035] It should be noted that: first, one side of the scaffolding board 41 and the scaffolding connecting board 43 are both provided with hooks, and are hooked on the scaffolding board support frame 4 to improve the stability of the scaffolding board 41 and the scaffolding connecting board 43. Second, one side of the first connecting board 44 is fixed to the second connecting pipe 15, and the other side is movably mounted on the scaffolding connecting board 43, so that the scaffolding board 41 and the scaffolding connecting board 43 can be easily disassembled.

[0036] Furthermore, a first slide is fixedly connected to one side of the first fixed tube 1, and a second slide is fixedly connected to one side of the second fixed tube 11; a plurality of sliding support rods 5 are slidably connected between the first slide and the second slide, and a first telescopic rod 51 is fixedly connected between the sliding support rods 5; a second connecting plate 52 is fixedly connected between the first connecting tube 14 and the second connecting tube 15, and a second telescopic rod 53 is fixedly connected between the second connecting plate 52 and one of the sliding support rods 5.

[0037] The above scheme is adopted: when in use, when the first connecting tube 14 and the second connecting tube 15 move, the second connecting plate 52 moves with the movement of the first connecting tube 14, thereby driving the second telescopic rod 53 to extend and retract. When the second telescopic rod 53 is extended to its extreme position, the second telescopic rod 53 pulls the first sliding support rod 5 to slide between the first slideway and the second slideway. This sliding action is further transmitted through the first telescopic rod 51, prompting the second sliding support rod 5 to perform similar movement. This process is carried out in sequence until the first connecting tube 14 reaches the predetermined position, at which time multiple sliding support rods 5 will be evenly distributed on the first fixed tube 1, forming a stable support structure, effectively improving its bearing capacity.

[0038] The above scheme has the following effects: First, if the above-mentioned scheme is not set, when the first connecting tube 14 and the second connecting tube 15 are extended, the uneven distribution of the sliding support rod 5 often leads to insufficient bearing capacity in some parts. By setting the above-mentioned scheme, the sliding support rod 5 will adjust its position according to the change of its extended length, ensuring that a stable supporting force is always maintained between the first fixed tube 1 and the second fixed tube 11.

[0039] Second, if the above scheme is not set up, when the extended part of the scaffolding connecting plate 43 needs to place materials, the gravity generated by the materials will be transmitted to the second connecting tube 15. If the second telescopic rod 53 is not set between the second connecting tube 15 and the first connecting tube 14, the extended part will be borne by the second connecting plate 52 alone. The second connecting plate 52 may be deformed under the action of gravity, resulting in reduced stability of the entire structure. By setting the above scheme, since the two ends of the second telescopic rod 53 are respectively fixed on the second connecting plate 52 and the sliding support rod 5, the first telescopic rod 51 serves as an additional support point, which can help disperse the gravity generated by the materials, thereby enhancing the stability of the entire structure.

[0040] Third, through the above solution, the first telescopic rod 51 and the second telescopic rod 53 can be allowed to be telescopic to a certain extent to adapt to materials of different weights and sizes, thereby increasing the flexibility of the structure.

[0041] Furthermore, the transmission member includes a first sprocket 6 and a second sprocket 61, the first sprocket 6 is fixedly connected to the outer surface of the first rotating shaft 22, the first sprocket 6 is located on the outside of the first fixed tube 1, the second sprocket 61 is fixedly connected to the outer surface of the second rotating shaft 32, the second sprocket 61 is located on the outside of the second fixed tube 11, and chains 62 are installed on the outer surfaces of the first sprocket 6 and the second sprocket 61.

[0042] The above scheme is adopted: when the second rotating shaft 32 needs to rotate, the first rotating shaft 22 is first driven to rotate by the power source, and this rotation is then transmitted to the first sprocket 6 directly connected thereto, so that it rotates synchronously. Subsequently, the chain 62 on the first sprocket 6 starts to move, and the other end of the chain 62 is connected to the second sprocket 61, so the movement of the chain 62 drives the rotation of the second sprocket 61. Finally, the rotation of the second sprocket 61 causes the second rotating shaft 32 connected thereto to rotate accordingly.

[0043] Furthermore, two symmetrical grooves are provided in the first fixed tube 1 and the second fixed tube 11 , and a plurality of rotating rods 8 are installed in the grooves. The outer surfaces of the rotating rods 8 are fixedly connected with pulleys 81 .

[0044] The above scheme is adopted: when in use, when the first connecting tube 14 moves in the first cavity 12, the pulley 81 in the groove will contact the surface of the first connecting tube 14. If the first connecting tube 14 moves, it will drive the pulley 81 to rotate on the outer surface of the rotating rod 8, so that the pulley 81 can drive the first connecting tube 14, provide mutual transmission, and further improve the smoothness of the movement of the first connecting tube 14.

[0045] It should be noted that: a pulley 81 is also provided in the second cavity 13, and the working mode and the effect produced are the same as above.

[0046] Furthermore, one end of each of the first vertical pole and the second vertical pole is fixedly connected with a supporting foot 9 .

[0047] With the above solution, when the first and second vertical poles are moved to the required positions, the support feet 9 on the first and second vertical poles will be displaced synchronously to ensure that they are always in contact with the ground during the movement. When the first and second vertical poles are moved into place, the support feet 9 will be fixed on the ground, thereby providing a stable support force for the entire scaffolding, significantly improving the stability and safety of the scaffolding.

[0048] It should be noted that: first, a ball bearing can be installed on the support foot 9 to improve the smoothness of the movement of the first and second upright poles. Second, a pin hole can be opened on the support foot 9, and the support foot 9 can be connected to the ground by inserting the pin hole to fix it.

[0049] Different from the first embodiment, the sliding support rod 5 can also be driven in the following manner, see Figures 9 and 10 A third connecting plate 91 is rotatably connected between the first rotating shaft 22 and the second rotating shaft 32 , and a connecting frame 92 is fixedly connected to the third connecting plate 91 , and one end of the connecting frame 92 is respectively inserted into a plurality of sliding support rods 5 .

[0050] The above solution is adopted: when the total length of the scaffold needs to be increased during use, the staff pushes the third connecting plate 91. This thrust is transmitted to the first gear 21 through the first rotating shaft 22, so that the first gear 21 rotates, and then drives the corresponding part of the scaffold to unfold, thereby expanding its overall length. At the same time, as the third connecting plate 91 moves, the third connecting plate 91 will link the multiple sliding support rods 5 through the connecting frame 92, so that the multiple sliding support rods 5 can move synchronously in the specified direction and be distributed on the first fixed pipe 1. At this time, the multiple sliding support rods 5 will provide sufficient support force for the scaffolding board 41.

[0051] It should be noted that: first, since the third connecting plate 91 is connected to the first rotating shaft 22 and the second rotating shaft 32, the third connecting plate 91 will also push the second rotating shaft 32 when moving, further improving the stability of the first rotating shaft 22 and the second rotating shaft 32 when moving. Second, since the first rotating shaft 22 itself can rotate, the first rotating shaft 22 can also be driven to drive the third connecting plate 91 to move synchronously. Third, the length of the first slideway and the second slideway can be adjusted according to actual needs. Fourth, when the sliding support rod 5 continues to move in the specified direction, one of the sliding support rods 5 will be separated from the first slideway and the second slideway and reach between the first connecting tube 14 and the second connecting tube 15. At this time, the sliding support rod 5 is in a suspended state, and then the staff can rotate the two top rods in the sliding support rod 5 to extend the two top rods upward and downward respectively until they are in contact with the first connecting tube 14 and the second connecting tube 15 respectively, further providing support force for the first connecting tube 14 and the second connecting tube 15. Fifth, since the two push rods are both threadedly connected to the sliding support rod 5, if the sliding support rod 5 needs to move in the reverse direction, the above steps can be repeated.

[0052] Working principle of the present invention: The preparatory work before pouring the cover slab concrete for culvert construction involves the construction of scaffolding. First, the scaffolding needs to be moved to the predetermined construction location. Then, the first telescopic drive member is started to rotate. This rotational action will cause the first connecting tube 14 to move linearly inside the first cavity 12. At the same time, due to the connection of the transmission member, this action will also cause the second telescopic drive member to rotate. As the second telescopic drive member rotates, the second connecting tube 15 will perform corresponding linear movement inside the second cavity 13. As the first connecting tube 14 and the second connecting tube 15 extend outward synchronously, the first upright portion of the scaffolding will also extend outward accordingly, thereby achieving the effect of increasing the total length of the first fixed tube 1 and the second fixed tube 11.
