[0042] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] Combine the following Figures 1 to 10 , describing an embodiment of the present invention.

[0044] According to an embodiment of the present invention, there is provided a scaffold, comprising:

[0045] The support panel 1 comprises a main panel 3 and an extension panel 4 connected to each other, wherein the extension panel 4 has a first state of being extended or retracted along the length direction of the main panel 3, and a second state of being fixed relative to the main panel 3;

[0046] A driving assembly 7, connected to the extension panel 4, and adapted to drive the extension panel 4 to switch between a first state and a second state;

[0047] The support frame 2 is hingedly connected to the support panel 1 and has a supporting position opened to support the support panel 1 and a storage position retracted to be disposed close to the support panel 1 .

[0048] The scaffolding provided in this embodiment adjusts the relative positions of the extension panel 4 and the main panel 3 through the driving component 7, so as to adjust the supporting area of ​​the supporting panel 1 according to actual needs, which is conducive to improving the flexibility of adjusting the supporting area of ​​the scaffolding.

[0049] Specifically, the plane where the main panel 3 is located is parallel to the plane where the extension panel 4 is located. The driving component 7 is arranged below the main panel 3 and connected to the extension panel 4 to drive the extension panel 4 to move along the length direction of the main panel 3, thereby flexibly adjusting the supporting area of ​​the supporting panel 1.

[0050] At least two support frames 2 are provided. When the support frames 2 are in the supporting position, the plane where the support frames 2 are located is perpendicular to the plane where the support panel 1 is located. At this time, the plane where the support panel 1 is located is parallel to the horizontal direction. The support frames 2 can be hingedly connected to the main panel 3, or hingedly connected to the extension panel 4 and move with the extension panel 4. By rotating the support frames 2, the support frames 2 can be switched between the supporting position and the storage position. When the support frames 2 are in the storage position, the support frames 2 are close to the bottom of the support panel 1. Retracting the extension panel 4 and adjusting the support frames 2 to the storage position is conducive to the turnover and transportation of the scaffolding.

[0051] In some embodiments, in combination Figures 1 to 10 As shown, one end of the extension panel 4 away from the main panel 3 is fixedly connected to the pallet 11; the driving assembly 7 includes a driving motor 18 fixedly connected to the bottom of the main panel 3, and the driving motor 18 is transmission-connected to the pallet 11 to drive the pallet 11 to move along the length direction of the main panel 3.

[0052] Specifically, the driving motor 18 drives the supporting plate 11 to move along the length direction of the main panel 3 , thereby driving the extension panel 4 to move along the length direction of the main panel 3 , thereby changing the supporting area of ​​the supporting panel 1 .

[0053] In some embodiments, in combination Figures 1 to 10 As shown, two extension panels 4 and two support plates 11 are provided, and are respectively arranged at the two ends of the main panel 3 along the length direction. The driving component 7 also includes a transmission component 5 connected between the driving motor 18 and the two support plates 11. The driving motor 18 drives the two support plates 11 to move relative to or away from each other at the same time through the transmission component 5.

[0054] In the scaffolding provided in this embodiment, the driving motor 18 drives the two support plates 11 to move relative to or away from each other through the transmission assembly 5 at the same time, which is beneficial to improving the adjustment efficiency of the supporting area of ​​the supporting panel 1.

[0055] Specifically, the driving motor 18 is connected to the two support plates 11 through the transmission assembly 5 at the same time, so as to be suitable for driving the two support plates 11 to move relative to or away from each other at the same time.

[0056] In some embodiments, in combination Figures 1 to 10 As shown, the driving assembly 7 also includes a U-shaped bottom plate 6 fixedly connected to the bottom of the main panel 3, and the opening of the U-shaped bottom plate 6 faces the main panel 3, the web of the U-shaped bottom plate 6 extends along the width direction of the main panel 3 to form a limiting plate 31, and the transmission assembly 5 is arranged between the limiting plate 31 and the main panel 3.

[0057] The scaffolding provided in this embodiment limits the side of the transmission assembly 5 away from the main panel 3 by the limiting plate 31, which is beneficial to improve the stability of the transmission assembly 5 during the transmission process, thereby improving the reliability of the scaffolding.

[0058] Specifically, the drive motor 18 is fixedly connected to the side of the web of the U-shaped bottom plate 6 facing the main panel 3, and the output end of the drive motor 18 performs a rotational motion. The transmission assembly 5 includes a threaded rod 19, and the threaded rod 19 and the output end of the drive motor 18 are coaxially fixedly connected through a coupling, and the axis of the threaded rod 19 is parallel to the length direction of the main panel 3.

Along the length direction of the main panel 3, the area of ​​the support plate 11 corresponding to the U-shaped bottom plate 6 is penetrated to form a clearance opening 30 to prevent the support plate 11 from colliding with the U-shaped bottom plate 6 during the movement of the support plate 11 along the length direction of the main panel 3.

[0060] The transmission assembly 5 also includes a gear 21 and a second tooth plate 23. The gear 21 is rotatably connected to the bottom of the main panel 3, and the axis of the gear 21 is perpendicular to the plane where the main panel 3 is located. The plane where the second tooth plate 23 is located is parallel to the plane where the two side plates of the U-shaped push plate 20 are located. There are two second tooth plates 23, which are respectively arranged on the side of the two side plates of the U-shaped push plate 20 that are away from each other, and the tooth grooves of the second tooth plate 23 are arranged toward the U-shaped push plate 20. The side of the two side plates of the U-shaped push plate 20 that are away from each other is provided with tooth grooves corresponding to the second tooth plate 23. There are at least two gears 21, which are meshed with the tooth grooves on the second tooth plate 23 and the U-shaped push plate 20. At least one gear 21 is respectively arranged between each set of the second tooth plate 23 and the side plate of the U-shaped push plate 20, and the side plate of the U-shaped push plate 20 and the second tooth plate 23 are moved relative to or away from each other at the same time through the gears 21.

[0061] The two side plates of the U-shaped push plate 20 that face away from each other can be integrally formed with a tooth groove that meshes with the gear 21. At this time, the U-shaped push plate 20 and the second tooth plate 23 are slidably connected between the limit plate 31 and the main panel 3; the two side plates of the U-shaped push plate 20 that face away from each other can also be fixedly connected to the first tooth plate 22, and the side of the first tooth plate 22 that faces away from the U-shaped push plate 20 is provided with a tooth groove that meshes with the gear 21. At this time, the U-shaped push plate 20, the first tooth plate 22 and the second tooth plate 23 are slidably connected between the limit plate 31 and the main panel 3.

[0062] In some embodiments, in combination Figures 1 to 10As shown, the support frame 2 is hingedly connected to the support plate 11, a first pin hole 34 is provided on the support plate 11, a pin plate 16 is fixedly connected to the side of the support frame 2 facing away from the main panel 3, a second pin hole 17 is provided on the pin plate 16 corresponding to the first pin hole 34, when the support frame 2 is in the supporting position, a pin rod 14 is passed through the first pin hole 34 and the second pin hole 17, and the pin rod 14 is suitable for preventing the support frame 2 from rotating relative to the support plate 11.

[0063] In the scaffolding provided in this embodiment, when the support frame 2 is in the supporting position, the pin rod 14 is inserted into the first pin hole 34 and the second pin hole 17 to prevent the support frame 2 and the support plate 11 from accidentally rotating, which is beneficial to improving the safety of the scaffolding.

[0064] Specifically, each support plate 11 is provided with at least one first pin hole 34. When the support frame 2 is in the supporting position, along the length direction of the main panel 3, the projection of the pin-connecting plate 16 partially overlaps with the projection of the support plate 11. The pin-connecting plate 16 is provided with a second pin hole 17 at the position corresponding to the first pin hole 34. The pin rod 14 is inserted into the first pin hole 34 and the second pin hole 17 to lock the relative position of the support frame 2 and the support plate 11 to prevent the support frame 2 and the support plate 11 from accidentally rotating.

[0065] In some embodiments, in combination Figures 1 to 10 As shown, a spring 15 is sleeved on the pin rod 14, and the spring 15 is located on the side of the support plate 11 close to the main panel 3, and one end of the spring 15 is fixedly connected to the support plate 11, and the other end is fixedly connected to the pin rod 14. When the pin rod 14 is inserted into the first pin hole 34 and the second pin hole 17, the spring 15 is in a naturally extended state.

[0066] In the scaffolding provided in this embodiment, the pin rod 14 is connected to the support plate 11 by a spring 15, which is beneficial to prevent the pin rod 14 from falling off the scaffolding, and when the support frame 2 is in the supporting position, it can also prevent the pin rod 14 from being disengaged from the position of the first pin hole 34 and the second pin hole 17 under natural use, thereby preventing the support frame 2 from accidentally rotating.

[0067] Specifically, one end of the spring 15 is fixedly connected to the side of the support plate 11 away from the pin-connecting plate 16, and the other end is fixedly connected to the area of ​​the pin rod 14 located on the side of the support plate 11 away from the pin-connecting plate 16. When the support frame 2 switches from the storage position to the support position, the pin rod 14 is pulled in the direction close to the main panel 3. At this time, the spring 15 is in a stretched state, and when the support frame 2 rotates to the point where the axis of the second pin hole 17 and the first pin hole 34 coincide, the pin rod 14 is released. Under the elastic action of the spring 15, the pin rod 14 moves to the position of pinning the first pin hole 34 and the second pin hole 17. When the support frame 2 is switched from the supporting position to the storage position, the pin rod 14 is pulled in the direction close to the main panel 3. At this time, the spring 15 is in a stretched state. When the pin rod 14 is disengaged from the second pin hole 17, the support frame 2 is rotated to make it disengage from the supporting position. After releasing the pin rod 14, under the action of the spring 15, the pin rod 14 is located in the first pin hole 34, which can prevent the pin rod 14 from falling off the scaffolding, which is beneficial to improving the convenience of switching the support frame 2 between the supporting position and the storage position.

[0068] In some embodiments, in combination Figures 1 to 10 As shown, the extension panel 4 includes a plurality of plug boards 9 arranged in parallel and at intervals along the width direction of the main panel 3. The main panel 3 is provided with slots 12 corresponding to the plug boards 9. The slots 12 extend along the length direction of the main panel 3, and the plug boards 9 are slidably arranged in the slots 12.

[0069] Specifically, there are two extension panels 4, which are respectively arranged at both ends of the main panel 3 along its length direction. Preferably, the slots 12 corresponding to the plug boards 9 at both ends of the main panel 3 are arranged on the main panel 3 in sequence and staggered.

[0070] In some embodiments, in combination Figures 1 to 10 As shown, at least one end face of the plug plate 9 along the width direction of the main panel 3 is fixedly connected with a slider 10, and the slot 12 is provided with a limiting groove 13 corresponding to the slider 10, and the limiting groove 13 extends along the length direction of the main panel 3, and the slider 10 is slidably set in the limiting groove 13.

[0071] The scaffolding provided in this embodiment is provided with a slider 10 on the plug board 9 and the slider 10 is slidably disposed in the limiting groove 13 so as to improve the sliding stability of the plug board 9 in the slot 12 .

[0072] Specifically, combined Figure 7 As shown, the limiting groove 13 is suitable for limiting the slider 10 in a direction perpendicular to the plane where the main panel 3 is located, so as to improve the sliding stability of the plug board 9 in the limiting groove 13. The limiting groove 13 also limits the moving distance of the slider 10 to prevent the plug board 9 from excessively extending out of the slot 12.

[0073] In some embodiments, in combination Figures 1 to 10As shown, a local area of ​​the upper end surface of the plug plate 9 is recessed to form a gasket groove 24 , and the scaffolding further includes a gasket plate 25 , which is detachably arranged in the gasket groove 24 where the main panel 3 is exposed.

[0074] The scaffolding provided in this embodiment is beneficial to improving the supporting effect of the extended panel 4 by arranging a pad 25 on the plugging plate 9 to cover the gaps between the plurality of plugging plates 9 .

[0075] Specifically, there are multiple pads 25, so that according to the distance that the plug board 9 extends out of the slot 12, a suitable number of pads 25 can be selected and installed in the area where the pad groove 24 exposes the main panel 3, thereby covering the gaps between the multiple plug boards 9, thereby providing reliable protection for the safe work of the workers on the scaffolding.

[0076] In some embodiments, in combination Figures 1 to 10 As shown, the end of the plug plate 9 away from the main panel 3 is fixedly connected with a fixing rod 8, and the end surface of the pad 25 used to abut against the fixing rod 8 is provided with a positioning rod 26, and the fixing rod 8 is provided with a first positioning hole 27 corresponding to the positioning rod 26;

[0077] And / or, a positioning rod 26 is provided on the end surface of the pad 25 that is in contact with the main panel 3 , and a second positioning hole 29 is provided on the end surface of the main panel 3 along its length direction corresponding to the positioning rod 26 .

[0078] The scaffolding provided in this embodiment improves the installation stability of the pad 25 on the plug plate 9 by opening a first positioning hole 27 opposite to the positioning rod 26 on the fixing rod 8 and / or opening a second positioning hole 29 corresponding to the positioning rod 26 on the main panel 3, which is beneficial to improving the stability of the scaffolding in use.

[0079] Specifically, when installing the pad 25, the driving motor 18 drives the plugging plate 9 to extend out of the slot 12, and then the pad 25 is placed in the pad groove 24, and the positioning rod 26 is aligned with the first positioning hole 27 and / or the second positioning hole 29, and the driving motor 18 is reversed to drive the fixing rod 8 to move a certain distance toward the main panel 3 until the positioning rod 26 is inserted into the first positioning hole 27 and / or the second positioning hole 29, thereby fixing the relative position of the pad 25 and the plugging plate 9. When it is necessary to remove the pad 25, the driving motor 18 drives the plugging plate 9 to move in the direction of extending out of the slot 12 until the positioning rod 26 is disengaged from the first positioning hole 27 and / or the second positioning hole 29, so as to facilitate the removal of the pad 25, and the driving motor 18 is reversed to facilitate the retraction of the plugging plate 9.

[0080] In addition, an assembly block 28 is fixedly connected to the bottom of the main panel 3, the gear 21 is rotatably connected to the assembly block 28, the U-shaped push plate 20 and the second tooth plate 23 are slidably connected between the assembly block 28 and the limit plate 31, at this time, the U-shaped push plate 20 and the second tooth plate 23 have a certain spacing from the bottom of the main panel 3, after the pad 25 is removed, it can be placed in the gap between the U-shaped push plate 20 and the second tooth plate 23 and the bottom of the main panel 3, and a third positioning hole 32 corresponding to the positioning rod 26 is opened on the assembly block 28, and / or a fourth positioning hole 33 is opened on the support plate 11 corresponding to the positioning rod 26. After the pad 25 is removed from the pad groove 24, the pad 25 is placed between the U-shaped push plate 20 and the second tooth plate 23 and the bottom of the main panel 3, and the positioning rod 26 is aligned with the third positioning hole 32 and / or the fourth positioning hole 33. As the plug plate 9 is retracted, the support plate 11 moves toward the direction close to the main panel 3 until the positioning rod 26 passes through the third positioning hole 32 and / or the fourth positioning hole 33, thereby preventing the pad 25 from falling off the scaffolding during the turnover of the scaffolding.
