Description

Technical Field

[0001] This utility model relates to the field of scaffolding platform technology, and in particular to an expandable scaffolding platform hinged flap. Background Technology

[0002] Currently, existing scaffolding platforms (such as patent publication number: CN218176559U) disclose a scaffolding work platform and scaffolding. By setting up a support plate, connecting plate, lifting plate, through groove, power frame, drive wheel, base plate, support frame and driven wheel, when the drive wheel rotates, it can cooperate with the steel cable to drive the driven wheel to rotate. At the same time, during the transmission of the steel cable on the surface of the drive wheel and the driven wheel, it can drive the lifting plate to move along the inner cavity of the through groove, thereby raising the materials to be transported. This allows users on the top of the support plate to directly pick up the materials on the top of the lifting plate, and users on the ground can directly place the materials on the top of the lifting plate, avoiding the spillage of materials during the process of transporting them to the top of the support plate.

[0003] In the aforementioned patent, the scaffolding has a gap reserved on the side close to the wall to avoid wall protrusions and reserve space for construction operations. Construction tools and materials are prone to fall through the gaps, injuring workers below or passersby, creating a "falling object from height" safety hazard. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an expandable scaffolding platform hinged flap, which solves the technical problem of "falling objects from height" safety hazards caused by gaps left on the side of the scaffolding near the wall to avoid wall protrusions and reserve construction operation space.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An expandable scaffolding platform hinged flap includes a scaffolding body and two fixed plates. Each fixed plate has a support seat inside, a bearing plate is rotatably mounted on the top of each support seat, and an extension plate is slidably mounted on the side end of each bearing plate. Two pivot seats are fixedly installed at the end of each of the extension plates. A push rod is rotatably installed inside each pivot seat. A guide plate is slidably installed inside each of the support seats. The side end of each guide plate is rotatably connected to the push rod.

[0006] Preferably, a locking sleeve is slidably installed on both sides of each of the support bases, and a connecting sleeve is fixedly installed at the end of each of the locking sleeves; Each of the locking sleeves is provided with a pre-tightening bolt inside, and the thread helix angle of each connecting sleeve and the pre-tightening bolt is less than the friction angle.

[0007] Preferably, each of the guide slides has a drive screw rotatably mounted inside, and each drive screw also passes through the top of the support base; Each of the bearing plates is provided with insertion holes at both ends, and the insertion holes are also provided with threaded grooves inside; Each of the support bases is rotatably mounted with multiple bolts on its side end, and each of the support bases is provided with a guide groove inside; Each of the guide slide plates is provided with rubber sleeves at both ends, and each of the guide slide plates has a raised structure at both ends; Each of the support bases has a slot with the same shape as the locking sleeve inside.

[0008] Compared with the prior art, the present invention has the following beneficial effects; In this invention, the protrusion on the surface of the locking sleeve is tightly connected to the side end of the bearing plate. At the same time, the pre-tightening bolt has a mechanical self-locking characteristic because the thread helix angle is less than the friction angle. After being screwed into the threaded groove of the bearing plate insertion hole, it can securely lock the support base and the bearing plate. The bearing plate can be adjusted to adapt to the shape of the wall, preventing construction workers from stepping into gaps and tools or materials from falling through the gaps, thus increasing the protection capability.

[0009] In this invention, by moving the guide slide upward, the guide slide slides inside the support base, and the guide slide slide generates a thrust on the end of the push rod. The deflection of the push rod generates a force on the extension plate, allowing the extension plate to slide on the side end of the bearing plate, thereby expanding the support area. Each bearing plate and extension plate can be independently adjusted in angle and slid out, which can accommodate multiple protrusions on the outside of the wall. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: This application provides an expandable scaffolding platform with a hinged flap, effectively solving the problem of construction tools and materials easily falling through gaps in the scaffolding near the wall to avoid wall protrusions and reserve construction operation space, potentially injuring workers below or passersby and creating a "falling object" safety hazard. The convex strip on the locking sleeve surface is tightly connected to the side end of the bearing plate, and the pre-tightening bolt has a mechanical self-locking characteristic because the "thread helix angle is less than the friction angle". After being screwed into the threaded groove of the bearing plate insertion hole, it can firmly lock the support base and the bearing plate. The bearing plate can be adjusted to adapt to the wall shape, preventing construction workers from stepping into gaps and tools or materials from falling through the gaps, thus increasing the protection capability.

[0012] Example 1 like Figures 1-4 As shown, the technical solution in this application embodiment effectively solves the technical problem that, in order to avoid wall protrusions and reserve construction operation space, a gap is reserved on the side of the scaffolding near the wall, and construction tools and materials can easily fall through the gap, injuring workers below or passersby, creating a "falling object from height" safety hazard. The overall idea is as follows: To address the problems existing in the prior art, this utility model provides an expandable scaffolding platform hinged flap, including a scaffolding body 11 and two fixed plates 12. Each fixed plate 12 has a support seat 13 inside, and a bearing plate 14 is rotatably installed on the top of each support seat 13. An extension plate 15 is slidably installed on the side end of each bearing plate 14. By pushing the extension plate 15, the extension plate 15 can slide inside the bearing plate 14. The extension plate 15 can slide and unfold on the side end of the bearing plate 14, adjusting the area of ​​the bearing plate 14 and the extension plate 15. Each bearing plate 14 and extension plate 15 can be adjusted independently to adapt to different protruding wall surfaces. Two pivot seats 16 are fixedly installed at the end of each extension plate 15. A push rod 17 is rotatably installed inside each pivot seat 16. A guide plate 18 is slidably installed inside each support seat 13. The side end of each guide plate 18 is rotatably connected to the push rod 17. By moving the guide plate 18 upward, the guide plate 18 slides inside the support seat 13, and the guide plate 18 generates a thrust on the end of the push rod 17. The push rod 17 can rotate inside the pivot seat 16. The deflection of the push rod 17 generates a force on the extension plate 15, causing the extension plate 15 to slide on the side end of the bearing plate 14, expanding the support area and filling the distance between the scaffold body 11 and the wall. Each support base 13 has a locking sleeve 21 slidably installed on both sides. Each locking sleeve 21 has a connecting sleeve 22 fixedly installed at its end. By moving the locking sleeve 21 and the connecting sleeve 22, the locking sleeve 21 is first at the side end of the support base 13, and the locking sleeve 21 drives the connecting sleeve 22 to slide, so that the locking sleeve 21 is slidably inserted into the interior of the support base 13. At the same time, the connecting sleeve 22 remains at the side end of the bearing plate 14. The bearing plate 14 can be rotated to adjust the angle of the bearing plate 14. Meanwhile, the bearing plate 14 still slides and connects with the extension plate 15. Each locking sleeve 21 is equipped with a pre-tightening bolt 23 inside. The thread helix angle of each connecting sleeve 22 and the pre-tightening bolt 23 is less than the friction angle. By moving the locking sleeve 21 and the connecting sleeve 22, the locking sleeve 21 and the connecting sleeve 22 are slidably inserted into the side end of the bearing plate 14. The surface of the locking sleeve 21 is provided with a protrusion. The locking sleeve 21 mates with the side end of the bearing plate 14. The support seat 13 and the bearing plate 14 are fixed to each other by the locking sleeve 21, locking the angle of the bearing plate 14. By rotating the pre-tightening bolt 23 clockwise, the pre-tightening bolt 23 rotates inside the connecting sleeve 22. At the same time, the end of the pre-tightening bolt 23 rotates and inserts into the inside of the bearing plate 14. When the rotation of the pre-tightening bolt 23 is stopped, the connecting sleeve 22 and the pre-tightening bolt 23 can lock themselves, which is used to fasten the position of the locking sleeve 21 and the connecting sleeve 22. Each guide slide plate 18 has a drive screw 19 rotatably installed inside. Each drive screw 19 passes through the top of the support base 13. By rotating the drive screw 19 clockwise, the drive screw 19 rotates at the top of the support base 13. At the same time, the end of the drive screw 19 connects to the inside of the guide slide plate 18. The rotating drive screw 19 drives the guide slide plate 18 to slide upward. Each support plate 14 has a hole on both sides, and the hole also has a threaded groove. The synchronous sliding of the locking sleeve 21 and the connecting sleeve 22 allows the locking sleeve 21 and the connecting sleeve 22 to be continuously fixed to the side ends of the support plate 14. This can fix the angle of the support plate 14 and allow the support plate 14 to rotate around the two connecting sleeves 22. Each support base 13 has multiple bolts rotatably installed on its side end. Each support base 13 has a guide groove inside. By moving the support base 13, the support base 13 is inserted into the inside of the fixing plate 12. By tightening the screws, the fixing plate 12 and the support base 13 are assembled together.

[0013] Each guide slide plate 18 has a rubber sleeve 24 at both ends. The two ends of each guide slide plate 18 have a raised structure. The rubber sleeve 24 can rub against the drive screw 19 to prevent dust from entering the connection between the drive screw 19 and the guide slide plate 18. Each support 13 has a slot with the same shape as the locking sleeve 21 inside.

[0014] Example 2 This embodiment specifically discloses an expandable scaffolding platform hinged flap, including the following steps: The first step is to insert the support base 13 into the fixed plate 12. By tightening the multiple bolts on the side end of the support base 13, the fixed plate 12 and the support base 13 are firmly connected, so that the support base 13 becomes the basic carrier for the subsequent movement of the components and provides an installation reference for the adjustment of the bearing plate 14 and the extension plate 15.

[0015] Locking sleeves 21 are slidably installed at both ends of the support base 13. Connecting cylinders 22 are fixed to the ends of the locking sleeves 21. When the locking sleeves 21 are moved, they drive the connecting cylinders 22 to slide along the side ends of the support base 13, partially inserting the locking sleeves 21 into the support base 13. Simultaneously, the connecting cylinders 22 are positioned at the side end of the bearing plate 14 (the side end of the bearing plate 14 has a threaded slotted insertion hole). At this time, the bearing plate 14 can rotate around the connecting cylinders 22, thereby adjusting its tilt or horizontal angle. The bearing plate 14 and the extension plate 15 maintain a sliding fit, not affecting the subsequent sliding of the extension plate 15. Using the pre-tightening bolts 23 inside the locking sleeves 21, due to the engagement... The thread helix angle of the connecting sleeve 22 and the pre-tightening bolt 23 is less than the friction angle (possessing mechanical self-locking characteristics). When the pre-tightening bolt 23 is rotated clockwise, the pre-tightening bolt 23 rotates inside the connecting sleeve 22 and gradually screws into the threaded groove of the insertion hole at the side end of the bearing plate 14, so that the end of the pre-tightening bolt 23 is threadedly connected to the bearing plate 14. At the same time, the protrusion on the surface of the locking sleeve 21 is tightly connected to the side end of the bearing plate 14, together fixing the support seat 13 and the bearing plate 14, restricting the rotation of the bearing plate 14, realizing angle locking, and due to the self-locking property, the connecting sleeve 22 and the pre-tightening bolt 23 can maintain their position by themselves, further tightening the relative position of the locking sleeve 21 and the connecting sleeve 22.

[0016] The second step involves fixing two pivot seats 16 to the end of the extension plate 15. A push rod 17 is rotatably installed inside the pivot seat 16. The end of the push rod 17 is rotatably connected to the side end of a guide slide plate 18 slidably disposed inside the support seat 13. A drive screw 19 is rotatably installed inside the guide slide plate 18, passing through the top of the support seat 13. When it is necessary to expand the support area (to fill the gap between the scaffold body 11 and the wall), the drive screw 19 is rotated clockwise. The drive screw 19 rotates at the top of the support seat 13, and its end interacts with the inside of the guide slide plate 18 (through a threaded connection), driving the guide... The sliding plate 18 slides upward inside the support base 13. When the guide sliding plate 18 slides upward, it applies a thrust to the end of the push rod 17, causing the push rod 17 to rotate (deflect) inside the pivot base 16. The deflection of the push rod 17 generates a horizontal force on the extension plate 15, pushing the extension plate 15 to slide outward at the side end of the bearing plate 14, thereby increasing the combined support area of ​​the "bearing plate 14 + extension plate 15". Since each bearing plate 14 and extension plate 15 can be adjusted independently, it can adapt to the outer side of the wall with different protrusion shapes, improving the adaptability of the scaffolding platform to complex wall structures.
