[0002] In the field of building exterior wall construction, suspended scaffolding is the core equipment supporting the suspended platform and ensuring the safety of high-altitude operations. It mainly consists of a load-bearing main beam, suspension support components, and connecting frames. Fixed to the building's roof structure, it provides a stable working platform for construction workers and tools, and is widely used in exterior wall painting, curtain wall installation, and other scenarios. Currently, mainstream suspended scaffolding on the market adopts a fixed structure design, with its lateral support length determined during the production stage. All load-bearing components are rigidly connected by welding or high-strength bolts to form an integrated fixed frame, making it impossible to adjust the support length. Existing suspended scaffolding cannot adapt to the varying widths of exterior walls required for construction work. Utility Model Content

[0010] The lock seat is fixedly mounted on the extension frame, and the lock seat is provided with a first through hole for the lock tongue to pass through;

[0011] The pedal is hinged to the lock seat, and the two ends of the pedal at the hinge position are a foot pedal end and a pry end, respectively. The pry end is provided with a second through hole for the lock tongue to pass through.

[0012] The locking tongue includes a column, the top end of which passes through the second through hole and is fixedly connected to a first limiting plate, the bottom end of which passes through the first through hole, and a second limiting plate is fixedly connected to the column, the second limiting plate being located between the first through hole and the second through hole;

[0013] The elastic element is used to drive the second limiting plate closer to the location of the first perforation.

[0014] As a further alternative, the elastic element is a spring, which is sleeved on the column, with one end of the spring abutting against the second limiting plate and the other end abutting against the prying end.

[0039] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0040] refer to Figure 1-9 An embodiment of this utility model illustrates an adjustable building exterior wall construction scaffold support, including a main frame 1 and two extension frames 2. The main frame 1 includes a first platform 11, with first guardrails 12 on both sides of the first platform 11, and both ends of the first platform 11 are open structures. Multiple positioning parts 3 are spaced apart along the length of the first platform 11 on both sides. The two extension frames 2 are slidably disposed at both ends of the first platform 11. Each extension frame 2 includes a second platform 21, with second guardrails 22 on both sides of the second platform 21. An openable and closable door 23 is provided at the end of the second platform 21 away from the main frame 1. A locking mechanism 4 is provided on each extension frame 2, and the locking mechanism 4 is locked to one of the positioning parts 3 on the main frame 1 to achieve relative fixation between the extension frame 2 and the main frame 1.

[0041] Specifically, such as Figure 3As shown, the main frame 1 constitutes the central main body of the suspended platform support, and the first platform 11 provides a standing space for workers to operate and move around on the exterior wall of the building. For safety, first guardrails 12 are fixedly installed on both sides of the first platform 11 to effectively prevent falls. Simultaneously, the two ends of the first platform 11 are designed as open structures (not marked in the figure), providing physical space for the insertion and sliding of the extension frame 2. Furthermore, to achieve the positioning and fixing of the extension frame 2, multiple positioning parts 3 are spaced apart along the length direction on both sides of the first platform 11. In some embodiments, these positioning parts 3 can be a series of regularly arranged circular holes, pin holes, or other forms of positioning interfaces.

[0042] like Figure 5 As shown, two extension frames 2 are slidably mounted at both ends of the main frame 1. Each extension frame 2 includes a second platform 21, as shown... Figure 2 As shown, when the extension frame 2 is pulled out from the main frame 1, the second platform 21 and the first platform 11 together form a complete working platform with an extended length. Similarly, the second platform 21 has second guardrails 22 on both sides. When the extension frame 2 is fully extended, its second guardrails 22 and the first guardrails 12 of the main frame 1 form a continuous and uninterrupted safety protection side, while also providing fall protection. At the end of the second platform 21 furthest from the main frame 1, an openable and closable door 23 is installed. The door 23 facilitates personnel entry and exit from the platform and maintains the closed and safe position of the platform end during operation. Each extension frame 2 is also equipped with a locking mechanism 4, which can lock with the positioning part 3.

[0043] The working principle is as follows: When the total width of the suspended platform support needs to be adjusted to adapt to the building structure, the operator can first release the locking mechanism 4 from the current positioning part 3, and then push and pull the extension frame 2 along the length of the main frame 1. When the extension frame 2 slides to the desired position, so that the locking mechanism 4 on it can be aligned with another suitable positioning part 3 on the main frame 1, the locking mechanism 4 is operated to lock it to the positioning part 3, thereby fixing the extension frame 2 and the main frame 1 in the new relative position. In this way, the lateral support length of the entire suspended platform support can be adjusted flexibly and reliably.

[0044] In some embodiments, such as Figure 4 , Figure 6 as well as Figure 8As shown, the positioning part 3 includes two spaced positioning blocks 31, with a groove 32 formed between the two positioning blocks 31, and guide slopes 311 provided on the opposite far sides of the two positioning blocks 31; the locking mechanism 4 includes a lock seat 41, a pedal 42, a latch 43, and an elastic element 44; the lock seat 41 is fixedly mounted on the extension frame 2, and the lock seat 41 has a first through hole 411 for the latch 43 to pass through; the pedal 42 is hinged to the lock seat 41, and the two ends of the pedal 42 at its hinge position are a foot pedal end 421 and a prying end 42, respectively. 2. The prying end 422 is provided with a second through hole 423 for the locking tongue 43 to pass through; the locking tongue 43 includes a column 431, the top end of the column 431 passes through the second through hole 423 and is fixedly connected to a first limiting plate 432, the bottom end of the column 431 passes through the first through hole 411, and a second limiting plate 433 is fixedly connected to the column 431, the second limiting plate 433 being located between the first through hole 411 and the second through hole 423; the elastic member 44 is used to drive the second limiting plate 433 closer to the location of the first through hole 411.

[0045] Preferably, the elastic element 44 is a spring, which is sleeved on the column 431. One end of the spring abuts against the second limiting plate 433, and the other end abuts against the prying end 422.

[0046] Specifically, when the locking mechanism 4 and the positioning part 3 are locked, under the elastic force of the elastic element 44, the bottom end of the column 431 of the locking tongue 43 is pushed downward and just inserted into the slot 32 between the two positioning blocks 31. Due to the width limitation of the slot 32, the relative movement between the extension frame 2 and the main frame 1 is effectively prevented, and reliable locking is achieved.

[0047] When the width of the suspended platform bracket needs to be adjusted, the operator steps down on the foot pedal 421 of the pedal 42. According to the lever principle, pressing down on the foot pedal 421 causes the prying end 422 to tilt upward. The prying end 422 drives the first limiting plate 432 of the locking tongue 43 through the second through hole 423, thereby overcoming the elastic force of the elastic element 44 and lifting the entire locking tongue 43 upward, causing its bottom end to disengage from the slot 32 of the positioning block 31. At this time, the extension frame 2 can be slid.

[0048] As the sliding extension frame 2 moves to the new target position, the bottom end of the latch 43 / column 431 will contact the guide ramp 311 of the new set of positioning blocks 31. During the continued sliding, the guide ramp 311 will generate an upward component force on the bottom end of the latch 43, compressing the elastic element 44 and causing the latch 43 to temporarily retract until the bottom end of the latch 43 slides past the highest point of the positioning block 31, and then automatically springs into the slot 32 under the action of the elastic element 44.

[0049] Thus, in this embodiment, a foot-operated lever mechanism is used, eliminating the need for the operator to bend over and manually operate the pins or wrenches. Unlocking and locking can be completed simply by standing on the platform and using the feet, significantly reducing labor intensity and improving adjustment efficiency. The design of the guide ramp 311 allows the locking tongue 43 to automatically slide into the slot 32 during the sliding process of the extension frame 2. The locking method of the locking tongue 43 inserting into the slot 32, combined with the continuous clamping force provided by the elastic element 44, forms a rigid connection that is impact-resistant and vibration-resistant, ensuring the absolute stability of the suspended platform support under load.

[0050] In some embodiments, such as Figure 3 , Figure 5 , Figure 7 and Figure 9 As shown, the first platform 11 has a first guide plate 13 on each side, a first guide groove 131 on the inner side of the first guide plate 13, and a rotatable first guide wheel 132 on the inner side of the first guide plate 13; the second platform 21 has a second guide plate 24 on each side, a second guide groove 241 on the outer side of the second guide plate 24, and a rotatable second guide wheel 242 on the outer side of the second guide plate 24; wherein, the first guide wheel 132 is slidably engaged with the second guide groove 241, and the second guide wheel 242 is slidably engaged with the first guide groove 131.

[0051] Specifically, each side of the first platform 11 is provided with at least one first guide wheel 132, and each side of the second platform 21 is provided with at least one second guide wheel 242. That is, at least two first guide wheels 132 and two second guide wheels 242 are provided between the main frame 1 and the extension frame 2. The four-point contact structure of the four guide wheels constitutes a stable sliding system. When the extension frame 2 is pushed or pulled, the first guide wheel 132 rolls in the second guide groove 241, and the second guide wheel 242 rolls in the first guide groove 131, together constraining the extension frame 2 so that it can only slide smoothly along the longitudinal axis of the main frame 1.

[0052] The use of guide wheels rolling within guide grooves transforms sliding friction into rolling friction, significantly reducing operating force and making pushing and pulling easier. More importantly, it allows the extension frame 2 to withstand greater vertical loads and overturning moments. This ensures that the extension frame 2 will not jam or wobble even under eccentric loads, resulting in extremely smooth movement. The cooperation between the first guide wheel 132 and the second guide groove 241, and between the second guide wheel 242 and the first guide groove 131, forms a mutually constraining guiding system. This effectively prevents the extension frame 2 from detaching from the main frame 1 under lateral forces or vibrations, greatly enhancing the safety and reliability of the equipment.

[0053] In some embodiments, the first guide groove 131 and the second guide groove 241 are both C-shaped grooves. This further prevents the first guide wheel 132 and the second guide wheel 242 from disengaging from the second guide groove 241 and the first guide groove 131, and further ensures smooth and reliable sliding between the main frame 1 and the extension frame 2.

[0054] In some embodiments, such as Figure 1 As shown, the main frame 1 has suspension beams 14 at both ends. The suspension beams 14 can be used to connect the suspension system to facilitate the suspension of the basket support.

[0055] It should be noted that the suspension system (including but not limited to wire ropes, hoists, safety locks, etc.) connected to the suspension beam 14 of the suspended platform support involved in the embodiments of the present invention can be implemented using conventional techniques known in the art. This suspension system itself is not an improvement on the technical solution of the present invention; its specific structure and working principle are well known to those skilled in the art, and therefore will not be described in detail here. The scope of protection of the present invention extends only to the adjustable suspended platform support structure itself and should not be construed as a limitation on the connection method of a specific suspension system.

[0056] In summary, this application provides an adjustable suspended platform support for building exterior wall construction. By sliding extension frames 2 at both ends of the main frame 1 and utilizing a locking mechanism 4 in conjunction with positioning parts 3 at different positions, the total width of the entire suspended platform support can be adjusted in stages. This allows a single set of equipment to be compatible with building structures of different widths, significantly improving the equipment's versatility and adaptability to different work spaces.

[0057] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
