Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a working platform. Background Technology

[0002] Currently, the commonly used suspended platform construction process involves fixing an extended frame (i.e., support) from the top floor of the structural roof using chemical bolts or embedded parts. Sufficient counterweights are used to weigh down one end of the support, and anti-tipping chains or steel cables are used to secure the counterweights and prevent slippage. The front beam of the support extends no more than 1.5 meters, is secured with rope clamps, and the rope end is tightened with U-bolts. One end of the wire rope is fixed to the support, and the other end is connected to the suspended platform hoist. The main drawbacks of this suspended platform construction process are as follows:

[0003] 1. The arrival of the suspended platform is delayed and can only be installed after the top layer of the roof construction is completed;

[0004] 2. Installation is difficult, requiring embedded parts to be installed on the roof or chemical anchors to fix the brackets, and extremely heavy counterweights to be hoisted to the top of the roof for use, which is a high-altitude operation and carries high risks.

[0005] 3. It occupies space on the top floor for construction, affecting construction efficiency;

[0006] 4. Construction quality cannot be inspected. Due to the high risk of this type of suspended platform construction, it is often only workers who can work on it. The construction effect depends entirely on the professional skills of the workers and cannot be supervised and managed. As a result, there are many problems with the exterior wall falling off later. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a working platform that helps improve construction efficiency and safety, and is simple and reliable to install.

[0008] To solve the above-mentioned technical problems, this utility model provides a working platform, including a suspended platform, a building machine frame, and a lifting system. The building machine frame is provided with a first walkway frame. The lifting system includes a traction rope connector, a traction rope, and a traction drive mechanism. The traction rope connector is located at the top of the first walkway frame and is connected to the building machine frame. The traction rope passes through the first walkway frame and is connected to the traction rope connector. The traction drive mechanism is used to retract and extend the traction rope to drive the suspended platform to rise and fall.

[0009] As an improvement to the above solution, the building machine bracket is also provided with uprights connected to the first walkway frame, and both ends of the traction rope connector are connected to the first walkway frame, or respectively connected to the uprights on opposite sides of the first walkway frame.

[0010] As an improvement to the above solution, the traction rope connector includes a first crossbeam, a second crossbeam, a first column, and a second column. The first crossbeam, the second crossbeam, the first column, and the second column enclose a frame. The first column and the second column are respectively connected to the upright or the first walkway frame. The traction rope is connected to at least one of the first crossbeam and the second crossbeam.

[0011] As an improvement to the above solution, the traction rope passes through the first walkway frame, the first crossbeam, and the second crossbeam in sequence from bottom to top, and is locked to at least one of the first crossbeam, the second crossbeam, and the first walkway frame.

[0012] As an improvement to the above solution, the traction rope connector further includes a support column, the two ends of which are connected to the first crossbeam and the second crossbeam, respectively.

[0013] As an improvement to the above solution, the support columns are set to at least two, the distance between the tops of the two support columns in the center of the frame is less than the distance between the bottoms of the two support columns in the center of the frame, and the traction rope is threaded between the two support columns in the center of the frame.

[0014] As an improvement to the above solution, the lifting system further includes a traction locking mechanism, which includes a fall arrestor body, a safety rope, a first swing arm, and a second swing arm. The fall arrestor body is fixedly connected to the suspended platform. The safety rope passes through the fall arrestor body and is fixedly connected to the traction rope connector. The first swing arm is rotatably connected to the fall arrestor body. A first roller is provided at the end of the first swing arm. The second swing arm is coaxially arranged at the end of the first swing arm with the first roller. A second roller is provided at the end of the second swing arm away from the first swing arm. The traction rope passes between the first roller and the second roller.

[0015] As an improvement to the above solution, the fall arrestor body and the first swing arm are provided with a limiting structure for limiting the rotation range of the first swing arm.

[0016] As an improvement to the above solution, the traction locking mechanism is arranged symmetrically at both ends of the suspension platform.

[0017] As an improvement to the above solution, the building machine bracket is also provided with a second walkway frame, and the first walkway frame is located below the second walkway frame. Both the first walkway frame and the second walkway frame are connected to the upright.

[0018] Implementing this utility model has the following beneficial effects:

[0019] This utility model discloses a working platform. A lifting system suspends the platform on a building construction machine frame. The traction rope connector of the lifting system is located at the top of the first walkway frame of the building construction machine frame and is connected to the frame. The traction drive mechanism can raise and lower the platform by extending and retracting the traction rope. Compared with traditional suspended platform installation structures, this embodiment expands upon the building construction machine frame. The suspended platform can be installed and constructed during floor construction, helping to shorten the project time. Its structure is relatively simple, eliminating the need for extension frames and counterweights, reducing the amount of wire rope used, and further reducing the problem of swaying caused by excessively long wire ropes, thus ensuring safety. The system's stability is improved, and with the traction rope connector installed at the top of the first walkway frame, the weight of the entire suspended platform and lifting system can be borne by the first walkway frame, reducing the stress on the connector between the traction rope connector and the building machine's hanging frame, resulting in higher installation reliability. In addition, the suspended platform can be raised and lowered along with the building machine's hanging frame under the overall control of qualified personnel, resulting in higher safety and stability during lifting and lowering. Management personnel can use the suspended platform to inspect the quality of wall construction, helping to ensure the quality of exterior wall work. At the same time, when the building machine's hanging frame stops lifting and lowering, the suspended platform can independently lift and lower within a certain range under the drive of the traction drive mechanism, providing good operational flexibility.

[0025] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 5As shown, this utility model discloses an embodiment of a working platform, including a suspended platform 1, a building machine frame 2, and a lifting system 3. The building machine frame 2 is provided with a first walkway frame 21. The lifting system 3 includes a traction rope connector 31, a traction rope 32, and a traction drive mechanism 33. The traction rope connector 31 is located on the top of the first walkway frame 21 and is connected to the building machine frame 2. The traction rope 32 passes through the first walkway frame 21 and is connected to the traction rope connector 31. The traction drive mechanism 33 is fixedly connected to the suspended platform 1. The traction drive mechanism 33 drives the rope disc to rotate through a reduction motor to tighten and release the traction rope 32, thereby driving the suspended platform 1 to rise and fall.

[0027] In this embodiment, the suspended platform 1 is suspended on the building construction machine frame 2 via the lifting system 3. The traction rope connector 31 of the lifting system 3 is located at the top of the first walkway frame 21 of the building construction machine frame 2, and is connected to the building construction machine frame 2. The suspended platform 1 can be raised and lowered by the traction drive mechanism 33 by raising and lowering the traction rope 32. Compared with the traditional suspended platform installation structure, the suspended platform 1 in this embodiment is an extension based on the building construction machine frame 2. The suspended platform 1 can be installed and constructed during the floor construction process, helping to shorten the project construction period. Moreover, its structure is relatively simple, without the need for extension frames and counterweights, reducing the amount of wire rope used and further reducing the problem of the suspended platform swaying due to excessively long wire ropes, thus improving safety. Furthermore, the traction rope connector 31 is installed on the top of the first walkway frame 21, and the weight of the entire suspended platform 1 and lifting system 3 can be borne by the first walkway frame 21, reducing the stress on the connector between the traction rope connector 31 and the building machine frame 2, thus improving installation reliability. In addition, the suspended platform 1 can be raised and lowered along with the building machine frame 2 under the overall control of qualified personnel, resulting in higher safety and stability in the lifting and lowering of the suspended platform 1. Management personnel can inspect the wall construction quality along with the suspended platform 1, which helps to ensure the quality of the exterior wall work. At the same time, when the building machine frame 2 stops lifting and lowering, the suspended platform 1 can be raised and lowered independently within a certain range under the drive of the traction drive mechanism 33, providing good operational flexibility.

[0028] The building construction machine frame 2 in this embodiment is further provided with uprights 22 and a second walkway frame 23. The first walkway frame 21 is located below the second walkway frame 23, and both the first walkway frame 21 and the second walkway frame 23 are connected to the uprights 22. Both ends of the traction rope connector 31 are connected to the first walkway frame 21, or to the uprights 22 on opposite sides of the first walkway frame 21 respectively. The first walkway frame 21 is located at the bottom of the entire building construction machine frame 2. The suspended platform 1 is connected to the first walkway frame 21 located at the bottom of the building construction machine frame 2 through the lifting system 3, so that the construction work on the suspended platform 1 and the construction work on the building construction machine frame 2 do not interfere with each other. To ensure the safety of the construction work on the first walkway frame 21 and the suspended platform 1, guardrails are provided on the outer perimeter of both the first walkway frame 21 and the suspended platform 1.

[0029] It should be noted that, depending on the construction needs, multiple suspended platforms can be combined to form a continuous outer platform, thereby improving the efficiency of construction operations.

[0030] Specifically, in combination Figure 3 and Figure 4 In this embodiment, the traction rope connector 31 includes a first crossbeam 311, a second crossbeam 312, a first column 313, and a second column 314, which together form a frame. The first column 313 and the second column 314 are both parallel to the uprights 22, and the first crossbeam 311 is located below the second crossbeam 312. The uprights 22 in this embodiment have multiple vertically arranged connecting holes to facilitate adjustment of the longitudinal spacing between the first walkway frame 21 and the second walkway frame 23, and also to facilitate the connection between the traction rope connector 31 and the building machine bracket 2. The first column 313 and the second column 314 are respectively connected to the uprights 22 or the first walkway frame 21, and the traction rope 32 is connected to at least one of the first crossbeam 311 and the second crossbeam 312. The traction rope 32 is a steel wire rope. One end of the traction rope 32 is connected to the traction drive mechanism 33, and the other end is locked to the traction rope connector 31 through a locking member. The hoist tightens and releases the steel wire rope to achieve the function of raising or lowering the suspended platform 1. In this embodiment, the suspended platform 1 is also equipped with a control box 4, which is electrically connected to the traction drive mechanism 33 and is used to control the lifting system 3 of the suspended platform 1.

[0031] Preferably, the traction rope 32 passes sequentially from bottom to top through the first walkway frame 21, the first crossbeam 311, and the second crossbeam 312, and is locked to at least one of the first crossbeam 311, the second crossbeam 312, and the first walkway frame 21 by U-bolts. This layered locking improves the reliability of the connection between the traction rope 32 and the traction rope connector 31 and the building machine bracket 2.

[0032] To improve the stability of the traction rope connector 31 structure, the traction rope connector 31 in this embodiment further includes a support column 315, the two ends of which are connected to the first crossbeam 311 and the second crossbeam 312, respectively. At least two support columns 315 are provided, and the distance between the tops of the two support columns 315 in the center of the frame is less than the distance between the bottoms of the two support columns 315 in the center of the frame. The traction rope 32 passes between the two support columns 315 in the center of the frame.

[0033] Combination Figure 5 To further enhance construction safety, the lifting system 3 in this embodiment also includes a traction locking mechanism. The traction locking mechanism includes a fall arrestor body 34, a safety rope 35, a first swing arm 36, and a second swing arm 37. The fall arrestor body 34 is fixedly connected to the suspended platform 1. The safety rope 35 passes through the fall arrestor body 34 and is fixedly connected to the traction rope 32 connector. The first swing arm 36 is rotatably connected to the fall arrestor body 34. A first roller 361 is provided at the end of the first swing arm 36. The second swing arm 37 is coaxially disposed at the end of the first swing arm 36 with the first roller 361. A second roller 371 is disposed at the end of the second swing arm 37 away from the first swing arm 36. The traction rope 32 passes between the first roller 361 and the second roller 371. The fall arrestor body 34 can employ a fall arrestor from the prior art, which can lock the safety rope 35 when it slides rapidly relative to the fall arrestor body 34, preventing the fall arrestor body 34 and the suspended platform 1 from falling. The fall arrestor body 34 is provided with a limiting structure for limiting the rotation range of the first swing arm 36. Specifically, the fall arrestor body 34 is provided with a limiting post 341, and the first swing arm 36 is provided with an arc-shaped groove 362. During normal operation, the limiting post 341 is directly above the pivot of the first swing arm 36 and the fall arrestor body 34, and the traction rope 32 can rise and fall relative to the first roller 361 and the second roller 371. When the platform tilts, the traction locking mechanism is triggered, and the other end of the limiting post 341 is engaged with the arc-shaped groove 362. The first roller 361 and the second roller 371 lock the traction rope 32 to prevent the suspended platform 1 from overturning.

[0034] In this embodiment, the traction locking mechanism is preferably arranged symmetrically at both ends of the suspension platform 1 to prevent the suspension platform 1 from tipping over to either side.

[0035] In this embodiment, the safety rope 35 used in the traction locking mechanism of the lifting system 3 is preferably a steel wire rope. It passes sequentially from bottom to top through the first walkway frame 21, the first crossbeam 311, and the second crossbeam 312, and is locked to at least one of the first crossbeam 311, the second crossbeam 312, and the first walkway frame 21 by U-bolts. This layered locking enhances the reliability of the connection between the safety rope 35 and the traction rope connector 31 and the building machine frame 2. Both the safety rope 35 and the traction rope 32 can be locked to the first walkway frame 21 and the traction rope connector 31, enabling multiple steel wire ropes of the lifting system 3 to be directly connected to the building machine frame 2 at multiple lifting points. Under the overall control of qualified personnel, the suspended platform 1 rises with the building machine frame 2, making the lifting and lowering of the suspended platform 1 safer and more stable.

[0036] In summary, implementing this utility model has the following beneficial effects:

[0037] 1. Since the suspended platform 1 is an extension of the building machine hanging frame 2, the structure is relatively simple, and it does not require additional supports, counterweights, and relatively less steel wire rope, which can significantly reduce costs;

[0038] 2. During the construction of each floor, such as during the last floor of structural construction or the period of the pergola floor, the suspended platform 1 on the building construction machine scaffold 2 can be released to carry out the construction of the exterior wall, which greatly advances the start time of wall construction and shortens the project period.

[0039] 3. The multiple steel wire ropes of the lifting system 3 are directly connected to the building machine frame 2 at multiple lifting points. Under the overall control of qualified personnel, the suspended platform 1 is lifted along with the building machine frame 2, ensuring the safety and stability of the lifting of the suspended platform 1.

[0040] 4. The distance between the suspended platform 1 and the building machine bracket 2 does not need to be too large, which can save the amount of wire rope used and reduce the swaying problem caused by excessively long wire ropes (from the roof to the ground) in general suspended baskets, making it safer and more reliable.

[0041] 5. As the safety and stability of the suspended platform 1 are improved, managers can use the suspended platform 1 to inspect the quality of the wall construction, which helps to ensure the quality of the exterior wall work.

[0042] 6. Multiple suspended platforms 1 can be combined to form an outer platform, improving the work efficiency of workers. Each suspended platform 1 has its own independent lifting system 3. Multiple suspended platforms 1 can be lifted simultaneously or individually, which improves the flexibility of the suspended platform 1.

[0043] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
