Description

Technical Field

[0001] This invention relates to the field of electric suspended platform technology, and in particular to an electric suspended platform for construction engineering. Background Technology

[0002] When working at heights in construction, most construction projects use electric suspended platforms on parapet walls to facilitate wall work. However, the working area of ​​a single suspended platform is limited, so the platform's support frame needs to be constantly moved to complete the work on the entire wall surface. Wall work involves multiple steps, not just one. Conventional suspended platform construction requires repeated dismantling and installation of the platform's support frame.

[0003] Based on existing technology, it has been found that conventional balanced suspended platforms have counterweights fixedly installed at the non-load-bearing end of the balance bar. These counterweights generate a counter-torque based on their own weight, thereby offsetting the load at the load end and maintaining the overall force balance and horizontal stability of the balance bar. However, in actual working conditions, as the weight of materials, tools, or loads on the load end increases, the overturning moment generated on the load side also increases. The original fixed number and weight of counterweights cannot match the changed load difference, and the torque balance is broken. At this time, the operators need to manually add counterweights of the corresponding specifications to adjust the total counterweight load at the non-load end, thereby offsetting the increased load torque at the load end and restoring the overall stability of the balance bar, ensuring the safety of the suspended platform operation.

[0015] The present invention provides an improved electric suspended platform for construction projects, which, compared with the prior art, has the following improvements and advantages:

[0016] Firstly, compared to the traditional manual adjustment method, this invention eliminates the need for workers to climb or manually push the rear support, significantly reducing the workload and safety risks of manual operation at height. At the same time, it improves the position adjustment accuracy of the rear support, ensuring that the rear support can be accurately moved to a position that matches the working range and balance requirements, thus providing a guarantee for the overall balance of the suspended platform and the safety of the operation. It is especially suitable for the flexible adjustment needs of different working points in large-scale construction projects.

[0017] Secondly, multiple steel ropes are laid between the rear hanging ring and the lower support position. When the load of the suspended platform increases, the bearing moment at the front end increases, driving the movable rear support to move closer to the rear hanging ring, causing the upper and lower steel wire ropes to shift laterally. As the displacement of the rear support increases, the degree of cross-entanglement of the multiple parallel steel wire ropes gradually increases, and the overall tension of the rope group automatically increases, so that the greater the load, the stronger the tensioning effect. When the load decreases, the overturning moment decreases, the rear support moves away from the rear hanging ring in the opposite direction, the lateral displacement of the steel wire rope decreases, the degree of entanglement naturally decreases, and the rope tension is released synchronously, thus automatically adjusting the tension and relaxation throughout the entire process.

Detailed Implementation

[0034] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides an improved electric suspended platform for construction engineering. The technical solution of this invention is as follows:

[0036] Example 1

[0037] like Figures 1 to 8 As shown, this embodiment of the invention provides an electric suspended platform for construction engineering, including a horizontally arranged load-bearing beam 1. An adjustment mechanism for adjusting the height is provided on the outer side of the load-bearing beam 1. A rear support 18 is provided on the outer side of the load-bearing beam 1. A moving component is provided on the outer side of the load-bearing beam 1, which enables the rear support 18 to move along the load-bearing beam 1. A support structure is provided at the bottom of the rear support 18 to support it. Multiple vertical rods are fixed on the outer side of the rear support 18, and multiple counterweights 19 are slidably sleeved on each vertical rod.

[0038] As described above, the horizontal setting of the load-bearing beam 1 ensures uniform stress distribution on the entire suspended platform, avoiding structural damage caused by localized stress concentration, and is suitable for the load-bearing requirements of high-altitude operations in construction projects. The adjustment mechanism allows for flexible adjustment of the suspended platform height to meet the height requirements of different floors and work positions, improving operational flexibility. The rear support 18, in conjunction with the counterweight 19, achieves front-to-back balance of the suspended platform. The movable component allows the rear support 18 to move along the load-bearing beam 1, facilitating adjustments to the balance position according to the work area and adapting to different work scenarios. The support structure provides stable support for the rear support 18, reducing the load on the load-bearing beam 1 and improving the overall stability of the suspended platform. The vertical rods with sliding counterweight 19 facilitate the addition and reduction of counterweight 19 to meet the balance requirements under different work loads, while also preventing the counterweight 19 from falling off, improving safety. At the same time, the arrangement of multiple vertical rods and counterweight 19 can distribute the counterweight pressure and prevent localized structural overload.

[0039] Specifically, the adjustment mechanism includes an inverted T-shaped rod 2, with positioning plates 3 welded and fixed to both ends of the T-shaped rod 2, and positioning holes provided at the four corners of the positioning plate 3.

[0040] As can be seen from the above, the inverted T-shaped rod 2 structure has both vertical support and lateral force bearing capacity, with strong overall rigidity, and can stably withstand the vertical load and horizontal force of the suspended platform, and is not easily deformed; the positioning plates 3 welded to both ends of the T-head can increase the contact area with the installation surface, disperse pressure, and avoid damage to the positioning point due to concentrated force; the positioning plates 3 have positioning holes at the four corners, which facilitates the fixing of the adjustment mechanism to the building wall or supporting structure with bolts, ensuring the stability of the adjustment mechanism installation, preventing loosening or displacement during high-altitude operations, and ensuring operational safety.

[0041] Specifically, the adjustment mechanism also includes a positioning sleeve 4 and an adjustment rod 5. The adjustment rod 5 is slidably inserted into the non-T-head end of the T-shaped rod 2. One end of the adjustment rod 5 is fixed to the positioning sleeve 4. The load-bearing beam 1 is slidably inserted into the positioning sleeve 4. Limiting holes are provided on the outer side of the adjustment rod 5 and the outer side of the non-T-head end of the T-shaped rod 2. A limiting bolt 6 is slidably inserted into the aligned limiting holes.

[0042] As described above, the adjusting rod 5 is slidably inserted into the T-shaped rod 2, allowing for flexible adjustment of its extension length. This, in turn, drives the positioning sleeve 4 and the load-bearing beam 1 to adjust their height, adapting to different working height requirements and providing convenient adjustment. The load-bearing beam 1 is slidably inserted into the positioning sleeve 4, facilitating its installation, disassembly, and fine-tuning. Simultaneously, the positioning sleeve 4 serves to limit and guide the load-bearing beam 1, preventing it from shifting laterally. The limiting hole, in conjunction with the limiting bolt 6, allows for quick locking of the position after the adjusting rod 5 is adjusted to its designated position, preventing the adjusting rod 5 from sliding during operation and ensuring stability after height adjustment, thus preventing safety accidents caused by height deviation.

[0043] Specifically, fixing holes are provided on the outer side of the load-bearing beam 1 and the outer side of the positioning sleeve 4, and a fixing bolt 7 is slidably inserted into the aligned fixing holes.

[0044] As can be seen from the above, the fixing hole and the fixing bolt 7 can be used to firmly fix the load-bearing beam 1 and the positioning sleeve 4, further improving the stability of the connection between the two, preventing the load-bearing beam 1 from sliding or shaking in the positioning sleeve 4, and avoiding displacement of the load-bearing beam 1 during high-altitude operations; the double fixing (limiting bolt 6 locks the adjusting rod 5, and fixing bolt 7 fixes the load-bearing beam 1 and the positioning sleeve 4) can improve the overall firmness of the adjustment mechanism, distribute the force, adapt to the complex stress environment of high-altitude operations in construction projects, and reduce the risk of structural loosening.

[0045] Specifically, the top of the positioning sleeve 4 is fixed with an upper bracket 8, and the two ends of the load-bearing beam 1 are respectively slidably connected with a front hanging ring 9 and a rear hanging ring 10. The upper bracket 8, the front hanging ring 9 and the rear hanging ring 10 are provided with a tensioning structure. The front hanging ring 9, the rear hanging ring 10 and the outer side of the load-bearing beam 1 are all provided with connecting holes, and a locking bolt 11 is slidably inserted into the relatively aligned connecting holes.

[0046] As can be seen from the above, the upper bracket 8 provides a stable installation fulcrum for the tensioning structure, ensuring that the tensioning structure can function properly; the front hanging ring 9 and the rear hanging ring 10 are slidably inserted into both ends of the load-bearing beam 1, making it easy to adjust the position of the hanging rings to adapt to tensioning structures of different lengths and operational needs, while also being flexibly disassembled for easy transportation and storage of the suspended platform; the tensioning structure can pull the front hanging ring 9 and the rear hanging ring 10, further improving the stress stability of the load-bearing beam 1 and preventing the ends of the load-bearing beam 1 from sagging or shifting; the connecting hole cooperates with the locking bolt 11 to firmly fix the front hanging ring 9 and the rear hanging ring 10 to the load-bearing beam 1, preventing the hanging rings from sliding, ensuring the tensioning effect of the tensioning structure, and improving the overall structural stability of the suspended platform.

[0047] Specifically, the tensioning structure includes a support roller 12, two spiral buckles 13, and a steel wire rope 14. The top of the upper bracket 8 is fixed with a bearing seat, and the support roller 12 and the bearing seat form a rotational fit. The tops of the front hanging ring 9 and the rear hanging ring 10 are both fixed with fastening posts 15. One end of the two spiral buckles 13 is fastened to the two fastening posts 15 respectively. The two ends of the steel wire rope 14 are fixed to the other ends of the two spiral buckles 13 respectively. The steel wire rope 14 is in contact with the support roller 12.

[0048] As can be seen from the above, the rotational cooperation between the support roller 12 and the bearing seat reduces the friction between the wire rope 14 and the support roller 12, preventing long-term friction damage to the wire rope 14 and extending its service life. It also ensures smooth, uninterrupted pulling of the wire rope 14. The spiral buckle 13 allows for flexible adjustment of the tension of the wire rope 14, facilitating adjustments to the pulling force based on the stress on the load-bearing beam 1, ensuring effective tension. It also allows for quick adjustment if the wire rope 14 becomes loose, improving operational safety. The fastening column 15 facilitates the installation and removal of the spiral buckle 13. The wire rope 14 connects the spiral buckle 13 and the hanging ring, forming a stable pulling structure with the front hanging ring 9, rear hanging ring 10, and upper support 8. This disperses the stress on the load-bearing beam 1, preventing deformation. Furthermore, the wire rope 14 has high strength and load-bearing capacity, meeting the load requirements of high-altitude operations.

[0049] Specifically, multiple reinforcing ribs 16 are fixed together between the positioning sleeve 4 and the adjusting rod 5, and between the upper bracket 8 and the positioning sleeve 4.

[0050] As can be seen from the above, the reinforcing rib 16 can enhance the connection strength between the positioning sleeve 4 and the adjusting rod 5, and between the upper bracket 8 and the positioning sleeve 4, disperse the force at the connection, and avoid problems such as breakage and deformation at the connection due to concentrated force. The even distribution of multiple reinforcing ribs 16 can further improve the overall rigidity and stability of the structure, adapt to the complex stress environment of high-altitude operations in construction projects, extend the service life of the suspended platform, and reduce maintenance costs.

[0051] Specifically, the non-T-head end of the T-shaped rod 2 and the T-head end of the T-shaped rod 2 are both fixed with a diagonal bracing beam 17.

[0052] As can be seen from the above, the diagonal bracing beam 17 can form a triangular support structure between the T-head end and the non-T-head end of the T-shaped rod 2. The triangular structure has good stability and anti-deformation ability, which can enhance the overall rigidity of the T-shaped rod 2 and prevent the T-shaped rod 2 from bending or deforming when subjected to vertical loads and horizontal forces. At the same time, the diagonal bracing beam 17 can distribute the force on the T-shaped rod 2 and transfer the load to the positioning plate 3, further improving the load-bearing capacity and stability of the adjustment mechanism and ensuring the safety of high-altitude operations.

[0053] Specifically, the moving assembly includes a sliding sleeve 20, two rolling rollers 21, a servo motor 22, an externally threaded rod 23, an internally threaded sleeve 24, and two fixed ears 25. The two ends of the externally threaded rod 23 are respectively rotated with the two fixed ears 25. The servo motor 22 and the two fixed ears 25 are fixed to the load-bearing beam 1. The output shaft of the servo motor 22 is coaxially fixed with the externally threaded rod 23. The two ends of the externally threaded rod 23 are respectively rotated with the two fixed ears 25. The externally threaded rod 23 is installed in the internally threaded sleeve 24 through external threads. The internally threaded sleeve 24 is fixed to the sliding sleeve 20. The entire sliding sleeve 20 is sleeved on the load-bearing beam 1. The two rolling rollers 21 are both arranged inside the sliding sleeve 20 and are distributed vertically. The rolling rollers 21 are rotated with the sliding sleeve 20 and are in contact with the load-bearing beam 1.

[0054] As described above, the servo motor 22 provides stable power and can precisely control the rotation of the external threaded rod 23, thereby driving the internal threaded sleeve 24 and the sliding sleeve 20 to move along the load-bearing beam 1, achieving precise position adjustment of the rear support 18, adapting to the balance requirements of different working scenarios, and achieving high adjustment efficiency and high precision. The external threaded rod 23 and the internal threaded sleeve 24 cooperate to ensure smooth transmission and strong load-bearing capacity, ensuring that the sliding sleeve 20 moves stably without shaking. The two fixed ears 25 provide stable support for the external threaded rod 23, ensuring smooth rotation of the external threaded rod 23 and preventing deviation. The sliding sleeve 20 is fitted on the load-bearing beam 1, and with the upper and lower distributed rolling rollers 21, the friction between the sliding sleeve 20 and the load-bearing beam 1 can be reduced, making the movement of the sliding sleeve 20 smoother. At the same time, the rolling rollers 21 can limit the sliding sleeve 20, preventing lateral deviation of the sliding sleeve 20 and improving the stability of the moving components. The overall structure has a high degree of automation, reducing the workload of manual adjustment, improving work efficiency, and reducing the safety risks of manual operation.

[0055] Specifically, the support structure includes a support plate 26, four adjusting screws 27, and four casters 28. The support plate 26 is fixed to the rear bracket 18. The four corners of the support plate 26 are provided with internal threaded holes. The four adjusting screws 27 are screwed into the four internal threaded holes respectively, and the four adjusting screws 27 are fixed to the four casters 28 respectively.

[0056] As described above, the support plate 26 is fixed to the rear bracket 18, which increases the contact area between the support structure and the rear bracket 18, disperses the support pressure, and avoids localized stress concentration on the rear bracket 18. Four adjusting screws 27 are respectively screwed to the four corners of the support plate 26, allowing for flexible adjustment of the support height by rotating the screws 27 to adapt to different ground flatness levels, ensuring the stability of the rear bracket 18 and preventing the suspended platform from tilting due to uneven ground. The casters 28 facilitate the movement of the rear bracket 18, and together with the moving components, allow for flexible repositioning of the rear bracket 18. The casters 28 can also be locked to fix the position during suspended platform operation, preventing the rear bracket 18 from sliding, thus balancing ease of movement and support stability. The support design at the four corners forms a stable support surface, improving the anti-tipping ability of the rear bracket 18 and ensuring safety during high-altitude operations.

[0057] Working principle:

[0058] Step 1: First, align the T-shaped rod 2 and positioning plate 3 of the adjustment mechanism with the building's pre-set support structure, align the positioning holes at the four corners of the positioning plate 3, insert the bolts and tighten them to ensure that the T-shaped rod 2 is firmly connected to the building's support structure, providing a stable installation foundation for the entire suspended platform and preventing the adjustment mechanism from loosening or shifting during high-altitude operations.

[0059] Step Two: Slide the adjusting rod 5, which is inserted into the non-T-end end of the T-bar 2, to synchronously raise and lower the positioning sleeve 4 fixed thereto. This adjusts the height of the load-bearing beam 1 inserted into the positioning sleeve 4 until the load-bearing beam 1 reaches the required working height. At this point, align the adjusting rod 5 with the limiting hole on the outside of the non-T-end end of the T-bar 2, insert the limiting bolt 6 and tighten it to initially fix the position of the adjusting rod 5. Then align the load-bearing beam 1 with the fixing hole on the outside of the positioning sleeve 4, insert the fixing bolt 7 and tighten it to achieve a firm connection between the load-bearing beam 1 and the positioning sleeve 4. This double fixing ensures the stability of the load-bearing beam 1's height and prevents height deviation during operation.

[0060] Step 3: Start the servo motor 22 of the moving component. The output shaft of the servo motor 22 drives the external threaded rod 23, which is fixed to the same axis, to rotate. Since the external threaded rod 23 is installed in the internal threaded sleeve 24 through the external thread, and the internal threaded sleeve 24 is fixed to the sliding sleeve 20, and the sliding sleeve 20 is sleeved on the load-bearing beam 1, when the external threaded rod 23 rotates, it will drive the internal threaded sleeve 24 and the sliding sleeve 20 to move smoothly along the load-bearing beam 1, thereby driving the rear support 18 connected to the sliding sleeve 20 to move synchronously until the rear support 18 moves to a position that matches the working range and balance requirements. Then, turn off the servo motor 22. After completion, the position of the support 18 is positioned.

[0061] Step 4: Adjust the four corner screws 27 of the support plate 26 in the rotating support structure. Since the adjusting screws 27 are screwed into the internal threaded holes of the support plate 26, during rotation, the adjusting screws 27 will drive the bottom casters 28 to rise and fall. Adjust the height of the four casters 28 one by one according to the flatness of the working ground to make the support plate 26 stably fit the ground and ensure that the rear support 18 is evenly stressed. After adjustment, lock the four casters 28 to prevent the rear support 18 from slipping during operation, provide stable support for the rear support 18, and reduce the stress on the load-bearing beam 1.

[0062] Step 5: Depending on the size of the workload, slide the counterweights 19 one by one onto the vertical rods on the outside of the rear support 18. By increasing or decreasing the number of counterweights 19, adjust the front and rear force balance of the suspended platform to prevent it from tilting forward or backward. At the same time, ensure that each counterweight 19 is securely fitted to prevent it from falling off during operation, thereby further improving the overall stability of the suspended platform. Alternatively, repeat step 4.

[0063] Step Six: Adjust the two spiral buckles 13 of the tensioning structure. By rotating the spiral buckles 13, adjust the length of the wire rope 14 to bring it into a tensioned state. At this time, the wire rope 14 is in close contact with the support roller 12 at the top of the upper bracket 8. Since the support roller 12 and the bearing seat form a rotational fit, the friction between the wire rope 14 and the support roller 12 can be reduced. Then, check the connection between the front hanging ring 9, the rear hanging ring 10 and the load-bearing beam 1, ensuring that the connecting holes on the outer sides of the three are aligned. Insert the locking bolts 11 and tighten them to firmly fix the front hanging ring 9 and the rear hanging ring 10 to the load-bearing beam 1. This allows the upper bracket 8, the front hanging ring 9, and the rear hanging ring 10 to form a stable tension structure through the wire rope 14 and the spiral buckles 13, distributing the force on the load-bearing beam 1 and preventing deformation of the load-bearing beam 1.

[0064] Step Seven: After completing all the above debugging steps, the suspended platform can be put into high-altitude operation. During the operation, all structures work together: the adjustment mechanism keeps the height of the load-bearing beam 1 stable, the moving components and support structure ensure that the rear support 18 is fixed in position and reliably supported, the counterweight 19 maintains the balance of the suspended platform, and the tensioning structure further improves the overall rigidity and stability. After the operation is completed, the counterweight 19 must be removed first, then the locking bolts 11, fixing bolts 7, and limit bolts 6 must be loosened in sequence, the adjusting rod 5 is adjusted to lower the load-bearing beam 1, and finally the connecting bolts between the adjustment mechanism and the building support structure are removed to complete the disassembly and storage of the equipment.

[0065] Example 2

[0066] like Figures 9 to 13As shown, a tightening mechanism is provided on the outer side of the rear bracket 18. The tightening mechanism includes a fixed plate 40, which is fixed to the ground. A concave plate 41 is fixed on the outer side of the fixed plate 40. A rotating column 42 is rotatably installed in the concave opening of the concave plate 41. A rotating block 30 is rotatably installed in the concave opening of the rear hanging ring (10). A bracket 31 is fixed on the outer side of the rotating block 30. A multi-faceted column 32 is slidably inserted into the outer side of the bracket 31. A limit plate 34 is fixed at one end of the multi-faceted column 32. A return spring 33 is sleeved on the outer side of the multi-faceted column 32, and the two ends of the return spring 33 are in contact with the bracket 31 and the limit plate 34, respectively. Multiple steel rods are fixed together at opposite ends of the multi-faceted column 32 and the rotating block 30. The rear support 18 has a rotating hole on its outer side, and a rotating cylinder 35 is rotatably installed inside the rotating hole. Each steel rope 29 passes through the rotating cylinder 35. A support plate 38 is fixed to the outer side of the rear support 18. A rotating shaft is rotatably installed on the outer side of the support plate 38. A second bevel gear 37 is fixed to one end of the rotating shaft and is coaxially arranged with it. A first bevel gear 36 is fixed to one end of the rotating cylinder 35 and is coaxially arranged with it. The first bevel gear 36 meshes with the second bevel gear 37. A first synchronous pulley 39 is fixed to the other end of the rotating shaft and is coaxially arranged with it. A second synchronous pulley 43 is fixed to one of the rolling rollers and is coaxially arranged with it. The first synchronous pulley 39 and the second synchronous pulley 43 are together fitted with a synchronous belt 44.

[0067] Working principle: When the load on the electric suspended platform changes, the increased load at the front end generates an overturning moment, driving the moving component to move the rear support 18 closer to the rear hanging ring along the load-bearing beam. Simultaneously, the rolling rollers inside the moving component rotate synchronously, transmitting power through the second synchronous pulley 43, synchronous belt 44, and first synchronous pulley 39, driving the rotating shaft and the second bevel gear 37 to rotate synchronously. Utilizing bevel gear meshing, the first bevel gear 36, along with the rotating cylinder 35, rotates synchronously. Multiple steel ropes 29 are connected at one end between the rotating block 30 and the multi-faceted column 32. The steel ropes 29 pass through the rotating cylinder 35 on the rear support 18. When the rotating cylinder 35 rotates, it twists and gathers the multiple steel ropes 29. The greater the operating load, the greater the movement distance of the rear support 18 towards the rear hanging ring, the longer the rotation stroke of the rolling roller, and the more rotations of the rotating drum 35. This continuously increases the degree to which the multiple steel ropes 29 intertwine and converge, thereby automatically tightening the steel ropes 29, increasing the overall tension, and offsetting the slack caused by the downward deflection of the load-bearing beam. When the load on the suspended platform decreases and the overturning moment decreases, the rear support 18 moves away from the rear hanging ring in the opposite direction. Simultaneously, the return spring 33 continuously pushes the limit plate 34 and the multi-faceted column 32, cooperating with the movable structure of the rotating block 30 and the support 31 to provide elastic compensation margin for the steel ropes 29. The rotating drum 35 rotates slightly in the opposite direction, reducing the degree of entanglement of the multiple steel ropes 29 and automatically releasing the tension, preventing the steel ropes 29 from being too tight for a long time, which could cause structural overload and wire wear. The rotating mounting structure of the concave plate 41, rotating column 42, and rotating block 30 can ensure that the angles of the two ends of the steel rope 29 can be adaptively deflected, preventing the steel rope 29 from bending and jamming or rubbing and sticking. The sliding fit of the multi-faceted column 32 and the combination of the return spring 33 realize flexible buffering and automatic reset, so that the entire tightening mechanism can achieve fully automatic adaptive adjustment of heavy load self-tightening and light load self-loosening according to the load size and the displacement of the rear support 18. The whole process is mechanically linked and no manual adjustment is required.
