Description

Technical Field

[0001] This invention relates to the field of construction machinery technology, specifically to a self-climbing electric lifting device for the construction of staggered balconies. Background Technology

[0002] With the diversification of modern architectural design, split-level and staggered-level balcony structures have been widely used in residential buildings due to their rich spatial layers and excellent lighting and ventilation effects. These buildings feature staggered and discontinuous facades, and the narrow construction space and complex structural forms of the balconies present challenges. Conventional high-altitude work equipment generally suffers from poor adaptability, low construction efficiency, and insufficient safety guarantees, making it a technical hurdle in the construction field.

[0003] Currently, the main method for high-altitude operations during the construction of staggered balconies is to use specialized static support devices. While some existing static support devices designed for staggered balconies can be adapted and fixed to the staggered structure through adjustable wall mounts and diagonal braces, these devices are merely static support structures and lack independent lifting capabilities. They cannot adjust the working position according to the construction height, nor are they equipped with a working platform capable of supporting personnel and materials, resulting in severely insufficient practicality for construction.

[0004] Therefore, developing a special lifting device that can adapt to staggered structures, has an electric self-climbing function, is equipped with a retractable working platform, and is safe and stable is of great significance for solving the construction problems of staggered balconies and improving construction efficiency and safety. Summary of the Invention

[0005] This invention aims to provide a self-climbing electric lifting device for the construction of staggered-level balconies. To solve the technical problem, the technical solution provided by this invention is as follows: A self-climbing electric lifting device for the construction of staggered balconies includes a support column, an adjustable wall mount, and adjustable diagonal braces. The adjustable wall mount can be finely adjusted in multiple directions and is fixedly engaged with the wall or beam of the staggered balcony. The two ends of the adjustable diagonal braces are respectively hinged to the support column and the building structure to adapt to the staggered height difference and prevent tilting. A lifting assembly that can slide vertically along the support column is mounted on the support column. The lifting assembly includes a guide roller assembly, a rope traction mechanism, and an electric drive mechanism. The guide roller assembly conforms to the side wall of the support column to achieve vertical guidance and sliding. The electric drive mechanism pulls the lifting assembly vertically through the rope traction mechanism. A retractable lifting platform is fixedly mounted on the outside of the lifting assembly. The retractable lifting platform includes a fixed platform and a retractable extension plate. A safety guardrail is set around the lifting platform.

[0006] Furthermore, the guide roller assembly includes multiple sets of limiting rollers, which encircle and fit against the outer wall of the support column to achieve vertical sliding guidance and lateral limiting of the lifting component.

[0007] Furthermore, the rope traction mechanism includes a traction rope and a rope wheel assembly. The traction rope is wound around the outside of the rope wheel assembly, and both ends of the traction rope are fixedly connected to the top of the support column and the lifting assembly, respectively.

[0008] Furthermore, the electric drive mechanism includes a drive motor and a rope drum. The drive motor drives the rope drum to rotate in both directions, thereby realizing the winding and unwinding of the traction rope and driving the lifting assembly to rise and fall.

[0009] Furthermore, the lifting assembly is equipped with a rope anti-fall braking structure, which can instantly lock the lifting assembly to prevent it from falling when the rope slacks or breaks.

[0010] Furthermore, the retractable extension plate is slidably mounted on the fixed platform, and its extension length can be adaptively adjusted according to the actual width of the staggered balcony.

[0011] Furthermore, the fixed platform and the retractable extension plate are combined to form an enclosed load-bearing work surface for supporting construction personnel and construction materials.

[0012] Furthermore, the guardrail can be detachably fixed to the perimeter of the lifting platform to form an integrated work safety protection structure.

[0013] Furthermore, the adjustable wall mount has front-to-back and left-to-right fine-tuning functions to adapt to the installation height difference of walls and beams in staggered and split-level buildings.

[0014] Furthermore, the adjustable diagonal brace can adaptively adjust the angle of the height difference between staggered floors, providing inclined reinforcement support to the supporting columns and improving the overall structural stability.

[0015] The advantages of this invention are: This invention relates to a self-climbing electric lifting device for the construction of staggered balconies. Through adjustable wall mounts and diagonal braces, it achieves precise adaptation to staggered building structures. Utilizing a flexible lifting structure with roller guidance and rope traction, it operates smoothly with low noise and high fault tolerance, allowing for stable lifting along the columns. Equipped with a retractable lifting platform, it adapts to different balcony widths, supports construction personnel and materials, and integrates fall protection braking and guardrails for high safety. This device solves the construction problem of traditional equipment being unable to adapt to staggered structures, eliminating the need for repeated scaffolding erection, thus improving construction efficiency, reducing costs, and demonstrating strong practicality.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Example 1 A self-climbing electric lifting device for staggered-level balcony construction is mainly used for high-altitude construction operations such as insulation, plastering, painting, repair, and installation on the exterior facades of staggered-level and multi-level balconies. It addresses key industry pain points such as the inability of existing traditional support structures to perform autonomous lifting and lowering, the lack of a work platform, poor adaptability of traditional rack and pinion climbing structures (high noise levels, prone to jamming), and weak adaptability to varying floor levels in staggered-level buildings. Based on the existing adaptive staggered-level support base, this device innovatively adopts a roller-guided, rope-traction electric lifting structure. The overall structure is simple and stable, operates smoothly and quietly, and is highly adaptable, perfectly suited to various staggered-level and multi-level balcony construction scenarios with varying floor levels. It also integrates a retractable work platform and multiple safety protection structures, balancing practicality and operational safety, and meeting the needs of routine construction operations on staggered-level balconies in high-rise buildings.

[0021] like Figure 1 and Figure 2 As shown, this device comprises five main parts: a staggered adaptive support base, a vertical sliding lifting assembly, an electric rope drive mechanism, a telescopic lifting platform, and a safety protection and braking system. The staggered adaptive support base, serving as the overall load-bearing foundation, mainly includes support columns 1, multiple sets of adjustable wall mounts, and adjustable diagonal braces. It can be finely adjusted and fixed in multiple directions according to the wall position of the staggered balcony, the beam-slab height difference, and the building structure dimensions, providing a stable installation base for the entire lifting operation structure and fundamentally solving the problem that traditional construction equipment cannot adapt to staggered and multi-level building structures. The lifting assembly adopts a ring-shaped roller guide structure combined with flexible rope traction drive, replacing the traditional gear and rack rigid meshing climbing structure. This effectively reduces equipment wear and noise, improves lifting smoothness and structural fault tolerance, adapts to slight structural deviations in staggered buildings, and significantly improves the equipment's versatility.

[0022] Support column 1 is the core vertical load-bearing frame of this device. It is made of high-strength rectangular steel pipe in one piece, and is vertically arranged. The surface is ground, rust-removed, and coated with anti-corrosion paint. It has the characteristics of high load-bearing capacity, not easy to deform, corrosion-resistant, and long service life. It can bear personnel and material loads for a long time and meet the safety standards for high-altitude operations. The overall height of support column 1 can be adapted to the conventional floor height. There are no structural breaks in the vertical structure, which ensures that the lifting components slide smoothly without jamming and provides a stable vertical sliding reference for the lifting mechanism.

[0023] Multiple sets of adjustable wall mounts are evenly spaced vertically along the supporting column 1. The wall mounts adopt a split-type micro-adjustment structure. The base is fixed to the side wall of the supporting column 1, and the front end is equipped with an adjustable clamping seat. The clamping seat can achieve bidirectional micro-adjustment displacement in both forward and backward and left and right directions. The micro-adjustment stroke is adapted to the installation deviation of conventional staggered balcony walls and beams. The end of the wall mount is equipped with an arc-shaped snap-fit ​​groove, which can be stably snapped and fixed to the balcony wall, beam, eaves and other building structures. The positioning and fixation are completed by bolt locking. The evenly distributed wall mounts at multiple points can ensure the fit and connection stability between the supporting column 1 and the building structure, avoiding problems such as column suspension, offset, and swaying. It perfectly adapts to the staggered structural characteristics of staggered buildings and solves the defect of traditional fixed supports that cannot adapt to staggered height differences.

[0024] Adjustable diagonal braces are symmetrically arranged between the supporting column 1 and the building structure. The main body of the diagonal brace adopts a telescopic sleeve structure, with locking bolts installed between the sleeves. The overall length and support angle can be freely adjusted according to the actual height difference and tilt angle of the staggered balcony. The top and bottom of the adjustable diagonal brace are both hinged. The upper end is hinged to the hinge lug pre-set on the side wall of the supporting column 1, and the lower end is hinged to the fixed base pre-set on the building structure. This fixed base is the bottom fixed base 6, forming a triangular stable support structure. Through the coordinated reinforcement of multiple sets of adjustable diagonal braces, the lateral force and overturning moment generated by the equipment during high-altitude operations can be effectively offset, limiting the swaying and displacement of the supporting column 1, greatly improving the overall anti-overturning performance and structural stability of the device, and adapting to the construction support needs of various staggered balconies with large differences.

[0025] The outer side of the support column 1 is equipped with a lifting assembly that can slide freely vertically along the column. This lifting assembly, namely the lifting slide 2, is the core motion mechanism for the device to achieve autonomous climbing and lifting. It is mainly composed of a guide roller assembly, a component mounting base, a rope traction mechanism, and a fall protection braking structure. The guide roller assembly adopts a multi-set ring-shaped limiting roller structure, which is respectively arranged at the upper and lower ends and the left and right sides of the mounting base. Each set of rollers uses a wear-resistant rubber-coated metal wheel core structure, which not only ensures structural strength but also reduces sliding noise and column wear. The multiple sets of rollers together ring and fit against the outer wall of the support column 1 to form an all-round limiting and guiding structure, which can effectively limit the lateral offset, forward and backward swaying, and angular deflection of the lifting slide 2, ensuring that the lifting slide 2 slides vertically along the support column 1 throughout the entire process, eliminating problems such as lifting jamming, offset, and sticking. Meanwhile, the encircling roller structure has a certain tolerance range, which can accommodate the slight deformation and installation deviation of the staggered columns. Compared with the traditional rigid guide rail sliding structure, its adaptability and stability are greatly improved.

[0026] The rope traction mechanism, serving as the core of the lifting drive, comprises a high-strength traction rope and a directional pulley assembly. The pulley assembly includes a top fixed pulley and side guide pulleys. The top fixed pulley, also known as the top rope pulley 5, is fixedly installed at the top of the support column 1. The guide pulleys are positioned on the upper end of the lifting slide 2 mounting base and are used to orient and limit the traction rope, preventing it from shifting, derailing, or tangling. The traction rope is made of aviation-grade steel wire rope, characterized by high tensile strength, resistance to breakage, high toughness, and wear resistance. The traction rope passes around the top rope pulley 5, with one end fixed to the fixed suspension point at the top of the support column 1, and the other end passing around the guide pulley of the lifting slide 2 and then fixedly connected to the rope drum, forming a closed-loop traction transmission structure that ensures uniform traction force and smooth lifting operation.

[0027] The electric drive mechanism 4 is fixedly mounted inside the mounting base of the lifting slide 2. It mainly includes a drive motor, a reducer, and a rope drum. The drive motor is a low-speed, high-torque servo motor, paired with a planetary reducer to achieve speed reduction and torque increase, providing sufficient driving force for rope winding and unwinding to meet the lifting power requirements under full load conditions. The rope drum is coaxially fixed with the reducer output shaft. Through the forward and reverse rotation control of the drive motor, the rope drum is driven to rotate synchronously, thereby achieving uniform winding and unwinding of the traction rope. When the rope is winding, the lifting slide 2 is pulled to climb upward along the support column 1; when the rope is unwinding, the lifting slide 2 descends at a uniform speed relying on its own weight and the rope traction. The entire process is smooth and uniform in speed, without impact or jamming. Compared with the traditional gear and rack rigid drive structure, it has lower operating noise, less structural wear, and a longer service life.

[0028] To ensure safety during high-altitude operations, the lifting slide 2 is integrated with a rope anti-fall braking structure. This structure employs a mechanical self-locking braking principle. Under normal lifting conditions, the rope is taut, and the braking structure is unlocked, without affecting the normal lifting movement of the equipment. In the event of sudden malfunctions such as rope slackness, breakage, motor failure, or power interruption, the rope tension disappears instantly, and the anti-fall braking structure is triggered instantaneously by the spring force and gravity, quickly locking the side wall of the support column 1, achieving instantaneous locking and fixation of the lifting slide 2, eliminating the risk of platform fall, and comprehensively ensuring the safety of construction personnel and equipment. This mechanical anti-fall structure requires no electricity, is purely mechanically triggered, has a fast response speed, high reliability, and can adapt to various complex high-altitude operation conditions.

[0029] A retractable lifting platform 3 is fixedly mounted on the outer side of the lifting slide 2, serving as the core working platform for construction workers to stand and for construction materials to be stacked. The retractable lifting platform 3 includes a fixed platform and a retractable extension plate. The fixed platform is fixedly connected to the outer side of the mounting base of the lifting slide 2 by bolts. The entire structure is a high-strength square tube welded frame structure, with the plate surface covered with anti-slip patterned steel plate, possessing extremely strong load-bearing capacity and anti-slip performance, capable of supporting multiple construction workers, construction tools, and materials. The retractable extension plate is slidably mounted in the internal slide groove of the fixed platform. The slide groove is equipped with a silent sliding component and a limit locking structure. The extension length of the retractable extension plate can be freely adjusted according to the actual width of the staggered balcony, adapting to construction scenarios with balconies of different widths. After adjustment, the extension plate is fixed in place by locking bolts to prevent it from sliding or shifting during operation.

[0030] When fully extended, the fixed platform and the retractable extension plate form a complete, flat, enclosed load-bearing work surface. The surface is smooth, without protrusions or gaps, and is slip-resistant and wear-resistant, meeting various construction needs such as standing work, material stacking, and tool placement. The retractable lifting platform 3 is detachably equipped with safety guardrails around its four edges. These guardrails use a plug-in installation structure, making them easy to assemble and disassemble, and securely fixed. The guardrail height meets high-altitude work safety standards, effectively preventing accidental falls of personnel and materials, thus constructing a comprehensive work safety protection system. Furthermore, the plug-in guardrails can be removed during equipment storage and transportation, reducing the space occupied by the equipment and facilitating its storage and handling.

[0031] The specific installation and workflow of this device are as follows: First, based on the structural dimensions and height difference of the staggered balcony at the construction site, adjust the front-to-back and left-to-right positions of the adjustable wall mounts, and fix multiple sets of wall mounts to the balcony wall and beam structure respectively, completing the initial positioning and fixing of the support column 1; then, adjust the length and support angle of the adjustable diagonal brace so that both ends of the diagonal brace are hinged and locked to the column and the building structure respectively, with the lower end of the diagonal brace hinged to the bottom fixed base 6, forming a stable overall support base, ensuring that the column is vertical, without swaying or deviation. After completing the base installation, assemble the lifting slide 2, which integrates the guide roller group, electric drive mechanism 4, and anti-fall braking structure, onto the support column 1, lay out the traction rope, and complete the alignment and tensioning of the top rope wheel 5 and drum to ensure that the rope is evenly stressed and slides smoothly. Finally, assemble the telescopic lifting platform 3 and the outer guardrail, adjust the extension length of the extension plate according to the width of the balcony, lock and fix it to complete the overall installation and debugging of the equipment.

[0032] During operation, workers stand on the retractable lifting platform 3 and start the drive motor via the control panel. The motor drives the rope drum to rotate forward and retract the rope, pulling the lifting slide 2 vertically and smoothly upward along the supporting column 1. Once the designated construction height is reached, the motor stops, and the equipment is stationary, ready for balcony construction. When lowering is required, the motor is reversed to release the rope, and the lifting slide 2 descends at a uniform speed. The entire process is stable and controllable. In case of a sudden malfunction during operation, the anti-fall braking structure locks instantly, ensuring operational safety. For construction needs involving varying heights on staggered balconies, the platform's adjustable structure, using wall mounts and diagonal braces, can adapt to different floor structures. Furthermore, the platform's telescopic function accommodates balconies of varying widths, enabling seamless construction across the entire staggered balcony area.

[0033] Compared to existing technologies, this invention offers significant advantages: First, it retains the original patented staggered adaptive support core structure. Through multi-directional micro-adjustment of the wall-mounted base and adjustable-angle diagonal bracing, it perfectly adapts to the height differences in staggered and multi-level buildings, solving the industry problem that traditional lifting equipment is only suitable for single-level buildings and cannot adapt to staggered construction. Second, it innovatively adopts a roller-guided + rope-traction electric lifting architecture, replacing the traditional gear and rack rigid climbing structure. This results in smoother and quieter operation, less wear, and a higher fault tolerance rate. It can adapt to slight deformation of the columns and installation deviations, significantly improving equipment stability and service life. Third, it integrates a retractable lifting platform 3 and a fully enclosed protective structure, adapting to different balcony widths and providing standing and material lifting functions. This achieves an integrated design of support, lifting, operation, and protection, eliminating the need for additional scaffolding, significantly reducing construction costs and improving construction efficiency. Fourth, it is equipped with a purely mechanical fall arrest braking structure, which instantly self-locks in case of power failure or rope breakage, resulting in higher safety and fully meeting the safety standards for high-altitude construction. It has strong engineering practical value and market promotion prospects. The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
