Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation equipment technology, and in particular to a suspended basket suspension mechanism. Background Technology

[0002] Suspended platforms, as a commonly used type of construction machinery for working at heights, are widely used in modern construction projects for tasks such as curtain wall installation, exterior wall cleaning, insulation construction, and maintenance, offering significant advantages over traditional scaffolding. However, existing standard suspended platform suspension mechanisms, especially those relying on counterweights as an anti-overturning measure, typically require the erection of massive support structures and the stacking of numerous counterweights on the building's roof.

[0003] This traditional method has several shortcomings: First, the massive support structure and numerous counterweights occupy valuable roof space, causing inconvenience and impacting subsequent construction of the roof's waterproofing and insulation layers. Sometimes, roof repairs can only proceed after the suspended platform is dismantled, thus extending the construction period. Second, the handling and stacking of numerous counterweights not only increases labor costs but also poses certain safety risks. Therefore, existing suspended platform suspension mechanisms still need improvement in terms of roof space occupation, construction convenience, and cost. Utility Model Content

[0004] The purpose of this utility model is to provide a suspended platform suspension mechanism, which aims to solve the problems of existing suspended platform suspension mechanisms relying on roof counterweights, occupying a large amount of roof space, affecting subsequent construction, and having high costs and risks in transporting counterweights.

[0005] This utility model is achieved through the following technical solution:

[0006] A suspended platform suspension mechanism includes a lower bracket that can be fixed to the top of a parapet wall. The upper end of the lower bracket is detachably connected to a mounting beam. One side of the mounting beam is used to suspend the suspended platform, and the other side is connected to one end of a diagonal bracing mechanism. One end of the diagonal bracing mechanism can be fixed to the side of the parapet wall. An upper support column is vertically provided on the mounting beam corresponding to the lower bracket. The upper end of the upper support column is connected to a tensioning assembly. One end of the tensioning assembly is connected to the end of the mounting beam used to suspend the suspended platform, and the other end is connected to one end of the diagonal bracing mechanism.

[0007] As described above, in a suspended platform suspension mechanism, the lower support includes an A-frame, the bottom of which is welded with an installation base plate fixed to the top of the parapet wall, and the upper end of which is welded with a first installation part adapted to the installation beam.

[0008] In the suspended platform mechanism described above, the first mounting part is a channel steel that is adapted to the shape of the mounting beam and can be detachably connected to it.

[0009] As described above, in a suspended basket suspension mechanism, stiffening ribs are provided between the two sides of the channel steel and the A-frame.

[0010] As described above, a suspended basket suspension mechanism includes a first connecting member detachably connected to the mounting beam, one end of a diagonal brace is detachably connected to the first connecting member, and the other end of the diagonal brace is hinged to a second connecting member, which can be fixedly connected to the side of the parapet wall.

[0011] As described above, the suspended platform mechanism has multiple mounting holes on both sides of the mounting beam along its length. These mounting holes can be bolted to the first connecting member for adjustment.

[0012] In the suspended basket mechanism described above, the mounting hole can be bolted to the upper end of the lower bracket.

[0013] As described above, in a suspended platform suspension mechanism, the upper support includes a vertical pipe, and a second mounting part is welded to the lower end of the vertical pipe, which can be fixedly connected to the mounting beam and the lower bracket. The second mounting part is adapted to the shape of the mounting beam and can be bolted to the assembly hole. The upper end of the vertical pipe is connected to the tensioning assembly.

[0014] As described above, in a suspended platform suspension mechanism, the tensioning assembly includes a first tensioning member disposed on the mounting beam corresponding to the first connecting member. The first tensioning member is connected to a turnbuckle, and the turnbuckle is connected to one end of a steel cable. The upper end of the upper support column is provided with a rope wheel that is tumblingly connected to the steel cable. A second tensioning member is provided on one end of the mounting beam for suspending the suspended platform, and the second tensioning member is connected to the other end of the steel cable.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention changes the traditional suspended platform suspension mode by fixing the lower support to the top of the parapet wall, connecting the diagonal bracing mechanism to the installation beam and fixing it to the side of the parapet wall, and setting an upper support column and cooperating with the tensioning component to form a stable tensioning system on the installation beam. It eliminates the need to rely on a large-scale roof support structure and a large number of counterweights to provide anti-overturning force. This support method, based on the fixed parapet wall and the synergistic effect of structural components, maximizes the saving of valuable roof space, greatly facilitates subsequent roof construction, and improves overall construction efficiency. At the same time, by avoiding the use of counterweights, it significantly reduces the labor intensity, cost, and related safety risks associated with material handling and transportation.

[0023] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0024] Suspended platforms, as a type of construction machinery used for working at heights, are widely used in modern construction projects, mainly for tasks such as curtain wall installation, exterior wall cleaning, insulation construction, and maintenance. Their advantages include replacing traditional scaffolding, significantly reducing labor intensity, improving work efficiency, and being reusable. However, existing standard suspended platform suspension mechanisms, especially those relying on counterweights for overturning prevention, typically require the erection of massive support structures and the stacking of numerous counterweights on the building's roof. This method not only occupies valuable roof space and causes numerous inconveniences and impacts on subsequent roof construction, such as the installation of waterproofing and insulation layers, but sometimes even necessitates roof repairs only after the suspended platform is dismantled, extending the construction period. Furthermore, the handling and stacking of large quantities of counterweights increases labor costs and safety risks.

[0025] To address the above problems, this embodiment provides a novel suspended platform suspension mechanism, designed to reduce or eliminate the occupation of roof space while ensuring the stability and safety of the mechanism. Please refer to the attached document. Figures 1 to 4 The suspended platform suspension mechanism of this embodiment includes a lower support 1 that can be fixed to the top of the parapet wall. The upper end of the lower support 1 is detachably connected to an installation beam 2. One side of the installation beam 2 is used to suspend the suspended platform, and the other side is connected to one end of a diagonal bracing mechanism 3. One end of the diagonal bracing mechanism 3 can be fixed to the side of the parapet wall. An upper support column 4 is vertically provided on the installation beam 2 corresponding to the lower support 1. The upper end of the upper support column 4 is connected to a tensioning component 5. One end of the tensioning component 5 is connected to the end of the installation beam 2 used to suspend the suspended platform, and the other end is connected to one end of the diagonal bracing mechanism 3.

[0026] In this embodiment, the lower support 1 is the main connecting and load-bearing component between the mechanism and the top of the parapet wall, designed to be firmly fixed to the top horizontal surface of the parapet wall. The main body of the lower support 1 is welded or assembled from high-strength structural steel, and its structure can be a compact base plate with columns or a frame structure to maximize the contact area with the top of the parapet wall 6 and evenly transfer the load. Its bottom has pre-drilled anchoring holes, which are reliably anchored to the concrete or brick-concrete structure at the top of the parapet wall using high-strength chemical bolts, mechanical expansion bolts, or through-wall bolts. The upper part of the lower support 1 has an interface for detachable connection with the installation beam 2, for example, a connecting lug formed by welding thick steel plates, which is connected with high-strength bolts. The installation beam 2 is the main beam that bears the weight of the suspended platform and extends outward. It is detachably connected to the upper end of the lower support 1 and extends a certain distance outward from the building. One side of this extended portion, which is the side used to suspend the suspended platform, has a suspension point for connecting the working steel wire rope and safety steel wire rope of the suspended platform. Mounting beam 2 can be made of high-strength rectangular steel pipe or specially shaped steel pipe to provide sufficient bending and torsional stiffness. A diagonal bracing mechanism 3 is connected to the other side of mounting beam 2, closer to the building.

[0027] The diagonal bracing mechanism 3 provides vertical and lateral support and stability for the mounting beam 2. One end is connected to the side of the mounting beam 2 closest to the building, while the other end can be fixed to the side surface of the parapet wall 6. The diagonal bracing mechanism 3 can be constructed from one or more high-strength steel pipes or solid steel rods to form a diagonal tension or bracing structure. The end fixed to the side of the parapet wall 6 employs a reliable anchoring method, such as selecting appropriate anchors, rebar, or a custom-made clamp structure depending on the material of the parapet wall 6 sidewall.

[0028] It should be noted that the connection between the diagonal bracing mechanism 3 and the mounting beam 2 can be either hinged or rigid, depending on the required support characteristics. By setting the support point at a lower position on the side of the parapet wall 6, the diagonal bracing mechanism 3 can effectively convert part of the vertical load on the mounting beam 2 and most of the overturning moment generated by the overhang into pressure or tension on the side of the parapet wall 6, significantly improving the overturning stability of the structure.

[0029] The upper support column 4 is vertically mounted on the mounting beam 2, preferably at or near the connection point between the mounting beam 2 and the lower support 1. The upper support column 4 is made of steel pipe or structural steel and can be fixed to the upper surface of the mounting beam 2 by welding or other high-strength connection methods. The upper support column 4 acts as a lifting point, providing vertical support for the tensioning assembly 5, thereby optimizing the stress angle of the tensioning assembly 5. The upper end of the upper support column 4 has a structure for connecting the tensioning assembly 5, such as a pin hole or a connecting plate.

[0030] The tensioning assembly 5 connects the upper end of the upper support column 4, the end of the mounting beam 2 used to suspend the suspended platform (near the outer suspension point), and the end of the diagonal bracing mechanism 3 fixed near the side of the parapet wall 6. The tensioning assembly 5 can be composed of high-strength steel wire rope, adjusting rods, or assemblies, and can be used in conjunction with adjusting bolts. By adjusting the length and tension of the tensioning assembly 5, a pre-tension can be applied to the mounting beam 2 after the mechanism is installed, effectively controlling the bending moment and deflection of the mounting beam 2 when bearing the load of the suspended platform. The tensioning assembly 5 guides the tension at the front end of the mounting beam, generated by the load of the suspended platform, through the upper support column 4 to the fixed point of the diagonal bracing mechanism 3, forming a stable triangular or polygonal support system. This greatly enhances the overall rigidity and stability of the structure and reduces the requirement for the bending resistance of the mounting beam itself.

[0031] Compared to existing technologies, the suspended platform suspension mechanism in this embodiment is mainly fixed to the top and sides of the parapet wall 6. The lower support structure is compact, eliminating the need for extensive roof support structures and the stacking of numerous counterweights, thus maximizing the use of roof space. Since it does not occupy the main roof area, subsequent construction work such as waterproofing and insulation can proceed more smoothly without waiting for the suspended platform to be dismantled, shortening the construction period and reducing the risk of mutual interference. Furthermore, the avoidance of counterweights reduces the labor intensity and transportation costs associated with material handling and stacking, and the adjustability of the entire structure allows it to adapt to parapet walls of different heights and construction methods.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the lower support 1 includes an A-frame 11, a mounting base plate 12 welded to the bottom of the A-frame, and a first mounting part 13 welded to the upper end of the A-frame and adapted to the mounting beam.

[0033] Specifically, the A-frame 11 constitutes the main load-bearing skeleton of the lower support 1, typically welded from high-strength steel to form an A-shaped structure with good stability. The downward-opening bottom of the A-frame 11 is firmly welded to the mounting base plate 12. The mounting base plate 12 is a flat or reinforced steel plate that directly contacts the top surface of the parapet wall 6 and has pre-drilled holes for anchoring. The entire lower support 1 is securely fixed to the top of the parapet wall 6 using reliable anchors such as high-strength chemical bolts or expansion bolts. In this way, the load of the A-frame 11 is evenly and effectively transferred to the parapet wall structure through the large area of ​​the mounting base plate 12. Meanwhile, the first mounting part 13 is welded to the upward-converging upper end of the A-frame 11. The first mounting part 13 is a component specifically designed to cooperate with the connection structure of the mounting beam 2, for example, it can be a pair of connecting lugs with bolt holes, providing a precise and high-strength mating point for the mounting beam 2, realizing a convenient and reliable detachable connection between the mounting beam 2 and the lower support 1.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the first mounting part 13 is specifically a channel steel. The shape and size of the channel steel are designed to match the external dimensions of the mounting beam 2. For example, if the mounting beam 2 is a rectangular steel pipe, the first mounting part 13 can be an upward-opening channel steel, whose internal U-shaped groove can accommodate the bottom or top of the mounting beam 2, and the two can be detachably connected through bolt holes provided on the side wall of the channel steel and the mounting beam 2.

[0035] To enhance the connection strength and overall rigidity between the first mounting part 13 and the A-frame 11, and to prevent deformation or failure of the connection under high loads, stiffening ribs 14 are welded to the corresponding connection points of the A-frame 11 on both sides of the channel steel, i.e., the web or flange of the channel steel. These stiffening ribs 14 can be triangular or trapezoidal steel plates, welded perpendicular to the surfaces of the channel steel and the A-frame, forming a reinforced support. This effectively distributes the load transmitted by the mounting beam 2 through the first mounting part 13 more evenly to the main structure of the A-frame 11, further improving the overall load-bearing capacity and stability of the lower support 1.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the diagonal bracing mechanism 3 includes a first connecting member 31 detachably connected to the mounting beam 2. One end of the first connecting member 31 is detachably connected to the diagonal bracing rod 32, and the other end of the diagonal bracing rod 32 is hinged to a second connecting member 33. The second connecting member 33 can be fixedly connected to the side of the parapet wall 6.

[0037] Specifically, the first connecting member 31 is detachably connected to the side of the mounting beam 2 away from the suspended basket. The first connecting member 31 may be a lug, pin seat, or other connecting component welded or bolted to the side of the mounting beam 2, and is designed for quick and reliable detachable connection to one end of the diagonal brace 32.

[0038] The diagonal brace 32 is a main diagonal support component, which can be made of high-strength steel pipe or solid round steel. Its length can be adjusted or different lengths of rods can be selected according to actual needs. One end of the diagonal brace 32 is detachably connected to the first connecting member 31. This detachable design allows the diagonal brace 32 to be easily connected or separated from the mounting beam 2, facilitating the installation, disassembly, and transportation of the mechanism.

[0039] The other end of the diagonal brace 32 is hinged to the second connecting member 33. This hinged connection allows the diagonal brace 32 to rotate within a certain range relative to the second connecting member 33. This design effectively absorbs installation errors that may occur during installation and allows for minor angular adjustments under stress, avoiding harmful constraint stresses. The hinged structure consists of a pin and a pin hole.

[0040] The second connector 33 is designed for fixed connection to the side of the parapet wall 6. Its structural form depends on the specific material and construction of the side of the parapet wall 6; it can be a steel plate with anchoring holes for anchoring with chemical bolts or expansion bolts, a U-shaped clamp structure for gripping the edge of the parapet wall 6, or other custom-made connectors. The second connector 33 securely anchors the lower end of the diagonal bracing mechanism 3 to the side wall of the parapet wall 6, thereby transferring the load to the parapet wall structure.

[0041] In the entire suspended platform suspension mechanism, the diagonal bracing mechanism 3 is connected to the mounting beam 2 via the first connecting member 31, and the force is transmitted to the second connecting member 33, which is fixed to the side of the parapet wall, via the diagonal bracing rod 32. This segmented, detachable diagonal bracing mechanism 3 design with hinged points not only facilitates on-site assembly and adjustment and improves adaptability to different parapet wall structures and installation conditions, but also effectively provides diagonal support force to the mounting beam 2 through the supporting action of the diagonal bracing rod 32, sharing the vertical load and overturning moment, and enhancing the overall stability and safety of the mechanism. At the same time, setting the support point on the side of the parapet wall further reduces the dependence on the main roof space.

[0042] Furthermore, to improve the installation flexibility and adjustability of the suspended platform mechanism, multiple linearly arranged mounting holes 21 are provided on both sides of the mounting beam 2 along its length. These mounting holes 21 are precisely machined in advance on the sidewalls of the mounting beam 2, and their spacing and size are determined according to connection requirements. These mounting holes 21 have important connection functions. On the one hand, the mounting holes 21 can be used for bolt connection with the first connecting member 31 of the diagonal bracing mechanism 3. Due to the multiple holes along the length direction, the first connecting member 31 can be bolted to different positions on the side of the mounting beam 2, thereby facilitating the adjustment of the connection point between the diagonal bracing mechanism 3 and the mounting beam 2, and thus changing the angle and span of the diagonal bracing rod 32 to adapt to different parapet wall heights and required overhang distances, or to optimize the stress state. This multi-hole design greatly enhances the ease of adjusting the installation position of the diagonal bracing mechanism 3.

[0043] On the other hand, the mounting holes 21 can also be used for bolt connection with the upper end of the lower bracket 1, i.e., the first mounting part 13. This means that when the channel steel structure of the first mounting part 13 is connected to the mounting beam 2, the bolt holes or connecting structures on its side wall will align with one or more sets of these mounting holes 21 on the side of the mounting beam 2, and the two can be detachably connected by bolts. This design allows the specific positioning of the mounting beam 2 on the lower bracket 1 to be finely adjusted within a certain range, for example, to achieve switching between different cantilever distances.

[0044] Furthermore, the upper support column 4 includes a riser 41 and a second mounting part 42. Specifically, the riser 41 is the main body of the upper support column 4 and can be made of high-strength steel pipe, with its height determined according to the connection requirements of the tensioning assembly 5. The lower end of the riser 41 is welded with the second mounting part 42. The second mounting part 42 is a key component for connecting the upper support column 4 with the mounting beam 2 and the lower support 1. The shape of the second mounting part 42 is designed to fit the shape of the mounting beam 2, for example, it can be a base plate or a U-shaped groove seat, on which bolt holes corresponding to the assembly holes 21 on both sides of the mounting beam 2 are machined. By placing the second mounting part 42 on the mounting beam 2 and using high-strength bolts passing through the holes of the second mounting part 42 and the assembly holes 21 of the mounting beam 2, a reliable connection between the upper support column 4 and the mounting beam 2 is achieved. Meanwhile, since the upper support column 4 is usually located in the connection area corresponding to the mounting beam 2 and the lower bracket 1, the design of the second mounting part 42 also takes into account the cooperation with the upper end of the lower bracket 1. This ensures that when the upper support column 4 is fixed to the mounting beam 2 through the assembly hole 21, it can also form a stable fixed connection with the lower bracket 1 in this connection area, sharing and transmitting the load together. This method of fixing the upper support column 4 by bolting it to the assembly hole 21 of the mounting beam 2 simplifies the installation process and makes full use of the existing connection holes on the mounting beam 2.

[0045] Furthermore, the tensioning assembly 5 employs a structure of steel cable, tensioning member, and rope pulley to provide effective tension support. Specifically, the tensioning assembly 5 includes a first tensioning member 51 located on the mounting beam 2 near the first connecting member 31 of the diagonal bracing mechanism 3.

[0046] The first fastener 51 is a fixed end of the steel cable 52. Its structure can be a lug, annular seat, or other structure welded or bolted to the mounting beam 2 to reliably anchor one end of the steel cable 52. Its position is preferably near the connection point between the diagonal bracing mechanism 3 and the mounting beam 2 to create a favorable stress geometry. The first fastener 51 is connected to a turnbuckle 55, which is connected to one end of the steel cable 52. By providing a turnbuckle 55 between the first fastener 51 and the steel cable 52, the effective length of the steel cable 52 can be easily adjusted, thereby precisely controlling and applying the required preload to optimize the stress state of the mounting beam 2 and the overall structural stiffness.

[0047] After the steel cable 52 emerges from the turnbuckle 55, it winds upwards around the pulley 53 located at the upper end of the upper support column 4. The pulley 53 is mounted on the top of the upper support column 4 and connected to it via a pin or other rotatable connection, forming rolling contact with the steel cable 52. The pulley 53 acts as a guide component, deflecting the tension of the steel cable 52, allowing the tension to be transmitted through the upper support column 4 to the mounting beam 2 and the lower support 1.

[0048] After the steel cable 52 passes over the sheave 53, its other end is connected downwards to a second fastener 54 located on the mounting beam 2 for suspending one end of the suspended platform. The second fastener 54 is the other fixed end of the steel cable 52, and its structure can also be a welded or bolted ear plate, annular seat, or anchoring device near the outer end of the mounting beam 2, ensuring a reliable connection to the other end of the steel cable 52. The second fastener 54 is preferably located near the suspension point of the suspended platform to effectively provide upward support against the bending moment generated by the load on the suspended platform.

[0049] By using the tensioning assembly 5, which consists of a first tensioning member 51 connecting turnbuckle 55, a steel cable 52, a rope pulley 53, and a second tensioning member 54, this embodiment can establish a precisely adjustable tension force on the mounting beam 2. This tension force, through the reaction of the upper support column 4, effectively counteracts the downward deflection tendency of the mounting beam 2, significantly improving the load-bearing capacity of the mounting beam 2 and the overall rigidity of the structure.

[0050] Working principle of this utility model:

[0051] This embodiment provides a suspended platform suspension mechanism that solves the problem of traditional suspended platform suspension mechanisms relying on large roof counterweights and occupying space. Its core principle lies in anchoring the structure to the top and sides of the parapet wall to provide support and stability. Specifically, the lower support is firmly fixed to the top of the parapet wall as a basic support; the mounting beam extends from here to suspend the suspended platform. To counteract the overturning moment generated by the outward extension of the mounting beam, the structure introduces a diagonal bracing mechanism, with one end connected to the mounting beam and the other end reliably fixed to the side of the parapet wall, providing strong diagonal support. Furthermore, by setting up an upper support column and connecting tensioning components, a triangular or polygonal tensioning system is formed. This system applies pre-tension to the mounting beam, further enhancing the overall stiffness and stability of the structure, effectively distributing the load, thus eliminating the need for roof counterweights, significantly freeing up roof space, and improving construction efficiency.

[0052] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
