Description

Technical Field

[0001] The invention belongs to the technical field of bridge construction, and in particular relates to a safety protection platform for a hanging basket to be transversely connected to a truss. Background Art

[0002] There are hangers at both ends of the hanging basket's transverse connecting trusses for adjusting the bottom basket elevation. The frequency of adjustment of the hangers here is relatively low. In order to save costs, most construction methods currently require workers to climb directly from the unprotected hanging basket bracket to the end of the transverse connecting truss to adjust the hangers. This method poses a huge safety hazard.

[0003] In addition, the existing hanging basket transversely connected truss platform generally includes a bracket, a walking board, and a guardrail. The bracket is connected to the crossbeam by bolts, the walking board is placed on the bracket and welded to the bracket, and steel bars are welded to the side of the walking board as a guardrail, or the guardrail is connected to the walking board with bolts. This method has the following disadvantages:

[0004] 1. The walking board and the bracket are generally fixed by on-site welding. Multiple welding and disassembly increase the loss rate of the hanging basket protection system.

[0005] 2. The bolts on the side of the walking board are exposed, which can cause interference between the walking board, brackets, and crossbeams. Interference areas must be welded. This method results in heavy on-site installation and disassembly work, high labor intensity, and difficulty in high-altitude operations. Furthermore, the hanging basket is prone to deformation after multiple disassembly and welding, resulting in high product damage and scrap rates and poor appearance.

[0006] 3. The connecting flange between the walking boards is located below the walking boards. High-altitude operations make bolt connection difficult, so on-site workers basically use welding to connect the walking boards.

[0007] 4. To build the guardrail, one needs to climb to the top of the horizontal connecting truss to weld the steel bars on site. In addition, the horizontal bars are built after the vertical bars are installed, and cross fasteners are used to connect the horizontal bars to the vertical bars. This operation method has a greater safety risk and poor appearance. Summary of the Invention

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] 1. The safety protection platform for the transverse connecting truss of the hanging basket of the present invention forms a safety protection system with a simple structure and reliability through the cantilever bracket assembly, the walking board assembly, the guardrail assembly and the climbing ladder assembly; the cantilever bracket assembly is detachably connected to the transverse connecting truss of the hanging basket, and the walking board assembly is laid on the cantilever bracket assembly in a detachable form, so that the walking board assembly is hung on the transverse connecting truss of the hanging basket; the guardrail assembly is fixed to the walking board assembly, so that the transverse connecting truss of the hanging basket is safely protected; and the climbing ladder assembly is then connected to the walking board assembly, so that workers can climb from the bridge surface to the safety protection platform, which has the advantages of easy installation and disassembly, high reuse rate, low cost, high safety, and strong versatility, ensuring the safety of high-altitude operations, and also eliminating the safety risks caused by workers directly climbing from the unprotected hanging basket bracket to the end adjustment boom of the transverse connecting truss.

[0024] 2. The safety protection platform for the transverse connecting truss of the hanging basket in the preferred example of the present invention realizes the bolt connection between the cantilever bracket and the transverse connecting truss of the hanging basket by means of the mounting plate arranged at the end of the load-bearing plate; the walking board assembly is laid on the load-bearing plate, and the load-bearing plate is used to bear the weight load of the safety protection platform, which is safe and reliable; and the locking clamps and the limit plates arranged at the opposite ends of the load-bearing plate cooperate with each other to realize the longitudinal, transverse and vertical positioning and locking of the walking board assembly, thereby improving the installation stability of the walking board assembly; the cantilever bracket has a simple structure, does not require welding or a large number of bolts, and is convenient and quick to install and dismantle, thereby improving the reliability of the safety protection system while also reducing the installation workload of the safety protection system.

[0025] 3. In a preferred embodiment of the present invention, a safety protection platform for connecting a hanging basket to a truss is provided with a rectangular tube on both sides of the tread, and connecting holes are provided at both ends of the rectangular tube, thereby enabling bolt connection between adjacent treads, while also allowing the bolt assembly to be hidden within the rectangular tube. Furthermore, the rectangular tube is provided with a plurality of side holes, and the tread is provided with a plurality of mounting holes. The side holes and the mounting holes correspond to each other, thereby enabling bolt connection between the guardrail assembly and the tread, and the bolt assembly can be hidden within the rectangular tube. The provision of the rectangular tube prevents the bolt assembly from contacting external objects during transportation, hoisting, and stacking of the walking board assembly, making the bolt assembly less susceptible to damage and deformation, thereby increasing the service life and reuse rate of the bolt assembly. Furthermore, the internal structure of the bolt assembly ensures that the walking board assembly has a uniform profile in any cross-section, without any protruding structures, and does not interfere structurally with the locking clamps and limit plates.

[0043] Example 1

[0044] like Figures 1 to 4 、 Figures 6 to 11 As shown, the safety protection platform for the hanging basket transverse connection truss of the present invention includes: a cantilever support assembly 1, a walking board assembly 2, a guardrail assembly 3 and a ladder assembly 4. One end of the cantilever support assembly 1 is detachably connected to the transverse connection truss 5 of the hanging basket by a bolt assembly, and a walking board assembly 2 is detachably laid on the cantilever support assembly 1, and the cantilever support assembly 1 is used to realize that the walking board assembly 2 is suspended on the transverse connection truss 5. The guardrail assembly 3 is connected to the walking board assembly 2 for realizing safety protection. The ladder assembly 4 is connected to the walking board assembly 2 for realizing that the staff climbs from the bridge surface to the safety protection platform. The connection structure of the safety protection platform and the hanging basket transverse connection truss is shown in FIG. Figure 3 It can be understood that the safety protection platform of this embodiment is mainly installed at the end of the transverse connecting truss 5 for adjusting the boom.

[0045] In this embodiment, a safety protection system with a simple structure and reliability is formed by the cantilever support assembly 1, the walking board assembly 2, the guardrail assembly 3 and the ladder assembly 4; the cantilever support assembly 1 is detachably connected to the transverse connecting truss 5 of the hanging basket, and the walking board assembly 2 is detachably laid on the cantilever support assembly 1, so that the walking board assembly 2 is suspended on the transverse connecting truss 5 of the hanging basket; the guardrail assembly 3 is fixed to the walking board assembly 2, so that the transverse connecting truss 5 of the hanging basket is safely protected; and the ladder assembly 4 is connected to the walking board assembly 2, so that the staff can climb from the bridge surface to the safety protection platform, which has the advantages of easy installation and disassembly, high reuse rate, low cost, high safety, and strong versatility, ensuring the safety of high-altitude operations, and also eliminating the safety risks caused by the staff directly climbing from the unprotected hanging basket support to the end of the transverse connecting truss to adjust the boom.

[0046] like Figure 4As shown, in this embodiment, the cantilever support assembly 1 includes a first cantilever support 11 of a T-shaped structure, and the first cantilever support 11 includes: a first mounting plate 111, a first load-bearing plate 113 and a first limit plate 114. One end of the first load-bearing plate 113 is welded to the first mounting plate 111, and the other end of the first load-bearing plate 113 is welded to the first limit plate 114; bolt connection holes are provided at both ends of the first mounting plate 111, for realizing bolt connection between the first cantilever support 11 and the transverse connecting truss 5; the walking plate assembly 2 is detachably laid on the first load-bearing plate 113, and a groove is provided on the upper part of the first limit plate 114, and the first limit plate 114 can limit the longitudinal and vertical displacement of the walking plate assembly 2. It can be understood that in order to improve the load-bearing capacity of the cantilever support assembly 1, the first load-bearing plate 113 can be prepared using steel sections.

[0047] In this embodiment, the first cantilever bracket 11 further includes a first locking fixture 112 connected to the first bearing plate 113. The first locking fixture 112 and the first bearing plate 113 can be removably connected using a bolt assembly. The first locking fixture 112 is located between the first mounting plate 111 and the first limiting plate 114, and is located on a side proximal to the first mounting plate 111. Specifically, the first locking fixture 112 and the first limiting plate 114 are located on opposite sides of the first bearing plate 113. The first locking fixture 112 and the first limiting plate 114 cooperate with each other to respectively lock the two sides of the walking board assembly 2, thereby securing the walking board assembly 2 to the first bearing plate 113 and improving the installation stability of the walking board assembly 2. It is understood that the specific placement of the first locking fixture 112 and the first limiting plate 114 on the first bearing plate 113 is not particularly limited, as long as they can effectively secure the two sides of the walking board assembly 2.

[0048] Furthermore, the first locking fixture 112 includes a first adjusting screw assembly 115 . By screwing the first adjusting screw assembly 115 , the walking board assembly 2 can be well locked in the longitudinal and transverse directions.

[0049] In this embodiment, a bolt connection is achieved between the first cantilever bracket 11 and the transverse connecting truss 5 by setting a first mounting plate 111 at the end of the first bearing plate 113; the walking board assembly 2 is laid on the first bearing plate 113, and the first bearing plate 113 is used to bear the weight of the safety protection platform, which is safe and reliable. Then, by the mutual cooperation between the first locking clamp 112 and the first limiting plate 114 set at the opposite ends of the first bearing plate 113, the walking board assembly 2 is positioned and locked in the longitudinal, transverse and vertical directions, thereby improving the installation stability of the walking board assembly 2. The first cantilever bracket 11 of this embodiment has a simple structure and does not require welding or a large number of bolts. It is easy and quick to install and remove, which improves the reliability of the safety protection platform while also reducing the installation workload of the safety protection platform.

[0050] like Figures 6 to 9 As shown, in this embodiment, the walking board assembly 2 includes a rectangular tube 21 and a pedal 22. The rectangular tube 21 is disposed on both sides of the pedal 22 along its length. First connection holes 212 are defined at both ends of the rectangular tube 21. The first connection holes 212 are used to detachably connect adjacent pedals 22. Specifically, adjacent pedals 22 are connected by bolt assemblies via the first connection holes 212 disposed at the ends of the rectangular tube 21. The bolt assemblies are placed within the first connection holes 212 and do not need to be exposed.

[0051] Furthermore, a plurality of side holes 211 are provided on the rectangular tube 21, and a plurality of mounting holes 221 are correspondingly provided on the pedal 22. The side holes 211 correspond to the mounting holes 221 one by one and are used to realize the bolt connection between the guardrail assembly 3 and the pedal 22, and the bolt assembly is hidden in the side hole 211 and does not need to be exposed.

[0052] In this embodiment, by providing rectangular tubes 21 on both sides of the pedals 22 and opening connecting holes at both ends of the rectangular tubes 21, bolt connection between adjacent pedals is achieved, and the bolt assembly can be hidden in the rectangular plate; further, a plurality of side holes 211 are provided on the rectangular tube 21, and a plurality of mounting holes 221 are provided on the pedals 22. The side holes 211 and the mounting holes 221 correspond to each other, so that the guardrail assembly 3 and the pedals 22 are bolted together, and the bolt assembly can be hidden in the rectangular tube 21; the provision of the rectangular tube 21 prevents the bolt assembly from contacting with external objects during transportation, hoisting, and stacking of the walking board assembly 2, so that The bolt assembly is not easily damaged or deformed, thereby increasing the service life and reuse rate of the bolt assembly; further, the built-in structure of the bolt assembly allows the walking board assembly 2 to have the same external contour in any cross-section, without any protruding structure, and does not structurally interfere with the second locking clamp 124 and the second limit plate 125. Therefore, the walking board assembly 2 can be installed at any position on the cantilever bracket assembly 1, which greatly facilitates the operation of on-site workers and avoids the on-site cutting and modification of components by workers due to structural interference, greatly extending the service life of the components, being more conducive to repeated turnover, and significantly improving economic benefits.

[0053] like Figure 10 and Figure 11 As shown, in this embodiment, the guardrail assembly 3 includes an end guardrail 31 and a middle guardrail 32 used in combination. Figure 11 Figures (a), (b), (c), (d), and (e) illustrate five different combinations of end guardrails 31 and intermediate guardrails 32. These combinations can be flexibly tailored to meet the specific needs of different hanging basket installations. Furthermore, bolt assemblies secure adjacent intermediate guardrails 32, or between end guardrails 31 and intermediate guardrails 32, significantly improving the overall lateral stability of the guardrail assembly 3 and enhancing the safety of the guardrail system.

[0054] In this embodiment, the end guardrail 31 comprises a guardrail body 311, a kickboard 312, and legs 313. The guardrail body 311 can be welded from steel pipes. The kickboard 312 and legs 313 are both located below the guardrail body 311. The kickboard 312 is used to prevent workers from accidentally stepping on empty space and objects placed on the walking board from falling. During guardrail installation, the legs 313 are inserted into the mounting holes 221 and bolt assemblies are installed in the side holes 211 to achieve a detachable connection between the end guardrail 31 and the pedal 22. The bolt assemblies can be concealed within the rectangular tube 21 and do not need to be exposed.

[0055] Furthermore, mounting lugs 3121 are provided on both sides of the skirting board 312, and second connecting holes 3122 are provided on the mounting lugs 3121. Figure 2As shown, when the end guardrail 31 is set at the end of the pedal 22, the second connection hole 3122 cooperates with the first connection hole 212, and the end guardrail 31 can be connected to the end of the pedal 22 by using a bolt assembly, which is simple and reliable.

[0056] It is understood that the middle guardrail 32 has a similar structure to the end guardrail 31. The middle guardrail 32 also includes a guardrail body, a kickboard, and a leg. The connection between the middle guardrail 32 and the pedal 22 is also similar to that of the end guardrail 31. To further expand the applicability of the guardrail assembly, the middle guardrail 32 can be provided in different lengths, such as 1m, 2m, or 3m.

[0057] In this embodiment, by providing a support leg 313 at the bottom of the end guardrail 31, inserting the support leg 313 into the mounting hole 221 on the pedal 22, and then tightening it with a bolt assembly, a secure connection between the end guardrail 31 and the pedal 22 is achieved. The bolt assembly can also be hidden within the rectangular tube 21 on the side of the pedal 22, making it both stable and aesthetically pleasing. By providing a kickboard 312 at the bottom of the end guardrail 21, it effectively prevents people from accidentally stepping on empty space. At the same time, mounting lugs 3121 with connection holes are provided on both sides of the kickboard 312. When the end guardrail 31 is installed at the end of the pedal 22, the mounting lugs 3121 can connect with the connection holes at the end of the pedal, thereby increasing the flexibility of the guardrail assembly. Furthermore, by combining the intermediate guardrail with the end guardrail, the guardrail gap can be set at any position on the horizontal connecting truss of the hanging basket to meet the installation requirements of ladders in different locations, increasing the versatility of the guardrail components and greatly broadening the scope of application of the guardrail assembly.

[0058] like Figure 1 As shown, in this embodiment, the ladder assembly 4 includes a ladder guardrail 41 and a ladder 43. The ladder guardrail 41 is an arched structure, and the ladder guardrail 41 is welded and fixed to the ladder 43, and the arched channel surrounded by the ladder guardrail 41 surrounds the outside of the ladder 43. The lower part of the ladder 43 is located on the bridge surface, that is, the lower part of the ladder 43 can be connected to the bridge surface, or it can be suspended on the bridge surface, as long as it can meet the climbing needs of the staff; the upper part of the ladder 43 is provided with a connecting hole, and the connecting hole can be bolted to the first connecting hole 212 at the end of the pedal 22 to achieve the fixation of the ladder. Furthermore, in order to improve the safety of the ladder assembly 4, a reinforcing rod 42 is provided on the outside of the ladder guardrail 41 in the vertical direction.

[0059] In this embodiment, by fixing the arched ladder guardrail on the ladder, an arched passage is formed on the outside of the ladder, which solves the problem of low safety factor of the ladder and ensures the safety of on-site construction; by detachably connecting the upper part of the ladder to the walking board assembly, the amount of welding on the construction site is reduced and the flexibility of use of the ladder assembly is improved; further, based on cost savings and the low frequency of use of the horizontally connected truss platform, a lower-cost vertical ladder is adopted, which is conducive to reducing the cost of building a safety protection platform.

[0060] The safety protection platform of this embodiment is installed as follows: first, the cantilever support assembly 1 is fixedly connected to the transverse connecting truss 5, and then the walking board assembly 2 is laid on the first load-bearing plate 113 of the cantilever support. After the walking board assembly 2 is laid, the walking board assembly 2 is locked and fixed using the first locking clamp 112, and finally the guardrail assembly 3 is installed. This installation method is simple to operate and requires little experience from the construction personnel. The modularization of components eliminates the need for separate welding and cutting between components, greatly reducing the installation workload of the safety protection platform and improving the assembly efficiency of the hanging basket. Moreover, the above components are universally usable after installation, reducing the number of components and facilitating storage and transportation during recycling. The reduction in the number of components can also significantly reduce maintenance and service costs.

[0061] Example 2

[0062] like Figures 1 to 3 、 Figures 5 to 11 As shown, the safety protection platform for the transverse connection truss of the hanging basket of the present invention has a similar structural arrangement to the safety protection platform of Example 1, differing primarily in that: in this embodiment, the cantilever support assembly 1 includes an L-shaped second cantilever support 12, which comprises a second mounting plate 121, a U-shaped clip 122, a second bearing plate 123, and a second limit plate 125. The second bearing plate 123 is L-shaped. One end of the second bearing plate 123 is welded to the second mounting plate 121, and the other end of the second bearing plate 123 is welded to the second limit plate 125. Bolt holes are provided at both ends of the second mounting plate 121, and the opening of the U-shaped clip 122 is connected to the mounting plate via a bolt assembly, thereby enabling the second cantilever support 12 to be detachably connected to the horizontal rod of the transverse connection truss 5. A walking plate assembly 2 is detachably placed on the second bearing plate 123, and a groove is provided on the upper portion of the second limit plate 125 to limit the longitudinal and vertical displacement of the walking plate assembly 2. It can be understood that in order to improve the load-bearing capacity of the cantilever support assembly 1, the second load-bearing plate 123 can be made of steel.

[0063] In this embodiment, the second cantilever bracket 12 further includes a second locking fixture 124 connected to the second bearing plate 123. The second locking fixture 124 and the second bearing plate 123 can be detachably connected using a bolt assembly. The second locking fixture 124 and the second limiting plate 125 are arranged on both sides of the bottom of the second bearing plate 123 relative to each other. The second locking fixture 124 and the second limiting plate 125 cooperate with each other to lock the two sides of the walking board assembly 2 respectively, so as to achieve the fixing of the walking board assembly 2 to the second bearing plate 123 and improve the installation stability of the walking board assembly 2. It is understood that the specific location of the second locking fixture 124 and the second limiting plate 125 on the second bearing plate 123 does not need to be particularly limited, as long as they can achieve the limiting and fixing of the two sides of the walking board assembly 2.
