Description

Technical Field

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

[0002] In municipal bridge construction, especially when working at heights or near edges, support platforms are commonly used to provide a stable and safe working surface for construction workers. These support platforms must not only ensure their own structural stability but also be equipped with comprehensive safety protection mechanisms to prevent workers from falling.

[0003] Currently, common protective mechanisms mainly consist of guardrails installed around the perimeter of a support platform. In actual installation, these guardrails are often prefabricated independent components that need to be hoisted and transported onto the support plate on-site before being fixed in place.

[0004] However, this modular installation method has significant drawbacks: guardrails typically have considerable weight and height, requiring workers to manually support them for extended periods while erecting and aligning them with the fixing holes. The lack of effective temporary support measures before the final fixing bolts and clips are fully tightened not only makes the installation process time-consuming, labor-intensive, and inefficient, but also makes the guardrails prone to tipping and swaying during the handover between support and tightening, posing a significant safety hazard to installers.

[0005] Therefore, this utility model proposes a municipal bridge construction support platform to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems existing in the construction support platform for municipal bridges, such as the lack of temporary fixed support during the installation of guardrails, easy tipping, lack of stability, and difficulty in quickly aligning and splicing multiple platforms, this utility model aims to provide a municipal bridge construction support platform with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a support platform for municipal bridge construction, including a support plate, a protective mechanism, and a folding mechanism. The protective mechanism includes vertical columns, horizontal columns, and multiple anti-slip blocks. The vertical columns are fixedly installed on both sides of the support plate along its length, the horizontal columns are fixedly connected to the top of the vertical columns, and multiple anti-slip blocks are arranged in an array on the upper surface of the support plate.

[0008] The folding mechanism includes a guardrail, a connecting plate, a rotating column, a hook, and a fixing component. One end of the connecting plate is rotatably connected to the outer side of the support plate along its length, and the other end of the connecting plate is fixedly connected to the guardrail, allowing the guardrail to rotate around an axis to achieve folding and unfolding.

[0009] The rotating column is rotatably installed in the groove of the guardrail, and the hook is fixedly connected to the rotating column. The hook is used to detachably engage the vertical column of the guardrail mechanism during the erection of the guardrail, so as to provide temporary support and positioning for the guardrail.

[0010] Furthermore, the fixing components are used to securely fix the bottom of the guardrail to the corresponding holes in the support plate. This structural combination enables a complete installation process for the guardrail, from its rotatable, stowed state to its temporary snap-fit ​​support, and finally to its secure bolt fixing.

[0011] Preferably, the fixing component includes a fixing block and bolts. The fixing block is fixedly installed at the bottom of the guardrail, and the bolts pass through the fixing block and are threaded into the holes of the support plate. The guardrail is stably supported by tightening the bolts.

[0012] Preferably, the front end of the support plate is fixedly connected to a splicing upper plate, and the rear end of the support plate is fixedly connected to a splicing lower plate. This design enables the support plate to have a modular splicing function, which can meet the needs of different construction widths and lengths.

[0013] Furthermore, the folding mechanism also includes fixed posts and circular holes. The fixed posts are disposed on the upper surface of the support plates, and the circular holes are disposed on the upper surface of the support plates and arranged in an array along the splicing direction of the support plates. When multiple support plates are spliced, the fixed posts slide into the circular holes of adjacent support plates for initial positioning and alignment between the platforms.

[0014] Preferably, the structure of the guardrail works in conjunction with the structure of the vertical and horizontal posts to form a protective barrier, providing continuous and reliable fall protection for construction workers.

[0015] As a specific connection method, the connecting plate is rotatably connected to the support plate through a bearing. The bearing is located on the side of the support plate, thereby ensuring the smoothness and reliability of the guardrail rotation.

[0016] Preferably, circular holes are provided on the upper surface of the support plate and arranged in an array along the splicing direction of the support plate to ensure the accuracy of positioning during splicing.

[0017] Preferably, the upper and lower splicing plates are initially positioned and connected by inserting the fixing columns and circular holes. This quick insertion and connection reduces the time for on-site alignment and connection, and improves construction efficiency.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problems of existing guardrails having no temporary fixed support, being easy to tip over, inconvenient to install, and having poor stability by setting a folding mechanism, which includes a rotatable guardrail, a hook for temporarily engaging the vertical post, and a fixing component for final stabilization. It achieves the effect of temporary fixation followed by stabilization, greatly improving the convenience and safety of installation.

[0019] 2. This utility model solves the problem of difficulty in quickly aligning and splicing multiple support platforms in the prior art by setting splicing upper and lower plates on the support plate and using the sliding insertion of fixing columns and circular holes. It realizes rapid splicing and initial stabilization between platforms, which is convenient for forming a large-area working platform.

[0020] 3. This utility model solves the problems of slippery platform surfaces, lack of safe rope attachment points, and insufficient comprehensive protection capabilities in the prior art by setting multiple anti-slip blocks on the upper surface of the support plate and connecting horizontal columns to the top of the vertical columns of the protective mechanism. It achieves dual protection effects of anti-slip and high-altitude fall prevention, significantly improving the overall safety of construction. Attached Figure Description

[0023] Example

[0024] Reference Figures 1 to 3 This utility model provides a municipal bridge construction support platform, which aims to solve the problems of cumbersome steps, poor stability, and difficulty in temporary fixation when installing guardrails in existing municipal bridge construction platforms.

[0025] like Figure 1As shown, the municipal bridge construction support platform includes a support plate 1, a protective mechanism 3, and a folding mechanism 2. Both the protective mechanism 3 and the folding mechanism 2 are mounted on the support plate 1. The support plate 1 provides a stable support platform for the construction workers. The protective mechanism 3 includes vertical columns 31, horizontal columns 32, and multiple anti-slip blocks 33. The vertical columns 31 are fixedly mounted on both sides of the support plate 1 along its length, and the horizontal columns 32 are fixedly connected to the top of the vertical columns 31. Multiple anti-slip blocks 33 are arranged in an array on the upper surface of the support plate 1. The folding mechanism 2 includes a guardrail 22, a connecting plate 21, and a rotating... The moving column 23, hook 29, and fixing component 24 are provided. One end of the connecting plate 21 is rotatably connected to the outer side of the support plate 1 along its length, and the other end of the connecting plate 21 is fixedly connected to the guardrail 22 to enable the guardrail 22 to rotate and fold. The rotating column 23 is rotatably set in the groove of the guardrail 22. The hook 29 is fixedly connected to the rotating column 23 and is used to detachably engage the vertical column 31 of the protective mechanism 3 to temporarily support the vertical state of the guardrail 22. The fixing component 24 is used to firmly fix the bottom of the guardrail 22 to the corresponding hole of the support plate 1.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The folding mechanism 2 includes a connecting plate 21, a guardrail 22, a rotating column 23, a hook 29, and a fixing component 24. One end of the connecting plate 21 is rotatably connected to the outer side of the support plate 1 along its length, and the other end of the connecting plate 21 is fixedly connected to the guardrail 22. This arrangement allows the guardrail 22 to rotate around an axis for easy folding and installation. The rotating column 23 is rotatably disposed within a groove in the guardrail 22, and the hook 29 is fixedly connected to the rotating column 23. When installing the guardrail 22, rotating the hook 29 allows it to be detachably engaged with the vertical column 31 of the protective mechanism 3. This engagement structure provides temporary support for the guardrail 22 and maintains its upright position. The fixing component 24 is used to securely fix the guardrail 22 to the corresponding hole in the support plate 1 after it is erected. Specifically, as shown... Figure 2 As shown, the fixing component 24 includes a fixing block 241 and a bolt 242. The fixing block 241 is fixedly installed at the bottom of the guardrail 22, and the bolt 242 passes through the fixing block 241 and is threadedly connected to the hole of the support plate 1, thereby achieving the final stable fixing of the guardrail 22. This structure, which achieves rotation through the connecting plate 21, temporary snap-fit ​​through the hook 29, and stable fixing through the fixing component 24, ensures the convenience of the installation process and the final stability of the guardrail 22.

[0027] like Figure 2 As shown, the fixing component 24 includes a fixing block 241 and a bolt 242. The fixing block 241 is fixedly installed at the bottom of the guardrail 22, and the bolt 242 passes through the fixing block 241 and is threadedly connected to the hole of the supporting plate 1. Furthermore, a splicing upper plate 25 is fixedly connected to the front end of the supporting plate 1, and a splicing lower plate 26 is fixedly connected to the rear end of the supporting plate 1. Furthermore, the folding mechanism 2 also includes a fixing post 27 and a circular hole 28. The fixing post 27 is disposed on the upper surface of the support plate 1, and the circular hole 28 is disposed on the upper surface of the support plate 1 and arranged in an array along the splicing direction of the support plate 1. When multiple support plates 1 are spliced, the splicing upper plate 25 and the splicing lower plate 26 achieve preliminary positioning and connection through the insertion of the fixing post 27 and the circular hole 28. The fixing post 27 is slidably inserted into the circular hole 28. Preferably, the structure of the guardrail 22 cooperates with the structures of the vertical posts 31 and the horizontal posts 32 to jointly form the protective barrier of the protective mechanism 3. As a specific type of rotating connection, the connecting plate 21 is rotatably connected to the supporting plate 1 via a bearing, which is located on the side of the supporting plate 1.

[0028] The working principle is as follows: During installation, first rotate the guardrail 22 at the bottom of the support plate 1, so that the connecting plate 21 connected to the guardrail 22 rotates on the outside of the support plate 1 along the length direction through the bearing, thereby erecting the guardrail 22. Then rotate the hook 29, so that the rotating column 23 connected to the hook 29 rotates in the groove of the guardrail 22, thereby rotating the hook 29 to the outside of the vertical column 31 and detachably snapping it into the vertical column 31, temporarily supporting the guardrail 22 on the top of the support plate 1.

[0029] Next, using the fixing component 24, the bolts 242 in the fixing component 24 are inserted into the corresponding holes of the fixing block 241 at the bottom of the guardrail 22 and the support plate 1, and the bolts 242 are rotated to securely fix the guardrail 22 to the support plate 1.

[0030] When a splicing platform is required, the splicing upper plate 25 at the front end and the splicing lower plate 26 at the rear end of the support plate 1 cooperate with each other, so that the splicing lower plate 26 on the support plate 1 can be spliced ​​with the splicing upper plate 25 on the other support plate 1. When the splicing upper plate 25 and splicing lower plate 26 are spliced ​​and installed, the fixing column 27 also slides into the circular hole 28 of the other support plate 1 along with the splicing of the support plate 1, so as to carry out the initial splicing and installation of the support plate 1.

[0031] During use, the protective mechanism 3 provides safety protection. Multiple anti-slip blocks 33 on the upper surface of the support plate 1 are arranged in an array to prevent construction workers from slipping. Horizontal columns 32 are connected to the vertical columns 31 on both sides of the support plate 1 and are fixedly connected to the top of the vertical columns 31, allowing construction workers to fasten safety ropes to the horizontal columns 32, further ensuring the safety of construction workers.
