Description

Technical Field

[0001] This utility model relates to the field of work platform technology, specifically a safe and efficient double-layer work platform for bridge demolition. Background Technology

[0002] After years of operation, the strength, rigidity, and stability of old bridges have declined to varying degrees, necessitating their demolition. However, demolition involves many unpredictable factors, making it a technically challenging task. This is where bridge demolition platforms come in. They provide workers with a stable and safe working space, reducing the risks of working at heights and making demolition operations more convenient and efficient, minimizing wasted time. They are adaptable to various bridge structures and demolition scenarios, while also being environmentally friendly and energy-saving. They play a crucial role in the demolition, reconstruction, or renovation of bridges in cities, highways, railways, and other types of infrastructure.

[0003] In existing technologies, single-layer working platforms are a common choice for bridge demolition. However, this makes it difficult for workers to obtain stable support on the platform surface, and they are prone to swaying or losing balance when standing and operating. This means that during demolition operations, workers not only have to overcome the reaction force from tool operation, but also have to be constantly wary of the risks of instability, resulting in numerous safety hazards. At the same time, single-layer platforms lack spatial layering planning, with demolition components, construction tools, and workers crammed onto the same level. Once objects collide or slip, it will directly lead to falling object accidents, especially in the critical stage of cap beam construction. The falling of large components generated from cap beam demolition not only seriously threatens the safety of personnel below, but may also damage bridge piers and surrounding facilities, increasing construction costs and severely reducing the economic efficiency of the construction. Therefore, we propose a safe and efficient double-layer working platform for bridge demolition. Utility Model Content

[0004] The purpose of this invention is to provide a safe and efficient double-layer bridge demolition platform to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safe and efficient double-layer bridge demolition platform, comprising an operating platform and a load-bearing platform. Two clamps (first type) are installed at the bottom of the operating platform, with connecting blocks (first type) fixedly connected to the outside of the clamps.

Multiple mounting slots are provided on the outside of the connecting blocks (second type). A reinforcing component is fixedly connected to the outside of the clamps (second type). A sliding groove is provided inside the reinforcing component. A top block (first type) is slidably connected inside the sliding groove. A rotating block (first type) is fixedly connected to the outside of the top block (first type). An internally threaded cylinder (first type) is rotatably connected inside the rotating block (first type).

A top block (second type) is fixedly connected to the outside of the rotating block (second type). Multiple hollow blocks are fixedly connected to the bottom of the load-bearing platform.

[0006] The top of the load-bearing platform is fixedly connected to two mounting blocks. Both the protective components and the mounting blocks have grooves inside. Multiple pulleys are slidably connected inside the grooves. Support rods are fixedly connected to the top of the pulleys. A protective net is fixedly connected to the adjacent side of every two support rods.

Installation personnel install clamp one via a safety passage, set up the I-beam main longitudinal beam and lock it in place, and install guardrails. Then, clamp two is installed to fix the load-bearing platform, and reinforcement components are installed on both sides of clamp two. Rotating the rotating plate drives the bidirectional threaded column, causing the internal threaded cylinder and related components to slide, strengthening the connection between the load-bearing platform and clamp two, providing additional support, and solving the problem of swaying and imbalance during worker operation, ensuring stability and safety. Support rods and protective netting are installed on the top of the load-bearing platform. Through pulleys, chutes, and reinforcement blocks, protective facilities can be easily deployed and installed, improving connectivity, forming a protective barrier to prevent falling objects from heights, avoiding damage to personnel and facilities, and reducing construction risks. This double-layer platform's reasonable layered planning and safety protection reduce safety accidents and related economic losses, avoid increasing construction costs due to accidents, improve construction efficiency and economy, and effectively overcome the shortcomings of existing single-layer platform space planning.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1 to 7This utility model provides a technical solution: a safe and efficient double-layer bridge demolition work platform, including an operating platform 1 and a load-bearing platform 2. Two clamps 101 are installed at the bottom of the operating platform 1, and connecting blocks 102 are fixedly connected to the outside of the clamps 101. Two guardrails 103 are fixedly connected to the top of the operating platform 1. Two protective components 3 are fixedly connected to the top of the load-bearing platform 2. Two clamps 4 are installed at the bottom of the load-bearing platform 2, and multiple connecting blocks 401 are fixedly connected to the outside of the clamps 4. Multiple mounting slots 402 are opened on the outside of the connecting blocks 401. A reinforcement component 5 is fixedly connected to the outside of the clamps 4. The reinforcement component 5 contains... A sliding groove 501 is provided, and a top block 502 is slidably connected inside the sliding groove 501. The top block 502 is slidably connected to the inside of the reinforcing component 5. A rotating block 503 is slidably connected to the inside of the reinforcing component 5. A rotating block 503 is fixedly connected to the outside of the top block 502. An internally threaded cylinder 504 is rotatably connected inside the rotating block 503. A bidirectional threaded post 505 is threadedly connected inside the internally threaded cylinder 504. A rotating plate 506 is fixedly connected to the outside of the bidirectional threaded post 505. An internally threaded cylinder 507 is threadedly connected to the outside of the bidirectional threaded post 505. A rotating block 508 is rotatably connected to the outside of the internally threaded cylinder 507. Rotating block 2 508 is externally fixedly connected to top block 2 509, and top block 2 509 is externally slidably connected to the inside of hollow block 5010. Rotating block 2 508 is externally slidably connected to the inside of hollow block 5010. Multiple hollow blocks 5010 are fixedly connected to the bottom of the force-bearing platform 2. After the operating platform 1 is installed, clamp 2 4 is installed on its top. Clamp 2 4 is connected and fixed to the external structure through connecting block 2 401 and mounting groove 402. Then, the force-bearing platform 2 is installed on clamp 2 4. To enhance the tightness of the connection between clamp 2 4 and the force-bearing platform 2, reinforcing components 5 are installed on both sides of clamp 2 4, and hollow blocks are installed at the bottom of the force-bearing platform 2. 5010, the operator holds the rotating plate 506 and rotates it. The rotating plate 506 drives the bidirectional threaded column 505 to rotate threadedly in the internal threaded cylinder 1 504 and the internal threaded cylinder 2 507 respectively. Under the drive of the bidirectional threaded column 505, the internal threaded cylinder 1 504 and the internal threaded cylinder 2 507 move in opposite directions. The internal threaded cylinder 1 504 drives the rotating block 1 503 and the top block 1 502 to slide inside the reinforcing component 5. The internal threaded cylinder 2 507 drives the rotating block 2 508 and the top block 2 509 to slide inside the hollow block 5010, thereby enhancing the connection between the force-bearing platform 2 and the clamp 2 4 and providing additional support for the force-bearing platform 2.

[0025] Two mounting blocks 301 are fixedly connected to the top of the load-bearing platform 2. Both the protective component 3 and the mounting blocks 301 have internal grooves 302. Multiple pulleys 303 are slidably connected inside the grooves 302. Support rods 304 are fixedly connected to the top of each pulley 303. A protective net 305 is fixedly connected to the adjacent side of every two support rods 304. Reinforcing blocks 306 are fixedly connected to the four corners of the top of the load-bearing platform 2. Limiting grooves 307 are formed inside the reinforcing blocks 306. The support rods 304 and protective nets 305 are slidably installed on the top of the load-bearing platform 2, in conjunction with the pulleys 303, on the protective component 3 and the mounting blocks 301. Multiple support rods 304 and protective nets 305 are unfolded in the sliding groove 302 of the mounting block 301. The support rods 304 at the other end are slid into the limiting grooves 307 inside the reinforcing block 306 to complete the installation of the protective nets 305. This improves the ease of installation of the protective nets 305. Moreover, by using the reinforcing blocks 306 at the four corners of the top of the load-bearing platform 2, the connection between the horizontal support rods 304 and the protective nets 305 and the vertical support rods 304 and the protective nets 305 is enhanced, improving the stability and safety of the entire protective structure and ensuring the safety of construction personnel working on the double-layer working platform.

[0026] Two connecting blocks 401 are symmetrically distributed outside the clamp 4, and two connecting blocks 102 are symmetrically distributed outside the clamp 101. The installer uses the connecting blocks 102 to install and fix the clamp 101, ensuring that the operating platform 1 is stably installed in the designated position.

[0027] The pulley 303 is externally slidably connected to the inside of the mounting block 301, and the support rod 304 is externally slidably connected to the inside of the mounting block 301. When installing and adjusting the protective net 305, the pulley 303 slides along the slide groove 302, reducing the friction when the support rod 304 slides, making the unfolding and retraction of the protective net 305 easier and more convenient.

[0028] The working principle of this utility model is as follows: When installing the operating platform 1, it is first assembled at the bottom of the old bridge pier. Then, a truck crane is used to move the assembled operating platform 1 to the designed position. The installers use the safety passage between the old and new bridges to install the clamp 101 via the connecting block 102. After the clamp 101 is installed, an I-beam is set on the corbel as the main load-bearing longitudinal beam. The main longitudinal beams are fixed by round steel tie rods and steel pipe supports to ensure that the main crossbeams are vertically stressed. Then, a guardrail 103 is installed on the top of the operating platform 1. After the operating platform 1 is installed, clamp 2 4 is installed on the top of the operating platform 1, so that clamp 2 4 is installed and fixed with connecting block 2 401 and mounting groove 402. Then, the load-bearing platform 2 is installed with clamp 2 4. Then, in order to make the connection between clamp 2 4 and load-bearing platform 2 feel tight, it is only necessary to fix clamp 2 4 at the bottom of the bridge pier. Reinforcing components 5 are installed on both sides. Then, a hollow block 5010 is installed at the bottom of the load-bearing platform 2. The rotating plate 506 is held and rotated, causing the bidirectional threaded column 505 to rotate threadedly inside the inner threaded cylinder 1 504 and the inner threaded cylinder 2 507 respectively. The inner threaded cylinder 1 504 and the inner threaded cylinder 2 507 move in opposite directions. The inner threaded cylinder 1 504 slides inside the reinforcing component 5 in conjunction with the rotating block 1 503 and the top block 1 502. Simultaneously, the inner threaded cylinder 2 507 slides inside the hollow block 5010 in conjunction with the rotating block 2 508 and the top block 2 509. This enhances the connection between the load-bearing platform 2 and the clamp 2 4, providing additional support to the load-bearing platform 2. Then, the support rod 304 and the protective net 305 are installed on the top of the load-bearing platform 2 for protection, thus ensuring the safety of construction personnel.

[0029] Example 2

[0030] Please see Figures 4 to 5 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that when installing the support rod 304 and the protective net 305, it is only necessary to slide the support rod 304 and the protective net 305 in the groove 302 with the pulley 303. This allows multiple support rods 304 and protective nets 305 to be unfolded, and then the support rod 304 at the other end can be slid into the reinforcement block 306 to complete the installation. This improves the convenience of the guardrail. At the same time, the reinforcement blocks 306 at the four corners of the top of the force-bearing platform 2 improve the connection between the horizontal support rods 304 and the protective net 305 and the vertical support rods 304 and the protective net 305.
