Description

Technical Field

[0001] This utility model relates to the technical field of construction operation platforms, specifically a mobile construction operation platform for the outer side of a crash barrier. Background Technology

[0002] Crash barriers are an important part of bridge deck systems and highway pavements. They can be seen in the middle and along the sides of highways, subways, and roads. Their function is to prevent vehicles from veering off course and causing traffic accidents, thus saving lives. The quality of the crash barriers directly affects personal and property safety in the event of an accident, and their appearance directly impacts the aesthetics of the entire bridge or road. Therefore, crash barrier repair is a crucial aspect of road and bridge construction.

[0003] After the crash barrier is poured and solidified, it still requires finishing work such as roughening. However, the outer side of the crash barrier, i.e., the side facing away from the bridge deck, requires work at height. Traditionally, the finishing of the outer side of the crash barrier uses a fixed suspended platform as a work platform for workers. This is cumbersome and requires a truck crane, which cannot meet the requirements of on-site construction. Furthermore, it results in a low safety factor for workers and excessive equipment and labor costs. Therefore, some construction companies have created simple construction platforms that can be installed on the side of the crash barrier, allowing workers to work from within these platforms. Public literature also reports on some such construction platforms, for example:

Chinese Patent: A Crash Barrier Repair Trolley, Application No.: 201620417697.7, Application Date: 2016.05.10, Abstract: A crash barrier repair trolley includes a set of parallel top beams (1), suspension beams (2) located at one or both ends of each top beam, drive wheels (3) installed on the bottom surface of each top beam, a traveling motor (4) installed on at least one top beam, driven wheels (5) installed on the inner side of the lower part of each suspension beam, and a drive wheel installed on a top beam without a suspension beam. A suspended operating platform (6) is installed at the end or middle of the top beam; adjacent top beams are connected by longitudinal beams (8); when the suspended operating platform is installed at the middle of the top beam, there are cantilever beams at both ends of the top beam, two drive wheels (3) are installed on the bottom surface of the top beam, and driven wheels (5) are symmetrically installed on the inner side of the two cantilever beams; when the suspended operating platform is installed at the end of the top beam without a cantilever beam, driven wheels are installed on the lower inner side of the suspended operating platform; the drive wheels and driven wheels travel against the top and side surfaces of the crash barrier, respectively. This utility model has a stable and reliable structure, which can ensure the safety of construction personnel, good construction quality, and high construction efficiency.

Chinese Patent: A Movable Working Platform for the Outer Span of a Bridge Crash Barrier, Application No.: 202122523776.X, Application Date: 2021.10.20, Abstract: This utility model discloses a movable working platform for the outer span of a bridge crash barrier, comprising a frame installed on the crash barrier and the bridge body. The frame is S-shaped, with a walking platform at the bottom of the frame located inside the crash barrier. Universal wheels capable of moving along the bridge surface are installed between the walking platform and the bridge body. Several universal wheels are installed between the middle of the frame and the crash barrier. A working platform, guardrail, and safety railing are provided on the frame located outside the crash barrier. This movable working platform for the outer span of the utility model can be adjusted according to different concrete crash barrier forms, allowing for flexible, fast, and efficient implementation. It features a novel structure, is easy to use, and effectively ensures the smooth implementation of the bridge concrete crash barrier and personal safety.

[0006] 3. Chinese Patent: A Movable Anti-collision Wall Decoration Platform, Application No.: 201921255008.7, Application Date: 2019.08.05, Abstract: This utility model relates to the field of bridge construction technology, specifically a movable anti-collision wall decoration platform, including a support frame and a basket. The support frame is horizontally arranged with one end bent vertically downwards, and the other end is hinged to the basket. The bottom axle of the horizontal section of the support frame is connected to a top roller for pressing against the top surface of the anti-collision wall. The upper axle of the bent section of the support frame is connected to an inner roller for abutting against the inner side of the anti-collision wall. The upper axle of the basket is connected to an outer roller for pressing against the outer side of the anti-collision wall. The axes of the top rollers are perpendicular to the extension direction of the anti-collision wall and the axis of the inner rollers, respectively. This utility model has a simple structure, requires no lifting equipment for support, and relies solely on the anti-collision wall itself for support. Simultaneously, the rollers contact the anti-collision wall, making it not only easy to move but also preventing its own weight from scratching or damaging the anti-collision wall itself.

[0007] 4. Chinese Patent: Mobile Platform for Highway Bridge Crash Barriers, Application No.: 201320142917.6, Application Date: March 26, 2013, Abstract: This utility model discloses a mobile platform for highway bridge crash barriers, including a balancing frame installed inside the highway bridge crash barrier, an operating platform installed outside the highway bridge crash barrier for carrying construction personnel, and a connecting frame for connecting the balancing frame and the operating platform. One end of the connecting frame is connected to the operating platform, and the other end of the connecting frame crosses the highway bridge crash barrier and connects to the balancing frame. The balancing frame is equipped with at least two rollers (first type) that can move along the inner side of the highway bridge crash barrier, and the connecting frame is equipped with at least two rollers (second type) that can move along the top surface of the highway bridge crash barrier and at least two rollers (third type) that can move along the outer side of the highway bridge crash barrier. This mobile platform for highway bridge crash barriers has a simple structure, is easy to use, improves work efficiency, has low production costs, and is easy to promote and use.

[0008] Applied research revealed that the aforementioned publicly available work platform lacks handrails when workers climb in, causing significant fear and impacting construction efficiency. Furthermore, if designed for a large space, manual installation is difficult; if designed as a lightweight model, the operating space is limited, making it inconvenient to access tools and materials. Therefore, developing a mobile platform that facilitates installation and allows easy access to tools and materials outside the crash barrier is a pressing technical problem for those in the relevant field.
