Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, specifically to an anti-lifting support platform for the repair of high-pile wharves. Background Technology

[0002] High-pile wharves are a major type of wharf built on soft soil foundations. They are widely used on soft soil foundations along the coast and rivers and play an important role in marine port engineering. However, their maintenance and repair work often presents many challenges due to their proximity to water. At present, research on the design and construction technology of construction platforms for the repair of high-pile wharves at home and abroad is still in the exploratory stage, lacking systematic and standardized mature processes.

[0003] The existing high-pile wharves mostly use floating platforms for repair. However, in actual use, floating platforms are prone to tilting or instability when affected by tides, currents and severe weather (such as strong winds and heavy rain), posing a significant safety hazard. At the same time, their design and structural bearing capacity are limited, making it impossible to meet the conditions for multiple personnel to work. They also require dedicated access channels, and the platform must be moved to the disembarkation point before reaching the work platform. This exposes a series of shortcomings such as poor adaptability, weak stability, and insufficient bearing capacity.

[0004] To overcome these problems, a design and construction technology for a high-pile wharf repair platform is proposed. This technology can not only effectively solve the shortcomings of floating platforms, but also provide flexible and efficient support for bridge repair or other water repair work, thus having high engineering application value. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-lifting support platform for the repair of high-pile wharves, which solves the problems mentioned in the background.

[0006] This utility model provides the following technical solution: a reverse-hanging support platform for high-pile wharf repair, comprising: an I-beam, the I-beam being fixed on a wharf platform made of cast concrete, a ladder being provided at the end of the I-beam suspended outside the wharf platform, and an assembly module being connected to the side of the ladder, the assembly module being located below the wharf platform;

[0007] The ladder includes four vertical poles, with multiple sets of handrails spaced apart on adjacent poles, and inclined braces between adjacent poles. The top of the poles is mounted on an I-beam via fasteners. A first step is provided on the handrail, and a ladder frame is suspended from the handrail.

[0008] The bottom of the dock platform is equipped with a cantilever frame, and the assembly module is suspended below the cantilever frame.

[0009] Preferably, the side of the ladder is fixed to the dock platform by two wall tie members, and one wall tie member located at the bottom of the dock platform is connected to both the ladder and the assembly module.

[0010] Preferably, the assembly module includes multiple sets of horizontal bars extending parallel from the ladder, and multiple sets of column rods are vertically arranged on the horizontal bars. The horizontal bars located below the cantilever frame are suspended by the column rods.

[0011] Preferably, multiple sets of inclined bracing bars are provided on the bottom crossbar, and the tops of the multiple sets of inclined bracing bars are respectively installed on the ladder and the cantilever frame.

[0012] Preferably, a second step is provided on the bottom crossbar, parallel to the bottom of the dock platform, and the second step is integrated with the first step located at the bottom of the ladder.

[0013] Preferably, the cantilever frame is a right-angled triangular welded support, and the cantilever frame is installed on the dock platform using expansion bolts.

[0014] Preferably, a lifting buckle is welded onto the I-beam, a lifting rope is provided on the lifting buckle, the end of the lifting rope away from the lifting buckle is tied to the ladder, and a hook is provided in the middle of the lifting rope.

[0015] Preferably, the I-beam is provided with multiple sets of U-shaped frames, and the U-shaped frames are installed on the wharf platform using rebar anchoring technology.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The inverted support platform for the repair of the high-pile wharf uses an I-beam as the core support component on the wharf platform. By distributing the weight of the inverted support platform through the part in contact with the wharf platform, the overall stability and load-bearing capacity of the platform are improved, as well as the safety of the inverted support platform in harsh environments. Subsequently, the assembled ladder is lowered from the suspended part of the I-beam using lifting equipment, and a temporary assembly module is temporarily assembled under the wharf platform until the workers can directly reach the repair area, thus eliminating the need to use a floating platform. This also solves a series of shortcomings of floating platforms, such as poor adaptability, weak stability, and insufficient load-bearing capacity.

[0018] 2. The inverted support platform for the repair of the high-pile wharf improves the load-bearing capacity of the platform by setting up ladders and assembling modules and using anchoring to connect with the existing concrete structure. This allows the platform to support the entry of some mechanical equipment, tools and construction personnel, meeting the needs of high-intensity tasks. After the inverted support platform is assembled, the ladders can be used to directly access the platform, ensuring that workers can safely and efficiently go up and down the platform.

[0029] 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.

[0030] Please see Figure 1-9 A reverse-hanging support platform for high-pile wharf repair includes: an I-beam 2, which is fixed on a wharf platform 1 made of concrete casting; a ladder 3 is provided at the end of the I-beam 2 that is suspended outside the wharf platform 1; an assembly module 4 is connected to the side of the ladder 3; and the assembly module 4 is located below the wharf platform 1.

[0031] The ladder 3 includes four vertical poles 31, with multiple sets of railings 32 spaced apart on adjacent poles 31, and inclined braces 33 between adjacent poles 31. The top of the poles 31 is mounted on the I-beam 2 via fasteners 34. The railings 32 are equipped with first steps 35, and ladder frames 36 are suspended from the railings 32.

[0032] A cantilever 5 is installed at the bottom of the dock platform 1, and the assembly module 4 is suspended below the cantilever 5.

[0033] The side of the ladder 3 is fixed to the dock platform 1 by two wall tie members 6. One of the wall tie members 6 at the bottom of the dock platform 1 is connected to both the ladder 3 and the assembly module 4. The ladder 3 is fixed to the dock platform 1 by the wall tie member 6, so that it has a stable support, increases the risk resistance, and is not prone to tilting or instability.

[0034] The assembly module 4 includes multiple sets of horizontal bars 41 extending parallel from the ladder 3. Multiple sets of column bars 42 are vertically installed on the horizontal bars 41. The horizontal bars 41 located below the cantilever frame 5 are suspended by the column bars 42. After the ladder 3 is hoisted and installed securely, multiple sets of horizontal bars 41 are directly extended from the ladder 3 and spliced ​​to form the assembly module 4 until the assembly module 4 reaches the repair location.

[0035] Among them, multiple sets of inclined fixing rods 43 are inclinedly arranged on the bottom crossbar 41. The tops of the multiple sets of inclined fixing rods 43 are respectively installed on the ladder 3 and the cantilever frame 5. By setting multiple sets of inclined fixing rods 43, the rods on the assembled module 4 are intersected to form different angles after the module is formed, thereby improving its stability and avoiding deformation.

[0036] Among them, a second step 44 is provided on the bottom crossbar 41, which is parallel to the bottom of the dock platform 1. The second step 44 is integrated with the first step 35 at the bottom of the ladder 3, connecting the second step 44 on the assembly module 4 with the first step 35 at the bottom of the ladder 3. This allows workers to walk directly from the ladder 3 to the assembly module 4, improving the safety of workers when passing through.

[0037] The cantilever 5 is a right-angled triangular welded support, and the cantilever 5 is installed on the dock platform 1 with expansion bolts. The cantilever 5 provides a support for the subsequent longer assembly module 4, so that the assembly module 4 can extend to the bottom of the dock platform 1 for repair.

[0038] The I-beam 2 is welded with a lifting buckle 8, and a lifting rope 9 is installed on the lifting buckle 8. The end of the lifting rope 9 away from the lifting buckle 8 is tied to the ladder 3, and a hook is installed in the middle of the lifting rope 9. One end of the lifting rope 9 is placed on the I-beam 2. When the ladder 3 is suspended in the air, the outside of the ladder 3 is connected to the lifting buckle 8 using the lifting rope 9. Then, the hook of the lifting rope 9 is pulled by the lifting equipment, so that the ladder 3 is subjected to force on one side, reducing the lateral tension on the bottom of the ladder 3 after the assembly module 4 is installed, thereby avoiding the assembly module 4 from tilting due to gravity.

[0039] Among them, multiple sets of U-shaped frames 7 are installed on the I-beam 2. The U-shaped frames 7 are installed on the wharf platform 1 using rebar anchoring technology. By installing the U-shaped frames 7 on the wharf platform 1, the I-beam 2 is fixed using the U-shaped frames 7, so that the part of the I-beam 2 in contact with the wharf platform 1 distributes the weight of the anti-hanging support platform, thereby improving the overall stability and load-bearing capacity of the platform.

[0040] The working principle is as follows: When using the reverse-lifting support platform to repair the bottom of the high-pile wharf, firstly, two sets of parallel I-beams 2 are fixed on the wharf platform 1 using U-shaped frames 7. Then, the ladder 3 is assembled as a whole on the ground. Then, the lifting equipment is used to lift it down from the suspended end of the I-beam 2. Finally, the ladder 3 is fixed to the I-beam 2 and the wharf platform 1. Then, the lifting rope 9 is used to connect the outward side of the ladder 3 to the I-beam 2. The lifting equipment provides a lateral pulling force to the ladder 3. Then, the workers reach the bottom of the ladder 3 and build the assembly module 4. The assembly module 4 is fixed by the cantilever frame 5 during the construction process until the assembly module 4 reaches the repair part at the bottom of the wharf platform 1.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
