Description

Technical Field

[0001] This utility model relates to the field of water engineering machinery, and in particular to an adaptive floating platform for a water excavator. Background Technology

[0002] Floating excavators are engineering machines specifically designed for operation in water or wetland environments. The pontoon is the fundamental structure that enables the floating and operation of the excavator, directly determining its stability, buoyancy capacity, and operational safety. Therefore, as a core component of floating excavators, traditional pontoons primarily provide buoyancy and support for the excavator, offering a single function with the following limitations: 1. Inconvenient access: Traditional pontoons lack dedicated boarding structures, requiring the construction of temporary ramps, posing safety hazards; 2. Limited buoyancy adjustment: Fixed pontoons cannot adapt to different operating loads, leading to excessive platform draft; 3. Delayed directional control: Often used solely for buoyancy, they are significantly affected by external waves in complex, undulating waters, resulting in inconvenient pontoon direction control and poor overall stability.

[0003] This utility model solves the three major industry pain points of "difficulty in getting on and off, slow movement, and poor adaptability" that have long existed in waterborne operation platforms by improving the structure and functional modules of the pontoon, and provides a new generation of solutions for waterborne engineering machinery. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adaptive floating platform for amphibious excavators, which can autonomously adjust the attitude of the load-bearing platform and flexibly adjust the direction of travel of the load-bearing platform, thereby improving the stability and operability of the platform. Furthermore, by setting up hydraulic folding plates, it is convenient for excavators to drive into and out of the platform without the need for external equipment, thus improving construction efficiency and overcoming the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides an adaptive floating platform for amphibious excavators, including a load-bearing platform, modular floating boxes, and independent floating boxes;

[0006] The load-bearing platform is rectangular, with four independent pontoons installed at the four corners of the platform and several modular pontoons installed at the bottom of the platform.

[0007] Both the independent pontoons and the modular pontoons are sealed enclosures.

[0008] The independent floating box is equipped with a first water pump, a first water injection valve, a first high-pressure nozzle, and a second high-pressure nozzle. The first water pump and the first water injection valve are used for draining and filling the independent floating box, the first high-pressure nozzle is used to control the rotation of the load-bearing platform in place, and the second high-pressure nozzle is used to provide propulsion.

[0009] The modular pontoon is equipped with a second water pump and a second water injection valve for draining and filling water into the modular pontoon, which provides buoyancy for the load-bearing platform.

[0010] As an improvement of this utility model, the modular pontoon is connected to the bottom of the load-bearing platform via a connecting base. The connecting base includes a hydraulic locking pin and a pin hole. The hydraulic locking pin is located at the bottom of the load-bearing platform, and the pin hole is located on the connecting plate at the top of the modular pontoon. The hydraulic locking pin is inserted into the pin hole by hydraulic control, thereby realizing a detachable connection between the modular pontoon and the load-bearing platform.

[0011] Furthermore, the load-bearing platform has a double-layer steel plate structure, with the upper layer being an anti-slip textured steel plate and the lower layer being a honeycomb-shaped reinforcing rib plate.

[0012] Furthermore, the top of the load-bearing platform is provided with track positioning grooves to prevent the excavator from slipping.

[0013] Furthermore, hydraulic folding plates are installed on both sides of the top of the load-bearing platform, which can be unfolded or retracted by hydraulic control to form a ramp, making it easier for excavators to drive into and out of the load-bearing platform.

[0014] Furthermore, the independent floating box is equipped with a level sensor to monitor the attitude of the load-bearing platform. The level sensor is controlled in conjunction with the first water pump and the first water injection valve through the control system to adjust the attitude of the load-bearing platform.

[0015] With this design, the present invention has at least the following advantages.

[0016] 1. Both independent pontoons and modular pontoons can change the ballast water volume by filling or draining water, adjusting buoyancy according to the current operating environment of the water area, thereby improving the platform's stability and resistance to wind and waves.

[0017] 2. The independent floating boxes located at the four corners are equipped with level sensors to monitor the tilt of the platform in real time. When the tilt angle is greater than 2°, water is automatically injected into the designated independent floating box until the platform's attitude is restored to level.

[0018] 3. Each independent floating box is equipped with a first high-pressure nozzle and a second high-pressure nozzle, which are used for steering and propulsion respectively, making it easier to adjust the platform's direction of travel and improving operability.

[0019] 4. Hydraulic folding plates are installed at the edges of both sides of the load-bearing platform. When unfolded, they form a ramp, which facilitates the entry and exit of excavators without the need for external equipment or manual assistance, thus improving the overall construction efficiency.

[0020] 5. The modular pontoons are installed at the bottom of the load-bearing platform via connecting bases. The number of modular pontoons can be selected according to the working conditions. Damage to a single modular pontoon is easy to replace and repair. When not in use, all modular pontoons can be disassembled for storage. Attached Figure Description

[0028] Please see Figures 1 to 5 This utility model provides an adaptive floating platform for a naval excavator, including a load-bearing platform 1, a modular floating box 7, and an independent floating box 4.

[0029] The load-bearing platform 1 is a rectangular double-layer steel plate structure. The upper layer is a non-slip textured steel plate, and the lower layer is a honeycomb reinforcing rib plate. The load-bearing platform 1 is the main supporting component in this utility model and is used to form a rigid plane for the excavator to park.

[0030] Hydraulic folding plates 5 are installed on both sides of the top of the load-bearing platform 1. They are hydraulically controlled to unfold or retract. When approaching the shore, the hydraulic folding plates 5 automatically unfold according to the current water level, forming a slope and ensuring that the slope is ≤15° to facilitate the entry and exit of excavators. When leaving the shore, the hydraulic folding plates automatically retract, and after retraction, they are flush with the top surface of the load-bearing platform 1.

[0031] The top of the load-bearing platform 1 is provided with track positioning grooves 2. The width and spacing of the track positioning grooves 2 are matched with the excavator tracks, which can prevent slippage after the excavator drives into them.

[0032] There are four independent floating boxes 4, which are installed at the four corners of the load-bearing platform 1. Each independent floating box 4 is a sealed box, and a first water pump 403 and a first water injection valve 402 are installed inside to realize water injection or drainage of each independent floating box 4.

[0033] The independent floating box 4 is equipped with a level sensor 401 for real-time monitoring of the attitude of the load-bearing platform 1. The level sensor 401 is controlled in conjunction with the first water pump 403 and the first water injection valve 402 through the control system. When the level sensor 401 detects that the overall attitude of the load-bearing platform 1 is tilted and the tilt angle is greater than 2°, the control system will send an opening command to the first water pump 403 or the first water injection valve 402 of the designated independent floating box 4 until the load-bearing platform 1 returns to a horizontal attitude.

[0034] The independent pontoon 4 is also equipped with a first high-pressure nozzle 3 and a second high-pressure nozzle 6. The first high-pressure nozzle 3 uses the reaction force of the water jet to make the load-bearing platform 1 rotate in place, thereby adjusting its direction of travel. The second high-pressure nozzle 6 uses the reaction force of the water jet to provide propulsion.

[0035] The modular pontoons 7 are installed at the bottom of the load-bearing platform 1 via connecting bases 8. Each modular pontoon 7 is a cubic sealed cavity. Several modular pontoons 7 are arranged in a rectangular array at equal intervals. Before use, the number of modular pontoons 7 can be selected as needed to provide buoyancy within a specified range.

[0036] The connecting base 8 includes a hydraulic locking pin and a pin control. The hydraulic locking pin is located at the bottom of the load-bearing platform 1, and the pin hole is located on the connecting plate at the top of the module float 7. The hydraulic locking pin is inserted into the pin hole by hydraulic control, which can realize the connection and installation of the module float 7 and the load-bearing platform 1. The operation is convenient and quick.

[0037] The module float 7 is equipped with a second water pump 701 and a second water injection valve 702, which can adjust the ballast water volume by draining or injecting water, thereby adjusting its buoyancy.

[0038] It should be noted that the connecting base 8 can also be used to connect the independent pontoon 4 and the load-bearing platform 1, simply by placing it on the side of the load-bearing platform 1 and the independent pontoon 4. This arrangement further improves the overall convenience of the platform, allowing for the classified transportation and storage of various components while reducing the space occupied.

[0039] In use, this invention first hoists the load-bearing platform 1 to the work area. Based on the excavator's weight, the required buoyancy is calculated, determining the number of modular pontoons 7 to be installed. The modular pontoons 7 are then installed via the connecting base 8. Next, independent pontoons 4 are installed at the four corners of the load-bearing platform 1, and ballast water is injected to half their capacity to lower the platform's center of gravity. Then, the hydraulic folding plate 5 is deployed, and the excavator drives into the track positioning groove 2 on the load-bearing platform 1. The first high-pressure nozzle 3 and the second high-pressure nozzle 6 are activated to push the load-bearing platform 1 to the designated work area. After leaving the shore, the hydraulic folding plate 5 automatically retracts. During operation, the level sensor 401 monitors the platform's attitude in real time and adjusts the platform's attitude by filling and draining the four independent pontoons 4. After the operation is completed, the platform docks, the excavator drives out, the independent pontoons 4 and modular pontoons 7 are emptied of ballast water, disassembled, and stored separately.

[0040] This utility model has a reasonable structure and is easy to operate. It can effectively improve the stability and operability of the platform, and facilitate the excavator to get on and off the platform. Each component can be disassembled, classified, transported and stored, reducing the space occupied.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
