Description

Technical Field

[0001] This utility model belongs to the technical field of marine wall-climbing robots, and in particular relates to a chassis module structure for a lightweight marine wall-climbing robot. Background Technology

[0002] Marine wall-climbing robots operating on ship surfaces need to balance lightweight design with adaptability to complex working conditions. Traditional steel chassis suffer from excessive weight and weak obstacle-crossing ability. Existing technologies achieve weight reduction through aluminum alloy profiles, composite materials, and modular design, but significant drawbacks remain: magnetic adsorption systems rely on specific array structures to enhance adsorption force, but are significantly affected by the spacing between working surfaces; modular disassembly improves versatility, but insufficient connection strength between modules leads to a decrease in overall rigidity; obstacle-crossing components often use electric push rods to drive magnetic chucks, which increases energy consumption and structural complexity while improving mobility.

[0003] In addition, while fastener-free connection technology reduces weight, it is difficult to guarantee the sealing and shock resistance of the control device. In order to address the above problems, this invention proposes a lightweight chassis module structure for a marine wall-climbing robot. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight chassis module structure for a marine wall-climbing robot to solve the technical problems mentioned in the background art.

The front-end expansion module includes expansion holes and a front-end reinforcing beam disposed on the crossbeam of the front-end expansion module. The middle module includes a main frame, an intelligent control module disposed on the main frame, and a drive wheel disposed at the bottom of the main frame. Traction hooks are fixed on both the left and right sides of the middle module. A permanent magnet adsorption device is fixed at the bottom of the middle module. The tail safety module includes a tail reinforcing beam and a safety fixing hook disposed on the tail reinforcing beam. The front end of the main frame is connected to the front reinforcing beam of the front-end expansion module, and the rear end of the main frame is connected to the tail reinforcing beam of the tail safety module.

[0006] Preferably, a motor connected to the drive wheel is installed at the bottom of the main frame of the middle module. The motor controls the rotation of different wheels to achieve overall steering. At the same time, a power failure brake is integrated at the end of the motor shaft. Under normal power-on state, the brake pads are separated to allow free rotation. After power failure, the spring is compressed to achieve instantaneous locking.

[0007] Preferably, permanent magnet adsorption devices are installed at the bottom front and rear ends of the main frame, and are assembled in parallel and at equal intervals.

[0008] Preferably, the bottom of the permanent magnet adsorption device has an arc-shaped structure. The permanent magnet is made of neodymium iron boron material and uses a Helbeck array magnet structure.
