Description

Technical Field

[0001] This utility model relates to the field of engineering machinery, specifically an adaptive chassis for environmentally friendly underground construction operations. Background Technology

[0002] In underground construction operations, such as mining, tunnel construction, and underground engineering, the chassis, as a key component of construction equipment, bears the responsibility for the stable operation and efficient functioning of the equipment. However, traditional chassis designs have many shortcomings when dealing with complex and ever-changing underground working conditions.

[0003] Traditional chassis mostly use fixed track structures, which cannot adaptively adjust to ground conditions. When the ground is uneven or obstacles are encountered, fixed tracks can easily cause the chassis to become unbalanced, even leading to equipment failure, seriously affecting the stability and safety of operations. In addition, the power systems of traditional chassis are often single, unable to simultaneously meet the needs of hydraulic and pneumatic power output, limiting the versatility and flexibility of the equipment in underground construction operations.

[0004] In terms of power mode, traditional chassis typically only offer one of either diesel or electric power, lacking adaptability to different working conditions. When frequent changes in work locations or different operational needs are required, the power system of traditional chassis often fails to meet the requirements of efficient and environmentally friendly operation.

[0005] Meanwhile, traditional chassis also present many inconveniences in terms of maintenance and upkeep. Due to the compact and complex layout of components, daily maintenance and repair are more difficult, increasing equipment maintenance costs and downtime.

[0006] In summary, traditional chassis suffer from insufficient adaptability, a single power system, and inconvenient maintenance when dealing with complex and ever-changing underground working conditions, failing to meet the demands of modern underground construction operations for high efficiency, stability, multi-functionality, and environmental friendliness. Therefore, there is an urgent need for a new type of chassis capable of adapting to complex working conditions, possessing dual power modes, and facilitating maintenance, in order to improve the efficiency and quality of underground construction operations. Utility Model Content

The connecting shaft component includes a rotating shaft and axle seat structure that allows the tracks to rotate forward and backward relative to the chassis body. Through the coordinated action of these two components, the left and right tracks can flexibly swing up and down and tilt, thereby ensuring that the chassis can maintain a stable walking and working state in various complex terrains and achieve a height-adaptive function.

[0010] The adaptive chassis for environmentally friendly underground construction operations further includes a swing beam and a swing seat. One end of the swing beam is fixedly connected to the chassis body, and the other end is connected to the track through the swing seat. The swing seat is designed with a bearing or hinge structure that allows the swing beam to swing left and right inside it, so as to realize the adaptive left and right swing of the track.

When the outrigger extends to a certain position, the chassis's walking function is locked. The chassis can only resume walking when the outrigger is raised to a certain height, thereby achieving interlocking protection between the outrigger and the walking function.

[0016] The aforementioned adaptive chassis for environmentally friendly underground construction operations also includes an intelligent cab, which is equipped with a display screen and control system to display engine operating data, overall machine working status, pile driver navigation information, and camera monitoring images in real time. It is also equipped with an inverter to provide 220V AC power to construction personnel.
