The invention provides a bionic self-adaptive anti-subsidence walking wheel and a control method thereof. The bionic self-adaptive anti-subsidence walking wheel comprises a walking wheel flange plate, walking wheel leg and foot single bodies, a pose sensing system and a controller. A plurality of walking wheel leg and foot single bodies are arranged on the walking wheel flange plate in the circumferential direction; each walking wheel leg and foot single body comprises a bionic tendon-bone cooperation mechanism and a bionic tendon driving mechanism; the bionic tendon driving mechanism can open and close the bionic tendon-bone cooperation mechanism; the pose sensing system is used for detecting a height signal from a walking wheel flange plate to the ground and transmitting the height signal to the controller; and the controller compares the height signal with a preset value and controls the bionic tendon driving mechanism to open and close the bionic tendon-bone cooperation mechanism according to a comparison result. Self-adaptive opening and closing of the toe web of the bionic walking wheel are achieved, the walking wheel leg and foot single body is simple in overall structure, the adaptability and application universality of the walking wheel are improved, and the walking wheel can be applied to a robot to improve the trafficability of the robot on the soft ground.

The invention relates to the technical field of mine car cab structures, in particular to a mine car cab high-safety anti-torsion structure which comprises a mine car body, a cab base is fixedly mounted on the mine car body, a plurality of reinforcing columns are fixedly connected to the cab base, and a cab footstock is fixedly connected to the reinforcing columns. Wherein a retracting and releasing mechanism is rotatably connected in the two reinforcing columns, a moving frame is rotatably connected to the retracting and releasing mechanism, an anti-toppling mechanism is arranged in the moving frame in a sliding fit mode, and a transmission mechanism is rotatably connected in the moving frame. The mine car is supported, the danger that the mine car turns on one side or inclines too much can be effectively avoided, the life safety and operation safety of miners are guaranteed, the stability of the mine car in a complex operation environment is effectively improved, the risk of accidents is reduced, and safety and high efficiency of mine operation are guaranteed.

The utility model discloses a bridge and culvert height-limiting protective frame structure suitable for earth roads and sandstone roads, which relates to the technical field of bridge and culvert height-limiting protective frames and comprises a pair of seamless steel tube stand columns and a height-limiting cross beam positioned at the upper ends of the seamless steel tube stand columns. The upper ends of the seamless steel pipe stand columns are connected with the height limiting cross beam through flanges, the lower ends of the seamless steel pipe stand columns are connected with foundations through flanges, and a ground beam is arranged between the foundations. In work points such as a soil road and a sand stone road, the ground beam can enlarge the foundation bottom area, reduce the foundation pressure of unit area and prevent overlarge local settlement, the ground beam is of a reinforced concrete structure, the clear height from the height limiting cross beam to the road surface can be effectively controlled, the risk that bridges and culverts are collided by vehicles is avoided, and safety is improved.

This invention relates to a range-extended, all-electric, lightweight lotus root harvesting equipment. The technical solution is as follows: a buoyancy lifting chassis is composed of an electric drive walking module, a frame assembly, a buoyancy box, and a four-point linkage lifting mechanism; a low-pressure, high-flow-rate oscillating jet module, consisting of a jet module and a submersible pump suction module, is mounted on the buoyancy box to provide jet power for the entire machine; the diesel engine of the power generation module drives a generator to output three-phase AC power, which is then converted into DC power by a rectifier to charge the battery module; the battery module's power is converted by an inverter to power multiple submersible pumps, an underwater motor, a lifting platform, and a through-type stepper motor. The beneficial effects are: firstly, the oscillating floating jet mechanism improves harvesting efficiency; secondly, the diesel engine generates electricity to achieve energy storage and range extension, while the underwater motor's high-proportion reducer drives the rubber tracks; simultaneously, the electric drive enables multiple submersible pumps to work together, leveraging their high efficiency and head.
