2results about How to "Reduce load weight" patented technology

The invention relates to a bag holder, in particular to a four-connecting-rod tilt cylinder bag opening type bag holder. A first lifting assembly and a second lifting assembly in the bag clamping device are oppositely arranged on the two sides of a main frame, each of the first lifting assembly and the second lifting assembly comprises a first linear driving piece and a four-connecting-rod mechanism, and a tailstock of each first linear driving piece is hinged to the upper end of the main frame through the corresponding four-connecting-rod mechanism; the first bag opening rod and the second bag opening rod are arranged on the two sides of the front protection plate and the rear protection plate and installed at the output ends of the first linear driving pieces in the first lifting assembly and the second lifting assembly correspondingly. The first bag opening assembly and the second bag opening assembly are arranged on the sides, away from each other, of the front protection plate and the rear protection plate correspondingly, and the mounting ends of the first bag opening assembly and the second bag opening assembly are hinged to the front protection plate and the rear protection plate correspondingly. The two output ends of the first bag opening assembly and the two output ends of the second bag opening assembly are hinged to first linear driving piece front bases in the first lifting assembly and the second lifting assembly respectively. The load weight of the output end of the first linear driving part is greatly reduced, and the structure is greatly simplified.

The utility model relates to the field of inspection robot power supply, concretely relates to a kind of intrinsic safety type inspection robot lithium battery multipath parallel driving walking structure, including four brushless motors connected with four wheels respectively, the brushless motor all adopt intrinsic safety type, battery pack for its separate power supply is equipped on each brushless motor, the intrinsic safety type inspection robot lithium battery multipath parallel driving walking structure, by the parallel power supply mode of intrinsic safety type lithium battery, 4 intrinsic safety type brushless motor driving of intrinsic safety type inspection robot is driven, realize the intrinsic safety driving design of inspection robot, lighten the robot load weight, improve the cruising ability. Parallel driving walking control structure is powered by 5-way intrinsic safety lithium battery, lithium battery is designed as Ex ib I Mb explosion-proof grade, wherein 4-way is respectively powered to four driving wheels, 1-way is powered to control host computer. After parallel connection of each lithium battery, double overcurrent overvoltage charge-discharge protection of ib grade is realized after battery protection circuit.
