Mechanical arm for hydrogen filling of hydrogen energy automobile

Abstract

The invention discloses a mechanical arm for hydrogen filling of a hydrogen energy automobile, and relates to the field of mechanical clamping, the mechanical arm comprises a rack and a baffle, a primary air cylinder is horizontally arranged on the rack, a secondary air cylinder is arranged at the output end of the primary air cylinder, and the output end of the secondary air cylinder movably penetrates through the middle of the end face of a follow-up rod and then extends into a cavity; a clamping ring is arranged on the outer wall of the extension section of the output end of the primary air cylinder, a plurality of L-shaped connecting rods are arranged on the outer wall of the end, back to the clamping ring, of the ejector rod, the hydrogenation pipe is communicated with the gas filling cavity, and the ejector rod, the spring and the through holes are located on the same side of the partition plate. A fastening assembly used for clamping a connector of the air inlet pipe is arranged on the horizontal section of the connecting rod. The hydrogenation pipe of the hydrogen energy traffic equipment is positioned and clamped through the fastening head, manual work is replaced for automatic butt joint, detection and hydrogenation procedures, and then the workload of front-end workers is reduced.

Description

technical field [0001] The invention relates to the technical field of hydrogenation, in particular to a mechanical arm for hydrogenation charging of hydrogen vehicles. Background technique [0002] Hydrogen fuel cell vehicles have the advantages of good environmental performance, high conversion efficiency, fast refueling speed, and long cruising range. They are a new direction for future automobile development, and hydrogen refueling stations are gas stations that provide hydrogen for fuel cell vehicles. The most common form of hydrogen refueling station is ground-fixed hydrogen production and refueling station. The hydrogen source of such a hydrogen refueling station usually relies on electrolyzed water or natural gas reforming to make hydrogen and then purifies it, then transports it to the hydrogen refueling station or directly stores it. It is stored in the device of the hydrogen refueling station. When it is necessary to inject hydrogen into the car, the hydrogen is e...

Problems solved by technology

[0003] The existing technology has the following disadvantages: when the existing hydrogen refueling station is performing hydrogen refueling, the front-end staff first needs to detect the intake pipe of the hydrogen energy vehicle to determine whether there is any leakage at the nozzle of the intake pipe; and then transmit the detection results To the background terminal, after being authorized, the front-end staff manually transfer the hydrogenation pipe to the intake pipe, after manual docking and fastening, the station terminal starts the switch valve, and the hydrogenation process begins; this type of operation not only increases labor costs and labor intensity, The front-end staff are always in the hydrogenation environment to maintain real-time monitoring, and the degree of automation is low, which increases the difficulty of operation and reduces the safety and reliability of the hydrogenation process
