Description

A kind of safe and simple cylinder filling frame

Technical field

The utility model is related to a kind of safe and simple cylinder filling frame, category cylinder filling servicing unit field.

Background technology

In gas cylinder (also referred to as " steel cylinder ") gas fill be gas generation enterprise important step, gas cylinder in bulk fills, The mode that many companies all take with lattice in bulk to fill at present, substitutes traditional mode along blast wall single-row arrangement, with Improve efficiency.But it is exactly to fill flexible pipe and the connection of bottle head and asking for separating that lattice in bulk, which fill the very big practical problem of mode one, Topic, if flexible pipe can not be lifted, lattice in bulk enter fill when, flexible pipe can be collided, gas bottle head can be damaged；Filling After end, lattice in bulk are pulled out when filling, and flexible pipe can be collided again；Therefore, fill flexible pipe to be required to easily lift, It can guarantee that efficiency.

At present, in the market has had the design of pneumatic hydraulic lifting frame, but is all a total air induction hose lifting, then from The mode of point 16 flexible pipes on collecting pipe, but all not accounting for solution has the safety for closing the leakage pipeline when filling leakage to ask Topic；And apparatus cost is high, maintenance cost is also high.The design of some fueling stations of East China, is to use the mode for filling hose locker will Flexible pipe is scaled in casing, and pull out flexible pipe from chest by root during connection gas cylinder is connected with gas cylinder, fills after end, that pulls down fills Dress head can be withdrawn into casing by the gravity of flexible pipe.But also each pipeline that fills is set up individually not on master control panel Valve.

Studied before the applicant filling frame, and in the U of Authorization Notice No. CN 204345258, it is entitled " a kind of Filling head can cylinder filling frame of the automatic lifting with device for monitoring temperature " Chinese utility model patent in, describe one kind and fill Fill head can cylinder filling frame of the automatic lifting with device for monitoring temperature, including carried for the inflation platform and Duo Gen for placing gas cylinder The gas tube of joint is filled soon, joint is filled soon gas tube is communicated to by connecting tube, gas tube is arranged on the top of inflation platform simultaneously Connected with high-pressure air source, in addition to the support being arranged on inflation platform, support is provided with guide rail, and guide rail is provided with can be along guide rail Lead-frame is fixedly connected with the guide block of up and down motion, guide block, lead-frame is located at the top of gas cylinder, and the gas tube correspondence is fixed In lead-frame, the top of lead-frame is provided with pulley, in addition to around the conductor rope being located on pulley, one end and the lead-frame of conductor rope are consolidated Fixed connection, the other end of conductor rope is connected with counterweight, and the weight of counterweight is more than the weight of lead-frame.

A total air induction hose is with the lifting of crane one in the patent, then picks out from the collecting pipe on crane 16 Flexible pipe is filled, fill flexible pipe by 16 picks out to gas cylinder head from the valve on collecting pipe, lifts frame lift band together with collecting pipe Dynamic total air induction hose lifting；But actually these valves be in filling process can not go close (especially pressure is more than 100 Kilogram when), even if fill initial stage find have leakage, it is also unsafe to go to close corresponding valve, is detected in filling process It during leakage, will be unable to individually close the gas cylinder, the valve that can only be closed on total valve or collecting pipe, will own in the lattice in bulk After gas cylinder release, then the gas cylinder of leakage is picked out, this will cause very big waste, and reduction fills efficiency.

In consideration of it, the present inventor carries out in-depth study to above mentioned problem, there is this case generation then.
