Detailed description of the invention
By reference to the accompanying drawings, present pre-ferred embodiments is described in further details.
A kind of pneumatic cylinder valve charging crane, mainly comprises a few great institutions, conveying frame 1, gas cylinder clamping device 2, cylinder valve handler 3, clamp positioning device 4 and air-channel system 5.Gas cylinder is carried through conveying frame 1, and clamped by the gas cylinder clamping device 2 above conveying frame 1, after clamping, cylinder valve handler 3 pairs of gas cylinder valves carry out tripping action.Wherein cylinder valve handler 3 can carry out longitudinal adjustment by clamp positioning device 4, and gas cylinder clamping device 2, cylinder valve handler 3 are subject to air-channel system 5 and carry out pneumatic control.
Conveying frame 1 adopts horizontal operation, is provided with roller 11 in bottom, and roller 11 rotates and carries out gas cylinder conveying, and when conveying puts handling in place, gas cylinder is laterally settled, and cylinder valve aims at cylinder valve handler 3.
Gas cylinder clamping device 2 comprises compression cylinder 21 and pressure head 22, cylinder piston in compression cylinder 21 is furnished with guide post 59, and for preventing piston from rotating, it is connected with pressure head 22 by screw thread, the lower surface of pressure head 22 becomes downward " V " type groove, for being fixed gas cylinder.
Cylinder valve handler 3 comprises fixture 31, shaft coupling 32 and air motor 33, and air motor 33 is subject to loading and unloading the control of control valve 54, can bidirectional rotation, and a direction is dress valve, and another direction is for unloading valve.
Clamp positioning device 4 comprises worm-and-wheel gear 41, dovetail type chute 42 and motor bracket 43.Motor bracket 43 adopts with the worm gear 411 lower end screw rod in worm-and-wheel gear 41 and is threaded.Motor bracket 43 is provided with dovetail type chute 42, is connected with dovetail type chute 42 bottom air motor 33, air motor 33 can be moved on dovetail type chute 42.Worm gear 411 in worm-and-wheel gear 41 and worm screw 412 are the work of cooperatively interacting, and worm screw 412 drives worm gear 411 to rotate, and worm gear 412 lower end screw rod rotates, and the longitudinal direction realizing air motor 33 regulates.The handwheel 6 that in the present embodiment, worm screw 412 by rotary worm 412 connects controls to rotate.
Air-channel system 5 comprises three linked piece 51, pinch control valve 53, handling control valve 54.External air source forms two gas circuits by three linked piece 51 branch, leads up to and loads and unloads control valve 54 connection control air motor 33, control air motor 33 Double-directional rotary.Separately lead up to pinch control valve 53 connection control compression cylinder 21, primary responsibility controls pressure head 22 and compresses gas cylinder.Each gas circuit is provided with pressure regulator valve 55 and Pressure gauge 56.Regulate the power output of pressure regulator valve 55 adjustable pneumatic motor 33 rated output torque and compression cylinder 21, and with pressure pattern display feedback on Pressure gauge 56, by with the pressure through calibrating-output torque table of comparisons comparison, the output torque of equipment under this pressure can be known.Due under output pressure one stable condition, motor output torque is determined, can not transship, and therefore the output torque precision of this equipment is higher.In addition, be connected in series a reinforcement control valve 57 two gas circuits, form a bc section branch road, be responsible for unloading valve and increase output torque at need.On pinch control valve 53, handling control valve 54, be jointly connected with muffler 58, the noise produced when eliminating motor operations simultaneously.
When the present invention works, first shown in composition graphs 1, according to pressure work principle, pneumatic cylinder valve cargo handling process is described.Pressure work principle needs to realize three processes.
One is realize body clamping process, and pinch control valve 53 is switched to upper, and compression cylinder 21 is descending, clamps gas cylinder, and when preventing charge and discharge valve, gas cylinder self rotates; Load and unload control valve 54 in this process and be switched to meta, air motor 33 does not work.
Two is realize pneumatic dress valve process, and reinforcement control valve 57 is switched to bottom, disconnects pressure piping bc section branch road, handling control valve 54 is switched to bottom, air motor 33 reverses, and realizes the assembling function of cylinder valve, regulates the pressure regulator valve 55 in corresponding gas circuit electrodelessly can regulate the acrotorque filling valve.The rotating speed of air motor 33 can also be regulated by the aperture controlling handling control valve 54, guarantee the stationarity filling valve process.
Three is realize pneumaticly unloading valve process, and handling control valve 54 is switched to upper, and air motor 33 rotates forward; When air motor 33 output torque is inadequate, when cannot unload cylinder valve, reinforcement control valve 57 is switched to upper, and conducting pressure piping bc section branch road, makes larger air pressure CD-ROM drive motor 33, export larger moment of torsion, realize the offloading functions of cylinder valve.
Shown in Fig. 2, Fig. 3, be embodiment with cargo handling process, implementation procedure of the present invention is described.Alignment jig 31 docks with cylinder valve.Pinch control valve 53 is switched to upper, and pressure head 22 moves downward, clamping body.Switching handling control valve 54 is in upper, and air motor 33 rotates forward, and realizes cylinder valve offloading functions; Reinforcement control valve 57 is switched to and upperly can effectively improves unloading moment of torsion.In like manner, handling control valve 54 is switched to bottom, reinforcement control valve 57 is switched to bottom simultaneously, and air motor 33 reverses, and realizes cylinder valve assembling function.
In above-described embodiment, when the gas cylinder of concrete loading valve different-diameter, need the lengthwise position of alignment jig.Worm-and-wheel gear 41 in Fig. 4, by forward (or reverse) rotation hand wheel 6, worm screw 412 forward (or reverse) is driven to rotate, thus drive worm gear 411 forward (or reverse) to rotate, be connected in screw rod on worm gear 412 also along with rotation, by screw-driven between threaded rod and pneumatic motor framework 43, because worm gear 412 lengthwise position is constant, thus make motor bracket 43 passive upwards (or downward) motion, realize lengthwise position regulatory function.When unloading (or install) cylinder valve, thread screws out (or precession) gas cylinder, and the lateral separation generation relative changes of cylinder valve and body, devises dovetail groove 42 as moving sets for this reason, can change along with the change of cylinder valve and body lateral separation.
Above-described embodiment only illustrates inventive concept of the present invention for explaining, but not the restriction to rights protection of the present invention, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should fall into protection scope of the present invention.
