Earth connection termination draw-in groove 1-1 is the axial groove opened on outer wall 1-2; Outer wall 1-2 is tubular overcoat, and permanent magnet 1-3 is with cylindrical magnet iron, and inside axially has penetrating circular hole, and for the moving conduit of connecting rod 2-2, permanent magnet 1-3 is fixed on outer wall 1-2 by methods such as bolts; Air flue 1-4 is a cylindrical channel on insulating bar, as gas passage.
Push pedal 2-1 is that nonferromugnetic material makes cylindrical plate; Piston 2-3 is cylindrical piston, and size is mated with outer wall, and push pedal 2-1 and piston 2-3 is fixed as one by connecting rod 2-2.Piston 2-3 and air flue 1-4 forms Simple air cylinder.
Operating side body 3 is a hollow circular cylinder, and upper end is operation terminal interface 3-1, and hollow cylinder is operating side air chamber 3-2, and opens a through-hole in its damaged surface and be pawl slot 3-3.
There is a cylinder seat piston only 4-1 piston 4 upper end, and pallet stopper slot 4-2 is the semicircular ring along piston only 4-1 damaged surface intermediate vertical axle center,
Pallet 5 is multi-link structure, be wherein cylinder in the middle of pallet head 5-1, one is hemisphere, and the other end is connected with action bars 5-3, and pallet summit 5-2 is fixed on the corner block on operating side body 3, be connected with action bars 5-3, action bars 5-3 can rotate among a small circle around pallet summit, and drive pallet head 5-1 turnover motion, error preventing lock 5-4 is with Elliptic Cylinder, be connected with action bars 5-3, rotatably.
Operation principle and process:
Normal operating conditions, earth connection termination holds with powerful attraction by permanent magnet 1-3, and permanent magnet 1-3 and earth connection termination are contacted by push pedal 2-1; Pull energy storage handle 4-4 downwards, by piston rod 4-3 transmission, piston only 4-1 is moved downward, compressed energy-storage spring 6 storage of potential energy, completes thermal energy storage process when pallet head 5-1 slips into pallet stopper slot 4-2 simultaneously, and pallet head 5-1 blocks pallet stopper slot 4-2 and keeps energy-stored spring 6 elastic potential energy.Error preventing lock 5-4 is proceeded between action bars 5-3 and operating side body 3, prevent touching action bars 5-3 by mistake and cause unexpected releasing energy.
When earth connection and action bars depart from by needs, error preventing lock 5-4, using compressed air as power, for power, can transfer to spring-compressed by the present invention, inside pressing operations bar 5-3, due to the leverage of pallet summit 5-2, pallet head 5-1 outwards moves along pawl slot 3-3, and now piston only 4-1 loses braking force, energy-stored spring 6 releases energy, promote piston only 4-1 to move upward, gas compression in the air chamber 3-2 of operating side is moved upward, complete the object exporting pneumatic energy; Compressed air enters cylinder by air flue 1-4, promotes piston upwards, moves upward with connecting rod promotion push pedal 2-1 and earth connection termination simultaneously, and earth connection termination to going out action bars upper end, is completed earth connection termination and action bars disengaging operation by push pedal 2-1.
As shown in Figure 3.State 1: initial state of termination, due to the suction-combining force, earth connection termination is by push pedal 2-1 to pressing down, and push pedal 2-1 is contacted with permanent magnet 1-3, and piston 2-3 is in extreme lower position.Energy-stored spring 6 fault offset completes,
As shown in Figure 4.State 2: pull energy storage handle 4-4 downwards, by piston rod 4-3 transmission, piston only 4-1 is moved downward, compressed energy-storage spring 6 storage of potential energy simultaneously, complete thermal energy storage process when pallet head 5-1 slips into pallet stopper slot 4-2, pallet head 5-1 blocks pallet stopper slot 4-2 and keeps energy-stored spring 6 elastic potential energy.Error preventing lock 5-4 is proceeded between action bars 5-3 and operating side body 3, prevent touching action bars 5-3 by mistake and cause unexpected releasing energy.
As shown in Figure 5.State 3: operation standby condition.Error preventing lock 5-4 is transferred to, now can operate at any time.
As shown in Figure 6.State 4: operation.Inside pressing operations bar 5-3, due to the leverage of pallet summit 5-2, pallet head 5-1 outwards moves along pawl slot 3-3, because Compressed Gas enters cylinder by air flue, promote piston 2-3 to move upward, piston 2-3 promotes push pedal 2-1 by connecting rod 2-2 and earth connection termination moves upward.。
As shown in Figure 7.State 5: state 4 prerequisite lower piston body 4-1 loses braking force, and energy-stored spring 6 releases energy, promotes piston only 4-1 and moves upward, gas compression in the air chamber 3-2 of operating side is moved upward, complete the object exporting pneumatic energy.Action bars upper end is released in earth connection termination by push pedal 2-1, and piston 2-3 is positioned at top.Earth connection termination has been separated with action bars upper end.Then return to form 1.
