Detailed description of the invention
With embodiment, the present invention is described further below in conjunction with the accompanying drawings.Although the present invention will be described in conjunction with preferred embodiment, it should be understood that be not offered as limiting the invention in described embodiment.On the contrary, the present invention will contain alternative, modified model and the equivalent that can be included in the scope of the present invention that appended claims limits.
Referring to figs. 1 through shown in Fig. 7, the pneumatic releasing structure of ground wire operating lever of the present embodiment, ground wire operating lever upper end body 1 is internal equipped with push-rod piston 2, and earth lead pneumatic operation end is made up of operating side body 3, piston 4, sincere sub 5 and energy-stored spring 6 four part；Body 1 is made up of earth lead termination draw-in groove 1-1, outer wall 1-2, powerful permanent ferrum 1-3 and air flue 1-4；Push-rod piston 2 is made up of push pedal 2-1, connecting rod 2-2 and piston 2-3；Operating side body 3 is made up of operation terminal interface 3-1, operating side air chamber 3-2, sincere pilot trench 3-3；Piston 4 is made up of piston only 4-1, sincere sub-stopper slot 4-2, piston rod 4-3 and energy storage handle 4-4；Sincere sub 5 are made up of sincere sub-head 5-1, sincere son vertex 5-2, action bars 5-3 and error preventing lock 5-4；Energy-stored spring 6 is made up of energy-stored spring 6.
Earth lead 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 ferrum, 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 is fixed as one by connecting rod 2-2 with piston 2-3.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 sincere pilot trench 3-3.
Piston 4 upper end has a cylinder housing piston only 4-1, sincere sub-stopper slot 4-2 to be the semicircular ring along piston only 4-1 damaged surface intermediate vertical axle center,
Sincere sub 5 is multi-link structure, it is cylinder in the middle of the most sincere sub-head 5-1, one is hemisphere, and the other end is connected with action bars 5-3, and sincere son vertex 5-2 is the corner block being fixed on operating side body 3, it is connected with action bars 5-3, action bars 5-3 can rotate around the little scope of sincere son vertex, drives sincere sub-head 5-1 turnover motion, and error preventing lock 5-4 is with Elliptic Cylinder, it is connected with action bars 5-3, rotatably.
Operation principle and process:
Normal operating conditions, earth lead termination is held by permanent magnet 1-3 with powerful captivation, and permanent magnet 1-3 is contacted by push pedal 2-1 with earth lead termination；Pull downward on energy storage handle 4-4, piston only 4-1 is made to move downward by piston rod 4-3 transmission, compressed energy-storage spring 6 stores potential energy simultaneously, completes thermal energy storage process when sincere sub-head 5-1 slips into sincere sub-stopper slot 4-2, and sincere sub-head 5-1 blocks sincere sub-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 lead is departed from by needs with action bars, error preventing lock 5-4, using compressed air as power, can be transferred to as power by the present invention with spring-compressed, inwardly pressing operations bar 5-3, due to the leverage of sincere son vertex 5-2, sincere sub-head 5-1 moves out along sincere pilot trench 3-3, and now piston only 4-1 loses brake force, energy-stored spring 6 releases energy, promoting piston only 4-1 to move upward, in making operating side air chamber 3-2, gas compression moves upward, and completes to export the purpose of pneumatic energy；Compressed air enters cylinder by air flue 1-4, promotes piston upwards, promotes push pedal 2-1 and earth lead termination to move upward with connecting rod simultaneously, and earth lead termination to going out action bars upper end, is completed earth lead termination and action bars departs from operation by push pedal 2-1.
As shown in Figure 3.State 1: initial final state, due to the suction-combining force, push pedal 2-1 is pressed downward against by earth lead termination, makes push pedal 2-1 contact with permanent magnet 1-3, and piston 2-3 is in extreme lower position.Energy-stored spring 6 energy has discharged,
As shown in Figure 4.State 2: pull downward on energy storage handle 4-4, piston only 4-1 is made to move downward by piston rod 4-3 transmission, compressed energy-storage spring 6 stores potential energy simultaneously, complete thermal energy storage process when sincere sub-head 5-1 slips into sincere sub-stopper slot 4-2, sincere sub-head 5-1 blocks sincere sub-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 SBR.Error preventing lock 5-4 is transferred to, can operate the most at any time.
As shown in Figure 6.State 4: operation.Inwardly pressing operations bar 5-3, due to the leverage of sincere son vertex 5-2, sincere sub-head 5-1 moves out along sincere pilot trench 3-3, owing to compressed gas enters cylinder by air flue, promoting piston 2-3 to move upward, piston 2-3 promotes push pedal 2-1 and earth lead termination to move upward by connecting rod 2-2..
As shown in Figure 7.State 5: state 4 premise lower piston body 4-1 loses brake force, and energy-stored spring 6 releases energy, promotes piston only 4-1 to move upward, and in making operating side air chamber 3-2, gas compression moves upward, and completes to export the purpose of pneumatic energy.Action bars upper end is released in earth lead termination by push pedal 2-1, and piston 2-3 is positioned at top.Earth lead termination has separated with action bars upper end.Then recover state 1.
