Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Consult Fig. 1, an embodiment of the present invention safety pin 100 comprises cylinder 1, piston 2, latch 3, pressurized air supplier 4, position regulating device 5, selector valve 7 and support 8.
Cylinder 1 is provided with first interface 11 and the second interface 12.Piston 2 to be arranged in cylinder 1 thus cylinder 1 is divided into the first cavity 13 and the second cavity 14 along first direction X; First interface 11 is communicated with the first cavity 13, second interface 12 and is communicated with the second cavity 14.Latch 3 is fixed on piston 2.
In order to increase the stroke of latch 3 on first direction X, and then promote the Safety performance adopting safety pin 100 locking device 6, preferably, first interface 11 and the second interface 12 are located at cylinder 1 and are positioned at two ends on first direction X.In the present embodiment, preferably, the cross section of cylinder 1 is ring, and namely the cross section of the first cavity 13 and the second cavity 14 is circular, and the cross section of piston 2 also be circle, so arranges, and can obtain the first cavity 13 and the more excellent sealing effect of the second cavity 14.
Position regulating device 5 for along perpendicular to the position of the second direction Y adjusting cylinders 1 of first direction X, makes latch 3 can at multiple locking position equipment 6 to be locked.It should be noted that, equipment 6 to be locked can be a concrete equipment, can also be the multiple devices being distributed in diverse location along second direction Y.
Position regulating device 5 comprises mounting platform 51, traction gear 52, drive unit 53 and guide rail 54.Cylinder 1 is fixed to mounting platform 51.Traction gear 52 connection platform 51 also adjusts the position of mounting platform 51 along second direction Y under the driving of drive unit 53.
In the present embodiment, first direction X is substantially horizontal, and second direction Y is vertical direction.Traction gear 52 is rope, and drive unit 53 is motor or motor.Under the driving of drive unit 53, rope pulls mounting platform 51 and cylinder 1 synchronously rise or decline.Guide rail 54 is arranged along second direction Y, and mounting platform 51 along the guiding being subject to guide rail 54 in second direction Y moving process, thus guarantees that mounting platform 51 is stable mobile, and then guarantees that cylinder 1 and latch 3 deflection can not occur on horizontal or vertical direction.
Pressurized air supplier 4 can supply pressurized air to the first cavity 13 by first interface 11, or supplies pressurized air to the second cavity 14 by the second interface 12, to promote piston 2 and to be fixed to the latch 3 of piston 2 along first direction X to-and-fro motion.
In the present embodiment, selector valve 7 is solenoid directional control valves of two-position four-way.Selector valve 7 is provided with the 3rd interface 71, the 4th interface 72, intake interface P and exhaust port T.3rd interface 71 is communicated with first interface 11, and the 4th interface 72 is communicated with the second interface 12, and intake interface P connects pressurized air supplier 4.3rd interface 71 and the 4th interface 72 are optionally communicated to intake interface P and exhaust port T by selector valve 7.
In the present embodiment, pressurized air supplier 4 is fixed to mounting platform 51 with selector valve 7 together with cylinder 1.In practical application, pressurized air supplier 4 and selector valve 7 can also be arranged on other positions outside mounting platform 51.
The working principle of selector valve 7 is please with reference to Fig. 2.When the 3rd interface 71 is communicated to intake interface P by selector valve 7 under the first N state of energising, and the 4th interface 72 is communicated to exhaust port T; When under the second state F of selector valve 7 in power-off, the 3rd interface 71 being communicated to exhaust port T, and the 4th interface 72 is communicated to intake interface P.
Support 8 to be arranged in parallel multiple through hole 81 along second direction Y, is supported through a wherein through hole 81 at diverse location for the latch 3 along second direction Y movement by support 8; Thus strengthen the locking guarantee that safety pin 100 treats locking device 6.
Please with reference to Fig. 3 and Fig. 4, apply the step that safety pin 100 of the present invention locks equipment to be locked as follows: drive traction gear 52 to pull mounting platform thus precalculated position on adjustment cylinder 1 and latch 3 to second direction Y along second direction Y by drive unit 53.Now, selector valve 7 is in the second state F of power-off; Latch 3 is with wherein a through hole 81 is corresponding.In this case, the pressurized air supplied from compression air feeder 4 enters the second cavity 14 from intake interface P by the second interface 12 and the 4th interface 42, making the pressure of the second cavity 14 be greater than the first cavity 13 makes piston 2 that latch 3 can not be driven to move towards the second cavity 14, now, latch 3 non-locking equipment 6 to be locked and latch 3 are positioned at outside through hole 81.
Then, selector valve 7 is opened, under making selector valve 7 be in the first N state of energising.In this case, the pressurized air supplied from compression air feeder 4 enters the first cavity 13 from intake interface P by first interface 11 and the 3rd interface 71, and the pressure of the first cavity 13 is increased gradually.Now, the second cavity 14 is communicated with exhaust port T by the second interface 12, the 4th interface 72.When the pressure of the first cavity 13 is greater than the second cavity 14, piston 2 drives latch 3 to move towards the second cavity 14, and the volume of the first cavity 13 becomes large gradually, and the volume of the second cavity 14 diminishes gradually; Latch 3 penetrates corresponding through hole 81 and is supported by support 8, and on first direction X, exceeds support 81 and then lock device is treated in locking.
When the equipment 6 locked by latch 3 needs to unlock, only need selector valve 7 power-off, now selector valve 7 is in the second state F, and in this case, latch 3 and equipment 6 to be locked unlock and do not supported by support 8 on first direction X.
Compared with prior art, safety pin 100 of the present invention adopts latch to be fixed to piston, the cavity of cylinder is divided into two by piston, and pressurized air injects cylinder thus promotion latch contraction arrival plugs automatically or the function of Contractible safety pin, eliminates the potential safety hazard manually plugging safety pin; And the present invention by the position of position regulating device 5 adjusting cylinders 1 to meet the object that multiple different position plugs safety pin.
In addition to the implementation, safety pin of the present invention can also make following change: such as, and selector valve 7 adopts three position four-way directional control valve; Or support 8 is fixed to mounting platform 51, and a through hole corresponding with latch 3 is only set makes support 8 and cylinder 1 along second direction Y synchronizing moving etc.
The foregoing is only embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
