Due to the fact that the double-locking structure with the pawl and the lock pin is adopted by the double-insurance lock, a guarantee is provided for safety of a tourist, and the double-insurance lock has the advantages of being convenient to use, safe and reliable.
Description
Technical field
The present invention relates to a kind of locking device of large-scale recreation facility standing posture passenger cabin, be specifically related to a kind of lockset of dual fail-safe.
Background technology
In large-scale recreation facility, passenger cabin is the main carriers that visitor takes, and passenger cabin is divided into sitting posture passenger cabin and standing posture passenger cabin, and visitor needs after entering into passenger cabin to carry out spacing with pressure thick stick, to ensure the safety of visitor.Because the structure of standing posture passenger cabin is different from the structure of sitting posture passenger cabin, thus the pressure thick stick lockset of sitting posture passenger cabin is not suitable for using on standing posture passenger cabin.Existing standing posture passenger cabin lockset adopts common locking mode, poor safety performance, once lockset damages, will threaten the personal safety of visitor.
Summary of the invention
In order to overcome the deficiency of existing standing posture passenger cabin lockset safety performance difference, the invention provides a kind of lockset of dual fail-safe, the lockset of this dual fail-safe adopts the structure of ratchet and lock pin double locking, for the safety of visitor provides guarantee, has easy to use and safe and reliable feature.
Technical scheme of the present invention is: a kind of lockset of dual fail-safe comprises outrigger, outrigger is provided with pulley and support, support runs through and is provided with ratchet and wheel carrier, and ratchet and wheel carrier are equipped with spring, and spring has the elasticity trend that ratchet and wheel carrier are moved down; The top of support is provided with adjustable shelf, described adjustable shelf is fixed shank and lock pin, adjustable shelf is connected with drag-line, guy cable rounds pulley is connected with operation handwheel, the upper end of ratchet and the lower end of shank are provided with suitable grab, and the upper end of wheel carrier is wedge shape and corresponding with the transverse axis in push pedal; The below of support is provided with ratchet bar, and the bottom surface of ratchet bar is provided with lock hole, and the lower end of ratchet can be meshed with ratchet bar, and lock pin can penetrate in lock hole.
Described outrigger is fixed with spacing catch.
Described outrigger is fixed with upper stroke switch and lower stroke switch, upper stroke switch is corresponding with adjustable shelf, and lower stroke switch is corresponding with ratchet bar lower surface.
The lower end of described ratchet bar is provided with running roller.
The present invention has following beneficial effect: owing to taking technique scheme, have employed the structure of ratchet and lock pin double locking, for the safety of visitor provides guarantee, easy to use, safe and reliable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Shown in Fig. 1 composition graphs 2, Fig. 3, Fig. 4, a kind of lockset of dual fail-safe comprises outrigger 1, outrigger 1 is provided with pulley 2 and support 3, support 3 runs through and is provided with ratchet 4 and wheel carrier 5, ratchet 4 and wheel carrier 5 are equipped with spring 6, and spring 6 has the elasticity trend that ratchet 4 and wheel carrier 5 are moved down; The top of support 3 is provided with adjustable shelf 7, described adjustable shelf 7 is fixed shank 8 and lock pin 9, adjustable shelf 7 is connected with drag-line 10, drag-line 10 is walked around pulley 2 and is connected with operation handwheel, the upper end of ratchet 4 and the lower end of shank 8 are provided with suitable grab 11, and the upper end of wheel carrier 5 is wedge shape and corresponding with the transverse axis in push pedal 12; The below of support 3 is provided with ratchet bar 13, and the bottom surface of ratchet bar 13 is provided with lock hole 14, and the lower end of ratchet 4 can be meshed with ratchet bar 13, and lock pin 9 can penetrate in lock hole 14.Owing to taking technique scheme, during use, outrigger 1 is fixed on passenger cabin, ratchet bar 13 is connected on pressure thick stick, visitor fastens pressure thick stick after entering passenger cabin, ratchet bar 13 penetrates in lockset from the below of ratchet 4 and wheel carrier 5, the wheel of wheel carrier 5 lower end moves up under the progradation of ratchet bar 13, the upper end of wheel carrier 5 drives push pedal 12 to be moved to the left, push pedal 12 by the head of ratchet 4 toward left translation, ratchet 4 is departed from the grab 11 of shank 8, ratchet 4 moves down and is meshed with ratchet bar 13 under the effect of spring 6, now ratchet bar 13 is locked by ratchet 4, can only unidirectional propelling can not retreat, define first insurance, when ratchet bar 13 enters certain distance, then rotating operation handwheel, drag-line 10 loosens, and adjustable shelf 7 moves down, and lock pin 9 is inserted in lock hole 14, result in formation of second insurance, meanwhile, shank 8 also move down and with ratchet 4 phase card, lockset now pins completely.When opening lockset, rotating operation handwheel, is mentioned adjustable shelf 7 by drag-line 10, disposablely ratchet 4 and lock pin 9 are pulled up completely, pull-out ratchet bar 13, in ratchet bar 13 moving process, because wheel carrier 5 does not move down, push pedal 12 is not operating, and ratchet blocks by now push pedal 12, when ratchet bar 13 skids off completely time, wheel carrier 5 is to moving down, and push pedal 12 also and then moves right, and ratchet 4 is raised to peak, lockset is opened completely, and all parts is returned to original position.Present invention employs the structure of ratchet 4 and lock pin 9 double locking, for the safety of visitor provides guarantee, easy to use, safe and reliable.
Described outrigger 1 is fixed with spacing catch 15.Spacing catch 15 limits adjustable shelf 7 by the extreme higher position promoted, and avoids the lower end of ratchet 4 to be retracted in support 3.
Described outrigger 1 is fixed with upper stroke switch 16 and lower stroke switch 17, upper stroke switch 16 is corresponding with adjustable shelf 7, and lower stroke switch 17 is corresponding with ratchet bar 13 lower surface.Upper stroke switch 16 and lower stroke switch 17 gather locking and unlocking signal, and feed back to operating console, avoid maloperation.
The lower end of described ratchet bar 13 is provided with running roller 18.Running roller 18 pairs of ratchet bars 13 play and support and spacing effect, and when ratchet bar 13 advances or pulls out, running roller 18 rolls, and frictional resistance is little, and ratchet bar 13 advances or pull out laborsaving.
