Boom 7 uses reduced pipe folding mode, is all made of night bolt between the reduced pipe that is connected and fixes, and bottom and column 5 are cut with scissors It connects.

The setting of sunpender 6 is in 7 bottom outside of boom, hingedly with boom 7.

Wirerope 32 is wound on cable wire lifting capstan winch；Wirerope 32 passes through the through-hole reserved on shell 10, is set Multiple pulleys on boom 7 are connected with suspension hook 33.

As shown in Figure 3 and Figure 4, inertia locking mechanism 9 includes shell 10, fixed stop 11, mounting plate 12, mobile block 13, damping spring 14, bearing 15, gear 16, fixing screws 17, runner 18, centrifugal-block 19, returning spring 20 and washer 21；Outside Shell 10 is the hollow cylinder with aperture, and surface is provided with shell fixing threaded hole 22, and inner containment cable wire goes up and down capstan winch；Shell is solid Determine screw hole 22 to match with bearing fixed seat fixing threaded hole, fixing bearing fixing seat can be played the role of；Fixed stop 11 has more It is a, it is arranged at the inside of shell 10；Mounting plate 12 is arranged inside shell 10, and there are gaps between fixed stop 11, are Hollow cylinder；Mobile block 13 is arranged on mounting plate 12, is connected by damping spring 14 with fixed stop 11；Damping spring 14 play the thickness for reducing the anti-born inertia locking mechanism 9 of seat, so as to the part for making full use of seat crane transmission shaft to leak outside； Bearing 15 is fixed on bearing fixed seat, is arranged in 10 tapping of shell, outside is connected with shell 10,12 phase of inside and mounting plate Even；Gear 16 is round internal gear, is provided with fixing screw hole 23；Fixing screws 17 match with fixing screw hole 23, are used for Connection gear 16 and mounting plate 12；The setting of runner 18 is provided with locating slot 24 and transmission shaft through-hole 25 in 16 inside of gear, centre； Transmission shaft through-hole 25 and the transmission shaft of cable wire lifting capstan winch match；Runner 18 by with the matched fastening screw of locating slot 24 with The transmission shaft that cable wire goes up and down capstan winch is connected；One end of centrifugal-block 19 and the tooth socket of gear 16 match, and horizontal symmetrical setting is turning The two sides of wheel 18, there are gaps between mounting plate 12, are flexibly connected by pin with runner 18；20 both ends of returning spring difference It is connected with runner 18 and centrifugal-block 19；Centrifugal-block 19 is the measurement component of impression transmission axis angular rate, it and returning spring 20 Collective effect plays a key role the function realization of the born inertia locking mechanism of anti-seat 9；Washer 21 is circular ring shape, setting Between mounting plate 12 and runner 18.

Movable supporting 28 uses the bolt of T20 × 6；Non-slipping block supporting surface is φ 80 round.

It is provided with disk handle 1 on cable wire capstan winch, drives 300 χ 50 of φ to twist using 2:25 or 1:40 transmission ratio screw thread pair Disk；Cable wire lifting capstan winch is connected with one 34 axis of disk handle.

Disk handle 2 35 is provided on 3 operating side of cyclotron mechanism, ontology uses steel ball (Φ 16) circular orbit slot (350) It for track, is driven with gear pair, bevel gear deflecting drives rotating seat 2 to rotate；Bevel gear is connected with 2 35 axis of disk handle.

Wirerope 32 is 4 lifting specialized wire rope of Φ；Crampon 33 is 3T dedicated crampons；Crane uses Φ Counterweight of 100 shot as 32 stabilising arrangement of wirerope.

In use, user is come by operation rotation of the disk handle 1 with running wire capstan winch and inertia locking mechanism 9 32 folding and unfolding of wirerope is driven, the height of ejector seat is controlled.

During rising on the seat, runner 18 is rotated counterclockwise, because centrifugal-block 19 is acted on by centrifugal force, so that from Heart block 19 is closed at always inside runner 18, does not interfere with seat lifting operations.

During seat normally declines, runner 18 is rotated clockwise, and since the speed of height of seat decline is slower, is passed Moving axis drives the angular speed of runner rotation smaller, and the centrifugal force that centrifugal-block 19 is subject to is also smaller, and centrifugal-block 19 is in returning spring 20 Under the action of close inside runner 18, the step-down operation not influenced.

When seat declines suddenly for some reason or when decrease speed is too fast, the centrifugal force that centrifugal-block 19 is subject to increases Greatly, the strength of returning spring 20 is overcome to be turned out from the inside of runner 18 around pin, moving out for centrifugal-block 19 will certainly It interacts with the internal tooth of gear 16, band moving gear 16 is rotated to the same direction, and gear 16 passes through fixing screws 17 and mounting plate 12 are connected, and mounting plate 12 also rotates in same direction, the meeting compression shock absorption spring 14 of mobile block 13 of mounting plate 12, due to damping spring 14 other end is by 10 inside fixed stop of shell, 11 restraint, and after damping spring 14 is sufficiently compressed, the decline of seat is also immediately Stop.

Locking of the inertia locking mechanism 9 to seat is released, as long as the rocker arm of seat crane is turned along seat ascent direction Dynamic 1/4 circle decontrols engaging between 16 internal tooth of gear and centrifugal-block 19, and centrifugal-block 19 is taken under the action of returning spring 20 to be turned In wheel 18, so that it may continue to use operation of the crane to seat.

Compared with prior art, the utility model discloses one kind to prevent born tilting seat crane, is provided with inertia and closes Latch mechanism can timely and effectively carry out seat in shortest time minimum dropping distance when seat occurs without control decline Braking, while avoiding because of equipment damage or bring adversely affects due to casualties, safety is good；Crane operation is simple, volume It is smaller, using reliable.

Although the utility model is illustrated and described with regard to preferred embodiment, those skilled in the art should be managed Solution, without departing from the claim limited range of the utility model, the utility model can be carried out various change and Modification.
