Abstract

The utility model provides an erecting and unlocking mechanism for a launch box and a transport carrier, which comprises a lock pin arranged at the side of a box body, a lock pin seat, a return spring and a pin hole on the transport carrier, wherein the tail end of the lock pin is connected with a wire rope which is connected with one end of a crank round a guide pulley; the middle of the crank is articulated on the box body through a rotating shaft; and the other end of the crank is an unlocking trigger handle. When the launch box and the transport carrier are in horizontal condition, the outer included angle r of the unlocking trigger handle of the crank and the horizontal line is 90-100 degrees. The overall mechanism is arranged at the tail of the box, when the box is in horizontal condition, the lock pin is inserted in the pin hole on the carrier under the action of the spring force, so as to limit the movement of the carrier during the vehicle transportation; when the box is erected to a certain angle, the crank is in contact with a bump at the tail of the vehicle, the rotation angle of the crank is increased along with the increasing erecting angle, the moving distance of the wire rope fixed on the crank is also increased, and the lock pin is gradually pulled out of the carrier under the tensile force of the wire rope while overcoming the spring force.

Description

A kind of firing box and transport agent play perpendicular release mechanism

Technical field

The utility model relates to a kind of firing box and transport agent plays perpendicular release mechanism, belongs to frame for movement, a perpendicular lock technology of separating of particularly box transport agent rocket projectile.

Background technology

Rocket projectile (carrier) need be by lock pin with rocket projectile (carrier) and transportation casing locking in transportation, when the transportation casing rises when perpendicular, lock pin need be opened, i.e. release.When firing box rise perpendicular to 90 ° after, all releases of all rocket projectiles (carrier).

The transport agent release mainly is directly to rely on hydraulic coupling or electric power, manual force that lock pin is extracted outside the carrier under level in traditional case, this mode of pulling pin, because the motion of carrier in transit, make between pin and the pin-and-hole and have contact force, cause the power of pulling pin very big, occur the phenomenon that lock pin can't be extracted sometimes.

Summary of the invention

The purpose of this utility model provides a kind of firing box and transport agent plays perpendicular release mechanism, and this mechanism is the thrust that indirect utilization plays perpendicular oil cylinder, and transport agent plays perpendicular process in case, and lock pin is extracted outside the carrier automatically.

The technical solution of the utility model: firing box of the present utility model and transport agent play perpendicular release mechanism and comprise pin-and-hole on lock pin, locking pin seat, return spring and the transport agent that is installed in the casing side, it is characterized in that: the tail end of lock pin connects steel wire rope, steel wire rope is walked around directive wheel and is connected with an end of crank, and the middle part of crank is hinged on the casing by rotating shaft; The other end of crank is that release triggers handle.

Described firing box and transport agent play perpendicular release mechanism, and when firing box and transport agent were in level, the release of crank triggered handle and angle r=90 °～100 ° at horizontal line outward.

Described firing box and transport agent play perpendicular release mechanism, and the trigger end that the release of crank triggers handle is on the same circular arc in the center of circle with being fixed on that projection on the car launcher is positioned at the gyroaxis.

Advantage of the present utility model: the utility model has solved box transport agent release problem, release mechanism is simple, reliable, easy to implement, its advantage is: 1) existing perpendicular cylinder thrust on the indirect utilization vehicle do not need to add in addition special power set; 2) release is selected in carrier opportunity and rises in the perpendicular vertical process, releasing force minimum, the big problem of releasing force when having overcome horizontal release; 3) be convenient to a plurality of carriers of release simultaneously.

Description of drawings

Fig. 1 is the schematic diagram of release mechanism of the present utility model.

Fig. 2 is that release mechanism casing of the present utility model works release mechanism schematic diagram when erecting.

The specific embodiment

Below in conjunction with accompanying drawing and example structure of the present utility model is described in further detail.

Among the figure: the 13rd, car launcher, the 10th, play vertical beam, the 11st, casing, the 12nd, carrier.12a is the pin-and-hole on the transport agent 12.Locking pin seat 2 is fixed on the casing 11, and lock pin 1 and return spring 3 are in locking pin seat 2.The tail end of lock pin 1 connects steel wire rope 5, and steel wire rope 5 is walked around directive wheel 4 and is connected with an end of crank 6, and the middle part of crank 6 is hinged on the casing by rotating shaft 7; The other end of crank 6 is that release triggers handle 6a.

When firing box and transport agent are in level, outer angle r=90 °～100 ° of the release triggering handle 6a of crank 6 and horizontal line, after guaranteeing that release triggers handle 6a and the projection 8 of car launcher afterbody contacts, release triggers handle 6a and clockwise rotates, pulling steel wire rope 5.To be positioned at gyroaxis 9 be on the same circular arc in the center of circle to the trigger end that the release of crank 6 triggers handle 6a with being fixed on projection 8 on the car launcher.

As Fig. 1: in transportation, promptly casing 11 and carrier 12 are in level, because the effect of return spring 3, lock pin 1 puts in the pin-and-hole 12a on the carrier 12, with carrier and the locking of transportation casing, keep stable.

As Fig. 2: rise when perpendicular, casing 11 and transport agent 12 are holded up with playing a vertical beam 10 on a vertical beam 10, when casing and transport agent perpendicular during to certain angle, release triggers handle 6a and contacts with the projection 8 of car launcher afterbody, along with casing and transport agent continue to hold up,

release triggers handle

6a and 7 rotated around the shaft by the resistance of projection 8, and the other end of crank 6 produces pulling force to steel wire rope 5, overcome spring force, lock pin 1 is extracted outside the carrier.As long as when design, when guaranteeing that casing 11 and transport agent 12 are vertically, the distance of crank 6 pulling steel wire ropes 5 is greater than the degree of depth of pin-and-hole 12a, just can work when erecting to 90 ° safe release at firing box.

When firing box rise perpendicular during to 90 °, the carrier 12 release, crank 6 by being arranged on the spring catch of casing side, is locked in maximum rotated position with crank 6 after release puts in place simultaneously, inserts in the carrier to guarantee that lock pin 1 can not rebound again.

Sleeve mechanism is installed in the case afterbody, and case is when level, and lock pin is inserted under the effect of spring force in the pin-and-hole on the carrier, with the motion of restriction carrier when the vehicle transport; When case rises perpendicularly during to certain angle, crank is with after the projection of the tailstock portion contact, along with a vertical angle degree increase, the crank anglec of rotation also increases, and is fixed on the distance that the steel wire rope on the crank moves and also increases, and lock pin is subjected to pull of steel wire, overcome spring force, extracted outside the carrier gradually.
