Abstract
The invention discloses a connecting and releasing device utilizing a separation nut. The connecting and releasing device is used for connecting and releasing two detached bodies and comprises the separation nut, a gasket, a cylindrical spring, a lock nut, a collecting box and an anti-shear taper sleeve. The separation nut comprises a screw stem, and the collecting box is arranged above the separation nut. The anti-shear taper sleeve is fixedly mounted on an abutting frame of a support chamber between the two detached bodies. The screw stem penetrates the two detached bodies, the gasket and the cylindrical spring sequentially and is locked by the lock screw, so that the two detached bodies are connected. By means of separation of the separation nut, the separated screw stem and the lock nut are pushed into the collecting box by the cylindrical spring, so that the two detached bodies are released without any spatial redundancy. Reliability in separation of the two detached bodies is guaranteed by spherical-surface matching between the lock nut and the gasket.

Preferably, for sphere cooperates, this sphere is equipped with has the certain clearance compensate function between described locking nut and the described pad, guarantees the reliability of separating.
Preferably, described shearing resistance tapered sleeve is fixedly connected on the interface frame, mating frame that supports the cabin in described two detached bodys, because separation nut is difficult for bearing shearing, is then born the cross shear of separating interface by the shearing resistance tapered sleeve.
Preferably, described cylindrical spring has certain pretightening force, and the screw rod after keeping separating does not shake in described collection box, and collects box screw rod is collected, and avoids producing more space fifth wheel.
Preferably, described separation nut is ripe firer's element, and described locking nut and described pad are the common metal part, and the separation nut of firer's element has very high reliability, and its material is not as limit.
A kind of separation nut connects dislock method, utilizes aforesaid separation nut to connect tripper two detached bodys are connected and release, and its concrete steps comprise:
1) at first, two detached bodys are docked, the shearing resistance tapered sleeve is installed on the interface frame, mating frame that supports the cabin in two detached bodys, separation nut is installed, screw rod is passed the shearing resistance tapered sleeve, and install pad, cylindrical spring and locking nut, and adopt the many locking nuts of torque spanner to apply pre-fastening moment, install at last and collect box;
2) receive unlock command after, separation nut work, the screw rod after cylindrical spring will separate is bound to be collected in the box, and cylindrical spring maintains certain pretightening force, the screw rod after keeping separating does not shake in collecting box.
Compared with prior art, beneficial effect of the present invention is as follows:
1, the present invention is by adopting cylindrical spring and collecting box, and the realization screw rod springs into after realization separates and collects in the box, by cylindrical spring pretightening force fastening screw it is not shaken, and by collecting box collection screw rod and locking nut, does not produce the space fifth wheel.
2, cooperate by design spherical between locking nut of the present invention and the pad, make to have the certain clearance compensate function, guarantee the reliability of separating.
Description of drawings
Fig. 1 connects the tripper structural representation for separation nut of the present invention.
The symbol tabulation:
The 1-separation nut, 2-shearing resistance tapered sleeve, the 3-pad, the 4-cylindrical spring, the 5-locking nut, 6-collects box.
Embodiment:
Referring to the accompanying drawing that the embodiment of the invention is shown, hereinafter with more detailed description the present invention.Yet the present invention can be with realizations such as multi-form, specifications, and should not be construed as the embodiment's who is subjected in this proposition restriction.On the contrary, it is abundant and complete open in order to reach proposing these embodiments, and makes more relevant those skilled in the art person understand scope of the present invention fully.In these accompanying drawings, for clearly visible, may amplify or dwindle relative size.
Referring now to Fig. 1 describes in detail according to separation nut connection tripper of the invention process, as shown in Figure 1, separation nut provided by the invention connects tripper, comprises separation nut 1, shearing resistance tapered sleeve 2, pad 3, cylindrical spring 4, locking nut 5 and collects box 6; Separation nut 1 is provided with screw rod, collection box 6 is placed on the top of separation nut 1, by shearing resistance tapered sleeve 2 being installed on the interface frame, mating frame that supports the cabin in two detached bodys, the screw rod of separation nut 1 passes shearing resistance tapered sleeve 2 and pad 3 successively, and separation nut 1 passes cylindrical spring 4, and by locking nut 5 lockings, thereby two detached bodys are connected; And by the separating action of separation nut 1, the screw rod after cylindrical spring 4 will separate and locking nut 5 are bound to be collected in the box 6, thereby to two detached body releases, two detached bodys is separated.
Wherein, separation nut 1 in the present embodiment is ripe firer's element, has very high reliability, locking nut 5 and pad 3 are common metal parts, locking nut 5 and pad 3 is used for locking separation nut 1, realizes the reliable connection of two detached bodys, and 3 on locking nut 5 and pad cooperate for sphere, have the certain clearance compensate function, guarantee the reliability of separating.Because separation nut 1 is difficult for bearing shearing, therefore shearing resistance tapered sleeve 2 is set is fixed on the interface frame, mating frame that supports the cabin, to bear the cross shear of separating interface.
