Description

The invention relates to mechanisms for marine, space and ground research, as well as for equipping marine, land and air vehicles.

The purpose of the invention is to increase reliability, improve performance by separating parts of the vehicle,

In Fig, 1 shows the proposed device, a longitudinal section; in fig. 2 - holding, cross section, - in fig. 3 - actuator (option 1), a longitudinal section; in FIG. 4 - the same (option 2), a longitudinal section; in FIG. 5 - device with open grippers, a longitudinal section.

The device for connecting the split parts 1 and 2 of the vehicle consists of a housing 3 with an actuator 4 kinetically connected to two grippers 5 and 6, spring-loaded springs 7. The grippers 5 and 6 at one end are connected with the hinges 8 to the separated part 2 of the vehicle, and on the other end of the grippers 5 and 6, protrusions 9 and 10 are made with abutment surfaces 11 and 12 which are in contact with the contact pads 13 and 14 on the separating parts of the 1TC.

The grooves 15 are made on the protrusions 9 (see Fig. 2), and the grooves 16 are made on the protrusions TO, which have thrust inclined platforms 17 and 18, respectively, mating with the surfaces 19 and 20 of the Z-shaped bars 21.

Each Z-bar 21 has a slope of 22; which mates with a slope 23 of the retaining plate 24, wherein a protrusion 25 is made above the inclination 22, the longitudinal dimension of which exceeds the transverse dimension of the retaining plate 24, i.e. its outer edge protrudes beyond the size of the bar 24.

The actuating element 4 (see Fig. 1) comprises a hollow body 26 (see Fig. 3), inside which an element 27 of material with shape memory is placed, during heating of which its length increases. A power element 28 is fixed to the housing 26, having a groove 29 forming a zone of weakened cross-section. Threaded section

30 power element 28 with a nut

31 connects the strip 24 to the power element 28. A rod 32 is placed between the groove 29 of the weakened section zone and the element 27, the element 27 is made tubular, the heaters 33 are placed inside and outside it. The element 27 can also be made of material (see FIG. .4), a spontaneously changing physical state.

The device operates as follows,

When connecting the separable parts 1 and 2 (see Fig. 5), the grippers 5 and 6 are lowered so that the protrusions 9 and 10 with the supporting pads are in contact with the contact pads 13 and 14. Then the Z-shaped strips 24 are inserted (see Fig. 2), into the grooves of the protrusions 18 and 19. Under the Z-shaped strips 24, a stop bar 27 is brought in so that the slopes 25 are aligned with the slopes 26. The stop bar 27 is connected to the actuator 4 (in Fig. 3 this is a screw connection), At the same time, the strips 24 have protrusions 28 that surround the stop plate 27, increasing the reliability of the connection no.

The springs 7 (see Fig. 5) create a moment of force Regarding the hinges 8 on the grips 5 and 6. The moment of force tries to return the grippers 5 and 6 to the initial position, i.e. expand them. The force of the moment of the springs 7 is transmitted to the Z-shaped strips 24 through the surfaces in contact with the grippers 5 and 6 as a tensile force, which, due to the perpendicularity of the surfaces to which the force acts, decomposes according to the parallelogram method, as a result of which the tensile force is transverse force, the latter - causes an increase in the efficiency of the hinge of the Z-shaped strips 24 (see Fig. 2). Through the Z-shaped strips 24, the force is transmitted to the abutment plate 27. Since the surfaces of the Z-shaped strips 24 in contact with the surfaces of the abutment plate 27 are relative to the axis of rotation, which passes through the threaded section 33 (see FIG. 3) of the power element 31 with a nut 34, symmetrically, which provides balancing of the moments acting on the slopes 26 (see Fig. 2) of the retaining plate 27. As a result, the slopes 26 are affected only by the force, which, decomposed by the parallelogram method, acts as moments on weakened zone 32 (see Fig. 3) of the power element 31 in two directions, thereby reducing the area 32 of the weakened cross-section, since each moment is less than the conditional moment that would act under the direct, i.e. directed perpendicular to the acting force, slopes 21 (see Fig. 2),

As a result of the interaction of the Z-shaped strips 24, the thrust inclined pads 20 and the thrust film 27, a reliable lock is formed that holds the grips 5

and 6 (see Fig. 1) in the closed position, which reliably holds the separable parts of the Ki 2 TC in the connected state.

If it is necessary to disconnect the divided parts 1 and 2 of the vehicle, a signal corresponding to the device of the element 30 is supplied to the actuating element A. Next, consider the embodiment shown in FIG. 3, in which the element 30 is made using a material with a shape memory effect. In this case, the signal is the electric current that is supplied to the heaters 36. The heaters heat the element 30, which, increasing in length, acts on its end faces on the powerful body 3 and on the rod 35, sandwiched between the power element 31 and the element 30, as a result of which transmitted to. the power element 31 to the groove 32 in the area with a weakened section. The groove 32 is selected so that when exposed to the power element 31 is destroyed, and the remaining parts (thread, flanges) of the actuating element 4 remained intact. As a result of the separation of part of the power element 31, i.e. the one on which the support plate 27 is fixed, from the rest, as a result of which the slopes 25 are released and under the action of the springs 7, the Z-shaped plates 24 will rotate, leaving the interface with the stop platforms 20 and 21 until they come out from the slots 18 and 19, and the grippers 5 and 6 are not completely released, which, taken to their original position, are completely released from the joint, the separable parts 1 and 2 of the vehicle.

For a new connection, it is necessary to install a new one instead of the destroyed power element 31, and the device can be reused.
