Description

The utility model relates to military equipment, mainly armored vehicles, and can be used to uncouple an armored recovery and recovery vehicle (ARV) and an evacuated object without leaving the crew from the ARV in the event of an emergency in the conditions of warfare.

A known mechanism for the emergency uncoupling of a rutting mine trawl located on the upper frontal sheet of the machine body, comprising a body, a hook placed in the body, a hinge link, a hook grip interacting through the liner with a hook, a pyro charge and a pyrocharge charge piston located in the grip body interacting with the hinge link (see RF patent No. 2146799 dated 03/20/2000).

A disadvantage of the known emergency release mechanism is the large nomenclature and complexity of manufacturing the parts included in it.

The closest analogue (prototype) of the utility model is the emergency uncoupling mechanism (see patent No. 2527634 dated 09/10/2014), which contains a housing, cable, pyrocharge, piston, support hook for installing a tow rope, a support hook grab, and the hook grab is provided two handles to ensure its forced movement, while in the side walls of the housing made guide grooves for the passage of these handles.

The disadvantage of this prototype is the low reliability during operation, due to the fact that the piston that receives the energy of powder gases when the pyro-charge is triggered acts on the upper part of the support hook, which causes distortion in the vertical plane and deformation of the surface of the support. As a result, the gripper does not disengage from the support hook and does not release the tow rope. In addition, during prolonged use on the working surfaces of the support and grip, corrosion and oxide may occur, which can lead to jamming and malfunction of the device.

The utility model is aimed at improving the reliability of the emergency release mechanism when towing an evacuated object when the pyrolysis is triggered.

The essence of the utility model is that in the emergency release mechanism of the BREM containing the housing 1, cable 2, pyrocharge 3, piston 4, support hook 5, tow rope 6, grip 7, fixed support 8, spring 9, rotary axis 10, handle 11 , housing 12, an additional lubrication device is installed, which is installed by means of a thread in the spring cover 9, consisting of a housing 12 and a cap 13 connected to it by means of a thread 13. In addition, in this emergency uncoupling mechanism, the end surface of the gripper 7 of the support hook 5 is rounded, which ensures It freely moves in the horizontal plane under the influence of the piston 4 when the pyrocharge 3 is triggered.

The essence of the utility model is confirmed by the drawings, where in FIG. 1 shows an emergency release mechanism in a perspective view, FIG. 2 sectional side view.

The mechanism operates as follows during periodic maintenance, the lubrication of the working surfaces is carried out by screwing the cap 13 with grease through a threaded connection onto the housing 12, and the lubricant is extruded from the cap 13 onto the working surfaces of the fixed support 8 and the hook 7 is caught. During evacuation during operation pyrocharge 3 under the action of powder gases, the piston 4, moving, is in contact with the surface A of the capture 7 of the supporting hook 5, which is located in the fixed support 8 wool 7 of the supporting hook 5, and overcoming the force of the spring 9, moves it, thereby freeing the supporting hook 5. Moreover, the rounded end surface and the presence of lubricant provide free movement of the grip 7 of the supporting hook on the working surface of the fixed support 8. The supporting hook 5, driven in the movement of the weight of the tow rope 6, rotates about the axis 10 of the support hook 5, freeing the tow rope 6.

Thus, the introduction of an additional lubrication device into the mechanism and the rounded shape of the end surface of the gripper support hook will ensure its free movement in the horizontal plane relative to the support, which increases the reliability of this mechanism.
