However, these devices are not intended for the automated lubrication of brake cables used on water vehicles.

In particular, during flights of carrier-based aircraft on the aircraft-carrying cruiser "Admiral of the Fleet of the Soviet Union Kuznetsov", in accordance with the regulations, the brake cables of the aircraft carrier are lubricated. Currently, maintenance of the torsos is done manually by military personnel using rubber gloves and a bucket of grease. Violation of the regulations for servicing the brake cables of the aircraft finisher in a number of cases leads to their breakage during aircraft landing and tragic consequences.

This method of lubricating and maintaining the cables is not perfect and has significant disadvantages :

1. Lubrication is insufficient and uneven.

2. Control of the integrity of the brake cables is not objective and is associated with a human factor.

3. The exact consumption of grease for one rope at one pass is unknown due to the uneven application of grease to the rope.

4. In conditions of subzero temperatures and ice build-up on the cables, high-quality manual lubrication is impossible.

5. Before using the automatic cable lubrication mechanism.

6. There is no objective control of the condition of the cables.

The technical problem of the claimed invention is to create a mechanism for automated lubrication of brake cables (MASTT) on military and civil ships.

The technical result consists in the implementation of the purpose.

The specified technical result is achieved in the mechanism of automated lubrication of brake cables, containing a housing consisting of two parts tightly adjacent to each other, inside which are made: bumpers-limit switches and brushes-cuffs located on both sides of the specified housing, a device for non-destructive testing of the cable containing gap sensors that scan the integrity of the brake cable and, through a communication module, transmit the scanning parameters to the operator's control panel, a lubricant reservoir, inside which heating elements are made, metering bushings (5) that supply lubricant by drip to the cable and located on both sides of the reservoir with lubrication, drive roller and pressure rollers with a spring mechanism, a control unit that transmits control signals received from the operator's control panel to turn on / off the electric motor with a gearbox driving the drive roller, battery.

An additional feature is that it has a substantially cylindrical shape with a flat bottom and curved tapered ends.

An additional feature is that the wall of the reservoir with the lubricant is filled with Penoplex to ensure that the lubricant maintains a constant temperature.

The device is also explained using drawings, where:

FIG. 1 - MASTT scheme (side view);

FIG. 2 - MASTT diagram (sectional view);

FIG. 3 is a diagram of a part of the MASTT body.

The automatic brake cable lubrication mechanism has a substantially cylindrical shape with a flat bottom and curved tapered ends. Its length is 700 millimeters and width is 280 millimeters. Consists of two tight-fitting parts and is divided longitudinally.

At the entrance and exit, on both sides of the MASTT body, there are bumpers-limit switches (1) providing the start of movement and a change in direction when the end of the cable and the brush-cuff (2) is reached, then there is a device for non-destructive testing of the cable (3), containing gap sensors that scan the integrity of the brake cable and, through a communication module, for example Wi-Fi (not shown), transmit the scanning parameters to an operator control panel, for example, a laptop (not shown).

On both sides of the reservoir with grease (4) there are metering bushings (5) that supply grease by dripping onto the cable. The guarantee of uninterrupted lubrication of the brake cable is provided by the pressure circuit and metering sleeves, the height of which determines the thickness of the lubricant. The dosage of applying the lubricant depends on the presettings of the metering sleeves, by reducing (increasing) the gap between the cable and the sleeve, as well as the number and shape, size of the metering nozzles.

Heating elements (13) are made inside the reservoir, which serve to heat the lubricant and ensure its application to the cable during the movement of the mechanism. The reservoir is filled with grease by means of a pneumatic syringe through the grease filling connection (14). The wall of the reservoir with the grease is filled with Penoplex to ensure that the grease maintains a constant temperature.

The movement of the brake cable inside the MASTT body (12) is provided by the drive roller (8) and pressure rollers (7) with a spring mechanism (15), as well as due to the tight fit of the cuff brushes (2) and the translational movement of the mechanism. In this case, the driving roller is driven by an electric motor (10) with a gearbox (9), the power to the electric motor is supplied from a storage battery (6).

The device is controlled and the condition (integrity) of the cable is monitored remotely by the operator from the ship's control post for the aircraft carrier's braking system on the operator's control panel. Control signals from the operator's control panel via Wi-Fi are transmitted to the MASTT control unit (not shown) generating a control signal to an electronic key (for example, a transistor), which supplies (turns off) power to the electric motor driving the device.

The device works as follows.

The mechanism begins to move and changes direction when it reaches the end of the cable using bump switches (1), which are located on both sides of the MASTT body. One of them changes the direction of movement, and the other turns off the mechanism. When MASTT moves, the cable passes through a non-destructive testing device, metering bushings, a reservoir with lubricant, and carries with it the required amount of lubricant due to twisting of the cable threads and further, through metering sleeves, pressure and drive rollers, cuff brushes, bump stop switch and exits the MASTT building. Making a forward motion along the brake cable, MASTT passes twice its entire length, applies the required amount of lubricant through drip dispensers, and also monitors the integrity of the cable.
