Description

This invention relates to shipbuilding.

Known boat devices containing Gravitational davits, having a top arbor of a shovel with a boat winch mounted on the bed davits.

The purpose of the invention is to simplify installation and reduce Bes.

For this, the hoist winch is made with mutually perpendicularly mounted drums, one of which has a planetary gearbox, and the running end of the loops is fixed in the drum, whose axis is parallel to the axis of the turntable's rotation. another davit, missed through two mutually perpendicular sh. hooks mounted on the bed of this gateway.

FIG. A: 1 schematically depicts the proposed boat device, rear view; in fig. 2-VIEW .on the arrow A in FIG. one; in fig. 3 - view of the str “e B ia FIG. one; in fig. 4 - kinematic scheme of the winch.

The boat device consists of the right 1 and left 2 sloops, a lock winch 3 installed on the bed of the bed 4 with a left-side bench, guiding pulleys 5 and 6 mounted on the bed of the bed 7 of the left bed planter 2. Loops 8 and 9 are fastened on the bed cranks.

The dredger 1 is equipped with a manual drive 10, a drive brake actuator 11 associated with a winch remote control station (not shown in Fig.), And a blocking clamp 12 with a verb-hook 13.

The trailing end of the lopar 9 of the left pbalka 2 through the shchivy 5 and 6 passes on the drum 14,

which is located perpendicular to the axis of rotation of the davit 1 and fixed to it, and the running end of the blades 8 of the right davit 2 passes from the boom pulley (not shown) and the drum 15, parallel to the axis of the davitron 2, is fixed on it. The root ends of the lappers 8 and 9 are attached to the beds 4 and 7 of the slabs of the 1 and 2.

Winch 3 consists of an electric motor 16 connected by a centrifugal clutch 17 to a pinion gear shaft 18 of a planetary gearbox integrated into the drum 15. The planetary gearbox has a fixed epicyclic wheel 19 rigidly connected to the axis 20, a driven wheel 21 connected to the drum 15, rims

the satellites 22 and 23 are respectively engaged with the wheels 19 and 21.

The drove is made floating, its axial movements are limited by washers. The drum 14, connected with a drum 15 of a conical bunk 24, sits on bearings that rest 1 on an axle 20, rigidly connected to the casing 25 of the winch.

At the end of the shaft-gaterness 18, passing through the hole in the axis 20 and the planetary gearbox, a braking box is installed, consisting of a manual (tape) brake 26, a one-way overrunning clutch 27 and a centrifugal lowering brake 28.

The housing of the coupling 17 has an outer rim that can be connected to the gear 29 and, through a chain transmission 30, to the shaft of the manual drive E1.

The device works as follows.

Lifting and collapsing boats. From the electric motor 16, the rotation is transmitted through a centrifugal clutch, 17 to the gear shaft 18, which drives the rims of the satellites 22 and 23, transmitting torque through the wheel 21 to the drum, 16.

From the drum 15, through the conical pair 24, the rotation is transmitted to the -bar-bang 14. The gear ratio of the conical pair paiBHO I, therefore, the synchronism of the rotation of the drums is ensured. The lappers 8 and 9 are chosen at the same speed, and (the boat rises and collapses.

At the end of the charging, the electric motor is shut off, and the final filling is carried out manually. For this, the gear 29 is engaged with a crown on the coupling housing 17.

The removable handle of the hand drive 10 drives the shaft of the hand drive 31 through the chain drive of the drive, transmitting 30, 1 gear 29 and the outer crown of the clutch 17 through shaft gear 17 and further, through the planetary gear, to the reels 14 and 15.

After the return of the verb phrase 13 of the blocking cable 12 from the remote control station, the manual belt brake 26 is released by means of the parking brake actuator 11.

Under the action of the weight of the boat and davit, the reels 14 and G5 spin up, the gateway with the boat falls out, and then the boat is lowered, the lowering speed of which is limited by the centrifugal brake 28.

Subject invention

A boat device containing gravity davits having an upper

Wiring blades with a slot mounted on one of the davits (winch and pulleys, characterized in that, in order to simplify installation and reduce weight, the winch is sent with mutually perpendicularly mounted drums, one of which has a planetary gear, in the drum, the axis of which is parallel to the axis of rotation of the davit, the running end of the shovels of this davit is fixed, and on the other drum, the running end of the shovels of the other davit, passed through two mutually perpendicular shells Islands, mounted on the frame of the davits.
