Description

one

This invention relates to shipbuilding.

Bilge grinders are known that contain a frame that is movable on wheels, on which there are many fairgrounds with guard rails, a winch with a pull rope, a support bracket and a locking device.

The purpose of the invention is to expand the scope of work and increase convenience in exploitation.

For this, the frame is provided with a folding additional frame with working platforms and pins hinged to the support bracket, made in the form of a threaded rod with a sleeve. The locking device has a folding rail with teeth, which fall down behind the pins of the additional frame. In this case, the wheel supports are made telescopic.

FIG. 1 depicts the described fixing; in fig. 2 - locking device.

The layout consists of a frame 1, surrounded on three sides by working platforms 2 in several directions with a distance between the ruses above the average height of a person, and a working platform 3, the area of which allows to lower the clearance into the openings of ships. On the fourth side of the grouting, an additional grinder (frame) 4 is installed, which has a hinged fastening 5 at the ends of the sliding rods 6 moving inside the guide sleeves 7.

The winch 8, attached to the upper working platform 3, using a chain or cable drive 9 allows the frame to be tilted according to the angle of the bead

the vessel.

In order to prevent the frame 4 from falling if the chain or cable transmission of the winch 8 is broken, a frame locking device is used, which consists of folding rails 10 with teeth 11, one on each side of the frame that are pinned at one end on frame 1, and two protruding rods 12 on the frame 4. The supports of the wheels 13 are made, telescopic and consist of rods 14, terminated by turning wheels and set in cages 15 with the possibility of reciprocating motion. There are one in the cages, and several in the sterile x 14 are made of holes with a certain pitch a.

Locking pins 16 are provided to secure the rods 14, and locking devices 17 are provided to prevent them from falling out.

The device 17 consists of a guide rod 18 with a flange 19 in the middle, passing inside the guide bushings 20 with a spring 21 between the flange and the upper sleeve, which is pressed down so that it passes

lower end through the hole at the end of the stopper pin.

There is a hanging ladder 22 and two permanent ladders with wide steps 23 in tacking. All work sites are surrounded by rails 24.

A horizontal ladder 25, hinged 26 on frame 4 and having a roller on the second free end, which rolls along the working platform, serves to move from the platforms of one frame to another.

The frame 27 is provided for stitching the grind, and the winch 28 with the cable 29 is slid for moving the grind.

Bilge solving works as follows.

Using a portal crane, the lowering is lowered into the hold opening so that the wheels 13 touch the deck of the hold. Thereafter, the guide rods 18 are pushed up and out of the holes of the locking pins 16, which are removed. The ratcheting is raised or lowered to the desired height until the holes in the collars 15 and the rods 14 coincide, then the locking pins are inserted into the through holes, and the guide rods 18 are lowered so that the lower ends go to the iB hole at the ends of the pins 16.

If the rods 14 are extended, a ladder 22 is hung. The cable 29 is unwound in the direction of movement of the skidding fastened to the bulkhead or the holdboard. The winch with the help of mechanical or manual drive winds the cable, moving the grilling.

If the side of the hold, as well as the place of laying ell have a slope, the grating is rolled to the place of a slope, the sliding rod 6 is pushed forward, moving the frame 4 forward by the required amount. Thereafter, with the help of the winch 8, the frame 4 is inclined at the desired angle and secured.

Subject invention

A bilge hinge containing a frame that is movable on wheels, on which there are many brown platforms with guard rails, a winch with a traction cable, a support bracket and a locking device, differing from the fact that, in order to expand the scope of work and improve ease of operation, the frame is equipped a folding additional frame with working platforms and pins hingedly attached to the support bracket, the latter made in the form of a threaded rod with a sleeve, and the locking device is equipped with a folding rail with teeth that fall for the pins of the additional frame, and the wheel supports are made telescopic.
