This invention relates to lifting devices, in particular to shipboard freight elevators.

The purpose of the invention is to improve the reliability of the elevator when the vessel is rolling.

Fig. I shows a part of the elevator shaft with a cabin in Fig. 2 — section A-A on jeir.t (view of the door of the cabin in position and Closed); fig.Z - the same, in the Open position; Fig.4 is a section b-B in Fig.1.

In the shaft 1 on the rails 2 a cabin 3 of the elevators is installed. The cargo passage 4 of the shafts 1 is closed, for example, by a sliding door 5. Sliding door 6 is installed on the cables 3. Sliding doors 5 of the shafts have locking devices in the form of limit switches 7 included in the elevator winch electrical system. On the door 6 of the cab 3 A lock 8 is installed (Figures 2 and 3) fixed on one of the doors of the door 6 and consisting of a housing 9 with an axis 10. On it is a double-arm lever 11c hinged with a handle 12. The double-arm lever 11 is spring-loaded 13. A single end two shoulders of the lever 11 kinematically. connected with latch 14, and a friend th end - with m goy 15. The retainer 14 with the gap positioned in the housing hole 9 and protruding from the housing part included in the transparent hole. 16, which is fixed on the other leaf of the door 6. In the case 9, the element 17 is movably mounted, spring loaded 13.

On the guide 18 of the door 6, the bracket 19 is rigidly fixed, with which the rotatable plate 20 is rigidly articulated with the figure 21 that is rigidly fixed to it.

Near the top of its upper end, the bar 15 is pivotally connected to the slide 22, which is fixed to rotate on the axis 23, to the door leaf 6, and the stop cam 24 is rigidly fixed on the upper end of the rod 15. The sliding door 5 of the shaft is mounted on the guide 25 (Fig. 7) and is equipped with two layouts 26, vazimodeystvu | azimi with final vy.pn1 (chatter 7, installed on the wall of the elevator shaft.

The device works as follows.

When the cab 3 is stopped at the cargo opening 4-, the sliding door 5 of the shaft 1 opens manually. At this time, the slips 26 no longer affect the limit switches 7 and the elevator winch is blocked from starting. Then, the sliding door 6 of the cab 3 is opened manually. To do this, by applying a hand to the handle 12, rotate it and the double-arm lever 11 rigidly connected to it clockwise until it stops and push the doors 6 to the sides. At this, the lock 14 rises with the left shoulder of the lever 11 and The exit from the eyelet of the eyelet 16 is drawn into the housing 9, the spring 13 is extended, and the right lever arm 11, being lowered, moves the thru 15 with the cam-cam down. When sliding the doors of the door 6, the eyelet 16 comes out from under the latch 14, and the element 17, under the action of the spring 13, slides out of the housing 9 so that its left end is located under the latch 14. When the handle is stopped, the 12 two-armed lever 11 will remain fixed in a rotated clockwise position, and t he 15 with the stop-cam 24 locks in the lowered position.

When lowering the grip 15 with the cam-cam 24, the cam acts on the figure 21, so that the plates 20 rotate and move to a horizontal position all the way into the rail 25 of the door 5. Moreover, in the initial stage of rotation of the plate 20 the cam 24 turns , and in the final stage of rotation, when the stop-cam 24 comes out of contact with figured lay 21, under the action of its own weight.

In this manner, the pivot plate 20, when attempting to close the sliding door 5 of the shaft 1 of the door leaf, is pressed into the plate 20, the end of which is located on the guide 25 in its middle part. At the same time, the doors of the door 5 will not come to the Closed position, and the cuts 26 will not come into contact with the limit switches 7. The lift winch will remain blocked - its launch and movement of the cabin with the unlocked door are excluded.

In order to close the doors 6 of the cabin 3, it is necessary to manually fold the doors of the door, while the eyelet 16 pushes the element 17 into the body 9 of the lock 8, stretching the spring 13 until the latch 14 is in alignment with the hole in the eyelet 16 due to the rotation of the lever 11 around the axis 10 under the action of the spring 13.

When the doors of the door 6 move, the stop cam 24 with a clearance fits under the surface of the figure 21, and when the lever 11 is turned into the closed position of the lock, 8 tons ha 15 with the stand 24 rise up and the last, I act on the figure 21 of the rotary plate 20, puts it in a position close to vertical, i.e. to a position where between the pivot plate 20 and the fixed elements of the shaft a necessary clearance is formed along the entire trajectory of the cabin movement.

When turn the plate 20 under

This or not locked, provides increased reliability of the freight elevator when the vessel is rolling.

Claims (1)

Invention Formula An elevator, preferably a cargo ship, containing a shaft with cargo and openings and their doors, a cabin with a sliding door installed in the shaft and connected to a winch, all of which have a winch locking mechanism, in order to increase its reliability when the vessel is rolling, the cabin is equipped with an eye, and the lock mechanism of the cabin door winch includes a swivel plate. on the other hand, obstacles for closing the two- to two-pivotally mounted on the cab with There are no wells 5 of shaft 1 and it can be closed completely, while the cuts 26 on the doors of the door 5 will come into contact with the limit switches 7 and the elevator winch is unlocked. Winch can start and move the cabin.
