(54) CRANE

Installed 1st cushion} The first stop is made with a slit, which includes the said wedge, which interacts with the stop, of another carriage.

FIG. 1 shows the proposed crane, a general view; in fig. 2 - the same, right view; in fig. 3 - crane boom, bottom view; in fig. 4 shows schematically trolleys of hoists and a chain with grippers; in fig. 5 - hoists and carts, top view,

Spores 3 with rollers 4, on which the boom 5 is mounted, are rigidly suspended to the gantry 1 of the portal through guides b mounted on the top of the 7 booms. A closed cargo truck is rigidly suspended to the lower boom on the SU 8. a monorail 9, on which non-propelled carts 10 hoists 11 are mounted.

 Parallel to the monorail 9, the beams 12 are rigidly suspended at the ends of the boom to the lower one by the su 8, each of the YESTERNS installed trolleys 13. At the bottom of the cross 8 ycia, sprockets 14, which are bent by the traction chain 15 with hooks, including the forward link 16 and rear 17 plates.

The sprockets 14 are connected to the gearbox 18, mounted on the bottom of the cross 8 arrows.

The clutch device of the non-self-propelled trolley 10 comprises a transversely mounted spring stop 19 and a longitudinally mounted spring 21 wedge 21 with a pull 2i and a roller 23, located on the same trolley 10 and a fixed stop 24 mounted on the other trolley 10.

, Each trolley 10 has a current collector 25 with tires 26.

The stop 19 is made with a cut, and which includes a wedge 2J,

On the self-propelled trolley 13, a moving stop 27 with a washer 28 is installed. The stop 27 is connected to the magnet core 29. A spring 30 is installed between the bay 28 and the wall of the trolley 13. On each trolley 13 there is an engine 31, a control cabin 32 and a current collector 33 with tires not shown). A flexible power cable is connected to each control cabin 32 (not shown in the figures) .:

The gantry 1 of the portal is equipped with a winch 34 with a cable 35. The konya rope is rigidly fixed to the ends of the boom 5. The portal is equipped with running: trolleys 36 mounted on the track 37. The anti-theft grippers 38 and gearboxes 39 with electric motors are mounted on each chassis 36. mi (not shown in the figures).

On the trolley 10 there is a hook 40 with a sloping side 41 and a slot b. The stop 19 is provided with a spring 42.

The crane will melt as follows.

Having finished the end of the boom 5 is placed above the trump of the unloaded vessel. To remove the boom 5 above the hold of the vessel, portal 2 is moved along the rails 37 and boom 5 along the rollers 4. Moving the boom 5 along the rollers 4 provides traction winch 34. One trolley is positioned above the hold, and the second is under the portal 2, where it is to unload the cargo from the ship's hold, after which the crane is ready to unload the cargo from the ship's hold. The gearbox drive 18 is activated, which is secured in the traction chain 15. The chain t is gripped parallel to the cargo monorail 9. The front grip plate 16, the passage above the stop 19 of the carriage 10, lowers the stop, and at the same time, the spring 42 is compressed. When the front grip plate 16 passes the stop 19, the spring 20 returns the stop

19in the starting position. The stop 19 is positioned between the plates 16, 17 of the grip,

and the chain 15 moves the carriage 10 along the monorail 9. When the car approaches the truck 10 to the carriage 13, the abutment 27 begins to move with the wedge 21 together with the wedge 21, which at the same time compresses the spring 20, together with this the abutment 27 slides along the slope side 41 of the hook 40 and moves, compressing the Spring 30. When moving the wedge 21, the stop 19 goes down, from the spring 42, and comes out of the hook 1B1 with the G6 plates,

17 capture. At the same time, the stop-27 enters the slot b of the hook 40 under the action of the spring 30. At the same time, the seals of the current collector 33 come into contact with the tires 26 of the current collector 25. The control switch turns on the engine and the hook falls into the hold of the vessel. Then a hook with a load is lifted, after which the motor of the hoist and magnet 29 are turned on, which draws in its heart with stop 27, spring spring 1 and 30. Stop 27 leaves the hook with 4JO and release 22, which together with the wedge 21 under the action of the spring

20 returns to its original position.

When the wedge 21 is moved to its original position, the stop 19 is released and returns

in its original position under the action of the instruments 42.

Prz TransitDan w of gripping over the stop 19 occurs with their catch and the trolley 10 with the load begins to move along the cargo monorail 9, and the tires 26 of the current collector 25 exit the conjugate communication with the tires of the current 33.

Claims (2)

A chain of 15 plates 16, 17 moves the hoist 11 with a load along the monorel, su 9 to the second trolley 13, which is located under the portal 2 and the gotora to engage with the cart 10 of the hoist And with the load in order to unload the load Portal 2 on the quay. In order to place the cargo over a certain place, use of the movement of carriages 13 (together with talts 11) along beam 12 (hoists 11, respectively, along the cargo monorail su 9), movement of the portal 2 itself along rails 37 and movement of the boom 5 along the rollers 4. When one of the hoists 11 approaches the hoist, which performs loading and unloading, i.e. is engaged with the carriage 13, the pin 23 of this waist rests on the support 24 in front of the standing waist 11. In this case, the pin 23 is moved by a wedge 21, which lowers. stop 19, and therefore, this stop of the hoist comes out of engagement with the plates 16, 17. After the hoist 11 comes out of the hook with the carriage 13, the wedge 21 of the next hoist returns to its original position, while the stop 19 also returns to its original position . The plates 16, 17 of the pick-up pick up this hoist and push it to the cart 13 for loading and unloading. . Thus, the hoists are constantly moved by the chain 15 in a single mono load. rail 9. From one carriage 13 to another carriage, hoists 13 move along one Golovin of a closed monorail 9, and back without cargo along the other half of a closed mono rail. The lifting and lowering of the load is controlled by two trolleys 13, one of which is located above the place from which the cargo is unloaded, and the second trolley 13 is located above the place where the load is loaded.
