Изобретение относитс к грузоподъемному машиностроению и может быть использовано непосредственно в канатных подъемниках.The invention relates to lifting machinery and can be used directly in cable lifts.

Известно грузоподъемное устройство содержащее балку с перемещаюшейс по ней кареткой, несущей смонтированный на ори канатного блока фрикционный диск, привод каретки, выполненный в виде барабанов с охватывающим их тро cort, .жестко св занных с ведок лми шестерн ми, вход щими в зацепление с ведущей шестерней, выполненной за одно целое с фрикционным диском оси блока и установленной на втулке сколь жени , имеющей отверсти , рычаг управлени приводом с подпружикен-ным фиксатором , шарнирно-закрепленный на каретке l .A lifting device is known to contain a beam with a carriage moving along it, carrying a friction disk mounted on an oriental block, a carriage drive made in the form of drums with a drive cage associated with them and with gears engaging with pinion gears , made in one piece with the friction disk of the axis of the block and mounted on the sleeve sleeve, having openings, a drive control lever with a spring-loaded latch, hinged to the carriage l.

Однако в таком грузоподъемном уст ройстве рычаг с подпружиненным фиксатором , взаимодействующим с упором, смонтированным на балке, не обеспечивает надежности фиксации каретки в промежуточных положени х.However, in such a lifting device, a lever with a spring-loaded lock that interacts with a stop mounted on the beam does not ensure the reliability of fixing the carriage in intermediate positions.

Целью изобретени вл етс повышение надежности фиксации каретки.The aim of the invention is to increase the reliability of carriage fixation.

Это достигаетс тем, что рычаг снабжен двум рабочими упорами, один из которых выполнен с эвольвентным This is achieved by the fact that the lever is equipped with two working stops, one of which is made with an involute

зубом, в оси канатного блока выполнено отверстие, в которюм установлен ползун со штнфтом, вэаимодействуювшм с отверсти ми втулки скольжени , а рабочие упоЕ« рычага установлены с возможностью взаимодействи - один с ведущей шестерней, а другой - с ползуном .with a tooth, in the axis of the cable block there is a hole in which a slider with a pin is installed, it acts with holes of the sliding sleeve, and the working arms of the lever are installed with the possibility of interaction - one with the drive gear, and the other with the slider.

На фиг. 1 показана каретка с канатным блоком грузоподъемного устройства; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows a carriage with a rope block for a lifting device; in fig. 2 shows section A-A in FIG. one.

Устройство содержит балку 1 с перемещаемой по ней кареткой 2, снабженной роликами 3 и блоком 4 с канатом 5, один конец которого св зан с лебедкой, а другой сйаб ен грузопод емным органом.The device comprises a beam 1 with a carriage 2 being moved along it, equipped with rollers 3 and a block 4 with a rope 5, one end of which is connected to the winch and the other end is connected with a lifting body.

Привод баретки 2 выполнен в виде двух смонтированных на ней барабанов с тросом 7, охватывающим несколькими витками барабаны. Свободные концы троса закреплены посредством нат жньос устройств 8.The drive Bareka 2 made in the form of two mounted on her drums with cable 7, covering several turns drums. The free ends of the cable are secured by tensioning devices 8.

Claims

The drums 6 are rigidly connected with the gears 9 that engage with the pinion gear 10, which is made in one piece with the disk 11 and installed with it on the sleeve sleeve 12 through the bearing. The disk 1 can be tied to the willow in engagement of the intermediate friction disks 13 with a disk 14J fixed on the cable block 4. It is separate; The closed position of the friction discs 13 and 14 is provided. a spring 15, mounted on the axis 16 and a depressed sliding sleeve 12. For coupling the discs 11, 13; and 14 between them there is a drive control lever 17 pivotally mounted on the carriage and made with two blades, the elongated arm 18 of which is provided with a control cable 19 and the other The forked shoulder has two working lugs 20 and 21, wherein the working stop 20 interacts with the spherical end of the slider 22 mounted in the longitudinal hole of the axis 16, and the other working stop 21 engages with its involute gear 10 PSD Lake force of the spring 23. The slider 22 is formed with a transverse hole in which a pin 24, set at their ends in conductive sleeve sliding hole 12. The apparatus operates as follows. When lifting the load from the ground, the carriage 2 occupies one of the extreme positions in which the control lever is located with its working stop 21 with the involute tooth in engagement with the drive gear. The extended arm 18 of the lever 17 with the cable 19 is in the upper position, the friction discs 11, 13 and 14 are in the open position, and the rope arch 4 rotates freely on the axis 16. To move the carriage 2 along the beam 1, lower the lever 17 by means of a cable 19. In this case, the operating stop 21 of the forked lever arm disengages from the pinion gear 10, and the other operating stop 20 presses the spherical end of the slider 22, which closes the friction discs 13 and 14 through the pin 24, the sliding sleeve 12 and the bearing. As a result of the clutch of the disks through the pinion gear 10 and the driven gears 9, the drums b rotate, which, when the cable 7 is rewound, moves the carriage 2 along the beam 1 in one direction or the other. the axis of the rope block, a friction disk, a carriage drive, made in the form of drums with a cable surrounding them, rigidly connected with the driven gears which engage, with the lead wheel (with its gear wheel, made in one piece with a friction disk of the block axis and a slide having an aperture mounted on a sleeve; in the axis of the cable block there is a hole in which a slider is installed with a pin interacting with the openings of the sliding sleeve, and the working stops of the lever are installed with the possibility of interaction — one with the driving gear, and the other with a slider.
