(54) ПРИВОД ГРУЗОВОЙ ТЕЛЕЖКИ КРАНА (54) TRUCK CRANE DRIVE

Изобретение относитс к подъемнотранспортному машинострюению, а именно к приводам грузовых тележек кранов.The invention relates to a lifting transport machine, namely, the drives of cranes trucks.

Известен привод грузовой тележки крана, содержащий двигатели, соединенные с основными тормозами и ведущими валами планетарного редуктора, ведомые валы которого соединены с бараба нами , и основные блоки, установленные на грузозахватной траверсе и охваченные гибкими органами, св занными с грузовой тележкой и барабанами 1.A crane truck drive is known, which contains engines connected to the main brakes and drive shafts of the planetary gearbox, the driven shafts of which are connected to the drum and the main blocks mounted on the lifting beam and covered by flexible bodies connected to the truck and drums 1.

Недостатками известного привода вл ютс сложность конструкции и от- сутствие средств, демпфирующих раска чивание груза.The disadvantages of the known drive are the complexity of the design and the lack of means of damping the breaking of the load.

Цель изобретени - уменьшение раскачивани груза.The purpose of the invention is to reduce rocking of the load.

Указанна цель достигаетс тем, что привод снабжен отклон ющими блоками , расположенными с одной стороны пути тележки, дополнительными блоками , установленными по углам тележки, и дополнительными тормозами, смонтированными на ходовой части тележки, причем барабаны установлены с другой стороны пути тележки, основные блоки расположены по углам упом нутой траверсы, а на каждом барабане закреплены одни концы по крайней мере , двух гибких органов, другие концы которых запасованы на дополнительные и основные блоки и закреплены на тележке, при этом гибкие органы одного из барабанов дополнительно запасованы на отклон кнцем блоке.This goal is achieved by the fact that the drive is equipped with deflection units located on one side of the trolley path, additional blocks installed at the corners of the trolley, and additional brakes mounted on the undercarriage of the trolley, the drums installed on the other side of the trolley path, the main blocks are located along the corners of the above-mentioned traverse, and on each drum one ends of at least two flexible organs are fixed, the other ends of which are stocked on additional and main blocks and fixed on the trolley, When this flexible bodies from one drum to further zapasovany kntsem deflection unit.

На фиг. 1 изображен привод грузо- вой тележки крана, общий вйд7 на FIG. 1 shows the crane truck drive, a common view of 7

10 фиг. 2 - кинематическа схема плане тарного редуктора, на фиг. 3 - ходова часть грузовой тележки.10 of FIG. 2 is a kinematic diagram of the plan of the gearbox; FIG. 3 - part of the cargo trolley.

Привод грузовой тележки 1 крана содержит двигатели 2 и 3, соединен15 ные с основными тормозами 4 и 5 и ведущими валами 6 и 7 планетарного редуктора 8, ведомые валы 9 и 10 которого соединены с барабанами 11 и 12, и основные блоки 13, установлен20 ные под углом грузозахватной траверсы 14. Отклон ющие блоки 15 расположены с одной стороны пути 16 тележки 1. Дополнительные блоки 17 установлены под углом тележки 1. Дополнитель The drive of the trolley 1 of the crane contains engines 2 and 3 connected to the main brakes 4 and 5 and the leading shafts 6 and 7 of the planetary gear 8, the driven shafts 9 and 10 of which are connected to the drums 11 and 12, and the main blocks 13 installed under the angle of load-gripping traverse 14. The deflecting blocks 15 are located on the same side of the track 16 of the trolley 1. The additional blocks 17 are installed at an angle of the trolley 1. Additional

25 ные. тормоза 18 смонтированы на ходовой части 19 тележки 1. Барабаны. 11 и 12 расположены с другой стороны пути 16 тележки 1. На каждом барабане 11 и 12 закреплены одни концы по 25 nos. the brakes 18 are mounted on the undercarriage 19 of the cart 1. The drums. 11 and 12 are located on the other side of the track 16 of the trolley 1. On each drum 11 and 12, one ends are fastened

Claims

At least two flexible organs 20 and 21, the other ends of which are connected to an additional 17 and 13 main blocks and mounted on trolley 1, while the flexible organs 21 of drum 12 are additionally connected to deflecting blocks 15. The crane trolley operates as follows. With the brake 4 turned on and the engine 2 turned on, the shaft 6 of the gearbox 8 rotates, and the driven shafts 9 and 10 of the gearbox 8 rotate synchronously in different directions, while the yoke 14 rises or lowers. When the brakes 5 and 18 are turned on and the shaft 7 is rotated by the motor 3, the driven shafts 9 and 10 rotate synchronously in one direction while the carriage 1 moves along the path 16. With the brakes 4.5 and 18 simultaneously turned on and the motors 2 and 3 simultaneously lifting the grass 14 and moving the cart 1. Due to the inclination of the flexible bodies 20 and 21 between the blocks 13 and 17, the oscillation of the crossbar 14 is limited. Claim of the Invention A crane truck drive containing engines connected to main brakes and driving shafts of a planetary gearbox, the driven shafts of which are connected to the drums, and the main blocks mounted on the lifting beam and covered by flexible bodies connected to the cargo cart and drums differing in that, in order to reduce rocking of the load, it is equipped with deflecting units, located on one side of the trolley’s path, with additional blocks installed at the corners of the trolley, and The brakes are mounted on the undercarriage of the trolley, the drums are installed on the other side of the trolley's path, the main blocks are located at the corners of the traverse, and on each drum one ends of at least two flexible organs are fixed, the other ends of which are reserved for additional and main blocks and secured on the bed, while the flexible organs of one of the drums are additionally stocked on the deflecting unit.
