(54) РАБОЧЕЕ ОБОРУДОВАНИЕ ЭКСКАВАТОРА-ДРАГЛАЙНА(54) WORKING EQUIPMENT OF THE EXCAVATOR-DRAGLINE

1one

Изобретение относитс к рабочему оборудованию экскаваторов-драглайнов.The invention relates to the working equipment of dragline excavators.

Известно рабочее оборудование драглайна , включающее стрелу с головными блоками, лебедку, подъемные канаты и ковш, подвешенный на двух подъемных канатах, прикрепленных соответственно к его передней и задней части 1.Known working equipment of the dragline, including the boom with the head blocks, winch, hoisting ropes and a bucket suspended on two hoisting ropes attached respectively to its front and rear parts 1.

Недостатком указанного устройства вл етс сложность управлени ковшом при его движении по рабочей траектории изза необходимости регулировани длины трех канатов.The disadvantage of this device is the difficulty of controlling the bucket as it moves along the working path because of the need to adjust the length of the three ropes.

Наиболее близким к предлагаемому вл етс рабочее оборудование экскаваторадраглайна , содержаш.ее ковш с коромыслом , св занные с ковшом канатами т говую и подъемную лебедки и фиксируюш,ие канаты с лебедкой 2.Closest to the proposed is the working equipment of an excavatordragline, containing a ladle with a rocker, connected with a ladle with a rope and a lifting winch and fixing, and a rope with a winch 2.

Недостатками известного рабочего оборудовани вл етс ненадежность из-за наличи замкового устройства. При этом погрузка в автотранспорт мощными длинностреловыми экскаваторами-драглайнами не возможна, так как и в момент разгрузки ковша после открывани замкового устройства ковш удерживаетс только подъемными канатами и перемещаетс к положению , соответствующему максимальной величине радиуса разгрузки, что не позвол ет производить его фиксацию над транспорт ным средством.The disadvantages of the known working equipment are unreliability due to the presence of a locking device. In this case, loading into motor vehicles with powerful long-range dragline excavators is not possible, because even at the time of unloading the bucket after opening the locking device, the bucket is held only by the hoisting ropes and moves to the position corresponding to the maximum size of the unloading radius, which prevents its fixation over the transport means.

Цель изобретени - упрощение конструкции и повышение эффективности фиксации ковша.The purpose of the invention is to simplify the design and increase the efficiency of fixing the bucket.

Поставленна цель достигаетс тем, чтоThe goal is achieved by the fact that

10 в рабочем оборудовании экскаватора-драглайна , содержащем ковш, св занные с ним канатами т говую и подъемную лебедки и фиксирующие канаты с лебедкой, каждый фиксирующий канат св зан с концом коромысла .10, in the working equipment of a dragline excavator containing a bucket, associated traction and lifting winches with ropes, and fixing ropes with a winch, each fixing rope is connected to the end of the rocker arm.

Claims

Fixing ropes 1 of the working equipment of the dragline are connected at one end to the ends of the rocker arm 2 located between the lifting chains 3, and the second ends are fixed to the drums 4 of the winch 5 installed on the platform 6 of the dragline-excavator body 7. The drums 4 have spring-pneumatic type braking devices 8 and are located on a common shaft 9, which is driven by motor 10 through a gearbox 11. The engine 10 is powered by a thyristor converter 12 mounted inside the body 7. Trailer chains 14 are attached to move the bucket 13, from one side to the front of the side walls of the bucket 13, and from the other connected with the traction ropes 15. The lifting chains 3 are attached to the rear of the side walls of the bucket 13 and the second ends are suspended from the yoke 16 on the lifting ropes 17. A unloading rope 18, an envelope block 19 of the cage 16 and another end attached to the arch 20 of the bucket 13 are attached to the connecting chain of the 14 hauling chains and the hauling ropes 15. The bracing 15 and hoisting 17 ropes, the bending blocks 21, are fixed with the second ends respectively, at 22 and lifting 23 winches. These winches are installed inside the body 7, which is connected to the boom 24. Dragline, equipped with the proposed working equipment, works as follows. Ladle 13 is lowered to the bottom and includes a winch 22. Then, the ladle is moved and filled with rock. The motor 10 of the winch 5 permanently turned on through the gear 11 rotates the shaft 9, and the fixing ropes 1 are wound on the drum 4. After the rock has been collected, the loaded bucket 13 is transported to the place of unloading by means of the traction 22 and the lifting 23 winches. The movement of the loaded bucket 13 leads to the unwinding of the fixing ropes 1 from the drums 4, the shaft 9 begins to rotate in the opposite direction 5 11, passing through the gear 11 this direction of rotation to the engine 10, which creates tension on the fixing ropes 1, keeping them taut position To start the unloading of the bucket, it is sufficient to lock the reels 4 with the help of brake devices 8 and loosen the pull ropes 15. At the same time, the bucket 13 is held under the unloading position by the lifting 17 and fixing 1 ropes, which prevent it from moving forward. If necessary, the bucket can be unloaded at a fixed point or gradually in a uniform layer over a given area. To do this, it is necessary to manipulate the locking of the fixing ropes and the speed of the unwinding of the hauling ropes. The proposed working equipment of the dragline excavator simplifies the design and improves the efficiency of fixing the bucket over the vehicle. traction and lifting winches and fixing ropes with a winch, characterized in that, in order to simplify the construction and increase the efficiency of fixing the bucket, azhdy fixing rope is coupled to the end of the rocker.
