Description

Изобретение относитс к грузоподъемному оборудованию и касаетс устройства дл .подъе на и кантовани грузов. The invention relates to lifting equipment and relates to a device for lifting and turning goods.

Известен захват .кантоваТель дл грузов,, например плоских строительных элементр:б, co-v держащий траверсу.-с.прицепной петлей и.ойоймы . с поворотно-уравнительным устройством (блоком), на которое запасован чалочный канат с крюками на концах. Дл автоматической фиксации груза в горизонтальном положении на каждом чалочном канате закреплена конусна колодка, запираема подпружиненной заделкой , установленной на обойме 1.Known gripper. Cant for goods, for example, flat construction elements: b, co-v holding the yoke. -S. Trailer loop and .oymoy. with a rotational-leveling device (block) for which a pulling rope with hooks at the ends is stored. To automatically fix the load in a horizontal position, a cone shoe is fixed on each pulling rope, locked with a spring-loaded embedment mounted on the yoke 1.

Однако известное устройство требует наличи специальной площадки дл кантовани груза В горизонтальное положение; кроме того, управление защелками довольно сложно в процессе эксплуатации.However, the known device requires a special platform for turning cargo into a horizontal position; In addition, the management of snaps quite difficult during operation.

Наиболее близким к предлагаемому изобретению по технической сущности и достигаемому результату вл етс захват-кантователь, содержащий навещиваемую на крюк грузоподъемного механизма траверсу, на концах которой установлены свободно вращающиес барабаны, на обечайках которых выполнены винтовые ручьи с запасованными в них стропами с крюками на свободных концах 2. The closest to the invention according to the technical essence and the achieved result is a tilting device containing a traverse, visited on the hook of the load-lifting mechanism, at the ends of which freely rotating drums are installed, on the shells of which screw streams are made with hooks stored in them with free hooks 2 .

Недостатком такого захвата-кантовател вл етс ненадежное удержание груза в горизонтальном положении при его транспортировании .The disadvantage of such a gripper is the unreliable holding of the load in a horizontal position during its transportation.

Целью изобретени вл етс повыщение надежности работы захвата-кантовател .The aim of the invention is to increase the reliability of the gripping-turning device.

Это достигаетс тем, что в предлагаемом захвате-кантователе обечайки каждого барабана имеют три рабочих участка, причем крайние выполнены с одинаковым диаметром, а средний имеет меньщий диаметр, при этом ручьи имеют переходные участки дл перевода стропа с одного рабочего участка барабана на другой.This is achieved by the fact that, in the proposed gripper, the shell of each drum has three working sections, the extreme ones having the same diameter, and the middle one having a smaller diameter, while the streams have transitional sections for transferring the sling from one working section of the drum to another.

На фиг. 1 изображен предлагаемый захват-кантователь , общий вид; на фиг. 2 - барабан; на фиг. 3 - то же, разрез по вертикальной оси.FIG. 1 shows the proposed tilting gripper, general view; in fig. 2 - drum; in fig. 3 - the same, a section along the vertical axis.

Claims

The gripper-turner contains the yoke 1, visited on the hook of the lifting mechanism for the loop 2. At the ends of the yoke installed freely rotating drums 3. The shell of each drum has three working sections 4-6. The diameters of the working sections 4 and 6 are equal to and larger than the diameter of section 5. On the sides of the drum there are screw threads 7 in which the lines 8 are stored with hooks at the free ends. The transfer of the sling from one working section to another is carried out at the transition section 9. The load 10, for example a panel, is delivered to the building platform on panel transporters in a position close to vertical. The hooks of the slings 8 cling to the lower and upper loops of the load 10. In this position, the slings 8 are always stored in the middle working area 5 of the reels 3. At the beginning of the lifting of the gripper-turner, the lower branches 11 of the ropes 8, which rotate the drum 3, first rotate the upper 3 the relaxed branch 12 of the rope 8 is wound on the working section 4 or 6 of the drum 3, the passage of the non-continuous section 9. The lifting of the load 10 will begin when the forces in the lower and upper branches of the ropes are approximately equalized. Simultaneously with lifting, the load is turned into a horizontal position in the direction of drawing out the upper branch 12 of the sling 8, which is wound on the section 4 or 6 of the drums and therefore has a greater torque than the lower branch 11. When the load is inclined to the horizontal position, the upper branch 12 of the sling 8 is unrolled from the section 4 or 6 of the drum, the transition to its parts 5. In the horizontal position of the load 10, both branches of the sling 8 are in the middle of the drum 3 and the torque moments in both branches of the sling 8 are balanced. At the same time, when unrolling the sling 8 from the section 4 or 6 of the drum 3, the free length of the branch 12 increases, which, accordingly, when the cargo 10 is tilted to the horizontal position, lowers its center of gravity. Thus, in the horizontal position of the load 10, it has the lowest position of the center of gravity and, therefore, the most stable position. The entire disruption of the horizontal load is connected with the necessity of winding any branch of the sling 8 on the sections 4 or 6 of the drum 3, which causes a considerable expenditure of energy on lifting the center of the weight of the load. 10. Formula of the invention: The gripper tiller containing the yoke At the ends of which there are free-rotating drums, on the shells of which screw-shaped streams are made with slings stored in them with hooks at the free ends, characterized in that, in order to increase the reliability and the work of the picker, the shells of each drum have three working sections, the extreme ones with the same diameter and the middle one having a smaller diameter, while the streams have transitional areas for transferring the sling from one working section of the drum to the other.
