Description

1one

Изобретение относитс к подъемно-транспортной технике и может быть использовано , например, при погрузке деревьев.The invention relates to a lifting and transport equipment and can be used, for example, when loading trees.

Известно устройство дл погрузки длинномерных изделий, преимущественно деревьев, содержащее смонтированную на самоходном шасси полноповоротную раму, несущую шарнирно сочлененные между собой стрелу и руко ть , на конце которой установлен поворотный в вертикальной и горизонтальной плоскоет х гидравлический захват, и упоры, ограничивающие поворот захвата в вертикальной плоскости.A device for loading long products, mainly trees, is known, which comprises a full revolving frame mounted on a self-propelled chassis, carrying an arrow hingedly articulated between itself and a handle, at the end of which a hydraulic grip pivoting in a vertical and horizontal plane is installed, and the stops limiting the grip rotation in a vertical plane.

Однако в известном устройстве упоры обеспечивают горизонтальное положение деревьев только на одной определенной высоте разгрузки груза, тогда как погрузочные операции в больщинстве случа х требуетс выполн ть на различных высотах, например при щтабелевке сортиментов она измен етс в пределах высоты щтабел , поэтому при укладке деревьев на промежуточных вьюотах из-за провисани концов захваченных деревьев затрачиваетс врем на дополнительный подъем груза. Это приводит к увеличению рабочего цикла, снижает производительность устройства.However, in the known device, the stops ensure the trees to be horizontal only at one certain height of unloading the cargo, while loading operations in most cases are required to be performed at different heights, for example, when dividing logs it varies within the height of the shtatel, therefore when laying trees on intermediate The viewpoints, due to the sagging of the ends of the captured trees, take time to increase the load. This leads to an increase in the operating cycle, reduces the performance of the device.

Цель изобретени - обеспечение разгрузки деревьев на различных высотах и ускорение процесса погрузки их.The purpose of the invention is to provide unloading of trees at different heights and speeding up the process of loading them.

Дл этого руко ть снабжена, П-образным рычагом, несушим подвижные упоры, и гидравлическим цилиндром, при этом щток последнего соединен с П-образным рычагом, на свободных концах которого шарнирно установлены подвижные упоры, взаимодействующие с упорами, ограничивающими поворот захвата.To do this, the handle is equipped with a U-shaped lever, a non-drying movable stops, and a hydraulic cylinder, the latter being connected to a U-shaped lever, at its free ends, movable stops that interact with the stops that limit the rotation of the grip.

Claims

The described device for loading long items comprises a full revolving frame 1 mounted on a self-propelled chassis and: rotating on a turntable

2. On the rotary frame, working equipment was visited, including boom 3, arm 4 coupled to it, carrying hydraulic grip 5. Working equipment is controlled by hydraulic volumetric drives: hydraulic cylinders of boom, arm, jaws clamp and torque. The rotation of the maxillary gripper in the horizontal plane. The movable stops 10 and 11 are connected with the U-different lever 12, have the ability to rotate on the axes 13 and 14 the crosshead 15 by means of a strong hydraulic rod 16 and interact The traverse position indicator consists of a scale 19 fixed on the handles and an arrow 20s rigidly connected to the stop. The device is operated in the following sequence. Pre-determined height, at which unloading must be done5, using the position indicator, set the stops 1O and 11 using the hydraulic cylinder 16 to the desired position of the Tapee by turning the swiveling raksa and manipulating with the boom and the arm, the grip is brought to the log, positioning it so that the center of gravity is displaced towards the grip comb by about a barrel, and the wood is clamped using the hydraulic cylinder 8. Manipula with boom and arm; U-turn frame and jaw grip stack tree in the desired location. Due to the use of movable stops controlled by a power cylinder, it becomes possible, depending on the required conditions for the production of loading and unloading operations, to periodically change the position of the stops and obtain the optimum time of the working cycle. Apparatus of the Invention A device for loading long items, mainly trees, comprising a full revolving frame mounted on a self-propelled motor vehicle carrying a boom and a hinge jointly attached to each other, at the end of which a hydraulic gripper pivoting in horizontal and vertical planes and limiting the gripper turning is mounted In a vertical plane, characterized in that, in order to ensure the unloading of trees at different heights and speed up the process of their loading, the handle is provided with a U-shaped p chagom carrying movable stops, and the hydraulic cylinder, wherein the latter is connected to schtok n- shaped lever, on the free ends of which scharnirno uotanovleny movable stops cooperating with stops limiting the rotation of grip.
