Description

II

Изобретение относитс к грузоэаквагньгм усгройсгвам подъемных кранов и мо- жег быть использовано дл подъема штучных грузов и грузов в св зках.The invention relates to cargo e-usagrine cranes and can be used to lift piece goods and goods in connections.

Известна грузоподъемна траверса дл подъема и монтажа, содержаща секции , грузовой канат с зажимными прнспособлени ми , огибающий распределительные блоки, смонтированные на раме траверсы l .A well-known lifting beam for lifting and mounting, comprising sections, a cargo rope with clamping devices, enveloping distribution blocks, mounted on the frame of the crosspiece l.

Однако известна .траверса не аозво л ет использовать ее дл различных грузов как по весу, так и по габаритам.However, a traverse is not known to use it for various loads, both in weight and in size.

Это особенно ощутимо при работе в стесненных услови х на судах по монтажу переборок, насгилов и т.п., которые, имеют разные габариты и, следовательно, дл каждого вида обрабатываемого груза необходимо иметь отдельный комплект траверсы с распределительными блоками, устанавливаемыми каждый раз на различную высоту.This is especially noticeable when working in cramped conditions on ships for the installation of bulkheads, nasgilov, etc., which have different dimensions and, therefore, for each type of cargo to be processed, it is necessary to have a separate set of crossheads with distribution blocks that are installed on different times height.

Целью изобретени вл етс повышение эффективности работы траверсы.The aim of the invention is to increase the efficiency of the traverse.

Указанна цель достигаетс тем, что траверса снабжена установленными на раме регул торами нат жени , состо щими из парных реек с отверсти ми под заклацные пальцы, при этом свободные концы грузового каната зш реплены на регул торах нат жени .This goal is achieved by the fact that the traverse is equipped with tension regulators mounted on the frame, consisting of paired rails with holes for snap fingers, while the free ends of the load cable are replenished on the tension regulators.

На фиг. 1 изображена траверса, общий вид; на фиг. 2 - регул тор нат женн .FIG. 1 shows the traverse, general view; in fig. 2 - tension regulator.

Грузоподъемна траверса содержит раму 1, в нижней части которой с равным шагом установлены распределительные блоки 2.The lifting beam includes a frame 1, in the lower part of which distribution blocks 2 are installed with equal pitch.

Зажимные приспособлени 3, навешенные на грузовой канат 4, размещены меж ду блоками 2, .The clamping devices 3 hung on the cargo rope 4 are placed between blocks 2,.

Вверху на оконечност х рамы 1 установлены регул торы 5 нат жени с отверсти ми под закладные пальцы 6.Above, at the tip of frame 1, 5 tension regulators with holes for inset fingers 6 are installed.

Рама навешиваетс на стропы 7.The frame is attached to the slings 7.

Claims

The hanging sections of the rope 4, the flow rate, dc at an angle about, the lifting beam traverse works as follows. With conventional straps 7, frame 1 is attached to the hook of a lifting crane (not shown). The load rope 4 passes through distribution blocks 2 and clamping devices 3 installed between them, which are made with blocks (not shown) that interact with cable 4. Free ends of rope 4 are made with loops and secured in tension regulators 5 pins 6; For lifting (tilting) the planar sections, clamping devices 3 are mounted on their edges, after which the section is ready for lifting. When lifting, the clamping devices .3 transfer the load from the axes through their own blocks to the rope 4, cover and level the sections hanging from the distribution blocks 2 behind the moving interaction of these blocks with the rope. Since the strength of the load rope is influenced by the angle of divergence of its branches, for example, at maximum load, if its dimensions allow, the free ends of the rope are installed closer to the end of the frame. To do this, it is enough to remove the mortgage pin 6, move the end of the rope 4 to the selected hole on the tension controller 5 and fasten it here. At the same time, sections of the rope 4 are lengthened, the clamping devices are lowered, the rope is reduced, and the torque loads on the rope 4 are reduced. For the possibilities of lifting large-sized sections with a permissible weight, the ends of the rope 4 are rearranged and fixed at the openings of the tension adjuster at the ends of the frame. The invention allows to simplify the design of the crosspiece (there is no need to manufacture several hoists), to increase labor productivity when performing a wide range of cargo operations, and to increase the effectiveness of the operation of the crosshead. Invention Lifting yoke for lifting and mounting flat sections containing cargo rope with clamping devices, enveloping distribution blocks mounted on the yoke frame, characterized in that, in order to increase efficiency, it is equipped with tension regulators installed on the frame, From the pair of slats with holes for the inset fingers, the free ends of the rope load are attached to the tension adjusters.
