Недостаток известного устройства ₁₅заключается в его низкой производительности.·A disadvantage of the known device ₁₅ is its low performance.

Целью изобретения является повышение производительности путем обеспечения ориентирования и фиксирова - го ния пучка для его захвата.The aim of the invention is to increase productivity by providing orientation and fixing of the beam for its capture.

Достигается это тем, что предложенный улавливатель снабжен вертикальными стойками, прикрепленными к ’ понтонам, и фиксирующим трапом, а захватный орган состоит из понтона, на котором шарнирно установлены зажимные и тяговые рычаги.This is achieved by the fact that the proposed catcher is equipped with vertical posts attached to the ’pontoons and a fixing ladder, and the gripping body consists of a pontoon on which clamping and traction levers are pivotally mounted.

На фиг. 1 показана общая схема работы устройства; на фиг. 2 - улавливатель и захватный орган, вид сверху; на фиг. 3 улавливатель, вид спереди; на фиг. 4 - зажимные и тяговые рычаги захватного органа; на фиг. 5 - захватный орган, вид сверху.In FIG. 1 shows a general diagram of the operation of the device; in FIG. 2 - catcher and gripping body, top view; in FIG. 3 catcher, front view; in FIG. 4 - clamping and traction levers of the gripping body; in FIG. 5 - gripping organ, top view.

Устройство для выгрузки пучков леса 1 из плота 2 содержит улавливатель 3, закрепленный тросами 4 на четырех якорях 5, и представляет собой П-образную конструкцию 6, плавающую над водой на расстоянии 0,5 м на четырех понтонах 7- К передней (по течению) части улавливателя 3 жестко прикреплены швеллеры 8, направленные вертикально вниз под воду на глубину до1 метра. Расстояние между швеллерами 8 равно 1,2 длины пучка леса. Проти948821 __ таскивается лебедкой 19 к крану 20, а захватный орган 16 холостым тросом 14 возвращается обратно. Зажимной рычаг 18 на шарнире 21 поворачивается холостым тросом горизонтально и также, как и'рычаги 17, утапливается в нишах и прорези в понтоне 16, не препятствуя движению всего,захватного органа.A device for unloading forest beams 1 from the raft 2 contains a catcher 3, fixed by ropes 4 on four anchors 5, and is a U-shaped structure 6 floating above the water at a distance of 0.5 m on four pontoons 7-K front (downstream) parts of the trap 3 are rigidly attached channels 8, directed vertically down under the water to a depth of 1 meter. The distance between the channels 8 is equal to 1.2 the length of the forest beam. Proti948821 __ is pulled by a winch 19 to the crane 20, and the gripping body 16 is returned by a single cable 14. The clamping lever 18 on the hinge 21 is rotated by the idle cable horizontally and, like the levers 17, is recessed in niches and slots in the pontoon 16, without interfering with the movement of the entire gripping organ.

По мере освобождения улавливателя 3 стержни, закрывающие вход в улавливатель, извлекаются и открывают вход в улавливатель очередному пучку. В дальнейшем устройство работает диалогично.As the catcher 3 is released, the rods that close the entrance to the catcher are removed and open the entrance to the catcher to the next bunch. In the future, the device operates dialogically.

Таким образом, предлагаемое устройство позволяет повысить произво- , дительность работы и обеспечить безопасность выполнения этих работ, так как рабочие не встают на пучки при их застройке, а захватный орган посредством дистанционного управления сам. захватывает пучки.Thus, the proposed device allows to increase productivity, productivity and ensure the safety of these works, since the workers do not stand on the beams during their construction, and the gripping body through remote control itself. captures beams.

Кроме того, улавливатель может быть сразу установлен в нужном месте на большой” воде, а для блока лебедки не требуется забивать сваи, так как блок крепится на конструкции улавливателя.In addition, the catcher can be immediately installed in the right place on large ”water, and for the winch block it is not necessary to drive piles, since the block is mounted on the catcher structure.

Claims

The invention relates to the timber and woodworking industry and can be used for mechanized unloading of timber bundles from water using a winch. A device for feeding forest beams to unloading mechanisms is known, comprising a catcher connected to an unloading platform, a beam including parallelly arranged pontoons with a gripping body located between them with a drive of displacement lj. A disadvantage of the known device is its poor performance. The aim of the invention is to increase productivity by aligning the liver and fixing the beam for its capture. This is achieved by the fact that the proposed catcher is equipped with vertical posts attached to the pontoons and a locking ladder, and the gripping organ consists of a pontoon on which the clamping arms and traction arms are hinged. FIG. 1 shows the general scheme of operation of the device; in fig. 2 - catcher and gripping body, type of super-, xy; in fig. 3 - front view catcher; in fig. - clamping and traction arms of the gripping organ; in fig. 5 - gripping body, top view. The device for unloading the beams of the forest 1 from the raft 2 contains a catcher 3 fixed by cables k on four corners x 5 and is a U-shaped structure 6 floating above water at a distance of m on four pontoons 7-K front (downstream) parts catcher 3 are rigidly attached channel 8, directed vertically down under water to a depth of 61 meters. The distance between the channels 8 is 1.2 times the length of the beam of wood. The opposite side 9 of the catcher 3 also contains channel bars 10, which are located 500-1000 mm apart. Between the parallel sides of the catcher 3 there is a locking ladder 11 with openings along the entire length. The diameter of the holes is 50-80 mm and they are made after 300 m. On the transverse wall 12 of the structure, a block 13 of a two-drum winch with an idle 14 and a load 15 cables is installed on a special area. The device also contains a gripping body in the form of a pontoon 16, on which two traction arms 17 and a clamping lever 18 are hinged. In addition, there is a two-drum winch 19 and a crane 20. The clamping lever 18 is suspended on the hinge 21. The device operates as follows. The raft fastened on the raid dissolves along ribbons into separate 1st bunches. Forest bundles 1 from raft 2 are melted by the flow of the river to catcher 3 fixed on four corners x 5 by means of cables k, and abutted on channels 8. with the help of the river flow, a beam of forest 1 is deployed along the river, and the beam enters the catcher 3 and swims up to channels-stops 10, which stop the beam of forest 1 by fixing them in order to avoid the beam turning by the river) with two fixing rods lowered into holes fixing ladder 11. Tr n 11 restricts entry in the extra beams catcher 3 by adding additional openings in its rods. The gripping body in the form of a pontoon 16 tons by stems 17 and clamping 18 levers is pulled by a single cable k through the guide rollers 19 to the fixed bundle t and pulled into the bundle. When the gripping device advances along the beam, the traction arms 17 are heated in the niche of the pontoon, and when the beam passes under the action of its own weight, the arms 17 return to their original position. Then, the cargo cable 15, which drives the clamping lever 18 through the guide roller 19, is pulled, and the beam 1 is clamped. The clamped beam, pulling down under 1, is pulled by the winch 19 to the crane 20, and the gripping body 16 is returned . The clamping lever 18 on the hinge 21 turns horizontally with the idle cable and, like the levers 17, sinks into the recesses and slots in the pontoon 16 without interfering with the movement of the gripping organ. As the catcher 3 is released, the rods closing the entrance to the catcher are removed and the entrance to the catcher is opened to the next bundle. In the future, the device works a tax. Thus, the proposed device allows to increase the productivity of work and to ensure the safety of these works, since the workers do not stand on the beams when they are locked up, and the gripping body captures the beams by remote control. In addition, the catcher can be immediately installed in the right place in the large water, and for the winch block it is not necessary to drive piles, since the block is mounted on the catcher's structure. The invention of the device for unloading beams containing a beam catcher connected to the unloading platform, comprising parallelly arranged pontoons with an interceptor gripping body with a drive for moving it, characterized in its grip, the catcher is equipped with vertical racks attached to the pontoons, and a locking ladder, and the gripping body consists of a pontoon, on which is articulated clamping and traction arms are installed.
