Description

Изобретение относитс к судостроению , а более конкретно к механизации стапельных работ при стыковке балок судового набора-.The invention relates to shipbuilding, and more specifically to the mechanization of the berth during the docking of shipboard beams.

Известна скоба дл стыковки балок судового набора, содержаща корпус с двум захватньми губками и прижиMOMp-J .A known bracket for joining shipboard beams, comprising a hull with two gripping jaws and MOMp-J prizi.

Недостатком известной скобы. вл етс больша трудоемкость при устат новке ее и сн тии, так как рабочему необходимо одной рукой держать скобу и одновременно манипулировать с прижимом , выполненным в виде рычага и эксцентрика.The disadvantage of the known bracket. is a great deal of effort in installing and removing it, since the worker needs to hold the clamp with one hand and at the same time manipulate the clamp made in the form of a lever and an eccentric.

Известный прижим требует достаточно больших усилий со стороны рабочего дл фиксации балки при повороте рычага.Кроме того, известна конструкци не позвол ет обеспечить высокую точность стыковки балок судового набора.The known clamping requires quite a large amount of effort from the side of the worker for fixing the beam when the lever is rotated. Moreover, the known construction does not ensure high accuracy of the joining of the shipboard beams.

Цель изобретени - повьпыение производительности стыковки и ее точности . The purpose of the invention is to vary the performance of the dock and its accuracy.

Указанна цель достигаетс тем, что скоба дл стыковки бгшок судового набора, содержаща корпус с двум захватными губками и прижимом, снабжена шарнирно закрепленным наThis goal is achieved by the fact that the bracket for docking the shipboard bgshack, comprising a housing with two gripping jaws and a clamp, is hinged on

корпусе фиксатором дл взаимодействи с балкой и нажимной подпружиненной планкой,один.конец которой также шарнирно закреплен на корпусе, а другой конец - на фиксаторе, при этом захватные губки смонтированы на корпусе по разные стороны относительно продольной его оси со смещением одна от другой вдоль оси.the housing with a latch for engagement with the beam and a pressure spring-loaded bar, one end of which is also hinged on the body and the other end on the latch, while the gripping jaws are mounted on the body on opposite sides relative to its longitudinal axis offset from one another along the axis.

Скоба содержит корпус 1 с жестко закрепленными на его противоположных боковых сторонах захватными губками 2 с выступами а, обращенными друг к другу. Захватные губки 2 рас20 положены вдоль корпуса так, что рас сто ние между об1#ащенными друг к внутренними углами Ь выступов а превышает ширину с головки балки. На корпусе 1 шарнирно закреплен фикса25 тор 3, выполненный в виде собачки с запирающим выступом d , имеющим заходной скос и взаимодействующим со стороны головки балки.The bracket includes a housing 1 with rigidly attached to its opposite sides of the gripping jaws 2 with the projections a facing each other. The gripping jaws 2 are arranged along the body in such a way that the distance between the internal angles b of each projection to each of the angles b of the protrusions exceeds the width of the beam head. A fixer 3 is hinged on the housing 1; it is made in the form of a pawl with a locking projection d, which has a lead-in bevel and interacts with the beam head.

Claims

At the end of the retainer 3, opposite the doggie, is pivotally fixed with one of its ends, the pressure bar 4 is made T-shaped. At the same time, the other end of the pressure plate 4 is also hinged to the bracket body. Plank 4 around the body. A pressure limiter position is installed on the housing. A vertical hole is made in the housing, in which a compression spring 5 is placed, which all the time presses the pressure bar 4 up to the limit of the position limiter in the housing, while the lock 3 takes a horizontal position. The head of the housing is equipped with a clamp, made in the form of hydraulic cylinders. Bracket set as follows. With one hand, take the upper part of the housing 1, point the beam at the beam at an angle so that the head of the beam passes between the angles L facing to each other of the projections and the gripping jaws

2. After the protrusions a will be the head of the beam, the bracket is turned to a position along the beam. In this case, due to the bevel of the locking protrusion d, the retainer rises first when rotating, and then fixes the bracket for the edge of the head of the ball. After this, 1 hydraulic cylinder b is installed in the hull head and the beams are aligned. To remove the bracket from the beam, it is necessary to remove the hydraulic cylinder b, take it from the upper part of the housing 1 and at the same time pressing the pressure bar 4. At the same time, the protrusion d of the pawl unlocks the bracket. Remove the bracket from the beam in reverse order. The invention increases productivity by 10%, since the installation, release and removal operations from the beam can be performed with one hand without any additional effort for fixing. Increased productivity is also achieved by reducing the time for fixation and unbracing the clip, as this is done automatically. In addition, the proposed bracket allows to improve the accuracy of joining shipboard beams. Claims for joining shipboard girder brackets, comprising a body with two gripping jaws and a clamp, in order to increase the docking performance and its accuracy, the bracket is provided with a latch hinged on the body for interaction with the beam and a pressure spring-loaded bar, one end of which is also hinged to the body, and the other end to the retainer, with the gripping jaws mounted on the body on opposite sides relative to its longitudinal axis offset from one another lengthwise axis.
