Description

ИОГО разъединител буксировочной штанги описываемого устройства; на фиг. 3 - разрез но А-А на фиг. 2. Предложенное устройство содержит силоиомерительный элемент 1, на котором через параллелограммный механизм 2 закреплена буксировочна штанга 3 с аварийным разъединителем. К штанге 3 центром тйжести крепитс испытуема модель 4, Два рийный разъединитель содержит прилегающие один к другому верхний 5 и нижний б фланцьи Последние дел т штангу 3 на верхнюю и нижние части. Фланец 6 снабжен на торце упором 7, а фланец 5 - запорным бургом 8, обхватывающим сверху упор 7 фланца 6. Фланец 6 выполнен с торцовым экстент- риком 9, который зафиксирован запирающим зубом 10 короткого плеча 11 двуплечего Р1лчага стопорного механизма. Последний смонтирован на верхней части |..ггин1-и 3 и выполнен с шарнирно-откидным рычагом 12, фиксируемым в верхней части подпружиненным Стопором 13, масть рычага 12 посредством -т ги переменной длины шарнирно св зана с длинным плечом 14 двуплечего рычага стопорного механизм/ , .TsJra перкэменной: длины выполнена в вило цилиндра 15 со штоком 16, поршень 17 которого подпружинен. Фланец 6 выполнен с трапецеидальным в поперечном сечении выступом 18, а фланец 5 - со впадиной 19, обхвать1Ы1Юшей выступ 18 при сочленений 5 и б между собой. Описываемое устройство работает следующим образом. Фланцы 5 и 6 аварийного разъемника штанги 3 ввод тс в зацепление между собо Упор 7 помещаетс в бурт 8, а выступ 18 во впадину 19, Рычаг 12: переводитс в ра .:очее положение вращением вокруг шарнира прогни часовой стрелки. При повороте рычага 12 перемещаетс и шарнир, закрепленный на руко тке, который, в свою очередь, за- 45 сгаьл ет перемещатьс щток 16, При этом с/ шмаетс пружина, опирающа с одним тор цом иа верхнее донышко корпуса цилиндра 15, а другим - на поршень 17, Перемещение цилиндра 15 вызывает поворот против часо- ю вой стрелки двуплечего рычага, зуб 10 которого входит в контакт с эксцентриком 9 н фиксирует верхйий 5 и нижний 6 фланцы. При этом продолжаетс поворот рьичага 12 с дальнейшим сжатием пружины внутри цилиндра 15 до фиксации в рабочем положении стопором 13, При срабатьтвании аварийного разъединител стопор 13 при помошл привода, пово- 55ачива сь по часовой стрелке, освобождаетIOGO disconnector towing rod described device; in fig. 3 shows a section A-A in FIG. 2. The proposed device contains a force-measuring element 1, on which a towing bar 3 with an emergency disconnector is fixed via a parallelogram mechanism 2. The model 4 is attached to the rod 3 by the center of the test. The dual disconnector contains the upper 5 and the lower flanges adjacent to each other. The latter divides the rod 3 into upper and lower parts. The flange 6 is provided at the end with an abutment 7, and the flange 5 with a stop bolt 8, which engages the support 7 of the flange 6 from above. The flange 6 is made with an end extender 9, which is fixed by the locking tooth 10 of the short arm 11 of the two shoulders of the locking mechanism. The latter is mounted on the upper part of | .. ging-1 and 3 and is made with a hinged-folding lever 12 fixed in the upper part by a spring-loaded Stopper 13, the suit of the lever 12 by means of a variable length arm hinged to the long arm 14 of the two-armed lever lock mechanism / , .TsJra perkamennoy: the length is made for the cylinder 15 with the rod 16, the piston 17 of which is spring-loaded. The flange 6 is made with a protrusion in the cross section of the protrusion 18, and the flange 5 - with a hollow 19, obhvvat1YShe protrusion 18 with joints 5 and b between them. The described device operates as follows. The flanges 5 and 6 of the emergency diverter of the rod 3 are engaged in engagement between each other. The stop 7 is placed in the shoulder 8, and the protrusion 18 in the depression 19, the Lever 12: is translated into pa.: The outer position is rotated clockwise around the hinge. When the lever 12 is rotated, the hinge fixed on the handle moves as well, which, in turn, causes the rod 16 to move, while the spring supporting the end of the cylinder 15 with one end is on the piston 17. Moving the cylinder 15 causes a two-arm lever to turn against the clock hand, the tooth 10 of which comes in contact with the eccentric 9 n fixes the upper 5 and lower 6 flanges. At the same time, the rotation of the pictograph 12 continues with further compression of the spring inside the cylinder 15 until it is locked in the working position by the stopper 13. When the emergency disconnector is activated, the stopper 13 with the actuator turned, turning clockwise, releases

Claims

507480 55 SO lever 12, which, under the spring action inside the cylinder 15, makes an angular movement clockwise, turning the double-arm lever. The latter, due to the force of inertia and the force of the movement of the model, transmitted through the lower part of the rod 3, turns the Eccentric 9 out of engagement with the tooth 10 and eliminates mutual fixation of the flanges 5 and 6 of the emergency disconnector. The upper part of the boom 3, mixed together with the towing vehicle (not shown), goes forward, and the model 4 with the lower boom of the boom 3 stops under pressure from the propulsion force, leaving the formula afloat, hydrodynamic testing of high-speed models vessels, containing an emergency disconnector for a towing rod, one end of which is connected to the load cell and the other to a model of a high-speed vessel, which, in order to increase the reliability of emergency response about the dinitel connector of the towing rod, it is made in the form of two flanges adjacent to one another and dividing the towing rod to the upper and lower parts, while the lower flange is provided with a stop at the end, and the upper flange is provided with a locking shoulder holding the stop of the lower flange from above, the latter is made with an end eccentric, which is fixed by locking the tooth of the short arm of the two shoulders of the stopper mechanism, the latter being mounted on the upper part of the towing rod and made with a hinged-open lever spring-loaded stopper in the upper part, and the middle part of the hinged-hinged lever using a variable length, is hingedly connected with the long arm of the two-armed lever of the locking mechanism, 2, the device according to claim 1, differs from the fact that the variable ha The lengths are made in the form of a cylinder with a rod, then it is spring-loaded, 3. The device in paragraphs 1 and 2 is about the fact that the lower flange of the emergency disconnector of the towing rod is made with a trapezoidal cross section of the protrusion, and the top with a depression, wrapped around it vysgup npi junction of the upper and lower flanges.
