Description
Изобретение Оиносито к грузоподъемным средствам, IB частности к гид|равл.ичеоким грейферам.The invention of Oinosito to lifting equipment, IB in particular, to guide | ravl.cheekim grabs.
Известные глдравлинеские грейферы содержат ipaiMy, .шарнирно соединен«|ую со ст;релой , Гидроцилиндр иривода челюстей, соединенных т гами с рамой, и лредодраиительное у|Ст,ройство.Well-known Gladravlin grabs contain ipaiMy, are hingedly connected to the station; Rela, Hydraulic cylinder of the jaw of the jaws connected by tubes to the frame, and frothurient y | St, roystvo.
Недостат1ком извест1НЫ|Х гидравлических грейферов вл етс то, что при возникновении предельных усилий возможны лоломки челюстей прейфера.The disadvantage of known | X hydraulic grabs is that when an extreme force occurs, chaffs of the preifer are possible.
Цаль изобретени - вредотвратать поломки челюстей грейфера три 1воз«ик«овении предельных усилий и обвс1пе|чить более интенсивное внедрение челюстей в материал.The trick of the invention is to damage the grapple's jaws for breakdowns three times the maximum force and surround the more intensive introduction of the jaws into the material.
Дл этого предохранительное устройство смонтировано в каждой челюсти и выполнено в виде подпружиненных втг/лак с фаской в одной стороне, вход щих в 0|боЙ1му, встроенную в т гу, соедин ющую челюсть с рамой, причем на стреле установлен г:иа1роц.или1Ндр поворота грейфера в вертикальной -плоскости, шарнирно соединено с рамой грейфера через рычажную систему.For this, a safety device is mounted in each jaw and made in the form of spring-loaded VTG / lacquer with a chamfer on one side, included in 0–1, integrated in the cable, connecting the jaw with the frame, and on the boom is installed: grab in the vertical plane, pivotally connected to the frame of the grab through the lever system.
На фиг. 1 изображен предлагаемый лрейфар , общий вид (щесть челюстей расположены по периметру окружности); на фиг. 2 - то же, вид сверху; на фиг. 3 - сечение поFIG. 1 shows the proposed leyfar, general view (the jaws are located around the perimeter of the circle); in fig. 2 - the same, top view; in fig. 3 - section along
А-А «а фиг. 1 (предохранительное устройство ).A-A “and FIG. 1 (safety device).
Грейфер состоит из /, сваренной из швеллеров, ,к которой по периметру оафужности прикреплены кронштейны 2; рычагов 3, закрепленных одним жонцам в кронштейнах 2, а другим - в челюст 1Х 4; подвижной Tipaверсы 5 с закрепленными на ней по периметру окружности челюст ми 4 и гидроцилиндра 6.The grab consists of / welded from channels, to which brackets 2 are attached along the perimeter of the power supply; levers 3, fixed to one tozhontsami in brackets 2, and the other - in the jaw 1X 4; movable Tipaversy 5 with jaws 4 and hydraulic cylinder 6 fixed on it along the perimeter of a circle.
Грейфер приводитсЯ в движение гидроцилиндром 7, расположенным на стреле 8 по-гр (у13чи1ка (крана) с помощью рычажной системы 9, и крепитс к стреле одним верхним 10 и двум нижними // шарнирами.The grab is set in motion by a hydraulic cylinder 7 located on the boom 8 in a horizontal mode (crane) using a lever system 9, and is attached to the boom with one upper 10 and two lower // joints.
Предохранительное устройство (фиг. 3) смонтировано в каждом кронштейне 2 и состоит из д(вух втулок 12 с фаской /5 на одной стороне и обоймы 14, копирующей форму втулок, на которую надеваетс рычаг 3. Втулки подпружинены пружиной 15. Регулируют усилие пружины гайками 16, установленными по торцу кронштейна 2.The safety device (Fig. 3) is mounted in each bracket 2 and consists of d (lugs of the sleeves 12 with a chamfer / 5 on one side and a clip 14 that copies the shape of the sleeves on which the lever 3 is worn. 16, mounted on the end of the bracket 2.
Грейфер работает следующим образом.The grapple works as follows.
Грейфер с помощью спрелы 8 направл етс на осмола (не гааказана) и при выдвижении щтока ги роцилин:дра 6 челюсти 4 раскрываютс . С раскрытыми челюст ми 4 грейфер опускаетс на кучу осмола, .при этом гидроцилиндром 7 производитс движеа-1иеThe grapple with the aid of the sprela 8 is guided to the osmol (not gasified) and upon the advancement of the gyrocyline sucker: the cores 6 of the jaw 4 open. With the jaws open 4, the grapple is lowered onto a pile of osmol, while the hydraulic cylinder 7 is driven.

This same hydrocillium 7 moves the grab to better embed it in the osmol when the grab is on a pile of osmol. After the grab is immersed in the osmol, the rod of the hydraulic cylinder 6 is retracted, and the jaws 4 are closed, i.e., the osmol is scooped. The boom 8 gets to a certain height and turns to the place of unloading. Grapple Handle. and ice, and the process repeats.
Предохранительное устройство работает следующим образом.The safety device operates as follows.
Если сжатие материала одной из пар челюстей превышает допустимое .и воэникает опасность поломки челюстей, давление от челюсти 4 пе:редаетс рычагу 3, а че|рез него на обойму 16, котора раздвигает втулки 12.Т1. стороны.

And there is a danger of jaw failure, the pressure from the jaw 4 ne: the lever 3 is passed, and through it the holder 16, which pushes the sleeves 12.T1. parties. The 3 roared together with the yoke 75 lifted the IB side of the pressure, thereby weakening the dangerous pressure of the I, appearing in the jaw 4, and preventing its breakage.

SU403622A1 (en) | DRIVE GRAYFER1 The invention relates to devices for gripping and lifting large sunken objects or submerged to a great depth. Objects are known as a gripping grapple containing a flooring frame, on which the jaws are articulated with two power cylinders. the capture of objects sunken or immersed to a greater depth. The purpose of the invention is to capture objects sunken or immersed to a greater depth. The above objective is achieved by the fact that the power cylinders are located above the They are connected by hinges with the jaws and are equipped with a common hollow rod, which communicates between the cavity of the power cylinders. In addition, in order to prevent the spontaneous opening of the jaws on one of them, the latch is made in the form of two bars rigidly connected between themselves and having curly cuts interacting with the corresponding finger of the hinge of the other jaw. To reduce the scooping efforts and prevent the formation of an earth cushion when gripping, the jaws are provided with soil-clearing nozzles connected to the water section of the collection-1015202530torae located in the body of each jaw. In order to transfer information about the jaw closure, the bar has latches in each jaw. figure cutouts are fitted with contact sensors for remote signaling. In FIG. Figure 1 shows the proposed grapple (In the closed CONDITION; in Fig. 2 — the same in the opened state;, in Fig. 3 • - the power drive in the section; in Fig. 4 - section A — A in Fig. 1. Drive The grab consists of frame 1, left 2 and right 3 crescent rotary jaws, two power pneumatic or hydraulic cylinders 4 \\ 5, and a common for both cylinders of rod 6. There is a nozzle 7 for supplying the working medium to cylinder 5 (FIG 3) has an internal through channel for the passage of the working medium into the second crank'Indr 4. The rotary jaws 5! 2 and 3 are hinged on the axes S and P of the frame / The upper ends of the jaws are hingedly connected to the power cylinders 4 and 5. On the fingers 10 of the hinges of the jaw 3, there is a folding catch 11, made in the form of two bars rigidly interconnected. The free ends of the bars have figured cuts interacting with the fingers 12 of the hinges of the jaw 2. Over fi- |
