Изобретение относитс к подъемнотранспортному машиностроению и касаетс конструировани ловителей грузоподъемника .FIELD OF THE INVENTION The invention relates to lifting transport machinery and relates to the design of forklift lifters.

Наиболее близок к предлагаемому ловитель грузоподъемника, преимущественно крана-штабелера, содержащий смонтированную на грузоподъемнике подвеску, включающую огибаемый рабочим канатом блок с подвешенным к его оси коромыслом, и соединенные с ним шарнирно-рычажные приспособлени , имеющие клинь , расположенные в направл ющих грузоподъемника, а также пружинный механизм управлени работой клиньев, смонтированный в упорах И.Closest to the proposed forklift safety device, mainly a stacker crane, containing a suspension mounted on a forklift, including a block around the working cable with a beam suspended from its axis, and pivot-lever devices connected to it, having wedges located in the forklift rails, as well as spring mechanism for controlling the operation of wedges mounted in stops I.

Недостаток указанного ловител заключаетс в низкой надежности вработе и в невозможности обеспечени одновременного срабатывани клиньев ловител в случае обрыва рабочего каната грузоподъемника. The disadvantage of this catcher lies in the low reliability of the work and in the impossibility of ensuring that the catcher wedges operate simultaneously in the event of a break in the working cable of the forklift.

Цель изобретени - обеспечение одновременного срабатывани клиньев ловител в случае обрыва рабоче: каната грузоподъемника и повышение .надежности в работе.The purpose of the invention is to provide simultaneous actuation of the catcher's wedges in the event of a worker break: a forklift rope and an increase in reliability in operation.

Цель достигаетс тем, что пружины механизма управлени расположены по оси подвески, а шарнирно-рычажные приспособлени выполнены в виде двуплечих рычагов, один конец каждого из которых св зан с коромыслом , а другой - с клином ловител . The goal is achieved by the fact that the springs of the control mechanism are located along the axis of the suspension, and the hinge-lever devices are made in the form of two-arm levers, one end of each of which is connected with the rocker arm and the other with the wedge catcher.

На фиг. 1 изображен ловитель грузоподъемника , вид спереди; на фиг.2 вид А на фиг. 1.FIG. Figure 1 shows the forklift protector, front view; in FIG. 2, view A in FIG. one.

Ловитель грузоподъемника состо0 ит из коромысла 1, соединенного шарниром 2 через.стержень 3 с блоком 4, который огибаетс канатом 5. Коромыспо 1 упираетс в упоры 6 и соединено с шарнирно-рычажными приспособлени ми 7 и 8, а также с пружинами 9 и 10, расположенными по оси подвески . .The forklift safety device consists of a yoke 1, connected by a hinge 2 through a rod 3 with a block 4, which goes around by a rope 5. The yoke 1 rests on the stops 6 and is connected to the hinge-lever devices 7 and 8, as well as to the springs 9 and 10, located along the axis of the suspension. .

Пружина 9 св зана с нижним торцом коромысла 1, а пружина 10 - с верхним. Направление усилий обеих пружин направлено в сторону отжати коромысла 1 от упоров 6.The spring 9 is connected with the lower end of the rocker arm 1, and the spring 10 is connected with the upper end. The direction of the efforts of both springs is directed toward the release of the rocker arm 1 from the stops 6.

Каждое из приспособлений 7 или 8 содержит двуплечий рычаг 11, одним концом шарнирно соединенный с коромыслом 1, а другим - с клином 12.Each of the devices 7 or 8 contains a double-arm lever 11, one end of which is pivotally connected with the beam 1, and the other with the wedge 12.

Claims

The swing of the levers 11 is carried out around the hinges 13 fixed on the forklift. The wedge 12 has the ability to vertically move in the guides 14 with simultaneous horizontal movement due to the inclined guides 14 and the wide groove 15, which includes the rounded end 16 of the lever 11. The horizontal path of the wedges 12 is limited by the rigid guides 17. The load handler operates as follows in a way. In normal operation, without breaking the rope 5, the forklift is supported with its stops 6 on the yoke 1 which is held in position 6 pressed against the stops by the weight of the forklift. At the same time, the springs 9 and 10 are in a stressful state, and there is a small gap between the wedges 12 and the guides 17. When the rope 5 is broken, the rocker 1 stops pressing against the stops b and retracts downward by the forces of both springs 9 and 10. At the same time, the pivot-lever devices 7 and 8 are activated, the levers 11 of which are pivotally connected to the cors 1 1. The levers 11, turning around the hinges 13, they see a wedge 12 in the guides 14. At the same time, thanks to the freedom in the groove 15, the wedge can move in a horizontal plane and choose the gap between the wedge 12 and the guide 17. Due to the fact that both levers 1 are symmetrical relative to the suspension axis, then the stroke of the wedges 12 on both sides of the suspension is the same, i.e. With the same gaps between the wedges 12 and the guides 17, the wedges 12 act simultaneously. In the event of a failure of one of the springs 9 or K), the beam 1 is pressed by the second spring and the safety device operates normally. The arrangement of both springs along the axis of the suspension makes it possible to complete the whole mechanism with a structurally compact, conveniently fitting into the design of the forklift. Ensuring the simultaneous operation of wedges in the presence of two different types of springs and a simplified scheme of lever-hinged mechanisms, as compared with the known mechanisms, provide greater reliability of the entire device and its economic feasibility .. Invention formula Forklift truck, mainly a stacker crane, which is mounted on a load carrier the suspension, which includes a blocking rope with a working rope with a rocker suspended from its axis, and a pivot-lever device attached to it and having wedges located in the forklift guides, as well as a spring mechanism for controlling the work of the line, mounted in stops, characterized in that, in order to ensure the simultaneous operation of the catcher wedges in the event of a break in the working cable of the forklift and increase reliability in operation, the control mechanism springs are located along the axis of the suspension, and the hinge-lever devices are made in the form of double-arm levers, one end of which is connected with the rocker and the other with the wedge of the catcher.
