Description

Изобретение относится к транспортированию и разгрузке грузов, в частности, сыпучих грузов и может быть применено в любых отраслях народного хозяйства.The invention relates to the transportation and unloading of goods, in particular, bulk cargo and can be applied in any sectors of the economy.

Известен самоопрокидывающийся короб, в котором имеются верхние и нижние цап- 5 фы, установленные на боковых стенках причем нижние цапфы смещены относительно оси центра тяжести. На цапфах закреплена рама, которая цепями соединяется с краном [1]. ₁₀ A self-tilting box is known in which there are upper and lower trunnions 5 mounted on the side walls, and the lower trunnions are offset relative to the axis of gravity. A frame is attached to the pins, which is connected by chains to the crane [1]. ₁₀

В случае, когда необходимо опрокинуть короб, раму опускают и отводят в сторону. В результате этого верхние цапфы, расположенные по оси центра тяжести короба и придающие ему состояние равновесия, выходят из пазов рамы, и рама, поднимаясь, 15 опрокидывает короб.In the case when it is necessary to overturn the box, the frame is lowered and taken to the side. As a result of this, the upper trunnions located along the axis of the center of gravity of the box and giving it a state of equilibrium come out of the grooves of the frame, and the frame, rising, 15 overturns the box.

Недостатком такой конструкции является сложность ее и ненадежность в работе в силу того, что при расцеплении рамы с верхними цапфами короба на тележку подъ- ²⁰емного крана передаются наклонные усилия.The disadvantage of this design is its complexity and unreliability in operation due to the fact that when the frame is disengaged from the upper axles of the box, the inclined forces are transmitted to the trolley of the crane ²⁰ .

Цель изобретения — повышение надежности работы короба и упрощение его конструкции.The purpose of the invention is to increase the reliability of the box and simplify its design.

Эта цель достигается тем, что в верхней части боковых стенок короба установлены для цепей Г-образные скобы со скошенными в сторону цапф торцами, при этом основания скоб размещены в вертикальной плоскости, проходящей через центр тяжести короба, а в одной горизонтальной плоскости со скобами, на боковых стенках короба выполнены упоры для предотвращения проскальзывания цепей при опрокидывании короба.This goal is achieved by the fact that in the upper part of the side walls of the box, L-shaped brackets are installed for chains with beveled ends towards the axles, while the bases of the brackets are placed in a vertical plane passing through the center of gravity of the box, and in the same horizontal plane with brackets, on stops are made on the side walls of the box to prevent slipping of the chains when the box is tipped over.

На фиг. 1 изображен предлагаемый короб; на фиг. 2 — то же, вид сверху; на фиг. 3 — короб перед опрокидыванием; на фиг. 4 — короб в момент заведения цепей в Г-образные скобы для возвращения его в исходное положение.In FIG. 1 shows the proposed box; in FIG. 2 - the same, top view; in FIG. 3 - box before capsizing; in FIG. 4 - box at the time of establishment of the chains in the L-shaped staples to return it to its original position.

Короб содержит торцевые 1 и боковые 2 стенки, на которых установлены цапфы 3, Г-образные скобы 4 с основаниями 5 и скошенными в сторону цапф торцами 6.The box contains end 1 and side 2 walls, on which trunnions 3, L-shaped staples 4 with bases 5 and beveled ends 6 are chamfered to the side.

Напротив Г-образных скоб на боковых стенках короба выполнены упоры 7 для предотвращения проскальзывания цепей при опрокидывании короба. Короб соединяется с краном цепями 8.Opposite the L-shaped staples on the side walls of the box made stops 7 to prevent slipping of the chains when tipping the box. The box is connected to the crane by chains 8.

Короб работает следующим образом.Box works as follows.

При подъеме и транспортировке короба цепи 8, закрепленные на цапфах 3, проходят через Г-образные скобы 4, и так как основания 5 скоб проходят через оси центра тяжести короба, он находится в состоянии равновесия.When lifting and transporting the box chain 8, mounted on the pins 3, pass through the L-shaped staples 4, and since the base 5 of the brackets pass through the axis of the center of gravity of the box, it is in equilibrium.

Для опрокидывания короба цепи 8 опускаются и выводятся из оснований 5 скоб 4. Затем цепи поднимаются (фиг. 3), и короб опрокидывается.To tilt the box, chains 8 are lowered and removed from the bases 5 of the brackets 4. Then the chains are lifted (Fig. 3), and the box is tilted.

После опорожнения короб устанавливает ся торцевой стенкой 1 на опорную поверхность (фиг. 4), цепи 8 опускаются, скользя по скошенным торцам 6 скоб 4, опустившись ниже их, цепи 8 поднимаются до контакта с основаниями 5 скоб 4 и, продолжая подниматься, приводят короб в исходное положение.After emptying, the box is installed by the end wall 1 on the supporting surface (Fig. 4), the chains 8 are lowered, sliding along the beveled ends 6 of the brackets 4, dropping below them, the chains 8 are raised to contact the bases 5 of the brackets 4 and, continuing to rise, bring the box to the starting position.

Технико-экономический эффект от использования изобретения образуется за счет упрощения конструкции, уменьшения веса ее ориентировочно в 1 т на один короб. При стоимости 1 т оборудования 600 руб. экономия составляет 600 руб. на одном коробе. Повышается надежность в работе вследст вие ликвидации наклонных нагрузок на крановую тележку при работе с коробом.The technical and economic effect of the use of the invention is formed by simplifying the design, reducing its weight by approximately 1 ton per box. At a cost of 1 ton of equipment 600 rubles. saving is 600 rubles. on one box. Reliability in operation increases due to the elimination of inclined loads on the crane truck when working with the box.

(54) SELF-OVERVIDING BOXES The invention relates to the transportation and unloading of goods, in particular, bulk cargoes, and can be applied to any part of the national economy. A self-tilting box is known, in which there are upper and lower trunnions mounted on the side walls, the lower trunnions being offset relative to the axis of the center of gravity. A pin is attached to the pins, which is connected with a crane 1 by chains. In the case when it is necessary to tilt the box, the frame is lowered and retracted to the side. As a result of this, the upper pins, located along the centerline of the box body's weight and giving it an equilibrium state, emerge from the frame grooves, and the frame, when raised, tilts the duct. The disadvantage of this design is its complexity and unreliability in operation due to the fact that when the frame is disengaged from the upper trunnion trunnions, inclined forces are transmitted to the crane truck. The purpose of the invention is to increase the reliability of the box and simplify its design. : This goal is achieved by the fact that in the upper part of the side walls of the box, L-shaped brackets are installed with chains with trunnion faces, while the bases of the brackets are placed in a vertical plane passing through the center of the box body weight, and in one horizontal plane with brackets, on the side of the box walls are stops to prevent slipping of the chains when the box is tilted. FIG. 1 shows the proposed box; in fig. 2 - the same, top view; not figs. 3 - box before rollover; in fig. 4 - a box at the time of introduction of the chains into L-shaped brackets to return it to its original position. The box contains end 1 and side 2 walls, on which pins 3 are installed, L-shaped brackets 4 with bases 5 and butts beveled towards the trunnions 6. Opposite the L-shaped brackets on the side walls of the box there are stops 7 to prevent the chains from slipping during overturning box. The box is connected to the crane chains 8. The box works as follows. When lifting and transporting the chain box 8, mounted on the trunnions 3, passes through the L-shaped brackets 4, and since the base 5 of the brackets passes through the axes of the center weight of the box, it is in a state of equilibrium. In order to tilt the box, the chains 8 are lowered and pulled out of the bases 5 of the clips 4. Then the chains are raised (Fig. 3) and the box is tilted. After emptying, the duct is installed by the end wall 1 on the supporting surface (Fig. 4), chains 8 are lowered, slipping along the beveled ends of 6 brackets 4, dropping below them, chains 8 rise to contact with the bases of 5 brackets 4 and, continuing to rise, lead A box in the original polo Techno-economic effect from the use of the invention is formed by simplifying the design, reducing its weight approximately in 1 ton per box. At a cost of 1 ton of equipment, 600 rubles. saving is 600 rubles. on one box. Improves operational reliability due to the elimination of oblique loads on the crane truck when working with the box. Claims of the invention A self-tipping box containing trunnions mounted on the side walls of the box with an offset from the center of gravity axis and a chain for lifting the box, characterized in that, in order to increase reliability and simplify the design, in the upper part of the side walls of the box are installed for chains L-shaped brackets with butts obliquely in the direction of trunnions, while the bases of the brackets are placed in a vertical plane passing through the center of the frame of the frame of the duct, and in one horizontal plane with brackets, on the side st nkah duct formed abutments to prevent slippage of chains rollover box.
