Основным недостатком этого устройства является сложность конструкции. The main disadvantage of this device is the design complexity.
Известно также устройство для скалывания льда, содержащее раму с опорой и рукоятками, на которой смонтирован силовой привод, кинематически связанный с ударником, силовой привод включает двигатель внутреннего сгорания (ДВС), который посредством гибкого вала связан с генератором электрического тока, подаваемого на электромагнитный двигатель, на якоре которого закреплён ударник (ПМ N° 104565, КЛ Е01Н5/12) «Устройство для скалывания льда», RU,201 1г. A device for ice chipping is also known, comprising a frame with a support and handles, on which a power drive is mounted kinematically connected with a hammer, the power drive includes an internal combustion engine (ICE), which is connected via a flexible shaft to an electric current generator supplied to an electromagnetic motor, on the anchor of which a drummer is fixed (PM N ° 104565, КЛ Е01Н5 / 12) “Device for ice chipping”, RU, 201 1 g.
Недостатки этих устройств заключаются в том, что при удалении тонкого слоя льда применение ударной силы перпендикулярно к дорожному покрытию приводит к повреждению дорожного покрытия. The disadvantages of these devices are that when removing a thin layer of ice, the application of impact force perpendicular to the road surface leads to damage to the road surface.

Рабочий орган устройства соединён с источником силы. В качестве источника силы могут быть использованы отбойные молотки: электрический отбойный молоток, пневматический отбойный молоток, или отбойный молоток с ДВС, установленные на раме с опорой и рукоятками, долото которого соединено со штоком рабочего органа, а источник силы установлен на раме с опорой и рукоятками. The working body of the device is connected to a power source. As a source of force, jackhammers can be used: an electric jackhammer, a pneumatic jackhammer, or an ICE jackhammer mounted on a frame with a support and handles, the bit of which is connected to the working body rod, and the power source is mounted on the frame with a support and handles .
На фиг. 1 приведено устройство для скалывания льда, в котором в качестве источника силы используется отбойный молоток с ДВС. In FIG. 1 shows an ice chipping device in which an ICE jackhammer is used as a power source.
На фиг. 2 приведено устройство для скалывания льда, в котором в качестве источника силы используется электрический отбойный молоток. In FIG. Figure 2 shows an ice chipping device in which an electric jackhammer is used as a source of force.
На фиг. 3 приведено устройство для скалывания льда, в котором в качестве источника силы используется пневматический отбойный молоток.
Устройство содержит рабочий орган 1 , выполненный в виде пластины 2, режущая сторона 3 которой заострена. Пластина 2 жёстко соединена со штоком 4. Сверху рабочего органа 1 выполнены рёбра 5. Количество рёбер может быть от одного до четырёх. Ребра 5 расположены параллельно линии движения. Ребра могут иметь пилообразную форму или овальную форму. Режущая сторона рёбер заострена.

The cutting side of the ribs is pointed. Figure 1 shows the sawtooth shape of the ribs. As a source of power can be used ICE 6, an electric hammer 7 or a pneumatic hammer 8.
Работу устройства для скалывания льда, рассмотрим по фиг.1 , где в качестве источника силы используется ДВС; The operation of the device for chipping ice, we will consider in figure 1, where ICE is used as a source of force;
ДВС 6 установлен на раме 9 с опорой 10 и рукоятками 1 1. ДВС соединён со штоком 4 рабочего органа 1 с помощью кинематического звена (не показан). ICE 6 is mounted on a frame 9 with a support 10 and handles 1 1. ICE is connected to the rod 4 of the working body 1 using a kinematic link (not shown).
Оператор с помощью рукояток 11 придаёт раме 9 необходимый наклон при котором пластина 2 рабочего органа 1 соприкасается с поверхностью льда. Воздействуя на рычаги 12 управления, включается ДВС 6, который через кинематические звенья преобразует вращательное движение ДВС в возвратно-поступательное движение рабочего органа. Частота возвратно- поступательного движения рабочего органа от 15 до 50 движений в секунду и регулируется рычагами управления 12. В зависимости от состояния льда (хрупкий, вязкий), подбирается оптимальный режим работы рабочего органа 1. Рёбра 5, расположенные сверху рабочего органа 1 во время работы распиливают и скалывают лёд при пилообразном их выполнении, или раскалывают лёд на кусочки при овальной форме рёбер. Количество рёбер может быть от 1 при тонком и вязком слое льда и до 4 при толстом и хрупком слое льда. Ребра 5, расположенные сверху рабочего органа параллельно линии движения, снижают нагрузку на тротуарную плитку, предотвращая её повреждение. Микронеровности на тротуаре выбираются люфтом рабочего органа 1. По мере обработки поверхности, покрытой льдом, оператор з
перемещает устройство вперёд и визуально определяет условия манипулирования устройством. The operator using the handles 11 gives the frame 9 the necessary slope at which the plate 2 of the working body 1 is in contact with the surface of the ice. Acting on the control levers 12, the internal combustion engine 6 is turned on, which through kinematic links converts the rotational movement of the internal combustion engine into the reciprocating movement of the working body. The frequency of the reciprocating movement of the working body is from 15 to 50 movements per second and is regulated by the control levers 12. Depending on the state of ice (brittle, viscous), the optimal operating mode of the working body is selected 1. Ribs 5 located on top of the working body 1 during operation ice is cut and cleaved when sawtooth, or ice is broken into pieces with an oval shape of ribs. The number of edges can be from 1 for a thin and viscous layer of ice and up to 4 for a thick and brittle layer of ice. Ribs 5, located on top of the working body parallel to the line of movement, reduce the load on the paving slabs, preventing its damage. Microroughnesses on the sidewalk are selected by the play of the working body 1. As the surface is covered with ice, the operator z moves the device forward and visually determines the conditions for manipulating the device.
Работа устройства при использовании в качестве источника силы электрического или пневматического молотка аналогична работе приведённой выше. The operation of the device when using an electric or pneumatic hammer as a source of force is similar to the work above.

В устройстве для скалывания льда применена механизация, в качестве источника силы используется электрический молоток, питаемый от электрической сети, пневматический молоток, питаемый от компрессора, или отбойный молоток с ДВС. Благодаря этому скорость возвратно- поступательного перемещения рабочего органа достигает от 15 до 50 движений в секунду, что позволяет значительно повысить производительность труда оператора. Mechanization is used in the ice chipping device; an electric hammer powered by an electric network, a pneumatic hammer powered by a compressor, or a jackhammer with an internal combustion engine is used as a source of force. Due to this, the speed of the reciprocating movement of the working body reaches from 15 to 50 movements per second, which can significantly increase the operator's productivity.
Рёбра, расположенные сверху рабочего органа, распиливают или раскалывают лёд на мелкие куски, что позволяет обеспечить режим очистки ото льда поверхности. Ribs located on top of the working body, cut or split the ice into small pieces, which allows to ensure the regime of cleaning from ice surface.
Люфт 2-3 мм рабочего органа в вертикальной плоскости позволяет обойти микронеровности и исключить повреждения дорожного покрытия. Очищаемая поверхность при любом состоянии льда и снежного покрытия становится ровной, очищенной ото льда.
The backlash of 2-3 mm of the working body in a vertical plane allows you to bypass microroughness and eliminate damage to the road surface. The surface to be cleaned under any condition of ice and snow cover becomes smooth, free of ice.
