Description

Изобретение относитс к газоструйным машинам дл очистки покрытий от снега, льда и других загр знителей.This invention relates to gas jet machines for cleaning coatings from snow, ice and other contaminants.

Известна газоструйна машина дл очистки покрыти от льда и снега, содержаща самоходное шасси, смонти- рованный на Нем двухконтурный турбовентил торный двигатель, св занные с ним газопроводы с соплами, подключенными к соответствукадему кон.туру двигател и размещенными один внутри другого, причем внутреннее сопло закреплено шарнирно с возможностью поворота в вертикальной плоскости 13.A known gas jetting machine for cleaning ice and snow from ice, containing a self-propelled chassis, a double-circuit turbofan engine mounted on him, gas pipelines connected to it with nozzles connected to the engine profile and placed one inside the other, and the internal nozzle is fixed pivotally with the possibility of rotation in the vertical plane 13.

Однако конструкци известного устройства не позвол ет отключить или значительно ослабить воздействие одной из газовых струй при нормировании температурного пол общей газовой струи, что необходимо в тех случа х, когда удгшению подлежит снег либо лед.However, the design of the known device does not allow shutting down or significantly weakening the effect of one of the gas jets when normalizing the temperature field of the common gas jet, which is necessary in those cases when snow or ice is to be subjected.

Цель изобретени - расширение функциональных возможностей газоструйной машины.The purpose of the invention is to expand the functionality of the gas jet machine.

Указанна цель достигаетс тем, что она снабжена направл ющими щиткам , закрепленными на верхней и нижней част х внутреннего сопла, направлени газовых струй, а последнее выступает за пределы наружного сопла.This goal is achieved in that it is provided with guide plates attached to the upper and lower parts of the inner nozzle, the direction of the gas jets, and the latter protrudes beyond the outer nozzle.

Claims

15 two-circuit turbofan engine 2 and gas pipelines 3 and 4, located inside each other and connected respectively to the high-temperature internal 5 and low 20 temperature external 6 engine contours

2. The nozzle 7 of the internal gas pipeline 3 is made movable and fixed in its initial section on the axis 8 inside the nozzle 9 connected to the external gas pipeline 4. The output part of the nozzle 7 protrudes beyond the limits of the nozzle 9. The internal nozzle 7 is equipped with additional upper 10 and lower 11 walls, forming together with the shell 12 of the outer nozzle 9 a narrowing channel 13 of the outlet part of the outer nozzle 9. A mechanism 14 is provided for moving and locking in the working position of the nozzle 7. The machine operates as follows. When the machine moves along the cleaned coating, the multi-temperature gas flows flowing from the nozzle 7 and from the part of the channel 13 of the nozzle 9 not overlapped by the nozzle 7 form a two-layer jet, the lower layer of which affects the mass of the polluter, separates it from the top and together with the upper a layer of jet makes the contaminant outside the area to be cleaned. With an increase in the feed angle of the high temperature jet relative to the treated surface up to 30 °, the productivity of the machine in the process of drying the coating and removing ice increases. However, in order to remove snow from the coating, to avoid high-temperature ice covering the part of a two-layer jet, the coating should be removed from the coating at an angle of 5-10®, and the distance from the coating to the outlet of the high-temperature nozzle should be increased. Consequently, the range of the angle of inclination of the high-temperature nozzle should make up. 35-40. The low-temperature part of the two-layer jet should be directed to the coating during the ice-cleaning process at an angle of 10-20 °, and during snow-cleaning at an angle of 5-10 °. The proposed machine is more efficient than the prototype in cleaning from all types of precipitation, as well as removing dry snow and ice due to the increased length of the exit part of the inner nozzle and the presence of upper and lower additional walls of the inner nozzle. Claims of the Invention Gas jet machine for cleaning ice and cHeta from a coating, containing a self-propelled chassis, a dual-circuit turbofan-mounted engine mounted on it, UJ gas pipelines connected to it with nozzles connected to the corresponding engine contour and placed one inside the other, and an internal clip is clamped with a clamped clip clamped with an attachment clip. the ability to rotate in a vertical plane, characterized in that, in order to improve the functionality, it is equipped with directional shields attached to the upper and lower AST's inner nozzle and the latter extends beyond the outer nozzle.
