( УСТРОЙСТВО ДЛЯ ПОДОГРЕВА КАНАТА КАНАТНОЙ ПИЛЫ(DEVICE FOR HEATING ROPE OF ROTATING SAWS

, I ,.,:,. , I,.,:,.

Изобретение относитс к горной технике и вл етс необходимым при применении канатных пил.The invention relates to mining technology and is necessary when using wire saws.

Известны устройства дл подогрева канат канатной -пилы, содержащие источники, обеспечивающие нагрев каната, которые наход тс в укрыти х t1.There are known devices for heating cable-saws, containing sources that provide heating of the rope, which are located in the shelter t1.

Недостатком указанных устройств : вл1четс то, что необходимо обогревать укрыти , в которых наход тс устройства дл подогрева каната. |1 Наиболее близким к предлагаемому техническому решению вл етс устройство дл подогрерва каната канатной пилы, включающее нагревательные элементы и шкивы, один из которых расположен в корпусе, а два других установлены над ним и закреплены на поворотных вилках .The disadvantage of these devices is that it is necessary to heat the shelters in which the devices for heating the rope are located. | 1 Closest to the proposed technical solution is a device for preheating the rope of the wire saw, including heating elements and pulleys, one of which is located in the housing, and the other two are mounted above it and fixed to the swivel forks.

,Недостатком известного устройства вл етс его сложность.A disadvantage of the known device is its complexity.

Целью изобретени вл етс упрощение конструкции.The aim of the invention is to simplify the design.

Указанна цель достигаетс тем, что корпус заполнен частично водой и в нем расположены нагревательные элементы, при этом шкив, уст.ановленнь1Й в корпусе, полупогружен в воду.This goal is achieved by the fact that the casing is partially filled with water and the heating elements are located in it, while the pulley installed in the casing is semi-immersed in water.

На фиг. 1 изображена камнерезна установка, с устройством подогрева, общий вид; на фиг. 2 - устройство подогрева каната, разрез; на фиг.З разрез А-А на фиг.2.FIG. 1 shows a stone-cutting installation, with a heating device, general view; in fig. 2 - rope heating device, slit; on fig.Z section aa in figure 2.

Канатна пила включает приводную 1, нат жную 2, отводную 3 станций, рабочую стойку , погружную стойку S, устройство 6 дл подогрева каната , додатор 7 водоабрйзивной смеси и с водой.The wire saw includes a drive 1, a tension 2, a diversion 3 stations, a work stand, a submersible stand S, a device 6 for heating the rope, a dodator 7 of the water-jet mixture and with water.

Claims

The device for heating the rope comprises a housing E with thermal insulation 10, inside of which pulley 11 is placed on shaft 12, electric heater 13, Ti casing, brackets 15 and 16, swivel forks 17 and 18, guide pulleys 19 and 20. Shaft 12 is mounted on bearing bearings supports 21 and 22. 39 The device operates as follows. The rope enters the pulley 20 and is fed from it onto the pulley 11, which is partially submerged in water heated by electric motors 13. During its stay in the water, the rope heats up to positive temperatures. The heated rope then enters the pulley 19 and then on the immersion stand 5. As is known, heat transfer between a solid and a liquid is many times more intense than between a solid and a gas. Therefore, the rope has time to heat up during its stay in the water, but it will not have time to cool in the air before entering the cut. . . The use of a rope heating device allows year-round sawing of cables over the entire range of existing low ambient temperatures with energy costs that are substantially lower compared to the design of heating of sawmills, and the simpler design of the device regulated voltage sources. The invention of the device for heating the cable saw wire, including heating elements and pulleys, one of which is located in the housing and the other two are mounted above it and mounted on rotary forks, in order to simplify the design, the housing is partially filled with water and It is located heating elements, with the pulley installed in the housing, Polupruzhen in the water.
