Description

Подача тока на портальные краны производитс  гибким кабелем, подключенным к штенсельным коробкам , или тролле ми, нрокладываемыми в каналах. Свободно подвешенные воздушные троллеи почти не употребл ютс , так как они могут быть легко повреждены стрелой крана или грузом. Питанне при помощи гибкого кабел  также недостаточно надежно, так как при передвижени х крана может быть вырвано штепсельное соединение или поврежден кабель.The supply of current to the gantry cranes is made by a flexible cable connected to the keyboard boxes or trolls laid in the channels. Freely suspended air trolls are almost never used, as they can be easily damaged by the boom of the crane or the load. The power supply with the help of a flexible cable is also not sufficiently reliable, because when moving the crane, the plug connection can be torn out or the cable can be damaged.

Указанные недостатки устран ютс  предлагаемым устройством, предпазначенным дл  питани  портального крана от штепсельных коробок , расположенных по трассе. Отличительной особенностью предлагаемого устройства  вл етс  размещение вводных предохранителей на контактпой тележке, что позвол ет избежать установки их в штепсельных коробках.These drawbacks are eliminated by the proposed device, preassigned to power the gantry crane from the plug boxes located along the route. A distinctive feature of the proposed device is the placement of the input fuses on the contact carriage, which makes it possible to avoid installing them in plug boxes.

На фнг. 1 п 2 приведен общий вид предлагаемого устройства в двух проекци х.On fng. 1 p 2 shows a general view of the proposed device in two projections.

Устройство состоит из токоподвод щего кабел  1, уложенного вдоль нодкрановых рельс, п контактов, расположенных в гнездах 2 с крьппками 3 и защитными изол ционными плитами 4. КонтактыThe device consists of a current-carrying cable 1, laid along the nodcrane rails, n contacts located in slots 2 with clamps 3 and protective insulating plates 4. Contacts

представл ют собой неподвижные ножи S, с которыми соедин ютс  контактные стойкн вилки 6, установленной на конце специального трубчатого рычага 7 портального крана. Устройство дл  питани  портального крана имеет также комплект предохранителей 8, расположенный па изол ционной панели.are fixed knives S, to which the contact pillars of the plug 6, mounted on the end of the special tubular lever 7 of the gantry crane, are connected. The device for powering the gantry crane also has a set of fuses 8 located on the insulating panel.

Последн   может свободно перемещатьс  по направл юш.им 9 на латках 10, что позвол ет портальному крану перемещатьс  вдоль подкрановых путей на 10 м, т. е. на рассто ние, равное рассто нию между гнездами 2.The latter can freely move in directions 9 and 9 on the patches 10, which allows the portal crane to move along the crane runways by 10 m, i.e., by a distance equal to the distance between the sockets 2.

Рассто ние между гнездами 2 беретс  нримерно равным базе портального крана, чтобы направл ющие 9 не выходили за габариты портала крана.The distance between the sockets 2 is taken to be approximately equal to the base of the portal crane so that the guides 9 do not extend beyond the dimensions of the portal crane.

Дл  небольших кранов (с базой 10 м) направл ющие 9 могут выходить за габариты крана; в этом случае необходимо предусмотреть защиту всего устройства от механических повреждений.For small cranes (with a base of 10 m), guides 9 may extend beyond the dimensions of the crane; in this case, it is necessary to protect the entire device from mechanical damage.

От предохранителей 8 через роликовые или скольз щие токоприемники 11 напр жение подаетс  на троллеи 12, расположенные в защитном коробе 13, а оттуда кабелем , проложенным по порталу крана , в кабину крано-вщика.From the fuses 8, through the roller or sliding current collectors 11, the voltage is applied to the trolleys 12 located in the protective box 13, and from there the cable running along the crane portal to the crane booth.
