The device contains a contactless drum 1 with a cable 2 mounted on a bridge crane trolley for supplying the traction motors of the machine from an external power source. The device is equipped with a controller that consists of a body, the upper flange of which has four figured cutouts, and the bottom is bored out under a spherical support, through which a pipe is passed with a power cable with a bearing attached to it and an annular magnet that interacts with magnetically controlled sensors opposite the figured cutouts . At the same time, one pair of diametrically located magnetic sensors is included in the circuit of time relay coils, the contacts of which, with time release, switch the starting equipment for moving the crane bridge, and the other couple of magnetic sensors, switch the starting equipment for moving the crane truck in the same way. A fixed filling drum, which is perpendicular to it and equipped with a carrier gear, is connected to the drum 1. 2 Il.

Description

The invention relates to devices for supplying energy to a mobile consumer, in particular to diesel-electric machines, and provides voltage supply to the traction motors of these machines from an external power source when moving inside the workshop.

The purpose of the invention is to increase reliability.

Fig 1 shows a general view of the device; on Fig 2 - the same, top view of the controller

The device includes a contactless drum 1 with cable 2, mounted on a bracket Ze, which is rigidly connected, for example, with a washing crane trolley (not shown) fed from a flexible cable suspended on a cable along crane runways.

The contactless cable drum 1 is mounted on the shaft 40. The latter, at one end, rests on the sleeve 5, and the other on the bracket 6. On the shaft 4, there is a conical wheel 79 that transmits a torque to the tester driver 8, mounted on a vertical axis 9, fixed at the end of the vertical accumulation drum 10 fixedly mounted on the bracket 30B of the tester-driver 8 there is an opening for the passage of the power cable 2. In the middle of the drum 1 there is a bracket 11 for

fastening cable 2 "i

Ball 4 of drum 1 through coupling 5 and gearbox 12 is connected with electric drive. The diameters of drums 1 and 10 and the gear ratio of bevel gear 7-8 are selected in such a way that

if the length of the cable 2, unwound in one revolution from the drum 1, was equal to the length of the cable, wound on the drum 10.

A bracket 3 is mounted on bracket 3, consisting of body 14, the upper flange 15 of which is a sheet with four figured cuts 16. The bottom flange of the body is bored under the spherical support 17, through which the tube 18 with flared ends is passed. On the pipe 18 fixed ball heap nickname 19 and the ring magnet 20.

The spherical support 17 is closed from the bottom by a cover 21. On the flange 15, four magnetically controlled sensors 22, for example reed-switches, are fastened on insulators opposite cut-outs 16, for example, Receiving cable 2 is attached at the end with a load 23 fixed by brackets 24 and a quick-release 25 outlet

One pair of diametrically located sensors 22 is included in a circuit of time relay coils (not shown), whose contacts with time delay for release switch the starting equipment for moving the bridge on, and the other couple of sensors 22 for switching the starting equipment of the crane truck.

The device works as follows oms

A vehicle, such as a diesel electric, drives up to a building and stops at an open gate. By means of the drive control buttons for drum 1, additionally mounted on the crane, the power cable 2 is lowered. Then, by means of socket 25, they connect the booth | 2 to the plug of the plug connector installed on the vehicle, which continues further movement inside the building, receiving power from the cable 2. Thereby preventing air pollution inside the building (workshop, warehouse). etc.).

When cable 2 pulls up, it turns pipe 18 in support 17. At the same time, ball bearing 19, rolling on cut-outs 16 in flange 15, orients pipe 18 so that magnet 20 enters the zone of action of that sensor 22, which activates the mechanism of movement of the crane towards the movement of the machine. When maneuvering (turning) the cable is relieved of tension, the tube 18 becomes s with the KOTOR magnet 20 removed. The formula of the invention

Claims (3)

1. Device for power supply to the mobile consumer, containing installed on the basis of a non-contact drum with a cable and a kinematically filling drum with a carrier gear, characterized in that, in order to 10 of increased reliability, it is equipped with a drum drive, a commander with a cable passed through, a ring magnet5 of a time relay and associated diametrically 15 arranged magnetic sensors with the ability to interact with an annular magnet located on top of the controller housing, made in the form of a hollow 20 bushes with two flanges, one of which is made with figured notches, opposite of which are magnetically controlled sensors, and the other is spherical, with the base The dates from sensor 22, disconnecting from a standby 25 with drums, are set at auxiliary time of 0.5–1.0 s, the crane drive. Upon further movement of the machine, the cable is again pulled, transferring the magnet 20 to the zone of action of another sensor, including the crane carriage drive in the direction of the machine movement.
