SU1774422A1 - Current lead for vehicle - Google Patents

Description

The invention relates to monorail transport and relates to the design of current supply devices. used on vehicles in the mining industry.

Known traction device for a monorail threshold, containing a bogie with wheels, a drive that drives the wheels of the bogie, located on both sides of the monorail.

The disadvantage of the known traction device is that there are no means for laying the cable, which is important when using the traction device on curved sections of the monorail and at a considerable distance from the energy source.

A device for winding a flexible power cable on a drum is known, containing a conductive cable and a device for laying it on a drum, including guide rollers moving under the action of an electric motor located on a cantilever frame, and a lead screw for moving along the generatrix of the drum of one of the rollers.

The disadvantage of the known device for winding a current supply cable on a drum is its low efficiency, which consists in the fact that there is an additional auxiliary electric motor for rotating the cantilever frame with guide rollers. Due to the location of the lead screw for moving one of the guide rollers outside the drum along its generatrix, the device has large dimensions.

The purpose of the invention is to improve the efficiency of the device for the current supply to the vehicle.

The specified goal is achieved by the fact that in a device for a current supply to a vehicle, mainly to a monorail, containing a conductive cable and a device for laying it on a drum, including guide rollers moving along the drum under the action of a drive, the drum is fixedly mounted on the trans1774422 frame. A1 of the tailor, and the drive of the guide rollers includes a roller interacting with the monorail, kinematically connected to a longitudinal telescopic shaft passing through the drum, the parts of which are interconnected without the possibility of relative rotation, and one of the parts is connected by means of a threaded connection to the drum body and on it mounted guide rollers.

Figure 1 shows the proposed device, top view: figure 2 - section A-A in figure 1; in Fig.Z - section BB in Fig.2; figure 4 is a section B-B in figure 1; in Fig. 5, section D-G in Fig. 2.

The current supply device to the vehicle contains a current supply cable 1 and a device for laying it on the drum 2, which includes guide rollers 4 and 5 moving along the drum 2 under the action of the drive 3. The drum 2 is fixedly mounted on the frame 6. The drive 3 includes interacting with the monorail 7 roller 8. Roller 8 is kinematically connected with a longitudinal telescopic shaft passing through the drum 2. The kinematic relationship is, for example. a toothed pair 9, connected through a shaft 10 with a toothed pair 11. The longitudinal telescopic shaft consists of two parts 12 and 13, which are interconnected without the possibility of relative rotation, for example, a pin 14 entering the longitudinal groove 15 of the part 12 of the telescopic shaft. Part 12 of the longitudinal telescopic shaft is connected through a kinematic connection to the roller 8, and part 13 is threadedly connected to the body of the drum 2 and rollers 4 and 5 are mounted on it.

The threaded connection is formed by a part 13 of the longitudinal telescopic shaft and a nut 16 connected to the drum 2. The nut 16 is located between the pin 14 and the end face of the part 13 of the longitudinal telescopic shaft.

To distribute the load from the current supply cable 1 along the monorail 7, the holders 17 are located at intervals from each other. The supply of the current supply cable 1 to the holders 17 or removal from them occurs through the guide device 18 with rollers 19 at a speed equal to the speed of the traction device.

The device for the current lead works as follows.

When the drive 3 is turned on, the vehicle moves along the monorail 7. At the same time, the roller 8 begins to rotate, which, through the kinematic link 9-11, drives the parts 12 and 13 of the longitudinal telescopic shaft. Together with the part 13 of the longitudinal telescopic shaft, the rollers 4 and 5 mounted on it rotate. At the same time, during rotation, the part 13 receives a longitudinal movement relative to the nut 16 of the drum 2. Depending on the direction of movement of the traction device, the part 13 of the longitudinal telescopic shaft is either screwed into the nut 16 or unscrewed from her. When this part 13 of the longitudinal telescopic shaft moves up and down relative to the drum 2 guide rollers 4 and 5, which lay the current supply cable 1 on the drum 2 or removed from it.
