Description

 The invention relates to lifting and handling equipment, in particular to devices for flexible current supply and a movable power receiver.

A device for supplying energy to a movable object is known, comprising a guide cable located along the monorail of the power receiver, a split pipe supporting the cable in its middle part from sagging and fixed with a rod and fasteners on the monorail, carriages mounted on the guide cable with the possibility of movement through it through a split pipe and connected by a traction cable to each other and with an electric receiver, and suspensions mounted on carriages [1]
However, the known device has insufficient reliability in operation, since the carriage in the form of a flange roller with a cylindrical groove and anti-tipping emphasis do not form a closed loop around the guide cable. When the carriage passes through the split pipe, it falls at the exit of the beveled end of the pipe from the interaction of the anti-tipping stop with the stand on which the pipe is fixed.

 On the way back, the carriages come closer, move along the cable in the form of a continuous link. At the same time, individual carriages bulge upward, their anti-tipping stops are higher than the beveled end of the split pipe, when passing through the pipes, they capture the guide cable and drop it through the upward facing groove outside the pipe, which creates an emergency.

 The purpose of the invention to increase the reliability and safety of operation of the device.

 This is achieved by the fact that the device is flexible current supply to the movable power receiver, containing a guide cable located along the monorail of the power receiver, a split pipe supporting the cable in its middle part from sagging and secured with a rod and fasteners on the monorail, carriages mounted on the guide cable with the possibility of moving along it through a split pipe and connected by a traction cable to each other and with an electric receiver, and the suspensions mounted on carriages are equipped with a sleeve having conical ends and fixed with a locking screw on the cable inside the split pipe, the latter being located on the shaft with its groove facing down and made with input chamfers on the inner surface and groove walls, and each carriage contains a closed ring and pivotally mounted on the bottom the bow of the ring a spherical head with a cylindrical neck, connected by means of a thread and a lock nut with a suspension and located with the possibility of interaction with the sleeve and the input chamfers of the split pipe when enii through the last.

 In FIG. 1 shows a device for flexible current supply to a movable power receiver, general view; in FIG. 2, section AA in FIG. 1; in FIG. 3 node I in FIG. 1; in FIG. 4 a section BB in FIG. 2.

 The device for flexible current supply to the movable power receiver contains a guide cable 1 located along the monorail 2 of the power receiver 3, a split pipe 4 supporting the cable in its middle part from sagging and secured with a rod 5 and nuts 6 on the monorail, carriages 7 mounted on the guide cable with the possibility of moving along it through a split pipe and connected by a traction cable 8 to each other and with an electric receiver, and suspensions 9 mounted on carriages and carrying a flexible cable 10.

 The device is additionally equipped with a sleeve 11 having conical ends 12 and fixed with a locking screw 13 on the cable inside the split pipe.

 The split pipe is located on the rod 5 with its groove 14 facing down and made with inlet chamfers 15 and 16 on the inner surface and the walls of the groove.

 Each carriage contains a closed ring 17 and a spherical head 18 pivotally mounted on the lower arch of the ring with a cylindrical neck 19 connected by a thread 20 and a lock nut 21 with a suspension 9 and arranged to interact with the sleeve and input chamfers of the split pipe when passing through the latter.

 The traction cable is fixed in the holes on the necks with the threaded end of the suspension 9 and is connected to the power receiver 3 through the lead-pusher 22.

 A flexible current supply to a movable power receiver operates as follows.

 Guide cable 1 is pulled along the monorail 2 of the power receiver 3.

 The split pipes 4 supporting the cable in its middle part are fixed on the monorail using a rod 5 with a threaded end and nuts 6. Such fastening allows the split pipes to be positioned at the required distance from the monorail and in line with the guide cable, which simplifies installation. The presence on the sleeve of the locking screw 13 allows you to fix it on the cable inside the pipe. Access to the screw is provided from below through slot 14, which also facilitates installation.

 When the electric receiver moves along the monorail forward, the cable 8 is pulled, forcing the carriages 7 to move along the cable 1 and, using suspensions 9, move the flexible cable 10 behind the electric receiver.

 Since the carriage moves along the cable by means of a closed ring 17, its fall is excluded.

 When passing through a split pipe, the ring from the cable passes to the sleeve along its conical end. In this case, the spherical head 18 with the cylindrical neck 19 is guided by the input chamfers 15 and 16 into the pipe.

 When the head passes inside the pipe, the ring and the sleeve are unloaded from the weight of the cable, which eliminates pinching of the head between the sleeve and the groove.

 Due to the normal non-cantilever arrangement of the suspension on the carriage, the cylindrical neck does not bend, it passes through the groove through the split pipe unhindered.

 On the way back, the carriages are shifted by the lead 22. In this case, the flexible cable and the pull cable are assembled into loops. Spherical heads come together, but not close to one another, since the diameter of the heads is less than the distance between the loops of the assembled cable. The carriages pass through the split pipe in a sequential order, similar to their passage when the electric receiver moves forward.

 If the guide cable is loosened, the sleeve fixed on it may be outside the split pipe. However, an accident will not occur from this, since the split pipe is located on the rod with its groove facing down, and the carriage in the form of a closed ring will move along the weakened cable under the split pipe.
