(54) FLEXIBLE MASTERS

The invention relates to the mining industry, namely to devices for laying gabky magastral when working excavation machines.

Known layers flexible lines, including the track chain, one end of which is pivotally mounted on the combine, and the other freely, without fixation lies in the groove 1J.

The disadvantage of such handlers is the intensive abrasion of flexible magastrals due to their bends along an unacceptably small radius and twisting between them.

Devices for laying highways are also known, in which the free end of the track chain is attached in the middle part of the lava 12.

The disadvantages of these devices are their unreliable operation during the development of flat seams and the difficulty of ensuring the safety of service personnel.

The purpose of the invention is to increase the reliability and safety of work.

This is achieved by the fact that in the flexible pipe stacker the drum is made with a cavity

for skipping flexible highways, attached to the washing machine and has a maximum moment drive.

On} shg. i shows the device before turning the drum; in fig. 2 - the same, after turning the drum; in fig. 3 shows section A-A in FIG. 2

The flexible pipe handler has a track chain 1, reinforced at one end with the help of a hinge 2 to the midpoint of the length of the chute 3 located on the conveyor 4 and the other end with the help of the hinge 5 to the excavation machine 6 of the drum 7, driven by a limit cylinder in the form of a hydraulic cylinder eight.

The hydraulic cylinder 8 with the help of the rail 9, Walshaster ™ 10 and the ring gear 11 tells the reciprocating rotation of the drum 7, through the cavity 12 of which the cable 13 and the hoses 14 are passed to the excavation machine 6.

The stacker works as follows.

When the excavation machine 6 is located in one of the extreme positions of its stroke, the drag chain 1, wound around the drum partly and with a fully straightened loop at the hinge 2, lies in one layer in the groove 3. The notch machine moves to the other extreme position, t There is no end of the chain 1, which, bending along a certain radaus, is placed first in two layers, and then - on the other half of the chute 3 - in one layer.

When the excavation machine reaches another extreme position of its course, track 1, except for the incompletely straightened part of the hinge at hinge 2, will lie on the other half of trench 3 in one layer. The part of the hinge at the hinge 2 is not fully distributed, which ensures the power reserve of the excavation machine 6 and eliminates the need for it (J i Ksirovka at a strictly defined place.

When the feed direction of the excavation machine is changed, the limit torque drive 8 is automatically activated, which with the help of a nut 9, pinion shaft 10 and gear ring 1 rotates the drum 7 to one side or the other, depending on the feed direction.

At this time, the part of the truck chain I will be wound on the drum 7, the loop at the hinge 2 will be fully extended, and the truck chain will be tight. When the tension of the traction chain 1 exceeds the specified value, the drive limit

moment 8 is turned off, allowing the drum 7 to turn to the position determined by the position of the end of the track chain and the movement BbF of the capacitor machine in the opposite direction.

The cycle of operation of the flexible highway handler is repeated.
