Description

one

This invention relates to industrial vehicles and can be used in the mining industry.

The purpose of the invention is to expand technological capabilities and improve traffic safety.

FIG. 1 shows schematically the proposed installation, with the upper disposition of the flexible cable body; Fig 2 is the same with the lower arrangement of the flexible traction organ; in fig. 3 shows successive positions of friction drums with cantilever deflecting pulleys when gripping or disengaging with a flexible pull body.

The installation includes a rail track 1 and a flexible cable body (rope) 2 laid along the longitudinal axis of the train, which for the conditions of coal mines is a set of two to four galvanized ropes with a diameter of 15-20 mm. At the upper location of the traction unit 2, the installation is equipped with supporting devices 3. On the track 1, there is a hinged articulated locomotive 4, which in turn consists of two power sections 5 with diesel-hydraulic units 6 and driving wheels 7. These sections are combined A friction drive 8 comprising a left multi-groove deflecting pulley 9 mounted cantilever on a swinging arm 10, a left horizontal friction drum 11, a right horizontal friction drum 12, a right swing p Seat 13 and the right-hand multi-slotted deflecting pulley 14, Friction drive 8 is also equipped with deflection roller blocks 15, which serve to guide the pulling member 2 through the supporting devices 3 and guide them to the drums 11 and 12. Flexible pulling member 2 at one end rigidly attached to the support of production with the help of a hitch device 16. The second end of the flexible traction body 2 is equipped with a tension device 17, which includes the fixed stationary pulleys 18, the movable pulleys 19, the immobile pivots 20, the clamping devices 21 and ba slaves with a reserve of ropes 22. Tensioning device 17 is made so as to ensure the elongation of the flexible traction body 2 along the

re plowing and carrying the hitch behind it.

The installation works in several modes as follows.

The first mode of operation is moving along horizontal workings. In this mode, locomotive 4 operates as a normal mine diesel locomotive. The movement of the locomotive 4 is carried out from the drive wheels 7 fed from the diesel-hydraulic unit 6. The additional friction drive 8 is not used.

The second mode of operation - moving along inclined workings without side ramps. This mode of operation begins on the horizontal section of the track 1, which is reached by the lower branch of the multi-cable traction. organ 2. The swinging arms 10 and 13 with deflecting pulleys 9 and 14 are raised to the upper position and the locomotive 4 with the composition attached to it is moved by means of the driving wheels 7 towards the flexible rod 2 and goes under it so that both pulleys 9 and 14 were above the ropes. After that, by alternately lowering the swinging handles 10 and 13 (Fig. 3), the ropes of the flexible pulling member 2 are gripped. In this case, the lower branches of the flexible pulling members 2 actuate the tensioning device 1 7 and raise the pulley through the pulley 18 19 with tension load. This ensures a given initial tension of the flexible cable body. The clamping devices 21. fix the second ends of the ropes against pulling. As production is advanced, the cables of the flexible rod 2 are lengthened by the stock on the drums 22, and the hook-on device J6 is transferred to a new location.

After gripping the cables of the flexible traction unit 2 from diesel-hydraulic units 6, power is supplied to the friction drums 11 and 12, which begin to rotate and move along the track 1 locomotive 4 with the train car structure attached to it, B is obliquely disengaged from the locomotive 4 with the flexible tube body 2 is not produced. After reaching a given point and unloading, the locomotive 4 is reversed and returns back in dead ends. During the through movement, it goes out, continuing to move in the same direction, to the horizontal section, where, in the reverse order previously described, it disengages from the flexible traction unit 2 and moves like a regular diesel locomotive.

The third mode of operation - moving along inclined workings with side ramps. In this case, two locomotives mate: one with an upper grip (Fig. 1) and a second with a lower gripper (Fig. 2). At the same time, on an inclined assembly development - a slope, the movement is carried out by a locomotive with an upper gripper of ropes, and the second with a lower gripper operates in lateral branches. The weight rate of the train decreases as the angle of inclination increases. Therefore, this mode of operation is preferably applied at angles up to, i.e. in the so-called dead zone, when there is not yet a stable scooter movement of the train, but it is also impossible to have steady motion on wheels in the mode of traction along the track.

When one of the ropes of the flexible cable body 2 breaks, and there may be 2–4 pieces, the remaining ropes, being independent of each other, ensure that the locomotive 4 is retained from crashing down along an inclined roadway. In this case, the driver slows down the friction drums 11 and 12.

Thus, the advantages of the proposed locomotive transport

compared to the known installation, due to the expansion of technological capabilities and consist in a significant reduction in the number of locomotives required, a decrease in the number of maintenance personnel and an increase in the capacity of the installation.
