SU1230472A3 - Protective and guiding device for traction member and supply lines of breaking winning machine - Google Patents

Abstract

Protection and guidance means for traction drive means and energy supply lines of a mineral extraction machine comprises two separate channels (3, 3') for the reception of a drive run and a return run of the traction drive means, a longitudinal slot arranged in the region of the drive run channel (3) for the passage of abutment means of the machine, and a further channel (5) for the supply lines, the further channel extending parallel to the traction drive means channels (3, 3') and being screened off from the travel field. The longitudinal slot is blocked at one or more locations in a length section of the protection and guidance means by a latching device (11) actuable by the machine. The channels (3, 3', 5) are defined by three members (8, 9, 10), the screw connections of which point laterally towards the travel field. The base of the channel (5) for the supply lines consists of individual web-like frame elements (18). <IMAGE>

Description

The invention relates to a protective and guiding device for conveying the organ and the feeding lines of the mining machine, which has a stop under the conveyor plate, and to be used in outdoor equipment,

The purpose of the invention is to improve work safety and simplify the design.

FIG. 1 shows the device in the bottom cross-section ;; figure 2 - device, cross section; in fig. 3 - one-piece locking device; in fig. 4 - composite locking device.

The executive body of the mining machine 1 performs a reciprocating motion along the downhole conveyor 2. On the downhole conveyor 2, from the developed space, channels 3 and 4 are located for the traction body, in which there are working 5 and single 6 branches. Adjacent to channels 3 and 4 for traction organs is channel 7 for feeding lines 8.

The sub-conveyor plate 9 of the executive body of the mining machine 1 covers the bottomhole conveyor .2 from below. Channels 3, 4 and 7 consist of three bolted elements 10-12. Element 10 intersects the supply lines 8 from above and serves as a casing for the idle branch b and the working branch 5 with respect to the bottomhole conveyor 2, in addition, it separates the idle branch 6 from the working branch 5, the second element 11 serves on the side of the screen for the feeding lines 8 in relation to the section 13 of the movement and the soil of the plate, it covers the working branch 5 from below. The third element 12 separates the supply lines 8 from the branches 5 and 6 of the trunk organ using a blocking device 14.

- The bottom of channel 7 for feeding lines 8 consists of frame elements 15.c

in the form of spacers, along which the feed lines 8 pass. On the upper side of the frame elements 15, plastic coatings 16 can be used to facilitate the glide of the power lines 8. In addition, support rollers 7 can also be installed between the spacers, on which the power lines are located.

The joints of the sections of the protective and guiding devices are shielded by means of flexible coatings (not shown) with respect to the moving section 13. This makes it possible to close the gaps formed during the bending of the forward branch.

FIG. Figure 3 shows one of the blocking devices 14, overlapping a longitudinal section 18 between the channel 3 for the coupling member and the channel 7 for the supply lines. The locking device 14 has the form of a single pivot arm 19 with downward ends 20 and 21. The pivot arm 19 can be displaced up and down on the axis 22 by the abutment of the sub-conveyor plate 9 of the mining machine, penetrating through the longitudinal section 18. At the bottom end, the pivot arm 20 extends 19 rises, while the other end 21 goes down. In this way, the frontal slit 18 is removed only upon contact with the conveyor plate 9.

In another embodiment, the device 14 (Fig. 4) consists of several elements, namely, two valves 23 and 24 and a rotatable lever 26 located above them on the wasps. One of the slide valves 23 sliding along the guide rail. it is lifted by the support of the conveyor plate 9, while the other valve 24 of the locking device 14 is displaced by the pivoting lever 26 in a downward direction.
