The objective of the invention is to expand the scope and increase efforts to move and arrangement of equipment. Our complex includes a continuous miner creeper, spacer-safety device with thrust cylinders and multiple tape cartridges for tightening, the extreme of which is installed on the visor, and the middle one in the Central part overlapping with the spacer beam with slits associated with a visor, and means drilling, anchorage and supply Varnakov roll puff to the place of erection of permanent fastening. Tunnel complex in the rear part provided with a spacer portal support, comprising a beam located above Yoshinari-guides, cylinders thrust beams with bearing skis that are installed on the sides of the harvester and is interconnected to a bottom of the cylinders, shifting frames with caterpillar articulated trucks. The thrust cylinders on top of the freely contact with Yoshinari-guides, realizing self-centering collet support relative to the axis comovement and securing mining.Known continuous miner, which includes swept the Executive body of the rotary device, the overlap with the spacer device, loading the body and tracked progress, the rotary device is equipped with a spacer device, relieving the burden from caterpillars and increasing the stability of the harvester .The drawbacks of such harvesters are:
when the longitudinal length of the overlap over the entire length of the harvester and removing the attachment for combine the effect of "marking time" of the roof, then there are multiple, as you move the harvester, is clamped to the roof overlap with the spacer device, which contributes to the stratification and the collapse of the roof to the place of erection of permanent fastening, this effect appears especially in a weakened roof rocks;
- generated vibration from operation of the tool on the body of the harvester, and then to the Central overlap creates conditions artificial destruction of the roof, overlapping, especially the Central functions of the vibrator with respect to the roof, even in sustainable roofing is its partial collapse, which complicates the subsequent erection of a permanent roof over the combine.Famous tunnel complex  (the prototype is Aspara and multiple tape cartridges for tightening, the extreme of which is installed on the visor, and the middle one in the Central part overlapping with the spacer beam with slits associated with the elastic peak and tools drilling, anchorage and supply Varnakov roll puff to the place of erection of permanent fastening.The disadvantage of this tunnel system is that the scope is limited opportunity crawler on the angles of the generation and created tracks the efforts of thrust (moving vehicles for harvester) and pressure on the face at the nomination with the notch.The purpose of the invention is to increase the effective area of application of the angles of a development, to increase the thrust force for moving equipment in mines with her and releasing pressure on the face at the notch complex.This objective is achieved in that tunnel complex in the rear part provided with a spacer portal support, comprising a beam located above Yoshinari-guides. the cylinders of the thrust beams with bearing skis that are installed on the sides of the harvester and is interconnected to a bottom of the cylinders shifting of frames tracked trucks, and hydraulic thrust on top off the sea harvester.In Fig. 1 shows a tunnel complex, side view; Fig.2 - the same, top view; Fig.3 - the same, rear view along a-a of Fig.4 - tunnel complex with gathering equipment.Our complex includes the working body 1, the loader 2, caterpillar truck 3, remote control 4, the conveyor harvester 5, the thrust cylinders 6 cross beams with skis beams 7 and 8 with slit 9. Front to a beam attached to a hinged visor 10 with slit 11 and the roller 12. The visor rests on a spring or a hydraulic cylinder 13, and on the beam placed the tape roll 15 tightening. Rear beam fitted with handles 16 with hydropolitical 17 by brackets 18, lunettes 19 and by means of drilling 20. Rear beam pivotally connected with Yoshinari-guides 21, which create resistance girder and gantry support made in the form of transverse beams 22, the support cylinders 23, the reference room with the spikes 24, interconnected cylinders shifting complex with 25 frames caterpillar trucks 26. Struts-guides rear connected with the sliding lever support 27, is interconnected with the hydraulic cylinder 23 of the lifting and lowering of uasin. CNC bearing freely to contact with Yoshinari-guides 21 of the cylinder housing 29 mounted on the cylinders of the race is tightening. Struts-guides supplied with the cassette feeder 32 Varnakov to the place of attachment. Cassette feeder is made from a drum with spikes 33, which is constantly in mesh with a rolled puff 31. Cylinder thrust 6 cross beams interconnected to the housing of the harvester hydraulic cylinder resistance and settings 34. To manage the holder has additional panels 35, 36 on the sides of the combine.Tunnel complex works in the following way (without using the portal supports caterpillar tracks).After processing of the face on the magnitude of the removable strip and drilling under anchor harvester moves to recess the next strip after removing from the thrust cylinders 6. During the movement of the harvester roll puff 15 attached at one end to the roof framing with roof bar, leaves the cassettes 15, 31. Sativas from the cassette 31 due to the constant engagement with the spiked drum 33, tightening 37 causes the rotation of the cassette feeder Varnakov 32, summing vernaci to the place of erection of permanent mounting on a certain specified amount. Simultaneously inserted and fixed anchor in the wells, and after stopping the complex roof bar mounted to the anchor is CL repeats.When using the support portal tracked the progress of the disabled truck chain rolls freely (frictional engagement disabled) if the nomination of the combine to the bottom cylinders shifting complex of 25, while the gantry bearing respert between soil and roof framing, and the transverse beam is removed from the thrust cylinders 6, when the visor is in contact with the roof due to the active locking cylinder 13, and reference 7 skis glide over the ground, with the hinged connection of the skis to the frame of the crawler tracks allows the displacement of the ski relative to the reference surface of caterpillars in the vertical plane. After advancing complex CNC bearing is removed from the thrust cylinders 23, with semientered regarding uasin-rails 21, contacting them by cylinder housing 29, and then pulled the cylinders shifting complex of 25, then held apart in the roof, and so the cycle repeats. Removal of the thrust support portal and transverse front beam is alternately excluding their simultaneous removal from spreading at large angles of output.Thus, the support portal allows you to provide a spacer-walking the way of movement, to create the necessary pressure and traction Ne tunnel (the rising generation) and apply it on the circuit of Fig.4 sinking aggregates, moving all control equipment, including the end of the tail head telescopic belt conveyor 38, the battery vent pipe 39 is the interaction with complex node 40 compensate for the offset of the complex relative to the axis of the conveyor belt.To prevent collapse anchors beam gantry supports and the transverse beam with a peak, the width of the beams is made a multiple step shifting and the value of a single notches working body in the bottom output. This embodiment also eliminates the trampling of the roof, as it provides a single contact beams from the roof along the length of the output.Sources of information
