How to rectify the face conveyor with hydraulic drive bay slide
In the event of fall accidents can tune oblique upward traction Discovery delivery machine, adjust downward hydraulic support solutions. Off sharp words mechanized mining
face conveyor hydraulic support mechanized mining face conveyors and hydraulic support widespread over the course of the decline. Rack fell seriously affected
Face normal production, ranging from the lower trough no safe exit, heavy face need to be in the lower end of the withdrawal of hydraulic support and conveyor chute.
Face conveyor reasons for the decline in the use of the process, because of their weight, Shearer row of reaction and downhill transport and other reasons, to promote the
conveyor will produce a small downward displacement. This shift has led Jack and bracket goes down skew. When deflectedPlastic belt conveyor
Jack goes along the conveyor when the deflection direction, but also increased the amount of decline conveyor. The jack skew angles and with the increasing decline conveyor,
hydraulic support, will also be forced to change the forward direction, this direction appear slight decline.
So repeatedly, conveyors and brackets will gradually decline in the amount accumulated. When the conveyor decline schematic diagram cut over the top ahead of the lower end of
the conveyor, the conveyor by a force and a former hair downward force, downward force, forcing down the conveyor in an accident
Slip prevention conveyor means from the face conveyor head start with a set distance intervals slip device. Use non-slip jack jack stand goes, ends with a small ring chain were
fixed at the top bracket base and chute bottom bezel. Jack Yu-shaped cavity design hydraulic lock
And safety valve, to increase the tension of the conveyor and to prevent damage to the jack. The number of anti-skid device according to the weight of the conveyor, face angle
and traffic volume to determine the actual situation. Bottom bracket No. sitting at the end of a front-end design with the same conveyor skid slip device. Backend
Office, located a group of four-bar linkage skid, anti-slip dry pounds of top bracket front spar jack, coupling methods and methods for liquid slip device with the same
conveyor. Pull the 1st rack, use two sets of skid control its decline, numbers do not stand down, while the other frame in the frame shift will greatly reduce the decline
Possibilities. Face tune into the so-called oblique oblique face one end than the other end is a certain distance ahead, generally lower ahead of the upper part of a face,
oblique angle so.Extendable conveyor
North Face ore mining early years when the cut length, angle, cut the top ahead of the bottom. Our measures are at the lower end face fewer mounting brackets, using a long steel
beam with single columns supporting the roof. Mined and then began adjusting ramp, brackets and conveyor decline, withdraw at the lower end
A conveyor chute, long beams and single pillar, avoiding the withdrawal of the stent difficult. Before the end face, face cut and stop line not parallel, but also need to adjust
ramp. In most cases is the need to tune into the original positive oblique oblique, this situation will force the conveyor decline, often
Will not stop mining working face conveyor line position has slipped under the nose along the ledge, unable to produce. In this case, adjust the ramp time in addition to taking
regular anti-slip, but also need to play in the head at point a truncated column to control the conveyor decline. Replaced by a two-way one-way cutting coal coal cutting
Downlink shearer cutting coal, frame shift, clear live coal on the line, the top slide. Push the slide when the first push the nose, and then turn upward slide.
According to the measurement, each slide can push a conveyor Shangcuan 30-40mm. While avoiding the downpipe from the tail goes down when the downward thrust, can effectively
prevent the conveyor decline. Decline in incident handling mechanized mining face if taken over anti-slip, fall generally does not occur
Accidents. If the measures are not effective, there was decline in accidents, the following measures can be taken to deal with. Only into the lower end of the inclined face
tune, ramp up in the head at selected crop. After adjusting ramp looking straight face conveyor. With this approach, every tune knife, the nose can Shangcuan so. Method is to
Downpipe not loose slip jack, push the slide work in the non-slip upward pull the jack under. In this way, each into a knife, can move on the conveyor tractor clever.
If the face angle, the effect is not obvious, the increased number of non-slip jack. Note that using this method is that you must use high-quality anti-skid chains jack
connection on both ends to connect reliably to prevent accidents. Timely adjustment of hydraulic supports in tune decline
The entire conveyor, we must adjust the hydraulic support fell, the method can be used stand-by-side shields interaction rack rack upwards. If it is local stand down, you can
drop down bracket column, its base with a jack up top.
