Description
Technical field
The present invention relates to the belt conveyer that uses under a kind of coal mine.
Background technology
Belt conveyer is because operational throughput is big, fed distance is long, safe and reliable, degree of automation is high, easy maintenance, recurrent expenses is low, applied widely, under China every profession and trade widespread use, particularly coal mine more than 90% is to adopt belt conveyer as transportation means.The middle and small scale coal mine of China southwestward is mainly the mountain region inclined seam, because thinner, the coal seam branch complexity in coal seam, the space of underworkings is subjected to investing the restriction with the coal seam, and large-scale efficient delivery system can't be installed, and generally adopts belt conveyer; Existing belt conveyer comprises frame, is located at upper and lower two-layer carrying roller, driver train, tensioning changed course mechanism, adhesive tape, stern barrel on the frame, frame comprises rectangular frame and several supporting legs, and driver train includes motor, retarder, coupler and the cylinder of being located at the frame head; Tensioning changed course mechanism comprises cylinder, tension car and the guide rail more than three, and tensioning changed course mechanism cylinder foremost is loaded on the tension car, and an end of a steel wire connects with tension car separately, and the other end is around on the pulley, and this pulley links to each other with the piston rod of oil cylinder; Adhesive tape is around on all cylinder and carrying roller, and carrying roller is loaded on rectangular frame or the supporting leg by the installation shaft at two ends.
The common arrangement separate unit is arranged belt conveyer on the underworkings base plate at present, if arrange two equipment, the tunnel need enlarge about 1 times, installs on the roadway floor side by side to guarantee equipment level.Domesticly in recent years the mining double-deck belt conveyer that transform voluntarily in the colliery occurred seldom measuring, its arrangement form is that two belt conveyers are arranged up and down, has realized saving the purpose in tunnel.It is two kinds of fixed type (as Fig. 1) and suspension types (as Fig. 2) that its keystone configuration form is divided into the middle part carrying roller, two-layer equipment all has independently actuating device, carrying roller, tensioning changed course device, stern barrel, adhesive tape etc. up and down, rely on the friction force of the driving drum of adhesive tape and driver train drive to make adhesive tape do the continuous closed-loop running, realize afterbody charging, head discharging, reach the purpose of convey materials.
More than two kinds of equipment all form the transformation of standard belt conveyer, in order to satisfy driver train and the tensioning changed course arrangement of mechanism of two-layer equipment up and down, have to the height of belt conveyer upper strata belt conveyer driver train to (particularly lower floor's belt conveyer driver train and stretching device place) between the belt conveyer tensioning changed course mechanism of lower floor improved, the equipment installation difficulty strengthens, height increase along with equipment, the safety of equipment operation, the corresponding reduction of stability, and because the device height increase, carry height of tunnel also to need corresponding increase, increased roadway construction difficulty and investment cost.Simultaneously its actuating device, tensioning changed course mechanism and frame width are too wide, need take People's Bank of China or the access path in tunnel, give the back personnel and make troubles by, overhaul of the equipments and material delivery.The equipment that has is arranged on the belt conveying drive end unit to reduce the height of stretching device position with the tensioning mechanism that alters course, to save the tunnel investment, but because the distance of tensioning changed course mechanism and driver train is longer, tension force provides needs a period of time, therefore the cylinder tension force of adhesive tape and driver train is less when device start, cause friction force less, the phenomenon that adhesive tape skids very easily occurs.
The double-deck belt conveyer of suspension type is that two suspension type belt conveyers are arranged in up and down on the same roadway floor, as shown in Figure 2, two supporting legs 50 of adhesive tape both sides correspondence link to each other with snub pulley 52 by upper and lower two-layer flute profile carrying roller 51, because flute profile carrying roller 51 is suspension type, the adhesive tape distance is less up and down, the double-deck back device height of installing is lower, and less demanding to the tunnel, its version is simple economy comparatively; But because hanging carrier roller 51 can't be installed aligning carrier roller, the carrying roller resistance is big, cause equipment failure rate height, the easy sideslip of adhesive tape, equipment energy consumption height, transport efficiency lower; Simultaneously because double-deck belt conveyer center of gravity is higher, its hanging carrier roller structure is activity form owing to carrying roller; under the situation of startup, shutdown, rubber belt from deviating, load change; carrying roller 51,52(be the upper strata carrying roller particularly) can swing vibration and the distortion that cause frame with the external force effect, there is big potential safety hazard.Owing to do not have and prevent that adhesive tape is concave arc section lower floor adhesive tape ribbon (being lifted because adhesive tape is tauted when moving from bottom to top), carrying roller 51 is not for there being fixing hanging structure form in addition, this equipment can't be realized moving under the change gradient condition of concave arc, convex arc etc., can only realize that 2 straight lines carry; Its supporting leg 50 adopts bolt of rear end plate to be connected with rectangular frame, because the down-hole is with a varied topography, belt conveyer height of landing leg and spacing are subjected to the landform variable effect bigger, bolt of rear end plate connects can't carry out corresponding adjusting, cause the belt conveyer zone face to be uneven, the installation of this equipment rectangular frame and supporting leg 50 simultaneously, adjustment, maintenance and dismounting later on are all inconvenient.
The double-deck belt conveyer of fixed type is that two common belt conveyors are arranged in up and down on the same roadway floor, as shown in Figure 1, two supporting legs 55 of adhesive tape both sides correspondence are equipped with upper and lower two-layer erecting frame 56, each layer erecting frame 56 links to each other with snub pulley 59 by flute profile carrying roller 57, linear pattern support 58, it is higher that the back device height is installed, device security hidden danger is big, poor stability, and common head-room can't satisfy the equipment needs simultaneously, and needing to expand high tunnel could install.Do not prevent adhesive tape concave arc section lower floor adhesive tape ribbon (being lifted because adhesive tape is tauted when moving from bottom to top) owing to have, this equipment can't realize that concave arc, convex arc etc. move above under 6 ° the change gradient condition; Snub pulley 59 is installed as the draw-in groove form, and the installation shaft at snub pulley 59 two ends is easy to jump out from draw-in groove in operational process, is prone to the situation that snub pulley drops; Its supporting leg 55 adopts bolt of rear end plate to be connected with rectangular frame, because the down-hole is with a varied topography, height of landing leg and spacing are subjected to the landform variable effect bigger, bolt of rear end plate connects can't carry out corresponding adjusting, cause the belt conveyer zone face to be uneven, the installation of this equipment rectangular frame and supporting leg 55 simultaneously, adjustment, maintenance and dismounting later on are all inconvenient; Above-mentioned each belt conveyer has seriously restricted the raising of coal mine output, so coal mining enterprise presses for a kind of conserve space, freight volume is big, safety performance is high conveyer.
