Description
The utility model relates to the field that is exclusively used in drum cable equipment, especially for the up-coiler on the electric LHD.
The power of underground scraper is selected to have a significant impact for the work efficiency of shovel fortune ore.As use combustion engine to be used as power, and then its institute's exhaust gas discharged seriously polluted to the down-hole finite space directly influences operating efficiency and workers ' health, though when using combustion engine purification mechanism is arranged both at home and abroad in recent years, effect is unsatisfactory; The source if the employing electrical motor is used as power then has a lot of problems to resolve, especially the mode of cable rolling.If the supply cable of electric LHD can not folding and unfolding then can not be used electrical motor under the working condition of down-hole, mine with the scoper operation.
The utility model purpose is: both used electrical motor to make the power resources of underground scraper, the while makes the supply cable on this electric LHD move with scoper again, and the energy automatic deploying and retracting, also will simplify the complex mechanism of trailing cable AC electrical scoper.
The purpose of this utility model reaches like this: utilize the potential energy effect of counterweight and the assembly pulley of being made up of fixed pulley, movable pulley, and the wheel shaft of proportional concentric reel of diameter and axle and shoulder the bar effect, cable is put with the automatic volume of scoper synchronized operation on reel, make scoper in borehole operation can adopt the electrical motor source that is used as power, thereby purpose of the present invention has just reached fully.
Below contrast is elaborated to the design's cable picking and laying machine as the accompanying drawing of embodiment.
Accompanying drawing 1 is the embodiment scheme drawing of the automatic cable picking and laying machine of the design's direct current drive scoper gravity.
The utility model has carried out improving on the basis of diesel engine scoper makes, and therefore, what the design was related only is that the diesel LHD of prior art is changed DC motor and the automatic cable picking and laying machine of this gravity.
From accompanying drawing 1 as seen, the automatic cable picking and laying machine of the design's gravity is by cable drum (1), axle (2), counterweight (3), movable pulley (5), fixed pulley (6), steel cable (4), cable compositions such as (7).Cable drum (1) is concentric with axle (2), and axle (2) two ends difference frame is on bearing support (14), with the weight of carrying cable reel (1), axle (2) and cable (7).One end and the cable drum (1) of axle (2) are fixed together.Cable (7) is two isometric substantially electrode holder lines, one positive one is negative, one end of two statures by cable drum (with) axle (2) respectively with axle (2) on two copper conduction sliding sleeves (8) join, two statures of cable (7) other end are connected with the both positive and negative polarity of power supply respectively by deflector roll (16), and institute's electricity consumption is 275 volts of direct current (DC).Two copper conduction sliding sleeves (8) on axle (2) also contact with two groups of carbon brush (9) respectively, give DC motor (11) 275 volts of direct current (DC) by electric wire (10) again.Counterweight (3) is moved up and down in weight counterbalance operation road (12), and this weight counterbalance operation road (12) is moved head-room and limits, and therefore moves the logical height that highly determines weight counterbalance operation road (12) in lane, and this weight counterbalance operation road (12) is fixed on the scoper rear end.One end of steel rope (4) is fixed on the counterweight (3), and the other end is fixed on the axle (2) afterwards by movable pulley (5) and fixed pulley (6), when axle (2) rotates, drives steel rope (4), thereby drives counterweight (3) up-and-down movement.
This device is to have utilized big roundlet, concentric circles, circular constant and fixed pulley, and movable pulley, assembly pulley, lever, numeral such as wheel shaft, potential energy work done and physical rudimentary knowledge are made by calculating.Because scoper operation head-room is changeless in concrete mine, scoper one way largest motion distance (shovel place, ore deposit is to the distance of black mine) is determined according to down-hole shovel fortune ore needs, after determining, the relation between drum diameter size, shaft diameter size, counterweight weight size, the steel rope length all conditions each other: drum diameter: the move distance of maximum when the diameter of axle equals the scoper operation: the number of share of stock of weight counterbalance operation height * steel rope.The number of share of stock of steel rope is exactly 3 in the accompanying drawing 1, and in a word, above-mentioned each data all condition each other, and can only determine optimum data according to the length and the height of tunnel of one way haul distance.For example want to increase the length of one way long distance, just must increase the length of cable (7), and after increasing the length of cable (7), reel (1) must have been rolled up it again, therefore must increase the revolution of reel (1) again; Perhaps increase the diameter of reel (1).(2) are concentric is fixed together because of reel (1) and axle again, so reel increases revolution, then also along with the same revolution of increase, so steel rope (4) also must extend axle.Be unmodified because of tunnel length again, also be that weight counterbalance operation road (12) is changeless, so can only increase the number of share of stock of the steel rope (4) of bearing counterweight, also must increase the weight of counterweight, otherwise axle (2) can not be put steel rope (4), counterweight (3) can not descending work done, just reel (1) is rolled up motionless cable (4), like this, the purpose of this device is with regard to out of reach, and these data condition each other thus.
When direct current drive scoper operation article operation ultimate range is 100 meters, the operation tunnel only allows counterweight (3) to move 1.7 meters up and down, as bear then 3 * 1.7=5.1 rice of counterweight with 3 strand steel wire ropes, by 5 meters calculating, 100:5=20:1 then also is reel (a 1) diameter: axle (a 2) diameter is that 20:1(sees accompanying drawing 1).When reel (1) diameter is 1 meter, then axle (a 2) diameter is 0.05 meter.
Counterweight (3) is an iron case, puts into for example lead of the bigger derby of proportion therein, can increase and decrease according to circumstances, when adding parent roll (1) diameter, because reel (1) is wheel shaft, concentrically ringed relation with axle (2); Both radiuses are again to shoulder the bar relation, so just must increase the weight of counterweight, counterweight (3) can make axle (2) put down steel rope, and the descending work done of counterweight then can not be rolled up cable (7) as deficiency in weight, when drum diameter is 1 meter; When the diameter of axle was 0.05 meter, the weight of counterweight (3) was about more than 300 kilogram.Generally, electric LHD reaches 100 meters (long 8.75 meters of scopers) at stope, down-hole operation one way distance, such range ability can satisfy the needs of down-hole shovel fortune ore basically, if distance is long, then can influence shovel fortune efficient, therefore, the design's cable picking and laying machine can satisfy the needs of general down-hole shovel fortune ore.
The electric LHD operation of advancing is a payout, and at this moment, cable pulling cable drum (1) rotates, and cable drum drives axle (2) and rotates, axle (2) volume steel rope (4), counterweight (3) upward movement.This counterweight (3) upward movement process also is the process of its energy storage.The scoper fall back, then counterweight (3) moves downward, and it does work with the potential energy that has stored up, and axle (2) is put steel rope (4), and impels axle (2) to rotate, and axle (2) drive cable drum (1) rotates, and cable (7) just twists on the reel (1).As seen in certain range ability, the scrolling of cable (7) is synchronous with scoper fully, also is that the cable rolling function is accomplished moving forward and backward and correspondingly put receipts cable (7) with the scoper operation.Cable picking and laying machine of the present invention all adds loam cake on every side when borehole operation, cable can only be seen in the outside.
For the advantage of the design's cable picking and laying machine is described, several electric LHDs of China is compared see Table 1:
As known from Table 1, the design's cable picking and laying machine is simple in structure, and is reliable, particularly cable picking and laying machine and scoper synchronized operation, automatic deploying and retracting.
Embodiment: direct current drive scoper operation one way operation ultimate range is 100 meters, it is 1.7 meters that the distance of heavily (3) moving up and down only is betrothed in the operation tunnel, use 3 strand steel wire ropes, three strand steel wire ropes are born long 5.1 meters altogether of counterweights, as pressing 5 meters long calculating, then haul distance is long: steel rope length=100:5=20:1, so drum diameter: shaft diameter=20:1.
