Abstract
The utility model belongs to an electric cable-winding and unwinding device used for an electrodynamic scraper. The existing cable reel supported by double arms is changed into the cable reel supported by a single arm; a slip ring is arranged in the reel; the slip ring and a brush carrier are made as a whole; a protecting cover is arranged on outside to form a slip ring sealing chamber which is free from the interference of external environmental condition; the slip ring material of polytetrafluoroethene with good abrasive resistance and insulating property is selected. The utility model has the advantages of original design, reasonable disposition, good operating performance and convenient maintenance, having an application for an ideal electric cable-winding and unwinding device.
Description
The utility model belongs to a kind of cable reel installation that uses on the electric LHD.
Cable reel installation great majority on the electric LHD are both arms carrying cable reels at present, and this configuration flexibility is poor, particularly change quite difficulty of consumable accessory and maintenance.The utility model is the cable unit that overcomes the unreasonable a kind of novelty that designs of said structure.It not only guarantees the mobility of electric LHD work, flexibility, and cable can act freely with the electric LHD advance and retreat synchronously simultaneously, and cable does not produce surplus dragging and rolling, and main is the stretching of having avoided super cable intensity.
The utility model adopts single armed carrying cable reel, installs collector ring component in spool body, and safety guard is installed in the outside, with seam centering and sealing, forms the collector ring closed chamber that not disturbed by external environmental condition.The transmission adopted enclosed construction, cable access and tube arm threading position rubber sealing device.For the ease of maintenance, maintenance or replacing collector machine, collector ring and brush holder are done suite, as long as tear several screws like this open, can wholely take out or install.When cable drum is worked, be relative motion between slip ring and the brush holder, the utility model selects for use other part is few, geometry is simple, regular slip ring as the kinetoplast that rotates with reel, thereby greatly reduces the fault chance.
The insulating material polytetrafluoroethylene of collector ring does not contact body in order to make cable in the folding and unfolding process, reduce sliding friction, and unlikely scratch cable sheath adopts outlet down; Guider has replaced four idler pulleies with two guide wheels, and the protection cable has been played good effect.
Fig. 1 is a hydraulic control coefficient schematic diagram, (1) oil motor among the figure, (2) oil pump, (3) electro hydraulic valve, (4), (5) overflow valve.
Fig. 2 is the drive system schematic diagram, (1) oil motor among the figure, (6) external gear, (7) internal gear, (8) cylinder.
Cable reel installation and the synchronous operation principle of electric LHD advance and retreat:
Shown in accompanying drawing 1,2, when behind the electric LHD during debatching cable, electro hydraulic valve (3) the right is logical, and oil pump (2) directly drives oil motor (1) and rotates, and this moment, oil pump (2) pressure was controlled by overflow valve (4); When electric LHD advances payout, the tension band movable reel (8) that is produced by cable reverses, oil motor this moment (1) also reverses and becomes the operating state of pump, from oil motor (1) import oil extraction, at this moment electro hydraulic valve (3) left side is logical, and the motor oil extraction produces the press-brake oil motor through electro hydraulic valve (3) to overflow valve (5), makes the speed and the scraper walking synchronization of payout, at this moment oil pump (2) emptying reduces energy consumption and heating.When electric LHD slows down and shovel the fortune ore, though be direction of advance, but the motor reverse speed decreases even is bordering on zero-speed, can not produce braking when pressing, then electro hydraulic valve is in the centre position, and oil pump (2) with the work of brake pressure state to the motor fuel feeding, overcome the cable drum counter-rotating, make cable still keep certain force of strain, the possibility of avoiding wheel to roll cable restarts for retreating simultaneously.
The cable rotating cylinder is by the engagement of the little external gear (6) on oil motor (1) axle center in internal gear of cylinder (8) one ends (7) and the hydraulic system, thereby drives reel.
The utility model and the coupling of SDC-1 type electric LHD have been carried out commerical test in Western Hills Gypsum Mine S-05 exploiting field, Taiyuan, insulating properties and functional reliability to servo-actuated, automatic deploying and retracting effect, cable outlet direction, wire installation and the collector ring of cable drum are examined or check, the result shows, realized twisted and released of the cable and electric LHD advance and retreat synchronously, servo-actuated is good.Collector ring insulating properties and resistance to wear are all fine, and the collector ring sealing is immersion and dust intrusion not, has illustrated that sealing is good.Surplus dragging and the rolling phenomenon rationally do not take place in outlet direction and guider configuration.
Advantage of the present utility model:
1. novel structure, twisted and released of the cable freely, and with the electric LHD advance and retreat synchronously.
2. single armed carrying cable reel, collector ring and brush holder constitute whole, assembling, maintenance and safeguard all very convenient.
3. good seal performance is not soaked and the dust penetration phenomenon in the reel.
4. the collector ring insulating material is selected rationally, and is safe and reliable.
Claims (3)
1, the synchronous cable reel installation of a kind of hydraulic drive and electric LHD advance and retreat is characterized in that single armed carrying cable reel.
2, cable reel installation according to claim 1 is characterized in that in the cable drum that single armed supports collector ring being housed, and collector ring and brush holder are done suite, can whole assembling or taking-up.
3, cable reel installation according to claim 2 is characterized in that said collector ring makes with the polytetrafluoroethylmaterial material of resistance to wear and good insulating.
