Abstract
The utility model relates to a cable picking, laying and managing device of an electric dragging carry-scraper for a mine. Two opposite rectangular screw threads are machined on a reverse-flighted screw, two ends of the reverse-flighted screw are respectively provided with a bearing and a driven chain wheel, and the reverse-flighted screw is arranged on a lead screw support; a slide block and a copper lining are sleeved at the middle part of the reverse-flighted screw, vertical holes of the slide block are respectively sleeved with a shifting fork and a spring, the circular-arc surface of the shifting fork clings to the bottom diameter of a screw thread groove of the reverse-flighted screw, and the shifting fork can only move along the inside of the screw thread groove; and a cable jacket is arranged in a lower hole of a connecting plate, and a cable passes through the inside of the cable jacket. The driven chain wheel drives the reverse-flighted screw to continuously do rotational motion to ensure that the shifting fork in the slide block does one-way motion along one thread line of the reverse-flighted screw, when the shifting fork moves to the end points at two ends of the screw threads, the shifting fork does opposite motion along the other thread line after passing through a transitional screw thread, the reverse-flighted screw continuously rotates to enable the shifting fork to do two-way reciprocated motion, the cable is enabled to do two-way reciprocated swing through the connecting plate and the cable jacket, and thus, the effect of ordered cable management is achieved.
Description
Technical field
The utility model relates to a kind of mine cable draw off gear, particularly a kind of mining towing electric LHD twisted and released of the cable spooling gear.
Background technology
All the time pulled a long cable in the middle of the work of mining trailing type electric LHD is moved, cable winding will guarantee that along with scoper seesaws cable carries out synchronous folding and unfolding in reel; When electric LHD retreated, the cable rolling is in reel, and was neat in order to guarantee cable maximum range ground rolling cable and hierarchal arrangement, must the design cable sector.
In the past during some electric LHD twisted and released of the cable owing to there not being the designing and arranging cable device, therefore cable arbitrarily twines in reel, and the cable irregularity twines, and inhomogeneous, the cable of cable tension is in length and breadth to distortion in the time of can causing the folding and unfolding cable, easily damage cable, also can add the external diameter of parent roll simultaneously.
The twisted and released of the cable spooling gear of electric LHD all adopts row's cable mode of reverse-flighted screw mostly both at home and abroad, rotatablely moving of reverse-flighted screw drives the axial motion of shift fork, cable clamp is moved back and forth along the Width of reel, thereby cable fitly is arranged on the reel.But be used for wearing the revolving wheel that the cable clamp that presss from both sides cable adopts into the biconjugate roller mostly, becoming biconjugate roller revolving wheel joint portion very easily cable to be produced extruding, cutting, cable had great damage.
The utility model content
The purpose of this utility model is to provide a kind of mining towing electric LHD twisted and released of the cable spooling gear that can neatly arrange cable, reduce cable fault.
The technical solution of the utility model is: a kind of mining towing electric LHD twisted and released of the cable spooling gear, and reverse-flighted screw is installed on the screw mandrel bearing, and deep groove ball bearing and driven sprocket are set in the two ends of reverse-flighted screw; Reverse-flighted screw centre portion suit slide block and copper lining are installed shift fork in the upright opening of slip front section, be set with orienting sleeve on the axle journal of shift fork, and shift fork can rotate freely in orienting sleeve, mounting spring in the shift fork end hole; Connecting panel and slide block are rigidly connected, and under the effect of spring force, the arc surface of shift fork is close on the footpath, the end of reverse-flighted screw thread groove; Cable joint-box is nested in the connecting panel underpunch, fixes with back-up ring; Cable directly passes from cable joint-box.The square thread of two opposite directions of processing on the described reverse-flighted screw 7.Described slide block 17 trailing flank in moving process contacts with the backing block 6 that is installed in screw mandrel bearing 18 centre portions.Described shift fork 12 directly fits tightly with the end of reverse-flighted screw 7 threads groove under the effect of spring 11 spring forces.On described connecting panel 1 front end face lubricator cup 14 is installed, the lubricating cup tapped bore directly communicates with the inner chamber of reverse-flighted screw 7 threads groove.
The beneficial effects of the utility model are:
1. process two-way square thread in the utility model on the reverse-flighted screw, can realize effectively that the bidirectional reciprocating of shift fork moves, thereby guarantee that the cable bidirectional reciprocating swings, to reach the effect of neat row's cable;
2. the backing block that is installed in screw mandrel bearing centre portion in the utility model can prevent effectively that limited slip block rotates the phenomenon of swing in moving back and forth process;
In the utility model under the effect of Compress Spring, the end of shift fork and reverse-flighted screw thread groove, directly fit tightly, the screw thread reliable transmission, and can auto-compensation the wearing clearance of shift fork circular arc;
4. on the connecting panel in the utility model lubricator cup is installed, the butter of regularly annotating can reduce the wearing and tearing of shift fork and reverse-flighted screw effectively, prolongs the service life of shift fork, and more is conducive to the flexible movement of shift fork in the Bidirectional-screw thread groove;
5. cable joint-box adopts one-piece construction, and cable directly passes from cable joint-box, has effectively avoided the generation to the phenomenon of cable pinch cutting.
