Detailed Description
The present invention will be further described with reference to the following examples.
Referring to fig. 1, the preposed counterweight in the prior art mainly adopts a split independent counterweight frame form, that is, two steel wire ropes at the front and the back of a tiebull are respectively an independent counterweight frame, and independent counterweights are arranged on the independent counterweight frames.
Referring to fig. 2-5, the tensioning mechanism of the front traction rope counterweight 10 of the winch traction system of the present invention is composed of a frame 1, a pulley and a counterweight 10 connected and fixed through the frame 1; frame 1 is equipped with left and right landing leg 5, a left side, the top of right landing leg 5 sets up transverse connection frame, transverse connection frame's both ends respectively with a left side, the top of right landing leg 5 is connected fixedly, transverse connection frame sets up fixed pulley 3 respectively in left and right landing leg 5 department of correspondence, set up a movable pulley 2 between two fixed pulleys 3, a left side, all be equipped with on the right landing leg 5 and follow the tensioning pulley 6 of landing leg 5 operation, wire rope 9's both ends respectively with a left side, tensioning pulley 6 on the right landing leg 5 is connected, wire rope 9's intermediate junction movable pulley 2, movable pulley 2's shaft and counter weight 10 are connected.
Because the counterweight 10 is in a suspended state and has no additional running track, the counterweight 10 can flexibly move up and down, and the abrasion and clamping phenomena of the counterweight 10 and the running track can not occur.
The two ends of the transverse connecting frame are respectively connected and fixed with the top ends of the left and right supporting legs 5 through frame body connecting bolts 4.
Through setting up connecting bolt, make the both ends of transverse connection frame be connected convenient, stability is strong with the top of left and right landing leg 5 respectively.
The left and right supporting legs 5 are composed of channel steel arranged in pairs, tensioning pulleys 6 are arranged in groove bodies of the channel steel arranged in pairs, and the tensioning pulleys 6 run along the groove bodies of the channel steel arranged in pairs.
Above-mentioned setting still forms the cell body in order to hold tensioning pulley 6 when being convenient for utilize the channel-section steel to form left and right landing leg 5.
The bottom ends of the left and right supporting legs 5 are respectively provided with an anchor bolt 7 which is fixedly connected with the supporting surface.
The arrangement ensures that the connection between the bottom ends of the left and right supporting legs 5 and the supporting surface is stable and reliable.
The bottoms of the left and right supporting legs 5 are provided with oblique supporting rods.
Through setting up oblique branch, increased the stability of left and right landing leg 5.
The two ends of the steel wire rope 9 are respectively provided with a steel wire rope clamp 8.
By means of the wire rope clamp 8, a good connection can be made to the ends of the wire rope 9.
Because the two steel wire ropes 9 to be tensioned on the two tensioning pulleys 6 are two steel wire ropes 9 at the front and the back of the iron bull respectively, only one rope is in a stretching state during the operation of the iron bull, the other rope is in a following state, the following steel wire rope 9 is loose, and the tensioning amount of the tensioning pulley 6 is large, so that one tensioning pulley 6 is mainly lifted in the operation process. Setting the lifting amount of the single tension pulley 6 to H and the lowering height of the counterweight 10 to H, it is possible to obtain: h is less than 1/2H, wherein H is the lifting amount of the tension pulley 6; h-the lowering height of the counterweight 10. Therefore, when 10 counter weights are designed, the heights which need to be occupied by 10 counter weight bodies and 9 steel wire rope locking buckles and the like considered during the traditional 10 counter weights are not needed to be considered, so that the height of the novel 10 front counter weights can be reduced under the same working condition, the space is saved, and the material manufacturing cost is saved.
After two tensioning pulley 6 share a counter weight 10, the structure of counter weight 10 is greatly simplified, and the counter weight 10 that movable pulley 2 hung hangs in the middle of the frame all the time, no longer needs independent counter weight 10 tracks, and required pulley quantity reduces, the great degree reduction cost of manufacture and the maintenance cost in the future.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all structural equivalents made by using the contents of the specification and drawings are included in the scope of the present invention.
