Detailed description of the invention
Do to know to the utility model by reference to the accompanying drawings below by way of preferred embodiment and intactly illustrate.
As shown in Figure 1, the steel wire rope pre-tightening device that the utility model proposes, it includes reel 101, brake equipment, support 102, needle bearing 105, base 104.
Support 102 is flexibly connected with described reel 101, and support 102 is for supporting described reel 101 and making described reel 101 freely rotate.Brake equipment is in the side of described reel 101, and brake equipment is for controlling the suffered application force of reel 101; Needle bearing 105 is arranged at below reel 101 and contacts with reel 101.Brake equipment, described support 102, needle bearing 105, to be all placed on base 104 and to be fixedly connected with base 104.In the present embodiment, described in each, reel 101 periphery is provided with a brake equipment.In order to support 102 removes and installs conveniently, between reel 101 and support 102, be provided with plain bearing.Take between support 102 with base 104 to be detachably fixedly connected with.Base 104 is made up of I-section profile.
In the present embodiment, the spool on reel 101 and adopt between support 102 and inlay graphite self-lubricating plain bearing and assemble.Adopt bolt to be connected between support 102 with base 104, after unclamping the bolt of travel(l)ing rest 102 and base 104, support 102 can be taken off easily.
As shown in Figures 2 and 3, reel 101 comprises the solid drawn pipe 1011 of closed at both ends, is placed in solid drawn pipe 1011 center and makes its rotary drum shaft 1012, be arranged at the dividing plate 1013 of solid drawn pipe 1011 surface A.The setting of dividing plate 1013 makes reel divide in order to two parts, and a part is the brake wheel 110 contacted with the brake collar 107 on brake equipment.Another part is then steel wire contact area, and its surface A is provided with the grooving 1014 for accommodating steel rope.In the present embodiment, surface A is provided with a plurality of described grooving 1014.Grooving 1014 quantity some (general employing 7 can meet friction force needed for most of steel wire tensioning).Grooving 1014 is lathed type after solid drawn pipe 1011 welds round steel, greatly can reduce like this and manufacture grooving 1014 cost, adopts the non-helical formula of circumference to reduce the welding precision difficulty of grooving 1014, and grooving 1014 can independent car system, reduces difficulty of processing.
As shown in Figure 1, brake equipment comprises roller 106, ratchet handle 103, brake collar 107; Brake collar 107 is coated on nearly 3/4 week of the surface A of reel 101 and the close contact of reel 101.Ratchet handle 103 is flexibly connected with roller by connecting rod 108, and brake collar 107 is fixedly connected with described roller.By pulling ratchet handle 103, ratchet handle 103 drives roller to rotate; Roller rotates rear and then tension brake collar 107, and brake collar 107 is tightened up in the surface A of described reel 101, and then the effect that realization control reel 101 rotates.
Support because reel 101 increases needle bearing 105, after dismantling a side stand 102, reel 101 still can low load rotate, and steel rope is inserted in reel 101, and which solves steel rope cannot be fit into reel 101 difficult problem.
Steel rope is installed on steel wire rope pre-tightening device and divides following two kinds of situations.One, cable wire end is not installed on winch, and fag end directly penetrates after two reel 101 reels back and forth and is being fixed on winch.Two, the steel rope for traction is very long, and the steel rope in reel 101 also has a lot, cannot again draw cable wire end access to plant as the first situation.At this moment the mode that stripping assembly support 102 is inserted in steel rope is from the side adopted to realize: the bolt of striking 102 and base 104, take off support 102, steel rope coils into a circle on the ground, number of channels needs winding number in device to determine according to plan, then by steel wire loop on two reel 101, again support 102 cover is got back in drum shaft 1012 after dividing grooving 1014 marshalling, binding bolt can complete installation.Steel wire tensioning power size is determined by windings in reel 101 and brake equipment braking force size.
The utility model propose steel wire rope pre-tightening device, during use, be connected to from steel rope reel lax steel rope out after steel wire rope pre-tightening device on lifting drum, lifting drum rotates and tightens up steel rope, and by braking generation antagonistic force, steel wire rope pre-tightening device ensures that the steel rope entering lifting drum is all tight state.
Reel back and forth after steel rope enters pre-tightening apparatus multi-turn between two reel, ensure that steel rope all has enough friction force with two reel, when lifting drum rotates, the two reel of pre-tightening apparatus also rotates, and can realize steel rope predetermincd tension size adjustment by regulating the braking force size on two reel.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that this is only casehistory, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
