Abstract
The utility model relates to a steel wire rope hydraulic tensioning device, in particular to a steel wire rope hydraulic tensioning device which is capable of singly tensioning steel wire ropes by groups used for a steel wire rope conveying belt vulcanizing machine; the device comprises a frame and a set of guide wheels which are hinged with the frame and horizontally arranged to the traction and tension of the steel wire ropes; a lifting rod driven by a tensioning oil cylinder is arranged between the guide wheels; the upper end of the lifting rod is provided with a movable guide wheel which is arranged on the same plane with the guide wheels and used to prop against and tense the steel wire ropes. The device can not only singly tense the steel wire ropes, but also can reduce the wear to the steel wire ropes during tensioning, and has good use effect.
Description
Technical field
The utility model relates to a kind of steel rope Hydranlic tensioner, the slack-free steel rope Hydranlic tensioner of the divided into groups list that particularly a kind of steel cord conveyor belt vulcanizer is used.
Background technology
Traditional steel rope Hydranlic tensioner is because steel wire rope yarn footpath and interval constraint, adopt small-bore plunger oil cylinder, because plunger rod directly limits, the projection tensioning is partly for having the plate of arc groove, when tensioning, steel rope and the rigid friction of arc geosynclinal block, the coating of coup injury steel rope and distortion cause subsequent technique hidden danger; The air-proof condition of small-bore plunger oil cylinder is different big, the tensioning pressure difference that obtains, and the error of tensile force is also big; Because cylinder diameter is little, the tensile force narrow range that obtains causes the complete machine Technological adaptability to reduce.This structure at interval distributes not collinear wire-diameter steel rope for needs in same load-transfer device and tensioning is powerless.
Summary of the invention
The purpose of this utility model provides a kind of steel rope Hydranlic tensioner, and this device not only helps realizing the independent tensioning of not collinear wire-diameter steel rope, and can reduce the damage that the tensioning process produces steel rope, and result of use is good.
The purpose of this utility model is achieved in that this steel rope Hydranlic tensioner, comprise frame and horizontal one group of guide wheel that is articulated on the frame laying in order to traction tensioning steel rope, be provided with the lifting bar that is driven by tensioning hydro-cylinder between the described guide wheel, described lifting bar upper end is provided with guide wheel is in the same plane and is used to withstand and the guide wheel alive of tensioning steel rope.
Distinguishing feature of the present utility model is that tensioning hydro-cylinder adopts two-way cylinder, the cylinder head tension wheel adopts alive of U groove and improves single intensity, the technology tensile force of broad is provided, reduced the overall space size of steel rope Hydranlic tensioner, simultaneously independent tensioning hydro-cylinder is divided into groups to distinguish pressure monitor, the not collinear footpath of use becomes possibility in same load-transfer device.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Fig. 2 is the utility model embodiment hydraulic tensioning position view.
The specific embodiment
Steel rope Hydranlic tensioner of the present utility model, comprise frame 1 and horizontal one group of guide wheel 2 that is articulated on the frame 1 laying in order to traction tensioning steel rope, be provided with the lifting bar 4 that is driven by tensioning hydro-cylinder 3 between the described guide wheel 2, described lifting bar 4 upper ends are provided with guide wheel 2 is in the same plane and are used to withstand and the guide wheel alive 5 of tensioning steel rope 10.
In order to reduce the damage that the tensioning process produces not collinear wire-diameter steel rope, above-mentioned guide wheel 5 alive adapts to all rotatable, the replacing wheel bodys in processing range steel wire rope yarn footpath on the same group for wire casing.
In order to realize the independent tensioning of not collinear wire-diameter steel rope, above-mentioned frame 1 is provided with oil cylinder saddle 6, lay several locking oil cylinders 3 on the described oil cylinder saddle 6 side by side, described tensioning hydro-cylinder 3 each self-driven lifting bar provided thereon 4 work are to carry out independent tensioning to each steel rope, and described oil cylinder saddle 6 is driven by the saddle tensioning hydro-cylinder 7 of being located at frame 1 downside.
Above-mentioned tensioning hydro-cylinder 3 is the piston type double-acting oil cylinder, and rod chamber is provided with oil inlet 8 in parallel with the unified turnover oil of parallel connection, and main chamber is provided with discrete oil inlet 9 to give different control presssure turnover oil respectively.
Above-mentioned saddle tensioning hydro-cylinder 7 is the piston type double-acting oil cylinder, is beneficial to the control to 6 liftings of oil cylinder saddle.
