Detailed description of the invention
After reading in conjunction with the following drawings the detailed description of embodiment of the present disclosure, can understand better this realityBy novel above-mentioned feature and advantage. In the accompanying drawings, each assembly is not necessarily drawn in proportion, and has classLike the assembly of correlation properties or feature may there is identical or close Reference numeral.
The pulley-type cable-laying gear of the present embodiment is filled by the cross bar pulley cable laying that is erected at straightway crane span structureThe bend pulley cable-laying gear of putting and being erected on bend crane span structure forms, in the time of small space cable laying,Two kinds of devices are used in conjunction with, and reach and better lay effect.
Cross bar pulley cable-laying gear assembled by an axostylus axostyle 1, pulley 2, two the first supporting seats 3 andBecome, the large-diameter cable that is mainly small space is erected at the servicing unit on straight section crane span structure while laying. Fig. 1 showsGone out the work schematic diagram of cross bar pulley cable-laying gear, Fig. 2 is that the master of cross bar pulley cable-laying gear looksFigure.
Axostylus axostyle 1 selection intensity, high, the ganoid material of hardness, axle when guarantee major diameter power cable laysBar is indeformable and farthest reduce and the frictional force of pulley. The length of axostylus axostyle 1 can meet build peace engineering appointThe width of meaning specification crane span structure. Axostylus axostyle 1 two ends are installed and are prevented falling latch, in use, dismounting, transportation, increaseConvenience and prevent the first supporting seat and pulley is deviate to damage from axostylus axostyle. Axostylus axostyle 1 two ends are circular arc,Facilitate the first supporting seat 3 and pulley 2 to pass, avoid wedge angle to damage laying workman.
Fig. 3 shows the profile of pulley, and that pulley 2 is selected is lightweight, hardness and the good material of pliability. RecessedGroove can meet the size of laying of maximum cable, and R angle ensures when cable laying not by wedge angle scratch. Pulley insideLinear bearing and needle bearing are installed, have been reduced sliding friction and rolling friction on axostylus axostyle, with at utmostThe manpower of saving cable laying. Pulley two ends have installed bearing cap additional, when protection bearing, can useIn journey, isolate crane span structure, reduce the collision of pulley and crane span structure.
Fig. 4 shows the axonometric drawing of the first supporting seat. The first supporting seat 3 is selected the material that intensity is high, quality is light,Tight a bolt and be stably fixed on crane span structure by handwheel 4, have great advantage at small space. The first supporting seat3 faces that contact with cable are circular arc, avoid the scratch to cable. Axostylus axostyle gear can just regulate, and meets eachLaying of the cable of kind specification. Dish cap on axostylus axostyle gear make cross bar and the first supporting seat can unclamp fast andTighten, realize quick detach fast-assembling, quick and convenient in the time of device installation and removal. While laying, cable is elevated, convenientLay personnel's operation.
Bend pulley cable-laying gear is by the vertical pulley of a knee 6,5, second supporting seat 7Assemble, the large-diameter cable that is mainly small space is erected at the servicing unit on bend crane span structure while laying.
Knee 6 be alloy that corrosion resistant plate or specific strength are high as aluminium alloy, strength and stiffness are guaranteed. Knee connectsConnect the second supporting seat 7 and vertical pulley 5, flat segments ensures that maximum cable is at the second supporting seat 7 and vertical pulley 5Between pass. Knee 6 is movable within the scope of can 90 degree, and the cable conveniently laying is deviate from from frock.
Vertical pulley 5 adopts nylon material, and lightweight, hardness and pliability are good. Groove can be born maximum electricityLaying of cable, pulley edge R angle is large, ensures when cable laying not by scratch.
Fig. 5 shows the structure of the second supporting seat 7, and the second supporting seat 7 is selected the material that intensity is high, quality is light,Tight a bolt and be stably fixed on crane span structure by handwheel, have great advantage at narrow space. The second supporting seatThe equal circular arc of face contacting with cable, avoids the scratch to cable.
This group pulley cable-laying gear lays the path of distance at large-diameter cable, can apply as requiredIf multiple devices are set on circuit. Arrange one every 1~3 meter of crane span structure straight section, arrange at the each bend of crane span structure place1~2, on a cable run, two kinds of devices are used in conjunction with.
When cross bar pulley cable-laying gear uses, by the installation that tights a bolt of the handwheel on device two end supports seatBe fixed on the edge riser of crane span structure, Stability Analysis of Structures, takes up room little. When cabling, cable is placed onOn pulley, because the bearing between pulley and cross bar has reduced frictional force, major diameter power cable can be easily byDrag, and ensure that cable can not be scratched. After a cable run completes, unclamp on supporting seat fixingThe dish cap of cross bar, extracts cross bar out cable is put into crane span structure, then cross bar is penetrated to supporting seat crosspiece, tightens dish cap,Lay next root cable.
Bend pulley cable-laying gear, for crane span structure bend place, coordinates cross bar pulley cable-laying gear to use,Meet cable minimum bending radius, be fixed on the bend place of bend crane span structure by supporting seat, by knee 90Degree upset is placed in cable between knee and supporting seat, reduces lateral pressure and the level of cable at turning while layingPulling force, after having laid spends knee 90 upset cable is deviate from from device.
By length is greater than to 50m, the practice of laying that diameter is greater than the power cable of Φ 40mm shows, reducesOne operating efficiency semi-artificial time has improved 50%, and has reduced workman's labour intensity.
Providing previous description of the present disclosure is for making any person skilled in the art all can make or use thisOpen. To be all apparent for a person skilled in the art to various amendments of the present disclosure, and hereinDefined generic principles can be applied to other variants and can not depart from spirit or scope of the present disclosure. Thus,The disclosure is not intended to be defined to example described herein and design, but should be awarded and institute hereinThe widest scope that disclosed principle and novel features are consistent.
