Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment; technical scheme in this utility model embodiment is clearly and completely described; obviously; described embodiment is only a part of embodiment of this utility model; rather than whole embodiments; based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1, the utility model discloses a kind of crane arm structure, including swing arm 1, joint arm 2, torr rope support 3, pressure rope roller 4, baffle plate 5, rope torr 6, principal arm tailing axle 7, hinge point shaft 8, sealing ring 9, shell 10, regulation cushion block 11, point pulley set 12, fixed pulley group 13 and arm point pulley 14；Described swing arm 1 one end is provided with fixed pulley group 13, and fixed pulley group 13 side is provided with arm point pulley 14；Described swing arm 1 and shell 10 junction are provided with point pulley set 12, and described shell 10 one end is provided with joint arm 2；Described joint arm 2 side is provided with the torr rope support 3 being arranged at shell 10 surface, and asks rope support 3 side to be provided with pressure rope roller 4；In the middle part of described shell 10, baffle plate 5 is installed；Described shell 10 sidewall is provided with rope torr 6, and shell 10 one end is provided with principal arm tailing axle 7；Described shell 10 is provided with hinge point shaft 8 with principal arm tailing axle 7 junction；Described shell 10 is internally provided with several sealing rings 9；Regulation cushion block 11 is installed between described joint arm 2 and joint arm 2.Described joint arm 2 is multi-segment structure, and shell 10 surface configuration has several to save arm 2；Described pressure rope roller 4 surface configuration has two bolts hole；Described principal arm tailing axle 7 is cylindrical structural, and principal arm tailing axle 7 one end arranges porose；Shell 10 sidewall is fixed in described hinge point shaft 8 one end, and hinge point shaft 8 one end is provided with bolt hole.
In use, the piston rod of middle hydraulic cylinder is hinged with basic arm by bearing pin for this utility model, and hydraulic cylinder and second section arm are by hinge, and contracting arm pulley is hinged with second section arm left end by bearing pin, and semi-girder pulley is hinged with hydraulic cylinder by bearing pin.When hydraulic cylinder stretches out relative to piston rod, second section arm is driven to stretch out；Semi-girder steel wire rope one end is connected with basic arm left end by bearing pin, walk around semi-girder pulley, the other end is connected by bearing pin and Section of three arm left end, hydraulic cylinder is during stretching out, directly drive second section arm to travel forward, be at this moment constant due to the length of semi-girder steel wire rope, cause steel wire rope upper end elongated, the other end also move therewith, therefore travelled forward by Section of three arm of semi-girder pulley driving.When hydraulic cylinder is relatively and piston rod is retracted, second section arm is driven to retract；Contracting arm steel wire rope one end is connected by bearing pin and Section of three arm left end, through contracting arm pulley, the other end is connected with basic arm right-hand member by bearing pin, during hydraulic cylinder is retracted, directly driving second section arm to retract, and contracting arm rope capacity is constant, steel wire rope lower end is elongated, the other end moves therewith, is retracted by Section of three arm of contracting arm pulley driving.
