Through the arrangement of yoke plates and two hanging hook cross beams including an upper hanging hook cross beam and a lower hanging hook cross beam, the functions of the traditional hanging hook group are not influenced, and meanwhile, the solution of steel stranded wire installation space problem is realized. By a method of forming through holes and cone holes in the upper hanging hook cross beam and adopting expansion sleeves, springs, round baffle plates and screw bolts for fixation, the end extrusion and fixation of a steel stranded wire are realized. A crane adopting the dismountable hanging hook group is characterized in that the hydraulic lifting machine is arranged on the upper plane of a steel structure, an operation mechanism is arranged at the lower part of the steel structure, and the lower end of the steel stranded wire of the hydraulic lifting machine is fixedly arranged at the bottom of the upper hanging hook cross beam of the hanging hook group. The dismountable hanging hook group provided by the invention perfectly solves the technical problems that the traditional hanging hook group cannot realize reliable connection with the steel stranded wire, and fast dismounting is difficult to realize. The dismountable hanging hook group and the crane have the advantages that the structure is simple, the safety performance is high, the manufacturing, the mounting, the dismounting and the maintenance are respectively convenient, the weight of the whole machine is reduced, and the manufacturing cost is reduced.

Description

The detachable suspension hook group that a kind of hydraulic hoisting machine is used and with the hoisting crane of this suspension hook group
Technical field
This device relates to handling machinery industry, is specially adapted to have the large hydraulic gig suspension hook group of quick release requirement.
Background technology
Traditional hoisting crane, the winch being conventionally comprised of parts such as electrical motor, coupler, drg, retarder and reel groups, and steel rope and suspension hook group, form lifting mechanism jointly, realizes the handling to load.The shortcomings such as it is many that the hoisting crane of this form has constituent elements, and fault rate is relatively many, and complete machine weight is heavier, are not suitable for frequency of operation lower, and the larger operating mode of hoisting capacity.
Large hydraulic gig by fluid control, can be realized the handling of load by gig and steel strand, can solve conventional hoist in theory lower in frequency, and the job requirement of the hoisting capacity operating mode of having relatively high expectations.But if large hydraulic gig is applied on crane facility, the suspension hook group that the parts such as traditional assembly pulley and suspension hook form cannot realize and being connected with steel strand failure-free, is difficult to meet the demand of quick-detachment.
Lower for frequency of operation, and the operating mode that hoisting capacity is had relatively high expectations, adopt the conventional hoist of winch form no longer applicable, adopt hydraulic hoisting machine to drive suspension hook group to realize load handling and be more suitable for this operating mode, the steel strand that existing traditional suspension hook group cannot be used with hydraulic hoisting machine are realized and being reliably connected, and are difficult to meet the requirement of quick-detachment.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes following technical scheme: the detachable suspension hook group that a kind of hydraulic hoisting machine is used, it possesses following characteristics: upper hooks crossbeam is provided with the through hole B distributing symmetrically, and the lower end of this through hole B forms taper hole, and the height of this taper hole is S2.Be provided with round baffle plate, the aperture of the through hole A on this circle baffle plate, quantity is consistent with position and described through hole B and by bolt C, nut A and nut B, be fixed on the bottom of described upper hooks crossbeam.On circle baffle plate, be also provided with counterbore.Steel strand via through holes B, through hole A stretch out round baffle plate downwards.Between counterbore and taper hole, cover has spring and ringfeder from bottom to top, and ringfeder is equipped with tapering inside and outside top, and the height of tapering is S1, and this height S1 is less than the height S2 of aforementioned taper hole.Ringfeder bottom is also provided with boss, and the external diameter of boss is less than the internal diameter of spring.Ringfeder is provided with at least twice longitudinal joint, and the longitudinal joint in the present embodiment is uniform 4.The middle part of bottom lifting beam with hook is provided with through hole C, fastening by hook nut through this through hole C and thrust baring with the suspension hook upper end of anti-drop device.Two yoke plates are set in the two ends of upper hooks crossbeam and bottom lifting beam with hook.Bolt B, packing ring B, the axle end baffle plate for axle head that stretch out at yoke plate and upper hooks crossbeam and lifting beam with hook two ends, bottom are fixed.The afterbody of suspension hook is also provided with bolt A, packing ring A and locating plate.
A kind of hoisting crane that adopts the detachable suspension hook group that hydraulic hoisting machine claimed in claim 1 uses, its feature is: hydraulic hoisting machine is arranged on plane on steel structure, operating unit is arranged on described steel structure bottom, and the lower end of the steel strand of hydraulic hoisting machine is fixed on the upper hooks crossbeam bottom of this suspension hook group.
