Detailed description of the invention
Now by reference to the accompanying drawings the present invention is described in detail below:
The structure of detachable suspension hook group is composed as follows: upper hooks crossbeam 14 is provided with through hole B-25 totally 25, and the lower end of each through hole B-25 all forms a taper hole 24, and the height of taper hole 24 is S2, refers to Fig. 3 and Fig. 4.Ringfeder 17 upper end is provided with 4 longitudinal joints 27, and lower end is provided with boss 26, and the inside and outside of ringfeder 17 upper end is equipped with tapering, and the height of this tapering is S1, refers to Fig. 3, Fig. 5 and Fig. 6, is required to meet the condition of S1 < S2.Be equipped with tapped bore on the lower surface of upper hooks crossbeam 14 and on circle baffle plate 15, circle baffle plate 15 top is provided with through hole A-23 and counterbore 22, refers to Fig. 3 and Fig. 4.The middle part of bottom lifting beam with hook 8 is provided with through hole C-31, with anti-drop device 9 suspension hook 10 upper end through this through hole C-31 and thrust baring 6 fastening by hook nut 5.Two pieces of yoke plates 1 are set in the two ends of described upper hooks crossbeam 14 and bottom lifting beam with hook 8.
The sequence of erection of this suspension hook group is: be first arranged on suspension hook 10 by anti-drop device 9, by suspension hook 10 upper end diameter of axle via through holes C-31 through bottom lifting beam with hook 8, from up to down installs felt 7, thrust baring 6 and hook nut 5 successively afterwards.For being threaded between hook nut 5 and suspension hook 10 afterbody.Then, can bolt A-2, packing ring A-3 and locating plate 4 be passed through, the screw thread pair between hook nut 5 and suspension hook 10 is fixed.Next, by steel strand 21 from up to down through the through hole B-25 on upper hooks crossbeam 14, at taper hole 24 place, upper hooks crossbeam 14 lower end, ringfeder 17 and spring 16 are installed, then steel strand 21 corresponding to other through holes B-25, ringfeder 17 and spring 16 are installed successively.Nut A19 is arranged on the root of bolt C-18.Then bolt C-18 is passed the bolt hole on circle baffle plate 15, mounting nuts B-20.Deng circle baffle plate 15 and the distance of upper hooks crossbeam 14 lower surface adjust suitable after, locked between bolt C-18 and circle baffle plate 15 by nut A-19, by nut B-20, bolt C-18 and upper hooks crossbeam 14 are locked again, remaining bolt C-18, nut A-19 and nut B-20 are installed successively.In order to security consideration, the end of steel strand 21 needs to stretch out the certain distance in round baffle plate 15 lower surface, refers to Fig. 1, Fig. 2, Fig. 3 and Fig. 4.
Finally, two yoke plates 1 are arranged on respectively the both sides of upper hooks crossbeam 14 and bottom lifting beam with hook 8, i.e. the two ends of upper hooks crossbeam 14 and bottom lifting beam with hook 8, realize axial location respectively by bolt B-11, packing ring B-12 and axle end baffle plate 13.Yoke plate 1 and be hinged between upper hooks crossbeam 14 and bottom lifting beam with hook 8, can realize relatively rotating.
Adopt the hoisting crane of this suspension hook group to be made up of with this suspension hook group hydraulic hoisting machine 28, steel structure 29, operating unit 30, refer to Fig. 7.Wherein, hydraulic hoisting machine 28 is arranged on plane on steel structure 29, and operating unit 30 is arranged on steel structure 29 bottom, and steel strand 21 lower end of hydraulic hoisting machine 28 is fixed on the upper hooks crossbeam 14 of this suspension hook group.
The order of steel strand is unloaded in these suspension hook assembling and dismantling: first rotate upper hooks crossbeam 14, circle baffle plate 15, spring 16, ringfeder 17, bolt C18, nut A-19, nut B-20 and steel strand 21 in 90 degree around the hinge axes between yoke plate 1 and upper hooks crossbeam 14, steel strand 21 are the level of state, afterwards, unclamp nut A-19 and nut B-20, pull down bolt C-18 and circle baffle plate 15, pull down spring 16 and ringfeder 17 afterwards successively, the through hole B-25 of steel strand 21 from upper hooks crossbeam 14-is extracted out.
The principle of the invention illustrates: by bolt A-2, packing ring A-3 and locating plate 4, screw thread pair between hook nut 5 and suspension hook 10 is fixed, by thrust baring 6, realize bolt A-2, packing ring A-3, locating plate 4, hook nut 5, anti-drop device 9 and relatively rotating between suspension hook 10 and bottom lifting beam with hook 8.Be revolute pair between bottom lifting beam with hook 8 and yoke plate 1, refer to Fig. 1.Be revolute pair between upper hooks crossbeam 14 and yoke plate 1, can realize relatively rotating.Spring 16 be crushed on ringfeder 17 lower end boss 26 and circle baffle plate 15 counterbore 22 between, the conical surface of ringfeder 17 cylindrical by the guiding with upper hooks crossbeam 14 lower end taper hole 24, by steel strand 21 jam-packed.The upper end of ringfeder 17 is provided with four longitudinal joints 27, so that ringfeder 17 is by steel strand 21 jam-packed, refers to Fig. 3, Fig. 5 and Fig. 6.
In sum, the present invention, by arranging upper hooks crossbeam 14, bottom lifting beam with hook 8 two lifting beam with hook and yoke plate 1, achieves while not affecting traditional suspension hook group function, solves the installing space problem of steel strand 21; By arranging through hole B-25 and taper hole 24 on upper hooks crossbeam 14, and ringfeder 17, spring 16, circle baffle plate 15, bolt C-18, nut A-19 and nut B-20, achieve the end jam-packed of steel strand 21 and fixing.
It should be noted that, the application is not limited to the quantity of the through hole B-25 shown in Fig. 3, Fig. 4, taper hole 24, counterbore 22, through hole A-23 and corresponding steel strand 21 and spring 16.
