Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, the utility model comprises main hoisting bar 6, container 4, transmission mechanism, manipulator 9, driving spring 7, on container 4 sidewalls, be arranged with manipulator spacing hole 10, described container 4 tops are provided with crossbeam 3, crossbeam 3 bottoms are provided with bearing 17, described main hoisting bar 6 upper ends are connected with lifting jockey 2, described transmission mechanism comprises a cross bar 8-1 and two montant 8-2, the middle part of described cross bar 8-1 is fixed on the lower end of main hoisting bar 6, the upper end of two montant 8-2 is hinged on respectively the two ends of cross bar 8-1, the quantity of described manipulator 9 is two, two manipulators 9 are symmetrically distributed in container 4, two manipulator 9 upper ends are hinged on respectively the lower end of two montant 8-2, expose outside container 4 through symmetrically arranged manipulator spacing hole 10 on container 4 sidewalls respectively the lower end of two manipulators 9, the quantity of described driving spring 7 is also two, and be symmetricly set in container 4, the upper end of driving spring 7 is fixed on crossbeam 3 bottoms, the lower end of driving spring 7 is fixed on the bottom of manipulator 9, the outside of described container 4 is provided with many group buffer units along the direction of improvement of container 4.
Every group of buffer unit comprises two buffer gears 11 that are symmetricly set in container 4 outsides, as shown in Figure 2, described buffer gear 11 comprises piston shoes 12, bearing pin 13, bumper bracket 14, buffering steel band 15, described bumper bracket 14 is arranged on derrick 5, on described bumper bracket 14, be vertically provided with limit track, described piston shoes 12 use bearing pins 13 are slidably arranged on limit track, described buffering steel band 15 is vertically arranged on bumper bracket 14, limit track middle part is provided with a projection 18 towards container 4, the front end of projection 18 is close to buffering steel band 15, described bumper bracket 14 is provided with the steel band adjuster 16 for regulating buffering steel band 15 rigidity.
Operation principle of the present utility model is as follows: as shown in Figure 1-Figure 3, when normal hoisting, promote jockey 2 main hoisting bar 6 is sling, transmission mechanism with on carry, driving spring 7 is in extended state, and manipulator 9 is taken in container 4, and what do not affect container 4 normally puies forward fortune. Rupture when promoting jockey 2, main hoisting bar 6 loses upper lifting force, decline with gravity, thereby driving spring 7 is because being discharged toward retraction in the energy of extended state savings before rupturing, driving mechanical hand 9 moves upward, thereby manipulator 9 propelling container 4 outer walls, enter the state of arresting, in the time that container 4 is fallen the position of buffer gear 11, manipulator 9 enters piston shoes 12, drive piston shoes 12 to move downward together, manipulator 9 is owing to being subject to piston shoes 12 active force upwards and the restriction of manipulator spacing hole 10, thereby piston shoes 12, manipulator 9, container 4 form an entirety. In entirety whereabouts motion process, piston shoes 12 move downward along bumper bracket 14, and because bearing pin 13 is subject to the restriction of bumper bracket 14 limit tracks, the motion of piston shoes 12 is divided into upward slope, straight way, descending state. Upward slope state, piston shoes 12 start extruding buffering steel band 15 from original state; Straight way state, piston shoes 12 are cushioned the plastic deformation cushion effect of steel band 15 always; Descending state, while arriving descending point, container 4 is not braked yet, and now piston shoes 12 depart from manipulator 9, and container 4 moves downward to next group buffer unit again, repeats above-mentioned steps, until container 4 is braked.
