Abstract
The invention relates to a dynamic compactor and a lifting hook thereof. The lifting hook of the dynamic compactor comprises two side plates, wherein a pulley assembly is arranged between the two side plates through a pulley shaft; a rope baffle is arranged at the two lateral sides and the lower side of the pulley assembly; a beam is arranged below the rope baffle; a nut is arranged at the top part of the beam; the beam is connected to a hook head; the lifting hook is characterized by having a lifting ring structure with a columnar structure integrally arranged at the top part thereof; the columnar structure penetrates through the beam and is connected to the nut; and the lifting ring structure of the hook head is connected to a detacher through a pin shaft. The hook head of the lifting hook of the dynamic compactor can reduce the hazard that the detacher damages an arm frame, and is lighter in dead-weight and simple in structure while the use requirements are satisfied; and binding treatment for the hook head is unnecessary during a transportation process.
Description
Technical field
The present invention relates to engineering machinery field, particularly relate to a kind of dynamic compaction machinery suspension hook and dynamic compaction machinery.
Background technology
Suspension hook lower end on dynamic compaction machinery connects detacher, and the other end of detacher hangs hammer ram.
As shown in Figure 1, be suspension hook 1 structural representation of current domestic use, it generally comprises: pulley assembly 2, side plate 3, pulley spindle 4, rope shelves 5, nut 6, crossbeam 7, gib head 8, screw 9 and end cap 10.Wherein, gib head 8 single hook structure that generally employing cross section is larger of suspension hook 1, and adopt the large alloy steel forging of tensile strength to form.It is generally heavier that single hook structure of gib head 8 determines its weight, and when designing suspension hook 1, strictly should control the gross weight of suspension hook 1 and the weight of gib head 8.If the gross weight of suspension hook 1 is too light, when suspension hook zero load, the frictional force suffered by wire rope is likely greater than the gross weight of suspension hook 1, and this will cause suspension hook 1 to fall; If the gross weight of suspension hook 1 lays particular stress on, then have impact on the lifting performance of dynamic compaction machinery.Therefore, when meeting instructions for use, require that the weight of the gross weight of suspension hook 1 and gib head 8 is more light better, the deadweight of gib head 8 is lighter, and its flexibility of revolution is better.
Suspension hook 1 is when transport, wiring, and put if vertical, then center of gravity is higher, easily topples over; When around wire rope, once suspension hook 1 tilts, whipline is needed to be erected.Meanwhile, due to gib head 8 single hook structure more greatly, heavier again, so in transportation, collide with other component for preventing gib head 8 from rotating, generally need gib head 8 and side plate 3 to be bundled into one, wrapping is carried out to gib head 8 and processes, therefore, the workload of conveying people is added.
The detacher of current domestic employing has two kinds of unhook modes: a kind of is that detacher breaks off relations under the effect of pull-up at unhook wire rope, referred to as pull-up detacher 11(as shown in Figure 2); Another kind is that detacher breaks off relations under the effect that unhook wire rope is drop-down, referred to as pull-down detacher 12(as shown in Figure 3).
As shown in Figure 2, when suspension hook hangs up pull-type detacher 11 1 time, the gib head 8 of suspension hook 1 connects pull-up detacher 11 by steel wire rope row 13, pull-up detacher 11 times extension hammer rams 14, one of them side plate 3 arranged outside of suspension hook 1 has a truckle group 15, and truckle group 15 upwards walked around by the unhook wire rope 16 that pull-up detacher 11 is arranged.Suspension hook hangs up pull-type detacher 11 Problems existing for 1 time: 1) in the unhook moment of pull-up detacher 11, the unhook wire rope 16 stressed time is short, and be only arranged on the outside of one of them side plate 3 due to truckle group 15, therefore easily cause suspension hook 1 and lower hanging detacher 11 to return to rock by force unbalance, this will cause the swing of dynamic compaction machinery principal arm.2) because gib head 8 freely can rotate around crossbeam 7, when hammer ram 14 rises to certain height, unhook wire rope 16 is strained, suspension hook 1 is stressed in side, pull-up detacher 11 rotates thus drives hammer ram 14 to rotate, hammer ram 14 aloft rotates, more dangerous, and unhook wire rope 16 also may be caused to be twisting together with the hoist rope of the suspension hook that hoists.3) steel wire rope row 13 bears the weight pulling force of hammer ram 14, Condition of Sudden Unloading, and steel wire rope row 13 releases energy, upwards there is no restraint, steel wire rope row 13 drives pull-up detachers 11 to rebound, and pull-up detacher 11 is easily damaged the gib head of suspension hook 1, thus damages suspension hook.4) gib head 8 size due to suspension hook 1 is larger, and unhook wire rope 16, being under relaxed state, easily hangs on the gib head 8 of suspension hook 1.
As shown in Figure 3, when suspension hook hangs pull-down detacher 12 1 time, the gib head 8 of suspension hook 1 connects pull-down detacher 12, pull-down detacher 12 times extension hammer rams 14 by steel wire rope row 13, unhook steel cable 16 oblique pull downwards of pull-down detacher 12.Pull-down detacher 12 Problems existing hung for 1 time by suspension hook: 1) steel wire rope row 13 bears the weight pulling force of hammer ram 13, Condition of Sudden Unloading, steel wire rope row 13 releases energy, steel wire rope row 13 is under the effect of the restraint of unhook wire rope 16, random releasing energy in a jumble, drive pull-down detacher 12 to swing, thus pull-down detacher 12 is damaged jib.2) unhook wire rope 16 and hammer ram 14 easily contact with each other, and mutually wear and tear, cause the damage of unhook wire rope 16.
Summary of the invention
The object of the invention is to propose a kind of dynamic compaction machinery suspension hook and dynamic compaction machinery, the gib head of its dynamic compaction machinery suspension hook can reduce detacher and to damage the harm of jib, and when meeting instructions for use, conduct oneself with dignity lighter, structure is simple, and in transportation, without the need to carrying out wrapping process to gib head.
For achieving the above object, the invention provides a kind of dynamic compaction machinery suspension hook, comprise two side plates, between two side plates, pulley spindle is provided with pulley assembly, described pulley assembly both sides and below are provided with rope shelves, crossbeam is provided with below described rope shelves, described cross rail top is provided with nut, described crossbeam connects gib head, it is characterized in that: described gib head is suspension ring structure, and its top has been wholely set a column construction, described column construction is through described crossbeam, be connected with described nut, the suspension ring structure of described gib head is connected with detacher by bearing pin.Technique scheme removes steel wire rope of the prior art row, adopts the mode that is directly connected with detacher of gib head, eliminates the energy storage of intermediate link, decreases steel wire rope and arranges detacher that storage power brings and to damage the harm of jib; The gib head of suspension hook is adopted suspension ring structure, structure is simple, easily manufactured simultaneously, and when meeting instructions for use, deadweight is lighter, can save a large amount of material costs and processing cost; And the gib head of suspension hook is arranged to suspension ring structure, in the transportation of suspension hook, also without the need to carrying out wrapping process to gib head.
