Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention:
as shown in fig. 1 and fig. 2, the present embodiment provides an outer embracing type lifting tool, and the outer embracing type lifting tool provided in the present embodiment cooperates with a hoisting machine to complete hoisting, and the outer embracing type lifting tool includes a supporting platform 1, a hoisting mechanism 2, a lifting claw 3, a return spring 4, a locking mechanism 5, a lifting lug 6 and a pin 7.
The supporting platform 1 is round platform-shaped, and is provided with a holding mechanism, the holding mechanism comprises at least three lifting claws 3 hinged to the outer side of the supporting platform 1 through pin shafts 7, and the three lifting claws 3 are uniformly distributed in an annular shape by taking the center of the supporting platform 1 as the center.
The lifting claw 3 comprises a supporting part 31, a clamping part 32 and a supporting hook 33 which are sequentially connected, the supporting part 31 is obliquely arranged above the supporting platform 1, the joint of the supporting part 31 and the clamping part 32 is hinged on the supporting platform 1 through a pin shaft 7, the pin shaft 7 is horizontally arranged, and the supporting hook 33 is arranged towards the vertical axis direction of the supporting platform 1; the included angle between the clamping portion 32 and the supporting portion 31 is an obtuse angle, and the supporting hook 33 is perpendicular to the clamping portion 32. The supporting part 31 is provided with a lifting lug 6 matched with the hoisting mechanism 2.
The hoisting mechanism 2 comprises a hoisting ring 21 and a plurality of chains 22, and the plurality of hoisting lugs 6 are respectively connected with the hoisting ring 21 through the chains 22. When the lifting device is used, the lifting ring 21 is matched with a lifting hook of a lifting machine, when the lifting machine lifts, the lifting lug 6 is pulled through the chain 22, so that the supporting part 31 moves towards the direction away from the supporting platform 1, the supporting part 31 drives the clamping part 32 to rotate around the pin shaft 7 as the center due to the fact that the lever is away, the lower end of the clamping part 32 drives the supporting hook 33 to move towards the vertical axis direction of the supporting platform 1, and the supporting hook 33 extends into the bottom of a vertical coil bar steel bar, so that a hanging object is supported; along with the gradual rise of whole device, hold in the palm the hook 33 and hold the thing operation of hanging, whole device receives the thing action of hanging gravity, and it is bigger to hang thing gravity, and the inward power of embracing of lifting claw 3 is bigger, and the hoist tightly holds vertical goods and transports to the assigned position. The mutual action of the force is utilized to enable the hanging object to be in closer contact with the whole device, the larger the gravity of the hanging object is, the larger the holding force of the holding mechanism is, and the safety of the device is improved.
Several all install reset spring 4 between supporting part 31 and the supporting platform 1, reset spring 4 adopts the great extension spring of coefficient of elasticity, when whole device is in unoperated state, reset spring 4 is in natural state, reset spring 4's tightening force pulling supporting part 31 removes towards supporting platform 1 direction, it uses round pin axle 7 to rotate as the center to drive clamping part 32 simultaneously, keep away from each other between clamping part 32 lower extreme, thereby make whole mechanism of holding tightly be in the state of opening, conveniently hold the mechanism cover outside waiting to hang tightly. Accomplish and hang and put the back, hoisting equipment transfers, hang subaerial rack of thing contact, whole mechanism of holding tightly does not receive and hangs thing gravity pull-down, reset spring 4 resumes natural state this moment, drive supporting part 31 simultaneously and remove towards supporting platform 1's vertical axis direction, thereby make clamping part 32 use articulated department to rotate as the axle, clamping part 32 lower extreme drives the support and colludes 33 and keep away from and hang the thing, thereby make whole mechanism of holding tightly open automatically, hold mechanism of holding tightly and hang the thing separation, realize hanging the thing and fall to the ground the back and automatically unhook, the labor is reduced, and the work efficiency is improved.
The plurality of supporting parts 31 are all provided with locking mechanisms 5, each locking mechanism 5 comprises a locking bayonet 51 and a clamping piece 52, each clamping piece 52 is arranged on each supporting part 31, and each clamping piece 52 can adopt various forms such as a clamping groove and a limiting plate, but is not limited to one form; the locking bayonet 51 is hinged on the top surface of the supporting platform 1 corresponding to the clamping piece 52, and when the locking bayonet 51 is clamped in the clamping piece 52, the holding mechanism is locked in a maximum opening state. Before the hanging object is lifted, the locking bayonet 51 is clamped into the clamping piece 52, the hanging claw 3 is limited to rotate by taking the pin shaft 7 as a center, so that the whole holding mechanism is locked in a maximum opening state, the phenomenon that when the holding mechanism is sleeved in the hanging object, the hanging claw 3 rotates by taking the hinged part as the center due to self gravity is prevented, the holding mechanism is slightly tightened, and the holding mechanism cannot be accurately sleeved outside the hanging object to influence lifting.
The utility model discloses a theory of operation: before work, firstly, manually clamping the locking bayonet 51 into the clamping piece 52, then hanging the lifting ring 21 on a lifting hook of a hoisting machine, moving the whole device to the position above an object to be hoisted, then descending the hoisting machine to drive the whole device to descend until the bottom surface of the supporting platform 1 is contacted with the top surface of the object to be hoisted, at the moment, manually controlling to separate the locking bayonet 51 from the bayonet, then starting work of the hoisting machine, pulling the lifting ring 21 to ascend, pulling the lifting lug 6 through the chain 22 to enable the supporting part 31 to move towards the direction far away from the supporting platform 1, driving the clamping part 32 to rotate by taking the pin shaft 7 as the center, driving the support hook 33 to move towards the vertical axis direction of the supporting platform 1 by the lower end of the clamping part 32, and extending the support hook 33 into the bottom of the vertical; along with whole device rises gradually, hold in the palm and collude 33 and hold in the palm the wire rod reinforcing bar, whole device receives and hangs thing action of gravity, and it is big more to hang thing gravity, and the inward power of embracing of lifting claw 3 is big more, and the hoist tightly holds vertical goods and transports to the assigned position.
After the hoisting is finished: the lifting machinery control lifting hook descends to make the individual thing of hanging of whole hoist descend, until hanging thing contact subaerial rack, whole enclasping mechanism does not receive to hang thing gravity drop-down, and reset spring 4 resumes natural state this moment, drives simultaneously and hangs claw 3 and use articulated department to rotate as the axle, and supporting part 31 removes towards supporting platform 1 direction, and clamping part 32 and hold in the palm and collude 33 and keep away from and hang the thing, thereby make whole enclasping mechanism automatic open, enclasping mechanism with hang the thing separation.
