The bottom of the boom 20 is vertically provided with a lifting cross arm 24, and cargo (not shown in the figure) can be lifted through the lifting cross arm 24. The cargo may be concrete cargo, cargo box, etc., and is not particularly limited herein.
The hanger includes a rectangular hanger frame 41, the number of the hanger rods 20 is four, and the tops of the four hanger rods 20 are connected to four corners of the hanger frame 41, respectively. Specifically, the four corners of the hanger frame 41 are respectively provided with connecting grooves, the top of the hanger rod 20 is provided with a connecting protrusion 25, and the connecting protrusion 25 is rotatably fitted in the connecting grooves.
In this embodiment, in the four suspension rods 20, the trapezoidal thread sections 21 on the two suspension rods 20 located on the same side are arranged in a left-handed manner, and the trapezoidal thread sections 21 on the two suspension rods 20 located on the other same side are arranged in a right-handed manner.
A plurality of hanger reinforcing ribs 42 are arranged in the hanger frame 41, so that the hanger structure is stable and reliable, and the bearing strength is high.
The nut frame comprises a rectangular nut frame 32, the number of the split nuts 31 is four, and the four split nuts 31 are respectively fixed at four corners of the nut frame 32; the trapezoidal thread sections 21 on the four suspension rods 20 are respectively connected with four split nuts 31. In this embodiment, as shown in fig. 4 and 5, two connecting plates 33 are fixed on the split nut 31, extension lines of the two connecting plates 33 are perpendicular to each other, and the two connecting plates 33 are respectively fixed on the nut frame 32 through bolt connections, so that the split nut 31 can be fixed on the nut frame, and the nut frame can drive the split nut 31 to move up and down in the process of moving up and down.
The nut frame 32 is provided with a plurality of nut frame reinforcing ribs 34, so that the nut frame structure is stable and reliable, and the bearing strength is high.
The installation process of the hoisting device capable of automatically unhooking of the embodiment comprises the following steps: the four split nuts 31 are respectively matched with the trapezoidal thread sections 21 on the four suspension rods 20 in place and the bolts are tightened, and the split nuts 31 slide down to the top of the lower limit plate 23. Hoisting the hanger through the main hook 11, hoisting the four hanger rods 20 through the auxiliary hooks 12, plugging the connecting bulges 25 at the tops of the hanger rods 20 into connecting grooves of the hanger, and then sealing the hanger through channel steel and bolts; four booms 20 are thus connected to the spreader, and the lifting cross-arm 24 at the bottom of the booms 20 remains horizontal. After the four hanger rods 20 are installed and adjusted in position, the nut frame is lifted by the auxiliary hook 12, and the four split nuts 31 are connected to four corners of the nut frame respectively to form the whole lifting device.
The adjustment process of the hoisting device capable of automatically unhooking in the embodiment comprises the following steps: after the hanger device is installed, the nut holder can be slowly lifted by the auxiliary hook 12, the rotation of the boom 20 is observed, the position of the split nut 31 is maintained until the boom 20 rotates 90 degrees, and the upper limit stop 22 is adjusted to be in contact with the split nut 31. Then the auxiliary hook 12 is released, the nut frame is made to fall under the action of the self-weight, and the rotation of the hanger rod 20 is observed. If the nut bracket's own weight is insufficient to rotate the hanger bar 20, appropriate weights can be added to the nut bracket to ensure that the hanger bar 20 is free to rotate as the nut bracket falls.
The hoisting process of the hoisting device capable of automatically unhooking of the embodiment comprises the following steps: after the adjustment of the lifting appliance device is completed, the auxiliary hook 12 is loosened, the main hook 11 is started to lift the whole lifting appliance device, the four suspension rods 20 are aligned to the reserved suspension holes of the goods, and the lifting cross arm 24 slowly falls into the goods horse leg box. When observing that the lifting cross arm 24 falls into the horse leg box, a lifting commander gives an instruction to operate the auxiliary hook 12 to lift the lifting nut frame, so that the split nut 31 rises and is in contact with the upper limit baffle 23, and the suspender 20 rotates by just 90 degrees at the moment. Then slowly lifting the main hook 11, simultaneously keeping the auxiliary hook 12 tensioned, and reacting on a tensioner of the main hook 11 after the lifting cross arms 24 of the four suspension rods 20 contact and are tightly jacked with the cargo horse leg box; the secondary hook 12 is now released and the nut carrier will remain stationary due to the friction of the boom 20 with the cargo. Slowly hoisting the goods, after the goods takes one's place according to the construction plan, start main hook 11 and transfer whole hoist device, after lifting by crane cross arm 24 no longer with the contact jack-up of goods horse leg box, nut frame can fall down lower limit baffle 23 automatically, jib 20 has rotated 90 this moment, rethread auxiliary hook 12 lifts by crane nut frame, main hook 11 and lifts by crane the gallows rebound this moment, four jibs 20 can be taken out from horse leg box smoothly, then continue to accomplish the hoist and mount of next goods.
The goods have different weights and sizes, and can be adjusted according to the size of the goods and also can be used in a compatible way as much as possible.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the following embodiments, it will be apparent to those skilled in the art that the present invention may be modified or equivalents may be substituted for some of the features of the embodiments described below; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
