Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be further described with reference to the following specific examples, which should not be construed as limiting the invention.
As shown in fig. 1 and 2, the hoisting device provided in the embodiment of the present invention includes a hoisting frame 1, a safety fence 2, a clamping jaw 3 and two fastening screws 4, wherein the hoisting frame 1 is shaped like a Chinese character '21274', an operation area is arranged on a lower cross beam of the hoisting frame 1, the safety fence 2 is welded around the operation area, a left and a right adjustable first clamping jaw part of the clamping jaw 3 is installed on the lower cross beam of the hoisting frame 1, and the fastening screws 4 are spirally installed on the first clamping jaw part and a second clamping jaw part of the clamping jaw 3 correspondingly.
Different from the earlier patent application CN202122155328.9, which was filed by the inventor, the problems that when the 'vertical rolling mill cardan shaft hoisting device' is used, an exposed lengthened rod-shaped steel beam needs to be centered and hoisted in a balanced way when being hoisted, a traveling crane operator has poor sight and needs to be subjected to complicated cooperative command, when being installed, an operation platform needs to be erected on the basis of each vertical rolling mill, and the like, the hoisting frame 1 is optimized to be in a shape like '21274', so that when the hoisting frame is used, the hoisting frame 1 can be hoisted by the traveling crane (two lifting lugs are arranged on an upper cross beam in the hoisting frame 1 at intervals), and then a first clamping claw part is adjusted to clamp the cardan shaft to be installed by using the clamping claw 3 and then the fastening screw rod 4 is locked, with utilizing 4 secondary locking of fastening screw to wait to install the cardan shaft, finely tune the leveling in order to guarantee the balance through the chain block afterwards, the re-drive driving moves to vertical rolling mill top platform, constructor passes through in the operation area on vertical rolling mill tip platform entering hoist and mount frame 1 lower part crossbeam, driving hoist and mount cardan shaft to the mounted position afterwards, constructor carries out upper end shaft coupling fastening operation (the bolt construction of subaerial constructor completion lower extreme shaft coupling on ground) in security fence 2, constructor loosens fastening screw 4 and clamping jaw 3 in proper order after the installation, and the drive driving clamp is got and is got locking fastening screw 4, then continue to carry out the installation of next group of vertical rolling mill cardan shaft, so repeatedly until the installation is accomplished. Compared with the traditional lengthened rod type I-beam structure, the lifting device is suitable for lifting cardan shafts of various specifications, and is high in universality and stability; and the design of the fence type operation area also avoids the step of building an operation platform on the basis of each vertical rolling mill, thereby reducing the workload.
Specifically, the utility model discloses in on the mount in the first clamping jaw portion inlays and locates the lower part crossbeam in hoist and mount frame 1, and first clamping jaw portion accessible spiral install on hoist and mount frame 1 rocking wheel 5 left and right adjustable install on hoist and mount frame 1 in the lower part crossbeam, the utility model discloses in for the installation that adapts to different specification universal shafts, therefore the selective use rocking wheel 5 drives first clamping jaw portion, can be through 3 apertures of rotatory rocking wheel 5 control clamping jaw like this to adapt to the needs (corresponding) of snatching of different specification universal shafts, the utility model discloses in also can install the lead screw motor in the operation area), in order to pass through the first clamping jaw portion of lead screw motor drive. For avoiding damaging the cardan shaft, the utility model discloses the inboard of well clamping jaw 3 is equipped with the one deck rubber.
The utility model discloses the difference in height of upper portion crossbeam and lower part crossbeam is greater than the height of gear box in the vertical rolling mill in well hoist and mount frame 1 to hide the vertical rolling mill gear box when hoist and mount, installation cardan shaft.
The utility model discloses in for the driving operator observes, operates, can be in order to paint the good scale ring of sign on 1 upper portion crossbeam of hoist and mount frame, can show when this scale ring and rolling mill gear box edge coincidence that the cardan shaft just in time aligns with the gear box axle center, erection joint spare can be smoothly. Actual hoisting shows that the hoisting frame 1 with the '21274', namely a structure like a Chinese character '\' is more convenient for hoisting and using by a crane operator relative to a lengthened rod-shaped steel I-beam (an upper beam is closer to a crane, so that the observation is facilitated).
The above are only preferred embodiments of the present invention, and not intended to limit the scope and the embodiments of the present invention, and it should be appreciated by those skilled in the art that the equivalent alternatives and obvious modifications made in the present invention should be included within the scope of the present invention.
