Preferably, the hanging part is a lifting rod, and at least two lifting rods are fixedly arranged outside the threaded sleeve.
By adopting the design, the structure is simple, and the sling can be conveniently hung.
According to the preferable technical scheme, the locking piece is a locking nut, the locking nut is in threaded fit with the lifting main rod, and two sides of the lifting rope hanging piece are respectively provided with one locking nut.
By adopting the design, the sling hanging piece is convenient to lock and loosen.
Preferably, the other end of the lifting main rod is fixedly provided with a rotating rod.
By adopting the design, the lifting main rod is convenient to install on the die.
The hoisting assembly is characterized by comprising a hoisting cable and at least two hoisting tools;
the lifting cable comprises a main lifting cable, the lower end of the main lifting cable is connected with a hanging cable, the hanging cable corresponds to the lifting tool one to one, a hanging ring is arranged at the lower end of the hanging cable, and the hanging ring is hung on the lifting cable hanging piece.
By adopting the design, the horizontal lifting of the die can be realized by adjusting each lifting tool.
Compared with the prior art, the beneficial effects of the utility model are that: the position of the sling hanging piece on the lifting main rod is adjusted to make up the defect of fixed length of the sling, and the slings hung on the lifting main rods are positioned at the same horizontal position through the matching of a plurality of lifting tools, so that the requirement of horizontal lifting of the die is met.
Drawings
FIG. 1 is a schematic structural diagram according to a first embodiment;
fig. 2 is a schematic structural diagram of the second embodiment.
Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
Example one
As shown in fig. 1, a height-adjustable lifts by crane frock, including lifting by crane mobile jib 1 and hoist cable link spare 2, this hoist cable link spare 2 movable sleeve is established lift by crane on the mobile jib 1 still be equipped with retaining member 3 on lifting by crane the mobile jib 1, this retaining member 3 be used for with hoist cable link spare 2 is fixed lift by crane on the mobile jib 1.
Any one end of the lifting main rod 1 is a mounting end, and the mounting end is provided with external threads and is used for being connected with a lifting hole of a die.
Specifically, lift by crane mobile jib 1 and be the threaded rod, it has the screw to run through on the hoist cable link spare 2, hoist cable link spare 2 passes through the screw is installed on the threaded rod.
