Abstract
The invention discloses a lifting balance device which comprises a lead screw and a mechanism which drives the lead screw to rotate, wherein the lead screw is connected with a lifted object; an adjusting nut is connected to the lead screw; lifting holes or lifting lugs used for lifting are formed on the adjusting nut. When a weight is lifted, the lead screw is rotated to drive the adjusting nut to move along the lead screw, the center of gravity of the weight is adjusted, and the lifting balance device is convenient to use and simple in structure, brings great convenience to construction, can be fixed on the weight for acting and also can be directly designed to be a component of the weight for use.
Description
Technical field
The present invention relates to hoisting fixture, particularly a kind of stretch-draw jack or miscellaneous equipment are lifted and need contraposition to adjust the lifting balancing device that this equipment center of gravity is installed.
Background technology
While carrying out at present stretch-draw jack to lift, conventionally just suspension ring are set on hanging object or hanger carries out lifting operation, if the center of gravity of weight is partial to while lifting, normally weight are put down, readjust lifting rope and realize the adjustment of weight center of gravity.This adjustment mode, stretch-draw jack in pre-stress construction is carried out to operation, when strand is installed, can produce the difficulty of installing, as: when jack punching axis direction and strand axis direction be not during in coaxial direction, strand is worn punching that stretch-draw jack grows to be suitable difficulty when empty and affect work efficiency, and when some jack centre hole centre is installed with instrument anchor slab and positioning plate especially, both axis of mis-aligned will be difficult to installation especially.
Summary of the invention
Object of the present invention is just to provide one can conveniently adjust weight center of gravity, the lifting balancing device of convenient construction.
Solution of the present invention is such: the mechanism that there is screw mandrel and drive screw mandrel to rotate, be connected with hanging object at described screw mandrel, and on screw mandrel, be connected with setting nut, on described setting nut, be provided with lifting hole(eyelet) or hanger for lifting.
Technical scheme also comprises more specifically: the termination that the mechanism that described drive screw mandrel rotates is screw mandrel is the structure matching with socket wrench, adopts socket wrench to drive screw mandrel to rotate.
Advantage of the present invention is in the time of lifting weight, can drive setting nut to move along screw mandrel by rotary screw, realize and adjust stretch-draw jack or miscellaneous equipment center of gravity, easy to use, bring great convenience to construction, simple in structure, can be fixed on stretch-draw jack or miscellaneous equipment and act on, a component part that also can directly be designed to stretch-draw jack or miscellaneous equipment uses.
Accompanying drawing explanation
Fig. 1 is the structural representation one of embodiments of the invention.
Fig. 2 is the structural representation two of embodiments of the invention.
In figure, 1-strand, 2-anchor plate, the 3-anchor slab of working, 4-work clip sheet, 5-limit support board, 6-coupling nut, 7-instrument anchor slab, 8-tool clamping piece, clip type jack before 9-split, 10 screw mandrels, 11-setting nut, 12-hanger, 13-permanent seat, 14-socket wrench.
The specific embodiment
As shown in Figure 2, be connected with rotating screw mandrel 10 at jack 9 use permanent seats 13, setting nut 11 is connected with screw mandrel 10, and one end of screw mandrel 10, for to be connected with socket wrench 14, is provided with hanger 12 on setting nut 11.
When the present invention uses, the strand in Fig. 11, anchor plate 2, work anchor slab 3, work clip sheet 4, stay bearing plate 5, coupling nut 6, instrument anchor slab 7, tool clamping piece 8 are connected successively; Then jack lifting is moved to while approaching coupling nut 6, if when the piston end of jack and coupling nut's 6 end is not parallel, can cause coupling nut 6 to be difficult to screw in jack piston.Now, pivotable sleeve spanner 14, the position of adjustment hanger 12, can raise piston end or reduce, and easily coupling nut 6 is screwed in to jack piston, carries out construction operation, as shown in Figure 2.
Claims (2)
