Abstract
The utility model discloses a special lifting tool for a profile steel and a sectional material. The special lifting tool comprises a left clamping fixture, a right clamping fixture and a four-link structure, wherein the right clamping fixture is corresponding to the left clamping fixture; the upper ends of the left clamping fixture and the right clamping fixtures are bent toward the opposite direction and are connected through a lower hinge shaft; the lower hinge shaft is one of hinge shafts of a four-link structure; and two connecting links, adjacent to the lower hinge shaft, of the four-link structure, are respectively the extending rods of a left clamping fixture and a right clamping fixture. By adopting the special lifting tool for the profile steel and the sectional material, the components such as channel steels and channel girders can be lifted, the convenience is provided for clamping and disassembling, the time for lifting and disassembling is greatly saved, and the surface of the component is prevented from scratching caused by operating the tools such as steel wire ropes; simultaneously, a clamping jaw of the special lifting tool is firm, so that the risk that the tools such as the steel wire rope are shore off by the stress can be avoided, and the potential risk is prevented; and the special lifting tool for the profile steel and the sectional material is simple in structure, low in cost, convenient to use, and thus the special lifting tool is suitable for being widely popularized.
Description
Technical field
The utility model relates to a kind of suspender, relates in particular to a kind of shaped steel, section bar special hanger, belongs to the lifting device technical field of using when the large-scale material handling such as steel is installed.
Background technology
locomotive, in the manufacturing such as shipbuilding field, often need to use some large-scale channel-section steels, the parts such as trough girder, these parts also do not have special-purpose suspender at present in handling process, after being merely able to tie up with instruments such as steel ropes, hook by the handling machine catches on steel rope and comes handling again, need to waste a large amount of manpowers in the process of tying up, and in the handling process, due to stress point on steel rope, and concentrate stressed, therefore, easily exist the potential safety hazard that steel rope is cut off because stress concentrates, and steel rope is tied up not necessarily reliable, when whole stress point grasp is not good, the handling process also easily causes the swing of workpiece, if swinging excessive formation rocks and easily causes safety misadventure.In addition, steel rope is thinner, and the place is stressed larger tying up, particularly some large-scale shaped steel, section bar, and the handling process easily forms cut on workpiece, affect the quality of workpiece.
The utility model content
The purpose of this utility model is: a kind of shaped steel, section bar special hanger are provided, solve and there is no a kind of instrument that shaped steel, section bar dress hang that is specifically designed in prior art, need to come handling with the mode of steel cable, not only waste time and energy, and easily damage the technical matters of shaped steel, section bar, thereby can solve above-mentioned problems of the prior art by actv..
The purpose of this utility model is to realize by following technical proposals: a kind of shaped steel, section bar special hanger, the right clamping device and the four-bar linkage structure that comprise left clamping device, correspondence, the upper end of described left clamping device and right clamping device is crooked and be connected by lower hinge axis toward relative direction, described lower hinge axis is a wherein hinge axis of four-bar linkage structure, and in four-bar linkage structure, two connecting rods adjacent with lower hinge axis are respectively the extension rod of left clamping device and right clamping device.
As a kind of optimal way, be provided with left pawl in the lower end of described left clamping device and hook, be provided with right pawl in the lower end of described right clamping device and hook.
As further preferred, four length of connecting rod of described four-bar linkage structure are identical.
As a kind of optimal way, the hinge axis corresponding with described lower hinge axis is the upper hinge axle, and the upper hinge axle is provided be used to the link mouth that buckles.
As a kind of optimal way, the lower end of described left clamping device and right clamping device be with by corresponding vertical section of suspension hook shaped steel, profile size.
compared with prior art, the beneficial effects of the utility model: by the utility model shaped steel, the section bar special hanger comes the handling channel-section steel, the workpiece such as trough girder, clamping, convenient disassembly, saved greatly the time of suspender loading and unloading, avoided the scratching of the instruments such as use steel rope to surface of the work, simultaneously, this special hanger jaw is firm, and then the risk of having avoided the instruments such as steel rope to be cut off by stress, stopped potential safety hazard, in addition, safety for handling, swing in the time of can adopting the mode of two groups of suspenders operations simultaneously to avoid the trough girder allocation and transportation, therefore, the utility model shaped steel, the section bar special hanger is due to simple in structure, cost is low, easy to use, suit large area to popularize.
Description of drawings
Fig. 1 is the structural representation of the utility model shaped steel, section bar special hanger.
In figure: the left clamping device of 1-, the right clamping device of 2-, the left pawl of 3-hooks, and the right pawl of 4-hooks, hinge axis under 5-, the 6-four-bar linkage structure, 7-upper hinge axle, 8-link mouth, 9-is lifted workpiece, vertical section of 11-.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
Disclosed all features in this specification sheets, or the step in disclosed all methods or process, except the speciality and/or step of mutual repulsion, all can make up by any way, unless special narration all can be replaced by other equivalences or the alternative features with similar purpose, namely, unless special narration, an embodiment in a series of equivalences of each feature or similar characteristics.
As shown in Figure 1, a kind of shaped steel of the utility model, section bar special hanger comprise right clamping device 2 and the four-bar linkage structure 6 of left clamping device 1, correspondence, and left clamping device 1 and corresponding right clamping device 2 form the stone tongs that is lifted workpiece 9.The upper end of described left clamping device 1 and right clamping device 2 is crooked and be connected by lower hinge axis 5 toward relative direction, described lower hinge axis 5 is a wherein hinge axis of four-bar linkage structure 6, and in four-bar linkage structure 6, two connecting rods adjacent with lower hinge axis 5 are respectively the extension rod of left clamping device 1 and right clamping device 2.Be provided with left pawl in the lower end of described left clamping device 1 and hook 3, be provided with right pawl in the lower end of described right clamping device 2 and hook 4, to be held up by lifting workpiece 9 by this left hook 3, right hook 4, prevent from being lifted workpiece 9 owing to surely down being fallen by folder under action of gravitation; Four length of connecting rod of described four-bar linkage structure 6 are identical; The hinge axis corresponding with described lower hinge axis 5 is upper hinge axle 7, and upper hinge axle 7 is provided be used to the link mouth 8 that buckles; The lower end of described left clamping device 1 and right clamping device 2 be with by corresponding vertical section 11 of suspension hook shaped steel, profile size.
