Abstract
The invention discloses a multifunctional crow bar which is simple in structure, convenient to use, diversified in function, material-saving and environment-friendly. The multifunctional crow bar comprises a main rod made of round steel and a function bayonet, wherein the function bayonet is fixedly arranged at the tail end of the main rod; the edge of the function bayonet is flush with the end surface of the main rod; the function bayonet is concave; one edge of the function bayonet with an opening is outward; one edge of the function bayonet opposite to the opening is welded on the main rod; and a bayonet is also arranged on the side edge, close to the outer side, in the other two side edges of the function bayonet. The multifunctional crow bar is simple in structure, convenient to use, diversified in function, low in cost, material-saving and environment-friendly.
Description
Technical field
The utility model relates to a kind of Multifunctional crow bar.
Background technology
In the structure steel fabrication process, carry out the misalignment docking of splicing, the pipe longitudinal joint counterpart of steel plate, all kinds of shaped steel turn-over, framing member assembling and proofread and correct steel plate etc., all need to use different crowbars.For the operating personnel, different crowbars has different functions, need to use different crowbars for different situations.So crowbar has a variety of, need many of preparation, need in the use ceaselessly to change.And the crowbar that has also needs to add the auxiliary block of weldering, uses hammering etc. on framing member, uses inconvenience and consumptive material large, wastes time and energy, work capacity increases.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency for above-mentioned existence, and the Multifunctional crow bar of a kind of simple in structure, easy to use, diverse in function, province's material environmental protection is provided.
The technical scheme that its technical matters that solves the utility model adopts is:
Multifunctional crow bar, it is characterized in that: include mobile jib and function bayonet socket that round steel is made, the function bayonet socket is fixedly installed on the tail end of mobile jib, its edge is concordant with the mobile jib end face, wherein, described function bayonet socket be shaped as concave shape, its one side with opening is external, one side that opening is relative is welded on the mobile jib, in other two sides of function bayonet socket, also offers bayonet socket near on the side in the outside.
In such scheme, described mobile jib adopts the round steel of φ 20 to make, and it is hammered into crooked crowbar shape with flame is roasting after red away from an end of function bayonet socket, and this end is carried out Quenching Treatment.
The utlity model has following advantage:
Simple in structure, easy to use, diverse in function, with low cost, economize the material environmental protection.

The specific embodiment
Below in conjunction with the specific embodiment, the utility model is further described:
Multifunctional crow bar as shown in Figure 1, include mobile jib 1 and function bayonet socket 2 that round steel is made, function bayonet socket 2 is fixedly installed on the tail end of mobile jib 1, its edge is concordant with mobile jib 1 end face, wherein, described function bayonet socket 2 be shaped as concave shape, its one side with opening is external, one side that opening is relative is welded on the mobile jib, in other two sides of function bayonet socket 2, also offers bayonet socket near on the side in the outside.
In the present embodiment, described mobile jib 1 adopts the round steel of φ 20 to make, and it is hammered into crooked crowbar shape with flame is roasting after red away from an end of function bayonet socket 2, and this end is carried out Quenching Treatment.
Using method and function: as shown in Figure 2, can utilize opening 3 to proofread and correct the waveform bending at thickness of slab≤8mm steel plate edge.Opening 3 is put into crooked position, a support arm of opening 3 is placed on the high point at steel plate curved edge position, another support arm with opening 3 places the steel plate back side again, and the crowbar other end of holding with a firm grip applies power (F), and namely the steel plate waveform at this position of recoverable is crooked.
As shown in Figure 3, can utilize gusset crooked on the opening 3 alignment structure spares.With an end of gusset press the spot welding of design paper size fixing after, opening 3 put into the crooked position of gusset, the crowbar other end of holding with a firm grip applies power (F), behind the crooked position straightening, the just alignment of the other end of spot welding gusset, gusset.
As shown in Figure 4, can utilize 3 groups of openings to pipe longitudinal joint misalignment interface.Opening 3 is placed the high point of pipe Stagger Edge, another support arm of opening 3 is placed the low spot of pipe Stagger Edge again, the crowbar other end of holding with a firm grip applies power (F), gets final product spot welding herein is fixing after the interface height is straight.
As shown in Figure 5, can utilize 4 pairs of all kinds of section bars of bayonet socket to carry out turn-over.Bayonet socket 4 is blocked section bar, and the crowbar other end of holding with a firm grip applies power (F), can carry out the section bar turn-over.
As shown in Figure 6, can utilize opening 3 the complex group of angle steel to the time play the effect of clamping.
As shown in Figure 7, can utilize the squareness of stiffened plate on the bayonet socket 4 adjustment structure parts.
The above, it only is the preferred embodiment of this utility model, be not that utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of the present utility model any simple modification, equivalent variations and modification that above embodiment does.
