Abstract
The utility model discloses a U-shaped clamp applied to construction sites. The U-shaped clamp applied to construction sites is characterized in that a U-shaped snap ring is arranged, and a threaded hole is formed at the front end of one side lever on the U-shaped snap ring; a screw rod mutually matched with the threaded hole on the U-shaped snap ring through screw threads is arranged, and the front end of the screw rod and the other side lever of the U-shaped snap ring form a workpiece clamp; a rotary handle taking the shape of the letter T is arranged at the tail end of the screw rod; and the screw rod can be rotated to be propelled in and get out of the threaded hole, so as to clamp workpieces on sites. The U-shaped clamp applied to construction sites has the advantages of simple structure, convenience in use and portability.
Description
Technical field
The utility model relates to a kind of instrument, more specifically says so in some special occasions, such as a plurality of workpiece are carried out butt welding, is used for the utensil of holding workpiece under the situation that bench vice can't use.
Background technology
In the electric power system, carry out in electric substation during grounded screen transforms, the ground connection band iron is that the welding job difficulty is quite big below the 60-70cm of ground, in the wide groove in the 20cm left and right sides.At first be that operating personnel will and have below the 60-70cm of ground in the wide groove in the 20cm left and right sides and weld, operating personnel stand in the welding of bending in the groove for a long time and can't bear, a large amount of flue dust can't leave in groove in the welding simultaneously, causes the injury to personnel's respiratory system.In addition, two ground connection band irons are when butt welding, there is not fixture to be fixed, need two Yuans operating personnel to dock in hand-held mode, weld by welding personnel again, this mode not only had a strong impact on welding quality, taken a lot of work, time-consuming, and exist actual bodily harm to the workmen, pad is poor at underground resistance to corrosion.Though bench vice is a kind of comparatively desirable fixture, bench vice can't drop in the wide groove in the following 20cm of the ground 60-70cm left and right sides and use, and simultaneously, the direction of bench vice is fixed, and can't satisfy the instructions for use of the job site of different situations.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of U-shaped mounting board that can be applicable in the job site is provided so that the operation of job site more the saving of labor, save time, laborsaving, safety.
The utility model technical solution problem adopts following technical scheme.
The design feature that the utility model can be applicable to the U-shaped anchor clamps in the job site is: " U " type snap ring is set, and the front end of the side lever on described " U " type snap ring is provided with screwed hole; The screw rod that screwed hole on setting and described " U " type snap ring cooperatively interacts with screw thread forms the workpiece clip with the bar front end of described screw rod and the opposite side bar of described " U " type snap ring; Tail end at described screw rod is the "T"-shaped rotary handle that is provided with.
The design feature that the utility model can be applicable to the U-shaped anchor clamps in the job site also is:
Between two side levers of described " U " type snap ring, the centre that is positioned at two side levers is provided with welding one lacing wire.
The front end that described screw rod is set is a conical head.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, in substation ground is installed, the ground connection ditch is conformance to standard all, the also impossible all straight lines of band iron, always have much and talk in a roundabout way, can not be all at grade during the band iron overlap joint, prior art be before welding with manual synchronizing, the utility model is directly used in two band irons are together clamped and makes it to calm down, the time that can shorten correction greatly and spent.
2, the utility model has changed needs the special messenger to locate in some scenarios in the prior art, the method for work that has the special messenger to carry out welding operation again utilizes the utility model can realize the one man operation, does not need the stranger to cooperate.
3, the utility model can utilize the U-shaped anchor clamps to implement to clamp with the active position up of script in groove to the face of land, cooperates a crossbeam again, and the operating position load is got final product on crossbeam, greatly facilitates operating process; Moreover, the temperature during owing to welding is instantaneous to reach 3000-6000 ℃, produces a large amount of hydrogen fluorine gas and flue dust, and the hard arc light radiation is arranged, the injury that the above operation in the face of land can directly avoid operating personnel may be subjected in welding process.
4, in the prior art, the artificial overlap joint between two band irons may have the slit, particularly two band irons not at grade, artificial strength is difficult to flatten, and may have rosin joint; It is seamless that the utility model can make two band irons fit tightly by reinforcing, once welds successfully, do not have rosin joint, improves the quality.
5, in the prior art, because the slit between two band irons may exist once weldering uneven or do not burn-on, weld several times, common overlap welding is three welding, and another side does not weld, and welding slag flows to the slit and can't get out, the water imbibition of welding slag is very strong, because all in the underground, joint is inner just to be in the humidity, perishable after the grounded screen welding always; Moreover plumb joint is in continuous multipass welding, and it is high more to weld temperature more, is easy to the fusing of band iron scaling loss is reduced its cross section, and zinc-plated band iron large tracts of land zinc pull-up falls; The utility model only once the welding get final product complete operation, temperature is unlikely too high, the zinc damage layer seldom, smooth welded seam, contact-making surface is tight, anti-corrosive properties are good.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model user mode schematic diagram.
Number in the figure: 1 is " U " type snap ring, 2 screw rods, 3 rotary handles, 4 lacing wires, 5 nuts, 6 workpiece.
The specific embodiment
Referring to Fig. 1, Fig. 2, in the present embodiment, " U " type snap ring 1 is set, the front end of a side lever of " U " type snap ring is provided with through hole, and the sidepiece at this place, through hole position is welded with a nut 5; The screw rod 2 that cooperatively interacts with screw thread between setting and this nut 5 is with the bar front end of screw rod 2 and the opposite side bar formation workpiece clip of " U " type snap ring; The screw terminal of screw rod tail end is removed, process the reinforcing bar of a section band radian, reinforcing bar is welded on the tail end of the screw rod 2 that removes screw terminal, form and be "T"-shaped rotary handle 3.
In concrete the enforcement, stressed excessive and rupture when the fixed clip for fear of " U " type snap ring at " U " type snap ring circular arc place, increase the intensity of the inner tensions of " U " type snap ring when clamping work pieces, between two side levers of " U " type snap ring, be positioned at middle welding one lacing wire 4 of two side levers; The displacement of workpiece 6 when preventing the screw rod rotation simultaneously is set to taper with the front end of screw rod, when rotary screw 2, makes 6 of workpiece stressed on a point.
