Background technology
We know that present is the intensity that increases reinforcing bar, often will use behind the steel bar stretching in engineering.At present, more general way is to do traction with heavy truck or caterpillar tractor, and long reinforcing bar stretches.But because long reinforcing bar, owing to the influence of self gravitation, very difficult realization is evenly stressed when stretching, thereby produces the reinforcing bar of varying strength.And this method takies bigger space, and the influence that is subjected to the geographical position sometimes also is not easy to carry out.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple to operate, easy to use, takies local few steel bar stretching device.
The technical scheme in the invention for solving the above technical problem is: a kind of steel bar stretching device, it includes and is separately fixed at ground reductor, mechanism body and fixedly steps up mechanism, reductor is connected with rectangular thread leading screw on the fixed lobe that is located at mechanism body by shaft joint, be provided with the slidingtype that matches and can slide with it thereon and step up mechanism on the rectangular thread leading screw, slidingtype steps up mechanism and fixedly steps up the two ends that mechanism clamps the reinforcing bar that will stretch respectively.
The utility model is owing to adopt reductor to drive the rotation of rectangular thread leading screw by shaft coupling, the slidingtype clamp mechanism is slided along leading screw, slidingtype clamp mechanism mobile offer folder thereon with the reinforcing bar of fixed clamp mechanism with pulling force, against existing technologies, the utility model utilizes that the flow harden theory is foundation in the mechanics of materials, integrated use the superior function of each mechanism, shirtsleeve operation and less working space are convenient to also improve when the common laborer uses operating efficiency.

The specific embodiment
A kind of as can be seen steel bar stretching device from Fig. 1 and Fig. 2, it includes and is separately fixed at ground reductor 1, mechanism body 12 and fixes to clamp mechanism 9, reductor 1 is connected with rectangular thread leading screw 5 on the fixed lobe 4 that is located at mechanism body 1 by shaft joint 2, on rectangular thread leading screw 5, be provided with the slidingtype clamp mechanism 6 that matches and can slide with it thereon, slidingtype clamp mechanism 6 and fix to clamp the two ends that mechanism 9 clamps the reinforcing bar 8 that will stretch respectively.Also be included in the Steel Ruler 10 and the travel switch 11 that are provided with between two fixed lobes 4 on the described mechanism body 12, and the thrust bearing 3 that in the close fixed lobe 4 of shaft joint 2, is provided with.
From Fig. 3 and Fig. 4 as can be seen, comprise slider body 13 in the described clamp mechanism that fixes to clamp in mechanism 9 and the slidingtype clamp mechanism 6, be located in the slider body 13 ladder type grip slide 14 and near the reversible ratchet mechanism 15 that is provided with on slider body 13 end faces of ladder type grip slide 14 than large end face.
Operation principle of the present utility model is: reductor 1 drives rectangular thread leading screw 5 by shaft coupling 2 and rotates, slidingtype clamp mechanism 6 is slided along rectangular thread leading screw 5, and slidingtype clamp mechanism 6 mobile offers folder and fixingly come the reinforcing bar 8 of tight mechanism 9 with pulling force thereon.The clamp mechanism that wherein fixes to clamp in mechanism 9 and the slidingtype clamp mechanism 6 is passed through rotation bidirectional ratchet mechanism 15, and the fixedly pretightning force of reinforcing bar 8 is provided, and makes two ladder type grip slides, 14 move toward one another owing to rubbing when stretching.Along with the continuous increase of tensile force, clamping force also constantly increases, and has guaranteed that reinforcing bar 8 clamps all the time not come off.
The slow-revving reductor 1 of rotating of can realizing of the present utility model can provide very big torque, and it links to each other with rectangular thread leading screw 5 by shaft coupling 2, uses this kind leading screw and can transmit very big power, and realizing has the conversion of reversing to stretching.Slip clamp mechanism 6 main bodys can guarantee that leading screw and slide block mesh preferably, and have adopted the clamping means of opening slot type, make things convenient for reinforcing bar 8 clampings.Fixed lobe 4 places near shaft joint 2 have used thrust bearing 3, have effectively prevented the wearing and tearing of fixed lobe 4.Displacement at the travel switch 11 control slide blocks of Steel Ruler 10 edges one side shifting can provide tensile elongation accurately.Fix to clamp mechanism 9 and can be fixed on the diverse location on ground according to the needs of stretching reinforcing bar 8 concrete length.The fixation application of reinforcing bar 8 the ladder type grip slide 14 of tape type screw thread.The frictional force that pretightning force that is provided by bidirectional ratchet mechanism 15 and bar shaped screw thread provide, two ladder type grip slides, 14 move toward one another when having guaranteed that reinforcing bar 8 stretches, and then the pressure that clamps reinforcing bar 8 is provided.And the distance of clamping reinforcing bar 8 is 10cm, thereby can better guarantee not come off when reinforcing bar 8 stretches.Travel switch 11 is fixing by gyromagnet valve control, can move freely on mechanism body 12 and is fixed in any position, is convenient to adjust distance.Set the translational speed V=22mm/s of slidingtype clamp mechanism 6, press the long reinforcing bar of percentage elongation 10% stretching 15m 8 to 16.5m as can be known, required time only is 68 seconds, has improved operating efficiency greatly so use this stretching device.When reductor 1 drives 5 transmissions of rectangular thread leading screw, consume a part of power.The main cause that causes loss has the friction of rectangular thread leading screw 5 when rotating with 6 engagements of slidingtype clamp mechanism, and the friction of 4 of rectangular thread leading screw 5 and shaft coupling 2, fixed lobes.The method that the utility model has been used thrust bearing 3, thickening slidingtype clamp mechanism 6, apply oil reduces friction, and raises the efficiency.
The part that reinforcing bar 8 two ends that the utility model brings owing to reinforcing bar 8 clampings amount to 20cm can not get stretching, if calculate by 10% percentage elongation, then every section reinforcing bar 8 20mm that stretches less so the error that causes owing to clamping is very little, can ignore.
