Description
Technical field
The utility model relates to a kind of shifting apparatus of material, particularly relates to a kind of shifting apparatus for bar.
Background technology
In workshop, due to need of production, often needing with crane, material to be moved, because weight of material is large, there is very large danger when carrying, all can cause many safety misadventures because of lifting is improper every year, the serious harm personal safety of people.General device is all provided with the structure for wire rope handling rope such as hanger, convenient mobile; But the bar that the bar, particularly cross section of often wanting transfer shaft-like in workshop are rounded, not easily fixes during transfer, easily comes off and roll, easily safety misadventure occurs.The transfer of current bar is generally use steel rope binding bar, but use steel rope to have following shortcoming: one, steel rope will around bar one week, if very close to each other between bar and bearing surface, need to lift bar so that steel rope passes bottom bar, bundle difficulty, waste time and energy; When placing bar, the problem that steel rope takes out difficulty can be run into equally, have impact on work efficiency; Two, bar not easily binds by steel rope, and the easy landing of bar, if landing not only can damage bar, and can cause casualties.
Summary of the invention
The utility model is intended to solve above-mentioned mentioned technical matters, provides a kind of convenient operation, time saving and energy saving, safe and efficient and robust bar shifting apparatus.
The utility model is realized by following technical scheme:
A kind of bar shifting apparatus, comprise rotating shaft, carry out the first hinged jig arm and the second jig arm by rotating shaft, first jig arm and the top of the second jig arm are provided with the hoist cable mounting hole carrying out with hoist cable being connected, the bottom of the first jig arm and the second jig arm is respectively arranged with the first holding part and second holding part of clamping bar, first holding part and the second holding part all abut against with the radially outer edge of bar, and the radius of curvature of the first holding part is greater than the radius of curvature of the second holding part.
Further, extension spring is connected with between the top of described first jig arm and the second holding part.
Further, described second holding part is installed with the handle arranged perpendicular to the second jig arm.
Further, described first jig arm and the second jig arm are provided with the rotating shaft mounting hole that at least two regulate the length of the first holding part and the second holding part.
Further, the radius of curvature of described first holding part is greater than the radius of bar, and the radius of curvature of the second holding part is less than the radius of bar.
Further, wedge shape is all arranged in the end of described first holding part and the second holding part.
Further, described first jig arm, the second jig arm are all installed with brace panel.
Beneficial effect is: bar shifting apparatus of the present utility model has the following advantages: one, bar shifting apparatus clamps bar by recess, can carry out clamping lifting without the need to lifting bar to bar; When placing bar, the radius of curvature of the first holding part is greater than the radius of curvature of the second holding part, thus the first holding part is relatively easily taken out from the bar heap be stacked in together; Two, use extension spring to carry out power-assisted when bar shifting apparatus opens, the holding part of the second jig arm is also installed with the handle regulated for human assistance, time saving and energy saving when making clamping; Three, the first jig arm, the second jig arm are provided with adapter plate, it is more firm that adapter plate makes a clamp arm be connected with the second jig arm, extends the service life of bar shifting apparatus and prevent bar from coming off from bar shifting apparatus.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is the schematic diagram of a kind of bar shifting apparatus in the utility model.
Detailed description of the invention
A kind of bar shifting apparatus as shown in Figure 1, comprise rotating shaft 1, carry out the first hinged jig arm 2 and the second jig arm 3 by rotating shaft 1, first jig arm 2 and the top of the second jig arm 3 are provided with the hoist cable mounting hole carrying out with hoist cable being connected, the bottom of the first jig arm 2 and the second jig arm 3 is respectively arranged with the first holding part 22 and the second holding part 32 of clamping bar 10, first holding part 22 and the second holding part 32 all abut against with the radially outer edge of bar 10, and the radius of curvature of the first holding part 22 is greater than the radius of curvature of the second holding part 32.
Because the first jig arm 2 and the second jig arm 3 have used lever principle, the weight of the Clamping force and bar 10 self that the first holding part 22 and the second holding part 32 put on bar 10 is directly proportional, so no matter bar 10 weight size, clamping bar 10 is without the need to using extra power-assisted; When putting down bar 10, the radius of curvature of the first holding part 22 is greater than the radius of curvature of the second holding part 32, and arrange closely in bar heap even if bar 10 is deposited in, the first holding part 22 is also extracted easy crack between bar 10.
Extension spring 4 is connected with between the top of described first jig arm 2 and the second holding part 32.Extension spring 4 makes bar shifting apparatus stay open state, during use, the first holding part 22 and the second holding part 32 is abutted with bar 10.
Described second holding part 32 is installed with the handle 5 arranged perpendicular to the second jig arm 3.Bar shifting apparatus is in clamping and moving process, and handle 5 plays the effect of righting bar 10; During clamping, the first holding part 22 of bar shifting apparatus and the second holding part 32 abut with bar 10 by operating handle 5, simultaneously pressing handle 5, and under the effect of lifting pulling force, bar 10 clamps by the first holding part 22 and the second holding part 32.
Described first jig arm 2 and the second jig arm 3 are provided with the rotating shaft mounting hole that at least two regulate the length of the first holding part 22 and the second holding part 32.According to the diameter of bar 10, by regulating the position of rotating shaft 1 in the first jig arm 2 and the second jig arm 3, the length of the first holding part 22 and the second holding part 32 can be regulated, thus regulate the aperture of the first jig arm 2 and the second jig arm 3, meet operating needs.
The radius of curvature of described first holding part 22 is greater than the radius of bar 10, and the radius of curvature of the second holding part 32 is less than the radius of bar 10, and like this, when placing bar 10, the first holding part 22 is easily extracted from the gap between bar 10.
Be easier to make bar shifting apparatus clamp bar 10, wedge shape is all arranged in the end of the first holding part and the second holding part, and when clamping bar 10, the end of the first holding part 22 and the second holding part 32 can be inserted into the bottom of bar 10 easily.
Described first jig arm 2, second jig arm 3 is all installed with brace panel 6.Brace panel 6 except make bar shifting apparatus structure more firmly except, more steady when also making mutually to rotate between the first jig arm 2 and the second jig arm 3.
Certainly, when using bar shifting apparatus lifting bar 10, for making bar 10 move more reposefully, two covers or two can be used to overlap above bar shifting apparatus simultaneously.
The direction of the outside lifting appliance pulling force suffered by hoist cable of direction shown in arrow in Fig. 1.
Above embodiment is only not limited in order to the technical solution of the utility model to be described, all do not depart from the utility model spirit and scope any amendment or equivalently to replace, it all should be encompassed in the scope of technical solutions of the utility model.
