Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of being applied to and on the various carriages carriage institute carrier is carried out the mechanically tight rope tensioning apparatus of firm binding.
Background technology
Adopt the equipment such as mechanical carriage to large-scale material (especially round tubular materials) when carrying or lifting,, all need during loading material is reinforced binding because concussion comes off to cause from carriage damages and dangerous for preventing material.Because haulage equipment need to have larger flexibility and simplicity, and institute's loaded material of wanting is of a great variety, is unsuitable for opening in the loaded down with trivial details specific binding of equipment installation putting.More existing easy methods are at carriage equivalent-load equipment manually operated ratchet to be installed to open the tight rope that assembling device is used for tensioning binding usefulness.
Be the patent of " tensioning apparatus that is used for belt or analog " such as application number 200410062101.8 patent names, a kind of tensioning apparatus is disclosed, it comprises a tensioning frame, a tensioning handle that is rotatably installed on the tensioning frame, be used for starting a belt spool that is rotatably installed in tensioning frame, reaching one drives and locking mechanism, have one and drive ratchet and a locking pawl, drive ratchet and engage with at least one ratchet, this tensioning apparatus can manually be bundled in the material binding on the carriage easier labour-saving.But because the stretching resistance that the device of such small-scale structure itself bears is limited, and the limitation of manual operation manpower size is very large, during for the larger material of binding weight, ratchet rotated to reach the limit of and can not resist the excessive inertia force that produces owing to the concussion material when both having made installation, so this tensioning apparatus can not give the admittedly firm power of tying up of material foot.
The utility model content
The purpose of this utility model be for address the above problem provide a kind of easy can with material tighter tie up automatic rope tightening tensioning apparatus on load bearing equipment.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:

As preferably, described rotation installing component comprises bearing block and is arranged at the bearing that is fixed on the rotating shaft end in the bearing block.
As preferably, described bearing block both sides are provided with the upper ear plate for installation tensioner.
As preferably, described upper ear plate and described lower ear plate are in the same plane.
Only need during installation upper lower ear plate is installed on the load bearing equipment by bolt, just can carry out work, upper lower ear plate volume is little, installs rear painstaking jail, can both install on the tiny pole, can be adapted on the various load bearing equipments applied range.
As preferably, described telescopic oil cylinder and described upper ear plate and plane, lower ear plate place are 5 ~ 20 degree angles.
Raise connecting plate oil cylinder bottom is raised, make oil cylinder and plane, upper lower ear plate place at an angle, can form trying hard to recommend of best connection angle use minimum with installation portion and move the installation portion rotation thereby reach piston rod.The oil contracting that guarantees to stretch is carried out work with maximum effect.
As preferably, described stretcher and described spoon section top are hinged; Interference is provided with elastomeric element between described spoon hinged place, section top and the stretcher.Stretcher along spoon section towards being connected in spoon section.
Buffering by elastomeric element is hinged, guarantee that stretcher can not hang over spoon section and arbitrarily rock the stable fulcrum of neither one when making manual tensioning and operate inconvenience, spoon section is rotated when driving stretcher, angle between stretcher and the spoon section can be regulated voluntarily, make spoon section pulling force maximized be used to the stretcher of pulling back, thus more laborsaving.
As preferably, be provided with one or more turning arms on the described rotating shaft.Only need to install a telescopic oil cylinder on the same load bearing equipment, just can drive all turning arms that are located on the rotating shaft during piston rod running and work thereupon.In sum, the utlity model has following beneficial effect:
1, can be effectively with more firm being bundled on the load bearing equipment of material by this device;
2, spoon head section and rotating shaft is connected, the turnability of rotating shaft, spoon section and stretcher, installation portion and piston rod, oil cylinder bottom with raise the hinged of connecting plate and guaranteed that the contractility on the piston rod can be sent to spoon section with maximum effect, make simultaneously the less contractility on the piston rod be converted into larger pulling force output;
3, the contractility of piston rod transmission efficiency in total is high, has reduced the requirement of telescopic oil cylinder and the requirement of strength of device;
4, this apparatus structure is simple, and volume is little, and is easy for installation, low to the load bearing equipment requirement, can be installed to flexibly on the various load bearing equipments, applied widely;
5, this apparatus structure is simple, and production cost is low.
