Abstract
The invention relates to a U-shaped anti-rotation sleeve comprising a sleeve body. Connectors capable of rotating in the sleeve body optionally are mounted at two ends of the sleeve body respectively. The U-shaped anti-rotation sleeve is characterized in that at least one of the connectors at two ends of the sleeve body is a U-shaped connector, each U-shaped connector is provide with a U-shaped groove, each side plate of each U-shaped connector is provided with a bolt hole, and a bolt is fitted inside each bolt hole. The U-shaped anti-rotation sleeve is simple in structure and can be connected with other parts with no need for connecting with shackles; accordingly, product cost is saved and work efficiency is improved.
Description
Technical field
The present invention relates to a kind of parts that prevent that wire rope is hinged, be wound around, specifically a kind of U-shaped rotating prevention sleeve, belong to the hoisting and handling equipment technical field.
Background technique
Rotating prevention sleeve is usually used on some crane gears of harbour, harbour, power plant, especially be usually used in the suspension hook assembly, main purpose is to discharge the moment of torsion that wire rope in use produces, prevent hinged, the winding of wire rope, rupture because of the increase of moment of torsion thereby avoid wire rope, and can play the effect of counterweight.While being that C shape fast shackle, high-strength shackle etc. are used in combination, can guarantee to change faster Safety performance and the business efficiency of speed, the best.
Rotating prevention sleeve mainly comprises body, and the connecting head that can freely rotate in body is equipped with respectively at the body two ends.The Placement that rotating prevention sleeve is commonly used has: (1) rotating prevention sleeve+shackle+wire rope; (2) socket+shackle+rotating prevention sleeve+wire rope (or lift chain); (3) socket+shackle+rotating prevention sleeve; (4) pyriform rope sling+C shape fast shackle+rotating prevention sleeve+C shape fast shackle+pyriform rope sling; (5) rope rig+high-strength shackle+rotating prevention sleeve+high-strength shackle+socket.In above-mentioned various Placements, rotating prevention sleeve all needs joining shackle, and its reason just is that the connecting head at existing rotating prevention sleeve two ends is all flat connecting head, has so not only improved the cost of lifting part, and has connected inconvenience, affects working efficiency.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of U-shaped rotating prevention sleeve is provided, it is simple in structure, while being connected with miscellaneous part, does not need, with the shackle switching, both to have saved product cost, has improved again working efficiency.
According to technological scheme provided by the invention: U-shaped rotating prevention sleeve, comprise body, the connecting head that can freely rotate in body is equipped with respectively at the body two ends, it is characterized in that: at least one in two connecting heads at described body two ends is U-shaped connecting head, described U-shaped connecting head is provided with U-shaped groove, two side plates of U-shaped connecting head are provided with bolt hole, and bolt part is housed in bolt hole.
As a further improvement on the present invention, one in two connecting heads at described body two ends is U-shaped connecting head, and another is flat connecting head.
As a further improvement on the present invention, two connecting heads at described body two ends are U-shaped connecting head.
compared with prior art, advantage is in the present invention:the present invention is simple in structure, while being connected with miscellaneous part, does not need, with the shackle switching, both to have saved product cost, has improved again working efficiency.
The accompanying drawing explanation
The structural front view that Fig. 1 is the U-shaped rotating prevention sleeve of the embodiment of the present invention.
The structure left view that Fig. 2 is the U-shaped rotating prevention sleeve of the embodiment of the present invention.
The structure plan view that Fig. 3 is the U-shaped rotating prevention sleeve of the embodiment of the present invention.
The three-dimensional structure diagram that Fig. 4 is the U-shaped rotating prevention sleeve of the embodiment of the present invention.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: the U-shaped rotating prevention sleeve in embodiment mainly comprises body 1, be equipped with respectively at body 1 two ends can be at the interior connecting head freely rotated of body 1, described two connecting heads are U-shaped connecting head 2, described U-shaped connecting head 2 is provided with U-shaped groove 3, two side plates 4 of U-shaped connecting head 2 are provided with bolt hole, and bolt part 5 is housed in bolt hole.
The U-shaped rotating prevention sleeve can directly connect when being connected with parts such as wire rope, socket, lift chain, pyriform rope slings like this, without being connected with shackle, has both saved product cost again, has improved again working efficiency.
