Abstract

The utility model relates to a U-shaped anti-rotating sleeve, which comprises a sleeve body. Connectors which can rotate freely in the sleeve body are respectively installed at the two ends of the sleeve body. The U-shaped anti-rotating sleeve is characterized in that at least one of the two connectors at the two ends of the sleeve body is a U-shaped connector, a U-shaped groove is arranged on the U-shaped connector, bolt holes are formed in the two side plates of the U-shaped connector and bolts are installed in the bolt holes. The U-shaped anti-rotating sleeve has the advantages that the structure is simple, the use of a release fastener for adapting is not required during connection with other parts, and not only can the product cost be saved, but also the working efficiency is improved.

Description

U-shaped rotating prevention sleeve
Technical field
The utility model relates to a kind of parts that prevent that wire rope is hinged, be wound around, and specifically a kind of U-shaped rotating prevention sleeve, belongs to 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 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, thereby avoid wire rope, because of the increase of moment of torsion, rupture, 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 body two ends.The Placement that rotating prevention sleeve is conventional 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 is just 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 connects inconvenience, affects working efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of U-shaped rotating prevention sleeve is provided, and it is simple in structure, does not need, with shackle switching, both to have saved product cost while being connected with miscellaneous part, has improved again working efficiency.
The technological scheme providing according to the utility model: U-shaped rotating prevention sleeve, comprise body, the connecting head that can freely rotate in body is equipped with respectively at 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 further improvement of the utility model, one in two connecting heads at described body two ends is U-shaped connecting head, and another is flat connecting head.
As further improvement of the utility model, two connecting heads at described body two ends are U-shaped connecting head.
compared with prior art, advantage is the utility model:the utility model is simple in structure, does not need, with shackle switching, both to have saved product cost while being connected with miscellaneous part, has improved again working efficiency.
Accompanying drawing explanation
Fig. 1 is the structural front view of the U-shaped rotating prevention sleeve of the utility model embodiment.
Fig. 2 is the structure left view of the U-shaped rotating prevention sleeve of the utility model embodiment.
Fig. 3 is the structure plan view of the U-shaped rotating prevention sleeve of the utility model embodiment.
Fig. 4 is the three-dimensional structure diagram of the U-shaped rotating prevention sleeve of the utility model embodiment.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
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 rotating of body 1, two described 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.
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.
