Description

A kind of anchor clamps that are used to lift by crane bar-shaped workpiece

Technical field

The utility model relates to a kind of anchor clamps of lifting appliance, particularly relates to a kind of anchor clamps that are used to lift by crane bar-shaped workpiece.

Background technology

In process of production, particularly in the metalworking process, sometimes need bar-shaped workpiece is moved, for heavier bar-shaped workpiece, as large-size machine the axle etc., common way is with hoist cable bar-shaped workpiece to be fixed earlier, move to the target location after with driving or other lifting appliance bar-shaped workpiece being sling again, adopt this mode very inconvenient, the bigger workpiece of some weight particularly, hoist cable will be fixed workpiece and need earlier an end of workpiece to be mentioned and could be passed workpiece to hoist cable, and, also easy generation personnel injury accident when fixation workpiece.

The utility model content

For overcoming above-mentioned defective, that the utility model aims to provide is a kind of not only convenient, but also the anchor clamps that are used to lift by crane bar-shaped workpiece of safety.

For achieving the above object, the technical solution adopted in the utility model is: a kind of anchor clamps that are used to lift by crane bar-shaped workpiece, it comprises hangs piece, two arms and two suspension hooks, two ends of described arm are respectively equipped with on the arm fixed end under the fixed end and arm, the middle part of described suspension hook is provided with the suspension hook fixed end, described suspension hook also is provided with the suspension hook head of falcate, described lower end of hanging piece is rotatably connected by fixed end on the arm and two arms, each arm is rotatably connected by fixed end under the arm and one of them suspension hook, and two suspension hooks are rotatably connected by the suspension hook fixed end.

Described one of them suspension hook is fixed with handle at the end away from the suspension hook head.

Described one of them suspension hook is fixed with the fixed form of handle and fixes or bolt for welding at the end away from the suspension hook head.

Described upper end of hanging piece is provided with lifting hole(eyelet).

Described each arm is provided with safe lockhole, is inserted with safety lock on the described safe lockhole.

When real work, only need down push handle separates the suspension hook head of two suspension hooks, then the suspension hook head is inserted the bar-shaped workpiece of required lifting, release handle again, suspension hook closes up under the effect of gravity naturally, workpiece is clamped between the suspension hook head of two suspension hooks, starts lifting appliance, can lift by crane bar-shaped workpiece.Adopted the anchor clamps that are used to lift by crane bar-shaped workpiece of the present utility model, compared, both made things convenient for, again safety with traditional approach.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1-hangs piece, 2-arm, 3-suspension hook, 4-handle, 5-workpiece, 6-suspension hook head, 7-lifting hole(eyelet), fixed end on the 8-arm, fixed end under the 9-arm, 10-suspension hook fixed end, 11-safety lockhole, 12-safety lock.

The specific embodiment

As shown in Figure 1, the utility model discloses a kind of anchor clamps that are used to lift by crane bar-shaped workpiece, it comprises hangs piece 1, two arms 2 and two suspension hooks 3, two ends of described arm 2 are respectively equipped with on the arm fixed end 9 under the fixed end 8 and arm, the middle part of described suspension hook 3 is provided with suspension hook fixed end 10, described suspension hook also is provided with the suspension hook head 6 of falcate, described lower end of hanging piece 1 is rotatably connected by fixed end on the arm 8 and two arms 2, each arm 2 is rotatably connected by fixed end under the arm 9 and one of them suspension hook 3, and two suspension hooks 3 are rotatably connected by suspension hook fixed end 10.Described one of them suspension hook 3 is fixed with handle 4 at the end away from suspension hook head 6.

Described one of them suspension hook 3 is fixed with the fixed form of handle 4 and fixes or bolt for welding at the end away from suspension hook head 6.

Described upper end of hanging piece 1 is provided with lifting hole(eyelet) 7.

When real work, lifting hole(eyelet) 7 is fixed on the lifting appliance, under the effect of gravity, arm 2 and suspension hook 3 hang naturally, and the suspension hook head 6 of two suspension hooks 3 closes up; The anchor clamps that are used to lift by crane bar-shaped workpiece of the present utility model are moved to workpiece 5 next doors that need lifting, press fixed handle 4 then downwards, because handle 4 is fixed with one of them suspension hook 3, when pressing fixed handle 4, one of them suspension hook 3 that is fixed together with handle is that rotate with handle 4 at the center with fixed end under the arm 9, whole suspension hook 3 trends towards horizontal direction, fixed end 9 along continuous straight runs outwards move under the arm, make arm 2 also trend towards horizontal direction, because hanging the lower end of piece 1 is rotatably connected by fixed end on the arm 8 and two arms 2, each arm 2 is rotatably connected by fixed end under the arm 9 and one of them suspension hook 3, two suspension hooks 3 are rotatably connected by suspension hook fixed end 10, make the suspension hook 3 that handle 4 is not installed also trend towards level, the suspension hook head 6 of two suspension hooks 3 separates; At this moment, bar-shaped workpiece 5 is placed between the suspension hook head 6 of two suspension hooks 3 release handle 4, under the effect of gravity, arm 2 and suspension hook 3 hang naturally, and the suspension hook head 6 of two suspension hooks 3 closes up, workpiece 5 is clamped between the suspension hook head 6 of two suspension hooks 3, starts lifting appliance, can be workpiece 5 liftings.

Under the weight of workpiece 5, separate the safety misadventure that causes workpiece 5 to come off and cause because of two suspension hook heads 6 during for assurance lifting workpiece 5, each arm 2 that is used to lift by crane the anchor clamps of bar-shaped workpiece of the present utility model is provided with safe lockhole 11, is inserted with safety lock 12 on the described safe lockhole 11.After between the suspension hook head 6 that workpiece 5 is clamped in two suspension hooks 3, earlier safety lock 12 is inserted in the safe lockhole 11, two arms 2 can not outwards be opened, simultaneously, also make the suspension hook head 6 of two suspension hooks 3 outwards to open, workpiece 5 can't be come off between two suspension hook heads 6, guaranteed the safety of lifting.
