Abstract

The utility model relates to a hanger for pretreating wire rods, and particularly, the hanger is applied in the manufacturing process of the pretreatment of wire rods of prestressed steel strands. The hanger comprises a travelling crane (2), a rotary hook (3), a sulky derrick (4), a wire-hanging bracket (5) and a fixed chain (6), wherein, the wire-hanging bracket (5) is hung on the travelling crane (2) through the sulky derrick (4) and the rotary hook (3). The utility model is characterized in that one end of a cross rod below the wire-hanging bracket (5) is fixedly connected with one end of the wire-hanging bracket (5) through a bayonet (1), and the other end of the cross rod is connected with the other end of the wire-hanging bracket (5) through the fixed chain (6). The hanger can avoid the wire rod from rotating in the pretreatment process, so that the wire rod can keep stable, and the safety performance and the operability are improved.

Description

Pretreatment wire rod suspender

(1) technical field

The utility model relates to a kind of pretreatment wire rod suspender.Specifically be applied to prestress wire pretreatment wire rod production process.Belong to metalwork production facilities technical field.

(2) background technology

Prestress wire is formed by seven steel wires twisted under the high speed revolution of wire twisting machine, and using steel wire is that drawing forms through draw bench by the wire rod behind the pretreating process (raw material).Under certain technological condition, wire rod obtains the finish coat that subsequent production needs through pretreatment.In preprocessing process,, must use suitable suspender for ease of the lifting of wire rod.Present wire rod hanger structure sketch is seen Fig. 1.The summary of this wire rod suspender principle: the pretreatment wire rod with suspender mainly by surface bearing 7, driving 2, shackle hook 3, sulky derrick 4, hang spring frame 5 and fixedly 6 six parts of chain form.Its surface bearing 7 is rotationally connected with hang spring frame 5.When preprocessing process, adjust hang spring frame 5 directions by rotational plane bearing 7, wire rod is placed on the hang spring frame 5 following cross bars, after fixedly chain 6 is fixed, lift by crane then by driving 2, adjust directions to adapt to production procedure by shackle hook 3 then.

As seen from Figure 1, wire rod of every production all will be adjusted direction by surface bearing 7 and 3 two parts rotations of shackle hook, though easy to operate, can adapt to production requirement, because cross bar rotates flexibly below the hang spring frame 5, and heavier, the cross bar rotation appears easily.Therefore have potential safety hazard, and if fixedly chain 6 fractures in process of production because wire rod is heavier, cause that the cross bar rotation causes safety misadventure.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of easy and simple to handle, and can keep wire rod wire rod in lifting and production process the pretreatment wire rod suspender that rotates steadily, not occur.

The purpose of this utility model is achieved in that a kind of pretreatment wire rod suspender, comprise driving, shackle hook, sulky derrick, hang spring frame and fixing chain, described hang spring frame is lifted in the driving by sulky derrick and shackle hook, one end of the cross bar below the described hang spring frame is captiveed joint with an end of this hang spring frame by bayonet socket, and the other end of described cross bar links to each other with the other end of hang spring frame by fixing chain.

The utility model only need pass through the shackle hook unitary rotation at the lifting and the treating process hang spring frame of wire rod, has avoided that pole rotates operation inconvenience and the security risk of bringing below the hang spring frame.

The utility model pretreatment wire rod is easy and simple to handle with suspender, and can satisfy: suspender keeps wire rod wire rod in lifting and production process steady, rotation do not occur, thereby has reduced potential safety hazard, and improved work efficiency.

(5) specific embodiment

Referring to Fig. 2, the pretreatment wire rod suspender that the utility model relates to, mainly by driving 2, shackle hook 3, sulky derrick 4, hang spring frame 5 and fixedly chain 6 form.Described hang spring frame 5 is lifted in the driving 2 by sulky derrick 4 and shackle hook 3, one end of the cross bar below this hang spring frame 5 is captiveed joint with an end of this hang spring frame 5 by bayonet socket 1, and the other end of the cross bar below this hang spring frame 5 passes through fixedly that chain 6 links to each other with the other end of hang spring frame 5.

Claims (1)

1, a kind of pretreatment wire rod suspender, comprise driving (2), shackle hook (3), sulky derrick (4), hang spring frame (5) and fixing chain (6), described hang spring frame (5) is lifted in the driving (2) by sulky derrick (4) and shackle hook (3), an end that it is characterized in that the cross bar below the described hang spring frame (5) is captiveed joint with an end of this hang spring frame (5) by bayonet socket (1), and the other end of described cross bar passes through fixedly that chain (6) links to each other with the other end of hang spring frame (5).
