Abstract
The utility model discloses a wire changing pulley. The wire changing pulley comprises an L-shaped supporting rack body. A stopping block is disposed on one end of the short arm of the L-shaped supporting rack body. A suspending circular hook is fixedly disposed on the end portion of the long arm of the L-shaped supporting rack body. One side of the suspending circular hook is fixedly connected with the end portion of the long arm of the L-shaped supporting rack body, while the other side of the suspending circular hook is connected with the long arm of the L-shaped supporting rack body through a bolt column. A suspending sleeve is formed between the suspending circular hook and the bolt column. A roller is disposed between the L-shaped supporting rack body and the stopping block and is movably connected with the long arm of the L-shaped supporting rack body through a rotating shaft and the stopping block. When the wire changing pulley is used, the suspending sleeve is sleeved on the suspending hook of a crane and is fixed by the bolt column and positioning screw nuts. And then, a wire to be used enters the pulley from a wire inlet and is placed on the roller. Therefore, wire changing operation can be performed. And thus unmanned operation of the wire changing operation is achieved and the wire changing operation is safe and reliable.
Description
Technical field:
The utility model relates to a kind of thread-changing instrument, particularly relates to a kind of thread-changing coaster that is applied on the unattended operation crane.
Background technology:
Present fast development along with economy, the increase day by day of city need for electricity amount, the original circuit of electric power system exist on the one hand diameter too small, can not satisfy existing trnamission capacity requirement, circuit is subjected to the badly damaged of various external force on the other hand, need to carry out a large amount of thread-changing work.What existing thread-changing work was generally taked is traditional thread-changing mode, exists following deficiency: 1. be provided with sealed fastener on coaster, complex structure needs manual operation during thread-changing, uses very inconvenience; 2. be subjected to the impact of crane model, hanging ladder is fixed on headstock in the mode of colligation usually; 3. time of standing on hanging ladder of operating personnel longer, easily produce tired; 4. the colligation of thread-changing coaster on the crane headstock, has potential safety hazard.
The utility model content:
Technical problem to be solved in the utility model is: a kind of safe and reliable, unattended thread-changing coaster is provided.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of thread-changing coaster, comprise supporting frame, the support frame as described above body is " L " type, galianconism one end at " L " type supporting frame is vertically installed with block, be fixedly installed in " L " type supporting frame long-armed end and hang round hook, described round hook one side and " L " type supporting frame long-armed end of hanging is fixed together, and hangs round hook opposite side by long-armed the linking together of bolt column with " L " type supporting frame, described hang to form between round hook and bolt column hang cover; Be provided with roller between described " L " type supporting frame and block, described roller is movably connected by left side rotating shaft and block, and described roller is by long-armed being movably connected of right side rotating shaft with " L " type supporting frame.
Describedly hang round hook away from the long-armed side of " L " type supporting frame, form the wire introducing port with the top end face of described block.
Described bolt column two ends are provided with positioning screw cap.
Positive beneficial effect of the present utility model is as follows:
In use, of the present utility model hanging on the hook that is enclosed within crane and by bolt column and positioning screw cap is fixed, then operate coaster, after the cable that will change is entered by the wire introducing port, be placed on the roller between " L " type bracing frame and block, can carry out corresponding thread-changing operation, so just realized just can carrying out the work of thread-changing operation under unattended operation, make the work that utilizes coaster to carry out thread-changing more safe and reliable.
The utility model has been realized the Unmanned operation of thread-changing operation, has not only saved manpower and materials, has reduced operating personnel's labour intensity, and the thread-changing process is without any potential safety hazard.
The utility model is reasonable in design, and is simple in structure, easy to operate, has very high coefficient of safety.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
referring to Fig. 1, a kind of thread-changing coaster, comprise supporting frame 5, supporting frame 5 is " L " type, galianconism one end at " L " type supporting frame 5 is vertically installed with block 1, be fixedly installed in " L " type supporting frame 5 long-armed ends and hang round hook 6, hanging round hook 6 one sides and " L " type supporting frame 5 long-armed end is fixed together, hang round hook 6 opposite sides by long-armed link together of bolt column 7 with " L " type supporting frame 5, hang to form between round hook 6 and bolt column 7 and hang cover 9, be provided with roller 2 between " L " type supporting frame 5 and block 1, roller 2 is movably connected by left side rotating shaft 3 and block 1, roller 2 is by long-armed be movably connected of right side rotating shaft 4 with " L " type supporting frame 5, wherein: describedly hang round hook 6 away from the long-armed side of " L " type supporting frame 5, form wire introducing port 10 with the top end face of block 1, be provided with positioning screw cap 8 at bolt column 7 two ends.
In use, the cover 9 of hanging of the present utility model is enclosed within on the hook of crane and is fixed by bolt column 7 and positioning screw cap 8, then operate coaster, after the cable that will change is entered by the wire introducing port, be placed on the roller 2 between " L " type bracing frame 5 and block 1, can carry out corresponding thread-changing operation, so just realize the Unmanned operation of thread-changing operation, make thread-changing work more safe and reliable.
