Abstract
The utility model discloses an anti-jamming line stringing device which comprises a frame, a baffle, two protection spring sheets with the same structure and a pulley. The protection spring sheets are symmetrically fixed on the inner side of the frame. The lower ends of the protection spring sheets are located in a groove on the side of the pulley. The side of the pulley is matched with the lower ends of the protection spring sheets in shape. The pulley is fixed on the frame through a horizontal shaft. The baffle is shaped like an inverted L. One side of the baffle is fixed on the top end of the frame through a pressure lever. According to the utility model, the anti-jamming line stringing device has the advantages of simple structure and low manufacturing cost; when the anti-jamming line stringing device is used to spread a steel cable, however the steel cable jumps, the steel cable falls into the groove of the pulley along the protection spring sheets; after the protection spring sheets are added on the pulley, the condition that a line is jammed between the pulley and the frame is avoided; manpower and material resources are greatly saved; and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of wire clamping prevention wire-binding device.
Background technology
Adopt when carrying out wire erection in electric power system and first put the mode that steel wire rope (4#) takes out line with retractable line car and construct, common pulley is when putting steel wire rope, the accident of ply-yarn drill between pulley and framework easily occurs, especially in long circuit is taken out line process, wire line shoe can cause project progress to be stagnated in pulley, must process, if find that untimely meeting causes the damage of steel wire rope or wire, also can cause shaft tower to tilt, seriously influence construction schedule, and band is served unnecessary man power and material's waste.
In order to solve wire line shoe in the problem of pulley flanks, can change existing stringing pulley, but existing stringing pulley still can use, and changes merely pulley and will cause great waste, if therefore can transform to realize that the wire clamping prevention function becomes very important to existing stringing pulley.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of wire clamping prevention wire-binding device, simple in structure, cost of manufacture is low, when using the utility model wire clamping prevention wire-binding device unfolding steel wire rope, how steel wire rope is beated and all can be fallen in the groove of pulley along the protection shell fragment, install the pulley of protection after shell fragment additional the situation of ply-yarn drill between pulley and framework can not occur, save greatly human and material resources, improved operating efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of wire clamping prevention wire-binding device comprises framework, catch, two protection shell fragment and pulleys that structure is identical; Protection shell fragment symmetry be fixed in the framework medial surface, protection shell fragment lower end is positioned at the groove of pulley, the pulley groove shapes is coincide with protection shell fragment lower end;
Pulley is fixed on framework by transverse axis;
Catch is inverted L-shaped, and catch on one side is fixed in the framework top by pressure lever.
Each protection shell fragment is fixed in the framework medial surface by two screws.
Preferred framework, protection shell fragment and catch are that metal is made.
The framework lower end is provided with U-shaped draw-in groove, and draw-in groove is provided with at least two fixing holes.
The beneficial effect that adopts technique scheme to produce is: the utility model wire clamping prevention wire-binding device is simple in structure, cost of manufacture is low, when using the utility model wire clamping prevention wire-binding device unfolding steel wire rope, how steel wire rope is beated and all can be fallen in the groove of pulley along the protection shell fragment, install the pulley of protection after shell fragment additional the situation of ply-yarn drill between pulley and framework can not occur, save greatly human and material resources, improved operating efficiency.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is left view of the present utility model;
1 is framework, and 2 is catch, and 3 are the protection shell fragment, and 4 is pulley, and 5 is transverse axis, and 6 is pressure lever, and 7 is U-shaped draw-in groove.
Embodiment
The wire clamping prevention wire-binding device comprises framework 1, catch 2, two protection shell fragment 3 and pulleys 4 that structure is identical; Protection shell fragment 3 symmetries be fixed in framework 1 medial surface, protection shell fragment 3 lower ends are positioned at the groove of pulley 4, pulley 4 groove shapes are coincide with protection shell fragment 3 lower ends;
Pulley 4 is fixed on framework 1 by transverse axis 5;
Catch 2 is inverted L-shaped, and catch 2 is fixed in framework 1 top by pressure lever 6 on one side.
Each protection shell fragment is fixed in the framework medial surface by two screws.
Framework 1, protection shell fragment 3 and catch 2 are made for metal.
The framework lower end is provided with U-shaped draw-in groove 7, and draw-in groove 7 is provided with at least two fixing holes, and draw-in groove is used for the utility model wire-binding device is stuck in crossbeam.
Have spring on pressure lever, when pressing catch downwards and be positioned at one side directly over pulley, open a gap between catch and framework line is passed through.Can also groove be set to place catch in framework one side that catch is installed as distortion of the present utility model.
Press catch when the utility model uses downwards and be positioned at one side directly over pulley, open a gap between catch and framework this moment, by the gap, line put in the groove of pulley, in any case pull wire, wire can not skid off in groove, can not be stuck between framework and pulley yet.
The utility model wire clamping prevention wire-binding device can be the transformation to existing stringing pulley, installing the protection shell fragment in existing pulley groove additional gets final product, reequip easy, easy row, cost is low, can reduce greatly in application the construction human and material resources waste, effectively increase work efficiency.
The utility model has effectively solved the problem of card line, minimizing every basic shaft tower in the unwrapping wire process all will someone be guarded greatly, fixes a breakdown at any time, has reduced the input of manpower, can avoid again the card line to the damage of wire and the inclination of shaft tower, operating efficiency improves greatly.
