Description

A kind of cable unwinding device

Technical field

The utility model relates to building intelligent system engineering light current cable and lays field, particularly a kind of cable unwinding device.

Background technology

In the key pipeline network construction of existing general building light current, need to lay a large amount of all kinds of cables, the general 200 meters of left and right of this class cable one dish, roughly adopt two kinds of laying methods: a kind of is to utilize jack stand, first cable traverse, with seamless steel pipe, be transverse on cable hank, then with jack stand, prop up, manually drag again, draw, shoulder and carry out cable laying, in laying large-sized cable process, jack stand is easy to outwell, and another kind is directly to utilize crane, crane is directly sling cable, more manually lays.These two kinds of methods draw cable hank to lay by manpower substantially, and a people once can only be put a dish, inefficiency, and need to overturn back and forth, otherwise cable can be because be named more and more distortion of strength, and even disorder, runs out of space, and potential safety hazard is also a lot.

Chinese patent notification number: CN2143378, the day for announcing: 1993.10.06, name is called the patent documentation of " Cable holder for distribution " and has introduced a kind of Cable holder for distribution, comprises two supporting guide upright posts, a tray, a jack; One base, one coordinates and is arranged on the lifting stirrup between two column side levers movably; Lifting stirrup inner side is provided with multipair supporting shoulder, and tray two ends are releasably shelved on arbitrary upper to supporting shoulder, and jack is under lifting stirrup between fixed lever and base.This Cable holder for distribution can be convenient and strength-savingly for the on-the-spot supporting cable draw drum of cable construction unwrapping wire.But, the line-putting method that this utility model adopts remains and adopts the bracing frame at two ends to support, paying out drum remains and is erected between two bracing frames, to the load-bearing of bearings at both ends and middle steel axle, require all higher, and, weight capacity is very limited, in the loss of cabling process middle (center) bearing, is larger, and existing cabling speed is slow, need the shortcomings such as artificial many, potential safety hazard is large still to exist.

Utility model content

The deficiency existing for prior art, the utility model proposes a kind of cable unwinding device, can the some dish cable of single step of releasing, and pallet automatic rotation during due to unwrapping wire, torsion discharges automatically, thereby can not cry strength distortion, and cable laying is smooth and efficient.

The technical scheme the utility model proposes is as follows:

, comprise vertical shaft and drum, it is characterized in that, also comprise applanation bearing; Described applanation bearing shaft is to the bottom surface that is connected to described drum; Described vertical shaft passes in the middle of described drum, interconnects with described drum; Wherein, described vertical shaft is with described drum for being flexibly connected, and described flexible connection is that clamping or screw-in mode connect.

Wherein, adopt bolt that described pressure bearing is axially connected with described drum.

The beneficial effects of the utility model are: this device has structurally utilized the feature of applanation bearing, can load-bearing can easily rotate again, thereby reach the object of efficient unwrapping wire.

Accompanying drawing explanation

Fig. 1 is the structure chart of cable unwinding device of the present utility model;

Description of reference numerals:

101-vertical shaft 102-drum 103-applanation bearing

Embodiment

Below in conjunction with drawings and Examples, the utility model is described further.

Cable unwinding device as shown in Figure 1, comprises vertical shaft 101 and drum 102, it is characterized in that, also comprises applanation bearing 103; Described applanation bearing 103 is axially connected to the bottom surface of described drum 102; Described vertical shaft 101 passes in the middle of described drum 102, interconnects with described drum 102.

Wherein, described vertical shaft 101 with described drum 102 for being fixedly connected with.

Wherein, described flexible connection is that clamping or screw-in mode connect.

Wherein, adopt bolt that described applanation bearing 103 is axially connected with described drum 102.

The vertical shaft 101 of this cable unwinding device also can adopt and be flexibly connected with described drum 102, such as adopting clamping or screw-in mode to connect, so that device carries, when this cable unwinding device is used, level is placed in ground, cable is placed on drum 102, from outer ring, starts to put.Vertical shaft 101 passes in the middle of drum 102, can avoid unwrapping wire drum when last to collapse, and affects unwrapping wire efficiency.This device has structurally utilized the feature of applanation bearing, can load-bearing can easily rotate again, thereby reach the object of efficient unwrapping wire.

In building intelligent system engineering light current cable laid processes, if free-hand unwrapping wire needs everyone the hand-held hank of cable, two sides upset unwrapping wire, if need to lay five cables simultaneously, needs at least six people, and because needs overturn cable back and forth, so the unwrapping wire time is long.Adopt this cable unwinding device only to need two people's operations, using is manually 1/3rd of hand operation, and unwrapping wire is smooth, more than the twice that payingoff speed is hand operation.

Finally it should be noted that above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment; those of ordinary skill in the field are to be understood that; still can modify or part technical characterictic is equal to and replaces and do not depart from the spirit of technical solutions of the utility model embodiment of the present utility model, it all should be contained in the middle of the technical scheme scope that the utility model asks for protection.
