Description
Technical field
The utility model belongs to power construction field instrument, is specifically related to a kind of cable pipe and lays and use mouth of pipe leading block.
Background technology
In power cable layer work, because the situation of cable installation in pipe is comparatively complicated, need the more and constantly guard of manpower in the laid processes, cable is withstanding on the steel pipe or cable is scratched by steel pipe nozzle easily simultaneously.Crowded, narrow and small when the present position, pulley is not placed, and can cause cable to be obstructed when the mouth of pipe turns round, and lays the drawbacks such as pulling force is larger, causes cable impaired easily, and resistance is larger, and progress is incured loss through delay.
Lay in the work at cable pipe, manpower is just more relied on, along with the human cost cumulative year after year, construction cost all increases.
1) professional skill field aspect: in power cable layer work, the situation more complicated of cable installation in pipe (steel pipe, comb, bellows, PE pipe lay etc.).Need manpower more and need constantly personnel to guard in the laid processes, scratch when cable enters the mouth of pipe or withstands on the steel pipe or by steel pipe nozzle easily when the mouth of pipe turns round, cause cable cover(ing) or insulate impaired.
2) security protection aspect: in the past in cable pipe lays, the pulley that uses must rely on manpower that it is supported on mouth of pipe edge, because the weight of cable own is very large, strengthened so undoubtedly the personal safety hidden danger in the work progress, poling direction guiding to cable is ineffective, so that also there are major safety risks in cable machinery.
3) construction technique aspect:
At some environment, because the restriction of site environment or laid many cables, so that the cable present position is crowded, narrow and small, the instrument such as pulley, crowbar is not placed, be difficult to the placement technique measure, finally cause cable seriously to be obstructed when the mouth of pipe turns round, cable scratches, when entering the mouth of pipe, withstood by cable, Cable Bending Radius is less, lays the drawbacks such as pulling force is larger, causes cable impaired easily, resistance is larger, and progress is incured loss through delay.
Lay in the work at cable pipe, very easily cause the cable insulation damage during cable incoming-outgoing comb mouth of pipe, this phenomenon is passed two combs and two combs are more obvious when having high low head successively at cable, and difficulty of construction is larger, and is also even more serious to the damage of cable.
4) human resources aspect: cable installation in pipe mode in the past and the instrument that adopts, exist in practice such as the needs nurse, need to support, use restricted, the disadvantage such as waste of manpower is more.In recent years, the cost of human resources cumulative year after year had so just caused all increasing of construction cost.
Therefore, need a kind of pulley of design, have the function of guiding, can protect cable can save manpower again.
The utility model content
The purpose of this utility model provides the mouth of pipe leading block that a kind of cable pipe lays usefulness, breaks through the limitation that traditional cable installation in pipe relies on manpower in a large number, has both protected cable injury-free, saves in a large number again construction cost; Its practical, easy and simple to handle, safety labor-saving, greatly improve efficiency of construction, effectively saved project cost.
The purpose of this utility model realizes by following technical proposals.
A kind of cable pipe lays uses mouth of pipe leading block, comprises tube seat, pulley bracket and pulley, and described pulley is connected to pulley bracket one end by its pulley spindle, and the other end of pulley bracket connects a tube seat.
Further, in described mouth of pipe leading block, tube seat is that the cross section is semicircle arcuation cell body, and the length of tube seat is 25cm or 50cm.
Further, in described mouth of pipe leading block, the height of pulley axle is higher than tube seat groove bottom height 20mm.
The utility model tube seat stretches into from the mouth of pipe of the pipeline that needs cabling, and cable penetrates the mouth of pipe from pulley one end along tube seat.The mouth of pipe leading block of making can play when being placed on tube seat in the pipeline, and cable passes does not from it just need manpower to help, fix, easy to operate, simple and safe.Cable is considered the minimum bending radius of cable when the mouth of pipe turns round simultaneously, and the length of tube seat and the radian of tube seat satisfy the site operation needs.Mouth of pipe leading block is also considered the difference in height of pulley and tube seat position, has avoided cable to cause at the edge of tube seat and has hung wound.Mouth of pipe leading block also will be considered cable in the turning situation of the mouth of pipe, and when the mouth of pipe changed the direction of power, reply freely.In cable pipe lays, directly the tube seat with mouth of pipe leading block is placed in the pipeline, does not need the staff to help, fix, and is just more smooth and easy when cable enters pipeline, during the cable incoming-outgoing mouth of pipe, about can also realizing, any direction freely leads flexibly up and down.
Description of drawings
Fig. 1 is mouth of pipe leading block structural representation.
Among the figure: 1, tube seat; 2, pulley bracket; 3, pulley.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further details.
As shown in Figure 1, a kind of cable pipe lays uses mouth of pipe leading block, it is characterized in that, it is comprised of tube seat 1, pulley bracket 2 and pulley 3 three parts, and pulley 3 is installed in an end of pulley bracket 2, and pulley bracket 2 other ends and tube seat 1 weld together; Behind vertical pipe cutting, steel pipe is welded formation tube seat 1 along joint-cutting again according to certain radian, tube seat 1 is semicircle arcuation cell body for the cross section; Tube seat 1 stretches into from the mouth of pipe of the pipeline that needs cabling, and cable penetrates the mouth of pipe from pulley 3 one ends along tube seat 1.
Wherein, tube seat 1 is welded by the steel pipe cutting, this leading block design is divided into two kinds, a kind of tube seat 1 length is 50cm, be suitable for the larger big section copper core wireline operation of cable bending radius when the mouth of pipe turns round, a tube seat part is inserted pipeline, expose 20cm in the pipeline outside, increase the bending radius of cable; Another kind of tube seat 1 length is 25cm, and range of application is wider, is suitable for various cables and penetrates the operation that the mouth of pipe, the mouth of pipe turn round.
The weight of tube seat 1 is larger than the weight 0.5kg of pulley 3+ pulley bracket 2～1kg, when being placed on tube seat 1 in the pipeline like this, cable pass from it just do not need manpower help, fixing, easy to operate, simple and safe; To consider the external diameter of cable for the radian of tube seat, consider the external diameter of 110kV electric cable with large cross-section, 35kV turnkey electric cable with large cross-section, steel pipe is vertically cut, be welded into again as requested the tube seat of certain radian; The height of pulley axle will be higher than tube seat bottom surface 20mm, has so effectively avoided cable to hinder because the edge of tube seat causes to hang.
This mouth of pipe leading block is applied in during cable pipe lays, practical, easy and simple to handle, safety, more laborsaving than prior cable laying pulley, it is little to take up space, guiding flexibly, effective guarantee the construction in personal safety, greatly improved efficiency of construction, the spoilage of cable is obviously reduced, the manpower that uses in the cable laying obviously reduces, and has effectively saved project cost.
