The cable well protection device can greatly reduce an electric power cable laying resistance during the cable laying, can effectively protect cables, cable pipes and a cable well base, improves production efficiency and provides a safety guarantee for the cable laying; and the cable well protection device is simple in structure, easy to operate and strong in practicality.
Description
Technical field
The utility model relates to cable laying construction tool technical field, and specifically one can be protected the not impaired cable shaft protective device in cable, cable duct and cable shaft basis in cable laying process.
Background technology
At present, cable duct adopts comb mode more, and cable, in laid processes, can become greatly to destroy to cable, cable duct and cable shaft foundation.The pull rope comb upper tube wall that rubs for a long time during due to cable laying, and always worn out to cable shaft basis from comb mouth, change the running orbit of cable, cable is dragged in the pipeline damaging, cause the destruction on cable, cable duct, cable shaft basis, seriously reduce the production efficiency of cable laying, and caused larger economic loss.Research is a kind of protects the not impaired cable shaft protective device in cable, cable duct and cable shaft basis extremely urgent in cable laying process.
Summary of the invention
For solving cable cable, cable duct, the destroyed problem in cable shaft basis in laid processes, goal of the invention of the present utility model is to provide a kind of cable shaft protective device, to realize the object on effective protection cable, cable duct and cable shaft basis.
For achieving the above object, the utility model comprises two parts, the both sides of cable shaft protective device and cable borehole wall contact-making surface be fixed as standing part in well, well head be fixed as well youngster's standing part.
In described well, the cylinder of the antifriction fixed support surfaces one of teeth type of standing part is subject to, on mechanical axis, resting barrel is housed, and on the leading screw of the antifriction fixed support surfaces two of teeth type, is rotary with regulating flange, and screw set is in cylinder is subject to mechanical axis.
On the coaster base of described well youngster's standing part, be fixed with pulley one with coaster connecting bolt, pulley one, pulley two, pulley three use coaster connecting bolts connect into collapsible three fixed block groups.
Described resting barrel can be packaged type pulley.
The utility model is installed with standing part in the well of resting barrel or packaged type pulley structure near the pre-outlet spout of cable position in cable shaft, by rotating regulating flange, promote the antifriction fixed support surfaces of teeth type of both sides, the antifriction fixed support surfaces of teeth type is supported and fixed on the borehole wall of both sides, resting barrel or packaged type pulley compacting pull rope and cable, the trend of controlling pull rope and cable, prevents pull rope and cable and upper tube wall friction.Collapsible three fixed block groups are arranged on cable and pull rope and go out in advance the upper end of pithead position, can effectively lift cable, control pull rope and cable louding, do not allow itself and well youngster friction, frictional resistance when minimizing cable goes out well head.The friction destructive power that the utility model bears cable duct is transferred in resting barrel or packaged type pulley and collapsible three fixed block groups, has avoided pulling force friction because of pull rope and the cable destruction to cable, cable duct and cable shaft basis.By being used in combination of two devices, change the running orbit of pull rope and cable, make sliding friction be transformed into rolling friction, avoid the destruction on cable, cable duct and cable shaft basis.
The utility model compared with prior art, has greatly reduced power cable layer resistance in cable laying process, can effectively protect cable, cable duct, cable shaft basis, and improving production efficiency, for cable laying provides safety guarantee.Structure and simple to operate, practical.

Fig. 2 is the structure diagram of the interior standing part (with resting barrel 2) of well of Fig. 1.
Fig. 3 is the structure diagram of well youngster's standing part of Fig. 1.
Fig. 4 is the structure diagram of the interior standing part (with packaged type pulley 13) of well of Fig. 1.
Embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, cable shaft protective device comprises two parts, and the fixed form of its both sides and cable borehole wall contact-making surface adopts standing part 14 in well to fix, and the fixed form of well head adopts well youngster's standing part 15 fixing.
In well, the cylinder of the antifriction fixed support surfaces 1 of teeth type of standing part is subject to, on mechanical axis 3, resting barrel 2 is housed, and on the leading screw 4 of the antifriction fixed support surfaces 26 of teeth type, is rotary with regulating flange 5, and leading screw 4 is enclosed within cylinder and is subject in mechanical axis 3.Resting barrel 2 can be packaged type pulley 13.Adopt resting barrel 2, stability is high, is applicable to large-sized cable construction; And adopt packaged type pulley 13, lightweight, flexible operation, is applicable to the construction of mini-cable.By rotating regulating flange 5, promote the antifriction fixed support surfaces 1 of teeth type and the antifriction fixed support surfaces 26 of teeth type of both sides, the antifriction fixed support surfaces of teeth type is supported and fixed on the borehole wall of both sides.
On the coaster base 7 of well youngster's standing part, be fixed with pulley 1 with coaster connecting bolt 9, pulley 1, pulley 2 10, pulley 3 12 use coaster connecting bolts 11 connect into collapsible three fixed block groups.The position that this utility model is positioned over to cable and goes out in advance well head, is vertically placed in pulley 3 12 in well, and as spare wheel, pulley 1, pulley 2 10 are as working sheave.Pulley 1, pulley 2 10, pulley 3 12 adopt No. 35 steel column global formations, have increased the tensile strength of coaster self, have effectively protected cable, cable duct and cable shaft basis not to be destroyed.The utility model, on the basis of traditional three coasters, has extended the width of coaster base 7, can strengthen the stability of coaster entirety.Original three coasters, because move draw-gear position, cause pull rope or cable in the time going out well head, to depart from original track, add overhanging cable and cable downward pressure in the time going out well head excessive, cause three coasters of original design by high high bounce, have potential safety hazard.Widen coaster base 7 and can effectively prevent the generation of this type of accident.Meanwhile, three Combined pulley height of original three coaster are identical, cause pull rope and cable in motion process, often only have a pulley stressed, not only increased cable pulling resistance, also reduced coaster useful life.The utility model has adopted pulley 1, pulley 2 10 highly high, the design that pulley 3 12 is highly low, by the high low head design of pulley staggered floor, guarantee each pulley uniform stressed, can guarantee that pull rope and cable two pulleys in distraction procedure are simultaneously stressed, not only reduce tractive resistance, increased the useful life of coaster itself simultaneously.
