Description
Technical field
The present invention relates to a kind of power cable traction coasters.
Background technique
With the rapid development of our country's economy, the city size as its development mark is also growing, modern city function
Can the requirement to power supply be also continuously improved, in urban high-rise building mansion ever-increasing today, for traditional overhead power transmission
Line should be noted that the association of arrangement and the urban development of line corridor in the urban area of Quick Extended across many obstacles are brought especially
It adjusts, avoids falling into it among tight encirclement of urban architecture quickly.To the overhead transmission line for having fallen into city, it is generally desirable to tie
Conjunction is transformed into greenbelt or underground cable line.
The present buried cable overwhelming majority is located among comb channel, and the comb in comb channel has metal tube and modeling
Point of expects pipe, the comb anti-settling ability for being embedded in underground is very weak, and part, which squeezes, is easy for generating bending or displacement.Additionally arranging electricity
When cable, power worker first opens the well lid on electric power inspection shaft, and the cable for carrying out drag hook is put into comb mouth, is then draged with electric power
Draw machinery to win over cable from comb by other electric power inspection shaft.Like that, in cable penetration, cable jacket still can be with
Comb inner wall generates fierce sliding friction, is especially bent or shifts location in comb, is passed through every time to cable and comb all
There is certain damage, not only traverse velocity is extremely slow in this way, and repeatedly passes through and be possible to cause scrapping for cable and comb.
We also need targetedly to develop thus, to solve the above problems, extend the service life of cable and comb.
Summary of the invention
For above-mentioned problem, the present invention provides a kind of power cable traction drum-type coaster, it from heavy and light and more compact,
It can be located among cable using the difference of the limit of cable size and comb diameter and pass through comb and card resistance and comb will not be increased bear
Lotus；It can install easily and be distributed among cable, and when making to additionally arrange cable, cable jacket will not generate frictionally damage, Er Qiepai
Fierce sliding friction is also changed to rolling friction by inside pipe wall, along with the material of drum-type pulley, to essentially eliminate to row
The injury of pipe.
The present invention is implemented as follows: power cable traction drum-type coaster is characterized in: drum-type coaster is distributed at intervals
In the cable, it is synthesized, is fixed in the cable with lower carriers assembly by the arc-shaped upper cover plate in drum-type coaster；
The lower carriers assembly, preceding support, rear support are by cutting H-type groove in lower carriers bottom plate, and then bending forms, and
One notch is formed below it；Drum-type pulley is located at preceding support through pin shaft, among rear support；The circle of lower carriers bottom plate
Arc is more than 200 °, and the lateral separation of drum-type pulley is more than 85 °.
The material of drum-type pulley includes high lubrication thermostabilization fire proofing；The full section of drum-type pulley is in drum type, and both ends are
The chamfering of limit.
Effect of the invention is:
1. the manufacturing method of preceding support, rear support in its lower carriers assembly not only saves material, simplifies manufacturing process, and
Possess a notch below drum-type pulley, the height of drum-type pulley can be reduced, to reduce the outer diameter of Universal scooter, just
In passing through comb.
2. it can make it be located at cable from heavy and light and more compact using the difference of the limit of cable size and comb diameter
Among pass through comb will not card resistance and increase comb load.
3. it can install easily and be distributed among cable, when installation, need to only screw on 4 screws just, additionally arrange cable
When, cable jacket would not generate frictionally damage.
4. its shape of drum-type pulley that it is contacted with comb inner wall is in drum type, contact range thus can increase, reduce row
The pressure of inside pipe wall, along with the material of drum-type pulley, the sliding friction of original fierceness is changed to present Gao Run by comb inner wall
Sliding rolling friction damages it not through repeatedly passing through to essentially eliminate the injury to comb.
5. it is all dispersed with drum-type pulley assembly in cable lower periphery, and thus being formed can connect with 170 ° of comb inner wall
The coaster of touching enables cable to play unique effect when passing through comb bending or displacement location.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the stereoscopic schematic diagram of power cable traction drum-type coaster of the present invention.
Fig. 2 is the main view of power cable traction drum-type coaster of the present invention.
Fig. 3 is the partial enlarged view of power cable traction drum-type coaster of the present invention.
In figure: 1. drum-type coasters, 2. cables, 3. upper cover plates, 4. lower carriers assemblies, 5. drum-type pulleys, 6. pins
Axis, support before 7., 8. notches, 9. rear supports.
Specific embodiment
As shown, drum-type coaster 1 is distributed at intervals in cable 2, by the arc-shaped upper cover plate 3 in drum-type coaster 1
It is synthesized with lower carriers assembly 4, is screwed in cable 2, is all dispersed with drum-type pulley in the lower periphery of cable in this way
Assembly just forms the coaster that can be contacted with comb inner wall many places, and cable is enable to play when passing through comb bending or displacement location
Unique effect.
The preceding support 7 of lower carriers assembly 4, rear support 9 are by cutting H-type groove in lower carriers bottom plate, and then bending forms,
And one notch 8 is formed below it；Support 7 before drum-type pulley 5 is located at through pin shaft 6, among rear support 9；Lower carriers
The circular arc of bottom plate is more than 200 °, and the lateral separation of drum-type pulley 5 is more than 85 °.
The material of drum-type pulley 5 includes high lubrication thermostabilization fire proofing；The full section of drum-type pulley 5 is in drum type, both ends
For the chamfering of limit.
When additionally arranging wireline operation, power worker first opens the well lid on electric power inspection shaft, and the cable for carrying out drag hook is put into
In comb mouth, then cable is won over from comb by other electric power inspection shaft with electric power traction machine tool, at the same time, constantly
Drum-type coaster is loaded onto, is distributed in it among cable at intervals, not only completely eliminates the frictionally damage of cable jacket in this way,
And the sliding friction of original fierceness is changed to present high lubrication rolling friction by comb inner wall, to essentially eliminate to comb
Injury, so that it is repeatedly passed through and is not damaged.
Structure of the invention is not limited to form described in embodiment, and those skilled in the art make according to the present invention
It is further expansion each fall within protection scope of the present invention.
Power cable traction drum-type coaster of the present invention is very suitable for using in narrow comb space, it is inexpensive, flexibly and
Actual effect is good.
