Description
Technical field
The utility model belongs to cable laying equipment field, especially relates to a kind of cable laying wall pressure pick-up unit.
Background technology
Run in high-tension cable laid processes when turning round and often bend because being subject to lateral pressure, time bending, be stretched outside cable, inner side is extruded.Due to cable material and architectural characteristic, if wall pressure is excessive, will cable be flattened, even can damage the insulated hull of cable, thus affect the insulating property of cable.At present, generally calculated by formula P=T/R the wall pressure produced during cabling, wherein, P is wall pressure, T is the tractive force acted on cable, R is the radius of bending cable, as can be seen here, under the condition that tractive force is certain, increase Cable Bending Radius, can reduce wall pressure suffered by cable, otherwise reduce Cable Bending Radius, wall pressure suffered by cable increases.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of cable laying wall pressure pick-up unit, change the situation that existing cable wall pressure pick-up unit can only measure wall pressure, once cable side pressure exceedes threshold value, automatically increase Cable Bending Radius, adjust in time without the need to people.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of cable laying wall pressure pick-up unit, comprise base, roller, controller, display screen and pressure transducer, also comprise photoelectric sensor, a screw rod is had in described base, displacement transducer is provided with in described screw rod, two supports are provided with on described base, described support is flexibly connected with between screw rod, support is provided with rotating shaft, described rotating shaft is provided with the controlled roller of radius, holder part between described roller and screw rod is provided with pressure transducer, two roller spacings are provided with two photoelectric sensors from nearest two subpoints on base, described photoelectric sensor radiating portion and receiving unit are integral type.
Further, described roller changes the size of its radius by charging and discharging gas, its excircle and conductive cable contacts part are covered with rubber layer, and reduce the wall pressure of cable by increasing described roller radius, described rubber layer can reduce the damage to cable sheath.
Further, described rotating shaft with charge and discharge gas motor and be connected, for charging and discharging gas to roller, control the size of roller radius.
Further, described screw rod two ends are provided with the contrary screw thread in direction, by clockwise or rotate counterclockwise screw rod, control two stands away from each other or close, thus to control between two rollers away from each other or close.
Further, described control sensor and photoelectric sensor, pressure transducer, displacement transducer, screw rod, inflator pump motor connected mode are for be electrically connected, controller sends steering order to screw rod and charge-discharge machine, controller work after receiving pressure transducer, photoelectric sensor, displacement transducer information.
Further, described controller is also connected with warning horn, and when side pressure value is greater than preset value, warning horn gives the alarm.
The advantage that the utility model has and good effect are: can Real-Time Monitoring cable side pressure, the bending radius of cable is increased by increasing roller radius, and then reduce the wall pressure of cable, also by constantly reducing roller radius to reduce the bending radius of cable, the minimum bending radius of cable under detection limit wall pressure is used for.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, a kind of cable laying wall pressure pick-up unit, comprise base 1, roller 2, controller 3, display screen 4 and pressure transducer, also comprise photoelectric sensor 5, a screw rod 13 is had in described base 1, displacement transducer is provided with in described screw rod 13, two supports 11 are provided with on described base 1, be flexibly connected between described support with screw rod 13, support 11 is provided with rotating shaft 12, described rotating shaft 12 is provided with the controlled roller of radius 2, support 11 part between described roller 2 and screw rod 13 is provided with pressure transducer, the subpoint of nearest 2 of two roller 2 spacings on base 1 is provided with two photoelectric sensors 5, described photoelectric sensor 5 radiating portion and receiving unit are integral type.
Embodiment 1, reduces cable side pressure.
During original state, between the light that described photoelectric sensor 5 sends and two rollers 22 of minimum distance tangent, roller 2 rotates along with cable movement, its tractive force is sent on controller 3 by the pressure transducer on support, when cable side pressure is greater than preset value, controller 3 controls gas charge-discharge machine pair roller 2 and inflates, in this process, roller 2 radius increases, photoelectric sensor 5 can detect reflected light, photoelectric sensor 5 feeds back to controller 3, controller 3 controls screw rod 13 and moves along a direction, make two rollers 2 away from each other, until photoelectric sensor 5 can't detect reflected light, now roller 2 displacement information of displacement transducer record can determine roller 2 radius, and then determine Cable Bending Radius, wall pressure suffered by cable can be obtained by tractive force and Cable Bending Radius.
Embodiment 2, the wall pressure under different radii.
During bending radius corresponding to detection streamer ultimate power, need to detect wall pressure corresponding to different radii, in this case, Cable Bending Radius reduces gradually, first by screw rod 13 adjusting pole 11 distance, reduce the distance between support 11 center line and photoelectric sensor 5, and be set to radius of target value, now, photoelectric sensor 5 can detect reflected light, then controller 32 controls inflation/deflation motor and exits to roller 2, until photoelectric sensor 5 just can't detect reflected light, now radius of target value equals radius value, can by wall pressure suffered by pressure transducer and radius value determination cable.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
