Abstract
A lateral pressure detecting device during cable laying comprises a turning wheel, a pressure controller, a controller and a display. The pressure sensor is mounted at the corner of a cable trench. The turning wheel is mounted between the pressure senor and a cable. The pressure sensor is used for detecting the lateral pressure in real time and generating corresponding electric signals. The controller transmits the lateral pressure signals to the display according to the electric signals of the pressure sensor to allow the display to display lateral pressure value in real time. By the lateral pressure detecting device which is simple to operate, accurate in detecting result, free of manual calculation, time saving and labor saving, the lateral pressure can be detected and measured directly, and errors caused by human judgment can be avoided.
Description
Technical field
Wall pressure pick-up unit while the present invention relates to a kind of cable laying.
Background technology
High-tension cable system of laying comprises poling, tunnel and direct-burried etc., and laying-out is complicated, and turning is many, to cabling, causes larger difficulty.For crosslinked cable, generally by paying out machine, draw drawing head and carry out cabling, when meeting corner, cable is subject to the effect of tractive force, the component of tractive force and reacting force form the wall pressure of cable, if wall pressure is excessive, will flatten cable, even can damage the insulated hull of cable, thereby affect the insulating property of cable.At present, the wall pressure producing during to cabling is generally calculated by formula P=T/R, wherein, P is wall pressure, and T is the tractive force acting on cable, R is the radius of bending cable, but in practice of construction process, variable T and R are uncertain factor, all by artificial judgment, record, thereby make the wall pressure of finally calculating have larger error, affect engineering construction.
Summary of the invention
For the deficiencies in the prior art, wall pressure pick-up unit when object of the present invention is intended to provide a kind of cable laying, it is detection side pressure accurately.
For achieving the above object, the present invention adopts following technical scheme:
Wall pressure pick-up unit during cable laying, it comprises turning wheel, pressure transducer, controller and display; Pressure transducer is arranged on the corner of cable duct, and the wheel of turning is arranged between pressure transducer and cable; Pressure transducer is used for real-time detection side pressure, and generates corresponding electric signal; This controller according to the electric signal transmitter side pressure signal of pressure transducer to this display, so that display shows wall pressure value in real time.
Further, the quantity of taking turns of turning is a plurality of, and the quantity of pressure transducer, controller and display is identical with the quantity of the wheel of turning, and each pressure transducer corresponding is turned and taken turns, each pressure transducer is electrically connected a controller, and each controller is electrically connected a display.
Beneficial effect of the present invention is as follows:
The present invention can direct-detection and is shown wall pressure, and simple to operate, testing result is accurate, without calculating by artificial, and the error of avoiding artificial judgement to produce, time saving and energy saving.If wall pressure surpasses higher limit, staff can regulate placed angle and the position of tractive force size or the wheel of turning in time, so that wall pressure is controlled at below higher limit.
Accompanying drawing explanation
The schematic diagram of the better embodiment of wall pressure pick-up unit when Fig. 1 is cable laying of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described further:
Refer to Fig. 1, wall pressure pick-up unit while the present invention relates to cable laying, its better embodiment comprises turn wheel 50, pressure transducer 60, controller 20 and display 10.
When the cabling of corner, cable 40 produces wall pressure under the effect of tractive force F, the real-time detection side pressure of pressure transducer 60, and generate corresponding electric signal, this controller 20 according to the electric signal transmitter side pressure signal of pressure transducer 60 to this display 10, so that display 10 shows wall pressure value in real time, thereby make staff can understand intuitively the wall pressure of turning cable, if wall pressure surpasses higher limit, staff can regulate placed angle and the position of tractive force size or the wheel of turning in time, so that wall pressure is controlled at below higher limit.
When the quantity of the wheel 50 of turning is while being a plurality of, the quantity of pressure transducer 60, controller 20 and display 10 is identical with the quantity of the wheel 50 of turning, each pressure transducer 60 corresponding one is turned and is taken turns 50, each pressure transducer 60 is electrically connected a controller 20, each controller 20 is electrically connected a display 10, to show intuitively the wall pressure of a corresponding turning wheel 50 by each display 10.
The present invention can direct-detection and is shown wall pressure, and simple to operate, testing result is accurate, without calculating by artificial, and the error of avoiding artificial judgement to produce, time saving and energy saving.If wall pressure surpasses higher limit, staff can regulate placed angle and the position of tractive force size or the wheel of turning in time, so that wall pressure is controlled at below higher limit.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion all should belong to the protection domain of the claims in the present invention within.
