Description
Technical field
The utility model belongs to a kind of pulling force sensor, specifically, relates in particular to a kind of tension measurement bearing pin.
Background technology
Behind the boats and ships landing pier, the hawser on the ship must tie up on the release mooring hook of harbour, and needs the safety of accurate, the stable stressing conditions of knowing hawser to guarantee that boats and ships are stopped.Domestic because technical merit limits, can't accurately measure the stressing conditions of hawser.The monitoring bearing pin that uses all is to adopt import at present, cost an arm and a leg, and after sale service inconvenience, the use of monitoring bearing pin to pulling force brings significant limitation.At present, also there is not a kind of stressing conditions of accurately measuring hawser can satisfy boats and ships and stop the time, and tension measuring device simple to operate, that usable range is wide.
Summary of the invention
The cable stress situation is measured accurately inadequately when stopping in order to solve in the prior art boats and ships, and import instrument costs an arm and a leg, uses inconvenient defective, and the utility model provides a kind of tension measurement bearing pin.
Be achieved through the following technical solutions during the utility model:
A kind of tension measurement bearing pin comprises axis body, and axis body inside is provided with electric signal amplifier, and the top layer is provided with two stress sections, and outer wall is provided with signal cable lifts one's head, and links to each other by signal wires between electric signal amplifier, stress section and signal cable are lifted one's head.
Axis body inside preferably is provided with oilway and lubricator cup, and lubricator cup leads to the axis body outside by oilway; One end of axis body preferably is provided with the axle head capping, preferably is provided with insulating pad in the axis body between axle head capping and the electric signal amplifier; Preferably be provided with O-ring seal between axle head capping and the insulating pad; Preferably scribble fluid sealant on the stress section; Signal cable is lifted one's head and can be connected with signal wires by cable sealed joint; Preferably be provided with plug on the stress section.
Compared with prior art, the beneficial effects of the utility model are: can be accurate, stable in good time monitor the pulling force numerical value that boats and ships are stopped the back hawser, and numerical value passed to the pulpit on computer display screen, present; Electric signal amplifier is installed in the inside of bearing pin, by cable sealed joint signal cable is drawn the axis body outside, does not need to be provided with an electric signal amplifier mounting box again, has reduced the installation procedure and the loss of signal, compact appearance, structure simple installation; Being got up the electric signal amplifier insulated enclosure by axle head capping and O-ring seal and insulating pad in the end, has further improved the degree of accuracy of measuring, and prolonged serviceable life.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Axle head capping in the drawings, 1; 2, O-ring seal; 3, insulating pad; 4, electric signal amplifier; 5, signal wires; 6, stress section; 7, plug; 8, fluid sealant; 9, oilway; 10, lubricator cup; 11, cable sealed joint; 12, signal cable is lifted one's head; 13, first fixed side; 14, tension axle sleeve; 15, second fixed side; 16 axis bodies.
A kind of tension measurement bearing pin comprises axis body 16, and axis body 16 inside are provided with electric signal amplifier 4, oilway 9 and lubricator cup 10, and the top layer is provided with two stress sections 6, and outer wall is provided with cable sealed joint 11 and signal cable lifts one's head 12; Signal cable is lifted one's head and 12 is located on the cable sealed joint 11, link to each other by signal wires 5 between electric signal amplifier 4, stress section 6 and the cable sealed joint 11, lubricator cup 10 leads to axis body 16 outsides by oilway 9, and stress section 6 is provided with plug 7 and scribbles fluid sealant 8; One end of axis body 16 is provided with axle head capping 1, is provided with O-ring seal 2 and insulating pad 3 in the axis body 16 between axle head capping 1 and the electric signal amplifier 4.
In use, the utility model is installed in the tension axle sleeve 14, and fixing by first fixed side 13 and second fixed side 15.Under the effect of tensile force f, tension axle sleeve 14 makes the axis body 16 that is fixed in first fixed side 13 and second fixed side 15 be subjected to shearing force at stress section 6 places, axis body 16 produces physical deformation changes the resistance value of stress section 6, by electric signal amplifier 4 conversion of signals is become voltage signal or current signal output then, demonstrate value of thrust by instrument.
The course of work of tension measurement:
Mechanical load input → stress bearing pin strain → sensor signal conversion → signal amplification → scene demonstration → central control system.
Resistance between two stress sections is 350 ohm.Electric signal amplifier adopts wheatstone bridge configuration to carry out wiring.
Resistance after carefully connecting the wire between each line:
Red---between deceiving is 350 ohm
Green---be 350 ohm between white
Red---be 263 ohm between green
Red---be 263 ohm between white
Black---be 263 ohm between green
Black---be 263 ohm between white
It is 12VDC that signal amplifier inserts power supply, and the output signal electric current is 4-20mA.
