Background technology

2011; international and domestic Ministry of Labour regulation; hoisting crane mandatory requirement mounting torque killer more than 1 ton; China's limiter of moment is started late; the eighties in last century; Beijing computer copies the product design of Japanese many fields company to produce domestic first generation limiter of moment product, and relevant criterion GB 12602-2009 " elevator machinery overload protection device " has been decided in the 2009 annual overhauls transformations of the way.

The imported product quality is better at present; but price is 5 times of left and right of domestic brand; the home products price is lower; but due to the impact that is subjected to sensor kit etc.; the home products less stable; the signal drift that wherein causes due to impacts such as sensor is hit, vibration, temperature is the one of the main reasons that causes the limiter of moment Frequent Troubles; especially for a long time work in the shock and vibration environment; usually because sensor is hit, vibrates and cause signal drift, finally cause equipment to can't harm disorderly closedown.

The utility model content

The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is: a kind of moment restriction apparatus with reset function is provided.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of moment restriction apparatus with reset button comprises: limiter of moment is controlled mainboard, LCD touch display screen, clock module, logout module, logic control circuit, sound and light alarm module, height limit switch, linear transducer, angular transducer, weight sensor and power module;

Described LCD touch display screen, clock module and logout module are controlled mainboard with limiter of moment respectively and are connected; After the signal output part serial connection photoelectricity isolation output module of described limiter of moment control mainboard, the input end of andlogic control circuit is connected, described LCD touch display screen is provided with the parameter reset function key, and the mouth of described logic control circuit is connected with the sound and light alarm module;

Be connected with the signal input part of limiter of moment control mainboard after the mouth serial connection photoelectricity Isolation input module of described height limit switch; The mouth of described linear transducer, angular transducer and weight sensor is connected with the signal input part of limiter of moment control mainboard after being connected in series respectively First Line sexual isolation filtration module, the second linear isolation filtration module and the 3rd linear isolation filtration module;

Described power module is whole moment restriction apparatus power supply.

Described power module includes direct supply and DC/DC insulating power supply module, and the mouth of described direct supply is connected with the input end of DC/DC insulating power supply module.

The beneficial effect that the utility model compared with prior art has is: the utility model parameters reset function key, the user can pass through parameter reset function key self-resetting correlation parameter, the system alarm error that the device parameter that elimination causes due to the sensor zero point drift changes and causes, this function can repeated usage, effectively reduces the past-sale service expense of Stop-Time of Device Failure and manufacturer; Whole apparatus structure is succinct, and is practical.
