Description

Disturbance rejection overload protection type generating strand is grinding integrated

Technical field

The utility model relates to a kind of small machine for constructing, and particularly relates to the maneuvering milling machine of traction and lifting use, belongs to maneuvering milling machine technical field.

Background technology

In engineering construction, maneuvering milling machine is a kind of service tool of frequent use, and particularly in operation in the wild, maneuvering milling machine provides indispensable external impetus for constructing.During simultaneously due to field construction, the charging of Communication Equipment needs power supply with the illumination of on-the-spot nurse at night, is conventionally difficult to draw at the scene and establishes common 220V line powered, needs adapted small generator to solve powerup issue.

In engineering construction, tractor equipment provides mechanical power by bracing wire, helps people to complete lifting, the transfer of material.Big-and-middle tractor equipment is because it provides power large, for guaranteeing bracing wire safety, prevents bracing wire and ruptures because of overload, sensor has been installed in its system and has been used for monitoring in time pulling force and meets and exceeds when standard is set and quit work in time at pulling force, avoids dangerous.Such as stretching machine.

And the small-sized construction equipment that engineering is used is at present maneuvering milling machine, it is mainly comprised of driving engine, change speed gear box and grinding barrel etc.There is pulley place card line, wire jumper in bracing wire sometimes, or tension object is stuck, or the heavier maximum safe limit using that exceeded of tension object, cause using maneuvering milling machine may produce the excessive unsafe condition of pulling force, failing timely discovery stops in time, cause machine to stop working and cause equipment damage, even can run into the situation of bracing wire broken string.Once accident occurs, and gently lags behind the duration, heavy cause casualties.Therefore the safe handling of line construction maneuvering milling machine pulling force should cause people's great attention equally with real time data monitoring and overload protection.

In addition, conventional general maneuvering milling machine is used power supply without accessory, does not therefore use electronic startup and adopts artificial pulling plate mode to start, and causes and uses trouble.Especially under the state of low-temperature cool starting, need repeatedly pulling plate.

The applying date is on December 30th, 2009, Granted publication number is CN201614245U, name is called the Chinese utility model patent of " with the maneuvering milling machine machine of overload protection device ", a kind of overload protection device for tractor-type maneuvering milling machine is disclosed, this utility model for maneuvering milling machine volume larger, brake mode is mainly for diesel engine, Brake Design is to adopt DC machine to pull drag-line to make the mode of clutch belt dish separation, for conventional small-sized in field, take the maneuvering milling machine that spark ignition engine is driving engine and do not do corresponding improvement, the direct shaft drive of the general employing of equipment of small motor strand grinding machine, do not use Pulley, therefore its braking method can not twist grinding machine for equipment of small motor.The requirement of power supply charging when this utility model is not considered field simultaneously, making equipment continue for a long time field studies has limitation.

The applying date is on November 18th, 2009; Granted publication number is CN201545644U; name is called the Chinese utility model patent of " a kind of hydraulic milling machine "; a kind of hydraulic milling machine is disclosed; although this strand grinding machine has tension measurement and overload protection function; but different from current widely used maneuvering milling machine transmission type, so its design distinguished is larger, is different from this equipment and considers the maneuvering milling machine using.

The applying date is on December 19th, 2012; Granted publication number is CN202967983U; name is called the Chinese utility model patent of " overload protection type intelligence strand grinding machine "; a kind of overload protection type intelligence strand grinding machine is disclosed; can play overload protection and quick electric start-up performance; but due to display measurement parts and the direct Electricity Federation of equipment power supply part, cause measurement to be easily disturbed in actual use.Because line tension test sensor output signal is fainter, need to amplify, extraneous electromagnetic interference and power supply noise all produce larger impact to signal.During device start, the moving strand mill of equipment power supply part and electric motor starter body Electricity Federation, electric current is larger, starter motor easily produces electro spark, cause larger electromagnetic interference, the same directly display measurement parts of Electricity Federation are easily caused to Interference from current, make to measure inaccurate.The moving strand mill of electric motor starter body self power generation alternating current during equipment operation; through the rectification accessory power supply to the device parts charging of himself carrying; the disorderly wave excitation of charging valtage of this mode is larger; produce larger power supply noise; for rechargeable battery, there is no any impact, but just can not ignore for the impact of the display measurement parts of direct Electricity Federation, badly influence survey precision and stability; even have influence on the judgement of overload protection, leave unsafe hidden danger.The use of attainable a tractor serves several purposes is not considered in this design in addition, in electricity consumption own, seldom generates electricity and there is no to consider the externally use of output power supply more in the situation that.
