The excavator is excellent in usability and unique in function, and the pressure sensing device additionally arranged at the joint of the bucket connector and the movable arm is capable of effectively monitoring borne elasticity of the bucket during excavation and is capable of giving warning prompt timely when the elasticity of materials acting on the bucket is excessive, so that damage to the bucket and hydraulic elements is avoided, and excavation operations are guaranteed to be carried out normally.
Description
Technical field
The present invention relates to a kind of excavator, relate in particular to the novel excavator that has overload protection function in a kind of mining process, belong to the excavator technical field.
Background technology
Excavator claims excavation machinery again, is to excavate with scraper bowl to be higher or lower than the material that holds machine side, and the haulage vehicle or unload earth moving plant to rickyard of packing into.The material that excavator excavates mainly is soil and the rock behind soil, coal, silt and the pre-pine of process.From the development of engineering machinery in recent years, the development of excavator is very fast relatively, and excavator has become one of topmost engineering machinery in the engineering construction.
In the mining process of excavator, because scraper bowl directly contacts with material, therefore, wear extent is very big; Simultaneously, material can feed back to Hydraulic Elements by connector to the elastic force of scraper bowl, if elastic force is excessive, causes the excessive loss of Hydraulic Elements easily, scraps in advance.In mining process, the time regular meeting run into some ratchels or building waste, particularly building waste, if orcible entry is not exclusively, under the effect that involves of reinforcing bar, form large-scale material piece easily.At this moment, scraper bowl can not disposablely be finished dredge operation, if proceed dredge operation, material can be very big to the elastic force of scraper bowl, and scraper bowl weares and teares easily; Simultaneously, the elastic force that exceeds standard causes the damage of Hydraulic Elements easily, and excavator has to suspend maintenance, has improved the frequency of maintenance, even delays the progress of engineering.
Summary of the invention
At the demand, the invention provides a kind of excavator, this excavator has been set up the pressure sensitive device between scraper bowl connector and swing arm, this device can effectively be monitored the bearing capacity on the scraper bowl in the mining process, when material exceeds standard to the elastic force of scraper bowl, the damage of scraper bowl and Hydraulic Elements is avoided in the prompting that can in time give the alarm, and has improved the application life of dredge operation.
The present invention is a kind of excavator, this excavator comprises lower running body, top revolving body and front end equipment, described front end equipment is made up of dipper assembly, movable arm-set and bucket assembly, described bucket assembly is made up of scraper bowl and scraper bowl connector, described scraper bowl connector is made up of upper arm and underarm, both adopt hinge to connect, the other end of described upper arm connects swing arm, the other end of underarm connects scraper bowl, connected mode all adopts hinge to connect, and a pressure sensitive device is set up in described upper arm and swing arm junction.
In a preferred embodiment of the present invention, described pressure sensitive device is installed between the rocker bar bearing and swing arm surface of upper arm ends.
In a preferred embodiment of the present invention, described pressure sensitive device is made up of hydrostatic sensor, wireless launcher, singlechip chip, battery, shell body and interlock circuit.
In a preferred embodiment of the present invention, the described wireless launcher radio receiver interior with being arranged on the driver's cabin control panel docks.
In a preferred embodiment of the present invention, described radio receiver is made up of wireless receiver, data processor, autoalarm and interlock circuit.
In a preferred embodiment of the present invention, described data processor is handled supporting power, in case the supporting power overload, autoalarm sends the buzzing prompt tone.
In a preferred embodiment of the present invention, the limiting value of described supporting power can set in advance, and this value is by length and the actual supporting power conversion gained of upper arm, underarm.
The present invention has disclosed a kind of excavator, this excavator functional performance is good, the function uniqueness, set up the pressure sensitive device at scraper bowl connector and swing arm junction, this device can effectively be monitored the suffered elastic force of scraper bowl in mining process, and when material exceeded standard to the elastic force of scraper bowl, prompting can in time give the alarm, avoid the damage of scraper bowl and Hydraulic Elements, guaranteed normally carrying out of dredge operation.
