Description
Technical field
The utility model is the electric harmonic reciprocating line motion impact device that a kind of electric energy directly acts on linear reciprocating motion.
Background technology
At modern mining, Rail Highway is built, water conservancy construction, in the engineerings such as building and installation, carry out rock drill and bore the Loose Blasting hole, ore smashes, foundation stabilization piling, concrete vibrating is closely knit, body of wall is punchinged, field riveting and nailing, feed bin and chute jarring are anti-blocking, construction operations such as steel surface jarring rust cleaning, be extensive use of the various impact devices and the utensil that utilize reciprocating motion to impact work done, include rock drill, percussive drill, the vibratory impulse pile monkey, jump bit, vibrator and various hand-held impact utensils etc., its core component are the reciprocating mechanisms that impacts work done.That the reciprocating power of present impact device has is pneumatic, hydraulic pressure, internal combustion and electronic several.Pneumatic, hydraulic pressure and internal combustion impact device all are piston types, the operation principle of piston type impact device has determined it must be equipped with special dynamical system or the hydraulic power system of calming the anger could to work, be the electric power epoch now, the dynamical system of calming the anger and hydraulic power system mostly are that electric power is carried out the secondary conversion, again by the fluid transmission.Fluid transmission energy loss is big, particularly in mining, pneumatic rock drilling equipment air feed distance is generally distant, the compressed air line that has reaches km, gas leakage and pipe resistance energy loss are very big, add problems such as equipment work efficient and no-load running, the Integrated Energy efficient of mine pneumatic rock drilling system is very low, for example in many mines, an average ballistic work is that 60 joules, frequency of impact are 30 hertz air drill, the air compressor of supporting power needs 22 kilowatts, and the Integrated Energy efficient of pneumatic rock drilling system is less than 10%.In addition, pneumatic rock drilling system equipment and facility are huge, and it is big to make installation steel consumption amount, and investment and operation and maintenance cost are big, and also there are safety in production problems such as vibration, noise and pressure vessel in the air compression station of the dynamical system of calming the anger.Internal combustion piston type impact device be on the piling machine and on the gadding machine internal-combustion piston engine directly as impact device, when piston is done stroke movement, directly do impact work, it has tail gas pollution, noise, volume greatly with from problems such as carrying fuels.It is that frequency of impact is high more, energy efficiency is low more that the piston type impact device also has a shortcoming, frequency of impact is an important performance of impact device, for example punching on the hard rock in many occasions, ground piling and concrete vibrating are closely knit etc. in the operation, improve frequency of impact and can increase work efficiency.Electric impacting equipment directly uses power supply, power is single, easy to use, do not need power to be carried out the secondary conversion with supporting special equipment, but present electric impacting equipment all is motor-type, all be motor to be rotatablely moved become linear reciprocating motion and carry out impact work, the speed that becomes linear reciprocating motion that rotatablely moves is the sine curve characteristic, the second half section of motion is to slow down until being zero, do not meet the requirement of impact work, need the linear reciprocating motion of sine curve characteristic to be transformed into linear reciprocating motion freely by special transmission mechanism, structure is complicated, consumable accessory is more, but also has increased energy loss, has restricted the development and the application of present motor-type impact device.
At present, though pneumatic and hydraulic piston type impact device Integrated Energy efficient is very low, technology maturation does not also have the advanced product that can substitute at present, and pneumatic and hydraulic impact equipment are the leading equipment in the impact device always.Particularly in mine construction and exploitation, pneumatic rock drilling equipment uses the widest, quantity is maximum, the dynamical system of calming the anger in the mine is the large electricity consumer always, conservative estimation, 300,000 ballistic works are arranged is 60 joules by using altogether in national mine, frequency of impact is 30 hertz air drill conversion, the mine generate output that dynamical system needs of calming the anger will reach 6,600,000 kilowatts, need to consume a large amount of energy, but also to consume a large amount of steel, producing steel also is major power consumer, now in the world still based on coal and oil generating, coal and oil are non-renewable resources, now coal and petroleum resources reduce the contradiction that increases with energy demand and exceed and be becoming tight, and coal and oil generating environmental pollution and climate warming influence are serious, therefore improve the energy efficiency of impact device, saves energy is global big problem.
