Abstract
The invention relates to an impact hammer with large hammer force. The impact hammer comprises a hammerhead component, a cantilever bar, a spring component, an eccentric mechanism and a deceleration driving device, wherein the upper end of the cantilever bar is hoisted in an outer package shell, the lower end of the cantilever bar is connected with the hammer component, so that the hammerhead component is in a suspension state in the outer package shell; the spring component is arranged in the inner cavity of the hammerhead component, the front end of the spring component is fixed with the hammerhead component, and the rear end of the spring component is connected with the eccentric mechanism and the deceleration driving device arranged in the outer package shell; the hammerhead component is driven to change the driving revolving speed of the hammerhead component through frequency conversion by the deceleration driving device and the eccentric mechanism, therefore, the spring component can obtain different vibrating frequencies during the sub-resonance period of the spring component, and generate axial displacement to drive the hammerhead component to produce different hammer forces and hammer speeds. The impact hammer with the large hammer force provided by the invention is simple in structure and low failure rate; furthermore, when the impact hammer and other equipments are compositely applied, the impact hammer and the other equipments can be integrated automatically and can be freely disconnected, therefore, the impact hammer can be applied to various occasions needed to be conducted for arch breaking in a material transportation system.
Description
Technical field
The invention belongs to the arch broken equipment of loose unpacked material, be specifically related to a kind of large hammer force ram hammer of one that solves viscous material and easily tie arch.A kind of large hammer force ram hammer of the present invention is applicable in the delivery system of the loose unpacked material that easily knot encircles such as thermal powerplant run coal bin, mine, harbour, harbour, silo, building materials.
Background technology
In process of production, the application of storage bin is very extensive, and the structural shape of storage bin is generally cement components or steel structure member.Because the long-term storage material in storage bin, particularly viscous material itself have larger bed of material pressure and internal friction.In course of conveying, be constantly attached on the sidewall of hopper, constantly thickening, forms knot doming effect, has affected the normal operation of equipment.
Existing anti-blocking, dredging mode is generally to adopt dredge or elastic hammering rapping apparatus, but dredge takes up room greatly, is difficult for adjustment, maintenance difficult.
No. 03261046.7 patent of invention provides a kind of elastic hammering rapping apparatus, by the transmission shaft of the output shaft connection for transmission mechanism of motor, on transmission shaft, cover has quill shaft, on quill shaft, be fixed with hammer body and pendulum interlinked mechanism, the pendulum interlinked mechanism of hammer body covers in protective cover, its pendulum interlinked mechanism is formed by a rotating shaft is hinged by large arm and forearm, one end of large arm is fixed on quill shaft by anchor ear, the forearm other end is equipped with three connecting traction wheels side by side, the connecting traction wheel of forearm end is corresponding with the connecting traction wheel of circular arc on hammer handle centre and forearm end, block is a plate with inclined-plane that is fixed on arc plate, arc plate is fixed on protective cover another side, have adjusting screw above, another side of connecting traction wheel is corresponding with the inclined-plane of block, protective cover inwall is attached with sound absorbing layer.
The shortcoming of this device is: the design of pendulum interlinked mechanism and guide plate and stop location and shape and structure is unreasonable, complex structure, be difficult for adjusting, rapping efficiency is lower, installation position is limited, can heterodyne, fault rate is high, broken arch mode is single.
Provide a kind of high-energy elastic impact rammer 2008 2 No. 0110093.3.Formed by shake spring, backup bearing, tup, hammering plate etc. of vibrating motor, connecting rod assembly, biography.When vibrating motor is started working, that compresses fixed end two passes the spring that shakes, reserve up and down.Promote the free-ended biography guide rail hammering hammering plate that spring, tup form along backup bearing that shakes simultaneously, carry out balance by connecting rod assembly and pass the suffered power of spring of shaking, guarantee the not Dutch roll of power of vibrating motor, do not tilt.Simultaneously hammering plate, to the biography spring opposite force that shakes, adds that upper and lower two groups pass the reverse elastic force that the spring that shakes discharges, and tup returns, and goes round and begins again.Motion produces high-energy arch-breaking power and so forth.Can be by pass the length of the spring that shakes in the middle of regulating for free end, the distance changing between tup and hammering plate regulates broken arch power.
The shortcoming of this device is: because spring is under high frequency tension and compression, there will be direction drift phenomenon, cause pivot shaft to bear hammering anti-force and very easily damage, break down; Another this device need to be installed three groups of springs, and cost of manufacture is high, and mounting process complexity, and when with other equipment Application of composite can not free off-the-line, sometimes adopts electromagnet structure to carry out off-the-line, but is subject to the restriction of the ranging coverage of electromagnet own, and off-the-line effect is undesirable.
Summary of the invention
