Abstract
The utility model relates to a variable-frequency resonance-free electric drive vibration pile hammer. A drive motor in a driving mechanism adopts a variable-frequency vibration-resistant motor, and an eccentric shaft assembly comprises a plurality of eccentric shafts which are sequentially matched and connected. The first eccentric shaft of the eccentric shaft assembly near the end part is a power input shaft, and other eccentric shafts are power output shafts. Gear wheels are fixedly arranged on the rear end parts of the power input shaft and the power output shafts, eccentric blocks are arranged on the middle positions, and a belt wheel is arranged on the shaft end of the power input shaft. The variable-frequency resonance-free electric drive vibration pile hammer has the beneficial effects that the structure is novel, and the frequency of the vibration pile hammer can be regulated; and when the vibration pile hammer is started and stopped, the vibration pile hammer utilizes a frequency converter and an energy transducer to quickly pass through a resonance region, and resonance is avoided. By the regulation for the frequency of the vibration pile hammer, the speed of driving and extracting piles is quickened, and the use range of the vibration pile hammer is expanded. The reliable performance of the whole vibration pile hammer is increased, the requirements for allowable lifting weight of corollary equipment of vibration pile driving are reduced, and the capacity of the power supply is reduced.
Description
[technical field]
The utility model relates to the piling machinery equipment technical field, and specifically a kind of frequency conversion electricity of exempting to resonate drives vibrohammer, is widely used in foundation constructions such as harbour, wind-powered electricity generation, building machinery, is a kind of visual plant of pile foundation construction.
[background technology]
Existing pile foundation construction equipment mainly contains Static pressure pile driver, diesel hammer, common vibrating hammer etc.Wherein, Static pressure pile driver is unfavorable for transportation and construction owing to volume, weight are bigger; And the diesel hammer noise is big, and is seriously polluted, also has certain limitation; Common vibrohammer produces resonance harm owing to frequency is unadjustable, surrounding buildings and crowd are caused harmful effect.
[summary of the invention]
The purpose of this utility model is exactly to solve above-mentioned deficiency, and provides a kind of frequency conversion electricity of exempting to resonate to drive vibrohammer.The Motor Drive type Frequency Adjustable that is a kind of vibrohammer frequency adjustable, exempts to resonate is exempted from resonant vibrohammer.Because of vibrohammer frequency adjustable joint, thereby avoid producing covibration.
Design a kind of frequency conversion electricity of exempting to resonate for achieving the above object and drive vibrohammer, include power-driven mechanism 1, eccentric shaft assembly 2, drive motors 21 in the described driving mechanism 1 adopts the anti-motor that shakes of frequency conversion, described eccentric shaft assembly 2 comprises a plurality of eccentric shafts, be connected successively between the described eccentric shaft, described eccentric shaft assembly 2 is a power input shaft near first eccentric shaft of end, eccentric shaft is power output shaft in addition, described power input shaft, be set with gear on the rearward end of power output shaft, the centre position is provided with eccentric block, and described power input shaft axle head is provided with belt pulley.
Described eccentric shaft assembly 2 includes the first eccentric shaft A3, the second eccentric shaft B4, the 3rd eccentric shaft C5 and the 4th eccentric shaft D6, the described first eccentric shaft A3 is a power input shaft, be set with gear A 8 on the rearward end of described power input shaft, the centre position is provided with eccentric block A7, is respectively arranged with on the forward and backward axle head to be subjected to driving force belt pulley A9 and belt pulley B16; The described second eccentric shaft B4, the 3rd eccentric shaft C5 and the 4th eccentric shaft D6 are power output shaft, all be set with gear B 10, gear C 11 and gear D 12 on the rearward end of described power output shaft, be set with eccentric block B13, eccentric block C14 and eccentric block D15 on the centre position.
The described electricity of exempting to resonate drives the vibrohammer technical scheme, by adopting programmable logic controller (PLC) (PLC) frequency converter is realized logic control, and cooperate energy conversion device to realize passing through fast the vibrohammer resonance region, realize the vibrohammer frequency adjustable, exempt from resonance and motor soft start function.Specific implementation is divided into three mode of operations:
1. when vibrohammer starts,, the incoming frequency and the electric current of the anti-motor that shakes of frequency conversion are increased gradually, realize the soft start of vibrating hammer with programmable logic controller (PLC) control frequency converter.
2. when vibrohammer is worked, can regulate and control within the specific limits the operating frequency of vibrating hammer, better adapt to the pile vibrosinking needs of different soil properties by programmable logic controller.
3. when vibrohammer stops, with programmable logic controller (PLC) control frequency converter, anti-motor incoming frequency and the electric current of shaking of frequency conversion reduced gradually, this moment because of the synchronous rotational speed of motor less than rotor speed, motor transfers generating state to by motor, and torque becomes the formulation torque.Open energy conversion device simultaneously and absorb the regenerative electric energy that motor that vibrating hammer is in generating state because of running inertia drags produces, pass through the vibrohammer interval of resonance fast, realize the resonance of exempting from of vibrohammer to reach.
The utility model is compared with prior art, novel structure, simple, and easy to use, its vibrohammer frequency can be regulated, and vibrohammer starts, utilizes frequency converter and energy converter to pass through resonance region fast when shutting down, and avoids the generation of resonating.By the adjusting of vibrohammer frequency, accelerate heavy pile pulling speed, enlarge the vibrohammer scope of application.Increase vibrohammer whole aircraft reliability energy, reduce requirement, reduce capacity power supply to the hoisting weight allowable of pile vibrosinking corollary equipment.In addition, the utility model is easy to make, and cost is low, is worthy of popularization.
