Description
Technical field:
The utility model relates to engineering machinery, a kind of pile hammer of more specifically saying so.
The piling machinery that uses on the building site at present has diesel pile hammer, vibrohammer and static pile press, and wherein diesel pile hammer is used the impact force principle, compares with static pile press with vibrohammer to have tangible advantage, thereby is widely adopted.Diesel pile hammer is divided into two kinds of guide rod type and cartridge types by its action feature.The cartridge type driving energy is big, and the efficiency of construction height is present most widely used a kind of pile driving equipment.
Though diesel pile hammer is extensive use of, but still exists following significant drawbacks to have much room for improvement:
1, because diesel pile hammer adopts impingement Diesel engine principle to make, must adopt suspension hook earlier impact body to be risen to certain altitude, could start diesel pile hammer.Therefore, make diesel hammer structure more complicated.
2, because diesel pile hammer adopts two-stroke diesel explosive motor principle to make, diesel oil explosion type burning in cylinder can produce very big noise, seriously disturbs the surrounding area; Diesel oil burns insufficient in cylinder, thereby the waste gas of discharging can seriously pollute surrounding environment.
If the soil layer of 3 piling is softer, when falling, tup in cylinder, can not produce enough pressure, and diesel pile hammer can not normally start and move, thereby, smaller to the accommodation of soil layer.
Summary of the invention:
The utility model is for solving above-mentioned existing in prior technology problem, provides a kind of and does not produce noise and exhaust emission, can be widely used in various soil properties, do not need to have disposed the environment-friendly type electromagnetic hammer of sash weight application specific architecture.
The technical scheme that the utility model technical solution problem is adopted is:
Design feature of the present utility model is that the Electromagnetic Drive structure is set, described Electromagnetic Drive structure is the cover tubular coil of vertical direction setting by axis and the magnetic conduction impact body that slides in the sleeve of coil constitutes, wherein, described coil is arranged in the discharge loop of the pulse power, coil adopts hollow copper conductor to twine, the hollow cavity of hollow copper conductor is the cooling water circulation canal, the coil periphery is provided with yoke, the bottom of coil emits with stake by yoke and connects firmly, stake emit and pile body between pressure sensor is set, the top of coil is provided with guide cylinder, and the impact body position sensor is set on guide cylinder.
The utility model is to drive impact body with the electromagnetic force that the electromagnetism driving principle produces, and promotes its vertical height, makes it have enough potential energy.When the impact body that is thus lifted to certain altitude fell, the potential energy of impact body changed the kinetic energy that moves downward into.When falling back to the effective range of the electromagnetic driver of being made up of coil and yoke under the impact body, electromagnetic driver produces electromagnetic force once more and stops impact body to fall, and it is upspring again.The kinetic energy and the potential energy that has of being upspring again that impact body falls react on electromagnetic driver, make driving implement that the impact force of downward motion be arranged, and this impact force is emitted through stake and affacted in the stake, and impact stake sinks.Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is to drive impact body with electromagnetic force, thereby has not both had toxic emission, does not also have the noise of cylinder detonation, embodies its important environmental-protecting performance.
2, in the utility model, between impact body and coil for being slidingly matched, compare with being sealed and matched between the upper piston of tubular diesel pile hammer and the cylinder, the utility model is much lower to the requirement on machining accuracy that these two parts cooperate, and has also eliminated the friction energy loss that produces owing to being sealed and matched.
3, the coil in the utility model adopts hollow copper conductor to twine, and the hollow cavity of hollow copper conductor is the cooling water circulation canal.The setting of cooling system has reduced the diameter and the weight of coil significantly, has reduced operating voltage, is that the utility model can drop into practical application, protection coil not because of the overheated important assurance that damages.
4, the utility model need not to have disposed the sash weight special equipment, thereby also simplifies the structure, reduced equipment investment.
5, the utility model can make the pulse power provide operating current for coil exactly in the impact body motion process on the one hand according to the output signal of position sensor; The driving force that can regulate the impact body by the width and the amplitude of control impuls electric power outputting current on the other hand; Moreover, can also adjust the running parameter of the pulse power according to the pressure signal that pressure sensor obtains, thereby in time change piling strength according to the difference of soil property.
