The novel multifunctional frequency and amplitude modulating vibration hammer modulates frequency by a gear-changing method, and meantime, an eccentric block is divided into a fixed eccentric block component and an adjustable eccentric block. The adjustable eccentric block is conveniently regulated to change the amplitude of the vibration hammer, and a full-steel bar cage can be also arranged to match the heavy tamping of a gravity hammer. The utility model used as a new vibration hammer saves time in adjustment with convenience, and has powerful function and excellent cost performance ratio.
Description
The utility model belongs to piling machinery.
Hole making by vibration stake machine has obtained development rapidly in recent years, and vibrating hammer is the heart component of hole making by vibration stake machine, and the quality of its performance will directly influence the result of use of a machine.The vibrating hammer of people's use at present mainly contains following several: common set hammer, second belt frequency modulation hammer, amplitude variable hammer, suspension type hammer or the like.Though these vibrating hammers all have himself characteristics and advantage, up to this point, still without any a kind of comprehensive hammer, it can frequency modulation, again can amplitude modulation, and easy to adjust saving time.Because various soil properties respectively have its natural frequency and hardness, and unit in charge of construction generally can not buy the hammer of multiple model, so hole making by vibration stake machine has been subjected to certain restriction in the use.
The purpose of this utility model is to overcome the common defects of existing various vibrating hammers, provide a kind of can frequency modulation, again can amplitude modulation, and the comprehensive vibrating hammer in timesaving easy to adjust.
Main points of the present utility model are:
1, motor is connected with change gear by fast-assembling pin shaft coupling, change gear has the different refill-unit of some numbers of teeth, change gear and idler gear are meshing with each other, idler gear is installed in the gear-box, some axis holes that are used to install idler gear to designing according to change gear and the refill-unit number of teeth thereof are arranged on the gear-box, idler gear is meshing with each other with a gear wheel again simultaneously, this gear wheel is meshing with each other with another gear wheel again, the gear shaft of these two gear wheels is respectively by two relative revolutions of main shaft of key and two fixedly connected drives of main shaft, like this, change by changing the change gear and the number of teeth thereof, and mobile simultaneously idler gear position is meshing with each other itself and change gear and gear wheel, can change the speed of gyration of two main shafts, be changed with regard to the vibration frequency that makes vibrating hammer like this and reached the purpose of frequency modulation.
2, (q.r is an eccentric moment in the formula, and Q is vibrating hammer and stake pipe gross weight, and A is the vibrating hammer amplitude according to formula A=(qr)/(Q).) as can be known,, can adjust amplitude as long as change eccentric moment.For this reason, the utility model makes the fixed eccentric block assembly separate with the adjustable eccentric piece, all is provided with the adjustable eccentric piece at the two ends of two main shafts, regulates eccentric moment by regulating the amplitude modulation bolt, thereby has reached the purpose of amplitude modulation.
Following accompanying drawing provides an embodiment of the present utility model.

The embodiment that provides below in conjunction with accompanying drawing does detailed description to the utility model:
A kind of FMAM vibrating hammer, involving vibrations hammer body (13), motor (1), main shaft (10a, 10b), fixed eccentric block assembly several parts such as (11), hammer body top and motor (1) are connected with shock-absorbing spring (20), peen portion is symmetrically installed with sash weight sister block (21), the hammer bottom is equipped with pressurization single-sheaved block (22), the hammer body side is equipped with two groups of directive wheels (6) so that vibrating hammer moves up and down along the tappet guide rail, motor of the present utility model (1) is connected with change gear (3) by fast-assembling pin shaft coupling (2), change gear (3) has some the refill-units that the number of teeth is different, change gear (3) is installed in the gear-box (4), the change gear and the refill-unit thereof of three kinds of different numbers of teeth have been designed among the embodiment of the present utility model altogether, for making change gear (3) and gear wheel (8a, 8b) mutual cooperation, the utility model is at change gear (3) and gear wheel (8a, 8b) is provided with an idler gear (5) between, change gear (3) is meshing with each other with idler gear (5), idler gear (5) is installed in the gear-box (4), some axis holes that are used to install idler gear (5) (7) to designing according to change gear (3) and the refill-unit number of teeth thereof are arranged on the gear-box (4), have the change gear of respectively corresponding three the different numbers of teeth of three pairs of axis holes among the embodiment of the present utility model, if change change gear (3) like this, as long as correspondingly adjust the installation axle hole of idler gear (5) idler gear (5) both was meshing with each other with change gear (3), be meshing with each other with gear wheel (8a) again, idler gear (5) is meshing with each other with gear wheel (8a), gear wheel (8a) is meshing with each other with gear wheel (8b), gear wheel (8a, 8b) gear shaft is respectively by key (9) and two main shaft (10a, 10b) fixedly connected, gear wheel (8a, 8b) can drive two main shaft (10a like this, 10b) along opposite direction revolution.
Be separately installed with fixed eccentric block assembly (11) on the main shaft of the present utility model (10a, 10b), main shaft (10a, 10b) adjustable eccentric piece (12) all is equipped with at two ends, have four amplitude modulation aperture (14) on vibration hammer body (13) sidewall and adjustable eccentric piece (12) relative position, four amplitude modulation are sealed by four cover plates (15) respectively with aperture (14), and adjustable eccentric piece (12) is regulated respectively by four amplitude modulation bolts (16).Can change eccentric moment as long as adjust adjustable eccentric piece (12) like this, thereby change the vibrating hammer amplitude.
Frequency modulation of the present utility model, amplitude modulation principle are as follows:
When needs frequency modulation, pull down fast-assembling pin shaft coupling (2), change change gear (3), and adjust the installation axle hole (7) of idler gear (5) simultaneously, at this moment because the change gear number of teeth changes, the transmission speed ratio of change gear and idler gear also changes, two gear wheel (8a, 8b) rotating speed changes, and causes the speed of gyration of two main shafts to change, thereby vibration frequency is changed.
When wanting amplitude modulation, open cover plate (15), unscrew amplitude modulation bolt (16), change adjustable eccentric piece (12) to desired location, screw the amplitude modulation bolt adjustable eccentric piece is reorientated, cover cover plate, at this moment because the change of adjustable eccentric piece position, eccentric moment is also changed, so the vibrating hammer amplitude also adjusted, and exciting force also obtains changing.
For making the many usefulness of vibrating hammer one hammer, the utility model can be opened one in hammer body central authorities can be improved circular hole (17) intensity at circular hole (17) the edge fixedly connected some reinforcing ribs in the outside (18) in order to the circular hole (17) that discharges full reinforcing cage simultaneously.
Hammer body central circular hole (17) top can supporting one covers circular hole (17) only in order to cooperate the strong pile cover (19) that rams of weight.
The utility model not only Frequency Adjustable but also width-adjustable, and easy to adjust saving time, general frequency modulation or amplitude modulation did not all need to finish in one hour, full steel reinforcement cage can be discharged simultaneously and the weight strong rammer can be cooperated, therefore result of use is good, is that a kind of function is stronger, the novel vibrating hammer that performance and price is more excellent.
