Abstract

The utility model is a vibrating rod used during construction, which comprises a shell, a vibrating ring, a vibrating hammer and a rod tail. The shell is internally provided with a stator, a rotor and a motor shaft; wherein, the motor shaft is provided with a commutator and a carbon brush at rear end and is connected with a drive wheel through a gear shifting mechanism with the front end; the drive wheel is connected with the vibrating hammer through a coupling. The utility model realizes that the 50 model vibrating rod is able to connect with electromotor directly and can work with single phrase power supply of 220V as well as enabling the vibrating hammer has biggest vibrating force to make the vibrating rod has strongest vibrating effect, thus improving the working efficiency, saving labor time and ensuring construction quality.

Description

Single-phase vibrating head

The utility model relates to a kind of mechanical vibrator, the vibrating head that uses in specifically a kind of building construction process.

Traditional vibrating head is made up of vibration caput and the outer motor two large divisions of rod, vibrate in the caput include housing, the ring that shakes, vibration hammer and excellent tail, in excellent tail sebific duct, flexible axle is housed, in order to motor outside the pitman and vibrating hammer.After connecting power supply, the motor rotation drives the vibration hammer starting of oscillation by flexible axle, shakes by the vibration hammer bump and encircles the vibration that realizes vibrating head.The greatest drawback that this vibrating head exists is exactly to carry and move very inconvenient at the construction field (site), and needs three phase mains to work.At present existing improved portable vibration rods, its design scheme are that motor is packed in the housing of vibrating head, directly drive vibration hammer starting of oscillation work by motor.Move the defective of inconvenience though this improvement project has overcome vibrating head, but have two shortcomings: the one, can only be applicable to the barred body diameter at the large size vibrating head more than 70 millimeters, for the vibrating head of 50 types, then too carefully can't realize because of diameter of the housing; The 2nd, because vibration hammer directly links to each other with motor, rotating speed is too high, and the exciting force of vibration hammer is greatly descended, and the effect of vibrating of vibrating head obviously reduces.

The purpose of this utility model just provides a kind of being particularly suitable for 50 type vibrating heads is carried out improved portable single-phase vibrating head, and to overcome the deficiency of existing vibrating head, the convenient construction operation is increased work efficiency.

The utility model is achieved in that single-phase vibrating head includes housing, the ring that shakes, vibration hammer and excellent tail, stator and rotor also are housed in housing, rotor center has motor shaft, commutator is equipped with in the rear end of motor shaft, the carbon brush that is fixed on the support is electrically connected with lead in the excellent tail, the front end of motor shaft connects driving wheel by gear, and driving wheel is connected with the rear end of vibration hammer by shaft coupling.

Design main points of the present utility model are: the one, stator, rotor and the motor shaft of motor directly is installed in the housing of vibrating head, so just can save greatly and take up room, make 50 type vibrating heads also can realize docking, made things convenient for constructing operation with the direct of motor.The 2nd, the structure member of direct current generators such as commutator, carbon brush is installed, make motor under 220 volts single phase poaer supply condition, get final product work, needn't 380 volts of three-phase alternating-current supplies of special configuration.The 3rd, between motor shaft and vibration hammer, install gear additional, make the vibration hammer rotating speed reduce to thousand rev/mins of 2.8-3 by 12,000 rev/mins high speed, thereby the operating characteristic that has adapted to vibration hammer, make it to produce maximum exciting force, vibrating head thereby reach the strongest effect of vibrating, can improve work efficiency thus, save man-hour, guarantee construction quality.

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing is a structural representation of the present utility model.

As shown in the figure, single-phase vibrating head includes housing 19, shake ring 1, vibration hammer 20 and excellent tail 21, and stator 8 and rotor 7 also are housed in housing, and rotor center has motor shaft 16, commutator 15 is equipped with in the rear end of motor shaft, and the carbon brush 14 that is fixed on the support 9 is electrically connected with lead 12 in the excellent tail 21.The front end of motor shaft 16 connects driving wheel 17 by gear 5, and driving wheel is connected by the rear end of shaft coupling 18 with vibration hammer 20.For adapting to the thin housing internal diameter of 50 type vibrating heads, preferably adopt stator 8 to be the form of structure of permanent magnet.The rear end of motor shaft 16 is supported on the support 9, and carbon brush 14 leans the both sides at commutator 15.On the terminal plate 10 that is anchored on support 9 rear end faces, be shaped on can with excellent tail lead 12 electrode in contact sheets 22, carbon brush has lead to be connected with 22 of electrode slices.The front end of rod tail lead 12 is fixing by insulating support 11, and the outer end is by lock tube 13 lockings.In the flexible rubber hose of excellent tail 21, just have only lead 12 like this, thereby can prolong arbitrarily and back order phase power supply, made things convenient for construction and carry.Rod tail 21 is when spinning with barred body, because the setting of electrode slice 22 on the terminal plate 10, has guaranteed that lead 12 is connected with good electrical between carbon brush for electric machine.

By accompanying drawing as seen, gear 5 is to be made of the two-stage speed changing transmission gear, and gear shaft is fixedly supported between the two

stands

4,6, and motor shaft 16 and driving wheel 17 are meshed with two-stage speed changing transmission gear in the gear respectively.In addition, support 6 also is supported on the front portion of motor shaft 16 simultaneously, and motor shaft 16 by the gear driven gear 5 on it, and finally drives driving wheel 17 and makes low speed rotation in the high speed rotary course.The leading section of driving wheel 17 is screwed on the shaft coupling 18 (being commonly called as " shaven head "), and shaft coupling 18 is connected vibration hammer 20 by steel ball 2 with snap ring 3, realizes the synchronous rotation of vibration hammer 20, shaft coupling 18 and driving wheel 17.Vibration hammer 20 clashes into the ring 1 that shakes after starting of oscillation, realize the work of vibrating of vibrating head.

In the accompanying drawing, housing 19 is to spin by four sections to combine, and is to design for ease of aggregate erection.The connected mode of shaft coupling 18 and vibration hammer 20 can keep the effective universal duty of vibration hammer, reaches good vibrating effect.Support 4 and support 6 cooperate with bearing, when playing the positioning supports effect, also have sealing function, prevent the oil leakage in the gear.
