Abstract

The utility model discloses a concrete vibrating spear which comprises a vibrating body, a combination switch and a plug, wherein the end portion of the vibrating body is a spear end and a sharp head connected with the spear end, and the spear end and the sharp head are used for being inserted into concrete. A middle body comprises an eccentric block, a stator and a rotor, the middle body rotates to drive the vibrating body to vibrate after being powered on, the middle body is connected with the tail through a connection pipe connected with a flexible pipe, and the flexible pipe is connected with the combination switch which is electrically connected with the plug. According to the concrete vibrating spear, a wave reed arranged inside a bearing fixing the eccentric block can reduce noise and vibration, and therefore vibration feel of the portion held by an operator through hands is small, the operator is not prone to being tired, the noise is low, operation is safer, the service life is long, and comprehensive cost is low.

Description

A kind of concrete vibration bar

Technical field

The utility model relates to a kind of vibrating head, and particularly a kind of concrete vibration bar, belong to mechanical technical field of buildings.

Background technology

When vibrating head is the concreting member that mixes for concrete agitator, must get rid of wherein bubble, make firm by ramming, make the concrete compaction combination, eliminate the phenomenons such as concrete voids and pits, to improve its intensity, guarantee the quality of concrete component.In existing technology, because concrete vibration bar adopts the flexible pipe transmitting torque more, and flexible pipe is subjected to the restriction of material etc., makes concrete vibrating head vibration force not reach requirement, can't be with the concrete tamping, perhaps, the shortcoming such as the concrete vibration bar noise is too large.

The utility model content

In order to address the above problem, the utility model provides a kind of concrete vibration bar, the noise in the time of can not only reducing this helper and do, and can greatly improve vibration force, tamped concrete effectively.

for achieving the above object, the technical solution adopted in the utility model is: a kind of concrete vibration bar, the involving vibrations body, stacked switch 16 and plug 17, described vibrating body is divided into the end, intermediate and afterbody three parts, described end is rod end 2 and the tip 1 that is attached thereto, in order to insert in concrete, described intermediate comprises eccentric block 6, stator 9 and rotor 10, produce after energising and rotate and vibrating body is vibrated, described eccentric block 6 is fixed on bearing 1, be equipped with ripple reed 3 in bearing 1, has the reduction noise, the function that reduces to vibrate, described stator 9 is by pin 7 stationary positioned, described rotor 10 is fixed on bearing 2 11, described intermediate is connected by tube connector 12 with afterbody, described tube connector 12 is connected with flexible pipe 14 by hose coupling 13, described flexible pipe 14 is connected with stacked switch 16 by tapered sleeve 15, described stacked switch 16 is electrically connected to plug 17.

There is setting of casing 5 aforesaid eccentric block 6 outsides.

There is upper sleeve pipe 8 aforesaid stator 9 outsides.

After having adopted technique scheme, the beneficial effect that the utility model compared with prior art has is: be provided with the ripple reed in the bearing of fixed eccentric block and have the reduction noise, the function that reduces to vibrate, make operating personnel's handgrip part vibration sense little, indefatigability, and noise is low, operation safe, long service life, integrated cost is low.

Description of drawings

Fig. 1 is the utility model concrete vibration bar structural representation.

The specific embodiment

Describe the utility model in detail below in conjunction with the drawings and specific embodiments.

as shown in Figure 1, concrete vibration bar of the present utility model, the involving vibrations body, stacked switch 16 and plug 17, described vibrating body is divided into the end, intermediate and afterbody three parts, described end is rod end 2 and the tip 1 that is attached thereto, in order to insert in concrete, described intermediate comprises eccentric block 6, stator 9 and rotor 10, produce after energising and rotate and vibrating body is vibrated, described eccentric block 6 is fixed on bearing 1, be equipped with ripple reed 3 in bearing 1, has the reduction noise, the function that reduces to vibrate, eccentric block 6 outsides also are provided with setting of casing 5, described stator 9 is by pin 7 stationary positioned, stator 9 outsides also are provided with sleeve pipe 8, described rotor 10 is fixed on bearing 2 11, described intermediate is connected by tube connector 12 with afterbody, described tube connector 12 is connected with flexible pipe 14 by hose coupling 13, described flexible pipe 14 is connected with stacked switch 16 by tapered sleeve 15, described stacked switch 16 is electrically connected to plug 17.

During work, after plug 17 switches on power, operative combination switch 16, electric current arrives stator through flexible pipe and the tube connector of the afterbody of vibrating body, produce rotating excitation field, thereby make rotor high-speed rotation, and drive the eccentric block that is attached thereto and rotate together, thus, make eccentric block produce eccentric force, under the effect of eccentric force, make whole vibrating body vibration, reach the purpose of tamped concrete.Because bearing one is interior, the ripple reed is set, therefore the noise when effectively having reduced vibration.

Abovely basic conception of the present utility model and basic principle have been set forth by better embodiment; but the utility model never is limited to above-mentioned listed embodiment; every equivalent variations or improvement of doing based on the technical solution of the utility model all should belong to protection domain of the present utility model.
