Abstract

The utility model relates to an internal combustion concrete vibrator which belongs to the technical field of construction machine. The internal combustion concrete vibrator is especially suitable for concrete pavements. One end of a flexible shaft is connected with an output shaft of a fuel engine, the flexible shaft is penetrated through a guide pipe and a flexible pipe, the flexible shaft is inserted and connected with a rotating shaft by a tongue-shaped pin, a regulating type semi-circular eccentric block is arranged on the lower end of the rotating shaft, a lifting handle and a handle sleeve are arranged on the guide pipe, the guide pipe is connected with a vibrating head by a fixed rod, and the inclined angle of the shaft line of the rotating shaft and the plane of a vibrating plate is made less than 90 DEG.

Description

Internal combustion pendulum-type concrete vibrator

The utility model belongs to the building machinery field, is specially adapted to the rigid pavement.

Present domestic speedway development rapidly.The rigid pavement constantly enlarges, but builds the concrete surface vibrator of rigid pavement, is with electric motor driven, and the rotor axis of electric external part is equipped with eccentric block, produces vibration source.Motor is a horizontal machine, is installed on the base plate, when mobile is to move by the rotation or all around of motor, and time-consuming, the effort of operator is difficult for grasping.A fatal weakness is wherein arranged in the place that lacks power supply, need set up power supply, strengthened cost of investment, certain insecurity is arranged when using cable, electric wire.For easy to use at the non-transformer place, to grasp easily, safety operation just needs a kind of concrete surface vibrator of redesign.

The purpose of this utility model will design a kind of easy to use at the non-transformer place exactly, grasps the concrete surface vibrator of safety operation easily.

The technology that the utility model mainly adopts is: adopt oil-burning machine as power, the handle handle is arranged and the cover of shaking hands on conduit, angle is less than 90 ° between the axial line of turning cylinder and the plane of shimmy plate.

The utility model is compared with motor-driven concrete surface vibrator, following advantage is arranged: one, need not power supply, be suitable for field work; Two, because be the portable running mechanism that omitted, the scope of operation can be selected arbitrarily; Three, because be the pendulum-type vibration, concrete surface is easy to smooth.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is a structural representation of the present utility model, Fig. 2 be A to sectional view, Fig. 3 is the B-B sectional view.

Describe details of the present utility model and working condition in detail below in conjunction with Fig. 1,2,3.

One end of flexible axle (7) is connected with the output shaft of fuel engines (1), flexible axle (7) passes conduit (2) and flexible pipe (4), peg graft with ligulate pin (8) and turning cylinder (10), turning cylinder (10) is by bearing (9), (11) supporting, and the two semicircle eccentric blocks (12) of adjustment type are installed in the lower end of turning cylinder (10).Fuel engines (1) is by flexible axle (7), and turning cylinder (10) drives eccentric block (12) rotation, produces exciting force.On conduit (2), be equipped with handle (5) and the cover (14) of shaking hands.Since had the handle handle and shake hands the cover after, can be in any scope of operation operation.Between conduit (2) and shimmy head (13), there is fixed bar (3) to be connected, makes angle between the plane of the axial line of turning cylinder (10) and shimmy plate (6) less than 90 °.Because the angle between the plane of turning cylinder axial line and shimmy plate makes the power of shaking of the existing vertical ground of shimmy plate (6) less than 90 °, pendulum power about having again, these power were both tamped concrete, again the effect that can flatten.
