Abstract
The utility model aims at providing a pneumatic bituminous concrete vibrator which comprises a motor, a delivery pipe and a vibrating rod and is characterized in that the motor consists of an air pump and a pneumatic motor; the pneumatic motor is positioned in the vibrating rod; the delivery pipe is connected with the air pump and the vibrating rod; and a grab handle is arranged at the connecting part of the delivery pipe and the vibrating rod. The pneumatic bituminous concrete vibrator has the benefits that under the drive of the pneumatic motor, a spark is avoided, and accidents are reduced; since an earth wire is added, the probability of potential difference is reduced; since the grab handle is added, an operator is protected effectively, and the influence of vibration on people is reduced.
Description
Technical field
The utility model relates to the pavement construction technical field, relates in particular to a kind of wind-tunnel bituminous concrete vibrator.
Background technology
Bituminous concrete, English name: bituminous concrete, be commonly called as asphalt concrete, to there is the mineral aggregate (rubble or grating gravel, aggregate chips or sand, breeze etc.) and a certain proportion of bitumen for road use material of certain gradation composition, the compound that mixing forms under strict controlled condition through the artificial selection.
The intensity of bituminous mixture is mainly manifested in two aspects.The one, the adhesion stress of the cementitious matter that pitch and breeze form; Another is inner frictional resistance and lock knot power between aggregate particle.The huge surface area of breeze fine grained (mostly being less than 0.075 millimeter) makes bituminous material form film, thereby has improved adhesion strength and the temperature stability of bituminous material; Lock knot power mainly produces between the coarse aggregate particle.To take into account both while selecting the bituminous concrete mineral aggregate gradation, with reach add after appropriate pitch compound can form closely knit, stable, roughness is suitable, long-lived road surface.Coordinate mineral aggregate that several different methods is arranged, can calculate with formula, also specified grading scope by rule of thumb, China adopts the grading limit of experience curve at present.Pitch Optimum in bituminous mixture, should determine with the practical situation in laboratory test result and building site, generally in relevant specification, all shows the guidance that the asphalt content scope that provides a reference is joined as examination.When mineral aggregate kind, grading limit, bitumen consistency and kind, mix and stir facility, local climate and traffic characteristic fixedly the time, also can adopt the empirical formula estimation.
Bituminous concrete vibrator (electric concrete vibrator), make the closely knit electric tools of fluid concrete by vibration.Have concrete vibrator in prior art, but mostly these concrete vibrators are that motor drives or fuel oil drives, and lack corresponding earth leakage protective device, in the process of construction, because there is certain potential safety hazard in the combustibility of pitch.
The utility model content
Problem to be solved in the utility model is: a kind of pneumatic bituminous concrete vibrator is provided.
The technical solution of the utility model is as follows: a kind of pneumatic bituminous concrete vibrator, comprise motor, carrier pipe and vibrating head, it is characterized in that: described motor is become with pneumatic groups of motors by air pump, and described air motor is positioned at vibrating head, and described carrier pipe connects air pump and vibrating head; The junction of described carrier pipe and vibrating head is provided with lever.
Further, the high pressure black rubber pipe that described carrier pipe is steel wire winding.
Further, described lever is provided with anti-slip veins.
Further, described vibrating head is metal material.
The beneficial effects of the utility model are: by the pneumatic bituminous concrete vibrator of the utility model, under the drive of air motor, avoided occurring the situation of spark, reduced accident; The increase of ground wire, reduced the possibility that electrical potential difference occurs; The increase of lever, effectively protected operating personnel, reduces the impact of vibrations on the people.
The accompanying drawing explanation
Fig. 1 is the structural representation of this use confidence.
Wherein: 1, air pump, 2, carrier pipe,
3, vibrating head, 4, air motor,
5, lever.
The specific embodiment
Below in conjunction with accompanying drawing, concrete enforcement of the present utility model is made to brief description.
As shown in Figure 1, a kind of pneumatic bituminous concrete vibrator, comprise carrier pipe 2 that the high pressure black rubber pipe of motor, steel wire winding is made and the vibrating head 3 of metal material, described motor is comprised of air pump 1 and air motor 4, described air motor 4 is positioned at vibrating head 3, and described carrier pipe 2 connects air pump 1 and vibrating head 3; The junction of described carrier pipe 2 and vibrating head 3 is provided with lever 5, and described lever 5 is provided with anti-slip veins.
Working method: booster air pump 1, gases at high pressure are delivered to air motor 4 along carrier pipe 2, and air motor 4 drives vibrating head 3 vibrations.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
