A kind of road construction device of noise reduction
Technical field
The application is related to field of construction machinery, the road construction device of specially a kind of noise reduction.
Background technology
In some job sites, such as road construction etc., generally require roadbed basal plane is carried out that local is levelling, for example, need the local that some are caused because of construction flaw to protrude and polish.
The flatness result of this polishing has a significant impact for follow-up road surface construction quality tool, the occasion for example having high requirements for road level degree tool, and such as highway is especially high for this requirement for horizontality.Simultaneously as this detail sanding actually material removal amount is frequently not very big, therefore, traditional grinding machine due to be related to the factors such as equipment cost often unsuitable for.
Content of the invention
It is an object of the invention to provide the road construction device of noise reduction, it can overcome drawbacks described above of the prior art.
A kind of road construction device of the noise reduction according to the present invention,Polish for protruding to the local on construction road surface in road construction,Including external shell、Motor and the grinding head drive-rod part being driven by described motor,Wherein,By the spline rod that is fixedly connected and with the splined hole in the drive sleeve portion of described grinding head drive-rod part and axially slidably power couples described motor,The drive sleeve portion of described grinding head drive-rod part installs bar portion by tapered connecting portion with the grinding head of grinding head drive-rod part and is fixedly connected,Described grinding head is installed and is removably provided with grinding head in bar portion,Axially extending keys is provided with the outer peripheral face in described drive sleeve portion for extending keyway cooperation with the axis on the internal perisporium of the cylinder of external thread sleeve cartridge unit,The right part of the described cylinder of described external thread sleeve cartridge unit is provided with end loops and is connected in order to be removably secured with the shoulders in described drive sleeve portion by securing member with being integrally formed,Described external shell be internally provided with the protuberance extending internally in the radial direction thus left part inner chamber and right part will be divided into by the cavity that described external shell is surrounded to open wide cavity,The cylindrical portion cooperation with inner screw sheath cartridge unit by the form of axially extended key and keyway of endoporus in described protuberance,The end of the described cylindrical portion of described inner screw sheath cartridge unit is provided with end flange portion with being integrally formed,Described end flange portion is connected in order to be removably secured with the annulus table top portion on the right side of described protuberance by securing member,Wherein,The overall diameter in described end flange portion is less than the interior diameter that described right part opens wide cavity,The diameter of bore of described end loops is more than the outline diameter that described grinding head installs bar portion,Thus,Described inner screw sheath cartridge unit and described external thread sleeve cartridge unit can dismantle and cavity is opened wide by above-mentioned right part and can together with remove;It is fixedly installed semi-cylindrical guard shield in order to form the receiving space accommodating described grinding head above the right-hand member of described external shell,The upside of described external shell is provided with to show the level instrument device of levelness,The right-hand member of the left end of described external shell and described guard shield is fixedly installed altitude mixture control leg device respectively,Described altitude mixture control leg device includes leg housings、It is fixedly installed on the height adjustment motor in described leg housings inner chamber、The height adjusting screw rod being fixedly connected with the rotor of described height adjustment motor and the female thread lower limb bar with the cooperation of described height adjusting screw rod screw thread,The endoporus of described female thread lower limb bar is provided with female thread,The structure of the key being slidably matched for the inner chamber with described leg housings or keyway is provided with outer peripheral face,The lower end of described female thread lower limb bar is provided with plate-like foot in order to be seated on construction road surface,Described motor outer surface is coated with to reduce the silencing cotton ring producing noise during described motor operation,Described silencing cotton ring outer surface is connected with described external shell medial wall,Described silencing cotton ring inner surface is fixedly connected with described motor outer surface.
By the present invention, due to using the right pressure of the screw-type that produces when motor drives and rotates and simultaneously or synchronization rotation, so as to drive the polishing rotation that grinding head synchronizes and left and right translation, and simply use a motor, therefore combine during the polishing amount for local protrusion and decrease equipment cost.Meanwhile, employ can be easy to screw thread matching pair associated components be conveniently replaceable setting, can require and be changed screw thread pair at any time according to different polishing materials and polishing, thus adjusting right pressure speed;On this basis, the end aperture of setting external thread sleeve is more than grinding head installation shank diameter and removes to the right and unload so as to not be subject to the interference of mounting rod(Need only to unload grinding head and seal cover board), meanwhile, this set can increase the diameter of screw thread matching pair, increase counteracting force during polishing and bear acting surface and alternatively to increase lead or to reduce lead angle.Meanwhile, the diameter of the right-hand member flange of setting inner thread sleeve is less than the diameter of shell endoporus, ensure that smoothly removing of inner thread sleeve.Remove thereby, it is possible to external thread sleeve and inner thread sleeve are kept ordinatedly overall, be easy to dismount and safeguard.Increase the flexibility of equipment.And the leg member that can utilize motor automatic controlled height is set, and use cooperatively level indicator, the levelness of whole equipment can quickly be adjusted so that adjusting precisely thus ensure that the processing flatness after the completion of polishing in polishing in scene according to the physical plane profile on road surface.Whole equipment is reliable, stabilized structure, can reduce the overall cost of borehole.
Brief description
Fig. 1 is the overall structure diagram of the road construction device of the noise reduction of the present invention.
Specific embodiment
With reference to Fig. 1, the present invention is described in detail.
