Description

A kind of road sanding apparatus for avoiding overheat from running

Technical field

The application is related to field of construction machinery, specially a kind of road sanding apparatus for avoiding overheat from running.

Background technology

In some job sites, such as road construction etc. generally requires to carry out roadbed basal plane local levelling, for example, need The local protrusion to be caused because of construction flaw to some is polished.

The flatness result of this polishing has a significant impact for follow-up road surface construction quality tool, such as road The occasion that face levelness tool has high requirements, such as highway are 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 equipment cost etc. because Element is often unsuitable.

The content of the invention

It is an object of the invention to provide the road sanding apparatus that overheat can be avoided to run, it can overcome of the prior art Drawbacks described above.

It is of the invention it is a kind of avoid overheat run road sanding apparatus, in road construction to construction road Local protrusion on face is polished, including external shell, motor and the grinding head drive-rod part that is driven by the motor, Wherein, the spline in drive sleeve portion of the motor by the spline rod that is fixedly connected and with the grinding head drive-rod part Hole and axially slidably power connection, the drive sleeve portion of the grinding head drive-rod part by tapered connecting portion with beat The grinding head of bistrique drive-rod part is installed bar portion and is fixedly connected, and the grinding head to be installed and be removably provided with polishing in bar portion Head, is provided with axially extending keys for the inner circumferential with the cylinder of external thread sleeve cartridge unit on the outer peripheral face in the drive sleeve portion Axis on wall extends keyway and coordinates, and the right part of the cylinder of the external thread sleeve cartridge unit is provided with end with being integrally formed Portion's ring is used to be removably secured with the shoulders in the drive sleeve portion by fastener and is connected, the external shell it is interior Portion is provided with the protuberance for extending internally in the radial direction so as to the cavity surrounded by the external shell be divided into left part Chamber and right part open wide cavity, and the endoporus in the protuberance is by the form of axially extending key and keyway and inner thread sleeve The cylindrical portion of part coordinates, and the end of the cylindrical portion of the inner screw sheath cartridge unit is provided with end flange with being integrally formed Portion is used to be removably secured with the annulus table top portion on the right side of the protuberance by fastener and is connected, wherein, the end The overall diameter of flange portion opens wide the interior diameter of cavity less than the right part, and the diameter of bore of the end loops is more than the grinding head The outline diameter of bar portion is installed, thus, the inner screw sheath cartridge unit can be dismantled and led to the external thread sleeve cartridge unit Above-mentioned right part is crossed to open wide cavity and can remove together；The right-hand member top of the external shell is fixedly installed the shield of semi-cylindrical Cover is used to form the receiving space for accommodating the grinding head, is provided with to show the water of levelness on the upside of the external shell The right-hand member of level device, the left end of the external shell and the shield is fixedly installed height adjustable legs device, institute respectively Stating height adjustable legs device includes leg housings, the height adjustment motor being fixedly installed in the leg housings inner chamber and institute In stating height adjusting screw rod that the rotor of height adjustment motor is fixedly connected and coordinating with the height adjusting screw rod screw thread Screw thread leg bar, the endoporus of the internal thread leg bar is provided with internal thread, be provided with outer peripheral face for the leg housings Key or keyway that inner chamber is slidably matched, the lower end of the internal thread leg bar are provided with plate-like foot and are used to be seated in construction road surface On；Crash roll is installed, the crash roll can prevent the motor in fortune between the inwall of the motor and the external shell Very big vibrations are produced during row, so as to influence precision of constructing；The fin of genesis analysis is installed on the motor outer surface, The louvre for radiating is provided with the external shell left side, being provided with the external shell below the motor makes sky The logical wind complement port of air-flow, produced heat is distributed by fin and louvre during the motor operation, prevents described Motor is for a long time in the running status of overheat.

By the present invention, due to using the right pressure of the screw-type produced when motor drives and rotates and simultaneously or synchronization rotation Turn such that it is able to drive polishing rotation and left and right translation that grinding head is synchronized, and simply use a motor, therefore knot Equipment cost is reduced when closing the polishing amount for local protrusion.Meanwhile, having used can be easy to screw thread to coordinate parafacies Close part is conveniently replaceable setting, can be required according to different polishing materials and polishing and be changed screw thread pair at any time, So as to adjust right pressure speed；On this basis, set external thread sleeve end aperture more than grinding head install shank diameter so as to The interference of mounting rod can not be received and removed unload to the right（Need only to unload grinding head and seal cover board）, together When, this set can increase the diameter of screw thread matching pair, reaction force when increasing polishing bear acting surface and alternatively with Increase lead or reduce lead angle.Meanwhile, the diameter of right-hand member flange of inner thread sleeve is set less than shell endoporus Diameter, ensure that the smooth removal of inner thread sleeve.Thereby, it is possible to external thread sleeve and inner thread sleeve are kept ordinatedly It is overall to remove, it is easy to dismount and safeguards.Increase the flexibility of equipment.And the leg that can utilize motor automatic controlled height is set Component, and with the use of level meter, can according to the physical plane profile on road surface the quick adjustment whole equipment in scene level Degree so that regulation is precisely so as to the processing flatness after the completion of ensure that polishing in polishing.Whole equipment is reliable, knot Structure is consolidated, and can reduce the overall cost of borehole.
