Description

A kind of road construction device with limit function

Technical field

The application is related to field of construction machinery, specially a kind of road construction device with limit function.

Background technology

In some job sites, such as road construction etc., it is levelling to generally require to carry out roadbed basal plane local, for example, need Protrude and polish in the local some are caused because of construction flaw.

The flatness result of this polishing has a significant impact for follow-up road surface construction quality tool, such as road The occasion that levelness tool in face has high requirements, such as highway, for this requirement for horizontality especially high.Simultaneously as this Detail sanding actually material removal amount be frequently not very big, therefore, traditional grinding machine due to be related to equipment cost etc. because Element often unsuitable for.

Content of the invention

It is an object of the invention to provide the road construction device with limit function, which can overcome of the prior art above-mentioned Defect.

According to the present invention a kind of road construction device with limit function, in road construction to construct road surface Local protrude polished, the grinding head drive-rod part driven including external shell, motor and by the motor, its In, the motor is by the spline hole axle in the spline rod that is fixedly connected and the drive sleeve portion of the grinding head drive-rod part Couple to slidably power, the drive sleeve portion of the grinding head drive-rod part is driven with grinding head by tapered connecting portion The grinding head of rod part is installed bar portion and is fixedly connected, and the grinding head is installed and be removably provided with grinding head, institute in bar portion Be provided with the outer peripheral face for stating drive sleeve portion axially extending keys for the internal perisporium of the cylinder of external thread sleeve cartridge unit on Axis extend keyway coordinate, the right part of the cylinder of the external thread sleeve cartridge unit is provided with end loops with being integrally formed It is connected in order to be removably secured with the shoulders in the drive sleeve portion by securing member, the inside of the external shell sets Be equipped with the protuberance that extends internally in the radial direction so as to by the cavity surrounded by the external shell be divided into left part inner chamber with Right part opens wide cavity, the endoporus in the protuberance by the form of axially extending key and keyway with inner screw sheath cartridge unit Cylindrical portion coordinate, the end of the cylindrical portion of the inner screw sheath cartridge unit is provided with end flange portion use with being integrally formed It is connected with being removably secured with the annulus table top portion on the right side of the protuberance by securing member, wherein, the end flange The overall diameter in portion opens wide the interior diameter of cavity less than the right part, and the diameter of bore of the end loops is installed more than the grinding head The outline diameter of bar portion, thus, the inner screw sheath cartridge unit can be dismantled with the external thread sleeve cartridge unit and by upper State right part to open wide cavity and can remove together；It is fixedly installed semi-cylindrical shield to use above the right-hand member of the external shell To form the receiving space for accommodating the grinding head, the level indicator for showing levelness on the upside of the external shell, is provided with The right-hand member of device, the left end of the external shell and the shield is fixedly installed altitude mixture control leg device, the height respectively Degree adjusts leg device includes leg housings, the height adjustment motor being fixedly installed in the leg housings inner chamber and the height Height adjusting screw rod and the female thread coordinated with the height adjusting screw rod screw thread that the rotor of degree regulation motor is fixedly connected Lower limb bar, the endoporus of the female thread lower limb bar are provided with female thread, are provided with for the inner chamber with the leg housings on outer peripheral face The key being slidably matched or the structure of keyway, the lower end of the female thread lower limb bar are provided with plate-like foot in order to being seated in construction road surface On, by being provided with limit sensors on the inside of the female thread lower limb bar in the plate-like foot, the limit sensors are described in order to work as Leg housings send signal and control the height adjustment motor and stop operating when touching the limit sensors, prevent described Leg housings move the excess of stroke.

By the present invention, the right pressure of the screw-type that produced when motor drives and rotates due to employing and while or synchronization rotation Turn such that it is able to the polishing rotation for driving grinding head to synchronize and left and right translation, and simply use a motor, therefore tie Equipment cost is reduced when closing the polishing amount for local protrusion.Meanwhile, use and screw thread can be easy to coordinate parafacies GUAN spot part is conveniently replaceable setting, can be required according to different polishing material and polishing and be changed screw thread pair at any time, So as to adjust right pressure speed；On this basis, arrange external thread sleeve end aperture more than grinding head install shank diameter so as to Can not be removed to the right and be unloaded by the interference of mounting rod（Need only to unload grinding head and seal cover board）, with When, this set can increase the diameter of screw thread matching pair, counteracting 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 smoothly removing for inner thread sleeve.Thereby, it is possible to external thread sleeve and inner thread sleeve are kept ordinatedly Entirety is removed, and is easy to dismount and is safeguarded.Increase the flexibility of equipment.And the leg that can utilize motor automatic controlled height is set Component, and use cooperatively level indicator, can according to the physical plane profile on road surface the quick adjustment whole equipment in scene level Degree so that adjust precisely so as to polishing when ensure that polishing after the completion of processing flatness.Whole equipment is reliable, knot Structure is consolidated, and can reduce the overall cost of borehole.
