Description
Technical Field
The utility model belongs to the technical field of road construction appurtenance, concretely relates to paver high accuracy guide rail.
Background
The paver working method becomes an indispensable part in the municipal engineering and highway engineering construction process, and a sensor auxiliary tool in the wire walking method, a walking guide rail is one of essential tools essential for elevation control, the traditional sensor auxiliary tool mostly adopts an aluminum alloy guide rail, the equipment has low hardness, strong ductility, weak pressure resistance and changeability, can not be used once being deformed, the paving of asphalt and stabilized sand mostly adopts a plurality of large-scale pavers and dump trucks for combined operation, the mechanization degree is high, a paver elevation control probe takes the top surface of the guide rail as a datum line to control the paving thickness, the flatness and the gradient of the asphalt and the stabilized sand, and the elevation control of a sensor is determined by the guide rail; at present, a guide rail of a sensor auxiliary tool is mostly made of aluminum alloy, a level gauge is used for measuring, jacks or skid pads are placed at two ends of the guide rail and adjusted to a required height for fixing, generally, a guide rail with five meters is used, when a sensor probe of a paver walks on the guide rail during paving, the probe senses that the plane at the top end of the guide rail is an elevation, but the middle of a new guide rail is limited by the material of the aluminum alloy guide rail, so that the collapse degree of the new guide rail is larger and larger along with time, use times and environment, the paving quality and the flatness of stable sand and asphalt are directly influenced, quality accidents occur, and huge economic losses are caused; through on-the-spot measurement, when using traditional guide rail, because sensor probe through the guide rail intermediate position department of collapsing can cause paver elevation sensing system undulant, the aggregate that traditional guide rail both sides were paved forms local wave (about 4~8 mm), and the roughness receives influence elevation control and appears the deviation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a strong, safe and reliable, the convenient operation of stability, easy nature is strong, economical and practical's paver high accuracy guide rail.
In order to achieve the above design purpose, the utility model adopts the following technical scheme: the utility model provides a paver high accuracy guide rail, is including setting up anchor pad fixed plate I and anchor pad fixed plate II at the guide rail both ends, the top of anchor pad fixed plate I and anchor pad fixed plate II all is equipped with stretch-draw lead screw, anchor pad fixed plate I and II tops of anchor pad fixed plate all are equipped with the anchor screw with stretch-draw lead screw matched with, be equipped with the atress steel band between the stretch-draw lead screw at anchor pad fixed plate I and II tops of anchor pad fixed plate, guide rail upper portion bottom surface both ends are equipped with positioning bolt I that is used for compressing tightly location atress steel band both ends, guide rail lower part top surface central point puts and is equipped with positioning bolt II that is used for compressing tightly location atress steel band middle part, guide rail both ends bottom all.
The width of the stressed steel belt is consistent with the width of the inner diameter of the guide rail.
And the tensioning screw rods at the tops of the anchor pad fixing plate I and the anchor pad fixing plate II are longitudinally and horizontally uniformly distributed.
The utility model discloses beneficial effect: after two ends of the stressed steel belt are fixedly connected with tensioning screw rods arranged at the tops of the anchor pad fixing plate I and the anchor pad fixing plate II, positioning bolts I used for pressing and positioning two ends of the stressed steel belt are arranged at two ends of the bottom surface of the upper part of the guide rail, and positioning bolts II used for pressing and positioning the middle part of the stressed steel belt are arranged at the center of the top surface of the lower part of the guide rail and are fixed in the guide rail to play a role of stretching; the top ends of the anchor pad fixing plate I and the anchor pad fixing plate II are respectively provided with an anchoring screw matched with the tension screw rod to be tightened, and the stressed steel belt fixed in the guide rail is in a tightened state; and the central position of the top surface of the lower part of the guide rail is provided with a positioning bolt II for compressing and positioning the middle part of the stressed steel belt, and when the stressed steel belt is stressed, an acting force which is upward on the guide rail is generated, so that the phenomenon that the guide rail collapses due to gravity is avoided, the width of the stressed steel belt is consistent with the width of the inner diameter of the guide rail and is connected with the tension lead screws which are longitudinally and horizontally uniformly distributed at the tops of the anchor pad fixing plate I and the anchor pad fixing plate II, and the possibility of horizontal bending of the high-precision prestressed guide rail. The utility model discloses simple structure, the cost is with low costs, circulated use and adjust the reduction error repeatedly, the effectual manpower and the material of having saved.
