Description

Technical Field

[0001] This utility model belongs to the field of paving height marking technology, and in particular relates to a paving height marking device for water-stabilized layers. Background Technology

[0002] A water-stabilized layer is short for a cement-stabilized crushed stone layer, which is made by compacting and curing cement-bonded graded crushed stone. Water-stabilized layers have high strength, stiffness, and stability. For asphalt pavements, the water-stabilized layer is the main load-bearing layer of the entire road structure and is an important structure to ensure the stability of the entire road structure, effectively transferring the vertical load of the road to the subgrade.

[0003] When laying water-stabilized layers, it is necessary to lay water-stabilized layers of appropriate height according to the terrain conditions. In the existing technology, the steel ropes pre-installed by the roadside are mainly used as the reference standard for the paver. The steel ropes are generally fixed and supported by pre-installed columns. When setting up the columns, it is necessary to pay attention to controlling their verticality and corresponding height to ensure that the height of the steel ropes hanging on the columns meets the standard. Therefore, when setting up the columns, it is necessary to pay attention to the fact that many variables lead to a low column setting speed and low efficiency of height marking device deployment. Utility Model Content

[0004] This utility model provides a height marking device for water-stabilized layer paving, which aims to solve the problem that the current column setting process requires attention to many variables, resulting in a low column setting rate and low efficiency in the deployment of height marking devices.

[0005] This utility model is implemented as follows: a water-stabilized layer paving height marking device, comprising:

[0006] A fixed rod, the top of which is provided with an adjustment mechanism, and a calibration unit is arranged inside the adjustment mechanism;

[0007] The adjustment mechanism includes an upper fixed plate, a lower fixed plate, and a screw rod disposed between the upper fixed plate and the lower fixed plate, and the screw rod is provided with a push bolt;

[0008] The calibration unit includes a sliding plate that slides on the screw and a support rod provided on the ring side of the sliding plate. The sliding plate is provided with a sliding hole, and the sliding plate is nested in the screw through the sliding hole. The sliding plate is lifted up during the screwing process of the push bolt.

[0009] Preferably, the support rod is provided with a wire groove for fixing the steel rope.

[0010] Preferably, at least three sets of guide rods are provided between the upper fixed plate and the lower fixed plate, and the sliding plate is provided with guide holes adapted to the guide rods. The sliding plate moves along the screw axis under the limiting action of the guide holes and guide rods.

[0011] Preferably, the support rod includes a connecting rod and an external rod rotatably connected to the connecting rod, the wire groove is provided on the external rod, and the connecting rod is connected to the outer wall of the sliding plate.

[0012] Preferably, the diameter of the sliding hole is larger than the diameter of the screw.

[0013] Preferably, the outer rod is further provided with a locking bolt, which extends from the end of the outer rod away from the connecting rod and enters the wire groove, and the end of the locking bolt abuts against the steel rope located in the wire groove.

[0014] Preferably, the end face of the external rod is provided with a nested cavity for accommodating the insertion of the connecting rod, the portion of the connecting rod inserted into the nested cavity is provided with an annular groove, and the inner wall of the nested cavity is provided with an annular protrusion, which engages within the annular groove.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] This utility model embodiment provides a water-stabilized layer paving height marking device, such as... Figures 1-5 As shown, the water-stabilized layer paving height marking device includes:

[0028] A fixed rod 200 is provided, and an adjustment mechanism 100 is provided at the top of the fixed rod 200. A calibration unit 300 is arranged inside the adjustment mechanism 100. The fixed rod 200 is set in a suitable position and fixed before the elevation is determined. The fixed rod 200 can be pre-embedded by opening a fixing hole groove in the roadbed. When adjusting the height, the adjustment mechanism 100 is used to adjust the height of the calibration unit 300 so that the calibration unit 300 supports the steel rope used to indicate the paving height of the water-stabilized layer. It is necessary to pay attention to adjusting the orientation of the calibration unit 300 when the fixed rod 200 is buried to ensure that the orientation of the calibration unit 300 is perpendicular to the forward direction of the paver.

[0029] The adjustment mechanism 100 includes an upper fixed plate 110, a lower fixed plate 120, and a guide rod 132 and a screw 131 disposed between the upper fixed plate 110 and the lower fixed plate 120;

[0030] The calibration unit 300 includes a sliding plate 310 and a support rod 320. The sliding plate 310 slides on the guide rod 132 and the screw 131. The sliding plate 310 is mainly assembled with the screw 131 and the guide rod 132 through its own sliding hole 301 and guide hole 302. The guide rod 132 is adapted to the guide hole 302, mainly to ensure the straightness of the sliding plate 310's movement direction. The screw 131 is provided with a pushing bolt 140, which rotates and moves on the screw 131 to change its position.

[0031] The support rod 320 is located on the circumferential side of the sliding plate 310. The support rod 320 is provided with a wire groove 3201 for fixing the steel rope. Here, the support rod 320 includes a connecting rod 321 and an external rod 322 rotatably connected to the connecting rod 321. The wire groove 3201 is located on the external rod 322. The connecting rod 321 is connected to the outer wall of the sliding plate 310. The steel rope is placed in the wire groove 3201. The external rod 322 is provided with a locking hole 3202. One end of the locking hole 3202 is an open structure that communicates with the outside, and the other end communicates with the wire groove 3201. A locking bolt 323 is provided in the locking hole 3202. The locking bolt 323 extends through the locking hole 3202 into the wire groove 3201 and clamps and fixes the steel rope.

[0032] In this application, the steel wire groove 3201 fixing method mainly reduces the impact on the height control accuracy caused by the pressure applied during the movement of the paver and the swaying of the steel rope. When the steel rope can also be directly supported by the support rod 320, the impact of the steel rope swaying interference needs to be considered.

[0033] In this embodiment, the fixing rod 200 only needs to determine the vertical state and the orientation of the calibration unit 300 during the fixing process. The subsequent height control is mainly achieved by fine-tuning through the adjustment mechanism 100. When controlling the height between sections, the difficulty of the column setting process is reduced by reducing the need for height control during the early stage of column setting. The adjustment process after setting up the column is completed by adjusting the height through the adjustment mechanism 100, which reduces the workload of setting up the column and thus improves the efficiency of the water-stabilized layer paving height marking device.

[0034] In a preferred embodiment of this invention, at least three sets of guide rods 132 are provided between the upper fixed plate 110 and the lower fixed plate 120. The sliding plate 310 is provided with guide holes 302 that are adapted to the guide rods 132. The sliding plate 310 moves axially along the screw 131 under the limiting action of the guide holes 302 and the guide rods 132. The number of guide holes 302 is not less than three sets to ensure that the sliding plate 310 can move in a planar manner. It should be noted that when arranging the guide holes 302, the distance between two sets of guide holes 302 should be kept sufficient to facilitate the operation of the push bolt 140 located at the center of the sliding plate 310.

[0035] In this embodiment, the diameter of the sliding hole 301 is larger than the diameter of the screw 131, and the size of the pushing bolt 140 is larger than the diameter of the sliding hole 301. During the screwing process, the pushing bolt 140 will lift the sliding plate 310.

[0036] In a preferred embodiment of this invention, the end face of the external rod 322 is provided with a nested cavity 3203 for accommodating the insertion of the connecting rod 321. The portion of the connecting rod 321 inserted into the nested cavity 3203 is provided with an annular groove. The inner wall of the nested cavity 3203 is provided with an annular protrusion, which is engaged in the annular groove.

[0037] In this embodiment, the purpose of the rotatable connection between the external rod 322 and the connecting rod 321 is to reduce the angle change of the steel rope when the terrain changes and the steel rope between the adjacent water-stabilized layer paving height marking devices is not parallel to the horizontal line, so that the transition is smoother.
