Description

Technical Field

[0001] The present invention relates to the technical field of pavement construction, and particularly to an auxiliary device for guiding the wire of a concrete guardrail in pavement paving construction. Background Art

[0002] As the pavement structural layer is the part of the road that directly bears the vehicle load, the quality of the pavement structural layer directly determines the service life of the road and the driving comfort. At present, the automatic leveling device for guiding the wire of a paver is generally used to control the thickness and top surface flatness of the pavement structural layer. When encountering a concrete guardrail or a bridge guardrail during construction, one method is to drive steel pins at a certain distance from the edge of the pavement near the guardrail and hang a wire. This process is likely to cause damage to the concrete structural layer of the bridge deck and quality diseases in the later stage caused by secondary construction of the reserved edge. Another method is to set steel pins and hang a wire above the concrete guardrail, which requires modifying the sensor of the paver from the lower part to the upper part. The modification process is cumbersome, and the too high position of the sensor will also affect the paving accuracy of the paver, resulting in the pavement flatness being difficult to achieve the ideal effect.

[0040] In a preferred embodiment, the steel wire slot 33 is a V-shaped slot. The V-shaped slot structure helps the steel wire to automatically center and position itself in the slot. The angle design of the V shape enables the steel wire to slide naturally along the V-shaped surface to the bottom center position after being placed, achieving good positioning without precise manual adjustment. This not only improves the efficiency of construction preparation but also effectively prevents the steel wire from shifting left and right in the slot, making the elevation positioning of the steel wire more accurate. In addition, compared with slots of other shapes, the V-shaped slot has a better clamping force and restraint on the steel wire when bearing external vibration and impact. During the road surface construction process, the paver will generate certain vibrations. The V-shaped slot can keep the steel wire better in the fixed position in the slot, preventing it from jumping out of the slot or changing position due to vibration, thereby ensuring that the entire leveling device provides a stable and reliable elevation reference for the paver, further improving the flatness and precision of the road surface paving construction, and fundamentally guaranteeing the construction quality of the road surface structure layer.

[0043] The usage method of the road surface paving method construction concrete guardrail wire routing auxiliary device is as follows:

[0044] Install the device on the concrete guardrail

[0045] Place the top plate 11 of the clamping seat 1 on the top surface of the railing of the concrete guardrail 6. Since the top end of the fixed clip 12 (the first angle steel) has been fixedly connected to one end of the top plate 11 and the opening faces the movable clip 13, the top end of the movable clip 13 (including the second angle steel and the hinge) is hingedly connected to the end of the top plate 11 away from the fixed clip 12 through the hinge. At this time, the right-angle edge of the second angle steel is fixedly connected to the outer side of the sleeve 14.

[0046] Drive the sleeve 14 to move by rotating the adjusting screw 17. The sleeve 14 drives the movable clip 13 to rotate around the hinge, so that the movable clip 13 (the second angle steel) and the fixed clip 12 (the first angle steel) clamp the concrete guardrail 6 together.

[0047] Adjust the height of the vertical rod

[0048] According to the construction requirements, slide the vertical rod 2 up and down in the sleeve 14. After adjusting to the appropriate height position, thread the first locking bolt 18 into the second threaded hole in the middle of the sleeve 14 perpendicular to its axial direction, so that one end of the first locking bolt 18 passes through the second threaded hole and presses against the vertical rod 2 to stabilize the position of the vertical rod 2 in the sleeve 14 and prevent displacement due to vibration and other factors during construction.

[0049] Adjust the position of the horizontal rod and the wire card slot

[0050] According to different road widths or construction requirements, slide the movable rod 32 along the axis of the fixed rod 31 to adjust the extended length of the movable rod 32, and then adjust the position of the wire card slot 33 so that the wire card slots 33 of multiple devices are on a straight line.

[0051] After the position is determined, thread the second locking bolt 34 into the third threaded hole provided in the fixed rod 31, so that one end of the second locking bolt 34 passes through the third threaded hole and presses against the movable rod 32 to prevent the movable rod 32 from sliding due to external forces and other factors during construction and ensure the stable position of the wire card slot 33.

[0052] Place and fix the steel wire

[0053] Place the steel wire 7 in the wire card slot 33 (V-shaped groove) at the top of the end of the horizontal rod 3 away from the vertical rod 2. The V-shaped groove structure will automatically center and position the steel wire at the center position of the bottom of the groove.

[0054] Put the rope sleeve 43 at the top of the hanging rope 41 on the outside of the movable rod 32, and make the top end of the hanging rope 41 press the steel wire 7 located in the wire card slot 33. The bottom end of the hanging rope 41 is fixedly connected to the counterweight 42. Relying on the gravity of the counterweight 42, the steel wire 7 is continuously and stably pressed in the wire card slot 33 to prevent the steel wire from loosening or shifting during construction.

[0055] Construction

[0056] When the paver is used for pavement paving construction, the device provides a stable and accurate leveling reference for the paver. The paver uses the elevation information of the steel wire 7 to control the thickness and top surface flatness of the pavement structural layer, so as to ensure the construction quality of the pavement structural layer when constructing near the concrete guardrail 6.

[0057] Demolition device

[0058] After the construction is completed, rotate the adjusting screw 17 in the reverse direction to loosen the clamping of the concrete guardrail 6 by the movable clamping member 13 and the fixed clamping member 12, and remove the device from the concrete guardrail. If it is necessary to store the device or use it at other positions later, each component can be inspected and maintained.

The sleeve drives the movable clamping member to rotate around the hinge, so that the movable clamping member and the fixed clamping member clamp the concrete guardrail together; According to the construction requirements, slide the vertical rod up and down in the sleeve, adjust to the appropriate height position and maintain this height position, and prevent displacement during construction due to factors such as vibration; Place the steel wire on the steel wire clamping groove at the top of the end of the horizontal rod away from the vertical rod; Press the pressing member against the steel wire located in the steel wire clamping groove, and rely on the gravity of the pressing member to continuously and stably press the steel wire in the steel wire clamping groove to prevent the steel wire from loosening or shifting during construction; When the paver is constructing by the surface layer paving method, this device provides a stable and accurate leveling reference for the paver. The paver uses the elevation information of the steel wire to control the thickness and top surface flatness of the pavement structural layer, so as to ensure the construction quality of the pavement structural layer when constructing near the concrete guardrail.
