Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a base paving reference line steel wire rope suspension device. Background Art

[0002] When the paver is automatically leveling, an accurate reference plane (line) is required. The method of establishing the reference plane (line) can be selected in combination with the pavement structure layer and construction location. The reference wire rope (tightrope walking) method is used for paving the bottom layer, and the reference wire rope is installed on both sides of the pavement.

[0003] The traditional base paving reference wire rope bracket uses a high sleeve mounting bolt to fix it to the steel chisel. When adjusting the elevation, it is necessary to manually tighten the screws with a wrench. However, using bolts to adjust the elevation is not only laborious and time-consuming, but also not conducive to improving the construction efficiency of hanging wires during the base paving process.

[0004] To this end, we have made certain technical improvements to the existing base paving benchmark wire rope bracket, which will help improve the installation efficiency of the wire rope suspension device. Utility Model Content

[0005] The utility model discloses a base layer paving reference line wire rope suspension device, which aims to solve the technical problems raised in the background technology.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A base paving reference line wire rope suspension device includes a steel drill, a suspension assembly is sleeved and installed on the surface of the steel drill, the suspension assembly includes horizontal steel bars and a positioning mounting plate, the left and right sides of the positioning mounting plate are fixedly connected to horizontal positioning steel sheets, and the upper and lower ends of the positioning mounting plate are fixedly connected to vertical positioning steel sheets, the surfaces of the two horizontal positioning steel sheets are respectively provided with corresponding horizontal positioning holes, the horizontal steel bars are inserted and installed on the inner walls of the two horizontal positioning holes, and the suspension assembly is used to position the horizontal steel bars on the surface of the steel drill;

[0008] The surfaces of the two vertical positioning steel sheets are both provided with vertical positioning holes corresponding to the positions. The sizes of the vertical positioning holes match the steel chisels. The backs of the vertical positioning steel sheets are provided with positioning mechanisms.

[0009] By arranging a suspension component on the surface of the steel drill, the horizontal positioning steel plate can be used to limit the insertion of the horizontal steel bars, and the vertical positioning steel plate can be used to install and position the horizontal steel bars on the surface of the steel drill. The rigidity of the steel plate can be used to limit the horizontal steel bars. When adjusting the height of the high horizontal steel bars, it is only necessary to move the vertical positioning steel plate up and down on the surface of the steel drill to directly adjust the height of the horizontal steel bars. Compared with traditional sleeve bolt fixing, it is more convenient and time-saving.

[0010] In a preferred embodiment, the positioning mechanism includes a strip-shaped positioning box fixedly connected to the back of the positioning mounting plate, and the upper and lower surfaces of the strip-shaped positioning box are provided with corresponding mounting holes, and the inner walls of the two mounting holes are rotatably connected to a bidirectional positioning screw through bearings.

[0011] In a preferred solution, the upper and lower ends of the bidirectional positioning screw extend to the outside of the strip positioning box, and the upper and lower ends of the bidirectional positioning screw are fixedly connected to the limit block, and the surface of the bidirectional positioning screw is threadedly connected to two movable blocks.

[0012] In a preferred solution, the surface of the movable block is rotatably connected to a positioning push rod, and one end of the two positioning push rods away from the movable block is rotatably connected to the surfaces of two vertical positioning steel sheets respectively.

[0013] By providing a positioning mechanism on the back of the suspension assembly, after adjusting the height of the vertical positioning steel sheet, the two movable blocks can be driven to move by rotating the bidirectional positioning screw, thereby driving the two positioning push rods to squeeze and limit the two vertical positioning steel sheets, so that the two vertical positioning steel sheets and the steel drill are kept in a tight state, which is beneficial to the stability of the wire rope suspension assembly on the surface of the steel drill.

[0014] In a preferred embodiment, the surface of the bidirectional positioning screw is fixedly connected to a driven bevel gear, the surface of the strip-shaped positioning box is provided with an axial hole, the inner wall of the axial hole is rotatably connected to an operating rod, the front end of the operating rod is fixedly connected to a driving bevel gear, and the driving bevel gear is meshed with the driven bevel gear.

[0015] In a preferred solution, the end of the operating rod away from the driving bevel gear extends to the outside of the strip-shaped positioning box and is fixedly connected to a rotating nut.

[0016] By setting an operating lever, the operating lever can be driven to rotate by turning the rotating nut, thereby driving the driving bevel gear and the driven bevel gear to rotate, which can drive the bidirectional positioning screw to rotate inside the strip positioning box, thereby driving the two positioning push rods to limit the vertical positioning steel sheet.

[0017] In a preferred solution, the inner walls of the horizontal positioning hole and the vertical positioning hole are fixedly provided with rubber anti-slip rings, and the rubber anti-slip rings are used to prevent the horizontal steel bars and the steel drill from slipping.

[0018] By setting the rubber anti-slip ring, the surface stability of the vertically positioned steel sheet and the horizontally positioned steel sheet can be improved by using steel drills and horizontal steel bars.

[0019] As can be seen from the above, the base paving reference line wire rope suspension device provided by the present invention has the following technical effects.

[0020] First: by arranging a suspension component on the surface of the steel drill, the horizontal positioning steel plate can be used to limit the insertion of the horizontal steel bars, and the vertical positioning steel plate can be used to install and position the horizontal steel bars on the surface of the steel drill. The rigidity of the steel plate can be used to limit the horizontal steel bars. When adjusting the height of the high horizontal steel bars, it is only necessary to move the vertical positioning steel plate up and down on the surface of the steel drill to directly adjust the height of the horizontal steel bars. Compared with the traditional sleeve bolt fixing, it is more convenient and time-saving, which is conducive to improving construction efficiency.

[0021] Secondly: by providing a positioning mechanism on the back of the suspension assembly, after adjusting the height of the vertical positioning steel sheet, the two movable blocks can be driven to move by rotating the bidirectional positioning screw, thereby driving the two positioning push rods to squeeze and limit the two vertical positioning steel sheets, so that the two vertical positioning steel sheets and the steel drill are kept in a tight state, which is beneficial to the stability of the wire rope suspension assembly on the surface of the steel drill.
