[0037] It should be noted that the positioning spike 110 provides basic support by being nailed into a roadbed, the meshing section 111 is matched with the matching hole 211 of the adjusting connecting piece 210 to realize height adjustment, in the adjusting process, the smooth section 112 is arranged to enable the adjusting connecting piece 210 to be more smoothly adjusted relative to the positioning spike 110, and accurate control of the height is facilitated; the adjusting connecting piece 210 is fixedly connected with the supporting piece 310 to form a stable overall structure, the through hole 311 on the supporting piece 310 is adjustably connected with the hanger 320, and the groove 321 of the hanger 320 is used for connecting and fixing the steel wire rope.

[0038] It can be understood that, referring to Figure 1 , the adjusting connecting piece 210 is fixedly connected with the supporting piece 310, so that the adjusting connecting piece 210 and the supporting piece 310 can be synchronously adjusted on the positioning spike 110, specifically, referring to Figure 6 , the adjusting connecting piece 210 and the supporting piece 310 are fixedly connected in a vertical direction through a fastener 400, wherein the fastener 400 can be a bolt, a screw, a rivet or other connecting pieces with good fixing effect. Then, the meshing structure of the adjusting connecting piece 210 and the positioning spike 110 can realize height adjustment in a vertical direction, prevent relative rotation, and ensure adjustment accuracy and stability; the through hole 311 on the supporting piece 310 is adjustably connected with the hanger 320, so that the steel wire rope can be positionally adjusted in a horizontal direction, and the steel wire rope can be ensured to maintain a proper connection angle with the paver, thereby improving construction flexibility.

[0039] Wherein, referring to Figure 1 , the lower end of the positioning spike 110 is provided with a pointed cone part 113. The pointed cone part 113 facilitates the positioning spike 110 to be nailed into a roadbed, and reduces the nailing resistance.

[0040] Further, referring to Figure 4 , 5The engagement section 111 of the positioning drill 110 is a half gear structure, and the matching hole 211 of the adjusting connecting piece 210 is a half gear hole matched with the half gear structure. The gear part of the half gear structure is arranged towards the extension direction of the steel wire rope, and the gear part of the half gear hole of the adjusting connecting piece 210 is arranged towards the same direction as the gear part of the half gear structure. The two gear parts are in staggered contact through gear engagement, effectively preventing horizontal rotation caused by excessive tension of the steel wire rope, and improving the stability of the overall structure. In some embodiments, in addition to the half gear structure, square spline, polygonal spline, and plum blossom spline engagement structures can also be used. These structures can also achieve the function of preventing horizontal rotation and ensure the stability of the adjusting device.

[0041] The adjusting connecting piece 210 is a steel sheet, and the half gear through hole 311 can be made by machining the steel sheet on a machine tool. The end of the adjusting connecting piece 210 is also provided with a first handle. The first handle can be easily held and adjusted by the operator, and the movement of the adjusting connecting piece 210 can be more stably controlled during the adjustment of the height, improving the accuracy of the adjustment and the convenience of the operation.

[0042] In some embodiments, referring to Figures 2-6 The adjusting assembly 200 further includes fixing columns 212 arranged at both ends of the adjusting connecting piece 210, and stays 213 for providing outward tension, the two ends of the stay 213 being connected to the fixing columns 212 at both ends respectively. It can be understood that the stay 213 provides an outward tension force for the adjusting connecting piece 210, avoiding the degradation of the elastic ability of the adjusting connecting piece 210, which causes upward and downward displacement during paving, and reducing the actual paving height caused by the upward and downward displacement of the steel wire rope support, which does not conform to the planned paving height. The number of stays 213 can be two, three or more to provide sufficient tension. The material of the stay 213 can be high-strength steel wire, elastic alloy or other materials with good elasticity and durability.

[0043] Further, referring to Figure 6 The fixing column 212 is a hook structure, and the hook extends outwardly from the end of the adjusting connecting piece 210.

It can be understood that the stay 213 placing groove 214 prevents the stay 213 from interfering with other components and the stay 213 from being displaced, thereby ensuring the stability and safety of the device. Specifically, the adjusting connecting piece 210 is a C-shaped structure, and two hooks are uniformly distributed at the two ends thereof. At this time, the number of stays 213 is two, and the corresponding placing grooves 214 are also two. The stays 213 are hung on the opposite hooks through the placing grooves 214, thereby providing sufficient outward tension for the adjusting connecting piece 210.

[0046] In some embodiments, with reference to Figures 1 to 6 The support 310 is a C-shaped structure, and the through hole 311 is arranged at the two ends of the support 310.

[0047] Further, with reference to Figures 1 to 3 , 5, one end of the hanger 320 away from the groove 321 is provided with a threaded structure 322. One end of the threaded structure 322 penetrates through the through hole 311 of the support 310, and the threaded structure 322 cooperates with a nut 323 to fix the hanger 320 on the support 310. It can be understood that the cooperation of the threaded structure 322 and the nut 323 not only firmly fixes the hanger 320 on the support 310, but also adjusts the position of the hanger 320 by adjusting the tightening degree of the nut 323, thereby achieving horizontal adjustment. The steel wire rope coincides with the vertical boundary line of the paving, and the nut 323 finally abuts against the support 310, thereby avoiding that the hanger 320 is pulled out due to the tension of the steel wire rope, and improving the paving efficiency. Specifically, the hanger 320 is a cylindrical rod structure, and the through holes 311 at the two ends of the support are circular holes.

[0048] In use, first, the pointed cone part 113 of the positioning drill 110 is downward, and the half-toothed gear meshing section 111 is nailed into the roadbed in the direction of the extension of the steel wire rope. Then, the adjusting connecting piece 210 is held by hand, the half-toothed gear hole cooperates with the meshing section 111 of the positioning drill 110, the height of the hanger 320 is adjusted by sliding the adjusting connecting piece 210 up and down, and the toothed gear of the two is locked after being loosened. The steel wire rope is placed and fixed in the groove 321 of the hanger 320, and the steel wire rope is kept in appropriate tension by adjusting the nut 323, thereby realizing the positioning of the hanger 320 in the vertical and horizontal directions.

[0049] The device effectively limits the displacement of the hanger 320 in the vertical and horizontal directions through the cooperation of the half gear meshing structure and the threaded connection, and significantly improves the flatness and elevation accuracy of paving.
