[0028] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0029] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0030] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0031] like Figures 1 to 6 As shown, a curved guardrail auxiliary device includes a column 10, a guardrail tube 20 and a lifter 30.

[0032] The column 10 includes a rib plate 11 and a side plate 12 ; the side plate 12 surrounds the rib plate 11 and is fixedly connected; the rib plate 11 is provided with an auxiliary hole 111 ; and the side plate 12 is provided with a mounting through hole 121 .

[0033] The guardrail tube 20 includes a bent tube 21 and a bracket 22 . The bent tube 21 and the bracket 22 are provided with bracket through holes, and the bracket through holes and the mounting through holes 121 of the column 10 form a mounting hole group.

[0034] When the guardrail tube 20 is installed on the first column 10, its bracket through hole and the installation through hole 121 are easily aligned; however, due to the manufacturing error and installation error of the curvature of the guardrail tube 20, the second bracket through hole of the guardrail tube 20 cannot be aligned with the installation through hole 121 of the next column 10.

[0035] The lifting and pressing device 30 includes an insertion shaft 31, a rotating seat 32, a lifting and pressing head 33, and a lever 34; wherein the insertion shaft 31 is used to be inserted into the auxiliary hole 111 of the column 10; the rotating seat 32 and the insertion shaft 31 are rotatably arranged, and the lever 34 slides through the rotating seat 32, and a lifting and pressing head 33 is fixedly arranged at one end of the lever 34, and the lifting and pressing head 33 is a channel steel, and the channel steel is used to be clamped on the outside of the curved tube 21. In this way, when the height of the guardrail tube 20 needs to be adjusted, the worker holds the end of the lever 34 away from the lifting and pressing head 33, and corrects the curvature of the guardrail tube 20 by lifting and pressing. Due to the existence of the lever 34, the guardrail tube can be easily lifted and pressed to deform.

[0036] For further information, see Figure 4 The holding handle 40 is fixed to the end of the lever 34 away from the lifting head 33.

[0037] Furthermore, a gripping hole is provided in the middle of the gripping handle 40 ; and a rubber layer is fixedly provided on the outer side wall of the gripping handle 40 .

[0038] Furthermore, a plug section 311 is provided at the other end of the plug shaft 31 away from the rotating seat 32 ; the outer diameter of the plug section 311 is thinner than the main body of the plug shaft 31 ; the auxiliary hole 111 can only be passed by the plug section 311 , and the main body of the plug shaft 31 cannot be inserted into the rib plate 11 .

[0039] For further information, see Figure 5 The plug section 311 defines a mounting groove 3111 .

[0040] A portion of the rotating plate 50 is located in the mounting groove 3111 , and the rotating plate 50 is rotatably connected to the plug section 311 .

[0041] After the rotating plate 50 and the plug section 311 are inserted into the auxiliary hole 111 , the rotating plate 50 is rotated to a vertical state in space. The rotating plate 50 is used to lie horizontally at the outer end of the auxiliary hole 111 to prevent the insertion shaft 31 from being separated from the rib plate 11 .

[0042] The above description is only a preferred embodiment of the present utility model patent and is not intended to limit the present utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model patent shall be included in the protection scope of the present utility model patent.
