Description

Technical Field

[0001] The utility model relates to a warning sign fixing device for mud ground. Background Art

[0002] In construction sites and other workplaces, warning signs are needed to warn outsiders or uninformed persons. Existing warning signs are generally placed directly on the ground. In order to prevent them from falling down due to strong winds or impacts, heavy objects are often added to the base of the warning signs. However, this method requires the ground to be relatively flat, and when subjected to strong winds or strong impacts, the warning signs will also fall down due to large shaking arcs. Another method is to fix the base directly to the ground with stakes, but the stakes will be pulled out of the ground when hit by a strong force in places with soft soil, which will also cause the warning signs to fall down. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a warning sign fixing device for mud ground.

[0004] The utility model is realized through the following technical solutions.

[0005] The utility model provides a warning sign fixing device for mud ground, comprising a fixing pile, a base, and a fixing nut; the upper ends of a plurality of fixing piles are all installed on the base and are respectively locked by a fixing nut, the lower end and the middle part of the fixing pile are inserted into the ground, a column is fixed on the base, and a warning sign is fixed on the top of the column, the fixing pile comprises a pile nail, a drill bit is processed at the lower end of the pile nail, a rotating drum is installed in the middle of the pile nail, the maximum diameter of the drill bit is the same as the outer diameter of the rotating drum, a plurality of arc cutter discs are installed on the pile nails in the rotating drum, an outer hexagonal rotating sleeve and a clamping ring are provided on the top of the rotating drum, and the top of the clamping ring is fixedly connected to the lower end face of the base.

[0006] The arc cutter disc includes a plurality of arc cutters, which are mounted on a fixed disc. A plurality of fixed discs are evenly fixed in the middle of the pile nail. Both sides of one end of the arc cutter are processed into blade surfaces, and the inner side of the other end is hinged to the fixed disc. A strip hole along the radial direction of the fixed disc is processed on the outer side. A push rod is arranged in the strip hole. The push rod is fixed to the rotating drum through a connecting seat. Holes are reserved on the rotating drum corresponding to the arc cutters.

DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0018] A warning sign fixing device for mud ground includes a fixing pile 1, a base 2, and a fixing nut 3; the upper ends of several fixing piles 1 are all installed on the base 2 and are locked by a fixing nut 3 respectively, the lower end and middle part of the fixing pile 1 are inserted into the ground, a column 4 is fixed on the base 2, and a warning sign 5 is fixed on the top of the column 4, the fixing pile 1 includes a pile nail 6, a drill bit 15 is processed at the lower end of the pile nail 6, and a rotating drum 10 is installed in the middle of the pile nail 6. The maximum diameter of the drill bit 15 is the same as the outer diameter of the rotating drum 10, so that the outer top of the brick 15 is connected to the bottom of the rotating drum 10 smoothly, reducing friction. There are several arc cutter discs installed on the pile nail 6 in the rotating drum 10, and the top of the rotating drum 10 is provided with an outer hexagonal rotating sleeve 9 and a clamping ring 7, and the top of the clamping ring 7 is fixedly connected to the lower end face of the base 2.

[0019] like Figure 1 As shown, two ends of the base of the warning sign are respectively nailed into the ground using a fixing pile 1.

[0020] The arc cutter disc includes a plurality of arc cutters 14, which are mounted on a fixed disc 19. The plurality of fixed discs 19 are evenly fixed at the middle of the pile nail 6. Both sides of one end of the arc cutter 14 are processed into blade surfaces, and the inner side of the other end is hinged to the fixed disc 19. The outer side is processed with a strip hole 18 along the radial direction of the fixed disc 19. A push rod 13 is arranged in the strip hole 18. The push rod 13 is fixed to the rotating drum 10 through a connecting seat 12. Holes are reserved on the rotating drum 10 corresponding to the arc cutters 14. Figure 2 The plane at the top of the drill bit 15 is used as a fixed disk.

[0021] When in use, first retract the arc knife, then nail two fixed piles 1 into the ground at a certain distance, exposing the outer hexagonal rotating sleeve 9, and then adjust the heights of the two fixed piles 1 to be almost the same, use a wrench to rotate the outer hexagonal rotating sleeve 9, and driven by the rotating drum 10, the arc knife cross-cuts into the soil, such as Figure 4 As shown; then install the advertising plate on the pile nail and lock it with the locking screw. When you need to retract the warning sign, remove the locking nut, take down the warning sign, then turn over the hexagonal rotating sleeve to retract the arc knife into the rotating drum, and then pull out the fixed pile.

[0022] In order to prevent the holes on the rotating drum from causing the surface of the rotating drum to be uneven when the fixing piles are nailed into the ground, the outer arc size of the arc knife 14 is made the same as the outer arc size of the rotating drum 10, and when the push rod 13 is at the innermost side of the strip hole 18, the outer edge of the arc knife 14 is aligned with the outer edge of the rotating drum 10, so that the arc knife can fill the reserved holes on the rotating drum 10 and make the surface of the rotating drum 10 as smooth as possible.

[0023] In addition, when the arc knife is retracted, it can cut the land better. The arc knife 14 is processed so that the connection between the two sides of the blade surface is a sharp angle.

[0024] In order to reduce the external force required for the rotation of the drum, a bearing 8 is installed between the outer hexagonal rotating sleeve 9 and the peg 6. The upper edge of the outer hexagonal rotating sleeve 9 is evenly processed with square grooves, and the lower edge of the retaining ring 7 is processed with a square protrusion corresponding to the position of the direction groove. Due to the length limit of the strip hole on the arc knife, the maximum rotation angle of the outer hexagonal rotating sleeve 9 is fixed. Therefore, when the retaining ring 7 is welded on the base, it only needs to be calibrated to correspond to the position of the square groove on the outer hexagonal rotating sleeve 9 after the arc knife is unfolded.

[0025] In order to prevent the head of the pile from being deformed after multiple impacts, which would make it impossible to install the locking nut, a pile head 16 with a diameter smaller than the entire pile 6 is processed on the top of the pile 6, so that the pile head 6 will not affect the installation of the locking nut after a small amount of deformation occurs during the impact.
