DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] like Figure 1-6 As shown, the embodiment of the present application discloses a construction engineering guardrail, including a riser 10, a crossbar 20, and a vertical bar 30. There are two risers 10, two crossbars 20, and both are arranged between the two risers 10. The two crossbars 20 are arranged vertically at intervals. There are several vertical bars 30 arranged between the two crossbars 20, and several vertical bars 30 are arranged horizontally at intervals. The riser 10, crossbar 20, and vertical bars 30 form a guardrail. A ground nail rod 11 is slidably provided at the lower part of the riser 10. The lower end of the ground nail rod 11 is conical and convenient for insertion into the soil layer. A rack 12 is provided at the top of the ground nail rod 11, and a hammer rod 13 is provided at the top of the rack 12. The rack 12 and the hammer rod 13 are both slidably connected to the inner wall of the riser 10. The total length of the riser 10, the rack 12, and the hammer rod 13 is greater than the length of the riser 10. An opening 14 is formed in the riser 10 at the location corresponding to the rack 12. A slide 40 is mounted horizontally and slidably on the outer wall of the riser 10 adjacent to the opening 14. Two slides 40 are located in front of the opening 14 and are provided with a rotating shaft 41 at one end thereof, which rotates together. The length of the rotating shaft 41 is perpendicular to the length of the slides 40. A gear 42 is rotatably mounted on the rotating shaft 41 and meshes with the rack 12. One end of the rotating shaft 41 passes through the slides 40 and is provided with a crank 43. A fixing assembly 50 is provided on the riser 10 to secure the slides 40.

[0031] When installing the guardrail on muddy ground, first put the riser 10 in a vertical state, then slide the slide plate 40 and fix it through the fixing assembly 50, so that the gear 42 is separated from the rack 12, and then hammer the top of the hammer rod 13, so that the hammer rod 13, the rack 12, and the ground nail rod 11 descend, and the ground nail rod 11 is nailed into the soil to ensure the stability of the guardrail, and the gear 42 is separated from the rack 12 to avoid the gear 42 or the rack 12 being damaged by the large impact at the contact point between the gear 42 and the rack 12 during hammering; when the guardrail needs to be removed, first slide the slide plate 40 so that the gear 42 is meshed with the rack 12, and then fix the slide plate 40 through the fixing assembly 50 to fix the position of the gear 42, and finally turn the crank 43 to drive the rack 12 and the gear 42 to move, so that the ground nail rod 11 is pulled out of the soil, which is more convenient and labor-saving, and reduces the labor intensity of the staff.

[0032] Specifically, support plates 16 are horizontally disposed at the bottom of both sides of the vertical tube 10. The length of the support plates 16 is perpendicular to the length of the crossbar 20, ensuring stability during initial placement of the vertical tube 10. The support plates 16 also provide support for the vertical tube 10 during ground spike removal, preventing it from sinking into the soil. This also allows the guardrail to be placed on a concrete floor without using the ground spike rods 11, expanding its use in a wide range of scenarios. A horizontal chute 15 is disposed on the outer wall of the vertical tube 10 adjacent to the opening 14. The slide 40 is slidably connected to the chute 15, ensuring the stability of the slides 40. A connecting block 80 is commonly disposed on the side of the two slides 40 facing away from the rotation axis 41. A traction handle 81 is disposed on the side of the connecting block 80 facing away from the vertical tube 10. Pulling the traction handle 81 moves the connecting block 80, thereby driving the two slides 40 to move synchronously. The connecting block 80 also connects the two slides 40, increasing structural strength.

[0033] During installation, the fixing assembly 50 includes a fixing block 51 disposed on the outer side of the slide 40, away from the rotation axis 41. The fixing block 51 has a first fixing hole 52 and a second fixing hole 53 spaced apart along the length of the slide 40, with the first fixing hole 52 being closer to the rotation axis 41 than the second fixing hole 53. A mounting block 60 is disposed on the outer wall of the riser 10, away from the opening 14, above the slide 40. The mounting block 60 has a vertical sliding hole 61, within which a sliding rod 62 slides. A connecting plate 63 is horizontally disposed at the bottom of the sliding rod 62, and a lifting handle 64 is disposed at the top. The length of the connecting plate 63 is perpendicular to the length of the slide 40. Fixing posts 65 are disposed on both sides of the bottom of the connecting plate 63, so that when the lifting handle 64 is pulled, the sliding rod 62, connecting plate 63, and fixing posts 65 move synchronously. The fixing posts 65, the first fixing hole 52, and the second fixing hole 53 all have the same diameter. Slide the slide 40 so that the first fixing hole 52 is concentric with the fixing rod. Then, by pulling the handle 64, control the slide 62, connecting plate 63, and fixing column 65 to descend, so that the two fixing columns 65 are respectively placed in the corresponding first fixing holes 52, fixing the fixing block 51 and the slide 40. At this time, the gear 42 is engaged with the rack 12. Slide the slide 40 so that the second fixing hole 53 is concentric with the fixing rod. Then, by pulling the handle 64, control the slide 62, connecting plate 63, and fixing column 65 to descend, so that the two fixing columns 65 are respectively placed in the corresponding second fixing holes 53, fixing the fixing block 51 and the slide 40. At this time, the gear 42 is separated from the rack 12. The lower edge of the fixing column 65 is chamfered to facilitate the insertion of the fixing column 65 into the first fixing hole 52 or the second fixing hole 53.

[0034] In the specific setting, a clamping block 70 is provided on the outer wall of the vertical pipe 10 away from the opening 14 and below the slide plate 40. Two clamping holes 71 are provided on the clamping block 70 at intervals. The clamping holes 71 are consistent with the diameter of the fixing column 65 and are concentric. After the fixing column 65 passes through the first fixing hole 52 or the second fixing hole 53, its lower end is placed in the clamping hole 71, so that the lower end of the fixing column 65 also has a force-bearing point, which makes the fixing effect of the fixing block 51 and the slide plate 40 better.

[0035] The principle of use of a construction engineering guardrail in this embodiment is as follows: when installing the guardrail on muddy ground, first put the riser 10 in a vertical state, the support plate 16 contacts the ground, then slide the slide plate 40 so that the second fixing hole 53 is concentric with the fixing column 65, then pull the lifting handle 64 to control the sliding rod 62, the connecting plate 63, and the fixing column 65 to descend, so that the two fixing columns 65 are respectively placed in the corresponding second fixing holes 53, then hammer the hammer rod 13, so that the hammer rod 13, the rack 12, and the ground nail rod 11 descend, and the ground nail rod 11 is nailed into the soil to ensure the stability of the guardrail; when the guardrail needs to be removed, Pull the lifting handle 64 to control the sliding rod 62, the connecting plate 63, and the fixing column 65 to rise, so that the fixing rod leaves the second fixing hole 53, and then slide the slide plate 40 to make the gear 42 engage with the rack 12, and then pull the lifting handle 64 to control the sliding rod 62, the connecting plate 63, and the fixing column 65 to descend, so that the two fixing columns 65 are respectively placed in the corresponding first fixing holes 52, thereby fixing the position of the gear 42, and finally turning the crank 43 to drive the rack 12 and the gear 42 to move, so that the ground nail rod 11 is pulled out of the soil, which is more convenient and labor-saving, and reduces the labor intensity of the staff.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
