Description

Technical Field

[0001] The utility model relates to the technical field of construction protection, in particular to an anti-falling safety device. Background Technique

[0002] Bridge construction often needs to be carried out at high altitudes, such as the construction of bridge piers, bridge decks and other parts. This makes the selection and setting of safety rope hanging points particularly difficult. The high-altitude operation environment is complex, and it is necessary to ensure that the hanging points are stable and reliable to prevent workers from falling accidents. Bridge construction involves multiple processes, such as foundation construction, pier and abutment construction, superstructure construction, etc. Each process has its specific safety rope hanging point requirements. As the construction progress advances, the position and number of hanging points will also change, which increases the difficulty of hanging point setting. When constructing on the bridge deck and there is no protection at both ends of the bridge deck at this time, there is no effective safety rope hanging point at this time, and the safety rope hanging point needs to follow the principle of hanging high and using low. At present, the traditional method is to fix a long rod on site and use the long rod as the safety rope hanging point. Such a method has the following defects: the construction range of construction workers is limited, and they can only construct around the long rod area. If they need to leave this range, they need to remove the safety rope and bind it to another long rod, which poses a safety hazard during the process. Therefore, we propose an anti-falling safety device. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Embodiment 1, as Figures 1 - 3As shown in the figure, the present utility model provides a technical solution: an anti-falling safety device, which includes a column structure 2 and L-shaped plates 4 arranged on both sides of the top of the column structure 2. The L-shaped plates 4 include a horizontal plate 401 and a vertical plate 402. A plurality of slideway column bars 5 are vertically arranged on the surfaces of the horizontal plate 401 and the vertical plate 402. A hanging ring structure 3 for binding with a safety rope is inlaid and slidably arranged outside the slideway column bars 5. The column structure 2 includes a top plate 201, a column 202, and a base 203 fixedly connected in sequence from top to bottom. The base 203 is anchored and connected to the bridge surface 1 through an anchor rod 204.

[0020] In a specific embodiment of the present utility model, the L-shaped plate 4 is pre-installed with the column structure 2, and then, according to the length of the bridge surface 1, the anti-falling device is modularly spliced (as shown in Figure 1 the figure). The splicing standard is that two adjacent L-shaped plates 4 are horizontally aligned without gaps, and the slideway column bars 5 of two adjacent anti-falling devices can be seamlessly aligned, facilitating the hanging ring slider 301 to slide on the slideway columns of the two anti-falling devices. Thus, the wearer of the high-altitude safety belt cooperating with the hanging ring structure 3 can walk safely on the bridge surface 1, and it can always be ensured that the high-altitude safety belt is slidably matched with the slideway column bars 5 through the hanging ring structure 3. The T-shaped structure of the slideway column bars 5 is matched with the T-shaped groove of the slider 301, which can not only prevent the slider 301 from separating from the slideway column bars 5 but also enable the slider 301 to slide only along the slideway column bars 5. The base 203 of the column structure 2 is tightly assembled with the bridge surface 1 through the anchor rod 204. When disassembling later, first remove the anchor rod 204, and then separate the L-shaped plate 4 from the column structure 2, so as to facilitate storage and recycling and is conducive to subsequent recycling.

[0021] In a preferred technical solution, the horizontal plate 401 is tightly connected to the top plate 201 through bolts, and the vertical plate 402 is tightly connected to the side surface of the column 202 through bolts. Subsequently, only the corresponding bolts need to be disassembled to separate the L-shaped plate 4 from the column structure 2, so as to carry out storage and recycling, which is convenient for subsequent reuse.

[0022] In a preferred technical solution, the slideway column bar 5 includes a T-shaped slide rail 502 and a bottom plate 501. The bottom plate 501 is detachably connected to the L-shaped plate 4 through bolts. The slideway column bar 5 is installed on the L-shaped plate 4 by means of bolt fastening, which is convenient for subsequent removal and replacement of damaged components.

[0023] In a preferred technical solution, the hanging ring structure 3 includes a slider 301 and a hanging ring 302. The slider 301 is provided with a T-shaped groove that is inlaid and slidably connected to the T-shaped slide rail 502. When the T-shaped slide rail 502 is inlaid and slidably matched with the slider 301, it can not only prevent the slider 301 from separating from the slideway column bars 5 but also enable the slider 301 to slide only along the slideway column bars 5. Thus, the wearer of the high-altitude safety belt cooperating with the hanging ring structure 3 can walk safely on the bridge surface 1.

[0024] In the preferred technical solution, a plurality of reinforcing rib blocks 6 are welded between the horizontal plate 401 and the vertical plate 402 , and the distance between two adjacent reinforcing rib blocks 6 is set to 50 cm. The reinforcing rib blocks 6 can enhance the bending strength of the L-shaped plate 4 .

[0025] To sum up, the present embodiment provides an assembled anti-fall device, which is modularly spliced ​​according to the length of the bridge deck 1. The hanging ring structure 3 cooperates with the high-altitude safety belt, and the column structure 2 is anchored on the bridge deck 1. The hanging ring structure can slide on the L-shaped plate 4 on both sides of the column structure 2, and the hanging ring slider 301 can slide on the slide columns of the two anti-fall devices, so that the wearer of the high-altitude safety belt matched with the hanging ring structure 3 can walk safely on the bridge deck 1. Each slide column 5 is only provided with one hanging ring structure 3, so that the various hanging ring structures 3 do not affect each other, thereby ensuring that personnel are not affected when walking on the bridge deck 1, thereby improving the safety of personnel.
