Description

Technical Field

[0001] This utility model relates to the field of building construction safety technology, and in particular to a portable safety belt attachment device for high-altitude operations in building construction. Background Technology

[0002] During the construction of masonry work at building edges and the plastering of ceilings, workers need to wear safety belts to ensure their safety. Currently, safety belt attachment points are often attached to embedded rings in the reinforcing bars used to reinforce wall and column formwork, or to expansion bolts with hooks installed on the main structure for securing the safety belts. Attaching safety belts to embedded rings does not meet the principle of "high attachment, low use" for both masonry work at building edges and plastering of ceilings. Furthermore, embedded rings increase steel bar waste, requiring manual removal later, increasing material and labor costs. Additionally, since embedded rings are primarily used to reinforce wall and column formwork, their fixed positions cannot cover all areas of edge work and ceiling plastering. Installing expansion bolts with hooks can easily damage the main structure, and the subsequent removal of these bolts requires significant labor, potentially causing further damage and affecting later decoration and finishing work. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a portable safety belt attachment device for high-altitude construction work.

[0004] To achieve the above objectives, the present invention can adopt the following technical solution:

[0005] The portable safety belt attachment device for high-altitude construction work of this utility model includes a fixing ring for insertion into a reserved hole for water and electricity, consisting of two parallel straight segments and two symmetrically arranged arc segments. The fixing ring has a first separator and a second separator on its inner side, which divide the fixing ring into a left U-shaped segment, a middle parallel segment, and a right U-shaped segment. A rotating ring is slidably fitted on the left U-shaped segment, and the rotating ring has a limiting stop bar. A limiting pin is connected to the right U-shaped segment by a connecting rope. The second separator has a limiting hole that matches the limiting pin.

[0006] Furthermore, the first partition is a partition cross brace fixed to the inner side of the fixed ring, and the second partition is a partition plate fixed to the inner side of the fixed ring, with the limiting insertion hole opened on the partition plate.

[0007] Furthermore, the limiting stop rod passes through the groove on the inner side of the left U-shaped segment, and the middle part of the limiting stop rod is fixed to the outer ring surface of the rotating ring. The length from the fixing point to both ends of the limiting stop rod is greater than the length of the groove on the inner side of the left U-shaped segment, so that the limiting stop rod can be blocked by the dividing cross brace to prevent the limiting stop rod from rotating 360° around the rotating ring.

[0008] Furthermore, a connecting ring is provided at one end of the limiting pin, one end of the connecting rope is looped around the right U-shaped segment, and the other end is looped around the connecting ring.

[0009] Furthermore, a limiting ring with an outer diameter larger than the diameter of the limiting insertion hole is fixedly sleeved in the middle of the limiting pin, thereby forming a stop through the limiting ring to limit the position of the limiting pin inserted into the limiting insertion hole.

[0010] The advantages of this utility model are that it can be easily installed in the water and electricity reserved holes on the building wall, and the limit stop bar and limit pin are used to form a clamping and fixing on the inner and outer sides of the building wall, thereby easily completing the installation and arrangement of the safety belt hanging point. It can be installed and adjusted at any time according to the work site of the operator. Moreover, the processing cost of the whole device is low, the material input is small, and the disassembly and assembly efficiency is high. Attached Figure Description

[0012] Figure 2 yes Figure 1 A bottom view.

[0013] Figure 3 yes Figure 1 Installation diagram. Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1-3As shown, the portable safety belt attachment device for high-altitude construction work of this utility model includes a fixing ring 1 for insertion into the water and electricity reserved hole 100. The fixing ring 1 is composed of a pair of parallel straight segments and a pair of symmetrically arranged arc segments. The arc segment on the left connects the left ends of the two straight segments into one, and the arc segment on the right connects the right ends of the two straight segments into one, thus forming a flat circular structure fixing ring 1. The inner side of the fixing ring 1 is provided with a first separator 2 and a second separator 3. The first separator 2 and the second separator 3 are both horizontally spanned between the two straight sections of the fixing ring 1, dividing the entire fixing ring 1 into a left U-shaped section 1.1, a middle parallel section 1.2, and a right U-shaped section 1.3. A rotating ring 4 that can slide back and forth is fitted on the left U-shaped section 1.1. A limiting stop bar 5 that can be locked outside one side of the water and electricity reserved hole 100 is fixed to the rotating ring 4. A limiting pin 7 is connected to the right U-shaped section 1.3 by a connecting rope 6. A limiting insertion hole 8 that matches the limiting pin 7 is opened on the second separator 3. The length of the limiting pin 7 should be greater than the diameter of the water and electricity reserved hole 100. So when the limiting pin 7 is inserted into the limiting insertion hole 8, it can be locked outside the other side of the water and electricity reserved hole 100 opposite to the limiting stop bar 5, so that the entire fixing ring 1 can be stably inserted into the water and electricity reserved hole 100.

[0016] Specifically, the first partition 2 is a partition cross brace fixed to the inner side of the fixing ring 1, while the second partition 3 is a partition plate fixed to the inner side of the fixing ring 1, and the limiting insertion hole 8 is opened on the partition plate.

[0017] The limiting stop 5 passes through the groove inside the left U-shaped section 1.1. The middle part of the limiting stop 5 is fixed to the outer ring surface of the rotating ring 4. The length from the fixed point to both ends of the limiting stop 5 is greater than the length of the groove inside the left U-shaped section 1.1. Thus, the limiting stop 5 can be blocked by the first separator 2, preventing the limiting stop 5 from rotating 360° under the drive of the rotating ring 4.

[0018] One end of the limiting pin 7 is provided with a connecting ring 9. At this time, one end of the connecting rope 6 is looped around the right U-shaped segment 1.3, and the other end is looped around the connecting ring 9. In addition, in order to limit the position of the limiting pin 7 inserted into the limiting hole 8, a limiting ring 10 with an outer diameter larger than the diameter of the limiting hole 8 can be fixed in the middle of the limiting pin 7, so that the limiting ring 10 can form a limiting stop.

[0019] In actual processing, common materials found on the construction site can be used:

[0020] The first step is to take a 10mm diameter round steel bar, bend it twice at 180°, and weld the two ends together to ensure that the two ends have an overlap of at least 8cm. This forms the fixing ring 1. Note that when welding the fixing ring 1, an M12 nut should be fitted on it first as a rotating ring 4.

[0021] The second step involves using a 6mm diameter Class III threaded steel bar as a dividing cross brace, which is placed between the two straight segments of the fixed ring 1. The dividing cross brace is then welded to the two straight segments of the fixed ring 1 to form the first dividing element 2. The first dividing element 2 can hold the rotating ring 4 on the left U-shaped segment 1.1 of the fixed ring 1, preventing the rotating ring 4 from sliding towards the middle parallel segment 1.2.

[0022] The third step involves using a galvanized flat iron piece with a length of 3cm and a width of 2.5cm as a partition plate, which is placed horizontally between the two straight segments of the fixing ring 2. The partition plate is then welded to the two straight segments of the fixing ring 1 to form the second partition 3. At this point, a through hole with a diameter of 10mm is made in the center of the second partition 3 (i.e., the partition plate) as a limiting insertion hole 8.

[0023] The fourth step involves using a 20mm diameter round steel bar as a limiting stop bar 5, which passes through the groove inside the left U-shaped section 1.1. The middle part of the limiting stop bar 5 is welded and fixed to the outer ring surface of the rotating ring 4. The length from the welding point to both ends of the limiting stop bar 5 is greater than the length of the groove inside the left U-shaped section 1.1, so that the limiting stop bar 5 can be blocked by the first separator 2 (i.e., the separator cross brace), preventing the limiting stop bar 5 from rotating 360° under the drive of the rotating ring 4.

[0024] The fifth step involves using a 10mm diameter round steel bar as a limiting pin 7, welding an M12 nut to one end as a connecting ring 9, binding a 3mm diameter steel wire rope to the connecting ring 9 as a connecting rope 6, and binding the other end of the steel wire rope to the right U-shaped section 1.3 of the fixing ring 1. Then, an M12 nut is fitted into the middle of the limiting pin 7 and welded to form the limiting ring 10, thus completing the processing and manufacturing of the entire portable safety belt attachment device.

[0025] In use, first slide the rotating ring 4 to the farthest end away from the first separator 2, then rotate the limiting stop 5 so that one side of it is locked on the first separator 2, forming a closed state. Then, before the limiting pin 7 is inserted into the limiting hole 8, insert the fixing ring 1 together with the limiting stop 5 into the water and electricity reserved hole 100. After the limiting stop 5 has completely passed through the water and electricity reserved hole 100, the limiting stop 5 can be rotated in the opposite direction again so that it is locked outside the opening on one side of the water and electricity reserved hole 100.

[0026] When the limiting stop 5 is engaged and locked outside one side of the water and electricity reserved hole 100, the limiting insertion hole 8 on the second separator 3 just protrudes from the other side of the water and electricity reserved hole 100. At this time, the limiting pin 7 is inserted into the limiting insertion hole 8, so that it is just locked outside the other side of the water and electricity reserved hole 100 opposite to the limiting stop 5, so that the entire fixing ring 1 can be stably installed in the water and electricity reserved hole, and the right U-shaped section 1.3 protruding outside the water and electricity reserved hole 100 just forms the safety belt attachment point, thus completing the installation of the entire portable safety belt attachment point device for high-altitude building construction (e.g. Figure 3 (As shown). By using the limiting stop bar 5 and the limiting pin 8 to form a locking and fixing mechanism on the inner and outer sides of the building wall, the installation and arrangement of the safety belt attachment points can be easily completed. It can be installed and adjusted at any time according to the work site of the operator. Moreover, the processing cost of the whole device is low, the material input is small, and the disassembly and assembly efficiency is high.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
