Description

Technical Field

[0001] The invention discloses a high-efficiency and environment-friendly safety suspension component based on high-altitude operation, belonging to the technical field of building construction safety protection. Background Art

[0002] During the renovation stage of the project, there are many operations near the edge openings. There are no effective protective measures after the external frame is removed. The temporary protective height is 1.2m. There is a greater risk of falling from a height when working on the inside of the opening. In view of this situation, it is necessary to arrange safety belt hanging points at the operation site to ensure the personal safety of construction workers. One of the methods is the penetration method, that is, using expansion bolts or screws that penetrate the wall as safety belt hanging points, such as the technical solution disclosed in the Chinese utility model patent with application number 202120517261.6, application date March 11, 2021, and patent name "A high-altitude exterior wall safety belt fixing and anchoring device". However, when this method is implemented, the expansion bolts need to be implanted in the concrete structure to take effect, and the expansion bolts will damage the finished wall, increasing the maintenance cost of the finished wall.

[0003] With the continuous improvement of technology, some solutions have also appeared in the prior art that use the support force to arrange hanging points on the exterior wall, such as the technical solution disclosed in the Chinese utility model patent with application number 201920307982.7, application date March 12, 2019, and patent name "A balcony construction safety belt hanging device"; the technical solution disclosed in the Chinese invention patent with application number 202211736017.4, application date December 31, 2022, and patent name "Convenient and movable safety belt bolting and construction method"; and the technical solution disclosed in the Chinese invention patent with application number 202223041435.X, application date November 16, 2022, and patent name "A safety belt clamp".

[0004] The above technical solution is similar in approach, where a frame with an opening is provided, a plate-like structure is fixed on one side of the opening end of the frame, a through hole is provided on the other side of the opening end, and a bolt is passed through the through hole. Another plate-like structure is fixed at the end of the bolt, and the plate-like structures on both sides of the opening end are arranged opposite to each other. Then a nut is arranged on one side of the through hole, and the bolt passes through the nut and is threadedly connected with the nut while passing through the nut. By turning the bolt, the distance between the plate-like structures on both sides is continuously shortened, and the wall is clamped on both sides of the wall.

[0005] The advantage of this method is its simple structure, but it generally has the following defects: when the barrel bolt is turned, the plate-like structure at the end of the bolt will rotate while gradually approaching the plate-like structure on the other side. In the process of fitting with the exterior wall and gradually clamping, the rotating plate-like structure will continuously grind the exterior wall surface and cause damage to the wall surface. In order to make it rotate by turning the end of the bolt, when the length of the screw is long, the operator needs to eject the upper body a long distance to complete it, which increases the difficulty of operation and also poses certain safety hazards. Utility Model Content

[0006] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and to provide an efficient and environmentally friendly safety suspension component based on high-altitude operations, in which only axial movement occurs during the locking process of a clamping bolt, the safety of construction workers is ensured when working on the inner side of the opening during the decoration stage, and damage to the exterior wall is avoided.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the high-efficiency and environmentally friendly safety suspension component based on high-altitude operations includes a suspension frame and a lifting ring fixed on the side of the suspension frame, an opening is provided on one side of the suspension frame, an anti-skid steel plate is fixed on one side of the open end of the suspension frame, a through hole is provided at the opening on the other side of the suspension frame, a clamping bolt is installed in the through hole, and a clamping plate opposite to the anti-skid steel plate is fixed at one end of the clamping bolt. It is characterized in that: a receiving groove is provided at the open end of the suspension frame, a driving nut assembly is rotatably clamped in the receiving groove, the clamping bolt simultaneously passes through the driving nut assembly and is threadedly connected to the driving nut assembly, and a limiting member for preventing the clamping bolt from rotating is also provided on the inner wall of the through hole.

[0008] Preferably, a limiting groove is axially provided on the surface of the clamping bolt, and the limiting member is a limiting protrusion provided on the inner wall of the through hole, and the limiting protrusion is stuck in the limiting groove.

[0009] Preferably, the drive nut assembly includes a coaxially fixed sleeve and a clamping nut, the sleeve is clamped in the accommodating groove, and the clamping nut extends to the outer side of the suspension frame; the inner hole of the sleeve is coaxially arranged with the threaded hole of the clamping nut, and the clamping bolt is threadedly connected with the clamping nut.

[0010] Preferably, the suspension frame includes vertically arranged secondary ribs and main ribs, the secondary ribs and the main ribs are fixed as a whole through a vertically arranged bottom beam, the anti-slip steel plate is fixed to the upper end of the secondary ribs, and the accommodating groove is opened at the upper end surface of the main ribs.

[0011] Preferably, a reinforcing rod is further provided between the secondary ribs and the main ribs, and two ends of the reinforcing rod are respectively fixed to the middle of the secondary ribs and the main ribs.

[0012] Preferably, the accommodating groove includes two sections with different widths, wherein the inner section is wider than the outer section, and the outer section is opened outward to the end face of the main rib; the sleeve includes a two-section structure with different radii, the thin section of the sleeve is coaxially fixed with the clamping nut, the thick section is clamped in the inner section of the accommodating groove, and the clamping nut extends to the outer side surface of the main rib.

[0014] Preferably, the hanging ring is fixed on the side of the secondary rib.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In this high-efficiency, environmentally friendly, safe suspension assembly based on height operations, the clamping bolt only has axial movement during the clamping process. Therefore, while ensuring the holding force, it avoids the damage to the exterior wall caused by the clamping bolt in the prior art when clamping the exterior wall due to both axial movement and rotation during the clamping process.

[0017] The clamping of the external wall is achieved only by rotating the clamping screw, which avoids the difficulty of operating the clamping bolt from the end to make it move in the prior art, thereby improving safety.

[0018] The main ribs are solid structures, and the secondary ribs, bottom beams and reinforcing rods are hollow tube structures, which ensures the firmness of the suspension assembly while reducing the weight and processing cost of the suspension assembly.

[0019] After the clamping bolt passes through the main rib and the driving nut assembly, the clamping bolt is supported by the through hole at the main rib so that the clamping bolt is in a horizontal or approximately horizontal state. At the same time, the threaded connection between the clamping bolt and the clamping nut in the driving nut assembly is utilized, and the driving nut assembly is limited by the clamping bolt and the receiving groove at the same time. Therefore, in actual use, there is no need to block the upper port of the receiving groove, thereby reducing the processing difficulty of the suspension assembly.

[0020] The limiting protrusion only serves to prevent the clamping bolt from rotating, so the strength requirement for the limiting protrusion itself is relatively low. Therefore, in actual operation, the limiting protrusion can be directly realized by the welding point formed by the welding machine, which not only ensures its function, but also further reduces the difficulty of on-site processing.

DETAILED DESCRIPTION

[0028] Figures 1 to 6 It is the best embodiment of the utility model, and the following Figures 1 to 6 The utility model is further described.

[0029] like Figures 1 to 3 As shown, a high-efficiency, environmentally friendly, safe suspension component for high-altitude operations (hereinafter referred to as the suspension component) includes a suspension frame, and the suspension frame includes two vertically arranged ribs: a secondary rib 1 and a main rib 5. A bottom beam 9 is horizontally arranged at the bottom of the secondary rib 1 and the main rib 5. The secondary rib 1 and the main rib 5 are respectively vertically fixed at the two ends of the upper surface of the bottom beam 9. A reinforcing rod 8 is also arranged between the secondary rib 1 and the main rib 5. The reinforcing rod 8 is horizontally arranged, and its two ends are respectively fixed at the middle of the secondary rib 1 and the main rib 5. The upper end of the suspension frame is open, and the reinforcing rod 8 is the end of the opening of the suspension frame.

[0030] A lifting ring 10 is provided on the back side of the secondary rib 1 , an anti-skid steel plate 2 is fixed on the upper end of the secondary rib 1 facing the main rib 5 , and a clamping mechanism opposite to the anti-skid steel plate 2 is provided on the upper end of the main rib 5 .

[0031] Combination Figures 4 and 5The main rib 5 is a solid structure, and the secondary rib 1, the bottom beam 9 and the reinforcing rod 8 preferably adopt a hollow tube structure, which ensures the sturdiness of the suspension assembly while reducing the weight and processing cost of the suspension assembly. A clamping bolt 4 is provided that passes through the top of the main rib 5, and the axis of the clamping bolt 4 is directly opposite to the center of the anti-slip steel plate 2. A clamping nut 6 is provided at the end face of the main rib 5 facing away from the secondary rib 1. The clamping bolt 4 passes through the clamping nut 6 while passing through the main rib 5 and is threadedly connected with the clamping nut 6. A clamping plate 3 is fixed at the end face of the clamping bolt 4 facing the anti-slip steel plate 2, and an end nut 7 is fixed at the end face of the clamping bolt 4 facing away from the anti-slip steel plate 2, and the end nut 7 plays a role in limiting the clamping bolt 4.

[0032] Combination Figures 4 and 5 A through hole is provided at the top of the main rib 5, the diameter of the through hole is larger than the outer diameter of the clamping bolt 4, and the clamping bolt 4 passes through the through hole and penetrates the main rib 5. A receiving groove 12 is also provided downward on the upper end surface of the main rib 5, and the receiving groove 12 is provided downward at the through hole and communicated with the through hole.

[0033] The receiving groove 12 includes two sections with different widths, wherein the inner section is wider than the outer section, and the outer section is opened outward to the end surface of the main rib 5. Since the cross section of the receiving groove 12 is a structure of inner width and outer narrowness, the inner side of the receiving groove 12 forms a slot structure.

[0034] A sleeve 13 is provided which is coaxially fixed with the clamping nut 6. The sleeve 13 includes a two-stage structure with different radii, and the end with a smaller radius in the sleeve 13 is coaxially fixed with the clamping nut 6. The inner hole of the sleeve 13 is coaxially arranged with the threaded hole of the clamping nut 6, and the aperture of the inner hole of the sleeve 13 is larger than the aperture of the threaded hole of the clamping nut 6.

[0035] The driving nut assembly consisting of a clamping nut 6 and a sleeve 13 coaxially fixed is placed in the receiving groove 12 from the upper end surface of the main rib 5. The width of a narrower section in the receiving groove 12 is greater than the diameter of the thin section of the sleeve 13 but smaller than the diameter of the thick section of the sleeve 13, and the width of a wider section in the receiving groove 12 is greater than the diameter of the thick section of the sleeve 13. Therefore, after the driving nut assembly is placed in the receiving groove 12, the thick section of the sleeve 13 enters the wider section of the receiving groove 12, and the clamping nut 6 is located on the outside of the main rib 5, so that the driving nut assembly can be rotatably clamped on the upper end surface of the main rib 5.

[0036] At the same time, after the driving nut assembly falls into the bottom of the receiving groove 12, the inner hole of the sleeve 13, the threaded hole of the clamping nut 6 and the through hole on the upper end surface of the main rib 5 are aligned in sequence. The clamping bolt 4 passes through one side of the main rib 5 and is threadedly connected with the clamping nut 6, and then passes through the main rib 5 and the driving nut assembly at the same time.

[0037] It should be specially noted here that after the clamping bolt 4 passes through the main rib 5 and the driving nut assembly at the same time, the clamping bolt 4 is supported by the through hole at the main rib 5 so that the clamping bolt 4 is in a horizontal or approximately horizontal state. At the same time, the threaded connection between the clamping bolt 4 and the clamping nut 6 in the driving nut assembly is utilized, and the driving nut assembly is limited by the clamping bolt 4 and the receiving groove 12 at the same time. Therefore, in actual use, there is no need to block the upper port of the receiving groove 12, thereby reducing the processing difficulty of the suspension assembly.

[0038] A limiting groove 11 is axially provided on the upper surface of the clamping bolt 4, and the limiting groove 11 preferably passes through both ends of the clamping bolt 4. A limiting protrusion 14 is provided on the upper part of the inner wall of the through hole in the main rib 5, and the limiting protrusion 14 is stuck in the limiting groove 11. The limiting protrusion 14 only serves to prevent the clamping bolt 4 from rotating, so the strength requirement of the limiting protrusion 14 itself is relatively low. Therefore, in actual operation, the limiting protrusion 14 can be directly realized by the welding point formed by the welding machine, which ensures its function and further reduces the difficulty of on-site processing.

[0039] The specific working process and principle are as follows:

[0040] like Figure 6 As shown, the bayonet of the suspension assembly is clamped on the protruding portion of the outer wall 17, and the end of the outer wall 17 is placed against the surface of the reinforcing rod 8, and then the clamping nut 6 is rotated using a tool. Since the clamping nut 6 is threadedly connected to the clamping bolt 4, and when the clamping bolt 4 passes through the main rib 5, the clamping bolt 4 will not rotate on its own due to the action of the limiting protrusion 14 in the through hole in the main rib 5, but will only move axially.

[0041] As the clamping bolt 4 continuously moves axially toward the outer wall 17 , after the clamping plate 3 contacts the outer wall 17 , the clamping plate 3 and the anti-slip steel plate 2 located on both sides of the outer wall 17 clamp the outer wall 17 together. After a certain holding force is reached, the clamping nut 6 stops rotating. At this time, the strength of the accommodating groove 12 provides holding force to the sleeve 13 and the clamping nut 6, so that the clamping bolt 4 can reliably clamp the outer wall 17 .

[0042] Then one end of the safety rope 16 (or safety belt) equipped with the hanging ring 15 is connected to the lifting ring 10, and the other end of the safety rope 16 (or safety belt) is connected to the worker to provide safety guarantee.

[0043] As can be seen from the above, in the present suspension assembly, the clamping bolt 4 has only axial movement during the clamping process, so under the premise of ensuring the holding force, the damage to the outer wall 17 caused by the clamping bolt 4 during the clamping process and the axial movement and rotation of the clamping bolt 4 is avoided when the outer wall 17 is clamped. At the same time, the clamping of the outer wall 17 is achieved only by rotating the clamping nut 6, which also avoids the difficulty of the prior art in which the clamping bolt 4 needs to be rotated from the end to make it move, thereby improving safety.

[0044] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
