Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, and in particular to a hanging column structure. Background Technology

[0002] Bailey bridges, as a prefabricated modular steel structure system, are widely used in bridge construction, temporary support platforms, and high-altitude operations due to their rapid assembly and high load-bearing capacity. During construction, it is often necessary to use hanging column structures to reliably suspend safety protection equipment (such as safety belts for workers at heights), while also meeting the requirements for convenient connection and disassembly with the Bailey bridges.

[0003] Traditional hanging column structures mainly rely on a single anti-detachment mechanism, such as:

[0004] 1. Welding-fixed type: The hanging column is directly welded to the surface of the Bailey beam. Although it can provide a rigid connection, it damages the Bailey beam base material, resulting in poor reusability. Cutting is required when dismantling, which increases construction costs and time. At the same time, the heat-affected zone of welding is prone to material performance degradation and reduces the fatigue resistance of the joint.

[0005] 2. Simple binding or bolt connection: Although it can be disassembled, it is easy to loosen, slip or even detach under long-term dynamic loads (such as wind vibration or equipment vibration), which can easily lead to high-altitude fall accidents. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a hanging column structure to solve the technical problems of poor reusability and low safety performance of traditional hanging column structures in related technologies.

[0007] This utility model provides a column hanging structure for use in Bailey beams, the column hanging structure comprising:

[0008] The column includes an upper section and a lower section connected in sequence, the upper section being used to suspend a safety belt, and the lower section being used to insert into the Bailey beam;

[0009] The first anti-detachment component includes an anti-detachment rope, one end of which is connected to the lower section and the other end of which is detachably connected to the tail end of the lower section.

[0010] The second anti-detachment component includes a bracket and an adjusting screw. The bracket is located in the lower section, and one end of the adjusting screw passes through the bracket along an axial direction perpendicular to the lower section for abutting or separating from the Bailey beam.

[0011] The first anti-detachment component and the second anti-detachment component are independently configured and both are used to prevent the lower section from separating from the Bailey beam.

[0012] Furthermore, the first anti-detachment component also includes a first hanging ring, which is fixed to the tail end of the lower section, and the anti-detachment rope is detachably disposed on the first hanging ring.

[0013] Furthermore, the anti-slip rope is detachably connected to the first hanging ring via a buckle.

[0014] Furthermore, the first anti-detachment component also includes a second hanging ring, which is fixed to the lower section and spaced apart from the first hanging ring, and the anti-detachment rope is connected to the second hanging ring.

[0015] Furthermore, the lower section has multiple positioning protrusions spaced apart on its circumferential surface. When the lower section is inserted into the Bailey beam, the positioning protrusions are exposed outside the Bailey beam.

[0016] Furthermore, the bracket has an L-shaped structure, with one end fixed to any one of the positioning protrusions, and the other end threaded through by the adjusting screw.

[0017] Furthermore, the bracket is provided with a threaded sleeve, and the adjusting screw is threadedly connected to the threaded sleeve.

[0018] Furthermore, a reinforcing rib is provided between the lower section and the support.

[0019] Furthermore, the upper section is provided with multiple collars, and the multiple collars extend in the same direction; or

[0020] At least one of the plurality of said collars extends in different directions.

[0021] Compared to existing technologies, this invention offers the following advantages: the upper section of the column is used to suspend safety belts, while the lower section is inserted into the through-hole of the Bailey beam to initially fix the column to the beam. Furthermore, the anti-detachment rope of the first anti-detachment component is connected at different positions on the lower section, forming a closed-loop constraint to prevent the column from axially detaching from the Bailey beam. Simultaneously, the adjusting screw of the second anti-detachment component laterally tightens the Bailey beam, resisting displacement caused by lateral loads and vibrations. Both components work independently, forming a double-insurance mechanism of axial locking and radial limiting. Even if a single component fails, the basic protective function is maintained, significantly reducing the risk of falls from heights. In addition, the insertion-type installation and detachable fixing method avoids damage to the Bailey beam base material. Disassembly requires no cutting, enabling rapid recycling and reuse of the column structure, reducing construction costs and time losses. Attached Figure Description

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0028] In the embodiments of this utility model, such as Figure 1 , Figure 2 As shown, the hanging column structure includes: a column body 1, a first anti-detachment component 2, and a second anti-detachment component 3; the column body 1 includes an upper section 101 and a lower section 102 connected in sequence, the upper section 101 being used to suspend a safety belt, and the lower section 102 being used to insert into the Bailey beam; the first anti-detachment component 2 includes an anti-detachment rope 201, one end of which is connected to the lower section 102, and the other end of which is detachably connected to the tail end of the lower section 102; the second anti-detachment component 3 includes a bracket 301 and an adjusting screw 302, the bracket 301 being disposed on the lower section 102, and one end of the adjusting screw 302 passing through the bracket 301 along an axial direction perpendicular to the lower section 102, for abutting or separating from the Bailey beam; wherein, the first anti-detachment component 2 and the second anti-detachment component 3 are independently arranged and both are used to restrict the separation of the lower section 102 from the Bailey beam.

[0029] Specifically, in this embodiment of the utility model, the Bailey beam is composed of multiple Bailey panels spliced ​​together in sequence. Each Bailey panel includes upper and lower chords and multiple web members connecting the upper and lower chords. Multiple through holes are provided at intervals along the length of the upper chord. These through holes can be used for temporary installation of this hanging column structure.

[0030] In this embodiment of the invention, the column 1 comprises an upper section 101 and a lower section 102 connected sequentially along its vertical direction. The upper section 101 of the column 1 is used to suspend a safety rope (or a safety rope main rope), and its lower section 102 can be inserted into the aforementioned through hole to initially fix the column 1 to the Bailey beam. In this embodiment, to improve the structural strength of the column 1 and avoid the risk of breakage at the connection between the upper section 101 and the lower section 102, the upper section 101 and the lower section 102 of the column 1 are integrally formed, and their total length meets the relevant specifications for the hanging column height. Meanwhile, the length of each section can be customized; for example... Figure 1 As shown, in this embodiment, the length of the upper segment 101 is greater than the length of its lower segment 102.

[0031] In this embodiment of the invention, a first anti-detachment component 2 is provided on the lower section 102 of the main body. The first anti-detachment component 2 has an anti-detachment rope 201. One end of the anti-detachment rope 201 is connected to the lower section 102 of the column 1, and the other end is detachably connected to the tail end of the lower section 102. Thus, when the lower section 102 is inserted into the through hole of the Bailey beam, the anti-detachment rope 201 is wrapped around the Bailey beam and connected to the tail end of the lower section 102 (i.e., the bottom of the lower section 102), thereby forming a closed-loop constraint, which can prevent the column 1 from detaching from the Bailey beam. On the other hand, the anti-detachment rope 201 and the tail end of the lower section 102 are detachably connected, and the existing through hole of the Bailey beam is used to replace the original welding connection method, so as to facilitate quick assembly and disassembly of the column 1, and also facilitate reuse, thereby improving construction efficiency.

[0032] In this embodiment of the invention, a second anti-detachment component 3 is also provided in the lower section 102 of the main body. The second anti-detachment component 3 includes a bracket 301 and an adjusting screw 302. The bracket 301 is also located in the lower section 102 and can move with the lower section 102 under the action of external force to gradually approach the Bailey beam. Then, by rotating the adjusting screw 302, the adjusting screw 302 can abut against the Bailey beam. Since the adjusting screw 302 radially penetrates the bracket 301, it can play a radial limiting role. In addition, the forward and reverse rotation of the adjusting screw 302 can change the distance between it and the Bailey beam. On the one hand, it can realize the purpose of quick installation and quick removal of the second anti-detachment component 3. On the other hand, it can also be reasonably adjusted according to the size of the Bailey beam to improve the versatility of this structure.

[0033] This embodiment, through the configuration of the first anti-detachment component 2 and the second anti-detachment component 3, forms a double-safety mechanism of axial locking and radial limiting, firmly fixing the column 1 to the Bailey beam and preventing loosening. Simultaneously, the two anti-detachment components employ a detachable connection mechanism, replacing the traditional welding method. No cutting is required after use, ensuring structural integrity and reusability while shortening the construction cycle. Furthermore, the two anti-detachment components are independently installed, meaning their installation does not affect each other. Even if one anti-detachment component fails, the other can maintain basic anti-detachment functionality for the column 1, reducing the risk of falls from heights. Of course, the anti-detachment rope 201 can be replaced individually after wear, without requiring complete removal and replacement; the adjusting screw 302 can also be directly unscrewed and replaced when damaged, ensuring construction continuity.

[0034] like Figure 2 As shown, in one embodiment, the first anti-detachment component 2 further includes a first hanging ring 202, which is fixed to the tail end of the lower segment 102, and the anti-detachment rope 201 is detachably disposed on the first hanging ring 202. Specifically, in order to connect the anti-detachment rope 201 to the tail end of the lower segment 102, this embodiment fixes the first hanging ring 202 to the tail end of the lower segment 102, and utilizes the detachable connection between the first hanging ring 202 and the anti-detachment rope 201 to achieve a detachable connection between the tail end of the lower segment 102 and the anti-detachment rope 201. Preferably, the anti-detachment rope 201 is detachably connected to the first hanging ring 202 via a buckle 203. The limiting and unlocking cooperation between the first hanging ring 202 and the buckle 203 facilitates the detachable connection between the anti-detachment rope 201 and the tail end of the lower segment 102; at the same time, the cooperation of the two makes the installation and disassembly process simple and highly reusable.

[0035] like Figure 2 As shown, in one embodiment, the first anti-detachment component 2 further includes a second hanging ring 204, which is fixed to the lower segment 102 and spaced apart from the first hanging ring 202. The anti-detachment rope 201 is connected to the second hanging ring 204. Specifically, in order to connect the end of the anti-detachment rope 201 away from the first hanging ring 202 to the lower segment 102, this embodiment provides a second hanging ring 204 at the portion of the lower segment 102 away from its tail end, and the anti-detachment rope 201 is installed at the second hanging ring 204. Of course, the anti-slip rope 201 can be made of iron chain, with one end directly attached to the second hanging ring 204 to form a whole and prevent the anti-slip rope 201 from detaching from the lower section 102; or a buckle can be set at the other end of the anti-slip rope 201, which can be detachably fixed to the second hanging ring 204. In this way, when the installation position is limited and it is not easy to fix the buckle 203 of the anti-slip rope 201 to the first hanging ring 202, another buckle can be used to detachably connect to the second hanging ring 204 to achieve a closed-loop constraint between the anti-slip rope 201 and the lower section 102.

[0036] like Figure 1 , Figure 2 As shown, in one embodiment, the lower segment 102 has a plurality of positioning protrusions 4 spaced apart on its circumferential surface. When the lower segment 102 is inserted into the Bailey beam, the positioning protrusions 4 are exposed outside the Bailey beam. Specifically, in order to limit the insertion depth of the lower segment 102 of the column 1 into the Bailey beam, this embodiment uses a plurality of positioning protrusions 4 spaced apart on the circumferential surface of the lower segment 102 to forcibly limit the insertion depth of the lower segment 102, so that when the lower segment 102 is inserted into the through hole of the Bailey beam, the positioning protrusions 4 are exposed outside the through hole. Of course, in order to facilitate extending the insertion depth of the lower segment 102, the second hanging ring 204 can be disposed above the positioning protrusions 4.

[0037] like Figure 2 As shown, in one embodiment, the bracket 301 has an L-shaped structure. One end of the bracket 301 is fixed to any one of the positioning protrusions 4, and the other end is threaded through by the adjusting screw 302. Specifically, in order to install the bracket 301 at the lower section 102 without obstructing the insertion of the lower section 102 into the through hole of the Bailey beam, this embodiment sets the bracket 301 into an L-shaped structure. On the one hand, fixing one end of the bracket 301 to any positioning protrusion 4 provides a fixed connection between the bracket 301 and the lower section 102. On the other hand, the radial thread of the adjusting screw 302 can pass through the bracket 301 at the other end of the bracket 301, allowing the adjusting screw 302 to abut against the Bailey beam, achieving a radial limiting effect. Furthermore, a notch can be formed between the L-shaped bracket 301 and the lower section 102, which can effectively avoid the Bailey beam and prevent installation interference. Of course, in order to increase the contact area between the adjusting screw 302 and the Bailey beam, a stop block can be fixed at the end face of the adjusting screw 302. The area of ​​the stop block should be larger than the cross-sectional area of ​​the adjusting screw 302.

[0038] Furthermore, such as Figure 2 As shown, in one embodiment, the bracket 301 is provided with a threaded sleeve 303, and the adjusting screw 302 is threadedly connected to the threaded sleeve 303. Specifically, in order to extend the connection length between the bracket 301 and the adjusting screw 302 and improve the stability of the adjusting screw 302, this embodiment adds a threaded sleeve 303 to the bracket 301. The threaded sleeve 303 is coaxially arranged with the adjusting screw 302, and the adjusting screw 302 can be threaded into the threaded sleeve 303. In this way, the extended threaded structure can improve the stability of the adjusting screw 302.

[0039] Furthermore, such as Figure 2 As shown, in one embodiment, a reinforcing rib 5 is provided between the lower section 102 and the support 301 to improve the structural strength of the support 301 and prevent breakage.

[0040] like Figure 1 As shown, in one embodiment, the upper section 101 is provided with a plurality of loops 6. Specifically, in order to suspend the seat belt on the upper section 101 of the column 1, a plurality of loops 6 are fixed at the upper section 101. The plurality of loops 6 can be arranged in the same direction or in different directions to improve the versatility of the structure and make the suspension direction of the seat belt unrestricted.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
