Technical Field
[0001] This utility model belongs to the field of safety protection technology, and specifically refers to an installation structure for a fall arrest rope. Background Technology
[0002] Fall arrest ropes are key protective components used in high-altitude operations, equipment maintenance, and construction to prevent people or objects from falling. They provide safety by being securely connected to a fixed object, thus avoiding personal injury or property damage caused by accidental falls.
[0003] However, existing fall arrest rope installation structures suffer from structural complexity and cumbersome installation. For example, some winding installation structures require repeated winding around the object before threading on a locking buckle for fixation, resulting in tedious operation and insufficient locking reliability. Other clamping structures lack convenient pre-fixation designs, requiring continuous manual support and positioning during tightening of the locking components, increasing the difficulty and risk of working at heights. Furthermore, the clamping range of such structures is often fixed, making it difficult to adapt to beams, slabs, and other objects of varying thicknesses on site. Therefore, there is an urgent need for a fall arrest rope installation structure that is easy to install, reliably locks, and has a wide range of applications. Utility Model Content
[0004] This invention solves the problems mentioned in the background art by using the opening of the clamping body to hold the object in place, using an adjustable drive arm to drive the pressure plate to pre-press, and then using locking bolts to push the pressure plate and the lower frame together to clamp.
[0005] The purpose of this utility model is achieved as follows: an installation structure for a fall arrest rope, comprising: The clamping body includes a connecting frame, an upper frame, and a lower frame. The upper frame and the lower frame are respectively located at the upper and lower ends of the connecting frame and together enclose an opening for inserting and fixing an object. The locking mechanism includes a locking bolt threaded to the upper frame, an adjustable drive arm hinged to the upper frame, and a pressure plate connected to the lower part of the adjustable drive arm and extending into the opening. The lower end of the locking bolt can push against the pressure plate so that the pressure plate and the lower frame can work together to clamp the fixed object located between them.
[0006] The present invention is further provided with an anti-slip structure on the bottom surface of the pressure plate and the top surface of the lower frame.
[0007] The present invention is further provided that the locking bolt is also provided with a locking nut.
[0008] The present invention is further configured such that the bottom of the locking bolt is provided with a positioning head, and the pressure plate is provided with a positioning groove that matches the positioning head.
[0009] The present invention is further configured such that the positioning head is a conical structure with the tip pointing downwards.
[0010] The present invention is further configured such that the adjustable drive arm is a telescopic arm structure, which includes a telescopic inner arm and a telescopic outer arm that are sleeved together.
[0011] The present invention is further provided with at least one hanging ring on the outer side of the connecting frame for connecting a fall arresting rope.
[0012] By adopting the above technical solution, the beneficial effects that this utility model can achieve are: 1. The clamping body quickly engages and fixes the object through its opening, and the adjustable drive arm drives the pressure plate to achieve pre-tightening, reducing installation steps and improving installation convenience.
[0013] 2. By using locking bolts to push the pressure plate and the lower frame together to clamp, a stable clamping is formed, which enhances the locking reliability of the fixed object.
[0014] 3. The adjustable drive arm and locking bolt structure can adapt to the installation requirements of fixed objects of different specifications, thus improving the applicability of the structure. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figs. 1-3 : Example 1: This embodiment provides an installation structure for a fall arrest rope, including: The clamping body 3 includes a connecting frame 30, an upper frame 31 and a lower frame 32. The upper frame 31 and the lower frame 32 are respectively located at the upper and lower ends of the connecting frame 30, and together they enclose an opening 4 for inserting and fixing the object 10. The locking mechanism 5 includes a locking bolt 50 threadedly connected to the upper frame 31, an adjustable drive arm 51 hinged to the upper frame 31, and a pressure plate 52 connected to the lower part of the adjustable drive arm 51 and extending into the opening 4. The lower end of the locking bolt 50 can push against the pressure plate 52 so that the pressure plate 52 and the lower frame 32 cooperate to clamp the fixed object 10 located between them.
[0018] The installation structure of the fall arrest rope 1 is a device used to securely connect the fall arrest rope 1 to the fixed object 10, providing a reliable installation base for the fall arrest rope 1 and ensuring that the fall arrest rope 1 can effectively play its role in preventing falls. It is composed of a clamping body 3 and a locking mechanism 5. Through a secure connection with the fixed object 10, it transmits the tension borne by the fall arrest rope 1 to the fixed object 10, ensuring the safety of the relevant work scenario.
[0019] The fixed object 10 refers to the various load-bearing components clamped by the installation structure of the fall arrest rope 1. These components come in various forms, including H-beams commonly used in construction and equipment installation, as well as steel components such as I-beams, channel steel, and rectangular steel pipes. These fixed objects 10 must have sufficient structural strength to withstand the tension transmitted by the fall arrest rope 1, provide a stable installation foundation for the installation structure of the fall arrest rope 1, adapt to the clamping form of the opening 4 and the clamping action of the locking mechanism 5, and meet the installation and fixing requirements of the fall arrest rope 1 in different scenarios.
[0020] The clamping body 3 is used to provide a contact frame with the fixed object 10 and form a clamping space; its structure includes a connecting frame 30, an upper frame 31 and a lower frame 32. The upper frame 31 and the lower frame 32 are respectively fixed to the upper and lower ends of the connecting frame 30, and together they enclose the opening 4, which is a frame shape adapted to the fixed object 10. The connecting frame 30 is fixed to the upper frame 31 and the lower frame 32 by welding. It serves as the mounting carrier of the locking mechanism 5 and cooperates with the locking mechanism 5 to clamp and fix the fixed object 10.
[0021] The connecting frame 30 is an intermediate connecting component of the clamping body 3, used to connect the upper frame 31 and the lower frame 32 to form a complete clamping structure; its structure is long strip or plate-shaped, and its shape is adapted to the ends of the upper frame 31 and the lower frame 32. It is located between the upper frame 31 and the lower frame 32, connecting the two into one; ensuring the structural stability of the clamping body 3, and keeping the upper frame 31 and the lower frame 32 in a relatively fixed positional relationship.
[0022] The upper frame 31 is the upper structure of the clamping body 3, which cooperates with the lower frame 32 and the connecting frame 30 to form a clamping space. Its structure is a plate-shaped structure fixed to the upper end of the connecting frame 30, and it is provided with threaded holes for the locking bolt 50 to pass through. Its shape corresponds to the lower frame 32, providing a mounting point for the locking bolt 50 and the adjustable drive arm 51.
[0023] The lower frame 32 is the lower structure of the clamping body 3, serving as the lower support for clamping and fixing, and working with the pressure plate 52 to clamp and fix the object 10; the top surface is the contact surface that supports the fixed object 10, and its shape corresponds to that of the upper frame 31. It is used to support the bottom of the fixed object 10 and works with the pressure plate 52 to apply clamping force to the fixed object 10.
[0024] The opening 4 is a space on the clamping body 3 for accommodating the fixed object 10, providing a channel for the fixed object 10 to enter the clamping area, making it easy to quickly place the fixed object 10; it is formed by the upper frame 31, the lower frame 32 and the connecting frame 30, which makes it easy for the fixed object 10 to be quickly inserted into the clamping space from the opening, providing a basis for subsequent clamping operations.
[0025] The locking mechanism 5 is used to mechanically engage the pressure plate 52 with the lower frame 32 to firmly clamp the fixed object 10. It includes a locking bolt 50, an adjustable drive arm 51 and a pressure plate 52. The three work together to complete the clamping action. By transmitting and amplifying the force, the pressure plate 52 and the lower frame 32 generate a stable clamping force on the fixed object 10, ensuring that the installation structure and the fixed object 10 do not move relative to each other.
[0026] The locking bolt 50 generates a downward thrust through the tightening action, pushing the pressure plate 52 to clamp and fix the object 10. Its structure is a rod-shaped structure with external threads. The thread of the rod body matches the threaded hole of the upper frame 31. Its shape is a standard bolt with an operating head at one end. It passes through the threaded hole of the upper frame 31, and the lower end contacts the top surface of the pressure plate 52 through tightening. The rotational motion is converted into axial thrust by the thread transmission, providing a continuous clamping force for the pressure plate 52.
[0027] The adjustable drive arm 51 is used to drive the pressure plate 52 to rotate or move to achieve pre-tightening, and can also be adjusted to adapt to the fixed objects 10 of different specifications. Its structure is a rod-shaped structure with adjustable length or angle. The upper part is connected to the upper frame 31, and the lower part is fixed to the pressure plate 52. The upper part is movably connected to the upper frame 31 by hinge, and the lower part is fixed to the pressure plate 52 by welding. It is used to transmit driving force to drive the pressure plate 52 to move, and can ensure that the pressure plate 52 can contact the fixed objects 10 of different thicknesses through self-adjustment.
[0028] The pressure plate 52 is used to transmit the force of the locking bolt 50 and the adjustable drive arm 51 to the fixed object 10, and cooperates with the lower frame 32 to achieve clamping. Its structure is plate-shaped and located in the clamping space inside the opening 4. It is fixedly connected to the lower part of the adjustable drive arm 51 to increase the contact area with the fixed object 10, so that the clamping force is distributed more evenly and the fixed object 10 is not damaged due to force concentration.
[0029] According to the above design, when assembling the anti-fall rope 1 installation structure, first align the opening 4 of the clamping body 3 with the fixed object 10, so that the fixed object 10 is inserted into the space between the upper frame 31 and the lower frame 32. Then operate the adjustable drive arm 51. Since its upper part is hinged to the upper frame 31, rotating the adjustable drive arm 51 can drive the lower pressure plate 52 to rotate and contact the surface of the fixed object 10, thereby achieving pre-clamping of the fixed object 10. At the same time, the length or angle of the adjustable drive arm 51 can be adjusted according to the thickness of the fixed object 10 to ensure that the pressure plate 52 is in the correct position. Next, tighten the locking bolt 50 that is threaded to the upper frame 31, so that its lower end gradually pushes the pressure plate 52. Under the pushing force of the locking bolt 50 and the support of the adjustable drive arm 51, the pressure plate 52, together with the lower frame 32, applies clamping force to the fixed object 10 until the fixed object 10 is firmly clamped.
[0030] The bottom surface of the pressure plate 52 and the top surface of the lower frame 32 are provided with anti-slip structures 6. The purpose of this design is to increase the friction between the pressure plate 52, the lower frame 32 and the fixed object 10, to prevent relative sliding between the installation structure and the fixed object 10, and to ensure the stability of the clamping and fixing. The anti-slip structure 6 is constructed with raised textures, stripes or dotted protrusions, and is integrally formed with the bottom surface of the pressure plate 52 and the top surface of the lower frame 32, so that the anti-slip structure 6 can be firmly attached to the contact surface. This design allows the anti-slip structure 6 to embed into the surface of the fixed object 10 or increase the frictional resistance during contact when the pressure plate 52 and the lower frame 32 clamp the fixed object 10, effectively resisting the lateral or axial tension generated when the fall arrest rope 1 is under force, preventing the installation structure from loosening and shifting, and thus ensuring the protective effect of the fall arrest rope 1.
[0031] A locking nut 7 is also provided on the locking bolt 50. The purpose of this design is to prevent the locking bolt 50 from loosening during long-term use or when subjected to vibration, ensuring that the clamping force of the pressure plate 52 on the fixed object 10 remains stable. The thread of the locking nut 7 matches the external thread of the locking bolt 50; the connection method is that after the locking bolt 50 is tightened to the preset position and the pressure plate 52 has completed clamping the fixed object 10, the locking nut 7 is screwed in from the upper end of the locking bolt 50 and tightened, so that it fits tightly against the top surface of the upper frame 31. This design creates an anti-loosening effect through the squeezing force between the locking nut 7 and the upper frame 31, counteracting the tendency of the bolt to loosen due to vibration or external force, avoiding weakening or failure of the clamping force, and ensuring the reliability of the connection between the installation structure and the fixed object 10.
[0032] The locking bolt 50 has a positioning head 8 at its bottom, and the pressure plate 52 has a positioning groove 9 that matches the positioning head 8. This design ensures that the pushing force of the locking bolt 50 on the pressure plate 52 is accurately transmitted, preventing relative slippage between the bolt bottom and the pressure plate 52 during the pushing process and ensuring the stability of the clamping action. The positioning head 8 is a hemispherical or cylindrical protrusion, integrally formed with the bottom of the locking bolt 50; the positioning groove 9 is a recessed structure that matches the shape of the positioning head 8, located on the top surface of the pressure plate 52 and corresponding to the position of the locking bolt 50. The connection method is such that when the locking bolt 50 is tightened and pushed downwards, its bottom positioning head 8 precisely embeds into the positioning groove 9 of the pressure plate 52, forming an accurate positioning fit. This allows the pushing force of the locking bolt 50 to act perpendicularly on the pressure plate 52, preventing force deviation during the pushing process and ensuring that the pressure plate 52 and the lower frame 32 work together to apply a uniform clamping force to the fixed object 10, avoiding loosening due to force deviation.
[0033] The positioning head 8 is a conical structure with its tip pointing downwards. This design ensures that the pushing force of the locking bolt 50 on the pressure plate 52 is accurately and centrally transmitted, preventing relative slippage between the bottom of the bolt and the pressure plate 52 during the pushing process, thus ensuring the stability of the clamping action. The positioning head 8 is a conical structure with its tip pointing downwards, integrally formed with the bottom of the locking bolt 50; the positioning groove 9 is a conical recess that matches the shape of the conical positioning head 8, located on the top surface of the pressure plate 52 and corresponding to the position of the locking bolt 50. The connection method is such that when the locking bolt 50 is tightened and pushed downwards, its conical positioning head 8 precisely embeds into the conical positioning groove 9 of the pressure plate 52, forming a tight positioning fit. This allows the pushing force of the locking bolt 50 to act vertically and centrally on the pressure plate 52, preventing force deviation during the pushing process and ensuring that the pressure plate 52 and the lower frame 32 work together to apply a uniform clamping force to the fixed object 10, avoiding loosening due to force deviation.
[0034] The adjustable drive arm 51 is a telescopic arm structure, comprising a telescopic inner arm 510 and a telescopic outer arm 511 that are nested together. The purpose of this design is to allow the adjustable drive arm 51 to flexibly adjust its length to accommodate fixed objects 10 of different thicknesses, ensuring that the pressure plate 52 accurately contacts the fixed object 10 and achieves pre-clamping. The telescopic inner arm 510 has a rod-like structure, while the telescopic outer arm 511 has a hollow tubular structure; their dimensions are compatible. The connection method involves the telescopic inner arm 510 being fitted into the hollow cavity of the telescopic outer arm 511, forming a relatively sliding sleeve structure. The overall length of the adjustable drive arm 51 is adjusted by changing the sleeve length. This design allows the adjustable drive arm 51 to adapt to fixed objects 10 of different thicknesses without replacing components, ensuring that the pressure plate 52 always maintains good contact with the fixed object 10, providing a stable foundation for the subsequent pushing and clamping of the locking bolt 50, and expanding the applicable scenarios of the installation structure.
[0035] The outer side of the connecting frame 30 is provided with at least one hanging ring 2 for connecting the fall arrestor rope 1. The purpose of this design is to provide a dedicated connection point for the fall arrestor rope 1, ensuring a secure connection between the rope and the installation structure and achieving fall protection. The hanging ring 2 has a closed loop shape, adapted to the hook or connecting component of the fall arrestor rope 1; the connection method is to fix it to the outer side of the connecting frame 30 by welding or bolts, ensuring that the hanging ring 2 and the connecting frame 30 form a solid whole. This design eliminates the need for the fall arrestor rope 1 to be directly connected to the fixed object 10 or other components of the installation structure. By establishing a stable force-bearing connection point through the hanging ring 2, the tensile force borne by the fall arrestor rope 1 can be reliably transmitted, preventing the connection from detaching or being damaged, and ensuring safety during the protection process.
[0036] According to this embodiment, when assembling the anti-fall rope 1 installation structure, first align the opening 4 of the clamping body 3 with the fixed object 10 such as an H-beam or I-beam and insert it, so that the fixed object 10 is placed between the upper frame 31 and the lower frame 32. Then, adjust the length of the adjustable drive arm 51, which is formed by the telescopic inner arm 510 and the telescopic outer arm 511. Rotate the adjustable drive arm 51 to drive the pressure plate 52 to contact the top surface of the fixed object 10 to achieve pre-tightening. Then, tighten the locking bolt 50 that is threaded to the upper frame 31, so that its bottom tip faces upwards. The conical positioning head 8 is embedded in the positioning groove 9 of the pressure plate 52. The pressure plate 52 and the lower frame 32 work together to clamp and fix the object 10. Then, the locking nut 7 is tightened to fit the upper frame 31 to prevent the bolts from loosening. At this time, the anti-slip structure 6 on the bottom surface of the pressure plate 52 and the top surface of the lower frame 32 enhances the friction with the fixed object 10. Finally, the fall arresting rope 1 is connected to the hanging ring 2 on the outside of the connecting frame 30. This design achieves convenient installation, stable locking and wide applicability through the cooperation of various components, and can reliably ensure the safety of related work scenarios.
[0037] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
