Description

Technical Field

[0001] This invention relates to the field of high-altitude fall protection technology, and in particular to an adjustable-angle connecting device, combined track, and method for an external fall protection interlocking slide rail. Background Technology

[0002] In routine maintenance work at hydropower stations, we travel or conduct maintenance in various environments. Especially in high-risk environments involving vertical climbing, working near edges, traversing slopes, or alternating combinations of various working conditions, personnel frequently travel or work for extended periods in these environments, posing a risk of falling from heights. Therefore, it is crucial to provide effective safety protection for construction workers to ensure their safe passage or work.

[0003] Currently, to ensure safe passage for personnel in various working environments, interlocking slide rail fall arrest systems are generally used. Due to the complexity and diversity of passage areas and locations, the connection angle between the interlocking slide rails in the system is not a single fixed angle. Therefore, various specifications and models (30°, 45°, 90°, 120°, 180°) of connectors are needed to effectively connect the interlocking slide rail devices in the fall arrest system to form a complete system, achieving effective coverage of the fall arrest system in various working environments. However, in actual working conditions, the included angle between the interlocking slide rails is not the conventional 30°, 45°, 90°, etc. Some operating conditions may also involve situations where the interlocking slide rails need to rotate arbitrarily. How to effectively connect the interlocking slide rails at non-standard angles to achieve comprehensive coverage of the fall arrest system's working area is a problem that our maintenance personnel urgently need to solve.

[0004] Therefore, in order to solve the problem of continuous protection for personnel climbing and walking along the entire line in various traffic environments of existing hydropower stations, we have invented an external anti-fall interlocking slide rail angle adjustable connection device and usage method based on the on-site working conditions. This device enables effective connection of the interlocking slide rail at different angles, ensuring the safety of workers climbing or walking along the entire line in various high-risk environmental conditions, and guaranteeing work safety in complex environmental conditions. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable-angle connection device, combined track, and method for an external anti-fall interlocking slide rail. This device is primarily used for the effective connection of interlocking slide rail systems at any angle in complex working environments. It is used to connect interlocking slide rails to non-standard angle structures, enabling the fall-proof follower to safely change direction at any angle within the adjustable connection without derailment. This provides a safe and reliable barrier-free protection system for workers in high-risk environments such as vertical climbing, working near edges, traversing slopes, or alternating combinations of various working conditions. It achieves continuous safety protection for workers throughout their entire journey in complex and dangerous environments, safeguarding their lives and health.

[0026] To enable those skilled in the art to better understand the technical solutions of the present invention, the preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting the present patent. To better illustrate the embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting the present patent.

[0027] As a preferred embodiment of the present invention, this embodiment provides an angle-adjustable connection device for an external anti-fall interlocking slide rail, such as... Figure 1-5 As shown, it includes: Multiple hinged bases 3, each hinged base 3 includes a hinged plate 31 and a guide connector 32 fixedly connected to the edge of the hinged plate 31. The hinged base 3 is the main connector of the device of the present invention, which can effectively connect multiple guide rails. It can be assembled and used according to the number of interlocking slide rails on site. The guide connector 32 is used to connect with the guide rails. Connector 4 is used to connect guide connector 32 to guide rail; Rotating component 2 is rotatably connected to the hinge disks 31 of multiple hinge bases 3 via connecting pins 1, allowing relative rotation between the rotating component 2 and the hinge disks 31; wherein... The guide connector 32 and the rotating part 2 are equipped with interlocking slide rails 6 that are adapted to each other. The interlocking slide rails 6 are used for sliding installation of the follower. The rotating component 2 has four sets of locking devices 5 symmetrically arranged on both sides of the interlocking slide rail 6. The locking devices 5 are used to allow the follower to pass only after the rotating component 2 has rotated to the point of docking with the guide rail 7.

[0028] In the above embodiment, the guide connector 32 has a T-shaped groove 6 machined in the middle to facilitate the follower B to pass through the middle. The bottom of the T-shaped groove 6 is provided with a hexagonal countersunk mounting thread hole. The interlocking slide rail 7 is effectively connected to it by bolt connection through the connector 4.

[0029] The connector 4 is used to effectively connect the hinged base 3 and the guide rail 7. In a structure adapted to the guide rail, the connector is an H-shaped structure, with its upper and lower ends used to connect the interlocking slide rail 7 and the guide connector 32 respectively, and then fixed by bolts.

[0030] In the above embodiments, such as Figure 2 and Figure 3 As shown, the locking device 5 includes a clearance groove 51 formed on the side of the interlocking slide rail on the rotating member 2. A safety baffle 52 is rotatably installed in the clearance groove 51 via a rotating shaft 56. A torsion spring 53 is connected to the safety baffle 52. The torsion spring 53 is used to keep the safety baffle 52 in a state of extending out of the interlocking slide rail 6 when no external force is applied. It also includes a locking pin 54, which is inserted into the clearance groove 51. A spring 55 is sleeved on the locking pin 54. The spring 55 is used to allow the end of the locking pin 54 to extend out of the circumferential surface of the rotating member 2 when no external force is applied, and at the same time, it limits the safety baffle 52 so that the safety baffle 52 cannot rotate when subjected to external force. The locking pin 54 has a limiting part 57 in the middle for abutting against the safety baffle 52. When the locking pin 54 extends out of the end face of the rotating member 2, the limiting part 57 abuts against the end of the safety baffle 52, so that the safety baffle 52 cannot rotate when subjected to external force.

[0031] In some preferred embodiments, such as Figure 4 As shown, the guide connector 32 has guide grooves 33 on both sides to guide the locking pin 54 through. The guide grooves 33 have downwardly protruding bosses 34, so that when the rotating member 2 rotates to mate with the guide rail 7, the locking pin 54 is pressed down by the bosses 34, thus placing the safety baffle 52 in a state unrestricted by the locking pin 54. During the rotation of the rotating member 2 to mate with another guide rail, the guide groove 35 can quickly guide the locking pin 54 into the guide groove 35. Through the constant pressure of the bosses 34, the locking pin 54 moves downward, releasing the limiting effect of the limiting part 57 on the safety baffle 52. When the follower B slides, it can easily overcome the resistance of the torsion spring and then pass through the locking device 5, including sliding the rotating member 2 from one interlocking slide rail or from the rotating member 2 into another interlocking slide rail.

[0032] In other preferred embodiments, such as Figure 4 As shown, the guide connector 32 is provided with a docking positioning part 35, which is used to position the connector 4. The docking positioning part 35 is located on the back of the guide connector 32 to ensure a safe and reliable connection with the connector 4. The docking positioning part 35 is located on the outer periphery of the hinge plate 31.

[0033] In some embodiments, such as Figure 5 As shown, the connector 4 has a positioning part 41 in the middle. The positioning part 41 has the same cross-sectional structure as the guide connector 32. The positioning part 41 divides the connector 4 into two connection positions 42. One connection position 42 is used to connect with the guide connector 32, and the other connection position is used to connect with the interlocking slide rail. The positioning part 41 can play a positioning and limiting role during installation, so as to achieve quick installation. Its internal structure is the same as the cross-sectional structure of the guide connector 32, so that the sliding of the follower B is unobstructed after assembly.

[0034] For the stability of the connection of connector 4, such as Figure 5As shown, a docking limit pin 43 is also provided on the positioning part 41 of the connector 4, which is used to be inserted into the positioning hole on the guide rail 7 and the guide connector 32, and then the bolt is passed through the bolt hole 44 to connect and fix it.

[0035] In the embodiments of the present invention, 2-4 hinged bases 3 can be selected according to the needs of the site layout. Of course, if the site environment requires the arrangement of multiple guide rails in three or more directions, more hinged bases 3 can also be used.

[0036] In a preferred embodiment of the present invention, for ease of quick installation, disassembly and maintenance, the connector 4 and the guide connector 32 are detachably connected by bolts.

[0037] In a further preferred embodiment, the hinge plate 31 and the rotating member 2 are constructed as discs with the same cross-section, which facilitates manufacturing and makes it easier for the hinge plate 31 and the rotating member 2 to cooperate, especially facilitating the setting of the locking device 5.

[0038] like Figure 3 As shown, a groove can be opened between the two interlocking slide rails to facilitate the installation and sliding of the follower B.

[0039] As another preferred embodiment of the present invention, such as Figure 1 , Figure 6 and Figure 7 As shown, this embodiment provides an external anti-fall combination track, including an angle-adjustable connecting device for an external anti-fall interlocking slide rail provided in any of the above embodiments, and also includes a guide rail 7 connected to the guide connector 32. The guide rail 7 is constructed with an interlocking slide rail 6 adapted to the guide connector 32 and the rotating member 2. After the track system is assembled, the smoothness of the track system connection can be tested by rotating the rotating member 2.

[0040] As another preferred embodiment of the present invention, such as Figure 6 and Figure 7 As shown, this embodiment provides an installation method for an externally mounted fall-prevention combined track, characterized by comprising: Install guide rails 7 in the area requiring protection, determine the number of guide rails 7 according to the protection area, and determine the installation angle of each guide rail 7 according to the protection conditions. After installing guide rails at different angles, they are brought together to a connection point, and an angle-adjustable connecting device for an external anti-fall interlocking slide rail as described above is used at the connection point.

[0041] The method of using the present invention includes: S1. Determine the upward direction of the interlocking slide rail system, and take the upward direction as the upward direction of the falling system. S2. Install the follower B on the guide rail 7 with the upward marking as determined. S3, The process of the follower B moving from one guide rail 7 to another guide rail 7 includes: ①In the initial state, follower B is located on the first interlocking slide rail; ②The follower B slides into the rotating part 2 on the first guide rail 7. According to the upward direction of the second guide rail, after ensuring that the follower B is still in the upward direction after entering the second guide rail, the rotating part 2 is rotated clockwise / counterclockwise to the direction of the second guide rail. ③ After the rotating part 2 aligns with the guide connector 32 of the target hinge base 3, the locking pin 54 is pressed to the unlocked position under the external force of the guide connector 32, losing its locking function on the safety baffle 22. At this time, the safety baffle 22 rotates under the action of the follower B, overcoming the torsion of the torsion spring 53, allowing the follower B to pass freely on the rotating part 2. The locking pin 54 at the other end, since it is not subjected to external force, is locked under the action of the spring 55, restricting the rotation of the safety baffle 22, so that the safety baffle 22 is in the fully closed position, preventing the follower B from detaching from the rotating part 2 at this end, and ensuring the safety of the follower B when entering and exiting the rotating part 2.

[0042] The method of using the present invention includes: S1. Determine the upward direction of the external fall arrestor combination track, and take the upward direction as the upward direction of the fall arrestor system; S2, Adjust the upward indicator of follower B ( Figure 1 Install on guide rail 7 in the direction indicated by the arrow, following the determined upward direction; S3. The method for transferring the follower B from one guide rail 7 to another guide rail 7 includes: ①In the initial state, follower B is located on the first interlocking slide rail; ②The follower B slides into the rotating part 2 on the first guide rail 7. According to the upward direction of the second guide rail, after ensuring that the follower B is still in the upward direction after entering the second guide rail, the rotating part 2 is rotated clockwise / counterclockwise to the direction of the second guide rail. ③ After the rotating part 2 aligns with the guide connector 32 of the target hinge base 3, the locking pin 54 is pressed to the unlocked position under the external force of the guide connector 32, losing its locking function on the safety baffle 22. At this time, the safety baffle 22 rotates under the action of the follower B, overcoming the torsion of the torsion spring 53, allowing the follower B to pass freely on the rotating part 2. The locking pin 54 at the other end, since it is not subjected to external force, is locked under the action of the spring 55, restricting the rotation of the safety baffle 22, so that the safety baffle 22 is in the fully closed position, preventing the follower B from detaching from the rotating part 2 at this end, and ensuring the safety of the follower B when entering and exiting the rotating part 2.

[0043] The follower device B described in this invention is a protective installation device that is slidably installed on a track system during high-altitude operations. The worker's safety rope is connected to the follower device B, which slides within the guide rail, thus providing safety protection for the worker. The principle of the follower device B can be found in the utility model previously filed by the inventors in this application with publication number CN 222693895 U. Furthermore, this invention does not limit the specific structure of the slide rail. Based on the concept of this invention and known slide rail structures, it should be understood that any slide rail capable of employing a double-wheel interlocking rolling connection on both sides conforms to the technical concept of this invention.

[0044] It should be noted that the external structures of the rotating component 2, the guide connector 32, the connector 4, and the guide rail 7 are not specifically limited in the description of this invention. This is because this invention is implemented in conjunction with interlocking slide rails, so it is only necessary to ensure that the slide rail structures of each component are the same. Other structures are not functional structures implemented in this invention, and therefore no explicit limitations are imposed on these parts. For example, the external structure of the connector 4 in this invention can be the H-shaped structure already shown in this invention, or it can be other structural forms with an internal H-shaped structure, such as a tubular structure. Therefore, the understanding of each component in this invention should be based on its role under the technical concept of this invention, and the description of the embodiments of this invention should not be construed as a limitation on the specific structural form of each component in this invention.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention 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 the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
