Description

Technical Field

[0001] This utility model relates to the field of high-altitude fall protection technology, and in particular to an embedded guide rail connection device and track. 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, guide rail fall arrest systems are generally used. Due to the complexity and diversity of passage areas and locations, the connection angles between guide rails in the system are not fixed. Therefore, various specifications (such as 30°, 45°, 90°, 120°, 180°) of connectors are needed to effectively connect the guide rail devices in the fall arrest system into a unified whole, achieving effective coverage of the fall arrest system in various working environments. However, in actual work sites, the included angles between guide rails are not the standard angles of 30°, 45°, 90°, etc. Some working conditions may even require the guide rails to rotate arbitrarily. How to effectively connect guide 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 embedded guide rail connection device and its usage method based on the on-site working conditions. This device enables effective connection of guide rails 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.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model 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 this patent. To better illustrate this embodiment, 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 this patent.

[0028] As a preferred embodiment of this utility model, this embodiment provides an embedded guide rail connection device, such as... Figure 1-6 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 this utility model, which can effectively connect different tracks and can be assembled and used according to the number of guide rails on site. The guide connector 32 is used to connect with the guide rail. Connector 4 is used to connect guide connector 32 to guide rail by bolts; 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 component 2 are constructed with mutually compatible T-shaped slide grooves 6, which are used for sliding installation of the follower; Four sets of locking devices 5 are symmetrically arranged on the two sides of the T-shaped slide groove on the rotating part 2. The locking devices 5 are used to allow the follower to pass only after the rotating part 2 has rotated to the point of docking with the guide rail. The hinge base 3, connector 4 and rotating component 2 are all made of stainless steel, aluminum alloy or titanium alloy.

[0029] 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 guide rail 7 is effectively connected to it by bolt connection through the connector 4.

[0030] The connector 4 is used to effectively connect the hinge base 3 and the guide rail 7. In a structure adapted to the guide rail, the connector is an H-shaped structure with grooves at its upper and lower ends for placing the guide rail 7 or the hinge guide connector 32, and then fixed by bolts.

[0031] In the above embodiments, such as Figure 4 and Figure 5 As shown, the locking device 5 includes a clearance groove 51 formed on the side of the T-shaped slide groove 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 T-shaped slide groove 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.

[0032] In some preferred embodiments, such as Figure 6 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 align with the guide rail, 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 align with another 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 the guide rail or sliding the rotating member 2 into another guide rail.

[0033] In other preferred embodiments, such as Figure 6As shown, the guide connector 32 is provided with a docking positioning groove 35, which is used to position the connector 4. The docking positioning groove 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 groove 35 is located on the outer periphery of the hinge plate 31.

[0034] In some embodiments, such as Figure 3 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 connecting cavities 42. One connecting cavity 42 is used for the guide connector 32 to be inserted and connected, and the other connecting cavity 42 is used for the guide rail 7 to be inserted and connected. 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.

[0035] In the embodiments of this utility model, 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 tracks in three or more directions, more hinged bases 3 can also be used.

[0036] In a preferred embodiment of this utility model, for easy and 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] As another preferred embodiment of this utility model, such as Figure 1 , Figure 7 and Figure 8 As shown, this embodiment provides an embedded track, including an embedded guide rail connection device 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 a T-shaped groove 6 that is 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.

[0039] As another preferred embodiment of this utility model, such as Figure 7 and Figure 8 As shown, this embodiment provides an installation method for an embedded track, characterized in that it includes: Install guide rails in the area requiring protection, determine the number of guide rails as needed, and determine the installation angle of each guide rail. After installing the rails at different angles, bring them together at a connection point. The guide rail connection point is connected using any of the above-described embedded guide rail connection devices.

[0040] The method of using this utility model includes: S1. Determine the upward direction of the guide rail system, and take the upward direction as the upward direction of the falling system; S2, Adjust the upward indicator of follower B ( Figure 1 Install it on guide rail 7 in the upward direction as determined by the arrow; 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 guide rail 7; ②The follower B slides into the rotating part 2 on the first guide rail 7. Based on the upward direction of the second guide rail 7, after ensuring that the follower B is still in the upward direction after entering the second guide rail 7, the rotating part 2 is rotated clockwise / counterclockwise to the direction of the second guide rail 7. 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.

[0041] 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 utility model. This is because this utility model is implemented in conjunction with the guide rail, and therefore only requires that their respective sliding grooves be identical. The external structure is not a functional structure implemented in this utility model, and therefore no explicit limitation is imposed on this part. For example, the external structure of the connector 4 in this utility model 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 utility model should be based on its role under the technical concept of this utility model. The description of this utility model should not be construed as a limitation on the external structure of each component or the internal structure that does not affect the function.

[0042] 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.
