Abstract
Description
Technical Field
[0001] This utility model relates to the field of guide rail fall arrestor technology, and in particular to an I-beam guide rail connector. Background Technology
[0002] Fall arresters utilize the weight of a falling object for self-control, quickly braking and locking the falling object within a limited distance. During the construction and maintenance of power transmission lines and wind turbines, workers often need to climb ladders or equipment structures. By installing a fall arrester on a guide rail and connecting it to a safety rope, workers can quickly lock the fall arrester onto the guide rail when they lose their balance, thus preventing accidents.
[0003] I-beam aluminum alloy guide rails are commonly used in fall arresters. Their reasonable cross-sectional design provides strong load-bearing capacity, and their ease of processing has led to their widespread use. However, I-beam guide rails are typically supplied in 6-meter or 9-meter lengths. To reach higher positions, multiple I-beam guide rails need to be connected end-to-end for extension. However, the existing connection method uses two clamps to hold the I-beam guide rail together on both sides of its ribs, resulting in low connection strength and inconvenient installation.
[0004] Therefore, it is necessary to develop an I-beam guide rail connector to address the aforementioned defects. Utility Model Content
[0005] The purpose of this invention is to provide an I-beam guide rail connector that increases the connection strength of the I-beam guide rail and facilitates installation.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] This utility model relates to an I-beam guide rail connector, which connects two adjacent I-beam guide rails. It includes a connector body and fastening bolts. The connector body is a U-shaped cross-section profile structure. At least two through holes are provided on the side wall of the connector body. Correspondingly, through holes are also provided at both ends of the I-beam guide rail ribs. The U-shaped opening of the connector body snaps onto the ribs of two adjacent I-beam guide rails from the non-braking wing plate side. The fastening bolts pass through the through holes and the through holes for secure connection. An inwardly protruding locking head is provided at the top of the U-shaped opening of the connector body, and the locking head abuts against the ribs of the I-beam guide rails.
[0008] Furthermore, the connector body has a relief groove at the bottom of the U-shaped opening, and the cross-sectional profile of the relief groove matches the non-braking wing plate of the I-beam guide rail.
[0009] Furthermore, a rubber protrusion is provided on the end face of one side of the clamp head, and multiple rubber protrusions are equally spaced along the length direction of the clamp head, with the outer ends of the rubber protrusions abutting against the rib plate of the I-beam guide rail.
[0010] Furthermore, the main body of the rubber bump is a cylinder, a circular pit is provided on the end face of the clip, the root of the rubber bump is bonded to the circular pit, and the top of the rubber bump is set as a convex round head.
[0011] Furthermore, there are four through holes, and the connector body is connected to one end of the I-beam guide rail by two fastening bolts.
[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0013] This utility model of an I-beam guide rail connector, through its U-shaped cross-section profile structure, facilitates connection by snapping it onto the non-braking wing plate side of the I-beam guide rail. Compared to existing clamping methods, it eliminates the need for aligning the clamping plates on both sides against the mounting holes and does not affect the sliding of the fall arrestor on the braking wing plate. By adding an inwardly protruding locking head at the top of the U-shaped opening, two locking heads clamp the adjacent I-beam guide rail ribs, ensuring a secure and reliable connection. This utility model of an I-beam guide rail connector increases the connection strength of the I-beam guide rail and facilitates installation.
[0014] Furthermore, installing two fastening bolts between the head and the end of the I-beam guide rail increases the connection strength and prevents the upper I-beam guide rail from swaying left or right. By reasonably setting the cross-sectional profile of the clearance groove and the fitting clearance between it and the non-braking wing plate of the I-beam guide rail, when the clamping head presses against the rib plate of the I-beam guide rail, the top position of the clearance groove can also clamp onto the non-braking wing plate, forming effective clamping at both the top and bottom, making the connection more secure. By setting a rubber protrusion on the end face of one side of the clamping head, the rubber protrusion abuts against the rib plates of two adjacent I-beam guide rails. Even if the rib plates have thickness deviations, the two rib plates can be pressed simultaneously, and the rib plates can be aligned on the end face of the clamping head on the other side. By opening the circular pit on the end face of the clamping head, the root of the rubber protrusion is adhered to the circular pit, increasing the connection strength of the rubber protrusion and preventing it from falling off.

[0021] The core of this utility model is to provide an I-beam guide rail connector, which increases the connection strength of the I-beam guide rail and is easy to install.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0024] Refer to the attached diagram. Figure 1 This is a schematic diagram of the main structure of the I-beam guide rail connector in application state of this utility model; Figure 2 This is a three-dimensional structural diagram of the I-beam guide rail connector of this utility model in application state; Figure 3 This is a schematic diagram of the left side of the I-beam guide rail connector of this utility model; Figure 4 This is a schematic diagram of the front sectional view of the I-beam guide rail connector of this utility model.
[0025] In one specific implementation, such as Figures 1-4As shown, this utility model's I-beam guide rail connector connects two adjacent I-beam guide rails 6, specifically for connecting the beginning and end of two adjacent I-beam guide rails 6. This utility model's I-beam guide rail connector includes a connector body 1 and fastening bolts. The connector body 1 is a U-shaped profile structure, i.e., a long strip-shaped aluminum alloy part. At least two through holes 2 are provided on the side wall of the connector body 1, and corresponding through holes are also provided at the beginning and end of the ribs of the I-beam guide rails 6. The U-shaped opening of the connector body 1 engages with the ribs of two adjacent I-beam guide rails 6 from the non-braking wing side. The fastening bolts pass through the through holes 2 and the through holes and are then tightened with lock nuts for a secure connection. An inwardly protruding locking head 4 is provided at the top of the U-shaped opening of the connector body 1, and the locking head 4 abuts against the ribs of the I-beam guide rails 6.
[0026] By using a U-shaped cross-section profile structure for the connector body 1, it is easy to connect after snapping it onto the non-braking wing plate side of the I-beam guide rail 6. Compared to existing clamping methods, it eliminates the need for the clamping plates on both sides to be aligned with the mounting holes, and it does not affect the sliding of the fall arrestor on the braking wing plate. By adding an inwardly protruding locking head 4 at the top of the U-shaped opening, the two locking heads 4 clamp the ribs of adjacent I-beam guide rails 6, making the connection firm and reliable. This utility model of the I-beam guide rail connector increases the connection strength of the I-beam guide rail and facilitates installation.
[0027] Specifically, such as Figure 1 and Figure 2 As shown, there are four through holes 2, and the connector body 1 is connected to the I-beam guide rail 6 at one end by two of the fastening bolts. The fastening bolts are tightened with anti-loosening nuts.
[0028] By installing two fastening bolts between the ends of the I-beam guide rail 6, the connection strength can be increased, while preventing the upper I-beam guide rail 6 from swaying left or right.
[0029] In one specific embodiment of this utility model, such as Figures 2-4 As shown, the bottom end of the U-shaped opening of the connector body 1 is also provided with a clearance groove 3. The cross-sectional profile of the clearance groove 3 matches the non-braking wing plate of the I-beam guide rail 6. In fact, the cross-sectional profile of the clearance groove 3 is 0.5 to 0.7 mm larger than the non-braking wing plate, and the distance between the end faces of the two clips 4 and the outer wall of the rib plate is no more than 0.4 mm, so that it can be smoothly inserted into the end of the I-beam guide rail 6. Moreover, when the clips 4 press against the rib plate of the I-beam guide rail 6, the top position of the clearance groove 3 also clamps onto the non-braking wing plate.
[0030] By reasonably setting the cross-sectional profile of the relief groove 3 and the fitting gap between the non-braking wing plate of the I-beam guide rail 6, when the clamp 4 presses against the rib plate of the I-beam guide rail 6, the top position of the relief groove 3 can also be clamped on the non-braking wing plate, forming effective clamping at both the top and bottom, making the connection more secure.
[0031] In one specific embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a rubber protrusion 5 is provided on the end face of one side of the clamp 4. Multiple rubber protrusions 5 are evenly spaced along the length direction of the clamp 4, and the outer ends of the rubber protrusions 5 abut against the rib plate of the I-beam guide rail 6.
[0032] Specifically, the rubber bump 5 is made of hard rubber material with good weather resistance.
[0033] Specifically, such as Figure 3 and Figure 4 As shown, the main body of the rubber bump 5 is a cylinder, and a circular pit is provided on the end face of the clip 4. The root of the rubber bump 5 is bonded to the circular pit, and the top of the rubber bump 5 is set as a convex round head.
[0034] It should be noted that even if two adjacent I-beam guide rails 6 are selected with the same specifications, their cross-sectional dimensions may deviate within the tolerance range due to different processing batches or manufacturers. For example, the rib thickness of the two I-beam guide rails 6 may differ. In this case, if the connector body 1 is still made of rigid aluminum alloy, the thinner rib of the I-beam guide rail 6 may not be effectively clamped by the clamp 4.
[0035] By providing a rubber protrusion 5 on the end face of one side of the clamp 4, the rubber protrusion 5 abuts against the ribs of two adjacent I-beam guide rails 6. Even with thickness variations in the ribs, the two ribs can be pressed together synchronously, aligning them with the end face of the clamp 4 on the other side. By creating a circular pit on the end face of the clamp 4, the base of the rubber protrusion 5 adheres to the pit, increasing the connection strength of the rubber protrusion 5 and preventing it from falling off.
[0036] The installation process of this utility model's I-beam guide rail connector is as follows: Insert the connector body 1 into the top of the lower I-beam guide rail 6, ensuring that the clearance groove 3 mates with the non-braking wing plate of the I-beam guide rail 6. After positioning the upper I-beam guide rail 6, return the connector body 1 upwards to the connection point of the two I-beam guide rails 6, aligning the through hole 2 and the through hole. Insert the four fastening bolts, installing two fastening bolts on each I-beam guide rail 6, and install anti-loosening nuts. Gradually and alternately tighten each of the fastening bolts until the set torque requirement is met. Observe that the rubber protrusions 5 on the end face of the clamp 4 are effectively pressed against the rib plate of the I-beam guide rail 6, completing the installation.
[0037] In summary, this utility model of the I-beam guide rail connector, by using a U-shaped cross-section profile structure for the connector body 1, facilitates connection after snapping into the non-braking wing plate side of the I-beam guide rail 6. Compared to existing clamping methods, it eliminates the need for the clamping plates on both sides to be aligned with the mounting holes, and does not affect the sliding of the fall arrestor on the braking wing plate. By adding an inwardly protruding clamping head 4 at the top of the U-shaped opening, two clamping heads 4 clamp the ribs of adjacent I-beam guide rails 6, ensuring a secure and reliable connection. This utility model of the I-beam guide rail connector increases the connection strength of the I-beam guide rail and facilitates installation. Furthermore, by installing two fastening bolts between the I-beam guide rail 6 and its end, the connection strength is increased, while preventing the upper I-beam guide rail 6 from swaying left or right. By reasonably setting the cross-sectional profile of the clearance groove 3 and the fitting gap between it and the non-braking wing plate of the I-beam guide rail 6, when the clamping head 4 presses against the ribs of the I-beam guide rail 6, the top position of the clearance groove 3 can also grip the non-braking wing plate, forming effective clamping at both the top and bottom, resulting in a more secure connection. By providing a rubber protrusion 5 on the end face of one side of the clamp 4, the rubber protrusion 5 abuts against the ribs of two adjacent I-beam guide rails 6. Even with thickness variations in the ribs, the two ribs can be pressed together synchronously, aligning them with the end face of the clamp 4 on the other side. By creating a circular pit on the end face of the clamp 4, the base of the rubber protrusion 5 adheres to the pit, increasing the connection strength of the rubber protrusion 5 and preventing it from falling off.
