Description

Technical Field

[0001] This utility model relates to the field of high-altitude work equipment technology, and in particular to a fall-prevention rigid guide rail. Background Technology

[0002] With the increasing demand for high-altitude operations, fall arrest devices are widely used in construction, equipment maintenance, power line repair, bridge inspection, and other scenarios to ensure the safety of workers. Among them, rigid rail fall arrest systems are gradually becoming a commonly used safety protection method in high-altitude operations due to their stable structure, high load-bearing capacity, and high safety. Existing rigid fall arrest rails typically include metal rails fixed to the building or structure, trolley assemblies that slide along the rails, and safety ropes for connecting workers.

[0003] However, existing devices generally suffer from problems such as complex installation structures, poor adaptability, uneven trolley operation on the track, easy track deformation, and difficult maintenance, affecting safety and convenience of use. When the guide rail has been used for a long time and bears a high weight, the high longitudinal and lateral pressure causes deformation at the guide rail connection, directly damaging the guide rail function. In this case, the fall arrestor fails, posing a fatal threat to the lives of construction workers. Utility Model Content

[0004] The main purpose of this utility model is to provide a fall-proof rigid guide rail, which aims to improve the stability of the guide rail connection and prevent the fall-proof guide rail from deforming.

[0005] To achieve the above objectives, this utility model proposes a fall-prevention rigid guide rail, comprising multiple guide rail segments connected end to end and a connecting structure. Each guide rail segment is provided with a web plate and a wing plate that are perpendicular to each other. The wing plate is used to install an external fall arrestor.

[0006] The web plate is provided with an abutment plate at the end away from the wing plate. The abutment plate and the wing plate are arranged in parallel. The web plate is provided with a plurality of first connecting holes at the end near the abutment plate. The connecting structure is provided with a connecting plate on both sides of the web plate. The connecting plate is provided with a plurality of second connecting holes in the array of the plurality of first connecting holes, for connecting the web plates of two adjacent guide rail sections to the connecting plates on both sides at the same time.

[0007] One end of the connecting plate is provided with an abutting structure that abuts against the abutting plate to ensure that adjacent webs are on the same plane.

[0008] In one embodiment of this application, the abutting plate includes a stabilizing portion and an abutting portion. The stabilizing portion is disposed on the side of the abutting plate away from the wing plate and is arranged parallel to the wing plate. The abutting portion is arc-shaped and recessed at the end of the stabilizing portion facing the wing plate. The abutting portion is connected to the web plate.

[0009] The abutting structure abuts against the abutting part.

[0010] In one embodiment of this application, a connecting portion is provided on both sides of the abutment plate, the two connecting portions are parallel to each other, and the connecting portions are parallel to the web plate;

[0011] The end of the abutting structure away from the abutting part is connected to the connecting part, and the two connecting plates wrap around the abutting plate.

[0012] In one embodiment of this application, the abutting structure has an extension section protruding along the direction from the wing plate to the abutting plate, and a locking plate protruding along the extension direction of the stabilizing part at one end of the extension section away from the abutting structure. Adjacent locking plates are staggered, and a plurality of locking structures are arranged in an array facing the abutting plate. The locking structures are arranged along the direction from the wing plate to the abutting plate.

[0013] In one embodiment of this application, the two ends of the stabilizing part are symmetrically arrayed with a plurality of positioning parts, each of the positioning parts corresponding to a locking structure, the locking structure passing through the positioning part and abutting against the abutting plate.

[0014] By adopting the above technical solution, this utility model has the following advantages:

[0015] 1. In order to ensure that the rigid guide rail can stably connect to the fall arrester and avoid deformation at the weak points of the guide rail connection, the two adjacent rigid guide rail sections are connected to each other through a connecting structure. Structurally, the rigid guide rail section includes a wing plate for connecting the fall arrester and a web plate for strengthening the guide rail section and facilitating the locking connection between the two adjacent guide rail sections. One side of the web plate is connected to the surface of the wing plate, making the cross-section of the guide rail section T-shaped, which can ensure the structural strength of the rigid guide rail connection and prevent the guide rail from deforming.

[0016] 2. A stop plate is provided parallel to the wing plate on the side of the web plate away from the wing plate. The web plate, wing plate, and stop plate are connected to each other, making the cross-section of the guide rail section I-shaped. The stop plate is thickened, which can effectively improve the structural strength of the guide rail section. Multiple first connection holes are opened at the end of the web plate near the stop plate, so that the fall arrestor can pass normally through the connection point of the two guide rail sections. The connection structure includes at least two connecting plates. The two connecting plates are sandwiched on both sides of the web plate. Multiple second connection holes are opened on the connecting plates. By using the two connecting plates to sandwich the two connected web plates, the connecting plates can restrict the two web plates to be on the same plane. The two connecting plates can ensure the stability of the connection. The two connecting plates are fixed with screws. The two connecting plates can act as gaskets for each other, which can avoid damage to the web plate caused by the screws and effectively reduce maintenance costs. One side of the connecting plate can abut against the stop plate. The stop plate and the connecting plate support each other, which can increase the structural strength of the entire rigid guide rail.

[0017] 3. The end of the connecting plate away from the wing plate and the side away from the web plate has an abutting structure relative to the abutting plate. The abutting structure wraps around the abutting plate to strengthen the structural strength of the entire guide rail section connection and to ensure that the two web plates are in the same plane.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] Reference Figures 1 to 2 To achieve the above objectives, this utility model proposes a fall-prevention rigid guide rail, which includes multiple guide rail segments 1 connected at their tails and a connecting structure 3. Each guide rail segment 1 is provided with a web plate 12 and a wing plate 11 that are perpendicular to each other. The wing plate 11 is used to install an external fall arrestor.

[0026] The web plate 12 is provided with an abutment plate 2 at the end away from the wing plate 11. The abutment plate 2 and the wing plate 11 are arranged in parallel. The end of the web plate 12 near the abutment plate 2 is provided with a plurality of first connecting holes 13. The connecting structure 3 is provided with a connecting plate 4 on both sides of the web plate 12. The connecting plate 4 is provided with a plurality of second connecting holes 41 on the array of the plurality of first connecting holes 13, which are used to connect the web plate 12 of two adjacent guide rail sections 1 to the connecting plates 4 on both sides at the same time.

[0027] One end of the connecting plate 4 is provided with an abutting structure 5 that abuts against the abutting plate 2, which is used to ensure that adjacent web plates 12 are on the same plane.

[0028] In order to ensure that the rigid guide rail can stably connect to the fall arrester and avoid deformation at the weak connection of the guide rail, the two adjacent rigid guide rail segments 1 are connected to each other by the connecting structure 3. Structurally, the rigid guide rail segment 1 includes a wing plate 11 for connecting the fall arrester and a web plate 12 for strengthening the guide rail segment 1 and facilitating the locking connection between the two adjacent guide rail segments 1. One side of the web plate 12 is connected to the surface of the wing plate 11, so that the cross section of the guide rail segment 1 is T-shaped, which can ensure the structural strength of the rigid guide rail connection and prevent the guide rail from deforming.

[0029] Abutment plate 2 is provided parallel to the wing plate 11 on the side of the web plate 12 away from the wing plate 11. The web plate 12, wing plate 11, and abutment plate 2 are interconnected, making the cross-section of the guide rail section 1 I-shaped. The abutment plate 2 is thickened, which can effectively improve the structural strength of the guide rail section 1. Multiple first connection holes 13 are provided at the end of the web plate 12 near the abutment plate 2, so that the fall arrester can pass normally through the connection point of the two guide rail sections 1. The connection structure 3 includes at least two connection plates 4, which are sandwiched between the two sides of the web plate 12. Multiple second connection holes 13 are provided on the connection plates 4. The connection hole 41 is sandwiched between two connected web plates 12 by two connecting plates 4. The connecting plates 4 can restrict the two web plates 12 so that the two connected flanges 11 are on the same plane. The two connecting plates 4 can ensure the stability of the connection. The two connecting plates 4 can be fixed with screws. The two connecting plates 4 can act as gaskets for each other, which can avoid damage to the web plates 12 caused by the screws and effectively reduce maintenance costs. One side of the connecting plate 4 can abut against the abutment plate 2. The abutment plate 2 and the connecting plate 4 support each other and can increase the structural strength of the entire rigid guide rail.

[0030] The connecting plate 4 is located at one end away from the wing plate 11 and the side away from the web plate 12. It is provided with an abutting structure 5 relative to the abutting plate 2. The abutting structure 5 is wrapped around the abutting plate 2 to strengthen the structural strength of the connection of the entire guide rail section 1 and to ensure that the two web plates 12 can be in the same plane.

[0031] See also Figures 1 to 2In one embodiment of this application, the abutting plate 2 includes a stabilizing part 21 and an abutting part 24. The stabilizing part 21 is disposed on the side of the abutting plate 2 away from the wing plate 11 and is parallel to the wing plate 11. The abutting part 24 is arc-shaped and recessed at the end of the stabilizing part 21 facing the wing plate 11. The abutting part 24 is connected to the web plate 12.

[0032] The abutting structure 5 abuts against the abutting part 24.

[0033] The stabilizing part 21 is parallel to the wing plate 11, and the entire abutting plate 2 has a symmetrical structure along the web plate 12, which can ensure the structural stability and structural strength of the guide rail section 1. The abutting part 24 is a concave arc-shaped structure, which can be used to increase the contact area between the abutting plate 2 and the abutting structure 5, so that the interaction force between the connecting plate 4 and the abutting plate 2 is greater, which can further improve the structural strength of the guide rail section 1 and prevent deformation at the connection of the guide rail section 1.

[0034] See also Figure 2 In one embodiment of this application, a connecting part 23 is provided on both sides of the abutment plate 2, the two connecting parts 23 are parallel to each other, and the connecting parts 23 are parallel to the web plate 12.

[0035] The end of the abutting structure 5 away from the abutting part 24 is connected to the connecting part 23, and the two connecting plates 4 are wrapped around the abutting plate 2.

[0036] The connecting part 23 is provided with both sides of the abutting plate 2, and the abutting structure 5 is wrapped around the connecting part 23, which can further increase the contact area. Since the connecting part 23 is a straight segment parallel to the web plate 12, the end of the abutting structure 5 away from the wing plate 11 is connected to the connecting plate 4. At the same time, the thickness of the abutting structure 5 is uniform, which can ensure the connection stability and avoid damage to the abutting structure 5 itself, effectively improving the service life and enhancing the user experience.

[0037] See also Figures 1 to 2 In one embodiment of this application, the abutting structure 5 has an extension section 51 protruding along the direction from the wing plate 11 to the abutting plate 2. The end of the extension section 51 away from the abutting structure 5 has a locking plate 6 protruding along the extension direction of the stabilizing part 21. Adjacent locking plates 6 are staggered and multiple locking structures 7 are arranged in an array facing the abutting plate 2. The locking structures 7 are arranged along the direction from the wing plate 11 to the abutting plate 2.

[0038] An extension section 51 is provided at one end of the abutment structure 5 away from the wing plate 11 and the abutment part 24 along the extension direction of the connecting part 23. The end of the extension section 51 is provided with a locking plate 6 along the stabilizing part 21. A locking structure 7 is provided with the locking plate 6 toward the stabilizing part 21. The locking structure 7 (bolt structure) can stabilize the structure of the entire guide rail, ensure that the two guide rail sections 1 are fully engaged and connected, and prevent the two guide rail sections 1 from shifting. Both connecting plates 4 are provided with locking plates 6, and the two locking plates 6 are staggered and connected to each other. The locking structure 7 passes through both locking plates 6. The locking plates 6 on the two connecting plates 4 support each other, which can further improve the structural strength. The extension section 51 can make the entire structure more stable.

[0039] See also Figures 1 to 2 In one embodiment of this application, the stabilizing part 21 has a plurality of positioning parts 22 symmetrically arranged at both ends, and each positioning part 22 corresponds to a locking structure 7. The locking structure 7 passes through the positioning part 22 and abuts against the abutting plate 2.

[0040] The stabilizing part 21 has a positioning part 22 evenly provided at the end of the guide rail section 1. The positioning part 22 is a positioning groove structure. In this application, the positioning groove has a mating hole on the connecting part 23. The locking structure 7 will abut against the abutting plate 2 through the positioning part 22. This structure can further play the role of preventing displacement and can effectively connect two adjacent guide rail sections 1 to each other, ensuring the stability of the connection between the two guide rail sections 1.
