Abstract
Description
Technical Field
[0001] This utility model relates to the field of guide rail fall arrestor technology, and in particular to an integrated bending guide rail commutator. Background Technology
[0002] During the construction and maintenance of power transmission and distribution lines and wind turbines, workers often need to climb iron towers or tower sections to perform their work. By installing a fall arrestor on a guide rail and connecting it to a safety rope, workers can climb the tower. When a worker loses their balance, their weight can quickly lock the fall arrestor onto the guide rail, thus preventing accidents.
[0003] However, since high-altitude operations often involve working in more than one direction, sometimes requiring lateral movement to another location, it necessitates switching between horizontal and vertical tracks. To avoid the safety hazard of the fall arrestor detaching from the previous guide rail before moving to the next during the transition, a guide rail commutator is required. Existing commutator panels are often welded to reduce manufacturing costs, which carries the risk of weld cracking during use.
[0004] Therefore, it is necessary to develop an integrated bent guide rail commutator to address the aforementioned shortcomings. Utility Model Content
[0005] The purpose of this utility model is to provide an integrated bent guide rail commutator, which adopts a commutator plate seat formed by sheet metal integral processing, with high structural strength and good safety performance.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] This utility model relates to an integrated bending guide rail commutator, comprising a commutator disc base, a rotation guide mechanism, and a guide rail block. The base plate of the commutator disc base has four connecting lugs evenly distributed around its circumference. The U-shaped openings of the connecting lugs facing upwards engage with longitudinally or laterally arranged guide rail ribs. Through holes for fastening bolts are provided on the sidewalls of the connecting lugs. The base plate of the commutator disc base and the connecting lugs are integrally formed using sheet metal bending. The guide rail block is rotatably connected to the base plate of the commutator disc base via the rotation guide mechanism, and the guide rail block can overlap with the guide rail.
[0008] Furthermore, a baffle strip is provided on the outer periphery of the bottom plate of the commutator disc base between the two connecting lugs. The four baffle strips are evenly distributed around the circumference and are perpendicular to the bottom plate of the commutator disc base and integrally formed.
[0009] Furthermore, the top edge of the baffle strip is flush with the top surface of the guide rail block.
[0010] Furthermore, the rotation guide mechanism includes steering ribs, two of which are symmetrically arranged about the central axis of the commutator disc base plate. Both ends of the steering ribs are fixedly connected downward to the commutator disc base plate. The guide rod of the steering rib is an arc-shaped bar, the center of which is located on the central axis of the commutator disc base plate, and the circumferential angle of the arc-shaped bar is greater than 100 degrees. The rib of the guide rail block has a guide hole at the position of the arc-shaped bar.
[0011] Furthermore, the cross-section of the arc bar is circular, the guide hole is an oblong hole, and the long side of the oblong hole is parallel to the length direction of the guide rail block.
[0012] Furthermore, the two ends of the steering guide rail facing downwards are configured as screw sections. The screw sections pass through the mounting holes on the commutator disc base plate. The screw sections are threaded with an inner lock nut and an outer lock nut. The inner lock nut and the outer lock nut are respectively locked to the inner side wall and the outer side wall of the commutator disc base plate.
[0013] Furthermore, the outer lock nut presses the spring washer tightly against the outer wall of the commutator disc base plate.
[0014] Furthermore, it also includes a pad, which is placed between the inner wall of the connecting lug and the outer wall of the guide rail rib.
[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0016] This utility model features a one-piece bent guide rail commutator. The base plate and connecting lugs are integrally formed using sheet metal bending, resulting in higher connection strength compared to welding and avoiding the risk of weld cracking. The commutator disc base, also integrally formed from sheet metal, offers high structural strength and excellent safety performance.
[0017] Furthermore, by setting a baffle strip between the two connecting lugs, the end face of the guide rail block that has not yet rotated to its position can be blocked and protected, preventing the fall arrestor from falling off during the rotation of the guide rail block. By reasonably setting the height of the baffle strip, it can effectively prevent fall arrestors of various specifications from falling off. The baffle strip is integrally formed with the sheet metal base plate of the commutator disc seat, giving it sufficient blocking strength. The guide rail block is guided by a steering rib, which has a simple and exposed structure, making it easy to observe and promptly detect and repair any problems. By symmetrically setting two steering ribs, the guide rail block is connected at two points, ensuring sufficient connection strength. By using a waist-shaped guide hole, the jamming of the guide rail block during rotation is reduced, ensuring smooth rotation of the guide rail block. The steering rib is fixed by threading an inner lock nut and an outer lock nut on the screw section, and the height position of the arc bar can be flexibly adjusted to make the top surface of the guide rail block flush with the guide rail strip. By adding a pad between the inner wall of the connecting lug and the outer wall of the guide rail rib, the width of the U-shaped opening of the connecting lug is increased, which facilitates sheet metal processing and forming; the commutator disc seat, pad, and steering rib are manufactured using stainless steel, which can achieve better corrosion resistance.

[0026] The core of this utility model is to provide an integrated bending guide rail commutator, which adopts a commutator plate seat formed by sheet metal integral processing, with high structural strength and good safety performance.
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] Refer to the attached diagram. Figure 1 This is a three-dimensional structural diagram of the integrated bent guide rail commutator of this utility model; Figure 2 This is a three-dimensional structural diagram of the integrated bent guide rail commutator of this utility model from another angle; Figure 3 This is a schematic diagram of the main structure of the integrated bent guide rail commutator of this utility model; Figure 4 This is a three-dimensional structural diagram of the commutator disk base of this utility model; Figure 5 This is a three-dimensional structural diagram of the steering rib rail of this utility model. Figure 6 This is a three-dimensional structural diagram of the guide rail rotating block of this utility model.
[0030] In one specific implementation, such as Figures 1-6 As shown, this utility model's integrated bent guide rail commutator includes a commutator disc base 1, a rotation guide mechanism, and a guide rail rotating block 5. Four connecting lugs 101 are evenly distributed around the circumference of the base plate of the commutator disc base 1. The upward-facing U-shaped openings of the connecting lugs 101 engage with the ribs of the longitudinally or transversely arranged guide rails 8. That is, the four connecting lugs 101 correspond to the four guide rails 8, forming a cross shape. Two sets of through holes 102 are provided on the sidewalls of the connecting lugs 101 for fastening bolts 3, with two fastening bolts 3 threaded through each connecting lug 101 for locking. The base plate of the commutator disc base 1 and the connecting lugs 101 are integrally formed using sheet metal bending. The guide rail rotating block 5 is rotatably connected to the base plate of the commutator disc base 1 through the rotation guide mechanism. The guide rail rotating block 5 can overlap with the guide rails 8, allowing the fall arrestor to switch positions between the longitudinally and transversely arranged guide rails 8.
[0031] The base plate and connecting lug 101, integrally formed by sheet metal bending, offer higher connection strength compared to welding, avoiding the risk of weld cracking. This utility model's integrally bent guide rail commutator uses a commutator disc base integrally formed from sheet metal, resulting in high structural strength and good safety performance.
[0032] In one specific embodiment of this utility model, such as Figures 1-4 As shown, baffle strips 104 are also provided on the outer periphery of the bottom plate of the commutator disc base 1 between the two connecting lugs 101. The four baffle strips 104 are evenly distributed around the circumference and are perpendicular to the bottom plate of the commutator disc base 1 and integrally formed.
[0033] Specifically, such as Figures 1-4 As shown, the top edge of the baffle strip 104 is flush with the top surface of the guide rail rotating block 5.
[0034] By setting a baffle strip 104 between the two connecting lugs 101, the end face of the guide rail block 5 that has not yet rotated to the correct position can be blocked and protected, preventing the fall arrestor from falling off during the rotation of the guide rail block 5; by reasonably setting the height of the baffle strip 104, it can effectively prevent fall arrestors of various specifications from falling off; the baffle strip 104 is integrally formed with the sheet metal of the bottom plate of the commutator plate seat 1, so that it has sufficient blocking strength.
[0035] In one specific embodiment of this utility model, such as Figure 1 and Figures 3-6 As shown, the rotation guide mechanism includes two steering ribs 4, which are symmetrically arranged around the central axis of the commutator disc base 1. Both ends of the steering ribs 4 are fixedly connected downwards to the commutator disc base 1. They can be welded or riveted together, and the fixing point is located between two connecting lugs 101. The guide rod portion of the steering rib 4 is an arc-shaped bar, which is parallel to the commutator disc base 1. The center of the arc-shaped bar is located on the central axis of the commutator disc base 1, and the circumferential angle of the arc-shaped bar is greater than 100 degrees. The rib of the guide rail block 5 has guide holes 501 at the positions of the arc-shaped bars.
[0036] The guide rail block 5 is guided by the steering rib 4, which has a simple and exposed structure, making it easy to observe and allowing for timely detection and maintenance of any problems. The two steering ribs 4 are symmetrically arranged, providing a two-point connection to the guide rail block 5, ensuring sufficient connection strength.
[0037] Specifically, such as Figure 5 and Figure 6 As shown, the cross-section of the arc bar is circular, and the guide hole 501 is an oblong hole, with the long side of the oblong hole being parallel to the length direction of the guide rail rotating block 5.
[0038] By making the guide hole 501 an oblong hole, the jamming of the guide rail rotating block 5 is reduced, ensuring the smooth rotation of the guide rail rotating block 5.
[0039] In one specific embodiment of this utility model, such as Figure 2 and Figure 5 As shown, the two ends of the steering guide rail 4 facing downward are set as screw sections 401. The screw sections 401 pass through the mounting holes 103 on the bottom plate of the commutator disc base 1. The screw sections 401 are threaded with inner lock nuts 6 and outer lock nuts 7. The inner lock nuts 6 and outer lock nuts 7 are respectively locked to the inner side wall and outer side wall of the bottom plate of the commutator disc base 1.
[0040] Specifically, such as Figure 2 As shown, the outer lock nut 7 presses the spring washer tightly against the outer wall of the commutator plate base 1.
[0041] By threading the inner lock nut 6 and the outer lock nut 7 onto the screw section 401 to fix the steering rib rail 4, the height position of the arc bar can be flexibly adjusted so that the top surface of the guide rail block 5 is flush with the guide rail strip 8.
[0042] In one specific embodiment of this utility model, the integrated bending guide rail commutator further includes a pad 2, which is placed between the inner wall of the connecting lug 101 and the outer wall of the guide rail 8 rib. That is, there are 8 pads 2.
[0043] Specifically, the thickness of the pad 2 is not less than 8 mm. The commutator disc mount 1, the pad 2, and the steering guide rail 4 are all made of stainless steel, which provides good corrosion resistance.
[0044] By adding a pad 2 between the inner wall of the connecting lug 101 and the outer wall of the guide rail 8 rib plate, the width of the U-shaped opening of the connecting lug 101 is increased, which facilitates sheet metal processing and forming; the commutator disc seat 1, pad 2 and steering rib 4 are manufactured using stainless steel materials, which can achieve better corrosion resistance.
[0045] The working principle of this integrated bending guide rail reversing device is as follows: For example, when transferring a fall arrestor from a longitudinally positioned guide rail 8 to a transversely positioned guide rail 8, first rotate the guide rail rotating block 5 to the vertical direction, aligning it with the two longitudinal guide rails 8. The fall arrestor is then dragged to the middle position of the guide rail rotating block 5 using a safety rope. The guide rail rotating block 5 is then manually rotated; after rotating 90 degrees around the steering rib 4, the guide rail rotating block 5 aligns with the transversely positioned guide rail 8. The fall arrestor can then be dragged to the transversely positioned guide rail 8 for lateral movement.
[0046] In summary, this utility model's integrated bent guide rail commutator, through the use of sheet metal bending to integrally form the base plate and connecting lugs 101, achieves higher connection strength compared to welding, avoiding the risk of weld cracking. This utility model's integrated bent guide rail commutator uses a sheet metal integrally formed commutator disc base, resulting in high structural strength and good safety performance. Furthermore, by setting a baffle strip 104 between the two connecting lugs 101, the end face of the guide rail block 5, which has not yet rotated to its position, can be blocked and protected, preventing the fall arrestor from falling off during rotation with the guide rail block 5. By reasonably setting the height of the baffle strip 104, it can effectively prevent the fall arrestor of various specifications from detaching. The baffle strip 104 is integrally formed with the sheet metal base plate of the commutator disc base 1, giving it sufficient blocking strength. The use of steering ribs 4 to guide the guide rail block 5 is simple in structure and exposed, making it easy to observe and allowing for timely detection and maintenance of any problems. By symmetrically arranging two steering ribs 4 and connecting the guide rail swivel block 5 at two points, sufficient connection strength is ensured. The guide hole 501 is a waist-shaped hole, reducing the jamming during rotation of the guide rail swivel block 5 and ensuring smooth rotation. The steering rib 4 is fixed by threaded connection of the inner lock nut 6 and outer lock nut 7 on the screw section 401, allowing for flexible adjustment of the height of the arc-shaped bar, ensuring the top surface of the guide rail swivel block 5 is flush with the guide rail strip 8. A pad 2 is added between the inner wall of the connecting lug 101 and the outer wall of the guide rail strip 8 rib plate, increasing the U-shaped opening width of the connecting lug 101, facilitating sheet metal forming. The commutator disc seat 1, pad 2, and steering rib 4 are manufactured using stainless steel, achieving good corrosion resistance.
