Description

Technical Field

[0001] The invention relates to the technical field of guide rail commutators, in particular to an I-shaped guide rail commutator of an iron tower high-altitude anti-fall device. Background Art

[0002] With the rapid development of China's power industry, the voltage level of power transmission lines and the height of towers are constantly rising, and the complexity of maintenance and operation management is also increasing. Especially for the operation and maintenance of towers at high altitude, how to ensure the safety of operation and maintenance personnel has become the focus of industry attention. Although the power industry has introduced many technical means in recent years to improve the safety and operability of transmission towers, manual tower inspection is still one of the main ways of tower maintenance at this stage.

[0003] In order to improve the safety and convenience of maintenance work, transmission towers are usually equipped with anti-fall rail systems. Rigid anti-fall rails are generally laid along the longitudinal direction of the tower. These rails provide the necessary safety guarantee for operation and maintenance personnel when performing high-altitude climbing operations, allowing them to successfully complete tower climbing and related maintenance work with the help of the rails and matching foot spikes.

[0004] Traditional guide rail reversing devices are usually used for the connection and transition between vertical and horizontal guide rails, so that the fall arrester can switch between guide rails in different directions. However, the structural characteristics of some towers have caused the installation direction of the foot nails at some joints to change. In particular, at some key nodes, the reversing angle of the vertical guide rail is not horizontal and may require direction adjustment or rotation. In this case, traditional commutators are difficult to adapt to, and usually need to twist the vertical guide rail or disconnect the guide rail to complete the transition. However, this method can easily cause the fall arrester to become blocked or even stuck at the transition point, thereby increasing the risk to the operators. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The invention aims to provide an I-shaped guide rail commutator for an iron tower high altitude anti-fall device, which solves the rotational commutation problem of the I-shaped rail for anti-falling of an iron tower of a power transmission line and can prevent the anti-fall device from falling out.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 8 As shown, this embodiment provides an I-shaped guide rail commutator for an anti-fall device for an iron tower, comprising: a first connecting structure 1, a turning guide rail structure 2 and a second connecting structure 3, wherein the first connecting structure 1 is located at one end of the turning guide rail structure 2, and the second connecting structure 3 is located at the other end of the turning guide rail structure 2, the first connecting structure 1 is used to connect to a section of a fixed guide rail 12 of the iron tower, and the second connecting structure 3 is used to connect to another section of a fixed guide rail 12 of the iron tower, and the first connecting structure 1 and the second connecting structure 3 are both able to rotate relative to the turning guide rail structure 2, and both ends of the turning guide rail structure 2 are provided with anti-out blocks 4. The turning guide rail structure 2 of this embodiment is responsible for the rotational reversal of the guide rail and the anti-fall safety device, and the two ends of the guide rail of the turning guide rail structure 2 are respectively connected to the fixed guide rail 12 of the iron tower through the first connecting structure 1 and the second connecting structure 3 to ensure its firmness and stability. At the same time, anti-out blocks 4 are designed at both ends of the turning guide rail structure 2 to prevent the anti-fall device from coming out due to misoperation, and only when the turning guide rail structure 2 is docked with the fixed guide rail can it pass smoothly. When the guide rail needs to be reversed, the operator drives the steering guide rail structure 2 to rotate by controlling the anti-fall safety device. After the steering guide rail structure 2 rotates to the right position, the guide rail reversing device completes the reversing operation.

[0033] Specifically, in the present embodiment, the steering guide rail structure 2 includes a steering sleeve 10 and a steering guide rail 11. The steering guide rail 11 is arranged on the steering sleeve 10. The shape of the steering guide rail 11 matches the shape of the tower fixed guide rail 12. Anti-exit blocks 4 are respectively arranged at both ends of the steering sleeve 10. The anti-exit blocks 4 are connected to the steering sleeve 10 by bolts. The steering guide rail 11 is located on one side of the steering sleeve 10, and the anti-exit block 4 is located on the other side of the steering sleeve 10. The gap between the anti-exit block 4 and the steering guide rail 11 can ensure the passage of the fall arrester. The anti-exit block 4 hinders the fall arrester when the steering guide rail structure 2 has not completed the steering, thereby preventing the fall arrester from escaping due to misoperation. When the steering guide rail structure 2 completes the steering, the anti-exit block 4 no longer blocks the fall arrester. The steering sleeve 10 is used to be connected with the first connecting structure 1 and the second connecting structure 3. A cavity is arranged inside the steering sleeve 10. The inner contour curve of the cross section of the cavity is circular. One end of the first connecting structure 1 and one end of the second connecting structure 3 are used to extend into the cavity.

[0034] In this embodiment, the structures of the first connecting structure 1 and the second connecting structure 3 are the same. The first connecting structure 1 and the second connecting structure 3 both include a connecting shaft 5, a connecting plate 8 and a clamp. The connecting plate 8 and the connecting shaft 5 are made of corrosion-resistant and wear-resistant materials to adapt to harsh outdoor environmental conditions and extend their service life. The connecting shaft 5 and the clamp are connected through the connecting plate 8. The outer contour of the cross section of the connecting shaft 5 is circular. One end of the connecting shaft 5 is located on the inner side of the connecting plate 8. The outer wall of the connecting shaft 5 is connected to the inner wall of the connecting plate 8. The other end of the connecting shaft 5 extends into the cavity of the steering sleeve 10. The gap between the connecting shaft 5 and the steering sleeve 10 can ensure that the connecting shaft 5 and the steering sleeve 10 can rotate relative to each other under the action of external force, and the friction between the connecting shaft 5 and the steering sleeve 10 can ensure that the connecting shaft 5 and the steering sleeve 10 are relatively fixed without the action of external force. The inner wall of the connecting plate 8 is provided with a plurality of guides along the circumference of the connecting plate 8. Groove 9, guide groove 9 is a through groove, guide groove 9 extends along the length direction of connecting plate 8, connecting plate 8 is annular, the outer diameter of connecting plate 8 is the same as the outer diameter of steering sleeve 10, the inner diameter of connecting plate 8 where guide groove 9 is not set is the same as the inner diameter of steering sleeve 10, guide groove 9 can be connected with the cavity of steering sleeve 10, guide groove 9 reduces the possibility of sand and dust directly entering the connecting shaft 5 area, while ensuring the smoothness of drainage; the clamp is used to connect with the fixed guide rail 12 of the iron tower, the clamp includes a first clamping plate 6 and a second clamping plate 7, one end of the first clamping plate 6 and one end of the second clamping plate 7 are both connected to one end of the connecting plate 8, the first clamping plate 6 and the second clamping plate 7 are used to clamp on both sides of the web of the fixed guide rail of the iron tower, the first clamping plate 6, the web of the fixed guide rail of the iron tower and the second clamping plate 7 are provided with connecting holes at corresponding positions, the first clamping plate 6, the web of the fixed guide rail of the iron tower and the second clamping plate 7 are connected by bolts.

[0035] This embodiment is mainly used for the rotation and reversing of the guide rail. When the guide rail needs to be reversed, it can be manually rotated to drive the steering guide rail structure 2 and the anti-fall device to rotate together to achieve the reversing purpose. The iron tower fixed guide rail 12 is connected to the steering guide rail structure 2 through the first connecting structure 1 and the second connecting structure 3. The middle steering guide rail structure 2 can meet the reversing requirements by manual rotation. The I-shaped guide rail commutator of the iron tower high-altitude anti-fall device of this embodiment is made of stainless steel to ensure its corrosion resistance. The steering guide rail structure 2 can rotate freely 360 degrees to meet the guide rail transition and reversing requirements of different angles of the iron tower longitudinal rigid guide rail.

[0036] For outdoor application scenarios, this embodiment solves the problem of dust accumulation by providing a guide groove 9 on the connecting plate 8. When there is mud and sand between the connecting shaft 5 and the steering sleeve 10, problems such as jamming or difficulty in operation may occur. By providing a guide groove 9, the mud and sand between the connecting shaft 5 and the steering sleeve 10 can be discharged, solving the problem of jamming or difficulty in operation caused by mud and sand accumulation. In addition, the design of the guide groove 9 has a self-cleaning effect, which can ensure the formation of a good drainage channel during natural precipitation, and use rainwater to flush and remove sand and dust deposits near the connecting shaft 5 to prevent jamming after accumulation to a certain extent. The guide groove 9 can not only greatly reduce the maintenance frequency, but also improve the reliability during long-term use in the field.

[0037] The present invention aims to solve the problem in the prior art that the fall arrester is stuck during commutation due to the complex structure of the tower and the change in the direction of the vertical guide rail. The present invention can flexibly adapt to the rotation and turning requirements of the vertical guide rails in different tower structures, realize the smooth transition of the fall arrester when passing through the turning point of the vertical guide rail, and ensure that the fall arrester maintains smooth operation on the guide rail. The present invention can effectively improve the safety of high-altitude workers in the operation, maintenance and inspection of power transmission towers, while reducing work delays caused by the jamming of the fall arrester, thereby improving work efficiency. The present invention can overcome the limitations of the existing fall arrester commutator used in complex tower structures, ensure the smooth progress of high-altitude operations, and reduce potential safety hazards.

[0038] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
