Description

Technical Field

[0001] This utility model relates to a novel iron tower anti-fall device. Background Technology

[0002] With the rapid development of power systems, the construction and maintenance of power transmission towers have become increasingly important. Power transmission towers are typically quite tall, making safety paramount for workers performing tasks at height. Existing fall arrest devices primarily rely on pre-installed steel wire ropes. These ropes are constantly exposed to the outdoor environment, making them susceptible to damage from wind and sun, which can reduce their overall strength and compromise safety. Furthermore, most existing fall arrest devices clamp and brake from only one side, posing certain safety hazards.

[0003] Meanwhile, for rail-mounted fall arresters that use single-sided clamping and braking, clamps are required to fix them to the angle steel of the tower. However, this method has many shortcomings. The size of the clamps needs to be customized according to the tower type and tower drawings, which involves a huge amount of work. This is especially true for lines that were put into operation earlier, where drawings are difficult to find, making the design and installation of fall arresters even more difficult to implement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a new type of iron tower anti-fall device, which is applicable to various iron tower structures and simplifies the installation process.

[0005] The technical solution adopted in this utility model is:

[0006] A novel iron tower fall arrestor includes a clamping body, a pressure module, a flat iron, and a guide rail. The pressure module is G-shaped and includes a base plate, a left and right vertical plates connected to the left and right ends of the base plate, and a pressure plate connected to the top of the left vertical plate. The left vertical plate has a through hole for cooperating with the clamping body. The two clamping bodies are respectively attached to the two sides of the angle steel of the iron tower. The pressure module is inserted on the clamping body and the pressure plate is tightly fitted with the angle steel. A locking nut is provided at one end of the clamping body. The flat iron is fixedly installed between the other ends of the two clamping bodies. The guide rail is fixedly installed on the flat iron.

[0008] Furthermore, an arc-shaped opening is provided at the top of the right upright plate, which mates with a threaded section; the arc-shaped opening is inclined relative to the top surface of the right upright plate, and a thread is provided on the inner wall of the arc-shaped opening.

[0009] Furthermore, the pressure module is formed from sheet metal.

[0010] Furthermore, the main body section and the connecting section are set at a 135° angle, the connecting sections of the two clamping bodies are parallel, and the flat iron is fixedly installed between the two connecting sections by welding.

[0011] Furthermore, corresponding connection holes are provided on the flat iron and the guide rail, and they are connected by bolts and fixing nuts.

[0012] Furthermore, the flat iron is set at a 135° angle, with one end fixedly connected to the clamp body and the other end connected to the guide rail.

[0025] Example 1

[0026] As attached Figure 1-3 As shown, this embodiment provides a novel iron tower fall arrestor, including a clamping body 2, a pressure module 3, a flat iron 8, and a guide rail 4. Several sides of the clamping body 2 are cylindrical, and it is mounted on the angle steel 1 of the iron tower via the pressure module 3. The pressure module 3 is made of sheet metal and is G-shaped overall. It includes a base plate 302, a left vertical plate 303 and a right vertical plate 301 located at the left and right ends of the base plate 302, and a pressure plate 304 located at the top of the left vertical plate 303. A through hole 306 is provided on the left vertical plate 303. During installation, the two clamp bodies 2 are respectively attached to the two sides of the angle steel 1. Then, the pressure module 3 is installed on the clamp body 2 through the through hole 306, and the angle steel 1 and the clamp body 2 are positioned between the top of the pressure plate 304 and the right vertical plate 301. The angle of the pressure plate 304 and the right vertical plate 301 is adjusted using tools (such as wrenches) so that the angle steel 1 and the clamp body 2 are pressed between the pressure plate 304 and the right vertical plate 301. A locking nut 5 is set on the clamp body 2 and on the outside of the pressure module 3 to lock and fix the pressure module 3.

[0027] The clamping body 2 includes a main body section 201, a threaded section 202 located at one end of the main body section 201, and a connecting section 203 located at the other end of the main body section 201. The main body section 201 and the connecting section 203 are set at an obtuse angle of 135°. The main body section 201 is attached to the angle steel 1. The pressure module 3 and the locking nut 5 are both installed on the threaded section 202. The connecting sections 203 of the two clamping bodies are arranged opposite to each other and are parallel. The flat iron 8 can be fixedly installed between the two connecting sections 203 by welding. The guide rail 4 is fixedly connected to the flat iron 8.

[0028] An arc-shaped opening 305 is provided at the top of the right upright plate 301. This arc-shaped opening cooperates with the threaded section 202, which enables a tighter connection between the pressure module 3 and the clamping body 2, preventing loosening after installation. Preferably, the arc-shaped opening 305 is inclined relative to the top surface of the right upright plate 301 (that is, the inner wall of the arc-shaped opening 305 is not perpendicular to the right upright plate 301, but gradually slopes downward from the outside to the inside), and a thread is provided on the inner wall of the sliding opening 305. The arc-shaped opening 305 adopts a beveled thread design. When the arc-shaped opening 305 cooperates with the threaded section 202, the thread can further improve the connection stability between the two.

[0029] Corresponding connection holes are made on the flat iron 8 and the guide rail 4. The guide rail 4 and the flat iron 8 are fixedly connected together by bolts 6 and fixing nuts 7 through the connection holes.

[0030] Guide rail 4 is a rigid steel rail type, and adjacent guide rails are connected by either a rigid connection or a flexible connection. When a rigid connection is used, adjacent guide rail sections 4 are fixedly connected by a thickened steel plate, which is time-consuming and labor-intensive to install, increasing the construction difficulty and installation period. This embodiment also provides another connection method, namely a flexible connection, as shown in the attached figure. Figure 4 As shown, the flexible connection includes a steel strip 9 disposed between two adjacent guide rails 4. Corresponding connection interfaces are provided on the rail surface of the guide rail 4 and at the end of the steel strip 9. The steel strip 9 is fixedly connected to the guide rail 4 using bolts. (See attached diagram) Figure 5 This embodies another type of flexible connection structure. Slots 10 are provided on the corresponding sides of the two guide rails 4. The two ends of the steel strip 9 are respectively inserted into the slots 10 of the corresponding guide rails 4, and then the steel strip 9 is fixedly connected to the guide rails 4 using bolts.

[0031] The steel strips, with their flexibility and high strength, allow for flexible adjustment between guide rails within a certain range. This accommodates slight deviations in the tower structure and changes in installation position, while ensuring the strength and safety of the connection. Quickly connecting segmented guide rails reduces installation time and improves construction efficiency.

[0032] The guide rail 4 is coated with a high-performance isocyanate-based insulating and anti-corrosion coating. The material meets the requirements of abrasion resistance ≤30mg, no powdering or cracking after 1000h accelerated aging test, and tear strength reduction ≤10%. After coating, the weather resistance of the guide rail can be greatly increased.

[0033] Example 2

[0034] This embodiment is an improvement on embodiment 1, only changing the structure of the flat iron 8, so that the protection device can meet different installation forms.

[0035] As attached Figure 6 , 7 As shown, in this embodiment, the flat iron 8 is designed at a 135° angle, with one end connected to the connecting section 203 of the clamp body 2, and the other end provided with a connecting hole for connecting to the guide rail 4. This allows the installation angle of the guide rail 4 to be changed to meet different environmental requirements.

[0036] The installation position of the pressure module 3 in this invention is adjustable, eliminating the need for custom drawings. The clamping body 2 can be installed onto the angle steel 1 simply by adjusting the position of the pressure module 3, making it suitable for various tower structures and simplifying the installation process. The pressure module 3 features a detachable design, allowing for quick disassembly via the locking nut 5. This enables rapid replacement of pressure modules of different sizes without additional tools, simplifying installation and disassembly. Furthermore, a weather-resistant coating is applied to the surface of the guide rail 4, enhancing its corrosion resistance and durability in harsh environments.

[0037] 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 the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
