Description

Technical Field

[0001] This invention relates to a climbing protection device for angle steel towers and its usage method, which is particularly suitable for use in climbing operations on angle steel towers of power transmission lines and belongs to the technical field of power transmission maintenance sites. Background Technology

[0002] Existing fall arrestor rails on angle iron towers of power transmission lines suffer from high installation costs and safety hazards. Currently, most towers do not use fall arrestor rails. When climbing these towers, one method is to use a safety harness and backup rope to repeatedly install and remove safety protection while climbing. This method is time-consuming, unsafe, and physically demanding. Another method involves workers attaching two conductor protection hooks to their safety harnesses, connected to the hooks using a pole harness and backup rope. The first conductor protection hook is installed on the angle iron, and the worker climbs a certain distance before installing the second hook. Due to the unique structure of the conductor hooks, they can be removed from the hooked object from a distance. With the second hook in place, the worker removes the first hook, repeating this process until the work position is reached. The same procedure is used when descending the tower. However, when climbing upwards after installing the wire protection hook, the personnel were above the installation position of the wire protection hook, that is, the use of the safety belt was "low-hanging and high-using", which violated the safety regulations that "the hook or rope of the safety belt should be hung on a sturdy and secure component or a steel wire rope specifically for hanging safety belts, and should be used in a high-hanging and high-using manner". This method is a violation.

[0003] To prevent similar situations from occurring, there is an urgent need for a climbing protection device for angle steel towers to improve the safety of workers climbing angle steel towers of power transmission lines, ensuring that personnel do not lose their safety protection and guaranteeing personal safety. It should also meet the requirements for static load testing and impact testing of fall arrestor self-locking devices. Summary of the Invention

The clamping mechanism holds one side of the L-shaped main rib angle iron 32, and the baffle mechanism abuts against the other side of the main rib angle iron 32, thereby protecting the device and firmly fixing it to the angle iron tower. The baffle mechanism includes a slide rod 22 with one end installed on the rear clamping plate 4. Multiple equidistant holes 23 are opened along the length of the slide rod 22. A positioning chamber 24 is fitted on the slide rod 22. A mounting seat 26 is provided on the positioning chamber 24. A baffle 27 is installed on the side of the mounting seat 26.

[0013] Preferably, a space pad 29 is provided between the grip 2 and the body 1. Part of the grip 2 has a hollow design. The grip 2 and the space pad 29 are connected to the body 1 through a screw. There are plug-in parts between the grip 2 and the space pad 29, and between the space pad 29 and the body 1.

[0014] Preferably, filling holes are provided on both the front and rear sides of the front clamping plate 3 and on the side of the rear clamping plate 4 facing the front clamping plate 3. When anti-slip polyurethane is poured on the front and rear sides of the front clamping plate 3 and the rear clamping plate 4, the filling holes are filled with polyurethane material, which forms an integral part with the outer polyurethane material to ensure the firmness of the outer polyurethane layer.

[0015] The second objective of this invention is to provide a method for using an angle iron tower climbing protection device, which is characterized by including the following steps:

[0016] 1) The operator holds a steel tower climbing protection device in each hand, and fixes one end of the backup protection rope and the pole strap to the two hook plates 5 respectively. The other end of the backup protection rope and the pole strap is connected to the operator.

[0017] 2) Press down button 13, the connecting rod 10 disengages from the two pins 19, drag the front clamping plate 3 away from the rear clamping plate 4, so that one side of the main rib angle iron 32 is located between the front clamping plate 3 and the rear clamping plate 4. Release button 13, the front clamping plate 3 returns to its original position under the action of the tension spring 12, so that the front clamping plate 3 and the rear clamping plate 4 hold one side of the main rib angle iron 32.

[0018] 3) Adjust the position of the baffle 27 so that the baffle 27 abuts against the other side of the main reinforcing angle iron 32, thereby fixing the protective device to the main reinforcing angle iron 32;

[0019] 4) When the operator climbs further up, press down button 13 and pull back handle 2. At this time, the front clamp 3 and the rear clamp 4 are in the open state, so that the device is removed from the current position. After reaching a higher position, release button 13. The front clamp 3 is reset under the action of tension spring 12, so that the front clamp 3 and the rear clamp 4 clamp the angle steel tower 32.

[0020] 5) Operators use both hands to operate the equipment, changing the operation cycle according to the climbing height.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In this invention, the body and cover plate are fixed together by screws. The two side edges of the cover plate overlap with the body, forming a space for the connecting rod to move. The purpose of this structure is to prevent the connecting rod from transmitting force to the body and causing deformation when it is under stress, thereby increasing the mechanical strength of the body. It also prevents the body from cracking open when the force reaches a certain level, thus losing its protective function.

[0023] 2. The present invention has a connecting shaft at one end of the front clamping plate, and one end of the connecting shaft extends into the connecting rod. The connection between the front clamping plate and the connecting rod is reinforced by the connecting shaft, and one end of the connecting shaft is inserted into the connecting rod for fixation. When the front clamping plate is subjected to force and it is transmitted to the connecting shaft, the surface of the force is increased to the part of the connecting shaft that is inserted into the connecting rod, thereby effectively increasing the connection strength between the connecting rod and the front clamping plate and preventing the cross section at the connection between the stressed connecting rod and the front clamping plate from breaking.

[0024] 3. The connecting rod of the present invention has arc-shaped protrusions on both the upper and lower sides, and arc-shaped grooves that cooperate with the arc-shaped protrusions are provided at the corresponding positions of the main body, so that the connecting rod is connected to the main body in an expanded manner, preventing the connecting rod from coming off the main body when the operator falls.

[0025] 4. The hook plate of this invention is connected to the safety belt's arm strap and the backup safety rope respectively. The left and right hand protection devices are cyclically fixed on the main reinforcement of the tower, providing uninterrupted protection for the workers.

[0026] 5. The double-pin design of this invention provides a backup pin in case of single-pin damage, increasing the safety factor. Driven by the button, the front and rear clamping plates retract via springs, locking the tower material. Simultaneously, the pins and equidistant pin holes engage to achieve a locking function, preventing malfunction of the front and rear clamping plates.

[0027] 6. The rear clamping plate of this invention is fixedly installed on the cover plate to prevent the protective device from sliding on the iron tower when the front and rear clamping plates are clamped together, because both the front and rear clamping plates can move.

[0028] 7. After the front and rear clamps of this invention lock the tower material together, the baffle can prevent the clamps from sliding off laterally when subjected to an outward moving force. The baffle position is also adjustable, making it suitable for different types of tower materials.

[0029] 8. After the front and rear clamps of this invention lock the tower material, the connecting rod is located inside the main body. The impact force generated by a person falling is applied to the connecting rod and ultimately transmitted to the main body due to the structural fit, preventing the impact force from acting only on the connecting rod. Under the lever principle, the connecting rod deforms and breaks at the section in contact with the main body. This structure increases the mechanical strength of the protection device.

[0030] 9. After the front and rear clamps of this invention lock the tower material, the impact force generated by a person falling acts on the cover plate. To prevent the cover plate from slipping, the main body is provided with a top block at the rear end of the cover plate, thereby reducing the shear force on the bolts connecting the cover plate and the main body and increasing the mechanical strength of the protection device.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention. Example

[0043] This embodiment provides a climbing protection device for an angle iron tower, as shown in the attached diagram. Figure 1-11The system includes two identical protective devices, one for each hand. Each device is held in the left and right hands. The main body 1 has a clamping mechanism on one side and a handle 2 on the other. Inside the main body 1 is a drive mechanism that opens and closes the clamping mechanism. The clamping mechanism includes a front clamping plate 3 and a rear clamping plate 4. Filling holes are provided on the front and rear surfaces of the front clamping plate 3 and on the side of the rear clamping plate 4 facing the front clamping plate 3. When anti-slip polyurethane is poured onto the front and rear surfaces of the front clamping plate 3 and the rear clamping plate 4, the filling holes are filled with polyurethane material, forming an integral whole with the outer polyurethane layer to ensure its firmness. The lower surface of the main body 1 has a hook plate 5 for connecting the safety belt's armband or backup safety rope. The hook plate 5 connects to the safety belt's armband and backup safety rope, respectively. Simultaneously, the left and right hand protective devices are cyclically and fixedly installed on the main reinforcement of the tower, providing uninterrupted protection for the workers. A cover plate 6 is installed on the main body 1 to improve its mechanical strength, and one end of the rear clamping plate 3 is fixedly installed on the cover plate 6.

[0044] To increase strength, the hook plate 5 is an integral structure with the main body 1, and the hook plate 5 is provided with a buckle.

[0045] The driving mechanism of this embodiment includes a connecting rod 10 partially disposed within the main body 1. A spring groove 11 is provided along the length of the connecting rod 10, and a tension spring 12 is provided in the spring groove 11. One end of the tension spring 12 is fixed to the connecting rod 10, and the other end is fixed to the cover plate 6. A button 13 for controlling the connecting rod 10 is installed on the main body 1. A connecting shaft 28 is provided in the front clamping plate 3. One end of the connecting shaft 28 extends into the connecting rod 10. A pressure rod 17 is provided below the button 13. A pin base 18 is installed at one end of the pressure rod 17 after passing through the main body 1 and extending to the outside of the main body 1. Two pins 19 are installed on the pin base 18. Multiple pin holes 20 that cooperate with the pins 19 are provided along the length of the connecting rod 10. A reset spring 21 is provided between the button 13 and the main body 1. The extension and retraction of the tension spring 12 is controlled by button 13. Button 13 is connected to pin holder 18 via the lower end of pressure rod 17. Pin holder 18 is equipped with two sets of pins 19, which can engage with equidistant pin holes 20 to lock the connecting rod 9 in a certain position and control the length of tension spring 12. The double pin design is to provide a backup pin in case of single pin failure, increasing the safety factor. Driven by button 13, the front and rear clamping plates retract via springs, locking the tower material. Simultaneously, the engagement of pins 19 and equidistant pin holes 20 achieves a locking function, preventing malfunction of the front and rear clamping plates.

[0046] In this embodiment, the front clamping plate 3 is provided with a connecting shaft 28 at one end, and one end of the connecting shaft 28 extends into the connecting rod 10. The front clamping plate 3 can rotate around the connecting shaft 28. In order to increase the connection strength between the connecting rod 10 and the front clamping plate 3 and prevent the cross-section of the connection between the stressed connecting rod 10 and the front clamping plate 3 from breaking, the connection between the two is reinforced by the connecting shaft 28. One end of the connecting shaft 28 is inserted into the connecting rod 10 for fixation. When the front clamping plate 3 is subjected to force and it is transmitted to the connecting shaft 28, the surface of the force is increased to the part of the front end of the connecting shaft 28 that is inserted into the connecting rod 10.

[0047] To prevent the connecting rod 10 from disengaging from the track of the body 1, a limiting screw 14 is installed at one end of the connecting rod 10 to prevent the connecting rod 10 from disengaging from the body 1.

[0048] In this embodiment, the main body 1 has slots 7 on both the upper and lower sides facing the clamping mechanism. The cover plate 6 has flanges 8 on both the upper and lower sides that cooperate with the slots 7. After the slots 7 and flanges 8 are engaged, the main body 1 and the cover plate 6 are fixed together by screws. The main body 1 and the cover plate 6 are fixed by screws. The flanges 8 on both sides of the cover plate overlap with the main body to form the movable space of the connecting rod 10. The purpose of this structure is to prevent the connecting rod from transmitting force to the main body and causing deformation when it is under stress, thereby increasing the mechanical strength of the main body and preventing the main body from cracking when the force reaches a certain level, thus losing its protective function.

[0049] After the front and rear clamps lock the tower material, the connecting rod 10 is located inside the body 1. The impact force generated by the fall of a person acts on the connecting rod 10, and due to the structural fit, it is finally transmitted to the cover plate 6 and the body 1, preventing the impact force from acting only on the connecting rod 10. Under the lever principle, the connecting rod 10 deforms and breaks at the section in contact with the body 1. This structure increases the mechanical strength of the protection device.

[0050] After the front and rear clamps lock the tower material, the impact force generated by a person falling acts on the cover plate 6. To prevent the cover plate 6 from slipping, the body 1 has a top block 9 at the rear end of the cover plate 6 to reduce the shear force on the bolts connecting the cover plate 6 and the body 1 and increase the mechanical strength of the protection device.

[0051] In this embodiment, the cover plate 6 is provided with a sloping fixed platform 31. The rear clamping plate 4 is fixedly installed on the fixed platform 31. The fixed platform 31 can prevent the rear clamping plate 4 from rotating and prevent the protective device from sliding on the iron tower when the front and rear clamping plates are clamped.

[0052] The other end of the connecting rod 10 is provided with arc-shaped protrusions 15 on both the upper and lower sides, and the corresponding position of the body 1 is provided with arc-shaped grooves 16 that cooperate with the arc-shaped protrusions 15, so that the connecting rod 10 is connected to the body 1 in an expanded manner, preventing the connecting rod from coming off the body when the operator falls.

[0053] In this embodiment, a baffle mechanism is installed on the rear clamping plate 4 to prevent the device from sliding and falling off laterally during clamping. The clamping mechanism holds one side of the L-shaped main rib angle iron 32, and the baffle mechanism abuts against the other side of the main rib angle iron 32, thereby protecting the device and firmly fixing it on the angle iron tower. The baffle mechanism includes a slide rod 22 with one end installed on the rear clamping plate 4. Multiple equidistant holes 23 are opened along the length of the slide rod 22. A positioning chamber 24 is fitted on the slide rod 22. A mounting seat 26 is provided on the positioning chamber 24. A baffle 27 is installed on the side of the mounting seat 26. A pressing handle 25 is provided on the mounting seat 26. The pressing handle 25 is connected to an insertion rod, which is used in conjunction with the equidistant holes 23.

[0054] Because the slide bar 22 has equidistant holes 23, the baffle 27 can be fixed on any of the equidistant holes 23. After the front and rear clamps lock the tower material, when subjected to an outward moving force, the baffle 27 can prevent the clamps from sliding and falling off laterally. At the same time, the position of the baffle 27 is adjustable, making it suitable for different types of tower materials.

[0055] A spacer block 29 is provided between the handle 2 and the body 1. Part of the handle 2 has a hollow design to reduce the overall weight. The spacer block 29 provides effective space for personnel to grip the handle 2. The handle 2 and the spacer block 29 are connected to the fall arrestor body 1 by a screw. There are also plug-in parts between the handle 2 and the spacer block 29, and between the spacer block 29 and the fall arrestor body 1. The screw and plug-in parts improve the overall mechanical strength of the combination of the handle 2 and the fall arrestor body 1.

[0056] The method of using an angle iron tower climbing protection device according to this embodiment includes the following steps:

[0057] 1) The operator holds a steel tower climbing protection device in each hand, and fixes one end of the backup protection rope and the pole strap to the two hook plates 5 respectively. The other end of the backup protection rope and the pole strap is connected to the operator.

[0058] 2) Press down button 13, the connecting rod 10 disengages from the two pins 19, drag the front clamping plate 3 away from the rear clamping plate 4, so that one side of the main rib angle iron 32 is located between the front clamping plate 3 and the rear clamping plate 4. Release button 13, the front clamping plate 3 returns to its original position under the action of the tension spring 12, so that the front clamping plate 3 and the rear clamping plate 4 hold one side of the main rib angle iron 32.

[0059] 3) Adjust the position of the baffle 27 so that the baffle 27 abuts against the other side of the main reinforcing angle iron 32, thereby fixing the protective device to the main reinforcing angle iron 32;

[0060] 4) When the operator climbs further up, press down button 13 and pull back handle 2. At this time, the front clamp 3 and the rear clamp 4 are in the open state, so that the device is removed from the current position. After reaching a higher position, release button 13. The front clamp 3 is reset under the action of tension spring 12, so that the front clamp 3 and the rear clamp 4 clamp the angle steel tower 32.

[0061] 5) Operators use both hands to operate the equipment, changing the operation cycle according to the climbing height.

[0062] This invention provides safety protection for workers climbing angle iron towers. It provides workers with "high-hanging, low-use" safety protection measures that meet the regulations, effectively improving the efficiency of workers climbing towers, reducing the labor intensity of workers, and thus avoiding unnecessary losses caused by human error.
