Abstract
Description
Technical Field
[0001] This application relates to the technical field of anti-climbing devices, and in particular to an anti-climbing device for a steel pipe tower. Background Technology
[0002] If someone climbs the steel pipe tower during the operation of a power transmission line, it will affect the safety of the line operation and personal safety. Anti-climbing devices are safety devices for the operation of power transmission lines, playing a safety protection role, preventing the hidden danger of theft and loss of the identification signs on the steel pipe tower, and ensuring the safety of line operation.
[0003] Currently, relevant anti-climbing devices for steel pipe towers include, for example, Chinese Patent No. CN204266665U, which discloses an anti-climbing device for steel pipe towers, comprising a semi-circular tube, another semi-circular tube, a crescent-shaped plate, a lock, and a steel pipe tower. One end of the semi-circular tube and the other semi-circular tube are connected to the outer surface of the crescent-shaped plate via a hinge. A protruding edge is provided on the outer surface of the other end of the semi-circular tube and the other semi-circular tube. A locking hole is provided at the lower part of the protruding edge of the semi-circular tube and the other semi-circular tube, and the lock closes the locking hole of the protruding edge of the semi-circular tube and the other semi-circular tube. The crescent-shaped plate is connected to the corresponding side wall of the steel pipe tower ladder to partially cover the ladder. Therefore, a novel anti-climbing device for steel pipe towers is proposed. Utility Model Content
[0004] To improve the anti-climbing effect of the anti-climbing device, simplify installation, and eliminate the need for dismantling during maintenance, this application provides an anti-climbing device for steel pipe towers.
[0005] Firstly, this application provides an anti-climbing device for steel pipe towers, employing the following technical solution:
[0006] An anti-climbing device for a steel pipe tower includes a ladder fixed along the height of the steel pipe tower, a main frame, and an installation mechanism. The main frame is fixedly connected to the ladder via the installation mechanism. A protective mechanism for anti-climbing is also fixed on the side of the main frame away from the steel pipe tower. The protective mechanism has a movable window that can rotate in the horizontal direction and a locking component that enables the movable window to function as an anti-climbing device. The movable window is opposite to the position of the ladder in the vertical direction for climbing.
[0007] By adopting the above technical solution, the main frame is fixed to the ladder through the installation mechanism, enabling rapid installation and fixation. When the movable window is perpendicular to the length of the ladder, the locking component locks the movable window, and the protective mechanism is in a protective state, preventing unauthorized personnel from climbing. When maintenance is required, maintenance personnel open the locking component and rotate the movable window to a position parallel to the length of the ladder. At this time, the protective mechanism is in a maintenance state, facilitating maintenance personnel to climb the steel pipe tower for maintenance without removing the anti-climbing device.
[0008] Optionally, the installation mechanism is located in the middle section of the main frame. The installation mechanism includes a clamp and a connecting bolt. A nut is threaded onto the connecting bolt. The clamp is located on the side of the main frame near the ladder. Both ends of the clamp have through holes. The main frame has mounting holes opposite to the through holes. The connecting bolt passes through both the through holes and the mounting holes and is threaded onto the nut, so that the ladder is clamped between the clamp and the main frame.
[0009] By adopting the above technical solution, when it is necessary to install the anti-climbing device on the ladder, the anti-climbing device is horizontally hoisted to a suitable height by hoisting equipment. Then, the workers connect the clamp and the main frame with connecting bolts and tighten the nuts to make the clamp hold the ladder, thereby fixing the position of the main frame on the ladder.
[0010] Optionally, the protective mechanism includes at least two supports fixedly connected to the main frame. The two supports are fixedly positioned relative to each other at both ends of the main frame. The supports extend away from the steel pipe tower, and the ends of the two supports away from the main frame are bent towards each other. A rotating shaft is rotatably mounted on the end of each support away from the main frame. The end of the rotating shaft away from the support is rotatably connected to the main frame. A movable window is fixed on each rotating shaft. The middle section of the movable window is fixedly connected to the rotating shaft. The locking assembly is located on the side of two adjacent movable windows that are close to each other.
[0011] By adopting the above technical solution, the space formed between the two supports is opposite to the vertical position of the ladder. Therefore, when the movable window between the supports is kept horizontal and locked by the locking component, it is in a protective state, and unauthorized personnel cannot continue to climb up the ladder. When maintenance is required, the maintenance personnel can open the locking component and rotate the movable window vertically to create a space that allows them to continue climbing up, thus facilitating maintenance.
[0012] Optionally, the main frame has a limiting groove for inserting a rotating shaft on the side near the bracket, and the bracket has an installation groove opposite to the limiting groove. The two ends of the rotating shaft are respectively inserted into the limiting groove and the installation groove and are rotatably connected to the limiting groove and the installation groove.
[0013] By adopting the above technical solution, the two ends of the rotating shaft are respectively inserted into the limiting groove and the mounting groove, so that the rotating shaft will not detach from the main frame and the support in the vertical direction, and ensure that the rotating shaft can rotate stably.
[0014] Optionally, the locking assembly includes hanging rings fixed to one side wall of two adjacent movable windows that are close to each other, with a lock head installed between the two hanging rings.
[0015] By adopting the above technical solution, when the lock head locks the two hanging rings together, the movable window cannot rotate around the rotation axis, thereby achieving the locking effect; when the maintenance personnel open the lock head with the key, the two hanging rings are no longer locked, thereby allowing the movable window to rotate.
[0016] Optionally, a protective plate is also fixed to the side of the main frame near the side wall of the steel pipe tower, and the protective plate has an inclined surface parallel to the side wall of the steel pipe tower.
[0017] By adopting the above technical solutions, the protective plate further improves the protective effect of the anti-climbing device and reduces the risk of unauthorized personnel climbing it.
[0018] Optionally, there may be multiple protective plates, and each of the multiple protective plates may be fixed with barbed wire to prevent climbing.
[0019] Optionally, two anti-slip blocks are fixed at intervals on one side wall of the main frame near the ladder. The anti-slip blocks are arranged opposite to the clamps. When the clamps are pressed against the ladder, the anti-slip blocks are pressed against the two sides of the ladder.
[0020] By adopting the above technical solutions, barbed wire further improves the protective effect of anti-climbing devices.
[0021] In summary, this application has the following beneficial effects:
[0022] 1. The main frame is fixed to the ladder via the installation mechanism, enabling quick installation and fixation. When the movable window is perpendicular to the length of the ladder, the locking component locks the movable window, and the protective mechanism is in a protective state to prevent unauthorized personnel from climbing. When maintenance is required, the maintenance personnel open the locking component and rotate the movable window to a position parallel to the length of the ladder. At this time, the protective mechanism is in a maintenance state, facilitating maintenance personnel to climb the steel pipe tower for maintenance.
[0023] 2. The space formed between the two supports is opposite to the vertical position of the ladder. Therefore, when the movable window between the supports is kept horizontal and locked by the locking component, it is in a protective state, and unauthorized personnel cannot continue to climb up the ladder. When maintenance is required, the maintenance personnel can open the locking component and rotate the movable window vertically to create a space that allows them to continue climbing up, thus facilitating maintenance.
[0024] 3. The protective plate further enhances the protective effect of the anti-climbing device, reducing the chances of unauthorized personnel climbing it. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0033] This application discloses an anti-climbing device for steel pipe towers.
[0034] Reference Figure 1 and Figure 2 An anti-climbing device for a steel pipe tower includes a steel pipe tower 1 vertically fixed to the ground. The cross-section of the steel pipe tower 1 is octagonal. A vertically arranged ladder 11 is fixed on one side wall of the steel pipe tower 1. A main frame 2 is installed on the ladder 11. An installation mechanism 3 is provided on the side of the main frame 2 closest to the ladder 11. The main frame 2 is fixedly connected to the ladder 11 through the installation mechanism 3. A protective mechanism 4 is provided on the side of the main frame 2 away from the ladder 11. The protective mechanism 4 can prevent unauthorized personnel from continuing to climb the ladder 11, thereby ensuring the normal operation of the steel pipe tower 1.
[0035] Reference Figure 2 and Figure 3The installation mechanism 3 is located in the middle section of the main frame 2, which fixes the ladder 11 to the middle position of the main frame 2. The installation mechanism 3 includes a clamp 31 and two connecting bolts 32. Both ends of the clamp 31 are provided with through holes 311 for the connecting bolts 32 to pass through. The middle section of the main frame 2 is also provided with mounting holes 21 that are one to one with the through holes 311. After the middle position of the clamp 31 is pressed against the side wall of the ladder 11, the connecting bolts 32 pass through both the through holes 311 and the mounting holes 21. The installation mechanism 3 also includes a nut 33 that is threadedly connected to the connecting bolts 32. By installing the nut 33 onto the connecting bolts 32 and pressing the nut 33 against the clamp 31, the main frame 2 is fixed on the ladder 11, realizing quick installation.
[0036] Two anti-slip blocks 22 are also fixed on one side wall of the main frame 2 near the ladder 11. The cross-section of the anti-slip blocks 22 is triangular. The two anti-slip blocks 22 are spaced apart and are opposite to the position of the clamp 31. When the clamp 31 is pressed against the ladder 11, the anti-slip blocks 22 are pressed against the two sides of the ladder 11, which further improves the stability of the fixation.
[0037] The length of the main frame 2 is not shorter than the outer diameter of the steel pipe tower 1, and the length direction of the main frame 2 is perpendicular to the length direction of the ladder 11. On the side of the main frame 2 closest to the steel pipe tower 1, there are two opposing protective plates 23. The protective plates 23 have inclined surfaces parallel to the side wall of the steel pipe tower 1, and barbed wire is laid on the protective plates 23 to further improve the anti-climbing effect.
[0038] The protective mechanism 4 includes two supports 41 located at both ends of the main frame 2. One end of the support 41 is fixed vertically to the main frame 2 and extends horizontally away from the steel pipe tower 1. The ends of the two supports 41 away from the main frame 2 are bent towards each other and maintain a certain distance.
[0039] Reference Figure 4 and Figure 5 A rotating shaft 42 is installed between the bracket 41 and the main frame 2. The two rotating shafts 42 are parallel to each other and horizontally arranged between the main frame 2 and the bracket 41. The main frame 2 has a limiting groove 24 for inserting one end of the rotating shaft 42. The bracket 41 has an installation groove 411 for inserting the other end of the rotating shaft 42 at the end away from the main frame 2. The cross-section of the installation groove 411 and the limiting groove 24 are both circular, so that the rotating shaft 42 can rotate within the installation groove 411 and the limiting groove 24 and will not detach from the bracket 41 and the main frame 2 in the vertical direction.
[0040] Each rotating shaft 42 is fixed with a movable window 43. The rotating shaft 42 is fixed in the middle of the movable window 43, so that the movable window 43 can rotate around the rotating shaft 42. When the two movable windows 43 are in a horizontal state, a locking component 44 is provided on the side of the two movable windows 43 that are close to each other. The locking component 44 fixes the position of the two movable windows 43, thereby blocking the climbing path of the ladder 11 and playing a role in preventing climbing.
[0041] Reference Figure 3 and Figure 6 The locking assembly 44 includes hanging rings 441 fixed to the adjacent side walls of the two movable windows 43. A lock head 442 is installed between the hanging rings 441 of the two movable windows 43. The lock head 442 can lock the two hanging rings 441, preventing the movable windows 43 from rotating. When maintenance is required, maintenance personnel can open the lock head 442 with a key and rotate the movable windows 43 to a vertical position, thus facilitating maintenance personnel to continue climbing up the ladder 11 for maintenance. Barbed wire is also laid on the movable windows 43 to further improve the anti-climbing effect.
[0042] The implementation principle of the anti-climbing device for a steel pipe tower in this application embodiment is as follows:
[0043] When installing the climbing device on the ladder 11, after adjusting the main frame 2 to a suitable height using hoisting equipment, the clamp 31 is installed on the side of the ladder 11 closest to the steel pipe tower 1, and then quickly fixed with connecting bolts 32 and nuts 33, so that the main frame 2 is horizontally fixed on the ladder 11. When maintenance work is required, maintenance personnel can open the lock 442 with a key, rotate the movable window 43 to a vertical position, and form an area for continued climbing, thereby enabling maintenance. After maintenance is completed, the movable window 43 rotates to a horizontal position, blocking the climbing path of the ladder 11, thus achieving the effect of preventing climbing.
[0044] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
