Description

Technical Field

[0001] This invention relates to the field of power angle steel tower reinforcement technology, specifically to a temporary repair and reinforcement device for damaged narrow-base power angle steel towers. Background Art

[0002] Power line angle steel towers are constructed from power line angle steel. During production, the perpendicularity of the two sides of the angle steel changes due to compression after forming. Before use, the angle steel needs to be inspected and repaired. However, the following problems arise during the inspection and repair process: 1. Traditional angle steel inspection methods involve manual inspection using tools such as right-angle gauges or levels. While simple and convenient, this method can only detect severely deformed areas, failing to effectively detect minor deformations. 2. Traditional angle steel inspection processes do not include repair, making it difficult to promptly repair the inspected angle steel.

[0003] Chinese patent CN112090995B discloses a power transmission tower angle steel inspection and repair device, including an L-shaped workbench, an inspection mechanism, and a repair mechanism. The L-shaped workbench is installed on an existing working surface. The inspection mechanism is installed on the upper surface of the L-shaped workbench, and the repair mechanism is installed on the front surface of the inspection mechanism. The inspection mechanism includes a first electric slider, a first L-shaped connecting plate, a second L-shaped connecting plate, a measuring group, a second electric slider, a first round shaft, a horizontal inspection roller, a second round shaft, a connecting ball, a vertical inspection roller, a third round shaft, and a fourth round shaft. A first rectangular groove is formed on the upper surface of the vertical section of the L-shaped workbench. A first electric slider is installed in the first rectangular groove. A first L-shaped connecting plate is installed on the upper surface of the first electric slider. A second L-shaped connecting plate is installed on the right end surface of the first L-shaped connecting plate. The first and second L-shaped connecting plates are connected together. The upper part is equipped with a measuring group. A second electric slider is installed on the lower end face of the second L-shaped connecting plate. The second electric slider is connected to the second rectangular groove via a sliding fit. The second rectangular groove is located on the upper end face of the horizontal section of the L-shaped worktable. A first rectangular slot is located on the left end face of the vertical section of the second L-shaped connecting plate. The first rectangular slot is connected to the first round shaft via a sliding fit. A horizontal detection roller is installed on the left end face of the first round shaft. A second round shaft is installed on the left end face of the horizontal detection roller. The second round shaft is connected to the first circular arc groove via a sliding fit. An arc groove is formed on the right end face of the connecting ball. The connecting ball is hollow inside. A second arc groove is formed on the upper end face of the connecting ball. The second arc groove is connected to the third circular shaft via a sliding fit. A vertical detection roller is installed on the upper end face of the third circular shaft, and a fourth circular shaft is installed on the upper end face of the vertical detection roller. The fourth circular shaft is connected to the second rectangular groove via a sliding fit. The second rectangular groove is formed on the lower end face of the horizontal section of the first L-shaped connecting plate. After the angle steel is placed on the L-shaped worktable, the first and second electric sliders move simultaneously. The movable slider and the second electric slider drive the first and second L-shaped connecting plates to move backward. The first and second L-shaped connecting plates synchronously drive the horizontal and vertical detection rollers to move backward to inspect the angle steel. When the horizontal or vertical section of the angle steel is bent, the horizontal and vertical detection rollers will move to the right or upward due to the bending of the angle steel. The measurement group installed on the first and second L-shaped connecting plates will show the detection situation and transmit the measurement situation to the repair mechanism for corresponding repair.

[0004] While the above solutions can repair the deformed parts of the angle steel, this is only applicable during production. In real life, power angle steel towers are installed outdoors, and some are even located by the roadside. It is inevitable that vehicles will collide with the power angle steel towers. The base of the power angle steel tower is usually supported by four corners. When a vehicle hits the power angle steel tower, it will inevitably damage the support legs of the power angle steel tower, causing the power angle steel tower to tilt or even collapse. This will cause injury to the vehicle driver and will also make subsequent construction and maintenance difficult. Summary of the Invention

[0005] To address the aforementioned problems, a temporary repair and reinforcement device for damaged narrow-base angle steel towers is provided. When a vehicle impacts the support leg, a triggering device located on one side of the support leg is activated. This triggering device causes a sliding block to slide along the length of the support leg. A guiding device guides the sliding block, and a reinforcement rod hinged to the sliding block slides down synchronously with it. When the bottom of the reinforcement rod contacts the bottom of the groove in the base, an offset device located on the reinforcement rod is activated. This offset device causes the reinforcement rod to shift towards the support leg. Due to the damage to the support leg, the center of gravity of the power angle steel tower shifts towards the damaged support leg. When one leg shifts, the power angle steel tower will tilt towards the damaged leg. The tilting force will react through the reinforcing rod onto the sliding block. The sliding block will then transfer the reaction force to the load via a connecting rod. The one-way device on the upper part of the load will prevent the load from sliding upwards, thus achieving self-locking of the power angle steel tower. This ensures that the center of gravity of the power angle steel tower will not shift after the leg is impacted. Furthermore, the reinforcing rod is initially located in the upper part of the leg, so it will not be affected when the leg is impacted, ensuring the support of the reinforcing rod and preventing the power angle steel tower from collapsing after being impacted.

[0006] To address the existing technical problems, a temporary repair and reinforcement device for damaged narrow-base angle steel towers in power grids is provided, comprising a support leg, a connecting device, and a base.

[0011] Preferably, the locking device includes a locking groove and a locking block; the locking groove is vertically formed on the upper part of the sliding block and is located on one side of the reinforcing rod; the locking block is fixedly set on the upper part of the trigger rod and engages with the locking groove.

[0012] Preferably, the guiding device includes a guide rail and a slide groove; the guide rail is fixedly mounted on the support leg along the length direction of the support leg; the slide groove is formed on the side wall of the sliding block, and the sliding block slides with the guide rail through the slide groove.

[0013] Preferably, the one-way device includes a drop bar, a limiting groove, a limiting member, a fixed base, a sliding rod, a spring, and an anti-rotation component; the drop bar is vertically fixedly installed on the upper part of the weight, and a mounting plate is horizontally fixedly installed on the top of the support leg, with the drop bar passing through the mounting plate and slidingly engaging with it; multiple limiting grooves are provided, evenly arranged along the length of the drop bar; the limiting member is located on one side of the drop bar, can slide horizontally, engages with the limiting groove, and has a chamfer on the upper side of the limiting member near the limiting groove; the fixed base is located on one side of the limiting member; the sliding rod is fixedly installed along the length of the limiting member on the side of the limiting member near the fixed base, passes through the fixed base, and slides with it; there is a gap between the fixed base and the limiting member, and the spring is located within the gap along the axis of the sliding rod; the anti-rotation component is located on one side of the limiting member, and is used to prevent the limiting member from rotating along the axis of the sliding rod.

[0015] Preferably, sand is placed in the groove of the base.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention utilizes a weight, connecting rod, one-way device, reinforcing rod, triggering device, sliding block, guiding device, and offsetting device. When a vehicle impacts the outrigger, the triggering device on one side of the outrigger is activated, causing the sliding block to slide along the length of the outrigger. The guiding device guides the sliding block, and the reinforcing rod hinged to the sliding block slides down synchronously with the sliding block. When the bottom of the reinforcing rod contacts the bottom of the groove in the base, the offsetting device on the reinforcing rod is activated. The offsetting device causes the reinforcing rod to shift towards the outrigger. Due to the damage to the outrigger, the center of gravity of the power angle steel tower shifts. The tower will shift towards the damaged leg, causing it to tilt. This tilting force will then react through the reinforcing rod onto the sliding block. The sliding block, via a connecting rod, will transfer the reaction force to the load. A one-way device on the top of the load will prevent it from sliding upwards, thus achieving self-locking of the power angle steel tower. This ensures that the center of gravity of the tower will not shift after an impact. Furthermore, the reinforcing rod is initially located in the upper part of the leg, so it will not be affected when the leg is impacted, ensuring the support of the reinforcing rod and preventing the power angle steel tower from collapsing after an impact.

Detailed Implementation

[0030] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1 and Figure 2 A temporary repair and reinforcement device for damaged narrow-base angle steel towers of power plants includes a support leg 1, a connecting device 2, and a base 3. The connecting device 2 includes a weight 21, a connecting rod 211, a one-way device 22, a reinforcing rod 23, a triggering device 24, a sliding block 25, a guiding device 26, and an offset device 27. The weight 21 is positioned directly above the center of the base 3, and a groove is provided in the center of the base 3, allowing the weight 21 to descend vertically. The one-way device 22 is positioned above the weight 21, moving synchronously with the weight 21 and restricting its ascent. The support leg 1 is inclinedly positioned on the base 3, and the guiding device 26 is positioned on the support leg 1 along its length. The sliding block 25 is slidably positioned along the length of the support leg 1. On the guide device 26, the two ends of the connecting rod 211 are respectively hinged to the sliding block 25 and the weight 21. When the weight 21 falls, it drives the sliding block 25 to slide through the connecting rod 211. The reinforcing rod 23 is vertically set on the sliding block 25, and the end of the reinforcing rod 23 near the sliding block 25 is hinged to the sliding block 25. The triggering device 24 is set on the side of the support leg 1 near the base 3. The triggering device 24 is activated after the support leg 1 is damaged by external force. After the triggering device 24 is activated, it can make the sliding block 25 slide along the length direction of the support leg 1. The offsetting device 27 is set on the reinforcing rod 23. The offsetting device 27 is triggered after the bottom of the reinforcing rod 23 contacts the ground and drives the reinforcing rod 23 to tilt towards the support leg 1. The bottom of the reinforcing rod 23 abuts against the inner wall of the groove.

[0032] Four support legs 1 are evenly distributed around the center of the base 3. When one of the four support legs 1 is impacted, the stability of the power angle steel tower is compromised, causing the center of gravity of the power angle steel tower to shift. This can easily lead to the power angle steel tower tilting or collapsing. When a vehicle hits a support leg 1, a triggering device 24 located on one side of the support leg 1 is activated. After activation, the triggering device 24 causes the sliding block 25 to slide along the length of the support leg 1. The guide device 26 guides the sliding block 25, and the reinforcing rod 23 hinged to the sliding block 25 slides down synchronously with the sliding block 25. When the bottom of the reinforcing rod 23 contacts the bottom of the groove in the base 3, the offset device 27 located on the reinforcing rod 23 is activated. The offset device 27 causes the reinforcing rod 23 to shift towards the support leg 1. Because the support leg 1 is damaged, the center of gravity of the power angle steel tower will shift towards the damaged support leg 1. When leg 1 shifts to one side, the power angle steel tower will tilt towards the damaged leg 1. The tilting force will react on the sliding block 25 through the reinforcing rod 23. The sliding block 25 transmits the reaction force to the weight 21 through the connecting rod 211. The one-way device 22 on the upper part of the weight 21 will prevent the weight 21 from sliding upward, thus achieving self-locking of the power angle steel tower. This ensures that the center of gravity of the power angle steel tower will not shift after the leg 1 is impacted. The reinforcing rod 23 is initially located in the upper part of the leg 1, and will not be affected when the leg 1 is impacted. That is, before the vehicle impacts the leg 1, the reinforcing rod 23 is in the highest position. Only after the leg 1 is impacted will the triggering device 24 be triggered. At this time, the reinforcing rod 23 will descend under the action of the weight 21, ensuring the support of the reinforcing rod 23 and preventing the power angle steel tower from collapsing after the impact.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The triggering device 24 includes a trigger tube 241 and a bellows tube 242. The trigger tube 241 is disposed on one side of the support leg 1 along the length direction of the support leg 1. The bellows tube 242 is disposed above the trigger tube 241 and is disposed on one side of the support leg 1 along the length direction of the support leg 1. The upper part of the bellows tube 242 is fixedly connected to the lower part of the sliding block 25, and the lower part of the bellows tube 242 is connected to the upper part of the trigger tube 241. Both the trigger tube 241 and the bellows tube 242 are filled with water.

[0034] When the support leg 1 is not impacted, the trigger tube 241 will not be damaged, so the water in the trigger tube 241 and the bellows 242 will not flow out, and the trigger tube 241 and the bellows 242 will be in a fully sealed state. Under the action of water pressure, the sliding block 25 set on the bellows 242 will not be able to descend. However, after the support leg 1 is impacted, the trigger tube 241 located on one side of the support leg 1 will be damaged, so the water in the trigger tube 241 will leak out, and the water in the bellows 242 connected to the trigger tube 241 will also flow out from the damaged part of the trigger tube 241. The water pressure in the bellows 242 can no longer support the weight 21 acting on the sliding block 25, so the sliding block 25 will descend, and finally the reinforcing rod 23 in the middle will contact the bottom of the groove of the base 3.

[0035] Reference Figure 4 The triggering device 24 also includes a connecting pipe 243; the connecting pipe 243 has a ring structure, the upper part of the connecting pipe 243 is connected to the lower part of the bellows 242, and the lower part of the connecting pipe 243 is connected to the upper part of the triggering pipe 241.

[0036] Since there are four support legs 1, if the corrugated pipe 242 and trigger pipe 241 corresponding to each support leg 1 are not connected, water will leak out of the trigger pipe 241 on the side that is hit, while the other three sets of corrugated pipes 242 and trigger pipes 241 will remain sealed. This will prevent the sliding blocks 25 corresponding to the three sets of corrugated pipes 242 and trigger pipes 241 that have not leaked water from from descending. The weight of the weight 21 will be evenly distributed on the four sliding blocks 25. Only when all the water leaks out can the sliding blocks 25 descend. After the connecting pipe 243 is installed, it can be ensured that if one of the trigger pipes 241 is damaged, the water in all the corrugated pipes 242 can flow out through the connecting pipe 243 from the damaged trigger pipe 241, ensuring that the sliding blocks 25 can descend normally.

[0037] Reference Figure 3 and Figure 4 Trigger tube 241 is made of brittle material.

[0038] By making the trigger tube 241 a brittle material, it can be ensured that the trigger tube 241 located on one side of the support leg 1 is more likely to break when the support leg 1 is impacted by an external force. This avoids the situation where the trigger tube 241 does not break after the support leg 1 is deformed by impact, thus preventing the weight 21 from driving the reinforcing rod 23 to descend.

[0039] Reference Figure 2 and Figures 5-7The offset device 27 includes a spring box 271, a rotating groove 272, a locking device 273, and a trigger rod 274. The rotating groove 272 is vertically opened through the sliding block 25, and the upper part of the reinforcing rod 23 is hinged in the rotating groove 272. The spring box 271 is set on the side wall of the sliding block 25 and is connected to the reinforcing rod 23. The spring box 271 can drive the reinforcing rod 23 to rotate, and the spring in the spring box 271 is in a coiled state. The reinforcing rod 23 has a through groove that runs through its length direction, and the trigger rod 274 is slidably set in the through groove along the length direction of the reinforcing rod 23. The locking device 273 is set on the upper part of the trigger rod 274 and is used to restrict the rotation of the reinforcing rod 23.

[0040] When the support leg 1 is not impacted, the locking device 273 is locked. At this time, the bottom of the trigger rod 274 extends from the bottom of the reinforcing rod 23. When the support leg 1 is impacted, the sliding block 25 descends under the action of the weight 21. At this time, the reinforcing rod 23 is still in a vertical state and descends synchronously with the sliding rod 224. When the bottom of the reinforcing rod 23 contacts the bottom of the groove of the base 3, the trigger rod 274 will be lifted up. The trigger rod 274 unlocks the locking device 273. Since the spring in the spring box 271 is in a coiled state, the reinforcing rod 23 can rotate freely after the locking device 273 is unlocked. The spring box 271 drives the reinforcing rod 23 to rotate, causing the reinforcing rod 23 to shift towards the support leg 1. In this way, the reinforcing rod 23 can more stably support the power angle steel tower after contacting the bottom of the groove.

[0041] Reference Figure 6 , Figure 7 and Figure 9 The locking device 273 includes a locking groove 2731 and a locking block 2732; the locking groove 2731 is vertically opened on the upper part of the sliding block 25 and is located on one side of the reinforcing rod 23; the locking block 2732 is fixedly installed on the upper part of the trigger rod 274 and engages with the locking groove 2731.

[0042] When the reinforcing rod 23 descends and contacts the bottom of the groove in the base 3, the trigger rod 274 set in the reinforcing rod 23 is lifted up, and the locking block 2732 set on the top of the trigger rod 274 will slide out from the locking groove 2731 under the action of the trigger rod 274. In this way, the locking groove 2731 and the locking block 2732 will disengage, and then the coil spring box 271 can drive the reinforcing rod 23 to rotate.

[0043] Reference Figure 3 , Figure 7 and Figure 9The guide device 26 includes a guide rail 261 and a slide groove 262. The guide rail 261 is fixedly mounted on the support leg 1 along the length direction of the support leg 1. The slide groove 262 is formed on the side wall of the sliding block 25, and the sliding block 25 slides with the guide rail 261 through the slide groove 262.

[0044] When the support leg 1 is impacted, the sliding block 25 will slide along the length of the guide rail 261. Under the guidance of the guide rail 261, the four sliding blocks 25 gradually open, so that the reinforcing rod 23 set on the sliding block 25 can more stably support the power angle steel tower. When the weight 21 descends, the sliding block 25 is driven by the connecting rod 211 to gradually unfold as it descends. When it is in the retracted state, the height advantage of the power angle steel tower can be used to store the sliding block 25. When it is unfolded, the sliding block 25 can be smoothly unfolded under the guidance of the guide rail 261, which improves the stability of the reinforcing rod 23 in supporting the power angle steel tower.

[0045] Reference Figure 1 , Figure 5 , Figure 8 and Figure 10 The one-way device 22 includes a drop bar 221, a limiting groove 2211, a limiting member 222, a fixed base 223, a sliding rod 224, a spring 225, and an anti-rotation component 226. The drop bar 221 is vertically fixed on the upper part of the weight 21, and a mounting plate is horizontally fixed on the top of the support leg 1. The drop bar 221 passes through the mounting plate and slides with it. Multiple limiting grooves 2211 are provided and are evenly arranged along the length of the drop bar 221. The limiting member 222 is provided on one side of the drop bar 221 and can slide horizontally. The limiting member 222 engages with the limiting groove 2211. In this configuration, the upper side of the limiting member 222 near the limiting groove 2211 is chamfered; the fixed seat 223 is disposed on one side of the limiting member 222; the sliding rod 224 is fixedly disposed along the length of the limiting member 222 on the side of the limiting member 222 near the fixed seat 223, the sliding rod 224 passes through the fixed seat 223 and slides with the fixed seat 223; there is a gap between the fixed seat 223 and the limiting member 222, and the spring 225 is disposed in the gap along the axis of the sliding rod 224; the anti-rotation component 226 is disposed on one side of the limiting member 222, and the anti-rotation component 226 is used to prevent the limiting member 222 from rotating along the axis of the sliding rod 224.

[0046] When the weight 21 descends, it causes the drop bar 221 to fall synchronously. The limiting groove 2211 on the drop bar 221 continuously engages with the limiting component 222. When the reinforcing rod 23 contacts the inner wall of the groove in the base 3, the drop bar 221 stops falling. At the same time, the limiting groove 2211 engages with the limiting block. The tilting force of the power angle steel tower will act in the opposite direction on the reinforcing rod 23. At this time, the limiting component 222 locks the limiting groove 2211, preventing the drop bar 221 from rising. This achieves the self-locking of the reinforcing rod 23.

[0047] Reference Figure 8 and Figure 10 The anti-rotation component 226 includes an anti-rotation rod 2261 and an anti-rotation groove 2262. The anti-rotation rod 2261 is horizontally fixed on the side wall of the fixed base 223, and the anti-rotation rod 2261 corresponds one-to-one with the limiting member 222. The anti-rotation groove 2262 is horizontally opened on the side wall of the limiting member 222, and the anti-rotation rod 2261 and the anti-rotation groove 2262 are slidably engaged.

[0048] Because the anti-rotation rod 2261 and the anti-rotation groove 2262 slide together, when the spring 225 drives the limiting member 222 to slide, the limiting member 222 can only slide in the horizontal direction and cannot rotate along the axis of the sliding rod 224, thus ensuring that the limiting member 222 can be accurately engaged in the limiting groove 2211.

[0049] Reference Figure 1 and Figure 2 Sand is placed in the groove of base 3.

[0050] By placing sand in the groove of the base 3, the deflection device can more easily drive the reinforcing rod 23 to deflect after it comes into contact with the bottom of the groove. As the reinforcing rod 23 is continuously inserted into the sand under the action of the weight 21 and its own inertia, the stability of the reinforcing rod 23 during support can be enhanced.

[0051] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but 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 all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
