Description

Technical Field

[0001] The invention relates to the technical field of high-speed railway track accessories, in particular to an anti-electric corrosion contact network positioner. Background Art

[0002] The electrified overhead contact network equipment of the main bridge of Nanjing Yangtze River Bridge is suspended with a soft cross-fixation. Due to the limitations of conditions such as the conductor height, the design adopts a method of directly connecting the positioning ring wire clamp and the positioner. During the inspection and maintenance of relevant overhead contact network equipment of Nanjing Yangtze River Bridge, it was found that many positioning ring wire clamps, fixed anchor bolts, and positioner hooks showed signs of electrical corrosion. After multiple replacements, this phenomenon occurred repeatedly.

[0003] Analysis showed that the cause was that there was poor contact between the positioning hook and the positioning ring clamp, with air as the dielectric, forming a periodically changing magnetic field in the gap where they had not yet contacted. Since the positioning tube and wrist arm support device connected to the positioning ring clamp were both metal conductors, there were a large number of free electrons inside them. Under the action of alternating voltage, a micro-capacitance was formed in the gap between the positioning ring clamp and the hook, which led to the occurrence of electrical corrosion.

[0016] Furthermore, the tension detection mechanism also includes a turntable, which is connected to the end of the storage roller, and a torsion spring is connected between the turntable and the rotating seat, and the torsion spring provides rotation resistance when the storage roller releases the detection rope.

[0033] like Figure 1-Figure 5 As shown, an anti-electro-corrosion contact network positioner includes a positioner mechanism 100, a static elimination mechanism 200 and a tension detection mechanism 300. The positioner mechanism 100 includes a positioning tube 110 and a positioning ring clamp 140. The positioning ring clamp 140 is connected to the oblique wrist arm. The end of the positioning tube 110 is connected with a hook 130, and the hook 130 is hung on the positioning ring clamp 140; the static elimination mechanism 200 includes an equipotential connecting wire 210, and the equipotential connecting wire 210 is electrically connected to the positioning tube 110 and the positioning ring clamp 140, so as to eliminate the capacitive current at the gap between the positioning ring clamp 140 and the hook 130; the tension detection mechanism 300 is used to detect the tension of the equipotential connecting wire 210, and, when the tension of the equipotential connecting wire 210 increases, decompose the tightening force at both ends of the equipotential connecting wire 210.

[0034] The working mechanism of the contact network locator provided in this embodiment is as follows:

[0035] When in use, the positioning tube 110 of the positioner mechanism 100 is installed on the oblique wrist arm through the positioning ring clamp 140, the end of the positioning tube 110 is connected to the positioning ring clamp 140 through the hook 130, and the equipotential connecting wire 210 is connected between the positioning tube 110 and the positioning ring clamp 140, so that the micro-capacitor formed between the positioning ring clamp 140 and the hook 130 is short-circuited, thereby eliminating the capacitive current in the gap between the positioning ring clamp 140 and the hook 130, avoiding the occurrence of electrical corrosion, and the tension detection mechanism 300 monitors the tension of the equipotential connecting wire 210 in real time, so that when the tension of the equipotential connecting wire 210 increases due to factors such as wind, the tension of the equipotential connecting wire 210 is promptly decomposed, thereby ensuring the connection stability of the equipotential connecting wire 210 and avoiding its detachment.

[0036] Among the optional methods of this embodiment, the more preferred ones are:

[0037] The positioner mechanism 100 further includes a positioning wire clamp 120 , which is fixedly connected to the positioning tube 110 and clamped to the contact network.

[0038] The end of the positioning tube 110 is fixedly connected to the positioning wire clamp 120, and the positioning wire clamp 120 is clamped on the contact network to provide positioning for the contact network.

[0039] Among the optional methods of this embodiment, the more preferred ones are:

[0040] The static elimination mechanism 200 further includes a fixed wire clamp 230 , which is connected to the oblique arm, electrically connected to the equipotential connection wire 210 , and electrically connected to the positioning ring wire clamp 140 .

[0041] The fixed wire clamp 230 is connected to the oblique wrist arm through a clamp or the like, and the equipotential connecting wire 210 is connected to the fixed wire clamp 230 through a nut or welding to ensure conductivity. The fixed wire clamp 230 is electrically connected to the positioning ring wire clamp 140, so that the current forms a closed loop, thereby ensuring the elimination of the micro-capacitance formed between the hook 130 and the positioning ring wire clamp 140.

[0042] Among the optional methods of this embodiment, the more preferred ones are:

[0043] The static elimination mechanism 200 further includes a fixing clamp 220 . The fixing clamp 220 is connected to the positioning tube 110 , and the equipotential connection line 210 is electrically connected to the fixing clamp 220 .

[0044] The fixing clamp 220 is connected to the positioning tube 110 and is conductive, and the equipotential connection line 210 is connected to the fixing clamp 220, so that a common positioner can be easily modified, thereby preventing electrical corrosion from occurring.

[0045] Among the optional methods of this embodiment, the more preferred ones are:

[0046] The static elimination mechanism 200 also includes a protective tube 240, which is composed of a plurality of annular tubes 241 and a plurality of flexible tubes 242 connected at intervals. The two annular tubes 241 located at the ends are respectively connected with a first pull rope 243 and a second pull rope 244. The first pull rope 243 and the second pull rope 244 are respectively passed through all the annular tubes 241 other than those fixedly connected thereto; the first pull rope 243 and the second pull rope 244 are respectively fixedly connected to a fixed clamp 220 and a fixed wire clamp 230 at one end away from the annular tube 241 connected thereto. When the tension detection mechanism 300 detects that the tension of the equipotential connecting line 210 increases, the first pull rope 243 and the second pull rope 244 are both tightened to shorten the protective tube 240, thereby reducing the tension of the equipotential connecting line 210.

[0047] When blown by strong wind, the equipotential connecting line 210 will be tightened so that the connection parts at both ends are subjected to greater tension. In order to prevent the equipotential connecting line 210 from being blown off, when the tension detection mechanism 300 detects that the tension of the equipotential connecting line 210 increases, the first pull rope 243 and the second pull rope 244 are tightened, so that the annular tubes 241 at both ends are moved closer to the middle, so that the flexible tube 242 is deformed, so that the overall length of the protective tube 240 is reduced to less than the length of the equipotential connecting line 210, thereby ensuring that the tension at the end of the equipotential connecting line 210 is reduced. Figure 5 , is a force model diagram of the equipotential connecting line 210, in which point A and point D are fixed connection points at both ends of the equipotential connecting line 210, and point B and point C are connection points at both ends of the protective tube 240. When the wind force increases, the shortening of the protective tube 240 makes most of the wind force borne by point B and point C, thereby preventing the equipotential connecting line 210 from falling off.

[0048] Among the optional methods of this embodiment, the more preferred ones are:

[0049] The static elimination mechanism 200 also includes a sliding ring 221 and a slider 250. The sliding ring 221 is slidably connected to the fixed clamp 220. The slider 250 slides on the fixed wire clamp 230. The first pull rope 243 is connected to the slider 250. The second pull rope 244 is connected to the sliding ring 221. When the slider 250 slides, the first pull rope 243 and the second pull rope 244 can be tightened or released.

[0050] The sliding ring 221 and the slider 250 are both configured to be slidably connected, so that the first pull rope 243 and the second pull rope 244 can be pulled away from each other by the sliding ring 221 and the slider 250. When the sliding ring 221 and the slider 250 move away from each other, the first pull rope 243 and the second pull rope 244 are both pulled, and the protective tube 240 can be shortened at this time. The sliding ring 221 can be fixed to the fixed clamp 220 by a nut, and only the slider 250 slides, and the first pull rope 243 and the second pull rope 244 can also be tightened. By adjusting the position of the sliding ring 221 and fixing it, the initial length of the protective tube 240 is limited.

[0051] Among the optional methods of this embodiment, the more preferred ones are:

[0052] The tension detection mechanism 300 includes a swivel seat 310, which is connected to the positioning ring clamp 140. A storage roller 320 is rotatably connected to the positioning ring clamp 140. A detection rope 330 is wound around the storage roller 320, and the detection rope 330 is connected to the protective tube 240. The end of the storage roller 320 is connected to an angle sensor 340. When the equipotential connecting line 210 is in a relaxed state, the storage roller 320 stores the detection rope 330. When the equipotential connecting line 210 is in a taut state, the storage roller 320 releases the detection rope 330 to rotate the storage roller 320, so that the angle sensor 340 obtains the rotation angle information of the storage roller 320 and feeds back the tension information.

[0053] The end of the detection rope 330 is connected to the protective tube 240. When the equipotential connecting line 210 is swung by the wind, the protective tube 240 swings synchronously. At this time, the swing of the protective tube 240 pulls the detection rope 330, so that the detection rope 330 is released from the storage roller 320. At this time, the storage roller 320 rotates, and then the angle sensor 340 at the end of the storage roller 320 collects the rotation angle signal of the storage roller 320. Since the release of the detection rope 330 has resistance, the rotation of the storage roller 320 also has resistance. The corresponding relationship between the rotation angle of the storage roller 320 and the rotation resistance of the storage roller 320 is measured in advance. Therefore, during use, the data detected by the angle sensor 340 can be used to obtain the tension of the equipotential connecting line 210, and then the data detected by the angle sensor 340 is sent through wireless transmission, so that the staff can understand the status of the equipotential connecting line 210 in time.

[0054] Among the optional methods of this embodiment, the more preferred ones are:

[0055] The tension detection mechanism 300 further includes a turntable 350 , which is connected to the end of the storage roller 320 , and a torsion spring is connected between the turntable 350 and the rotating seat 310 , which provides rotation resistance when the storage roller 320 releases the detection rope 330 .

[0056] The torsion spring is set to provide resistance to the rotation of the storage roller 320, thereby making the release of the detection rope 330 have resistance. The detection rope 330 can not only feedback the tension signal to the angle sensor 340, but also provide traction to the equipotential connecting line 210, so that the equipotential connecting line 210 is further reinforced when blown by strong wind.

[0057] Among the optional methods of this embodiment, the more preferred ones are:

[0058] A push block 370 is slidably connected to the fixed wire clamp 230, and a connecting rod 360 is arranged between the push block 370 and the turntable 350. The two ends of the connecting rod 360 are respectively hinged to the turntable 350 and the push block 370 through a spherical hinge seat. The hinge between the connecting rod 360 and the push block 370 deviates from the center of the turntable 350. When the turntable 350 rotates, the push block 370 is pushed and pulled by the connecting rod 360, so that the push block 370 pushes the slider 250 to slide.

[0059] When the storage roller 320 rotates, the turntable 350 rotates synchronously. At this time, the turntable 350 drives the connecting rod 360 to move from an inclined state to a horizontal state, so that the connecting rod 360 pushes the push block 370, and the push rod 371 connected to the push block 370 pushes the slider 250, so that the slider 250 moves away from the sliding ring 221, thereby shortening the protective tube 240 to decompose the tension of the equipotential connecting line 210.

[0060] Among the optional methods of this embodiment, the more preferred ones are:

[0061] A telescopic rod 380 is swingably connected to the fixed wire clamp 230, the end of which is hinged to the slider 250. A spring 381 is sleeved on the telescopic rod 380, and both ends of the spring 381 are respectively connected to the two ends of the telescopic rod 380. When the slider 250 is at both ends of its sliding stroke, the telescopic rod 380 is in an extended state.

[0062] The cooperation of the telescopic rod 380 and the spring 381 enables the slider 250 to have the force to maintain it at both ends of the sliding stroke, so that the protective tube 240 has only two states, extended and shortened, and also ensures that the protective tube 240 stably protects the equipotential connecting line 210. The push rod 371 can be fixedly connected to the slider 250, or it can be connected by magnetic attraction or a connection method equivalent to magnetic attraction effect, so that the push rod 371 can push the slider 250 away, and when the connecting rod 360 swings from a horizontal to an inclined state, it can also pull the slider 250 back to its original position. A counterweight block 361 is also provided at the end of the connecting rod 360 close to the turntable 350, so that the connecting rod 360 has a tendency to move to the inclined state under the gravity of the counterweight block 361, so that the storage roller 320 is more likely to rotate in the opposite direction, so that each component can be reset.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
