Description

Technical Field

[0001] This utility model relates to the technical field of shorting tools for tension insulators, and in particular to a quick-connecting shorting tool for construction shorting tension insulators. Background Technology

[0002] In the construction and maintenance of transmission lines, short-circuiting tension insulators is an important and necessary operation. It can prevent injuries from induced electric shock and plays a key role in ensuring the safety of construction personnel and the normal operation of the line. In practical applications, the operation of short-circuiting tension insulators usually requires the following techniques and tools:

[0003] 1. Conductive connection components, such as metal wires and conductive clamps, are used to achieve electrical short circuits between tension insulators;

[0004] 2. Fixing devices, such as screws, nuts, and clamps, to ensure a secure connection between the conductive connection components and the tension insulator;

[0005] 3. The insulated operating rod allows construction personnel to perform short-circuit operations from a safe distance.

[0006] Existing Chinese patent: A tension insulator string short-circuiting device, patent number: CN220325118U. This device includes: a colored flexible strip conductor; clamps connected to both ends of the colored flexible strip conductor, the clamps having a cross-hinged structure, one side of the hinge being a clamping part and the other side a handle part, the handle part having a ratchet and an unlocking trigger on its inner side, the ratchet being fixedly connected to one side of the handle, the unlocking trigger being rotatably connected to the other side of the handle, an electromagnetic unlocking component being fixedly connected to the side of the handle near the unlocking trigger; a GPS positioning component installed on the clamp handle; and an identification component installed on the clamp handle. The advantages of this invention compared to existing technologies are: it enables quick assembly and disassembly before and after stringing on tension towers in power line projects, preventing omissions or oversights in the string short-circuiting connection, greatly reducing the risk of omissions, and avoiding electric shock injuries and violations of operating procedures.

[0007] However, during the implementation of the above technical solution, at least the following technical problems were found: The above short-circuiting device connects the hardware at both ends of the insulator through clamps at both ends. During use, the handles need to be manually gripped to close the clamps. Since the tension insulator is arranged laterally, the end away from the tension tower is in a suspended state. When using it, the operator needs to lean out or climb out along the insulator to clamp the clamps onto the metal of the insulator. This not only results in a slow short-circuiting speed but is also quite dangerous. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a quick-connection shorting tool for tension insulators used in construction. This solves the problems of the aforementioned shorting devices, which connect the metal fittings at both ends of the insulator using clamps at both ends. During use, the clamps need to be manually gripped to close. Since tension insulators are arranged laterally, the end furthest from the tension tower is suspended in the air. Operators need to lean out or climb along the insulator to clamp the clamps onto the metal of the insulator, resulting in slow shorting speeds and a relatively dangerous technical problem.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A quick-connection shorting tool for tension insulators used in construction includes a housing, a conductive component disposed between two housings, a clamping arm for holding hardware slidably mounted inside the housing, a double-sided helical toothed plate slidably mounted inside the housing, a transmission rod for transmitting power installed between the clamping arm and the double-sided helical toothed plate, a locking plate for locking the double-sided helical toothed plate symmetrically slidably mounted inside the housing, sleeves symmetrically fixedly mounted at both ends of the housing, a first gear for resetting the locking plate installed on the side end of the locking plate, an unlocking frame slidably mounted on the housing, a second spring for resetting the unlocking frame installed on the unlocking frame, and a third spring for resetting the double-sided helical toothed plate installed on the side end of the double-sided helical toothed plate.

[0011] Preferably, a conductive rod for connecting conductive components is fixedly installed on the side end of the double-sided helical toothed plate.

[0012] Preferably, the end of the clamping arm is fixedly equipped with a clamping plate for increasing friction.

[0013] Preferably, the conductive component includes a wire, a threaded sleeve, an insulating sleeve, and a luminescent sleeve.

[0014] Preferably, two threaded sleeves are symmetrically rotated and installed at both ends of the wire.

[0015] Preferably, the insulating sleeve is fixedly installed on the outer wall of the conductor; the insulating sleeve is a striking red.

[0016] Preferably, the luminous cover is evenly and fixedly installed on the outer wall of the insulating cover; the luminous cover will emit light after absorbing light.

[0017] Preferably, the two threaded sleeves are threadedly connected to the two conductive rods respectively.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When using the device, insert the insulating rod into the socket. Then, by holding the insulating rod, extend one end of the device towards the hardware at the suspended end of the insulator, so that the two clamping arms are inserted above and below the hardware respectively. During this process, the double-sided inclined toothed plate will be squeezed by the hardware, causing the double-sided inclined toothed plate to slide inward. The inward sliding of the double-sided inclined toothed plate will pull the two clamping arms inward through the transmission rod. The two clamping arms will clamp the hardware from the upper and lower ends. During this process, the two locking plates will lock the double-sided inclined toothed plate from both sides, so that the two clamping arms always keep clamping the hardware. Then, clamp the other end of the device (clamping arm) near the hardware of the tension tower to complete the short circuit. The short circuit operation can be performed by pushing, which achieves the effect of improving the short circuit speed and increasing the safety of the operation.

[0020] 2. Before use, since the lengths of tension insulators of different specifications vary, the conductive component can be removed by rotating the threaded sleeve and replaced with a conductive component of appropriate length. During installation, tighten the threaded sleeve and the conductive rod thread to allow the two double-sided helical tooth plates to be connected by the wire. The outside of the wire is conspicuously red, which can attract the attention of the operators after the work is completed. In addition, the luminous sleeve can light up during nighttime operations to remind the operators, thus achieving the effect of preventing the operators from forgetting to remove this device.

[0029] This application provides a quick-connection shorting tool for tension insulators used in construction, effectively solving the problems of the aforementioned shorting devices. Traditional methods connect the hardware at both ends of the insulator using clamps at both ends. During use, the clamps require manual gripping of the handles to close. Since tension insulators are arranged laterally, the end furthest from the tension tower is suspended. Operators must lean out or climb along the insulator to clamp the clamps onto the metal, resulting in slow shorting speeds and considerable danger. In this new tool, the insulating rod is inserted into the sleeve, and then one end of the device is extended towards the hardware at the suspended end of the insulator by holding the insulating rod. The two clamping arms are inserted above and below the hardware. During this process, the double-sided inclined toothed plate is squeezed by the hardware, causing it to slide inwards. This inward sliding of the double-sided inclined toothed plate pulls the two clamping arms forward via a transmission rod. The device slides inward, and the two clamping arms will clamp the fitting from both the top and bottom. During this process, the two toothed plates will clamp the double-sided inclined toothed plates from both sides, ensuring that the two clamping arms always hold the fitting. Then, the other end of the device (clamping arm) is clamped onto the fitting near the tension tower to complete the short circuit. The short circuit operation can be performed by pushing, which improves the short circuit speed and increases the safety of the operation. Before use, since the length of tension insulators of different specifications varies, the threaded sleeve can be rotated to remove the conductive component and replace it with a conductive component of appropriate length. During installation, the threaded sleeve is tightened with the conductive rod thread, which allows the two double-sided inclined toothed plates to conduct through the wire. The outside of the wire is conspicuously red, which can attract the attention of the operators after the operation is completed. In addition, the luminous sleeve can light up during nighttime operation to remind the operators and prevent them from forgetting to remove the device.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the technical solution in this application embodiment effectively solves the aforementioned short-circuiting device problem. It connects the metal fittings at both ends of the insulator using clamps at both ends. During use, the clamps need to be manually gripped to close. Since the tension insulator is arranged laterally, the end furthest from the tension tower is suspended. Operators need to lean out or climb along the insulator to clamp the clamps onto the metal of the insulator. This not only results in slow short-circuiting speed but is also quite dangerous. The overall approach is as follows:

The luminous sleeve 17 will emit light after absorbing light. The two threaded sleeves 15 are threadedly connected to the two conductive rods 12 respectively.

[0037] Double-sided helical toothed plate 3: made of metal, it slides inward under the pressure of the fittings and pulls the clamping arm 2 through the transmission rod 4, and is also connected to the conductive component;

[0038] Transmission rod 4: made of metal, it transmits power between the double-sided helical toothed plate 3 and the clamping arm 2 to achieve the clamping action;

[0039] Clamping plate 5: It clamps the double-sided inclined plate 3 from both sides, so that the clamping arm 2 keeps the hardware in a clamping state;

[0040] Sleeve 6: Used to insert the insulating rod for easy operation and control of the device;

[0050] Luminous sleeve 17: Evenly and fixedly installed on the outer wall of insulating sleeve 16, it can emit light at night to remind workers and prevent them from forgetting.

[0051] Working principle:

[0052] The first step, during use, is to insert the insulating rod into the insert 6. Then, by holding the insulating rod, one end of the device is extended towards the hardware at the suspended end of the insulator, so that the two clamping arms 2 are inserted into the hardware from above and below. During this process, the double-sided helical toothed plate 3 will be squeezed by the hardware, causing it to slide inward. The inward sliding of the double-sided helical toothed plate 3 will pull the two clamping arms 2 inward through the transmission rod 4. The two clamping arms 2 will clamp the hardware from both above and below. During this process, the two locking plates 5 will lock the double-sided helical toothed plate 3 from both sides, ensuring that the two clamping arms 2 always maintain clamping on the hardware. Then, clamp the other end of the device (clamping arm 2) to the fittings near the tension tower to complete the short circuit. After the operation is completed, use the insulating rod to push the unlocking frame 8, causing the unlocking frame 8 to slide inward. The unlocking frame 8 will push the two clamping plates 5 to slide through the inclined surface between it and the clamping plate 5. After the clamping plate 5 slides, it will leave the double-sided inclined plate 3. At this time, the double-sided inclined plate 3 will be reset under the elastic force of the third spring 11. The double-sided inclined plate 3 will cause the two clamping arms 2 to slide outward and reset through the transmission rod 4, that is, to release the clamping of the fittings. The short circuit operation can be performed by pushing, which achieves the effect of increasing the short circuit speed and increasing the safety of the operation.

[0053] The second step is to remove the conductive component by rotating the threaded sleeve 15 before use, since the lengths of tension insulators of different specifications vary. Replace it with a conductive component of appropriate length. During installation, tighten the threaded sleeve 15 and the conductive rod 12 to make the two double-sided helical toothed plates 3 connected by the conductor 14. The conductor 14 is bright red, which can attract the attention of the workers after the work is completed. In addition, the luminous sleeve 17 can light up during nighttime work to remind the workers, thus preventing the workers from forgetting to remove the device.

[0054] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
