Description

Technical Field

[0001] This invention belongs to the field of electrical equipment maintenance and safety technology in power systems, and specifically relates to a tool for quickly hanging and installing air switch signs. Background Technology

[0002] In the daily inspection and maintenance of electrical equipment in the power system, the air switch is the core control element for circuit switching. Before maintenance, safety signs such as "Do Not Close the Switch, People Working" must be hung to warn on-site personnel to strictly prohibit accidental operation of closing the switch and to prevent safety accidents such as electric shock and equipment short circuit. This is one of the core procedures of standardized electrical maintenance.

[0003] Currently, the installation of circuit breaker signs mostly relies on manual hanging, which presents the following problems in actual operation: 1. Insecure installation: The sign is easily detached due to external force or its own weight, causing the warning to become ineffective.

[0004] 2. Lack of dual warnings: If operators forget to hang the warning signs and there are no other obvious warning measures on site, there is a safety hazard.

[0005] 3. Inability to quickly locate: Lack of specialized tools leads to low installation efficiency and affects maintenance progress.

[0006] Therefore, there is an urgent need for an installation tool that can quickly and securely hang signs and has auxiliary warning functions to improve the safety and ease of operation on site. Summary of the Invention

[0007] To address the aforementioned deficiencies in existing technologies, this invention provides a quick-hanging installation tool for air switch signs, comprising a housing, an upper clamping plate and a lower clamping plate, a gear sleeve, a rotating rod, and a hook. Through holes are provided at the right end of the top and the left end of the bottom of the housing. The upper and lower clamping plates are located at the upper and lower ends of the housing, respectively. A first lifting rod is fixed to the left end of the top of the lower clamping plate, and a second lifting rod is fixed to the right end of the bottom of the upper clamping plate. The first and second lifting rods pass through corresponding through holes and are inserted into the housing. The gear sleeve is installed on the front end face of the housing. The rear end of the rotating rod passes through the gear sleeve and is rotatably connected to the housing. The rotating rod is connected to the first and second lifting rods via a transmission assembly. The hook is fixed to the front end of the rotating rod.

[0008] Preferably, the transmission assembly includes a drive gear fixed on the rotating rod, a first driven gear and a second driven gear meshing on the left and right sides of the drive gear, a first rack fixed on the right side of the first lifting rod and a second rack fixed on the left side of the second lifting rod. The axles of the first driven gear and the second driven gear are rotatably connected to the side wall of the housing. The first rack meshes with the first driven gear and the second rack meshes with the second driven gear.

[0009] Preferably, both the first and second lifting rods have iron heads at their ends, and magnetic blocks are provided in the housing at positions corresponding to the iron heads of the first and second lifting rods.

[0010] Preferably, the inner sides of the two through holes of the housing are provided with guide grooves, and guide pulley groups are provided in the guide grooves. The guide grooves and guide pulley groups are used to guide the up and down movement of the first lifting rod and the second lifting rod.

[0011] Preferably, limiting blocks are provided on both the left and right sides of the first and second lifting rods to limit the up and down movement of the first and second lifting rods.

[0012] Preferably, the weight of the lower clamping plate is greater than that of the upper clamping plate. When the iron head is separated from the magnetic force of the magnetic block, the lower clamping plate moves downward under its own weight, while the upper clamping plate is driven upward through the transmission component until the limit block touches the guide groove and stops moving, thus playing the role of automatic reset.

[0013] Preferably, both the upper and lower clamping plates are provided with anti-slip rubber pads at the ends away from the shell. The anti-slip rubber pads can play a role in preventing slipping, wear resistance and insulation.

[0014] Preferably, a warning box is provided on the front end face of the housing, and the warning box is located on the right side of the gear sleeve. A transparent observation window is provided on the front end face of the warning box. The upper and lower ends of the warning box are respectively rotatably connected to an active conveyor roller and a driven conveyor roller. A transmission belt is connected between the active conveyor roller and the driven conveyor roller, and the front end face of the transmission belt faces the observation window. A warning mark is provided on one end face of the transmission belt, and no pattern is provided on the other end face.

[0015] Preferably, the active conveyor roller is connected to a rotating shaft, which is connected to the rotating rod via a bevel gear transmission pair, and the bevel gear transmission pair is disposed in a gear sleeve.

[0016] Preferably, the bevel gear transmission pair includes a first bevel gear and a second bevel gear that mesh with each other, the first bevel gear being fixed on the rotating rod and the second bevel gear being fixed on the rotating shaft.

[0017] This invention also includes other components that enable the quick-installation tool for air switch signs to function properly, all of which are conventional techniques in the art. Furthermore, any devices or components not specified in this invention employ conventional techniques in the art.

[0018] The working principle of this invention is: Before installing this device onto the air switch, the hook should be in the vertical upward position, with the upper and lower clamps open upward and downward respectively. At this time, the transmission belt in the warning box should be flipped to the side without patterns.

[0019] When installing this device onto the air switch, align the upper and lower clamps with the upper and lower ends of the air switch, respectively. Then, rotate the hook counterclockwise. The rotating rod drives the drive gear to rotate, which in turn drives the first driven gear to rotate clockwise and the second driven gear to rotate counterclockwise. This causes the first lifting rod to move the lower clamp upward and the second lifting rod to move the upper clamp downward, until the hook rotates to the vertical downward position. At this point, the iron heads of the first and second lifting rods are attracted to the corresponding magnetic blocks. Simultaneously, the upper and lower clamps can clamp the upper and lower ends of the air switch, using magnetic attraction to hold the upper and lower clamps in place. Position the sign; once fixed, hang the lanyard of the warning sign on the hook for its warning function. Simultaneously, during the installation process, the active transmission roller in the warning box rotates under the transmission of the bevel gear drive pair and the rotating shaft, and drives the driven transmission roller to rotate via the transmission belt. This flips the end of the transmission belt with the warning sign to face the observation window, providing a double warning effect along with the warning sign. In this way, even if staff forget to hang the warning sign due to operational error, the warning box itself will serve as a reminder, reducing safety risks, improving safety, and increasing the margin for error in operation.

[0020] After maintenance, remove the warning sign and rotate the hook clockwise to disengage the iron heads of the first and second lifting rods from their corresponding magnetic blocks. Then, the lower clamping plate moves downward under its own weight, while the upper clamping plate moves upward through the transmission assembly until the limit block touches the guide groove and stops moving, thus achieving automatic reset. At the same time, the active conveyor roller in the warning box...

[0021] The beneficial effects of this invention are: (1) Easy to operate and secure clamping: By rotating the hook to drive the gear and rack transmission assembly, the upper and lower clamps can be clamped or released synchronously, which can quickly and firmly clamp the upper and lower ends of the air switch and prevent the label from falling off.

[0022] (2) Automatic reset function: The lower clamping plate is heavier than the upper clamping plate. Combined with the attraction design of the iron head and the magnetic block, the hook can be automatically reset by rotating it clockwise after maintenance, which simplifies the operation steps and improves the efficiency of use.

[0023] (3) Dual warning mechanism to enhance safety: The tool is equipped with a warning box at the front end. During the clamping process, the warning sign on the transmission belt is automatically flipped to the observation window position. Even if the operator forgets to hang the sign, the warning box can provide a visual warning to reduce the risk of misoperation.

[0024] (4) Compact structure and strong adaptability: The design of guide groove, guide pulley group and limit block ensures smooth movement of the lifting rod; the anti-slip rubber pad can increase friction and play an insulating role.

[0025] (5) Integrated design, easy to carry and use: The hook can both drive the clamping action and hang the sign. The overall structure is compact, making it easy to carry on site and operate with one hand. Attached Figure Description

[0034] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely illustrative and is not intended to limit the scope of the invention. Any modifications, equivalent substitutions, or improvements made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the scope of protection of the present invention.

[0035] Example like Figure 1-6As shown, this embodiment of the invention provides a quick-hanging installation tool for air switch signs, including a housing 1, an upper clamping plate 2 and a lower clamping plate 3, a gear sleeve 4, a rotating rod 5, a hook 6, and a warning box 7. Through holes are provided at the right end of the top and the left end of the bottom of the housing 1. The upper clamping plate 2 and the lower clamping plate 3 are located at the upper and lower ends of the housing 1, respectively. A first lifting rod 8 is fixed to the left end of the top of the lower clamping plate 3, and a second lifting rod 9 is fixed to the right end of the bottom of the upper clamping plate 2. The first lifting rod 8 and the second lifting rod 9 pass through the corresponding through holes and are inserted into the housing 1. The gear sleeve 4 is installed on the front end face of the housing 1. The rear end of the rotating rod 5 passes through the gear sleeve 4 and is rotatably connected to the housing 1. 5 is connected to the first lifting rod 8 and the second lifting rod 9 respectively through the transmission assembly 10, and the hook 6 is fixed to the front end of the rotating rod 5. It should be further explained that the transmission assembly 10 includes a driving gear 11 fixed on the rotating rod 5, a first driven gear 12 and a second driven gear 13 meshing with the left and right sides of the driving gear 11, a first rack 14 fixed on the right side of the first lifting rod 8 and a second rack 15 fixed on the left side of the second lifting rod 9. The axles of the first driven gear 12 and the second driven gear 13 are rotatably connected to the side wall of the housing 1. The first rack 14 meshes with the first driven gear 12, and the second rack 15 meshes with the second driven gear 13.

[0036] The warning box 7 is located on the right side of the gear sleeve 4. A transparent observation window 16 is provided on the front end face of the warning box 7. The upper and lower ends of the warning box 7 are respectively rotatably connected to the active conveyor roller 17 and the driven conveyor roller 18. A transmission belt 19 is connected between the active conveyor roller 17 and the driven conveyor roller 18, and the front end face of the transmission belt 19 faces the observation window 16. A warning sign 20 is provided on one end face of the transmission belt 19, and the other end face is blank.

[0037] The active conveyor roller 17 is connected to a rotating shaft 21. The rotating shaft 21 is connected to the rotating rod 5 via a bevel gear transmission pair 22. The bevel gear transmission pair 22 is located in the gear sleeve 4. Specifically, the bevel gear transmission pair 22 includes a meshing first bevel gear and a second bevel gear. The first bevel gear is fixed on the rotating rod 5, and the second bevel gear is fixed on the rotating shaft 21.

[0038] In addition, both the ends of the first lifting rod 8 and the second lifting rod 9 are provided with iron heads 23, and magnetic blocks 24 are provided in the housing 1 at positions corresponding to the iron heads 23 of the first lifting rod 8 and the second lifting rod 9. Guide grooves 25 are provided on the inner sides of the two through holes of the housing 1, and guide pulley groups 26 are provided in the guide grooves 25. The guide grooves 25 and guide pulley groups 26 are used to guide the up-and-down movement of the first lifting rod 8 and the second lifting rod 9. Limiting blocks 27 are provided on the left and right sides of the first lifting rod 8 and the second lifting rod 9 to limit their up-and-down movement. The weight of the lower clamping plate 3 is greater than the weight of the upper clamping plate 2. It should be noted that when the iron heads 23 are released from the magnetic force of the magnetic blocks 24, the lower clamping plate 3 moves downward under its own weight, while simultaneously driving the upper clamping plate 2 upward through the transmission assembly 10, until the limiting blocks 27 touch the guide grooves 25 and stop moving, thus achieving automatic reset. Both the upper clamping plate 2 and the lower clamping plate 3 are provided with anti-slip rubber pads 28 at the ends away from the housing 1. The anti-slip rubber pads 28 can play the role of anti-slip, wear resistance and insulation.

[0039] The working principle of this invention is: Before installing this device onto the air switch 29, the hook 6 is in the vertical upward position, and the upper clamp 2 and lower clamp 3 are opened upward and downward respectively. At this time, the transmission belt 19 in the warning box 7 is flipped to the side without patterns.

[0040] When installing this device onto the air switch 29, align the upper clamp 2 and lower clamp 3 with the upper and lower ends of the air switch 29, respectively. Then, rotate the hook 6 counterclockwise. The rotating rod 5 rotates, driving the drive gear 11 to rotate, which in turn drives the first driven gear 12 to rotate clockwise and the second driven gear 13 to rotate counterclockwise. This causes the first lifting rod 8 to move the lower clamp 3 upward and the second lifting rod 9 to move the upper clamp 2 downward. After the hook 6 rotates to the vertical downward position, the iron heads 23 of the first lifting rod 8 and the second lifting rod 9 are attracted to the corresponding magnetic blocks 24. At the same time, the upper clamp 2 and lower clamp 3 can just hold the upper and lower ends of the air switch 29, using magnetic attraction to hold the upper clamp 2 and lower clamp 3 in place. The clamp 3 is used for positioning; after it is fixed, the hanging rope of the warning sign 30 is hung on the hook 6 to serve as a warning; at the same time, during the above installation process, the active transmission roller 17 in the warning box 7 rotates under the transmission action of the bevel gear transmission pair 22 and the rotating shaft 21, and drives the driven transmission roller 18 to rotate through the transmission belt 19, flipping the end face of the transmission belt 19 with the warning sign 20 to face the observation window 16, which, together with the warning sign 30, serves as a double warning. In this way, even if the staff forgets to hang the warning sign 30 due to operational errors, the warning box 7 itself can serve as a reminder, reducing safety risks, improving safety, and increasing the operational error tolerance rate.

[0041] After maintenance, remove the warning sign 30 and rotate the hook 6 clockwise to disengage the iron heads 23 of the first lifting rod 8 and the second lifting rod 9 from their corresponding magnetic blocks 24. Then, the lower clamping plate 3 moves downward under its own weight, while the upper clamping plate 2 is driven upward by the transmission component 10 until the limit block 27 touches the guide groove 25 and stops moving, thus achieving automatic reset. At the same time, the active conveying roller 17 in the warning box 7...

[0042] The embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
