Description

Technical Field

[0001] The present application relates to the technical field of power protective gear, and in particular to a safety rope for electrical maintenance. Background Art

[0002] The safety rope is woven with synthetic fibers and is an auxiliary rope used to connect to a safety belt. When power maintenance personnel perform aerial work, they need to use two or more sets of safety ropes alternately to ensure personal safety. Traditional safety rope hooks are mostly simple in structure and can be locked relatively easily. However, once maintenance personnel make a mistake and open multiple sets of safety ropes at the same time, it will cause serious safety hazards.

[0003] To this end, Chinese patent application CN112569496A discloses a safety rope with a snap-fit ​​mechanism for circuit maintenance, which is provided with a fixed rope and a pressure-bearing rope. The fixed rope and the pressure-bearing rope are made of elastic woven belt material, so that the device can adapt to the body shapes of different users during use, and the device is fixed with a buckle when worn, and the use process is simple and convenient, which improves the convenience and practicality of the device; and the safety rope is provided with an auxiliary pin, a fixed rod and a locking block. When the hook body and the fixed rod are in the locking body, the auxiliary pin must be inserted into the hook body, and the locking block must be pushed to release the lock of the opening and closing rod before the opening device of the opening and closing rod can be pulled, so that the electrician cannot simply open the two sets of hooks during use, which ensures the safety of the electrician when in use and improves the safety and practicality of the device. However, the locking block structure is relatively simple and cannot be self-locking. When the maintenance personnel press the opening and closing rod without using the auxiliary pin, a large force can be used to push the locking block through the opening and closing rod, and then open the hook mechanism. When the opening and closing rod is reset by the elastic force of the fixed spring, it will be blocked by the locking block, causing a conflict, so that it cannot be closed normally, resulting in it not being able to play a normal safety role. In addition, the hook mechanism can be automatically reset. When the operator performs the locking action, if the hook has not been successfully buckled on the rod body or the hook is not fully opened, the operator releases the opening and closing rod, and the opening and closing rod is reset under the elastic force of the fixed spring, which will cause it to be unable to buckle on the rod body normally, and thus cannot play a protective role. To this end, the present invention proposes a safety rope for electrical maintenance. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0062] This application provides an embodiment of a safety rope for electrical maintenance. Figures 1 to 3 as well as Fig. 9 .

[0063] The safety rope for electrical maintenance in this embodiment includes: a main rope 1, to which a secondary rope 11 is connected, and a hook mechanism 2 is installed at the end of the secondary rope 11 away from the main rope 1, the hook mechanism 2 includes a main body 21 and a buckle 22, the main body 21 is annular, the buckle 22 is slidably installed on the main body 21, and a locking mechanism 3 is arranged on the main body 21, and the locking mechanism 3 includes a guide component 31 and a locking component 32, the guide component 31 is installed on the main body 21, and is used to guide the sliding of the buckle 22; the locking component 32 is arranged on the main body 21, and is used to fix the buckle 22.

[0064] It should be noted that the safety rope used for electrical maintenance realizes the function of maintaining the state of the hook mechanism 2 through the main rope 1, the hook mechanism 2 and the locking mechanism 3, thereby preventing it from changing its opening and closing state by itself, and solving the problem that the hook of the traditional safety rope will still close by itself when no object is hung on it, causing safety accidents.

[0065] The above is an embodiment of a safety rope for electrical maintenance provided in the embodiment of the present application. The following is an embodiment of a safety rope for electrical maintenance provided in the embodiment of the present application. For details, please refer to Figures 1 to 9 .

[0066] The safety rope for electrical maintenance in this embodiment includes: a main rope 1, a secondary rope 11 is connected to the main rope 1, a hook mechanism 2 is installed at one end of the secondary rope 1 away from the main rope 1, the hook mechanism 2 includes a main body 21 and a buckle 22, the main body 21 is annular, the buckle 22 is slidably installed on the main body 21, and a locking mechanism 3 is provided on the main body 21. The locking mechanism 3 includes a guide component 31 and a locking component 32. The guide component 31 is installed on the main body 21 to guide the sliding of the buckle 22; the locking component 32 is arranged on the main body 21 to fix the buckle 22. Specifically, at least two secondary ropes 11 are provided, and the buckle 22 has two states of opening and closing under the guidance of the guide component 31.

[0067] It should be noted that: the safety rope realizes the function of maintaining the state of the hook mechanism 2 through the main rope 1, the hook mechanism 2 and the locking mechanism 3, so as to prevent it from changing the opening and closing state by itself, and solves the problem that the hook of the traditional safety rope will still close by itself when no object is hung, causing safety accidents. In order to ensure the safety of high-altitude operations, the operator needs to hang the hook mechanism 2 on the rod body (the rod body is not shown in the figure). When using it, the operator first releases the lock of the locking component 32, and then slides the buckle 22. When sliding to a position close to the opening position, the buckle 22 will slide to a fully open state by itself under the guidance of the guide component 31, so as to avoid the situation that the buckle 22 is not fully opened. Then the hook mechanism 2 is buckled on the rod body, and then the buckle 22 is slid again. The buckle 22 slides to a closed state under the guidance of the guide component 31 and is hung on the rod body. At the same time, the locking component 32 fixes the buckle 22 to play a protective role. Compared with the traditional hook, the cooperation of the guide component 31 and the locking component 32 can prevent the buckle 22 from being not fully opened, resulting in the inability to smoothly hang on the rod body. At the same time, through the fixation of the locking component 32, the hook can maintain the current state and play a role in stable protection.

[0068] like Figure 2 , Figure 6 , Figure 7 as well as Fig. 9 As shown, the guide assembly 31 includes a mounting box 311, a telescopic rod 312, a first elastic member 313 and a guide block 314. The mounting box 311 is mounted on the main body 21. The end of the buckle 22 close to the mounting box 311 is provided with a mounting seat 221. The telescopic rod 312 is slidably mounted on the mounting seat 221. The two ends of the first elastic member 313 are respectively connected to the telescopic rod 312 and the mounting seat 221. The guide block 314 is mounted in the mounting box 311, and the guide block 314 abuts against the telescopic rod 312. Specifically, the guide block 314 is an arc-shaped structure with a thick middle and thin sides.

[0069] It should be noted that the function of guiding the movement of the buckle 22 is achieved through the installation box 311, the telescopic rod 312, the first elastic member 313 and the guide block 314, so as to prevent the buckle 22 from being incompletely opened and closed. During use, the operator first releases the lock of the locking assembly 32, and then slides the buckle 22. The buckle 22 drives the mounting seat 221 to move synchronously, and the mounting seat 221 drives the telescopic rod 312 to move. As the telescopic rod 312 moves, it is tightly matched with the guide block 314 under the elastic force of the first elastic member 313, and as the telescopic rod 312 moves, the first elastic member 313 is squeezed and contracts. After it passes the middle position of the guide block 314, it will slide along the guide block 314 under the elastic force of the first elastic member 313 until the buckle 22 is in a fully open state. At this time, the hook mechanism 2 can be buckled on the rod body, and then the buckle 22 is slid again. Similarly, the guiding effect of the buckle 22 in the guide assembly 31 The hook mechanism 2 can be easily opened by the operator by sliding it downward to a closed state and hanging it on the rod body. At the same time, the locking assembly 32 fixes the buckle 22 to play a protective role. During the use of the hook mechanism 2, if the operator does not slide the buckle 22 to a certain position, the buckle 22 will not open, and it will reset under the elastic force of the first elastic member 313. At the same time, through the guidance of the guide block 314, the buckle 22 can maintain the current open and closed state until the operator slides it manually. After hanging it on the rod body, the operator needs to close it manually. During this process, the installation status of the hook mechanism 2 can be checked, thereby ensuring the working stability of the hook mechanism 2 and avoiding the situation where the remaining hook mechanisms 2 are opened before they are stably installed, which can fully protect the personal safety of the users.

[0070] like Figure 2 , Figure 6 as well as Figure 7 As shown, the locking assembly 32 includes a mounting block 322, a locking block 323 and a second elastic member 324. The mounting block 322 is mounted on the end of the telescopic rod 312 away from the mounting seat 221. The locking block 323 is slidably mounted on the mounting block 322. The two ends of the second elastic member 324 are respectively connected to the locking block 323 and the mounting block 322. A locking groove 321 for cooperating with the locking block 323 is provided on the mounting box 311.

[0071] It should be noted that the function of fixing the position of the buckle 22 is achieved through the locking groove 321, the mounting block 322, the locking block 323 and the second elastic member 324, so as to prevent the buckle 22 from sliding by itself under the action of external force, and further ensure the personal safety of the user. During use, the operator first unlocks the locking assembly 32, and then slides the buckle 22. The buckle 22 drives the mounting seat 221 to move synchronously, and the mounting seat 221 drives the telescopic rod 312 to move. As the telescopic rod 312 moves, it is tightly fitted with the guide block 314 under the elastic force of the first elastic member 313, and as the telescopic rod 312 moves, the first elastic member 313 is squeezed and contracts. After it passes the middle position of the guide block 314, it will follow the guide block 314 under the elastic force of the first elastic member 313. 4 until the buckle 22 is in a fully open state. At this time, the hook mechanism 2 can be buckled on the rod body, and then the buckle 22 is slid again. Similarly, the buckle 22 slides to a closed state under the guidance of the guide assembly 31, and is finally successfully hung on the rod body. At the same time, when the buckle 22 is in a closed state, the locking block 323 slides into the locking groove 321 under the elastic force of the second elastic member 324, and the position of the buckle 22 is fixed by the cooperation of the locking block 323 and the locking groove 321, so as to further prevent the buckle 22 from opening by itself under the action of external force.

[0072] like Figure 3 , Figure 4 , Figure 5 as well as Figure 8 As shown, a control mechanism 4 is also provided on the installation box 311, and the control mechanism 4 includes an unlocking component 41 and a control component 42. The unlocking component 41 includes a control plate 411 and a docking block 412. The control plate 411 is slidably installed on the installation box 311, and the docking block 412 is installed on the control plate 411. The shape of the docking block 412 is matched with the shape of the locking groove 321. The control component 42 is installed on the installation box 311 and is used to move the control plate 411.

[0073] It should be noted that the unlocking component 41 and the control component 42 are used to release the locking component 32 from the buckle 22 , thereby facilitating the operator to alternately use the hook mechanism 2 . When the buckle 22 is in the closed state, the locking block 323 will slide into the locking groove 321 under the elastic force of the second elastic member 324, and the position of the buckle 22 will be fixed by the cooperation of the locking block 323 and the locking groove 321, so as to prevent the buckle 22 from opening by itself under the action of external force. When the operator needs to open the buckle 22, the control plate 411 can be slid through the control assembly 42, and the control plate 411 can be used to drive the docking block 412 to move, so that the docking block 412 squeezes the locking block 323, overcomes the elastic force of the second elastic member 324 to drive the locking block 323 to move, so that the locking block 323 slides out of the locking groove 321, thereby releasing the movement restriction of the buckle 22, and then the operator can slide the buckle 22 to open it.

[0074] like Figure 3 , Figure 4 , Figure 5 as well as Figure 8 As shown, the control component 42 includes a fixed rack 421, a rotating shaft 422 and a first rotating gear 423. The fixed rack 421 is connected to the control plate 411. The rotating shaft 422 is rotatably mounted on the mounting box 311. The first rotating gear 423 is coaxially fixed on the rotating shaft 422. The fixed rack 421 is transmission-connected to the first rotating gear 423. A rotating drive component 43 for driving the rotating shaft 422 to rotate is also provided on the mounting box 311.

[0075] It should be noted that the function of driving the control plate 411 to move is realized by fixing the rack 421, the rotating shaft 422, the first rotating gear 423 and the rotating drive assembly 43. Specifically, when the operator slides the buckle 22, the buckle 22 will slide to the closed state under the guidance of the guide assembly 31 and hang on the rod body. At the same time, when the buckle 22 is in the closed state, the locking block 323 will slide into the locking groove 321 under the elastic force of the second elastic member 324. The position of the buckle 22 is fixed by the cooperation of the locking block 323 and the locking groove 321 to prevent the buckle 22 from opening by itself under the action of external force. When the operator needs to open the buckle 22, the rotating shaft 422 can be driven to rotate by the rotating drive assembly 43. The rotating shaft 422 is used to drive the first rotating gear 423 to rotate, and the first rotating gear 423 drives the fixed rack 421 connected thereto to move, and the fixed rack 421 drives the control plate 411 to slide, and the control plate 411 drives the docking block 412 to move, so that the docking block 412 squeezes the locking block 323, overcomes the elastic force of the second elastic member 324 and drives the locking block 323 to move, so that the locking block 323 slides out of the locking groove 321, thereby releasing the movement restriction of the buckle 22, and then the operator can slide the buckle 22 to open it.

[0076] like Figure 4 and Figure 8 As shown, the rotation drive assembly 43 includes a second rotation gear 431 coaxially fixed on the rotation shaft 422 and a moving rack 432 for driving the second rotation gear 431, and the moving rack 432 is meshedly connected with the second rotation gear 431. Specifically, the moving rack 432 is detachably slidably mounted on the mounting box 311, and the moving rack 432 is detachably connected to the second rotation gear 431.

[0077] It should be noted that: the function of driving the rotating shaft 422 to rotate is realized by the second rotating gear 431 and the movable rack 432, so as to achieve the effect of driving the control plate 411 to move. Specifically, when it is necessary to open the hook mechanism 2, the operator needs to take out the movable rack 432, and then insert the movable rack 432 into the installation box 311, and the second rotating gear 431 is driven to rotate by the movement of the movable rack 432, and the second rotating gear 431 drives the rotating shaft 422 to rotate, and the rotating shaft 422 drives the first rotating gear 423 to rotate, and the first rotating gear 423 drives the fixed rack 421 connected thereto to move, and the fixed rack 421 drives the control plate 411 to slide, and the control plate 411 drives the docking The block 412 moves, so that the docking block 412 squeezes the locking block 323, overcomes the elastic force of the second elastic member 324 and drives the locking block 323 to move, so that the locking block 323 slides out of the locking groove 321, thereby releasing the movement restriction of the buckle 22, and then the operator can slide the buckle 22 to open it; by setting the movable rack 432, the operator needs to insert the movable rack 432 into the hook mechanism 2 that needs to be opened, and thus the operator cannot open the two hook mechanisms 2 at the same time, thereby further improving safety.

[0078] like Figure 4 As shown, a protective cover 44 is rotatably connected to the installation box 311 , and a first handle 441 is provided on the protective cover 44 .

[0079] It should be noted that the protective cover 44 and the first handle 441 realize the function of protecting the control component 42 and the rotation drive component 43, and the first handle 441 achieves the effect of quickly opening the installation box 311. When the control component 42 and the rotation drive component 43 need to be inspected, the operator only needs to grasp the first handle 441 and open the protective cover 44, and then the parts in the installation box 311 can be inspected. After the inspection is completed, the operator closes the protective cover 44 to protect the parts in the installation box 311.

[0080] like Figure 4 , Figure 5 as well as Figure 8 As shown, the unlocking assembly 41 further includes a return spring 413 , and two ends of the return spring 413 are respectively connected to the main body 21 and the control sheet 411 .

[0081] It should be noted that the function of keeping the locking assembly 32 open without external force is achieved by the return spring 413. When the operator does not unlock the locking assembly 32 through the unlocking assembly 41, the control piece 411 will move in a direction away from the locking groove 321 under the elastic force of the return spring 413, so that the locking assembly 32 can play the original locking function, fix the position of the buckle 22, and maintain the working stability of the hook mechanism 2.

[0082] like Figure 6 and Figure 8 As shown, a pressure sensor 325 is also installed in the installation box 311, and a vibration motor 326 is provided on the installation box 311. Specifically, the pressure sensor 325 is block-shaped, and when the buckle 22 is in the open state, the locking block 323 just contacts the pressure sensor 325.

[0083] It should be noted that the function of sensing the state of the hook mechanism 2 is realized by the pressure sensor 325. The pressure sensor 325 and the vibration motor 326 are electrically connected to the controller; when the buckle 22 is in the open state, the telescopic rod 312 drives the mounting block 322 and the guide block 314 to fit tightly under the elastic force of the first elastic member 313, and after the locking block 323 and the pressure sensor 325 fit tightly, the pressure sensor 325 feeds back a signal to the controller, and the controller sends a signal to the vibration motor 326 after receiving the signal, and the vibration motor 326 sends a vibration signal after receiving the signal.

[0084] like Figure 2 and Fig. 9 As shown, a second handle 23 is installed on the buckle 22, and the second handle 23 realizes the function of facilitating the operator to slide the buckle 22. When sliding the buckle 22, the operator holds the second handle 23 and then slides the buckle 22. During use, the operator needs to slide the buckle 22 frequently, and the second handle 23 improves the operator's operation portability.

[0085] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application 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 make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
