Description

Technical Field

[0001] The present invention relates to the technical field of valve locking, and in particular to a multifunctional valve locker and a use method thereof. Background Art

[0002] With the continuous advancement of industrial technology, the equipment and pipelines in factories have become more complex, and the types of valve locks required for daily operation and maintenance have increased, which has brought unprecedented challenges to the maintenance and management of valves.

[0003] Traditional valve locking methods require factories to prepare multiple locks for different valve types. Each lock corresponds to a specific valve type and has unique specifications and interfaces. When workers perform inspections or routine maintenance, they need to spend a considerable amount of time and effort selecting the correct type and size of lock to ensure reliable locking of the target valve. This process is not only cumbersome but also increases the risk of operational errors. Furthermore, because each lock is equipped with a specific key, workers need to carry a large number of keys to operate locks and valves when inspecting related machinery and equipment or performing other complex tasks. This management method is not only inefficient but also carries the risk of key loss or confusion. To reduce the occurrence of these problems, most factories require detailed registration of key use, which seriously affects work efficiency.

[0004] In addition to the inconveniences of management and operation, traditional locks also present a problem: while locking the valve, they obscure the valve status indicator. This makes it difficult for workers to accurately determine the actual status of the pipeline during maintenance or testing, affecting the accuracy and efficiency of maintenance and even posing serious safety hazards. For example, if a valve is mistakenly identified as open when locked, it could lead to a dangerous situation during related operations. Summary of the Invention

[0033] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0034] Please refer to Figures 1 to 8, a multifunctional valve locker, comprising a handle clamping device and a limiting device for fixing the handle clamping device;

[0035] The limiting device includes a smart lock component 1 and a fastening ring 2. The smart lock component 1 is arranged on the fastening ring 2, and the smart lock component 1 is used to adjust the inner ring diameter of the fastening ring 2;

[0036] The clamping device includes a locking rod 3 and a movable clamp 4;

[0037] The movable pliers 4 are arranged on one end of the locking rod 3. The width of the jaws of the movable pliers 4 is adjustable, the length of the locking rod 3 is adjustable, and the other end of the locking rod 3 is locked and connected to the limiting device.

[0038] When the locking rod 3 is locked with the limiting device, the plane where the fastening collar 2 is located is parallel to the locking rod 3;

[0039] The fastening collar 2 is used for being sleeved and fixed on the valve body 5 or its matching pipeline, and the movable pliers 4 are used for clamping the valve handle 6 .

[0040] From the above description, it can be seen that the beneficial effect of the present invention is that the fastening ring 2 is locked and fixed on the valve body 5 or its supporting pipeline through the smart lock component 1, providing a limiting basis for the clamping device, and the clamping device specifically uses the movable clamp 4 on the locking rod 3 to clamp the valve handle 6. Specifically, by adjusting the jaw size of the movable clamp 4 and the length of the locking rod 3, it can be applied to various types of valves. At the same time, the position of the locking rod 3 is adjusted to be locked in position with the limiting device, so as to limit the movement of the locking rod 3 by relying on the fastening ring 2, maintain the clamping effect of the movable clamp 4, and lock the valve without blocking the valve status indicator; when unlocking is required, just unlock the smart lock component 1 and loosen the fastening ring 2, which is highly safe and easy to operate.

[0041] Furthermore, the fastening collar 2 is formed by being embraced by a connecting belt 21;

[0042] The smart lock assembly 1 is provided with a mounting hole 13 for the connecting belt 21 to pass through, and a fastening control member is provided in the smart lock assembly 1 at a position corresponding to the mounting hole 13;

[0043] The fastening control member is engaged with the connecting belt 21 .

[0044] As can be seen from the above description, the fastening collar 2 is formed by the connecting belt 21; when unlocking, the two ends of the connecting belt 21 can be separated by releasing the clamping connection between the fastening control part and the connecting belt 21, so that the fastening collar 2 can be completely separated from the valve body 5, making the movement of the locking rod 3 more flexible. At the same time, the two ends of the annular structure formed by the connecting belt 21 can overlap, making it easier to adjust the inner ring diameter of the fastening collar 2.

[0045] Furthermore, the fastening control member includes a control member and a rotating gear 7, the rotating gear 7 is rotatably arranged in the smart lock assembly 1, and a sawtooth bar 22 is provided on the connecting belt 21, and the rotating gear 7 is engaged with the connecting belt 21 through the sawtooth bar 22 for transmission;

[0046] The control member is in transmission connection with the rotating gear 7 and is used to control the rotation of the rotating gear 7.

[0047] From the above description, it can be seen that a serrated bar 22 is provided on the connecting belt 21, so that the connecting belt 21 is controlled to pass through the smart lock assembly 1 by relying on the meshing transmission between the rotating gear 7 and the serrated bar 22, thereby changing the size of the fastening ring 2 formed by the connecting belt 21, and relying on the control part to fix the rotating gear 7 to prevent it from rotating, so as to jam the connecting belt 21. Its composition structure is simple and the transmission process is stable.

[0048] Furthermore, the limiting device further includes at least two limiting seats 8;

[0049] The limiting seat 8 is provided with the mounting hole 13, and the limiting seat 8 is sleeved on the connecting belt 21 through the mounting hole 13;

[0050] The limiting seat 8 is locked to the end of the locking rod 3 away from the movable clamp 4.

[0051] From the above description, it can be seen that in order to flexibly fix the locking rod 3 and increase the applicable range of the locking period, a plurality of limit seats 8 with mounting holes 13 are provided, and the limit seats 8 are sleeved on the fastening ring 2 through the mounting holes 13. After the fastening ring 2 is sleeved on the valve body 5, the position of the limit seat 8 can be adjusted according to the actual positional relationship between the valve handle 6 and the valve body 5, so that it can be aligned and locked with the locking rod 3.

[0052] Furthermore, the limiting seat 8 is provided with a rotating wheel 10 located in the mounting hole 13;

[0053] The rotating wheel 10 is meshedly connected with the sawtooth bar 22 .

[0054] From the above description, it can be seen that a rotating wheel 10 is set in the limit seat 8 so as to form a matching fit with the serrated bar 22 of the connecting belt 21. When adjusting the position of the limit seat 8, the rotating wheel 10 is transmitted on the serrated bar 22, so that after the adjustment is completed, the position of the limit seat 8 can be initially maintained stationary, thereby improving the convenience of installing the lock.

[0055] Furthermore, the limiting device further includes an elastic resistance component 9;

[0056] The elastic resistance component 9 is provided on one side of the smart lock component 1 facing the inner ring of the fastening ring 2 and on one side of the limit seat 8 facing the inner ring of the fastening ring 2;

[0057] The elastic resistance component 9 is provided with at least two elastic resistance movable ends, and the elastic resistance movable ends are used to abut against the valve body 5 .

[0058] From the above description, it can be seen that during installation, the elastic resistance component 9 is in contact with the outer side of the valve body 5, and multiple elastic resistance movable ends are provided, which can flexibly follow the shape of the outer side surface of the valve body 5 and fit perfectly, thereby improving the stability effect.

[0059] Furthermore, the elastic resistance component 9 includes a base 91, at least two return springs 92 and at least two cluster heads 93;

[0060] The base 91 is provided on one side of the smart lock assembly 1 facing the inner ring of the fastening ring 2 and on one side of the limit seat 8 facing the inner ring of the fastening ring 2;

[0061] The base 91 is provided with a limiting groove 94 , one end of the cluster head 93 is fixed in the limiting groove 94 by the return spring 92 in a one-to-one correspondence, and the other end of the cluster head 93 is used to abut the valve body 5 .

[0062] From the above description, it can be seen that the elastic abutting movable end is composed of a one-to-one corresponding cluster head 93 and a return spring 92. When abutting the valve body 5, the expansion and contraction change of the return spring 92 produces and maintains the contouring and fitting effect.

[0063] Furthermore, the movable pliers 4 include a first pliers arm 41 , a second pliers arm 42 and a tightening spring 43 ;

[0064] The first clamp arm 41 and the second clamp arm 42 are arranged parallel to each other on the locking rod 3, and the second clamp arm 42 can be slidably arranged on the locking rod 3 in a direction close to or away from the first clamp arm 41;

[0065] The tightening spring 43 is disposed between the first clamp arm 41 and the second clamp arm 42 , and two ends of the tightening spring 43 are connected to the first clamp arm 41 and the second clamp arm 42 respectively.

[0066] From the above description, it can be seen that the distance between the first clamp arm 41 and the second clamp arm 42 is adjusted to flexibly cope with valve handles 6 of different sizes; and while adjusting the distance, the tightening spring 43 is stretched, and clamping is achieved by the contraction force of the stretched tightening spring 43.

[0067] Furthermore, a mounting portion 12 is provided on the end of the locking rod 3 , and the mounting portion 12 is connected to one end of the locking rod 3 of the other clamping device.

[0068] From the above description, it can be seen that the mounting portion 12 is provided on the locking rod 3 for connecting multiple locking rods 3, which can be used to lock valves with multiple handles or large relative position deviations between the locking rod 3 and the limiting device.

[0069] Please refer to Figure 9 A method for using a multifunctional valve locker is applied to the multifunctional valve locker described above, comprising the following steps:

[0070] S1. When locking the valve, put the fastening collar 2 on the valve body 5 and adjust the size of the fastening collar 2 through the smart lock component 1 so that the fastening collar 2 is fastened to the valve body 5;

[0071] S2. Use the movable pliers 4 to clamp the valve handle 6, while keeping the locking rod 3 perpendicular to the plane of the rotation trajectory of the valve handle 6 and the plane of the fastening ring 2 parallel to the locking rod 3; lock the locking rod 3 to the limit device;

[0072] S3. When unlocking the valve, unlock the smart lock assembly 1, loosen the fastening collar 2, move the locking rod 3, and release the clamping of the movable clamp 4 on the valve handle 6.

[0073] From the above description, it can be seen that the beneficial effect of the present invention is that the fastening ring 2 is locked and fixed on the valve body 5 or its supporting pipeline through the smart lock component 1, providing a limiting basis for the clamping device, and the clamping device specifically uses the movable clamp 4 on the locking rod 3 to clamp the valve handle 6. Specifically, by adjusting the jaw size of the movable clamp 4 and the length of the locking rod 3, it can be applied to various types of valves. At the same time, the position of the locking rod 3 is adjusted to be locked in position with the limiting device, so as to limit the movement of the locking rod 3 by relying on the fastening ring 2, maintain the clamping effect of the movable clamp 4, and lock the valve without blocking the valve status indicator; when unlocking is required, just unlock the smart lock component 1 and loosen the fastening ring 2, which is highly safe and easy to operate.

[0074] Example 1

[0075] A multifunctional valve locker, such as Figure 1 and Figure 7 As shown, it includes a handle clamping device and a limiting device for fixing the handle clamping device;

[0076] The limiting device includes an intelligent lock component 1 and a fastening ring 2. The intelligent lock component 1 is arranged on the fastening ring 2, and the intelligent lock component 1 is used to adjust the inner ring diameter of the fastening ring 2. The clamping device includes a locking rod 3 and an movable pliers 4; the movable pliers 4 are arranged on one end of the locking rod 3, the jaw width of the movable pliers 4 is adjustable, the length of the locking rod 3 is adjustable, and the other end of the locking rod 3 is locked and connected to the limiting device; when the locking rod 3 is locked and connected to the limiting device, the plane where the fastening ring 2 is located is parallel to the locking rod 3; wherein, the fastening ring 2 is used to be sleeved and fixed on the valve body 5 or its matching pipeline, and the movable pliers 4 is used to clamp the valve handle 6.

[0077] In this embodiment, if Figure 2 As shown, the smart lock assembly 1 adjusts the inner diameter of the fastening collar 2 so that the fastening collar 2 can be fixed to the valve body 5 or its corresponding pipeline. After the clamping device clamps the valve handle 6, it is locked with the limit device to limit the valve handle 6 and prevent it from rotating. The fastening collar 2 is formed by a connecting band 21. The smart lock assembly 1 has a mounting hole 13 for the connecting band 21 to pass through. The smart lock assembly 1 has a fastening control member located at the position corresponding to the mounting hole 13. The fastening control member is engaged with the connecting band 21. The connecting band 21 is flat and made of a soft material such as metal or rubber.

[0078] Regarding the smart lock component 1, the detailed description is as follows:

[0079] First, the smart lock assembly 1, as the name implies, not only has a traditional lock core structure, but can also integrate a control chip on the fastening control part; as a preferred locking solution, the control chip can record relevant information of personnel with unlocking authority, coded information corresponding to the valve, etc. Without passing the verification, the smart lock assembly 1 cannot be used to adjust the inner ring diameter of the fastening collar 2, and the limit on the valve handle 6 cannot be released; when it is necessary to turn the valve handle 6, the operator uses the electronic key to authenticate the identity on the smart lock assembly 1. After the verification is passed, the fastening collar 2 can be unlocked on the smart lock assembly 1. It should be noted that the above-mentioned identity authentication, electronic key and other contents are all achieved by relying on existing technologies or using existing smart lock products, and will not be described in detail in this embodiment.

[0080] Secondly, in addition to using a hardware-software electronic lock, the smart lock assembly 1 of this embodiment can also be used with a mechanical key, which can be inserted into a common lock cylinder structure to unlock the lock. This dual unlocking method design ensures both convenience in daily use and rapid response in emergency situations.

[0081] Thirdly, regarding the adjustment and locking part of the fastening collar 2, as a preferred embodiment, the fastening control member includes a control member and a rotating gear 7. The rotating gear 7 is rotatably arranged in the smart lock assembly 1. A sawtooth bar 22 is provided on the connecting belt 21. The rotating gear 7 is driven by the sawtooth bar 22 and meshed with the connecting belt 21. The control member is in transmission connection with the rotating gear 7 to control the rotation of the rotating gear 7. Figure 3 As shown, the rotation of the rotating gear 7 corresponds to the degree of engagement of the connecting belt 21, thereby adjusting the inner diameter of the formed fastening collar 2. Regarding the locking portion, for the application of the rotating gear 7, a micromotor and a limiter can be provided on the fastening control component. The control chip controls the movement of the limiter via the micromotor. When locking, the limiter abuts against the tooth surface of the rotating gear 7, forming a bidirectional locking structure similar to a ratchet pawl. Similarly, the lock core structure can be connected to another limiter. When the mechanical key is inserted into the lock core and rotated, it can correspondingly control the rotation of the limiter to achieve locking.

[0082] Furthermore, in this embodiment, Figure 2 and Figure 4 As shown, the limiting device also includes at least two limiting seats 8. The limiting seats 8 are provided with mounting holes 13, and the limiting seats 8 are mounted on the connecting belt 21 through the mounting holes 13. The limiting seats 8 are locked to the end of the locking rod 3 away from the movable clamp 4. The limiting seats 8 are provided with a rotating wheel 10 that is positioned within the mounting holes 13. The rotating wheel 10 is meshed with a serrated bar 22. The limiting seats 8 are mounted on the connecting belt 21 through the cooperation of the rotating wheel 10 and the serrated bar 22. The limiting seats 8 can be flexibly adjusted relative to the connecting belt 21 according to actual needs to ensure a locked connection with the locking rod 3.

[0083] Reference Figure 2 As shown, both the stopper 8 and the smart lock assembly 1 are located on the same plane as the fastening collar 2. Specifically, the stopper 8 may be provided with an annular lock 11 having a through hole. During use, the end of the locking rod 3, away from the movable clamp 4, is passed through the through hole and tightened by the annular lock 11. Similar to the smart lock assembly 1, the annular lock 11 on the stopper 8 may also integrate a control chip to implement intelligent lock opening and closing, thereby improving the automation level of the lock. Furthermore, the locking rod 3 may be provided with a recessed portion 15 around the rod body to engage with the lock tongue of the annular lock 11.

[0084] In addition, in this embodiment, Figure 6As shown, the movable clamp 4 includes a first clamp arm 41, a second clamp arm 42, and a tightening spring 43. The first clamp arm 41 and the second clamp arm 42 are arranged parallel to each other on the locking rod 3, and the second clamp arm 42 can slide on the locking rod 3 toward or away from the first clamp arm 41. The tightening spring 43 is arranged between the first clamp arm 41 and the second clamp arm 42, and the ends of the tightening spring 43 are respectively connected to the first clamp arm 41 and the second clamp arm 42. The spacing between the first clamp arm 41 and the second clamp arm 42 can be adjusted to flexibly accommodate valve handles 6 of different sizes. In addition, adjusting the spacing simultaneously stretches the tightening spring 43, and the contraction force of the stretched tightening spring 43 achieves clamping.
