Description

Technical Field

[0001] This utility model relates to the field of lead seal processing technology, and in particular to a lead seal sealing device. Background Technology

[0002] In various applications such as electricity metering, oil tanker transportation, energy management, and customs supervision, lead seals are typically used for physical sealing of critical facilities and equipment to prevent unauthorized opening, tampering, or theft. Lead seals play a crucial role in maintaining system integrity and security. Traditional lead sealing operations are mostly carried out manually with clamps or using simple mechanical tools, which is not only inefficient but also suffers from uneven sealing force and uncontrollable sealing quality, posing potential management risks. With the rapid development of automation and intelligent technologies, higher demands are placed on the accuracy, safety, and visual operation of sealing operations, necessitating structural optimization and functional enhancement of lead seal sealing devices.

[0003] Existing lead seal sealing equipment still suffers from several drawbacks during operation. Many devices cannot precisely control the sealing force during pressure sealing, leading to incomplete seals or even seal breakage. Furthermore, the lack of real-time feedback and observation mechanisms makes it difficult for users to assess the sealing status promptly, posing risks of overpressure or misoperation. Some designs also lack adjustable buffers when the actuator operates, resulting in a lack of flexible control during the sealing process, increased equipment wear, and even potential safety accidents. Therefore, we provide a lead seal sealing device. Utility Model Content

[0022] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0023] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0024] Example 1, such as Figure 1-3 As shown, this utility model provides a technical solution: a lead seal sealing device, including: a working mechanism 1, the working mechanism 1 including a placement plate 11, a support frame 12 is provided at the bottom of the placement plate 11, an operation box 13 is provided on one side of the placement plate 11, a controller 14 is provided on the operation box 13, a transport frame 16 is provided on the placement plate 11, a placement frame 15 is provided on the connecting frame of the four support frames 12, a transport motor 17 is provided at one end of the transport frame 16, a transporter 18 is provided on the transport frame 16, and a protective mechanism 2 is provided on the placement plate 11;

[0025] The protective mechanism 2 includes a support frame 21, a protective frame 22 is provided in the support frame 21, a protective plate 23 is provided at one end of the protective frame 22, and a protective net 24 is provided in the protective frame 22.

[0026] One end of the support frame 12 is cast into the bottom of the placement plate 11, one end of the operation box 13 is welded to one side of the placement plate 11, one end of the controller 14 is connected to the operation box 13, and the transport frame 16 is installed on the placement plate 11.

[0027] The transport frame 16 is installed on the placement plate 11, one end of the transport motor 17 is connected to the transport frame 16, the transporter 18 is limited on the transport frame 16 for sliding adjustment, the bottom of the support frame 21 is welded to the placement plate 11, and the placement frame 15 is placed on the connecting frame of the four support frames 12.

[0028] Three protective frames 22 are installed around the support frame 21, two protective plates 23 are installed at one end of the protective frame 22 respectively, and the outer surface of the protective net 24 is nested in the protective frame 22.

[0029] In this embodiment, when using this lead seal sealing device to seal a lead seal, the operator can place the lead seal to be sealed on the transporter 18 and then control the controller 14 to start the transport motor 17. The transport motor 17 will then drive the transporter 18 to transport the lead seal to be sealed on the transport frame 16. When it is transported to the designated position, it will be processed and sealed. The protective mechanism 2 on the placement plate 11 can make the sealing process safer during actual use.

[0030] Example 2, as follows Figure 1-4 As shown, a sealing mechanism 3 is provided on one side of the transport frame 16 on the placement plate 11. The sealing mechanism 3 includes a mounting frame 31, a hydraulic device 32 is provided on the mounting frame 31, a hydraulic push plate 33 is provided at one end of the hydraulic device 32, a balance bar 34 is provided on one side of both ends of the hydraulic push plate 33, a telescopic spring 35 is provided at the bottom of the hydraulic push plate 33, and a hydraulic plate 36 is provided at the end of the telescopic spring 35 away from the hydraulic push plate 33.

[0031] One end of the mounting bracket 31 is welded and cast onto the placement plate 11. The hydraulic device 32 is connected to the mounting bracket 31. One end of the hydraulic device 32 passes through the mounting bracket 31 and is connected to the hydraulic push plate 33. One end of the balance bar 34 is connected to the hydraulic push plate 33. The outer surface of the balance bar 34 is nested in the mounting bracket 31 for lifting and lowering adjustment. The two ends of the telescopic spring 35 are respectively connected between the hydraulic push plate 33 and the hydraulic plate 36 for protection and adjustment.

[0032] In this embodiment, after the lead seal is transported to the sealing mechanism 3 via the conveyor 18, the operator can control the control box 13 to start the hydraulic actuator 32 by controlling the controller 14. This allows the hydraulic actuator 32 to pass through the mounting frame 31 and push the hydraulic push plate 33. During the pushing process, the balance bar 34 will rise and fall with the hydraulic push plate 33. When the hydraulic plate 36 contacts the lead seal, the extension spring 35 will compress it as the hydraulic push plate 33 moves forward. The lead seal will only be sealed when it is compressed to the maximum. During the compression process, the operator can observe more closely and stop the compression at any time, which further improves its practicality in actual use.

[0033] Working principle:

[0034] like Figure 1-4 As shown, when using this lead seal sealing device for lead seal sealing operations, the operator only needs to accurately place the lead seal to be sealed on the conveyor 18. Subsequently, a start command is issued through the operation controller 14, and the operation box 13 can drive the transport motor 17 to start working. Driven by the transport motor 17, the conveyor 18 moves smoothly along the track of the transport frame 16, transporting the lead seal to the designated processing and sealing position.

[0035] During this process, the protective mechanism 2 installed on the placement plate 11 can effectively prevent external factors from interfering with the sealing operation, thereby improving the safety and stability of the entire sealing process.

[0036] After the lead seal is delivered into the sealing mechanism 3 via the conveyor 18, the operator again issues a command through the controller 14, instructing the control box 13 to activate the hydraulic actuator 32. The action of the hydraulic actuator 32 drives it through the mounting bracket 31, applying a thrust to the hydraulic push plate 33. During the forward movement of the hydraulic push plate 33, the balance bar 34 rises and falls synchronously with the push plate, thereby ensuring uniform force distribution and avoiding unnecessary displacement or damage to the lead seal.

[0037] When the hydraulic plate 36 contacts the lead seal surface, the telescopic spring 35 is gradually compressed as the hydraulic push plate 33 advances. Only when the spring is fully compressed to its limit will the hydraulic plate 36 apply sufficient pressure to the lead seal to complete the final sealing action. The entire compression and sealing process is gradual and controllable, allowing operators to observe the sealing status at any time and stop the compression operation when necessary, greatly enhancing the flexibility and practicality of the device in actual applications.
