Description

Technical Field

[0001] This utility model belongs to the field of hydraulic cylinder technology, specifically relating to a novel anti-electrical cylinder. Background Technology

[0002] In the electrolysis industry, processes such as extraction and refining of various metals and other substances are achieved through electrochemical reactions. The conductivity of the equipment is subject to strict requirements. Among these processes, hydraulic cylinders, as common equipment, play an important role in performing operations such as material conveying and pressure application.

[0003] However, most existing hydraulic cylinders are made of metal, which makes them conductive. But the electrolysis industry cannot allow equipment to have conductive properties. To achieve the anti-conductive function of the hydraulic cylinder, it is generally achieved by coating it with insulating material to make the cylinder non-conductive, or by adding insulating plates at the connection of the mechanism. However, these methods may have problems such as easy wear of the coating and insufficient reliability of the connection of the insulating plate, which affect the stability and insulation reliability of the hydraulic cylinder. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a new type of anti-conductive hydraulic cylinder to solve the problems of insufficient stability and insulation reliability of the existing anti-conductive hydraulic cylinder.

[0005] One aspect of this utility model provides a novel anti-conductive hydraulic cylinder, comprising a cylinder body, a piston assembly, an insulating assembly, and a connecting assembly. The piston assembly is installed inside the cylinder body, and the connecting assembly is installed on the piston assembly. The connecting assembly is used to connect the cylinder body to an external device.

[0010] In one embodiment, the piston assembly includes a piston and a piston rod, the piston rod being movably connected in the inner cylinder, the piston being mounted on the piston rod, and the connecting assembly being mounted on the piston rod.

[0017] Beneficial effects:

[0018] Compared with the prior art, this utility model provides a novel anti-electrical conductivity hydraulic cylinder, which has the following beneficial effects:

[0019] This invention effectively prevents current conduction on the cylinder body by isolating the outer shell with a first insulating component, reducing the risk of abnormal current paths forming inside the cylinder.

[0028] Please refer to Figure 1-3 One embodiment of this utility model provides a novel anti-conductive hydraulic cylinder, including a cylinder body 1, a piston assembly 2, an insulation assembly 3, and a connecting assembly 4. The piston assembly 2 is installed inside the cylinder body 1, and the connecting assembly 4 is installed on the piston assembly 2. The connecting assembly 4 is used to connect the cylinder body 1 to an external device.

[0029] The insulating component 3 includes a first insulating element 31 and a second insulating element 32. The first insulating element 31 is mounted on the cylinder body 1, and the second insulating element 32 is mounted on the connecting component 4.

[0030] The first insulating member 31 is used to isolate the cylinder body 1 to prevent current from being conducted on the cylinder body 1, and the second insulating member 32 is used to prevent current from being conducted between the cylinder body 1 and external equipment.

[0031] In this solution, the first insulating component 31 isolates the outer shell 11, effectively preventing current from being conducted on the cylinder body 1 and reducing the risk of current forming an abnormal path inside the cylinder. By installing the second insulating component 32 on the connection part 432 of the connecting assembly 4, and using the second insulating component 32 to isolate the current conduction between the external equipment and the connecting assembly 4, the current from the external equipment is prevented from being conducted to the connecting assembly 4, thereby preventing the current from being conducted between the cylinder body 1 and the external equipment, thus improving the overall equipment's anti-conduction stability and insulation reliability.

[0032] In one embodiment, the cylinder body 1 includes an outer shell 11 and an inner cylinder 12, and the piston assembly 2 is installed in the inner cylinder 12.

[0033] In one embodiment, the first insulating member 31 separates the outer casing 11 from the inner cylinder 12.

[0034] In this solution, the outer casing 11 is directly isolated by the first insulating component 31, which can directly block the possible current conduction path inside the cylinder body 1. Compared with the traditional coating method, the insulation effect of this installation method is more stable and durable, effectively avoiding the problem of insulation performance degradation due to coating wear, fundamentally improving the insulation reliability of the cylinder body 1, and ensuring the anti-conductive performance of the cylinder during long-term use.

[0035] In one embodiment, the piston assembly 2 includes a piston 21 and a piston rod 22, the piston rod 22 being movably connected in the inner cylinder 12, the piston 21 being mounted on the piston rod 22, and the connecting assembly 4 being mounted on the piston rod 22.

[0036] In one embodiment, the connecting assembly 4 includes a mounting member 41, a fixing member 42, and a connecting member 43, wherein the connecting member 43 is mounted on the mounting member 41, and the mounting member 41 is mounted on the piston rod 22 via the fixing member 42;

[0037] In one embodiment, the mounting member 41 has an insertion hole 411, and the fixing member 42 is installed in the insertion hole 411. The fixing member 42 is used to fasten the mounting member 41 and the piston rod 22.

[0038] In one embodiment, the piston rod 22 has an external thread (not shown) at one end near the mounting member 41, and the mounting member 41 has an internal thread (not shown) at one end near the piston rod 22, with the external thread (not shown) adapted to the internal thread (not shown).

[0039] It should be noted that the fastener 42 can be a pin. In the actual assembly process, the workers can first connect the mounting part 41 to the piston rod 22 by external thread (not shown) and internal thread (not shown), and then fasten the connection between the mounting part 41 and the piston rod 22 by inserting the pin into the insertion hole 411.

[0040] In this solution, the cooperation between the insertion hole 411 and the fixing member 42 further enhances the connection stability between the mounting member 41 and the piston rod 22, so that even if the cylinder is subjected to external forces such as vibration and impact, it can still be stably connected and work normally, thereby maintaining the overall stability of the cylinder. In addition, it also ensures the normal working conditions of the second insulating member 32, ensuring that its insulation performance is not affected by the instability of the connection part 432.

[0041] In one embodiment, the connector 43 includes a support portion 431 and a connecting portion 432, the support portion 431 being mounted on the mounting member 41, and the second insulating member 32 being mounted on the connecting portion 432.

[0042] In one embodiment, an end cap 5 is installed on one end of the outer casing 11 near the connecting assembly 4.

[0043] In one embodiment, both the first insulating member 31 and the second insulating member 32 are made of nylon.

[0044] In this solution, nylon material has excellent insulation and mechanical properties. Using nylon material to make insulating parts not only ensures good insulation effect and effectively prevents current conduction, but also, due to its good mechanical properties, is not easily damaged during long-term use. This eliminates the need for daily maintenance of coatings and insulating boards, avoiding the problem that the lack of daily maintenance may affect the stability of the anti-conductive hydraulic cylinder, and greatly improving the stability and reliability of the insulation effect.

[0045] The complete assembly process of this utility model is described below:

[0046] First, the operator fixes the piston 21 to the output end of the piston rod 22, then installs the assembled piston rod 22 into the inner cylinder 12 of the cylinder body 1, then installs the end cap 5 onto the outer shell 11 at the end away from the output end of the piston rod 22, then fixes the mounting piece 41 to the output end of the piston rod 22 through external threads (not shown) and internal threads (not shown), then inserts the pin into the insertion hole 411 on the mounting piece 41, and finally installs the first insulating piece 31 at the partition of the outer shell 11 and the second insulating piece 32 at the connecting part 432 of the mounting piece 41.

[0047] Beneficial effects:

[0048] Compared with the prior art, this utility model provides a novel anti-electrical conductivity hydraulic cylinder, which has the following beneficial effects:

[0049] This invention effectively prevents current from being conducted on the cylinder body 1 by isolating the outer shell 11 with the first insulating component 31, reducing the risk of abnormal current paths forming inside the cylinder. Compared with the traditional method of relying solely on coatings, this design, which directly isolates the structure, provides more stable and durable insulation, improving overall insulation reliability. Furthermore, by installing the second insulating component 32 on the connection portion 432 of the connecting assembly 4, this invention isolates the current conduction between external equipment and the connecting assembly 4, preventing current from being conducted to the connecting assembly 4 and thus preventing current conduction between the cylinder body 1 and the external equipment. This avoids current leakage caused by the connection portion 432, improving overall insulation reliability. Additionally, this invention eliminates the need for routine maintenance of the coating and insulating plate, preventing potential issues affecting the stability of the anti-conductive cylinder due to lack of routine maintenance.
