Description
Technical Field
[0001] This utility model belongs to the field of power technology, specifically an insulator cotter pin installation device. Background Technology
[0002] In the construction and operation and maintenance of power transmission lines, insulators are key components that ensure the insulation performance and structural stability of the lines. They need to be assembled and fixed in multiple units through specific connection devices. The insulator cotter pin installation device is the core component used to complete the connection of adjacent insulators.
[0003] Currently, most existing insulator connection devices rely on fasteners such as bolts and nuts for connection. During installation, workers need to carry special tools such as wrenches. In high-altitude operation scenarios, not only are the tools inconvenient to carry, but the fasteners also need to be tightened repeatedly to ensure a stable connection. The operation process is cumbersome and time-consuming. Utility Model Content
[0004] The purpose of this invention is to provide an insulator cotter pin installation device to solve the problems of cumbersome and time-consuming operation procedures in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulator cotter pin installation device, comprising a latch, a connecting rod, and a fixing rod; an insulator structure is provided around the fixing rod, and connecting rods are fixedly connected to both ends of the fixing rod; a pin is movably installed on the top of the connecting rod; a latch is movably installed inside the connecting rod, and a socket is provided inside the latch, with the pin engaging with the socket.
[0006] Preferably, the connecting rod has a movable groove inside, and the movable groove is adapted to the latch.
[0007] Preferably, the top and bottom of the latch are fixedly connected to shafts, and the shafts are engaged with the connecting rods.
[0008] Preferably, the top of the pin is provided with a pull ring, and the pull ring is provided with a groove inside.
[0009] Preferably, a buffer pad is provided between the inner wall of the insulator structure and the outer wall of the fixing rod, and the buffer pad is made of aging-resistant rubber material.
[0010] Preferably, the outer surface of the latch is coated with a zinc-chromium coating.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This utility model, through the design of a locking buckle rotating around the shaft and the engagement and limiting mechanism of the pin and the insertion hole, allows for rigid limitation of the buckle angle during insulator installation by manually completing the connecting rod docking, buckle pressing and rotating, and pin insertion operations, effectively preventing the buckle from springing back and loosening. At the same time, the concave-convex engagement structure of adjacent buckles restricts buckle displacement in the axial direction, preventing the insulator structure from detaching along the axis of the fixed rod. The entire installation process does not require additional tools, greatly simplifying the operation process, reducing manpower input and on-site operation time, and significantly improving the work efficiency of insulator installation. It is especially suitable for power field scenarios with high requirements for installation convenience and timeliness.
[0013] 2. This utility model optimizes the connection and disassembly structure of the insulator. During disassembly, simply pulling the pin upwards releases the angle limitation on the latch, and then pulling the insulator structure at both ends quickly releases the latch engagement state, achieving convenient disassembly of the insulator. This solves the problems of complex operation and long time consumption in the traditional insulator assembly and disassembly process. In addition, the overall structural design takes into account both connection stability and operation convenience. It ensures the structural reliability of the insulator after installation through multiple limiting mechanisms, and lowers the operation threshold through manual operation design, allowing workers to efficiently complete the assembly and disassembly operations without professional tools. This further enhances the practicality and applicability of the device in power maintenance, repair and other scenarios. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] As attached Figure 1 To be continued Figure 4 As shown:
[0023] Example 1: This utility model provides an insulator cotter pin installation device, including a locking buckle 3, a connecting rod 4, and a fixing rod 5; an insulator structure 1 is provided on the periphery of the fixing rod 5, and the connecting rod 4 is fixedly connected to both ends of the fixing rod 5. A pin 2 is movably installed on the top of the connecting rod 4; a locking buckle 3 is movably installed inside the connecting rod 4, and an insertion hole 302 is provided inside the locking buckle 3, with the pin 2 engaging with the insertion hole 302.
[0024] During insulator installation, workers first align the connecting rods 4 of two adjacent insulator structures 1. During this alignment process, the latches 3 on each side of the insulator structure 1 come into contact with each other due to the approaching connecting rods 4, generating a squeezing force. This force drives the latches 3 to rotate around the shaft 301 connected to the connecting rod 4. When the latches 3 rotate to the preset alignment position, workers can operate the pin 2 at the top of the connecting rod 4, inserting it downwards along the movable installation path of the connecting rod 4 into the insertion hole 302 inside the latch 3. The interlocking structure of the pin 2 and the socket 302 can directly and rigidly limit the rotation angle of the latch 3, effectively preventing the latch 3 from springing back and loosening after the squeezing force disappears. This initially fixes the relative position of the adjacent insulator structures 1, laying the foundation for subsequent stable connection. At the same time, the adjacent latches 3 of this device are designed with a concave-convex interlocking structure. After the latch 3 is rotated into place, the concave and convex parts of the latches 3 on both sides will automatically interlock with each other. This structure can limit the relative displacement of the two latches 3 in the axial direction, preventing the adjacent insulator structures 1 from separating along the axis of the fixing rod 5, further enhancing the connection stability. The entire installation process does not require additional tools. The insulator structures 1 can be quickly connected by simply manually connecting, squeezing and rotating, and inserting the pin 2, greatly reducing manpower input and operation time, and significantly improving the efficiency of on-site installation work.
[0025] During disassembly, workers only need to pull the pin 2 upwards to release its restriction on the angle of the latch 3, and then pull the adjacent insulator structures 1 to both ends respectively. The locking state of the latch 3 can be released, realizing the rapid disassembly of the insulator structure 1. The ease of operation and installation efficiency are well matched.
[0026] In one embodiment of this utility model, the connecting rod 4 is provided with a movable groove 401 inside, and the movable groove 401 is adapted to the latch 3.
[0027] The locking buckle 3 can slide precisely along the trajectory of the movable groove 401, preventing the locking buckle 3 from shifting or getting stuck inside the connecting rod 4, ensuring that the locking buckle 3 can be smoothly adjusted to align with the pin 2. When it is necessary to fix the locking buckle 3, the movable groove 401 acts as a limit for the locking buckle 3, preventing the locking buckle 3 from shifting due to external force during the operation of the device, ensuring the engagement stability of the pin 2 and the insertion hole 302 on the locking buckle 3, thereby improving the structural reliability of the entire insulator cotter pin installation device.
[0028] In one embodiment of the present invention, the top and bottom of the latch 3 are fixedly connected with shafts 301, and the shafts 301 are engaged with the connecting rods 4.
[0029] The latch 3 can rotate flexibly around the shaft 301, allowing the insertion hole 302 on the latch 3 to be quickly and accurately aligned with the pin 2. At the same time, the engagement relationship between the shaft 301 and the connecting rod 4 restricts the displacement of the latch 3 in the direction perpendicular to the axis of the shaft 301, preventing the latch 3 from falling off or shifting, and further optimizing the ease of assembly and structural stability of the device.
[0030] In one embodiment of the present invention, a pull ring is provided at the top of the pin 2, and a groove is provided inside the pull ring.
[0031] When installing pin 2, the operator can move pin 2 by pulling the pull ring without directly contacting the main body of pin 2, reducing the difficulty of operation. Especially in scenarios where space is limited or where it is difficult to exert force directly by hand, the pull ring provides a more convenient point of application. When removing pin 2, simply pull the pull ring to pull pin 2 out of the socket 302. Compared to a design without a pull ring, this significantly improves the efficiency of installing and removing pin 2 and reduces operation time.
[0032] Working principle: The operator first aligns the connecting rods 4 of adjacent insulator structures 1. During the alignment process, the latches 3 of the two insulator structures 1 rotate around the shaft 301 due to mutual contact and compression. After the latches 3 rotate to the preset alignment position, the pin 2 at the top of the connecting rod 4 is operated and inserted downward into the insertion hole 302 inside the latch 3. The engagement of the pin 2 and the insertion hole 302 limits the angle of the latch 3, preventing the latch 3 from springing back and loosening. At the same time, the concave and convex engagement structures of the adjacent latches 3 automatically engage with each other, restricting the displacement of the latches 3 in the axial direction and preventing the adjacent insulator structures 1 from separating along the axis of the fixed rod 5, thus achieving a quick connection of the insulator structures 1.
[0033] Example 2: This example is basically the same as the previous example, except that a buffer pad is provided between the inner wall of the insulator structure 1 and the outer wall of the fixing rod 5, and the buffer pad is made of aging-resistant rubber material.
[0034] When subjected to external vibrations or impacts, the buffer gasket utilizes the elastic deformation properties of its rubber material to absorb the collision force and vibration energy between the insulator structure 1 and the fixed rod 5, preventing wear or damage caused by rigid contact. Simultaneously, the aging-resistant rubber material effectively resists environmental erosion such as ultraviolet radiation, high temperatures, and humidity changes, extending the gasket's service life.
[0035] In one embodiment of this utility model, the outer surface of the latch 3 is coated with a zinc-chromium coating.
[0036] The zinc-chromium coating exhibits excellent corrosion resistance, forming a dense protective film on the surface of the latch 3. This film isolates the latch 3 from air, moisture, dust, and corrosive media that may be present in the operating environment of electrical equipment, preventing rust. Even with prolonged outdoor or harsh environments, it effectively extends the service life of the latch 3.
[0037] Working principle: The aging-resistant rubber buffer pad between the inner wall of the insulator structure 1 and the outer wall of the fixing rod 5 can absorb the collision force and vibration energy between the two through elastic deformation, avoiding wear or damage caused by rigid contact, and can resist the corrosion of external environment such as ultraviolet rays, high temperature, and humidity changes to extend service life. The zinc chromium coating on the outer surface of the latch 3 forms a dense protective film, which isolates air, moisture, dust and corrosive media from contact with the latch 3 body, preventing the latch 3 from rusting and extending its service life.
[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
