Description

Technical Field

[0001] This invention relates to the field of power distribution network technology, and in particular to an installation device for a moving cotter pin in a power distribution network. Background Technology

[0002] The construction of a power distribution network refers to the establishment of power distribution facilities that can receive electrical energy from the transmission network or local power plants. For example, high-voltage power grids and circuits in everyday houses are power distribution facilities. Power distribution facilities distribute power locally or distribute it to various users in stages according to voltage.

[0003] Distribution networks are characterized by multiple voltage levels, complex network structures, diverse types, numerous and widespread work sites, and relatively harsh installation environments, resulting in a relatively large number of safety risks. During network movement, there is a risk of cotter pins on cable connectors becoming detached or missing, requiring specialized distribution tools for replacement. These tools have long poles to allow technicians to perform the replacement operation from the ground or a relatively safe location. To hold the cotter pin, a pliers-like clamp is installed at the end of the long pole. A connecting wire is attached to the movable end of the clamp, and a spring connects the movable ends. Pulling the connecting wire clamps the cotter pin. After the cotter pin is installed on the cable connector, the connecting wire is released, causing the clamp to release the cotter pin. The clamp then pushes the cotter pin open, allowing it to enter the connector hole of the cable connector. However, because the technician's position is lower than that of the cable connector, they have a poor viewing angle, making it difficult to align the cotter pin when opening it. This can easily lead to hitting the wrong spot or damaging other components, and also knocking the cotter pin off, requiring the technician to re-pin it, increasing the time spent on this task. Furthermore, being at a higher position poses certain personal safety risks for the technician. Summary of the Invention

[0050] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0053] Example 1

[0054] like Figure 1 As shown, this embodiment provides an installation device for a moving cotter pin in a power distribution network. The installation device includes a rod assembly 1, a fixed housing 3, a clamping assembly 4, a pushing member 5, a transmission assembly 6, and a drive assembly 7. One end of the rod assembly 1 is provided with a connecting frame 2, and the fixed housing 3 is connected to the connecting frame 2. The clamping assembly 4 has a clamping end and a movable end. The clamping end is located outside the fixed housing 3 and is used to clamp the cotter pin, while the movable end is located inside the fixed housing 3. The pushing member 5 is located outside the fixed housing 3 and is used to push the cotter pin against the cable connector. The transmission assembly 6 is located inside the fixed housing 3 and is a transmission connection between the pushing member 5 and the movable end of the clamping assembly 4. The first end of the drive assembly 7 is connected to the transmission assembly 6, and the second end of the drive assembly 7 is movably connected to the rod assembly 1. The drive assembly 7 is used to, via the transmission assembly 6, cause the clamping assembly 4 to clamp the cotter pin and the pushing member 5 to move away from the clamping end of the clamping assembly 4, or to cause the clamping assembly 4 to release the cotter pin and the pushing member 5 to push the cotter pin against the cable connector.

[0055] The cotter pin installation device for power distribution networks provided in this embodiment has a rod assembly 1 that can be held by a technician. The operating drive assembly 7 can cause the clamping end of the clamping assembly 4 to clamp the cotter pin, while the pushing member 5 moves away from the clamping end of the clamping assembly 4, or the clamping assembly 4 can release the cotter pin and the pushing member 5 can push the cotter pin against the cable connector, so that the cotter pin is effectively installed on the cable connector. This solves the problem in the prior art that when technicians knock off the cotter pin, it is difficult to align the cotter pin, and it is easy to knock the wrong position and hit other parts, causing damage to other parts. It is also easy to knock the cotter pin off, requiring technicians to re-pin it. The installation device provided in this embodiment can conveniently and quickly install the cotter pin on the cable connector, shorten the cotter pin installation time, improve the efficiency of cotter pin installation, and reduce the operation risk of technicians.

[0056] In some embodiments, such as Figure 2 As shown, the rod assembly 1 includes a connecting rod 12 and a gripping rod 13. One end of the connecting rod 12 is provided with a connecting bracket 2, and the other end of the connecting rod 12 is threadedly connected to the gripping rod 13, which is for the operator to hold. The rod assembly 1 is designed to be detachable for easy carrying. When using the mounting device, the gripping rod 13 is then mounted on the connecting rod 12.

[0057] To prevent technicians from slipping when holding the grip lever 13, an anti-slip sleeve is provided on the outer periphery of the grip lever 13. The anti-slip sleeve can be a rubber sleeve or a plastic sleeve, and the outer wall of the rubber sleeve or plastic sleeve has anti-slip protrusions.

[0058] The connecting frame 2 has a U-shaped structure. Each of the opposite side walls of the connecting frame 2 has an arc-shaped adjustment groove 21. A portion of the fixing shell 3 is positioned between the opposite side walls of the connecting frame 2, and each of the opposite sides of the fixing shell 3 has a threaded post 31. The threaded post 31 passes through the adjustment groove 21 and is screwed with a nut, allowing it to slide along the adjustment groove 21. When the fixing shell 3 needs to be fixed, the nut is tightened, pressing against the side wall of the connecting frame 2. The opposite side walls of the connecting frame 2 then compress the fixing shell 3, thus fixing its position. When the angle of the fixing shell 3 needs to be adjusted, the nut is loosened, and the fixing shell 3 is rotated, thereby adjusting the angle of the clamping end of the clamping assembly 4. This allows technicians to quickly and accurately install the cotter pin onto the cable connector. Furthermore, the installation device provided in this embodiment can also be used to close switches at high points on the power grid. The position of the fixing shell 3 can be adjusted to increase the overall length of the installation device. By pushing the switch through the fixing shell 3, the installation device can be made multifunctional.

[0059] In some embodiments, such as Figure 3 and Figure 4As shown, the fixed shell 3 includes two opposing side plates 32 and a connecting plate 33 connecting the two side plates 32. The connecting plate 33 connects the partial edges of the two side plates 32, and the two side plates 32 and the connecting plate 33 enclose a receiving cavity with an opening. The transmission assembly 6 is placed in the receiving cavity.

[0060] like Figure 4 , Figure 5 and Figure 6 As shown, the clamping assembly 4 includes two symmetrically arranged linkage frames 41. One end of the linkage frame 41 is provided with a clamping block 42, and the two clamping blocks 42 form a clamping end. The other end of the linkage frame 41 is a movable end, and the other end of the linkage frame 41 is connected to the drive assembly 7.

[0061] Optionally, the linkage frame 41 includes a first linkage rod 411, a second linkage rod 412, and a third linkage rod 413 connected in sequence. The first linkage rod 411 is perpendicularly connected to the second linkage rod 412, and the third linkage rod 413 forms an obtuse angle with the second linkage rod 412. The first linkage rod 411 is eccentrically connected to the gear disk 61, and the third linkage rod 413 is connected to a clamping block 42. The clamping block 42 increases the contact area with the cotter pin, preventing it from slipping out when clamped. Furthermore, the surface of the clamping block 42 that clamps the cotter pin is provided as an anti-slip surface to increase the contact friction with the cotter pin.

[0062] The transmission assembly 6 includes two gear discs 61, a moving rod 62, and a resetting member 63. Each gear disc 61 has a first meshing tooth 64 on a circumferential portion. The moving rod 62 has a second meshing tooth 65 on each opposite side of the first meshing tooth 64. The other end of the linkage frame 41 is eccentrically connected to the corresponding gear disc 61. The end of the moving rod 62 away from the clamping end of the clamping assembly 4 is connected to the drive assembly 7, and the end of the moving rod 62 near the clamping end of the clamping assembly 4 is connected to the pusher 5. The resetting member 63 connects the moving rod 62 and the retaining housing 3, and has a tendency to move the moving rod 62 toward the clamping end of the clamping assembly 4. The drive assembly 7 drives the moving rod 62 to move, causing the two gear discs 61 to rotate in opposite directions, thereby actuating the two linkage frames 41 and causing the clamping end of the clamping assembly 4 to clamp the cotter pin. When the drive assembly 7 does not drive the moving rod 62 to move, that is, when no force is applied to the moving rod 62, the reset member 63 resets the moving rod 62, thereby driving the two gear disks 61 to rotate in opposite directions, thereby driving the two linkage frames 41 to move, and causing the clamping end of the clamping assembly 4 to release the cotter pin. The moving rod 62 drives the pushing member 5 to move toward the clamping end of the clamping assembly 4 and pushes the cotter pin against the cable connector, thereby realizing the installation of the cotter pin.

[0063] The first linkage rod 411 of the linkage frame 41 is eccentrically connected to the gear disk 61. The opening of the aforementioned fixed shell 3 provides clearance space for the linkage frame 41 to rotate with the gear disk 61, so that the clamping end of the clamping assembly 4 can clamp or release the cotter pin.

[0064] Optionally, the transmission assembly 6 further includes a support rod 66, with connecting posts 67 perpendicularly positioned at both ends. Each connecting post 67 is rotatably connected to the center of a gear disk 61, and the connecting post 67 is fixedly connected to the fixed housing 3. Specifically, one end of the connecting post 67 passes through the center of the gear disk 61 and connects to the side plate 32 of the fixed housing 3. The support rod 66 fixes the gear disk 61 to the fixed housing 3, and the gear disk 61 can rotate relative to the connecting post 67.

[0065] The fixed housing 3 is provided with a support frame 68, which has a sliding groove. One end of the moving rod 62 passes through the groove wall and is slidably mounted on the support frame 68. One end of the moving rod 62 is connected to the pusher 5, and the other end of the moving rod 62 passes through the connecting plate 33 of the fixed housing 3, is placed on the outside of the fixed housing 3, and is connected to the drive assembly 7.

[0066] The support frame 68 is fixedly connected to the inner wall of the fixed shell 3. The reset member 63 is sleeved on the moving rod 62, with one end connected to the moving rod 62 and the other end abutting against the side wall of the sliding groove. The reset member 63 is a spring, which accumulates elastic potential energy when the clamping end of the clamping assembly 4 clamps the cotter pin. When the driving assembly 7 does not apply force to the moving rod 62, the reset member 63 releases its elastic potential energy, causing the moving rod 62 to reset and driving the pushing member 5 to push the cotter pin against the cable connector, thus realizing the installation of the cotter pin.

[0067] In some embodiments, refer to Figure 2 and Figure 7As shown, the drive assembly 7 includes a rotating sleeve 71, a cable 73, and pulleys 74. The rotating sleeve 71 is fitted onto the rod assembly 1, which has an L-shaped groove 11. The groove 11 is specifically located on the grip rod 13, with the portion of the groove 11 extending circumferentially from the connecting frame 2. The rotating sleeve 71 has a sliding block 72, which is disposed within the groove 11. One end of the cable 73 is connected to the rotating sleeve 71, and the other end is connected to the transmission assembly 6. Multiple pulleys 74 are provided, with pulleys 74 respectively on the fixed housing 3 and the connecting frame 2, and the cable 73 abuts against the pulleys 74. Pulling the rotating sleeve 71 along the axial direction of the rod assembly 1 causes the sliding block 72 to slide within the slide groove 11. When the sliding block 72 slides to the corner position of the slide groove 11, the clamping end of the clamping assembly 4 is in the state of clamping the cotter pin. In order to prevent the rotating sleeve 71 from being reset under the action of the reset member 63, the clamping end of the clamping assembly 4 releases the cotter pin, rotates the rotating sleeve 71, and places the sliding block 72 within the portion of the slide groove 11 that extends circumferentially along the rod assembly 1, thereby limiting the rotation sleeve 71.

[0068] like Figure 8 and Figure 9 As shown, the rotating sleeve 71 includes a rotating sleeve body 711 and a rotating ring 712 rotatably disposed at one end of the rotating sleeve body 711. A sliding block 72 is disposed on the inner sidewall of the rotating ring 712. When the sliding block 72 slides into or out of the portion of the slide groove 11 that extends circumferentially along the rod assembly 1, the rotating ring 712 can be rotated without rotating the entire rotating sleeve 71, and the position of the cable 73 will not change.

[0069] Optionally, one end of the rotating ring 712 is provided with a plug-in block, and one end face of the rotating sleeve body 711 is recessed with a plug-in groove, and the plug-in block is slidably disposed in the plug-in groove.

[0070] Combination Figure 2 and Figure 10 As shown, the cable 73 can be configured into multiple sections for easy carrying. Multiple cables 73 are assembled during use. For example, the cable 73 includes a first cable 731, a second cable 732, and a third cable 733. The two ends of the second cable 732 are detachably connected to the first cable 731 and the third cable 733, respectively. Specifically, the two ends of the first cable 731, the second cable 732, and the third cable 733 are respectively provided with a screw head and a nut head. The screw head can be screwed into the nut head, providing versatility and allowing the number of cables to be selected according to the length of the rod assembly 1. The rotating sleeve 71 is provided with a threaded connection groove 75, into which the screw head on the cable 73 can be screwed.

[0071] Multiple pulleys 74 are provided, and their number and position are determined according to the length of the cable 73. Specifically, in this embodiment, two pulleys 74 are provided: one on the fixed housing 3 and one on the connecting frame 2. Since the direction of movement of the cable 73 is different from the direction of movement of the moving rod 62, the pulleys 74 are provided. The pulleys 74 guide the cable 73, changing the direction of the force applied to the cable 73, thus enabling the moving rod 62 to move.

[0072] Along the axial direction of the rod assembly 1, multiple cable positioning rings are spaced apart on the rod assembly 1. The cable 73 is wound around the pulley 74 and then passes through the cable positioning rings in sequence and is connected to the rotating sleeve 71. The cable 73 can slide within the cable positioning rings. The cable positioning rings play a positioning role for the cable 73, preventing the cable 73 from being hooked on other objects during operation and ensuring the safety of the operation.

[0073] When using the installation device provided in this embodiment, the cotter pin is placed on the clamping end of the clamping assembly 4, and the clamping end of the clamping assembly 4 is driven by the driving assembly 7 to clamp the cotter pin. At the same time, the pushing member 5 moves away from the clamping end of the clamping assembly 4. After the cotter pin is partially inserted into the cable connector, the clamping assembly 4 releases the cotter pin and the pushing member 5 pushes the cotter pin onto the cable connector.

[0074] Example 2

[0075] like Figure 1 and Figure 11 As shown, this embodiment provides an installation device for a moving cotter pin in a power grid. The structure of the installation device is the same as that in Embodiment 1. The installation device also includes a receiving component 8. The receiving component 8 is disposed on the pole assembly 1 and close to the connecting frame 2. The receiving component 8 is used to receive the cotter pin, preventing the cotter pin from falling and hitting the technicians, thus improving the safety factor of the operation.

[0076] Optionally, the receiving assembly 8 includes a fixing ring 81, a linkage rod 82, and a receiving cloth 83. The fixing ring 81 is sleeved on the rod assembly 1. Multiple linkage rods 82 are provided, spaced apart circumferentially along the fixing ring 81, with one end of each linkage rod hinged to the fixing ring 81. Multiple connecting buckles 84 are provided along the edge of the receiving cloth 83. The rod assembly 1 passes through the center of the receiving cloth 83, and the other end of each linkage rod 82 is inserted into a corresponding connecting buckle 84. This receiving assembly 8 allows the receiving cloth 83 to be removed and the linkage rod 82 folded when the installation device is not used, facilitating storage and carrying. When using the installation device, the rod assembly 1 is passed through the receiving cloth 83, the linkage rod 82 is unfolded, and the linkage rod 82 is inserted into the connecting buckle 84 of the receiving cloth 83 for easy assembly.
