Description

Technical Field

[0001] This application relates to the technical field of power fittings, and in particular to a tower connection fitting. Background Technology

[0002] The connecting hardware on the transmission line is mainly used to bridge power devices such as insulator strings or clamps to the tower material. The connecting hardware bears the largest load and is prone to breakage under severe external forces such as strong winds or icing.

[0003] In traditional technology, when the bowl-shaped mounting plate is used as a connecting hardware for towers, the contact between the mounting bracket and the connecting bolt in the bowl-shaped mounting plate is a point contact. This causes the stress on the connecting bolt to be concentrated at the contact point between the connecting bolt and the mounting bracket. When the power device is affected by harsh environments such as strong winds or icing, the connecting bolt may break due to uneven stress, which may cause the power device to fall from a height. Utility Model Content

[0004] Therefore, it is necessary to provide a connecting bolt fitting to address the problem of electrical devices falling from heights due to uneven stress on connecting bolts in traditional technologies.

[0005] The technical solution is as follows:

[0006] One embodiment provides a tower connection fitting, comprising:

[0007] An assembly rack is provided with an assembly through slot. The opening of the assembly through slot is opened along a first direction of the assembly rack, and the opposite sides of the assembly through slot are connected along a second direction of the assembly rack. The second direction is perpendicular to the first direction.

[0008] A first connecting mechanism is provided through the assembly slot along the second direction of the assembly frame. The first connecting mechanism abuts against the slot wall and is used to connect with the tower material. The contact surface between the first connecting mechanism and the slot wall is a continuous structure.

[0009] A second connecting mechanism is rotatably disposed at one end of the assembly frame near the slot, and the second connecting mechanism is used to connect electrical devices.

[0010] In the aforementioned connecting frame hardware, the first connecting mechanism passes through the assembly slot along the second direction of the assembly frame, allowing it to abut against the slot wall. When the load of the power device is transferred to the first connecting mechanism via the second connecting mechanism, the continuous contact surface between the first connecting mechanism and the slot wall results in a larger contact area between the slot wall and the first connecting mechanism in the second direction of the assembly frame. This makes the stress on the first connecting mechanism from the assembly frame more uniform, thus preventing stress concentration and breakage due to insufficient force-bearing area. Simultaneously, when the power device and connecting frame hardware move due to environmental factors such as wind or icing, the power device can rotate freely relative to the assembly frame via the second connecting mechanism, preventing excessive torsion and breakage. Compared to traditional technologies, the aforementioned connecting frame hardware increases the contact area between the first connecting mechanism and the assembly frame, allowing the first connecting mechanism to bear force evenly, and the second connecting mechanism enables the power device to rotate freely, preventing breakage due to movement caused by environmental factors such as wind.

[0011] In one embodiment, the first connecting mechanism includes a connecting rod whose axial direction is parallel to the second direction, the sidewall of the connecting rod abutting against the groove wall, the contact surface between the sidewall of the connecting rod and the groove wall being a continuous structure, and at least one end of the connecting rod protruding outside the assembly through groove and used for connecting with the tower material.

[0013] In one embodiment, the first connecting mechanism further includes a locking pin, the shank of the bolt having a locking through hole, the locking pin passing through the locking through hole and abutting against the nut on the side away from the second connecting portion.

[0014] In one embodiment, the first connecting mechanism further includes a first washer, through which the bolt passes, and the first washer is sandwiched between the first connecting portion and the head of the bolt; or / and,

[0015] The first connecting mechanism further includes a second washer, through which the bolt passes and the second washer is sandwiched between the second connecting portion and the nut.

[0016] In one embodiment, the second connecting mechanism includes a mounting base and a hanger rod. The mounting base is connected to one end of the assembly frame near the slot and has a mounting cavity. The bottom wall of the mounting base has a first opening communicating with the mounting cavity. One end of the hanger rod has a mounting part that passes through the first opening. The mounting part is located inside the mounting cavity and can rotate inside the mounting cavity, thereby driving the hanger rod to rotate synchronously.

[0017] In one embodiment, the side wall of the mounting base has a second opening that communicates with the mounting cavity. The second opening is connected to the first opening, and the mounting part can enter and exit the mounting cavity through the second opening.

[0018] In one embodiment, the second connecting mechanism further includes an abutment member, and the side wall of the mounting base is provided with a communication hole communicating with the mounting cavity. One end of the abutment member passes through the communication hole and is located in the mounting cavity. The abutment member can reciprocate along the axial direction of the communication hole so that the abutment member can abut against the mounting part.

[0019] In one embodiment, the abutting member includes an abutting portion and a guiding portion. The abutting portion is disposed at one end of the guiding portion, the guiding portion passes through the communicating hole, and the abutting portion is located in the mounting cavity and is used to abut the mounting portion.

[0033] Please see Figure 1 and Figure 3 One embodiment of this application provides a tower connection fitting, including an assembly frame 100, a first connecting mechanism 200, and a second connecting mechanism 300. The assembly frame 100 is provided with an assembly through slot 110, the slot opening 111 of the assembly through slot 110 is opened along a first direction of the assembly frame 100, and the opposite sides of the assembly through slot 110 are connected along a second direction of the assembly frame 100, the second direction being perpendicular to the first direction. The first connecting mechanism 200 is disposed in the assembly through slot 110 along the second direction of the assembly frame 100, the first connecting mechanism 200 abuts against the slot wall of the assembly through slot 110 and is used to connect with the tower material 400, the contact surface between the first connecting mechanism 200 and the slot wall is a continuous structure. The second connecting mechanism 300 is rotatably disposed at one end of the assembly frame 100 near the slot opening 111, and the second connecting mechanism 300 is used to connect electrical devices.

[0034] In the aforementioned connecting bracket, the first connecting mechanism 200 passes through the assembly slot 110 along the second direction of the assembly frame 100, allowing the first connecting mechanism 200 to abut against the slot wall of the assembly slot 110. When the load of the power device is transmitted to the first connecting mechanism 200 through the second connecting mechanism 300, because the contact surface between the first connecting mechanism 200 and the slot wall is a continuous structure, the slot wall of the assembly slot 110 has a larger contact area with the first connecting mechanism 200 in the second direction of the assembly frame 100. This makes the stress on the first connecting mechanism 200 from the assembly frame 100 more uniform, thereby preventing the first connecting mechanism 200 from being subjected to stress. The 00 fractures due to stress concentration caused by insufficient force-bearing area. At the same time, when the power device and the connecting frame hardware move due to environmental factors such as wind or icing, the power device can rotate freely relative to the mounting frame 100 through the second connecting mechanism 300 to prevent the power device from causing excessive torsion to the mounting frame 100 and thus breaking. Compared with the conventional technology, the above-mentioned connecting frame hardware increases the contact area between the first connecting mechanism 200 and the mounting frame 100, so that the first connecting mechanism 200 can be evenly stressed, and the power device can be driven to rotate freely through the second connecting mechanism 300 to prevent the connecting frame hardware from breaking due to movement caused by environmental factors such as wind.

[0035] For explanation, the continuous structure between the first connecting mechanism 200 and the groove wall refers to the groove wall having a larger contact area with the first connecting mechanism 200 in the second direction. For example, when the first connecting mechanism 200 is columnar, the groove wall matches the shape of the first connecting mechanism 200 and extends along the axial direction of the columnar first connecting mechanism 200, so that the side wall of the columnar first connecting mechanism 200 and the groove wall can fit tightly together.

[0036] Furthermore, the second connecting mechanism 300 can rotate relative to the assembly frame 100 so that the first connecting mechanism 200 can be used to connect with the tower material 400 in any direction, avoiding the situation where the connecting hardware is scrapped due to inconsistent connection directions; for example, when the first connecting mechanism 200 is a bolt 210, the bolt 210 can rotate at any angle relative to the power device so that the bolt 210 can be used to connect with the tower material 400 in any direction.

[0037] Further, please refer to Figure 1 and Figure 3The assembly frame 100 is formed by bending a plate. The two ends of the plate extend in the same direction along the first direction to form an inverted U-shaped assembly slot 110. The assembly slot 110 needs to have a reasonable slot width to ensure that the first connecting mechanism 200 forms a surface contact with the slot wall of the inverted U-shaped assembly slot 110. In this application, the first connecting mechanism 200 passes through the assembly slot 110 along the second direction of the plate, and the first connecting mechanism 200 can rotate within the assembly slot 110 so that the power device can have a certain degree of swing freedom relative to the tower material 400.

[0038] For illustrative purposes, in the above embodiments, the first direction is the length direction of the plate, and the second direction is the width direction of the plate.

[0039] Furthermore, since the assembly slot 110 is an inverted U-shaped slot, the first connecting mechanism 200 can also reciprocate within the assembly slot 110 along its depth direction, thereby causing the assembly frame 100 to swing in a direction perpendicular to the first connecting mechanism 200. Thus, when the power device wobbles or vibrates due to environmental factors such as wind, it can move the first connecting mechanism 200 along the depth direction of the assembly slot 110, further preventing damage to the first connecting mechanism 200 and the assembly slot 110 due to excessive force.

[0040] In one embodiment, the first connecting mechanism 200 includes a connecting rod whose axial direction is parallel to the second direction, the sidewall of the connecting rod abutting against the groove wall, the contact surface between the sidewall of the connecting rod and the groove wall having a continuous structure, and at least one end of the connecting rod protruding from the assembly through groove 110 and used for connection with the tower material 400.

[0041] The connecting rod passes through the assembly slot 110 along the second direction of the assembly frame 100, and the axis of the connecting rod is parallel to the second direction of the assembly frame 100. The side wall of the connecting rod can abut against the slot wall of the assembly slot 110, so that the slot wall of the assembly slot 110 has a larger contact area with the side wall of the connecting rod in the second direction of the assembly frame 100, thereby making the stress on the connecting rod more uniform and preventing the connecting rod from breaking. At least one end of the connecting rod protrudes out of the assembly slot 110 to facilitate connection with the tower material 400. The structure is simple and the connection effect is reliable.

[0042] In some embodiments, one end of the connecting rod is located in the mounting slot 110, and the other end protrudes from the mounting slot 110. The end protruding from the mounting slot 110 is used to connect with the tower material 400, and the connection method can be welding, threading, etc. In other embodiments, both ends of the connecting rod protrude from the mounting slot 110, and both ends are used to connect with the tower material 400, thereby achieving a more stable and reliable connection with the tower material 400, which will not be elaborated here.

[0043] Please see Figures 1 to 3 In one embodiment, the first connecting mechanism 200 includes a bolt 210 and a nut 220, and the tower material 400 includes a first connecting part 410 and a second connecting part 420. The first connecting part 410 has a first connecting hole, and the second connecting part 420 has a second connecting hole. The bolt 210 passes through the first connecting hole, the mounting slot 110, and the second connecting hole in sequence and is screwed to the nut 220. The contact surface between the side wall of the bolt 210 and the slot wall has a continuous structure.

[0044] After the bolt 210 passes through the first connecting hole, the assembly slot 110 and the second connecting hole in sequence, it is screwed onto the nut 220. In this way, the first connecting part 410 can be positioned between the head of the bolt 210 and the assembly frame 100, and the second connecting part 420 can be positioned between the nut 220 and the assembly frame 100. This prevents the first connecting mechanism 200 from falling off the assembly slot 110, which would cause the tower fittings and power components to fall off together. This method has low implementation cost and can ensure the assembly stability between the tower fittings and the tower material 400.

[0045] Furthermore, the bolt 210 can abut against the groove wall of the assembly slot 110, so that the groove wall of the assembly slot 110 has a larger contact area with the side wall of the bolt in the second direction of the assembly frame 100, so that the bolt 210 is subjected to more uniform force and the bolt breaks.

[0046] Please see Figure 1 and Figure 2 In one embodiment, the first connecting mechanism 200 further includes a locking pin 230, the shank of the bolt 210 is provided with a locking through hole, and the locking pin 230 passes through the locking through hole and abuts against the side of the nut 220 away from the second connecting portion 420.

[0047] The locking pin 230 can prevent the nut 220 from falling off the bolt 210, further preventing the connecting tower hardware from falling off and reducing safety hazards.

[0048] Furthermore, the axial direction of the locking through hole is perpendicular to the axial direction of the bolt 210.

[0049] In one embodiment, the first connecting mechanism 200 further includes a first washer, a bolt 210 passing through the first washer, and the first washer being sandwiched between the first connecting portion 410 and the head of the bolt 210.

[0050] The first washer sandwiched between the first connecting part 410 and the head of the bolt 210 can prevent the bolt 210 from being over-tightened, which would cause the head of the bolt 210 to be excessively squeezed against the first connecting part 410.

[0051] Please see Figures 1 to 2As an embodiment that can be implemented simultaneously with the above embodiments, the first connecting mechanism 200 further includes a second washer 240, a bolt 210 passing through the second washer 240, and the second washer 240 being sandwiched between the second connecting portion 420 and the nut 220.

[0052] Similarly, the second washer 240 sandwiched between the second connecting part 420 and the nut 220 can prevent the bolt 210 from being over-tightened, which would cause the nut 220 to over-compress the first connecting part 410.

[0053] Please see Figure 1 In one embodiment, the connecting tower fitting also includes a mounting base 310. The mounting base 310 is connected to one end of the assembly frame 100 near the slot 111 and has a mounting cavity 311. The bottom wall of the mounting base 310 has a first opening 312 communicating with the mounting cavity 311. The second connecting mechanism 300 includes a lifting rod 320. One end of the lifting rod 320 has a mounting part 321 that passes through the first opening 312. The mounting part 321 is located in the mounting cavity 311 and can rotate in the mounting cavity 311 and drive the lifting rod 320 to rotate synchronously.

[0054] The mounting part 321 at one end of the boom 320 is located in the mounting cavity 311. The mounting part 321 can rotate freely in the mounting cavity 311 to drive the boom 320 to rotate synchronously. In this way, when the power device and the tower fittings move due to environmental factors such as wind, the power device can rotate freely relative to the mounting frame 100 through the boom 320 to prevent the power device from causing excessive torsion to the mounting frame 100 and breaking.

[0055] Furthermore, the cross-sectional diameter of the boom 320 is smaller than the cross-sectional diameter of the mounting portion 321, and the diameter of the first opening 312 is smaller than the diameter of the mounting cavity 311. Thus, when the boom 320 passes through the first opening 312 and the mounting portion 321 is located in the mounting cavity 311, the mounting portion 321 will not fall off the mounting cavity 311 and can rotate 360° within the mounting cavity 311.

[0056] In one embodiment, the mounting base 310 and the mounting bracket 100 are integrally cast, resulting in low implementation cost and high strength.

[0057] Please see Figures 1 to 2 In one embodiment, the side wall of the mounting base 310 is provided with a second opening 313 that communicates with the mounting cavity 311. The second opening 313 is connected to the first opening 312, and the mounting part 321 can enter and exit the mounting cavity 311 through the second opening 313.

[0058] When assembling the tower connection hardware, the mounting part 321 is first inserted into the mounting cavity 311 through the second opening 313. Since the first opening 312 and the second opening 313 are connected to each other, the lifting rod 320 can be inserted into the first opening 312 so that the lifting rod 320 can rotate around the axis of the first opening 312. Similarly, when it is necessary to remove the lifting rod 320 from the mounting base 310, the operator holds the lifting rod 320 and removes the lifting rod 320 from the mounting base 310 at the connection between the first opening 312 and the second opening 313. At the same time, the mounting part 321 can also be removed from the mounting cavity 311 by the lifting rod 320. The implementation process is simple and the manufacturing cost is low.

[0059] Please see Figures 1 to 2 In one embodiment, the connecting tower fitting also includes an abutment 330. The side wall of the mounting base 310 is also provided with a communication hole communicating with the mounting cavity 311. One end of the abutment 330 passes through the communication hole and is located in the mounting cavity 311. The abutment 330 can reciprocate along the axial direction of the communication hole so that the abutment 330 can abut against the mounting part 321.

[0060] When the mounting part 321 enters the mounting cavity 311 through the second opening 313, the operator moves the abutment 330 along the axial direction of the connecting hole so that the abutment 330 abuts the mounting part 321, preventing the boom 320 from moving along its own axial direction and causing the boom 320 and the mounting part 321 to separate from the second opening 313.

[0061] Furthermore, the connecting part 330 is a W-type pin.

[0062] In one embodiment, the mounting cavity 311 includes a first cavity segment 314 and a second cavity segment 315 that are connected. The first cavity segment 314 is connected to and corresponds to the first opening 312, and the second cavity segment 315 is connected to and corresponds to the second opening 313. The cross-sectional diameter of the first cavity segment 314 is smaller than that of the second cavity segment 315. When assembling the tower fittings, the mounting part 321 is first placed into the second cavity segment 315 through the second opening 313. At this time, since the cross-sectional diameter of the second cavity segment 315 is larger, the mounting part 321 has a larger internal space for movement, so as to adjust the position of the mounting part 321 and allow the mounting part 321 to enter the first cavity segment 314 with a smaller cross-sectional diameter. At this time, the operator controls the abutment 330 to move and approach the second opening 313, so that the abutment 330 abuts against the mounting part 321 located in the first cavity segment 314. On the one hand, this can prevent the mounting part 321 from shaking randomly in the mounting cavity 311, and on the other hand, it can simplify the installation process and reduce the installation cost.

[0063] In one embodiment, the mounting part 321 is a flat disc shape. The disc surface of the mounting part 321 can not only effectively abut against the abutment 330, but also rotate 360° within the second cavity 315.

[0064] Please see Figures 1 to 3 In one embodiment, the abutting member 330 includes an abutting portion 331 and a guiding portion 332. The abutting portion 331 is disposed at one end of the guiding portion 332, the guiding portion 332 passes through the communicating hole, and the abutting portion 331 is located in the mounting cavity 311 and is used to abut the mounting portion 321.

[0065] The guide part 332 passes through the connecting hole, and the operator can control the movement of the guide part 332 through the end of the guide part 332 away from the mounting cavity 311, thereby controlling the abutment part 331 to abut against the mounting part 321.

[0066] Please see Figure 1 In one embodiment, the end of the boom 320 away from the mounting portion 321 is provided with a lifting ring 322, which is used to connect to an electrical device.

[0067] The power device can be suspended on the boom 320 via the lifting ring 322. In this way, the power device can also have a certain degree of flexibility after being connected to the lifting ring 322, preventing the boom 320 from breaking due to movement of the power device.

[0068] Furthermore, since the boom 320 can rotate relative to the mounting frame 100, the direction of the lifting ring 322 can also rotate with the boom 320, without affecting the connection direction of the power device connected to the lifting ring 322. This means that the prefabricated perforation direction of the tower material 400 for connecting bolts 210 is not limited to the displacement direction, and will not cause the power device and the tower material 400 to be inconsistent with the perforation design direction, resulting in the scrapping of the tower material 400 or the hardware, further reducing the difficulty and cost of operation.

[0069] For the explanation of electrical devices, insulators, suspension clamps, etc.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
