Description

Technical Field

[0001] This utility model relates to the technical field of live-line working tools, specifically to a concealed live-line working insulating rod concealed suspension frame for high-voltage power work. Background Technology

[0002] In live-line working scenarios at 10kV and above, insulating rods are the core tool for achieving live-line operations. The convenience and safety of their storage and retrieval directly affect work efficiency and personnel safety. Currently, there is no standardized temporary placement scheme for insulating rods in the industry, and in practice, there is a common problem of chaotic tool management: most work teams directly hang insulating rods on the crossarms of power towers. Since the crossarms are made of metal and lack a dedicated fixing structure, the insulating rods are easily affected by external forces such as wind and operational vibrations, which can cause them to sway. This can not only cause wear and tear on the insulation layer due to collisions with the metal parts of the tower, but also create a conductive path due to accidental contact of the exposed multi-functional metal operating head, posing a significant safety hazard.

[0003] A more prominent problem lies in the tool passing process: different types of insulating rods, such as insulating sleeve locking rods and parallel groove clamp operating rods, need to be used alternately during operations. If there is no nearby suspension device, workers on the poles must repeatedly pass the tools to ground personnel via ropes, which takes a lot of time per pass and wastes construction time. More seriously, frequent passing causes the insulating rods to repeatedly rub against the tower and ropes. Tests have shown that after six months of use, the surface of the insulation layer of the passing tools shows wear of 0.2-0.5mm, and the insulation resistance value is 15%-20% lower than that of brand-new tools. Some old tools even fail the withstand voltage test due to local damage, becoming potential safety risks.

[0004] Furthermore, prolonged exposure to the elements accelerates tool aging: while the core material of insulating rods, epoxy resin fiberglass, possesses high-voltage resistance, it gradually oxidizes under direct ultraviolet radiation and rain / snow erosion. Survey data shows that insulating rods stored without protective measures have a lifespan more than 30% shorter than those stored indoors according to regulations, and require an additional 20% increase in annual inspection and maintenance costs. Simultaneously, the mixed hanging of insulating rods with different functions necessitates individual identification during retrieval, further prolonging the operational process and hindering the efficient implementation of live-line work.

[0005] In conclusion, it is evident that a new type of concealed suspension bracket for live-line working insulating poles urgently needs to be developed. Utility Model Content

[0030] like Figure 1-3 As shown, a concealed live-line working insulating pole concealed suspension frame includes a suspension frame body, which includes a mounting part 1 that is detachably connected to the crossarm of the power line tower and a movable part 15 for suspending the insulating pole.

[0031] Mounting part 1: Its inner side is a space groove 4. The upper and lower parts of the space groove 4 are respectively provided with crossarm connection holes 3, which are used to fix the mounting part 1 to the crossarm of the power tower by bolts and other fasteners. The space groove 4 is provided with several sets of magnetic modules 17 and hanging ring structures 5. The magnetic modules 17 are used to attract the metal parts of the insulating rod to enhance the suspension stability. The hanging ring structure 5 is adapted to the multi-functional metal operating head of the live working operating rod to realize the suspension positioning of the insulating rod. The bottom of the mounting part 1 is a bearing plate 8. The bearing plate 8 is provided with a through hole structure 19 corresponding to the hanging ring structure 5 in the middle, so that the rod body of the insulating rod can pass through to avoid the rod body swaying when suspended.

[0032] The movable part 15 is rotatably connected to the support plate 8 via the hinge 9, and can rotate around the hinge 9 to a hidden state that fits against the mounting part 1 or an unfolded state for use; a hook structure 10 is fixed below the movable part 15 via the connecting part 11. The hook structure 10 is used to suspend long or specially structured insulating rods, and works with the hanging ring structure 5 to achieve classified suspension of various types of insulating rods.

[0033] The mounting part 1 and the top of the movable part 15 are respectively connected to the insertion hole 2 via the insertion part 16. When the movable part 15 is unfolded to the use state, the insertion part 16 is inserted into the insertion hole 2, which can restrict the rotation of the movable part 15 and ensure the structure is stable when suspended. When it is necessary to hide and store it, the insertion part 16 is pulled out, and the movable part 15 can rotate around the hinge 9 to fit with the mounting part 1, so as to achieve the hiding effect.

[0034] The movable part 15 has a covered tool storage slot 12 in the middle of its outer side. The tool storage slot 12 has a tool insertion and fixing bracket 13 inside. The tool storage slot 12 can be used to store small auxiliary tools, such as insulating gloves, connecting buckles, etc. The tool insertion and fixing bracket 13 can position the tools and prevent them from shaking and falling off. The cover of the tool storage slot 12 is made of transparent explosion-proof glass, which makes it convenient for operators to see the tools inside. It also has impact resistance and high pressure resistance.

[0035] The movable part 15 is provided with a pull ring 14 on the upper side. When it is necessary to separate or unfold the movable part 15 from the mounting part 1, the operator can apply force through the pull ring 14, which is convenient.

[0036] The hanging ring structure 5 includes a square fixing block with a through-hole 6 on its side. After the square fixing block is sleeved with the connecting post 18 located on the back side of the space slot 4, it is locked by bolts passing through the through-hole 6 and the center of the connecting post 18. This structure facilitates the disassembly and replacement of the hanging ring structure 5, and allows for the replacement of a suitable hanging ring structure 5 according to the size of the metal operating head of the insulating rod, thus improving versatility.

[0037] The front end of the hanging ring structure 5 is provided with a suspension ring 7. The inner diameter of the suspension ring 7 is adapted to the multi-functional metal operating head of the insulating rod to ensure that the insulating rod does not fall off when suspended.

[0038] The main body of the suspension frame is made of epoxy resin glass fiber composite material, which can withstand 10kV high voltage, has excellent insulation performance, and meets the safety requirements for live working. The surface of the main body is coated with a UV-resistant coating, which can resist sun aging and extend service life. The outer shell of the main body is also equipped with an information labeling area for marking the voltage resistance level, service life and manufacturer information, which facilitates management and maintenance.

[0039] The working principle and process of this utility model:

[0040] As shown in Figure 1, the concealed live-line working insulating rod concealed suspension frame of this utility model includes an installation part 1 and a movable part 15. The installation part 1 is a frame structure, and the inner space groove 4 is used to accommodate part of the crossarm structure. It is fixed to the crossarm bolts through the upper and lower crossarm connecting holes 3. The magnetic attraction module 17 in the middle of the space groove 4 is a strong magnetic block, which can attract the metal operating head of the insulating rod to enhance the suspension stability. The hanging ring structure 5 is fixed in the space groove 4 through the connecting column 18. The hanging ring 7 at its front end is adapted to the multi-functional metal operating head of the insulating rod as shown in Figure 3. The rod body of the insulating rod can pass through the through hole structure 19 of the bearing plate 8 to avoid shaking and maintain stability.

[0041] The movable part 15 is connected to the support plate 8 via a hinge 9 and can rotate around the hinge 9. In use, pulling the pull ring 14 rotates the movable part 15 to be perpendicular to the mounting part 1. At this time, the insertion part 16 of the mounting part 1 is inserted into the insertion hole 2 of the movable part 15 to achieve locking. The hook structure 10 below the movable part 15 can hang long rod-like insulating rods. When not in use, the insertion part 16 is pulled out, and the movable part 15 is rotated to fit snugly against the mounting part 1 to achieve concealed storage.

[0042] Use of tool storage slots

[0043] The tool storage slot 12 on the outside of the active section 15 has a transparent explosion-proof glass cover, and the tool insertion and fixing bracket 13 inside can insert small tools such as insulated wrenches and connecting clips to prevent tools from being lost and make them easy to access during operation.

[0044] Materials and Labels

[0045] The main body of the suspension frame is made of epoxy resin fiberglass composite material, and the surface is coated with a UV-resistant coating; the information label area of ​​the outer shell is printed with information such as resistance to 10kV high voltage and service life of 5 years, which facilitates compliant management and maintenance.

[0046] Example 1: Live-line maintenance scenario for 10kV distribution lines

[0047] In live-line maintenance of 10kV distribution lines, workers need to insulate line joints, requiring the alternating use of three different types of insulating rods: insulating sleeve locking rods, parallel groove clamp operating rods, and others. The mounting part of this invention is fixed to the metal crossarm of the utility pole through the crossarm connection hole, with the space groove fitting snugly against the side of the crossarm for concealed installation.

[0048] Unfold the movable part 15 and lock it with the mounting part 1 via the plug-in part 16. At this time, the suspension 7 of the hanging ring structure 5 is aligned with the through hole structure 19 of the bearing plate. The operator hangs the metal operating head of the insulating sleeve locking rod into the hanging ring 7. The rod passes through the through hole structure, and the magnetic module 17 attracts the metal operating head to enhance stability. Hang the parallel groove clamp operating rod on the hook structure 15 of the movable part to complete the tool mounting. During maintenance, the operator can directly take the required tools from the hanging ring or hook without the need for ground transfer. When changing tools, the used insulating rod can be easily hung back in its original position.

[0049] After the work is completed, the plug is pulled out, and the movable part 15 rotates around the hinge 9 until it fits against the mounting part 1. It is then fixed with the help of the magnetic module 17. The overall structure is integrated with the crossarm, achieving hidden storage without affecting the normal operation of the line.

[0050] Example 2: Live-line operation scenario of high-voltage cable branch box

[0051] During live-line operations on high-voltage cable branch boxes, tools such as insulated operating rods and voltage detector operating rods are required, along with small auxiliary tools such as insulated gloves and connecting clips. The concealed live-line working insulated rod is fixed to a special crossarm on the outside of the branch box, and the magnetic module of the space slot adheres to the metal part of the crossarm for auxiliary positioning.

[0052] After the activity section 15 is unfolded, the hanging ring structure 5 suspends the insulating operating rod, and the hook structure 10 suspends the voltage detector operating rod. The two are placed separately to avoid confusion. In the tool storage slot 12 of the activity section, the insulating gloves and connecting buckles are fixed by the tool plug-in fixing bracket. The transparent cover makes it easy to quickly check whether the tools are complete.

[0053] During operation, the operator stands on the insulated platform and can reach the operating rod from the hanging ring or hook. If auxiliary tools are needed, they can be directly opened and taken from the storage tank cover.

[0054] After the work is completed, put the tool back in place, fold the movable part 15 to fit snugly with the mounting part 1, and lock it in place by the plug-in part 16. The whole structure is hidden on the side of the branch box, does not occupy the maintenance passage, and avoids the tool being exposed to outdoor rain and snow.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
