Description

Technical Field

[0001] This utility model relates to the field of overhead contact line conversion posts, and in particular to an overhead contact line conversion post used during construction without interrupting subway operation. Background Technology

[0002] The overhead contact line conversion post is a special support used in the overhead contact line system of electrified railways to support two contact suspensions (working support and non-working support) at the joint of the anchor section and to achieve a smooth transition of the pantograph. Its core function is to ensure that the electric locomotive does not lose power and has reliable mechanical stability when switching between different anchor sections.

[0003] In practical applications, the existing contact wire conversion posts have a relatively complete structure and function, which can meet basic usage requirements, but the following problems still exist:

[0004] When transitioning between the old and new power grids, the existing overhead contact line conversion poles require shutting down the power supply system, which means the subway can only be shut down before the upgrade can be carried out. This is very inconvenient. In addition, during the disassembly and assembly of the overhead contact line conversion poles, components such as the cantilever base are fixed to the pole by welding connecting plates and multiple bolts. This process makes the disassembly and assembly of components such as the cantilever base very inconvenient.

[0005] Therefore, this utility model provides a catenary conversion column for construction without interrupting subway operation. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a catenary conversion column for construction without interrupting subway operation.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a contact wire conversion column for construction under subway non-stop operation, comprising a mounting column and two cantilever bases. Two support clamps are symmetrically installed on one side of each of the two cantilever bases. A first rod-type insulator is installed on one side of the upper support clamp, and one end of the first rod-type insulator is fixedly connected to a cantilever tube. A second rod-type insulator is installed on one side of the lower support clamp, and one end of the second rod-type insulator is fixedly connected to a slanted cantilever. A positioning clamp is provided between the slanted cantilever and the cantilever tube. A disassembly and fixing structure is provided between the mounting column and the cantilever base. The disassembly and fixing structure includes a mounting plate, and two mounting rods are symmetrically fixedly connected to one side of the mounting plate.

[0008] In a preferred embodiment, the outer surfaces of both the wrist arm tube and the inclined wrist arm are provided with sling clamps, a sling body is provided between the two sling clamps, and mounting clamps are installed at the bottom of both inclined wrist arms. A long contact arm is installed on one side of one of the mounting clamps, and a short contact arm is installed at one end of the other mounting clamp.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the long contact arm and the short contact arm, it is possible to make contact with the old and new lines simultaneously during the transition and utilization of the old and new lines. Thus, during the renewal and transition of the old and new lines, there is no need to shut down the lines, and a rapid transition and utilization can be achieved.

[0010] In a preferred embodiment, a second insertion hole is provided on one side of the mounting plate, and a first insertion hole is provided on one side of the wrist arm base. A first threaded rod is inserted into the inner wall of the first and second insertion holes, and a first fixing nut is threaded to one end of the first threaded rod.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the first threaded rod, the cantilever base and the mounting plate can be disassembled and assembled. At the same time, during disassembly, only the first threaded rod needs to be disassembled to complete the disassembly, which is very convenient.

[0012] In a preferred embodiment, a second threaded rod is inserted into the inner wall of the third and fourth insertion holes, and a second fixing nut is fixedly connected to one end of the second threaded rod.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the second threaded rod, in cooperation with the third and fourth insertion holes, the mounting post and mounting rod can be fixed, thereby allowing the mounting plate and other components to be disassembled and assembled.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By incorporating components such as a first-bar insulator, a second-bar insulator, a cantilever tube, an inclined cantilever, and long and short contact arms, this contact network conversion column is suitable for installation on steel columns in double-bearing double-conductor chain suspension and simple suspension non-insulated anchor section joint conversion columns. It can utilize existing power supply systems, enabling rapid transition and utilization of old and new lines, ultimately achieving uninterrupted construction. This method allows for the rapid transition and utilization of existing power supply systems and the rapid upgrading of new power supply systems. Through the design of a disassembly and assembly structure, the disassembly and assembly between the cantilever base and the mounting column is divided into two parts: the first part involves the disassembly and assembly between the mounting plate and the mounting column, which is not easily disassembled; the second part involves the disassembly and assembly between the mounting plate and the cantilever base, which requires disassembly, maintenance, and replacement based on actual usage conditions. This eliminates the need to disassemble all components during disassembly and assembly, simplifying the process and improving efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4 As shown, this embodiment provides a technical solution: a contact wire conversion column for construction under subway non-stop operation, including a mounting column 12 and two cantilever bases 1. Two support clamps 3 are symmetrically installed on one side of each cantilever base 1. A first rod-type insulator 2 is installed on one side of the upper support clamp 3, with a cantilever tube 4 fixedly connected to one end of the first rod-type insulator 2. A second rod-type insulator 5 is installed on one side of the lower support clamp 3, with a slanted cantilever 6 fixedly connected to one end of the second rod-type insulator 5. A positioning clamp 11 is provided between the slanted cantilever 6 and the cantilever tube 4. A disassembly and fixing structure 9 is provided between the mounting column 12 and the cantilever base 1. The disassembly and fixing structure 9 includes a mounting plate 92, with two mounting rods 96 symmetrically fixedly connected to one side of the mounting plate 92. The structure utilizes the first rod-type insulator 2, the second rod-type insulator 5, the cantilever tube 4, the slanted cantilever 6, and the long... Components such as contact arm 8 and short contact arm 10 are suitable for installation on steel columns of double-bearing double-guide chain type suspension and simple suspension non-insulated anchor section joint conversion columns. They can utilize the old power supply system, and through this contact network conversion column, the transition and utilization of old and new lines can be quickly realized, ultimately achieving uninterrupted construction. The old power supply system can be quickly transitioned and utilized in this way, and the newly built power supply system can be quickly updated. By setting up the disassembly and fixing structure 9, the disassembly and assembly between the cantilever base 1 and the mounting column 12 is divided into two parts. The first part is the disassembly and assembly between the mounting plate 92 and the mounting column 12, which is not easily disassembled. The second part is the disassembly and assembly between the mounting plate 92 and the cantilever base 1. This disassembly and assembly needs to be carried out according to the actual use situation for maintenance and replacement. Therefore, it is not necessary to disassemble all components during disassembly and assembly, which simplifies the disassembly and assembly steps and improves efficiency.

[0026] Going further, such as Figures 1-2As shown: both the outer surfaces of the cantilever tube 4 and the inclined cantilever 6 are provided with sling clamps 13, and a sling body 14 is provided between the two sling clamps 13. The bottom of both inclined cantilever 6 is equipped with mounting clamps 7. One side of one mounting clamp 7 is equipped with a long contact arm 8, and one end of the other mounting clamp 7 is equipped with a short contact arm 10. Under the action of the long contact arm 8 and the short contact arm 10, the new and old lines can be contacted simultaneously during the transition and utilization of the new and old lines. Thus, during the renewal and transition of the new and old lines, there is no need to shut down the lines, and a rapid transition and utilization can be achieved.

[0027] The above solution also has the problem of direct disassembly and assembly between the cantilever base 1 and the mounting column 12, which requires the removal of multiple bolts and is very inconvenient. Figure 3 and Figure 4 As shown: In this solution, a second insertion hole 93 is provided on one side of the mounting plate 92, and a first insertion hole 91 is provided on one side of the arm base 1. A first threaded rod 94 is inserted into the inner wall of the first insertion hole 91 and the second insertion hole 93. A first fixing nut 95 is threaded to one end of the first threaded rod 94. Under the action of the first threaded rod 94, the arm base 1 and the mounting plate 92 can be disassembled and assembled. At the same time, during disassembly, only the first threaded rod 94 needs to be disassembled to complete the disassembly, which is very convenient.

[0028] The above solutions also have the problem that the mounting plate 92 and the mounting column 12 are usually fixed by welding, which makes disassembly inconvenient. Figure 4 As shown, a second threaded rod 99 is inserted into the inner wall of the third insertion hole 97 and the fourth insertion hole 98. A second fixing nut 910 is fixedly connected to one end of the second threaded rod 99. Under the action of the second threaded rod 99, it cooperates with the third insertion hole 97 and the fourth insertion hole 98 to fix the mounting post 12 and the mounting rod 96, thereby allowing the mounting plate 92 and other components to be disassembled and assembled.

[0029] Working principle:

[0030] like Figure 1-4 As shown:

[0031] In use, the first rod insulator 2 and the second rod insulator 5 are installed to the cantilever base 1 via the support clamp 3. The cantilever tube 4 and the inclined cantilever 6, which are fixedly connected to the first rod insulator 2 and the second rod insulator 5, are fixed to the two cantilever bases 1 respectively. The inclined cantilever 6 is then fixed to the cantilever tube 4 via the positioning clamp 11. The cantilever tube 4 and the inclined cantilever 6 are then connected to the sling body 14 via the sling clamp 13. The long contact arm 8 and the short contact arm 10 can then be installed via the installation clamp 7. The cantilever base 1 is then attached to the mounting plate 92 so that the first insertion hole 91 and the second insertion hole 93 are aligned. The first threaded rod 94 is then inserted into the interior of the first insertion hole 91 and the second insertion hole 93. The first fixing nut 95 is then fixed to the first threaded rod 94. The second threaded rod 99 is then inserted into the inner wall of the third insertion hole 97 and the fourth insertion hole 98. The second fixing nut 910 is then fixed to the second threaded rod 99.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
