Detailed implementation mode
[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0031] Please refer to Figure 1-8 , the present utility model provides a technical solution: a suspension string device for an electrified railway catenary system with adjustable length, including a suspension string body 1, a carrier cable 2, a contact wire 3, a support column 4, a fixed clamp block 5, a connecting plate 6, a fixed connecting column 7, a fixed connecting sleeve 8, a fixed connecting groove 9, an adjusting component 10, an adjusting bracket 11, a limiting rod 12, a movable plate 13, a pressing block 14 and a connecting cap 15.
[0032] When using the suspension string device for the electrified railway catenary system with adjustable length, the operator stands on the ladder truck and holds the suspension string body 1 to perform relevant operations, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, support columns 4 are fixedly connected to both the upper and lower ends of the suspension string body 1. Combining with the setting of the fixed clamp block 5, the fixed clamp blocks 5 are respectively hinged to the front and rear sides of the support column 4. Place the fixed clamp blocks 5 outside the carrier cable 2 and the contact wire 3. By flipping the fixed clamp blocks 5, the fixed clamp blocks 5 rotate with the support column 4, and the fixed clamp blocks 5 are respectively clamped at appropriate positions outside the carrier cable 2 and the contact wire 3. At the same time, a connecting plate 6 is fixedly connected to the side of the fixed clamp block 5 away from the suspension string body 1. The fixed connecting column 7 is connected to the connecting plate 6 in a card slot manner. Then, rotate the fixed connecting sleeves 8 threadedly connected to the front and rear ends of the fixed connecting column 7 so that the fixed connecting sleeves 8 are snap-fitted into the fixed connecting groove 9, thereby facilitating the limitation between the fixed connecting column 7 and the connecting plate 6 and realizing the positioning between the fixed clamp blocks 5 on the front and rear sides, so as to quickly disassemble and assemble between the suspension string body 1 and the carrier cable 2 and between the suspension string body 1 and the contact wire 3;
[0033] Combining Figure 6 Figure 7 and Figure 8The shown adjusting assembly 10 is arranged in the middle of the suspension string body 1, and the adjusting assembly 10 includes an adjusting bracket 11 for connection, limiting rods 12 fixedly connected to the upper and lower ends of the adjusting bracket 11, a movable plate 13 sleeved outside the limiting rods 12, a pressing block 14 for pressing and fixing, and a connection cap 15 with a limiting function. The adjusting bracket 11 is connected to the suspension string body 1 by a card slot. According to the actual on-site use requirements, by pulling the suspension string body 1, relative movement occurs between the suspension string body 1 and the adjusting assembly 10, thereby facilitating the adjustment of the length of the suspension string body 1 and realizing the overall retraction and extension adjustment of the suspension string body 1;
[0034] When adjusted to the corresponding length, by rotating the connection cap 15 threadedly connected to the outer surface of the limiting rod 12, the connection cap 15 is in a fitting setting with the movable plate 13. The connection cap 15 drives the movable plate 13 to slide with the limiting rod 12, and a pressing block 14 is fixedly connected to the middle of the movable plate 13, so that the movable plate 13 drives the pressing block 14 to clamp on the suspension string body 1, thereby facilitating the limitation between the adjusting assembly 10 and the suspension string body 1 and preventing loosening between the suspension string body 1 and the adjusting assembly 10.
[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
