Description

Technical Field

[0001] This utility model relates to the technical field of S-hook devices, and in particular to an anti-detachment S-hook device for installing contact wire bearing conductors. Background Technology

[0002] The installation of overhead contact line conductors is a crucial construction step in railway electrification engineering. It involves erecting and fixing the overhead contact line, a special type of power transmission line that supplies electricity to electric locomotives, along the railway line. The overhead contact line is the main structure of railway electrification engineering, responsible for being erected along the railway line and supplying electricity to electric locomotives. The installation of overhead contact line conductors is one of the key control projects in railway electric traction power supply engineering, directly affecting the power supply and driving safety of trains. The S-hook device is used to hang the top of the conductor on the catenary cable during the installation process, thereby achieving temporary suspension and serving as a device for temporary positioning.

[0003] In the existing technology, since the S-hook does not have a limiting device, the catenary cable is prone to detach from the S-hook due to the shaking during the suspension process, which makes it impossible to effectively suspend the conductor, thus reducing the suspension efficiency and the working efficiency of the overhead contact line conductor erection. Therefore, it is necessary to improve the overhead contact line conductor erection S-hook device to solve the above problems. Utility Model Content

[0004] To overcome the problem that the lack of a limiting device for the S-hook causes the catenary cable to easily detach from the S-hook during suspension due to swaying, thus making effective suspension impossible.

[0005] The technical solution of this utility model is as follows: an S-hook device for anti-detachment contact wire support, including an S-hook body, a first optical axis, and a spring-loaded assembly. The spring-loaded assembly is installed inside the S-hook body. The first optical axis is rotatably connected inside the S-hook body. A first baffle is fixedly connected to the outside of the first optical axis. A sliding rod is slidably connected inside the first baffle. A sliding block is fixedly connected to the outside of the sliding rod. A spring is fixedly connected between the sliding block and the first baffle. A bracket is fixedly connected to the outside of the sliding rod. A locking shaft is fixedly connected inside the bracket. The locking shaft is slidably connected inside the first baffle and is locked inside the S-hook body. By driving the bracket to slide, it drives the locking shaft to slide.

[0006] Preferably, the first baffle has a groove at the corresponding position of the sliding block, and the sliding block slides in the groove.

[0007] Preferably, the S-hook body has a groove at the corresponding position of the retaining shaft, and the retaining shaft is engaged in the corresponding groove of the S-hook body.

[0008] Preferably, a limiting block is fixedly connected to the outer side of the S-hook body, a support frame is fixedly connected to the left end of the bracket, a lever is fixedly connected to the inner side of the support frame, and the lever is slidably connected inside the first baffle.

[0009] Preferably, there are two limiting blocks. One limiting block is vertically distributed at the right end of the first baffle, and the other limiting block is horizontally distributed at the bottom end of the first baffle. The first baffle has a groove at the corresponding position of the lever, and the lever slides in the groove.

[0010] Preferably, the rebound assembly includes a second optical axis, which is rotatably connected inside the S-hook body. A second baffle is fixedly connected to the outside of the second optical axis, and a torsion spring is fixedly connected between the second baffle and the S-hook body. A limit groove is formed inside the S-hook body.

[0011] Preferably, two torsion springs are provided, symmetrically distributed at both ends of the second baffle.

[0012] The beneficial effects of this utility model are as follows: Compared to the lack of a limiting device for the S-hook, by rotating the first baffle, the first baffle is fixed to the S-hook body through the locking pins on both sides, thereby limiting the end hanging on the catenary and preventing it from falling off. This effectively suspends the cable, improves the stability during suspension, increases the efficiency of the overhead contact line installation, enhances its practicality, and effectively prevents the S-hook body from falling off due to accidental contact by workers. It also avoids the problem that the catenary may easily fall off the S-hook due to shaking during suspension, thus preventing effective suspension. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 5This utility model provides an embodiment of an anti-detachment contact wire support S-hook device, including an S-hook body 1, a first optical axis 21, and a spring-loaded assembly. The spring-loaded assembly is internally located within the S-hook body 1. The first optical axis 21 is rotatably connected internally to the S-hook body 1. A first baffle 23 is fixedly connected externally to the first optical axis 21. A sliding rod 24 is slidably connected internally to the first baffle 23. A sliding block 25 is fixedly connected externally to the sliding rod 24. A spring 26 is fixedly connected between the sliding block 25 and the first baffle 23. A bracket 27 is fixedly connected externally to the sliding rod 24. A retaining shaft 28 is fixedly connected internally to the bracket 27. The retaining shaft 28 is slidably connected... Inside the first baffle 23, the locking pin 28 is engaged inside the S-hook body 1. By sliding the bracket 27, the locking pin 28 slides. Through the sliding rod 24 fixedly connected inside the bracket 27, the sliding block 25 slides inside the first baffle 23. The sliding block 25 compresses the springs 26 on both sides, causing the locking pins 28 to move away from the corresponding slots on the S-hook body 1, thus releasing them from engagement. The first baffle 23 is then flipped via the first optical axis 21, and the top of the S-hook body 1 is hung on the catenary. By rotating the first baffle 23, the locking pins are engaged... 28 slides outward, compressing the spring 26. When the first baffle 23 is blocked by the limiting block 22, the locking shaft 28 has moved to the corresponding position of the S-hook body 1. By releasing the lever 210, the elasticity of the spring 26 causes the locking shafts 28 on both sides to be limited, locking them into the corresponding grooves of the S-hook body 1. This fixes the first baffle 23 inside the S-hook body 1, preventing the S-hook body 1 from falling off when hanging on the catenary and effectively preventing the S-hook body 1 from falling off due to accidental contact. The rebound assembly inserts the wire from the lower end of the S-hook body 1 into the interior of the S-hook body 1, through the torsion spring. 33 causes the second baffle 32 to reset, making it easier to hook and lift the wire. The first baffle 23 has a groove at the corresponding position of the sliding block 25. The sliding block 25 slides in the groove. The groove limits the sliding block 25 and controls the sliding stroke of the sliding block 25, thereby improving the engagement efficiency of the two side retaining pins 28 and the stability of preventing detachment. The S-hook body 1 has a groove at the corresponding position of the retaining pin 28. The retaining pin 28 engages in the corresponding groove of the S-hook body 1. The groove allows the first baffle 23 to be fixed and unfixed to the S-hook body 1 according to the corresponding position of the two side retaining pins 28, thereby improving the anti-detachment efficiency and stability.

[0021] Please see Figure 2 - Figure 3In this embodiment, a limiting block 22 is fixedly connected to the outer side of the S-hook body 1, a support frame 29 is fixedly connected to the left end of the bracket 27, and a lever 210 is fixedly connected to the inner side of the support frame 29. The lever 210 is slidably connected inside the first baffle 23. The lever 210 facilitates the sliding of the two locking shafts 28, thereby improving the locking efficiency. Two limiting blocks 22 are provided. One limiting block 22 is vertically distributed at the right end of the first baffle 23, and the other limiting block 22 is horizontally distributed at the bottom end of the first baffle 23. The first baffle 23 has a groove at the corresponding position of the lever 210. The lever 210 slides in the groove. The two limiting blocks 22 limit the first baffle 23, allowing it to rotate only 90 degrees. The groove limits the lever 210, thereby improving the limiting efficiency and the locking stability.

[0022] Please see Figure 4 - Figure 5 In this embodiment, the rebound assembly includes a second optical axis 31, which is rotatably connected to the inside of the S-hook body 1. A second baffle 32 is fixedly connected to the outside of the second optical axis 31. A torsion spring 33 is fixedly connected between the second baffle 32 and the S-hook body 1. A limiting groove 34 is opened inside the S-hook body 1 to facilitate hooking and lifting the wire, thereby improving the hooking efficiency of the wire. Two torsion springs 33 are provided, which are symmetrically distributed at both ends of the second baffle 32. The torsion springs 33 on both sides improve the reset efficiency of the second baffle 32 and improve the hooking efficiency of the wire.

[0023] During operation, by moving the two levers 210 outward, they slide inside the first baffle 23, causing the support frame 29 to drive the brackets 27 on both sides to slide. The sliding rods 24 fixedly connected inside the brackets 27 drive the sliding blocks 25 to slide inside the first baffle 23. The sliding blocks 25 compress the springs 26 on both sides, causing the locking pins 28 on both sides to move away from the corresponding slots of the S-hook body 1, thus releasing them from the S-hook body 1. The first baffle 23 is then flipped via the first optical axis 21, and the two limiting blocks 22 limit its rotation to ninety degrees. The top of the S-hook body 1 is then hung on the catenary. Rotating the first baffle 23 causes the locking pins 28 to slide outward, compressing the springs 26. The first baffle 23 is then pushed into place by the limiting blocks 22. When the hook is blocked, the locking shaft 28 has moved to the corresponding position of the S-hook body 1. By releasing the lever 210, the elasticity of the spring 26 causes the locking shafts 28 on both sides to be limited, locking them into the corresponding grooves of the S-hook body 1. This fixes the first baffle 23 inside the S-hook body 1, preventing the S-hook body 1 from falling off the catenary and effectively preventing it from falling off due to accidental contact. By inserting the wire into the S-hook body 1 from the lower end, when the wire contacts the second baffle 32, it causes the second baffle 32 to rotate into the S-hook body 1 through the second optical axis 31. When the wire does not contact the second baffle 32, the torsion spring 33 causes the second baffle 32 to reset, returning it to the limiting groove 34. The limiting groove 34 prevents the second baffle 32 from rotating outward, thus limiting the second baffle 32 and improving the hooking efficiency of the wire.

[0024] Through the above steps, by rotating the first baffle 23, it is fixed to the S-hook body 1 by the locking pins 28 on both sides, thereby limiting the end hanging on the catenary and preventing it from falling off. This solves the problem that the catenary is easy to fall off the S-hook during the suspension process, thus making it impossible to suspend effectively.
