Description

Technical Field

[0001] This application generally relates to the field of traction power supply technology for electrified railways, and specifically to terminal anchor clamps for steel structures. Background Technology

[0002] The rapid development of electrified railways has brought formidable challenges to improving the safe and stable operation of traction power supply systems. The overhead contact system is a crucial component of traction power supply equipment, responsible for the uninterrupted transmission of electrical energy to electric locomotives operating along the line, and is a vital guarantee for the safe and reliable operation of electrified railways.

[0003] Conventional power lines are wrapped inside anchor clamps. When the conductor is under tension, it will gradually slide out of the anchor clamp. Since the conductor is completely wrapped inside the anchor clamp, it is impossible to observe the sliding of the conductor, which makes maintenance difficult. The conductor may also fall out of the anchor clamp completely, which can cause safety accidents. Utility Model Content

[0004] To allow for direct observation of the sliding of one end of the conductor on the anchor clamp, this application provides a steel structure terminal anchor clamp that allows one end of the conductor to be extended and installed on the anchor clamp. The extended conductor can be slid through, allowing for direct observation of the conductor's sliding on the anchor clamp.

[0005] According to one aspect of this application, a terminal anchoring clamp for a steel structure is provided, the terminal anchoring clamp including a U-shaped clamp; and a wedge assembly disposed within the opening of the U-shaped clamp; wherein a conductor passes through the bottom surface of the U-shaped clamp and is connected to the wedge assembly; wherein one end of the conductor near the wedge assembly extends out of the wedge assembly; and a bolt passes through both ends of the opening of the U-shaped clamp, the bolt located within the opening of the U-shaped clamp being connected to an anchor.

[0006] In some embodiments, the U-shaped clamp includes: a base plate; and two sets of side plates, one end of which is connected to the two end faces of the base plate; wherein the two side plates and the base plate form a U-shaped structure, and the opening of the U-shaped structure is used to set a wedge assembly; mounting holes are provided on the surface of the base plate, and wires are passed through the mounting holes; and two sets of through holes are provided, each set being provided on the surface of one end of the two side plates away from the base plate; wherein bolts pass through the two through holes.

[0007] In some embodiments, the wedge assembly includes: a wedge sleeve, one end of which is connected to the base plate near the side plate, and the axis of the wedge sleeve passes through the center of the mounting hole; a positioning wedge, disposed at the end of the wedge sleeve away from the base plate; wherein a wire passes through the mounting hole and the wedge sleeve and is connected to the positioning wedge, and the end of the wire near the positioning wedge extends out of the end face of the positioning wedge.

[0008] In some embodiments, the wedge assembly further includes: a tapered anchor fitted onto the outer wall of the guide wire extending from the positioning wedge; wherein the tapered anchor is spaced apart from the positioning wedge, the smaller diameter end of the tapered anchor faces the positioning wedge, and the tapered anchor cooperates with an adjustment device.

[0009] In some embodiments, the adjusting device includes: a first S-shaped plate and a second S-shaped plate, the first S-shaped plate and the second S-shaped plate being hinged at their middle sections; wherein the two ends of the first S-shaped plate are a mating end and a movable end, respectively, the mating end being used to engage a limiting groove; wherein the limiting groove is disposed on the sidewall of the two side plates, the limiting groove being disposed between the positioning wedge and the bolt; and a tapered hole, disposed on the surface of the second S-shaped plate, the tapered hole being disposed on the end of the second S-shaped plate near the mating end of the first S-shaped plate, the large-diameter end of the tapered hole being disposed towards the first S-shaped plate, the tapered hole being used to engage a tapered anchor.

[0010] In some embodiments, one side of the tapered aperture is open.

[0011] In some embodiments, a first traction hole is provided on the movable end surface of the first S-shaped plate, and a second traction hole is provided on the end surface of the second S-shaped plate away from the tapered hole. The second traction hole is used to cooperate with the telescopic end of the hydraulic telescopic rod, and the first traction hole is used to cooperate with the mounting end of the hydraulic telescopic rod. The hydraulic telescopic rod is used to adjust the distance between the movable end of the first S-shaped plate and the second S-shaped plate.

[0012] The embodiments of this application have the following advantages. In use, one end of the conductor is passed through the bottom surface of the U-shaped clamp and through the wedge assembly. When the conductor is lifted, it is affected by tension, and the conductor pulls the wedge assembly, causing the wedge assembly to tighten and fix one end of the conductor. One end of the conductor needs to extend out of the end face of the wedge assembly, so that after the anchor clamp has been used for a long time, the conductor will slide outward from the wedge assembly under the influence of gravity. The sliding of the conductor can be directly observed through the extended conductor. In traditional methods, the conductor is completely wrapped by the terminal anchor clamp, so the sliding of the conductor cannot be observed from the outside. If the conductor is not re-tensioned in time, it is easy for the conductor to completely fall off the anchor clamp, causing a safety accident.

[0013] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0030] To make the objectives, solutions, and advantages of the technical solutions of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] As described above, in the use of traditional anchor clamps, since one end of the conductor is completely wrapped by the anchor clamp, it is impossible to observe the sliding of the conductor inside the anchor clamp.

[0033] To at least partially address one or more of the aforementioned problems and other potential issues, an example embodiment of this application provides a terminal anchoring clamp for a steel structure. The anchoring clamp includes a U-shaped clamp and a wedge assembly disposed within the opening of the U-shaped clamp. A conductor passes through the bottom surface of the U-shaped clamp and connects to the wedge assembly. One end of the conductor near the wedge assembly extends out of the wedge assembly. A bolt passes through both ends of the opening of the U-shaped clamp, and the bolt located within the opening of the U-shaped clamp is connected to the anchor. This allows for direct observation of the conductor's sliding within the wedge assembly via the extended conductor, enabling timely repositioning and installation of the conductor and preventing complete detachment from the wedge assembly.

[0034] The following description, in conjunction with the accompanying drawings, exemplarily illustrates the terminal anchoring clamps of the steel structure in embodiments of this application. Figure 1 A schematic diagram of a U-shaped clamp structure according to an embodiment of this application is shown. Figure 2 A schematic diagram of a pin installation according to an embodiment of this application is shown. Figure 3 A schematic diagram of a wedge assembly structure according to an embodiment of this application is shown.

[0035] A steel structure terminal anchor clamp includes: a U-shaped clamp; and a wedge assembly 2 disposed in the opening of the U-shaped clamp; wherein a conductor 3 passes through the bottom surface of the U-shaped clamp and is connected to the wedge assembly 2; wherein one end of the conductor 3 near the wedge assembly 2 extends out of the wedge assembly 2; and a bolt 4 passes through both ends of the opening of the U-shaped clamp, and the bolt 4 located in the opening of the U-shaped clamp is connected to the anchor.

[0036] In use, one end of the wire 3 is passed through the bottom surface of the U-shaped clamp and through the wedge assembly 2. When the wire 3 is lifted, it is affected by tension and pulls the wedge assembly 2, causing the wedge assembly 2 to tighten and fix one end of the wire 3.

[0037] It is worth noting that one end of the conductor 3 needs to extend beyond the end face of the wedge assembly 2. This allows the conductor 3 to slide outward from the wedge assembly 2 under the influence of gravity after prolonged use of the anchor clamp. The sliding of the conductor 3 can be directly observed through the extended conductor 3. In the traditional case, the conductor 3 is completely wrapped by the terminal anchor clamp, making it impossible to observe the conductor 3 after it slides. If the conductor 3 is not re-tensioned in time, it is easy for the conductor 3 to completely fall off the anchor clamp, causing a safety accident.

Figure 2 A schematic diagram of a pin installation according to an embodiment of this application is shown. Figure 3 A schematic diagram of a wedge assembly structure according to an embodiment of this application is shown.

[0039] In some embodiments, the U-shaped clamp includes: a base plate 11; and two sets of side plates 12, one end of which is connected to the two end faces of the base plate 11; wherein the two side plates 12 and the base plate 11 form a U-shaped structure, and the opening of the U-shaped structure is used to set the wedge assembly 2; mounting holes 13 are provided on the surface of the base plate 11, and the wire 3 passes through the mounting holes 13; and two sets of through holes 14 are provided, the two sets of through holes 14 are respectively provided on the surface of the two side plates 12 away from the base plate 11; wherein the bolt 4 passes through the two through holes 14.

[0040] In use, the base plate 11 is provided with mounting holes 13 for the wire 3 to pass through and connect to the wedge assembly 2. After the wire 3 is fixed by the wedge assembly 2, the bolt 4 is passed through the two through holes 14 and fixed to the nut. Then the bolt 4 body is connected to the anchor.

[0041] Figure 1 A schematic diagram of a U-shaped clamp structure according to an embodiment of this application is shown. Figure 2 A schematic diagram of a pin installation according to an embodiment of this application is shown. Figure 3 A schematic diagram of a wedge assembly structure according to an embodiment of this application is shown.

[0042] In some embodiments, the wedge assembly 2 includes: a wedge sleeve 21, one end of which is connected to the side of the base plate 11 near the side plate 12, and the axis of the wedge sleeve 21 passes through the center of the mounting hole 13; a positioning wedge 22, which is disposed at the end of the wedge sleeve 21 away from the base plate 11; wherein a wire 3 passes through the mounting hole 13 and the wedge sleeve 21 and is connected to the positioning wedge 22, and the end of the wire 3 near the positioning wedge 22 extends out of the end face of the positioning wedge 22.

[0043] In use, after the wire 3 passes through the mounting hole 13 and the wedge sleeve 21, the wire 3 passes through the positioning wedge 22 and extends out of the positioning wedge 22. Under the influence of gravity, the wire 3 drags the positioning wedge 22 towards the wedge sleeve 21 and embeds the positioning wedge 22 into the wedge sleeve 21. The positioning wedge 22 moves along the inner wall of the wedge sleeve 21. One end of the inner wall of the wedge sleeve 21 is a large diameter end and the other end is a small diameter end. The small diameter end of the positioning wedge 22 enters from the large diameter end of the wedge sleeve 21 and moves towards the small diameter end of the wedge sleeve 21. The positioning wedge 22 is tightened by the inner wall of the wedge sleeve 21 until the positioning wedge 22 clamps the wire 3.

[0044] It is worth noting that when the wire 3 is affected by gravity and one end of the wire 3 near the positioning wedge 22 falls off the positioning wedge 22, the distance the wire 3 moves on the positioning wedge 22 can be directly observed because the wire 3 extends out of the end face of the positioning wedge 22. This helps maintenance personnel to quickly determine whether the wire 3 needs to be reinforced again.

Figure 2 A schematic diagram of a pin installation according to an embodiment of this application is shown. Figure 3 A schematic diagram of a wedge assembly structure according to an embodiment of this application is shown.

[0046] In some embodiments, the wedge assembly 2 further includes a tapered anchor 23, which is sleeved on the outer wall of the guide wire 3 extending from the positioning wedge 22; wherein the tapered anchor 23 is spaced apart from the positioning wedge 22, the small diameter end of the tapered anchor 23 faces the positioning wedge 22, and the tapered anchor 23 cooperates with the adjustment device 5.

[0047] In use, the tapered anchor 23 is set at one end of the guide wire 3 near the positioning wedge 22. When the guide wire 3 slides a certain distance in the positioning wedge 22, the tapered anchor 23 abuts against one end of the positioning wedge 22. If the guide wire 3 continues to move, the tapered anchor 23 tightens to fix the guide wire 3, preventing the guide wire 3 from sliding too much and falling off the positioning wedge 22.

Figure 2 A schematic diagram of a pin installation according to an embodiment of this application is shown. Figure 3 A schematic diagram of a wedge assembly structure according to an embodiment of this application is shown. Figure 4 A schematic diagram of the adjustment component structure according to an embodiment of this application is shown. Figure 5 A schematic diagram of a first S-shaped plate structure according to an embodiment of this application is shown. Figure 6 A schematic diagram of a second S-shaped plate structure according to an embodiment of this application is shown.

[0049] In some embodiments, the adjusting device 5 includes: a first S-shaped plate 51 and a second S-shaped plate 52, the first S-shaped plate 51 and the second S-shaped plate 52 being hinged at the middle section; wherein the two ends of the first S-shaped plate 51 are a mating end 53 and a movable end 54, respectively, the mating end 53 being used to engage a limiting groove 55; wherein the limiting groove 55 is disposed on the side wall of the two side plates 12, the limiting groove 55 being disposed between the positioning wedge 22 and the bolt 4; and a tapered hole 56, disposed on the surface of the second S-shaped plate 52, the tapered hole 56 being disposed on the end of the second S-shaped plate 52 near the mating end 53 of the first S-shaped plate 51, the large diameter end of the tapered hole 56 being disposed towards the first S-shaped plate 51, and the tapered hole 56 being used to engage a tapered anchor 23.

[0050] The tapered hole 56 is open on one side.

[0051] The surface of the movable end 54 of the first S-shaped plate 51 is provided with a first pulling hole 57, and the surface of the end of the second S-shaped plate 52 away from the tapered hole 56 is provided with a second pulling hole 58. The second pulling hole 58 is used to cooperate with the telescopic end of the hydraulic telescopic rod 59, and the first pulling hole 57 is used to cooperate with the mounting end of the hydraulic telescopic rod 59. The hydraulic telescopic rod 59 is used to adjust the distance between the movable end 54 of the first S-shaped plate 51 and the second S-shaped plate 52.

[0052] Both sets of side plates 12 are provided with pins on their surfaces, and the pins are located at the end of the wedge sleeve 21 near the bolt 4.

[0053] During use, observe the movement distance of the conductor 3. When it is necessary to reinforce the conductor 3, insert the mating end 53 of the first S-shaped plate 51 of the adjusting device 5 into the limiting groove 55, and insert the conical hole 56 of the second S-shaped plate 52 into the conductor 3 from the end of the conical anchor 23 near the positioning wedge 22, so that the small diameter end of the conical anchor 23 is inserted into the conical hole 56. Then, pass one end of the hydraulic telescopic rod 59 through the first pull hole 57 of the first S-shaped plate 51 and the second pull hole 58 of the second S-shaped plate 52, fix the end of the hydraulic telescopic rod 59 extending out of the second pull hole 58, set the mounting end of the hydraulic telescopic rod 59 on the side of the first pull hole 57, start the hydraulic telescopic rod 59 to retract, so that the hydraulic The telescopic end of the telescopic rod 59 pulls the second S-shaped plate 52 toward the first S-shaped plate 51. At this time, the mating end 53 of the first S-shaped plate 51 moves toward the second S-shaped plate 52. The second S-shaped plate 52 drags the conical anchor 23 toward the bolt 4, causing the conical anchor 23 to retract and drive the wire 3 to move toward the bolt 4. At this time, the positioning wedge 22 falls out of the wedge sleeve 21. When the wire 3 moves to the designated position, the positioning wedge 22 is put back into the wedge sleeve 21. At this time, the hydraulic telescopic rod 59 is reset. The wire 3 is affected by gravity and embeds the positioning wedge 22 into the wedge sleeve 21 for repositioning and installation. The pin is used to prevent the wedge sleeve 21 and the positioning wedge 22 from falling out of the opening of the U-shaped clamp when installing the wedge sleeve 21 and the positioning wedge 22.
