Technical Field
[0001] The utility model relates to the technical field of broken wire connection, in particular to a double-tooth joint wire clamp for wire reinforcement. Background Art
[0002] At present, when emergency repair is carried out on the connection of copper and copper-silver alloy contact wires for railways, the purpose of temporary wiring cannot be achieved. This makes the disconnected line unable to be used normally during emergency repair, which has a great impact on the normal operation of railways. Content of the Utility Model
[0003] To solve the above problems, that is, the current lack of a device capable of broken wire connection, the utility model proposes a double-tooth joint wire clamp for wire reinforcement, which includes two wire clamping plates. One side surface of the wire clamping plate is provided with groove teeth, and the groove teeth on the two wire clamping plates are arranged oppositely. A corresponding number of through holes are also opened on the two wire clamping plates, bolts are inserted into the through holes, nuts are threadedly connected to the bolts, and the two wire clamping plates are arranged between the nuts and the nuts of the bolts.
[0004] The further setting of the utility model is that each wire clamping plate is provided with two groove teeth, and the two groove teeth are respectively arranged on two long sides of one side surface of the wire clamping plate.
[0005] The further setting of the utility model is that a flat washer is arranged between the nut and the wire clamping plate, and a spring washer is arranged between the nut of the bolt and the wire clamping plate.
[0006] The beneficial effect of the utility model is:
[0007] By using bolts and nuts, the purpose of clamping two wire clamping plates can be achieved, so that the groove teeth on the two wire clamping plates can clamp two metal wires to be connected. Further, the two ends of the two metal wires are brought into contact connection to achieve the purpose of temporary connection or emergency repair connection, ensuring that the line can be temporarily used.

[0011] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.
[0012] The present utility model provides a double-tooth joint wire clamp for wire reinforcement, which includes two wire clamping plates 1. On one side surface of the wire clamping plate 1, a groove tooth 11 is provided, and the groove tooth 11 is used for clamping the metal wire. The side surfaces of the two wire clamping plates 1 where the groove teeth 11 are provided are arranged oppositely, so that the groove teeth 11 on the two wire clamping plates 1 cooperate with each other to clamp the metal wire.
[0013] Corresponding through holes are also provided on the two wire clamping plates 1. Each wire clamping plate 1 is provided with eight through holes, and the eight through holes are symmetrically arranged about the midline of the long side of the wire clamping plate 1. A bolt 2 is commonly inserted into the two corresponding through holes on the two wire clamping plates 1, and a nut 3 is threadedly connected to the bolt 2. The two wire clamping plates 1 are arranged between the nut 3 and the nut of the bolt 2. Then, by screwing the nut 3, the distance between the two wire clamping plates 1 is adjusted, and further the purpose of clamping the metal wire is achieved.
[0014] Each clamping plate is provided with two groove teeth 11, and the two groove teeth 11 are respectively arranged on the two long sides of one side surface of the wire clamping plate 1, and further, it can simultaneously clamp two metal wires to be connected.
[0015] A flat washer 4 is sleeved between the nut 3 and the wire clamping plate 1, and a spring washer 5 is sleeved between the nut of the bolt 2 and the wire clamping plate 1.
[0016] The maximum working load of the device in this application is 33 KN, the tensile failure load is not less than 99 KN, the sliding load between copper-magnesium alloy metal wires is not less than 45 KN, and the sliding load between the wire clamping plate 1 and other metal wires (copper-tin alloy, copper-silver alloy) is within 95% of the nominal breaking force of the connected metal wire. The metal wire does not slip out of the wire clamping plate 1 and does not break inside the wire clamping plate 1 and at the wire clamp port. The wire clamping plate 1 is made of CuNi2Si material.
[0017] It should be noted that the cross-section of the metal wire used in railways is a circle with two conical notches, so the shape of the groove tooth 11 in this application is set to be adapted to the two conical notches of the metal wire.
[0018] Usage process:
[0019] First, check whether the parts are complete according to the installation schematic diagram or the parts list in the assembly drawing; check whether the parts have quality defects or deformation problems, and whether the cooperation between the fastening bolt 2 and the nut 3 is flexible.
[0020] Secondly, saw off the ends of the metal wires to be joined of the two broken wires flush. Then, loosen the nut 3 appropriately, insert the two ends of the two metal wires into the slot teeth 11 at both ends of the wire clamp 1 respectively. The inserted lengths are the same. Clamp the connecting wires in the lower slot teeth 11 and make the ends of the two connecting wires contact each other. Then, place the balancing wire into the upper slot teeth 11 from above. Tighten the bolts 2 in sequence. The balancing wire can balance the acting force when the wire clamp 1 is tightened.
[0021] Finally, use a torque wrench to tighten the bolts 2 from the middle to both ends of the wire clamp 1 in sequence to complete the joining work.
[0022] In summary, the present utility model can achieve the purpose of clamping the two wire clamps 1 by using the bolts 2 and nuts 3, so that the slot teeth 1 on the two wire clamps 1 can clamp the two metal wires to be joined. Further, the two ends of the two metal wires are brought into contact connection to achieve the purpose of temporary joining or emergency repair joining, ensuring that the line can be used temporarily.
