Abstract
Description
Technical Field
[0001] The invention relates to the technical field of circuit maintenance, and in particular to a contact wire disconnection joint assistant. Background Art
[0002] When the contact line of an electrified railway suddenly breaks under stress, the wires at both ends shrink and rebound instantly under the action of tension, and the contact line positioning devices will also be displaced. The two broken wires themselves will also bend and twist to varying degrees. When emergency rescue is carried out to connect the broken wires and tighten the two wires, if the tensioners fixing the two wires are not on the same horizontal plane, the two wires will also be twisted to varying degrees, with a large twist ranging from 30° to 120°. If inappropriate tools are used, the installation time of the auxiliary wire clamps at the contact line joints will inevitably be prolonged, which will inevitably affect the speed of rescue. It is imperative to innovate the supporting tools.
[0003] The work area units currently have clamp-type and slot-type twisters, as well as bow-type disconnected wire joint assistants. During the disconnected wire connection process of the overhead contact network, the two contact wires are severely twisted, causing the joint wire clamp to be unable to be installed normally. With the existing twister, one person cannot twist the surface and install the joint wire clamp at the same time, and the bow-type joint assistant takes a long time to install, which directly causes the installation time to exceed or the disconnected wire cannot be connected.
[0004] The invention provides a device which can effectively reduce the time for installing a joint wire clamp when a contact wire is disconnected and connected. Summary of the invention
[0005] The main purpose of the present invention is to provide a contact wire disconnection joint assistant so as to effectively solve the problems raised in the background technology.
[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical scheme: a contact line broken joint assistant, including a ratchet wrench, an electrical connection wire clamp, and a pull rod, the ratchet wrench including a left ratchet wrench and a right ratchet wrench, a two-way ratchet buckle is fixed in each of the two ratchet wrench bayonet sockets, a connecting rod is welded on the outer side of each, the other end of the connecting rod is a screw, an electrical connection wire clamp is screwed on the screw, the electrical connection wire clamp is provided with a clamping bolt for clamping the contact line, and a hollow tube perpendicular to the screw is welded and fixed on the electrical connection wire clamp.
[0007] Preferably, two insert tubes are welded in the middle of the handle of the left ratchet wrench 1, and two pins are welded in the middle of the handle of the right ratchet wrench. The positions of the pins correspond to the insert tubes, and the pins can be inserted into the insert tubes to fix the left ratchet wrench and the right ratchet wrench together.
[0008] Preferably, except the ratchet wrench, the remaining parts are all made of metal aluminum.
[0009] The beneficial effects of the present invention are as follows: 1. It is installed by combining two parts, and the two ends can be fixed separately and then combined, which is convenient for actual operation. 2. It is made of aluminum alloy, which is light and compact and easy to carry. 3. The contact wire is fixed by the electric connection wire clamp, which is not easy to damage the contact wire. 4. A single person can twist the surface with one hand and install the joint auxiliary wire clamp with the other hand. It is light and compact, easy to install. It is not easy to damage the contact wire, which is conducive to high-altitude on-site maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Attached Figure 1 In the middle, left ratchet wrench 1, right ratchet wrench 2, electrical connection wire clamp 3, screw rod 4, clamping bolt 5, hollow tube 6, pull rod 7, two-way ratchet buckle 8, insert tube 9, latch pin 10, contact wire 11. DETAILED DESCRIPTION
[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0013] Attached Figure 1 As shown in the figure, a contact line broken joint assistant includes a ratchet wrench, an electric connecting wire clamp, and a pull rod. The ratchet wrench includes a left ratchet wrench 1 and a right ratchet wrench 2. A two-way ratchet buckle 8 is welded and fixed in each of the two ratchet wrench bayonet sockets, and a pull rod 7 is welded on the outside of each of the two-way ratchet buckles 8. The other end of the pull rod 7 is a screw 4, and an electric connecting wire clamp 3 is screwed on the screw 4. The electric connecting wire clamp 3 is provided with a clamping bolt 5 for clamping the contact wire, and a hollow tube 6 perpendicular to the screw 4 is welded and fixed on the clamping bolt.
[0014] Preferably, two insert tubes 9 are welded in the middle of the handle of the left ratchet wrench 1, and two latches 10 are welded in the middle of the handle of the right ratchet wrench 2. The latches 10 correspond to the positions of the insert tubes 9, and the latches 10 can be inserted into the insert tubes to fix the left ratchet wrench 1 and the right ratchet wrench 2 together.
[0015] Preferably, except the ratchet wrench, the remaining parts are all made of metal aluminum.
[0016] When in use, first tighten the contact wire with a lever hoist, fix the contact wires 11 at both ends with the electrical connection wire clamps 3, shake the left and right ratchet wrenches to move the electrical connection wire clamps 3 on the screw rod 4 and approach the middle, then use a screwdriver or its metal stick to insert the hollow tube 6, twist the grooves of the contact wires at both ends to the same plane, and connect them with special tools.
