Detailed Description

The present invention will be further described with reference to the accompanying drawings, and it should be noted that the following embodiments are based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the embodiments.

A contact net wire breaking joint tool, as shown in fig. 1-5, comprising a first openable and closable contact wire clamp 1, a second openable and closable contact wire clamp 10, a main shaft 3 and a main shaft sleeve 4; the first openable and closable contact wire clamp 1 and the second openable and closable contact wire clamp 10 have the same structure and comprise two clamping plates 8 and a wire clamp fastener; one ends of the two clamping plates 8 are movably connected, and the other ends are locked and closed by a wire clamp fastener; after the two clamping plates 8 are closed, a cavity 9 with a shape matched with the shape of the section surface of the contact line is formed in the middle; one end of the main shaft 3 is fixedly connected with the first openable and closable contact wire clamp 1; one end of the main shaft sleeve 4 is fixedly connected with a second openable contact wire clamp 10; the spindle 3 can be inserted into a spindle sleeve 4.

Further, when the main shaft 3 is inserted into the main shaft sleeve 4, the central axes of the cavities 9 of the first openable and closable contact wire clamp and the second openable and closable contact wire clamp are on the same horizontal line, so that when two disconnected contact wire joints are respectively fixed in the cavities 9, the two disconnected contact wire joints are on the same horizontal line, the contact wire grooves can be simultaneously fixed in the joint wire clamps, and the situation that the connection of the contact wires is difficult to continue smoothly due to the fact that the contact wires are twisted when the contact wires are disconnected is avoided.

Further, as shown in fig. 1-3, the wire clamp fastener comprises a bolt 2 and a nut 11 matched with the bolt 2, one end of the bolt is hinged on one of the clamping plates, the other clamping plate is provided with a groove 12 matched with the bolt, the groove is positioned above the position of the cavity, when the contact wire is to be fixed, the contact wire is put into the cavity, the bolt 2 is rotated to enable the other end of the bolt to enter the groove, the nut 11 is screwed on the bolt, and the contact wire is fixed in the cavity between the two clamping plates. When the openable and closable contact wire clamp which is locked and closed needs to be opened, the nut 11 needs to be unscrewed, the bolt 2 arranged in the groove is lifted, the bolt 2 is rotated back to the original position, and then the two clamping plates can be opened, as shown in fig. 2.

Further, as shown in fig. 3, the first openable and closable contact line clamp 1 is fixedly connected to one end of the main shaft 3, and a cylindrical protrusion 5 is provided on the surface of the other end of the main shaft.

Further, as shown in fig. 4, a second openable and closable contact wire clamp 10 is fixedly connected to one end of the spindle sleeve 4, a groove 7 matched with the cylindrical protrusion 5 is axially formed on the surface of the other end of the spindle sleeve, and a circular platform 6 is disposed between the groove and the second openable and closable contact wire clamp 10.

Further, as shown in fig. 5, the spindle 3 and the spindle sleeve 4 are butted against each other. The main shaft 3 is inserted into the main shaft sleeve 4, and the bulge is inserted into the groove and can ensure that the middle shafts of the cavities 9 of the first openable contact wire clamp and the second openable contact wire clamp are positioned on the same horizontal line when moving along the groove, thereby playing a role of auxiliary positioning.

The working principle of the tool for connecting the broken line of the contact network is that, as shown in fig. 6, after a main shaft and a main shaft sleeve are mutually butted, a first openable and closable contact line clamp 1 and a second openable and closable contact line clamp 10 respectively fix two broken contact line joints, and ensure that the contact line faces downward when contacting with a pantograph, the contact line joint fixed on the second openable and closable contact line clamp 10 is positioned above a platform 6 of the main shaft sleeve 4, the position of the contact line to be fixed by the first openable and closable contact line clamp 1 is determined according to the field condition, so that the two broken contact line joints are butted on the premise that a bulge 5 is in a groove 7, the platform 6 on the main shaft sleeve 4 is used for placing the two contact line joints, and the contact line joint clamps are installed, so that the tool is convenient for operating by workers and improves the working efficiency.
