Description

Catenary repair clamping device {a device for clamping with repair of catenary}

The present invention is for repairing the tank line to replace the part of the damaged tank line due to uneven wear and the like to fix the connection portion of the tank line in the state of positioning by the clamp when installing a new tank line, so that the maintenance and repair work of the tank line can be performed quickly It relates to a clamping device.

In general, the electric railway has played a pivotal role in the overall industry such as logistics as well as urban transportation due to many advantages such as speed, accuracy, stability, mass transport, comfort, and low pollution compared to other transportation methods.

The electric vehicle used in the electric railway is driven by the applied voltage. The electric vehicle is fixed to the T-BAR in the section in which the electric vehicle is driven, and the electric vehicle is operated by the contact with the pantograph of the electric vehicle. The power is continuously supplied during the process.

Since the catenary is in contact with the current collector for a long time, grooves or local wear occurs, and due to the expansion and contraction action of the catenary due to the temperature change of the catenary, the catenary is stretched due to the increase of the catenary, or the power supply is cut off due to a breakage in the catenary. do.

If the groove or local wear phenomenon continues as described above, the tram line is cut off due to the occurrence of arcs caused by the two-line phenomenon. At this time, some sections of the abrasion tank line are cut off and the new tram line is sharpened or cut off. It reinforces the tank line without making a wire.

The sharp wire, that is, the auxiliary tram line, is to reinforce the broken or severely worn part of the main tram line. In order to improve the maintainability of the vehicle, the connection part of the catenary must be made simple and solid.

In connection with such a technology, the applicant of the present invention has proposed a catenary connection apparatus in Registration Utility Model No. 386180, and the configuration thereof is shown in FIGS. 1 and 2, wherein the connection apparatus 1000 includes the first, The two fixing members 110 and 120 are coupled to the tee 800 on the ceiling of the underground section of the subway, and the main clamps fixing the main tram line 600, and the third and fourth fixing members 210 and 220, respectively. Auxiliary clamp, bolt 300, the first, second washer (400, 400-1) and the nut (500) formed by coupling is a basic component.

One side surface of the first fixing member 110 is formed as a flat surface for supporting the first washer 400 penetrated through the bolt 300, and the other side surface supports and supports the lower end of the T-bar at the upper side and the lower side. First and second fixing jaws 112 and 114 to be fixed are formed, and in the lower end, in order to be fixed to and support the main tram line 600, to be caught in the groove 610 of the upper side of the main tram line 600. The jaw 116 bent by a predetermined angle is formed.

In addition, the second fixing member 120 is to be coupled to the other side of the first fixing member 110, one side is provided at a position corresponding to the first fixing member 110, the upper side and the lower side Third and fourth fixing jaws 122 and 124 are formed to support and fix the lower end of the lower end, and the lower end is in contact with the recessed groove 610 to be coupled to the recessed groove 610 of the upper side of the main tram line 600. The bite jaw 126 is bent to the inside by a predetermined angle is formed.

In addition, the other side surface of the second fixing member 120 is formed of a screw thread 129 and is screwed with the screw thread 219 of one side of the third fixing member 210 to be described later, and the first fixing member 110. ) And the second fixing member 120 are coupled as described above, and the through hole 808 of the T-bar 800 is inserted between the first fixing member 110 and the second fixing member 120 to be fixed to the ceiling. do.

When the main tank line 600 of the main clamp 100 coupled as described above is broken or damaged, the sub-clamp 200 for electrically coupling the auxiliary tank line 700, which is an additional portion thereof, with the main clamp 100 in parallel. ) Is composed of the combination of the third fixing member 210 and the fourth fixing member 220.

However, the connection device as described above, when the secondary tank line 700 is not fixed continuously, if the bending of the tank line, etc. requires a separate work to unfold it, workability is reduced, the auxiliary tank line when the train is running When the 700 is deformed, the reliability of the power supply is lowered, and only a part of the auxiliary tank lines 700 are supported as the auxiliary clamps 200, thereby making it difficult to secure the coupling.

In addition, the need for a separate fixing device for supporting the end of the auxiliary tank line 700 and the main tank line 600, respectively, there is a residual point that the number of parts and the work process increases.

An object of the present invention for improving the conventional problems as described above, to ensure that the maintenance and repair work of the tramline can be made quickly and accurately, to secure and secure the tramline, and to prevent uneven wear and connection failure of the tramline It is possible to reduce the cost by mass production, as well as to be used repeatedly, and to provide a clamping device for repair of the tank line to enable positioning when combined without correction of the tank line.

In order to achieve the above object of the present invention, one side end or another side end of the tank line is shorted while being connected to the upper end of the T bar through the T bar clamps are arranged on both sides of the T bar to be fixed to both sides of the T bar, respectively. Composed of a plurality of clamp combinations,

The clamp is provided to the upper end of the T-bar while providing a mounting space in which the tank line is inserted, providing a clamping device for repairing the tank line made of a configuration that is integrally provided with a locking jaw corresponding to the tight groove of the tank line.
