[0018] One embodiment of the present application, as shown in Figure 1 and Figure 2 A wire slot installation structure of a heat treatment furnace 30, comprising: a drag chain 11, a bracket, a roller assembly 10 and a strip-shaped groove 13; the drag chain 11 is a bendable structure, and a tubular cavity structure for threading a wire is arranged inside; the drag chain 11 is a common threading drag chain 11 product in the prior art. The top of the bracket is horizontally provided with a support beam 12 along the left-to-right direction; the right side of the bracket is horizontally provided with a strip-shaped groove 13 along the left-to-right direction, and the strip-shaped groove 13 and the support beam 12 are located in the same vertical plane, and the strip-shaped groove 13 is located below the support beam 12; the roller assembly 10 is horizontally arranged above the support beam 12 perpendicular to the extension direction of the support beam 12; the right end of the drag chain 11 is fixedly installed in the strip-shaped groove 13, the left end of the drag chain 11 is first extended to the right end of the strip-shaped groove 13 and then bent by 180 degrees to the left end, horizontally passes through the supporting surface of the roller assembly 10 and is then extended to the outside of the left end of the support beam 12 and connected with the heat treatment furnace 30; so that the drag chain 11 is bent and extended in a U shape from the strip-shaped groove 13 to above the support beam.

[0019] The drag chain 11 of the wire slot installation structure plays a wrapping protection role on the wire, the support structure composed of the bracket and the roller assembly 10 can support the drag chain 11 after threading the wire, and when the heat treatment furnace 30 drives the drag chain 11 to move, the bottom of the drag chain 11 can roll on the roller assembly 10, so that the drag chain 11 after threading the wire will not be suspended and pulled to be damaged, the power supply wire layout of the heat treatment furnace 30 is more reasonable, the structure is more stable, and the service life of the wire is longer.

[0020] Specifically, the roller assembly 10 comprises a support roller 14, a rotating shaft and a mounting base 15; the inner end and the outer end of the mounting base 15 are provided with rotating shaft holes; the two ends of the rotating shaft are respectively rotatably installed in the rotating shaft holes, the support roller 14 is rotatably sleeved on the outside of the rotating shaft, and the support roller 14 is horizontally arranged along the inner and outer directions; when the drag chain 11 extends to the support beam 12, the support roller 14 supports the bottom of the drag chain 11.

[0021] Preferably, the inner end and the outer end of the mounting base 15 are also provided with limiting protrusions 16; the drag chain 11 passes through the area between the two limiting protrusions 16 of the mounting base 15. So that the drag chain 11 can only move in the area between the two limiting protrusions 16, that is, the support roller 14 can always stably support the bottom of the drag chain 11, maintaining the structural stability of the wire slot mounting structure.

[0022] Preferably, the roller assembly 10 is provided with at least two, and the roller assemblies 10 are installed in the upper part of the support beam 12 at intervals. Multiple roller assemblies 10 can provide more point supports for the drag chain 11 after the wires are passed through, so that the drag chain 11 can extend to the position where the heat treatment furnace 30 is located in a nearly straight line state close to horizontal, which can further reduce the situation that the drag chain 11 is suspended and pulled.

[0023] Specifically, the roller assembly 10 has two, which are respectively installed above the left end and the right end of the support beam 12.

[0024] Preferably, the support frame comprises a left vertical column 17, a right vertical column 18 and a support rod; the support beam 12 is horizontally installed on the top of the left vertical column 17, one end of the support rod is fixedly connected with the bottom of the support beam 12, and the other end of the support rod is fixedly connected with the left vertical column 17.

Because the length of the drag chain 11 and the wire is fixed after installation, if the drag chain 11 needs to be pulled too much when the heat treatment furnace 30 is operated, the height difference between the support cross beam 12 and the strip-shaped groove 13 can be adjusted according to actual needs, so as to adjust the pulling movement allowance of the drag chain 11, which can greatly facilitate the daily use and operation of the heat treatment furnace 30, and is convenient for installation and maintenance of the wire slot structure.

[0026] Preferably, the right side column 18 is provided with a wire passing cavity, the bottom of the strip-shaped groove 13 is provided with a wire tube 22, and external wires are sequentially passed through the wire passing cavity of the right side column 18, the wire tube 22 and the tubular cavity structure of the drag chain 11, and then connected with circuits in the heat treatment furnace 30.
