Description

Technical Field

[0002] A heat treatment solid melting furnace is an industrial furnace used for heat treatment of materials, mainly applied to the solution treatment of metal materials. Its principle is to heat the metal material to a certain temperature through electric heating, gas heating or induction heating, etc., so that alloying elements are fully dissolved in the matrix metal, and then fix this tissue state through rapid cooling (quenching) to achieve the purpose of improving material properties.

[0003] A climbing ladder is one of the external structures on the solid melting furnace, mainly used to provide a convenient passage for operators to get on and off the furnace body, so that operators can easily reach the top of the solid melting furnace for regular maintenance inspection and emergency repair of the solid melting furnace.

[0004] Traditional solid melting furnace climbing ladders are mostly vertical ladders with cage structures, usually fixed by welding. However, since the outside of the solid melting furnace is not a flat structure, the contact area between the climbing ladder and the solid melting furnace is limited.

One end of the main support 412 is rotatably connected to the outer side wall of one second stud 411. An adjusting nut 414 is rotatably connected to the other end of the main support 412. One end of an adjusting screw 413 is connected to the inner side wall of the main support 412. The inner side wall of the adjusting nut 414 is threadedly connected to the outer side wall of the adjusting screw 413. A clamping block 415 is hinged to the other end of the adjusting screw 413. A sliding groove 416 is formed in the outer side of the main support 412. One end of a sub-support 417 is rotatably connected to the outer side wall of the other second stud 411. A third stud 418 is fixedly connected to the other end of the sub-support 417. The outer side wall of the third stud 418 is slidably connected to the inner side wall of the sliding groove 416. Nuts are threadedly connected to both ends of the two second studs 411 and the third stud 418.

[0057] By moving the first side puller 401, the main support 412 and the sub-support 417 are respectively sleeved on the two second studs 411 of the outer support frame 201. Then, by rotating the adjusting nut 414, the adjusting screw 413 is driven to move by the thread, and the overall length of the adjusting screw 413 and the main support 412 is adjusted according to actual needs, so that the clamping block 415 can be smoothly buckled on the heat treatment solid melting furnace body 101.

[0058] In one embodiment, the clamping block 415 of the first side puller 401 is clamped to the outer side wall of the heat treatment solid melting furnace body 101. One end of a fixing bolt 419 passes through the inner side walls of the clamping block 415 and the heat treatment solid melting furnace body 101 and is threadedly connected to the bottom of the inner side wall of the clamping block 415. The fixing bolt 419 of the second side puller 402 is fixedly connected to the upper surface of the heat treatment solid melting furnace body 101.

The fixing bolt 419 uses threads to cooperate with nuts to fixedly connect the clamping block 415 to the upper surface of the heat treatment solid melting furnace body 101.

[0059] By using the first side puller 401 to laterally pull and support the middle part of the vertical ladder 102, and the second side puller 402 is fixed between the cage reinforcement mechanism 2 and the heat treatment solid melting furnace body 101 in an inverted manner to laterally pull and support the top of the vertical ladder 102.

[0060] In one embodiment, a fence 51 is fixedly connected to the top of the heat treatment solid melting furnace body 101. A plurality of ladder fixing blocks 52 are symmetrically and fixedly connected to one side of the vertical ladder 102.

[0061] The vertical ladder 102 is installed and fixed by using the provided ladder fixing blocks 52 to penetrate the heat treatment solid melting furnace body 101 through bolts.

[0062] When the present invention is in operation: By rotating the internal thread sleeve 302, the connecting screw 301 is driven to move by the thread. The moving connecting screw 301 drives the outer support frame 201 to move, so as to adjust the distance between the outer support frames 201 according to the spacing of the protection cage frame 103. The spring 304 provided is gradually reset during the reverse movement of the connecting screw 301, so as to provide a reverse thrust between the two connecting screws 301 by using the spring 304 to ensure the stability of the movement of the connecting screw 301 within the internal thread sleeve 302.

[0063] After the distance between the outer support frames 201 is adjusted, by moving the inner support frame 202, the protection cage frame 103 is inserted into the inside of the inner support frame 202 by using the protection cage slot 203. Then, the outer support frame 201 is moved to drive the first stud 204 to penetrate through the inner support frame 202, so as to fix the outer support frame 201 and the inner support frame 202 by using bolts in cooperation with the first stud 204. Furthermore, the outer support frame 201 and the inner support frame 202 are assembled on the protection cage frame 103. Then, the outer support frame 201 and the vertical climbing ladder 102 are fixed by using bolts or welding, so as to increase the connection strength between the vertical climbing ladder 102 and the protection cage frame 103 by using the protection cage reinforcement mechanism 2.

[0064] After the protection cage reinforcement mechanism 2 is installed, by moving the first side pull frame 401, the main support 412 and the sub - support 417 are respectively sleeved on the two second studs 411 of the outer support frame 201. Then, by rotating the adjusting nut 414, the adjusting screw 413 is driven to move by the thread, and the overall length of the adjusting screw 413 and the main support 412 is adjusted according to actual needs, so that the block 415 can be smoothly buckled on the heat treatment solid melting furnace body 101. After the block 415 is buckled, by using the fixing bolt 419 to penetrate through the block 415 and the heat treatment solid melting furnace body 101, and connecting with the bottom of the inner side wall of the block 415 by using the thread in a rotating manner, so as to fix the block 415 on the heat treatment solid melting furnace body 101. Then, by reversely rotating the adjusting nut 414, the adjusting screw 413 and the main support 412 are tightened, ensuring that the side pull strengthening mechanism 4 can effectively provide side pull support for the vertical climbing ladder 102. The sliding groove 416 is provided so that when the main support 412 is adjusted in position, the third stud 418 slides in the sliding groove 416 to compensate between the main support 412 and the sub - support 417; after the tightening is completed, the main support 412 and the sub - support 417 are limited by the second stud 411 in cooperation with the nut, and the sub - support 417 and the main support 412 are fixed by the third stud 418 in cooperation with the nut.

[0065] After the first side puller 401 is installed, fix the fixing bolt 419 of the second side puller 402 on the upper surface of the heat treatment solid melting furnace body 101, and then repeat the above operation to fix the second side puller 402 upside down between the cage reinforcement mechanism 2 and the heat treatment solid melting furnace body 101 for lateral pulling support of the top of the vertical ladder 102. After the second side puller 402 is installed, fix the clamping block 415 on the upper surface of the heat treatment solid melting furnace body 101 by using the fixing bolt 419 in cooperation with the nut.

[0066] The vertical ladder 102 is installed and fixed by passing bolts through the heat treatment solid melting furnace body 101 by means of the ladder fixing block 52 provided.
