Description

Technical Field

[0001] The invention belongs to the field of roller bottom heating furnace tooling and auxiliary tools, and in particular relates to a folding frame specially used for disassembling and assembling furnace rollers. Background Art

[0002] At present, many rollers of roller-bottom heating furnaces are made of ceramic rollers with steel structures embedded at both ends. Due to uneven force during use, ceramic rollers often break, which requires replacement of ceramic rollers. In addition, the surface of ceramic rollers is easy to adhere to molten impurities at high temperatures, forming irregular attachments of different sizes on the surface, which requires frequent disassembly, cleaning or replacement of ceramic rollers. At present, the replacement of furnace rollers is mostly done manually, which requires two people to coordinate the work. This method is highly dangerous, with a large workload, high intensity and low efficiency. There are also some disassembly and assembly fixtures that require the help of overhead cranes, which are difficult to operate alone and take up a lot of space. Summary of the invention

DETAILED DESCRIPTION

[0014] For better understanding and implementation, the present invention is further described below in conjunction with the accompanying drawings:

[0015] A folding frame specially used for disassembling and assembling furnace rollers, comprising a guide rail pair 14, wherein the guide rail pair 14 is provided with a rotating pin 15, and the rotating pin 15 is rotatably sleeved with one end of a cross beam 7; a support rod 2 is provided at the other end of the cross beam 7, a support rod groove 9 for accommodating the support rod 2 is provided at the upper part, a push-pull rod hole 8 for accommodating the push-pull rod 4 is provided at the middle part, a push-pull screw system 13 is provided on the side, and three hanging blocks 10 for hanging a push-pull plate 6 and two hanging brackets 12 for supporting the rotation of a support plate 5 are provided at the bottom.

[0016] Furthermore, a support wheel 1 is arranged at the lower part of the support rod 2; a stop pin 11 for hanging the push-pull plate 6 is arranged on the hanging block 10; a support plate 5 is arranged on the hanging bracket 12, and the support plate 5 is stopped when working with the hanging bracket 12 through the stop pin 11, and a support wheel 3 is arranged on the support plate 5; a push-pull plate 6 is arranged on the push-pull screw system 13, and the push-pull plate 6 is stopped when working with the push-pull screw system 13 through the stop pin 11, and a push-pull rod 4 with an adjustable position is arranged on the push-pull plate 6.

[0017] Furthermore, hanging holes 18 are provided on the support plate 5 and the push-pull plate 6 .

[0018] Furthermore, the folding frame can be placed on any side of the furnace body 16 , or placed on both sides of the furnace body 16 for use in pairs.

[0019] When the crossbeam 7 of the present invention is not in operation, it can be folded and leaned against a certain position of the furnace body 16 .

[0020] 1. When the furnace roller 17 needs to be disassembled:

[0021] First, the crossbeam 7 should be pushed along the guide rail pair 14 to move to the desired replacement position.

[0022] Then unfold the cross beam 7 to be roughly coaxial with the furnace roller 17, lower the support rod 2 and let the support wheel 1 support the ground.

[0023] Then pull out the anti-rotation pin 11 on the corresponding hanging block 10, unfold the support plate 5 and the push-pull plate 6 in turn, and then insert the anti-rotation pin 11 into the corresponding pin holes of the hanging bracket 12 and the push-pull screw system 13 to prevent the components from rotating during operation.

[0024] The push-pull rod 4 is pulled out from the push-pull rod hole 8 in the crossbeam 7, and is inserted into the hole of the furnace roller 17 to be replaced, and then connected with the push-pull plate 6.

[0025] The push-pull screw system 13 is started, and the push-pull plate 6 drives the push-pull rod 4 to drag the furnace roller 17 out of the furnace body 16, and the furnace roller 17 is dragged and placed on the supporting wheel 3.

[0026] The push-pull rod 4 and the push-pull plate 6 are loosened, the pulled furnace roller 17 is moved away from the supporting wheel 3 and placed in the storage area, and the push-pull rod 4 is pulled away from the furnace roller 17 .

[0027] 2. When the furnace roller 17 needs to be installed:

[0028] First, insert the push-pull rod 4 into the new furnace roller 17, place the furnace roller 17 on the supporting wheel 3, and then connect the push-pull rod 4 and the push-pull plate 6.

[0029] Secondly, the push-pull screw system 13 is started in reverse, and the push-pull plate 6 drives the push-pull rod 4 to drag the new furnace roller 17 into the furnace body 16.

[0030] After the new furnace roller 17 is in place, the push-pull rod 4 and the push-pull plate 6 are loosened and pulled out from the furnace roller 17. If there are furnace rollers 17 in other places that need to be installed, repeat the above action process.

[0031] 3. When all the furnace rollers 17 to be replaced are disassembled and assembled, the entire structure can be folded and stored:

[0032] First, place the push-pull rod 4 in the push-pull rod hole 8 on the crossbeam 7 .

[0033] Then unplug the anti-rotation pins 11 on the hanger 12 and the push-pull screw system 13 respectively, turn the support plate 5 and the push-pull plate 6 over and place them on the corresponding hanger blocks 10 respectively, and insert and fix them with the anti-rotation pins 11 just removed.

[0034] Then the support rod 2 is turned over into the support rod groove 9 on the crossbeam 7 .

[0035] The cross beam 7 is rotated to be parallel to the side wall of the furnace body 16 and pushed to a certain position that does not affect normal operation; the entire structure is folded and placed.
