Description

Technical Field

[0001] This invention relates to the field of leather pressing machine maintenance tools, and particularly to a leather pressing machine maintenance tool. Background Technology

[0002] The rotary hearth furnace direct reduction technology involves feeding iron ore powder (or laterite nickel ore, vanadium-titanium magnetite, sulfuric acid slag, metallurgical dust, dust collector ash, steelmaking sludge, etc.) into carbon-containing pellets after batching, mixing, pelletizing, and drying. These pellets are then added to a rotary hearth furnace with an annular furnace and a rotating hearth. At a furnace temperature of approximately 1350℃, the iron ore is reduced by carbon as the furnace rotates once. When the iron content of the iron ore powder is above 67%, the direct reduction process using the rotary hearth furnace produces metallized pellets for use in power furnaces. When the iron content is below 62%, a molten iron reduction process using a rotary hearth furnace-smelting furnace is employed, producing molten iron for steelmaking. Typically, the metallization rate can reach over 80%, and the metallized pellets can be used as raw material for blast furnaces.

[0003] The rotary hearth furnace requires pressing rollers and pressing plates. The pressing machine for the rotary hearth furnace contains four pressing rollers and a total of 48 pressing plates. Due to the long-term operation of the equipment, the pressing plates of the pressing machine are often rusted. The existing removal method mostly uses electric hoists connected to lifting lugs, and then manually knocks off the rusted pressing plates. During the removal and hoisting, the large pulling force can easily cause the wire rope to break, leading to equipment or personal safety accidents. In addition, this removal method is extremely inefficient. Therefore, it is necessary to use safe auxiliary tools for the maintenance of the pressing machine. Summary of the Invention

[0004] The main objective of this invention is to provide a tool for repairing a leather pressing machine, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A tool for repairing a skin pressing machine includes a rotating column, two support seats, and several skin pressing pieces. The rotating column is rotatably mounted on the two support seats. Two pressing rollers are fixedly sleeved on the rotating column. Several skin pressing pieces are equidistantly attached to the outer surface of the two pressing rollers. A disassembly mechanism is placed on the top of the rotating column.

[0007] The disassembly mechanism includes a crossbar, auxiliary wheels, movable plates, threaded columns, and threaded sleeves. Bases are fixedly installed on the bottom surfaces of both ends of the crossbar, and jacks are fixedly installed on the bottom surfaces of both bases. Movable plates are movably sleeved inside the bases at both ends of the crossbar, and pins are fixedly installed at two points on the bottom surfaces of adjacent sides of the two movable plates.

[0008] Preferably, support blocks are fixedly installed at the bottom telescopic ends of both jacks, and both support blocks are placed on the top surface of the rotating column.

[0009] Preferably, each of the several pressure plates has two openings at both ends, and the two pins correspond to and are adapted to the openings.

[0010] Preferably, an extension plate is horizontally fixedly installed on one side surface of each of the two movable plates at the top of the crossbar, and a threaded sleeve is embedded in each of the two extension plates.

[0011] Preferably, each of the two threaded sleeves has a threaded post threaded through it, and a rotating handle is fixedly installed on the top of each of the two threaded posts.

[0012] Preferably, both movable plates are provided with through grooves, and a number of ball bearings are rolled and embedded in the top and side surfaces of the grooves.

[0013] Preferably, the bottom of the crossbar has two notches, the top surfaces of the two notches are fixedly connected to spring cylinders, and the bottoms of the two spring cylinders are fixedly installed with locking blocks.

[0014] Preferably, both of the card blocks have slots at their tops, and the bottom ends of both spring cylinders are fixedly connected to the bottom surface of the slots.

[0015] Preferably, auxiliary wheels are rotatably mounted at both ends of the two card blocks.

[0016] Preferably, the crossbar passes through the groove and overlaps with the ball bearing.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Adjust the rotating column so that the pressure plate to be disassembled is located at the top of the equipment. Then place the crossbar on the top surface of the pressure plate to be disassembled. The auxiliary wheel overlaps with the top surface of the pressure plate so that the crossbar can move left and right on the top of the pressure plate. Then push the movable plates on both sides closer to each other so that the pin is inserted into the corresponding opening. The spring cylinder can adjust the up and down movement of the movable plates on both sides within the range of motion to facilitate the insertion of the pin into the opening. After the pin is inserted into the opening, control the rotation adjustment of the corresponding rotating handle to fix the position of the extension plate and the movable plate. Finally, control the jacks on both sides to extend at the same time, thereby separating the pressure plate from the pressure roller.

[0019] 2. Due to limitations in the design or work site, this device can avoid accidents caused by sudden bouncing of the pressure plate during maintenance and dismantling operations, compared to traditional methods of dismantling by pulling, thus ensuring the safety of equipment and personnel.

[0020] 3. This device eliminates the need for auxiliary demolition tools such as pneumatic picks, impact drills, sledgehammers, and chisels. It is simple to operate, improves work efficiency, and generates virtually no noise. Compared with traditional demolition methods, it is more efficient. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figure 1-7 As shown, a tool for repairing a skin pressing machine includes a rotating column 2, two support seats 1 and several skin pressing pieces 3. The rotating column 2 is rotatably mounted on the two support seats 1. Two pressing rollers 4 are fixedly sleeved on the rotating column 2. Several skin pressing pieces 3 are equidistantly attached to the outer surface of the two pressing rollers 4. A disassembly mechanism 6 is placed on the top of the rotating column 2.

[0031] The disassembly mechanism 6 includes a crossbar 61, an auxiliary wheel 62, a movable plate 63, a threaded post 64, and a threaded sleeve 65. Both ends of the crossbar 61 are fixedly mounted with bases 69, and both bases 69 are fixedly mounted with jacks 610. Both ends of the crossbar 61 are movably connected to the movable plates 63 inside the bases 69. Two pins 68 are fixedly mounted at the bottom of the adjacent side surfaces of the two movable plates 63.

[0032] In this embodiment, support blocks 611 are fixedly installed at the bottom telescopic ends of both jacks 610, and both support blocks 611 are placed on the top surface of the rotating column 2.

[0033] In this embodiment, each of the several pressure plates 3 has two openings 5 ​​at both ends, and two pins 68 correspond to and fit the openings 5.

[0034] In this embodiment, an extension plate 67 is horizontally fixedly installed on one side surface of the two movable plates 63 adjacent to each other on the top of the crossbar 61, and a threaded sleeve 65 is embedded in each of the two extension plates 67.

[0035] In this embodiment, threaded posts 64 are threaded through both threaded sleeves 65, and rotating handles 66 are fixedly installed on the top of both threaded posts 64. By setting rotating handles 66, it is easy to drive the threaded posts 64 to fix the extension plate 67 so that it will not move and is easy to adjust.

[0036] In this embodiment, both movable plates 63 are provided with through grooves 615, and several balls 616 are rolled and embedded in the top and side surfaces of the grooves 615.

[0037] In this embodiment, the bottom of the crossbar 61 is provided with two notches, and the top surfaces of the two notches are fixedly connected with spring cylinders 614, and the bottoms of the two spring cylinders 614 are fixedly installed with locking blocks 612.

[0038] In this embodiment, the top of each of the two card blocks 612 is provided with a slot 613, and the bottom ends of the two spring cylinders 614 are fixedly connected to the bottom surface of the slot 613.

[0039] In this embodiment, auxiliary wheels 62 are rotatably mounted at both ends of the two locking blocks 612, and the auxiliary wheels 62 facilitate the movement of the crossbar 61.

[0040] In this embodiment, the crossbar 61 passes through the slide groove 615 and overlaps with the ball 616. By setting the crossbar 61 to pass through the slide groove 615 and overlap with the ball 616, it is convenient for the locking block 612 to move on the crossbar 61.

[0041] Working principle: In this invention, the jack 610 can also be replaced with a hydraulic rod and connected to an external hydraulic source. The external power source of the rotating column 2 can drive the rotating column 2 to rotate. By adjusting the rotating column 2 so that the pressure plate 3 to be disassembled is located at the top of the equipment, the crossbar 61 is placed on the top surface of the pressure plate 3 to be disassembled. The auxiliary wheel 62 overlaps with the top surface of the pressure plate 3 so that the crossbar 61 can move left and right on the top of the pressure plate 3. Then, the movable plates 63 on both sides are pushed closer to each other so that the pin 68 is inserted into the corresponding opening 5. The spring cylinder 614 is set so that the movable plates 63 on both sides can be adjusted within the range of vertical movement to facilitate the insertion of the pin 68 into the opening 5. After the pin 68 is inserted into the opening 5, the corresponding rotating handle 66 is controlled to rotate and adjust so that the position of the extension plate 67 and the movable plate 63 is fixed. Finally, the jacks 610 on both sides are controlled to extend simultaneously, so that the pressure plate 3 is separated from the pressure wheel 4. Repeating the above operation can completely disassemble all the pressure plates 3, which is convenient for maintenance, reduces the labor intensity of maintenance, improves maintenance efficiency, and ensures safe construction operations.

[0042] Due to limitations in design or work site conditions, this device avoids the risk of injury from sudden springing of the pressure plate during maintenance and dismantling operations, compared to traditional methods that rely on rigid pulling. This ensures the safety of equipment and personnel. Furthermore, this device eliminates the need for auxiliary tools such as pneumatic picks, impact drills, sledgehammers, and chisels during dismantling, simplifying operation, improving work efficiency, and generating virtually no noise. Compared to traditional dismantling methods, it offers significantly higher efficiency.

[0043] Traditional dismantling methods require multiple people to work together, involving steps such as vibration to loosen, hoisting and pulling, and dismantling one piece at a time. Traditional dismantling methods take more than 1.5 hours to dismantle one piece. The traditional rotary hearth furnace pressing machine has four pressing rollers and a total of 48 pressing templates, which takes about 5 days to dismantle, seriously affecting the maintenance speed. After using this device, dismantling one piece has been reduced from 1.5 hours to 20 minutes, reducing labor intensity and making the operation simple and labor-saving.

[0044] The circuits, electronic components, and control modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The scope of protection of this invention does not involve any improvement to the software and methods.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
