Description

Technical Field

[0001] The present invention relates to the technical field of glass substrate processing and manufacturing, and particularly relates to a disassembly and assembly tool for long rollers of a forming furnace. Background Art

[0002] At present, domestic liquid crystal glass substrates are mainly produced by the overflow down-drawing method. Long rollers play a very crucial role in the infiltration and emergency of the forming process. Due to the structural and technological characteristics of the glass forming furnace, after a long period of use or operation loss, the long rollers will not meet the process requirements to a certain extent. At this time, to ensure the quality of glass forming, the long rollers need to be replaced. Among them, the operation content of long roller replacement includes the withdrawal of the old long roller and the installation of the new long roller;

[0003] Currently, when withdrawing the old roller and installing the new roller, the commonly used method is that operators install auxiliary sleeves at both ends of the old and new rollers, and then drag the auxiliary sleeves to pull the old roller out of the glass forming furnace, or push the new roller into the glass forming furnace from the outside of the glass forming furnace;

[0004] During the installation and withdrawal of the old and new rollers, due to the deformation of the auxiliary tools caused by the high temperature in the furnace or the self-weight of the long rollers, and the lack of reference at any position during the operation of the personnel, the roller bodies of the old and new rollers are very likely to touch the glass in the furnace during the disassembly and assembly process, which may lead to glass short boards or even more serious blockage of materials in the furnace; at the same time, when the old roller is withdrawn, the asbestos coated on the surface of the long roller that has been used for a long time is very likely to break and separate from the shaft body due to sudden temperature change, which may pose a threat to the safety of the operators.

[0005] In summary, there is a need for a convenient, safe and reliable disassembly and assembly tool for long rollers at present. Summary of the Invention

The inlet roller support plates 73 and the inlet roller rubber plates 731 are arranged in correspondence;

[0044] When the new long roller 8 is placed and moved by the inlet roller solid sling 7, the inlet roller rubber plate 731 can contact the outside of the new long roller 8, improving the firmness of the connection between the inlet roller solid sling 7 and the new long roller 8, facilitating the inlet roller solid sling 7 to drive the new long roller 8 to move under the trolley bearing beam 3, and the arc-shaped inlet roller support plate 73 can make the placement of the new long roller 8 more stable;

[0045] A new long roller 8 and an old long roller 8a to be installed and withdrawn are provided outside and inside the glass forming furnace 9b. A short sleeve 9 is provided at one end of the new long roller 8 facing the rear gantry 1. A long sleeve 9a is provided at one end of the new long roller 8 facing the front-of-furnace gantry 2. The new long roller 8 and the old long roller 8a have the same composition structure. The connection methods of the long sleeve 9a, the short sleeve 9 and the old long roller 8a with the new long roller 8 are the same;

[0046] Both ends of the new long roller 8 are provided with assembly heads 81, and the outer sides of the assembly heads 81 are provided with threads. Both ends of the short sleeve 9 are provided with short pipe mounting sleeves 91, and the short pipe mounting sleeves 91 are threadedly connected to the assembly heads 81.

[0052] Embodiment 2

[0053] As Figures 1-14 shown, based on the above embodiment, the following content is further given in this embodiment:

[0054] To make it more comfortable for the incoming roller solid sling 7 to send the new long roller 8 into the glass forming furnace 9b, the following design is given in this embodiment:

[0055] One end of the incoming roller solid sling 7 facing the rear gantry 1 is provided with a first incoming roller auxiliary component 7a, and a second incoming roller auxiliary component 7b is arranged inside the incoming roller solid sling 7. The second incoming roller auxiliary casting includes an assembly plate 7b1, a vertical top plate 7b2 and a limit spring 7b3. The assembly plate 7b1 is arranged inside the sling main body 71, the assembly plate 7b1 is located in the interval of the incoming roller support plate 73, the middle of the bottom surface of the assembly plate 7b1 is provided with a vertical top plate 7b2, and both ends of the bottom surface of the assembly plate 7b1 are provided with limit springs 7b3. The vertical top plate 7b2 and the limit spring 7b3 both penetrate through the bottom end of the sling main body 71. An installation frame 712 connected to the limit spring 7b3 is arranged on the bottom surface of the sling main body 71. The bottom surface of the vertical top plate 7b2 is arc-shaped, the top surface of the assembly plate 7b1 is provided with an arc surface, the height of the top surface of the assembly plate 7b1 is lower than the height of the incoming roller support plate 73, and a plurality of auxiliary incoming roller wheels 7b11 are arranged on the arc surface of the assembly plate 7b1. The auxiliary incoming roller wheels 7b11 are rotatably connected to the assembly plate 7b1; the assembly plate 7b1 lower than the incoming roller support plate 7a1 can avoid affecting the tightness of the connection between the new long roller 8 and the incoming roller rubber plate 731 when the incoming roller solid sling 7 drives the new long roller 8 to move, and the connection between the limit spring 7b3 and the installation frame 712 can limit the pulling force required for the assembly plate 7b1 to lift and lower;

[0056] The first incoming roller auxiliary component 7a includes a drag plate 7a1, a connecting rod 7a2 and a pulling frame 7a3. The drag plate 7a1 is located inside the trolley bearing beam 3. An installation limit chute 31 is opened inside the trolley bearing beam 3. Connecting blocks 7a11 are arranged at both ends of the drag plate 7a1. The connecting blocks 7a11 are engaged and slidable with the installation limit chute 31. One side of the drag plate 7a1 is provided with a connecting rod 7a2. One end of the connecting rod 7a2 is rotatably connected to the drag plate 7a1. The other end of the connecting rod 7a2 is provided with a pulling frame 7a3. The pulling frame 7a3 is rotatably connected to the connecting rod 7a2. The pulling frame 7a3 is located on the bottom surface of the sling main body 71. A reinforcing plate 711 is arranged on the bottom surface of the sling main body 71. The reinforcing plate 711 is engaged and slidable with the pulling frame 7a3. A horizontal top plate 7a31 is arranged inside the pulling frame 7a3. The horizontal top plate 7a31 is arranged corresponding to the vertical top plate 7b2. The adjacent side of the horizontal top plate 7a31 and the vertical top plate 7b2 is arc-shaped. The horizontal top plate 7a31 is slidably connected to the sling main body 71; by providing the horizontal top plate 7a31, it is convenient to drive the vertical top plate 7b2 and the assembly plate 7b1 to rise together;

[0057] When the incoming roller entity sling 7 drives the new long roller 8 to move, the first incoming roller auxiliary assembly 7a will move along with the incoming roller entity sling 7. When the incoming roller entity sling 7 moves to a position close to the glass forming furnace 9b, the drag plate 7a1 moves to the end of the installation limit chute 31. At this time, when the incoming roller entity sling 7 moves, the drag plate 7a1 can drag the pulling frame 7a3 through the connecting rod 7a2, so that the horizontal top plate 7a31 jacks up the vertical top plate 7b2 and the assembly plate 7b1, and the auxiliary incoming roller 7b11 on the top surface of the assembly plate 7b1 can support the new long roller 8.

[0058] Through the lifting setting of the assembly plate 7b1 with the auxiliary incoming roller 7b11, when the incoming roller entity sling 7 drives the new long roller 8 to move, the incoming roller rubber plate 731 is connected to the new long roller 8. When the new long roller 8 needs to be separated and sent into the glass forming furnace 9b, the auxiliary incoming roller 7b11 is connected to the new long roller 8, so that the movement and installation of the new long roller 8 are more convenient.

[0059] Embodiment III

[0060] As Figures 1-2 and Figures 6-14 shown, on the basis of the above embodiments, the following content is further given in this embodiment:

[0061] To enable the incoming roller entity sling 7 to achieve the above functions, the outgoing roller entity sling 6a needs to solve the following problems: 1. It will not affect the operation of the incoming roller entity sling 7 when the incoming roller entity sling 7 is in use; 2. The incoming roller entity sling 7 needs to stably take out the old long roller 8a from the hearth of the glass forming furnace 9b. Therefore, the following technical solutions are given in this embodiment:

[0062] The outgoing roller entity sling 6a includes an outgoing roller assembly frame 6a1, an outgoing roller support plate 6a2 and a pressing plate 6a3. An installation ring 6a13 is provided on the top surface of the outgoing roller assembly frame 6a1, and the installation ring 6a13 is engaged and rotatable with the installation hook 63.

The anti - slip rubber strip 6a31 improves the stability of the connection between the roll - retreating entity sling 6a and the old long roll 8a during roll retreat. After the roll - retreating pressure plate 6a3 and the roll - retreating support plate 6a2 clamp the old long roll 8a, the roll - retreating entity sling 6a can drag the old long roll 8a to slide under the trolley bearing beam 3, making it more convenient for the old long roll 8a to retreat.

[0064] On one side of the third pulley facing the front - of - furnace gantry 2, a limit rope 64 is provided. One end of the limit rope 64 is provided with a limit hook 641. In the middle of one side of the roll - retreating assembly frame 6a1 facing the front - of - furnace gantry 2, a limit ring 6a14 is provided, and the limit ring 6a14 is engaged with the limit hook 641.

[0065] The roll - retreating entity sling 6a has two states: storage state and use state.

[0072] The operator provides a thrust through the long sleeve 9a to make the old long roll 8a start to withdraw from the furnace chamber. After the old long roll 8a withdraws to a certain extent, it is placed on the roll - retreating entity sling 6a.

[0073] The roll - retreating entity sling 6a can take the old long roll 8a out of the glass forming furnace 9b. When the old long roll 8a completely withdraws from the furnace chamber, the long sleeve 9a is separated from the old long roll 8a, and the roll - retreating is completed.

[0074] Specifically, one end of the old long roller 8a that exits is clamped and placed in the space between the roller withdrawal support plate 6a2 and the roller withdrawal pressure plate 6a3. An operator pushes the old long roller 8a by the long sleeve 9a, while on the other side, an operator pulls the short sleeve 9 and the roller withdrawal entity sling 6a by the short sleeve 9, so that the old long roller 8a moves together with the roller withdrawal entity sling 6a;

[0075] After the old long roller 8a completely exits the glass forming furnace 9b, the middle part of the old long roller 8a can be placed on the roller withdrawal support plate 6a2, and the long sleeve 9a is removed. The short sleeve 9 is placed on the roller feeding entity sling 7 for positioning. After the temperature of the old long roller 8a drops, the short sleeve 9 is removed and the old long roller 8a is taken off.

[0076] S2. Store the roller withdrawal entity sling 6a:

[0077] After the old long roller 8a exits, the roller withdrawal entity sling 6a rotates upward and changes from the use state to the storage state:

[0078] Specifically, the roller withdrawal assembly frame 6a1 rotates upward with the installation ring 6a13 as the point. The roller withdrawal assembly frame 6a1 approaches the bottom surface of the trolley bearing beam 3. The limit rope 64 is engaged with the limit ring 6a14 through the limit hook 641, so that the roller withdrawal assembly frame 6a1 is hung straight on the side of the third trolley 6;

[0079] S3. Feed in the new long roller 8:

[0080] The new long roller 8 is placed on the roller feeding entity sling 7, and the roller feeding entity sling 7 drives the new long roller 8 to move towards the glass forming furnace 9b;

[0081] The long sleeve 9a at one end of the new long roller 8 enters the glass forming furnace 9b for auxiliary positioning, and the short sleeve 9 at the other end provides thrust for the operator;

[0082] When the roller feeding entity sling 7 reaches the end, the first roller feeding auxiliary component 7a is forced to lift the second roller feeding auxiliary component 7b, and the new long roller 8 slides into the glass forming furnace 9b from the second roller feeding component;

[0083] The short sleeve 9 and the long sleeve 9a are removed, and the new long roller 8 falls into the glass forming furnace 9b to complete the roller replacement;

[0084] Specifically, in this step, the new long roller 8 contacts the roller supporting plate 73 of the incoming roller solid sling 7, and the incoming roller solid sling 7 drives the new long roller 8 to move towards the glass forming furnace 9b through the second pulley 5; when the incoming roller solid sling 7 drives the new long roller 8 to move to the tail of the pulley bearing beam 3, the drag plate 7a1 of the first incoming roller auxiliary assembly 7a engages with the installation limit chute 31. At this time, when the incoming roller solid sling 7 is pushed, the drag plate 7a1 will apply a reverse force to pull the connecting rod 7a2; the connecting rod 7a2 drives the horizontal top plate 7a31 to lift the vertical top plate 7b2, and the assembly plate 7b1 of the second incoming roller auxiliary assembly 7b can support the new long roller 8 through the auxiliary incoming roller 7b11, so that the new long roller 8 can smoothly slide into the glass forming furnace 9b along the auxiliary incoming roller 7b11.
