Description

Technical Field

[0001] The utility model relates to the technical field of flat glass manufacturing, and more specifically to a gate lifting device for a liquid flow channel of a flat glass melting furnace. Background Art

[0002] In the production process of flat glass, the liquid channel of the melting furnace is the key part connecting the melting area and the forming area, and is responsible for transporting the high-temperature molten glass to the forming area. The gate is an indispensable component of the process equipment of the flat glass production line. It is generally set above the liquid channel at the outlet of the melting furnace between the melting area and the forming area. By controlling the lifting and lowering of the gate, the glass liquid flow rate is adjusted, thereby controlling the width and thickness of the glass plate to meet the requirements of glass plates of different thickness and width of the flat glass production line.

[0003] At present, when controlling the flow rate of molten glass, it is necessary to install a lifting device at a specific position of the flow channel and use the lifting device to lift the gate. However, the existing gate lifting device has a complex structure and is expensive to manufacture and use.

[0004] After searching, the utility model patent with publication number CN203582677U discloses a gate lifting device for the liquid flow channel of a flat glass melting furnace. The advantages of this structure are simple structure and easy operation. While reducing the manufacturing and use costs, it achieves energy saving and consumption reduction and improves the accuracy of gate lifting and lowering adjustment.

[0005] However, in actual use, the structure uses a steel wire rope to adjust the lifting of the gate plate. During the lifting process, or when the gate plate needs to be lifted out of the liquid channel for wear maintenance, the gate plate is prone to shaking and the steel wire rope is prone to becoming tangled. In view of this, the utility model proposes a gate lifting device for the liquid channel of a flat glass melting furnace. Utility Model Content

[0006] In order to overcome the above defects of the prior art, the utility model provides a gate lifting device for a liquid flow channel of a flat glass melting furnace to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gate lifting device for a liquid flow channel of a flat glass melting furnace, comprising two support rods installed on the top of the liquid flow channel of the melting furnace, a gate movably installed in the liquid flow channel of the melting furnace, a support plate commonly provided at the top ends of the two support rods, a servo motor provided on the support plate, a support seat provided on one side of the servo motor, an axle rod rotatably provided inside the support seat, a winding disk provided outside the axle rod, and two groups of steel wire ropes wound around the outside of the winding disk.

[0008] It can be seen that the lifting device drives the winding drum to rotate through the servo motor to reel in and release the wire rope. The wire rope can drive the gate to perform lifting and lowering operations, thereby controlling the amount of flat glass flux flowing out of the liquid channel of the melting furnace.

[0009] In order to avoid the risk of the gate plate shaking due to the shaking of the wire rope and to avoid the wire rope from getting tangled, preferably, a restraining position clamping structure is provided at the bottom of the support plate between the two support rods, and the restraining position clamping structure includes a mounting plate, which is installed between the two support rods and located at the bottom of the support plate, and a rectangular opening is opened on the surface of the mounting plate, a screw is provided inside the rectangular opening, and a plurality of adjusting cylinders are provided outside the screw, locking nuts are provided on both sides of the adjusting cylinder, a constraint roller is provided on the surface of the adjusting cylinder, and an axle pin is provided between the adjusting cylinder and the constraint roller, the adjusting cylinder is slidably connected to the outside of the screw, and the locking nuts located on both sides of the adjusting cylinder are threadedly connected to the outside of the screw, and the constraint rollers are rotatably connected on the surface of the adjusting cylinder through axle pins, and every two constraint rollers are respectively located on both sides of the corresponding wire rope.

[0010] In order to realize the disassembly and assembly operation of the connecting ring, not only the turnover use of the connecting ring is realized, but also the gate plate can be conveniently removed for maintenance and replacement. Preferably, two connecting rods are arranged on the top of the gate plate, and the top ends of the two connecting rods are provided with connecting rings. Two threaded holes are provided on the surface of the gate plate, and the bottom ends of the two connecting rods are provided with threaded rods, which are threadedly connected to the threaded holes. A fixing plate is provided on the outside of the connecting rod, and a plurality of mounting holes are provided at the connection between the fixing plate and the gate plate, and bolts are threadedly installed inside the plurality of mounting holes.

[0011] In order to achieve the lifting effect of the gate plate, preferably, the output end of the servo motor is coaxially connected to the shaft rod, the winding drum is fixedly installed on the outside of the shaft rod, and one end of the wire rope passes through the support plate and is connected to the connecting ring.

[0012] Technical effects and advantages of the utility model:

[0013] By setting the restraining position clamping structure, the corresponding adjusting cylinder is slid outside the screw rod, and the distance between the two restraining rollers is adjusted, so that the two restraining rollers are located on both sides of the wire rope, which has a restraining effect on the wire rope, and the adjusted adjusting cylinder is positioned by rotating the locking nuts on both sides. At this time, when the wire rope is lifted and lowered between the two restraining rollers, the two restraining rollers restrain the wire rope to avoid shaking of the wire rope and confusion of the wire rope. In addition, the restraining roller can rotate on the surface of the adjusting cylinder through the shaft pin, which reduces the friction between the wire rope and the restraining roller during the winding process, and reduces the sense of frustration.

[0014] By connecting the connecting ring with the threaded rod at the bottom of the connecting rod and the threaded hole on the gate plate, the connecting ring has a certain disassembly and assembly effect to meet the effect of turnover use. After the threaded rod is connected to the gate plate, the connection between the fixed plate and the gate plate is achieved through bolts, thereby realizing double fixation of the connecting ring and avoiding the risk of the connecting ring falling off when the gate plate is raised or lowered. At the same time, by releasing the connection of the bolts and rotating the connecting ring, the threaded rod is turned out from the internal thread of the threaded hole, thereby realizing the removal of the connecting ring and the gate plate, which not only realizes the turnover use of the connecting ring, but also facilitates the removal and maintenance of the gate plate.

[0022] As attached Figure 1-5The gate lifting device of the liquid flow channel of a flat glass melting furnace shown in the figure includes two support rods 1 installed on the top of the liquid flow channel of the melting furnace, and a gate 2 movably installed in the liquid flow channel of the melting furnace. A support plate 3 is commonly provided at the top of the two support rods 1, a servo motor 4 is provided on the support plate 3, a support seat 5 is provided on one side of the servo motor 4, an axle rod 6 is rotatably provided inside the support seat 5, a winding drum 7 is provided outside the axle rod 6, and two groups of steel wire ropes 8 are wound around the outside of the winding drum 7.

[0023] In this structure, the interior of the melting furnace flow channel is used to flow the solution for manufacturing flat glass. The gate plate 2 is movably installed inside the melting furnace flow channel and is lifted and lowered by a lifting device to adjust the flow rate of the glass solution inside the melting furnace flow channel, thereby controlling the manufacturing thickness of the flat glass. When the gate plate 2 is upgraded and adjusted, it can be controlled by the servo motor 4. The servo motor 4 can drive the shaft 6 to rotate at the support seat 5, thereby rotating the external winding drum 7, winding and releasing the wire rope 8 outside the winding drum 7, and the wire rope 8 drives the gate plate 2 to be raised and lowered inside the melting furnace flow channel.

[0024] In a specific embodiment, as shown in the attached Figure 1 , 2 As shown in Figure 3, a restraining position clamping structure is provided between the two support rods 1 at the bottom of the support plate 3, and the restraining position clamping structure includes a mounting plate 9, which is installed between the two support rods 1 and located at the bottom of the support plate 3. A rectangular opening 10 is opened on the surface of the mounting plate 9, and a screw rod 11 is provided inside the rectangular opening 10. A plurality of adjusting cylinders 12 are provided outside the screw rod 11, and locking nuts 13 are provided on both sides of the adjusting cylinder 12. A constraint roller 14 is provided on the surface of the adjusting cylinder 12, and an axle pin 15 is provided between the adjusting cylinder 12 and the constraint roller 14. The adjusting cylinder 12 is slidably connected to the outside of the screw rod 11, and the locking nuts 13 located on both sides of the adjusting cylinder 12 are threadedly connected to the outside of the screw rod 11. The constraint roller 14 is rotatably connected on the surface of the adjusting cylinder 12 through the axle pin 15, and every two constraint rollers 14 are respectively located on both sides of the corresponding steel wire rope 8.

[0025] Specifically, in the process of raising and lowering the gate plate 2 by the wire rope 8, in order to prevent the wire rope 8 from shaking or becoming tangled, the operator adjusts the distance between the two constraint rollers 14 by sliding the corresponding adjustment cylinder 12 on the outside of the screw 11, so that the two constraint rollers 14 are on both sides of the wire rope 8, which has a constraint effect on the wire rope 8, and the adjusted adjustment cylinder 12 is positioned by rotating the locking nuts 13 on both sides. At this time, in the process of the wire rope 8 being raised and lowered between the two constraint rollers 14, the two constraint rollers 14 constrain the wire rope 8 to prevent the wire rope 8 from shaking and becoming tangled, and the constraint roller 14 can rotate on the surface of the adjustment cylinder 12 through the axle pin 15, thereby reducing the friction between the wire rope 8 and the constraint roller 14 during the winding process and reducing the sense of frustration.

[0026] In a specific embodiment, as shown in the attached Figure 1 , 4 As shown in Figure 5, two connecting rods 16 are provided on the top of the gate plate 2, and connecting rings 17 are provided on the top of the two connecting rods 16. Two threaded holes 18 are provided on the surface of the gate plate 2, and threaded rods 19 are provided on the bottom ends of the two connecting rods 16. The threaded rods 19 are threadedly connected to the threaded holes 18. A fixing plate 20 is provided on the outside of the connecting rod 16, and a plurality of mounting holes are provided at the connection between the fixing plate 20 and the gate plate 2, and bolts 21 are threadedly installed inside the plurality of mounting holes.

[0027] Specifically, in this structure, the connecting ring 17 can be connected to the threaded hole 18 on the gate plate 2 through the threaded rod 19 at the bottom of the connecting rod 16, so that the connecting ring 17 has a certain disassembly and assembly effect, which meets the effect of turnover use. After the threaded rod 19 is connected to the gate plate 2, the connection between the fixing plate 20 and the gate plate 2 is realized by the bolt 21, so as to realize the double fixation of the connecting ring 17, thereby avoiding the risk of the connecting ring 17 falling off when the gate plate 2 is raised or lowered.

[0028] When the connecting ring 17 needs to be replaced or the worn gate plate 2 needs to be maintained or replaced, the connection of the bolt 21 can be released, and the threaded rod 19 can be turned out from the internal thread of the threaded hole 18 by rotating the connecting ring 17, thereby realizing the removal of the connecting ring 17 and the gate plate 2. This not only realizes the turnover use of the connecting ring 17, but also facilitates the removal and maintenance of the gate plate 2.

[0029] In a specific embodiment, as shown in the attached Figure 1 As shown, the output end of the servo motor 4 is coaxially connected to the shaft 6 , the winding drum 7 is fixedly mounted on the outside of the shaft 6 , and one end of the steel wire rope 8 passes through the support plate 3 and is connected to the connecting ring 17 .

[0030] Specifically, the servo motor 4 can drive the shaft 6 to rotate, and drive the winding drum 7 to rotate, so that the wire rope 8 lifts and drops the connecting ring 17 to achieve the lifting and lowering operation of the gate plate 2.

[0031] Working principle of this utility model:

[0032] When the above structure is used, when the flux of the flat glass flows in the flow channel of the melting furnace, when the flow rate of the flux needs to be controlled, the lifting height of the gate plate 2 needs to be adjusted, specifically;

[0033] The servo motor 4 drives the shaft 6 to rotate at the support seat 5, thereby rotating the external winding drum 7, winding and releasing the steel wire rope 8 outside the winding drum 7, and the steel wire rope 8 drives the gate plate 2 to be raised and lowered inside the melting furnace flow channel, thereby controlling the amount of flux flowing in the melting furnace flow channel through the lifting height of the gate plate 2;

[0034] In the process of lifting and lowering the gate plate 2 by the wire rope 8, in order to prevent the wire rope 8 from shaking or becoming chaotic, the operator slides the corresponding adjustment cylinder 12 on the outside of the screw 11 to adjust the distance between the two constraint rollers 14, so that the two constraint rollers 14 are on both sides of the wire rope 8, which has a constraint effect on the wire rope 8, and the adjusted adjustment cylinder 12 is positioned by rotating the locking nuts 13 on both sides. At this time, in the process of the wire rope 8 being lifted and lowered between the two constraint rollers 14, the two constraint rollers 14 constrain the wire rope 8 to prevent the wire rope 8 from shaking and becoming chaotic, and the constraint roller 14 can be rotated on the surface of the adjustment cylinder 12 through the shaft pin 15, reducing the friction between the wire rope 8 and the constraint roller 14 during the winding process, thereby reducing the sense of frustration;

[0035] The connecting ring 17 can be connected to the threaded hole 18 on the gate plate 2 through the threaded rod 19 at the bottom of the connecting rod 16, so that the connecting ring 17 has a certain disassembly and assembly effect, which meets the effect of turnover use. After the threaded rod 19 is connected to the gate plate 2, the connection between the fixing plate 20 and the gate plate 2 is realized by the bolt 21, so as to realize the double fixation of the connecting ring 17, thereby avoiding the risk of the connecting ring 17 falling off when the gate plate 2 is raised or lowered.

[0036] At the same time, by releasing the connection of the bolt 21 and rotating the connecting ring 17, the threaded rod 19 is turned out from the internal thread of the threaded hole 18, thereby realizing the removal of the connecting ring 17 and the gate plate 2, which not only realizes the turnover use of the connecting ring 17, but also facilitates the removal and maintenance of the gate plate 2.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
