Description

Technical Field

[0001] The utility model belongs to the technical field of glass production equipment. Specifically, the utility model relates to a roll changing device for a glass annealing furnace. Background Art

[0002] Steel rollers are arranged in the glass annealing furnace. After long-term use, sulfides will adhere to the surface of the steel rollers. Therefore, the steel rollers need to be pulled out for cleaning.

[0003] In the prior art, the operation method of pulling out the steel roller is to extend a roller pulling trolley into the furnace and pull out the roller path. However, the roller path is too long. For the last part of the extraction, a forklift is needed to lift the roller path and use the lateral movement function of the forklift tines to pull it out, and the forklift needs to continuously make fine adjustments back and forth to prevent the steel roller from hitting the furnace wall. This method has cumbersome operations and high labor intensity, resulting in relatively low maintenance work efficiency. Moreover, due to the different levels of forklift drivers, it is inevitable to hit the furnace wall during repeated operations, posing a certain risk.

[0004] As disclosed in the Chinese patent document with the application number 202310471459.9, a roller wiping device for a transition roller of a slag box on a float glass production line is provided. During the serious pollution of the transition roller in the slag box and when the transition roller needs to be repaired or cleaned, the vehicle frame is pushed to extend the fixing rod and the mounting seat equipped with a temporary graphite block integrally under the transition roller. The height position of the support frame is adjusted through fasteners, and the force at both ends of the fixing rod is balanced through a counterweight assembly. The tensioning device is used to wind up the pull rope, and the pull rope pulls the connecting rod and drives the connecting rod to drive the graphite block to abut against the transition roller. Subsequently, the counterweight of the counterweight assembly is appropriately increased, and in cooperation with the tensioning device to further wind up the pull rope, the pressure between the graphite block and the transition roller is increased to improve the polishing effect of the graphite block, realizing precise fixed-point polishing and scrubbing of the transition roller. During this process, the transition roller remains rotating online, and it is not necessary to pull out the transition roller for cleaning. While ensuring the cleaning effect, the labor cost is reduced, and it has good economic benefits.

[0022] The following is a further detailed description of the specific implementation of the present utility model with reference to the accompanying drawings and through the description of embodiments, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solution of the present utility model and facilitate its implementation.

[0023] It should be noted that in the following embodiments, the "first" and "second" do not represent an absolute distinction relationship in terms of structure and / or function, nor do they represent the execution order, but are only for the convenience of description.

[0024] As Figure 1 and Figure 2 shown, the present utility model provides a roll-changing device for a glass annealing furnace, which includes a lifting platform 1 that can move vertically, a moving platform 2, an adjusting mechanism arranged on the lifting platform 1 and used to control the linear movement of the moving platform 2 in the horizontal direction, and a supporting mechanism arranged on the moving platform 2 and used to provide support for the steel roll.

[0025] Specifically, as Figure 1 and Figure 2 shown, the supporting mechanism includes a support frame 6 and a first sliding roll 8 and a second sliding roll 9 that are rotatably arranged on the support frame 6 and used to provide support for the steel roll. The first sliding roll 8 and the second sliding roll 9 are distributed in a V shape. The support frame 6 is of a U-shaped structure. The first sliding roll 8 and the second sliding roll 9 are located in the inner cavity of the support frame 6. The first sliding roll 8 and the second sliding roll 9 are inclined. One first sliding roll 8 and one second sliding roll 9 are provided. The first sliding roll 8 and the second sliding roll 9 are on the same straight line parallel to the first direction. There is an included angle between the rotation center lines of the first sliding roll 8 and the second sliding roll 9 and this included angle is less than 180 degrees. The outer circumferential surfaces of the first sliding roll 8 and the second sliding roll 9 are used to contact the outer circumferential surface of the steel roll, providing a supporting effect on the steel roll during the roll extraction process to ensure that the steel roll can be normally extracted in the horizontal direction.

[0026] As Figure 1 and Figure 2 shown, the support frame 6 is rotatably arranged. The lower end of the support frame 6 is installed on the moving platform 2 through a rotating shaft. The upper end of the support frame 6 is in an open state. The steel roll can pass through the upper opening of the support frame 6. The rotation center line of the support frame 6 is parallel to the first direction. The first direction is the horizontal direction and is parallel to the moving direction of the moving platform 2.

[0027] The supporting mechanism is arranged to be switchable between a supporting state and a laid-down state. The supporting mechanism in the supporting state can provide a supporting effect on the steel roll. As Figure 1As shown in the figure, the support mechanism further includes a support rod 7 for supporting the support frame 6 in a vertical state. The support rod 7 is rotatably connected to the support frame 6. When the support frame 6 is in a vertical state, the support mechanism is in a supporting state. The rotation center lines of the first roller 8 and the second roller 9 are in the same vertical plane, and the support rod 7 is in an inclined state. The upper end of the support rod 7 is rotatably connected to the support frame 6, and the lower end of the support rod 7 is embedded in the positioning groove provided on the top surface of the lifting platform 1. The support rod 7 provides a supporting effect on the support frame 6.

[0028] As Figure 1 shown in the figure, two support rods 7 are provided, and the two support rods 7 are on the same straight line parallel to the first direction.

[0029] When the support mechanism is in a folded state, the support rod 7 and the support frame 6 can be placed on the top surface of the lifting platform 1. The support frame 6 is not in a vertical state, and at this time, the support mechanism can reduce the occupied space.

[0030] As Figure 1 shown in the figure, the adjustment mechanism includes a handwheel 10 and a transmission mechanism 11 connected to the handwheel 10. The transmission mechanism 11 is connected to the moving platform 2. In this embodiment, the transmission mechanism 11 is a lead screw nut mechanism.

One end of the lead screw is fixedly connected to the handwheel 10, and the nut of the lead screw nut mechanism is fixedly connected to the bottom surface of the moving platform 2. The handwheel 10 is used for the operator to control the rotation. The handwheel 10 drives the lead screw to rotate, so that the moving platform 2 moves linearly along the first direction, realizing the transverse movement of the steel roller along the first direction, so as to ensure that the steel roller will not touch the kiln wall when being pulled out.

[0031] As Figure 1 shown in the figure, guide rails 12 are provided on the lifting platform 1, and a plurality of pulleys cooperating with the guide rails 12 are provided on the moving platform 2. Two guide rails 12 are provided, and the two guide rails 12 are on the same straight line parallel to the second direction. The second direction is a horizontal direction and is parallel to the first direction. The adjustment mechanism is located between the two guide rails 12. The length direction of the guide rails 12 is parallel to the first direction, and the guide rails 12 play a guiding role for the moving platform 2.

[0032] As Figure 1 shown in the figure, a base 3 is provided below the lifting platform 1, and a lifting actuator 13 connected to the lifting platform 1 is provided on the base 3. The lifting actuator 13 is used to control the lifting of the lifting platform 1, realizing the adjustment of the height of the support mechanism. The lifting actuator 13 is a telescopic member. In this embodiment, the lifting actuator 13 is a jack.

[0033] As Figure 1As shown, universal wheels 4 are provided on the base 3. There are four universal wheels 4 in total, and the four universal wheels 4 are distributed in a rectangle, which facilitates the overall movement of the device.

[0034] As Figure 1 shown, guide rods 5 are provided on the base 3. There are four guide rods 5 in total, and the four guide rods 5 are distributed in a rectangle. Guide holes for the guide rods 5 to pass through are provided on the lifting platform 1, and the guide rods 5 play a guiding role for the lifting platform 1.
