Description

Technical Field

[0001] This utility model relates to the field of auxiliary installation technology for tempering furnace roller conveyors, and in particular to an installation device for tempering furnace roller conveyors. Background Technology

[0002] A tempering furnace is a specialized industrial equipment for producing tempered glass using physical or chemical methods. A glass tempering unit mainly consists of four parts: the glass feeding section, the convection heating section, the flat tempering section, and the glass unloading section, as well as a high-pressure centrifugal fan, air supply ducts, an air collection box, air circuits, an electrical control cabinet, and an operating platform. The front-end drive of the glass feeding section is a steel-coated roller conveyor. The glass sheet to be processed is placed on the roller conveyor and transported forward to a predetermined position in front of the furnace. A photoelectric switch located near the transition roller conveyor in front of the furnace activates, stopping the rollers and placing the glass in a ready-to-process state.

[0003] Roller conveyors are indispensable devices in the production and processing of large-gear tempered coated glass. The installation and working quality of the roller conveyors directly determine the safety of glass production and processing. Tempering furnaces have numerous roller conveyors that need to be precisely positioned within the furnace's cooling fan grid. The roller conveyors are generally long and slender. During installation, workers need to lift the rollers. Currently, a soft cloth is placed underneath the roller, one end is placed directly on the cooling fan grid, and the other end is pushed to move the roller along the grid until it reaches the other end. Two people then work together to place the two ends of the roller onto the cooling fan grid. However, this method is not only inefficient but also easily causes wear and tear on the surfaces of the rollers and cooling fan grid. Therefore, how to efficiently install the rollers through the cooling fan grid is a technical challenge, requiring the design of a specialized installation device for tempering furnace roller conveyors. Summary of the Invention

[0004] This utility model proposes a tempering furnace roller conveyor installation device to solve the installation problem of tempering furnace roller conveyor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tempering furnace roller conveyor installation device is used to install the roller conveyor of the tempering furnace above a corresponding cooling air grid. It includes a support base, small shafts, rollers, and E-type retaining rings. The main body of the support base is an arc-shaped seat with a plate-like structure. Two connecting plates extend from the arc ends of the support base, and the distance between the two connecting plates forms an opening at the top of the support base. Two rollers are located on the outer sides of both ends of the support base. Two small shafts are located corresponding to the rollers. The small shafts pass through the rollers along the axial direction of the rollers and install the two rollers on the two connecting plates respectively. Two E-type retaining rings are installed in the shaft grooves of the small shafts located on the outer sides of the rollers.

[0007] Two rollers are placed on the top of the bars on both sides of the cooling air grid. The first end of the roller is placed in the support seat. The support seat is subjected to force and elastically deforms. The distance between the two connecting plates is reduced to the limit of the E-type snap ring. The tail end of the roller is pushed and pulled. The roller and the steel furnace roller mounting device below it move synchronously along the extension direction of the cooling air grid through the rollers.

[0008] In one possible implementation, the length of the opening at the top of the support base, i.e., the distance between the two connecting plates, is greater than the diameter of the roller conveyor to be installed, which is inserted into the support base from the opening.

[0009] In one possible implementation, the support base is provided with a rope-tying hole, through which a long rope is tied to the support base.

[0010] In one possible implementation, the small shaft is a multi-step cylindrical structure, which sequentially includes a coaxial first limiting end, a first step, a second step, a shaft groove, and a third step. The first limiting end is located inside the support base, the support base is mounted on the first step, the roller is mounted on the second step, the shaft groove is formed outside the roller, and the third step is located outside the shaft groove.

[0011] In one possible implementation, the diameter of the first limiting end is larger than the diameter of the first step, and the connecting plate of the support base is provided with a connecting pin hole. The connecting pin hole is sleeved on the first step to realize the connection between the small shaft and the support base. The first limiting end is located inside the connecting plate, and the diameter of the first limiting end is larger than the diameter of the connecting pin hole.

[0012] In one possible implementation, the axial length of the first step is greater than the axial length of the connecting pin hole.

[0013] In one possible implementation, the diameter of the first step is larger than the diameter of the second step, the roller has a connecting shaft hole along its axis, the connecting shaft hole is fitted onto the second step to achieve the connection between the roller and the small shaft, and the diameter of the first step is larger than the diameter of the connecting shaft hole.

[0014] In one possible implementation, the axial length of the second step is equal to the axial length of the roller.

[0015] In one possible implementation, the diameter of the shaft groove is smaller than the diameters of the second step and the third step, forming a recessed groove, and the E-type snap ring is installed in the shaft groove and located outside the roller.

[0016] In one possible implementation, the roller is a V-shaped nylon grooved roller, that is, the roller has a groove around its periphery and the roller cross-section is V-shaped.

[0017] This utility model discloses a tempering furnace roller conveyor installation device, which is specially developed to assist in the installation of tempering furnace roller conveyors. In use, the first end of the roller conveyor is placed in the support base. The rollers on both sides of the support base are located at the top of the cooling air grid on both sides. The worker pushes the tail end of the roller conveyor, and the rollers are forced to move forward along the cooling air grid, thereby driving the roller conveyor forward until the first end of the roller conveyor moves to the other side of the cooling air grid of the tempering furnace. Then, the worker lifts it up and places the end of the roller conveyor in the set position for installation.

[0018] Compared with existing technologies, the advantages of this invention are as follows: Installed below the roller conveyor and placed on the cooling fan grille, it converts the hard friction between the roller conveyor and the cooling fan grille during movement into rolling friction, avoiding collisions between the roller conveyor and the cooling fan grille, protecting the surface quality of the roller conveyor, preventing damage during installation, saving labor for installation workers, and improving installation efficiency. Furthermore, the rollers of the installation device move along the cooling fan grille, effectively ensuring the roller conveyor moves straight forward and accurately positions the installation.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Please refer to the reference. Figures 1-4 A tempering furnace roller conveyor mounting device 100 is used to install the tempering furnace roller conveyor 200 above the corresponding cooling air grid 300. It includes a support base 1, small shafts 2, rollers 3, and E-type retaining rings 4. The main body of the support base 1 is an arc-shaped seat 11 with a plate-like structure. The two ends of the arc of the support base 1 extend to form two connecting plates 12. The distance between the two connecting plates 12 forms an opening 13 at the top of the support base 1. There are two rollers 3, which are located on the outer sides of the two ends of the support base 1. There are two small shafts 2, which correspond to the rollers 3. The small shafts 2 pass through the rollers 3 along the axial direction of the rollers 3 and install the two rollers 3 on the two connecting plates 12 respectively. There are two E-type retaining rings 4, which are installed in the shaft groove 24 of the small shaft 2 located on the outer side of the rollers 3.

[0028] See Figures 1-2 Two rollers 3 are placed on the top of the bars on both sides of the cooling air grid 300. The first end of the roller conveyor 200 is placed in the support seat 1. The support seat 1 is subjected to force and elastically deforms. The distance between the two connecting plates 12 is reduced to the limit of the E-type snap ring 4. The tail end of the roller conveyor 200 is pushed and pulled. The roller conveyor 200 and the steel furnace roller conveyor installation device 100 below it move synchronously along the extension direction of the cooling air grid 300 through the rollers 3.

[0029] Among them, the support seat 1 is used to support the roller 200 to be installed, the roller 3 is used to roll on the top of the cooling air grid 300 and drive the installation device and the roller 200 on it to move as a whole, the small shaft 2 is used to install the roller 3 on both sides of the support seat 1 to form the whole device, and the E-type retaining ring 4 is used to axially lock and limit the roller 3 and the small shaft 2.

[0030] The usage process of the tempering furnace roller conveyor installation device 100 of this utility model is as follows: Figure 1As shown, the extending direction of the cooling air grating 300 and the moving installation direction of the roller conveyor 200 are both parallel to the X direction. The installation device is placed on the corresponding cooling air grating 300, with two rollers 3 located on the top of the two side gratings of the cooling air grating 300. The rolling direction of the rollers 3 is the same as the extending direction of the cooling air grating 300. The first end of the roller conveyor 200 to be installed is placed into the support base 1 through the opening 13. The support base 1 is arc-shaped, partially enclosing the first end of the roller conveyor 200. The support base 1 is a sheet-like elastic material. When the weight of the roller conveyor 200 is applied, the support base 1 will undergo elastic deformation and retract along the shape of the roller conveyor 200, reducing the opening 13 at the top of the support base 1. After the first end of the roller conveyor 200 is placed in the support base 1, the elastic deformation of the support base 1 causes the posture of the small shaft 2 and the roller 3 to change until the E-type retaining spring 4 acts as an axial limit, and the small shaft 2 and the roller 3 no longer tilt or move. At this point, the roller conveyor 200 is assembled in the installation device. The worker is positioned on the side of the extended end of the roller conveyor 200 of the tempering furnace. Pushing the end of the roller conveyor 200 causes the mounting device below it to move forward. Specifically, the rollers 3 of the mounting device roll on the top of the bars of the cooling air grid 300, causing the entire mounting device, along with the roller conveyor 200 inside it, to move quickly along the cooling air grid 300 towards the other end of the tempering furnace. Once the roller conveyor reaches the other end, the worker lifts the end of the roller conveyor 200 and installs it on the tempering furnace. Then, the worker lifts the beginning of the roller conveyor 200, which has reached the designated installation position, and installs it on the tempering furnace, thus completing the assembly of the roller conveyor 200.

[0031] See Figures 3-4 The support base 1 of this utility model has an opening 13 on the top, which facilitates the quick placement of the roller 200 and avoids damage caused by the surface of the roller 200 rubbing against the connecting plate 12. When the roller 200 is placed in the support base 1, the elastic deformation of the support base 1 further surrounds the roller 200 and the opening 13 at the top becomes smaller, which can further fix the beginning of the roller 200, prevent the roller 200 from rolling left and right when pushed, and ensure that the roller 200 always moves accurately along a straight line.

[0032] This invention separates the roller conveyor 200 from the cooling fan grille 300, eliminating the need to place the roller conveyor 200 directly on the cooling fan grille 300 and push it to avoid hard friction damage to the surface quality of the roller conveyor 200. Instead, the support base 1 is used to fix and support the first end of the roller conveyor 200, and then the rollers 3 are used to move it. This not only effectively protects the surface of the roller conveyor 200, but also reduces friction, saves workers' physical strength, reduces installation difficulty, and improves the installation efficiency of the roller conveyor 200.

[0033] In some embodiments, the support base 1 may be made of a high-strength material such as elastic stainless steel, and may be integrally formed, or two connecting plates 12 may be welded to both ends of the arc-shaped support base 1 body.

[0034] In some embodiments, the length of the opening 13 at the top of the support base 1, i.e., the distance between the two connecting plates 12, is greater than the diameter of the roller conveyor 200 to be installed, and the roller conveyor 200 is inserted into the support base 1 through the opening 13. This structure facilitates the quick insertion of the first end of the roller conveyor 200 into the support base 1 without damaging the outer surface of the roller conveyor 200, which helps to improve installation efficiency.

[0035] In some embodiments, the support base 1 is provided with a rope-tying hole, through which a long rope is tied to the support base 1. After the worker pushes the roller conveyor 200 to its first end, together with the installation device, to the installation position at the other end of the tempering furnace and completes the installation, the worker can hold the rope and pull the installation device back along the cooling air grille 300 to the end of the tempering furnace, making it convenient for the worker to pick up and use. Preferably, the length of the long rope is greater than the length of the tempering furnace along the axis of the roller conveyor 200. Even if the installation device of this invention is located at the other end of the tempering furnace away from the worker, the long rope still has redundant length, and its free end hangs down from the end of the tempering furnace closer to the worker.

[0036] In some embodiments, see Figure 3 and Figure 4 The small shaft 2 is a multi-step cylindrical structure, comprising a coaxial first limiting end 21, a first step 22, a second step 23, a shaft groove 24, and a third step 25. The first limiting end 21 is located inside the support base 1, which is mounted on the first step 22. The roller 3 is mounted on the second step 23. The shaft groove 24 is located outside the roller 3, and the third step 25 is located outside the shaft groove 24. The small shaft 2 has multiple segments of different diameters, forming multiple steps. Each step is used to fix or limit different components, thereby limiting and fixing the support base 1, the roller 3, and the E-type retaining ring 4. In a more preferred embodiment, the small shaft 2 can be a one-piece structure cut from a single piece of steel.

[0037] In a further embodiment, see Figure 3 and Figure 4 The diameter of the first limiting end 21 is larger than the diameter of the first step 22. The connecting plate 12 of the support base 1 has a connecting pin hole 101, which is fitted onto the first step 22 to connect the small shaft 2 to the support base 1. The first limiting end 21 is located inside the connecting plate 12, and its diameter is larger than the diameter of the connecting pin hole 101. More preferably, the axial length of the first step 22 is greater than the axial length of the connecting pin hole 101. In this structure, the connecting plate 12 of the support base 1 is mounted on the first step 22 of the small shaft 2, and the first limiting end 21 inside the support plate acts as a limiting element, preventing the small shaft 2 from slipping out of the support plate.

[0038] In a further embodiment, see Figure 3 and Figure 4The diameter of the first step 22 is larger than the diameter of the second step 23. The roller 3 has a connecting shaft hole 301 along its axis, which is fitted onto the second step 23 to connect the roller 3 to the small shaft 2. More preferably, the axial length of the second step 23 is equal to the axial length of the roller 3. In this structure, the roller 3 is mounted on the second step 23 of the small shaft 2. One side of the roller 3 abuts against the outer side of the connecting plate 12 of the support base 1, and the other side of the roller 3 abuts against the inner side of the E-type retaining spring 4, effectively limiting the movement of the roller 3.

[0039] In a further embodiment, see Figure 3 and Figure 4 The diameter of the shaft groove 24 is smaller than the diameter of the second step 23 and the third step 25, forming a concave groove. The E-type retaining ring 4 is installed in the shaft groove 24 and located on the outside of the roller 3, realizing the installation and limiting of the E-type retaining groove. At the same time, the E-type retaining groove is located on the outside of the roller 3, effectively playing the role of axial limiting of the roller 3.

[0040] In some embodiments, the roller 3 is a V-shaped nylon grooved roller, that is, the roller 3 has a groove around its periphery and the cross-section of the roller 3 is V-shaped. In actual use, the grooved part of the V-shaped nylon grooved roller is engaged with the protruding position on the top of the cooling air grid 300, which plays a guiding role and prevents the roller conveyor 200 from moving in a skewed direction, so that the roller conveyor 200 can be accurately positioned and installed.

[0041] The installation device of this utility model has low cost and compact structure, and can be directly used in actual production work without any equipment modification, making it easy to promote.

[0042] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
