Description

Technical Field

[0001] The utility model relates to the technical field of glass melting furnace edge hanging beam equipment, and more specifically to a compact glass melting furnace edge hanging beam device. Background Art

[0002] See Figure 1 After the rolled glass is melted into a molten state in the glass melting furnace, it has a certain fluidity. The semi-fluid glass liquid flows into the calender from the edge 13 of the glass melting furnace. The upper pressure roller 11 and the lower pressure roller 12 of the calender press the glass into a glass strip of a certain thickness. After annealing and cutting, it is finally produced into a glass plate. In the entire production process, the glass in the rolling area is not formed and the area is open. The temperature control at this position directly affects the quality of glass forming. There is a transition area between the calender roller and the exit of the glass melting furnace, which is the edge area 13. The glass temperature in this area should generally be above 1100°C to ensure that the glass has a certain degree of workability. If the length of the edge area 13 is too small, the three necessary process structures of the flame-blocking brick 8, the gate plate 9 and the cover brick 10 cannot be installed. If the length of the edge area 13 is too long, the glass liquid will cool too quickly or unevenly, which will directly affect the subsequent forming process.

[0003] Taking the glass flow direction as the reference direction, from front to back, there are flame-blocking bricks 8, gate plates 9, and cover bricks 10. Their functions are:

[0004] Flame barrier brick 8: It is a closed wall at the kiln outlet to ensure the temperature and gas atmosphere inside the kiln. It is usually pulled out along the guide rail when the brick is damaged or the internal area needs maintenance;

[0005] Gate 9: cuts off the glass ribbon. When the glass production is abnormal, the gate is dropped to cut off the glass. It is usually made of metal material.

[0006] Cover brick 10: Placed above the edge to keep the temperature of the glass ribbon uniform in front of the roller. Similarly, it is usually pulled out along the guide rail when the brick is damaged or the internal area needs maintenance;

[0007] Since the maintenance area of ​​the flame-blocking bricks 8, gate plates 9 and cover bricks 10 is far away from the working position, the span is generally more than 10m to ensure that the staff are away from high temperature hazards during maintenance work. In order to ensure the strength and rigidity of the guide rails, the traditional hanging beam mechanism will choose profiles with larger grades. The profiles, that is, the walking trolleys hanging up and down the crossbeams of the large kiln, have their walking wheels placed on the outside. A certain gap is required between the walking trolleys to ensure that there is no abnormal movement after expansion and deformation. Therefore, the structural size of the entire system is too large, and the corresponding edge size is also correspondingly larger. This size should be as short as possible while ensuring the integrity of the above-mentioned mechanism to reduce heat loss and improve temperature uniformity. Utility Model Content

[0008] The technical problem to be solved by the present invention is how to shorten the length of the edge area.

[0009] The utility model solves the above-mentioned technical problems through the following technical means: a compact glass melting furnace edge hanging beam device, including a traveling car and a guide rail group, wherein the guide rail group is provided with a track adapted to the traveling car, the traveling car includes a trolley support column, traveling wheels, and a connecting shaft, one end of the traveling wheel is rotatably connected to both sides of the trolley support column through the connecting shaft, and the other end is connected to the hanging beam, and the traveling wheel is located in the track.

[0010] By arranging traveling wheels on both sides of the trolley support column and embedding them in the track of the guide rail group, the lateral occupied space is saved compared with the original U-shaped trolley support column, thereby reducing the occupied space of necessary process structures such as flame-blocking bricks, gate plates, and cover bricks, thereby shortening the length of the edge area.

[0011] As a preferred technical solution, the guide rail group includes a connecting bar, a pair of channel steels, and an I-beam. The pair of channel steels and the I-beam are fixedly connected by the connecting bar. The I-beam is located between the pair of channel steels. There are gaps between the channel steels and the I-beams, and between adjacent I-beams to form a plurality of tracks.

[0012] As a preferred technical solution, the connecting strip is located at one end of the channel steel and the I-beam away from the suspension beam.

[0013] As a preferred technical solution, a pair of the channel steels and the I-beams are connected and fastened by a plurality of connecting bars, and the plurality of connecting bars are linearly arranged along the length direction of the channel steels.

[0014] As a preferred technical solution, the gaps between the channel steel and the I-steel and between adjacent I-steels are adapted to the size of the trolley support column.

[0015] As a preferred technical solution, connecting columns are further provided between the channel steel and the I-steel and between adjacent I-steels.

[0016] As a preferred technical solution, the guide rail group is fixedly connected to the large kiln beam.

[0017] As a preferred technical solution, the large kiln cross beam is parallel to the connecting bar.

[0018] As a preferred technical solution, a connecting column is further provided between the pair of channel steels, and the connecting column passes through the I-beam.

[0019] As a preferred technical solution, one end of the connecting column is welded and fixed to a channel steel, and the other end is welded and fixed to another channel steel.

[0020] The beneficial effects of the present invention are:

[0021] (1) In the present invention, by arranging running wheels on both sides of the trolley support column and embedding them in the track of the guide rail group, the lateral occupied space is saved compared with the original U-shaped trolley support column, thereby reducing the occupied space of necessary process structures such as flame-blocking bricks, gate plates, and cover bricks, thereby shortening the length of the edge area, improving the thermal insulation capacity, and reducing the heat dissipation loss at the edge to achieve the purpose of environmental protection.

[0022] (2) In the present invention, a pair of channel steels and two I-beams are arranged between the channel steels, and the I-beams are fastened to the connecting strips, so that the entire guide rail group forms a module. During on-site installation, only one hoisting and welding is required, thus avoiding the problems of three traditional guide rail beams being welded separately on-site, resulting in poor straightness, inaccurate positioning, and a large workload.

[0023] (3) In the present invention, the guide rail assembly in this embodiment is an integral module with good rigidity. Compared with the traditional method, a smaller profile can be selected to further reduce the edge length. BRIEF DESCRIPTION OF THE DRAWINGS
