Abstract
The utility model discloses a support plate of a lower perimeter beam for a side wall steel structure of an annular furnace or a rotary hearth furnace. The support plate comprises a sector-shaped steel plate. Bolt oblate holes are arranged in the two radius edges of the sector-shaped steel plate. The support plate is characterized in that construction holes, which are circular, oblate or elliptical and provide convenience to workers for installation, are arranged in the middle parts of the sector-shaped steel plate. According to the utility model, the strength of the support plate is increased, the workload of design, manufacturing and machining is also reduced, the design and manufacturing cost is lowered, and the design and manufacturing speed is improved.
Description
Technical field
The utility model relates to a kind of annular furnace or rotary hearth furnace, relates in particular to a kind of annular furnace or rotary hearth furnace lower ring beam supporting plate structure.
Background technology
Annular furnace or rotary hearth furnace are current domestic widely used a kind of type of furnaces.On the side wall steel construction of this stove, have and support the lower ring beam that side wall is built by laying bricks or stones, lower ring beam is generally comprised of 2 channel-section steels, cover plate and gripper shoes, cover plate and channel-section steel and gripper shoe and channel-section steel are all bolted, form the overall structure of a box, whole lower ring beam is by side wall upright supports seat supports, as shown in Figure 1.For the ease of cover plate on lower ring beam and the connecting bolt between channel-section steel are installed, general design is all the gripper shoe below lower ring beam to be cut into the opening of zigzag fashion, as shown in Figure 2.This gripper shoe is because cutting area is larger, and its intensity is greatly affected, thereby has weakened the intensity of lower ring beam box-structure.In addition, the sawtooth opening size of cutting is less, is unfavorable for the connecting bolt of workman's construction and installation cover plate.
Utility model content
The purpose of this utility model has been to provide annular furnace that a kind of gripper shoe intensity is high or the side wall steel construction lower ring beam gripper shoe of rotary hearth furnace.
To achieve these goals, by the following technical solutions: the side wall steel construction lower ring beam gripper shoe of a kind of annular furnace or rotary hearth furnace, comprise fan-shaped steel plate, two radius edge places at fan-shaped steel plate two arcs have bolt flat round hole, it is characterized in that: in the middle of described fan-shaped steel plate, have circle, oblateness or the oval-shaped construction hole of being convenient to installation;
The radius in the construction hole of described circle is 20mm-150mm; Oblate construction pore radius is 20mm-150mm, and maximum length is 300mm; The minor axis maximum in oval-shaped construction hole is 150mm, and major axis maximum is 300mm.
Adopt structural design of the present utility model, construction working amount significantly to reduce, be conducive to accelerate design, manufacturing speed, reduce design, manufacturing cost, cut area is less simultaneously, and support strength is larger, is also more conducive to the installation of cover plate connecting bolt.
Accompanying drawing explanation
Fig. 1 is the structural representation of lower ring beam;
Fig. 2 is the structural representation of prior art;
Fig. 3 is the structural representation of the utility model embodiment 1;
Fig. 4 is the structural representation of the utility model embodiment 2;
Fig. 5 is the structural representation of the utility model embodiment 3.
In figure, 1-1 is side wall upright supports seat, and 1-2 is lower ring beam gripper shoe, and 1-3 is collar tie beam channel-section steel, and 1-4 is lower ring beam cover plate, and 1-5 is collar tie beam channel-section steel, and 1-6 is side wall column, and 2 is construction hole, and 3 is bolt aperture.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1: as shown in Figure 3, a side wall steel construction lower ring beam gripper shoe for annular furnace or rotary hearth furnace, comprises fan-shaped steel plate, and at fan-shaped steel plate, two radius edge places have bolt flat round hole 3, in the middle of fan-shaped steel plate, have circular construction hole 2, the radius in circular construction hole is 20mm-150mm.
Embodiment 2: as shown in Figure 4, as different from Example 1, in the middle of fan-shaped steel plate, be oblate construction hole, oblate construction pore radius is 20mm-150mm, and maximum length is 300mm;
Embodiment 3: as shown in Figure 5, as different from Example 1, also have oval-shaped construction hole on fan-shaped steel plate, the minor axis maximum in oval-shaped construction hole is 150mm, and major axis maximum is 300mm.
In gripper shoe, 1 construction hole is opened in general every 4 adjacent inner and outer ring bolt hole middles, and construction hole is according to interval layout design.If last only remaining 5-7 bolt hole, designs 2 adjacent construction holes or design 1 long flat round hole, make workman that the bolt being connected between cover plate and 2 channel-section steels can be installed easily.
