Description

Technical Field

[0002] With the progress of society and the rapid growth of urban population, the practice of incinerating urban domestic waste and generating electricity has become popular in China; moreover, the tonnage and floor area of ​​waste incinerators and waste heat boilers are increasing. Usually, a canopy is set on the top of the waste heat boiler, which is supported by columns standing on the steel frame 2 on the top of the waste heat boiler. In order to meet the needs of debugging and maintenance, a special single-track beam is also required to be set on the top of the waste heat boiler as a supporting facility for a small electric hoist, which is used to lift valves or other small equipment (less than 3 tons); however, the single-track beam needs to be equipped with independent columns to transfer the load to the steel frame on the top of the waste heat boiler). This increases the equipment investment and construction work volume, and also prolongs the construction time. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is a further description with reference to the embodiments shown in the accompanying drawings.

[0021] The track beam structure of the canopy on the top of the waste heat boiler shown in the attached figure includes a number of canopy cross beams 5 arranged parallel to each other and installed on the steel frame 2 on the top of the waste heat boiler through a number of vertically arranged canopy columns 3, and a canopy color steel plate 1 laid on the canopy cross beams. The lower ends of the several canopy cross beams are jointly fixed with the track beam 6, and the track beams are arranged perpendicular to the canopy cross beams, so that the electric hoist 4 can be hung on the track beam and move along the track beam. In order to enhance the strength of the canopy structure, a number of reinforcements are arranged between the canopy cross beam and the track beam; the reinforcements include a trapezoidal track beam support plate 7 and / or a track beam support tube 8 and / or a canopy cross beam reinforcement rib 9.

[0022] The canopy cross beam is an H-shaped steel, and the track beam is an I-shaped steel.

[0023] The sides of two narrow upper and wide lower trapezoidal track beam support plates 7 are symmetrically fixed on the left and right webs of the canopy cross beam, and the bottom ends of the trapezoidal track beam support plates are fixed on the top of the track beam, thereby achieving the reinforcement support; this is the first arrangement structure (see Figure 3 , Figure 4 AA section shown).

[0024] A track beam support tube 8 is vertically fixed to the bottom end of the canopy cross beam and the top end of the track beam. At the same time, the top ends of two track beam support tubes arranged in an eight-shaped shape are fixed to the left and right sides of the web of the canopy cross beam and the bottom ends are fixed to the top end of the track beam; the bottom ends of the other two track beam support tubes arranged in an inverted eight-shaped shape are fixed to the top end of the track beam, and the top ends are respectively fixed to the bottom ends of the canopy cross beam, so as to achieve the reinforced support; obviously, the horizontal plane projection of the two track beam support tubes arranged in an eight-shaped shape and the track beam support tubes arranged in an inverted eight-shaped shape is a cross. This is the second arrangement structure (see Figure 3 , Figure 4 BB section shown).

[0025] A track beam support tube is vertically fixed to the bottom end of the canopy crossbeam and the top end of the track beam. Two canopy crossbeam reinforcement ribs 9 are arranged parallel to the web of the canopy crossbeam and inserted between the top plate edge and the bottom plate edge on the left and right sides of the canopy crossbeam and then fixed to the top plate and the bottom plate of the canopy crossbeam. At the same time, the top ends of the two track beam support tubes arranged in an eight-shaped shape are fixed to the left and right sides of the top of the one track beam support tube, while the bottom ends are fixed to the top of the track beam. The other two track beam support tubes arranged in an inverted eight-shaped shape have their top ends fixed to the bottom end of the canopy crossbeam, while the bottom ends are fixed to the front and rear sides of the bottom of the one track beam support tube, thereby achieving the reinforced support. Obviously, the horizontal plane projections of the two track beam support tubes arranged in an eight-shaped shape and the track beam support tubes arranged in an inverted eight-shaped shape are also cross-shaped. This is the third arrangement structure (see Figure 3 , Figure 4 CC section shown).

[0026] A track beam support tube is vertically fixed between the bottom end of the canopy crossbeam and the top end of the track beam. The top ends of the two track beam support tubes arranged in an "eight" shape are fixed to the left and right sides of the web of the canopy crossbeam, while the bottom ends are respectively fixed to the top end of the track beam. At the same time, the top ends of two trapezoidal track beam support plates that are wide at the top and narrow at the bottom are fixed to the bottom end of the canopy crossbeam, while the sides are respectively fixed to the front and rear sides of the track beam support tube, thereby achieving reinforced support. Obviously, the horizontal plane projection of the two track beam support tubes fixed in an "eight" shape and the two trapezoidal track beam support plates is still a cross shape; this is the fourth arrangement structure (see Figure 3 , Figure 4 DD section shown).

[0027] A track beam support tube is vertically fixed at the bottom end of the canopy crossbeam and the top end of the track beam, and two canopy crossbeam reinforcement ribs are arranged parallel to the web of the canopy crossbeam and are simultaneously inserted between the top plate edge and the bottom plate edge on the left and right sides of the canopy crossbeam and then fixed to the top plate and the bottom plate of the canopy crossbeam; and two trapezoidal track beam support plates that are narrow at the top and wide at the bottom are symmetrically fixed between the left and right sides of the one track beam support tube and the top end of the track beam; and two trapezoidal track beam support plates that are wide at the top and narrow at the bottom are symmetrically fixed between the front and rear sides of the one track beam support tube and the bottom end of the canopy crossbeam, so as to achieve reinforced support; obviously, the horizontal plane projections of the two trapezoidal track beam support plates that are narrow at the top and wide at the bottom and the two trapezoidal track beam support plates that are wide at the top and narrow at the bottom are still in the shape of a cross. This is the fifth arrangement structure (see Figure 3 , Figure 4 EE section shown).

[0028] Since a canopy is installed on top of the waste heat boiler, the installation position and structural form of the track beam can be considered at the early stage of canopy design. The track beam 6, trapezoidal track beam support plate 7 and track beam support tube 8 are directly installed under the canopy crossbeam 5, directly and effectively transferring the load to the canopy crossbeam 5 to the greatest extent. The inclined setting of the track beam support tube 8 can not only reduce the span between the straight support tubes but also better transfer the lateral force of the electric hoist 4 during movement. The canopy crossbeam reinforcement ribs 9 strengthen the local stress points in the canopy crossbeam 5. In addition, Figure 2 The lifting area shown in the figure is set outside the steel frame of the waste heat boiler, thereby expanding the lifting range and facilitating the handling of small equipment. The above simple and effective method can fully meet the requirements of lifting valves or other small equipment.
