Description

Technical Field

[0001] This utility model belongs to the field of boiler support technology, specifically relating to a quick-installation gas-fired corner tube boiler base, suitable for gas-fired corner tube boilers. Background Technology

[0002] Gas-fired corner tube boilers are all installed on-site, making manufacturing significantly more difficult and time-consuming than factory production. To meet market demands, these boilers require rapid assembly and shipment, necessitating that the base be shipped simultaneously with the boiler. This base must support the weight of the boiler and the steel frame while also meeting transportation requirements. Furthermore, the traditional connection between the base and the gas-fired corner tube boiler is a fixed weld. The thermal expansion generated during boiler operation can easily cause stress concentration at the joints, leading to weld cracking. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a quick-installation gas-fired angle tube boiler base, which features a compact structure and is convenient for hoisting and quick installation.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A quick-installation gas-fired corner tube boiler base includes a roller mechanism, a frame, and limiting baffles. The frame includes three longitudinal beams and multiple transverse beams connected together. The three longitudinal beams are equipped with a fixing platform for supporting the boiler column and multiple roller mechanisms. The fixing platform and multiple roller mechanisms are arranged in three rows and four columns. The fixing platform is located at the front end of the middle longitudinal beam. Two limiting baffles are arranged around the fixing platform and each roller mechanism. Each limiting baffle has a first surface for vertically positioning the boiler column, a second surface for limiting the boiler column in the horizontal and vertical directions, and a third surface for connecting the longitudinal beam. The second surface of the limiting baffles around the fixing platform is attached to the boiler column.

[0006] The advantages of this utility model compared to the prior art are:

[0007] This utility model designs a fixed platform as a fixing point for the boiler body. The roller mechanism design, with the fixed point and roller mechanism working together, allows the boiler body to expand backward and to the left and right from the fixed point, eliminating the problem of stress concentration at the joints caused by thermal expansion and leading to weld cracking. The limiting baffle has a dual function of limiting and connecting the boiler column and frame. The design of the second side realizes the limiting fixation to prevent slippage during transportation. The design of the first side allows it to hook the boiler column during hoisting to prevent the base from separating from the boiler body. The third side of the limiting baffle connects the base and the boiler body. The frame design of the horizontal and vertical beams realizes the integrated operation of rapid assembly and transportation. Attached Figure Description

[0023] The following is a detailed description with reference to embodiments. Unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art.

[0024] Example 1, Reference Figures 1-3This embodiment provides a quick-installation gas-fired corner tube boiler base, comprising a roller mechanism 1, a frame 2, and limiting baffles 3. The frame 2 includes three longitudinal beams 21 connected together and multiple transverse beams 22. The three longitudinal beams 21 are equipped with fixing platforms 4 for supporting the boiler column feet and multiple roller mechanisms 1, arranged in a three-row, four-column array. The fixing platform 4 is located at the front end of the middle longitudinal beam 21. Two limiting baffles 3 are arranged around the fixing platform 4 and each roller mechanism 1. The fixing platform 4 is further equipped with limiting baffles 3 on both sides along the transverse direction. Two limiting baffles 3 are provided. Two limiting baffles 3 are arranged on both sides of the fixed platform 4 along the longitudinal direction. Two limiting baffles 3 are arranged on both sides of the roller mechanism 1 along the transverse direction. Two limiting baffles 3 are arranged on both sides of the roller mechanism 1 along the longitudinal direction. Each limiting baffle 3 has a first surface 31 for vertically positioning the boiler column foot 5, a second surface 32 for limiting the transverse and longitudinal direction of the boiler column foot 5, and a third surface 33 for connecting the longitudinal beam 21. The second surfaces of the limiting baffles 3 located around the fixed platform 4 are all attached to the assembled boiler column foot 5.

[0025] Reference Figure 1 , Figure 2 and Figure 7 Both longitudinal beam 21 and transverse beam 22 are steel beams. The axial direction of the boiler body 6 is parallel to the length direction of the longitudinal beam 21. The expansion direction of the boiler body 6 is mainly manifested as axial expansion backward and transverse expansion along the middle longitudinal beam 21. The expansion direction is as follows: Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown by the solid arrow. Along the longitudinal direction, the column where the fixed platform 4 is located is the first column. The first column is equipped with front and rear limiting baffles 3 of the roller mechanism 1. The second surface 32 of the baffles 3 is attached to the installed boiler column base 5 for limiting and fixing, preventing it from sliding back and forth during transportation. The second, third and fourth columns are equipped with front limiting baffles 3 of the roller mechanism. The second surface 32 of the roller mechanism is attached to the boiler column base 5. The second surface 32 of the rear limiting baffle 3 of the second column is reserved with the boiler column base 5 with a 10mm gap for expansion space. The second surface 32 of the rear limiting baffle 3 of the third column is reserved with a 20mm gap for expansion space. The second surface 32 of the rear limiting baffle 3 of the fourth column is reserved with a 30mm gap for expansion space.

[0026] Reference Figure 3 , Figures 4-6Along the transverse direction, the second surface 32 of the inner limiting baffle 3 in the outer two rows abuts against the boiler column base 5, with a 10mm gap reserved between the second surface 32 of the outer limiting baffle 3 and the boiler column base 5 to allow for expansion space. The second surface 32 of the limiting baffle 3 on both sides of the middle row abuts against the boiler column base 5. The limiting baffle 3 on the middle longitudinal beam 21 is tightly abutted on both sides for limiting and fixing, preventing lateral sliding during transportation. While limiting, the limiting baffle 3 also hooks onto the boiler column base 5 during hoisting, serving as a connection. During assembly, the boiler column base 5 is pre-placed on the fixed platform 4 and roller mechanism 1. After the boiler body 6 is positioned, the second surface 32 of the limiting baffle 3 is prepared with reserved space, the first surface 31 positions the boiler column base 5, and the third surface 33 is welded to the longitudinal beam 21 to complete the fixing. After the base is transported to the site, there is no need to disassemble the boiler column base 5 and the limiting baffle 3.

[0027] Example 2, Reference Figure 4 and Figure 6 The limiting baffle 3 comprises a horizontally arranged first plate 34 and a vertically arranged second plate 35. The first plate 34 and the second plate 35 are connected as a single unit, forming a right-angled surface with the right-angled opening facing inward. The horizontal surface of the right-angled surface serves as the first surface 31, the vertical surface as the second surface 32, and the bottom surface of the second plate 35 as the third surface 33. This approximately inverted L-shaped limiting baffle 3 serves to position the boiler column base 5, constrain the roller mechanism 1, and connect the longitudinal beam 21. Example 3, Reference Figure 1 and Figure 2 The longitudinal beam 21 includes channel steel 210, upper steel plate 211, lower steel plate 212, and stiffening plate 213. There are two symmetrical channel steels 210, with their openings facing each other and arranged vertically. A pair of channel steels 210 connecting the upper steel plate 211 and the lower steel plate 212 are provided between them. Stiffening plate 213 is installed between the outer surface of the channel steel 210 and the lower surface of the upper steel plate 211. A support platform is formed at the boiler column base 5 using steel plates and stiffening plates. The roller mechanism 1 and the limiting baffle 3 are welded to the support platform.

[0028] Optionally, refer to Figure 8 and Figure 9Each roller mechanism 1 includes a roller groove 10, an upper pad 11, a lower pad 12, and a roller 13. The roller groove 10 is installed on the longitudinal beam 21, and the lower pad 12 is placed in the roller groove 10. The roller 13 is arranged between the upper pad 11 and the lower pad 12. The roller 13 is limited by the roller groove 10. The upper pad 11 is provided with clamping plates 14 on both sides to connect with the boiler column foot 5. The upper pad 11 is clamped on both sides by the clamping plates 14 without welding. The upper pad 11 and the clamping plates 14 are in sliding contact. The sliding direction is parallel to the axis of the roller 13. The axis of the roller 13 is perpendicular to the axis of the boiler body 6. The rolling friction coefficient is about 0.05, which is much smaller than the sliding friction coefficient of about 0.3. This greatly reduces resistance, eliminates stress concentration at nodes caused by thermal expansion, and avoids faults such as weld cracking and base deformation. The roller 13, upper pad 11 and lower pad 12 are made of 65Mn. The pads have high elasticity and fatigue resistance and can maintain elastic deformation under repeated alternating loads, making them less prone to permanent deformation or fatigue fracture.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions created by the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions created by the present invention without departing from the essence and scope of the technical solutions created by the present invention.
