Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a corner tube type boiler support. Background Art

[0002] Corner tube boiler adopts self-supporting structure. The whole boiler is supported by downcomers and membrane walls, and is maintained and braced by rigid beams, which has good stability. Compared with traditional steel frame boilers, corner tube boilers have no steel frame structure, no separate frame support or suspension, which saves a lot of steel. The supporting structure of the main body of the corner tube boiler transfers the boiler load to the foundation through four supporting devices at the four corners. One of the four supporting devices is a fixed support point, usually welded, and the other three points are sliding points to accommodate the free expansion of the boiler.

[0003] The existing support structure of the corner tube boiler is a roller structure to achieve the purpose of expansion displacement, which has a complex structure, high cost, and is prone to deformation, which affects the smooth expansion.

[0004] The existing patent (Announcement No.: CN208688001U) discloses a boiler support structure for a layer-fired corner tube boiler, including an upper support, a lower support, a first base, a second base, a limit block, a bracket and other structures. For the sliding point of the corner tube boiler, the traditional rolling friction structure is changed to a sliding friction structure, which simplifies the structure and greatly reduces the cost while keeping the resistance almost unchanged.

[0005] In view of the above problems, the existing patent provides a solution, which is to support the boiler through a separate supporting structure. Although relative sliding displacement can be achieved when the supporting structure expands due to heat, since the downcomers of the corner tube boiler itself are arranged at the four corners of the boiler, they not only serve as water circulation channels, but also as a support frame for the boiler. If the corner tube boiler is supported by the existing patent, the installation positions of the four lower supports of the existing patent will inevitably conflict with the positions of the downcomers at the four corners of the boiler. In this way, it is necessary to modify the downcomer structure of the boiler itself, otherwise the boiler will not be able to realize the water circulation function, and the cost of such modification is relatively high. Summary of the invention

[0006] The utility model aims to provide a corner tube boiler support, which can solve the problem that the installation positions of four lower supports will inevitably conflict with the positions of downcomers at the four corners of the boiler.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 7 , the utility model provides a technical solution:

[0030] A corner tube boiler support comprises a base 1, wherein three slide grooves 2 11 are provided inside the base 1, and a slide seat 3 is slidably connected in the slide grooves 2 11, the cross section of the slide seat 3 is T-shaped, and a plurality of balls 2 31 are rotatably connected on the outer surface of the end of the slide seat 3 located in the slide grooves 2 11, a branch pipe 2 4 is fixedly connected to the slide seat 3 on the side facing away from the base 1, a branch pipe 1 2 is also fixedly connected to the side of the base 1 adjacent to the slide seat 3, and a transverse tube 5 is fixedly connected to the outer surfaces of the branch pipes 1 2 and the branch pipes 2 4, the transverse tube 5 is connected to the branch pipes 1 2 and 4, and a pipeline compensator 6 is fixedly connected between two adjacent transverse tubes 5.

[0031] By adopting the above technical scheme, two adjacent transverse tubes 5 are connected by the pipeline compensator 6. When the transverse tube 5 expands due to heat, the pipeline compensator 6 can compensate for the axial, lateral and angular thermal deformation of the transverse tube 5, and can also absorb vibration to reduce the impact of equipment vibration on the pipeline. At the same time, when the transverse tube 5 moves due to thermal expansion, the slide seat 3 can slide in the slide groove 2 11, so that the branch pipe 1 2 and the branch pipe 2 4 are driven to produce sliding displacement when the transverse tube 5 expands due to heat. Since multiple branch pipes 2 4 are interconnected and branch pipe 2 4 is connected to branch pipe 1 2, the support frame composed of branch pipe 1 2, branch pipe 2 4 and transverse tube 5 can not only play the function of supporting the boiler, but also water can flow in branch pipe 1 2 and branch pipe 2 4, so that branch pipe 1 2, branch pipe 2 4 and transverse tube 5 are used as water circulation channels.

[0032] Specifically, Figure 1 and Figure 4 As shown, a support mechanism 1 7 and a support mechanism 2 9 are fixedly connected on one side of the base 1 adjacent to the slide 3, and the support mechanism 7 includes a fixed seat 71 fixedly connected on one side of the base 1 adjacent to the slide 3, a slide groove 72 opened inside the fixed seat, a slider 73 slidably connected in the slide groove 72, and an arc-shaped guide frame 74 fixedly connected on one side of the slider 73, and the inner surface of the arc-shaped guide frame 74 is in contact with the outer surface of the cross tube 5.

[0033] By adopting the above technical solution, when the transverse tube 5 is displaced by thermal expansion, it can drive the arc guide frame 74 to move, so that the arc guide frame 74 drives the slider 73 to slide in the slide groove 72, and the arc guide frame 74 is used to support the transverse tube 5 that is displaced by thermal expansion.

[0034] Specifically, Figure 5 and Figure 6 As shown, the supporting mechanism 2 9 includes a fixing seat 2 91 fixedly connected on the side adjacent to the base 1 and the slide seat 3, a cover body 92 fixedly connected on the side of the fixing seat 2 91 away from the base 1, an active cavity 94 opened inside the fixing seat 2 91, an active groove 93 opened inside the cover body 92, a connecting column 96 inserted in the active groove 93, a disk body 95 fixedly connected on the end adjacent to the connecting column 96 and the fixing seat 2 91, an arc-shaped guide frame 2 97 fixedly connected on the end away from the connecting column 96 and the fixing seat 2 91, and a ball 1 rotatably connected to the disk body 95 and the side away from the connecting column 96.

[0035] By adopting the above technical solution, the disk 95 can move in the movable cavity 94 through the ball bearing 1. Different from the support mechanism 1 7, the arc guide frame 2 97 of the support mechanism 2 9 has no structure to guide it when moving. Therefore, the arc guide frame 2 97 can achieve multi-directional translation, but the role played by the arc guide frame 2 97 is the same as that played by the arc guide frame 1 74.

[0036] Specifically, Figure 1 and Figure 7 As shown, the base 1 is also connected to an auxiliary leveling mechanism 8 on the side adjacent to the slide 3, and the auxiliary leveling mechanism 8 includes two screws 82 rotatably connected to the side adjacent to the base 1 and the slide 3, two guide posts 81 fixedly connected to the side adjacent to the base 1 and the slide 3, two plates 83 screwed on the outer surfaces of the two screws 82, and two guide grooves 86 respectively opened in the two plates 83, and the two guide posts 81 are respectively inserted in the two guide grooves 86. A through groove 84 is opened inside one of the plates 83, and a laser emitter 85 is fixedly connected to the adjacent side of the other plate 83 and the plate 83 with the through groove 84 opened inside.

[0037] By adopting the above technical solution, rotating the screw rod 82 can drive the plate body 83 to rise and fall, and the plate body 83 can support the pipeline compensator 6. When the pipeline compensator 6 is connected to the cross pipe 5, by adjusting the height of the two plates 83, when the laser generated by the laser emitter 85 on one of the plates 83 can pass through the through groove 84, the heights of the two plates 83 are the same. At this time, the pipeline compensator 6 is placed on the plate body 83, and both ends of the pipeline compensator 6 are located on the same horizontal plane, so that the pipeline compensator 6 can be connected to the cross pipe 5 more quickly.

[0038] Specifically, Figure 1 and Figure 3 As shown, the ends of the branch pipe 1 2 and the branch pipe 2 4 away from the slide seat 3 are connected with a sealing gasket 10. The ends of the branch pipe 1 2 and the branch pipe 2 4 away from the slide seat 3 are provided with a sealing groove 12 for accommodating the sealing gasket 10, and the insides of the branch pipe 1 2, the branch pipe 2 4 and the sealing gasket 10 are provided with a through hole 13.

[0039] By adopting the above technical solution, the sealing gasket 10 can play a sealing role when the branch pipe 1 2 and the branch pipe 2 4 are connected to the boiler, and the through hole 13 is opened for inserting the connecting bolts.

[0040] Working principle: When in use, connect the ends of branch pipe 1 2 and branch pipe 2 4 away from the base 1 to the downcomers on the four corners of the boiler. Branch pipe 1 2, branch pipe 2 4 and cross pipe 5 form a supporting frame, which not only supports the boiler, but also allows water to flow in branch pipe 1 2 and branch pipe 2 4, so that branch pipe 1 2, branch pipe 2 4 and cross pipe 5 are used as water circulation channels. The two supporting mechanisms can support and follow the cross pipe 5 that is displaced by thermal expansion. Support mechanism 1 7 and support mechanism 2 9 both have a moving function. When the cross pipe 5 is displaced by thermal expansion, support mechanism 1 7 and support mechanism 2 9 can move synchronously with the cross pipe 5, thereby ensuring the stability of the overall structure.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
