Description

Technical Field

[0001] The utility model relates to the technical field of boiler steel frame overlap, in particular to a boiler steel frame overlap structure. Background Art

[0002] During the installation of the boiler, a lap joint structure is required; after searching, the application number CN202322197200.8 was found, which discloses a boiler steel frame lap joint structure. When the position of the boiler is offset, there is no need to continue to adjust the position of the boiler. By starting the motor one, the motor one drives the rotating rod one to rotate, and the rotating rod one drives the moving plate to approach the boiler. The arc-shaped clamping plate that first touches the boiler drives the sliding plate at the bottom of the boiler to move, so that the arc-shaped clamping plates on both sides of the boiler finally clamp the boiler. When the height of the boiler needs to be adjusted, by starting the motor two, the motor two drives the connecting rod to rotate, and the connecting rod drives the rotating rod two to rotate synchronously, so that the fixed slider slides in the groove cavity of the spiral groove two, and drives the lifting rod to rise and fall, thereby adjusting the height of the boiler, which is convenient for the docking and installation of the pipeline.

[0003] The above structure can only support the longitudinally arranged boiler structure, and the application number is CN202220791905.5. In view of the problem that the connection method of the existing boiler steel frame structure is mostly weld connection, which is not convenient for overlapping or disassembly, and the boiler steel frame is heavy and occupies a large space, which makes it inconvenient to transport, the following solution is proposed, which includes a base, and two symmetrical mounting blocks are fixedly installed on the top of the base, and the tops of the two mounting blocks are each provided with a first slide groove, and columns are slidably installed in the two first slide grooves, and the tops of the two columns are each provided with a second slide groove, and vertical rods are slidably installed in the two second slide grooves. The tops of the two vertical rods are fixedly installed with an arc support frame, and one side of the two columns is provided with a third slide groove. The utility model can make the boiler steel frame easy to overlap or disassemble during use, so that it can be convenient for transportation, with a simple structure and easy use.

[0004] During actual use, it was found that the above structure requires simultaneous adjustment of the two corresponding sets of rotating rods during adjustment, which requires a high level of operation from the staff. Moreover, if a single set of structural support is used, the boiler is prone to tilting, which is inconvenient to use. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4, a boiler steel frame lap structure, including a base 1, a support assembly and a height adjustment assembly, the base 1 is provided with two groups of symmetrically arranged support assemblies, the support assembly includes a bracket 2 in the shape of an upper opening, a slide 3, a screw 4, a first worm gear 5, a first worm 6 and an arc block 7, the bracket 2 is provided with a slide groove near the center of the base 1, the slide 3 is slidably connected to the slide groove, an arc block 7 is provided above the slide 3, the bottom wall of the slide groove is provided with an active cavity, the bottom wall of the active cavity is rotatably provided with the first worm gear 5, the screw 4 is provided at the center above the first bolt, and a screw groove adapted to the screw 4 is provided below the slide 3. A first worm 6 is also provided which is meshed with the two groups of the first worm gears 5. The side walls of the two groups of the brackets 2 are also provided with a height adjustment assembly which drives the first worm 6 to rotate. The height adjustment assembly includes a cover body 8, a motor 9, a second worm gear 10 and a second worm 11. The cover body 8 is also provided on one side of the two groups of the brackets 2. The cover body 8 is provided on the base 1. The second worm 11 and two groups of second worm gears 10 are provided in the cover body 8. The two groups of the first worm 6 pass through the bracket 2 and are connected to the center of the second worm gear 10. The second worm 11 is meshed with the two groups of the second worm gears 10. The output end of the motor 9 passes through the cover body 8 and is connected to the second worm 11.

[0026] First, place the base 1 in the predetermined installation position, and use the legs 13 at the four corners of the base 1 to provide a stable bottom support for the entire lap joint structure, ensuring that it can be placed stably on the ground. The legs 13 will bear the weight of the boiler and the entire lap joint structure, and evenly transfer it to the ground to prevent shaking or tilting. When the boiler is to be placed, the slide 3 is located in the slide groove of the bracket 2, and the slide 3 and the slide groove are both T-shaped, ensuring the stability of the slide 3 sliding in the slide groove. The arc block 7 above the slide 3 waits to contact the bottom of the boiler in the initial state. The buffer pad 14 set above the arc block 7 can play a buffering role during subsequent contact and can better adapt to possible unevenness of the bottom of the boiler;

[0027] When the height of the boiler needs to be adjusted to accommodate requirements such as pipe docking and installation, the motor 9 in the height adjustment assembly is started. The output end of the motor 9 passes through the housing 8 and is connected to the second worm 11. The rotation of the motor 9 drives the second worm 11 to rotate. The second worm 11 disposed in the housing 8 meshes with the two sets of second worm gears 10. As the second worm 11 rotates, power is transmitted to the two sets of second worm gears 10, causing them to rotate synchronously. The two sets of first worms 6 pass through the bracket 2 and are centrally connected to the second worm gear 10. The rotation of the two sets of second worm gears 10 drives the two sets of first worms 6 to rotate. The two sets of first worms 6 disposed on the bottom wall of the bracket 2 are in turn meshed with the two sets of first worm gears 5. The rotation of the first worms 6 further drives the first worm gears 5 to rotate. The first worm gear 5 disposed on the bottom wall of the movable chamber rotates, and a screw 4 is disposed at its upper center, and a screw groove adapted to the screw 4 is disposed below the slide 3. When the first worm gear 5 rotates, the screw 4 rotates accordingly. Since the slide plate 3 cooperates with the screw 4 through the screw groove, the rotation of the screw 4 causes the slide plate 3 to move up and down in the groove along the axial direction of the screw 4.

[0028] In this embodiment, the base 1 is further provided with reinforcing ribs 12 connected to the side walls of the bracket 2 to ensure the supporting stability of the bracket 2.

[0029] During actual use, a notch is provided in the slide groove near one end of the center of the bracket 2, and a connecting beam 15 is provided between the two corresponding groups of slides 3, ensuring that the two groups of slides 3 can cooperate in bearing force when supporting the boiler, thereby enhancing the overall supporting strength of the two groups of slides 3, and avoiding the situation where a single group of slides 3 is subjected to excessive force and deformed, thereby providing stable support for the horizontally placed boiler.

[0030] During actual use, a chamfer 16 is provided below the slide plate 3 so that it can be stably inserted into the slide groove.
