[0002] The boiler in a thermal power plant is equipped with heating surface tubes such as water-cooled walls, superheaters, reheaters and economizers. In the process of building a thermal power plant boiler, these heating surface tubes need to be transported to the corresponding hoisting position before they can be hoisted in the boiler. When transporting the heating surface tubes, due to the heavy weight and large size of these heating surface tubes, existing conventional transport vehicles cannot complete the transportation work. Currently, heavy-duty combined platforms are usually used to transport these heating surface tubes.

[0003] The existing heavy-duty combined platform usually includes a support frame for placing the heating surface pipe row and a plurality of steering wheels fixed at the bottom of the support frame, wherein the steering wheel includes a mounting plate, a mounting frame rotatably arranged at the bottom of the mounting plate, and a roller rotatably arranged on the mounting frame. When using the existing heavy-duty combined platform to transport the heating surface pipe row, the heating surface pipe row needs to be placed on the support frame, and then a plurality of workers push the heavy-duty combined platform to the designated hoisting position. The current environment of the construction site of a thermal power plant is usually more complicated, and workers need to frequently change the moving direction of the heavy-duty combined platform. However, the plurality of steering wheels at the bottom of the existing heavy-duty combined platform are under great pressure, and it is difficult for the plurality of steering wheels to complete the corresponding steering action. Every time the moving direction of the heavy-duty combined platform needs to be changed, many workers need to cooperate with each other and use great force to push the heavy-duty combined platform to enable the plurality of rotating wheels to complete the corresponding steering action, which will increase the labor intensity of the workers. In addition, it takes a lot of time to adjust the moving direction of the heavy-duty combined platform, which will seriously affect the transportation efficiency of the heating surface pipe row. Summary of the invention

[0004] In order to solve the above deficiencies in the prior art, the utility model aims to provide a steering wheel applied to a heavy-load combined platform, so as to reduce the labor intensity of workers and improve transportation efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a steering wheel applied to a heavy-load combination platform, comprising a mounting seat fixedly connected to the heavy-load combination platform, a bracket assembly rotatably connected to the mounting seat and located below the mounting seat, a roller rotatably connected to the bracket assembly, a limit assembly detachably connected to the bracket assembly and capable of limiting the movement of the roller or releasing the restriction on the movement of the roller, and a lifting assembly fixed to the bottom of the mounting seat and capable of adjusting the distance between the bottom of the roller and the ground so that the roller can be separated from the ground or contact the ground.

[0006] As a limitation of the present invention, the bracket assembly is eccentrically arranged below the mounting seat, and the roller is eccentrically arranged on the bracket assembly and the roller is located directly below the mounting seat.

[0007] As another limitation of the present invention, the bracket assembly includes a top plate rotatably connected to a mounting base via a rotating pin member, two vertical plates relatively fixed on both sides of the top plate and located below the top plate, a horizontal connecting shaft fixed between the two vertical plates, and two hanging rods fixed on the two vertical plates; the roller is rotatably connected to the horizontal connecting shaft.

[0008] As a further limitation of the present invention, the bracket assembly further includes at least one reinforcing plate fixed between the two vertical plates.

[0009] As a further limitation of the present invention, the limiting assembly includes two roller limiting components respectively hooked on two hanging rods.

[0010] As a further limitation of the present invention, the jacking assembly includes at least two jack components arranged at the bottom of the mounting seat; the base of the jack components is fixedly arranged at the bottom of the mounting seat.

[0011] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0012] (1) The utility model adopts a structural form that combines a mounting seat, a bracket assembly, a roller, a limit assembly and a jacking assembly, wherein the mounting seat can enable the utility model to be stably fixed on the bottom of the heavy-duty combined platform; the bracket assembly is rotatably connected to the mounting seat so that the roller can realize the steering function; the limit assembly can limit the movement of the roller or release the limit on the movement of the roller. When the roller does not need to move, the movement of the roller can be limited by the limit assembly, which can effectively improve the practicality of the utility model; the jacking assembly can make the roller leave the ground. When the moving direction of the heavy-duty combined platform needs to be changed, the jacking assembly can be used to lift the heavy-duty combined platform. At this time, the roller can be separated from the ground. By rotating the bracket assembly, the roller can be rotated to the required direction. At the same time, the jacking assembly is operated to make the roller contact the ground again to complete the adjustment of the roller direction. The operation of adjusting the roller direction is very simple, which saves time and effort, and can effectively reduce the labor intensity of workers and improve the transportation efficiency of heating surface pipe rows.

[0013] (2) In the present invention, the bracket assembly is eccentrically arranged below the mounting seat, and the roller is eccentrically arranged on the bracket assembly and is located directly below the mounting seat. This makes the force of the present invention more reasonable, the roller can turn more easily when moving, and can better adapt to uneven ground, which can effectively improve the stability and practicality of the structure of the present invention.

[0014] (3) The present invention provides a reinforcing plate between the two vertical plates, which can increase the overall strength of the bracket assembly structure, provide more stable support for the roller, and effectively improve the reliability and stability of the structure of the present invention.

[0015] (4) The utility model has a reasonable structure and strong practicality. The user can choose whether to use the limit assembly to limit the roller according to the actual use needs. When the roller needs to be limited, the two roller limit components can cooperate with each other to achieve the limit of the roller, so that the heavy-load combination platform can be stably placed in the required position. When the roller does not need to be limited, the operation is very simple, and the two roller limit components only need to be hooked on the two hanging rods respectively.

[0016] In summary, the utility model has a reasonable structure, convenient operation and strong practicality. The jacking assembly can lift the heavy-load combined platform to lift the roller off the ground. The roller can be rotated to the required direction by rotating the bracket assembly. At the same time, the jacking assembly is operated to make the roller contact the ground to complete the adjustment of the roller direction. The operation of adjusting the roller direction is very simple, which saves time and effort, and can effectively reduce the labor intensity of workers and improve the transportation efficiency of heating surface pipe rows. The utility model is suitable for installation on a heavy-load combined platform. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted in advance that the number of this embodiment to be used needs to be selected according to the design requirements of the heavy-duty combined platform, and according to the design requirements of the heavy-duty combined platform, multiple embodiments of this embodiment are fixed at corresponding positions at the bottom of the heavy-duty combined platform.

[0031] like Figure 5 , Figure 6 As shown, the bracket assembly 2 includes a top plate 23 rotatably connected to the mounting seat 1 through a rotating pin shaft component, two vertical plates 24 relatively fixed on both sides of the top plate 23 and located below the top plate 23, at least one reinforcing plate 25 fixed between the two vertical plates 24, a horizontal connecting shaft 26 fixed between the two vertical plates 24, and two hanging rods 27 fixed on the two vertical plates 24, wherein the hanging rods 27 are L-shaped rods, the bracket assembly 2 is eccentrically arranged below the mounting seat 1, and the roller 3 is eccentrically arranged on the bracket assembly 2 and the roller 3 is located directly below the mounting seat 1. Specifically, in this embodiment, a reinforcing plate 25 is fixedly provided at the end of the same side of the two vertical plates 24. The rotating pin shaft component includes a hexagonal pin 21 and a hexagonal nut 22 threadedly connected to the bottom of the hexagonal pin 21. As shown Figure 3 , Figure 4As shown, the mounting seat 1 includes a rectangular plate 11 and a cylindrical block 12 fixed at the bottom of the rectangular plate 11. The cylindrical block 12 is located at a position one centimeter to the right of the center of the bottom of the rectangular plate 11. Four fastening bolt holes 14 are provided on the rectangular plate 11 in the mounting seat 1 for matching with four fastening bolts to fix the present embodiment to the bottom of the heavy-duty combined platform. A stepped cylindrical through hole 13 is provided at the position where the cylindrical block 12 is located on the mounting seat 1. The shape and size of the stepped cylindrical through hole 13 are adapted to the shape and size of the hexagonal pin 21 so that the hexagonal pin 21 is rotatably connected to the stepped cylindrical through hole 13. The bottom of the hexagonal pin 21 passes through the top plate 23 in the bracket assembly 2 and is fixed on the top plate 23 by a hexagonal nut 22. After the rotating pin shaft component is assembled, the top surface height of the hexagonal pin 21 in the rotating pin shaft component is lower than the top surface height of the rectangular plate 11 in the mounting seat 1.

[0032] The roller 3 adopts a double-bearing wheel, which is rotatably connected to the horizontal connecting shaft 26. The limiting assembly includes two roller limiting members 4 respectively hooked on two hanging rods 27, and the roller limiting member 4 includes a roller limiting block with an arc surface on one side and a hanging ring fixed on the top of the roller limiting block. The roller limiting block is an iron block, and the outer side of the iron block is provided with an anti-slip rubber layer. The two roller limiting members 4 can be respectively clamped on both sides of the bottom of the roller 3 to achieve the limiting of the roller 3.

[0033] The lifting assembly includes at least two jack components 5 disposed at the bottom of the mounting seat 1, and the base of the jack component 5 is fixedly disposed at the bottom of the mounting seat 1.

The handle of the screw jack can move the screw in the screw jack toward the ground. The two screw jacks in this embodiment cooperate with each other to lift the mounting seat 1 to lift the roller 3 off the ground.

[0034] When the heavy-loaded combined platform needs to adjust the moving direction during use of this embodiment, the direction of the roller 3 needs to be adjusted. The specific method for adjusting the direction of the roller 3 is: simultaneously rotate the operating handles of the two screw jacks until the roller 3 is off the ground, at which time the roller 3 is in a suspended state, and the bracket assembly 2 can be easily rotated to rotate the roller 3 to the required position, and then the operating handles of the two screw jacks are rotated in the opposite direction until the roller 3 is pressed on the ground, at which time the bottoms of the two screw jacks are off the ground.

[0035] When the heavy-load combined platform needs to remain stationary for a long time after moving to the designated position, the roller 3 in this embodiment needs to be limited to prevent the roller 3 from rotating. The method of limiting the rotation of the roller 3 is as follows: Figure 7As shown, the two roller limiting members 4 are removed from the two hanging rods 27 respectively, and then the two roller limiting members 4 are clamped on both sides of the roller 3 to ensure that the two roller limiting members 4 can stably limit the rotation of the roller 3. When the heavy-load combined platform needs to be moved again, the two roller limiting members 4 only need to be re-hanged on the two hanging rods 27 respectively.
