Description

Technical Field

[0001] The utility model relates to the technical field of internal component assembly, and particularly relates to an assembly mechanism for large internal components. Background Art

[0002] Due to the large volume of some large internal components, the requirements for assembly and installation accuracy are too high. During the hoisting process, the components may be damaged or deformed during transportation, making it difficult to directly hoist them to the designated position.

[0003] The traditional assembly method is to install the internal component by hoisting it into the shell. This method is not suitable for directly hoisting large internal components (such as large heat exchange tube bundles) for assembly. Since the heat exchange tube bundle has a large volume, it is difficult to directly hoist it to the designated position. If the positioning is inaccurate or the installation method is improper, it will lead to assembly deviation, affecting the stability and performance of the overall structure. Directly hoisting the heat exchange tube bundle may also cause deformation or damage to the components, affecting the assembly effect.

[0004] Therefore, it is necessary to invent an assembly mechanism for large internal components to solve the above problems. Content of the Utility Model

[0005] To solve the deficiencies of the prior art, the purpose of the utility model is to provide an assembly mechanism for large internal components, which solves the problems that in the actual use process, due to the large volume of the heat exchange tube bundle, it is difficult to directly hoist it to the designated position. If the positioning is inaccurate or the installation method is improper, it will lead to assembly deviation, affecting the stability and performance of the overall structure.

Hoists are arranged on both sides of the support shaft for pulling the support roller seat to slide along the roller track.

[0008] As a preferred solution of the utility model, a base is slidably arranged at the top end of the roller track, and the traction end of the hoist is detachably connected to the base.

[0009] As a preferred solution of the utility model, a plurality of installation grooves are formed on the inner side surface of the base, and a telescopic component is arranged inside the plurality of installation grooves. The telescopic end of the telescopic component penetrates and extends to the outside of the base.

Detailed implementation manners

[0021] The present utility model will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0022] The present utility model provides an assembly mechanism for a large inner member as shown in Figures 1-4 Figure, including a traveling crane 3 for lifting the outer housing 6 and a support shaft 1 for supporting and fixing the inner member body 7. A plurality of roller tracks 4 are provided at the bottom end of the support shaft 1. A support roller seat 9 for supporting the outer housing 6 and adjusting the relative height position of the outer housing 6 is slidably provided at the top end of the roller track 4. Hoists 2 for pulling the support roller seat 9 to slide along the roller track 4 are provided on both sides of the support shaft 1. The inner member body 7 can first be installed on the outside of the support shaft 1 through the support roller seat 9, so that the axis direction of the inner member body 7 is in a horizontal state, which is convenient for subsequent installation and assembly.

[0023] A base 5 is slidably provided at the top end of the roller track 4. The traction end of the winch 2 is detachably connected to the base 5. By pulling the base 5 by the winch 2, the purpose of driving the outer housing 6 to move slowly is achieved, and large jitters during the movement are avoided, which may affect the assembly effect with the inner member body 7.

[0024] A plurality of mounting grooves 12 are opened on the inner side surface of the base 5. A telescopic assembly 13 is provided inside the plurality of mounting grooves 12. The telescopic end of the telescopic assembly 13 penetrates and extends to the outside of the base 5. By using a plurality of telescopic assemblies 13 in combination, the purpose of controlling the lifting height of the support plate 8 and controlling the support plate 8 to tilt to one side is achieved, so as to achieve the effect of adjusting the relative position of the outer housing 6, thereby improving the assembly accuracy.

[0025] The top end of the telescopic assembly 13 is rotatably connected to a support plate 8. The support roller seat 9 is located at the top end of the support plate 8. A plurality of connecting blocks 14 rotatably connected to the extending end of the telescopic assembly 13 are provided at the bottom end of the support roller seat 9. Through the connection between the connecting block 14 and the telescopic assembly 13, the support plate 8 is relatively stable during the tilting process, and large jitters are avoided from damaging the inner member body 7, thereby affecting the product effect.

[0026] Two support plates 8 are provided at the top of the base 5. The support plates 8 are symmetrically arranged at the top of the base 5. The telescopic assemblies 13 are respectively located at the corners of the bottom ends of the support plates 8. Two guiding grooves 16 are formed at the top of the support plates 8. A rotatable threaded rod 17 is arranged at the central position of the support plates 8. The independent arrangement of the two support plates 8 enables the axial direction of the outer shell 6 or the inner member body 7 to be adjusted horizontally through their inclination, thereby improving the assembly accuracy.

[0027] The support roller seat 9 slides inwards or outwards through the rotation of the guiding grooves 16 and the threaded rod 17. A plurality of rotatable swing seats 15 are arranged at the top of the support roller seat 9. Support roller drums 10 for supporting the outer shell 6 are arranged at both ends of the swing seat 15. The purpose of arranging a plurality of support roller drums 10 is to ensure that when the support plate 8 is inclined at any angle, the support roller drums 10 can be brought into contact with the end face of the outer shell 6 by adjusting the threaded rod 17, thereby reducing the generation of errors.

[0028] One or more of the support roller drums 10 in the swing seat 15 are provided with a rotation assembly 11 for adjusting the rotation angle of the outer shell 6. The arrangement of the rotation assembly 11 can adjust the angle of the outer shell 6, making it easier and more accurate to assemble the outer shell 6 and the inner member body 7.

[0029] In this utility model, the inner member is fixedly arranged on the support shaft 1 to keep it stationary. Then, the outer shell 6 is hoisted to the top of the support roller seat 9 by the hoist 3. By adjusting the lifting height of the telescopic assembly 13 and the relative position of the support roller seat 9, the outer shell 6 is adjusted to a suitable assembly position. The base 5 is moved by the winch 2, so that the outer shell 6 slowly moves towards the direction where the inner member body 7 is located. The rotation of the support roller drum is controlled by the rotation assembly 11 to adjust the angle of the outer shell 6. By measuring parameters such as clearance data in advance, it is avoided that the inner member body 7 is damaged during the process of feeding the outer shell 6 inwards, ensuring the assembly accuracy. By installing the inner member with this mechanism, the problems that the inner member is difficult to hoist and assemble are effectively avoided. By adjusting the support roller seat, its positioning is more accurate, reducing the assembly deviation.

[0030] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
