[0026] See Figure 1 、 Figure 2 As shown in [relevant figure numbers] (not provided in the original, assumed to be filled in actual situation), a device for controlling the installation accuracy of a transmission shaft provided by an embodiment of this application includes a connecting seat 10. A positioning through - hole 101 for the transmission shaft 13 to pass through is arranged on the connecting seat 10; at least three support columns 11 are arranged around the connecting seat 10, and the support columns 11 are connected to the connecting seat 10 through a telescopic adjusting crossbar 12.

[0027] The connecting seat 10 is used to connect with the transmission shaft 13 to form a temporary fulcrum when adjusting the installation accuracy of the transmission shaft 13. Exemplarily, a positioning through-hole 101 is provided on the connecting seat 10. During connection, the transmission shaft 13 is passed through the positioning through-hole 101 of the connecting seat 10. At least three support columns 11 for supporting the connecting seat 10 are arranged around the connecting seat 10. Exemplarily, the number of the support columns 11 is four, and the four support columns 11 are circumferentially and evenly arranged around the connecting seat 10. Each support column 11 is connected with the connecting seat 10 through a telescopic adjusting cross bar 12. By controlling the elongation or shortening of the four adjusting cross bars 12, the position of the connecting seat 10 in the horizontal plane can be adjusted.

[0028] See Figure 3 , the method for controlling the installation accuracy of the transmission shaft 13 by using the transmission shaft installation accuracy control device provided by the embodiment of the present application includes: hoisting the transmission shaft 13 to the installation position and installing the lower end of the transmission shaft 13 into the bearing seat 14. During this process, a probe can be used to accurately adjust the position of the lower end of the transmission shaft 13, so as to ensure the installation accuracy of the lower end of the transmission shaft 13; connecting the connecting seat 10 with the transmission shaft 13 and supporting the support columns 11 on the foundation. In this way, the control device composed of the connecting seat 10, the support columns 11 and the adjusting cross bars 12 is used to temporarily support the upper section of the transmission shaft 13. A spirit level is used to measure the verticality of the transmission shaft 13. If the verticality of the transmission shaft 13 does not meet the requirements, the elongation or shortening of the adjusting cross bar 12 is controlled to adjust the horizontal position of the connecting seat 10, and further adjust the verticality of the transmission shaft 13. After the verticality of the transmission shaft 13 meets the requirements, the upper end of the transmission shaft 13 can be installed and fixed, and then the connecting seat 10, the support columns 11 and the adjusting cross bars 12 are removed.

[0029] The transmission shaft installation accuracy control device provided by the embodiment of the present application is used to assist an operator in installing the transmission shaft 13. During the installation process, by only controlling the elongation or shortening of the adjusting cross bar 12, the verticality of the transmission shaft 13 can be quickly and accurately adjusted, thereby ensuring the installation accuracy of the transmission shaft 13. Compared with the prior art, the workload is also reduced and the work efficiency is improved.

[0030] See Figure 1 , Figure 2, the connecting seat 10 includes two oppositely arranged clamping bodies 102. The two clamping bodies 102 are connected by a first connecting structure 103, and a positioning through hole 101 is formed between the two clamping bodies 102. During operation, just place the two clamping bodies 102 on both sides of the transmission shaft 13, and connect the two clamping bodies 102 together through the first connecting structure 103, so that the two clamping bodies 102 clamp the transmission shaft 13, realizing the connection between the connecting seat 10 and the transmission shaft 13. To prevent the clamping body 102 from directly contacting the transmission shaft 13 and damaging the surface of the transmission shaft 13, a rubber pad can also be provided between the clamping body 102 and the transmission shaft 13.

[0031] Exemplarily, the clamping body 102 is integrally an arc-shaped structure. The two ends of the clamping body 102 are respectively connected by a first connecting structure 103. Among them, the first connecting structure 103 is a bolt connection structure. In other embodiments, the clamping body 102 can also be other structures, which are not specifically limited here. Among them, the first connecting structure 103 can include a hinge that hinges one end of the two clamping bodies 102 together, and a bolt connection structure that connects the other ends of the two clamping bodies 102 together.

[0032] See Figure 1 , Figure 2 , the adjusting cross bar 12 includes a first connecting section 121, a second adjusting section 122 and a third connecting section 123; one end of the first connecting section 121 is connected to the support column 11, and one end of the third connecting section 123 is connected to the connecting seat 10; the two ends of the second adjusting section 122 are respectively rotatably connected to the first connecting section 121 and the third connecting section 123, and drive the first connecting section 121 and the third connecting section 123 to approach or move away from each other during the rotation of the second adjusting section 122. Specifically, one end of the third connecting section 123 is connected to the clamping body 102 of the connecting seat 10.

[0033] Exemplarily, one end of the second adjusting section 122 is connected to the first connecting section 121 through a rotary joint, so that the second adjusting section 122 can rotate around its own axis relative to the first connecting section 121. An internal threaded hole extending along its axial direction is provided at the other end of the second adjusting section 122. One end of the third connecting section 123 is inserted into the internal threaded hole of the second adjusting section 122 and is threadedly connected to the internal threaded hole. In this way, when the second adjusting section 122 is rotated, the first connecting section 121 and the third connecting section 123 can approach or move away from each other to control the telescopic movement of the adjusting cross bar 12. In other embodiments, internal threaded holes extending along its axial direction and having opposite thread directions are respectively provided at both ends of the second adjusting section 122. The first connecting section 121 and the third connecting section 123 are respectively threadedly connected to the internal threaded holes at both ends of the second adjusting section 122. In this way, when the second adjusting section 122 is rotated, the first connecting section 121 and the third connecting section 123 can approach or move away from each other.

[0034] To facilitate the rotation of the second adjustment section 122, a handle 124 is provided on the second adjustment section 122. During operation, the operator holds the handle 124 to drive the rotation of the second adjustment section 122. Exemplarily, the handle 124 is a rod perpendicular to the second adjustment section 122, and the number of handles 124 can be one, two, or more than two.

[0035] See Figure 1 , the support column 11 includes a bottom plate 111 and a vertical column 112 disposed on the bottom plate 111, and the adjustment cross bar 12 is connected to the column 112. Specifically, the bottom plate 111 is horizontally disposed, the column 112 is vertically disposed, the lower end of the column 112 is welded to the bottom plate 111, and the upper end of the column 112 is connected to the first connection section 121 of the adjustment cross bar 12. In some embodiments, the adjustment cross bar 12 is horizontally disposed and extends along the radial direction of the positioning through hole 101.

[0036] See Figure 1 , the column 112 is a telescopic structure. By setting the column 112 as a telescopic structure, not only can the height of the connection seat 10 on the transmission shaft 13 be adjusted, but also the verticality of the transmission shaft 13 can be adjusted, improving the flexibility of adjustment. Exemplarily, the column 112 includes a fixed section 113 disposed on the bottom plate 111, and a movable section 114 disposed above the fixed section 113 and threadedly connected to the fixed section 113; the movable section 114 is movably connected to the adjustment cross bar 12 so that the movable section 114 can rotate about its own axis.

[0037] Specifically, the lower end of the fixed section 113 is fixedly connected to the bottom plate 111, an internal threaded hole extending along its axial direction is provided at the upper end of the fixed section 113, the lower end of the movable section 114 is threadedly connected to the internal threaded hole at the upper end of the fixed section 113, and the upper end of the movable section 114 is rotatably connected to the first connection section 121 of the adjustment cross bar 12 through a rotary joint so that the movable section 114 can rotate about its own axis relative to the first connection section 121. During operation, only by rotating the movable section 114, the upper end of the movable section 114 can drive the first connection section 121 to move up or down, thereby achieving the purpose of adjustment. In other embodiments, an internal threaded hole extending along its axial direction can be provided at the lower end of the movable section 114, and the upper end of the fixed section 113 is threadedly connected to the internal threaded hole at the lower end of the movable section 114.

[0038] To facilitate the rotation of the movable section 114, an operation handle 115 is provided on the movable section 114. During operation, the operator holds the operation handle 115 to drive the rotation of the movable section 114. Exemplarily, the operation handle 115 is a rod perpendicular to the movable section 114, and the number of operation handles 115 can be one, two, or more than two.

[0039] The above are only the preferred embodiments of the present application, and do not impose any formal restrictions on the present application. Based on the technical essence of the present application, any simple modifications, equivalent replacements, and improvements made to the above embodiments within the spirit and principles of the present application still fall within the protection scope of the technical solution of the present application.
