Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slewing platforms, and particularly relates to a mounting method for different devices on a slewing platform. BACKGROUND

[0002] The slewing platform of a crane is the installation basis for different devices such as a boom, a cab platform, and a power platform. The slewing platform drives different devices installed thereon to realize rotational movement around the slewing center, so as to adjust the working orientation. In this process, the adjustment is completed by operation in the cab platform. Obviously, the cab platform is the core area of crane operation, and is used by the driver to monitor the device operation and complete the hoisting operation instruction. The position of the cab platform is fixed on the slewing platform, and the operation visual angle is kept stable with the rotation of the boom, so as to ensure that the driver can continuously observe the working environment during hoisting, and at the same time, the power platform provides power support for the slewing process, that is, the power is provided by the driving system, and the brake device is integrated to ensure the stable operation of the crane under complex working conditions. In this way, the power platform provides basic support and mobility, the slewing platform adjusts the hoisting angle, and the two work together to complete the hoisting operation.

[0003] For example, Chinese patent application No. CN202011312367.9, published on January 10, 2023, discloses a modular assembly method for a crane. The base module, the slewing platform module, the triangular frame module, and the boom module are pre-assembled. Guide blocks are welded along the top of the base. After the base module is hoisted above the base, it is welded. After welding is completed, the guide blocks are removed. The slewing platform module is hoisted onto the base module. The inner ring of the slewing bearing is sleeved on the inner side of the cylindrical part by sliding along the guide slope through the lower end of the first bolt of the slewing bearing. The outer ring of the slewing bearing is fixedly connected with the cylindrical part through the second bolt. The truss is hoisted onto the slewing platform. After the support feet of the truss are aligned with the connecting pieces of the slewing platform, the first welding is performed at the process port. After the first welding checks that the truss connection has no error, the second welding is performed on the connection between the support feet of the truss and the connecting pieces of the slewing platform. After the boom module is installed, the winch is threaded with the wire rope. The above document only considers the alignment and installation between the slewing bearing and the slewing platform, and does not consider the installation of the power platform and the cab platform. However, due to the different loads of the cab platform and the power platform, different bending moments will be generated on both sides of the slewing platform during installation on the slewing platform, which will affect the transmission effect and service life of the slewing platform, and thus the reliability of the cab platform and the power platform assembly will affect the reliability of the slewing of the slewing platform. SUMMARY

[0004] The purpose of this invention is to provide a method for installing different devices on a rotary platform. By adjusting the installation position, the different bending moments experienced by the rotary platform can be effectively offset, thereby improving the transmission effect and service life of the rotary platform and achieving high assembly precision.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for installing different equipment on a slewing platform, wherein the cab platform and the power platform are installed on the slewing platform; Includes the following steps: S1 takes the right side of the rotary platform as the reference plane, and welds a splicing flange assembly one on the upper side of the rotary platform so that the axis of the splicing flange assembly one coincides with the reference plane. Then, another splicing flange assembly one is welded on the upper side of the rotary platform at a preset interval d, and the axis of the splicing flange assembly one is set parallel to the axis of the other splicing flange assembly one. S2 welds a splicing flange assembly two at a preset distance a from the reference plane on the lower side of the rotary platform, so that the axis of the splicing flange assembly two is parallel to the reference plane. Then, another splicing flange assembly two is welded on the lower side of the rotary platform at a preset distance d, and the axis of the first splicing flange assembly two is set parallel to the axis of the second splicing flange assembly two. S3 welds two first mounting flanges and two second mounting flanges on both sides of the cab platform, and the distance between the two first mounting flanges and the two second mounting flanges is equal to the spacing d. S4 lifts the cab platform so that the first through hole of the first mounting flange welded on the cab platform is aligned with the third through hole of the splicing flange assembly one. After the locking piece passes through the first through hole and the third through hole, the cab platform is fixed to the upper side of the slewing platform. S5 lifts the power platform so that the second through hole of the second mounting flange welded on the power platform is aligned with the fourth through hole of the splicing flange assembly two. After the locking piece passes through the second through hole and the fourth through hole, the power platform is fixed to the lower side of the rotary platform, and the splicing flange assembly two and the splicing flange assembly one are staggered.

[0006] The above method ensures that the two splicing flange assemblies welded to the side of the slewing platform are parallel to each other and both parallel to the right side of the slewing platform. This allows the cab platform, once fixedly installed on the slewing platform, to maintain a parallel configuration to meet the operational requirements of the cab platform. Simultaneously, it ensures that the two splicing flange assemblies welded to the lower side of the slewing platform are parallel to each other and both parallel to the right side of the slewing platform. This allows the power platform, once fixedly installed on the slewing platform, to maintain a parallel configuration. By setting different distances between the first and second splicing flange assemblies and the right side of the slewing platform—that is, by creating a staggered arrangement between the first and second splicing flange assemblies on the upper and lower sides of the slewing platform—the bending moments on the relative positions of the upper and lower sides of the slewing platform can be effectively offset. This reduces the tendency of the slewing platform to tilt due to the different loads on the cab platform and the power platform, thereby improving the transmission efficiency and service life of the slewing platform.

[0007] Furthermore, the splicing flange assembly includes a first connecting plate, a first stiffening plate, and a first flange, wherein the first flange is provided with two or more third through holes. The first splicing flange assembly includes a second connecting plate, a second stiffening plate, and a second flange, with the second flange having two or more fourth through holes.

[0008] The above configuration facilitates the connection of the first flange to the first connecting plate and the first stiffening plate, thereby connecting the first connecting plate and the first stiffening plate to the upper side of the rotary platform. It also facilitates the connection of the second flange to the second connecting plate and the second stiffening plate, thereby connecting the second connecting plate and the second stiffening plate to the lower side of the rotary platform, thus improving the connection stability of the first flange and the second flange.

[0009] Furthermore, the other splicing flange assembly includes a first and second connecting plate, a first and second stiffening plate, and a first and second flange, wherein the first and second flange is provided with two or more third through holes; Another splicing flange assembly includes a second connecting plate, a second stiffening plate, and a second flange, with the second flange having two or more fourth through holes.

[0010] The above configuration facilitates the connection of the first and second flanges to the first and second connecting plates and the first and second stiffening plates, thereby connecting the first and second connecting plates and the first and second stiffening plates to the upper side of the rotary platform. It also facilitates the connection of the second and second flanges to the second and second connecting plates and the second and second stiffening plates, thereby connecting the second and second connecting plates and the second and second stiffening plates to the lower side of the rotary platform, thus improving the connection stability of the first and second flanges.

[0011] Furthermore, the locking assembly includes a fixing member, a first locking member and a second locking member that match the fixing member.

[0012] The above configuration facilitates the fixing of the cab platform and the power platform onto the slewing platform after the first and second locking components are threadedly connected to the fixing components.

[0013] Furthermore, step S1 includes steps S1.1 to S1.2. S1.1 On the upper side of the rotary platform, align the center line of the first connecting plate with the reference surface, then weld one end of the first connecting plate to the upper side of the rotary platform, then align the center line of the first stiffening plate with the reference surface, and weld the first stiffening plate to the first connecting plate and the upper side of the rotary platform respectively, then align the axis of the first flange with the reference surface, and weld the first flange to the other end of the first connecting plate and the first stiffening plate. S1.2 Draw a first reference line parallel to the axis of the first flange on the upper side of the rotary platform at a preset interval d, so that the center line of the first and second connecting plates coincides with the first reference line. Then, weld one end of the first and second connecting plates to the upper side of the rotary platform, and the first and second connecting plates are on the same straight line. Next, align the center line of the first and second stiffening plates with the first reference line, and weld the first and second stiffening plates to the first and second connecting plates and the upper side of the rotary platform respectively. Then, align the axis of the first and second flanges with the first reference line, and weld the first and second flanges to the other end of the first and second connecting plates and the first and second stiffening plates.

[0014] The above settings ensure that the first connecting plate, the first and second connecting plates are perpendicular to the upper side of the rotary platform and are on the same straight line. At the same time, they ensure that the first stiffening plate and the first and second stiffening plate, which are respectively welded to the first connecting plate and the first and second connecting plates, are perpendicular to the upper side of the rotary platform. This ensures that the welded first flange and the first and second flange are on the same straight line and parallel to the upper side of the rotary platform.

[0015] Furthermore, step S2 includes steps S2.1 to S2.2. S2.1 Draw a second reference line on the lower side of the rotary platform at a preset distance a from the reference plane. Align the center line of the second connecting plate with the second reference line. Then weld one end of the second connecting plate to the lower side of the rotary platform. Next, align the center line of the second stiffening plate with the second reference line. Weld the second stiffening plate to the second connecting plate and the lower side of the rotary platform respectively. Then align the axis of the second flange with the second reference line. Weld the second flange to the other end of the second connecting plate and the second stiffening plate. S2.2 Draw a third reference line parallel to the axis of the second flange on the lower side of the rotary platform at a preset interval d, so that the center line of the second connecting plate coincides with the third reference line. Then, weld one end of the second connecting plate to the lower side of the rotary platform, and the second connecting plate and the second connecting plate are on the same straight line. Next, align the center line of the second stiffening plate with the third reference line, and weld the second stiffening plate to the second connecting plate and the lower side of the rotary platform respectively. Then, align the axis of the second flange with the third reference line, and weld the second flange to the other end of the second connecting plate and the second stiffening plate.

[0016] The above settings ensure that the second connecting plate and the second connecting plate are perpendicular to the lower side of the rotary platform and are on the same straight line. At the same time, they ensure that the second stiffening plate and the second stiffening plate welded to the second connecting plate and the second connecting plate are perpendicular to the lower side of the rotary platform. This ensures that the welded second flange and the second flange are on the same straight line and parallel to the lower side of the rotary platform.

[0017] Furthermore, in step S3, the distance between the two first mounting flanges is equal to the preset spacing d and they are on the same horizontal straight line; the distance between the two second mounting flanges is equal to the preset spacing d and they are on the same horizontal straight line.

[0018] The above configuration facilitates the connection of the two first mounting flanges with the first flange and the first second flange, respectively, to secure the cab platform; it also facilitates the connection of the two second mounting flanges with the second flange and the second second flange, respectively, to secure the power platform.

[0019] Furthermore, in step S4, after "aligning the first through hole with the third through hole", the first locking member and the second locking member are threadedly connected to the fixing member after the fixing member passes through the first through hole and the third through hole in sequence, thereby fixing the first mounting flange with the first flange and the first mounting flange with the second flange respectively.

[0020] The above setup allows for the fixed installation of the cab platform on the slewing platform by connecting the two first mounting flanges to the first flange and the first second flange respectively.

[0021] Furthermore, in step S5, after the second through hole and the fourth through hole are aligned, the first locking member and the second locking member are threadedly connected to the fixing member through the fasteners passing through the second through hole and the fourth through hole in sequence, thereby fixing the second mounting flange to the second first flange and the second mounting flange to the second second flange respectively.

[0022] The above setup allows the power platform to be fixedly installed on the slewing platform by connecting the two second mounting flanges to the second first flange and the second second flange respectively. Attached Figure Description

[0031] Two splicing flange assemblies are provided on the lower side a5 of the rotary platform, namely a first splicing flange assembly and a second splicing flange assembly. The first splicing flange assembly includes a second connecting plate a12, a second stiffening plate a13, and a second flange a14. The second flange a14 has two or more fourth through holes. The second splicing flange assembly includes a second connecting plate a15, a second stiffening plate a16, and a second flange a17. The second flange a17 has two or more fourth through holes to facilitate the connection of the second flange a14 to the second connecting plate a15 and the second stiffening plate a16. This allows the second connecting plate a15 and the second stiffening plate a16 to be connected to the lower side a5 of the rotary platform, thereby improving the connection stability of the first flange a11 and the second flange a17.

[0032] In this embodiment, the upper side a4 of the rotary platform and the lower side a5 of the rotary platform are arranged parallel to each other and both are arranged perpendicular to the right side a20 of the rotary platform.

[0033] In this embodiment, the locking assembly includes a fixing member, a first locking member and a second locking member that match the fixing member, so that after the first locking member and the second locking member are threadedly connected to the fixing member, the cab platform a2 and the power platform a3 are respectively fixed on the slewing platform a1. The fixing member is a bolt, and the first locking member and the second locking member are both nuts.

[0034] The assembly method includes the following specific steps: S1. Using the right side a20 of the rotary platform as the reference plane, weld a splicing flange assembly 1 on the upper side a4 of the rotary platform, so that the axis of the splicing flange assembly 1 coincides with the reference plane. Then, weld another splicing flange assembly 1 on the upper side a4 of the rotary platform at a preset interval d, and set the axis of the first splicing flange assembly 1 parallel to the axis of the second splicing flange assembly 1. Specifically, it includes steps S1.1 to S1.2.

S1.2 Draw a first reference line a22 parallel to the axis of the first flange a8 on the upper side a4 of the rotary platform at a preset interval d, so that the center line of the first second connecting plate a9 coincides with the first reference line a22. Then, weld one end of the first second connecting plate a9 to the upper side a4 of the rotary platform, and the first first connecting plate a6 and the first second connecting plate a9 are on the same straight line. Next, align the center line of the first second stiffening plate a10 with the first reference line a22, and weld the first second stiffening plate a10 to the first second connecting plate a9 and the upper side a4 of the rotary platform respectively. Then, align the axis of the first second flange a11 with the first reference line a22, and weld the first second flange a11 to the other end of the first second connecting plate a9 and the first second stiffening plate a10.

[0035] S2. A second splicing flange assembly is welded on the lower side a5 of the rotary platform at a predetermined distance a from the reference plane, such that the axis of the second splicing flange assembly is parallel to the reference plane. Then, another second splicing flange assembly is welded on the lower side a5 of the rotary platform at a predetermined distance d, and the axis of the second splicing flange assembly is parallel to the axis of the other second splicing flange assembly. Specifically, this includes steps S2.1 to S2.2. In this embodiment, the predetermined distance a is one-quarter of the predetermined distance d. The predetermined distance d is less than the length of the upper side a4 or the lower side a5 of the rotary platform. S2.1 On the lower side a5 of the rotary platform, at a position a preset distance a from the reference plane, make a second reference line. Align the center line of the second connecting plate a12 with the second reference line a23. Then weld one end of the second connecting plate a12 to the lower side a5 of the rotary platform. Next, align the center line of the second stiffening plate a13 with the second reference line a23. Weld the second stiffening plate a13 to the second connecting plate a12 and the lower side a5 of the rotary platform respectively. Then align the axis of the second flange a14 with the second reference line a23. Weld the second flange a14 to the other end of the second connecting plate a12 and the second stiffening plate a13. S2.2 Draw a third reference line a24 parallel to the axis of the second flange a14 on the lower side a5 of the rotary platform at a preset interval d, so that the center line of the second connecting plate a15 coincides with the third reference line a24. Then, weld one end of the second connecting plate a15 to the lower side a5 of the rotary platform, and the second connecting plate a12 and the second connecting plate a15 are on the same straight line. Next, align the center line of the second stiffening plate a16 with the third reference line a24, and weld the second stiffening plate a16 to the second connecting plate a15 and the lower side a5 of the rotary platform respectively. Then, align the axis of the second flange a17 with the third reference line a24, and weld the second flange a17 to the other end of the second connecting plate a15 and the second stiffening plate a16.

[0036] S3 welds two first mounting flanges a25 on one side of the cab platform a2, such that the distance between the two first mounting flanges a25 is equal to the preset spacing d and they are on the same horizontal straight line; then welds two second mounting flanges a26 on one side of the power platform a3, such that the distance between the two second mounting flanges a26 is equal to the preset spacing d and they are on the same horizontal straight line.

[0037] S4 lifts the cab platform a2, aligning the first through hole a18 of the first mounting flange a25 welded to the cab platform a2 with the third through hole of the splicing flange assembly one. After the fasteners pass through the first through hole a18 and the third through hole in sequence, the first locking member and the second locking member are threadedly connected to the fasteners. The first mounting flange a25 is fixed to the first flange a8 and the first flange a11 respectively, and the cab platform a2 is fixed to the upper side a4 of the slewing platform, thus completing the installation of the cab platform a2.

[0038] S5 lifts the power platform a3, aligning the second through hole a19 of the second mounting flange a26 welded to the power platform a3 with the fourth through hole of the splicing flange assembly two. After the fasteners pass through the second through hole a19 and the fourth through hole in sequence, the first locking member and the second locking member are threadedly connected to the fasteners. The second mounting flange a26 and the second first flange a14, and the second mounting flange a26 and the second second flange a17 are fixed respectively. The power platform a3 is then fixed to the lower side a5 of the rotary platform, completing the installation of the power platform a3.

[0039] The working principle of this invention is as follows: First, two splicing flange assemblies are welded to the side of the slewing platform, so that the two splicing flange assemblies are arranged in parallel and parallel to the right side of the slewing platform. This ensures that the cab platform, after being fixedly installed on the slewing platform, can maintain a parallel arrangement with the slewing platform, thus meeting the working requirements of the cab platform on the slewing platform. Then, two splicing flange assemblies are welded to the lower side of the slewing platform, so that the two splicing flange assemblies are arranged in parallel and parallel to the right side of the slewing platform. This ensures that the power platform, after being fixedly installed on the slewing platform, can maintain a parallel arrangement with the slewing platform. By setting the distances of the splicing flange assemblies 1 and 2 from the right side of the slewing platform to be different, that is, the splicing flange assemblies 1 and 2 located on the upper and lower sides of the slewing platform are staggered, the bending moment on the upper and lower sides of the slewing platform can be effectively offset, thereby reducing the tendency of the slewing platform to tilt due to the different loads of the cab platform and the power platform, thus improving the transmission effect and service life of the slewing platform.
