Description

Technical Field

[0001] The invention relates to the technical field of crane equipment, and in particular to an installation method of a crane workpiece and a processing tooling and a crane workpiece processing method. Background Art

[0002] As an important component of the crane, the slewing mechanism enables the rotating part of the crane to rotate on the horizontal plane, thus ensuring that the goods can be smoothly moved from one place to another. Since the slewing mechanism needs to bear a heavy load during operation, its processing must maintain extremely high precision, and the center of the slewing mechanism needs to be processed with a hole by external processing equipment. At the same time, due to the large size and heavy weight of the slewing mechanism, a fixture is required to fix the slewing mechanism. Therefore, there are requirements for the processing accuracy of the fixture, and there are also requirements when the fixture clamps the slewing mechanism for processing.

[0003] For example, the patent application number is 202211586761.0 and the publication date is 2023.03.03. The patent document discloses a processing and positioning tool for the side hole of a slewing bearing, including a support platform, a liquid storage tank for storing cutting fluid is provided on one side of the support platform, an annular support frame is installed on the support platform, and a support rod is provided on the support platform and on one side of the annular support frame, a support swivel is rotatably connected to the annular support frame, a transmission annular cylinder is installed on the support swivel, and a support cylinder is installed on the inner periphery of the transmission annular cylinder. The support cylinder is provided with four and is evenly distributed at equal angles, a telescopic cylinder is movably sleeved in the support cylinder, and a clamping plate is fixedly connected to one end of the telescopic cylinder located on the outer side of the support cylinder, a second liquid guide cylinder is provided above the middle part of the support swivel, and a first liquid guide cylinder is provided below the middle part of the support swivel. The first liquid guide cylinder guides the cutting fluid carrying cutting debris into the lower side of the filter partition, cyclically collects the debris to avoid accumulation and pollution, and is suitable for various slewing bearings and their drilling distributions.

[0004] The above documents synchronously move the telescopic cylinder and synchronously push the slewing bearing through the clamping plate, so as to stably clamp the slewing bearing. A spring rod is arranged between the clamping block and the clamping plate. During the long-term clamping process, the elastic deformation of the spring rod may change, resulting in the clamping block not being able to stretch into place during clamping, and the clamping block not being able to contact the slewing mechanism in place, so that the slewing mechanism may be offset during the clamping process, and the axis of the slewing mechanism is inconsistent with the axis of the supporting swivel. Moreover, it only limits the position in the horizontal direction of the installation surface, and cannot accurately ensure the limit in the vertical direction. In addition, for different types of slewing platforms, it is impossible to accurately install the corresponding tooling according to the different sizes of different types of slewing platforms, which makes the installation accuracy high, and the tooling structure is complex and the installation is complex. Summary of the invention

[0005] The invention provides a method for installing a crane workpiece and a processing tool and a method for processing a crane workpiece, which can form a tool according to the sizes of different rotary platforms, and the processing tool has high reliability and good accuracy in processing the workpiece. In order to achieve the above-mentioned purpose, the technical solution provided by the present invention on one hand is: a method for installing a crane workpiece and a processing tool, which is used to place a slewing mechanism, the slewing mechanism includes a slewing mechanism body and a slewing panel arranged at one end of the slewing mechanism body, a support is arranged at the other end of the slewing body, and assembly holes arranged at intervals along the circumferential direction are arranged on the slewing panel. The processing tool includes a base, and limit plates and support columns are arranged on both sides of the base. Limit grooves are arranged on the limit plates, and the support columns are also provided with an adjustment mechanism. The adjustment mechanism includes an adjustment rod, and the adjustment rod is rotatably connected to the support column, including the following steps: S1 determines the parameters of the slewing mechanism; the slewing mechanism parameters include the distance s1 from one end to the other end of the slewing mechanism body, the height difference d1 between the bottom of the slewing mechanism and the bottom of the support, and the height difference d2 between one side of the slewing mechanism body and the same side of the slewing panel; S2 determines the distance between the upper end of the limit plate and the upper end of the support column according to the height difference d1 between the bottom of the slewing mechanism and the bottom of the support, determines the depth of the upper limit groove of the limit plate according to the height difference d2 between one side of the slewing mechanism body and the same side of the slewing panel, and processes the limit plate and the support column; determines the distance between the support column and the limit plate on the base according to the distance s1 from one end to the other end of the slewing mechanism body, fixes the limit plate and the support column on the base, installs a second lifting ear at the upper end of the support column, and sets a first lifting ear on both sides of the lower part of the limit plate; S3 hoists the rotary mechanism onto the processing tooling.

[0006] The above settings first measure the rotating mechanism to determine the parameters of the rotating mechanism, first determine the distance between the upper end of the limit plate and the upper end of the support column according to the height difference d1 between the bottom of the rotating mechanism and the bottom of the support, and determine the depth of the upper limit groove of the limit plate according to the height difference d2 between one side of the rotating mechanism body and the same side of the rotating panel. In this way, different limit plates and support columns can be accurately selected according to different rotating platforms, and then the distance between the support column and the limit plate on the base is determined according to the distance s1 from one end to the other end of the rotating body to install the support column and the limit plate, so that the workpiece tooling after installation can reliably limit the horizontal direction of the rotating mechanism through the limit plate and the support column, and then limit the vertical direction of the rotating platform through the support and the top of the support column. This can further ensure the accuracy after installation and the reliability of the limit after installation, and only requires two to install the support column and the limit plate on the mounting seat, and then install the ears on the limit plate and the support column. The installation method is simple and reliable.

[0007] Furthermore, the limiting panel is provided with a limiting hole corresponding to the assembly hole, the limiting groove is an arc groove, and the arc groove is matched with the rotary mechanism body. In step S1, the parameters of the rotary mechanism also include: the diameter d3 of the rotary mechanism body, the height difference d2 between one side of the rotary mechanism body and the same side of the rotary panel, and the size and distribution position of the assembly holes on the rotary panel; Step S2 also includes: determining the curvature and depth of the limit groove according to the diameter d3 of the rotating panel and the height difference d2 between one side of the rotating mechanism body and the same side of the rotating panel, and processing the mounting hole corresponding to the size of the assembly hole at the corresponding position of the limit plate according to the size and position of the assembly hole on the rotating panel.

[0008] According to the above arrangement, the contact area between the limit plate and the rotating structure body can be increased through the arc-shaped limit groove, and the limit hole is set on the rotating panel to further ensure the reliability of installation after installation through the installation hole and the assembly hole, and the curvature of the limit groove can be determined according to the diameter d3 of the rotating mechanism body, and then the depth of the limit groove can be determined according to the height difference d2 between one side of the rotating mechanism body and the same side of the rotating panel, so that the processing of the limit groove can be determined, and the position and size of the installation hole are determined according to the assembly hole, so that the processing is convenient and reliable.

[0009] Furthermore, after step S3, the following steps are also included: S4 screws the fastener between the assembly hole and the mounting hole; S5: using a square ruler to measure the horizontality of the rotary mechanism. If the rotary mechanism is in a horizontal state, proceed to step S7; if it is not in a horizontal state, proceed to step S6; S6 rotates the adjustment rod to make the slewing mechanism in a horizontal state; S7 tightens the fasteners.

[0010] With the above arrangement, the slewing mechanism is placed between the limit plate and the support column by means of a lifting device. After placement, it is leveled by means of an adjusting rod. The slewing mechanism is fixed on the limit plate and connected to the slewing mechanism as a whole by means of a processing tool. The processing tool and the slewing mechanism enter the processing procedure as a whole, thus reducing the subsequent leveling time.

[0011] Furthermore, in step S4, the fastener is screwed into between the assembly hole and the mounting hole for pre-fixation.

[0012] With the above arrangement, when the slewing mechanism is placed on the limit plate and the support column, the fasteners are not tightened first, but screwed in to leave adjustment positions for subsequent leveling.

[0013] Further, in step S6, the adjusting rod is rotated so that the adjusting rod moves upward or downward relative to the supporting rod.

[0014] In the above arrangement, an adjusting rod is provided on the support column. When adjusting, the adjusting rod can be rotated. On the one hand, the adjusting rod can be used to limit the vertical direction of the rotating mechanism in the processing tooling. On the other hand, the adjusting rod can also be used to limit the horizontal direction of the rotating mechanism so that the rotating mechanism is in a horizontal state. During the leveling process, a square is used to measure the horizontal position of the rotating mechanism.

[0015] Another aspect of the present invention provides a crane workpiece processing method, comprising the following steps: S1 determines the parameters of the slewing mechanism; the slewing mechanism parameters include the distance s1 from one end to the other end of the slewing mechanism body, the height difference d1 between the bottom of the slewing mechanism and the bottom of the support, and the height difference d2 between one side of the slewing mechanism body and the same side of the slewing panel; S2 determines the distance between the upper end of the limit plate and the upper end of the support column according to the height difference d1 between the bottom of the slewing mechanism and the bottom of the support, determines the depth of the upper limit groove of the limit plate according to the height difference d2 between one side of the slewing mechanism body and the same side of the slewing panel, and processes the limit plate and the support column; determines the distance between the support column and the limit plate on the base according to the distance s1 from one end to the other end of the slewing mechanism body, fixes the limit plate and the support column on the base, installs a second lifting ear at the upper end of the support column, and sets a first lifting ear on both sides of the lower part of the limit plate; S3 hoists the rotary mechanism onto the processing tooling; S8 uses lifting equipment to lift the processing tooling horizontally to the working platform; S9 uses a pressure plate to hold down the base and process the through hole of the rotary mechanism body; S10 removes the pressure plate and uses the lifting equipment to lift the processing tooling horizontally to the next process.

[0016] With the above arrangement, the distance between the upper end of the limit plate and the upper end of the support column is first determined according to the height difference d1 between the bottom of the slewing mechanism and the bottom of the support, and the depth of the upper limit groove of the limit plate is determined according to the height difference d2 between one side of the slewing mechanism body and the same side of the slewing panel. In this way, different limit plates and support columns can be accurately selected according to different slewing platforms. Then, the distance between the support column and the limit plate on the base is determined according to the distance s1 from one end to the other end of the slewing body, and the support column and the limit plate are installed, so that the workpiece fixture after installation can reliably perform water level control on the slewing mechanism through the limit plate and the support column. The horizontal direction is limited, and then the vertical direction of the slewing platform is limited through the support and the top of the support column. This can further ensure the accuracy after installation and the reliability of the limit after installation, and only requires two support columns and limit plates to be installed on the mounting seat, and then the lifting ears are installed on the limit plate and the support column. The installation method is simple and reliable. At the same time, during processing, the pressure plate is first pressed on the base to ensure the reliability of the base during processing, and then the through hole is processed on the slewing mechanism body. During the processing, since the slewing mechanism is connected to the limit plate, the slewing mechanism is stably placed on the limit plate and the support column.

[0017] Furthermore, after step S3, the following steps are also included: S4 screws the fastener between the assembly hole and the mounting hole; S5: using a square ruler to measure the horizontality of the rotary mechanism. If the rotary mechanism is in a horizontal state, proceed to step S7; if it is not in a horizontal state, proceed to step S6; S6 rotates the adjustment rod to make the slewing mechanism in a horizontal state; S7 tightens the fasteners.

[0018] With the above arrangement, the slewing mechanism is placed between the limit plate and the support column by means of a lifting device. After placement, it is leveled by means of an adjusting rod. The slewing mechanism is fixed on the limit plate and connected to the slewing mechanism as a whole by means of a processing tool. The processing tool and the slewing mechanism enter the processing procedure as a whole, thus reducing the subsequent leveling time.

[0019] Furthermore, in step S4, the fastener is screwed into between the assembly hole and the mounting hole for pre-fixation.

[0020] With the above arrangement, when the slewing mechanism is placed on the limit plate and the support column, the fasteners are not tightened first, but screwed in to leave adjustment positions for subsequent leveling.

[0021] Further, in step S6, the adjusting rod is rotated so that the adjusting rod moves upward or downward relative to the supporting rod.

[0022] In the above arrangement, an adjusting rod is provided on the support column. When adjusting, the adjusting rod can be rotated. On the one hand, the adjusting rod can be used to limit the vertical direction of the rotating mechanism in the processing tooling. On the other hand, the adjusting rod can also be used to limit the horizontal direction of the rotating mechanism so that the rotating mechanism is in a horizontal state. During the leveling process, a square is used to measure the horizontal position of the rotating mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] According to the parameters obtained in step S1, the height and curvature of the limit plate 2 are confirmed, and the mounting hole 22 is set on the limit plate 2 according to the size of the assembly hole 4121. In step S1, it is confirmed that the size and position of the assembly hole 4121 can be obtained by measuring the size and distribution position of the assembly hole 4121 on the outside 412 of the rotary mechanism body, so that the assembly hole 4121 matches the mounting hole 22.

The height difference d1 between the bottom height of the rotating mechanism 4 and the bottom height of the support 42 can be obtained. The height difference between the support column 3 and the limiting plate 2 can be obtained. The height difference d2 between the inner side 411 of the rotating mechanism body and the outer side of the rotating mechanism can be obtained to obtain the groove depth of the limiting groove of the limiting plate 2, so that the outer side of the rotating mechanism body 41 does not contact the base 1; the diameter d3 of the inner side 411 of the rotating mechanism body can be measured to obtain the corresponding arc structure of the limiting plate 2, and then the limiting plate 2 and the support column 3 are processed; Hoist the slewing mechanism 4 onto the base 1, screw the fastener 23 between the assembly hole 4121 and the mounting hole 22, and use a square ruler to measure the horizontality of the slewing mechanism 4.
