The frame is a segmented structure, including a standard frame that cooperates with the lifting and running mechanisms of the crane trolley. A first adjusting frame is detachably connected to one side of the standard frame; a second adjusting frame is detachably connected to the other side of the standard frame. A bracket is provided on the outer top surface of the standard frame to support and fix components such as the crane trolley motor, brake, and reducer, ensuring that the output shaft axes of the motor, brake, and reducer located on the upper part of the standard frame are in the same plane.

Description

Technical Field

[0001] This invention relates to the field of standardized design technology, and in particular to a standardized design structure and method for a large-tonnage parametric customized crane frame. Background Technology

[0002] The mechanical components of a crane trolley mainly consist of three parts: the hoisting mechanism, the traveling mechanism, and the frame. The hoisting mechanism is responsible for lifting heavy objects to a certain height, the traveling mechanism supports the movement of the trolley, and the frame supports both the hoisting and traveling mechanisms.

[0003] With the development of the crane industry, the parametrically customized design of large-tonnage crane trolleys in industries such as metallurgy and coking is now moving towards standardization and modularization. Among the design parameters, lifting capacity, lifting height, lifting speed, and traveling speed are used for the design of the lifting and traveling mechanisms, while the span is used for the design of the chassis.

[0004] After years of development in the crane industry and the continuous accumulation and improvement of design data, the hoisting mechanism and traveling mechanism have basically completed standardized design. However, the chassis has not yet achieved standardized design, due to the following technical factors:

[0005] First, the frame span is determined by the track spacing of the user's factory in each project. However, the design institutes for each project are different, and the span design varies greatly with almost no pattern to follow, which makes the frame design process inefficient.

[0006] Secondly, the design of load-bearing beams in the frame, especially box beams, requires consideration not only of the beam's cross-sectional size but also of the placement of internal stiffeners. These stiffeners need to be placed corresponding to various components in the mechanism to provide local reinforcement. However, purchased components such as motors and brakes vary greatly in size due to differences in brand or model, making it impossible to determine their position relative to the centerline of the mechanism. Consequently, the position of the stiffeners in the lower box beams also cannot be determined, making the standardized and modular design of the frame quite challenging. Summary of the Invention

[0007] To address some or all of the technical problems existing in the prior art, this invention provides a standardized design structure and method for a large-tonnage parametric customized crane frame, which is low in design difficulty, highly efficient, and capable of standardized customized design.

[0008] The technical solution of the present invention is as follows:

[0009] In a first aspect, the present invention provides a standardized design structure for a large-tonnage parametric customized crane frame, wherein the frame is a segmented structure, comprising:

[0010] A standard frame, which cooperates with the lifting and running mechanisms of the crane trolley;

[0011] A first adjustment frame is detachably connected to one side of the standard frame;

[0012] The second adjustment frame is detachably connected to the other side of the standard frame;

[0013] A bracket is provided on the outer top surface of the standard frame to support and fix components such as the motor, brake and reducer of the crane trolley, so that the output shaft axes of the components such as the motor, brake and reducer located on the upper part of the standard frame are in the same plane. Several reinforcing ribs are provided inside the standard frame, and reinforcing ribs are correspondingly provided below the motor, the brake and the reducer.

[0014] Furthermore, the standard frame, the first adjustment frame, and the first adjustment frame are all connected by high-strength bolts.

[0015] Furthermore, the standard frame, the first adjustment frame, and the second adjustment frame form a single plane on their top surfaces after being interconnected.

[0016] Furthermore, the reinforcing ribs are evenly distributed within the standard frame according to a preset pattern.

[0017] Furthermore, the reinforcing rib includes a first reinforcing rib and a second reinforcing rib. The first reinforcing rib is disposed through the interior of the standard frame and is fixedly connected to the upper and lower bottom surfaces of the standard frame. One end of the second reinforcing rib is fixedly connected to the upper bottom surface inside the standard frame, and the other end is a free end.

[0018] Secondly, the present invention also provides a standardized design method for a large-tonnage parametric customized crane trolley frame, comprising:

[0019] Determine the frame dimensions based on the dimensions of the crane trolley;

[0020] Design a segmented standard frame based on the determined frame dimensions, including the dimensions of the first and second adjustment frames;

[0021] Several reinforcing ribs are provided inside the standard frame, and several brackets are fixedly installed on the top of the standard frame to complete the standardized design of the car frame.

[0022] The main advantages of the technical solution of this invention are as follows:

[0023] The present invention discloses a standardized design structure for a large-tonnage parametric customized crane frame, comprising a standard frame, a first adjusting frame, and a second adjusting frame. The standard frame is set to a fixed length, while the first and second adjusting frames are designed to adjust their dimensions according to design requirements. The design is changed from an integrated design to a split design, divided into three sections, so that the intermediate standard frame, which cooperates with the standardized hoisting and running mechanisms, can become a standard universal module. Meanwhile, in the areas where purchased components such as motors and brakes are located on the frame, multiple equally spaced stiffening plates are set in the corresponding box beams as reinforcing ribs. The positions of the seats for purchased components such as motors and brakes are determined based on the positions of these stiffening plates. This solves the problem that the positions of the stiffening plates in the box beams cannot be determined due to differences in the brand, model, and size of purchased components such as motors and brakes. At the same time, through the three-section frame design, the middle section of the frame (standard frame), which accounts for the largest proportion, can be designed as a universal standard module. By arranging multiple equally spaced stiffening ribs in the beams in advance, and determining the irregularly shaped brackets (seats) based on the positions of the stiffening ribs, the middle section of the frame is designed as a standard frame when designing the overall frame. Only the adjustment frames at both ends and the brackets for purchased components on the middle standard frame need to be designed according to the overall length. Thus, the middle section of the frame is ultimately designed as a universal standard module, achieving standardized frame design with low design difficulty and high efficiency.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0034] It should be noted that the parametric customization design in this invention refers to the design of each crane trolley according to the user's requirements for lifting capacity, lifting height, lifting speed, running speed, span (trolley track spacing), etc., rather than designing a series of crane trolleys of various different specifications for the user to choose from.

[0035] The technical solutions provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] As attached Figures 1-6 As shown, this embodiment of the invention provides a standardized design structure for a large-tonnage parametric customized crane trolley frame 3, which includes:

[0038] Standard frame 31, which cooperates with the lifting mechanism 1 and the running mechanism 2 of the crane trolley;

[0039] The first adjustment frame 32 is detachably connected to one side of the standard frame 31;

[0040] The second adjustment frame 33 is detachably connected to the other side of the standard frame 31;

[0041] With this setting, such as Figure 1 and Figure 2 As shown, the standard frame 31 is of fixed size, while the first adjusting frame 32 and the second adjusting frame 33 are of adjustable size. The size of the standard frame 31 is determined based on the length of the minimum crane frame 3 or according to the customized requirements, based on the overall length. The length of the standard frame 31 is not greater than the length of the frame 3. The overall size of the frame 3 is designed according to the requirements. The first adjusting frame 32 and the second adjusting frame 33 located on both sides of the standard frame 31 are designed and determined according to the overall size of the frame 3.

[0042] A bracket 13 is provided on the outer top surface of the standard frame 31 to support and fix components such as the crane trolley motor, drum 4, brake 6 and reducer 7, so that the output shaft axes of the components such as the motor drum 4, brake 6 and reducer 7 located on the upper part of the standard frame 31 are in the same plane, and several reinforcing ribs are provided inside the standard frame 31.

[0043] It should be noted that reinforcing ribs are provided inside the standard frame 31, and the locations of the reinforcing ribs are marked so that the location of the reinforcing ribs inside the standard frame 31 can be known from the outside of the standard frame 31. The motor, brake 6 and reducer 7 are installed at the location of the reinforcing ribs, so that the motor, brake 6 and reducer 7 are located directly above the reinforcing ribs. This not only provides support, but also reduces the vibration of the motor, brake 6 and reducer 7 during operation, making the operation more stable.

[0044] Specifically, the standard frame 31, the first adjusting frame 32, and the second adjusting frame 33 are all connected by high-strength bolts 12. The top surfaces of the standard frame 31, the first adjusting frame 32, and the second adjusting frame 33 after being connected to each other form the same plane.

[0045] With this configuration, the first adjustment frame 32 and the second adjustment frame 33 are connected to both sides of the standard frame 31 by high-strength bolts 12, which makes the first adjustment frame 32 easy to connect while ensuring the strength of the connection.

[0046] In some optional implementations of this embodiment, the frame 3 includes an I-beam, a box beam, and a platform. The I-beam and box beam are positioned below the main components of the mechanism to provide load-bearing support. The platform facilitates access and maintenance. Reinforcing ribs are provided in the brackets 13 (bases) of the I-beam and box beam corresponding to each component to provide local reinforcement. The shape of each bracket 13 (base) is preferably a regular symmetrical shape. Each bracket 13 (base) includes a cover plate 131 and stiffening plates 132. After the bracket 13 (base) is designed according to the dimensions of the base of purchased components such as the motor 5, the stiffening plates 132 of the bracket 13 (base) are then set at the positions of the first reinforcing rib 14 and / or the second reinforcing rib 15 inside the I-beam and box beam. Specifically, the structure of the bracket is as follows: Figure 3 , Figure 4 and Figure 5 As shown.

[0047] It should be noted that, as Figure 1 , Figure 2 and Figure 6 As shown, the lifting mechanism 1 includes a reducer, a drum 4, a motor 5, and a brake 6. For ease of transport, maintenance, and replacement, each component of the lifting mechanism 1 is bolted to the standard frame 31 of the chassis 3. Below the drum 4, motor 5, brake 6, and reducer 7, respectively, are corresponding support and connection points: a drum seat 8, a motor seat 9, a brake seat 10, and a reducer seat 11. Since the center heights of each component are different, brackets 13 (bases) of different heights are required for each component. Connection holes are machined on the upper surface of the brackets 13 (bases). The bases are welded to the chassis 3 according to the designed positions and then bolted to the components. This arrangement, on the one hand, allows for the fixing and connection of the motor 5, reducer, drum 4, and other structures through the brackets 13 (bases); on the other hand, it ensures that the center lines of the motor 5, reducer, and drum 4 are located in the same plane, guaranteeing operational stability, safety, and reliability.

[0048] As one of the optional implementations of this embodiment, the crane's running mechanism 2 is also connected to the frame 3 in the same way.

[0049] In some optional implementations of this embodiment, the reinforcing ribs are evenly distributed within the standard frame 31 according to a preset pattern.

[0050] Specifically, such as Figure 6 As shown, the reinforcing ribs include a first reinforcing rib 14 and a first reinforcing rib 15. The first reinforcing rib 14 is disposed through the interior of the standard frame 31 and is fixedly connected to the upper and lower bottom surfaces of the standard frame 31. One end of the first reinforcing rib 15 is fixedly connected to the upper bottom surface inside the standard frame 31, and the other end is a free end.

[0051] In some optional implementations of this embodiment, the above-mentioned regular distribution method is as follows: the first reinforcing rib 14 divides the several second reinforcing ribs into several units, and the second reinforcing ribs 15 are evenly distributed in each unit. The number of first reinforcing ribs 14 and second reinforcing ribs 15 contained in each unit is the same or different, and the distance between each unit is the same or different.

[0052] It should be noted that the first reinforcing rib 14 and the second reinforcing rib 15 described above are only one achievable exemplary method and are not the only limitation on the standardized design of the crane frame of the present invention. The first reinforcing rib 14 and the second reinforcing rib 15 can also be set in a way that is equally spaced and staggered.

[0053] In some optional implementations of this embodiment, the lower part of the main load-bearing components of equipment such as speed reducers that bear heavy weight is provided with long reinforcing ribs, such as the first reinforcing rib 14; the lower part of the relatively light load-bearing components such as motors 5 and brakes 6 is provided with short reinforcing ribs, such as the second reinforcing rib 15.

[0054] With this configuration, compared to the first reinforcing rib 14 and / or second reinforcing rib 15 in the beam corresponding to the support 13 (base), the ribs will no longer be set according to the position of the support 13 (base). Instead, multiple equally spaced first reinforcing ribs 14 and / or second reinforcing ribs 15 will be arranged in advance in the I-beam and box beam. The stiffening plates in the support 13 (base) will be set according to the position of the nearest first reinforcing rib 14 and / or second reinforcing rib 15. The shape of the support 13 (base) may be irregular, which solves the problem of uncertain or unchangeable position of the first reinforcing rib 14 and / or second reinforcing rib 15 in the closed box beam.

[0055] In some optional implementations of this embodiment, after the first reinforcing rib 14 and the second reinforcing rib 15 are welded inside the beam of the intermediate standard frame 31, lines are drawn at corresponding positions outside the beam (the length of the line can represent the length of the reinforcing rib, such as a shorter line length for a shorter first reinforcing rib 14, and a longer line length for a longer second reinforcing rib 15, etc.). When setting the bracket 13 (base), the shape of the bracket 13 (base) is determined according to the position and length of the drawn lines. Specifically, the position of the stiffening plate 132 of the bracket 13 (base) is determined according to the position of the first reinforcing rib 14 and the second reinforcing rib 15 inside the beam, and the overall structure of the bracket 13 (base) is determined according to the overall structure of the frame itself.

[0056] In summary, the standardized design structure of the trolley frame 3 for a large-tonnage parametric customized crane of the present invention is achieved by setting the frame 3 as a segmented structure (split structure), divided into three sections, with each pair of sections connected by high-strength bolts 12. Among the three sections of the frame 3, the middle standard frame 31, which cooperates with the hoisting mechanism 1 and the running mechanism 2, accounts for the largest proportion of the frame 3. The hoisting mechanism 1 and the running mechanism 2 have been standardized, and their overall dimensions are determined. Only the dimensions of purchased components such as the motor and brake 6 are uncertain. Therefore, this section has the conditions to be designed as a standard universal module. When designing for each project, the lengths of the first adjusting frame 32 and the second adjusting frame 33 on both sides are modified according to the actual span of the project, making these two sections non-standard modules to meet project requirements. This allows the frame 3 to be unaffected by the track spacing in the user's factory or the dimensions of purchased components in the mechanism, achieving a standardized universal module design for the frame 3.

[0057] Therefore, the standardized design structure of the trolley frame 3 of a large-tonnage parametric customized crane of the present invention solves the problem that the position of the inner stiffening plate 132 of the box beam cannot be determined due to the different brands or models of purchased parts such as motor 5 and brake 6 in the existing mechanism; and through the three-section frame 3 design, the middle part of the frame 3, which accounts for the largest proportion, can be designed as a general standard module. Furthermore, by arranging several first stiffening ribs 14 and / or second stiffening ribs 15 in advance in the beam, and determining the irregularly shaped bracket 13 (seat) according to the position of the several first stiffening ribs 14 and / or second stiffening ribs 15 designed in the beam, the middle part of the frame is made into a standard frame when designing the overall frame. Only the adjustment frames at both ends need to be designed according to the overall length. Thus, the middle part of the frame 3 (standard frame 31) is finally designed as a general standard module, and the frame 3 completes the standardized design.

[0058] It should also be noted that the trolley frame 3 of the present invention includes, but is not limited to, the trolley frame 3 of a crane, and can also be applied to the trolley frame 3 of all other equipment with longer dimensions, and can also be applied to all structures with longer lengths, including but not limited to the frame 3.

[0059] Example 2

[0060] This invention also provides a standardized design method for a large-tonnage parametric customized crane trolley frame 3, including:

[0061] Based on the dimensions of the crane trolley, determine the dimensions of the frame 3; based on the determined dimensions of the frame 3, design the dimensions of the segmented standard frame 31, the first adjusting frame 32, and the second adjusting frame 33; set several reinforcing ribs inside the standard frame 31, and fix several brackets 13 on the top of the standard frame 31 to complete the standardized design of the trolley frame 3.

[0062] The car frame 3 designed by the method of this invention has low design difficulty and high efficiency, and has the conditions to become a standard universal module. It solves the problem that the position of the inner stiffening plate 132 of the box beam cannot be determined due to the different brands or models of purchased parts such as motor 5 and brake 6 in the existing mechanism. At the same time, through the three-section frame design, the middle part of the frame 3, which accounts for the largest proportion, has the conditions to be designed as a universal standard module. Furthermore, by arranging multiple equally spaced short stiffening plates 132 and irregularly shaped brackets 13 (seats) in advance in the beam, the middle part of the frame (standard frame 31) is finally designed as a universal standard module, so that the frame 3 completes the standardized design.
