Description

Technical Field

[0001] The present application relates to the technical field of gearbox installation, and in particular to a suspension rod. Background Art

[0002] Gearbox is an important component of many mechanical equipment. In rail vehicles, especially high-speed trains, traction motors are generally used to drive bogies through gearboxes. Usually one end of the gearbox is supported on the axle, and the other end is connected to the bogie through a hanger device. The hanger mainly plays the role of supporting the gearbox.

[0003] Existing hangers mostly use rigid connection methods, which are mainly used to support heavy gearboxes and fix them on the bogies. However, the hangers not only need to bear the weight of the gearbox itself and the dynamic loads generated by train starting, braking and traction motor short circuit, but also should be able to absorb the relative displacement between the gearbox and the bogie in all directions.

[0004] Regarding the above-mentioned related technologies, the commonly used rigid connection methods, such as bolt connection, welding fixation and snap connection, can ensure the stability and safety of the gearbox to a certain extent. However, in some special cases, such as the bumpy state of a car driving or the high-frequency vibration of industrial equipment, the rigid connection is prone to fatigue damage or even breakage, seriously affecting the service life of the boom. In addition, due to the compact installation space of the gearbox, the traditional fastener operation is complicated and time-consuming, which increases the difficulty of maintenance. Summary of the invention

[0005] In order to increase the service life of a suspension rod, the present application provides a suspension rod.

[0006] The present application provides a suspension rod, which adopts the following technical solution: A suspension rod, comprising: A gear box, wherein a mounting hole is provided on the gear box; A hoisting assembly, the hoisting assembly is installed on the gear box, and the hoisting assembly is used to support and suspend the gear box; A quick-install assembly, the quick-install assembly is installed on the hoisting assembly, and the quick-install assembly is used to quickly install the gearbox on the bogie; A buffer component is installed on the quick-release assembly, and is used to absorb and buffer vibrations generated during the operation of the gear box.

[0007] By adopting the above technical solution, the lifting assembly can effectively support and suspend the gearbox. At the same time, the quick-release assembly enables the gearbox to have a quick installation function, thereby improving the installation efficiency. The buffer can significantly reduce the vibration transmission during the operation of the gearbox, extend the service life of related components, and improve the service life of the lifting parts.

[0008] Optionally, the hoisting assembly includes: A first ball joint, the first ball joint comprising a first ball head seat, a first ball head and a rod end, the first ball head seat being fixedly mounted in the mounting hole, the first ball head being arranged in the first ball head seat, and the rod end being fixedly mounted on the first ball head; A rod body, one end of which is fixedly mounted on the rod end, and the other end of which is provided with a connecting hole; a second ball joint, the second ball joint comprising a second ball head seat and a second ball head, the second ball head seat being fixedly installed in the connecting hole, and the second ball head being arranged in the second ball head seat; An elastic member, wherein the elastic member is mounted on the first ball joint and the second ball joint, and the elastic member is used to realize relative movement between the lifting components.

[0009] By adopting the above technical solution, the first ball joint and the second ball joint enable the lifting assembly to achieve small-range movement in multiple directions, avoiding the rigid connection between the boom and the gearbox and the bogie, improving the adaptability of the boom to different working conditions, and effectively alleviating the problem of slight displacement of the gearbox during operation. The elastic parts further enhance the vibration reduction effect, reduce mechanical damage caused by vibration, and extend the service life of the boom and related components.

[0010] Optionally, the elastic member is a rubber sleeve, and two rubber sleeves are provided, one of which is fixedly installed between the first ball head seat and the first ball head, and the other of which is fixedly installed between the second ball head seat and the second ball head.

[0011] By adopting the above technical solution, the two rubber sleeves are respectively fixedly installed between the first ball head seat and the first ball head and between the second ball head seat and the second ball head, which can effectively absorb and buffer the vibration generated during the operation of the gear box and reduce the force of the vibration transmitted to other components, thereby improving the stability and reliability of the entire system. At the same time, the rubber sleeve also has good wear resistance and corrosion resistance, which extends the service life of the boom.

[0012] Optionally, there are two groups of quick-release components, both of which are installed on the second ball head and symmetrically arranged on both sides of the second ball head, and the quick-release components include: A mounting box, the mounting box being fixedly mounted on the second ball head; A sliding block, wherein the sliding block is slidably mounted on the mounting box, and a sliding direction is along an axis direction of the second ball head; A telescopic rod, wherein the telescopic rod is arranged in the installation box, one end of the telescopic rod is fixedly mounted on the installation box, and the other end of the telescopic rod is fixedly mounted on the sliding block; A first spring, wherein the first spring is wound around the telescopic rod, and two ends of the first spring are respectively fixedly connected to the installation box and the sliding block.

[0013] By adopting the above technical solution, two sets of quick-release components are symmetrically installed on both sides of the second ball head, which can achieve fast and accurate positioning, greatly improving the installation efficiency of the gearbox and the bogie. Its symmetrical structure makes the overall force more uniform and ensures the stability of the connection. During installation, the sliding block slides along the axis of the second ball head, and the telescopic rod cooperates with the first spring, which can not only buffer the external force impact during the installation process, but also adapt to the position deviation between the bogie and the gearbox. Even under complex working conditions, it can ensure the smooth completion of the installation, improving the practicality and reliability of the entire boom system.

[0014] Optionally, a mounting slot is provided in the mounting box, a sliding slot is provided on the sliding block, and the quick-install assembly further comprises: A card block, which is slidably mounted in the slide groove, and the sliding direction is perpendicular to the sliding direction of the sliding block, and the card block is provided with a guiding inclined surface; A second spring, wherein the second spring is arranged in the slide groove, and two ends of the second spring are respectively fixedly connected to the clamping block and the sliding block; A rack, the rack is slidably arranged in the mounting groove, and the sliding direction is consistent with the sliding direction of the sliding block, and a clamping groove is provided on a side of the rack close to the sliding block, and the clamping groove is adapted to the clamping block; A gear, the gear being rotatably mounted in the mounting groove, the gear being meshed with the rack; A connecting column is coaxially arranged on the gear, the connecting column is key-connected to the gear, and one end of the connecting column passes through the installation box and is threadedly connected to the installation box.

[0015] By adopting the above technical solution, during installation, it is only necessary to make the card block enter the rack card slot under the action of the second spring when the sliding block slides, so that the rack moves, and the connecting column is driven to rotate through the gear rack transmission to achieve rapid fixation. When disassembling, it is only necessary to slide the rack in the opposite direction. The operation is simple and the installation and disassembly efficiency is improved. The structure is compact, and the various components are reasonably arranged in the installation box and the sliding block. When space is limited, it can effectively utilize the space to meet the installation requirements of the equipment.

[0016] Optionally, the buffer member includes: A slide plate, wherein the slide plate is arranged below the installation box, the connecting column is passed through the slide plate, and the connecting column is slidably connected to the slide plate; A damper, wherein a plurality of dampers are provided, one end of the damper is fixedly mounted on the mounting box, and the other end of the damper is fixedly mounted on the slide plate; A third spring is wound around the damper, and two ends of the third spring are fixedly connected to the slide plate and the installation box respectively.

[0017] By adopting the above technical solution, the damper and the third spring between the slide plate and the mounting box work together to effectively absorb and buffer the vibration generated during the operation of the gear box, reduce the impact force transmitted to the bogie or other related components, and thus extend the service life of the boom and related components.

[0019] By adopting the above technical solution, the opening of the disassembly hole makes it unnecessary to completely remove the installation box when the internal parts of the quick-release assembly need to be replaced or repaired. It is only necessary to move the rack in the opposite direction through the disassembly hole so that the connecting column can be retracted into the installation box, which greatly simplifies the maintenance process and improves work efficiency.

[0020] Optionally, the surface of the rod body is coated with an anti-corrosion coating.

[0021] By adopting the above-mentioned technical solution, the surface of the rod body is coated with an anti-corrosion coating, which can effectively improve the corrosion resistance of the rod body and extend the overall service life of the boom. At the same time, when used in a humid or corrosive environment, the anti-corrosion coating can reduce the impact of the external environment on the rod body material and ensure the stability and reliability of the boom structure.

[0022] Optionally, the axis of the connecting hole is perpendicular to the axis of the mounting hole.

[0023] By adopting the above technical solution, stress can be effectively dispersed, concentrated force can be avoided, and structural strength and stability can be improved. Secondly, during the installation process, it provides operators with a more flexible operating space, which is convenient for applying force in complex environments, especially in narrow spaces. It can achieve rapid installation and disassembly, making the overall structure more compact and reducing the occupation of surrounding space. At the same time, the cross-shaped hole arrangement can also enhance the torsional resistance of the components to a certain extent, ensuring the stable operation of the equipment.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The setting of quick-install components enables the gearbox to be quickly installed on the bogie, which simplifies the installation process, reduces the operation time and maintenance difficulty, and is especially suitable for occasions with narrow space; 2.

[0033] When using the boom, first install the hoisting assembly 2 at the mounting hole of the gear box 1, then use the quick-install assembly 3 to quickly install the gear box 1 on the bogie to achieve rapid assembly. During the operation of the gear box 1, the buffer 4 installed on the quick-install assembly 3 begins to play a role, continuously absorbing and buffering the vibration generated by the operation of the gear box 1, ensuring the smooth operation of the entire system and increasing the service life of the boom.

[0034] Reference Figure 2The hoisting assembly 2 includes a first ball joint 21, a rod body 22, a second ball joint 23 and an elastic member 24. The first ball joint 21 includes a first ball head seat 211, a first ball head 212 and a rod end 213. The first ball head seat 211 is cylindrical, and the central opening is adapted to the first ball head 212. The first ball head seat 211 is fixedly installed in the mounting hole, and the first ball head seat 211 and the gear box 1 are in interference connection.

[0035] Reference Figure 2 and Figure 3 The first ball head 212 is arranged in the first ball head seat 211, and two rod ends 213 are arranged. The two rod ends 213 are symmetrically arranged and fixedly installed on both sides of the first ball head 212. The rod body 22 is an inverted Y-shaped structure. The bottom end of the rod body 22, that is, both sides of the Y-shaped bifurcation are fixedly installed on the two rod ends 213 by screws. A connecting hole is opened at the top of the rod body 22, and the axis of the connecting hole is perpendicular to the axis of the mounting hole.

[0036] Reference Figure 4 The second ball joint 23 includes a second ball head seat 231 and a second ball head 232. The second ball head seat 231 is fixedly installed in the connecting hole. The second ball head seat 231 and the gear box 1 are interference connected. The second ball head 232 is arranged in the second ball head seat 231. The second ball head seat 231 is cylindrical, and the center opening is adapted to the second ball head 232. The elastic member 24 is installed on the first ball joint 21 and the second ball joint 23. The elastic member 24 is used to realize the relative movement between the lifting components 2.

[0037] Reference Figure 4 The elastic member 24 is a rubber sleeve 241 , and two rubber sleeves 241 are provided. One rubber sleeve 241 is fixedly installed between the first ball head seat 211 and the first ball head 212 , and the other rubber sleeve 241 is fixedly installed between the second ball head seat 231 and the second ball head 232 .

[0038] When the gearbox 1 is installed on the bogie, the first ball joint 21 is installed in the mounting hole, one end of the rod body 22 is fixedly installed on the first ball joint 21, and then the second ball joint 23 is installed in the connecting hole at the other end of the rod body 22, and connected to the bogie through the second ball joint 23, the gearbox 1 is fixed, and the rubber sleeve 241 is arranged on the first ball joint 21 and the second ball joint 23, so that after the installation is completed, the first ball head seat 211 and the first ball head 212 and the second ball head seat 231 and the second ball head 232 can be slightly displaced, providing a certain buffer and flexibility for the hoisting of the entire gearbox 1, ensuring that the gearbox 1 can adapt to different motion states and stress conditions. At the same time, the axis of the connecting hole and the axis of the mounting hole are perpendicular to each other, forming a cross hoisting, which has a compact structure and saves installation space.

[0039] Reference Figure 4 and Figure 5There are two groups of quick-release components 3, both of which are installed on the second ball head 232 and are symmetrically arranged on both sides of the second ball head 232. The quick-release components 3 include an installation box 31, a sliding block 32, a telescopic rod 33, a first spring 34, a clamping block 35, a second spring 36, a rack 37, a gear 38 and a connecting column 39.

[0040] Reference Figure 4 and Figure 5 The mounting box 31 is a rectangular box-shaped structure with an opening on one side, and the open side is away from the second ball head 232. The mounting box 31 is fixedly mounted on the second ball head 232, and the sliding block 32 is slidably mounted on the mounting box 31, and the sliding direction is along the axial direction of the second ball head 232. A guiding inclined surface is provided on the sliding block 32, and the guiding inclined surface makes it easy for the rod body 22 to be inserted into the bogie. The telescopic rod 33 is arranged in the mounting box 31, and one end of the telescopic rod 33 is fixedly mounted on the mounting box 31, and the other end of the telescopic rod 33 is fixedly mounted on the sliding block 32. The first spring 34 is wound around the telescopic rod 33, and the two ends of the first spring 34 are respectively fixedly connected to the mounting box 31 and the sliding block 32.

[0041] Reference Figure 4 and Figure 5 A mounting groove is provided in the mounting box 31, a sliding groove is provided at the bottom of the sliding block 32, the card block 35 is slidably installed in the sliding groove, and the sliding direction is perpendicular to the sliding direction of the sliding block 32, and a guiding inclined surface is provided on the card block 35, a second spring 36 is arranged in the sliding groove and is vertically arranged, and the two ends of the second spring 36 are respectively fixedly connected to the card block 35 and the sliding block 32, and the rack 37 is slidably arranged in the mounting groove, and the sliding direction is consistent with the sliding direction of the sliding block 32, and a card groove is provided on the side of the rack 37 close to the sliding block 32, and the card groove is adapted to the card block 35, and the gear 38 is rotatably installed in the mounting groove, and the gear 38 is meshed with the rack 37, and the connecting column 39 is vertically arranged, and one end of the connecting column 39 is coaxially penetrated on the gear 38, and the connecting column 39 is key-connected with the gear 38, and the other end of the connecting column 39 penetrates the mounting box 31, and the connecting column 39 is threadedly connected to the mounting box 31.

[0042] During installation, push the rod body 22 into the installation position of the bogie, at which time the sliding blocks 32 on both sides are retracted into the installation box 31, the telescopic rod 33 is retracted, and the first spring 34 is in a compressed state. As the sliding blocks 32 continue to retract, the slide slot is connected to the card slot, and under the action of the second spring 36, the card block 35 slides outward and enters the card slot. As the rod body 22 reaches the installation position, the sliding blocks 32 on both sides are released, and under the action of the first spring 34, they slide toward the side of the transport installation box 31, while driving the rack 37 clamped with the card block 35 to slide, so that the gear 38 rotates, and then drives the connecting column 39 to rotate, and the end of the connection away from the gear 38 slides downward and penetrates into the fixing hole of the gear box 1 of the bogie, so as to realize the quick connection between the gear box 1 and the bogie. In the scenario of limited space, when installation tools such as wrenches cannot enter the installation position of the rod body 22, the installation can be completed by the quick-install assembly 3 without the need to use bolts separately.

[0043] Reference Figure 6 and Figure 7 , there are two groups of buffers 4, the number of which corresponds to the number of quick-install components 3, and the buffers 4 include a slide plate 41, a damper 42, and a third spring 43. The slide plate 41 is a rectangular plate structure, and the slide plate 41 is arranged below the installation box 31. The connecting column 39 is passed through the slide plate 41, and the connecting column 39 is slidably connected to the slide plate 41. There are two dampers 42, one end of the damper 42 is fixedly mounted on the installation box 31, and the other end of the damper 42 is fixedly mounted on the slide plate 41. The third spring 43 is wound on the damper 42, and the two ends of the third spring 43 are fixedly connected to the slide plate 41 and the installation box 31 respectively.

[0044] When the gearbox 1 is running and generates vibration, the vibration will be transmitted to the buffer 4 through the installation box 31 of the quick-release assembly 3. At this time, the damper 42 plays a key role. The two dampers 42 will generate a damping force on the movement of the installation box 31 relative to the slide plate 41, thereby suppressing the rapid transmission and amplification of the vibration. The third spring 43 wound around the damper 42 will also undergo elastic deformation. Under the action of the elastic force of the spring, the vibration is further buffered, and the energy of the vibration is converted into the elastic potential energy of the spring, thereby reducing the influence of the vibration on the suspension rod.

[0045] Reference Figure 3 A disassembly hole 311 is opened on the installation box 31 , and the opening direction of the disassembly hole 311 is consistent with the sliding direction of the rack 37 , and the position of the disassembly hole 311 is colinear with the sliding direction of the rack 37 .

[0046] When the gearbox 1 needs to be disassembled from the bogie, the rack 37 is pushed through the disassembly hole 311 to move the rack 37 toward the second ball head 232. The sliding of the rack 37 drives the gear 38 to rotate in the opposite direction, thereby causing the connecting column 39 to move upward and be removed from the fixing hole in the bogie for disassembly.

[0047] The surface of the rod body 22 is coated with an anti-corrosion coating, which can maintain the original strength and structural integrity of the rod body 22, ensuring that the hoisting assembly 2 always maintains a reliable load-bearing capacity during the process of supporting the suspended gearbox 1, avoiding structural failure caused by corrosion of the rod body 22, and ensuring safe operation of the equipment.

[0048] The implementation principle of a suspension rod in an embodiment of the present application is as follows: when the gear box 1 is installed through the suspension rod, the first ball joint 21 is interference fit with the mounting hole of the gear box 1, and the suspension rod is directly connected to the gear box 1. The rod body 22 is in an inverted Y shape, and the first and second ball joints are respectively connected at both ends to form a cross suspension structure, which is compact and space-saving. The rubber sleeve 241 allows slight displacement between the ball joints to achieve a non-rigid connection, thereby providing buffering and flexibility for the lifting of the gear box 1, reducing vibration impact, and increasing the life of the suspension rod.

[0049] During installation, the rod body 22 is pushed to the bogie installation position through the quick-release assembly 3, the sliding block 32 is retracted, and the clamping block 35 slides into the rack 37 slot under the action of the second spring 36. After the rod body 22 is in place, the sliding block 32 slides under the action of the first spring 34, driving the rack 37 to rotate the gear 38, and the connecting column 39 is rotated to penetrate the bogie fixing hole to achieve quick connection. When space is limited and tools such as wrenches cannot be used, it can also be easily installed.

[0050] The number of buffers 4 corresponds to that of quick-release components 3. When the gearbox 1 vibrates during operation, the damper 42 generates a damping force to suppress the transmission of vibration, and the third spring 43 elastically deforms to buffer the vibration, thereby reducing the impact on the boom. In addition, the rod body 22 is coated with an anti-corrosion coating to maintain strength and structural integrity, thereby ensuring safe operation of the equipment.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
