[0034] Through the above accompanying drawings, the clear embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These accompanying drawings and the written description are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0036] As described in the background art, for electric locomotives, such as HXD3D type electric locomotives, after actually running 80 - 100 million kilometers, advanced repairs (referred to as C4 or C5 repairs in the industry) are required. According to the technical requirements of the repair process, the bearings of the driving gear of the traction motor need to be replaced.

[0037] In the related art, when replacing the bearings of the driving gear of the traction motor, it is necessary to disassemble and remove the wheel set of the locomotive drive device, the traction motor, the axle box bearing, and the axle of the wheel set in sequence. After removing the above components, the disassembly and removal of the bearings of the driving gear of the gearbox can be carried out. After removing and replacing and maintaining the bearings of the driving gear, the wheel pressing operation is carried out, and the wheel reverse pressing experiment is carried out 24 hours later to ensure the pressing quality. After reassembling the axle box bearing and the traction motor, the operation of replacing the bearings of the driving gear is completed.

[0038] According to the above process, due to the need to disassemble relevant components, as well as carry out pressing operations and reverse pressing tests, a large amount of labor and equipment costs need to be increased. The entire operation process requires at least three working days to complete the replacement of the main gear bearings. The operation cycle is long and the efficiency is low. Moreover, during the disassembly and assembly of the axle box bearing and the removal and pressing of the wheel and the axle, there may be damage to large components caused by axle strain or changes in the interference fit amount, resulting in economic losses.

[0039] Based on the above related descriptions, in one or more embodiments of the present application, an auxiliary disassembly and assembly tooling for a locomotive gearbox is provided. Since the wheel set and the gearbox are flexibly connected, when the axle box is placed on the support seat, the adjusting component drives the support seat to displace along the side away from the gearbox, so that a certain angle is formed between the wheel set and the gearbox. This angle is also the assembly gap formed between the wheel set and the gearbox. This assembly gap can reserve the working space for operators to replace parts, and there is no need to remove the axle box bearing and the wheel set. The bearings of the driving gear of the gearbox can be directly replaced, thus simplifying the operation process and improving work efficiency.

[0040] In addition, since the staff can directly disassemble and assemble the bearings of the driving gear in the gearbox from the assembly gap, without removing the axle box bearing and the wheel set, the quality problems caused by other processes during the replacement of the bearings of the driving gear can be avoided, thus saving the maintenance cost.

[0041] The following describes the auxiliary disassembly and assembly tooling for the locomotive gearbox in conjunction with the accompanying drawings.

[0042] As Figure 1 and Figure 2 shown, the auxiliary disassembly and assembly tooling for the locomotive gearbox in the embodiment of the present application includes a support platform 100, a support seat 200, and an adjustment component 300.

[0043] Among them, the support seat 200 is arranged on the support platform 100 and is slidably connected to the support platform 100. The support seat 200 is used to support the axle box 400; the adjustment component 300 is connected to the support seat 200 to drive the displacement of the support seat 200; when the axle box 400 is placed on the support seat 200, the adjustment component 300 drives the support seat 200 to displace along the side away from the gearbox 500, so as to form an assembly gap between the wheel set 600 and the gearbox 500.

[0044] By driving the support seat 200 to displace along the side away from the gearbox 500 through the adjustment component 300, it is possible to effectively create the necessary space for replacing the bearing of the driving gear, without completely disassembling the wheel set 600 or the gearbox 500, thus greatly shortening the maintenance time and improving the work efficiency. At the same time, since the support seat 200 only moves the axle box 400, it avoids unnecessary movement of other components when replacing the bearing, reduces the possibility of damage to other components caused by improper operation, and extends the service life of the equipment.

[0045] It should be noted that in the embodiment of the present application, for example, taking the disassembly of the bearing of the driving gear of the HXD3D type electric locomotive as an example for description, the HXD3D type electric locomotive is a type of AC drive main line quasi-high-speed passenger electric locomotive used for railways. Of course, it can also be applied to other types of electric locomotives.

[0046] Generally, an electric locomotive includes an axle box 400, a gearbox 500, and a wheel set 600. The axle box 400 is connected to the wheel set 600, and the wheel set 600 is connected to the gearbox 500. The traction motor of the electric locomotive is connected to the wheel set 600 through the gearbox 500. In the HXD3D type electric locomotive, a hollow shaft is also designed to transmit power, and the traction motor is directly or indirectly connected to the wheel set 600 through the hollow shaft. This method helps to reduce weight and simplify maintenance work.

[0047] In some embodiments, a rubber joint is provided between the output shaft of the gearbox 500 and the wheel pair shaft, and the rubber joint is used to form the flexible connection effect between the gearbox 500 and the wheel set 600. Therefore, when the axle box 400 is driven to shift by an external force, the wheel set 600 synchronously displaces, and an assembly gap will be formed between the gearbox 500 and the wheel set 600 due to the flexible connection.

[0048] Of course, an electric locomotive should also have other related installation components for normal driving, such as couplings, bogie components, etc., which will not be elaborated in the embodiments of the present application.

[0049] As Figure 3 shown, in some embodiments, a lubricating member 106 is provided on the support platform 100, and the lubricating member 106 is used to contact the support seat 200.

[0050] Exemplarily, along the displacement direction of the support seat 200, a plurality of installation grooves 105 are spaced apart on the support platform 100, and the lubricating member 106 is a roller disposed in the installation groove 105.

[0051] Of course, the lubricating member 106 can be other components in addition to the above-mentioned roller disposed in the installation groove 105. For example, lubricating oil or grease can be coated on the support platform 100, or balls or bearings can be laid on the support seat 200, as long as it can facilitate the relative sliding between the support seat 200 and the support platform 100.

[0052] When the support seat 200 is placed on the support platform 100, the bottom of the support seat 200 contacts the roller, which can reduce the friction and resistance during the displacement of the support seat 200, facilitate the displacement of the support seat 200, and thus reduce the labor intensity.

[0053] As an alternative embodiment, the lubricating member 106 can also be provided at the bottom of the support seat 200, or lubricating members 106 can be provided at both the bottom of the support seat 200 and the upper part of the support platform 100. For example, rollers are provided at the bottom of the support seat 200, and lubricating grease is coated on the upper part of the support platform 100; or lubricating oil or grease is coated at the bottom of the support seat 200, and balls or rollers are provided on the upper part of the support platform 100.

[0054] As Figure 2 and Figure 3 shown, in some embodiments, a vertical plate 101 protrudes from the side of the support platform 100, and the adjusting member 300 includes a lead screw 301 threadedly connected to the vertical plate 101, and one end of the lead screw 301 extending into the support platform 100 is rotatably connected to the support seat 200.

[0055] Exemplarily, an internal threaded hole is provided inside the vertical plate 101, the lead screw 301 is threadedly engaged with the internal threaded hole of the vertical plate 101, a bearing seat is provided inside the support seat 200, and a bearing is installed on the bearing seat. One end of the lead screw 301 extending into the support platform 100 is key-connected to the bearing inside the support seat 200 to form a connection, so that the lead screw 301 can rotate freely relative to the support seat 200.

[0056] When the lead screw 301 rotates under the action of an external force, due to the threaded connection between the lead screw 301 and the vertical plate 101, the rotation of the lead screw will cause synchronous displacement along its axial direction, driving the axle box 400 to perform a lateral displacement action by the lead screw 301. Here, the lateral direction refers to the direction perpendicular to the axle of the wheel set 600 on the horizontal plane. When the axle box 400 is driven to perform a lateral displacement, the axle of the wheel set 600 is synchronously offset, thereby increasing the space between the gearbox 500 and the wheel set 600 to form an assembly gap.

[0057] The structure of the above-designed cooperation and connection between the lead screw 301 and the vertical plate 101 is easy to maintain. Regularly adding lubricating oil or grease can keep it in good working condition. In addition, components such as the lead screw 301 and the ball cage can usually be replaced separately, reducing the maintenance cost. Moreover, in the workshop environment, the threaded structure of the lead screw 301 and the vertical plate 101 is stable and not easily damaged, facilitating the operation of the operators.

[0058] In some embodiments, one end of the adjusting member 300 exposed outside the support platform 100 is configured with a control handle 302, and the shape of the control handle 302 is annular.

[0059] Here, the adjusting member 300 can be a metal part. The annular control handle 302 can facilitate the operator to insert an auxiliary rotating tool to rotate the lead screw 301. For example, by inserting a steel bar into the control handle 302, the acting force arm is increased by using the steel bar, making the rotation of the lead screw 301 more labor-saving.

[0060] Compared with using a motor or other linear drive components, the setting of the lead screw 301 threaded with the vertical plate 101 can eliminate the use of precise and complex linear drive components, with a simple structure, low cost, convenient maintenance, strong versatility, and is beneficial to enhancing the overall convenience of the auxiliary disassembly and assembly tooling.

[0061] As Figure 2 shown, in some embodiments, blocking portions 201 are respectively protrudingly configured at both ends of the support seat 200, and the two blocking portions 201 jointly block the axle box 400 from detaching from the support seat 200.

[0062] Furthermore, the opposite sides of the two blocking portions 201 are inclined, and the two blocking portions 201 jointly enclose an isosceles trapezoid with the short side facing down in the cross-sectional profile. This design can facilitate the clamping of the axle box 400 on the support seat 200. During the displacement process of the support seat 200, the inclined design of the blocking portion 201 can prevent the axle box 400 from shaking with the support seat 200, enhancing the stability of the axle box 400 on the support seat 200.

[0063] In the above embodiments, the blocking portion 201 and the main body portion of the support base 200 may be integrally formed, or the blocking portion 201 and the main body portion of the support base 200 are detachably connected by bolts. The blocking portion 201 and the support base 200 can be made of steel plate materials. For axle boxes 400 of different shapes and types, different blocking portions 201 can be replaced and set accordingly, as long as the fixing effect of the axle box 400 on the support base 200 is ensured.

[0064] As Figure 2 shown, in some embodiments, a baffle 102 is protruded upward from the side edge of the support platform 100, and each baffle 102 encloses a groove-shaped installation space, and the support base 200 is placed in the installation space.

[0065] The baffle 102 in the above embodiments is integrally formed with the support platform 100. By providing the baffle 102, an inner concave installation space is formed by the baffle 102 and the vertical plate 101 together at the upper end of the support platform 100, thereby preventing the support base 200 from detaching from the support platform 100 during displacement and enhancing the stability of the overall structure.

[0066] In addition, due to the provision of the baffle 102, the baffle 102 limits the maximum displacement distance of the support base 200. When an operator manipulates the adjustment component 300 to displace the support base 200, the support base 200 can only be slid to abut against the baffle 102 and cannot be displaced further. Therefore, by designing the reasonable size of the support platform 100 and the position of the baffle 102, the maximum offset distance of the axle box 400 relative to the wheel set 600 can be determined, and the axle box 400 can be prevented from being damaged due to excessive offset and pulling.

[0067] Here, the maximum offset distance of the axle box 400 relative to the wheel set 600 can be determined according to the connection position relationship of the various components of the locomotive, and the embodiments of the present application do not make an absolute limitation thereto.

[0068] In some embodiments, the support platform 100 includes a base 103 and a movable bracket 104 provided on the base 103. The support base 200 is provided on the movable bracket 104, and the height of the movable bracket 104 on the base 103 is adjustable.

[0069] Exemplarily, a linear drive component is installed on the base 103, and the output end of the linear drive component is connected to the movable bracket 104, thereby forming an adjustable height state of the movable bracket 104 on the base 103. Here, the linear drive component can adopt a cylinder, a hydraulic cylinder or a linear drive motor. Considering the large weight of the axle box 400 and the support base 200, it is preferably to adopt a hydraulic drive device to drive the displacement of the movable bracket 104.

[0070] With the above settings, the height adjustment of the movable support 104 on the base 103 enables the support base 200 to adapt to locomotive operation environments of different heights. When the height of the axle box 400 of the locomotive is different from that of the previous axle box 400, the height of the movable support 104 on the base 103 can be adjusted for adaptation, effectively improving the adaptability and versatility of the disassembly and assembly tooling.

[0071] As Figure 1 shown, in some embodiments, the auxiliary disassembly and assembly tooling for the locomotive gearbox 500 further includes an assembly platform 700. The assembly platform 700 is fixedly connected to the support platform 100 and is used for loading the gearbox 500 and the wheel set 600.

[0072] In the above embodiments, a fixture for supporting the wheel set 600, the traction motor, and the gearbox 500 is fixedly provided on the assembly platform 700. The bottom of the assembly platform 700 is a steel plate, and the bottom of the assembly platform 700 is fixedly connected to the base 103 of the support platform 100 by welding, so that the assembly platform 700 and the support platform 100 are integrally fixed. After the bogie of the locomotive is hoisted by an external hoisting device and placed on the assembly platform 700, the axle box 400 is placed on the support platform 100, and subsequent disassembly and assembly work can be carried out.

[0073] The fixation of the assembly platform 700 and the support platform 100 can prevent the axle box 400 from damaging the connecting components due to excessive displacement during the displacement process. At the same time, it is convenient for the operators to observe the size of the assembly gap space.

[0074] Further, a support platform 100 is respectively provided on the opposite sides of the assembly platform 700. An axle box 400 is respectively installed on both sides of the wheel set 600, and the support platform 100 and the axle box 400 are arranged in one-to-one correspondence.

[0075] Generally, the wheel set 600 of an electric locomotive includes two wheels and a wheel axle, and an axle box 400 is respectively installed corresponding to each wheel. Therefore, by providing two support platforms 100, the support platforms 100 can respectively support and fix the axle boxes 400 of the two wheels, ensuring the stability of the axle box 400 during the offset process and preventing the axle box 400 on one side from driving the axle box 400 on the other side to disengage from the wheel set 600 when the axle box 400 on one side offsets.

[0076] It should be noted that in the embodiments of the present application, generally, the axle box 400 on one side is driven to perform a displacement action, and the axle box 400 on the other side remains in its original position. When the axle box 400 is driven to shift, the axle of the wheel set 600 changes from the original vertical placement to an inclined state accordingly. An assembly gap is formed between the inclined axle and the gear box 500. It can be seen that this assembly gap sacrifices part of the deformation redundancy space of the flexible connection. The design of displacing one side of the axle box 400 and keeping the other side of the axle box 400 in its original position can prevent the axle from being overly displaced and pulled to damage the connecting components between it and the gear box 500, facilitating the operator to disassemble and assemble the bearing of the driving gear of the gear box 500 through the assembly gap.

[0077] Since the axle box 400 is displaced horizontally, the displacement of the axle box 400 will synchronously increase the radial distance between it and the gear box 500, forming an approximately triangular assembly gap between the wheel set 600 and the gear box 500. This assembly gap is jointly formed by the radial and axial displacements. This setting can increase the assembly gap, facilitating the operator to perform disassembly and assembly operations on the gear box 500.

[0078] In some embodiments, taking the HXD3D type electric locomotive as an example, both the support platform 100 and the support seat 200 are formed by welding 16 mm steel plates. On the support platform 100, a 10 mm thick steel plate is welded to the upper end of the movable bracket 104, and an installation groove 105 is provided on the thick steel plate for installing a roller. The length of the movable bracket 104 in the transverse direction is designed to match the length of the axle box 400. There is no absolute limit in this embodiment.

[0079] In the auxiliary disassembly and assembly tooling with the above parameters, after the external force drives the screw rod 301 to rotate and the support seat 200 drives the axle box 400 to displace horizontally, the radial distance between the axle box 400 and the gear box 500 can increase by 35 - 40 mm, and the axial distance between the axle box 400 and the gear box 500 can increase by 20 - 25 mm. The increased distances in the radial direction and the axial direction jointly form an assembly gap within a certain range. This assembly gap is sufficient for the operator to disassemble the bearing of the driving gear of the gear box 500, facilitating the disassembly and assembly operations of the gear box 500.

[0080] After considering the specification and practicing the disclosed utility model herein, those skilled in the art will readily conceive of other embodiments of the present application. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include the common general knowledge or conventional technical means in the technical field not disclosed in the present application. The specification and embodiments are only regarded as exemplary, and the true scope and spirit of the present application are pointed out by the following claims.

[0081] It should be understood that the present application is not limited to the exact structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present application is only limited by the appended claims.
