Description

Technical Field

[0001] This utility model relates to the field of gearbox and electric drive repair, specifically to a multi-directional tilting repair trolley. Background Technology

[0002] Most existing gearbox and electric drive disassembly trolleys use bolts to fix the gearbox housing to the swing arm, which does not allow for horizontal rotation or multi-angle positioning of the gearbox. This prevents operators from disassembling the gearbox housing at more convenient angles. Current structures can only rotate the housing 180 degrees in both directions, but the housing can only maintain one posture on the swing arm. Operators need to frequently walk around the repair trolley, change body postures, and even look up to disassemble the gearbox, which is very inconvenient, does not conform to ergonomics, and increases disassembly time, making it time-consuming and labor-intensive.

[0003] While the aforementioned repair trolley can achieve the purpose of disassembling the gearbox and electric drive, it is limited by the fixed structure of the tilting arm, which is bulky and cannot be made simple and lightweight. For repair workers, it requires constantly tilting the gearbox or moving around the trolley to change positions, which is very energy-consuming, time-consuming, and inefficient. It also poses a safety hazard of missing bolts, and the fixed operating position is inconvenient for manual operation. Utility Model Content

[0021] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0022] like Figure 1 The diagram shown is an overall schematic diagram of a multi-directional flipping repair trolley according to one embodiment of the present invention. Figure 1 The rework trolley may include a horizontal rotating assembly, a vertical tilting assembly, a receiving assembly, and a motion assembly. The horizontal rotating assembly is used to place the product and can rotate the product on a horizontal plane. The vertical tilting assembly is used to rotate the horizontal rotating assembly in a vertical plane, and the horizontal rotating assembly is mounted on the vertical tilting assembly. At least a portion of the receiving assembly is located directly below the horizontal rotating assembly. The motion assembly is connected to the vertical tilting assembly and the receiving assembly.

[0023] Therefore, by using, as Figure 1The illustrated multi-directional tilting repair trolley allows the gearbox or electric drive housing to be manually hoisted and secured to a horizontal rotating assembly. Manual operation of the horizontal rotating assembly enables rotation at any angle within the horizontal plane to secure the product requiring repair. Manual operation of the vertical tilting assembly allows tilting and securing of the gearbox or electric drive housing at any angle within the vertical plane. This overcomes the technical shortcomings of existing technologies, such as the fixed tilting arm, bulky structure, difficulty in operation for maintenance workers, and low maintenance efficiency.

[0024] Specifically, in one embodiment of this utility model, such as Figure 2 As shown, the horizontal rotary assembly may further include a product fixing mechanism and a rotary platform 1. The product fixing mechanism is used to fix the product. The rotary platform 1 is used to mount the product fixing mechanism, and the product fixing mechanism is rotatable on the rotary platform 1. The specific structure for fixing the product to the repair trolley can be of various forms known to those skilled in the art, including but not limited to bolt fixing, cylinder clamping, and mechanical grippers.

[0025] In such Figure 2 In the schematic diagram of the horizontal rotating assembly shown, considering that the product to be repaired needs to be fixed on the repair trolley for easy operation by maintenance personnel during the repair process, in order to ensure that the product is fixed on the repair trolley on the one hand, and can also rotate horizontally on the repair trolley on the other hand, in one embodiment of this utility model, as shown... Figure 2 As shown, the rotary platform 1 is provided with a through hole for placing products, and the product fixing mechanism may include an upper fixing plate 21, a lower fixing plate 22, and a fixing column 23. The upper fixing plate 21 is located above the rotary platform 1. The lower fixing plate 22 is located below the rotary platform 1. The fixing column 23 is located within the through hole of the rotary platform 1 and is connected to the upper fixing plate 21 and the lower fixing plate 22. Considering the convenience of placing products onto the repair trolley, in a preferred embodiment of this utility model, the upper fixing plate 21, the lower fixing plate 22, and the through hole have openings on the side away from the vertical flipping assembly.

[0026] In such Figure 2 In the horizontal rotary assembly shown, the product is fixed to the product fixing mechanism, and then the product fixing mechanism is rotated to achieve horizontal rotation of the product. Considering that the product fixing mechanism may detach from the rotary platform 1 during rotation without restraint, in order to make the product rotation smoother and more stable, and also to ensure the stability of the product rotation, at least one cam follower 24 is provided on the rotary platform 1, and the bottom of the upper fixing plate 21 is provided with a groove that can match the cam follower. Through the limiting effect of the groove and the cam follower 24, the product fixing mechanism can operate stably and smoothly during rotation.

[0027] Furthermore, during maintenance, considering the need to lock the product's angle on the horizontal rotating assembly after rotating it to a suitable angle, in one embodiment of this invention, at least one first locking member 25 is provided on the upper fixing plate 21. Pulling out the first locking member 25 allows the product fixing mechanism to rotate on the rotating platform 1; inserting the first locking member 25 prevents the product fixing mechanism from rotating on the rotating platform 1, thereby fixing the product at the desired angle. The specific structure for fixing the product angle can be of various forms known to those skilled in the art, including but not limited to bolt fixing, cylinder clamping, and hydraulic devices.

[0028] like Figure 3 The diagram shown is a schematic representation of a vertically flipping assembly according to one embodiment of the present invention. Figure 3 In this configuration, the vertical flipping assembly may include a vertical turntable 31 and a base 32. The vertical turntable 31 can be connected to a horizontal rotation assembly. The base 32 is hinged to the vertical turntable 31 and fixedly connected to a motion assembly. Therefore, by using... Figure 3 The vertical flipping component shown allows maintenance personnel to manually rotate the vertical turntable 31, thereby enabling the horizontal rotary platform to flip at any angle in the vertical direction.

[0029] exist Figure 3 In the vertical flipping assembly shown, considering that the returned products are sometimes very heavy, manually rotating the vertical turntable 31 directly is very labor-intensive. To ensure work efficiency and save operator effort, in one embodiment of this invention, a shaft hole is provided on the base 32, and the vertical flipping assembly includes a shaft 33, a rocker arm 34, and a gear set 35. The shaft 33 is disposed within the shaft hole and connected to the vertical turntable 31. The rocker arm 34 is rocked to input rotational force. The gear set 35 meshes with the shaft 33 and the rocker arm 34, driving the shaft 33 to rotate as the rocker arm 34 rotates. While ensuring the transmission structure saves effort, this transmission structure can be of various forms known to those skilled in the art, including but not limited to gear sets, linkage structures, and motor drives.

[0030] Furthermore, during maintenance, considering the need to lock the product's angle on the vertical flipping assembly after flipping it to a suitable angle, in one embodiment of this invention, a second locking member 36 is provided on the base 32. Pulling out the second locking member 36 allows the vertical turntable 31 to rotate vertically; inserting the second locking member 36 prevents the vertical turntable 31 from rotating vertically, thus fixing the product at the desired angle. The specific structure for fixing the product angle can be of various forms known to those skilled in the art, including but not limited to bolt fixing, cylinder clamping, and hydraulic devices.

[0031] like Figure 4 The diagram shown is a schematic representation of a receiving assembly according to one embodiment of the present invention. Figure 4 The receiving assembly may include a filter screen 41 and a chassis 42. The filter screen 41 is used to filter falling solid parts, thereby preventing safety issues such as loose bolts. The chassis 42 is detachably disposed below the filter screen 42 for collecting engine oil dripping during gearbox or electric drive housing maintenance.

[0032] In summary, this utility model allows for the manual hoisting and fixing of the gearbox or electric drive housing requiring repair onto the product fixing mechanism of the horizontal rotating assembly. Pulling open the first locking member 25 allows the gearbox or electric drive housing to rotate at any angle in the horizontal direction. Once a suitable angle is reached, inserting the first locking member 25 locks the product's angle on the horizontal rotating platform. Pulling open the second locking member 36 and shaking the rocker arm 34, which, through the operation of the gear set 35, drives the rotating shaft 33 to rotate, allows the gearbox or electric drive housing to rotate at any angle in the vertical direction. Locking the second locking member 36 after reaching a suitable angle fixes the gearbox or electric drive housing's position, facilitating manual operation. Furthermore, a receiving assembly is provided below the horizontal rotating assembly, where the filter screen 41 filters solid parts that fall during repair, and the chassis 42 collects dripping oil.
