Description

Technical Field

[0001] This utility model relates to the field of gearbox assembly technology, specifically a flipping tool for gearbox assembly. Background Technology

[0002] The hydraulic high-frequency vibratory pile driver is a new type of pile driving equipment that can convert excavators into pile drivers to drive finished piles into the ground, thus expanding the excavator's functionality. Compared with traditional hydraulic vibratory hammers, the hydraulic high-frequency vibratory pile driver has advantages such as high efficiency, low vibration, low noise, no pollution, and simple structure, conforming to current environmental protection concepts. This product is widely used in pile foundation construction for tunnels, bridges, and docks, and has been developed into a series of products. The gearbox is the core component of the hydraulic high-frequency vibratory pile driver, consisting of internal parts such as the gearbox body, drive shaft, gear assembly, eccentric block, spacer, bearings, and bearing housing. It is responsible for power transmission, excitation force generation, frequency adjustment, and energy conversion, ensuring the equipment operates efficiently and stably.

[0003] The following problems exist in the assembly process of the gearbox of the hydraulic high-frequency vibratory pile driver:

[0004] 1. If the gearbox is placed horizontally, some components such as the drive shaft, gear assembly, and eccentric block are quite heavy, making them difficult to move and install, and increasing the labor intensity for installers. If the gearbox is simply laid flat on the workbench for installation, it takes a long time to level the sides of the gearbox, and multiple flipping and leveling operations are required during the installation process, which affects work efficiency.

[0005] 2. If the housing is placed horizontally, the gear assembly, bearings and bearing housings have a mating relationship and require external force to press in, which will result in uneven assembly pressure and affect the assembly accuracy.

[0006] In view of this, there is an urgent need for a flipping tool for gearbox assembly to overcome the shortcomings of the existing technology. Utility Model Content

[0007] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A gearbox assembly flipping fixture includes: a frame, a mounting bracket, and a limiting mechanism, wherein the mounting bracket is horizontally rotatably mounted on the frame;

[0010] The limiting mechanism includes a rotating disk and a limiting pin. The rotating disk is disposed on one side of the mounting bracket and rotates synchronously and coaxially with the mounting bracket. A plurality of insertion holes are distributed circumferentially on the rotating disk. The limiting pin is horizontally slidably disposed on the frame. When the rotating disk rotates, the plurality of insertion holes pass through the limiting pin in sequence.

[0011] The socket is provided with eight holes, which are evenly distributed in a circle on the rotating disk.

[0012] The bracket is provided with a limit block, the limit block is provided with a limit hole, and the limit pin is slidably disposed at the limit hole.

[0013] The limiting block is provided with a first sliding hole and a second sliding hole on the circumferential side of the limiting hole. The second sliding hole extends circumferentially along the limiting hole, and the first sliding hole extends along the sliding direction of the limiting pin. The second sliding hole communicates with the side of the first sliding hole near the mounting bracket. The limiting pin is provided with an operating rod in the circumferential direction, and the operating rod passes through the first sliding hole or the second sliding hole.

[0014] The end of the limiting pin near the mounting bracket is hemispherical.

[0015] The mounting bracket includes a base plate and frame plates disposed at both ends of the base plate, with both frame plates rotatably mounted on the frame.

[0016] The frame is provided with two support columns, and the two frame plates are respectively mounted on the two support columns via bearings.

[0017] Several fixing holes are provided on both sides of the base plate.

[0018] Auxiliary support plates are provided on opposite sides of the two support columns, and the two auxiliary support plates extend to both sides of the mounting bracket.

[0019] The support column is provided with a shaft, the shaft is provided with a connecting plate, and the auxiliary support plate is provided at the suspension end of the connecting plate.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0029] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

[0030] refer to Figures 1-3 The gearbox assembly flipping fixture shown includes: a frame 1, a mounting bracket 2, and a limiting mechanism. The mounting bracket 2 is horizontally rotatably mounted on the frame 1.

[0031] The limiting mechanism includes a rotating disk 3 and a limiting pin 4. The rotating disk 3 is located on one side of the mounting bracket 2 and rotates synchronously and coaxially with the mounting bracket 2 (that is, the rotating disk 3 and the mounting bracket 2 are fixed on the frame 1 through the same axis). The rotating disk 3 has a number of insertion holes 31 distributed in a circle. The limiting pin 4 is horizontally slidably set on the frame 1. When the rotating disk 3 rotates, the number of insertion holes 31 pass through the limiting pin 4 in sequence.

[0032] Based on the above structure, in use, the gearbox 8 is fixed on the mounting bracket 2, the limiting pin 4 is pulled out from the insertion hole 31, and then the mounting bracket 2 is rotated to adjust the gearbox to a suitable angle (the distribution of several insertion holes 31 is adapted to multiple processing angles of the gearbox). Then, the limiting pin 4 is inserted into the corresponding insertion hole 31. At this time, the position of the rotating disk 3 is fixed, the angle of the mounting bracket 2 is fixed, and the angle of the gearbox is fixed, which facilitates the processing of the gearbox. When the limiting pin 4 is inserted into different insertion holes 31, the gearbox is at different processing angles, which facilitates different processing and assembly steps of the gearbox and improves the convenience and efficiency of gearbox processing.

[0033] Further optimization involves providing eight sockets 31, which are evenly distributed in a circle on the rotating disk 3. When the limiting pin 4 is inserted into different sockets 31, the gearbox is at different angles such as 0°, 45°, and 90°.

[0034] like Figure 3 and Figure 4 As shown, a limit block 5 is provided on the frame 1, and a limit hole is provided on the limit block 5. The limit pin 4 is slidably disposed at the limit hole. Furthermore, a first sliding hole 51 and a second sliding hole 52 are provided on the circumferential side of the limit hole on the limit block 5. The second sliding hole 52 extends circumferentially along the limit hole, and the first sliding hole 51 extends along the sliding direction of the limit pin 4. The second sliding hole 52 communicates with the side of the first sliding hole 51 near the mounting bracket 2. An operating rod 41 is provided circumferentially on the limit pin 4. The operating rod 41 passes through... The limit pin 4 is positioned at either the first sliding hole 51 or the second sliding hole 52. When the operating rod 41 slides within the first sliding hole 51, it controls the insertion and removal of the limit pin 4 into the insertion hole 31. When the limit pin 4 is inserted into the insertion hole 31, the operating rod 41 rotates into the second sliding hole 52, thereby restricting the position of the limit pin 4 and maintaining its insertion into the insertion hole 31. Furthermore, the end of the limit pin 4 near the mounting bracket 2 is hemispherical, facilitating the insertion of the limit pin 4 into the insertion hole 31.

[0035] like Figure 1 and Figure 2 As shown, the mounting bracket 2 specifically includes a base plate 21 and frame plates 22 disposed at both ends of the base plate 21. Both frame plates 22 are rotatably mounted on the frame body 1. Several fixing holes 23 are provided on both sides of the base plate 21. In this way, the base plate 21 is supported by the two frame plates 22, which improves the stability of the base plate 21. The gearbox is fixed to the base plate 21 by bolts through the several fixing holes 23 on the base plate 21. Furthermore, there are multiple sets of several fixing holes 23 to accommodate the processing of gearboxes of different specifications.

[0036] like Figure 1 and Figure 2 As shown, the frame 1 is provided with two support columns 11, and the two frame plates 22 are respectively set on the two support columns 11 through bearings. In this way, the mounting bracket 2 is supported from both sides, which improves the stability of the support.

[0037] Further optimization involves providing auxiliary support plates 6 on opposite sides of the two support columns 11. Specifically, a shaft 7 is mounted on the support column 11, and a connecting plate 71 is mounted on the shaft 7. The auxiliary support plates 6 are positioned at the suspension end of the connecting plate 71, with the two auxiliary support plates 6 extending to both sides of the mounting bracket 2. The cooperation between the shaft 7 and the connecting plate 71 ensures the normal installation of the auxiliary support plates 6, while also allowing the auxiliary support plates 6 to adjust their angle according to the rotation angle of the gearbox. To facilitate the positioning of the auxiliary gearbox, the auxiliary support plates 6 are made of metal plates of different sizes depending on the rotation angle of the gearbox. Two holes for bolts to pass through are provided on the auxiliary support plates 6, corresponding to two different sizes of gearboxes, and can hold the gearbox in place, providing auxiliary fixation. It should be noted that during processing, different sizes and shapes of auxiliary support plates 6 are used depending on the size of the gearbox and the different angles of gearbox processing to achieve the auxiliary fixation function.

[0038] In summary, during use, the gearbox is fixed on the mounting bracket 2, the limiting pin 4 is pulled out from the insertion hole 31, the mounting bracket 2 is rotated to adjust the gearbox to a suitable angle, and then the limiting pin 4 is inserted into the corresponding insertion hole 31. At this time, the position of the rotating disk 3 is fixed, the angle of the mounting bracket 2 is fixed, and thus the angle of the gearbox is fixed, which facilitates the processing of the gearbox. When the limiting pin 4 is inserted into different insertion holes 31, the gearbox is at different processing angles, which facilitates different processing and assembly steps of the gearbox, improves the convenience and efficiency of gearbox processing, and ensures the processing accuracy of the gearbox.

[0039] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
