Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to an excavator. Background Technology

[0002] See Figure 3 The existing excavator's gearbox mounting structure mainly includes: the existing cab (8), the existing gearbox mounting bracket (9), the existing gearbox (10), and the existing clutch friction plate (11).

[0003] Currently, mechanical transmission wheeled excavators on the market have been in use for 500-2000 hours. Due to wear, the existing clutch friction plates (11) all need to be replaced. To replace the existing clutch friction plates (11), the existing gearbox (10) needs to be pulled horizontally about 130mm from the engine flywheel housing toward the existing cab (8) before it can be removed.

[0004] Existing shortcomings: 1. The existing structure of the small mechanical wheel excavator is that the existing gearbox (10) is blocked by the existing cab (8), and the existing gearbox mounting bracket (9) is welded to the platform, which will block the horizontal pulling out of the existing gearbox (10). When replacing the existing clutch friction plate (11), it is generally necessary to remove the existing cab (8) or design the existing cab (8) as a hinged installation. When replacing the existing clutch friction plate (11), the existing cab (8) is flipped and raised to a certain height, which increases the workload and difficulty of replacing the clutch friction plate (11). At the same time, the hinged installation without shock absorption structure reduces the comfort of the existing cab (8).

[0005] 2. The existing structure makes it difficult to conveniently observe the wear of the clutch friction plate (11) at any time. Utility Model Content

[0006] The purpose of this invention is to provide an excavator that solves the problem in the prior art of mechanically driven wheeled excavators where the cab needs to be disassembled when replacing the clutch friction plates.

[0007] To achieve the above objectives, the present invention provides an excavator, including a mounting platform. The top of the mounting platform is provided with an engine, a clutch friction plate, and a gearbox arranged sequentially from back to front. The engine and the gearbox are connected via the clutch friction plate, allowing power from the engine to be transmitted to the gearbox. An operating hole is located below the clutch friction plate and extends vertically through the mounting platform. The gearbox is detachably connected to one end of a gearbox mounting bracket, and the other end of the gearbox mounting bracket is detachably connected to the mounting platform. A cab is also located on the top of the mounting platform, situated to the left or right of the gearbox. A cover covers the engine, the clutch friction plate, and the gearbox.

[0008] Furthermore, the front end of the gearbox is fixed to the top end of the gearbox mounting bracket by screws, and the bottom end of the gearbox mounting bracket is fixed to the mounting platform by screws.

[0009] Furthermore, a rotating support seat is provided in front of the gearbox mounting bracket, and the rotating support seat protrudes upward from the mounting platform.

[0010] Furthermore, the rotating support is rotatably connected to one end of the boom, and the other end of the boom is rotatably connected to the stick, which is equipped with a bucket.

[0011] Furthermore, a through hole is provided at the lower front of the gearbox, the through hole is disposed on the mounting platform, the through hole extends vertically through the mounting platform, and the through hole is located behind the gearbox mounting bracket.

[0012] Furthermore, the through hole is a round hole, and the operating hole is a rectangular hole.

[0013] Furthermore, a counterweight is provided on the top of the mounting platform, and the counterweight is located behind the engine.

[0014] Furthermore, several shock absorbers are provided between the bottom of the cab and the mounting platform.

[0015] Furthermore, the shock absorbers are respectively installed at the four corners of the bottom of the cab.

[0016] Furthermore, the bottom of the installation platform is equipped with a wheeled walking mechanism.

[0017] In summary, the application of the technical solution of this utility model has the following beneficial effects: The structure of this utility model is reasonable. (1) By setting up an installation platform, the top of the installation platform is provided with an engine, clutch friction plate and gearbox arranged sequentially from back to front. The engine and gearbox are connected through the clutch friction plate so that the power of the engine can be transmitted to the gearbox. Thus, the power of the engine can be transmitted to the gearbox through the clutch friction plate. (2) An operating hole is provided below the clutch friction plate, which is located on the mounting platform and extends vertically through the platform. One end of the gearbox is detachably connected to the gearbox mounting bracket, and the other end of the gearbox mounting bracket is detachably connected to the mounting platform. A cab is also provided on the top of the mounting platform, located on one side of the gearbox in the left-right direction. The engine, clutch friction plate, and gearbox are covered by a cover. This ensures that the top of the gearbox is no longer obstructed by the cab. When the clutch friction plate needs to be replaced, the cover can be removed first, followed by the gearbox mounting bracket and the gearbox, and then the clutch friction plate can be replaced without removing or flipping the cab. Furthermore, the operating hole below the clutch friction plate allows for routine inspection of the wear condition of the clutch friction plate and provides operating space for replacement. As can be seen from the above analysis, this utility model eliminates the need to disassemble or flip the cab when replacing the clutch friction plate, effectively improving maintainability and efficiency.

An operating hole 101 is provided below the clutch friction plate 3. The operating hole 101 is located on the mounting platform 1 and extends vertically through the mounting platform 1. The gearbox 4 is detachably connected to one end of the gearbox mounting bracket 5, and the other end of the gearbox mounting bracket 5 is detachably connected to the mounting platform 1. The top of the mounting platform 1 is also provided with a cab 6, which is located on one side of the gearbox 4 in the left-right direction (i.e., the left or right side). The engine 2, the clutch friction plate 3, and the gearbox 4 are covered with a cover (not shown in the figure). Function: (1) By setting up a mounting platform, the top of the mounting platform is provided with an engine, a clutch friction plate, and a gearbox arranged sequentially from back to front. The engine and the gearbox are connected through the clutch friction plate so that the power of the engine can be transmitted to the gearbox. Thus, the power of the engine can be transmitted to the gearbox through the clutch friction plate. (2) An operating hole is provided below the clutch friction plate, which is located on the mounting platform and extends vertically through the platform. One end of the gearbox is detachably connected to the gearbox mounting bracket, and the other end of the gearbox mounting bracket is detachably connected to the mounting platform. A cab is also provided on the top of the mounting platform, located on one side of the gearbox in the left-right direction. The engine, clutch friction plate, and gearbox are covered by a cover. This ensures that the top of the gearbox is no longer obstructed by the cab. When the clutch friction plate needs to be replaced, the cover can be removed first, followed by the gearbox mounting bracket and the gearbox, and then the clutch friction plate can be replaced without removing or flipping the cab. Furthermore, the operating hole below the clutch friction plate allows for routine inspection of the wear condition of the clutch friction plate and provides operating space for replacement. As can be seen from the above analysis, this utility model eliminates the need to disassemble or flip the cab when replacing the clutch friction plate, effectively improving maintainability and efficiency.

[0025] Specifically, the front end of the gearbox 4 is fixed to the top of the gearbox mounting bracket 5 with screws, and the bottom end of the gearbox mounting bracket 5 is fixed to the mounting platform 1 with screws.
