[0004] Currently, four motor outriggers are used to fix the motor to the excavator chassis platform, and these four outriggers adopt the same structural configuration.

[0005] Because the motor is small in size, when four identical motor outriggers are used to install and fix the motor, the center position of the four motor outriggers is not consistent with the overall center of gravity of the motor and main pump. This results in uneven stress on the four motor outriggers, affecting their strength and lifespan, and may even affect the overall stability of the excavator. Utility Model Content

[0030] Example 1

[0031] First, the application scenario of this embodiment will be explained.

[0032] The excavator motor fixing device proposed in this embodiment is used to fix the excavator motor to the excavator platform, which refers to the excavator chassis platform. The excavator platform includes a main platform, a left platform, and a right platform. The right end of the main platform is connected to the main beam of the right platform, and the left end of the main platform is connected to the main beam of the left platform. A center upright plate is provided in the middle of the main platform, a rear upright plate is provided at the rear of the main platform, and a bottom plate is provided at the bottom of the main platform. The two ends of the bottom plate, the center upright plate, and the rear upright plate are respectively connected to the main beam of the left platform and the main beam of the right platform.

[0033] Currently, four motor outriggers are used to fix the motor to the excavator chassis platform. These four outriggers have the same structure: two outriggers are connected to the right platform main beam, one outrigger is connected to the center plate of the main platform, and the last outrigger is connected to the rear plate of the main platform. The motor needs to be connected to the main pump. Due to the small size of the motor, the overall center of gravity of the motor and the main pump will be biased towards the main pump. When the motor is installed and fixed using the existing method of motor outriggers, the center position of the four motor outriggers is not consistent with the overall center of gravity of the motor and the main pump. This results in uneven stress on the four motor outriggers, affecting their strength and lifespan, and may even affect the overall stability of the excavator.

[0034] If one of the outriggers is simply lengthened or enlarged, firstly, the chassis platform has many parts, making it inconvenient to arrange the parts after lengthening or enlarging it; secondly, when it is lengthened or enlarged, the distance between the outrigger's fulcrum and the stress point increases, thus affecting the outrigger's strength and lifespan.

[0035] To ensure that the center positions of the four motor outriggers are aligned with the overall center of gravity of the motor and main pump, while also guaranteeing the strength and lifespan of the outriggers, this embodiment discloses an excavator motor fixing device, such as... Figure 1 , Figure 2 As shown, it includes: left front outrigger 1, left rear outrigger 2, right front outrigger 3 and right rear outrigger 4; right front outrigger 3 and right rear outrigger 4 are connected to the main beam 5 of the right platform of the excavator; left front outrigger 1 is connected to the center plate of the main platform of the excavator.

[0036] The left rear outrigger 2 includes a horizontal brace 2-4 and a vertical leg. The vertical leg is mounted on the horizontal brace 2-4. One end of the horizontal brace 2-4 is connected to the main beam 6 of the left platform of the excavator, and the other end of the horizontal brace is connected to the main beam 5 of the right platform of the excavator.

[0037] In this embodiment, motor mounting holes are provided on the right front outrigger 3, right rear outrigger 4, left front outrigger 1, and vertical outrigger. The center of the four motor mounting holes is aligned with the overall center of gravity of the motor and main pump. This ensures that the force on the four outriggers is basically consistent, improving the stability of the motor installation. The two ends of the cross brace 2-4 are connected to the main beam 6 of the excavator's left platform and the main beam 5 of the excavator's right platform. The vertical outrigger is installed on the cross brace 2-4, enabling the left rear outrigger 2 to withstand greater loads. Even under harsh working conditions, the outrigger strength remains sufficient to ensure the stability of the motor.

[0038] like Figure 1 As shown, the right front outrigger and the right rear outrigger are fixed at intervals along the length of the main beam of the right platform of the excavator.

[0039] The right front outrigger 3 and the right rear outrigger 4 are located on the right side of the right platform main beam 5 of the excavator; the left front outrigger 1 and the left rear outrigger 2 are located on the left side of the right platform main beam 5 of the excavator.

[0040] In addition to being connected to the center plate, the left front outrigger 1 is also connected to the floor plate of the excavator's main platform. This enhances the overall strength of the left front outrigger 1.

[0041] The left front outrigger, right front outrigger, and right rear outrigger have the same structure, each including a second reinforcing plate, a second mounting plate, and two symmetrically arranged curved plates. The second reinforcing plate is located between the two curved plates and is fixed to one end of the two curved plates. The other ends of the two curved plates are connected to the main beam of the right platform of the excavator or the center plate of the main platform of the excavator.

[0042] The motor mounting hole is set on the second mounting plate, and a second reinforcing plate is set between the two bent plates to improve the strength of the outrigger and ensure the stability of the outrigger structure.

[0043] like Figure 2 As shown, the vertical leg includes a first reinforcing plate 2-3, two first support plates 2-2 and a first mounting plate 2-1. The two first support plates 2-2 are arranged opposite to each other on the cross brace 2-4. The first reinforcing plate 2-3 is connected to the two first support plates 2-2, and the first mounting plate 2-1 is fixed to the two first support plates 2-2.

[0044] Among them, the cross brace 2-4 adopts a U-shaped structure, with the opening of the U-shaped structure facing downwards from the excavator platform. The vertical leg is installed on the upper surface of the U-shaped structure, and the open end of the cross brace 2-4 is connected to the bottom plate of the excavator main platform.

[0045] Crack prevention openings are provided on the cross braces 2-4.

[0046] The cross brace adopts a U-shaped structure, with Q355B steel plate, 12mm thick, and a 200mm long contact surface with the vertical leg. The corner radius reaches 30mm. There are anti-crack openings on both sides of the cross brace, which connect to the main beams of the left and right platforms. The bottom two sides rest on the base plate of the excavator's main platform. This structure, which uses a cross brace and a vertical leg, is more stable and stronger than the traditional single-leg structure.

[0047] The dimensions of the first mounting plate and the second mounting plate are both 215*176*25mm, the dimensions of the first support plate are 210*140*20mm, the dimensions of the first reinforcing plate and the second reinforcing plate are both made of 20mm thick sheet material, and the first mounting plate, the first reinforcing plate, the first support plate and the cross brace are all connected by double-sided welding, resulting in high strength.

[0048] The motor mounting holes on both the first and second mounting plates are sized to match the motor, such as holes with a diameter of 29mm.

[0049] In addition, weight-reducing holes are provided on both the first and second reinforcing plates to reduce the weight of the outriggers as much as possible while ensuring strength.

[0050] This embodiment proposes an excavator motor fixing device that uses outriggers with different structures to ensure that the overall center of gravity of the motor and main pump is consistent with the center position of the four motor outriggers, thereby improving the strength and life of the motor outriggers and the overall stability of the excavator.
