A slot 5 is provided on the top of the mounting plate 4, and the steering pump 6 is installed in the slot 5 for fixation. When the steering pump 6 is started, a slide groove 9 is provided at the four corners of the top of the base 2, and a pulley 10 is provided on the inner wall of the slide groove 9, so that the steering pump 6 drives the mounting plate 4 to rotate, and the mounting plate 4 is fixed by the rotating shaft 3 and the pulley 10. When the excavator carries soil and travels to complex terrain, the fuselage is affected by the weight of the soil in the bucket, thereby causing the fuselage to bump. A fixed base 7 is provided at the center of the bottom of the inner cavity of the mounting shell 1, and a hydraulic shock absorber 8 is provided on the top of the fixed base 7. The hydraulic shock absorber 8 is used to cushion the base 2, so that the excavator can smoothly travel over complex terrain and avoid the body bumping, which may cause damage to internal parts. Example

[0028] like Figure 1-6 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, an oil transfer tank 11 is opened on the inner wall of the base 2, and the center of the bottom of the inner cavity of the oil transfer tank 11 is fixedly connected to the top of the hydraulic shock absorber 8, and a plurality of unloading bases 12 are fixedly connected around the bottom of the inner cavity of the oil transfer tank 11, and the bottom of the unloading base 12 is rotatably connected to a hydraulic rod 13, and one end of the hydraulic rod 13 is rotatably connected to a supporting slider 14, and the inner wall of the supporting slider 14 is slidably connected to the outer wall of the hydraulic shock absorber 8, and an oil pump 15 is fixedly connected to the center of the bottom of the inner wall of the mounting shell 1, and the output end of the oil pump 15 is fixedly connected to the bottom of the hydraulic shock absorber 8.

[0029] In this embodiment, an oil pump 15 is provided at the center of the bottom of the inner wall of the mounting housing 1, and the output end of the oil pump 15 is connected to the bottom of the hydraulic shock absorber 8, so that the base 2 is fixed by the hydraulic shock absorber 8. When the excavator is excavating and transporting soil, the body is affected by the weight of the soil in the bucket, and the body becomes unstable, the oil pump 15 is started to make the hydraulic oil flow along the hydraulic shock absorber 8 into the oil tank 11. By providing a plurality of unloading bases 12 around the bottom of the inner cavity of the oil tank 11, the hydraulic oil flows along the unloading base 12. The hydraulic pressure flows into the hydraulic rod 13 provided at the bottom thereof, thereby using the hydraulic rod 13 to support the inclined side. By providing a supporting slider 14 at one end of the hydraulic rod 13, the supporting slider 14 slides on the outer wall of the hydraulic shock absorber 8. By adjusting the height of the output end of the hydraulic shock absorber 8, the hydraulic rods 13 on both sides are kept horizontal, thereby ensuring the stability of the center of gravity of the excavator and solving the problem that the traditional excavator is easily unstable in the steering process due to the influence of the weight of the soil in the bucket during operation, thereby causing the excavator to roll over. Example

[0030] like Figure 1-6 As shown, based on Example 1, the utility model provides a technical solution: preferably, the outer wall of the hydraulic shock absorber 8 is fixedly connected to the limiting groove 16, the inner wall of the limiting groove 16 is slidably connected to the limiting block 17, and one end of the limiting block 17 is fixedly connected to the inner wall of the supporting slider 14.

[0031] In this embodiment, a limit groove 16 is provided on the outer wall of the hydraulic shock absorber 8, and the limit groove 16 is used to fix the limit block 17 provided on the inner wall of the support slider 14. When the center of gravity of the excavator is unstable during the steering process, the limit groove 16 is used to limit the support slider 14 to avoid a large deviation of the center of gravity, which causes the excavator to have no time to adjust the center of gravity, thereby causing the problem of rollover. Example

[0032] like Figure 1-6 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, one end of the inner wall of the limiting groove 16 is fixedly connected to a shock-absorbing spring 18, one end of the shock-absorbing spring 18 is fixedly connected to a clamping block 19, one end of the clamping block 19 is clamped to the top of the limiting block 17, and the end of the hydraulic shock absorber 8 away from the limiting block 17 is fixedly connected to a fixed block 20, and one end of the fixed block 20 is clamped to the top of the clamping block 19.

[0033] In this embodiment, a shock-absorbing spring 18 is provided at one end of the inner wall of the limit groove 16, and a block 19 is provided at one end of the shock-absorbing spring 18. When the center of gravity shifts during the steering process of the excavator, the limit groove 16 and the block 19 are used to fix the limit block 17. When the offset angle is large, in order to protect its internal parts, the shock-absorbing spring 18 is used to increase the gap between the block 19 and the limit block 17 to avoid damage to the support slider 14 during the process of adjusting the center of gravity. A fixed block 20 is provided at one end of the limit block 17 of the hydraulic shock absorber 8, and the fixed block 20 is used to limit the top of the block 19 to avoid the support slider 14 and the hydraulic shock absorber 8 from exceeding a dangerous angle, resulting in scraping between the two during the process of adjusting the center of gravity, thereby causing damage to the shock absorbing equipment.

[0034] The following is a detailed description of the working principle of the steering pump mounting bracket for excavators.

[0035] like Figure 1-6As shown, a base 2 is provided on the top of the mounting shell 1, a rotating shaft 3 is provided at the center of the top of the base 2, the rotating shaft 3 is used to lift the mounting plate 4 provided on the top, a card slot 5 is provided on the top of the mounting plate 4, and the steering pump 6 is installed in the card slot 5 for fixing. When the steering pump 6 is started, a slide 9 is provided at the four corners of the top of the base 2, and a pulley 10 is provided on the inner wall of the slide 9. When the steering pump 6 drives the mounting plate 4 to rotate, the mounting plate 4 is fixed by the rotating shaft 3 and the pulley 10. When the excavator carries soil and travels to complex terrain, the fuselage is subjected to the weight of the soil in the bucket, thereby causing the fuselage to bump. A fixed base 7 is provided at the center of the bottom of the inner cavity of the mounting shell 1, and a hydraulic shock absorber 8 is provided on the top of the fixed base 7. The hydraulic shock absorber 8 cushions the base 2, so that the excavator can smoothly pass through complex terrain and avoid the body from shaking, which may cause damage to internal parts. An oil pump 15 is arranged at the center of the bottom of the inner wall of the mounting shell 1, and the output end of the oil pump 15 is connected to the bottom of the hydraulic shock absorber 8, so that the base 2 is fixed by the hydraulic shock absorber 8. When the excavator is digging and transporting soil, the body is affected by the weight of the soil in the bucket, and when the body is unstable, the oil pump 15 is started to make the hydraulic oil flow along the hydraulic shock absorber 8 into the oil tank 11, and a number of unloading bases 12 are arranged around the bottom of the inner cavity of the oil tank 11, so that the hydraulic oil flows along the unloading base 12 into the hydraulic rod 13 arranged at the bottom thereof, so that the hydraulic rod 13 supports the inclined side, and a supporting slider 14 is provided at one end of the hydraulic rod 13 so that the supporting slider 14 slides on the outer wall of the hydraulic shock absorber 8. By adjusting the height of the output end of the hydraulic shock absorber 8, the hydraulic rods 13 on both sides are level, thereby ensuring the stability of the center of gravity of the excavator, solving the problem that the center of gravity of the traditional excavator is easily unstable during the steering process due to the influence of the weight of the soil in the bucket, thereby causing the excavator to roll over. By providing a limiting groove 16 on the outer wall of the hydraulic shock absorber 8, the limiting groove 16 is used to fix the limiting block 17 provided on the inner wall of the supporting slider 14. When the center of gravity of the excavator is unstable during the steering process, the limiting groove 16 is used to limit the supporting slider 14 to avoid the center of gravity from being unstable. The large deviation amplitude makes it impossible for the excavator to adjust its center of gravity in time, thus causing the problem of rollover. A shock-absorbing spring 18 is provided at one end of the inner wall of the limit groove 16, and a block 19 is provided at one end of the shock-absorbing spring 18. When the center of gravity shifts during the steering process of the excavator, the limit groove 16 and the block 19 are used to fix the limit block 17. When the deviation angle is large, in order to protect its internal parts, the shock-absorbing spring 18 is used to increase the gap between the block 19 and the limit block 17 to avoid damage to the support slider 14 during the process of adjusting the center of gravity. A fixed block 20 is provided at one end of the limit block 17 of the hydraulic shock absorber 8 principle, and the fixed block 20 is used to limit the top of the block 19 to avoid the support slider 14 and the hydraulic shock absorber 8 from exceeding a dangerous angle.As a result, the two will scrape against each other during the process of adjusting the center of gravity, causing damage to the shock absorbing equipment.

[0036] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
