[0023] Example

[0024] Referring to Figures 1-4, an embodiment of this utility model is provided, which offers a conveniently installed excavator underframe, comprising:

[0025] The system includes a fixed plate 101, a limiting plate 102 fixedly installed at the end of the fixed plate 101, a support rod 103 fixedly connected to the surface of the limiting plate 102, a hinge piece 104 rotatably installed at the end of the support rod 103, a locking assembly 105 fixedly installed on the side surface of the support rod 103, an adjustment assembly 106 rotatably installed in the center of the locking assembly 105, a fixing frame 107 used in conjunction with the adjustment assembly 106, a limiting frame 108 used in conjunction with the fixing frame 107, and a stepping assembly 109 rotatably installed on the inner surface of the limiting frame 108.

[0026] The locking assembly 105 includes a locking plate 105a, a rotating shaft 105b rotatably mounted on the side surface of the locking plate 105a, and a limiting sleeve 105c sleeved on the outer surface of the rotating shaft 105b.

[0027] Two sets of locking components 105 are provided, and the locking components 105 are used in conjunction with the adjustment components 106.

[0028] Specifically, the basic positioning and installation are first achieved through the fixing plate 101 and the limiting plate 102, and the support rod 103 cooperates with the hinge piece 104 to form an adjustable support structure; the two sets of locking components 105 realize the rotation limiting function through the rotating shaft 105b and the limiting sleeve 105c, and are linked with the adjustment component 106; when the cylinder 106a drives the adjustment component 106 to work, the connecting mechanism is driven through the limiting shaft 106b and the sleeve rod 106c, so that the fixing frame 107 and the limiting frame 108 work together to realize the height and angle adjustment of the underframe; the pedal component 109 adapts to different working postures through rotational connection, and the anti-slip strip 109b ensures operation safety.

[0029] The adjustment assembly 106 includes a cylinder 106a, a limiting shaft 106b rotatably mounted at the bottom of the cylinder 106a, and a sleeve rod 106c sleeved on the outer surface of the limiting shaft 106b.

[0030] The adjustment assembly 106 also includes a connecting plate 106d fixedly installed on the outer surface of the sleeve rod 106c, and a connecting rod 106e fixedly connected to the side surface of the connecting plate 106d.

[0031] The pedal assembly 109 includes a pedal 109a, an anti-slip strip 109b fixedly connected to the surface of the pedal 109a, and a mounting plate 109c fixedly installed on the side surface of the pedal 109a.

[0032] The pedal assembly 109 also includes a rotating shaft 109d rotatably mounted on the side surface of the mounting plate 109c, and a connecting sleeve 109e sleeved on the outer surface of the rotating shaft 109d.

[0033] It should be noted that when cylinder 106a drives adjustment assembly 106, limit shaft 106b drives sleeve rod 106c to extend and retract. At the same time, connecting plate 106d and connecting rod 106e transmit power to fixed frame 107 and limit frame 108 to realize overall height adjustment of the lower frame. The two sets of locking assemblies 105 ensure stability during adjustment through the rotational cooperation of rotating shaft 105b and limit sleeve 105c. The pedal assembly 109 adaptively adjusts the angle through the rotational structure of rotating shaft 109d and connecting sleeve 109e. The anti-slip strip 109b on the surface of pedal 109a provides anti-slip protection, enabling operators to work safely in different working postures.

[0034] In use, the cylinder 106a drives the adjustment assembly 106 to move the limit shaft 106b and the sleeve 106c in precise telescopic motion. The linkage connecting plate 106d and the connecting rod 106e transmit the adjustment force to the fixed frame 107 and the limit frame 108, realizing the hydraulic adjustment of the height and angle of the underframe. Two sets of symmetrically arranged locking assemblies 105 cooperate with the rotation of the shaft 105b and the limit sleeve 105c to provide bidirectional stable support during the adjustment process, ensuring structural rigidity. The pedal assembly 109 automatically adapts to different working angles through the rotation mechanism of the shaft 109d and the connecting sleeve 109e. Combined with the anti-slip strip 109b design of the pedal 109a, a safe and reliable operating platform is formed.

[0035] In summary, the basic frame formed by the fixed plate 101 and the limiting plate 102, combined with the adjustable support structure, significantly improves the ease of installation; the double-clamping component 105 and the adjustment mechanism driven by the cylinder 106a work together to ensure the accuracy of height and angle adjustment and enhance the stability of the overall structure; the rotating foot pedal component 109, with its anti-slip design, effectively improves operational safety; the entire system achieves multiple advantages such as easy installation, flexible adjustment, stable operation, and reliable safety through the optimized combination of various components, greatly improving the performance and maintenance convenience of the excavator underframe.
