Problems solved by technology

[0003] Based on the discovery of the above inventors, the existing hydraulic excavator piling equipment mainly has the following deficiencies, such as: because the piling equipment is connected to the fuselage, when the piling equipment is working, the hydraulic hammer repeatedly hits the top of the pile, The vibration generated by the impact will drive the entire fuselage to shake, causing the position of the fuselage to shift, resulting in a deviation in the position of the hydraulic hammer hitting the pile

Embodiment 1

[0026] Example 1: Please refer to Figure 1-Figure 5 , the specific embodiments of the present invention are as follows:

[0027] Its structure comprises fuselage 1, crawler belt 2, piling equipment 3, and the bottom of described fuselage 1 is provided with crawler belt 2, and described crawler belt 2 is provided with two, and is respectively located at the two ends of fuselage 1, and described piling equipment 3 Installed on the front end of the fuselage 1, the piling device 3 includes a support column 31, a limit seat 32, and a piling device 33. The support column 31 is engaged with the front end of the fuselage 1, and the limit seat 32 is installed on the front end of the fuselage 1. The bottom end of the support column 31 , the piling device 33 is installed on the front end of the support column 31 .

[0028] The piling device 33 includes a mounting seat 331, a hydraulic seat 332, a lifting column 333, a buffer device 334, and an impact device 335. The rear end of the mou...

Embodiment 2

[0032] Example 2: Please refer to Figure 6-Figure 8 , the specific embodiments of the present invention are as follows:

[0033] The impact device 335 includes an impact block b1, an oil return groove b2, an oil baffle b3, and an impact body b4. The interior of the impact block b1 is hollow, and the oil return groove b2 is located at the inner top of the impact block b1. There are two oil baffles b3, which are respectively located at both ends of the oil return groove b2. The impact body b4 is engaged in the middle of the oil return groove b2. The two ends of the oil return groove b2 are arc-shaped and high in height. On the bottom end surface of the oil return groove b2, it is beneficial to allow the hydraulic oil in the oil return groove b2 to flow downward automatically when the impact body b4 is not impacted.

[0034] The oil baffle b3 includes an oil return hole b31, an oil passage b32, and a fixing seat b33. The oil return hole b31 is arranged at the bottom of the oil ...

Abstract

The invention discloses hydraulic excavator piling equipment. The hydraulic excavator piling equipment structurally comprises a machine body, two crawler belts and piling equipment, wherein the two crawler belts are arranged at the bottom of the machine body and are respectively located on both ends of the machine body, the piling equipment is installed on the front end of the machine body, the piling equipment comprises a support column, a limiting seat and a piling device, the piling device comprises a mounting seat, a hydraulic seat, a lifting column, a buffer device and an impact device, the buffer device comprises a buffer block, a hydraulic oil groove, a clamping block, an oil passing groove and a movable block, and the oil passing groove comprises a groove body, an oil outlet, an oil baffle block and a connecting groove. According to the hydraulic excavator piling equipment, hydraulic oil in the hydraulic oil groove can be extruded by virtue of the movable block, so that the hydraulic oil is discharged outwards from the oil passing groove, the movable block can be retracted, the impact device is buffered, the condition that the machine body is deviated due to large vibration is avoided, and a pile can be accurately impacted by the impact device.

Description

technical field [0001] The invention relates to the hydraulic field, in particular to a hydraulic excavator piling equipment. Background technique [0002] The excavator-type pile driver is mainly used for piling of small buildings. It has good flexibility and can work in relatively narrow places. When piling, the sleeve is inserted into the top of the pile, and then the pile is repeatedly driven by a hydraulic hammer. The top end enables the pile to be inserted into the soil. [0003] Based on the discovery of the above inventors, the existing hydraulic excavator piling equipment mainly has the following deficiencies, such as: because the piling equipment is connected to the fuselage, when the piling equipment is working, the hydraulic hammer repeatedly hits the top of the pile, The vibration generated by the impact will drive the entire fuselage to shake, causing the position of the fuselage to shift, resulting in a deviation in the position where the hydraulic hammer hit...
