Problems solved by technology

[0003] The existing hydraulic pile drivers generally have the following technical disadvantages: (1) When the main engine of the excavator is equipped with a pile driver, the working mode of controlling the pile driver is complicated, and the hydraulic pipeline is messy; (2) There will be piles when driving or pulling piles; (3) When carrying out piling construction on hard ground or pulling out piles with large frictional resistance, the exciting force of the pile driver is insufficient, which cannot meet the requirements for pile driving

Embodiment 1

[0042] Please refer to Figure 1~3 , the present embodiment discloses a secondary vibration system 100 of a pile driver. The secondary vibration system 100 of a pile driver includes a mode selector 110, an oil supply module, a first pressure sensor 131 and a control module, reducing the complexity of hydraulic pipeline layout To a certain extent, the excitation force of the pile driver is enhanced by the secondary vibration, the piling speed is increased and the fuel consumption is reduced.

[0043] The mode selector 110 is used to acquire the selection result of the vibration mode by the user. Specifically, the mode selector 110 is an input terminal for the user to input a selection instruction, so as to realize manual switching between the primary vibration mode and the secondary vibration mode.

[0044] There are many ways to implement the input terminal. Exemplarily, the mode selector 110 is a mechanical button, a mechanical gear switch or a touch screen. For example, th...

Embodiment 2

[0063] This embodiment also discloses a secondary vibration control method of a pile driver, which is applied to the secondary vibration system 100 of a pile driver disclosed in Embodiment 1, including the following steps:

[0064] Step A: Obtain the selection result of the vibration mode by the user, and the selection result is primary vibration or secondary vibration;

[0065] Step B: obtaining the working pressure of the first main pump 121;

[0066] Step C: According to the selection result of the user and / or the working pressure of the first main pump 121 , switch control between the primary vibration mode and the secondary vibration mode is realized.

[0067] Exemplarily, the method for controlling the secondary vibration of the pile driver further includes the following steps:

[0068] Step C1: Obtain the current vibration mode of the hydraulic vibration motor;

[0069] Step C2: If the hydraulic vibration motor is in the primary vibration mode and the working pressure...

Abstract

The invention discloses a secondary vibration system of a pile driver and a control method thereof. The vibration system includes: a mode selector for obtaining the selection result of the vibration mode by the user; an oil supply module including a first main pump and a second main pump , in the primary vibration mode, the pressure oil of the hydraulic vibration motor is only supplied by the first main pump; in the secondary vibration mode, the pressure oil of the hydraulic vibration motor is supplied by the first main pump and the second main pump together, the hydraulic vibration The motor is used to generate the excitation force; the first pressure sensor is used to obtain the working pressure of the first main pump; the control module has a controller electrically connected to the first pressure sensor, and is used to select the result according to the user and / or The working pressure of the first main pump realizes switching control between the primary vibration mode and the secondary vibration mode. The secondary vibration system and control method of the pile driver reduce the complexity of hydraulic pipeline layout, enhance the exciting force of the pile driver with secondary vibration, increase the pile driving speed and reduce fuel consumption.

Description

technical field [0001] The invention belongs to the technical field of pile drivers, in particular to a secondary vibration system and control method of pile drivers. Background technique [0002] The hydraulic pile driver is a very commonly used excavator attachment, which can carry out various pile construction operations such as steel pipe piles, steel sheet piles, and special-shaped piles. The working principle of the hydraulic pile driver is to use the hydraulic drive of the excavator to obtain power, generate high-frequency vibration to achieve a short-term liquefaction effect on the soil around the pile body, reduce the frictional resistance of the pile body, and drive the pile body smoothly into or out, with vibration High efficiency, simple operation, quick installation and so on. [0003] The existing hydraulic pile drivers generally have the following technical disadvantages: (1) When the main engine of the excavator is equipped with a pile driver, the working mo...
