Description

Technical Field

[0001] The invention belongs to an action mechanism of an excavator manipulator, and in particular relates to a side-clamping hydraulic vibration hammer installed on a manipulator of an excavator. Background Art

[0002] At present, the manipulator hydraulic vibratory hammer can only rotate 180° left and right during pile driving. If the angle is turned to a certain degree and it is found to be unsuitable, it must rotate back. It cannot rotate 360° according to the working conditions, which is troublesome to operate, and can only pile vertically. In addition, the construction work surface is limited by height, and the height limit cannot be maximized. This type of vibratory hammer has a simple structure, and most of them are currently using this type of vibratory hammer. This hydraulic vibratory hammer is equipped with a clamp under the vibration box, which can clamp one end of the steel sheet pile, stand up the entire steel sheet, start the hydraulic motor after aligning the position, drive the eccentric block to rotate to generate vibration force, and press the steel sheet pile into the ground. However, the pile clamping method of this vibratory hammer can only be clamped at one end of the steel sheet pile for construction. In certain specific construction environments, such as under bridges and other construction environments with limited height, this type of construction equipment cannot be used for construction. For example, if a steel sheet pile needs to be constructed under a bridge, the length of the steel sheet pile is designed to be 15 meters, but the net height under the bridge is 16 meters. If the usual manipulator vibrator is used for construction, only one end of the steel sheet pile can be clamped. The pile is 15 meters long, plus the height of the vibrator is 2 meters, the height of the main arm and auxiliary arm of the excavator is far more than 15 meters. In order to carry out construction, the steel sheet pile can only be cut into two sections, first drive in an 8-meter one, and then drive in a 7-meter one, and weld them into one in the middle. This construction method solves the problem of being unable to construct, and the construction speed becomes very slow. In the middle, you have to wait for welding, and the clamping pile alignment step has to be performed twice, which is inefficient. At the same time, this vibrator can only be used for the construction of steel sheet piles. For the construction of pipe piles, it is necessary to change the fixture or the vibrator, which increases the construction cost. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a side-clamp hydraulic vibratory hammer, which can rotate 360° without restriction without affecting the normal vibration force, and can also swing while rotating, and is suitable for working conditions during construction with a manipulator hydraulic vibratory hammer; in a construction environment where the height is strictly restricted, the restricted height can be utilized to the maximum extent for piling operations, and the side-clamp structure can be used for construction to improve construction efficiency.
