Bridge pile foundation construction anti-vibration device

Abstract

The invention belongs to the field of bridge pile foundations, and particularly relates to a bridge pile foundation construction anti-vibration device. The device is characterized in that supporting columns are slidably mounted at the tops of sleeve bases on the top of a mounting plate correspondingly, a drilling machine is fixedly mounted at the bottom of a transverse plate at the tops of the twosupporting columns, the bottom of an output shaft of the drilling machine penetrates through the top of the transverse plate and extends to the lower portion of the transverse plate, the bottom of adrill bit penetrates through the top of a steel casing on one side of the mounting plate and extends into the steel casing, a rolling groove is formed in the top of a fixing plate at the top of the steel casing, an arc-shaped plate is detachably mounted at the top of a rolling ball on the inner wall of the bottom of the rolling groove in a rolling mode, and sliding blocks slidably connected with two transverse columns are slidably mounted at the tops of two supporting plates at the top of the mounting plate correspondingly. According to the device, vibration and movement of the drilling machine are buffered and damped through first springs, second springs and buffer springs, vibration in the pile foundation construction process can be prevented, a position of the drill bit is limited through the steel casing, position deviation of the drill bit in the drilling process is prevented, and the precision in the pile foundation drilling process can be effectively improved.

Description

technical field [0001] The invention belongs to the field of bridge pile foundations and relates to an anti-vibration device for bridge pile foundation construction. Background technique [0002] As an important part of the engineering structure, the bridge pile foundation is used to transfer the superstructure load to the rock foundation, and its quality status plays a vital role in ensuring the safe operation of the engineering structure. During the construction of the bridge pile foundation, it is necessary to use a drilling device to drill holes under the ground to lay the foundation for the bridge construction. [0003] The current bridge pile foundation drilling device mainly has the following problems: during the drilling process, the drilling tool will generate serious vibration, which will easily cause the drill bit to tilt when drilling, and affect the drilling accuracy. Therefore, we propose An anti-vibration device for bridge pile foundation construction is used...
