Electromagnetic drop hammer piling tester with accurate and controllable drop distance
The invention discloses an electromagnetic drop hammer piling tester with an accurate and controllable drop distance. The piling tester comprises a movable frame, a longitudinal guide rail, a transverse guide rail, a movable bracket, a connecting rod, a transverse lead screw, a lead screw lifter, a vertical lead screw, an electromagnetic chuck, a heavy hammer and a guide centralizer. According to the piling tester, the electromagnetic chuck is controlled by an electric control box to automatically finish grabbing and lifting of a pile hammer and releasing of the pile hammer, and manual operation is not needed; and meanwhile, the lead screw lifter is controlled by the electric control box to finish up-down movement of the pile hammer. The weight of the pile hammer can be adjusted by adding a counter weight, and the lifting height can be randomly adjusted in a travel range. The tester is used for carrying out a model test so that the accuracy of a test result can be greatly improved. The piling tester is provided with a pile pipe centralizer and a pile pipe does not need to be pre-buried; the pile hammer moves up and down in the centralizer so that potential safety hazards caused by the fact that the pile hammer is released in a piling process are avoided; and the pile pipe centralizer is used for effectively improving the safety in a testing process.
本发明公开了一种落距精准可控的电磁落锤打桩试验机，该打桩试验机包括可移动框架、纵向导轨、横向导轨、移动支架、连接杆、横向丝杠、丝杠升降机、竖向丝杠、电磁吸盘、重锤和导向扶正器。该打桩试验机桩锤抓取上提和桩锤的释放通过电控箱控制电磁吸盘自动完成，不需要手动操作，同时桩锤上下移动也由电控箱控制丝杠升降机完成。桩锤可通过增加配重来进行重量调节，起升高度在行程范围内可任意调节。使用该试验机进行模型试验可以大大提高试验结果的精确度。该打桩试验机设置有桩管扶正器，桩管无需预埋，桩锤在扶正器中上下移动避免打桩过程中脱出造成安全隐患，桩管扶正器有效提高了试验过程中的安全性。
