AI Technical Summary

Technical Problem

The existing technology lacks a method to effectively verify the control system during the pile hammer design stage, resulting in a large error between the hammer's striking energy and the required energy when it is actually put into use, and the modification cost is high.

Method used

During the pile hammer design stage, a test device is made, a simulated hammer core and sensor block are used, the distance between the sensor blocks is adjusted, and encoder measurements are combined to verify whether the lifting displacement and striking energy of the control system meet the design requirements.

Benefits of technology

The test process is simplified, the cost is reduced, the position of the sensing block can be adjusted in advance during the design phase, ensuring that the control system meets the design requirements before being put into use, and improving the measurement accuracy and adjustment efficiency.

Abstract

A test method for debugging and verifying a pile hammer control system, which uses a test device with the same lifting device, electric control device and sensor assembly as the pile hammer, and the test device further comprises a simulated hammer core with the same weight as the hammer body of the pile hammer, compared with the prior art which uses an actual production pile hammer prototype for testing, the test cost can be reduced, the design and installation distance of adjacent sensing blocks can be given in advance through the lifting test in the control system design process of the pile hammer, and whether the control system meets the design requirements can be verified in advance through the hitting simulation test before the actual operation of the pile hammer, the comparison is carried out through sensing block measurement and encoder measurement, the measurement accuracy of the encoder is higher than that of the sensing block measurement method actually used on the pile hammer, the case that the pile hammer control system using the sensing block measurement method does not meet the design requirements can be accurately tested, and the control system can be adjusted according to the experimental results before the pile hammer is actually put into production.
