Description

Technical Field

[0001] The utility model relates to the technical field of probe machines, in particular to a probe machine for engineering supervision. Background Art

[0002] The drilling machine is an ideal electric machine for testing the foundation of building construction. It can judge the hardness of the foundation according to the number of hammer drops corresponding to the same distance the probe rod descends.

[0003] A Chinese patent discloses a drilling machine for engineering supervision, with the publication number CN216194624U, comprising: a main body, a drilling assembly, an auxiliary fixing assembly and a driving assembly; the drilling assembly is installed on the top of the main body, and the drilling assembly and the main body are interconnected; the auxiliary fixing assembly is installed on the bottom of one side of the main body, and the auxiliary fixing assembly and the main body are interconnected. The utility model is provided with a drilling assembly, which can help the operator to perform drilling during use, and can also improve the stability of the drilling head falling during the drilling process, thereby making it more convenient for the operator to perform drilling, and the utility model is provided with an auxiliary fixing assembly, which can be used to assist the device from both sides during the use of the device, so that the device is placed more stably, and the device is prevented from tilting or tipping over, thereby increasing the stability of the device during use.

[0004] However, it still has the following disadvantages: the device uses a servo motor to drive the rotating rod to rotate, so that the rope lifts the probe rod and makes the probe rod go deep into the ground. However, when the probe rod falls down, it is difficult to keep it vertical and it is difficult to fall on a point multiple times, which affects the judgment of the foundation hardness. Therefore, we propose a probe machine for engineering supervision to solve this problem. Utility Model Content
