AI Technical Summary
In the existing foundation bearing capacity detection device, the direct connection between the cylinder and the heavy hammer causes impact force transmission, shortening the service life of the cylinder.
The lifting structure is used as the connecting piece between the cylinder and the heavy hammer. The heavy hammer is automatically separated and falls at the top through the top rod to prevent the cylinder from being directly connected to the heavy hammer, and ensure that the heavy hammer moves in a straight line through the guide rod and the guide block.
It extends the service life of the cylinder, avoids the impact force of the heavy hammer to be directly transmitted to the cylinder, and improves the durability of the device.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of foundation detection, and more specifically, to a device for detecting the bearing capacity of a foundation. Background Technique
[0002] Dynamic penetration test is to use a heavy hammer of a certain mass to drive a probe of a certain specification into the foundation soil, and judge the properties and bearing capacity of the foundation soil according to the number of hammer blows required for the probe to penetrate a certain depth into the soil layer. This method is mainly based on the relationship between the penetration resistance and the strength of the foundation soil. The more the number of hammer blows, the greater the resistance of the foundation soil, and the higher the bearing capacity may be.
[0003] However, the existing dynamic penetration test device for detecting the bearing capacity of a foundation often directly drives the heavy hammer to strike through a cylinder. When the heavy hammer strikes, a large impact force will be generated, and when the impact force is transmitted to the cylinder, it will shorten the service life of the cylinder. In view of this, we propose a device for detecting the bearing capacity of a foundation. Content of the Utility Model

By setting the lifting structure 3 as a connecting member between the cylinder 2 and the heavy hammer 4, the top rod 101 enables the heavy hammer 4 to automatically separate and fall at the top end, without the need for the cylinder 2 to be connected to the heavy hammer 4. The present utility model can use the lifting structure 3 as a connecting member, so that the cylinder 2 does not need to be directly connected to the heavy hammer 4, avoiding the impact force of the heavy hammer 4 from being transmitted to the cylinder 2 and extending the service life of the cylinder 2.

[0024] Working principle: This embodiment provides a device for detecting the bearing capacity of the foundation. During use, the cylinder 2 drives the mounting frame 301 to move downward. The mounting frame 301 drives the boom 302 to move to the hanging block 401. The boom 302 opens through the inclined surface 305 of the buckle 304, so that the buckle 304 is inserted into the buckle groove 402 to connect the boom 302 and the hanging block 401. The cylinder 2 drives the heavy hammer 4 to move upward through the hanging block 401. When the boom 302 moves to the top, the boom 302 contacts the ejector rod 101. The ejector rod 101 squeezes the head end of the boom 302, causing the boom 302 to rotate. Through the arc surface 307, the convex strip 306 is disengaged from the groove 403, opening the boom 302, allowing the heavy hammer 4 to fall freely. The heavy hammer 4 slides on the guide rod 501 through the guide block 5 and impacts the ground to detect the bearing capacity of the foundation.
