[0002] A guide frame is a device used to guide or position the test equipment to ensure that it can work accurately and stably during high-strain testing. In high-strain testing, the guide frame is usually used in conjunction with the test equipment weight to ensure the accuracy and reliability of the test. The guide frame has sufficient strength and stability to withstand the shock and vibration generated during the test. It is widely used in various fields that need to evaluate the performance of materials or structures under high-strain conditions, such as civil engineering, mechanical engineering, aerospace, etc. In these fields, guide frames for high-strain testing can be used to evaluate the load-bearing capacity and safety of structures such as bridges, buildings, aircraft, and vehicles under extreme conditions.

During testing, the flip guide frame can be flipped and combined with the fixed support frame, and both the flip guide frame and the fixed support frame are rigid structures, so that the overall structural stability of the high-strain pile measurement guide frame is high and can meet the need of supporting a heavy hammer, and when the test is completed, the flip guide frame can be flipped to separate the flip guide frame from the fixed support frame, thereby reducing the overall height of the high-strain pile measurement guide frame, which is beneficial to the transportation, transfer and storage of the high-strain pile measurement guide frame."

[0016] 1. The utility model is equipped with an anti-shake mechanism to limit the position of the gravity hammer, so as to prevent the gravity hammer from swinging left and right and causing collision with the guide frame body.

First, the electric pole is limited to drive the positioning block to move, so that the positioning block is in close contact with the outer wall of the weight hammer. Then, when the gravity hammer is moving, the moving slider moves on the moving rod, which drives the moving plate to move. The moving plate drives the hardness box to move, which drives the positioning block to move with the gravity hammer. The gravity hammer can be well limited, so as to avoid damage to the guide frame body caused by the left and right swinging of the weight hammer.

[0017] 2. The utility model is equipped with a lighting mechanism, which makes it easy to watch the travel track of the gravity hammer at night. At night, due to the dim light, the staff cannot clearly see the travel path of the gravity hammer, so it is necessary to improve this. When there is sufficient sunlight, the solar power generation panel is used to convert light energy into electrical energy and store it in the power storage box. When the power inside the power storage box is used up and there is insufficient sunlight, the external charging device can be inserted into the wiring terminal to supplement the power of the power storage box. The lighting panel is moved to the bottom of the mounting plate, and then the locking screw is fixed to the locking screw groove, and then the LED lighting lamp is used to illuminate it, so that the staff can observe the gravity hammer well in insufficient light.
