Description

Technical Field

[0001] The utility model relates to the technical field of penetration instruments, in particular to a fully automatic light penetration instrument. Background Art

[0002] In the construction of buildings, municipal engineering, roads and other projects, after the foundation pit is excavated or the roadbed is filled, the foundation bearing capacity needs to be tested to verify whether the foundation geology and bearing capacity meet the design requirements. If the foundation bearing capacity is insufficient, it will cause the foundation to deform, and then cause the structure or road surface to sink. Therefore, the foundation bearing capacity test is an important test procedure in the construction process.

[0003] The light penetration instrument is a tool for testing the bearing capacity of foundation. The light penetration instrument includes a probe rod composed of a probe rod and a heavy hammer. It is an in-situ testing device that uses a certain amount of drop hammer energy to determine the properties of the soil by measuring the difficulty (penetration) of driving a conical probe of a certain size into the soil.

[0004] At present, when a light-duty penetration instrument is used to detect soil layers, the device is usually moved to the location of the soil layer to be probed, and then the staff manually lifts the weight to a certain height and then releases the weight. The weight then falls freely and penetrates into the soil layer for detection. This process requires manual lifting of the weight, which is not only time-consuming and labor-intensive, but also unable to accurately control the lifting frequency and lifting height, resulting in low detection efficiency and poor detection accuracy.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Example 1

[0027] Reference Figure 1 , 2 3 is the first embodiment of the utility model, which provides a fully automatic light-duty feeler, including a right-angle C-shaped seat 1, a tooth plate 2 is slidably inserted on the top of the right-angle C-shaped seat 1, a driving assembly is provided between the tooth plate 2 and the right-angle C-shaped seat 1, a feeler rod 3 is fixedly connected to the bottom of the tooth plate 2, and a weight 4 is fixedly connected to the bottom of the feeler rod 3;

[0028] The driving assembly includes a moving plate 5 slidably inserted in the side wall of the right-angle C-shaped seat 1, a double-axis motor 6 is fixedly connected to the top of the moving plate 5, and the double-axis motor 6 is placed between the right-angle C-shaped seat 1 and the gear plate 2, and the two output shaft ends of the double-axis motor 6 are fixedly connected to gears 7, and the two gears 7 are meshed with the gear plate 2;

[0029] Specifically, the side wall of the tooth plate 2 is fixedly connected to the limit block 14, and the limit block 14 is placed above the right-angle C-shaped seat 1. Four legs 15 are fixedly installed at the bottom of the right-angle C-shaped seat 1, and the four legs 15 are respectively placed at the four corners of the bottom of the right-angle C-shaped seat 1. The side wall of the right-angle C-shaped seat 1 is provided with a notch 16, and the feeler rod 3 is slidably arranged in the notch 16;

[0030] Furthermore, starting the dual-axis motor 6 can drive the two gears 7 to rotate counterclockwise synchronously, and then drive the toothed plate 2 meshing therewith to move upward, that is, drive the weight 4 to move upward synchronously through the feeler rod 3 until the weight 4 moves to a specified height.

[0031] Example 2

[0032] Reference Figure 1 , 2 3 is the second embodiment of the utility model, which is based on the previous embodiment, and the tooth plate 2 is further provided with an intermittent control component;

[0033] The intermittent control assembly includes a fixed plate 8 fixedly connected to the bottom of the moving plate 5, a magnetic block 10 is fixedly connected to one side of the fixed plate 8 close to the right-angle C-shaped seat 1, and a spring 9 is commonly connected between the fixed plate 8 and the right-angle C-shaped seat 1, an electromagnet 11 is fixedly connected to the inner side of the right-angle C-shaped seat 1, and the electromagnet 11 is attracted to the magnetic block 10 when energized, a pressing block 12 is fixedly connected to the side wall of the tooth plate 2, and a push-type switch 13 is fixedly installed on the inner top wall of the right-angle C-shaped seat 1, and the push-type switch 13 is electrically connected to the electromagnet 11;

[0034] Specifically, a through hole is opened at the top of the right-angle C-shaped seat 1, and the through hole is slidably connected to the tooth plate 2, the pressing block 12 and the push-type switch 13 are on the same vertical line, and the pressing block 12 is located on the toothless side of the tooth plate 2;

[0035] Further, when the tooth plate 2 drives the pressing block 12 to move upward, when the pressing block 12 contacts and presses the pressing switch 13, the electromagnet 11 is energized, attracting the magnetic block 10 to pull the moving plate 5 to move leftward through the fixed plate 8, and compressing the spring 9 until both gears 7 are separated from the tooth plate 2. At this time, under the overall gravity of the tooth plate 2, the feeler rod 3 and the weight 4, the weight 4 moves downward and starts to hammer the soil layer to be detected;

[0036] Working principle: When in use, the device is carried to the soil layer to be detected, and then the external power supply of the device is turned on, and the dual-axis motor 6 is started to drive the two gears 7 to rotate synchronously counterclockwise, and then the toothed plate 2 meshing with it is driven to move upward, that is, the weight 4 is driven to move upward synchronously through the feeler rod 3 until the weight 4 moves to the specified height. At the same time, when the pressing block 12 contacts the push switch 13 and presses the push switch 13, the electromagnet 11 is energized, and the magnetic block 10 is attracted to pull the moving plate 5 to move to the left through the fixed plate 8, and the spring 9 is compressed until the two gears 7 are disengaged from the toothed plate 2. At this time, the toothed plate 2, the feeler rod 3 and the weight 4 are integrally moved. Under the action of gravity, the heavy hammer 4 falls freely and starts to hammer the soil layer to be detected. Then, when the tooth plate 2 falls freely and causes the heavy hammer 4 to hammer the soil layer, the pressing block 12 starts to stop pressing the push switch 13, so that the electromagnet 11 is powered off and no longer attracts the magnetic block 10, and the spring 9 can push the fixed plate 8 away until the two gears 7 are meshed with the tooth plate 2 again. By repeating the above steps, the heavy hammer 4 can be automatically raised and lowered in a cycle, that is, there is no need to manually lift and lower the heavy hammer 4, and the lifting frequency and lifting height of the heavy hammer can be accurately controlled, thereby improving the detection efficiency and detection accuracy.
