Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a deformation testing device for the dynamic compaction process of glacial till. Background Technology
[0002] Glacial till, a special geological deposit widely distributed in southeastern Tibet, exhibits characteristics of looseness, low density, and poor stability due to its extremely poor particle size distribution and significant variations in physical and mechanical properties. This poses a great risk to engineering construction. Constructing engineering facilities on glacial till deposits requires effective reinforcement methods to ensure sufficient bearing capacity and stability to avoid disasters such as landslides. Therefore, studying the macroscopic and microscopic mechanical properties of glacial till and its compaction methods, especially deformation detection for strengthening glacial till foundations using dynamic compaction, has significant scientific and engineering application value. Deformation detection devices are required for the testing experiments.
[0003] However, existing technologies have some problems: existing deformation detection devices measure the depressions formed on the surface of glacial till after dynamic compaction using a rangefinder, and then process the collected data through a connected computer. However, existing deformation detection devices only move the rangefinder to a certain position above the depression, and their measurement range is small, often making it difficult to obtain sufficient data, thus reducing the detection accuracy. If more data is needed, multiple measurements are required, resulting in low work efficiency. Therefore, we propose a deformation detection device for the dynamic compaction process of glacial till. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a deformation detection device for the dynamic compaction process of glacial till. Through a pendulum and drive assembly, it can acquire more data at once, thereby improving detection accuracy and work efficiency.
[0005] The purpose of this utility model is achieved as follows: a deformation detection device for dynamic compaction of glacial till includes a base, a guide rail fixedly installed on the top of the base, an electric slide slidably connected on the guide rail, a top plate fixedly connected to the top of the electric slide, a crossbar provided on the top plate, the crossbar and the top plate being connected by a drive assembly, the drive assembly being able to adjust the position and angle of the crossbar, a rangefinder provided on the crossbar, the rangefinder and the crossbar being connected by an adjustment assembly for adjusting the distance between the rangefinder and the crossbar.
[0006] Optionally, the drive assembly includes an electric actuator, which is fixedly mounted on the top plate. A round rod is fixedly mounted on the telescopic end of the electric actuator, and the crossbar is rotatably connected to the round rod.
[0007] Optionally, an arc-shaped hole is provided on the top plate, and a circular block located inside the arc-shaped hole is fixedly installed at the bottom of the crossbar, and the circular block is slidably connected inside the arc-shaped hole.
[0008] Optionally, the diameter of the circular block is adapted to the width of the arc-shaped hole, and the inner wall of the arc-shaped hole is coated with a lubricating layer.
[0009] Optionally, the adjustment assembly includes a slide rod that is movably inserted into a crossbar, a rangefinder that is fixedly connected to the slide rod, a top groove on the top of the slide rod, a pin that is movably inserted into the crossbar, one end of the pin extending into the top groove, and a pull handle that is fixedly connected to the other end of the pin.
[0010] Optionally, a spring is movably sleeved on the outer surface of the pin, and the two ends of the spring are respectively fixedly connected to the crossbar and the pull handle.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This invention, by setting up a crossbar and a drive assembly, allows workers to create depressions in the moraine soil inside the test chamber using a dynamic compaction device. The workers then use an electric slide to move the crossbar and rangefinder above the depression. The position of the rangefinder can be adjusted using an adjustment assembly based on the depression size. Subsequently, the drive assembly causes the crossbar to move the rangefinder, thus adjusting its position and allowing it to swing. This enables the rangefinder to detect different locations within the depression, improving the detection range and work efficiency, and ultimately acquiring more data to enhance measurement accuracy.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figures 1 to 5 As shown in the figure, the present invention provides a deformation detection device for dynamic compaction of glacial till, including a base 1, a guide rail 2 fixedly installed on the top of the base 1, an electric slide 3 slidably connected on the guide rail 2, a top plate 4 fixedly connected to the top of the electric slide 3, a crossbar 5 provided on the top plate 4, the crossbar 5 and the top plate 4 being connected by a drive assembly, the drive assembly being able to adjust the position and angle of the crossbar 5, a rangefinder 6 provided on the crossbar 5, the rangefinder 6 and the crossbar 5 being connected by an adjustment assembly, used to adjust the distance between the rangefinder 6 and the crossbar 5.
[0022] When the rangefinder 6 measures the depressions on the moraine after dynamic compaction, the staff can use the drive component to make the crossbar 5 move the rangefinder 6, thereby adjusting the position of the rangefinder 6 and making the rangefinder 6 swing. This allows the rangefinder 6 to detect different positions inside the depression, increasing the detection range and thus obtaining more data to improve measurement accuracy.
[0023] Furthermore, the drive assembly includes an electric actuator 7, which is fixedly mounted on the top plate 4. A round rod 8 is fixedly mounted on the telescopic end of the electric actuator 7, and a crossbar 5 is rotatably connected to the round rod 8.
[0024] By activating the electric actuator 7, the horizontal bar 5 can be moved by pushing and pulling the round rod 8, which in turn enables the horizontal bar 5 to move the rangefinder 6 back and forth above the glacial till depression, thereby enabling measurement of different positions of the depression after dynamic compaction and improving the measurement range.
[0025] Furthermore, an arc-shaped hole 9 is provided on the top plate 4, and a round block 10 located inside the arc-shaped hole 9 is fixedly installed at the bottom of the crossbar 5. The round block 10 is slidably connected inside the arc-shaped hole 9.
[0026] When the electric actuator 7 drives the crossbar 5 to move, it can drive the circular block 10 to move together, so that the circular block 10 slides along the inside of the arc-shaped hole 9. In turn, the crossbar 5 can rotate around the circular rod 8 under the action of the circular block 10, so that the rangefinder 6 can swing left and right, thereby further improving the measurement range of the depression and acquiring more data to improve the detection accuracy.
[0027] Furthermore, the diameter of the circular block 10 is matched with the width of the arc-shaped hole 9, and the inner wall of the arc-shaped hole 9 is coated with a lubricating layer.
[0028] By coating the inner wall of the arc-shaped hole 9 with a lubricating layer, the circular block 10 can slide more smoothly inside the arc-shaped hole 9.
[0029] Furthermore, the adjustment assembly includes a slide bar 11, which is movably inserted into the crossbar 5. The rangefinder 6 is fixedly connected to the slide bar 11. A top groove 12 is provided at the top of the slide bar 11. A pin 13 is movably inserted into the crossbar 5. One end of the pin 13 extends into the top groove 12, and the other end of the pin 13 is fixedly connected to a pull handle 14.
[0030] By pulling the handle 14, the pin 13 is pulled out from the top groove 12, thus releasing the limit on the slide rod 11. This allows the position of the slide rod 11 to be adjusted, thereby adjusting the distance between the rangefinder 6 and the crossbar 5, which facilitates the detection of dynamic compaction depressions of different sizes.
[0031] Furthermore, a spring 15 is movably sleeved on the outer surface of the pin 13, and the two ends of the spring 15 are respectively fixedly connected to the crossbar 5 and the handle 14.
[0032] By setting the spring 15 to a stretched state, the spring 15's elasticity will cause the pin 13 to tend to move downwards, thus ensuring that one end of the pin 13 is stably held inside the top groove 12, thereby stably maintaining the limiting effect on the slide rod 11 and the rangefinder 6.
[0033] Working principle and usage process of this utility model:
[0034] First, workers use a dynamic compaction device to create indentations in the moraine soil within the box. Then, an electric slide 3 moves the crossbar 5 and the rangefinder 6 above the indentation. If the indentation is large, workers can pull the handle 14 to move the pin 13 upwards and pull it out from inside the top groove 12. Next, the slide bar 11 is moved to adjust the distance between the rangefinder 6 and the crossbar 5 before being locked. Then, the rangefinder 6 and the electric actuator 7 are activated, and the rangefinder 6 measures the indentation depth, which is then exported to an external computer. The data, along with the operation of the electric actuator 7, will cause the round rod 8 to drive the crossbar 5 and the rangefinder 6 to move, enabling measurement of different positions of the depression. At the same time, the crossbar 5 can drive the round block 10 to move together, so that the round block 10 slides along the inside of the arc hole 9, and the crossbar 5 can rotate around the round rod 8 under the action of the round block 10. This will cause the rangefinder 6 to swing left and right, further improving the measurement range of the depression, thereby obtaining more data to improve the detection accuracy.
[0035] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
