Problems solved by technology
This device has a big disadvantage. Under the rotation of the three-phase asynchronous motor, the three directional wheels cannot make a circular motion along a complete circle, which leads to the instability of the whole device.
Since the device is doing a circular motion, the data we need cannot be accurately measured

[0046] As the first embodiment of the present invention, the continuous load detection experiment still uses the weight as the actuator. The difference is that in this type of test, the weight mechanism is driven by the first horizontal module and the second horizontal module. Make horizontal movement, change the continuous pressure of the hammer on the ground by changing the extension length of the hydraulic cylinder, and monitor the cracks of the roadbed in real time through the radar installed at both ends of the platform.
[0047] A linear guide rail 8 is installed on the multifunctional platform 1, a slide block 9 is arranged on the linear guide rail 8, an adapter plate 10 is placed on the slide block 9, and a first horizontal module 16 and a second horizontal module 17 are installed on the bottom of the adapter plate 10, and turn Swimming support 18 is installed between connecting plate 10, and first pressurization module 12 and second pressurization module 13 are arrange...

The utility model relates to a multifunctional road cycle load detection machine, which belongs to the technical field of road detection. During operation, the bionic foot uses the wire cylinder to pull the upper limb mechanism and the lower limb mechanism to swing alternately to realize the rapid progress of the whole set of equipment. The working principle of the wire cylinder is to install the wire cylinder between the fixed bracket and the actuator through the wire rope, and install the shuttle in the cylinder of the wire cylinder. The two ends of the wire rope on the wire roller are respectively wound on the horizontally installed reversing wheel and the vertically installed reversing wheel and form a wire rope loop with the wire roller body. After power on, the motor installed in the cylinder drives the wire When the roller rotates, when the motor rotates in the forward direction, the wire roller performs the forward wire take-up operation, and the overall length of the wire cylinder becomes smaller, which drives the actuator to swing upwards. Conversely, when the motor rotates in the reverse direction, the wire roller performs the reverse wire take-up operation. , the overall length of the wire cylinder becomes longer, the actuator swings downward under the action of gravity, and the continuous and alternating movements of the upper and lower limbs can realize the rapid travel of the whole machine.
Description
technical field [0001] The invention relates to the technical field of road detection, in particular to a multifunctional road cycle load detection machine. Background technique [0002] Scholars have done a lot of research on the detection of recessive pavement diseases, and at the same time proposed many detection methods. The early empirical method was judged by subjective on-site observation, and later developed into a mechanical response detection method represented by FWD, using more advanced Instruments and methods, such as ultrasonic testing instruments, etc., such as a ground penetrating radar mentioned in Patent No. 201720804169.1, its main structure is to install the transmitting antenna and receiving antenna on the trolley, and transmit high-frequency electromagnetic waves underground through the transmitting antenna. When propagating in the underground medium, reflection occurs when encountering an interface with electrical differences, and the spatial position,...
