Description

Technical Field

[0001] The present invention belongs to the technical field of municipal road detection, and specifically refers to a municipal road detection device. Background Art

[0002] In current municipal road construction and maintenance work, road strength detection is a key link to ensure road quality and safety. At present, the detection of municipal road strength mainly relies on electronic devices and complex testing systems to carry out work. For example, devices such as pressure sensors and strain gauges are often used, and special data acquisition and analysis software is required to measure various indicators closely related to strength such as the bearing capacity of the road.

[0003] However, these detection systems based on electronic technology are not perfect. They have a series of problems. First, the cost is high, including both the equipment purchase cost and the subsequent use and upgrade costs. Second, the electronic detection system is very vulnerable to environmental factors. Invisible factors such as electromagnetic interference will have a greater impact on the detection results; a humid environment will also damage the performance of electronic components, thus affecting the accuracy and stability of the entire detection system. In addition, the maintenance of these electronic devices is very complicated and requires professional technical personnel and a specific maintenance environment, which undoubtedly increases the labor and material costs.

[0004] In view of the above situations, it is particularly important to develop a device for detecting the strength of municipal roads without any electronic sensing elements. If such a device can be successfully developed and put into use, it is expected to overcome many disadvantages of the electronic detection system and provide a more reliable, economical, and easy-to-maintain solution for the detection of municipal road strength.

Near the turning handle 31 on the detection vehicle 1, there is a telescopic clamping column 32.

[0026] During specific use, move the inspection vehicle 1 to the municipal road to be inspected. Rotate the movable plate 45, slip the canvas roll 46 onto the sleeve shaft 44, then rotate the movable plate 45 to limit the canvas roll 46, and pull the canvas to the winding column 42 for fixation. Push the telescopic clamping column 32 away from the rotary handle 31.

Under the action of the spring 16, the strengthening weight 11 will be more stable, achieving the technical effect of detecting the road strength under different stresses. When inspecting the next road surface, rotate the rotary handle 31. The rotation of the rotary handle 31 drives the winding wheel 30 to rotate. The rotation of the winding wheel 30 drives the pull rope 29 to rotate. The rotation of the pull rope 29 drives the inspection hammer block 8 to move upward along the hammering limit guide frame 7. After moving up to the specified height, pull out the telescopic clamping column 32 to lock the rotary handle 31. Push the handrail plate 51 to move the inspection vehicle 1. The movement of the inspection vehicle 1 drives the rear axle 49 to rotate. The rotation of the rear axle 49 drives the driving wheel 38 to rotate.

The rotation of the meshing wheel 41 drives the winding column 42 to rotate. The rotation of the winding column 42 drives the canvas to wind up, achieving the technical effect of real-time replacement of the canvas. The above is the specific working process of the present invention. Just repeat these steps during the next use.
