The width of the driving groove 113 arranged on the side wall of the first cylinder 110 is larger than that of the driving rods 420, limiting blocks 421 are fixedly arranged at the upper end of each driving rod 420, the width of each limiting block 421 is consistent with that of each driving groove 113, and the limiting rings 510 can prevent the driving rods 420 from being separated from the driving grooves 113.
In this embodiment, a rough surface is provided on the side wall of each clamping arc plate 330 near the axis of the second cylinder 210, so as to ensure that the clamping arc plates 330 can clamp the sample block.
In combination with the above embodiments, the working process of the thickness detection device for road engineering construction provided by the embodiment of the present application is as follows:
during operation, the support is moved to the position to be sampled of the pavement 600, the driving motor and the driving air cylinder are started, the driving motor drives the first cylinder 110 to rotate, the extension of the driving air cylinder pushes the driving plate to gradually move downwards, when the first cylinder 110 rotates and moves downwards, the second cylinder 210 synchronously rotates and moves downwards, then the drill bit 220 arranged at the lower end of the second cylinder 210 gradually drills on the pavement 600, and when the drill bit 220 arranged at the lower end of the second cylinder 210 contacts the pavement 600, the friction disc 440 simultaneously contacts the pavement 600.
With the downward movement of the second cylinder 210, the stop ring 410 and the friction disc 440 are always abutted against the road surface 600, the distance between the lower end of the first cylinder 110 and the stop ring 410 is gradually reduced, the stop block 421 on the driving rod 420 gradually slides in the driving groove 113, at this time, the stop ring 410 and the first cylinder 110 synchronously rotate, the second spring 430 is gradually extruded and deformed, the driving disc 310 in the mounting cavity 111 has a tendency to move upwards, and the plurality of clamping arc plates 330 connected to the driving disc 310 also have a tendency to move upwards. Since the first protrusion 331 of each clamping arc plate 330 is located in the first groove 212 on the inner side wall of the second cylinder 210 at this time, and the first spring 312 driving the clamping arc plates 330 to be far away from the axis of the first cylinder 110 is disposed in the sliding groove 311 of the driving disc 310, the edges of the first groove 212 and the first protrusion 331 are chamfered, so that under the restoring force of the second spring 430, the first protrusion 331 of each clamping arc plate 330 always has a tendency to separate from the first groove 212, so that the plurality of clamping arc plates 330 have a tendency to clamp inwards, but at this time, the drill 220 at the lower end of the second cylinder 210 does not drill through the road surface 600, so that the drill 220 at the lower end of the second cylinder 210 does not contact the ground 700, so that the sample block does not separate from the road surface 600, and one side wall of the clamping arc plates 330 close to the axis of the first cylinder 110 is a rough surface, so that the driving disc 310 cannot move upwards in the mounting cavity 111.
As the drill bit 220 at the lower end of the second cylinder 210 drills through the pavement 600, the sample block is disconnected from the pavement 600, the drill bit 220 at the lower end of the second cylinder 210 contacts the ground 700, the compression deformation amount of the second spring 430 is in the maximum state, the restoring force of the second spring 430 pushes the driving disc 310 to move upwards, the first protrusion 331 on the clamping arc plate 330 moves along the inclined chamfer of the first groove 212, the first spring 312 and the first protrusion 331 are gradually deformed, but the deformation amount of the first spring 312 is larger than the deformation amount of the first protrusion 331, at this time, the plurality of clamping arc plates 330 are tightly clamped on the peripheral wall of the sample block, in the process of moving the driving disc 310 upwards, the sample block synchronously moves upwards until the upper end face of the driving disc 310 is abutted against the lower end of the adjusting rod 120, at this time, the first protrusion 331 on the clamping arc plate 330 is also in the state of abutting against the inner side wall of the second cylinder 210, at this time, the position data on the clamping arc plate 330 where the upper end face of the sample block is located are read, and the data are recorded. At the instant the drive disk 310 is moved up, the drive motor and drive cylinder are turned off.
Then the adjusting rod 120 is turned, the adjusting rod 120 gradually moves upwards, the driving disc 310 further moves upwards in the mounting cavity 111 until the first protrusions 331 on the clamping arc plates 330 are separated from the inner side walls of the second cylinder 210, under the action of the first springs 312, the clamping arc plates 330 synchronously move along the sliding grooves 311 away from the axis of the driving disc 310, the clamping arc plates 330 do not clamp the sample block, the sample block starts to fall under the action of self gravity, at this time, the second cylinder 210 is not separated from the holes of the drilled holes, impurity fragments on the side walls of the drilled holes do not fall to the bottoms of the holes, and the sample block can completely fall into the holes.
In the process that the driving disc 310 moves upwards in the mounting cavity 111, the air pressure in the mounting cavity 111 above the driving disc 310 is gradually increased, after the sample block falls into the hole, the driving cylinder is started to shorten, the driving cylinder pulls the first cylinder 110 and the second cylinder 210 to move upwards synchronously, at this time, high-pressure air in the mounting cavity 111 above the driving disc 310 pushes the driving disc 310 to slide downwards, the driving disc 310 drives the plurality of clamping arc plates 330 to move downwards synchronously, in the process that the driving disc 310 moves downwards in the mounting cavity 111, the first protrusions 331 on the clamping arc plates 330 are abutted against the inner side walls of the second cylinder 210 again, according to the stiffness coefficient of the first protrusions 331 and the first springs 312, the deformation amount of the first springs 312 is larger than that of the first protrusions 331, meanwhile, the lower ends of the clamping arc plates 330 are flush with the bottom surface when the driving disc 310 starts to move downwards, the plurality of clamping arc plates 330 approach the axis direction of the driving disc 310 again under the pushing of high-pressure air, and the lower ends of the plurality of clamping arc plates 330 are abutted against the upper ends of the sample block. Under the driving of the driving cylinder and the driving of the high-pressure gas, the first protrusion 331 on the clamping arc plate 330 gradually enters the first groove 212, and the lower end of the second cylinder 210 gradually breaks away from the road surface 600, and further, the device gradually returns to the initial state, so that the next sampling detection of the road surface 600 is facilitated.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the application.
