Description

Technical Field

[0001] The present invention belongs to the technical field of road construction devices, and in particular relates to a cutting device for road construction. Background Art

[0002] Road construction is carried out by workers in conjunction with modern equipment. In order to increase the friction of the road surface or when the road surface is damaged and needs repair, it is necessary to cut the road surface. The road cutting device can assist workers in construction quickly and smoothly.

[0003] Traditional road cutting machines use hand-pushed road cutting machines when cutting roads. The cutting route needs to be marked in advance and then the cutting machine is manually pushed according to the markings to cut the road. This makes it easy for the cutting machine to have position deviations during movement. Especially for inclined roads, it is difficult to control the movement direction of the cutting machine. In the face of complex terrain, it is impossible to adjust the position of the cutting blade in time to make it operate perpendicular to the road surface. In addition, the existing road cutting device generates a lot of noise during operation and it is difficult to clean up the mud and dirt generated during the cutting operation in a timely manner. Summary of the Invention

It can adjust the position of the cutting knife in time according to the inclination of the road, ensure that the cutting knife is perpendicular to the road, avoid damage to the cutting knife, and improve the adaptability of the cutting device to complex terrain; the cutting knife is cooled and dust is reduced by spraying water, and the power motor is water-cooled and shock-absorbing at the same time, which reduces noise and extends the service life of the power motor. In addition, the water mist recovery mechanism is used to clean up the mud and dirt generated during the cutting operation in time and recycle water, thereby improving the work efficiency of the road cutting operation.

When the first rolling ball, the second rolling ball and the pulley touch the ground, if the values of the rangefinders in the first telescopic column, the second telescopic column and the adjustable telescopic column are equal or within the differential threshold, it means that the plane formed by the landing points of the first rolling ball, the second rolling ball and the pulley is relatively parallel to the ground, which can ensure that the cutting knife is perpendicular to the ground when it moves down for cutting, thereby avoiding damage to the cutting knife; the relative angles of the entire shock-absorbing and cooling cutting assembly with the ground in the left-right direction and the front-back direction are adjusted by the first steering motor and the second steering motor respectively, ensuring that the cutting knife is perpendicular to the ground when it moves down, thereby improving the adaptability of the cutting device to complex terrain.

[0050] Working principle and workflow:

[0051] During specific use, the staff arranges the guide mechanism 1 on the road to be cut, and the length of the guide rod 11 is selected to be suitable for the length of the road to be cut. At this time, the adjustable power assembly 3 is suspended between the guide rods 11, and two L-shaped plates are respectively suspended at the connecting plates 13 at both ends of the guide rod 11, connected to the two ends of the guide rod 11, used to close the drive slot 15, and fixed with screws when necessary; then the main controller is started to adjust the telescopic length of the hydraulic telescopic column 31, so that the first ball 216, the second ball 43 and the pulley 53 touch the ground, the compression spring 6 is compressed, and the rangefinder 7 works. Multiple sets of rangefinders 7 measure the first telescopic column 41, the second telescopic column 5 1 and the telescopic length of the adjustable telescopic column 213. When the adjustable telescopic column 213, the first telescopic column 41 and the second telescopic column 51 are fully extended, the lower end surface of the fender 214 is tangent to the cutting knife 212. Therefore, the relative position of the cutting knife 212 and the ground can be determined by the telescopic lengths of the first telescopic column 41, the second telescopic column 51 and the adjustable telescopic column 213. The difference thresholds of multiple sets of rangefinders 7 are set in advance. When the first rolling ball 216, the second rolling ball 43 and the pulley 53 touch the ground, if the values of the rangefinders 7 in the first telescopic column 41, the second telescopic column 51 and the adjustable telescopic column 213 are equal or within the difference threshold, it means that the first rolling ball 216, the second rolling ball 43 and the pulley 53 are on the ground. The plane formed by the landing point of the two balls 43 and the pulley 53 is relatively parallel to the ground, which can ensure that the cutting knife 212 is perpendicular to the ground when it moves down for cutting, thereby avoiding damage to the cutting knife 212; if the difference between the values measured by the rangefinder 7 in the first telescopic column 41 and the second telescopic column 51 is large and the values measured by the rangefinder 7 in the adjustable telescopic column 213 are equal, it means that the cutting knife 212 is tilted forward or backward relative to the ground, at this time the second steering motor 325 is started, the longitudinal rotating column 324 drives the adjusting plate 323 to rotate relative to the fixed plate 326, and the adjusting plate 323 drives the hydraulic telescopic column 31 and the shock-absorbing and cooling cutting assembly 2, the front stop mechanism 4 and the lower portion thereof The water mist recovery mechanism 5 rotates synchronously as a whole, adjusting the overall front-to-back angle until the values measured by the rangefinder 7 in the first telescopic column 41 and the second telescopic column 51 are equal. If the difference in the values measured by the rangefinder 7 in the symmetrical adjustable telescopic column 213 is large, it means that the cutting blade 212 is tilted in the left-right direction relative to the ground. At this time, the first steering motor 322 is activated, and the transverse rotating column 321 drives the hydraulic telescopic column 31 to rotate relative to the adjustment plate 323, adjusting the overall left-right angle of the shock-absorbing and cooling cutting assembly 2, the front stop mechanism 4, and the water mist recovery mechanism 5 until the values measured by the rangefinder 7 in the symmetrical adjustable telescopic column 213 are equal.

[0052] The first steering motor 322 and the second steering motor 325 are used to adjust the relative angles of the shock-absorbing and cooling cutting assembly 2 to the ground in the left-right direction and the front-back direction, respectively, to ensure that the cutting blade 212 is perpendicular to the ground when it moves downward.

[0053] After adjusting the relative position of the cutting blade 212 and the ground, the power motor 232 is started, and the first pump 223 and the second pump 224 are working at the same time. The power motor 232 drives the cutting blade 212 to rotate, and the second pump 224 directly sucks the water in the water tank 221 into the water collecting chamber 218 on one side, while the first pump 223 pumps the water in the water tank 221 into the power cover 231 through the connecting pipe 222. When the power motor 232 is working, it is water-cooled, and the water flowing through the power cover 231 flows to the collecting chamber 218 on the other side through the water pipe. In the water cavity 218, water in the water collecting cavity 218 on both sides of the cutting blade 212 is sprayed out through the water spray port 217, cooling the cutting blade 212 and simultaneously reducing dust. The heat generated by the power motor 232 during operation is conducted away by the flowing water. The clamping plate 233 clamps the power motor 232. The vibration generated by the power motor 232 during operation is offset by the shock-absorbing spring 234. In addition, the noise generated by the power motor 232 during operation is difficult to be transmitted out due to the wrapping of the power cover 231 and the water flow, thereby reducing noise.

[0054] Start the hydraulic telescopic column 31, which pushes the shock-absorbing and temperature-cooling cutting assembly 2 to move downward as a whole, and the adjustable telescopic column 213, the first telescopic column 41 and the second telescopic column 51 shrink, and the pressure spring 6 is compressed. When the shrinkage distance of the adjustable telescopic column 213 is equal to the distance from the lower end cross-section of the first running ball 216 to the lower end surface of the fender 214, that is, the value detected by the rangefinder 7 is equal to its initial value minus the shrinkage amount of the adjustable telescopic column 213 at this time, the cutting knife 212 contacts the road surface, and the hydraulic telescopic column 31 continues to push the cutting knife 212 to cut the road. The cutting depth of the cutting knife 212 can be adjusted by the values detected by the hydraulic telescopic column 31 and the rangefinder 7.

[0055] When the driving motor is started, the rotating shaft 332 drives the toggle plate 333 to rotate. When the toggle plate 333 rotates, it forms an engaged transmission structure with the driving rod 16, thereby causing the driving block 331 to slide in the driving groove 15 and the pressure column 327 to slide in the sliding groove 14. At this time, the cutting knife 212 cuts the road. In this process, the stones or debris on the forward path of the cutting knife 212 are blocked by the front baffle 44 and slide to the outside of the arrow-shaped front baffle 44 to prevent the cutting knife 212 from touching the debris on the ground and causing damage. At the same time, the recovery basket 52 is always close to the ground, and the water mist and mud generated by the cutting of the cutting knife 212 are splashed into the recovery basket 52. Large particles of mud impurities are collected by the miscellaneous cavity 54, and the water mist and the mud are absorbed by the first filter cotton 511 through the mud filter net 57. As the cutting operation proceeds, the first filter cotton 511 absorbs more and more water, and the main The timing control module of the controller starts the conversion motor 59 and the third pump 225 after the power motor 232 has been working for a certain period of time. The conversion motor 59 rotates the conversion threaded column 58, thereby causing the conversion plate 510 to slide in the adsorption chamber 55. The conversion plate 510 slides toward the first filter cotton 511 to squeeze the first filter cotton 511 and squeeze out the water therein. The second filter cotton 512 is unfolded under the drive of the conversion plate 510, and continuously absorbs the water mist splashed by the cutting knife 212. The water squeezed out by the first filter cotton 511 falls into the recovery chamber 56 through the water leakage net 513, and is then pumped into the water tank 221 for recycling through the third pump 225 through the suction pipe 226. The sliding of the conversion plate 510 allows the first filter cotton 511 and the second filter cotton 512 to absorb and drain water in turn, thereby extending the water filling cycle of the water tank 221, increasing the operating time of the cutting knife 212, and improving the efficiency of the road cutting operation.

[0056] If there are multiple slopes within the road range covered by the guide mechanism 1, during the movement of the cutting blade 212, the first running ball 216, the second running ball 43 and the pulley 53 around it are always in contact with the ground under the elastic pressure of the compression spring 6. When a slope appears, the difference between the values detected by the first telescopic column 41, the second telescopic column 51 and the rangefinder 7 in the adjustable telescopic column 213 exceeds the threshold value, and the hydraulic telescopic column 31 contracts immediately, so that the cutting blade 212 is lifted off the ground. According to the above-mentioned adjustment principle, the first steering motor 322 and the second steering motor 325 respectively adjust the relative angles of the shock-absorbing and temperature-reducing cutting assembly 2 to the ground in the left-right direction and the front-back direction, so as to ensure that the cutting blade 212 is perpendicular to the ground when it moves downward before the road cutting operation is carried out, thereby avoiding damage to the cutting blade 212 and improving the adaptability of the cutting device to complex terrain.

[0057] After the road cutting operation is completed, the hydraulic telescopic column 31 retracts and resets, the power motor 232 and the drive motor stop, the first pump 223, the second pump 224, the third pump 225 and the conversion motor 59 stop working, and the staff cleans the mud in the miscellaneous chamber 54 and regularly cleans and replaces the mud filter net 57, the first filter cotton 511 and the second filter cotton 512.

[0058] It is worth noting that the water tank 221 is made of plastic, and the staff can see the liquid level in the water tank 221 and replenish the water in time. In addition, the forward direction of the cutting knife 212 is defined as the front side, which will not be repeated here.

[0059] The above is the overall workflow of the present invention. Just repeat this step next time you use it.
