Description

Technical Field

[0001] The invention belongs to the technical field of pavement cutting equipment, and more specifically, relates to an anti-deviation pavement cutting machine. Background Art

[0002] During road construction, concrete will generate internal stress due to temperature changes during the solidification and hardening process. If these stresses are not properly released, cracks will form in the road surface, affecting the quality and service life of the road surface. By pre-cutting grooves of a certain width and depth, the so-called slits, the cracks can be guided to develop along a predetermined path, thereby controlling the shape and location of the cracks and reducing the impact on the overall performance of the road surface.

[0003] In addition, the slits can also help improve the drainage performance of the road surface and the comfort of vehicle driving. The slits can serve as drainage channels, reduce the accumulation of water under the road surface, and reduce the damage to the road surface caused by freeze-thaw. At the same time, the appropriate slit spacing and depth can reduce the impact of vehicles on the road surface when driving, and extend the service life of the road surface.

[0025] The anti-deviation pavement seam cutting machine provided by the present invention is now described.

[0026] Please also read Figure 1 and Figure 2The anti-deviation road surface seam cutting machine includes a body 1 with a plurality of rollers 103 at the bottom, a water tank 2 is provided on the body 1, the water tank 2 is filled with cooling water, a steering mechanism 3 is provided on one side of the water tank 2, the steering mechanism 3 is connected to the roller 103 on the front side of the body 1, and the steering mechanism 3 is used to drive the roller 103 on the front side of the body 1 to deflect to change the forward direction of the body 1; a mounting plate 101 is provided on one side of the water tank 2, the mounting plate 101 is arranged above the steering mechanism 3, a driving device 4 is provided on the mounting plate 101, a seam cutting mechanism 5 is connected to the power output end of the driving device 4, a geomagnetic pointing mechanism 6 is provided on the seam cutting mechanism 5, and the geomagnetic pointing mechanism 6 is electrically connected to the steering mechanism 3, when the angle between the forward direction of the seam cutting mechanism 5 and the direction of the geomagnetic pointing mechanism 6 changes, the steering mechanism 3 drives the roller 103 to deflect so as to restore the preset angle between the forward direction of the seam cutting mechanism 5 and the direction of the geomagnetic pointing mechanism 6.

[0027] The beneficial effect of the anti-deviation road surface seam cutting machine provided in the present embodiment is as follows: compared with the prior art, the anti-deviation road surface seam cutting machine provided in the present embodiment is provided with a vehicle body 1, a water tank 2, a driving device 4 and a seam cutting mechanism 5, so that when the driving device 4 is turned on, it is only necessary to push the vehicle body 1 forward to complete the seam cutting of the road surface, and at the same time, by providing a geomagnetic pointing mechanism 6 and a steering mechanism 3 to cooperate, and utilizing the principle that the geomagnetic pointing mechanism 6 always points to the same direction, when the seam cutting starts, the seam cutting direction is determined, that is, the angle between the forward direction of the seam cutting mechanism 5 and the direction of the geomagnetic pointing mechanism 6 is determined. At this time, if the forward direction of the vehicle body 1 deviates, the angle between the forward direction of the seam cutting mechanism 5 and the direction of the geomagnetic pointing mechanism 6 changes, and at this time, the steering mechanism 3 drives the vehicle body 1 to turn until the preset angle between the forward direction of the seam cutting mechanism 5 and the direction of the geomagnetic pointing mechanism 6 is restored, that is, to ensure that the cut seam remains straight.

[0028] like Figure 3 and Figure 4 As shown, four rollers 103 are provided, each roller 103 is provided at the four corners of the vehicle body 1, a sealed shell 102 is provided on the top of the vehicle body 1, a sealed cavity is provided inside the sealed shell 102, the steering mechanism includes a steering rod 301, the steering rod 301 is provided with the tops of the two rollers on the front side of the vehicle body, a steering gear 302 is provided on the top of the steering rod 301, a steering worm 303 is rotatably provided between the corresponding side walls of the sealed shell 102, the steering worm 303 is meshed with the steering gear 302, a first driving gear 304 is provided on the steering worm 303, a steering motor 305 is provided in the sealed cavity, the steering motor 305 is provided on one side of the steering worm 303, a second driving gear 306 is provided at the power output end of the steering motor 305, and the first driving gear 304 is meshed with the second driving gear 306.

[0029] The setting of the sealing shell 102 can cover the steering mechanism 3 in the sealing chamber, thereby protecting the steering mechanism 3 and preventing external dust or cement debris generated during the slitting process from damaging the steering mechanism 3. The setting of the steering gear 302 and the steering worm 303 in the steering mechanism 3 enables the steering worm 303 to drive the two rollers 103 on the front side of the vehicle body 1 to turn when rotating, so that the forward direction of the vehicle body 1 changes, that is, the direction of the slit changes, so as to achieve the purpose of correcting the slit.

[0030] Combination Figure 2 , Figure 5 and Figure 6 As shown, the geomagnetic pointing mechanism 6 includes a shockproof component arranged on the slitting mechanism 5 and a pointing component arranged on the shockproof component, the pointing component is electrically connected to the shockproof component, the shockproof component includes a connecting rod 601 arranged on the top of the slitting mechanism 5, a first connecting plate 602 is provided on the top of the first connecting plate 602, a shockproof tube 603 is provided on the top of the shockproof tube 603, a shockproof groove 605 is provided on the top of the shockproof tube 603, a shockproof rod 604 is inserted in the shockproof groove 605, a first shockproof spring 606 is provided between the bottom end of the shockproof rod 604 and the bottom of the shockproof groove 605, a plurality of second shockproof springs 607 are provided between the side wall of the shockproof rod 604 and the side wall of the shockproof groove 605, each second shockproof spring 607 is evenly arranged along the circumference of the shockproof rod 604, a second connecting plate 608 is provided on the top of the shockproof rod 604, and the pointing component is provided on the second connecting plate 608.

[0031] The first anti-vibration spring 606 can prevent the vertical movement of the anti-vibration rod 604. The second anti-vibration spring 607 can prevent the horizontal movement of the anti-vibration rod 604. The two springs can prevent the second connecting plate 608 from being vibrated, thereby preventing the vibration generated during the slitting process from causing adverse effects on the pointing assembly.

[0032] Combination Figure 7 and Figure 8 As shown, the pointing assembly includes a steering groove arranged at the top of the second connecting plate 608, a thread is arranged on the side wall of the steering groove, a steering cylinder 609 is screwed in the steering groove, a deflection groove 610 is arranged on the side wall of the steering cylinder 609, and a first contact switch 611 and a second contact switch 612 are arranged on the two corresponding side walls of the deflection groove 610. When the first contact switch 611 is closed, the steering motor rotates forward. When the second contact switch 612 is closed, the steering motor reverses. A pointing rod 613 is rotatably arranged in the steering cylinder, a magnetic needle 614 is arranged on the pointing rod 613, and a contact needle 615 is arranged on the top of the pointing rod 613. The magnetic needle 614 and the contact needle 615 are arranged at intervals, and a part of the contact needle 615 extends into the deflection groove 610.

[0033] At the beginning, the steering cylinder 609 is rotated so that the contact pin 615 can be partially set in the deflection groove 610 when there is no external force, and the contact pin 615 does not contact any of the first contact switch 611 and the second contact switch 612. When the forward direction of the vehicle body 1 is deflected, the slitting mechanism 5 will be driven to turn, and the direction of the deflection groove 610 will change at this time. However, since the direction of the magnetic needle 614 will not change, the direction of the contact pin 615 will not change. The change in the direction of the deflection groove 610 will cause the contact pin 615 to contact the first contact switch 611 or the second contact switch 612, so that the steering motor drives the roller 103 to turn, thereby changing the forward direction of the vehicle body 1 and driving the direction of the deflection groove 610 to change until the contact pin 615 is released from the first contact switch 611 or the second contact switch 612, and the steering motor 305 is turned off, and the deviation correction of the slitting is completed at this time.

[0034] As a preferred technical solution, a limit pin 616 is provided in the deflection groove 610 , and the tip of the limit pin 616 is arranged toward the center of the steering cylinder. In the initial state, the tip of the contact pin 615 is opposite to the tip of the limit pin 616 .

[0035] The setting of the limiting pin 616 can facilitate the adjustment of the direction of the deflection slot 610 , so that the contact pin 615 is set in the deflection slot 610 and the contact pin 615 does not contact either the first contact switch 611 or the second contact switch 612 .

[0036] like Figure 3 , Fig. 9 and Fig.10 As shown, a fixed plate 104 is provided on one side of the sealing shell 102, and a strip hole 105 is provided on the fixed plate 104. The slitting mechanism 5 includes a slitting shaft 501, a slitting saw blade 502 is provided on the slitting shaft 501, and a protective sleeve 503 is provided on the outer side of the slitting saw blade 502. The slitting shaft 501 is arranged through the protective sleeve 503, and the slitting saw blade 502 is arranged on the outer side of the fixed plate 104. The slitting shaft 501 passes through the strip hole 105 and is arranged on the inner side of the fixed plate 104. A driving shaft 401 is provided at the power output end of the driving device 4, and a first driving gear 304 is provided on the driving shaft 401. A second driving gear 306 is provided on the slitting shaft 501, and a transmission chain 106 is provided on the outer sides of the first driving gear 304 and the second driving gear 306, so that the driving device 4 can drive the slitting shaft 501 to rotate.

[0037] In this embodiment, a slide groove is provided on one side of the strip hole 105, a slitting plate is slidably provided in the slide groove, and the slitting shaft 501 is rotatably provided on the slitting plate. The slitting plate and the slide groove are provided so that the slitting shaft 501 can always be in a horizontal state. The chain 106 is provided so that the driving shaft 401 can drive the rotation of the slitting shaft 501, thereby driving the slitting saw blade 502 to rotate, thereby completing the slitting operation on the road surface.

[0038] like Figure 2 As shown, a lifting plate 107 is provided at the top of the fixed plate 104, and a lifting motor 108 is provided on the lifting plate 107. A lifting rod 109 is provided at the power output end of the lifting motor 108. The lifting rod 109 passes through the lifting plate 107 and is connected to the protective cover 503. The lifting motor 108 is used to drive the slitting mechanism 5 to rise or fall. A tensioning assembly is provided on the inner side of the fixed plate 104, and the transmission chain 106 crosses the tensioning assembly. The tensioning assembly is used to tighten the transmission chain 106.

[0039] The arrangement of the lifting plate 107, the lifting motor 108 and the lifting rod 109 allows the setting height of the slitting mechanism 5 to be changed. On the one hand, slits of different depths can be cut to meet different slitting requirements. On the other hand, the slitting mechanism 5 can be set to release contact with the ground when slitting is not required, thereby facilitating the movement and transportation of the vehicle body 1. The arrangement of the tensioning assembly ensures that no matter how the distance between the driving shaft 401 and the slitting shaft 501 changes, the chain 106 is in a tensioned state, thereby facilitating the driving shaft 401 to drive the slitting shaft 501 to rotate.

[0040] Specifically in this embodiment, the tensioning assembly includes a tensioning groove 110, which is arranged on the inner wall of the fixed plate 104. A first tensioning plate 111 is slidably provided in the tensioning groove 110, and a tensioning shaft 112 is rotatably provided on the first tensioning plate 111. A third driving gear is provided on the tensioning shaft 112. The chain 106 is arranged across the third driving gear. A second tensioning plate 114 is provided on one side of the strip hole 105. The first tensioning plate 111 is U-shaped, and both ends of the first tensioning plate 111 extend outward from the tensioning groove 110. A tensioning spring 113 is provided between the first tensioning plate 111 and the second tensioning plate 114, and when the first tensioning plate 111 is provided at the end of the tensioning groove 110 away from the strip hole 105, the tensioning spring 113 is in a compressed state.

[0041] When the distance between the driving shaft 401 and the slitting shaft 501 increases, the first tensioning plate 111 moves toward the direction close to the strip hole 105, the tensioning spring 113 is compressed to store energy, and the chain 106 is in a tensioned state; when the distance between the driving shaft 401 and the slitting shaft 501 decreases, the first tensioning plate 111 moves toward the direction away from the strip hole 105, the tensioning spring 113 releases energy and stretches, and the chain 106 is still in a tensioned state.

[0042] In addition, a contact plate 115 is provided on one side of the first tensioning plate 111, and the contact plate 115 includes a vertical plate 116 arranged vertically and a horizontal plate 117. The bottom end of the vertical plate 116 is connected to the first tensioning plate 111, and the top end of the vertical plate 116 is connected to one end of the horizontal plate 117. The horizontal plate 117 is arranged above the driving shaft 401. A limit plate 118 is provided on the inner wall of the fixed plate 104, and a third contact switch 119 is provided below the limit plate 118. When the third contact switch 119 and the first contact switch 611 are closed at the same time, the steering motor rotates forward; when the third contact switch 119 and the second contact switch 612 are closed at the same time, the steering motor reverses; when the slitting saw blade 502 descends and contacts the ground with the slit, the horizontal plate contacts the third contact switch 119, and the third contact switch 119 is closed.

[0043] The setting of the limit plate 118 and the third contact switch 119 ensures that when the slitting saw blade 502 is out of contact with the ground, the third contact switch 119 will not be closed, and the traveling direction of the vehicle body 1 does not need to be corrected at this time, that is, when the contact pin 615 is in contact with the first contact switch 611 or the second contact switch 612, the steering motor 305 will not work, which is convenient for the movement and transportation of the vehicle body 1. When slitting is required, the slitting saw blade 502 is in contact with the ground, and the third contact switch 119 is closed. At this time, the traveling direction of the vehicle body 1 needs to be corrected. Once the contact pin 615 is in contact with either the first contact switch 611 or the second contact switch 612, the steering motor 305 starts to work and the correction begins.

[0044] Finally, a water outlet pipe 201 is provided at the bottom of the water tank 2, the bottom end of the water outlet pipe 201 faces the bottom of the slitting saw blade 502, and a solenoid valve 202 is provided on the water outlet pipe 201; the driving device 4 includes a driving motor and a battery, the battery is electrically connected to the driving motor, and the battery is electrically connected to the steering motor, the first contact switch 611, the second contact switch 612, the third contact switch 119, the lifting motor 108 and the solenoid valve 202. The battery can provide energy for the electrical components on the vehicle body 1.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
