Description

Technical Field

[0001] The present invention relates to the technical field of pavement breaking devices, in particular to a pavement breaking device for repairing road cracks. Background Art

[0002] Roads are key carriers of transportation. With long-term use, cracks often appear on roads due to various reasons. However, if these cracks are not dealt with in time, the cracks will gradually expand and eventually cause the road surface to become more damaged. Therefore, once cracks appear on the road, maintenance personnel should use road pavement crushing devices in time to crush the damaged road surface and create conditions for road repair and reconstruction.

[0003] In the existing technology, the existing road breaking device can break up the damaged road surface during actual use, creating conditions for road repair and reconstruction and improving the service life of the road. However, it does not have an isolation function. When the road breaking device is pushed by maintenance personnel and travels on the road surface, the tip of the drill rod on the road breaking device is raised and exposed and can easily collide with surrounding objects due to the shaking of the device during movement. If there are pedestrians nearby, it may also cause accidental injuries to pedestrians.

When the road surface crushing device moves to the appropriate position, the two isolation blocks will separate again. At this time, the controller, oil pump, oil inlet pipe, oil outlet pipe, electric reversing valve, two oil pipe bodies, oil tank and return oil pipe are first used to make the telescopic end of the oil cylinder continuously expand and contract inside the oil pipe. Then, the cooperation of the continuously shrinking telescopic end of the oil cylinder, the slide groove, the slider, the connecting seat and the connecting block can be used to make the drill rod continuously move up and down vertically.

The crushing mechanism 1 includes a mobile car 101, a placement box 102 is fixed on the handrail of the mobile car 101, and a controller 103 is installed on the bottom of the inner wall of the placement box 102. The two perforated blocks 201 and the U-shaped block 209 are fixed on the placement plate of the mobile car 101, and the lower sides of the two isolation blocks 207 are fixed to the placement plate of the mobile car 101. The sides and the bottoms of the two internal threaded blocks 208 are in contact with the upper side of the placement plate of the mobile vehicle 101, and the bottoms of the two L-shaped blocks 203 are in contact with the upper side of the placement plate of the mobile vehicle 101.

One end of the long rod 204 is movable through the outer wall of the mounting bracket 104 and the inner wall of the mounting bracket 104. The inclination sensor 214 is installed on the outer wall of the mounting bracket 104. An oil cylinder 108 is installed on the mounting bracket 104. The telescopic end of the oil cylinder 108 is installed with a connecting seat 109, and the bottom end of the connecting seat 109 is threadedly connected to the drill rod 110.

[0036] In this embodiment, when the road breaking device is parked on the road and the controller 103 is powered by the battery 121 and the tilt sensor 214 is turned on, the tilt sensor 214 activated at this time will constantly detect the tilt angle of the mounting frame 104, and transmit the tilt angle data detected each time to the controller 103 in the form of an electrical signal. Subsequently, the controller 103 will compare the tilt angle data received each time with the tilt angle range set in advance by the controller 103. When the tilt angle data received by the controller 103 is within the tilt angle range set in advance by the controller 103, it means that the road breaking device has not moved or has moved to a suitable position and will no longer move. At this time, the controller 103 will start the motor 212, the motor 212 started at this time (the output end of the motor 212 is in forward rotation at this time) will drive the corresponding gear 211 to rotate under the cooperation of the other short rod 210, the corresponding bearing and the U-shaped block 209, and the rotating gear 211 will make one of the short rods 210 rotate under the cooperation of the U-shaped block 209, the gear 211 meshing therewith and the corresponding bearing, and then one of the rotating short rods 210 will drive the two screw rods 213 (the threads of the two screw rods 213 are opposite) to rotate at the same time, and then the two rotating screw rods 213 will make the two internal thread blocks 208 move towards each other under the cooperation of the placement plate of the mobile vehicle 101, and then the two internal thread blocks 208 moving towards each other will be on the two sets of fixed blocks 206 and two With the cooperation of the steel wire rope 202, the two perforated blocks 201, the two L-shaped blocks 203 and the long rod 204, the two isolation blocks 207 move in opposite directions. The two isolation blocks 207 that move at the same time will compress the two springs 205 with the cooperation of the two L-shaped blocks 203 and the long rod 204. When the two internal thread blocks 208 move toward each other and cannot move, the controller 103 will pause the motor 212. At this time, the tip of the drill rod 110 will be exposed. When the road breaking device moves on the road, the drill rod 110 will be lifted (the handrail of the mobile vehicle 101 will move down significantly, and the support block of the mobile vehicle 101 will be lifted up significantly). At the same time, the mounting frame 104 will tilt. At this time, the inclination angle received by the controller 103 The angle data will not be within the inclination angle range pre-set by the controller 103. At this time, the controller 103 will start the motor 212. The started motor 212 (the output end of the motor 212 is reversed at this time) will allow the two internal thread blocks 208 to move in opposite directions with the cooperation of the previous linkage components. At the same time, the two isolation blocks 207 will also be reset to their original positions with the cooperation of the previously matched components and the rebound force of the two springs 205.

A drill rod 110 is connected, an electric reversing valve 111 is installed near the top of the inner wall of the mounting frame 104, and the two oil outlet ends of the electric reversing valve 111 are installed with an oil pipe body 112. An oil tank 113 is fixed to the surface of the placement plate of the mobile vehicle 101, and an oil return pipe 114 is installed at the oil return end of the electric reversing valve 111. The oil outlet end of the return pipe 114 is installed with the oil inlet end of the oil tank 113. An oil pump 115 is installed on the surface of the placement plate of the mobile vehicle 101, and the oil inlet end of the oil pump 115 is installed with an oil inlet pipe 116. The oil inlet end of the oil inlet pipe 116 is installed with the oil outlet end of the oil tank 113.

The inner wall of the mounting frame 104 is provided with an annular hole 123 near the bottom. The oil outlet pipe 117 is movably sleeved inside the annular hole 123. The inner wall of the mounting frame 104 is provided with a rectangular hole 125. The telescopic end of the oil cylinder 108 is movably sleeved inside the rectangular hole 125.

[0038] In this embodiment, when the road crushing device moves to the appropriate position (the place where the damaged road surface needs to be crushed), the movement of the road crushing device is stopped. At this time, the two isolation blocks 207 will separate again, allowing the tip of the drill rod 110 to be exposed. Then the staff will use the controller 103 to start the oil pump 115 and the electric reversing valve 111. The started oil pump 115 will then, with the cooperation of the oil inlet pipe 116, draw out the hydraulic oil in the oil tank 113 and then deliver it to the inside of the oil outlet pipe 117. Then, through the cooperation of the electric reversing valve 111 and one of the oil pipe bodies 112 (corresponding to the port at the top of the oil cylinder 108), the hydraulic oil is delivered to the corresponding chamber inside the oil cylinder 108. When hydraulic oil is continuously injected into the internal chamber of the oil cylinder 108, the telescopic end of the oil cylinder 108 will move out from the inside of the oil cylinder 108, and the moving oil cylinder 108 will also cooperate with the slide groove 105, the slider 106, the connecting block 107 and the connecting seat 109. When the oil cylinder 108 is in a state of tension, the oil in the oil return pipe 114 is released, and the oil in the oil tank 113 is returned to the oil tank 113. When the oil cylinder 108 is in a state of tension, the oil in the oil return pipe 114 is released, and the oil in the oil tank 113 is returned to the oil tank 113. When the oil cylinder 108 is in a state of tension, the oil in the oil return pipe 114 is released, and the oil in the oil tank 113 is returned to the oil tank 113. When the oil cylinder 108 is in a state of tension, the oil in the oil return pipe 114 is released, and the oil in the oil tank 113 is returned to the oil tank 113. When the oil cylinder 108 is in a state of tension, the oil in the oil return pipe 114 is released, and the oil in the oil tank 113 is returned to the oil tank 113.

[0039] The effect and working principle of the entire mechanism are as follows: when a road crack needs to be repaired, the controller 103 is first turned on by the power supply of the battery 121, and then the basic usage program is set, and then the inclination angle range is set. When everything is ready, the inclination sensor 214 is turned on by the controller 103. At this time, the inclination sensor 214 will always detect the inclination angle of the mounting frame 104, and transmit the inclination angle data detected each time to the controller 103 in the form of an electrical signal. Then the controller 103 will compare the inclination angle data received each time with the inclination angle range set in advance by the controller 103. When the inclination angle data received by the controller 103 is within the inclination angle range set in advance by the controller 103, , this indicates that the road breaking device has not moved or has moved to a suitable position and will no longer move. At this time, the controller 103 will start the motor 212. The started motor 212 (the output end of the motor 212 is forward) will drive the corresponding gear 211 to rotate under the cooperation of the other short rod 210, the corresponding bearing and the U-shaped block 209. The rotating gear 211 will rotate one of the short rods 210 under the cooperation of the U-shaped block 209, the gear 211 meshing therewith and the corresponding bearing. Subsequently, one of the rotating short rods 210 will drive two screws 213 (the threads of the two screws 213 are opposite) to rotate at the same time. Then, the two rotating screws 213 will make the two The internal thread blocks 208 move toward each other, and then the two internal thread blocks 208 moving toward each other will, with the cooperation of the two sets of fixed blocks 206, the two steel wire ropes 202, the two perforated blocks 201, the two L-shaped blocks 203 and the long rod 204, allow the two isolation blocks 207 to move in opposite directions. At the same time, the two isolation blocks 207 moving at the same time will, with the cooperation of the two L-shaped blocks 203 and the long rod 204, compress the two springs 205. When the two internal thread blocks 208 move toward each other and cannot move, the controller 103 will pause the motor 212. At this time, the tip of the drill rod 110 will be exposed. When the road breaking device moves on the road, the drill rod 110 will be lifted (the handrail of the mobile vehicle 101 will move down significantly, and the handrail of the mobile vehicle 101 will move down significantly). The supporting block will be greatly lifted), and the mounting frame 104 will tilt. At this time, the inclination angle data received by the controller 103 will not be within the inclination angle range set in advance by the controller 103. At this time, the controller 103 will start the motor 212. The motor 212 started at this time (the output end of the motor 212 is reversed at this time) will allow the two internal thread blocks 208 to move in opposite directions under the cooperation of the previous linkage components. At the same time, the two isolation blocks 207 will also be reset to their original positions under the cooperation of the previously matched components and the rebound force of the two springs 205. When the two isolation blocks 207 are reset to their original positions, the tip of the drill rod 110 will be wrapped up. At this time, the tip of the drill rod 110 will not collide with surrounding objects when the road breaking device moves.When the pavement crushing device moves to the appropriate position (where the damaged pavement needs to be crushed), the pavement crushing device is stopped, and the two isolation blocks 207 are separated again, exposing the tip of the drill rod 110. The staff then uses the controller 103 to start the oil pump 115 and the electric reversing valve 111. The oil pump 115 that is started will then, in cooperation with the oil inlet pipe 116, draw the hydraulic oil from the oil tank 113 and then deliver it to the inside of the oil outlet pipe 117. Then, the oil passes through the electric reversing valve 111 and the oil pump 115. The cooperation of one of the oil pipe bodies 112 (corresponding to the port at the top of the oil cylinder 108) transports the hydraulic oil to the corresponding chamber inside the oil cylinder 108. When the hydraulic oil is continuously injected into the internal chamber of the oil cylinder 108, the telescopic end of the oil cylinder 108 will move out from the inside of the oil cylinder 108, and the moving oil cylinder 108 will also drive the drill rod 110 to move vertically downward under the cooperation of the slide groove 105, the slider 106, the connecting block 107 and the connecting seat 109. At the same time, the hydraulic oil in the other chamber of the oil cylinder 108 will be pumped out from the other oil pipe body 112 (corresponding to the port at the bottom of the oil cylinder 108). The oil is discharged from the oil reversing port 111, then enters the interior of the electric reversing valve 111, and then enters the interior of the return oil pipe 114, and then flows back to the interior of the oil tank 113 to start a new cycle. When the telescopic end of the oil cylinder 108 moves out of the interior of the oil cylinder 108 to a suitable length, the controller 103 will change the direction of the oil circuit through the cooperation of the electric reversing valve 111, so that the telescopic end of the oil cylinder 108 moves back to the interior of the oil cylinder 108. When the telescopic end of the oil cylinder 108 moves back to the initial position, the controller 103 will again change the direction of the oil circuit through the cooperation of the electric reversing valve 111, so that the oil The telescopic end of the cylinder 108 moves out of the interior of the oil cylinder 108, and this reciprocating movement allows the drill rod 110 to continuously move up and down. That is, the damaged road surface can be broken up by the drill rod 110 moving up and down. When the damaged road surface is broken up, the controller 103 can be used to directly shut down the oil pump 115 and the electric reversing valve 111. Then, the inclination sensor 214 is turned off. Then, the motor 212 and the previous linkage components are used to make the two internal thread blocks 208 move in opposite directions until the two isolation blocks 207 return to their original positions. Then, the motor 212 is paused.

[0040] The mobile vehicle 101 is composed of a handrail, a frame, an axle frame, wheels, a placement plate, bearings, bolts, nuts, support blocks and an axle.

[0041] The electric reversing valve 111 , the battery 121 , the motor 212 , the oil pump 115 and the tilt sensor 214 are all electrically connected to the controller 103 .

[0042] The buffer sleeve 120, the battery box 118 and the two fixing plates 122 cooperate together to prevent the battery 121 from being vibrated and damaged when the road breaking device travels on an uneven road.

[0043] Among them, the controller 103 (PLC controller), oil cylinder 108, electric reversing valve 111, oil pump 115, battery 121, motor 212 and tilt sensor 214 are all existing technologies, and their models can be selected according to actual conditions, so no further explanation is given here.
