Description

Technical Field

[0001] The present invention relates to the technical field of road crack repair, in particular to a road crack repair device. Background Art

[0002] When a highway is in use for too long, the material will age due to external environmental factors and the hardness of the road surface will decrease. When the pressure on the road surface is too great, cracks will appear on the road surface. The cracks will not only affect the overall appearance, but also cause rust and corrosion of the internal steel bars, increasing safety hazards. In order to minimize the losses, it is often necessary to use highway crack repair equipment to repair highway cracks. Secondly, the difference in crack depth poses a severe challenge to the repair technology.

[0003] Current highway crack repair equipment usually relies on the material's own weight to pour asphalt. When the crack is deep, the asphalt cannot completely expel the deep air due to increased viscosity and friction resistance of the crack wall during the flow process, forming closed bubbles. These bubbles burst under the action of vehicle loads in the later stage, causing local settlement. Secondly, when the asphalt settles locally and there is a height difference, a second asphalt filling is required. Since the asphalt filled for the first time is completely solidified, the new asphalt flows naturally under the action of gravity and is difficult to break through the closed interface of the old asphalt. Stratification may occur, and repeated rolling by vehicle loads will cause secondary damage to the repaired area.

[0004] In view of the above problems, a highway crack repairing device is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a highway crack repair device.

A first through hole is penetrated on the surface and one end of the filling pipe, and a second through hole corresponding to the first through hole is penetrated on the surface and one end of the insertion pipe. A heating wire is installed inside the insertion pipe, and an elastic limit seat is slidably connected on the surface of the insertion pipe, and the elastic limit seat is slidably connected to the movable seat. When the insertion pipe is inserted into the crack, the elastic limit seat contacts the ground.

[0008] Furthermore, the driving frame includes a frame plate and a first frame fixed to one end of the frame plate, a first motor is fixedly installed inside the first frame, a screw is rotatably connected inside the frame plate, and the screw is fixedly connected to the output end of the first motor.

[0009] Furthermore, the guide seat includes a vertical plate and a vertical groove opened on one side of the vertical plate. The vertical plate is fixedly connected to the frame plate. Multiple S-shaped grooves are opened on one side of the vertical plate, and the multiple S-shaped grooves are interconnected, and the vertical grooves are connected to the S-shaped grooves.

[0010] Furthermore, the movable seat includes a threaded plate and a rectangular plate fixed on one side of the threaded plate, the threaded plate is threadedly connected to the screw rod, and the threaded plate is slidingly connected to the frame plate, a protrusion is slidingly connected inside the rectangular plate, a support plate is fixedly installed on one side of the protrusion, and the support plate is in contact with the rectangular plate.

[0011] Furthermore, the telescopic part includes a fixed column and a first disc fixed inside the fixed column, an electromagnet is fixedly installed inside the fixed column, a connecting rod is slidably connected to one side of the first disc, a roller is rotatably connected to one end of the connecting rod, a clamping ring is fixedly installed on the surface of the connecting rod, and the clamping ring is slidably engaged with the inner wall of the fixed column, two limit rods are fixedly installed on one side of the first disc, the clamping rings are slidably connected to the two limit rods, and a magnet block is fixedly installed at one end of the connecting rod.

[0012] Furthermore, two arcuate grooves are correspondingly opened inside the fixed column, and the retaining ring includes a second disc and arcuate blocks slidably connected to both sides of the second disc. The two arcuate blocks are slidably connected to the two arcuate grooves, and first springs are fixedly installed inside both sides of the second disc, and the first springs are fixedly connected to the arcuate blocks.

[0013] Furthermore, a connecting pipe is installed on one side of the pump body, and the connecting pipe is connected to the filling pipe. A telescopic pipe is installed on one side of the pump body, and the telescopic pipe is connected to the caulking machine.

[0014] Furthermore, the driving member includes a second frame and a second motor fixed inside the second frame, and a first gear is fixedly installed on the output end of the second motor.

[0015] Furthermore, a second gear is fixedly mounted on one end of the insertion tube, and the first gear is meshedly connected with the second gear.

[0016] Furthermore, the elastic limit seat includes a sleeve and a movable plate fixed at one end of the sleeve, two sliding rods are fixedly installed on one side of the movable plate, and the two sliding rods are slidably connected to the support plate, and two second springs are fixedly installed on one side of the movable plate, and one end of the two second springs is fixedly connected to the support plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the initial state, the first through hole and the second through hole are misaligned with each other. As the pump body continuously transports asphalt into the filling tube, the pressure in the filling tube accumulates rapidly. Subsequently, the insertion tube is driven to rotate by the driving member, so that the first through hole and the second through hole coincide with each other. Under the high-pressure state, the asphalt is instantly sprayed into the crack through the first through hole and the second through hole, forming a multi-point synchronous impact. Through the cooperation of the guide seat and the telescopic member, the movable seat moves downward and left and right at the same time, so that the filling tube and the insertion tube move back and forth, which can increase the spraying range. The impact force generated by the high-pressure spraying can quickly squeeze out the air in the crack. At the same time, the asphalt penetrates into the fine bifurcation or narrow section under high pressure, reducing incomplete filling caused by viscosity.

[0019] Since the insertion tube can directly penetrate into the bottom of the crack, it avoids insufficient bottom filling due to gravity attenuation when asphalt is poured downward from the surface, and reduces the blocking of the lower air by the upper layer of asphalt. When the asphalt settles after one filling, the filling tube and the insertion tube are heated by the heating wire built into the insertion tube. After the insertion tube is inserted into the first solidified asphalt, the old asphalt around the insertion point is softened by heat conduction. At the same time, the insertion tube moves back and forth along the depth direction of the crack. On the one hand, the local structure of the old asphalt is broken through physical disturbance, so that the softened old asphalt forms a loose transition layer. On the other hand, the friction of the insertion tube is used to further disperse the heat and expand the softening range. Then, asphalt is sprayed again for filling to prevent stratification.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In order to solve the technical problem that asphalt cannot completely expel deep air due to increased viscosity and friction resistance of crack walls during flow, forming closed bubbles, resulting in local settlement and possible stratification during secondary asphalt filling, such as Figures 1-10 As shown, the following preferred technical solutions are provided:

[0033] like Figure 1-Figure 3 and Figure 10 As shown, a highway crack repair equipment includes a caulking machine 1, which is used to store asphalt inside the caulking machine 1. By pushing the caulking machine 1 to move next to the highway crack, convenience is improved. A driving frame 2 is fixedly installed on one side of the caulking machine 1, and a guide seat 3 is fixedly connected to one side of the driving frame 2. A movable seat 4 is slidably installed on the surface of the driving frame 2. The movable seat 4 can be driven to move by the driving frame 2, which is convenient for adjusting the height of the movable seat 4. A telescopic member 5 is provided on one end of the movable seat 4 near the guide seat 3, which is inserted into one side of the guide seat 3 through the telescopic member 5. When the driving frame 2 drives the movable seat 4 to move downward, the cooperation of the guide seat 3 and the telescopic member 5 makes the movable seat 4 move left and right while moving downward, which can increase the range of caulking. A pump body 6 is fixedly installed on the top of the movable seat 4, and the pump body 6 is connected to the caulking machine 1. A driving member 7 is fixedly installed on one side of the movable seat 4.

[0034] The driving frame 2, the telescopic member 5 and the driving member 7 are all electrically connected to the controller. A filling pipe 8 is connected to one side of the movable seat 4. The pump body 6 is connected to the filling pipe 8. The asphalt can be transported to the inside of the filling pipe 8 through the pump body 6. The asphalt is filled into the road gaps through the filling pipe 8. The surface of the filling pipe 8 is connected to the insertion pipe 9 for rotation. The driving member 7 is in transmission connection with the insertion pipe 9. The insertion pipe 9 can be driven to rotate by the driving member 7, and the rotation of the insertion pipe 9 plays a role in adjusting the filling amount. A first through hole 10 is opened through the surface and one end of the filling pipe 8, and a second through hole 20 corresponding to the first through hole 10 is opened through the surface and one end of the insertion pipe 9.

[0035] The controller can control the driving frame 2 to drive the moving seat 4 to move downward for a distance, and one end of the insertion tube 9 is inserted into the gap, so that the controller controls the telescopic member 5 to move, and one end of the telescopic member 5 is inserted into the guide seat 3. When the driving frame 2 drives the moving seat 4 to move downward, the cooperation of the guide seat 3 and the telescopic member 5 makes the moving seat 4 move left and right while moving downward, so that the filling tube 8 and the insertion tube 9 can be driven to move left and right. In the initial state, they are misaligned with the first through hole 10 and the second through hole 20, which can seal the first through hole 10. At the same time, asphalt can be transported to the inside of the filling tube 8 through the pump body 6. At this time, the insertion tube 9 is driven to rotate by the driving member 7 so that the first through hole 10 and the second through hole 20 coincide with each other. High-pressure asphalt is instantly sprayed into the crack through the first through hole 10 and the second through hole 20, forming a multi-point synchronous impact. The impact force generated by the high-pressure injection can quickly expel the air in the crack and can be discharged from the top of the crack or the gap not blocked by asphalt. At the same time, the asphalt penetrates into the fine bifurcation or narrow section under high pressure, reducing incomplete filling caused by viscosity.

[0036] A heating wire 30 is installed inside the insertion tube 9. The built-in heating wire 30 of the insertion tube 9 needs to be made of high-temperature resistant materials, such as nickel-chromium alloy. The heating temperature can be controlled at 160-200°C, which is close to the softening point of asphalt. Because if there is a low-temperature zone inside the filling tube 8, the asphalt is easy to solidify in the first through hole 10 and the second through hole 20 or the inner wall, resulting in blockage or injection pressure fluctuations. The heating wire 30 can evenly fill the asphalt inside the tube 8 and the insertion tube 9, eliminate local cooling dead corners, and ensure injection continuity. The surface of the insertion tube 9 is slidably connected to an elastic limit seat 40, and the elastic limit seat 40 is slidably connected to the movable seat 4. When the insertion tube 9 is inserted into the crack, the elastic limit seat 40 contacts the ground, and the reaction force causes the elastic limit seat 40 to move upward. The elastic limit seat 40 can close the second through hole 20 on the insertion tube 9, so it can be adjusted according to the depth of the crack.

[0037] First, push the crack filling machine 1 to move to the side of the road crack, and then control the driving frame 2 through the controller to drive the moving seat 4 to move downward for a distance, and insert one end of the insertion tube 9 into the gap, so as to control the telescopic member 5 to move through the controller, and insert one end of the telescopic member 5 into the guide seat 3. When the driving frame 2 drives the moving seat 4 to move downward, the cooperation of the guide seat 3 and the telescopic member 5 makes the moving seat 4 move left and right while moving downward, thereby driving the filling tube 8 and the insertion tube 9 to move left and right. In the initial state, the first through hole 10 and the second through hole 20 are misaligned with each other, which can seal the first through hole 10. At the same time, the pump body 6 can Asphalt is transported to the inside of the filling pipe 8. As the pump body 6 continuously transports asphalt into the filling pipe 8, the pressure in the filling pipe 8 accumulates rapidly. Then, the driving member 7 drives the insertion pipe 9 to rotate, so that the first through hole 10 and the second through hole 20 coincide with each other. Under high pressure, the asphalt is instantly sprayed into the crack through the first through hole 10 and the second through hole 20, forming a multi-point synchronous impact. Moreover, since the filling pipe 8 and the insertion pipe 9 move back and forth, the spraying range can be increased. The impact force generated by the high-pressure spraying can quickly squeeze out the air in the crack and discharge it from the top of the crack or the gap not blocked by asphalt. At the same time, the asphalt penetrates into the fine bifurcation or narrow section under high pressure, reducing incomplete filling caused by viscosity.

[0038] And the degree of overlap between the first through hole 10 and the second through hole 20 can be adjusted according to needs. When the first through hole 10 and the second through hole 20 only overlap half, the spraying distance can be significantly increased, which is especially suitable for filling deep cracks or cracks with complex shapes. Since the insertion tube 9 can directly penetrate into the bottom of the crack, insufficient bottom filling caused by gravity attenuation when asphalt is poured from the surface is avoided, and the blocking of the upper asphalt to the lower air is reduced. When the asphalt settles after one filling, the filling tube 8 and the insertion tube 9 are heated by the heating wire 30 built into the insertion tube 9. After the insertion tube 9 is inserted into the first solidified asphalt, the old asphalt around the insertion point is softened by heat conduction. At the same time, the insertion tube 9 moves back and forth along the depth direction of the crack. On the one hand, the local structure of the old asphalt is broken by physical disturbance, so that the softened old asphalt forms a loose transition layer. On the other hand, the friction of the insertion tube 9 is used to further disperse the heat and expand the softening range. Then the asphalt is sprayed again for filling to prevent stratification.

[0039] like Figure 4-Figure 5As shown, the driving frame 2 includes a frame plate 21 and a first frame 22 fixed at one end of the frame plate 21. A first motor 23 is fixedly installed inside the first frame 22. The first frame 22 can fix the first motor 23, thereby improving the stability of the first motor 23. A screw 24 is rotatably connected inside the frame plate 21. The screw 24 is fixedly connected to the output end of the first motor 23. The screw 24 can be driven to rotate by the first motor 23. The rotation of the screw 24 can drive the movable seat 4 to move, thereby adjusting the height of the movable seat 4.

[0040] The guide seat 3 includes a vertical plate 31 and a vertical groove 32 opened on one side of the vertical plate 31. The vertical plate 31 is fixedly connected to the frame plate 21. One side of the vertical plate 31 is opened with multiple S-shaped grooves 33, and the multiple S-shaped grooves 33 are connected to each other. A curved path can be formed through the multiple S-shaped grooves 33, which can change the moving trajectory of the movable seat 4. The vertical groove 32 is connected to the S-shaped groove 33. When one end of the telescopic member 5 is inserted into the vertical groove 32, when the movable seat 4 continues to move downward, the movable seat 4 moves left and right due to the limitation of the multiple S-shaped grooves 33.

[0041] The movable seat 4 includes a threaded plate 41 and a rectangular plate 42 fixed on one side of the threaded plate 41. The threaded plate 41 is threadedly connected to the screw rod 24, and the threaded plate 41 is slidably connected to the frame plate 21. A protrusion 43 is slidably connected inside the rectangular plate 42, and a support plate 44 is fixedly installed on one side of the protrusion 43. The screw rod 24 can be driven to rotate by the first motor 23. The rotation of the screw 24 can drive the threaded plate 41 to move, so that the height of the support plate 44 can be adjusted. The support plate 44 contacts the rectangular plate 42. When one end of the telescopic member 5 is inserted into the vertical slot 32, when the threaded plate 41 continues to move downward, the support plate 44 and the protrusion 43 move left and right due to the limitation of the multi-segment S-shaped slot 33, thereby driving the filling tube 8 and the insertion tube 9 to move left and right.

[0042] like Figure 2 and Figure 6-Figure 9 As shown, the telescopic member 5 includes a fixed column 51 and a first disc 52 fixed inside the fixed column 51, an electromagnet 53 is fixedly installed inside the fixed column 51, a connecting rod 54 is slidably connected to one side of the first disc 52, and a roller 55 is rotatably connected to one end of the connecting rod 54. The provision of the roller 55 can reduce the friction between the vertical groove 32 and the S-shaped groove 33, so that the fixed column 51 can move better, a snap ring 56 is fixedly installed on the surface of the connecting rod 54, and the snap ring 56 is slidably engaged with the inner wall of the fixed column 51, two limit rods 57 are fixedly installed on one side of the first disc 52, and the snap rings 56 are slidably connected to the two limit rods 57. The movement of the snap ring 56 can be limited by the two limit rods 57, and the snap ring 56 can be detached from the two limit rods 57. A magnet block 58 is fixedly installed at one end of the connecting rod 54.

[0043] The electromagnet 53 is started by a controller (the controller is prior art and not shown in the figure), and the electromagnet 53 can push the magnet block 58 to move inside the fixed column 51, thereby pushing the connecting rod 54 and the roller 55 to move, so that the roller 55 is inserted into the vertical groove 32. At the same time, the connecting rod 54 drives the snap ring 56 to cancel the engagement with the inner wall of the fixed column 51 until the snap ring 56 contacts the first disc 52 and engages with the fixed column 51 again. Therefore, when the threaded plate 41 continues to move downward, the limiting roller 55 of the multi-segment S-shaped groove 33 moves inside, so that the support plate 44 and the protrusion 43 can be moved left and right, thereby driving the filling tube 8 and the insertion tube 9 to move left and right. Conversely, the roller 55 can be separated from the vertical groove 32 and the S-shaped groove 33.

[0044] Two arc surface grooves 511 are correspondingly provided inside the fixed column 51. The retaining ring 56 includes a second disc 561 and arc surface blocks 562 slidably connected to both sides of the second disc 561. The two arc surface blocks 562 are slidably connected to the two arc surface grooves 511. First springs 563 are fixedly installed inside both sides of the second disc 561. The first springs 563 are fixedly connected to the arc surface blocks 562. When the second disc 561 moves, the arc surface blocks 562 move toward the inside of the second disc 561 due to the limitation of the arc surface groove 511. Then the arc surface blocks 562 and the arc surface groove 511 are misaligned, causing the second disc 561 to continue moving until the arc surface blocks 562 are pushed into the inside of the arc surface groove 511 at another position by the elastic force of the first springs 563, which can fix the second disc 561.

[0045] A connecting pipe 61 is installed on one side of the pump body 6, and the connecting pipe 61 is connected to the filling pipe 8. A telescopic pipe 62 is installed on one side of the pump body 6, and the telescopic pipe 62 is connected to the caulking machine 1. The pump body 6 transports asphalt from the caulking machine 1 to the inside of the filling pipe 8 through the telescopic pipe 62, and plays a connecting role through the connecting pipe 61.

[0046] The driving member 7 includes a second frame 71 and a second motor 72 fixed inside the second frame 71. A first gear 73 is fixedly installed at the output end of the second motor 72. The second frame 71 can fix the second motor 72 to improve the stability of the second motor 72. The second motor 72 can drive the first gear 73 to rotate. The rotation of the first gear 73 can drive the insertion tube 9 to rotate, so that the angle between the insertion tube 9 and the filling tube 8 can be adjusted.

[0047] A second gear 91 is fixedly mounted on one end of the insertion tube 9, and the first gear 73 is meshed with the second gear 91. The controller controls the second motor 72 to drive the first gear 73 to rotate. The rotation of the first gear 73 can drive the second gear 91 to rotate, and the rotation of the second gear 91 can rotate the insertion tube 9. Therefore, the angle between the insertion tube 9 and the filling tube 8 can be adjusted so that the first through hole 10 and the second through hole 20 are misaligned or overlapped with each other.

[0048] In order to solve the technical problems of inconvenient adaptive adjustment according to the crack depth and inconvenient cleaning of the surface of the insertion tube 9, as Figure 9 As shown, the following preferred technical solutions are provided:

[0049] The elastic limit seat 40 includes a sleeve 401 and a movable plate 402 fixed at one end of the sleeve 401. Two sliding rods 403 are fixedly installed on one side of the movable plate 402. The two sliding rods 403 are both slidably connected to the support plate 44. Two second springs 404 are fixedly installed on one side of the movable plate 402. One end of the two second springs 404 is fixedly connected to the support plate 44. The two sliding rods 403 can limit the two second springs 404 to prevent the two second springs 404 from deforming during extrusion. Several universal balls 405 are installed on one side of the movable plate 402.

[0050] The universal ball 405 can reduce the friction between the movable plate 402 and the ground, so that the movable plate 402 can move better. When the insertion tube 9 moves into the crack, the movable plate 402 drives the sleeve 401 to slide upward due to the reaction force of the ground. At this time, the position of the sleeve 401 is directly related to the depth of the crack. When the crack is shallow, the sleeve 401 moves up a short distance, which can block the through hole of the second through hole 20 on the upper part of the insertion tube 9, leaving only the second through hole 20 at the lower position for spraying, to prevent asphalt from overflowing from the shallow part. When the crack is deep, the sleeve 401 moves up a long distance, which makes it inconvenient to block the second through hole 20, so that the asphalt can reach the bottom of the crack directly, and can be adjusted in time according to cracks of different depths. At the same time, when the insertion tube 9 is pulled out upward after the spraying is completed, the elastic force of the second spring 404 pushes the sleeve 401 to return downward, and the inner wall of the sleeve 401 is tightly attached to the surface of the insertion tube 9, forcibly scraping off the adhered asphalt, thereby improving the cleanliness of the surface of the insertion tube 9.
