Description

Technical Field

[0001] This invention relates to the field of highway crack repair technology, and in particular to a highway crack repair device and its usage method. Background Technology

[0002] Road surface cracking is a common road defect, typically manifesting as longitudinal cracks, transverse cracks, and network cracks, requiring timely treatment. Methods for treating road cracks include crack assessment, crack cleaning, crack filling, crack sealing, and crack widening. This article discusses the use of road crack repair devices to repair road surface cracks.

[0003] Highway crack repair machines are mainly used to fill road cracks. Typically, the crack sealant is heated and then pumped into the crack. However, before filling the crack, workers need to clean the crack with cleaning tools. For cracks in wider areas or network cracks, a separate drilling machine is required to excavate or cut the road surface to increase the repair area of ​​the sealant and crack. The repair process involves many steps and tools, and the steps are time-consuming, resulting in a long repair time and affecting road traffic efficiency. Summary of the Invention

[0053] The present invention also provides a method of using a highway crack repair device, including the following specific steps:

[0054] Step 1: Move the repair vehicle to the location of the road crack according to its position, drive the robotic arm to make its heating head horizontal, and set the mounting plate and movable plate in a horizontal structure with the upper and lower parts aligned. Pull down the movable plate, and according to the crack condition, insert the drill rod into the bottom of one of the bearing blocks and the rotating block. Pull up the two pressure rods to push the movable rod upwards, so that the locking block is in a vertical position and fits against the inner wall of the rotating block. Push the drill rod upwards so that the T-shaped block can be pushed into the inner cavity of the cross groove. By releasing the pull on the pressure rod, under the elasticity of the compression spring and the elasticity of the torsion spring, the pull rope drives one end of the adjacent movable rod to pry up. The locking block is set at a right angle to the inner wall of the rotating block, so that the locking block can lock the top of the drill rod.

[0055] Step 2: Loosen the movable plate. Through the elastic recovery of the first tension spring and the relative positions of the cross groove and the bottom of the connecting rod, the connecting rod is inserted and engaged with the inner cavity of the cross groove. The connecting rod presses down on the T-block, and the T-block abuts against the top of the drill rod. Driven by the servo motor, the connecting rod drives the rotating block to rotate, allowing the drill rod to drill and chisel the crack.

[0056] Step 3: After chiseling the crack to the specified area, press down the movable plate, the connecting rod slides out of the inner cavity of the cross groove, pull up the lever so that the bottom of the lever can move the movable rod, the pull rope is pulled, two of the locking blocks push against the T-block and release the limit on the drill rod, at the same time the two locking blocks on the other bearing block release the position limit on the locking rod, so that the locking rod and the drill rod can be swapped. Install the cleaning part into the inner cavity of the rotating block at the bottom of the servo motor, drive the servo motor, so that the brush rod can brush and clean the chiseled crack surface;

[0057] Step 4: Drive the robotic arm to rotate its heating head, and set the crack filling pipe at an angle or perpendicular to the ground. According to the start of the pump at the end of the crack filling adhesive heating box, the sealing adhesive can be injected into the crack and excavated surface through the crack filling pipe for road repair.

[0058] The technical effects and advantages of this invention are as follows:

[0059] (1) The present invention utilizes a combination of a repair vehicle, a robotic arm, a crack filling mechanism, and a cleaning mechanism. Through the setting of the positioning mechanism, the cleaning mechanism can drill holes in the road surface and perform cleaning operations, reducing the consumption of tools. After cleaning, the road surface can be filled with crack filling adhesive through the crack filling mechanism, so that the road surface cracks can be repaired quickly, improving the repair efficiency, reducing the time spent on process connections, and ensuring that it does not affect the normal passage of the road.

[0060] (2) The present invention utilizes the combination of the installation components and the positioning mechanism on the cleaning mechanism. Through the installation components, the connecting rod and the rotating block on the positioning mechanism are easy to install and remove, making it easy to install and replace the drill rod and the cleaning parts. The drill rod and the cleaning parts are stably engaged on the movable plate, which is suitable for the cleaning mechanism to perform stable drilling and cleaning of the road surface, and improves the convenience of the highway crack repair device in use.

[0061] (3) The present invention utilizes the combination of the snap-fit ​​component and the pressure rod on the positioning mechanism. Through the setting of the rotating block, connecting component, bearing block, snap-fit ​​component, support block, pressure rod and through block on the positioning mechanism, it can synchronously move the snap-fit ​​components on both sides of the two bearing blocks by synchronously operating the two pressure rods on both sides of the movable plate. This makes the snap-fit ​​block on the snap-fit ​​component easy to rotate, which is convenient for simultaneous disassembly and assembly of the drill rod and the cleaning part. The setting of the through block is to improve the positional stability of the inverted drill rod and the cleaning part.

[0062] (4) The present invention utilizes the combination of the movable rod and the pull rope on the snap-fit ​​assembly. Through the positioning pin and the compression spring, the movable rod can be set as a pry bar. By moving the movable rod, the pull rope can be pulled. Through the elasticity of the compression spring and the torsion spring, the stability of the position of the movable rod and the snap-fit ​​block is improved, so that the movable rod and the snap-fit ​​block will not rotate arbitrarily.

[0074] This invention provides, for example Figure 1-9The highway crack repair device shown includes a repair vehicle 1, a robotic arm 2, a crack filling mechanism 3, a cleaning mechanism 4, a positioning mechanism 5, and a pressure plate 6. The robotic arm 2 is installed at one end of the repair vehicle 1. The crack filling mechanism 3 is installed at the movable end of the robotic arm 2 and is used to fill the crack with sealant. The cleaning mechanism 4 is installed at the bottom of the crack filling mechanism 3 and is used for excavating concrete and cleaning the repair surface. The positioning mechanism 5 is installed on the cleaning mechanism 4. The pressure plate 6 is installed at one end of the repair vehicle 1 via a hydraulic cylinder. The pressure plate 6 is used to compact the repair surface, and the pressure plate 6 has an inverted T-shaped structure. The back of the pressure plate 6 is fixedly connected to the telescopic end of the hydraulic cylinder. The hydraulic cylinder is fixedly connected to one end of the repair vehicle 1. Driven by the hydraulic cylinder, the pressure plate 6 is pressed down so that it can compact the filled road surface.

[0075] The crack filling mechanism 3 includes a heating head 31 and a crack filling tube 32. The heating head 31 is fixed to the movable end of the robot arm 2, and the crack filling tube 32 is fixed to the discharge end of the heating head 31. The feed end of the heating head 31 is connected to the crack filling adhesive heating box through a heating pipe. The crack filling adhesive heating box is fixed on the repair vehicle 1, and a pump body is installed at the discharge end of the crack filling adhesive heating box. The pump body is connected to the feed end of the heating head 31 through a heating pipe, so that the crack filling adhesive in the crack filling adhesive heating box can enter the inner cavity of the heating head 31 for reheating, and then be discharged through the crack filling tube 32. Through the movement of the robot arm 2, the crack filling tube 32 can be tilted downward or vertically to perform adhesive filling treatment on the cracks in the road surface.

[0076] In addition, the cleaning mechanism 4 includes a mounting component 41, a connecting hole 42, a servo motor 43, a connecting rod 44, a drill rod 45, and a cleaning component 46. The mounting component 41 is mounted on the bottom of the heating head 31, the connecting hole 42 is opened at the end of the mounting component 41, the servo motor 43 is mounted on one end of the mounting component 41, and the servo motor 43 is electrically connected to an external power supply through an external switch. The connecting rod 44 is connected to the output end of the servo motor 43, so that the drive of the servo motor 43 can drive the connecting rod 44 to rotate stably. The bottom of the connecting rod 44 has a cross-shaped structure. The drill rod 45 is connected to the connecting rod 44 through a positioning mechanism 5. The drill rod 45 is used for chiseling at cracks, which is convenient for chiseling cracks in excessively wide areas or around sewers, expanding the repair area, increasing the contact area between the sealant and the repair area, and improving the repair stability of the repair area. The cleaning component 46 and the drill rod 45 are alternately installed below the servo motor 43. The cleaning component 46 is used for cleaning inside the cracks.

[0077] Specifically, the mounting assembly 41 includes a mounting plate 411, a first tension spring 412, a limiting post 413, and a movable plate 414. The mounting plate 411 is fixed to the bottom of the heating head 31, the servo motor 43 is fixed to one end of the mounting plate 411, the first tension spring 412 is fixed to the bottom of the mounting plate 411, the limiting post 413 is fixed to the middle of the mounting plate 411 and is sleeved in the inner cavity of the first tension spring 412, the movable plate 414 is fixed to the bottom of the first tension spring 412, the limiting post 413 is slidably inserted into the middle of the movable plate 414, and the connecting hole 42 is opened at the end of the movable plate 414. By pulling the movable plate 414, the first tension spring 412 is stretched, which makes it easier for the connecting rod 44 installed at the output end of the servo motor 43 to move away from the movable plate 414.

[0078] More specifically, the cleaning component 46 includes a fixing block 461, a locking rod 462, and a brush rod 463. The fixing block 461 has a cylindrical structure, and an annular groove is provided on the outer wall of the fixing block 461. The locking rod 462 is fixed to one end of the fixing block 461. The top of the locking rod 462 has the same T-shaped cylindrical structure as the top of the drill rod 45, which facilitates the positioning mechanism 5 to position the locking rod 462 and the drill rod 45 respectively. Multiple brush rods 463 are rotatably interlocked with the other end of the fixing block 461 through bearings. The brush rods 463 are composed of elastic steel wire and bristles, which gives the brush rods 463 a certain elasticity when in use, so that the brush rods 463 can brush the uneven inner wall of the crack, reduce the dust on the inner wall of the crack, and improve the adhesion performance of the potting compound to the inner wall of the crack.

[0079] Furthermore, the positioning mechanism 5 is mounted on the movable plate 414. The positioning mechanism 5 includes a rotating block 51, a connecting component 52, a bearing block 53, a snap-fit ​​component 54, a support block 55, a pressure rod 56, and an inserting block 57. The rotating block 51 is inserted into the inner cavity of one of the connecting holes 42 via a bearing. The connecting component 52 is installed in the middle of the rotating block 51. The connecting rod 44 is connected to the rotating block 51 via the connecting component 52. The bearing block 53 is fixed to the bottom of the connecting hole 42. Two snap-fit ​​components 54 are arranged on both sides of the same bearing block 53. Multiple support blocks 55 are respectively fixed to both sides of the upper surface of the movable plate 414. The pressure rod 56 is located on both sides of the movable plate 414. The pressure rod 56 is movably engaged with the top of the support block 55, which facilitates the support block 55 to stably engage the pressure rod 56. The bottom end of the pressure rod 56 is slidably connected to a limit rod, which is fixedly connected to the lower surface of the movable plate 414. Through the limit rod, the pressure rod 56 can only slide in the up and down direction. The insertion block 57 is installed at one end of the engagement assembly 54. The insertion block 57 is fixed by two L-shaped rods and a C-shaped block, which facilitates the insertion of the brush rod 463 through the gap formed between the insertion block 57 and the pressure rod 56, thereby improving the stability of the position of the brush rod 463.

[0080] Specifically, the connecting assembly 52 includes a cross groove 521, a second tension spring 522, and a T-block 523. The cross groove 521 is located at the top of the rotating block 51. The bottom of the connecting rod 44 is inserted into the inner cavity of the cross groove 521, so that when the connecting rod 44 is inserted into the cross groove 521, the rotation of the connecting rod 44 can drive the rotating block 51 to rotate stably. The second tension spring 522 is fixed to the top of the inner wall of the rotating block 51, and the T-block 523 is inserted into the rotating block 51. In the middle of 1, the bottom of the T-block 523 is fixedly connected to the bottom end of the second tension spring 522. The T-block 523 is used to press against the drill rod 45 and the clamping rod 462. When the connecting rod 44 is inserted into the cross groove 521, the connecting rod 44 presses down on the T-block 523, causing the second tension spring 522 to be stretched. The bottom of the T-block 523 presses down on the drill rod 45 or the clamping rod 462, so that the clamping assembly 54 can stably clamp the drill rod 45 or the clamping rod 462.

[0081] More specifically, the snap-fit ​​assembly 54 includes a movable rod 541, a positioning pin 542, a compression spring 543, a pull rope 544, a rotating column 545, a locking block 546, and a torsion spring 547. Two adjacent movable rods 541 are rotatably connected to both sides of the bearing block 53. Movable grooves are provided on both sides of the bearing block 53. The movable rod 541 is rotatably connected to the inner cavity of the movable groove. The positioning pin 542 is rotatably connected to the end of the movable rod 541 and is fixedly connected to the inner wall of the adjacent bearing block 53, i.e., the positioning pin 542 is fixedly connected to the inner wall of the movable groove. The compression spring 543 is fixed between the end of the movable rod 541 and the inner wall of the bearing block 53, and the inner cavity of the compression spring 543 is fitted with... An arc rod is provided, which is slidably inserted into one end of the movable rod 541. Both ends of the arc rod are fixed to the inner wall of the movable groove. The arc rod improves the stability of the compression spring 543. A pull rope 544 is fixed to the end of the movable rod 541 and is slidably inserted into the top of the bearing block 53. A rotating column 545 is rotatably inserted into the bottom of the rotating block 51. A locking block 546 is fixed to the middle of the rotating column 545. The pull rope 544 is fixed to one side of the locking block 546 by a fixing nail. The pull rope 544 is coiled and fitted to the outer wall of the rotating column 545. The locking block 546 is used to engage the drill rod 45 and the locking rod 462. A torsion spring 547 is fixed to one end of the rotating column 545. The other end of 7 is fixedly connected to the bottom of the rotating block 51 via a clamping plate. The elasticity of the torsion spring 547 allows the clamping block 546 to remain at a right angle to the inner wall of the rotating block 51 for an extended period. This facilitates the clamping block 546 engaging one end of the drill rod 45 or one end of the clamping rod 462. After the connecting rod 44 slides out of the cross groove 521, prying up the movable rod 541 pulls the pull rope 544, compresses the compression spring 543, and twists the torsion spring 547. This allows the clamping block 546 to lift the drill rod 45 or the clamping rod 462 and retract into the inner cavity of the rotating block 51, ensuring that the clamping block 546 does not interfere with the drill rod 45 or the clamping rod 462 on the bearing block. The drill rod 45 can be inserted and removed from the inner cavity of 53. When the drill rod 45 is in use, the cleaning component 46 can be set in an inverted state with the brush rod 463 facing upwards, so that the cleaning component 46 does not interfere with the use of the drill rod 45. Similarly, when the cleaning component 46 is in use, the drill rod 45 can be installed inverted in the inner cavity of another connecting hole 42 below the non-servo motor 43. The pressure rod 56 is set below the two movable rods 541 on the same side, and the insertion block 57 is inserted and connected to one end of the pressure rod 56. Both insertion blocks 57 are used for the insertion and locking of the brush rod 463, and the opposite end of the two insertion blocks 57 can fit and lock against the outer wall of the drill rod 45, improving the positional stability of the drill rod 45 or the cleaning component 46 when not in use.

[0082] How to use this invention:

[0083] According to the location of the road crack, the repair vehicle 1 is moved to the crack location, and the manipulator 2 is driven to make its heating head 31 horizontal, so that its mounting plate 411 and movable plate 414 are set in a horizontal structure with the upper and lower parts aligned. The movable plate 414 is pulled down, and the drill rod 45 is inserted and connected to one of the bearing blocks 53 and the bottom of the rotating block 51 according to the crack condition. The two pressure rods 56 are pulled up, so that they push the movable rod 541 upward. The locking block 546 is in a vertical state and fits against the inner wall of the rotating block 51, and pushes the drill rod 45 upward, so that its T-shaped block 523 can push into the inner cavity of the cross groove 521. By releasing the pull on the pressure rod 56, under the elasticity recovery of the pressure spring 543 and the torsion spring 547, the pull rope 544 drives one end of the adjacent movable rod 541 to be pried up. The locking block 546 is set at a right angle to the inner wall of the rotating block 51, so that the locking block 546 can lock the top of the drill rod 45.

[0084] Release the movable plate 414, and through the elastic recovery of the first tension spring 412 and the relative positions of the cross groove 521 and the bottom of the connecting rod 44, the connecting rod 44 is inserted and engaged with the inner cavity of the cross groove 521, and the connecting rod 44 presses down on the T-block 523, and the T-block 523 abuts against the top of the drill rod 45. Driven by the servo motor 43, the connecting rod 44 drives the rotating block 51 to rotate, so that the drill rod 45 can drill and chisel at the crack.

[0085] After the crack is excavated to the specified area, the movable plate 414 is pressed down, the connecting rod 44 slides out of the inner cavity of the cross groove 521, and the pressure rod 56 is pulled up so that the bottom of the pressure rod 56 can move the movable rod 541. The pull rope 544 is pulled, and two locking blocks 546 push against the T-shaped block 523 and release the restriction on the drill rod 45. At the same time, two locking blocks 546 on another bearing block 53 release the position restriction on the locking rod 462, so that the locking rod 462 and the drill rod 45 can be swapped. The cleaning component 46 is installed in the inner cavity of the rotating block 51 at the bottom of the servo motor 43, and the servo motor 43 is driven so that the brush rod 463 can brush and clean the excavated crack surface.

[0086] Drive the robotic arm 2 to rotate its heating head 31, and set the crack filling pipe 32 at an angle or perpendicular to the ground. According to the start of the pump body at the end of the crack filling adhesive heating box, the sealing adhesive can be injected into the crack and the excavated surface through the crack filling pipe 32 to repair the road.
