[0007] Preferably, the grooving process includes setting up a special grooving platform in the prefabrication yard, measuring the width of the non-grooving area close to the road panel to be paved on site, fixing the channel steel on the grooving platform as a ruler, determining the starting point of grooving the road panel to be paved, grooving with the aid of the ruler, and then moving the ruler to complete the grooving of the entire road panel in sequence, so that the grooving module is aligned with the adjacent road panel.

[0008] Preferably, the installation of new prefabricated road panels includes, in sequence, cleaning the bottom of the road panel, installing lifting rings and slings, placing plate seam control fixtures, using manual labor and cranes to lift the newly prefabricated qualified road panel to the position where the road panel needs to be replaced, checking and adjusting the amount of misalignment between the newly replaced road panel and the surrounding road panels to meet the requirements, grouting the double-mother plate seams between the road panels in order from low to high, and sealing the seams with silicone sealant.

[0011] Preferably, the vehicle body is fixedly connected with a detection box, the detection box is slidably connected to a slider that moves in a vertical direction, and the slider is connected to the detection box via a tension spring.

[0012] Preferably, a push switch capable of controlling the operation of the travel motor is connected to the upper end of the detection box. In an initial state, the elastic force of the tension spring causes the slider to press the push switch, and the travel motor is powered on and operates.

[0016] 2. In the crushing mechanism proposed by the present invention, when the toothless gear drives the hammer handle to descend, the hammer handle drives the slider to move through the push rod. At this time, the slider no longer presses the push switch, the travel motor is powered off, and the power wheel no longer rotates. At this time, crushing work can be carried out. When the crushing reaches a certain degree, the distance that the hammer handle descends can make the induction head move to the side of the proximity switch, and the electromagnet is energized to release the limit on the slider by the block, and the tension spring pulls the slider to reset, so that the push switch is pressed and the vehicle moves again. Through the above arrangement, the vehicle body no longer moves during crushing, and will continue to move only when the crushing requirements are met. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] like Figure 1 As shown, this embodiment proposes a technical method for rapid recovery of assembled track functions, comprising the following steps: S1: According to the severity of the damage to the road slab, determine the range of the road slab that needs to be replaced, and use the crushing mechanism to crush the old road slab; S2: Roughen the side of the old road surface and set an elevation strip on the top surface of the slab base of the road surface to be replaced; S3: Clean the old road panel base and restore the damaged leveling layer; S4: groove the pavement panel surface and install the new prefabricated pavement panel; S5: Grouting is performed on the joints of the road slabs, and then the joints of the road slabs are sealed.

[0021] Clean up the damaged flying debris: use loaders and excavators to clean up the damaged area and the surrounding flying debris, and remove the unusable materials to a nearby pile outside the runway.

[0022] The removal of the old road panels includes removing the connectors between the panels and removing the bolt-plate connectors between the road panels to be replaced and the surrounding retained road panels. First, a wrench is used to remove the fixing bolts at both ends of the bolt-plate connector, and then the bolt plates of the bolt-plate connectors are removed.

[0023] Cut the board seams around the old road panels, and use a cutting machine to cut off the board seams between the road panels that need to be replaced and the surrounding retained road panels. The cutting machine uses a 800mm diameter thickened alloy saw blade (maximum cutting depth 33cm), which can be used for reinforced concrete cutting. In order to speed up the construction progress, 4 working surfaces can be constructed simultaneously on the board seams around.

[0024] The hydraulic static blasting method is used to dismantle the road panels to be replaced. Based on the old road panels broken by the crushing mechanism, a water-grinding drill is used to take cores along the road panel (cracks) to form a suspended surface. Then, a water-grinding drill is used in conjunction with multiple hydraulic rock splitters to achieve hydraulic static blasting, and the road panels are broken down into small pieces for removal.

[0025] The side of the old road panel is roughened with a self-propelled vertical surface roughening machine. During construction, attention should be paid to protecting the concrete surface within 3 cm below the top of the panel. The side of the new prefabricated road panel is roughened in advance, and only the surface of the old road panel is roughened on site, and multiple working surfaces are operated simultaneously.

[0026] The elevation belt is installed on the top surface of the slab base of the pavement to be replaced to reduce the workload of fine-tuning in the later stage. The elevation belt is made of steel plate + rubber gasket. The thickness of the elevation belt = the top surface elevation of the adjacent runway pavement - the top surface elevation of the leveling layer - the thickness of the prefabricated pavement panel.

[0027] Base cleaning, cleaning of the old road panel top plate, including the isolation layer material applied locally. Large pieces of material are cleaned manually, and small particles are cleaned with a vacuum cleaner.

[0028] Restore the leveling layer, remove the grouting materials in the surrounding retained road panel mother mouth, and when the existing leveling layer is partially damaged, use dry hard mortar to restore it. The restored surface should be flush with the top surface of the surrounding leveling layer, and reserve 5~10mm of settlement.

[0029] The grooving process includes setting up a special grooving platform in the prefabrication yard, measuring the width of the non-grooving area close to the pavement panel on site, fixing the channel steel on the grooving platform as a ruler, determining the starting point of grooving the pavement panel, using the ruler to assist in grooving, and then moving the ruler to complete the grooving of the entire pavement panel in sequence so that the grooving module is aligned with the adjacent pavement panel.

[0030] The installation work of new prefabricated road panels includes, in sequence, cleaning the bottom of the road panel, installing lifting rings and slings, placing panel seam control fixtures, using manual labor and cranes to lift the newly prefabricated qualified road panel to the position where the road panel needs to be replaced, and checking and adjusting to ensure that the misalignment between the newly replaced road panel and the surrounding road panels meets the requirements.

[0031] The grouting of the joints of the road panels and the double-mother joints between the road panels are constructed in the order from low to high, and the cross holes of the corners of the road panels around are used as grouting holes. For the sealing of the road panels, first clean the joints, then install the backing strips, and finally use silicone sealant to seal the joints.

[0032] The crushing mechanism includes a body 1, the body 1 is fixedly connected with a sliding sleeve 12, the sliding sleeve 12 is slidably connected with a hammer handle 9 that moves in the vertical direction, the hammer handle 9 is detachably connected with a hammer head 10, and the hammer head 10 is fixedly connected with a plurality of crushing nails 11. Through the cooperation of the hammer head 10 and the crushing nails 11, the ground can be better crushed. In order to better facilitate the descent of the hammer handle 9, the hammer handle 9 can also be connected to the body 1 through a reset spring. When the hammer handle 9 rises, the reset spring is compressed.

[0033] The vehicle body 1 is rotatably connected to a toothless gear 7, and a rack 8 is fixedly connected to one side of a hammer handle 9. The rack 8 and the toothless gear 7 are meshed with each other. The vehicle body 1 is connected to a motor for driving the toothless gear 7 to rotate. The motor and the vehicle body 1 are fixedly connected. The toothless gear 7 is fixedly sleeved on the output shaft of the motor. The motor drives the toothless gear 7 to rotate, and the toothless gear 7 can drive the hammer handle 9 to rise. When the toothless gear 7 and the rack 8 are disengaged, the hammer handle 9 drops under the action of gravity and a return spring.

[0034] The vehicle body 1 is fixedly connected to a collecting box 4, and the collecting box 4 is fixedly connected to an air pump 5. The air pump 5 includes an air suction pipe 6 and a discharge pipe. The discharge pipe and the collecting box 4 are connected. The air suction pipe 6 is located on one side of the hammer head 10. The fine particles crushed by the hammer head 10 can be sucked into the collecting box 4 for collection. The box body 1 is also rotatably connected to a box door 3, and the box door 3 can be opened to facilitate maintenance of the structure inside the vehicle body 1.

[0035] The vehicle body 1 is rotatably connected to a plurality of power wheels 2, and the vehicle body 1 is connected to a travel motor 22 for driving the power wheels 2 to rotate. The travel motor 22 is fixedly connected to the vehicle body 1, and the vehicle body 1 is rotatably connected to a power shaft, and the power wheels 2 are fixedly sleeved on the power shaft. The travel motor 22 is connected to the power shaft. When the travel motor 22 works, it can drive the power wheels 2 to rotate, thereby realizing the movement of the vehicle body 1.

[0036] The vehicle body 1 is fixedly connected with a detection box 16, and the detection box 16 is fixedly connected with a guide rod 17 arranged in the vertical direction. The guide rod 17 is slidably connected with a slider 20 moving in the vertical direction. The slider 20 is connected to the detection box 16 through a tension spring 18. The tension spring 18 is sleeved on the guide rod 17. The upper end of the tension spring 18 is connected to the detection box 16, and the lower end of the tension spring 18 is connected to the slider 20.

[0037] The upper end of the detection box 16 is connected to a push switch 15 that can control the operation of the travel motor 22. In the initial state, the elastic force of the tension spring 18 causes the slider 20 to press the push switch 15, and the travel motor 22 is powered on.

[0038] The push switch 15 is specifically a push spring switch, which is usually composed of a push button, a spring, a fixing seat and a conductive contact. The push button is usually made of plastic or metal and has a certain pressing performance and mechanical strength. The function of the spring is to allow the button to automatically reset and ensure the elasticity of the press. The fixing seat is used to fix the button and the spring to ensure that their positions do not change. The conductive contact is the key part of the connection circuit. By pressing the button, the contact is connected or disconnected to realize the function of the switch.

[0039] When the slider 20 contacts the button, the button is pressed, and the button applies force to the inside to compress the spring. During the button pressing process, the conductive contact contacts another contact, so that the circuit is closed, the current passes, the travel motor 22 works, the power wheel 2 rotates, and the vehicle body 1 moves. When the button is released, the elastic action of the spring restores the button to its original position, the conductive contact separates from the other contact, the circuit is disconnected, the current stops flowing, and the travel motor 22 stops working. In this way, the on-off control of the circuit can be achieved by pressing the button.

[0040] The slider 20 is provided with a slot, and the lower end of the detection box 16 is slidably connected with a block 21 that can slide into the slot. The block 21 is connected to the detection box 16 through a spring. The spring is sleeved on the block 21, one end of the spring is connected to the block 21, and the other end of the spring is connected to the detection box 16. The elastic force of the spring can make the block 21 slide into the slot. The upper surface of the block 21 is an inclined surface, so that the block 21 can slide into the slot 21 easily.

[0041] The detection box 16 is connected to an electromagnet 23 that has an attraction effect on the card block 21. The electromagnet 23 is located on one side of the card block 21, and the magnetic force of the electromagnet 23 is greater than the elastic force of the spring. Therefore, when the electromagnet 23 is energized, the electromagnet 23 attracts the card block 21 to move, and the magnetic force of the electromagnet 23 can make the card block 21 slide out of the slot.

[0042] The hammer handle 9 is connected to a push rod 13 through a compression spring. The push rod 13 is located above the slider 20. The elastic force of the compression spring is much greater than the elastic force of the tension spring 18. When the hammer handle 9 drives the push rod 13 to descend, the push rod 13 drives the slider 20 to descend, causing the tension spring 18 to deform. At this time, the compression spring is only not compressed or only compressed a short distance. At this time, the card block 21 slides into the card slot to limit the slider 20.

[0043] The slider 20 is connected to a proximity switch 19 for controlling the operation of the electromagnet 23. The proximity switch 19 can also control the motor to stop working. The hammer handle 9 is connected to a sensing head 14 that cooperates with the proximity switch 19. The sensing head 14 can be detachably connected to the hammer handle 9 by means of bolts. The crushing depth can be adjusted by adjusting the height position of the sensing head 14.

[0044] As the hammer handle 9 descends, when the hammer handle 9 descends deep enough, the compression spring is compressed to a certain range, and the induction head 14 will move to the side of the proximity switch 19, indicating that the crushing depth is sufficient at this time. The induction head 14 cooperates with the proximity switch 19, and the proximity switch 19 controls the electromagnet 23 to energize, so that the slider 20 is reset, and the motor stops at the same time, and no crushing is performed. At this time, the travel motor 22 is energized to make the vehicle body 1 move.

[0045] The proximity switch 19, the electromagnet 23, the motor and the travel motor 22 are connected to a controller. The proximity switch is a position switch that can be operated without direct mechanical contact with the moving parts. When the induction head 14 measures the sensing surface of the proximity switch to the action distance, the switch can be operated without mechanical contact or any pressure, thereby providing a control instruction to the controller, and the controller controls the electromagnet 23 to be energized, the motor stops, and no crushing is performed. Through the above settings, it is achieved that when crushing, the vehicle body 1 will no longer move, and will only continue to move when the crushing requirements are met.

[0046] The method of using the crushing mechanism comprises the following steps: The motor drives the toothless gear 7 to rotate, and the toothless gear 7 drives the hammer handle 9 to rise. When the toothless gear 7 and the rack 8 are out of mesh, the hammer handle 9 drives the hammer head 10 to descend to break the road panel. At the same time, the hammer handle 9 drives the push rod 13 to move, and the push rod 13 pushes the slider 20 to descend, so that the tension spring 18 is stretched, and finally the block 21 slides into the slot to limit the position of the slider 20. As the hammer handle 9 drives the hammer head 10 to reciprocate, the road panel is further crushed. When the crushing depth reaches the specified depth, the induction head 14 moves to the side of the proximity switch 19. After the proximity switch 19 detects the signal, the electromagnet 23 is controlled to be energized. The electromagnet 23 has an attraction effect on the block 21, so that the block 21 moves out of the slot, and the limit of the slider 20 is released. Afterwards, under the elastic force of the compression spring 18 , the slider 20 is reset, and the slider 20 presses the push switch 15 , and the push switch 15 controls the travel motor 22 to be energized, and the travel motor 22 controls the power wheel 2 to rotate, so that the vehicle body 1 can travel.

[0047] After the proximity switch 19 detects a signal, the proximity switch 19 controls the motor to move for T time, and then the motor stops moving. The T time can ensure that the toothless gear 7 and the rack 8 are re-engaged, and the hammer handle 9 can be moved to the initial position. The slider 20 is reset under the elastic force of the tension spring 18, which makes it convenient for the motor to drive the hammer handle 9 to rise and make the hammer head 10 leave the ground, thereby preventing the hammer head 10 from affecting the normal walking of the vehicle body 1.

[0048] The present application proposes a technical method for rapid functional restoration of prefabricated road surfaces, including cutting and dismantling of old road panels, simultaneous operation of multiple working surfaces, shortening the time for removing road panels, and using static blasting to dismantle old road panels to minimize the impact on surrounding road panels. Dry-operation method is used to construct an isolation layer to effectively avoid the equal-intensity time of wet-operation method construction, and special grouting materials are used to fill the board seams and double-mother tongue-and-groove joints to ensure the force transmission effect between the boards. This method is well suitable for emergency repair construction of prefabricated road surfaces with more than a single board.
