Description

Technical Field

[0001] This invention relates to the field of vibration and noise reduction technology for urban rail transit, specifically to a rapid inspection and maintenance equipment and method for steel spring floating slab shear hinges. Background Technology

[0002] Steel spring floating slab track technology, with its excellent vibration reduction performance and structural stability, is widely used in newly constructed rail transit lines, becoming the preferred measure for vibration and noise reduction in new rail transit lines near or under sensitive areas such as residential areas, schools, and hospitals. Considering factors such as stress rationality, construction convenience, and economy, expansion joints are usually required between the slabs of steel spring floating slab tracks. For cast-in-place floating slabs, these joints are typically spaced 25m apart, while for precast floating slabs, they are typically spaced 3.6-6m apart. To ensure the integrity and continuity of the track and to coordinate the relative displacement differences between the floating slabs, shear hinges are usually installed at the slab joints. These shear hinges can share some of the shear force borne by the rails at the joints. Cast-in-place floating slabs typically use built-in shear hinges, connected and fixed to the track bed reinforcement cage, and are integrally formed with the track bed through concrete pouring, making construction convenient.

[0003] However, due to the narrow gaps between the panels, typically 30-50mm, and the fact that the built-in shear hinges are embedded in the middle of the floating slab's thickness, with a sealing strip covering the gaps to prevent debris from falling in and affecting the slab's vibration damping effect, routine inspections make it difficult to observe their working condition, damage, and corrosion from the outside. Furthermore, once defects are discovered, repair and replacement are not easy. A typical maintenance window takes 1-3 hours, making it extremely difficult to complete the entire process of detecting and replacing shear hinge defects within such a short timeframe. Summary of the Invention

A pulley capable of longitudinal movement along a steel rail is installed below the main frame, and a lateral moving mechanism capable of transverse movement along the steel rail is slidably installed above the main frame. The fixing and locking component is installed below the main frame and is used to fix the main frame to the steel rail. The positioning platform and the drilling device are installed on the lateral moving mechanism, and the positioning platform and the drilling device cooperate to position the drilling. The inspection device and the rebar detection device are also installed on the lateral moving mechanism. The inspection device is used to extend into the slab joint and inspect the working status of the built-in shear hinge, and the rebar detection device is used to detect the position and depth of the rebars within the floating slab to avoid drilling operations on the rebars.

[0008] Preferably, the lateral movement mechanism includes a lateral guide rail, a slider, and a support base. The slider is formed below the support base and is slidably connected to the lateral guide rail. The extension direction of the lateral guide rail is perpendicular to the extension direction of the rail.

[0010] In a further preferred embodiment, the positioning platform is provided with positioning holes that match the position and number of the upper shear hinge fixing holes.

[0011] In a further preferred embodiment, the drilling device includes at least a plurality of drilling bits, a lifting push rod, and a power device.

The lifting push rod is used to drive the drilling bits to move up and down.

[0012] In a further preferred embodiment, the examination device is a multi-lens endoscope.

[0013] In a further preferred embodiment, the drilling bit of the drilling device can be replaced with a torque wrench, and the power device can drive the torque wrench to fix the upper shear hinge according to a set torque value.

[0018] S4. Secure the steel spring floating plate shear hinge quick maintenance equipment to the rail using the fixing locking device;

[0019] S5. Avoid the reinforced concrete and pre-set an installation area for a set of top-mounted shear hinges on the floating slab using a positioning platform;

[0020] S6. Drill holes in the pre-set installation area of ​​the floating plate using a drilling device and a positioning platform;

[0021] S7. After drilling, clean the concrete inside the borehole and grind the relatively higher floating plate according to the height difference between two adjacent floating plates. After grinding, the thickness of the floating plate meets the predetermined value of the minimum reinforcement protective layer, or add pads to the relatively lower floating plate so that the top surfaces of the two adjacent floating plates are level.

[0022] S8. Inject anchoring adhesive into the borehole and insert the casing or screw, and let it stand until the adhesive reaches the set strength.

[0023] S9. Place an upper shear hinge on two adjacent floating plates, replace the drilling bit of the drilling equipment with a torque wrench, and tighten the road spike or threaded sleeve that matches the sleeve or screw according to the set torque value, so that the upper shear hinge is fixed on the two adjacent floating plates.

[0024] S10. Move the positioning platform, drilling equipment, inspection equipment and rebar detection equipment to the installation position of the next set of upper shear hinges by means of the lateral moving mechanism. Repeat steps S5 to S9.

[0025] Preferably, before step S9, the following steps are also included: analyzing the cause of damage or breakage of the built-in shear hinge; if the misalignment of adjacent floating slabs is caused by tunnel settlement, foundation crushing, or spring breakage, the floating slabs and track status are adjusted before proceeding with subsequent operations.

[0026] In a further preferred embodiment, after step S10, the following steps are also included: checking the stress state of all upper shear hinges; if there is additional shear force due to track irregularities, the error is eliminated by adjusting the thickness of the shims in the vibration isolator, the shims below the upper shear hinges, or the fastener shims.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 3 Figure 6A rapid inspection and maintenance device for floating slab shear hinges includes a main frame 1, a fixing and locking component 2, a positioning platform 3, a drilling device 4, an inspection device 5, and a rebar detection device 6.

[0039] The main frame 1 provides installation space for all other components and integrates them into a single unit for easy handling and movement. To ensure the main frame 1 has sufficient load-bearing capacity, it can be constructed using a metal frame structure. Multiple pulleys are installed below the main frame 1, rolling in contact with the top surface of the rail 8, allowing the entire maintenance equipment to move longitudinally along the rail 8. A lateral movement mechanism is slidably mounted above the main frame 1, enabling the working components mounted on it to translate in a direction perpendicular to the rail 8. In this embodiment, the lateral movement mechanism includes a lateral guide rail, a slider, and a support base. The lateral guide rail is fixedly mounted on the upper surface of the main frame 1, extending perpendicularly to the extension direction of the rail 8. The slider is fixedly mounted on the lower surface of the support base, sliding in contact with the lateral guide rail, allowing the support base to slide smoothly along the lateral guide rail. The support base can be used to mount the positioning platform 3, drilling equipment 4, inspection equipment 5, and rebar detection equipment 6, and can move these components accordingly.

[0040] The fixing and locking component 2 is installed below the main frame 1 and located inside or outside the pulley. The fixing and locking component 2 is used to securely fix the entire maintenance equipment to the rail 8 during drilling operations. The fixing and locking component 2 can employ a friction braking structure or a magnetic braking structure. For example, the friction braking structure can use an electric cylinder-driven gripper structure, which can clamp the rail web of the rail 8 or lock it at the rail head, achieving braking through the frictional force generated by squeezing the rail 8. The magnetic braking structure includes a magnetic structure, a mounting base, and a coil. After being energized, the magnetic structure generates a strong magnetic force, attracting the rail to the side or top surface of the rail 8, achieving stable braking.

[0041] The positioning platform 3 is installed and fixed on the support base and located below the drilling device 4. The positioning platform 3 is used to position the drilling position on the floating plate 7. In this embodiment, the positioning platform 3 can adopt a plate-shaped tooling structure, and positioning holes matching the position and number of fixing holes of the upper shear hinge 10 are opened on its surface.

[0042] The drilling device 4 is used to drill mounting holes for the upper shear hinge 10 on the floating slab 7, or to drill holes to remove damaged pre-embedded sleeves of the upper shear hinge 10. The drilling device 4 includes at least several drilling bits, a lifting push rod, and a power unit. The power unit can be a servo motor, connected to multiple drilling bits via a gear transmission mechanism, allowing simultaneous rotation of at least two drilling bits to achieve multi-hole drilling. The lifting push rod can be a hydraulic or electric lifting device, its output end connected to the mounting base of the power unit, used to drive the power unit and drilling bits to move up and down, achieving drilling operations. The drilling bits of the drilling device 4 can also be removed and replaced with torque wrenches. The power unit can drive the torque wrench to rotate according to a set torque value, achieving automated tightening of fasteners when fixing the upper shear hinge 10. Tightening can be done diagonally and in stages to ensure uniform force on each fastener and improve installation quality.

[0043] The maximum external dimension of the part of the inspection device 5 used for detection is no greater than the width of the gap 11 in the floating plate 7, so that it can extend into the interior of the gap 11. The inspection device 5 can be a multi-lens endoscope with self-illumination and high-definition photography and video recording functions. The inspection device 5 transmits images of the interior of the gap 11 in real time, allowing operators to clearly observe the surface condition of the built-in shear hinge 14, promptly detect defects such as cracks, fractures, and corrosion, and observe the built-in shear hinge 14 from multiple angles. It is understood that other existing devices that can facilitate clear observation of the surface condition of the built-in shear hinge 14 can be used to replace the multi-lens endoscope.

[0044] The rebar detection device 6 is used to detect the position and depth of the rebar within the floating slab 7 before drilling. Due to the dense distribution and small spacing of the rebar in the floating slab 7, and the significant positional errors of the rebar during cast-in-place construction, failure to detect rebar in advance can easily damage the main rebar of the floating slab 7 during drilling, affecting structural safety. The rebar detection device 6 can assist in marking the position of the rebar, guiding operators to avoid drilling and ensuring construction safety. The rebar detection device 6 can employ an electromagnetic induction rebar scanner, with a built-in excitation transmitting coil and detection receiving coil in the instrument probe. The transmitting coil emits an alternating electromagnetic field of a specific frequency into the concrete of the floating slab 7. When the electromagnetic field encounters the rebar, which is a ferromagnetic conductor, eddy currents are induced on the surface of the rebar. These eddy currents radiate a secondary electromagnetic field in the opposite direction. The receiving coil captures the intensity and phase change signals of the secondary electromagnetic field. After amplification, filtering, and algorithmic calculation by the host, the planar position, embedment depth (protective layer thickness), diameter, and distribution direction of the rebar can be accurately output. This allows for rapid rebar detection and marking of avoidance areas before drilling, effectively preventing damage to the main rebar of the floating slab during drilling operations.

[0045] The specific steps for the rapid maintenance method of the steel spring floating plate shear hinge using the above-mentioned maintenance equipment are as follows:

[0046] S1. The operator moves the steel spring floating plate shear hinge rapid repair equipment to the side of the track, places the pulley on the top surface of the steel rail 8, and pushes the equipment longitudinally along the steel rail 8 to the plate joint 11 between the two floating plates 7 that need to be repaired.

[0047] S2. Use tools to remove the fixing bolts of the sealing strip 13 above the joint 11, remove the sealing strip 13, and expose the joint 11. Insert the probe of the inspection device 5 into the joint 11 and check the surface condition of each set of built-in shear hinges 14 in turn through the display screen of the inspection device 5. Each joint 11 is usually equipped with 4 sets of built-in shear hinges 14. If any set of built-in shear hinges 14 is found to have surface cracks, breaks, or severe corrosion, then replacement work should be prepared.

[0048] S3. Start the rebar detection device 6 to scan and detect the drilling area where the upper shear hinge 10 needs to be installed, accurately mark the position and depth of the main rebar in the floating plate 7, and avoid damaging the rebar when drilling.

[0049] S4. Start the fixing and locking component 2. If a friction braking structure is used, control the electric cylinder to drive the gripper to clamp the rail web of the rail 8. If a magnetic braking structure is used, energize the coil so that the magnetic structure is attracted to the rail 8, and firmly fix the entire maintenance equipment to prevent displacement during the drilling process.

[0050] S5. Adjust the lateral position of the support base through the lateral moving mechanism so that the positioning platform 3 is aligned with the installation area of ​​the first set of upper-mounted shear hinges 10.

[0051] S6. Start the power unit and lifting push rod of the drilling equipment 4 to drive the drilling bit to rotate and move downward, drilling the installation hole at the predetermined position. During the drilling process, strictly control the hole diameter, depth, and perpendicularity. The hole diameter should be larger than the outer diameter of the sleeve or screw 12 to be implanted, and the depth should meet the design requirements. If the power unit can drive multiple drill bits to work simultaneously, multiple installation holes can be drilled at once, improving efficiency.

[0052] S7. After drilling, use a vacuum cleaner or brush to clean the concrete debris, dust, and other impurities from the holes. Use a spirit level to measure the height difference between the surfaces of two adjacent floating slabs 7. If a height difference exists, locally grind the shear hinge installation area on the relatively higher side of the slab. When grinding, ensure that the thickness of the floating slab 7 after grinding meets the predetermined value of the minimum reinforcement protective layer to avoid affecting the reinforcement in the floating slab. Alternatively, add a shim to the installation area on the relatively lower side of the slab to ensure that the flatness error of the installation area is no more than 1mm, ensuring that the upper shear hinge 10 is evenly stressed after installation.

[0053] S8. Inject anchoring adhesive into the cleaned drill hole, then insert the sleeve or screw 12 into the hole, ensuring that the insertion depth and perpendicularity meet the requirements. Allow it to stand until the anchoring adhesive reaches the set strength. The standing time should be strictly controlled according to the substrate temperature. During the insertion process, the sleeve or screw 12 should not be pulled out and reinserted to avoid affecting the bonding strength.

[0054] S9. Before installing the top-mounted shear hinge 10, analyze the causes of damage or breakage of the built-in shear hinge 14. If the damage is caused by misalignment of adjacent floating slabs 7 due to tunnel settlement, foundation crushing, or spring breakage of the vibration isolator 9, the floating slabs 7 and track conditions should be adjusted first by adjusting the thickness of the shims in the vibration isolator 9 and lifting the floating slabs 7 to eliminate the misalignment before proceeding with subsequent operations. This will prevent the newly installed top-mounted shear hinge 10 from being damaged again due to misalignment. When installing the top-mounted shear hinge 10, place it on the installation area of ​​two adjacent floating slabs 7, aligning the fixing holes of the top-mounted shear hinge 10 with the implanted sleeves or screws 12. Replace the drilling bit of the drilling equipment 4 with a torque wrench, start the power equipment, and tighten the track spikes or threaded sleeves that cooperate with the sleeves or screws 12 diagonally and in stages according to the design torque value to firmly fix the top-mounted shear hinge 10 on the floating slabs 7.

[0055] S10. Using the lateral moving mechanism, slide the support base and the positioning platform 3, drilling equipment 4, inspection equipment 5, and rebar detection equipment 6 mounted on it to the installation position of the next set of upper shear hinges 10. Repeat steps S5 to S10 until all upper shear hinges 10 at the slab joint 11 are installed. After all upper shear hinges 10 are installed, check their stress state to ensure that the upper shear hinges 10 maintain a normal stress state and do not bear additional shear force due to uneven track or other reasons. If there is additional shear force, eliminate the error by adjusting the thickness of the shims in the vibration isolator 9, the shims or fastener shims under the upper shear hinges 10, etc. Finally, reinstall the sealing strip 13 above the slab joint 11 to complete the maintenance work.

[0056] When it is necessary to replace the embedded sleeve of the damaged upper shear hinge 10, the inspection of the built-in shear hinge 14 is not required, so step S2 is cancelled. In step S6, the operation of drilling a new installation hole is changed to drilling a hole to remove the failed embedded sleeve, then cleaning the hole, re-injecting the anchoring adhesive and inserting a new sleeve or screw 12, and the subsequent steps are the same as described above.
