Description

Technical Field

[0001] This invention relates to the technical field of transportation tracks, and in particular to a settlement control device utilizing a track-mounted mobile bolt tightening and loosening robot. Background Technology

[0002] High-speed maglev vehicles using conventional electromagnetic systems levitate on tracks by hugging the rails. Compared to wheel-rail transportation, maglev transportation completely breaks free from the constraints of the wheel-rail relationship and reduces friction with the track. Maglev transportation performs better in terms of speed, climbing ability, capacity, power, load, comfort, safety, energy saving and environmental protection, and is expected to achieve speeds of 600 kilometers per hour or even higher.

[0003] In response to the unique operating mode and the relationship between the vehicle and track system of conventional electromagnetic high-speed maglev trains, the Shanghai Maglev Demonstration Line, built in 2002, adopted an integrated beam-track design. Functional components are installed at the cantilever ends of the top plate of the beam structure. The high-precision track beam structure is combined with the bridge via supports to form an integral track beam structure. This integral track beam structure places extremely high demands on the manufacturing and processing of the track beam. Furthermore, during line operation, changes in the track surface alignment due to settlement, concrete shrinkage, and creep necessitate manual adjustment of the beam structure supports to correct the track surface elevation. Manual maintenance involves a series of tasks, including operating jacks and tightening support bolts. Due to its high labor intensity, slow speed, and low adjustment efficiency, track alignment maintenance is inconvenient. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a settlement control device utilizing a track-side mobile bolt tightening and loosening robot, enabling high-precision control of high-speed maglev tracks and providing fully automated, fine-tuning adjustment of the supports between the track beam and the piers. To achieve the above-mentioned objectives and other advantages of the present invention, a settlement control device utilizing a track-side mobile bolt tightening and loosening robot is provided, comprising:

[0005] The main girder of the bridge has two track beams, each with parallel side-mounted tracks, and the side-mounted tracks of each track beam are connected to each other.

[0006] The bridge pier body is equipped with multiple adjustable nut supports. Each adjustable nut support is equipped with a side rail, and each side rail near the adjustable nut support is equipped with a hydraulic lifting position at one end.

[0007] The side-mounted track is equipped with a movable, fully automatic hydraulic lift, which is equipped with an automatic bolt tightening / loosening robot.

[0008] Preferably, the bottom of the fully automatic hydraulic lift is fixed with multiple free-swerving guide wheels, which are matched with the side-mounted rails.

[0009] Preferably, the automatic bolt tightening / loosening robot is equipped with a freely flexible and rotating robotic arm, the top of which is fitted with a nut tightening head.

[0010] Preferably, one of the main bridge beams is equipped with a side-mounted track along the maglev line, and the width of the edge stone opening of one of the main bridge beams is just wide enough to allow the fully automatic hydraulic lift and the bolt automatic tightening / loosening robot to enter and exit freely.

[0011] Preferably, the side-mounted track is placed at the same level as the top surface of the main bridge beam.

[0012] Preferably, a group of four mobile, fully automatic hydraulic lifts and automatic bolt tightening / loosening robots are distributed every 500 meters along the maglev track.

[0013] Preferably, a rest station is distributed every 500 meters along the maglev track, and the rest station includes a rest station shield, a charging compartment and an openable and closable curtain.

[0014] Preferably, after the adjustable nut support is repaired, the four sets of mobile fully automatic hydraulic lifts and bolt automatic tightening / loosening robots in every 500-meter section, driven by motors, return to the nearest rest station for rest and charging via free-steering guide wheels along the side-mounted track, in preparation for the next maintenance work.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: The settlement control system described in this invention can improve the maintenance quality and precision of the track structure. Under the premise that settlement is unavoidable, it can promptly and autonomously adjust the supports, effectively meeting the adjustment needs of track beam supports in various application scenarios, preventing excessive waste in civil engineering design, and reducing initial construction costs. Fundamentally, it avoids attributing settlement problems to the track, mechanical, electronic, and control fields, achieving true high-precision settlement control. This is beneficial for ensuring the smooth operation, speed increase, and passenger comfort of maglev lines during operation, improving the reliability of maglev tracks, and ensuring the possibility of long-term maintenance across the entire line. It has excellent application prospects and is of great significance to the operation and maintenance of high-speed maglev in my country. Attached Figure Description

[0024] 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.

[0025] Reference Figure 1-8 A settlement control device using a track-mounted movable bolt tightening robot includes: a bridge main beam 3, on which two track beams 1 are provided, each track beam 1 is provided with parallel side-mounted tracks 6, and the side-mounted tracks 6 of each track beam 1 are connected to each other.

[0026] The pier body 5 is provided with multiple adjustable nut supports 2. Each adjustable nut support 2 is provided with a side rail 6. Each side rail 6 near the adjustable nut support 2 is provided with a hydraulic lifting position 10 at one end.

[0027] A movable, fully automatic hydraulic lift 7 is mounted on the side-mounted track 6, and an automatic bolt tightening / loosening robot 8 is mounted on the lift 7. Multiple free-swerving guide wheels 9 are fixed to the bottom of the lift 7, and these guide wheels 9 are matched with the side-mounted track 6. The automatic bolt tightening / loosening robot 8 is equipped with a freely flexing and rotating robotic arm 14, and a nut tightening / loosening head 15 is installed at the top of the robotic arm 14. The track beam 1 is mounted on the main bridge beam 3 via adjustable nut supports 2. The side-mounted track 6 is installed on the side of the main bridge beam 3 and laid along the maglev line. The automatic hydraulic lift 7, equipped with the automatic bolt tightening / loosening robot 8, is connected to the side-mounted track 6 via the free-swerving guide wheels 9 and moves on the side-mounted track 6. The automatic bolt tightening / loosening robot 8 performs fine adjustments by tightening the adjustable nut supports 2, raising or lowering the two sides of the track width according to the monitoring and calculation results.

[0028] like Figure 1-2 As shown, one of the main bridge beams 3 has a side-mounted track 6 laid along the maglev line, and the opening width of the edge stone 4 of one main bridge beam 3 is just wide enough for the fully automatic hydraulic lift 7 and the automatic bolt tightening / loosening robot 8 to freely enter and exit. Traveling mechanisms operate simultaneously on the side-mounted tracks 6 on both sides of the bridge. Two sets of traveling mechanisms move simultaneously on each side track. Each set of traveling mechanisms includes four freely steerable guide wheels 9, on which one of the wheels carries the fully automatic hydraulic lift 7 and the automatic bolt tightening / loosening robot 8, moving longitudinally along the side-mounted track 6 to the T-shaped track near the target pier. Figure 3 As shown, the free-steering guide wheel 9 rotates 90° to steer.

[0029] like Figure 1-2 As shown, after turning, the free-steering guide wheel 9 moves horizontally along the maglev line, delivering the fully automatic hydraulic lift 7 and the automatic bolt tightening / loosening robot 8 mounted on it to the T-shaped track in front of the hydraulic jacking position 11. The free-steering guide wheel 9 rotates 90 degrees and turns again. After turning, the free-steering guide wheel 9 moves horizontally along the maglev line, delivering the fully automatic hydraulic lift 7 and the automatic bolt tightening / loosening robot 8 to the hydraulic jacking position 10.

[0030] When adjustments are required, the automatic bolt tightening / loosening robot 8 uses the extension and rotation of the robotic arm 14 to accurately position the nut tightening head 15 on the nut of the adjustable nut support 2, loosens the nut of the adjustable nut support 2, and rotates it to realize the raising and lowering of the adjustable nut support 2, thus completing the height adjustment of the corresponding side of the track beam; after the adjustment is completed, the nut tightening head 15 tightens the nut, completing the adjustment of the adjustable nut support 2.

[0031] The free-steering guide wheel 9 continues to send the fully automatic hydraulic lift 7 and the bolt automatic tightening / loosening robot 8 to the next hydraulic lifting position, repeating the above operation to complete the adjustment of the adjustable nut support 2.

[0032] After all the adjustable nut supports 2 on the main beam 3 of the bridge have been adjusted, the free-steering guide wheel 9 will retract the fully automatic hydraulic lift 7 and the bolt automatic tightening / loosening robot 8 to the side rail 6.

[0033] Repeat the above operation, and the free-steering guide wheel 9 moves longitudinally along the side-mounted track 6 to the vicinity of the next target pier body 5, completing the adjustment of the adjustable nut support 2.

[0034] like Figure 4 As shown, based on the preliminary monitoring and calculation results, the fully automatic hydraulic lift 7 lowers the track beam from the bottom to the required height. However, it should be noted that the precise data for adjusting the height of the nut support is provided by the automatic track unevenness measurement system, which is not within the scope of this invention patent.

[0035] Furthermore, the side-mounted track 6 is placed at the same level as the top surface of the main bridge beam 3.

[0036] Furthermore, a group of four mobile, fully automatic hydraulic lifts 7 and automatic bolt tightening / loosening robots 8 are distributed every 500 meters along the maglev track. A rest station is located every 500 meters along the maglev track, comprising a rest station shield 11, a charging compartment 12, and an openable / closable curtain 13. The simultaneous operation of multiple groups allows for efficient routine maintenance of the adjustable nut supports 2 during non-operational nighttime hours. After adjusting all adjustable nut supports 2 within the specified 500-meter range, the free-steering guide wheel 9 transports the fully automatic hydraulic lifts 7 and automatic bolt tightening / loosening robots 8 along the maglev line direction to the nearest rest station for periodic maintenance and charging of the system.

[0037] Furthermore, after the adjustable nut support 2 is fully installed, the four sets of movable fully automatic hydraulic lifts 7 and bolt automatic tightening / loosening robots 8, which are installed every 500 meters, return to the nearest rest station for rest and charging via the free-turning guide wheels 9 and the side-mounted track 6, driven by motors, in preparation for the next maintenance work.

[0038] Therefore, this invention provides a settlement control device utilizing a track-mounted mobile bolt tightening and loosening robot, which can automatically and precisely adjust the supports, easily and instantly adjusting the track flatness as needed under various complex natural and geological environments. This solves the problems of high labor intensity and low efficiency in the manual maintenance of existing maglev track supports, reduces the human error rate, and improves the reliability of maglev tracks. It has promising application prospects and is of great significance to the operation of high-speed maglev in my country.

[0039] The number of devices and processing scale described herein are for the purpose of simplifying the description of the invention, and applications, modifications and variations thereof will be apparent to those skilled in the art.

[0040] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
