Description

Technical Field

[0001] This utility model belongs to the technical field of track beam construction equipment, specifically relating to a three-dimensional positioning device and positioning system for a superconducting maglev track beam. Background Technology

[0002] With the continuous development of high-speed maglev transportation technology, the superconducting high-speed maglev test line, as a cutting-edge research project, has extremely high requirements for track construction precision. During track construction, the precise installation and positioning of the maglev track beam is one of the key aspects ensuring the stable operation of the maglev train. The applicant previously developed a scheme for erecting maglev track beams using a three-dimensional adjustable jack device. Specifically, existing Chinese patent CN104894977B discloses a method for erecting maglev track beams using a three-dimensional adjustable jack device. This device includes a base with a first groove on it. A second groove slides horizontally within the first groove, and a horizontally sliding vertical jack is located within the second groove. The sliding direction of the vertical jack within the second groove is perpendicular to the sliding direction of the second groove within the first groove. A piston on the vertical jack can extend and retract vertically. This three-dimensional adjustable jack device can adjust the track beam in the horizontal, vertical, and longitudinal directions with an adjustment accuracy of ±5mm in the horizontal and longitudinal directions, and ±2mm in the vertical direction. However, this solution achieves three-dimensional position adjustment by setting jacks in each of the three directions, requiring a large number of jacks for drive coordination, occupying a large space, making drive control difficult to coordinate, and resulting in high manufacturing costs.

[0003] Currently, since there is no similar superconducting maglev track structure in China, the operation is often carried out using methods analogous to the fine-tuning of high-speed rail track slabs. Specifically, the fine-tuning of high-speed rail track slabs uses four fine-tuning clamps. However, because these clamps are connected to pre-embedded sleeves on the side of the track slab via bolts, during the fine-tuning process, if the operators do not operate synchronously, the track slab will be subjected to torsional forces. This can cause cracks in the concrete around the pre-embedded sleeves on the side of the track slab due to stress, affecting the quality and durability of the track slab. For superconducting high-speed maglev tracks, which support maglev trains operating at speeds of 600 km / h and above, the durability of the maglev track beams plays a crucial role in the smooth operation of the maglev trains. Utility Model Content

[0004] The purpose of this invention is to provide a three-dimensional positioning device and positioning system for a superconducting maglev track beam, which aims to achieve automatic positioning of the superconducting maglev track beam.

[0005] This utility model is mainly achieved through the following technical solutions:

[0006] A three-dimensional positioning device for a superconducting magnetic levitation track beam includes a lifting jack, a movable base, and a fixed base arranged sequentially from top to bottom. A two-dimensional drive mechanism is provided between the movable base and the fixed base. A base groove is provided in the middle of the fixed base corresponding to the two-dimensional drive mechanism. The two-dimensional drive mechanism includes a longitudinal movement mechanism and a transverse movement mechanism. The longitudinal movement mechanism and the transverse movement mechanism each include a drive mechanism and a moving gear. The drive mechanism is used to drive the moving gear to rotate. The longitudinal movement mechanism and the transverse movement mechanism drive the movable base to move linearly along the Y and X directions, respectively, by driving the moving gear to rotate.

[0007] The movable base has longitudinal moving mechanisms on both sides of its bottom and a transverse moving mechanism in the middle; the groove of the base has a transverse spur gear meshing area in the middle corresponding to the moving gear of the transverse moving mechanism, and longitudinal spur gear meshing areas on both sides corresponding to the moving gear of the longitudinal moving mechanism; the surfaces of the transverse spur gear meshing area and the longitudinal spur gear meshing area are respectively provided with a lubricating layer.

[0008] To better realize this utility model, the top drive end of the lifting jack is further provided with a vertical lifting tray. The vertical lifting tray includes a tray body and an L-shaped support. The horizontal section of the L-shaped support is fixedly connected to the top drive end of the lifting jack, and the vertical section of the L-shaped support is connected to the tray body, so that the tray body is located at the lower part of the top drive end of the lifting jack.

[0009] To better realize this utility model, the longitudinal moving mechanism further includes a longitudinal moving gear and a longitudinal driving mechanism, and the lateral moving mechanism includes a lateral moving gear and a lateral driving mechanism. The longitudinal driving mechanism and the lateral driving mechanism are respectively mounted on the movable base, and the drive shafts of the longitudinal driving mechanism and the lateral driving mechanism are respectively connected to the longitudinal moving gear and the lateral moving gear.

[0010] This utility model is mainly achieved through the following technical solutions:

[0011] A three-dimensional positioning device for a superconducting magnetic levitation track beam includes a lifting jack, a movable base, and a fixed base arranged sequentially from top to bottom. A two-dimensional drive mechanism is provided between the movable base and the fixed base. A base groove is provided in the middle of the fixed base corresponding to the two-dimensional drive mechanism. The two-dimensional drive mechanism includes a longitudinal movement mechanism and a transverse movement mechanism. The longitudinal movement mechanism and the transverse movement mechanism each include a drive mechanism and a moving gear. The drive mechanism is used to drive the moving gear to rotate. The longitudinal movement mechanism and the transverse movement mechanism drive the movable base to move linearly along the Y and X directions, respectively, by driving the moving gear to rotate.

[0012] A longitudinal moving mechanism is provided on one side of the bottom of the movable base, and a longitudinal guide gear is provided on the other side; a transverse moving mechanism is provided in the middle of the bottom of the movable base; a transverse spur gear meshing area is provided in the middle of the groove of the base corresponding to the moving gear of the transverse moving mechanism, and longitudinal spur gear meshing areas are provided on both sides corresponding to the moving gear of the longitudinal moving mechanism and the longitudinal guide gear, respectively; a lubrication layer is provided on the surface of the transverse spur gear meshing area and the longitudinal spur gear meshing area.

[0013] To better realize this utility model, the top drive end of the lifting jack is further provided with a vertical lifting tray. The vertical lifting tray includes a tray body and an L-shaped support. The horizontal section of the L-shaped support is fixedly connected to the top drive end of the lifting jack, and the vertical section of the L-shaped support is connected to the tray body, so that the tray body is located at the lower part of the top drive end of the lifting jack.

[0014] To better realize this utility model, the hydraulic rod of the lifting jack and the drive mechanism of the longitudinal moving mechanism are respectively arranged on the left side of the movable base.

[0015] This utility model is mainly achieved through the following technical solutions:

[0016] A positioning system for a superconducting maglev track beam includes several of the aforementioned three-dimensional positioning devices, with two three-dimensional positioning devices respectively installed on both sides of the superconducting maglev track beam.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) This utility model, through the lubrication layers on the transverse and longitudinal spur gear meshing areas, enables the longitudinal and transverse moving gears to move axially or radially along the spur gear meshing area, achieving two-dimensional precise control of the lifting jack, reducing the space occupied by the drive, and making the drive more flexible. This utility model achieves the range limitation of two-dimensional control and eliminates the leakage of the lubrication layer through the base groove. This utility model uses gear movement to adjust the longitudinal and transverse displacement, which can prevent the accuracy deviation problem caused by the oil pressure drop of traditional hydraulic jacks. This utility model, by lifting the magnetic levitation track beam, can ensure that the magnetic levitation track beam is not damaged by external forces during the fine adjustment process.

[0019] (2) This utility model can achieve symmetrical dual-drive displacement control by installing longitudinal moving mechanisms on both sides. In order to adapt to narrow operating space, this utility model can also install a longitudinal moving mechanism on the outer end and a longitudinal guide gear on the inner end, so as to achieve symmetrical displacement control while saving operating space and having good practicality.

[0020] (3) This utility model establishes a positioning system based on several three-dimensional positioning devices. Through the flexible combination of these devices, stable and reliable installation of each superconducting maglev track beam can be achieved, demonstrating good practicality. Specifically, this utility model directly places the maglev track beam onto the three-dimensional positioning device. The use of a vertical lifting tray is applicable to different types of maglev track beams, and the maglev track beam does not form a mechanically fixed connection with the three-dimensional positioning device, thus solving the problem of damaging the maglev track beam in the prior art.

[0029] Example 1:

[0030] A three-dimensional positioning device for a superconducting magnetic levitation track beam, such as Figures 1-6As shown, the system includes: a lifting jack 1, a movable base 2, a fixed base 3, a transverse moving gear 5, a longitudinal moving gear 6, a vertical lifting tray 4, a longitudinal spur gear meshing area 7, a transverse spur gear meshing area 8, and a gear synchronous movement control system. The fixed base 3 has the movable base 2 on top, and the lifting jack 1 is mounted on top of the movable base 2. The base of the lifting jack 1 is fully welded to the movable base 2. The driving end of the lifting jack 1 has the vertical lifting tray 4, which is welded to the driving end of the lifting jack 1. The movable base 2 has longitudinal moving gears 6 rotatably mounted on both sides, and a transverse moving gear 5 rotatably mounted in the middle. The transverse moving gear 5 and the longitudinal moving gear 6 are perpendicular to each other. The top of the fixed base 3 is provided with a base groove 9, and a transverse spur gear meshing area 8 is provided in the middle of the base groove 9, and longitudinal spur gear meshing areas 7 are provided on both sides respectively; grease is added between the transverse moving gear 5, the longitudinal moving gear 6 and the spur gear meshing areas for lubrication. Specifically, a transverse spur rack and a longitudinal spur rack are respectively installed in the transverse spur gear meshing area 8 and the longitudinal spur gear meshing area 7.

[0031] Preferably, a vertical lifting tray 4 is fixedly provided at the top drive end of the lifting jack 1. The vertical lifting tray 4 includes a tray body and an L-shaped support. The horizontal section of the L-shaped support is fixedly connected to the top drive end of the lifting jack 1, and the vertical section of the L-shaped support is connected to the tray body, so that the tray body is located at the lower part of the top drive end of the lifting jack 1.

[0032] Preferably, the hydraulic rod of the lifting jack 1 is located on the left side of the movable base 2, and the longitudinal moving gear 6 and the transverse moving gear 5 located on the left side of the movable base 2 are respectively equipped with driving mechanisms. The drive shaft of the driving mechanism is connected to the corresponding moving gear to drive the moving gear to rotate.

[0033] Alternatively, the movable base 2 may be provided with a drive mechanism corresponding to the longitudinal moving gear 6 and the transverse moving gear 5, respectively.

[0034] In use, the movable base 2 is positioned within the base groove 9 of the fixed base 3 via a horizontal moving gear 5 or a vertical moving gear 6, allowing for two-dimensional position adjustment. The horizontal moving gear 5 adjusts the movable base 2's movement in the horizontal direction, while the vertical moving gear 6 adjusts its movement in the vertical direction. The base groove 9 prevents grease from overflowing and contaminating the device, and also limits the movable range of the movable base 2. The lifting jack 1 allows for precise vertical adjustment of the maglev track beam. The vertical lifting tray 4 supports the maglev track beam, creating localized surface contact.

[0035] Example 2:

[0036] A positioning system for a superconducting magnetic levitation track beam, such as Figure 7 As shown, the system includes several of the aforementioned three-dimensional positioning devices, with two three-dimensional positioning devices respectively installed on both sides of the superconducting maglev track beam. Simultaneously, four three-dimensional positioning devices are used for fine-tuning of a single superconducting maglev track beam. These four three-dimensional positioning devices are synchronously moved laterally or longitudinally by a gear synchronous movement control system via a lateral movement gear 5 or a longitudinal movement gear 6, thereby achieving fine-tuning of the track beam in both the lateral and longitudinal directions. The gear synchronous movement control system is existing technology and not an improvement of this invention; therefore, it will not be described further.

[0037] The specific operating method of this utility model during use is as follows:

[0038] Step 1: Determine the position of the three-dimensional positioning device by measuring and laying out the lines. Place four three-dimensional positioning devices on each superconducting maglev track beam and keep the upper surface of the vertical lifting tray 4 on a horizontal plane.

[0039] Step 2: Install the four three-dimensional positioning devices in their corresponding positions and connect them to the gear synchronous movement control system via wires.

[0040] Step 3: Use a gantry crane to lift the superconducting maglev track beam to the required installation position, and slowly lower the superconducting maglev track beam onto the vertical lifting tray 4 of the four three-dimensional positioning devices.

[0041] Step 4: Measure the required adjustment amount of the superconducting maglev track beam using measuring equipment such as a total station. Input the required lateral movement amount into the gear synchronous movement control system and simultaneously adjust the rotation of the four lateral movement gears 5 for lateral adjustment. Input the required longitudinal movement amount into the gear synchronous movement control system and simultaneously adjust the rotation of the four longitudinal movement gears 6 for longitudinal adjustment. Adjust the vertical elevation by adjusting the four lifting jacks 1.

[0042] Step 5: After adjustment, fix the superconducting maglev track beam, then lower the vertical lifting tray 4, remove the three-dimensional positioning device, and complete the fine adjustment of the superconducting maglev track beam.

[0043] Step 6: Repeat steps 1 to 5 to hoist, install, and fine-tune the next superconducting maglev track beam until all superconducting maglev track beams have been installed and fine-tuned.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
