Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of maglev monorail transportation, in particular to a joint type maglev turnout structure and turnout line shape. BACKGROUND

[0002] The medium-low speed maglev rail transit has the advantages of low noise, low vibration, low radiation, low cost and strong climbing ability, and is a new direction of urban rail transit development. The medium-low speed maglev turnout is an important structure for realizing the reversing of the maglev line.

[0003] At present, the maglev turnout structure in operation is mostly composed of multiple joint beams, for example, the utility model patent with publication number CN108589438A, the turnout beam body is mainly composed of a fixed stack beam, a second driven beam, a first driven beam, a driving beam and a movable stack beam (109). A hinge shaft connecting rod I and a hinge shaft connecting rod II are arranged below the turnout beam body, which are used to determine the turnout rotation center position. However, the structure has the following defects:

[0004] Firstly, the hinge shaft connecting rod is internally provided with a joint bearing structure, which will be worn out after a long time of switching, causing the turnout failure. The space below the beam body of the existing maglev turnout structure is small, and the replacement of the hinge shaft connecting rod components requires the beam body above to be disassembled in advance, and the disassembly of the beam body above can only be realized by hoisting to replace the components. Therefore, the replacement operation is not convenient, and it is difficult to replace the components below the beam body in a short time after the components fail. At the same time, the operation unit of the maglev line needs to regularly maintain these components, which is difficult to replace, resulting in high difficulty in maintaining the turnout structure; the overall turnout manufacturing cost and operation cost are high.

[0005] Secondly, due to the working principle of the turnout, the hinge shaft connecting rod structure is very large, at least longer than the length of the first driven beam structure, increasing the complexity of the turnout installation, and when the turnout side line is switched, the fitting radius is poor.

[0006] Thirdly, the existing joint type turnout line shape has an angle between the broken lines that is not smooth enough, and for the maglev transportation with higher requirements for the line, the line shape cannot meet the requirements of the maglev turnout, and the application has certain limitations.

[0007] In addition, the existing medium-low speed maglev turnout driving beam has the disadvantages of being long and heavy, which brings great inconvenience to the installation of the turnout on site, especially for the installation of the turnout in the tunnel, the long and heavy driving beam greatly increases the hoisting cost of the turnout.

The joint beam connected with the movable stack beam 109 is driven by the driving device 5 to slide on the turnout foundation 3 to switch, and is respectively connected with the corresponding movable stack beam 109 before and after the switching. The joint beam is driven to move by the driving device 5, and the passive beam 106 is indirectly driven to move, so that the passive beam 106 does not need to be provided with the driving device 5 to realize the movement.

During switching, under the driving of the same reduction motor 501, the movement distance of the joint beam at the long swing arm 502 end is greater than that of the joint beam at the short swing arm 503, so as to cooperate with the obtuse angle required for the joint beam to form a fitting curve with the joint beam.

[0063] In implementation, referring to Figure 7 , the trolley 2 is further provided with a locking device 4, which includes a power device and a locking pin 401. The turnout foundation 3 is provided with a straight position slot 3001 and a side limiting position slot 3002 for the locking pin 401 to cooperate with the insertion. So that: when the locking pin 401 is inserted into the straight position slot 3001, the trolley 2 is locked in the position before switching; when the locking pin 401 is inserted into the straight position slot 3001, the trolley 2 is locked in the position after switching.

When not in use, the locking device 4 is covered with a stainless steel cover to prevent damage from external bumps.

[0064] Correspondingly, referring to Figure 1 and Figure 2The application also provides a joint type turnout line shape, which is composed of a turnout, and the turnout comprises a plurality of joint beams which are sequentially and movably connected in a head-to-tail manner, when the turnout is switched, the joint beams rotate towards the side line position, so that the connection between adjacent joint beams is rotated to form an angle to make the plurality of joint beams fit the side line curve after the turnout is switched, a passive beam 106 is arranged between adjacent joint beams for transition, the included angle between every two adjacent joint beams after switching is alpha, and the included angle between the passive beam 106 and adjacent joint beams after switching is alpha / 2. The passive beam 106 is arranged between adjacent joint beams for transition, the passive beam 106 divides the included angle of the joint beam by half, and the transition angle of the broken line is again divided, so that the curve line shape can be better fitted, and the smoothness of the vehicle passing through the turnout can be improved.

[0066] In summary, the joint type magnetic levitation turnout structure and the turnout line shape can again divide the switching angle of the switching broken line formed by the joint beam, better fit the curve line shape, and improve the smoothness of the vehicle passing through the turnout.

[0067] In the preferred scheme, the turnout beam bodies are connected through joint hinge shafts 107, the turnout system no longer adopts the hinge shaft connecting rod structure, and the weak point of the turnout can be reduced.
