Description

[0002] Track beams are a key component of suspended rail transit and provide load-bearing for suspended rail trains. Track beams are subject to a variety of complex forces, such as tensile force, compressive force, bending force, etc. Currently, many track beams generally adopt a bottom-opening box beam structure. The load borne by the side plates of the guide wheel driving path during driving is much smaller than the load borne by the bottom plate of the running wheel driving path. However, in order to ensure the overall structural strength of the track beam, the thickness of the top plate, side plate, and bottom plate are similar, resulting in a large weight of the track beam, low utilization of steel, and high cost. When the span of the track beam is large, the box beam structure does not meet the force requirements due to its excessive weight, and the track beams are mostly welded together. The force generated when the rail train passes by can easily damage the welded grooves due to force, resulting in unstable connections between the track beams. Utility Model Content

It should be understood that different dependent claims and features herein may be combined in a manner not described in the original claims. It may also be understood that the features described in conjunction with the individual embodiments may be used in other embodiments.

[0026] To solve the above problems, Figures 1 to 3As shown, the utility model provides a truss-type track beam, including a plurality of combined beam mechanisms 1 connected in sequence along the length direction, the combined beam mechanism 1 includes a main beam 11, a first running beam 12 and a first truss 13, the first running beam 12 is used for rolling connection with the running wheels of a train 4, two first running beams 12 are symmetrically arranged on both sides of the main beam 11 along the radial direction below the main beam 11, a plurality of first trusses 13 are respectively connected between the main beam 11 and the two first running beams 12, and the plurality of main beams 11 and the plurality of first running beams 12 arranged in sequence along the length direction are all hinged.

[0027] In this embodiment, a combined beam mechanism 1 is set as the main body of the track beam, and multiple combined beam mechanisms 1 are connected in sequence along the length direction, that is, the X-axis direction, to form a track beam. The combined beam mechanism 1 includes a main beam 11 and two first running beams 12. The two first running beams 12 are both located below the main beam 11, that is, in the negative direction of the Z axis, and are symmetrically located on both sides of the radial direction of the main beam 11, that is, on both sides of the Y axis in the plane where the Z axis and the Y axis are located. The two first running beams 12 and the main beam 11 are connected by multiple first trusses 13. The projections of the main beam 11 and the two first running beams 12 on the plane perpendicular to the length direction of the main beam 11, that is, on the plane where the Z axis and the Y axis are located, are isosceles triangles. The two running wheels of the track train 4 are respectively connected to the two first running beams 12 by rolling. The triangular structure is stable and can resist the deadweight of the track beam and The vertical deformation, lateral bending and twisting deformation caused by the load improve the structural strength of the track beam, and the isosceles triangle is more evenly subjected to the force of the track train 4, which prevents the combined beam mechanism 1 from being damaged by the force. The first truss 13 is used for connection instead of the steel plate of the box beam structure. While meeting the structural strength requirements, the overall weight of the track beam is reduced, which is convenient for assembling large-span track beams and saving costs. Along the length direction of the track beam, that is, the main beams 11 in the X-axis direction, and the adjacent first running beams 12 are all hinged. When the track train 4 passes through two adjacent combined beam mechanisms 1, the main beams 11 and the first running beams 12 can rotate slightly relative to each other under the action of external forces, dispersing the external forces in different directions, making it difficult for the connection between the combined beam mechanisms 1 to be damaged by external forces, thereby improving the stability of the track beam structure.

[0028] Specifically, using trusses instead of steel plates can also reduce the area where wind forces act and reduce the impact of wind forces on track beams.

The pier includes a vertical section 21 standing on the ground, and a horizontal section 22 vertically connected to the end of the vertical section 21 away from the ground. The extension direction of the horizontal section 22 is perpendicular to the length direction of the track beam, that is, the horizontal section 22 can extend along the Y-axis direction. The connecting beam mechanism 3 is connected below the horizontal section 22 and extends along the X-axis direction. The multiple combined beam mechanisms 1 and the multiple connecting beam mechanisms 3 are staggered and connected along the X-axis direction, and the two ends of the main beam 11 on the combined beam mechanism 1 and the first running beam 12 Both ends are hinged to the adjacent connecting beam mechanisms 3. The combined beam mechanism 1 is connected to the pier through the connecting beam mechanism 3. The force of the pier acts on the connecting beam mechanism 3, which reduces the force on the combined beam mechanism 1 and avoids damage to the combined beam mechanism 1 due to external force. The connecting beam mechanism 3 provides lateral support for the combined beam mechanism 1. Multiple combined beam mechanisms 1 are connected together to improve the structural stability of the track beam and increase the span of the track beam. The hinge between the combined beam mechanism 1 and the connecting beam mechanism 3 can disperse the external force on the connection and improve the overall structural stability.

[0031] Specifically, the track beam is formed by connecting a connecting beam mechanism 3 and a combined beam mechanism 1. The hinged structure is simple and easy to disassemble, which facilitates the inspection and replacement of the track beam. The length of the track beam can be adjusted by adjusting the number of connecting beam mechanisms 3 and combined beam mechanisms 1, which is suitable for different usage environments.

The second running beam 32 located in the negative direction of the Y-axis is arranged between the first running beams 12 located in the negative direction of the Y-axis in two adjacent combined beam mechanisms 1 and is connected by a hinge. The running wheels of the train 4 roll on the second running beams 32, and the connecting beam 31 provides lateral support for the combined beam mechanism 1, connects multiple combined beam mechanisms 1 together, improves the structural stability of the track beam, and can increase the span of the track beam. The hinged connection method can disperse the external force on the connection and improve the overall structural stability.

[0034] Specifically, the ends of the two connecting beams 31 connected together at an angle in the same direction can form a plug structure, and a connecting hole is opened on the plug structure along the Y-axis direction. A groove corresponding to the plug structure is opened at the end of the main beam 11, and the groove passes through in the Z-axis direction. The groove has connecting holes at both ends in the Y-axis direction. The plug structure is inserted into the groove, and bolts are set to pass through the multiple connecting holes to hinge the main beam 11 and the connecting beam 31. The main beam 11 can rotate around the Y-axis relative to the connecting beam 31; the main beam 11 can also rotate around the Z-axis relative to the connecting beam 31. In this way, the directions of the groove and the connecting hole change accordingly, which will not be repeated here; the connection method of the second running beam 32 and the first running beam 12 is the same as the connection method of the connecting beam 31 and the main beam 11, which will not be repeated here.
