[0048] Please refer to Figure 1-7 , the embodiment of the present application provides a support connection device for a suspended monorail track beam, including: a track beam 200 and a support column 100, and the track beam 200 is suspended and connected below the support portion 101 of the support column 100;

[0049] The support portion 101 and the track beam 200 are connected through a crossbeam structure 102, and the crossbeam structure 102 is arranged along the running direction.

[0050] The support connection device and the support connection method for the suspended monorail track beam of the present application use the crossbeam structure 102 arranged along the running direction to connect the support portion 101 of the track beam 200 and the support column 100. The crossbeam structure 102 arranged along the running direction can be adaptively adjusted according to specific parameters such as the length and stiffness of the track beam 200. For example, the number, length, stiffness, etc. of the crossbeam structure 102 can be adjusted to reduce the requirements for the track beam 200 and the support portion 101, so that a longer track beam size can be adopted under the same mass, or the weight of the track beam can be reduced under the same length, and the number of columns can be reduced, saving the land area; or the connection strength or their respective stiffnesses between the track beam 200 and the support portion 101 can be improved; or the stress concentration generated by the thermal expansion and contraction of the track beam 200 can be reduced.

[0051] As shown in the figure, the support portion 101 described in the present application can be arranged not only on the support column 100, but also on, for example, a rock wall or a building.

[0052] As shown in the figure, there can be various connection methods between the cross arm structure 102 described in the present application and the support part 101 of the support column 100. For example, it can be a fixed connection between the cross arm structure 102 and the support part 101, or an opening is made inside the support part 101, and the cross arm structure 102 passes through the support part 101, and adaptive adjustment can be made according to the parameters of the track beam 200 during connection and installation. Therefore, in the latter case, it is preferably set that the cross arm structure 102 passes through the support part 101 and its length is greater than the thickness of the support part 101. More preferably, the part of the cross arm structure 102 extending beyond the support part 101 is located inside the track beam 200.

[0053] In addition, the cross arm structure 102 described in the present application can be in various structural forms. For example, it can be a flat plate structure, or it can be composed of at least two strip-shaped elastic bodies arranged in the running direction and fixed at the support part 101. It is further preferably set that the strip-shaped elastic bodies are parallel to each other; by using multiple strip-shaped elastic bodies for the cross arm structure 102, while ensuring the stable installation of the track beam 200, the vibration generated when the train passes can be effectively transmitted and eliminated by utilizing the elastic deformation performance of the strip-shaped elastic bodies.

[0054] In addition, the cross arm structure 102 described in the present application can be located inside or above the track beam 200; in the foregoing description, the track beam 200 is suspended below the support part 101, the cross arm structure 102 is arranged along the running direction on the support part 101, and the arrangement direction of the cross arm structure 102 is the same as the running direction of the track beam 200. Under such an arrangement, an installation part 201 higher than the height of the track beam line passing structure can be provided at the connection part between the track beam 200 and the cross arm structure 102, so as to make the cross arm structure 102 located inside the track beam 200.

[0055] In addition, a clamping member 300 for vertically restricting is arranged between the cross arm structure 102 described in the present application and the track beam 200 along the running direction. The clamping member 300 can adopt an integral structure with an opening inside, or a combined component, that is, an upper clamping member 301 and a lower clamping member 302 are combined and arranged. As shown in the figure, the upper clamping member 301 and the installation part 201 can be connected by a connecting bolt 305, or the upper clamping member 301 and the lower clamping member 302 can be connected by a connecting bolt 305. Under a more preferable arrangement, upper clamping member sliding bushings 303 and lower clamping member sliding bushings 304 are respectively arranged at the connection parts between the upper clamping member 301, the lower clamping member 302 and the cross arm structure 102. In addition, it can also be set that the cross arm structure 102 is connected to the clamping member through a positioning hole 103 and a positioning pin 105. More preferably, a bushing 104 is arranged between the cross arm structure 102 and the support part 101.

[0056] In the case of adopting the combined setting of the upper clamping member 301 and the lower clamping member 302, the installation and connection of the support connection device are cheaper, and the manufacturing cost of the combined upper and lower clamping members is lower. In addition, when the upper clamping member 301 and the lower clamping member 302 are combined and set, appropriate adjustments can be made according to the installation situation during installation and connection. Furthermore, the track beam 200 can be fixedly connected integrally with the clamping member 300, or can be fixedly connected with the upper clamping member 301.

[0057] In addition, at least two-directional separate constraints are provided between the cross arm structure 102 and the clamping member 300. In the present application, the transverse direction is the running direction of the track beam 200, the longitudinal direction is the direction in which the plane is perpendicular to the running direction, and the vertical direction is the direction in which the vertical plane is perpendicular to the running direction. Optionally, the cross arm structure 102 and the clamping member 300 slide relative to each other longitudinally and are respectively constrained transversely and vertically; or the cross arm structure 102 and the clamping member 300 are respectively constrained longitudinally, transversely and vertically.

[0058] In addition, a damping member can be provided between the cross arm structure 102 and the clamping member 300 and / or the support portion 101 to reduce vibration noise; additionally, a shock-absorbing and wear-resistant material can also be provided between the cross arm structure 102 and the clamping member 300 and / or the support portion 101 to further eliminate noise.

[0059] In addition, for the convenience of installation and connection, when the track beam 200 in the present application is provided with an installation portion 201 corresponding to the clamping member 300, the cross arm structure 102 is located inside the track beam 200; along the longitudinal cross-section direction, the opening dimension L1 of the installation portion 201 is greater than the outer dimension L2 of the cross arm structure 102; under this setting, the direct hoisting and installation of the track beam 200 are convenient; it is also preferable that the installation portion 201 is correspondingly connected with the upper clamping member 301, and it is particularly preferable to connect by bolts or pins.

[0060] In addition, in the present application, it can also be preferably set that along the longitudinal cross-section direction, the opening dimension L1 of the installation portion 201 is smaller than the outer dimension L3 of the clamping member 300; under this preferred setting, the track beam 200, the cross arm structure 102 and the clamping member 300 can be more stable.

[0061] In addition, in the support connection device of the suspended monorail track beam in the embodiment of the present application, it can also be preferably set that the upper boundary line a1 of the support portion 101 is higher than the upper boundary line a2 of the track beam 200 or the installation portion 201 of the track beam 200, and the outer boundary line b1 of the support portion 101 along the running direction does not exceed the outer boundary line b2 of the track beam 200 along the running direction; under such a setting, the overall connection structure is compact, the external dimension is small, and the appearance is simple.

[0062] In addition, a cover plate can be provided above the track beam or the installation portion of the track beam in the present application to make its external structure simple.

[0063] The support connection method used in this application for the suspended monorail track beam can adopt the following method, especially with a clamping member 300 provided between the cross arm structure 102 and the track beam 200. The clamping member 300 is divided into an upper clamping member 301 and a lower clamping member 302. At the same time, the cross arm structure 102 is arranged inside the track beam 200, and the structure is set with an installation part 201 arranged on the upper part of the track beam 200; the support connection method includes the following steps:

[0064] 1) Place the lower clamping member 302 into the inside of the installation part 201 of the track beam 200, and hoist the track beam 200 below the support part 101, and place the cross arm structure 102 at the corresponding position of the lower clamping member 302;
