However, these structures typically employ embedded joint structures with appropriate shapes and specifications for the specific gaps encountered in single-turnout operation. However, these structures are unable to meet the diverse gap shapes and specifications required in multi-turnout operation, resulting in unreliable joints.

[0025] The present application is described below with reference to specific embodiments in conjunction with the accompanying drawings.

[0026] The present disclosure solves the technical problem of unreliable joint effect between the turnout beam and the track beam of the pivot-type suspended monorail multi-turnout system in the prior art by providing a pivot-type suspended monorail multi-turnout beam and a running rail joint device thereof.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0028] Referring to Figure 1, the present disclosure provides a running rail joint device for a pivot-type suspended monorail multi-turnout beam, which can cope with the diverse gap shapes and specifications, meet the working conditions of the multi-turnout beam, and improve the reliability, adaptability and stability of the joint.

[0029] In some embodiments, the running rail joint device of the pivot-type suspended monorail multi-opening turnout beam forms a deflected joint structure of the joint plate 10 by setting a joint plate 10, a rotating support 20, a shift rod 30 and a push-pull assembly 40, and realizes the joint by covering the gap, thereby having a wide adaptability to gaps of different shapes and sizes, and completing a reliable and stable joint.

[0030] The joint plate 10 is provided with a rotation shaft 12 along the plate surface direction. The rotation shaft 12 is rotatably embedded in the rotation support 20 ; thus, the joint plate 10 can rotate relative to the rotation support 20 .

[0031] The first end of the lever 30 is fixed to the joint plate 10, and the second end of the lever 30 is connected to the push-pull assembly 40. The push-pull assembly 40 allows the joint plate 10 to be pushed and deflected to cover the gap or stand upright. Therefore, simply rotating the joint plate 10 can achieve reliable and efficient jointing of various gaps. Furthermore, the structure is relatively simple, making it easy to install on-site.

[0032] The push-pull assembly 40 is used to provide a driving torque to drive the deflection of the deflector rod 30. During assembly, the rotating support 20 is fixed to the turnout beam. Accordingly, the push-pull assembly 40 can also be fixed to the turnout beam, thereby applying force to the deflector rod 30. To meet the rotation requirements of the deflector rod 30, the specific implementation scheme of the push-pull assembly 40 is relatively diverse.

[0033] In some embodiments, the push-pull assembly 40 includes an axial push-pull member 41 , a push rod head 42 , and a pin 43 ; a waist-shaped hole 31 is defined on the main body of the shifting rod 30 .

[0034] The push rod head 42 is connected to the axial moving end of the axial push-pull member 41, and can move axially back and forth under the drive of the axial push-pull member 41 to perform push-pull operations; the pin shaft 43 is arranged on the push rod head 42, and the pin shaft is embedded in the waist-shaped hole 31, and the pushing and pulling direction of the axial push-pull member 41 intersects with the long axis direction of the waist-shaped hole 31, so that while ensuring that the push rod head 42 moves back and forth in a straight line, it can move along the waist-shaped hole 31 through the pin shaft 43 and push the dial rod 30 to deflect; the driving operation is simple and efficient.

[0035] In order to ensure that the process of the joint plate 30 being flattened and covering the gap is stable and reliable, the position of the push rod head 42 relatively away from the joint plate 10 is the initial position, corresponding to the flattened joint state of the joint plate 10, and the position of the push rod head 42 relatively close to the joint plate 10 is the action limit position of the axial push-pull member 41, corresponding to the upright and disconnected joint state of the joint plate 10; therefore, by coordinating the waist-shaped hole 31 with the driving structure of the axial push-pull member 41, the deflection speed of the lever 30 can be gradually reduced when the joint operation is implemented, that is, fast at first and then slow, with efficient action, and it can be placed on the switch beam and the connected track beam at a low speed and steadily to ensure the quality of the joint; or, when the switch beam is switched and the joint plate 10 is retracted, the deflection speed of the lever 30 can be gradually increased, that is, slow at first and then fast, slowly starting to disengage from the track beam surface, accelerating to disengage, and quickly reaching its position, adapting to the switching operation of the switch beam, and improving operating efficiency.

[0036] Since the pin 43 transmits the axial push-pull torque, to ensure the stability and reliability of the torque, the push rod head 42 is configured as a U-shaped bracket 42a. The pin 43 is rotatably embedded in the two arms of the U-shaped bracket 42a, thereby ensuring the stable force on the pin 43. The bottom of the U-shaped bracket 42a is fixed to the axial push-pull member 41, ensuring a stable connection.

[0037] In some embodiments, the axial push-pull member 41 adopts an electric push rod 41 a , the end of the electric push rod 41 a is connected to the push rod head 42 , and the rod body of the electric push rod 41 a is electromagnetically driven to move axially to achieve axial push-pull force.

[0038] In some embodiments, the electric push rod 41a is a specific push-pull member, and an action element such as an electric hydraulic cylinder or a pneumatic cylinder may also be used; this is not limited here.

[0039] In some embodiments, the deflection drive of the lever 30 is realized by the axial push-pull member 41, the lever 30, and the waist-shaped hole 31. In addition, a motor drive structure, a reduction structure, and a connecting rod can be used to directly connect to the lever 30 to drive the deflection.

[0040] 2 and 3 , in other embodiments, a pivot-type suspended monorail multi-opening turnout beam based on the above-mentioned joint device is also provided; it includes: a turnout beam body 50 and the running rail joint device of the above-mentioned pivot-type suspended monorail multi-opening turnout beam.

[0041] The running rail joint device is arranged at the end of the turnout beam body 50 , and cooperates with the switching process of the turnout beam body 50 to realize the joint operation of the gap between it and the branch track beam 60 .

[0042] In order to reduce the influence of the joint device on the flatness of the track surface on the turnout beam main body 50, a sunken platform 51 can be opened on the track surface of the turnout beam main body 50, and the rotating support 20 is arranged in the sunken platform 51. A joint plate accommodating area 51a is opened in the sunken platform 51, and the joint plate 10 is placed in the joint plate accommodating area 51a; thereby avoiding the installed rotating support 20 and the joint plate 10 protruding from the track surface of the turnout beam main body 50, ensuring its flatness and reducing the influence on driving.

[0043] A lever-receiving hole 52 is defined within the sinking platform 51 and extends through the turnout beam body 50. The lever 30 is pivotably positioned within the lever-receiving hole 52, thereby securing the axial push-pull member 41 within the turnout beam body 50, below the running rail surface. The joint plate 10 rests on the running rail surface. Overall, the small, simple joint device is well suited to the interior space of the turnout beam body 50. The simple deflection within a range of slightly greater than 90 degrees allows for efficient and stable jointing of gaps of various sizes and shapes, fully adapting to the jointing conditions of pivotally suspended monorail multi-opening turnout beams.

[0044] In order to ensure smooth undulations of the track surface after the joint, the depth of the joint plate accommodating area 51a relative to the track surface is equal to the thickness of the joint plate 10, thereby ensuring that the running track surface of the switch beam is flat in the joint state.

[0045] 1 , the push-pull assembly 41 may be provided with fasteners 44 so as to be detachably fixed below the turnout beam body 50 .

[0046] The edge of the joint plate 10 is provided with an arc-shaped connecting section 11, so that it can be connected with the track surface sunken platform 61 of the branch track beam 60 through a smooth transition connection; the arc-shaped structural form can meet the joint postures of various angles and shapes, and the side walls of the track surface sunken platform 61 of the branch track beam 60 are also set to be arc-shaped.

[0047] In order to meet the reliability requirement of the stress state, the first end 32 of the shifting rod 30 is welded to the bottom surface 14 and the side surface 13 of the joint plate 10 respectively, so as to achieve stable fixation.

[0048] The present disclosure relates to some embodiments of a pivot-type suspended monorail multi-opening switch beam and its running rail joint device, which provide a rotating support to rotatably support the joint plate, and provide a shift rod and a push-pull assembly to provide deflection power to push the joint plate to deflect, so that it can stand up and flatten on the track surface of the switch beam running rail, respectively meeting the functional requirements of the joints during the switching process and after the switching, and can cover the joints in a flattened state, thereby meeting the joint requirements of gaps of various shapes and specifications, with high reliability and strong adaptability; and the joints are implemented by deflection, with simple structure and operation, and high efficiency and reliability.
