Referring to Fig. 1, the present disclosure provides a running rail joint device for a pivot-type suspended monorail multi-opening turnout beam, which can meet the requirements of working conditions of multi-opening turnout beams and improve the reliability, adaptability and stability of the joint.

In some embodiments, the jointing device of the running rail of the pivotal suspended monorail multi-opening turnout beam forms the deflected joint structure of the joint plate 10 by setting the joint plate 10, the rotating support 20, the driving lever 30 and the push-pull assembly 40, and realizes the joint by covering the gap, so that it has a wide adaptability to gaps of different shapes and specifications, and completes reliable and stable joints.

Wherein, the joint plate 10 is provided with a rotating shaft 12 along the direction of the plate surface, and the rotating shaft 12 is rotatably embedded in the rotating support 20 ; thus, the jointing plate 10 can rotate relative to the rotating support 20 .

The first end of the driving rod 30 is fixed on the seam plate 10, and the second end of the driving rod 30 is connected with the push-pull assembly 40, so that the push-pull assembly 40 can push the seam plate 10 to deflect, cover the gap or stand up. Therefore, a wide range of reliable and efficient seaming operations for various gaps can be realized through a simple deflection operation of the seaming plate 10; moreover, its structure is relatively simple, and it has good adaptability for on-site installation.

The push-pull assembly 40 is used to provide driving torque to drive the shift lever 30 to deflect. During assembly, the rotating support 20 is fixed to the turnout beam. Correspondingly, the push-pull assembly 40 can also be fixed to the turnout beam to apply force to the shift lever 30 based on it. In order to meet the rotation requirement of the lever 30, the specific implementations of the push-pull assembly 40 are various.

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

In order to ensure that the seam plate 30 falls flat and covers the gap, the process is stable and reliable. The position of the push rod head 42 relatively away from the seam plate 10 is the initial position, which corresponds to the flattened seam state of the seam plate 10. The position of the push rod head 42 relatively close to the seam plate 10 is the action limit position of the axial push-pull member 41, corresponding to the state of the joint plate 10 standing up and breaking the seam; The deflection speed of 30 decreases gradually, that is, the first Fast and then slow, high-efficiency action, and low-speed and stable shelving on the turnout beam and the connected track beam to ensure the quality of the joint; or, when the switch beam switch is implemented to retract the joint plate 10, the deflection speed of the lever 30 is gradually increased, that is, slow first and then fast, slowly start off the track beam surface, accelerate to break away, and quickly arrive in place, adapt to the switch operation of the turnout beam, and improve operating efficiency.

In some embodiments, the electric push rod 41a is a specific push-pull member, and action elements such as electric hydraulic cylinders and air cylinders can also be used; there is no limitation here.

In some embodiments, the deflection driving of the driving rod 30 is realized by axially pushing and pulling the member 41 , the driving rod 30 and the waist hole 31 .
