[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.
[0026] A coupler buffer device for an empty rail, such as Figures 1 to 4 As shown, there are a hook tail vertical elastic support device 1, a coupler mounting seat 2, a hook tail pin 3, a buffer 4, a hook head component 5, a connecting pin shaft 6, a proximity switch 7, an indicator 8, a manual unhooking connecting rod 9, a hook locking air circuit connector 11, an unhooking air circuit connector 12, and a piston type hook tongue 13.
[0027] The coupler mounting seat 2 is provided with four bolt holes whose connecting lines are distributed in a rectangular shape, and is bolted to the bogie frame through the four bolt holes. One side of the hook head component 5 is connected to the coupler mounting seat 2 through the hook tail pin 3, and the hook head component 5 can rotate around the hook tail pin 3. The coupler mounting seat 2 is provided with a waist-shaped long hole, and the hook tail pin 3 is inserted into the waist-shaped long hole. The hook tail pin 3 can move forward and backward in the waist-shaped long hole, and synchronously drives the hook head component 5 to move forward and backward.
[0028] A buffer 4 is provided between the coupler mounting seat 2 and the hook head assembly 5 and on opposite sides of the coupler tail pin 3. The two ends of the buffer 4 are connected to the coupler mounting seat 2 and the hook head assembly 5 through a pin shaft 6. The buffer 4 can be a spring buffer. When the hook head assembly 5 moves forward and backward, the buffer 4 is compressed or stretched, so that the buffer 4 starts to work and reduces the longitudinal impact. The coupler tail pin 3 and the pin shaft 6 are both round pins.
[0029] The piston-type hook tongue 13 is installed on the other side of the hook head component 5, and the manual unhooking connecting rod 9 is installed on the hook head component 5, one end of which is connected to the piston-type hook tongue 13, and the other end is provided with a handle. The manual unhooking connecting rod 9 is a group of connecting rod mechanisms composed of a plurality of rods hinged together, which is approximately φ-shaped and is arranged at the tail of the piston-type hook tongue 13, wherein the rod connected to the piston-type hook tongue 13 and the rod provided with the handle are both arranged vertically relative to the piston of the piston-type hook tongue 13. When manual unhooking is required, the manual unhooking connecting rod 9 can be pulled to achieve manual unhooking. In the initial state, the manual unhooking connecting rod 9 has no effect on the extension and contraction of the piston-type hook tongue 13, and moves with its piston.
[0030] Two air holes are arranged on the piston cylinder of the piston-type hook tongue 13, which lead to two air chambers in the cylinder body respectively. The two air holes are respectively installed with the hook locking air circuit joint 11 and the hook unhooking air circuit joint 12, which are respectively connected to the air circuit of the vehicle body. Solenoid valves are respectively arranged on the air circuits connected to the hook locking air circuit joint 11 and the hook unhooking air circuit joint 12, and the hook locking air circuit joint 11 and the hook unhooking air circuit joint 12 can both inlet and outlet air, thereby driving the piston of the piston-type hook tongue 13 to reciprocate, and realize the automatic unhooking and automatic hook locking functions.
[0031] The proximity switch 7 and the indicator 8 are matched and arranged correspondingly, the proximity switch 7 is installed on the hook head component 5, and the indicator 8 is installed on the manual unhooking link 9. When the hook is unhooked and locked, the indicator 8 is displaced, thereby giving a signal to the proximity switch 7, realizing the function of real-time monitoring of the coupling state of the vehicle coupler.
[0032] The elastic support device 1 is vertically mounted on the upper part of the coupler mounting seat 2 and is parallel to the coupler tail pin 3. When the coupler hook head is lowered, the elastic support device 1 provides a restoring force to keep the hook head horizontal.
[0033] This device is different from conventional couplers in that the buffers are arranged on both sides of the coupler, making full use of the space on both sides of the coupler and reducing the length of the coupler.
[0034] The piston-type hook tongue and other components are integrated into a cylinder mechanism, which is used as a driving unit to control the movement of the cylinder to achieve the functions of automatic unlocking and automatic hook locking.
[0035] A connecting rod mechanism is integrated at the tail of the cylinder mechanism, and manual unhooking can be achieved by manually pulling the connecting rod mechanism.
[0036] Spring buffers are installed on both sides of the entire device, which can absorb the impact of compression and stretching, and provide centering restoring force to achieve automatic centering; the coupler head is installed in a waist-shaped hole through the coupler tail pin, and when the coupler is stretched and compressed, the coupler tail pin can move back and forth in the waist-shaped hole.
[0037] Round pins are used at all locations on the coupler for connection, and the horizontal swing angle is large, which can meet the operating conditions of a minimum curve of 30m.
[0038] There is an elastic support device at the tail of the coupler, which can provide vertical restoring force. When the coupler head droops, the lever principle is used to support the hook tail to keep the coupler head horizontal.
[0039] A proximity switch is set under the coupler head. When the coupler is unhooked and locked, the position of the manual unhooking linkage mechanism from the proximity switch is different, thereby giving different output signals, which can monitor the coupling status of the coupler in real time.
[0040] The present invention controls the total length of the coupler very compactly through ingenious structural design to meet the requirements of vehicle body size. The coupler also has the functions of automatic unhooking, automatic hook locking, manual unhooking, automatic centering, buffer energy absorption device, anti-lowering, real-time monitoring of coupling status, etc., which can meet the use scenario requirements of aerial rail vehicles.
