Description

TECHNICAL FIELD

[0001] The utility model relates to a car hook buffer device, especially a car hook buffer device for air track. BACKGROUND

[0002] The car hook buffer device is a vehicle component for connecting vehicles with each other, transmitting traction force, braking force and mitigating longitudinal impact force. The car hook is classified into screw car hook, tight type automatic car hook, automatic car hook and rotary car hook according to its structure type. The screw car hook is used earliest, but has been eliminated due to many defects. The tight type automatic car hook is mostly used for high-speed railway vehicles, and the current application range is narrow. The automatic car hook is commonly used at present.

[0003] The car hook buffer device is also used for connecting air track vehicles, but the length of the air track car hook buffer device is short due to the length and installation position of the vehicle, and the car hook buffer device still needs to have the functions of buffering energy absorption, automatic opening and locking. The existing car hook cannot meet the requirements. UTILITY MODEL CONTENT

The two ends of the buffer are connected to the car hook mounting seat and the hook head assembly through a pin shaft. A piston type hook tongue is mounted on the opposite side of the hook head assembly. A manual unhooking connecting rod is mounted on the hook head assembly. One end of the manual unhooking connecting rod is connected to the piston type hook tongue, and the other end of the manual unhooking connecting rod is provided with a handle.

[0006] Unlike the conventional car hook, the buffer is arranged on both sides of the whole device, and the space on both sides is fully utilized, so that the length of the car hook buffer device is reduced. The buffer can absorb the impact of compression and stretching, and can also provide a centering restoring force to realize automatic centering.

[0007] Further, a waist-shaped long hole is arranged on the car hook mounting seat, and the hook tail pin is arranged in the waist-shaped long hole.

[0008] The hook head assembly is mounted in a waist-shaped hole through the hook tail pin. When the car hook is stretched and compressed, the hook tail pin can move forward and backward in the waist-shaped hole.

[0009] Further, the device further comprises a proximity switch and an indicator. The proximity switch and the indicator are correspondingly matched and arranged. The proximity switch is mounted on the hook head assembly, and the indicator is mounted on the manual unhooking connecting rod.

[0010] Further, the manual uncoupling connecting rod is a group of connecting rod mechanisms composed of a plurality of rod members, which is arranged at the tail of the piston-type knuckle, wherein the rod member connected with the piston-type knuckle and the rod member provided with the handle are both arranged vertically relative to the piston of the piston-type knuckle.

[0011] The connecting rod mechanism is integrated at the tail of the piston-type knuckle, and manual uncoupling can be realized by manually pulling the connecting rod mechanism.

[0012] Further, two air holes are arranged on the piston cylinder of the piston-type knuckle in intervals, and a locking hook air path connector and an uncoupling air path connector are respectively arranged in the air holes, and the locking hook air path connector and the uncoupling air path connector are respectively connected with the air path of the vehicle body.

[0014] Further, the device further comprises an elastic supporting device, which is vertically arranged on the upper part of the coupler mounting seat and is parallel to the tail pin.

[0015] The elastic supporting device can provide a vertical restoring force, and when the coupler buffer device is drooping, the tail is pushed against by the lever principle, so that the coupler head is kept horizontal.

[0016] Further, four bolt holes with a rectangular distribution of connecting lines are arranged on the coupler mounting seat, and the four bolt holes are connected with the bogie frame by bolts.

[0017] Optimally, the tail pin and the pin shaft are round pins. The round pin connection has a large horizontal swing angle, and can meet the use condition of the minimum curve of 30 m.

[0018] Optimally, the buffer is a spring buffer.

[0019] Advantages: Compared with the prior art, the device has the following advantages:

[0032] The elastic supporting device 1 is vertically installed on the upper part of the vehicle knuckle mounting seat 2 and is parallel to the hook tail pin 3. When the hook head of the vehicle knuckle is lowered, the elastic supporting device 1 provides a restoring force to keep the hook head horizontal.

[0033] The device is different from the conventional vehicle knuckle, and the buffer is arranged on both sides of the vehicle knuckle, so that the space on both sides of the vehicle knuckle is fully utilized, and the length of the vehicle knuckle is reduced.
