[0024] The embodiments of the utility model will be described in detail below with reference to the drawings.
[0025] Reference Figure 1A traction device, comprising an electric push rod 2, a hook body 3, a car hook pin 5 and a traction assembly; the first end of the hook body 3 is provided with a bending part capable of hooking the car hook pin 5, the middle part of the hook body 3 is hinged to the first carriage for the hook body 3 to be rotatable away from or hook the car hook pin 5; one end of the electric push rod 2 is hinged to the first carriage and the other end is hinged to the second end of the hook body 3 for pushing the hook body 3 to rotate; the car hook pin 5 is connected with the second carriage through the traction assembly.
[0026] The electric push rod pushes the hook body to rotate, so that the hook body automatically hooks and separates from the car hook pin, realizing the quick and convenient connection and separation of the carriages; and the structure is simple, the reliability is good, and the application range is wide.
[0027] The traction assembly is also provided with metal sensing sheets 10 corresponding to the positions of the proximity switches 4. Through the design of the proximity switches and the metal sensing sheets, it can be conveniently and quickly judged whether the hook body is completely separated from the car hook pin at a long distance. After uncoupling, the rear vehicle can be braked according to the state information of the traction device, so as to prevent the rear vehicle from rushing out of the track.
[0028] The proximity switches 4 are each provided with a group on the two side surfaces of the hook body 3, and the metal sensing sheets are also provided with two groups corresponding to the proximity switches. Through the design of the two groups of proximity switches and the metal sensing sheets with springs which are symmetrically arranged below the traction seat, the rear vehicle is separated from the front vehicle under the action of its own resistance after the car hook is uncoupled, at which time the proximity switches and the metal sensing sheets are beyond the sensing distance, so that it can be detected whether the traction device is uncoupled. The two sets of proximity switches arranged at the left and right symmetrical positions can prevent the proximity switch on one side of the curve from being beyond the sensing distance and misdetected.
[0029] When the traction device is uncoupled, the proximity switch detects that the car hook is uncoupled and transmits the signal to the rear vehicle, and the rear vehicle brakes to ensure that the rear vehicle does not rush out of the track.
[0030] The metal sensing sheets 10 are also elastically arranged on the traction assembly through springs 11. The traction assembly comprises a traction seat one 6, a traction rod 7, a traction pin 8 and a traction seat two 9; the car hook pin 5 and the metal sensing sheets 10 are arranged on the traction seat one 6, and the traction seat one 6, the traction rod 7 and the traction seat two 9 are sequentially connected in rotation through the traction pin 8.
[0031] The electric push rod 2 and the proximity switch 4 are also connected with the control console. Through the control console, the uncoupling operation can be conveniently controlled according to the uncoupling condition at a long distance, and the state of the car hook is fed back.
[0032] When the electric push rod 2 moves to the end of the stroke, the hook body 3 hooks or separates from the car hook pin 5.
[0033] The first carriage is further provided with a coupler mounting seat 1 for mounting the electric push rod 2 and a coupler pin 5.
[0034] The preferred embodiments of the present application have been described above with the preferred embodiments, but not for limiting the present application. For those skilled in the art, various modifications and variations can be made to the present application within the spirit and principle of the present application.
