Technical Field
[0001] The utility model belongs to the technical field of traffic facilities, in particular to a self-detaching vehicle coupler. Background Art
[0002] A train, also known as a railway train, refers to a vehicle running on a railway track, usually composed of multiple carriages. Its huge transportation capacity makes it one of the important modern transportation tools for humans. It is mainly used to carry people and goods. Derailment is one of the accidents that may occur during the operation of a train. It is mainly caused by wheel problems, railway equipment problems, and driver errors. In order to prevent the derailment of carriages from hindering the normal use of other trains, the carriages are usually re-tracked with the help of rescue equipment. When the carriage is overturned or the line is damaged and re-tracking is not possible, the carriage needs to be pulled over to the outside of the railway boundary to quickly open the route. The conventional method uses track cranes and re-tracking The rescue operation is carried out by pulling, lifting, hoisting and turning over the rescue equipment, recovery equipment, locomotive or other rescue power equipment. When the rescue operation is carried out by hoisting, a rail crane running on the rail is usually used as a hoisting power machinery. One end of the steel rope used for hoisting is set on the hook in the rail crane, and the other end of the steel rope is fixed to the hook. The hook is hung on the hook frame on the car. When lifting, the hook on the rail crane drives the steel rope to move, thereby driving the hook to move and the hook frame to move, and finally achieving the purpose of moving the car. However, the hook of the prior art needs manual operation to separate the hook from the hook frame after the lifting is completed, which is more troublesome to operate.
[0003] For this reason, we provide a kind of self-release type coupler, in order to solve the above-mentioned problem. Utility Model Content
[0004] The utility model aims to provide a self-detaching coupler, which can tilt clockwise under the action of a counterweight plate when releasing the hook frame so as to utilize the effect of gravity to separate the coupler body from the hook frame, thereby solving the problem that the coupler of the prior art needs manual operation to separate the coupler from the hook frame after lifting, which is a relatively troublesome operation.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model discloses a self-detachable vehicle coupler, comprising a vehicle coupler body, the vehicle coupler body comprising a hook sleeve, connecting plates are fixed to the front and rear sides of the lower end of the hook sleeve, a connecting sleeve is fixed to the lower end of the connecting plate, a hook frame is arranged on the left wall of the two connecting plates, a load-bearing plate is arranged on the lower wall of the hook frame, and the load-bearing plate is located between the two connecting plates, a boss is fixed on the load-bearing plate corresponding to the left side of the hook frame, a counterweight plate is fixed on the upper wall of the right side of the load-bearing plate, a connecting rod is penetrated on the lower right side of the load-bearing plate, and the front and rear ends of the connecting rod pass through the connecting sleeve and extend to the outside of the connecting sleeve.
[0007] The utility model is further configured that a rope hole is opened at the middle position of the hook sleeve, a through hole is opened at the middle position of the connecting sleeve, and the connecting rod is located in the through hole.
[0008] The utility model is further configured that a baffle is fixed to the rear end of the connecting rod, a through hole is radially opened at the front end of the baffle, and a limit clamp is arranged inside the through hole.
[0009] The utility model is further configured such that a mounting hole is provided at the lower right side of the load-bearing plate, and the connecting rod is located in the mounting hole, and a rounded corner is provided at the lower left end of the load-bearing plate.
[0010] The utility model is further configured such that the boss is chamfered at one end close to the hook frame, and the distance between the axis of the connecting rod and the lower end of the outer periphery of the hook sleeve is smaller than the distance between the axis of the connecting rod and the upper surface of the counterweight plate.
[0011] The utility model is further configured such that the connecting rod, the mounting hole and the through hole are all arranged in a circular shape.
[0012] The utility model has the following beneficial effects:
[0013] The utility model is provided with a connecting rod, a counterweight plate, a load-bearing plate and a connecting sleeve, and the load-bearing plate and the counterweight plate can rotate relative to the connecting sleeve through the connecting rod. When the hook frame is released, the center of gravity is located on the right side of the connecting plate under the action of the counterweight block. At this time, the counterweight block will rotate clockwise to form an inclined state. At this time, the hook frame slides upward along the left wall of the connecting plate until the hook frame is separated from the hook body to achieve the self-separation effect of the hook body and the hook frame. Compared with the prior art, there is no need to manually separate the hook from the hook frame, and the operation is more convenient and labor-saving. This solves the problem that the hook in the prior art needs to be manually operated to separate the hook from the hook frame after lifting is completed, and the operation is more troublesome.
