A hook lifting device

Abstract

A hook lifting device for a vehicle coupler, including a rod lifting device. There are two lifting rod devices, and also includes an interlocking device, a U-shaped rod, and a support. The middle position of the U-shaped rod is connected to the An interlocking device, the two ends of the U-shaped rod are respectively fixedly connected to the two lifting rod devices. The U-shaped bar at the middle position is connected to the lifting bar devices on both sides to act as a linkage, and the interlocking device is clamped and connected with the coupler ejector bar on the coupler. When the vehicle needs to be uncoupled, turn any lifting rod device on both sides to a suitable position, and the lifting rod device drives the interlocking device through the support so that the coupler ejector rod performs a fan-shaped arc rotation, and the uncoupling action can be completed. The coupler lifting device only needs to be operated on one side to realize linkage, which eliminates the potential safety hazard when the operator who understands the hook and the hook is interspersed between the two heads. The device is left-right symmetrical, simple in structure and quick to install.

Description

technical field [0001] The invention relates to the field of rail locomotives, in particular to a coupler lifting device. Background technique [0002] The coupler is a vehicle component used to realize the connection between the locomotive and the vehicle or between the vehicle and the vehicle, transmit the traction force and the impact force, and keep a certain distance between the vehicles. According to the opening method, the coupler is divided into two types: upper action type and lower action type. The one that is opened by the lifting mechanism on the upper part of the coupler head is called the upper action type, and most trucks generally use this type; the one that is opened by means of the action of the push lever at the lower part of the coupler head is called the lower action type, and this type is usually used by passenger cars. The HXD3 series locomotives use the No. 13 down-acting coupler to connect the headstock and the carriage. The original design uses a s...

CN 201310639914.8 provides a locomotive coupler uncoupling device. In order to prevent the automatic uncoupling of the coupler due to the free jump of the lifting rod when the locomotive is running in a complex environment, it is mainly composed of a hook lifting rod and a cylinder device. It can only realize the unhooking action of the lifting rod on one side. Once the two heads are docked, the operator needs to intersperse between the two heads that are connected to realize the hooking operation of the two heads, which poses personal safety hazards.

CN201310536958.8 provides a kind of uncoupling device for railway vehicles, which is aimed at the automatic coupler of the knuckle tongue type, which is composed of a transmission mechanism and a locking and positioning mechanism. When the hook bar is on the other side of the vehicle, it needs to pass through the middle of the locomotive, which is dangerous
