Description
Technical Field
The invention belongs to the technical field of railway vehicle couplers, and particularly relates to a device for preventing incorrect coupler uncoupling of an automatic coupler.
Background
With the development of technology, the application of the tight-lock automatic coupler is more and more common, and the tight-lock automatic coupler is adopted among the train units in order to facilitate the decompiling of the whole train unit. The coupling and the de-knitting of the tight-lock automatic coupler are very convenient, and the operation is simple. Therefore, if someone accidentally operates the uncoupling device of the automatic coupler, the automatic uncoupling of the coupler can be caused, so that virtual connection between train units is caused, and if the automatic uncoupling device cannot be found in time, the automatic uncoupling device finally causes the uncoupling of the train during operation, and even casualties.
At present, the uncoupling device of the unit tight-lock type automatic coupler used in the market is not protected or is simply protected in a separating way, so that misoperation cannot be well prevented. Therefore, a better structure is needed to be further designed to prevent the possibility of misoperation and ensure the safe operation of the whole subway vehicle.
Disclosure of Invention
The invention aims to develop a novel metro vehicle tight-lock type automatic coupler anti-misunhooking device to prevent the automatic coupler from misunhooking, thereby ensuring the safety of metro vehicles.
In order to achieve the above object, the present invention provides a railcar tight-lock type automatic coupler anti-misunderstanding device, characterized in that: the movable part comprises an unhooking handle and a movable end unhooking rope, one end of the movable end unhooking rope is connected with the C-shaped lock catch, and the other end of the movable end unhooking rope is connected with the unhooking handle through the U-shaped lock catch; the fixed part comprises a fixed end unhooking rope and an unhooking pull rod, one end of the fixed end unhooking rope is connected with the C-shaped lock catch of the movable part, the other end of the fixed end unhooking pull rod is connected with the unhooking pull rod, the other end of the unhooking pull rod is connected with a main shaft of the whole car coupler, meanwhile, the unhooking pull rod is connected to a coupler head of the car coupler through a fixed cylindrical pin in clearance fit with the unhooking pull rod, and the top of the fixed cylindrical pin is arranged in a limiting hole in a supporting flat plate. Because the uncoupling pull rod is connected with the coupler spindle and is in clearance fit with the fixed cylindrical pin, the fixed cylindrical pin limits the rotation of the uncoupling pull rod and prevents the uncoupling operation from being mistaken.
The fixed end unhooking rope passes through the fixed sleeve ring to be connected with the C-shaped lock catch of the movable part, and the fixed sleeve ring is fixed on the car coupler to prevent the unhooking rope from shaking around when the car moves.
In order to prevent the fixing cylindrical pin from being accidentally disengaged, an anti-disengagement split pin is arranged on the fixing cylindrical pin and is positioned below the through passage support plate.
The fixed end unhooking rope is connected with the C-shaped lock catch of the movable part by the fixed end unhooking rope penetrating through the C-shaped lock catch to be folded back and then locked through the lock catch.
Compared with the prior art, the invention has the following advantages and progresses:
1. the final action structure of uncoupling the car coupler and the uncoupling operation structure are decomposed into a whole, so that the problem of misoperation is fundamentally solved.
2. From the management angle, the rope that unhook was held to the expansion end is listed as specialized tool, and the special messenger operates, strengthens the management and control.
3. The double protection fixes the unhooking pull rod in the traditional free state through a double structure, and avoids the possibility of artificial damage to a certain extent.

Detailed Description
Referring to fig. 1-3, the specific embodiment of the invention comprises a movable part 1 and a fixed part 2, wherein the movable part comprises an unhooking handle 1-1, a movable end unhooking rope 1-2, a C-shaped lock catch 1-3 and a U-shaped lock catch 1-4, one end of the movable end unhooking rope 1-2 is connected with the C-shaped lock catch 1-3, and the other end is connected with the unhooking handle 1-1 through the U-shaped lock catch 1-4; the fixed part comprises a fixed end unhooking rope 2 and an unhooking pull rod 4, one end of the fixed end unhooking rope 2 is connected with a C-shaped lock catch 1-3 of the movable part, the other end of the fixed end unhooking rope 2 is connected with one end of the unhooking pull rod 4, the other end of the unhooking pull rod 4 is connected with a main shaft 9 of the whole car coupler, meanwhile, a fixing cylindrical pin 5 penetrates through the unhooking pull rod 4 to be connected with one end of the fixed end unhooking rope to be connected to a car coupler head, and the top of the fixing cylindrical pin 5 is arranged in a limiting hole 8 in a through passage supporting flat.
The fixed end unhooking rope 2 penetrates through the fixed lantern ring 3 to be connected with the C-shaped lock catches 1-3 of the movable part, and the fixed lantern ring 3 is fixed on the car coupler to prevent the unhooking rope from shaking everywhere when the car moves.
The upper part of the fixed cylindrical pin 5 is provided with a hole, and an anti-drop cotter pin 6 is arranged in the hole to prevent the unhooking pull rod from being accidentally dropped out.
The fixed unhooking rope 2 is connected with the C-shaped lock catches 1-3 of the movable part through the fixed unhooking rope 2 passing through the C-shaped lock catches 1-3 to be folded back and then locked through the lock catches 10, and the connection is safe and reliable.
In the invention, the fixed cylindrical pin 5 passes through the upper through passage support plate 7 and then passes through the lower unhooking pull rod 4 to be finally screwed into the hook head main body, so that the unhooking pull rod 4 cannot be rotated to unhook by pulling the unhooking rope without taking out the fixed cylindrical pin 5.
The uncoupling pull rod is connected with the coupler spindle and is in clearance fit with the fixed cylindrical pin. Namely, the fixed cylindrical pin limits the rotation of the unhooking pull rod. As long as the cylindric lock is pulled out, just can rotate the unhook pull rod, need to unhook the rope with the expansion end in addition and link to each other with the stiff end, the pulling is unhook the rope and just can unhook. The possibility of human damage is avoided to a certain extent by double protection.
