Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of train control, in particular to an automatic unhooking and hooking device for a train. Background Art
[0002] Trains are the most important mechanical means of transportation in human history. In the early days, they were called steam locomotives, also called trains. They run on independent tracks. Railway trains can be divided into freight cars and passenger cars according to the load. There are also passenger and freight cars that carry both. Many continuous vehicles generally refer to trains, especially trains composed of traction locomotives and freight or passenger cars.
[0003] In the existing technology, when connecting electric locomotives and freight trucks, most of the connection methods are through consuming a lot of manpower. This method is not only labor-intensive, but also time-consuming. If there is bad weather, using manpower to use the device to perform the connection work increases the difficulty of the operator's work and reduces practicality. Utility Model Content
[0004] The utility model aims to solve the disadvantages and proposes an automatic unhooking and hooking device for trains.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A train automatic hooking and unhooking device comprises a supporting base, wherein a pin is provided on both upper and lower sides of the inner wall of the supporting base, a main hook body is sleeved on the outer surface of the upper pin, and an auxiliary hook body is sleeved on the outer surface of the lower pin, a hook body reset spring is provided on the lower surface of the main hook, and the lower end of the hook body reset spring is connected to the left edge of the upper surface of the auxiliary hook body;
[0007] A second pin is arranged at the bottom position of the left side of the inner wall of the supporting base, and a hook body linkage supporting block is sleeved on the outer surface of the second pin.
[0008] Preferably, an unlocking slider is provided on the left side of the main hook body, and a stopper is provided on the left side of the unlocking slider.
[0009] Preferably, a connecting pin is provided at the bottom position of the inner wall of the unlocking slider, and a cylinder is fixedly connected to the middle position of the lower surface of the connecting pin.
[0010] Preferably, a load-bearing block is fixedly connected to the lower surface of the cylinder, and a cross joint is provided on the right side of the lower surface of the load-bearing block.
[0011] Preferably, a pin shaft three is arranged on the upper side of the outer surface of the cross link joint, and a pin shaft four is arranged on the lower side of the outer surface of the cross link joint.
[0012] Preferably, a shell is provided on the left side of the supporting base, and a mounting plate is provided at the middle position of the left side of the shell.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] When the device is used to connect the electric locomotive and the freight car, under the action of the hook body reset spring, the main hook body and the auxiliary hook body always remain in a closed state. When connected with the freight car, the electric locomotive reverses, so that the hook body hits the traction pin of the freight car, and the oblique section of the hook body is subjected to force, so that the main and auxiliary hook bodies compress the hook body reset spring, so that the traction pin enters the inner cavity and is stuck in the groove between the main hook body and the auxiliary hook body. The main hook body and the auxiliary hook body are reset under the action of the hook body reset spring, the electric locomotive stops reversing, and then changes direction to move forward. The traction pin enters the arc groove of the main hook body under the action of the auxiliary hook body, thereby completing the automatic connection between the electric locomotive and the freight car, avoiding a lot of manpower to perform the connection operation, reducing the workload of the operator, and improving the practicability of the device.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Embodiment 1

[0025] In the existing technology, when connecting electric locomotives and freight trucks, most of the connection methods are through consuming a large amount of manpower. This method not only consumes huge manpower, but also consumes a lot of time. If bad weather occurs during the docking process, continuing to use manpower to use the device to perform the connection work is likely to affect the docking work, increase the difficulty of the operator's work, and then reduce practicality.
[0026] When the device is used to connect the electric locomotive and the freight car, under the action of the hook body reset spring 5, the main hook body 3 and the auxiliary hook body 4 always remain in a closed state. When hooking with the freight car, the electric locomotive reverses, so that the main hook body 3 and the auxiliary hook body 4 hit the traction pin of the freight car, and the hook body oblique section is stressed, so that the main hook body 3 and the auxiliary hook body 4 compress the hook body reset spring 5, so that the traction pin enters the inner cavity and is stuck in the groove between the main hook body 3 and the auxiliary hook body 4. The main hook body 3 and the auxiliary hook body 4 are reset under the action of the hook body reset spring 5, the electric locomotive stops reversing, and then changes direction to move forward. The traction pin enters the arc groove of the main hook body 3 under the action of the auxiliary hook body 4, thereby completing the automatic connection between the electric locomotive and the freight car, thereby avoiding the consumption of a large amount of manpower for traction operation and reducing the workload of the operator;
[0027] When the electric locomotive needs to be uncoupled from the freight car, first the electric locomotive changes from forward to reverse, so that the traction pin enters the arc groove of the base body, and then stops. Secondly, the rotary button is started to the uncoupling gear, and the cylinder 11 drives the unlocking slide block 8 to move along the stop block 9. On the one hand, the unlocking slide block 8 brings the main hook body 3 to overcome the resistance of the hook body return spring 5 to open the main hook body 3. At the same time, the unlocking slide block 8 hits the hook body linkage support block 7 on the other hand, driving the auxiliary hook body 4 to overcome the resistance of the hook body return spring 5, thereby opening the auxiliary hook body 4. Once again, the electric locomotive is started to move forward to complete the automatic uncoupling of the electric locomotive and the freight car. Finally, the button is turned to the reset gear, and the cylinder 11 drives the unlocking slide block 8 to reset, so that the main hook body 3 and the auxiliary hook body 4 are in a closed working state under the action of the hook body return spring 5, so as to facilitate the next step of automatic coupling with the freight car, thereby improving the practicality of the device.
[0028] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
