Description

Technical Field

[0001] The utility model relates to the technical field of railway locomotives in smelters, and particularly relates to a quick detection device for the heavy hook in railway coupling operation. Background Technique

[0002] The locomotive and vehicle coupling operation refers to that the train shunter instantaneously judges according to the running speed of the locomotive train, the load and inertia of the locomotive train, the braking performance of the locomotive, and the distance between the locomotive and the vehicle to be coupled, and operates the shunting hand-held machine to issue shunting instructions such as "decelerate" and "couple". With the continuous development of enterprises, the production and operation rhythm has accelerated, and coupled with the change in the employment form, the shunters have gradually become laborers. During the locomotive and vehicle coupling operation, the situation of hitting the heavy hook occasionally occurs. The inspection scope of the locomotive equipment during shift handover is large, the local inspection is not intuitive, and the inspection time is relatively limited. It is very difficult for the on-duty driver to timely discover the hidden dangers caused by hitting the heavy hook in the previous shift, resulting in accidents during the subsequent operation of the locomotive and vehicle.

[0003] When the impact force is too large, the installation rivets or fastening screws of the components on the vehicle will be instantly subjected to a strong shearing force, resulting in damage to the components, and it is not easy to be discovered, leaving potential safety hazards for the subsequent locomotive transportation operation.

[0015] Referring to Figures 1-3 , this embodiment provides a quick detection device for double - hanging of heavy loads in railway coupling operations, including a hook frame. A coupler 5 is installed inside the hook frame, and the head of the coupler 5 extends towards one end. A horizontally arranged hollow tube 6 is installed at one end of the hook frame facing the coupler 5. A vertically arranged impact rod 7 is installed at the head of the coupler 5. A sliding seat 3 is connected to the rear end of the coupler 5, and the sliding seat 3 is slidably connected to the hook frame. Buffer pads are installed between both sides of the sliding seat 3 and the hook frame.

[0016] Preferably, the hook frame includes two fixed plates 1 with a certain distance between them. Slideways 2 are installed on the opposite sides of the two fixed plates 1. Sliders 8 are provided at the front and rear ends and both sides of the sliding seat 3. The sliders 8 are fixedly connected to the sliding seat 3 and are slidably connected to the slideways 2.

[0017] Preferably, buffer pads A9 are fixedly installed in the middle of both sides of the sliding seat 3, and buffer pads B4 are fixedly installed on the fixed plates 1. There is a certain distance between the buffer pad A9 and the buffer pad B4.

[0018] Preferably, a support plate is installed on each side at the front end of the hook frame, and the hollow tube 6 is installed between the two support plates. The support plates are provided with mounting holes corresponding to the hollow tube 6.

[0019] Preferably, the diameter of the hollow tube 6 is 1-3 cm, and the wall thickness is 1-2 mm. The working principle of the present invention is as follows: When the locomotive performs the coupling operation, the following situations may occur: 1. When the locomotive couples at a speed of less than 5 km / h, the hollow tube 6 is not completely compressed, and the hollow tube 6 is not deformed by the impact rod 7, so the destructive inspection of the heavy hook can be omitted. 2. When the coupling speed reaches 6-7 km / h, the steel hollow tube 6 will be deformed by the impact of the impact rod 7 and thus compressed to a certain extent. However, when observed from the outer end of the hollow tube 6, there will still be a certain light-transmitting gap inside the tube. At this time, a routine inspection of cracks, displacement, looseness or rubber seat tearing of the installation components is carried out, and the coupled vehicle is inspected; at the same time, a new hollow tube 6 is replaced and preparations are made for the next inspection. 3. When the coupling speed is greater than 7 km / h, the hollow tube 6 is strongly impacted by the impact rod 7 and is over-compressed. When observed from the outer end of the hollow tube 6, it is completely non-light-transmitting, and there are obvious impact marks on the impact seat of the vehicle body; at this time, a disassembly and comprehensive inspection of the installation components is required, the fasteners and rubber seats are replaced, and a further comprehensive inspection of the coupled vehicle is carried out; at the same time, a new hollow tube 6 is replaced and preparations are made for the next inspection.
