Description

Railway train hook and slow device dismantling machine

technical field

The invention belongs to vehicle maintenance equipment, and in particular relates to a dismantling and installing device for a railway train coupler and buffer device.

Background technique

The coupler buffer device is a component that connects the locomotive and the vehicle or transmits the longitudinal traction force and eases the impact force of the train. It is composed of a coupler frame, an ST buffer and a slave plate, and the slave plate and the ST buffer are installed in the coupler frame in sequence; The coupler frame is installed in the traction beam at both ends of the car body chassis, and is limited by the front plate base and the rear plate base in the transverse direction, and supported by the coupler frame support plate and the hook joist in the longitudinal direction; the coupler tail is inserted into the coupler tail In the frame, the rear end leans against the slave plate, and a waist-shaped hole is arranged near the tail of the coupler, and the coupler is fixed by a coupler pin and a U-shaped clip. Force transmission process during traction: coupler-coupler pin-coupler frame-ST buffer-slave plate-front plate seat-drawing beam; force transmission process in impact compression state: coupler-slave plate-ST buffer-rear From plate base - tow beam.

According to maintenance regulations and safe driving requirements, the locomotive coupler must be regularly removed from the draw beam, disassembled for maintenance, and then installed on the vehicle body. Since the pressure of the ST buffer is set at 40 tons when it leaves the factory, and its size matches the size of the coupler frame. When dismounting, the elastic force released by the internal spring of the ST buffer acts on the front and rear slave plate seats in the draw beam, and a large friction force is generated on the joint surface of the slave plate and the front slave plate seat, which makes the ST buffer unable to be removed, and then The hook-tail frame also cannot be removed. Previously, the cutting method was used on site. Due to the narrow space in the traction beam and the obstruction of the front slave board seat and the coupler frame, the cutter could not enter the cutting board. We had to cut off the coupler frame first, and then cut off the slave board. If you accidentally cut the thrust cone of the ST buffer, the ST buffer will be scrapped, the labor intensity of the welder will be high, there will be safety hazards in cutting thick steel plates, and the maintenance cost will be high. When installing the repaired ST buffer, it also needs to be compressed before it can be put into the coupler frame, which requires special installation tools.

At present, there are two types of dismantling and assembling machines for railway train hook and buffer devices: one is a forklift-type hook and buffer device dismantling tool, which is composed of a compressed oil cylinder, a pair of compression plates and a frame, and the frame is fixed on the fork of the forklift. The compression cylinder is connected with the compression plate and fixed on the frame. Using the principle of leverage, the compression plate compresses the buffer and removes or installs it from the locomotive. The forklift provides pressure oil and moves vertically, horizontally, and up and down. The existing defects are: 1) The purchase price of forklifts is high, the maintenance cost is high, and the production cost is increased; 2) The requirements for the use of the site are relatively high, and a large and unobstructed work site is required; 3) Forklifts need to be operated by professionals, and special personnel are required to direct the operation , a large waste of human resources, and increased labor costs; 4) During the movement of the forklift, it is easy to collide with the vehicle, which will damage both the forklift and the vehicle.

One is a wheel-rail type hook and buffer device disassembly and assembly tool, which is composed of a car body, a traveling mechanism, a bracket, a hydraulic system and an electric control system. And the bracket, the electric control system is electrically connected with the hydraulic system, and the hydraulic system controls the work of the bracket. After the buffer is compressed by the principle of leverage, the hook buffer device is removed from the locomotive or installed. The existing defects are: 1) the design and structure of the device is complex, the cost of components is high, and the production cost is increased; 2) there is a limitation in the use of the site, and trenches are required to work; 3) the maneuverability is poor and the work efficiency is low.
