1. Shenyang stretcher inspection before use
(1) The hydraulic pumping station should be in good condition and the amount of oil should be sufficient. When refueling, the hydraulic oil must be filtered to prevent dust from blocking the oil circuit.
(2) The joints of oil cylinders and oil pipes must not be loose or leak oil.
(3) The inclined iron seat, tie rods and joints must not be damaged.
(4) The inclined iron base of this machine is ordinary type. When the pillow is not installed, the state is 75kg / m. For other types of rails, install the appropriate bearing beam. Each pad has a mark, ie 60 kg / m rail uses 60.
2. Start the hydraulic pump station (should run for about 5 minutes under no load), connect the cylinder tube, and then first extend the piston rods of the two cylinders to a position greater than the predetermined stretch length. The machine can stretch to 760mm at a time.
3. Place the tilted iron seat in the proper position to pull the two rails. Push the two beveled irons to the left and right (note that the left and right are not the same), and then push them into the inclined grooves of the beveled iron seat.
4. Assemble the cylinder and extension rod with the pins on the inclined iron seat. The recessed part of the extension bar faces the guide rail. During assembly, the two sides are assembled separately. You can temporarily remove the oil pipe on the other cylinder, start the oil pump, and adjust the piston. The rod is stretched to insert the pin.
5. Install the rail puller
Connect the oil channel and start the electric pumping station. The piston rod is fully extended. Place the clamp on the two guide rails, insert the wedge-shaped iron, place the cylinder and piston rod assembly, and place one end of the cylinder on the connected fish plate. On the rails. Adjust installation settings. The end face of the cylinder port should be approximately 40 mm longer than the end face of the guide rail. Then tighten the wedge iron at both ends. If the length of the guide rail exceeds 300 mm, the end face of the cylinder should be approximately 160 mm longer than the end of the guide rail.
6. Pressure release operation
After loosening the fastener, one must hammer the loosened guide rail every 50 meters. The electric pump station reverses and slowly pulls the two guide rails (note: as long as the slide rails are moving, do not increase the oil pressure too much. When the two slide rails knock down the appropriate slide rail joint, the electric pump station maintains a certain Pressure, tighten the bolts at the other end of the fish plate, tighten all the fish plate bolts, then pull out the rollers, tighten all the bolts at the bottom of the slide rail, replace the electric pump station, change the oil, and the clamp at one end loses its fixed state, Close the electric pump station, shake the other end to clamp the end with a hammer to lose its fixed state, and then remove the two-cylinder rail puller from the rail and complete the operation.
