During the operation, the user drives the carrier to move in the carriage through the traverse gear motor. When the traverse gear motor reverses, the gear rotates counterclockwise, and the gear and the rack mesh. At this time, the carrier slides outwards from the carriage under the drive of the gear.
When part of the carrier slides out of the carriage, the user controls the two multistage cylinders at the rear to stretch out until the omni-directional wheels touch the ground. Continue to move the carrier out of the carriage until the cylinder sleeve at the front of the carrier is also outside the carriage. At this time, the user controls the two multistage cylinders at the front to stretch out 2 until the omni-directional wheels touch the ground. At this time, the four omni-directional wheels touch the ground, and the carrier is positioned under the support of the multi-stage cylinders.

Working principle: When the special loading device for petroleum pipeline transportation is used, the motor terminal block 23 and the cylinder terminal block 27 can be powered on first, the traverse gear motor 4 and the pull-back gear motor 6 are connected in parallel with the motor terminal block 23, the two multistage cylinders 11 at the front are grouped into one set, the two multistage cylinders 11 at the rear are grouped into another set, and these two sets of multistage cylinders 11 are connected in parallel with the cylinder terminal block 27. During the operation, the user drives the carrier 8 to move in the carriage 1 through the traverse gear motor 4. When the traverse gear motor 4 reverses, the gear 5 rotates counterclockwise, and the gear 5 and the rack 25 mesh. At this time, the carrier 8 slides outwards from the carriage 1 6 under the drive of the gear 5. When part of the carrier 8 slides out of the carriage 1, the user controls the two multistage cylinders 11 at the rear to stretch out until the omni-directional 102/49 wheels 12 touch the ground.
Continue to move the carrier 8 out of the carriage 1 until the cylinder sleeve 10 at the front of the carrier 8 is also outside the carriage 1. At this time, the user controls the two multistage cylinders 11 at the front to stretch out until the omni-directional wheels 12 touch the ground.
At this time, the four omni-directional wheels 12 touch the ground, and the carrier 8 is positioned under the support of the multi-stage cylinders 11. At this time, other traction devices can be used to pull back the carrier 8 to make it completely separate from the carriage 1, and then the user controls the four multistage cylinders 11 to retract until the omni-directional wheels 12 retract back into the cylinder sleeve 10. At this time, the carrier 8 is placed on the ground to facilitate the loading personnel to put the petroleum pipeline directly on the carrier 8. All the multistage cylinders 11 are electrically controlled cylinders.
The electrically controlled cylinder is widely used in the field of hydraulic press and lift.
The technology for controlling it is mature and reliable, so it can be used by our device directly.
At the same time, the roller 30 on the carrier 8 can rotate.
When the pipe is placed on the carrier 8, the staff can push and pull the pipe to make it in the right position on the carrier 8. The baffle 13 acts as a barrier to prevent the pipe from sliding out of the carrier 8. The baffle 13 with heightening structure can be used for the baffle in this device.
Such a structure is very common in the field of cargo truck.
The baffle with conventional heightening structure can be used in this device.
After the pipeline is installed, the user controls the multistage cylinder 11 to stretch out to make the height of the carrier 8 the same as that of the carriage 1. After that, the user drives the reel 7 by pulling back the gear motor 6, and the reel 7 rotates back to make the cable 9 pull the carrier 8 toward the front of the carriage 1. When one end of the carrier 8 is propped against the carriage 1 and the gear 5 is meshed with the rack 25, the user controls the two multistage cylinders 11 at the front to retract.
After the retraction, the user can control the traverse gear motor 4 to rotate forward.
The clockwise rotating gear 5 makes the carrier 8 retract into the carriage 1. When most of the carrier 8 is on the carriage 1 and the center of gravity is on the carriage 1, the user retracts the two multistage cylinders 11 at the rear, and then retracts the carrier 8 back into the carriage 1 completely through the traverse gear motor 4. When the connector 24 touches the limit switch 22, the traverse gear motor 4 will stop.
Limit switch 22 is widely used in the field of mechanical equipment, which can be used in this device directly.
After the carrier retracts, the user tightens the pipe stack through the fixing cable 15 to prevent the pipes from scattering and falling.
The fixing cable 15 can fit with the positioning bolt 17 through the ferrule 34, and can also be wound on the positioning bolt 17 according to the number of pipes to play the role of tension.

Such a structure is very common in the field of cargo truck.
The baffle with conventional heightening structure can be used in this device.
After the pipeline is installed, the user controls the multistage cylinder to stretch out to make the height of the carrier the same as that of the carriage.
After that, the user drives the reel by pulling back the gear motor, and the reel rotates back to make the cable pull the carrier toward the front of the carriage.
When one end of the carrier is propped against the carriage and the gear is meshed with the rack, the user controls the two multistage cylinders at the front to retract.
After the retraction, the user can control the traverse gear motor to rotate forward.
The clockwise rotating gear makes the carrier retract into the carriage.
When most of the carrier is on the carriage and the center of gravity is on the carriage, the user retracts the two multistage cylinders at the rear, and then retracts the carrier back into the carriage completely through the traverse gear motor.
When the connector touches the limit switch, the traverse gear motor will stop.
Limit switch is widely used in the field of mechanical equipment, which can be used in the present devicedirectly.
After the carrier retracts, the user tightens the pipe stack through the fixing cable to prevent the pipes from scattering and falling.
The fixing cable can fit with the positioning bolt through the ferrule, and can also be wound on the positioning bolt according to the number of pipes to play the role of tension. 11
