The guide rail 7 to be corrected is placed in the transport trolley 12 by means of a power device, such as a winch or a crane, for example, for pulling.
Utilize the utility model discloses the step of carrying out work goes into down:
as can be seen from fig. 8, the guide rail 7 to be corrected is first transported by means of the transport trolley 12 to the vicinity of the invention. The steel plate on one side is opened by the conveying trolley 12, and the guide rail 7 to be corrected is removed to the bearing steel plate of the electric lifting mechanism 6 by manual assistance, so that the guide rail 7 is ensured to be in two-point contact with the bearing steel plate and is kept stable.
Further, the guide rail 7 to be corrected is lifted to a position higher than the conduction limit rack 1 by using the electric lifting mechanism 6, an inclined stop block is arranged at the top of the electric lifting mechanism 6, and because the steel plate for bearing the guide rail 7 at the bottom of the electric lifting mechanism 6 is hinged, when the guide rail 7 reaches the top, the steel plate is in contact collision with the stop block and overturns; thereby realizing that the guide rail 7 falls on the horizontal roller 2 of the conduction limit rack 1.

Namely: one of the winches 8 is used for paying off the steel wire rope 10.3, and the other winch 8 is used for paying off the steel wire rope 10.3 with the same length. Through the movement, the guide rail 7 can reciprocate between the vertical rollers 3 and between the hydraulic mandril 4.4 and the reaction frame 4.3 of the correction platform 4 under the action of the winch 8.
The hydraulic ejector rod 4.4 is adjusted to continuously move towards the reaction frame 4.3 until the width of the hydraulic ejector rod is the same as that of the guide rail 7. In the movement process, the hydraulic ejector rods 4.4 account for 3 in total and need to be linked synchronously, so that the stress stability of the guide rail 7 in the correction process is realized.
Wherein, fixed pulley 10.2 are totally two and set up on same plumb line, and fixed pulley 10.2 middle part is provided with the pivot, and the pivot is fixed between two support body channel-section steels 10.1, and fixed pulley 10.2 and support body channel-section steel 10.1 constitute pulley yoke 10 jointly, and pulley yoke 10 fixes at the spacing rack of conduction 1 both ends and is located the central line of the spacing rack of conduction. The distance between the first vertical rollers 3.1 at the outermost side is 1.5-2 times of the width of the guide rail, and the width between the first vertical rollers 3.1 is gradually reduced to the width of the guide rail 7 along the direction moving towards the correcting platform 4.

Stress sheets of the hydraulic ejector rod 4.4 are arranged on the hydraulic ejector rod 4.4, and stress sheets in the second vertical roller 3.2 are arranged on a rotating shaft of the second vertical roller 3.2. The stress sheet feeds back the stress reading to the computer of the control cabinet 5 through a data line in real time, and in the process, the control cabinet 5 with the computer monitors the stress of the whole motion process at any time.
When the stress value of the stress sheet is zero, the computer sends a signal to the control cabinet 5, the control cabinet 5 controls the hydraulic ejector rod 4.4 to be pushed inwards through a circuit, at the moment, the stress of the hydraulic ejector rod 4.4 on the guide rail 7 is increased, and the reading of the stress sheet is increased. And then, the control cabinet 5 controls the winch 8 to work through a circuit, pulls the guide rail 7 to continuously reciprocate, and realizes the jacking correction of the guide rail 7 by the hydraulic ejector rod 4.4 until the reading fed back by the stress piece is zero. At this time, the control cabinet 5 gives a command to stop the operation of the hoist 8, and the movement of the guide rail 7 is stopped.
At this time, the control cabinet 5 continues to give a movement instruction to the hydraulic ejector rod 4.4, and repeats the above process, so that the hydraulic ejector rod 4.4 finally extrudes the guide rail 7 to be corrected until the width of the guide rail is the same as the width of the guide rail.
In order to ensure the correction quality of the guide rail 7, the stress of the hydraulic ejector rod 4.4 on the guide rail 7 is pushed for at least 3 times in the process.
And (5) until the final stress sheet feedback stress is zero, the correction of the guide rail 7 can be considered to meet the expected requirement.
