[0005] The locking rod includes a vertical rod, a pin, a plate hook and a protrusion. The protrusion is installed on the upper part of the vertical rod, and a threaded hole is vertically opened in the middle of the protrusion. A plate hook is installed on each side of the lower end of the vertical rod, and a pin is provided on both sides of the vertical rod to slide along the slide groove.

[0006] The screw rod is vertically arranged in the strip hole, and the lower part of the screw rod is screwed to the threaded hole on the protrusion;

[0007] The turntable is a disc structure and is fixed on the top of the screw rod.

[0008] As a supplement to the technical solution described in the present invention, the guide plate is a trapezoidal steel plate structure, the surfaces where the long sides and short sides are located are both vertical surfaces, and the surface where the short side is located is connected to the connecting plate.

[0009] As a supplement to the technical solution described in the present invention, the connecting plate is a rectangular steel plate structure, and a plurality of bolt holes are provided on both sides of the connecting plate.

[0012] As a supplement to the technical solution described in the present invention, the pin is a cylindrical structure, and the side surface of the short side of the vertical pole is provided with bolt holes adapted thereto, and the spacing of the bolt holes is consistent with the spacing of the slide grooves.

[0013] As a supplement to the technical solution described in the present invention, the protrusion is a rectangular block structure, and the protrusion is installed on the end face where the long side of the top of the vertical pole is located.

[0014] A method for using the locking mechanism of an offline centering device of a tension and leveling machine, the specific operating steps are as follows:

[0015] Step 1: Assemble the locking mechanism;

[0016] S1. Install the locking rod: Place the vertical pole between the two guide plates, with the plate hook facing the connecting plate of the locking support. Align the bolt hole on the short side of the vertical pole with the slot opening on the guide plate. Then, insert the pin through the slot opening and install it into the bolt hole on the side of the vertical pole.

[0017] S2. Install the turntable: Install the screw into the circular hole in the middle of the turntable and weld it together. Then pass the screw through the strip hole on the top plate of the locking support. When the bottom of the screw contacts the protrusion of the locking rod, rotate the turntable clockwise. At this time, the thread on the screw engages with the thread in the center hole of the protrusion. Continue to rotate the turntable to drive the screw through the center hole of the protrusion and move downward until the turntable contacts the top plate of the locking support. At this time, the pin on the locking rod is located at the bottom of the slide slot and cannot move.

[0018] Step 2: Install the locking mechanism on the centering device;

[0019] First, machine the bolt holes on the side of the centering device beam, and install the assembled locking mechanism on the centering device beam so that the connecting plate of the locking support is close to the centering device beam;

[0020] Step 3: Install the centering device on the tension and leveling machine;

[0021] Hoist the assembled centering device and locking mechanism to the top of the tension and leveling machine;

[0022] Step 4: The locking mechanism locks the centering device;

[0023] S1. Rotate the turntable counterclockwise to drive the screw rod to rotate together. An upward force is generated on the thread of the protrusion that engages with the screw rod, driving the locking rod to move upward. Since the pin is installed on the locking rod through the slide groove, the pin and the locking rod are an integral structure. During their upward movement, they are constrained and guided by the slide groove and can only move upward along the slide groove.

[0024] S2. During the rotation, the turntable drives the lead screw to move from one end of the strip hole on the top plate to the other end; when the pin moves to the inflection point where the long side and the short side of the L-shaped slide groove intersect, check that the plate hook is just under the crossbeam of the straightening machine and there is no interference, continue to rotate the turntable counterclockwise and lift the locking rod upward until the plate hook is in full contact with the crossbeam of the straightening machine, then continue to rotate the turntable to apply the same pre-tightening force to the locking mechanisms installed at both ends of the crossbeam of the centering device to complete the fixation of the centering device.

[0025] Beneficial effects: The present invention relates to a locking mechanism for an offline centering device of a tension and leveling machine and a method for using the same, which has the following advantages:

[0026] 1. Firmly fixed, the locking mechanism is located in the middle of the centering device beam, and tightening force is applied at both ends of the centering device for reliable fixation;

[0027] 2. Flexible installation. The movable locking rod allows the locking mechanism to be installed together with the centering device, avoiding interference.

[0048] A method for using the locking mechanism of an offline centering device of a tension and leveling machine, the specific operating steps are as follows:

[0049] Step 1: Assemble the locking mechanism 1;

[0050] S1. Install the locking rod: Place the vertical rod 31 between the two guide plates 21, with the plate hook 33 facing the connecting plate 23 of the locking support 2. Align the bolt hole on the short side of the vertical rod 31 with the opening of the slide groove 22 on the guide plate 21. Then, insert the pin 32 through the opening of the slide groove 22 and install it into the bolt hole on the side of the vertical rod 31.

[0051] S2. Install the turntable: Install the screw rod 4 into the circular hole in the middle of the turntable 5 and weld them together. Then, pass the screw rod 4 through the strip hole 25 on the top plate 24 of the locking support 2. When the bottom of the screw rod 4 contacts the protrusion 34 of the locking rod 3, rotate the turntable 5 clockwise. At this time, the threaded screw rod 4 is engaged with the threaded screw rod in the center hole of the protrusion 34.
