A wire is connected between the power connection socket 203 and the suction electromagnet 201, and the wire is arranged inside the cable duct 202. Place the thermomechanical straightening device on the transport ship deck 1, connect it to an external power supply through the power connection socket 203 to energize it, and then the suction electromagnet 201 works, so that the bottom frame 2 can be adsorbed on the transport ship deck 1.

[0037] Among them; an auxiliary pressure plate 8 is placed on the upper surface of the transport ship deck 1 at the hole 101.

Both of the two movable connecting rods 604 are threadedly connected to the bidirectional screw rod 602. The movable connecting rods 604 are slidably connected to the mounting frame 601. When the lower end of the clamping head 7 passes through the central through hole 801 of the auxiliary pressure plate 8 and the hole 101, by rotating the handle 603, the bidirectional screw rod 602 can be driven to rotate synchronously. Under the limiting action of the mounting frame 601, the two movable connecting rods 604 can be realized to move horizontally along the bidirectional screw rod 602 and move away from each other.

[0040] Among them; two clamping heads 7 are provided. The two clamping heads 7 are respectively fixedly arranged at the lower ends of the two movable connecting rods 604.

[0042] Working principle: When performing thermal straightening on the deck 1 of a car carrier, first carefully detect and evaluate the deformed area of the deck. After determining the position and degree of the area to be straightened, while using the tooling, thermal heating can be combined. According to the material and deformation degree of the deck 1 of the carrier, control the heating temperature and time; place this thermal straightening device on the deck 1 of the carrier, connect and energize it through the power socket 203 and an external power cord. Then, the sucker electromagnet 201 works, enabling the bottom frame 2 to adsorb on the deck 1 of the carrier; before the clamping head 7 moves down through the hole 101, hold the handle rod 803, and through the L-shaped rod 802, place the auxiliary pressing plate 8 on the upper surface of the deck 1 of the carrier and make the through hole 801 of the auxiliary pressing plate 8 correspond to the hole 101. Then, pass the lower end of the clamping head 7 through the central through hole 801 of the auxiliary pressing plate 8 and the hole 101; when the lower end of the clamping head 7 passes through the central through hole 801 of the auxiliary pressing plate 8 and the hole 101, by rotating the handle 603, the bidirectional screw 602 can be driven to rotate synchronously. Under the limiting action of the mounting frame 601, the two movable connecting rods 604 can move horizontally along the bidirectional screw 602 and move away from each other. When the two movable connecting rods 604 move away from each other, they can drive the two clamping heads 7 to move synchronously and move away from each other. Thus, the edges of the hole 101 and the through hole 801 can be clamped into the notch 701 of the two clamping heads 7.

[0043] Furthermore, by driving the hand-held rotating rod 503 to rotate forward or backward, the hand-held rotating rod 503 will drive the driving screw 501 to rotate synchronously. When the driving screw 501 rotates and moves upward and contracts into the threaded hole of the connecting column 4, it can drive the driving clamping assembly 6 and the clamping head 7 to move upward and apply an upward pulling force; when the driving screw 501 rotates and moves downward, it can drive the driving clamping assembly 6 and the clamping head 7 to move downward and apply a downward pressure, thereby pulling back or flattening the deformed area of the deck 1 of the carrier. The operation is simple, time-saving, and labor-saving; when the deck is straightened to the expected flatness, keep the screw state to make the deck cool and take shape. Then, loosen the screw and remove the tooling. Finally, use a flatness measuring instrument, etc. to check the straightening quality.
