DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] The front, back, left, right, top and bottom in the embodiments are described with reference to the base surface. Figure 1 The utility model provides a technical scheme: Figures 1-5

[0023] It should be noted that, combined with Figure 1 , Figure 2 and Figure 3 ​As shown, the telescopic bracket 3 comprises a hinged frame 31 and a movable frame 32, the lower end of the hinged frame 31 is rotatably installed in the corresponding mounting slot 21 through a rotating shaft, a fixed plate 311 is fixedly installed on the side of the hinged frame 31 close to the hydraulic telescopic column A5, the fixed plate 311 is rotatably connected with the hydraulic telescopic column A5, an insertion slot is formed at the top end of the hinged frame 31, the bottom end of the movable frame 32 is insertedly installed in the insertion slot, the hinged frame 31 and the movable frame 32 are both H-shaped, and a hydraulic telescopic column B33 is fixedly installed between the hinged frame 31 and the movable frame 32, and a lifting roller 34 is rotatably installed at the top end of the movable frame 32.

[0024] The telescopic movement of the hydraulic telescopic column B33 can drive the movable frame 32 to move in the insertion slot, so as to increase or reduce the length of the telescopic bracket 3 as a whole, and the telescopic movement of the hydraulic telescopic column A5 can drive the telescopic bracket 3 to overturn, so as to change the lifting position of the telescopic bracket 3 on the arched steel plate.

[0025] A servo motor A7 is fixedly installed on the front surface of any movable frame 32, the output end of the servo motor A7 is fixedly connected with the front end of the corresponding lifting roller 34 through a shaft coupling, the servo motor A7 is a pulse type forward and reverse motor, which is connected with an external controller and an external power supply, the external controller controls the forward and reverse rotation of the servo motor A7 by sending pulse signals to the servo motor A7, and the servo motor A7 can drive the lifting roller 34 to rotate after being started, when the top arched steel plate is placed on the two lifting rollers 34 by an external travelling crane hoist, but has not been separated from the external travelling crane hoist, the rotating lifting roller 34 can be used to drive the top arched steel plate to move to the left or right side to adjust the placement position, so that the placement position is more convenient and labor-saving.

[0026] In order to avoid that the top arched steel plate moves forward and backward to separate from the lifting roller 34 during placement, two shielding discs 341 are fixedly installed on the outer surface of the lifting roller 34, the top arched steel plate can be limited by the shielding discs 341 on the front and back sides to ensure the stability during placement.

[0027] As shown in Figure 4 , two fixed blocks 41 are fixedly installed on the upper surface of the support frame 4 in front of and behind symmetry, the clamping mechanism 6 comprises a positive and negative tooth bidirectional screw 61 and a servo motor B62, the positive and negative tooth bidirectional screw 61 is rotatably installed between the two fixed blocks 41, the servo motor B62 is fixedly installed on the upper surface of the support frame 4, and the output end of the servo motor B62 is fixedly connected with the front end of the positive and negative tooth bidirectional screw 61 through a shaft coupling, two clamping plates 63 are symmetrically screwed on the outer surface of the positive and negative tooth bidirectional screw 61, and the clamping plates 63 are slidably connected with the support frame 4.

[0028] Servo motor B62 is a pulse-type forward and reverse motor. It is connected to an external controller and an external power supply. The external controller controls the forward and reverse rotation of servo motor B62 by sending pulse signals to it. Servo motor B62 can drive the bidirectional screw 61 with forward and reverse threads through a coupling, thereby driving the two clamping plates 63 to move inward or outward synchronously. When the two clamping plates 63 move inward synchronously and fit against the placed top arch steel plate, the clamping mechanism 6 clamps and fixes the top arch steel plate between the two lifting rollers 34.

[0029] Finally, to ensure the stability of the lifting frame 2 during lifting, such as Figure 1 As shown, four guide rods 12 are fixedly installed on the upper surface of the movable base 1. The lifting frame 2 is vertically slidably installed between the four guide rods 12. A hydraulic telescopic column C11 is fixedly installed between the lower surface of the lifting frame 2 and the upper surface of the movable base 1. The lifting frame 2 is lifted and lowered by extending the hydraulic telescopic column C11. The stability of the lifting frame 2 during the lifting and lowering process is ensured by the four guide rods 12.

[0030] Working principle: Before use, move the entire device to the installation position of the arch steel plate. During use, extend the hydraulic telescopic column C11 to lift the lifting frame 2, ensuring the support height of the telescopic bracket 3 is higher than the installation position of the arch steel plate. Then, based on the curvature of the arch steel plate to be lifted, pre-adjust the overall lifting angle of the telescopic bracket 3 using the hydraulic telescopic column A5. Afterward, adjust the support position of the movable frame 32 using the hydraulic telescopic column B33. Figure 5 As shown, the positions of the two lifting rollers 34 are adjusted to appropriate positions. Then, an external overhead crane is used to place the arched steel plate between the two lifting rollers 34. During placement, the servo motor A7 can be used to drive the lifting roller 34 on one side to rotate. Since the lower surface of the arched steel plate is in contact with the lifting roller 34, the rotating lifting roller 34 can be used to move the arched steel plate to the left or right to adjust its placement position, so that it is symmetrically lifted on both sides between the two lifting rollers 34. This ensures that the middle section of the arched steel plate is located within the clamping mechanism 6, reducing the damage to the clamping mechanism 6 when the arched steel plate is misaligned. Finally, the clamping mechanism 6 is used to clamp and fix the arched steel plate placed between the two lifting rollers 34. Then, the hydraulic telescopic column C11 is retracted to move the lifting frame 2 down, moving the arched steel plate to a suitable installation position. Compared with the prior art, this device can easily adapt and adjust the support position according to the arched steel plate with different curvatures during actual use, making it more adaptable.
