The clamping mechanism 2 can clamp and fix the door frame / door body, and can complete the repositioning operation of the door frame or door body from a horizontal position to a vertical position or from a vertical position to a horizontal position.

[0033] Specifically, such as Figure 1 As shown, the base 1 includes a base plate 1-1, a rotating shaft 1-2, and two supports 1-3. The two supports 1-3 are parallel to each other (the supports 1-3 are plate-like structures that are narrower at the top and wider at the bottom), and are welded and fixedly mounted on the base plate 1-1. Corresponding through holes are formed on the two supports 1-3. The rotating shaft 1-2 passes through the two through holes and is rotatably connected to the two supports 1-3 via bearings. The clamping mechanism 2 is mounted on the rotating shaft 1-2 and is rotatably connected to the supports 1-3 via the rotating shaft 1-2.

[0034] The clamping mechanism 2 includes two identical support plates 2-1 and two clamping plates 2-2. The two support plates 2-1 are parallel to each other (the support plates 2-1 are plate-like structures that are wider at the top and narrower at the bottom), and the two clamping plates 2-2 are parallel to each other. The two clamping plates 2-2 are respectively disposed on both sides of the support plates 2-1, and the clamping plates 2-2 are welded and fixed to both support plates 2-1. The two support plates 2-1 are provided with corresponding through holes, and the support plates 2-1 are sleeved on the rotating shaft 1-2 through the through holes and fixedly connected to the rotating shaft 1-2. The support plates 2-1 can rotate relative to the support 1-3. The door frame / door body is fixed between the two clamping plates 2-2 by fasteners.

[0035] The distance between the two clamping plates 2-2 is less than the distance between the two supports 1-3, and the two clamping plates 2-2 are distributed inside the two supports 1-3. The support plate 2-1 is provided with a mounting groove that matches the shape of the door frame / door body, and a buffer pad is provided in the mounting groove. A buffer pad (rubber pad) is provided inside the clamping plate 2-2, which can protect the thin plate at the bottom edge of the door frame and the sealing strip at the bottom of the door body.

[0036] In this embodiment, a door frame / door body moving part 11 is also provided. The door frame / door body moving part 11 is located on one side of the base 1 and is used to support the door frame or door body. The door frame / door body moving part 11 is slidably or rollingly connected to the ground. The door frame / door body moving part 11 is a telescopic structure and its height is adjustable, so that the door frame / door body can correspond to the mounting slot of the clamping mechanism 2.

[0037] In this embodiment, a positioning pin 8 is also provided, such as Figure 1 As shown, the support 1-3 has several pin holes 9, and correspondingly, the support plate 2-1 has at least one positioning hole 10. The positioning pin 8 can be inserted into the corresponding pin hole 9 and positioning hole 10 at the same time to achieve relative fixation of the base 1 and the clamping mechanism 2.

[0038] Application process of this device:

[0039] Rotate the clamping mechanism 2 relative to the base 1 so that the mounting slot of the clamping mechanism 2 is in a horizontal state;

[0040] Insert the positioning pin 8 into the corresponding pin hole 9 and positioning hole 10 at the same time to keep the clamping mechanism 2 fixed in a horizontal state;

[0041] The door frame / door body is horizontally moved to the clamping mechanism 2 by the door frame / door body moving part 11. The height of the door frame / door body moving part 11 is adjusted so that the door frame / door body corresponds to the position of the mounting groove. The door frame / door body is horizontally moved so that one end of it moves into the mounting groove.

[0042] The door frame / door body is fixed to the clamping mechanism 2 by fasteners, and the hoisting mechanism is connected to the top of the door frame / door body;

[0043] Remove the positioning pin 8 from the pin hole 9 and the positioning hole 10;

[0044] Start the hoisting mechanism to hoist the door frame / door body to a vertical position (the clamping mechanism 2 can rotate accordingly), and insert the positioning pin 8 back into the corresponding pin hole 9 and positioning hole 10 to keep the clamping mechanism 2 fixed in a vertical position.

[0045] Remove the fasteners to separate the door frame / door body from the clamping mechanism 2, complete the hoisting and repositioning operation of the long strip door frame and door body, and proceed with subsequent installation procedures.

[0046] Example 2

After the long, narrow door frame is moved into the mounting groove, the screw 3 is passed through the two clamping plates 2-2 and the through hole of the long, narrow door frame, and then two nuts 4 are screwed onto both sides of the screw 3 to secure it, thus achieving a fixed connection between the long, narrow door frame and the clamping mechanism 2. The hoisting and repositioning process of the long, narrow door frame is as follows: Figure 7 As shown.

[0050] Example 3

[0051] This embodiment has the same main structure as Embodiment 2, the difference being that this embodiment provides another structure for the fastener.

[0052] Specifically, refer to Figures 3-4 The two clamping plates 2-2 are provided with corresponding threaded holes. The fixing component includes two bolts 6 and two clamping plates 7. The two bolts 6 are respectively threaded into the threaded holes of the two clamping plates 2-2, and the clamping plates 7 are installed inside the bolts 6, with the two clamping plates 7 distributed between the two clamping plates 2-2. A buffer pad is provided on the inner side of the clamping plate 7.

[0053] This embodiment is applicable to the hoisting and repositioning of long, narrow door panels, eliminating the need for drilling holes in the door panel. After the long, narrow door panel is moved into the mounting slot, the two bolts 6 are tightened to move the two clamping plates 7 toward the long, narrow door panel until the two clamping plates 7 clamp and fix the long, narrow door panel, thus achieving a fixed connection between the long, narrow door panel and the clamping mechanism 2. The hoisting and repositioning process of the long, narrow door panel is as follows: Figure 8 As shown.

[0054] This invention solves the problems of long preparation time, easy deformation of thin door frame plates, and damage to sealing strips in the installation of stainless steel water tank gates in nuclear power plants. It can quickly and conveniently realize the hoisting and repositioning operation of long door frames or doors during installation, simplifying the construction process, reducing manpower input, and conveniently, reliably, and efficiently repositioning the door frame or door from a horizontal position to a vertical position. It ensures that the weak points of the door frame or door are not damaged, saves labor, is easy to operate, has high reliability, and good stability.
