The positioning and installation assembly 5 comprises a fixed support 6 fixedly connected with the modular frame 4, and a linkage hook plate 7 installed on the fixed support 6, and the linkage hook plate 7 is provided with a hook-shaped supporting plate below, so as to be fixedly supported on the plate surface structure of the gate 2 through the hook-shaped supporting plate, Figure 1 The plate surface of the gate 2 shown in the figure is provided with a grid type reinforcing rib structure, and the hook-shaped supporting plate is hooked on one of the transverse reinforcing rib structures, so as to be lifted by the other positioning parts.

[0035] The fixed support 6 is fixedly installed on the modular frame 4, for example, by bolts, and the linkage hook plate 7 is connected with the upper and lower positions of the fixed support 6, the lower end of the fixed support 6 is hinged with the linkage hook plate 7 through a pin shaft, and the upper end of the fixed support 6 is also connected with the linkage hook plate through a position adjusting structure, so that the linkage hook plate 7 can rotate within a certain range of amplitude around the pin shaft at the lower end of the fixed support 6, so as to adjust the lifting angle of the linkage hook plate 7. Referring to Figure 4The linkage hook plate 7 is also provided with a first adsorption adjustment component 12 and a second adsorption adjustment component 13. The first adsorption adjustment component 12 and the second adsorption adjustment component 13 have the same structure and are installed in an upper and lower position along the linkage hook plate 7.

[0036] like Figure 5 As shown in the figure, the first adsorption adjustment component 12 is disassembled to describe its structural composition in detail. The first adsorption adjustment component 12 includes a switch-type permanent magnet 15, a mounting flange 16, a support arm 17, a threaded rod 18 and a cross pin 20. The cross pin 20 is a structure in which an additional part with a threaded hole is provided in the middle of the pin rod. The axial direction of the threaded hole of the additional part is perpendicular to the axial direction of the pin rod. The cross pin 20 is hingedly mounted on the linkage hook plate 7 through its pin rod. The support arm 17 is a strip-shaped load-bearing arm structure. A strip-shaped cavity is formed inside the support arm 17 that passes through both sides and extends along its axial direction. In the assembled state, the cross pin 20 is located in the strip cavity. The pin rods of the cross pin 20 extend from both sides of the strip cavity to be hinged with the linkage hook plate 7. The additional part of the cross pin 20 is accommodated in the strip cavity; the strip of the support arm 17 The shaped cavity also accommodates a threaded rod 18, which includes a thick-diameter threaded section accommodated in the strip-shaped cavity and a thin-diameter positioning rod and an operating rod respectively located at both ends of the threaded section; the threaded section of the threaded rod 18 is threadedly fitted through the threaded hole of the attachment, and the positioning rods and operating rods at both ends of the threaded rod 18 also axially pass through the axial sides of the support arm 17 respectively. Specifically, the outer end of the support arm 17 is fixedly installed with a mounting flange 16, and the mounting flange 16 is provided with a rotating support for accommodating the positioning rod at the end of the threaded rod 18 on the side facing the support arm 17, so that the positioning rod is rotatably supported in the blind hole of the rotating support, and the inner end of the support arm 17 forms a through hole for the operating rod of the threaded rod 18 to pass through, and the aperture of the through hole is adapted to the diameter of the operating rod, so that the threaded section of the threaded rod 18 can be clamped in the strip-shaped cavity of the support arm 17. A hand lever 19 may be provided at the end of the operating rod of the threaded rod 18. The hand lever 19 is used to rotate the threaded rod 18. Since the cross pin 20 is hinged to the linkage hook plate 7 and the relative position is fixed, when the threaded rod 18 rotates inside the threaded hole of the cross pin 20, the threaded rod 18 moves forward and backward along the axial direction relative to the threaded hole, thereby driving the support arm 17 to move forward and backward relative to the linkage hook plate 7. A switch-type permanent magnet 15 is fixedly mounted on the side of the mounting flange 16 facing away from the support arm 17. The switch-type permanent magnet 15 is used to be magnetically adsorbed on the plate surface of the gate 2 after the switch is turned on. To facilitate construction, when the gate 2 is not a monolithic metal structure, multiple steel adsorption plates can be fixedly laid on the plate surface of the gate 2 with bolts to cooperate with the switch-type permanent magnet.

[0037] The second adsorption adjustment component 13 has the same structure as the first adsorption adjustment component 12 and is also installed with the linkage hook plate 7 through a cross pin 20. For details, see Figure 8 , is a schematic diagram of the linkage hook plate structure of the positioning and mounting assembly in the present invention, the bottom of the linkage hook plate 7 is laterally bent to form a hook-shaped support plate 14, and a radial first pin hole 8, a second pin hole 9, a third pin hole 10 and a fourth pin hole 11 are sequentially provided on the main body of the linkage hook plate 7 from top to bottom. The first pin hole 8 and the third pin hole 10 are respectively used for hingedly mounting a cross pin shaft 20 for mounting the first adsorption adjustment assembly 12 and the second adsorption adjustment assembly 13, the fourth pin hole 11 is hingedly connected to the lower part of the fixed support 6, and the second pin hole 9 is used for hingedly mounting the position adjustment structure of the upper end of the fixed support 6.

The limit pin 21 includes a pin rod and a threaded hole in the middle of the pin rod, which is hinged to the second pin hole 9 on the linkage hook plate 7 through the pin rod. Preferably, when the limit pin 21 is hingedly installed in the second pin hole 9, it can only rotate around its pin rod and cannot rock left and right; the threaded adjustment rod 22 is threadedly fitted into the threaded hole of the limit pin 21, and the rear end of the threaded adjustment rod 22 and the rear end seat 23 of the threaded adjustment rod can rotate relative to each other but not axially. The movable clamping connection is that the rear end seat 23 of the threaded adjustment rod is hingedly mounted on the upper end of the fixed support 6, so that when the threaded adjustment rod 22 is rotated, the threaded hole of the limit pin 21 cooperates with the threaded adjustment rod 22 to cause it to move axially along the threaded adjustment rod 22, thereby driving the linkage hook plate 7 to move closer to or away from the fixed support 6. The fourth pin hole 11 at the lower position of the linkage hook plate 7 is hingedly mounted on the lower end of the fixed support 6. When the linkage hook plate 7 moves closer to or away from the fixed support 6, the linkage hook plate 7 as a whole rotates around the pin in its fourth pin hole 11, so that the angle of the hook-shaped support plate 14 at the lower end of the linkage hook plate 7 can be adjusted. To facilitate the rotation of the threaded adjustment rod 22, a hand lever 19 can also be installed at the end of the threaded adjustment rod 22.
