The combined box of the first trapezoidal hollow steel wedge 1 and the second trapezoidal hollow steel wedge 10 is called a drop block.

[0021] Two symmetrically distributed clamping rings 2 are provided on the outside of the through rod 15, wherein two symmetrically distributed first fixing blocks 21 are fixedly installed on the outside of one of the clamping rings 2, and two symmetrically distributed second fixing blocks 22 corresponding to the first fixing blocks 21 are fixedly installed on the outside of the other clamping ring 2, and a same guide rod 23 is slidably penetrated through the middle of the first fixing block 21 and the second fixing block 22 located above, and two symmetrically distributed fixing seats 24 are fixedly installed on the outside of the guide rod 23, and a first fixing plate 25 is fixedly installed on the side of the fixing seat 24 close to the first trapezoidal hollow steel wedge block 1, and a second fixing plate 26 is fixedly installed on the top of the first fixing plate 25, and a placement groove 27 is opened inside the second fixing plate 26, and a threaded rod 28 is threadedly connected to the middle of the second fixing block 22 located below, and the threaded rod 28 is threadedly connected to the corresponding first fixing block 21.

[0022] By adopting the above technical solution, when the threaded rod 28 is rotated, the threaded rod 28 is inserted into the corresponding first fixed block 21, and the clamp ring 2 is fixed on the through rod 15. At the same time, the second fixed plate 26 clamped on the first trapezoidal hollow steel wedge block 1 and the first fixed plate 25 fitted with the first trapezoidal hollow steel wedge block 1 are fixed, and then the second trapezoidal hollow steel wedge block 10 is directly placed in the placement groove 27, so that the inclined surface of the second trapezoidal hollow steel wedge block 10 is more accurately fitted with the inclined surface of the first trapezoidal hollow steel wedge block 1, which is convenient for the installation of the second trapezoidal hollow steel wedge block 10.

[0023] The first trapezoidal hollow steel wedge 1 and the second trapezoidal hollow steel wedge 10 are both provided with a second slot 16 through the inclined surface, and the finishing screw 12 is movable through the second slot 16 .

[0024] By adopting the above technical solution, the installation of the finishing screw 12 is facilitated.

[0030] By adopting the above technical solution, the installation of the second trapezoidal hollow steel wedge 10 and the installation of the finishing screw 12 are facilitated.

[0031] Working principle: In actual use, firstly, a part of the bottom of the placement groove 27 in the second fixing plate 26 is clamped on the first trapezoidal hollow steel wedge 1, and at the same time, the first fixing plate 25 and the first trapezoidal hollow steel wedge 1 are fitted together, and then the through-rod 15 is passed through the two clamping rings 2 and the circular hole 14 on the first trapezoidal hollow steel wedge 1, and then the two clamping rings 2 are moved toward the middle. While moving, the first fixing block 21 and the second fixing block 22 located above slide toward the middle on the guide rod 23, and the first fixing block 21 and the second fixing block 22 located below also move toward the middle, so that the two first fixing blocks 21 and the second fixing blocks 22 fit together, and then the rotating wheel 29 is rotated to drive the threaded rod 28 to rotate, so that the threaded rod 28 is clamped into the corresponding first fixing block 21, so that the clamping ring 2 is fixed on the through-rod 15, and at the same time, the first fixing plate 25 and the second fixing plate 26 are fixed;

[0032] After being fixed, the second trapezoidal hollow steel wedge 10 is directly placed in the placement groove 27, and then the inclined surface of the second trapezoidal hollow steel wedge 10 is directly fitted with the inclined surface of the first trapezoidal hollow steel wedge 1, and then the side of the finishing screw 12 where the high-strength bolts 13 and the gasket 17 are not installed passes through the first trapezoidal hollow steel wedge 1 and the first empty groove 11 and the second empty groove 16 on the second trapezoidal hollow steel wedge 10, and then the high-strength bolts 13 and the gasket 17 are installed on the side of the finishing screw 12 where the high-strength bolts 13 and the gasket 17 are not installed. The gasket 17 is then rotated and the high-strength bolts 13 on both sides are moved toward the middle, so that the corresponding first trapezoidal hollow steel wedge 1 and the second trapezoidal hollow steel wedge 10 of the gasket 17 are fitted together, thereby completing the installation of the unloading block. After the installation is completed, the rotating wheel 29 is directly rotated in the opposite direction to drive the threaded rod 28 to rotate in the opposite direction, so that the threaded rod 28 is disengaged from the corresponding first fixed block 21, and then the first fixed plate 25, the second fixed plate 26 and the clamping ring 2 are removed, and finally the through rod 15 and the unloading block are installed on the pier.
