Figure 1 , 3As shown in Figure 5, by sleeve-connecting the buffer spring 9 on the outer side of the adjusting rod 10, it is convenient to control the descent of the sliding block 8 while the adjusting rod 10 is stably connected to the sliding block 8, and it is also convenient to provide power for resetting the adjusting rod 10, which makes the use of the adjusting rod 10 more convenient and quick, and also reduces the production cost of the hydraulic gantry crane, thereby making the hydraulic gantry crane more practical.

[0033] Among them, the bottom of the adjusting rod 10 is slidably connected with an inclined block 11, and one side of the inclined block 11 is fixedly connected with an extrusion spring 12, and one side of the extrusion spring 12 is fixedly connected with a sliding frame 13, and the outer side of the sliding frame 13 is slidably connected with a sliding groove 14, and one end of the sliding frame 13 is fixedly connected with a torsion spring 15, and one side of the torsion spring 15 is fixedly connected with a clamping plate 16; the extrusion spring 12 is fixedly connected to one side of the inclined block 11 close to the clamping plate 16; the clamping plates 16 are symmetrically arranged on both sides of the sliding frame 13, and the clamping plates 16 are rotatably connected to both sides of the sliding frame 13, and the inner side of the clamping plate 16 is rotatably connected with a ball, such as Figure 1 , 2 As shown in Figures 3, 4 and 6, by providing a symmetrical clamping plate 16, it is convenient to clamp the tank container in the center so that the tank container falls directly under the lifting block 5, thereby reducing the situation where the tank container shakes significantly during lifting.
