[0029] Example 1:

[0030] A shield tunneling excavator hopper hoisting device includes a gantry crane trolley 1, a movable pulley 2, a connecting beam 3, and a gantry crane main hook beam 4. The gantry crane trolley 1 is located at the top, and the movable pulley 2 is located between the gantry crane trolley 1 and the gantry crane main hook beam 4. The movable pulley 2 is connected to the gantry crane trolley 1 by a cable to realize the up and down lifting of the movable pulley 2. One end of the connecting beam 3 is rotatably connected to the movable pulley 2, while the other end of the connecting beam 3 is fixedly connected to the gantry crane main hook beam 4. A plate hook 5 is rotatably connected to the connecting beam 3, and the connecting beam 3 can be hinged to the plate hook 5 for rotatable connection. A hoisting hole 6 is opened on the plate hook 5, and the hoisting hole 6 cooperates with the lifting lug 8 installed on the excavator hopper 7. A rotation drive assembly is connected to the side of the plate hook 5, which can pull the plate hook 5, thereby driving the plate hook 5 to rotate along the connecting beam 3, so that the hoisting hole 6 enters or exits the lifting lug 8.

[0031] In use, first hoist the plate hook 5 to the appropriate position. When it is necessary to hoist the muck box 7, activate the rotation drive assembly to rotate the plate hook 5, allowing the lifting lug 8 to pass through the hoisting hole 6, and then start the hoisting. When it is necessary to lower the muck box 7, activate the rotation drive assembly again to rotate the plate hook 5, disengaging the hoisting hole 6 from the lifting lug 8. The entire process requires no manual labor, and no personnel need to be present on-site in the construction area, reducing installation risks.

[0032] Furthermore, the lifting hole 6 is an elongated through hole with one end larger than the other, and the diameter of the hole at the end closer to the connecting beam 3 is larger than the diameter of the hole at the other end. The lifting lug 8 on the slag box 7 is a cylindrical rod structure, and the lifting lug 8 is adapted to the larger end of the lifting hole 6. The advantage of this design is that it provides a certain buffer space for the lifting hole 6 to be smoothly hung on the lifting lug 8.

[0033] Furthermore, the rotation drive assembly includes a telescopic component 9, a lifting rope 10, and a guide pulley 11. The telescopic component 9 can be an electric telescopic rod, which is installed on the main hook beam 4 of the gantry crane. One end of the lifting rope 10 is fixedly connected to the telescopic end of the telescopic component 9, and the other end is connected to the plate hook 5 through the guide pulley 11. Mounting bases 12 can be fixedly installed on both ends of the main hook beam 4 of the gantry crane, and then the electric telescopic rod is installed on the main hook beam 4 of the gantry crane through the mounting bases 12. The guide pulley 11 is installed at the end of the mounting base 12. The mounting base 12 can be made of steel plate.

[0034] Even better, a proximity switch 13 is provided on the mounting base 12, with the proximity switch 13 located between the telescopic member 9 and the guide pulley 11, and two proximity switches 13 are spaced apart. The purpose of providing the proximity switch 13 is to limit the telescopic length of the electric telescopic rod.

[0035] Each of the two mounting bases 12 is also equipped with a camera 14 to film the hoisting process of the dump box 7. The operator adjusts the operation based on the filmed images.

[0036] A laser rangefinder 15, model SW-LDS50B, is also installed on the gantry crane trolley 1, with a measuring distance of 0.05m-50m. A laser rangefinder enhancement reflector 16 is installed on the main hook beam 4 of the gantry crane, and the position of the laser rangefinder 16 is matched with the position of the laser rangefinder 15. The laser rangefinder 15 can measure the distance between the gantry crane trolley 1 and the main hook beam 4 of the gantry crane, thereby determining the height of the hook 5.

[0037] A spring-loaded cable reel 17 is installed on the main hook beam 4 of the gantry crane. The cable reel 17 is connected to the gantry crane trolley 1 via a tensile cable 19, thereby supplying power to the main hook beam 4 of the gantry crane to power the electric telescopic boom and the camera 14.

[0038] In this embodiment, a positioning stop bar 18 is also provided on the slag box 7. The positioning stop bar 18 is located on the side of the lifting lug 8 to position the plate hook 5.

[0039] The process of using the hoisting device of this utility model is as follows:

[0040] First, install the device:

[0041] (1) Two 2000mm long No. 10 I-beams are used as the mounting base 12 for this system device, according to... Figure 1 As shown, the electric telescopic rod, guide pulley 11, proximity switch 13, etc. are installed on the mounting base 12, and two sets are assembled.

[0042] (2) Using the original gantry crane main hook beam 4, weld and fix the two sets of devices assembled in (1) to their ends respectively. The welding position should be centered at the end and flush at the top.

[0043] (3) Adjust and install the lifting rope 10 according to the angle that needs to be adjusted according to the plate hook 5.

[0044] (4) Using the main hook beam 4 of the gantry crane, a spring-loaded cable reel 17 is installed on its left side. One end of the tensile cable 19 on the reel is fixed to the gantry crane trolley 1 to provide power to the entire system. A laser rangefinder reflector 16 is installed on the right side of the main hook beam 4 of the gantry crane, and a laser rangefinder 15 is installed in the corresponding position inside the gantry crane trolley 1.

[0045] (5) Weld a horizontal positioning stop bar on the side of the slag box 7.

[0046] II. Commissioning and Operation of the Hoisting Device for Excavated Soil Box 7 during Shield Tunneling Construction:

[0047] (1) Hook

[0048] The shield tunneling battery vehicle transports the muck box 7 to the hoisting wellhead, and the gantry crane main hook is lowered. The gantry crane main hook stops when it reaches the set height (the hoisting lug 8 of the muck box 7 is aligned with the upper part of the hoisting hole 6 of the plate hook 5, and the height can be obtained by the laser rangefinder 15).

[0049] Start the electric telescopic rod to open the hooks 5 outwards; gantry crane trolley, so that the inner sides of the two hooks 5 are basically aligned with the two ends of the slag box 7; operate gantry crane trolley 1 to move the two hooks 5 toward the horizontal positioning stop bar welded on the slag box 7; continue to operate the electric telescopic rod to close the hooks 5 inwards.

[0050] The main hook beam 4 of the gantry crane is slowly lifted upwards, and the lifting lug 8 of the slag box 7 slides to the bottom of the lifting hole 6 of the plate hook 5, thus completing the automatic hooking operation.

[0051] (2) Unhooking

[0052] Operate the gantry crane trolley and trolley to position the slag container 7 above the hoisting wellhead, and lower the gantry crane main hook beam 4 to place the slag container 7 onto the chassis of the shield tunneling battery vehicle slag container 7.

[0053] Continue lowering the gantry crane main hook beam 4 to the set height (when the slag box 7 lifting lug 8 is aligned with the upper part of the plate hook 5 lifting hole 6, and the height can be obtained by the laser rangefinder 15).

[0054] Operate the electric telescopic rod to open the hook 5 outward; operate the gantry crane trolley 1 to remove the hook 5 from both sides of the slag box 7; continue to operate the electric telescopic rod to close the hook 5 inward, thus completing the unhooking operation.

[0055] By repeating this process, the automatic hooking and unhooking of the excavation boxes during tunnel boring machine (TBM) construction can be achieved. This device reduces the need for personnel to participate in construction, significantly lowering project construction costs and safety hazards.
