Description

Technical Field

[0001] This utility model belongs to the field of tunnel segment hoisting technology, specifically, it relates to a rotating hoisting tool for hoisting tunnel segments of a shield machine. Background Technology

[0002] In underground engineering construction, shield tunneling is widely used due to its advantages such as high efficiency, safety, and environmental friendliness, especially in projects such as subway tunnels, urban underground utility tunnels, and railway tunnels. The core of shield tunneling lies in the efficient advancement of the tunnel boring machine (TBM) and the rapid assembly of tunnel segments. As the main structural material for tunnel lining, the efficiency and quality of the hoisting and assembly of tunnel segments directly affect the progress of the shield tunneling project and the safety of the tunnel. Traditional methods of tunnel segment hoisting mainly rely on gantry cranes or the hoisting equipment built into the TBM itself.

[0003] The segment crane is an integral part of the tunnel boring machine (TBM) segment transportation process. As a crane spanning the TBM connecting bridge and multiple trailers, it is responsible for transporting most of the materials inside the TBM, including segments and grease drums. First, the segment transport vehicle moves the segments from outside the tunnel to the segment unloading machine below the trailer. Then, the segment crane lifts the segments from the unloading machine onto a segment trolley below the first trailer. Finally, the segment trolley transports the segments to the segment assembly machine for assembly. However, existing segment cranes have fixed lifting devices, and the limited space within the tunnel restricts multi-directional movement of the segments, resulting in low lifting efficiency. Therefore, a simple, easy-to-operate rotating lifting device for TBM segment lifting that allows for multi-directional segment movement is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a rotating lifting device for tunnel boring machine segments that is simple in structure, easy to operate, and can realize multi-directional movement of tunnel segments. The device drives the mechanical grippers to rotate through a power component, thereby driving the tunnel segments to rotate. With the help of corresponding lifting equipment, it can realize multi-directional movement of tunnel segments, greatly improving the lifting efficiency of tunnel segments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotating lifting device for tunnel boring machine segment hoisting includes a pulley box, a pulley block, a pulley mounting shaft, a left force plate, a right force plate, a mounting block, a vertical rotating shaft, a power assembly, and mechanical grippers. The pulley mounting shaft and the pulley block are both installed inside the pulley box. The pulley mounting shaft is installed laterally inside the pulley box, and the pulley block is installed on the pulley mounting shaft. The left and right force plates are symmetrically arranged and connected to the pulley box at the top. The mounting block is connected to the mounting block at the bottom of the left and right force plates. The mounting block is installed on the vertical rotating shaft through a first bearing. The power assembly is driven and connected to the vertical rotating shaft. The mechanical grippers are installed at the bottom end of the vertical rotating shaft through a mounting bracket.

[0007] The power assembly includes a rotary motor, a drive gear, and a driven gear. The drive gear is mounted on the output shaft of the rotary motor, and the driven gear meshes with the drive gear. The driven gear is mounted on a vertical rotating shaft.

[0008] The vertical rotating shaft includes an upper threaded section, an intermediate rotating section, and a lower threaded section. An upper hook nut is installed on the upper threaded section, and a lower hook nut is installed on the lower threaded section. A second bearing is installed between the lower end of the upper hook nut and the upper end of the mounting block. The mechanical gripper is installed on the lower hook nut via corresponding screws.

[0009] The lower end of the mounting block is connected to a gear cover by corresponding screws. Both the driving gear and the driven gear are set inside the gear cover, and the rotary motor is mounted on the gear cover.

[0010] The pulley box is equipped with a left partition and a right partition, which are connected to the left force plate and the right force plate, respectively. The left partition, the right partition, the left force plate and the right force plate are all provided with through holes corresponding to the pulley mounting shaft.

[0011] The pulley system includes a left pulley group and a right pulley group. Each pulley group includes two pulleys. A left partition is set between the two pulleys of the left pulley group, and a right partition is set between the two pulleys of the right pulley group. Each pulley is mounted on the pulley mounting shaft through two self-aligning bearings, and a spacer ring is provided between the two self-aligning bearings.

[0012] The rotating hoist of this application drives the vertical rotating shaft to rotate via a power component, which in turn drives the mechanical gripper installed at the bottom of the vertical rotating shaft to rotate. This enables the mechanical gripper to rotate, thus facilitating the clamping of the tunnel segments by the mechanical gripper. This makes the tunnel segment hoist of this application easy to operate and highly adaptable. Attached Figure Description

The mounting block 14 is mounted on the vertical rotating shaft 15 through the first bearing 54. The power assembly 16 is connected to the vertical rotating shaft 15 for transmission. The mechanical gripper 17 is mounted on the bottom end of the vertical rotating shaft 15 through the mounting bracket 65. The mounting bracket 65 is equipped with a corresponding control device for controlling the clamping and loosening of the mechanical gripper 17. The mechanical gripper 17, the mounting bracket 65 and the corresponding control device are all existing structures and will not be described in detail here.

[0018] The power assembly 16 includes a rotary motor 49, a drive gear 50, and a driven gear 51. The drive gear 50 is mounted on the output shaft of the rotary motor 49, and the driven gear 51 meshes with the drive gear 50. The driven gear 51 is mounted on the vertical rotation shaft 15.

[0019] The vertical rotating shaft 15 includes an upper threaded section, an intermediate rotating section, and a lower threaded section. An upper hook nut 52 is installed on the upper threaded section, and a lower hook nut 53 is installed on the lower threaded section. A second bearing 55 is installed between the lower end of the upper hook nut 52 and the upper end of the mounting block 14. The second bearing 55 is a thrust roller bearing.

Then, the control device in the mounting bracket 65 controls the mechanical gripper 17 to insert into the corresponding groove of the segment 63 and clamp the connecting bridge segment 63. During the clamping process of the segment 63, the rotary motor 49 drives the drive gear 50 to rotate, which in turn drives the driven gear 51 to rotate, thereby driving the vertical rotation shaft 15 to rotate.
