Description

Technical Field

[0001] This application relates to the field of tunneling machine technology, and more particularly to a rotating center structure for a vertical shaft tunneling machine. Background Technology

[0002] In the main structure, or main chamber, of a shaft boring machine, one of the main movements during tunneling is rotation, mostly within ±190 degrees. ° The digging operation is driven by a rotary drive located within the main chamber, which in turn powers the actuators at the bottom of the main chamber. The cables, hydraulic lines, grease lines, and mud lines of the actuators at the bottom of the main chamber must pass through the main chamber; that is, the cables and hydraulic lines passing through the main chamber must be flexible enough to accommodate the rotary motion. The mechanism that enables the rotary motion of the cables, hydraulic lines, and mud lines is also called a rotary center structure.

[0003] However, in the existing rotating center structure of shaft boring machines, the mud channel, hydraulic channel, grease channel and cable rotating slip ring are integrated into a single rotating mechanism, which is relatively complex and requires high sealing performance, resulting in high operating costs.

[0004] Therefore, how to provide a rotating center structure for a shaft tunneling machine that can reduce the use and maintenance costs of the rotating center structure through mechanical structural improvements and innovations has become a technical goal that urgently needs to be achieved by those skilled in the art.

[0035] Specifically, in an embodiment of the present invention, the rotating body 3 further includes a bearing 33, and the outer rotating frame 31 and the inner rotating frame 35 are connected by the bearing 33.

[0036] Specifically, in an embodiment of the present invention, it further includes an inner sealing structure 34 disposed between the outer rotating frame 31 and the inner rotating frame 35.

[0037] Specifically, in embodiments of the present invention, it further includes: an external sealing structure 32 for protecting the bearing 33, preventing mud and water passing through the mud channel from entering the bearing mounting cavity.

[0038] Specifically, in an embodiment of the present invention, the functional pipeline harness includes: mud pipe 5, hydraulic pipe 7, and grease pipe 8.

[0039] Specifically, in an embodiment of the present invention, the functional wiring harness further includes a cable 6, which passes through the rotating frame 9 and is concentrated in the outer cavity of the rotating frame 9 before reaching the main body 1.

Furthermore, the mud pipe 5 enters the outer cavity from the upper end face of the rotating frame 9; or the mud pipe 5 enters the outer cavity of the rotating frame 9 from the side door structure.

[0041] More specifically, the number of side door structures is two or more, and the two or more side door structures are used to insert different types of the functional wiring harnesses.

[0042] To elaborate more specifically, the following, in conjunction with the accompanying drawings and the specific application background and environment of this solution, further elaborates on the technical details of the embodiments of the present invention. The present utility model provides a rotating center structure for a vertical shaft tunneling machine that is a drag chain moving type. The drag chain moving type utilizes the drag chain to achieve rotational motion while also planning the cables, hydraulic pipes, grease pipes and mud pipes, resulting in relatively low cost.

[0043] The present invention relates to the following solutions: a main body 1; an adjusting block 2; and a rotating body 3, wherein the rotating body 3 includes: an outer rotating frame 31; an outer sealing structure 32; a bearing 33; an inner sealing structure 34; an inner rotating frame 35; a drag chain structure 4; a mud pipe 5; a cable 6; a hydraulic pipe 7; a grease pipe 8; a rotating frame 9; and a mud outlet channel 10.

[0044] Among them, the slewing frame 9 rotates relative to the main body 1. The slewing frame 9 and the main body 1 are sealed together. The adjusting block 2 and the outer frame 31 of the slewing body 3 are fixed to the main body 1. The inner frame 35 of the slewing body 3 is fixedly connected to the slewing frame 9 and follows its rotation.

[0045] Mud pipe 5, cable 6, hydraulic pipe 7, and grease pipe 8 pass through the rotating frame 9 and reach the actuator below the main body 1 after passing through the centralized pipe bundle in the outer cavity of the rotating frame 9. They move with the rotational motion via the drag chain structure 4. The slurry pump of the actuator below the main shaft needs to pump the mud to the ground. The mud can be discharged through the mud outlet channel 10 passing through the main body of the shaft.

[0046] In the solution of this utility model embodiment, the cable 6, hydraulic pipe 7, grease pipe 8, and mud pipe 5 are planned by the drag chain 4. The fixed end of the drag chain structure 4 is fixed to the main body 1, and the other end is fixed to the rotating frame 9, so that the drag chain structure 4 rotates and moves with the rotation of the rotating frame 9. The cable 6, hydraulic pipe 7, grease pipe 8, and mud pipe 5 pass through the rotating frame 9 and reach the actuator under the main body of the main body.

[0047] Among them, the outer rotating frame, the adjusting block 2 and the main body 1 are fixed, and the inner rotating frame is fixedly connected to the rotating frame. Since the rotating frame rotates relative to the main body 1, the outer rotating frame and the inner rotating frame rotate relative to each other, and the two are connected by bearings.

[0048] The mud outlet channel 10 passes through the central cavity of the rotating frame 9, the central cavity of the rotating body, the central cavity of the adjusting block 2 and the central cavity of the main body 1. Since the inner and outer frames of the rotating body 3 move relative to each other, an external sealing structure 32 is provided to protect the bearing and prevent the mud and water passing through the mud outlet channel from entering the bearing mounting cavity.

[0049] It should be noted that the solutions involved in the embodiments of this utility model include the following key technologies:

[0050] Cable 6, hydraulic pipe 7, grease pipe 8, and mud pipe pass through drag chain structure 4, then through rotating frame 9, and are pulled out from the cavity of rotating frame 9. Mud pipe 5 can be inserted through the upper end face of the cavity of rotating frame 9, and other pipelines can be inserted through the side opening of rotating frame. One end of drag chain structure 4 is fixed to main body 1, and the other end is fixed to rotating frame 9. The rotation of rotating frame 9 causes drag chain structure 4 to move. Mud outlet channel 10 is the central cavity of rotating frame, rotating body, adjusting block, and main body. The inner frame of rotating body is fixedly connected to rotating frame, and the outer frame of rotating body is connected to main body, realizing the relative rotational movement of inner and outer frames of rotating body.

[0051] Furthermore, it should be noted that the method of inserting pipelines into the rotating frame 9 in this technical solution is only one embodiment and not the only embodiment. The upper end of the outer cavity of the rotating frame 9 can be moved further up, and the side door can be raised so that mud pipes, cables, hydraulic pipes, and grease pipes can be inserted through the side door.

[0052] In summary, in the solution of this utility model embodiment, all cables, pipes, etc. pass through the rotating frame and are bundled together in the outer cavity of the rotating frame before reaching the actuator, which facilitates centralized management of pipelines and results in a compact structure. Furthermore, due to the large diameter of the mud outlet channel, the central cavity of the rotating frame and the central cavity of the rotating body are utilized, eliminating the need for cable chains as with cables, hydraulic pipes, and grease pipes, thus simplifying the structure. In addition, the setting of the adjusting block provides a certain amount of length deformation to accommodate the error adjustment caused during production and installation.

[0053] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
