Technical Field

[0001] This utility model relates to the field of shield tail brush assembly technology, and in particular to a shield tail brush assembly and pressing device. Background Technology

[0002] A tunnel boring machine (TBM), also known as a shield tunneling machine, is a specialized engineering machine for tunnel excavation. Modern TBMs integrate optics, mechanics, electronics, hydraulics, sensing, and information technology, possessing functions such as excavating and cutting soil and rock, transporting excavated material, assembling tunnel lining, and measuring and guiding. They involve multiple disciplines including geology, civil engineering, mechanical engineering, mechanics, hydraulics, electrical engineering, control, and surveying. Furthermore, they require customized design and manufacturing based on different geological conditions, demanding extremely high reliability. TBMs are widely used in tunnel projects for subways, railways, highways, municipal works, and hydropower projects.

[0003] The tail brush is a component that prevents mud and water from seeping into the tail of a tunnel boring machine. Existing technology, authorized announcement number CN202121724289.3, discloses a tail brush assembly machine that can prevent expansion before riveting. It uses an upper and lower pressing mechanism for pressing. However, the existing structure cannot accurately match the rivets for pressing in, and due to the different structures of some rivets, they can only be pressed in directly and cannot be rotated before pressing in.

[0004] Therefore, it is necessary to design a shield tail brush assembly and pressing device to solve the above problems. Utility Model Content

Each upper pressing block assembly corresponds to a set of bottom pressing blocks.

[0014] Reference Figures 1 to 4 A shield tail brush assembly and pressing device includes a device support 1, an upper pressing mechanism 2 disposed above the device support 1, and a lower pressing mechanism 3 disposed below the device support 2 and corresponding to the upper pressing mechanism 1.

[0015] The lower pressing mechanism 3 includes a pressing platform 31 mounted on the equipment support 1, a limiting component 32 mounted around the pressing platform 31, a lifting cylinder 33 located at the bottom of the pressing platform 31, a lifting block 34 driven by the lifting cylinder 33, and a plurality of bottom pressing blocks 35 mounted on the lifting block 34 and extending through the pressing platform 31.

[0016] The bottom pressure block 35 is distributed according to the position of the rivets that need to be pressed by the shield tail brush, ensuring that the bottom pressure block corresponds one-to-one with the position of a set of rivets that need to be pressed.

[0017] To facilitate the movement of the lifting block 34, guide sleeves are provided on both sides of the lifting block, and guide posts 36 are installed in conjunction with the guide sleeves. The guide sleeves and guide posts work together to guide the movement, which is then facilitated by the lifting cylinder.

[0018] The upper pressing mechanism 2 includes a slide rail assembly 21 disposed on the side of the equipment bracket 1, a drive seat 22 that can be slidably mounted on the slide rail assembly 21 via a slider, a drive cylinder 23 that drives the drive seat 22 to move up and down along the slide rail assembly, an upper pressing block assembly 24 placed inside the drive seat 22, and a rotating unit 25 that drives the upper pressing block assembly 24 to rotate. The rotating unit 25 includes a rotating motor 251, a rotating shaft 252 driven by the rotating motor 251, a rotating gear 253 placed at the shaft end of the rotating shaft 252, and a plurality of transmission gears 254 meshing with the rotating gear 253. The transmission gears 254 are installed in conjunction with the upper pressing block assembly 24 and rotate as the transmission gears 254 rotate.

[0019] The upper pressing block assembly 24 includes several sets of connecting shafts 241 for mounting with transmission gears 254, connecting rods 242 respectively hinged to the bottom of the connecting shafts, and upper pressing blocks 243 hinged to the connecting rods 242. In order to enable the rotation of the entire upper pressing block assembly 24, the connecting shafts are fitted with bearings 244, which are installed in the drive seat through bearing cooperation. To ensure the correct downward position of the upper pressure block, an upper pressure plate 4 is provided at the bottom of the drive base. The upper pressure block 243 is mounted in the upper pressure plate 4 via a bearing 41, thus ensuring that the upper pressure block 4 can rotate. Furthermore, the upper pressure plate 4 has several sets of holes for mounting the upper pressure block, with each set of holes corresponding to the holes required for assembling and pressing the shield tail brush. The upper pressure block 4 can be replaced according to product requirements to accommodate different models of shield tail brushes. If pressing is not required, the connecting rod can be removed, meaning the corresponding upper pressure block will not rotate.

[0020] In this embodiment, a limiting component is installed on the pressing platform 31. Since the pressing end of the shield tail brush has a square structure, the limiting component 32 consists of a first transverse limiting block and a first longitudinal limiting block. These two blocks are adjusted according to the position of the shield tail brush, restricting the front and side surfaces of the brush for quick and precise fitting, thus rapidly completing the positioning function. After the shield tail brush is in place, rivets are inserted into the corresponding fixing holes at the end of the brush. The upper pressing mechanism is then driven, and the driving cylinder drives the driving seat 22 downwards. The upper pressure plate 4, in conjunction with the pressing platform 31, presses down the entire shield tail brush for fixation, ensuring that the rivets are pressed in and do not shift. Simultaneously, the lower pressing mechanism 3 starts, and the lifting cylinder 33 drives the lifting block 34 to move upward. The bottom pressing block 35 and the upper pressing block 243 move up and down to press the rivets into the tail brush. Since the bottom pressing block 35 and the upper pressing block 243 correspond one-to-one with a set of rivets, all the rivets that need to be pressed can be pressed into the tail brush at one time to achieve one-time riveting. In addition, the upper pressing mechanism has a rotation function while riveting, which can further screw in the rivets and press them to further improve the fixing strength. In addition, the corresponding upper pressing plate structure and upper pressing block can be adjusted according to the model of the tail brush to adapt to the pressing of other models of products.

[0021] The advantage of this utility model is that this technical solution achieves the assembly of the shield tail brush by setting up several sets of upper pressure blocks and bottom pressure blocks to cooperate and press and fix several sets of rivets at one time. Meanwhile, the upper pressing mechanism is equipped with a rotating unit, which drives the upper pressing block assembly to rotate, further screwing the rivets in during pressing to improve the fixing strength.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
