[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0021] Reference Figure 1-Figure 3 A sliding shoe structure of an open TBM tunneling machine spraying area includes a sliding shoe body, on which two support blocks 3 are fixedly arranged. Three or more support blocks 3 can be arranged on the sliding shoe body according to actual needs. The cross section of each support block 3 is concave in shape. Each support block 3 is connected to a connecting frame 6 through a T-shaped rod 5. A fixed sleeve 8 is slidably installed on each support block 3, and a fixed rod 9 is slidably installed in the fixed sleeve 8. The fixed rod 9 passes through one end of the fixed sleeve 8 and is fixedly connected to an annular block 4. Each T-shaped rod 5 is provided with an annular groove 10 for connecting the annular block 4, and a sliding component is provided on each support block 3.

[0022] The sliding assembly includes an insertion shaft 7 slidably mounted on the support block 3, one end of the insertion shaft 7 is clamped with the fixed rod 9, a first spring 13 is sleeved on the insertion shaft 7, one end of the first spring 13 is fixedly connected to the insertion shaft 7, and the other end of the first spring 13 is fixedly connected to the inner wall of the support block 3. When the external force applied to the insertion shaft 7 is removed, under the elastic force of the first spring 13, one end of the insertion shaft 7 will penetrate the fixed sleeve 8 and be clamped with the clamping groove on one side of the fixed rod 9, which can effectively prevent the annular block 4 from being separated from the annular groove 10 on the T-shaped rod 5.

[0023] The cross section of each fixed sleeve 8 is arranged in a U-shape, and two second springs 11 are fixedly connected to the upper surface of each fixed rod 9, and each second spring 11 is fixedly connected to the upper inner wall of the fixed sleeve 8. The fixed rod 9 is pressed downward. During the downward movement of the fixed rod 9 inside the fixed sleeve 8, the two second springs 11 are deformed, and the rough surface of the annular block 4 will be tightly attached to the inner wall of the annular groove 10 after the downward movement. Two rectangular blocks 14 are fixedly connected to each fixed rod 9, and the two rectangular blocks 14 are respectively attached to the end surfaces of the two ends of the fixed sleeve 8. The two rectangular blocks 14 can prevent the fixed rod 9 and the fixed sleeve 8 from sliding relative to each other in the horizontal direction, and the fixed rod 9 can only slide relative to the fixed sleeve 8 vertically.

[0024] One side surface of each fixed sleeve 8 is fixedly connected to a limiting block 12, and the surface of the limiting block 12 fits the inner wall of the supporting block 3. The limiting block 12 can limit the moving trajectory of the fixed sleeve 8, effectively preventing the fixed sleeve 8 from being separated from the supporting block 3. The sliding shoe body includes an integrally connected guide plate 1 and a supporting plate 2. Each supporting block 3 is fixedly connected to the supporting plate 2. The boat-shaped guide plate 1 has a good guiding effect and can move stably along a trajectory in the open TBM tunneling machine spraying area. The bottom surface of the guide plate 1 has anti-slip grooves.

[0025] In the present invention, during installation, first insert one end of the connecting frame 6 into the opening of the concave support block 3, then insert one end of the T-shaped rod 5 through the connecting frame 6 and the support block 3 at the same time, until the surface of the T-shaped rod 5 fits with the outer surface of the support block 3, then pull the fixing sleeve 8 and the insertion shaft 7, the fixing sleeve 8 slides relative to the support block 3 at the same time, and the annular block 4 moves together under the transmission action of the fixing rod 9 until the surface of the limit block 12 fits with the inner wall of one side of the support block 3, at this time the annular block 4 and the annular groove 10 are located in the same vertical plane, and then press the fixing rod 9 downward, During the downward movement of the fixing rod 9 inside the fixing sleeve 8, the two second springs 11 are deformed, and the rough surface of the annular block 4 will be tightly attached to the inner wall of the annular groove 10 after the downward movement of the fixing rod 9. Then, the external force applied to the plug-in shaft 7 is removed. Under the elastic force of the first spring 13, one end of the plug-in shaft 7 will penetrate the fixing sleeve 8 and be engaged with the slot (not shown) on one side of the fixing rod 9, which can effectively prevent the annular block 4 from being separated from the T-shaped rod 5. When the sliding shoe body is damaged due to long-term use, it is convenient to disassemble, repair or replace the sliding shoe body. The operation is convenient and quick, which is conducive to the use of the structure.

[0026] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
