[0001] This utility model relates to the field of segment mold technology, and in particular to a high-precision segment mold. Background Technology

[0002] A tunnel boring machine (TBM) is a specialized piece of equipment used for tunnel excavation, employing the shield tunneling method. The TBM construction method involves the TBM simultaneously excavating and building the tunnel's "shield." TBM segments are the main assembly components in TBM construction, forming the innermost barrier of the tunnel. They resist soil pressure, groundwater pressure, and various special loads. High-strength, impermeable concrete is typically used in the production of TBM segments.

[0003] Existing high-precision tube segment molds use springs to open and close the cover plate and the mold during tube segment production, requiring the use of other equipment. Moreover, after production is completed, the internal tube segments are tightly connected to the mold, making them difficult to demold. Utility Model Content

[0004] The purpose of this utility model is to provide a high-precision tube segment mold. The cover plate and the bracket are opened and closed by an electric hydraulic rod, which does not require the use of other equipment, making opening and closing easier and operation simpler. The mold box is equipped with an inner plate, which is separate from the mold box. After the tube segment is formed in the mold box, the lower electric hydraulic rod can be used to lift the inner plate, thereby loosening and separating the internal tube segment from the mold box, which is convenient for demolding.

[0005] To achieve the above objectives, a high-precision segment mold is provided, comprising: a base, a mold box and a bracket fixedly connected to the top of the base, a cover plate provided on the top of the mold box, two cover plates symmetrically distributed left and right, the cover plates being rotatably connected to the brackets, four brackets symmetrically distributed at the four corners of the base, a support assembly provided on the brackets, the support assembly including an upper fixed shaft, an upper connecting ring, a side electro-hydraulic rod, a lower connecting ring and a lower fixed shaft, the upper fixed shaft being fixedly connected to the cover plate, the upper connecting ring being rotatably connected to the circumference of the upper fixed shaft, the side electro-hydraulic rod being fixedly connected to the circumference of the upper connecting ring, the lower connecting ring being fixedly connected to the bottom of the side electro-hydraulic rod, the lower fixed shaft being rotatably connected inside the lower connecting ring, and the lower fixed shaft being fixedly connected to the brackets.

[0006] According to the high-precision segment mold, the top of the base is fixedly connected to a lower electro-hydraulic rod. There are two lower electro-hydraulic rods, which are symmetrically distributed on the left and right. The top of the lower electro-hydraulic rod is fixedly connected to a movable plate. The top of the movable plate is fixedly connected to a side push rod and a main push rod. There are four side push rods and two main push rods. The tops of the side push rods and the main push rods are fixedly connected to an inner plate.

[0007] According to the high-precision tube segment mold, the side ejector rods are symmetrically distributed on the left and right sides of the main ejector rod.

[0008] According to the high-precision segment mold, the number of support components is set to four, and they are arranged corresponding to the bracket, which is composed of two side plates.

[0009] According to the high-precision segment mold, the inner plate is located inside the mold box, and the inner plate is arc-shaped.

[0010] According to the high-precision segment mold, the movable plate is located below the mold box.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] 1. By setting up a base, mold box, bracket, cover plate and support components, the cover plate and bracket are opened and closed by an electric hydraulic rod, which does not require the use of other equipment, making opening and closing easier and operation simpler;

[0013] 2. By setting an inner plate, a lower electro-hydraulic rod, a movable plate, a side ejector rod, and a main ejector rod, the mold box is equipped with an inner plate inside. The inner plate is separate from the mold box. After the tube sheet inside the mold box is formed, the lower electro-hydraulic rod can be used to lift the inner plate, thereby loosening and separating the internal tube sheet from the mold box, making demolding convenient.

[0025] Reference Figure 1-4This utility model discloses a high-precision segment mold, comprising: a base 1, a mold box 2 and a support 3 fixedly connected to the top of the base 1, a cover plate 4 on the top of the mold box 2, two cover plates 4 symmetrically distributed, the cover plates 4 being rotatably connected to the support 3, four support 3 symmetrically distributed at the four corners of the base 1, and four support components 5 on the support 3, corresponding to the support 3. Each support 3 consists of two side plates. Each support component 5 includes an upper fixed shaft 501, an upper connecting ring 502, a side electric hydraulic rod 503, a lower connecting ring 504, and... The lower fixed shaft 505 and the upper fixed shaft 501 are fixedly connected to the cover plate 4. The upper fixed shaft 501 is rotatably connected to the circumferential surface of the upper fixed shaft 501. The upper connecting ring 502 is fixedly connected to the circumferential surface of the upper connecting ring 502. The lower connecting ring 504 is fixedly connected to the bottom of the side electric hydraulic rod 503. The lower fixed shaft 505 is rotatably connected inside the lower connecting ring 504. The lower fixed shaft 505 is fixedly connected to the bracket 3. When the side electric hydraulic rod 503 is started synchronously, it can drive the cover plate 4 to rotate away from the side of the mold box 2. During the rotation, the cover plate 4 opens on the side of the mold box 2, so that the tubes inside the mold box 2 can be demolded.

[0026] Two lower electro-hydraulic rods 7 are fixedly connected to the top of the base 1, and they are symmetrically distributed on the left and right sides. A movable plate 8 is fixedly connected to the top of the lower electro-hydraulic rods 7. Side push rods 9 and main push rods 10 are fixedly connected to the top of the movable plate 8. There are four side push rods 9 and two main push rods 10. The side push rods 9 are symmetrically distributed on the left and right sides of the main push rods 10. An inner plate 6 is fixedly connected to the top of the side push rods 9 and the main push rods 10. The inner plate 6 is located inside the mold box 2 and is arc-shaped. The movable plate 8 is located below the mold box 2. The inner plate 6 and the mold box 2 adopt a split design. During the production of tube segments, the inner plate 6 is tightly attached to the inner wall of the mold box 2. After the internal tube segment is formed, the lower electro-hydraulic rods 7 can be activated simultaneously to lift the movable plate 8, thereby moving the inner plate 6 upward in the mold box 2, separating the internal tube segment from the mold box 2, and facilitating quick demolding.

[0027] Working principle: During production, both the side electro-hydraulic rod 503 and the lower electro-hydraulic rod 7 are connected to an external controller via wires. The external controller can control the operation of the side electro-hydraulic rod 503 and the lower electro-hydraulic rod 7 in an orderly manner. The inner plate 6 is tightly fitted to the inner wall of the mold box 2. High-strength impermeable concrete is poured into the mold box 2, and the cover plate 4 is closed. After the internal tube segments are formed, the side electro-hydraulic rod 503 is started simultaneously, causing the side of the cover plate 4 away from the mold box 2 to rotate. During the rotation, the side of the cover plate 4 located in the mold box 2 opens, and then the lower electro-hydraulic rod is started simultaneously. Rod 7 lifts the movable plate 8, thereby moving the inner plate 6 upward within the mold box 2, separating the internal tubular segments from the mold box 2 for easy and quick demolding. Finally, it should be noted that during the design and manufacture of this mold, the mold welding mechanism adopts existing heat treatment aging processes to enhance the precision and stability of the mold. At the same time, high-quality steel is used to give the mold high precision and robust durability. The above are only preferred embodiments of this utility model and are not intended to limit this utility model. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
