Description

Technical Field

[0001] This utility model belongs to the field of construction positioning technology, and relates to vertical shaft slipform construction, especially a positioning device for hydraulic vertical shaft slipform construction. Background Technology

[0002] Slipform construction technology for shafts is a technique used in underground engineering and the construction of basements in high-rise buildings. It is mainly applicable to the construction of shafts, underground civil defense projects, underground passages, and other structures. This technology enables the continuous pouring of concrete structures through a slipform system. The mold rises slowly during construction, and the concrete is poured continuously as construction progresses, resulting in an integrated, seamless concrete wall. In hydraulic engineering construction, shafts are important foundation structures. To ensure the construction quality and structural stability of shafts, slipform construction technology has become a common practice for concrete pouring. Slipform construction can significantly improve construction efficiency and ensure the continuity and uniformity of concrete pouring. Usually, the mold needs to be positioned, thus requiring a positioning device for slipform construction of hydraulic shafts.

[0003] Existing methods mostly rely on traction equipment to lift and position the slipform. During this process, the slipform is prone to swaying, leading to instability in its position. When the slipform sways, operators need to use auxiliary tools to make multiple adjustments to ensure that the slipform can be positioned relatively accurately. This adjustment process is not only difficult to operate, but also cumbersome and inconvenient, easily leading to a waste of human resources and a reduction in construction efficiency. In addition, in traditional slipform construction, the rise height of the slipform usually relies on manual measurement with a measuring tape. This method is affected by various factors, especially the error of the control point and the error of manual operation. This leads to insufficient accuracy of monitoring data and is prone to large errors, which affects the smooth movement of the slipform and precise pouring. If the monitoring data is unreliable, it may lead to uneven concrete pouring, structural defects, and other problems, thus affecting the overall construction quality of the shaft. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a positioning device for slipform construction of hydraulic shafts. The technical problem to be solved by this utility model is: how to achieve precise positioning of the slipform body.

[0005] The objective of this utility model can be achieved through the following technical solutions: A positioning device for slipform construction of hydraulic shafts includes a base with a shaft at the center of the top of the base. A slipform body is housed inside the shaft, and a first positioning rod is positioned at the center of the shaft's interior. The bottom of the first positioning rod is inserted to the center of the bottom of the shaft. A first positioning mechanism for positioning the slipform body is provided on the side wall of the first positioning rod. Multiple second positioning mechanisms for positioning the slipform body are arranged in a circular pattern at equal intervals on the inner side wall of the slipform body. A circular plate is provided on the top of the base, with one end of the first positioning rod penetrating the top of the circular plate. A fixing mechanism for fixing a circular plate is provided. A sleeve is provided through the top of the circular plate and is fitted onto the side wall of the first positioning rod. The outer side wall of the first positioning rod is provided with a scale. A traction mechanism for pulling the sliding mold body is provided at the top of the circular plate. During use, the first positioning mechanism and the first positioning rod are used to center the sliding mold body. Then, the second positioning mechanism can ensure that the sliding mold body is always in a vertical state during movement, effectively preventing displacement of the sliding mold body, thereby ensuring its positional stability and improving the positioning accuracy.

[0006] As a further embodiment of this utility model, the first positioning mechanism includes an annular sleeve, which is sleeved on the side wall of the first positioning rod and located below the sleeve.

The annular sleeve and the multiple connecting rods are fixed in advance so that the center point of the sliding mold body and the center point of the annular sleeve are located at the same position. During installation, the annular sleeve is sleeved on the side wall of the first positioning rod so that the circular position of the sliding mold body is on the same vertical line as the center position of the shaft, thus performing preliminary positioning treatment on the sliding mold body.

[0007] As a further embodiment of this utility model, the second positioning mechanism includes a second positioning rod, which is disposed at the bottom of the vertical shaft. One end of the second positioning rod is inserted into the base, and the second positioning rod is located inside the sliding mold body.

This can effectively prevent the sliding mold body from rotating during the descent process, so as to ensure that the sliding mold body can be positioned relatively accurately without the need for worker adjustment. The operation is simple and convenient for positioning.

[0008] As a further embodiment of this utility model, the bottom of the circular plate is fixed with multiple locking posts at equal intervals in a circular pattern. The tops of the multiple second positioning rods are each provided with a circular hole, and the multiple circular holes correspond one-to-one with the multiple locking posts. The fixing mechanism includes four threaded rods, which are respectively fixed at the four corners of the top of the base. The sidewall of the vertical shaft is fixed with four support plates at equal intervals in a circular pattern. One end of each of the four support plates has a through hole, and the four threaded rods are located inside the four through holes. Threaded caps are installed on the sidewalls of the four threaded rods, and the four threaded caps are located on the tops of the four support plates. When the circular plate is placed on the top of the base, the four support plates are respectively fitted onto the sidewalls of the four threaded rods, and the multiple locking posts are located inside the multiple circular holes, positioning the multiple second positioning rods and preventing them from shifting.

[0009] As a further embodiment of this utility model, the traction mechanism includes four steel wires, which are equidistantly and circularly fixed to the top of the sliding mold body.

Rollers are rotatably connected to the inner sidewalls of the four U-shaped brackets, and the four steel wires and four rollers correspond one-to-one. The same connecting block is fixed to the bottom of the four steel wires, and a lifting ring is fixed to the top of the connecting block. The sliding mold body is lifted by a crane in conjunction with the connecting block, the lifting ring, and the four steel wires, thereby raising and lowering the sliding mold body.

[0016] In this embodiment, the first positioning mechanism includes an annular sleeve 15, which is sleeved on the side wall of the first positioning rod 12 and located below the sleeve 13. Multiple connecting rods 16 are fixed in a circular pattern at equal intervals on the outer side wall of the annular sleeve 15, and one end of each of the multiple connecting rods 16 is fixed to the sliding mold body 10.

[0017] In this embodiment, the second positioning mechanism includes a second positioning rod 11, which is disposed at the bottom of the vertical shaft 2. One end of the second positioning rod 11 is inserted into the base 1, and the second positioning rod 11 is located inside the sliding mold body 10. A protrusion 17 is fixed on the inner side wall of the sliding mold body 10. A groove 18 is provided on the side wall of the second positioning rod 11 near the sliding mold body 10, and the protrusion 17 and the groove 18 are adapted to each other.

[0018] In this embodiment, the bottom of the circular plate 3 is fixed with multiple locking posts 22 at equal intervals in a circular shape, and the top of the multiple second positioning rods 11 is provided with circular holes 19, and the multiple circular holes 19 and the multiple locking posts 22 correspond one-to-one.

[0019] In this embodiment, the fixing mechanism includes four threaded rods 5, which are respectively fixed at the four corners of the top of the base 1. Four support plates 4 are fixed in a circular shape at equal intervals on the side wall of the shaft 2. Each of the four support plates 4 has a through hole 23 at one end of its top, and the four threaded rods 5 are respectively located inside the four through holes 23. Threaded caps 9 are installed on the side walls of the four threaded rods 5, and the four threaded caps 9 are respectively located on the top of the four support plates 4.

[0020] In this embodiment, the traction mechanism includes four steel wires 8, which are fixed in a circular pattern at equal intervals to the top of the sliding mold body 10. Four U-shaped brackets 20 are fixed in a circular pattern at equal intervals to the top of the circular plate 3. Rollers 21 are rotatably connected to the inner sidewalls of the four U-shaped brackets 20. The four steel wires 8 and the four rollers 21 correspond one-to-one. The same connecting block 6 is fixed to the bottom of the four steel wires 8, and a lifting ring 7 is fixed to the top of the connecting block 6.

[0021] The working principle of this utility model is as follows: During use, the annular sleeve 15 and multiple connecting rods 16 are pre-fixed so that the center point of the sliding mold body 10 and the center point of the annular sleeve 15 are in the same position. During installation, the first positioning rod 12 is pre-inserted deep into the center of the bottom of the vertical shaft 2, and multiple second positioning rods 11 are fixed deep into the bottom of the vertical shaft 2. The sliding mold body 10 is lifted by a crane with the help of connecting block 6, lifting ring 7 and four steel wires 8, and slowly placed into the vertical shaft 2. During the placement process, the annular sleeve 15 is fitted onto the side wall of the first positioning rod 12, so that the circular position of the sliding mold body 10 and the center position of the vertical shaft 2 are on the same vertical line, which performs preliminary limiting treatment on the sliding mold body 10. At the same time, multiple protrusions 17 are respectively located in multiple grooves 18, which can effectively prevent the sliding mold body 10 from rotating during the descent, ensuring that the sliding mold body 10 can be positioned relatively accurately without the need for worker adjustment. The operation is simple and convenient for positioning. When the sliding mold body 10 is in the vertical shaft 2... When the inner bottom contact no longer moves, place the circular plate 3 on top of the base 1. At this time, the four support plates 4 are respectively fitted onto the side walls of the four threaded rods 5, and the multiple locking posts 22 are respectively located inside the multiple circular holes 19 to position the multiple second positioning rods 11. Then, tighten the four threaded caps 9 onto the four threaded rods 5, thus completing all the installation work. During pouring, when it is necessary to move the slipform body 10 upward, the slipform body 10 is lifted by a crane with the help of the connecting block 6, the lifting ring 7 and the four steel wires 8. During the upward movement of the slipform body 10, the annular sleeve 15 moves upward along the first positioning rod 12, thereby driving the sleeve 13 to move upward. Since the outer wall of the sleeve 13 is provided with a scale 14, the height of the slipform body 10 can be determined according to the scale 14 exposed at the bottom of the circular plate 3. There is no need for workers to use measuring tools to measure, which effectively avoids large errors, improves the accuracy of data, prevents unevenness and structural defects during concrete pouring, and improves the construction quality of the shaft 2.

[0022] In summary, in this utility model, during use, the first positioning mechanism, in conjunction with the first positioning rod 12, performs center positioning processing on the sliding mold body 10. Then, the second positioning mechanism ensures that the sliding mold body 10 remains vertical during movement, effectively preventing displacement of the sliding mold body 10, thereby ensuring its stable position, improving positioning accuracy, and guaranteeing the construction quality of the shaft 2.
