Description

An automated assembly device for tunneling vertical shaft segments Technical Field

[0001] This utility model relates to the technical field of shaft segment assembly, and in particular to an automated assembly device for mechanically excavated shaft segments. Background Technology

[0002] In recent years, a mechanized method for excavating vertical shafts has been gradually applied in engineering practice. This method uses a new type of shaft tunneling machine for mechanized excavation and assembles precast concrete segments to form the shaft structure. This method effectively solves the problem of limited construction space for foundation pit excavation in urban core areas. The mechanized and automated excavation improves construction efficiency and reduces manpower. However, segment assembly in this method relies solely on hoisting equipment and manual labor. The hoisting equipment is heavy and bulky, making it difficult to move in confined spaces. It is also susceptible to interference from the shaft tunneling machine's auxiliary equipment during hoisting. Furthermore, the segments require manual traction, consuming significant manpower and reducing overall construction efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the existing technology by providing an automated assembly device for mechanically excavated vertical shaft segments. This assembly device is mounted on a circular guide rail. Each of the two ends of the assembly device has a set of rollers at its top. The two rollers in each set are respectively installed in the two roller mounting slots of the guide rail and move circumferentially along the roller mounting slots. Each end of the assembly device has a lowering cylinder for connecting vertical shaft segments at its bottom. This device not only enables 360° movement of the vertical shaft segments above the shaft but also facilitates the placement of the vertical shaft segments, allowing for accurate and rapid assembly of the vertical shaft segments.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An automated assembly device for tunneling shaft segments is disclosed. The assembly device is mounted on a circular guide rail, which is connected to the tunneling machine hoist via an inverted L-shaped support arm. Roller mounting grooves are provided on both the outer and inner ring sides of the guide rail. The assembly device is arc-shaped, with a set of rollers at each of its arc-shaped top ends. Each set of rollers includes two rollers located on the outer and inner arc sides of the assembly device, respectively. The two rollers in each set are respectively installed in the two roller mounting grooves on the guide rail. The rollers are driven by a motor. A hydraulic cylinder for connecting shaft segments is provided at each of the arc-shaped bottom ends of the assembly device.

[0006] The assembly device is provided with a set of limiting wheels at each of its two ends. Each set of limiting wheels includes two limiting wheels respectively located on the outer arc side and the inner arc side of the assembly device. The two limiting wheels in each set are respectively in close contact with the outer ring side and the inner ring side of the guide rail.

[0007] The roller is located above the limiting wheel.

[0008] The base of the motor is fixed on the assembly device, and the output shaft is connected to the roller. The output shaft of the motor drives the roller to move circumferentially along the roller mounting groove.

[0009] The cylinder body of the down-pressing cylinder is fixed to the assembly device, and the telescopic rod is connected to the vertical shaft segment. The telescopic rod of the down-pressing cylinder drives the vertical shaft segment to move vertically.

[0010] The tunneling machine has three hoists along the circumference of the shaft, and the support arm has three.

[0011] The advantages of this utility model are:

[0012] (1) The segments do not require manual traction to be in place, reducing the risk of hoisting and improving construction safety;

[0013] (2) To achieve automated assembly of tunnel segments, reduce labor costs and improve construction efficiency;

[0021] The features of this utility model and other related features will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:

[0022] Example: As shown in Figures 1-4, this example relates to an automated assembly device for shaft segments in a mechanical tunneling machine. The arc-shaped assembly device 7 is mounted on a circular guide rail 6. The assembly device 7 can move circumferentially along the guide rail 6 via rollers 12. The assembly device 7 also includes a hydraulic cylinder 8 for connecting the shaft segments 9. The assembly device 7 is used for hoisting and placing the shaft segments 9, enabling not only 360° movement of the shaft segments 9 above the shaft but also placement of the shaft segments 9, allowing for accurate and rapid assembly. The guide rail 6 is connected to the tunneling machine hoist 1 via inverted L-shaped support arms 5. In this example, three tunneling machine hoists 1 are provided along the circumference of the shaft, and correspondingly, three support arms 8 are also provided. In addition to the tunneling machine hoist 1, the vertical shaft tunneling equipment also includes a shaft hoist 2 and a pipeline frame 3. The tunneling machine hoist 1, shaft hoist 2 and pipeline frame 3 are all installed on the ring beam 4. The tunneling machine hoist 1 is used to hoist the tunneling machine, the shaft hoist 2 is used to hoist the vertical shaft, and the pipeline frame 3 is used to extend and install the pipeline system on the tunneling machine.

[0023] As shown in Figures 2-4, roller mounting grooves are provided on both the outer and inner ring sides of the guide rail 6. A set of rollers 12 is provided at the top of each of the two arc-shaped ends of the assembly device 7. Each set of rollers 12 includes two rollers 12 respectively located on the outer and inner arc sides of the assembly device 7. The two rollers 12 of each set of rollers 12 are respectively installed in the two roller mounting grooves of the guide rail 6. The rollers 12 are driven by a motor 10. The base of the motor 10 is fixed on the assembly device 7, and the output shaft is connected to the rollers 12. The output shaft of the motor 10 drives the rollers 12 to move circumferentially along the roller mounting groove. The assembly device 7 has a set of limiting wheels 11 at each of its two ends. Each set of limiting wheels 11 includes two limiting wheels 11 located on the outer arc side and the inner arc side of the assembly device 7, respectively. The two limiting wheels 11 of each set are closely attached to the outer ring side and the inner ring side of the guide rail 6, respectively. The limiting wheels 11 can limit the assembly device 7 to prevent it from falling off the guide rail 6. In this embodiment, the roller 12 is located above the limiting wheels 11.

[0024] As shown in Figures 2-4, each end of the assembly device 7 is equipped with a pressing cylinder 8 for connecting the vertical shaft segment 9. The cylinder body of the pressing cylinder 8 is fixed to the assembly device 7, and the telescopic rod is connected to the vertical shaft segment 9. The telescopic rod of the pressing cylinder 8 drives the vertical shaft segment 9 to move vertically. The pressing cylinder 8 provides a certain downward pressure during the installation of the vertical shaft segment 9 to reduce misalignment between the vertical shaft segments 9 and ensure the assembly quality of the vertical shaft segment 9.

[0025] The beneficial technical effects of this embodiment are as follows:

[0026] (1) The segments do not require manual traction to be in place, reducing the risk of hoisting and improving construction safety;

[0027] (2) To achieve automated assembly of tunnel segments, reduce labor costs and improve construction efficiency;

[0028] (3) The device provides downward pressure for the installation of segments, reduces misalignment between segments, and improves the quality of segment assembly.

[0029] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
