With the increasing demand for underground engineering layout, the excavation capacity of the shaft heading machine is also constantly improved, with the main performance indicators being excavation diameter and excavation depth.

[0039] The embodiments of the present application are described in detail below with reference to the accompanying drawings, but the present application can be implemented in various different ways as defined and covered by the following.

[0040] As Figure 1The supporting device of the tunneling machine is used for supporting the tunneling machine with a large excavation diameter to facilitate equipment debugging, and comprises a supporting assembly, a connecting beam 300 and a rotating assembly. The supporting assembly comprises first and second supporting columns 100 and 101 arranged on the ground at intervals. The first supporting column 100 is provided at an end away from the ground with a first adjusting piece 200 for adjusting the height. The second supporting column 101 is provided at an end away from the ground with a second adjusting piece 208 for adjusting the height. The connecting beam 300 is fixedly connected at two ends thereof with the first and second adjusting pieces 200 and 208 respectively. The length of the connecting beam 300 can be adjusted to adapt to different interval distances between the first and second supporting columns 100 and 101. The rotating assembly is fixedly connected with the connecting beam 300 through a connecting piece 700. The central axis of the rotating assembly overlaps the center of symmetry of the connecting beam 300. The rotating assembly is used for mounting a digging arm 402 of the tunneling machine and driving the digging arm 402 to rotate. The interval distance between the first and second supporting columns 100 and 101 needs to be greater than the maximum diameter of the digging arm 402 when it is unfolded during rotation. The first and second adjusting pieces 200 and 208 are adjusted to make the lowest point of the digging arm 402 in a free state have an interval distance from the ground.

[0041] In the embodiment, in order to ensure that the first and second supporting columns 100 and 101 can be smoothly installed, a steel plate with a suitable size can be laid at the installation positions of the first and second supporting columns 100 and 101. This arrangement can indirectly increase the contact area of the supporting columns with the ground, thereby reducing the concentration of stress and preventing damage to the foundation. In addition, the first and second supporting columns 100 and 101 can be provided with a flat supporting surface, thereby ensuring that the first and second supporting columns 100 and 101 are not inclined after installation. The first supporting column 100 is detachably connected with the first adjusting piece 200 through bolts. The second supporting column 101 is detachably connected with the second adjusting piece 208 through bolts. The two ends of the connecting beam 300 are detachably connected with the first and second adjusting pieces 200 and 208 through bolts, thereby facilitating the adjustment and replacement of the components.

[0042] The size of each component of the support device of the heading machine needs to be determined according to the excavation size of the heading machine. Specifically, the interval between the first support column 100 and the second support column 101 is set, and the interval distance between the two can be adjusted according to the actual situation. At the same time, the first support column 100 is height-adjustable by installing the first adjusting part 200, and the second support column 101 is height-adjustable by installing the second adjusting part 208, so that the ground clearance of the connecting beam 300 connected with the first adjusting part 200 and the second adjusting part 208 at both ends can be changed, and the length of the connecting beam 300 can also be adjusted to meet the different interval distances between the first support column 100 and the second support column 101. When installing, the interval distance between the first support column 100 and the second support column 101 is determined according to the excavation diameter of the heading machine that needs to be debugged, and the height of the first adjusting part 200 and the second adjusting part 208 is adjusted. Specifically, the interval distance between the first support column 100 and the second support column 101 needs to be greater than the maximum diameter of the excavating arm 402 when it is unfolded during rotation, and the first adjusting part 200 and the second adjusting part 208 are adjusted to make the lowest point of the excavating arm 402 in the free state have a distance from the ground.

[0043] Specifically, when installing, first, the length of the connecting beam 300 is adjusted according to the excavation diameter of the heading machine, so that the maximum diameter of the excavating arm 402 when it is unfolded during rotation is less than the length of the connecting beam 300. The slewing assembly is connected and fixed with the connecting beam 300 through the connecting part 700, and the center axis of the slewing assembly overlaps with the center of symmetry of the connecting beam 300. Then, the arrangement positions of the first support column 100 and the second support column 101 are determined according to the excavation diameter of the heading machine and by using a total station, and the two are fixedly connected with the ground. Then, the erection height of the first support column 100 and the second support column 101 is calculated according to the excavation diameter of the heading machine, the first adjusting part 200 is arranged on the first support column 100, the second adjusting part 208 is arranged on the second support column 101, and the height of the first adjusting part 200 and the second adjusting part 208 is adjusted to make the ground clearance of the connecting beam 300 meet the design requirements, so that the lowest point of the excavating arm 402 of the slewing assembly in the free state has a distance from the ground. Finally, the two ends of the connecting beam 300 are installed with the first adjusting part 200 and the second adjusting part 208 respectively, and the excavating arm 402 is installed on the slewing assembly.

[0044] In summary, by adjusting the length of the connecting beam 300 and the height of the first adjusting member 200 and the second adjusting member 208, the entire support device is adjusted so that the excavating arm 402 mounted on the support device does not interfere with the first support column 100 and the second support column 101 in the state of rotating and unfolding, and the excavating arm 402 does not contact the ground in the state of freely drooping, thereby facilitating the installation relationship of the excavating arm 402 in the static state, facilitating the debugging of the connecting line, and facilitating the observation of the movement state of the excavating arm 402 in the rotating process. For different diameters of the shaft excavating machine, after the connecting beam 300, the first adjusting member 200 and the second adjusting member 208 are debugged to the appropriate size, the support of the shaft excavating machine of different large sizes is satisfied, thereby facilitating the debugging of the supported shaft excavating machine. Since the installation size of the support device of the shaft excavating machine can be adjusted, the support of the shaft excavating machine of different large sizes is satisfied, the adaptability is strong, and the purpose of reducing the research and development and debugging cost is achieved.
