The lifting drive component 3 can adopt a hydraulic component composed of a cylinder piston rod or the like or a component with equivalent lifting and retracting functions. The lifting drive component 3 is used to provide space for the removal of the support frame 2 after the main engine 14 of the tunnel boring machine and the platform are transported to the site; after the support frame 2 is removed, the cylinder retracts and lowers the platform to the culvert surface for easy translation to the work station; during the construction process of the main engine 14 of the tunnel boring machine, the posture of the platform is adjusted by the extension and retraction of each cylinder to achieve tunnel excavation at various angles.

[0064] The present invention also provides a method for adjusting the posture of a main engine of a tunnel boring machine, such as Figure 4~Figure 8 As shown, the main machine 14 of the tunnel boring machine includes the following steps when being transported in the main tunnel:

[0065] The main machine attitude adjustment platform of the tunnel boring machine as described above is installed in the starting shaft of the main tunnel;

[0066] Place the main machine 14 of the tunnel boring machine on the platform plate 1;

[0067] The transport vehicle 15 moves to the bottom of the platform plate 1, extends the lifting drive member 3 to support the transport vehicle 15, removes the two sets of the connecting members 5, separates the platform plate 1 from the support frame 2, moves the support frame 2 to a predetermined position, and then retracts the lifting drive member 3 to lower the platform plate 1 and place it on the transport vehicle 15;

[0068] The transport vehicle 15 moves to the predetermined position, the lifting drive member 3 is extended to support the transport vehicle 15, two sets of the connecting members 5 are installed to connect the platform plate 1 with the support frame 2, and then the lifting drive member 3 is retracted, and the transport vehicle 15 moves away from under the platform plate 1;

[0069] Place the translation device under the platform plate 1, extend the lifting drive member 3 to support the tunnel culvert surface, disassemble the two sets of the connecting members 5 to separate the platform plate 1 from the support frame 2, remove the support frame 2, retract the lifting drive member 3, and lower the platform plate 1 to place it on the track slide 8;

[0070] like Figure 10~Figure 13 As shown, A represents the translation direction of the main machine 14 of the tunnel boring machine, and B represents the center line of the main tunnel. The main machine 14 of the tunnel boring machine includes the following steps when it translates in the main tunnel:

[0071] Connect the first end of the translation driving member 10 to the supporting base plate 7, and connect the second end of the translation driving member 10 to the platform plate 1;

[0072] Extend the translation driving member 10 to make the track slide plate 8 under the platform plate 1 slide on the supporting bottom plate 7;

[0073] Remove the connection between the first end of the translation driving member 10 and the supporting base plate 7;

[0074] Retract the translation driving member 10 and change the position where the first end of the translation driving member 10 is connected to the supporting base plate 7;

[0075] The translation driving member 10 is extended again to make the track slide plate 8 under the platform plate 1 slide on the supporting bottom plate 7 until it reaches the target position.

[0076] Preferably, the steps for adjusting the pitch angle of the tunnel boring machine main body 14 include: when it is necessary to adjust the tunneling height of the tunnel boring machine main body 14, first adjust the length of the lifting drive component 3, and then adjust the length of the lifting rod to the same height; when it is necessary to adjust the tunneling angle of the tunnel boring machine main body 14, adjust the platform plate 1 to the target inclination angle through the lifting drive component 3, and during this process, the ball head 403 rotates in the spherical groove in the support seat 404 to maintain the target inclination angle for tunneling construction.

[0077] Specifically, Fig.14 and Fig.15 As shown, C represents the direction of the communication channel, and D represents the direction of the main tunnel. When adjusting the pitch angle of the main machine 14 of the tunnel boring machine, there are two directions of construction angle adjustment conditions, corresponding to the inclination angle α of the platform plate 1 along the communication channel direction (the width direction of the platform plate 1) and the inclination angle β along the main channel direction (the length direction of the platform plate 1);

[0078] The spacing and stroke difference of a single lifting drive component (cylinder) is tangentially related to the adjustment angle in this direction:

[0079] ;

[0080] ;

[0081] Among them, W represents the distance between the two lifting drive components (cylinders) in the width direction of the platform plate 1, L represents the center distance of the lifting drive components (cylinders) in the length direction of the platform plate 1, and H1, H2, H3, and H4 respectively represent the stroke of each lifting drive component (cylinder).

[0082] The angle and cylinder stroke that need to be adjusted are preliminarily determined based on the actual project needs. The specific construction process program controls the extension and retraction speed and stroke of the lifting drive component (cylinder). Finally, the stroke of the lifting drive component (cylinder) is fine-tuned on site based on construction needs.

[0083] like Fig.14 and Fig.15 As shown, the present invention can realize the inclination adjustment of the connecting channel direction C and the main tunnel direction D, and the adjustment range is ±10° horizontally and ±5° in pitch. Fig.14 In the middle, the working condition is tilted to the right at an angle of α, and the angle α is 1.75°. Fig.15 The middle one is an operating condition in which the main tunnel is tilted to the right at an angle of β, and the angle β is 2.3°. It can be seen that the present invention can adjust various horizontal and pitch angles to meet different excavation construction working conditions at up, down, left, and right angles.

[0084] Preferably, Figure 16~Figure 19 As shown, when the host platform needs to be moved and transported in a small range or a short distance, a walking mechanism 16 can be installed at the bottom of the platform board 1. A support beam 17 is fixed on the walking mechanism 16. The platform board 1 is detachably connected to the bottom of the support beam 17 through a connecting component 18. The structure of the connecting component 18 can adopt the same structure as the connecting member 5. In the connected state, the platform board 1 is located below the support beam 17, and the connecting component 18 is connected between the platform board 1 and the support beam 17. A group of walking mechanisms 16 are respectively provided at the front and rear ends of the platform board 1. A support beam 17 is provided on the top of each group of walking mechanisms 16. The support beam 17 mainly bears the load of the host platform, and the load of the host platform is transmitted to the walking mechanism 16 through the support beam 17.

[0085] The walking mechanism 16 includes a walking frame 1602, a walking drive 1603, a walking direction-adjusting member 1604 and two walking wheels 1601. The walking frame 1602 is connected to the bottom of the support beam to provide support for the host platform. The two walking wheels 1601 can be rotatably connected to the bottom of the walking frame 1602 through a rotating shaft. The walking direction-adjusting member 1604 is hinged to the rotating shaft of the two walking wheels. The walking direction-adjusting member 1604 can adopt a linear telescopic driving member such as an oil cylinder, an air cylinder or an electric telescopic rod. Under the action of the telescopic driving of the walking direction-adjusting member 1604, the two walking wheels 1601 can be rotated, thereby achieving the purpose of walking direction-adjusting. The walking drive 1603 is fixed to one of the walking wheels 1601, and the walking drive 1603 is drivingly connected to the two walking wheels 1601 to provide walking power for the walking wheels 1601.

[0086] The platform and method for adjusting the posture of the main engine of the tunnel boring machine of the present invention can realize the lifting and lowering of the main engine of the tunnel boring machine 14 through the main engine platform, so as to facilitate the placement of the main engine of the tunnel boring machine 14 on the transport vehicle 15 for long-distance transportation, and can realize the short-distance translation of the main engine of the tunnel boring machine 14 through the translation device. The cooperation between the ball head 403 of the mechanical locking component 4 and the support seat 404 can adapt to the working conditions of various construction inclination angles of the main engine of the tunnel boring machine 14, and solve the technical problem that the tunnel boring machine for the construction of the main tunnel communication channel in the prior art cannot be hoisted in the tunnel, thus causing the tunnel boring machine main engine 14 to be transported, disassembled, translated, and the construction posture adjustment is limited in the tunnel.
