[0025] As Figures 1 to 3 shown, the present invention provides a construction method for jumbo backhaul adjustment, which is used for the construction of a side channel of a main tunnel by a jumbo unit. The jumbo unit includes a jumbo main body 10 and an adjustment frame assembly 20 installed on the jumbo main body 10. The adjustment frame assembly 20 is used to carry and adjust the carried object. The carried object includes a sleeve assembly 70. Further, the carried object also includes a tunnelling main body 80, and the tunnelling main body 80 is installed on the sleeve assembly 70.

[0026] The jumbo unit carries the sleeve assembly 70 to move, and the jumbo unit can adjust the angle and position by connecting to the tunnel segment 90 through a backhaul adjustment mechanism. Among them, the backhaul adjustment mechanism includes an adjustment wheel assembly 30 and at least two tie rod assemblies 40.

[0027] The sleeve assembly 70 is installed on the adjustment frame assembly 20 and can move under the drive of the adjustment frame assembly 20 to adjust the swing angle and circumferential angle of the sleeve assembly 70 in the left - right direction. The jumbo main body 10 is the support part of the tunnelling equipment, and the jumbo main body 10 can adjust the fixed height of the sleeve assembly 70 through lifting movement. Among them, the direction in which the sleeve assembly 70 moves towards the tunnelling area is the front, the center line direction of the tunnel is the left - right direction, and the gravity direction is the up - down direction.

[0028] Among them, the construction method for jumbo backhaul adjustment includes the following steps: S101, control the adjustment wheel assembly 30 to move the jumbo main body 10 to a predetermined position corresponding to the area to be tunnelled 91.

[0029] The adjustment wheel assembly 30 is installed below the trolley main body 10 and can guide the trolley device to move in the main tunnel to adjust the position of the sleeve assembly 70. Multiple side channels need to be opened in the main tunnel. Before the tunneling construction of each side channel, the sleeve assembly 70 needs to be installed for positioning and supporting the tunneling main body. Optionally, multiple trolley devices can be provided. The tunneling main body and the sleeve assembly 70 are carried by one trolley device to move to the tunneling area 91 of one of the side channels for debugging, and other trolley devices carry the sleeve assembly 70 to move to other side channels for pre-installation of the sleeve assembly 70.

[0030] The movement direction of the adjustment wheel assembly 30 intersects with the tunneling center line of the tunneling main body 80, and the carried object can be adjusted left and right. Optionally, the adjustment wheel assembly 30 can adopt an active traction structure, that is, some of the adjustment wheel assemblies 30 adopt power wheel groups. Optionally, the adjustment wheel assembly 30 includes at least one set of driving wheels. The power wheel group can tow the trolley main body 10 to move to fine-tune the tunneling main body 80. Optionally, the adjustment wheel assembly 30 can adopt a passive traction mechanism, that is, the adjustment wheel assembly 30 adopts a non-powered wheel group, and a traction device is controlled to tow the trolley device to move. An external traction device or thrust device drives the trolley main body 10 to move, so as to realize the left and right movement of the tunneling main body 80, and the movement direction of the trolley device intersects with the center line direction of the tunneling area 91. The traction device or thrust device can adopt a power cart, a thrust oil cylinder, a pull oil cylinder, etc.

[0031] S102. Connect the trolley main body 10 to the tunnel segment 90 through at least two sets of tie rod assemblies 40. The tie rod assemblies 40 are arranged on one side of the trolley main body 10 facing the tunneling area 91. After the trolley main body 10 is adjusted in place in the left and right directions through the adjustment wheel assembly 30, the trolley main body 10 is connected to the tunnel segment 90 through the tie rod assemblies 40. The tie rod assemblies 40 have the ability to expand and contract in the length direction and can drive the trolley main body 10 to move in the front and back directions.

[0032] S103. Control the tie rod assemblies 40 to adjust the movement of the trolley main body 10 in the direction facing the tunneling area 91. After the trolley main body 10 is adjusted in place in the left and right directions through the adjustment wheel assembly 30, there is a spacing distance between the tunneling main body 80 and the tunnel segment 90. Among them, the tie rod assemblies 40 also need to adjust the position of the tunneling main body 80 in the front and back directions so that the sleeve assembly 70 approaches and aligns with the fixed position of the tunnel segment 90.

[0033] At least two tie rod assemblies 40 are distributed on both sides of the sleeve assembly 70. Each tie rod assembly 40 is respectively connected to the trolley main body 10 and the tunnel segment 90. Among them, at least two tie rod assemblies 40 pull the trolley main body 10, and the sleeve assembly 70 is aligned to the tunneling area 91 of the tunnel segment 90.

[0034] S104. Control the movement of the trolley main body 10 and the adjustment frame assembly 20 to adjust the attitude of the carried object so that the carried object adapts to the area 91 to be excavated.

[0035] Among them, control the trolley main body 10 to adjust the height attitude of the carried object; control the adjustment frame assembly 20 to adjust the inclination attitude of the carried object. The trolley main body 10 is provided with a support mechanism, and the support mechanism uses a hydraulic device to realize the control of the lifting height of the trolley main body 10. Further, the support mechanism can realize the adjustment of the pitching angle of the trolley main body 10 in the front-rear direction, so as to adjust the front-rear pitching angle of the carried object.

[0036] The carried object is placed on the adjustment frame assembly 20, and the adjustment frame assembly 20 can adjust the swing angle of the sleeve assembly 70 in the horizontal direction, so that the sleeve assembly 70 can perform fine and efficient angle adjustment to adapt to the tunnel segments 90 with different curvatures at the area 91 to be excavated. For example, the adjustment frame assembly 20 is provided with a twisting member, and the twisting member is connected to the sleeve assembly 70 to drive the twisting member to rotate.

[0037] In the above steps S103 and S104, they can be comprehensively executed, and this comprehensive execution includes the alternate execution or step-by-step execution of S103 and S104 to gradually realize the alignment and calibration of the sleeve assembly 70.

[0038] Alternatively, step S104 is before step S103 to first perform the position adjustment of the sleeve assembly 70 and then perform the adjustment in the front-rear direction.

[0039] The tie rod assembly 40 can drive the trolley main body 10 to approach the tunnel segment 90 in the excavation area, and then combine the trolley main body 10 and the adjustment frame assembly 20 to accurately adjust the sleeve assembly 70, with high adjustment convenience.

[0040] Further, the trolley main body 10 moves in the main tunnel through the adjustment wheel assembly 30, so that the trolley main body 10 carrying the sleeve assembly 70 moves to different side passage construction positions in the main tunnel, improving the use efficiency of the trolley main body 10 and reducing the debugging cost of the sleeve assembly 70 in different excavation areas.

[0041] In an embodiment, the trolley device includes a support assembly 50 located at the bottom of the trolley main body 10, and the trolley main body 10 slides on the support assembly 50. The support assembly 50 provides a support and sliding base platform for the trolley main body 10 to guide the trolley main body 10 to slide along the plane of the support assembly 50.

[0042] Optionally, the support assembly 50 is two groups of cross beam assemblies arranged in parallel, and the trolley main body 10 slides on the cross beam assemblies for sliding connection.

[0043] Optionally, the support assembly 50 is two groups of frame assemblies or steel plate assemblies arranged in parallel, and the trolley main body 10 slides on the frame assemblies or steel plate assemblies.

[0044] The support assembly 50 is located on the lower side of the trolley body 10 and near both ends, and both ends of the support assembly 50 extend beyond the width of the trolley body 10. The support assembly 50 can reduce the moving resistance of the trolley body 10 and maintain the stability of the sliding plane. The tie rod assembly 40 can guide the trolley body 10 to slide in a specific direction.

[0045] In step S103, controlling the tie rod assembly 40 to adjust the movement of the trolley body 10 towards the area to be excavated 91 includes the following: Controlling the telescopic parts of the tie rod assemblies 40 on both sides of the trolley body 10 to move alternately, so as to drive the corresponding side of the trolley body 10 to move along the support assembly 50 towards the area to be excavated 91; and / or, Controlling the telescopic parts of the tie rod assemblies 40 on both sides of the trolley body 10 to move synchronously, so as to drive the trolley body 10 to translate along the support assembly 50 towards the area to be excavated 91.

[0046] The tie rod assembly 40 has the function of telescopic change. Among them, one end of the tie rod assembly 40 is connected to the tunnel segment 90 to form a fixed end; the other end of the tie rod assembly 40 is connected to the trolley body 10 to form a movable end. When the tie rod assembly 40 shortens, the trolley body 10 moves laterally towards the tunnel segment 90. When both sides of the tie rod assembly 40 move, the trolley body 10 can achieve translational movement.

[0047] The telescopic movement of the tie rod assembly 40 includes the unilateral movement of the trolley body 10. The trolley body 10 can deflect on the upper plane of the support assembly 50, thereby adjusting the center line angle of the sleeve assembly 70. It can also reduce the distance between one side of the sleeve assembly 70 and the tunnel segment 90. Further, the two groups of tie rod assemblies 40 extend and contract synchronously, so that the platform body translates closer to the tunnel segment 90.

[0048] Among them, the alternating movement of the tie rod assembly 40 and the synchronous movement of all the tie rod assemblies 40 are combined to achieve overall movement.

[0049] Further preferably, at least two groups of tie rod assemblies 40 are symmetrically distributed on the trolley body 10. The tie rod assemblies 40 are symmetrically stressed, which can facilitate the control of the telescopic amount. Preferably, the symmetry plane of the two groups of tie rod assemblies 40 coincides with the center line of the carried object, so as to facilitate the precise adjustment of the center line of the carried object.

[0050] In order to further improve the flexibility of the movement of the trolley body 10, in one embodiment, a driving component is installed on the supporting component 50. The driving component can be used as the most rearward thrust output part to push the trolley body 10 to move on the supporting component 50. The driving component telescopically moves and pushes against the trolley body 10. The driving component is a hydraulic cylinder component. The telescopic movement of the hydraulic cylinder component can push the trolley body 10 to slide along the supporting component 50, and can cooperate with the pull rod component 40 to adjust the movement posture of the trolley body 10.

[0051] Preferably, a reaction seat is welded and fixed on the supporting component 50, and the driving component is installed on the reaction seat and abuts against the trolley body 10. The driving component pushes the trolley body 10 to move, and the pull rod component 40 applies a pulling force to the trolley body 10, so as to realize the combined force on the trolley body 10.

[0052] Among them, the driving component and the pull rod component 40 are respectively located on opposite sides of the trolley body 10; Control the driving component to push the trolley body 10 to move in the direction of the area to be tunnelled 91; Control the combined movement of the pull rod component 40.

[0053] Two groups of driving components are provided, which are distributed on both sides of the sleeve component 70. Each group of driving components is paired with the corresponding pull rod component 40, and is distributed on the front and rear sides of the sleeve component 70. The driving component provides driving force, can cooperate with the pull rod component 40 to adjust the movement posture of the trolley body 10, reduce the required pulling force of the pull rod component 40, and reduce the required driving force of the pull rod component 40.

[0054] As Figures 1 to 3 shown, the pull rod component 40 connects the trolley body 10 and the tunnel segment 90. By telescopically adjusting the position and angle in the front and rear directions through the pull rod component 40, the traction trolley body 10 is moved to adjust the tunnelling angle, so as to realize the convenient alignment of the sleeve component 70 and the area to be tunnelled 91, with high alignment efficiency and low cost. The pull rod component 40 includes a connecting seat 43, a pull rod frame 41 and an adjustable connecting piece 42 installed on the pull rod frame 41. The adjustable connecting piece 42 drives the pull rod frame 41 to telescopically move.

[0055] In step S102, connecting the trolley body 10 to the tunnel segment 90 through at least two groups of pull rod components 40 includes: Fixing the connecting seat 43 to the tunnel segment 90; the connecting seat 43 is fixedly connected to the tunnel segment 90 so that the two are integrated. The tunnel segment 90 provides a fixed foundation for the connecting seat 43 to keep the connecting position unchanged.

[0056] Connect the adjustable connector 42 to the connection seat 43. The adjustable connector 42 has the function of telescopic adjustment and pressurization. Among them, the adjustable connector 42 is a power telescopic member. When the adjustable connector 42 extends, it can push the trolley main body 10 towards the tunnel segment 90, which can not only form preloading but also adjust the swing angle of the trolley main body 10 relative to the tunnel segment 90. The adjustable connector 42 is configured as a hydraulic device. The hydraulic device is sleeved on the pull rod frame 41, and the telescopic movement of the hydraulic device pushes the trolley main body 10 towards the tunnel segment 90 to achieve position adjustment. Optionally, the adjustable connector 42 is configured as a screw mechanism. The screw mechanism includes a screw and a nut connected to the screw. One of the screw or the nut is connected to the sleeve assembly 70, and the other is connected to the connection seat 43 to form a manually driven connection.

[0057] Connect the pull rod frame 41 to the trolley main body 10 and the adjustable connector 42. Preferably, the pull rod frame 41 is movably connected to the trolley main body 10 to form an angular swing adjustment. Optionally, the pull rod frame 41 includes a base fixed to the trolley main body 10 and a connecting rod inserted and connected to the base. One end of the connecting rod passes through the base and is connected to the tunnel segment 90. The connecting rod can rotate around the base and can also achieve a reliable pulling connection.

[0058] Fix the connection seat 43 to the tunnel segment 90. Among them, the connection method between the connection seat 43 and the tunnel segment 90 includes but is not limited to the following embodiments.

[0060] Optionally, the connection seat 43 is connected to the tunnel segment 90 by casting. After the tunnel segment 90 is assembled, a cast-in-place ring beam is realized on the tunnel segment 90, and the connection seat 43 is located in the cast-in-place ring beam to form a part of the tunnel segment 90.

[0061] Optionally, the connection seat 43 is configured as a screw hole seat or a screw column, and the connecting member connecting the connection seat 43 to the tunnel segment 90.

[0062] As Figure 4 shown, the trolley device can move in the main tunnel through its own adjustment wheel assembly 30, or the trolley device can be transported to the vicinity of the excavation area 91 by a transportation device. Preferably, the transportation device can be used when the trolley device first enters the main tunnel or when the opening distance to the next side passage is extremely large to reduce the construction cost.

[0063] In one embodiment, before controlling the adjusting wheel assembly 30 to drive the trolley body 10 to move to a relative position of the area to be excavated 91, the following steps are also included: The trolley device is transported to the area to be excavated 91 by the transport equipment, and the transport equipment is preliminarily adjusted to the periphery of the area to be excavated 91. The transport equipment transports the trolley device without the need for reciprocating accurate positioning, thereby reducing the adjustment requirements for the transport equipment.

[0064] The leg assembly 60 connected to the support assembly 50 is supported to the tunnel plane; the leg assembly 60 supports the support assembly 50, so that the leg assembly 60 supports the trolley device through the support assembly 50, so as to suspend the trolley device.

[0065] The transport device is driven to descend and detach from the trolley device; the transport device descends and detaches from the support assembly 50, so that the trolley device can be suspended. The transport device can run away from the bottom of the trolley device, and the trolley device can be raised and lowered.

[0066] The center of the load of the control vehicle device is lowered to adapt to the area to be excavated 91.

[0067] The descent method of the trolley device includes but is not limited to the following two methods: 1. The support leg assembly 60 is detachably connected to the support assembly 50, wherein the support leg assembly 60 is supported under the support assembly 50. Accordingly, the control of the center of the load of the vehicle device to be lowered to the area 91 to be adapted for excavation includes: The support mechanism of the control trolley device extends out to abut against the tunnel plane; Detach the leg assembly 60 from the support assembly 50; Control the support mechanism to descend.

[0068] The supporting mechanism of the trolley device descends to support the trolley device, so that the support leg assembly 60 does not participate in the support of the trolley device. Afterwards, the support leg assembly 60 can be removed and the trolley device is mounted on the support assembly 50. The support assembly 50 supports the trolley device, so that the pull rod assembly 40 adjusts the position and posture of the trolley device.

[0069] Second, the support leg assembly 60 is installed on the support assembly 50 to form an integral connection. The support leg assembly 60 can be raised and lowered to adjust the height position of the trolley device.

[0070] The outrigger assemblies 60 are respectively connected to both ends of the support assembly 50, and the outrigger assemblies 60 support the lifting height of the adjustment trolley main body 10. The outrigger assemblies 60 can be adjusted in lifting, assisting the trolley main body 10 to disengage from the transport vehicle. The trolley main body 10 combines with the tie rod assembly 40 to adjust the attitude, enabling fine adjustment. The outrigger assemblies 60 are fixedly installed below or on one side of the support assembly 50, and the outrigger assemblies 60 have a lifting movement so that the outrigger assemblies 60 can support the trolley main body 10. For example, the outrigger assemblies 60 are configured as hydraulic mechanisms to form lifting supports.

[0071] After the transport vehicle disengages, the lifting assembly extends to raise the trolley main body 10, thus facilitating the retraction of the outrigger assemblies 60. The lifting assembly can adjust the overall height of the trolley main body 10 so that the central height of the sleeve assembly 70 coincides with the central position of the area to be tunnelled 91. Then, through the combined drive of the tie rod assembly 40 and the drive assembly, the trolley main body 10 is moved to adjust the attitude, thereby changing the tunnelling angle of the tunnelling main body and achieving comprehensive fine adjustment.
