At this time, the outer end of the reset component will smoothly pull the upper and lower ends of the correcting mechanism to reset in opposite directions, so as to carry out subsequent correction processing. At this time, the inner end of the linkage component will extend out to support the inner ends of both sides of the upper and lower parts of the correcting mechanism, thereby improving stability.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1 to 11As shown, the present invention provides an automatic deviation correction device for long-distance jacking of a tunnel using a jacking method, comprising a tunneling jacking machine 1 and a reinforced concrete pipe 2, and further comprising: an axis monitoring device 4, the axis monitoring device 4 being arranged at the top of one side of the inner cavity of the tunneling jacking machine 1; a mounting ring 6, the mounting ring 6 being arranged on the inner side of the inner wall of the tunneling jacking machine 1 and the reinforced concrete pipe 2, and having a deviation correction mechanism 8 arranged on the inner side; a hydraulic cylinder 7, the hydraulic cylinder 7 being hinged to the inner side of the mounting ring 6; wherein the deviation correction mechanism 8 includes a mounting frame 801 arranged inside the mounting ring 6 on one side. A gap is left between the outer end of the other side of the mounting frame 801 and the mounting ring 6 inside the tunneling pipe jacking machine 1, which can prevent the tunneling pipe jacking machine 1 and the mounting ring 6 from pushing one side of the mounting frame 801 to be squeezed and collided when the tunneling pipe jacking machine 1 and the mounting ring 6 are offset as a whole. A correction rod 802 is provided on the inner side of the mounting ring 6 inside the tunneling pipe jacking machine 1, and auxiliary correction pressing plates 803 are provided on the upper and lower ends of the inner side of the mounting frame 801. A connecting block 804 is provided in the middle of one side of the auxiliary correction pressing plate 803, and a driving frame 805 located between the connecting blocks 804 is movably installed inside one side of the mounting frame 801.

[0037] When the axis monitoring device 4 monitors that the tunneling pipe jacking machine 1, the mounting ring 6 and the correcting rod 802 are offset as a whole, the hydraulic cylinder 7 can be started to drive the tunneling pipe jacking machine 1, the mounting ring 6 and the correcting rod 802 to move to one side as a whole, which will cause one side of the correcting rod 802 to be flattened by the inner side of one end of the mounting frame 801, and the driving frame 805 will be pushed through the connecting block 804 to drive the two auxiliary correcting pressing plates 803 to press and flatten the upper and lower parts of the correcting rod 802, thereby realizing automatic correction of the correcting rod 802 and the tunneling pipe jacking machine 1 as a whole.

[0038] like Figure 11 As shown, the inner side of the connecting block 804 is inclined, and the outer side of the driving frame 805 adopts a bevel design, and the inner bevel of the connecting block 804 and the bevel of the driving frame 805 are completely fitted together.

[0039] The above solution is adopted: by providing a driving frame 805, when one side of the correction rod 802 contacts and flattens the inner surface of one side of the mounting frame 801, it will simultaneously push the entire driving frame 805 to move to one side, so that the outer inclined surface of the driving frame 805 is along the inner inclined surface of the connecting block 804, and will drive the connecting block 804 and the auxiliary correction pressing plate 803 to move smoothly towards each other as a whole.

[0040] like Figure 3 As shown, a metal sealing ring 5 is provided on one side surface of the reinforced concrete pipe 2 and is located on the inner side of one end of the tunneling pipe jacking machine 1.

[0041] By adopting the above solution, the connection between the tunneling pipe jacking machine 1 and the reinforced concrete pipe 2 can be preliminarily sealed through the design of the metal sealing ring 5 .

[0042] like Figure 1 and Figure 2 As shown, a tunneling mechanism 3 is provided at the other end of the tunneling pipe jacking machine 1 .

[0043] With the above solution, by providing the excavation mechanism 3, the operator can start the excavation mechanism 3 to make the entire excavation pipe jacking machine 1 perform excavation operations inside the underground soil layer, thereby achieving the purpose of pipe jacking.

[0044] like Figure 3 As shown, an auxiliary sealing assembly 9 is provided on the inner side of the mounting ring 6 and located on the outer side of the hydraulic cylinder 7. The auxiliary sealing assembly 9 includes a fixing ring 901, a first sealing ring 902, a second sealing ring 903 and a bellows 904;

[0045] The fixing ring 901 is arranged on one side of the mounting ring 6 inside the reinforced concrete pipe 2, the first sealing ring 902 is slidably connected to the inside of the fixing ring 901, the second sealing ring 903 is spherically sleeved on one side of the first sealing ring 902, and the other end of the second sealing ring 903 is fixedly connected to one side of the mounting ring 6 inside the tunneling jacking machine 1, and the bellows 904 is arranged on the outside of the connection between the first sealing ring 902 and the second sealing ring 903.

[0046] The above solution is adopted: by providing a bellows 904, since the connection between the first sealing ring 902 and the second sealing ring 903 is a spherical socket, a gap will be left, and through the design of the bellows 904, the gap can be blocked and sealed, thereby improving the sealing effect of the first sealing ring 902 and the second sealing ring 903 on the outside of the mounting ring 6.

[0047] like Figure 3 and Figure 6 As shown, one end of the first sealing ring 902 is elastically connected to the inner wall of the fixing ring 901 through the buffer spring 10.

[0048] The above solution is adopted: by providing a buffer spring 10, when the hydraulic cylinder 7 drives the tunneling jacking machine 1, the mounting ring 6, the second sealing ring 903 and the first sealing ring 902 to move as a whole at the same time, the buffer spring 10 will be stretched, and when the second sealing ring 903 and then the first sealing ring 902 are driven to reset as a whole, the reset force can be buffered by the elastic force of the buffer spring 10, thereby avoiding damage to the fixing ring 901 caused by resetting too quickly.

[0049] like Figure 5 As shown, a reset assembly 11 is provided on the other side of the mounting frame 801. The reset assembly 11 includes a limit rod 1101, a movable plate 1102 and a reset connecting arm 1103.

[0050] The limiting rod 1101 is fixedly installed inside the other side of the mounting frame 801 and is located on the inner side of the auxiliary correction pressing plate 803. The movable plate 1102 is movably installed inside the other side of the mounting frame 801 and is located on the outer side of the limiting rod 1101. The reset connecting arm 1103 is hinged between the top of the movable plate 1102 and the other side of the auxiliary correction pressing plate 803.

[0051] The above solution is adopted: by providing a reset connecting arm 1103, when the movable plate 1102 as a whole moves to one side, the reset connecting arm 1103 will deflect and push the two auxiliary deviation-correcting pressing plates 803 to move away from each other and reset.

[0052] like Figure 5 As shown, the surface of the limiting rod 1101 is slidably connected to the inner wall of the other end of the auxiliary deviation-correcting pressing plate 803.

[0053] By adopting the above solution, when the auxiliary deflection-correcting pressing plate 803 moves up and down as a whole, the other end can move vertically up and down along the surface of the limiting rod 1101 , which plays a good limiting role in the movement of the auxiliary deflection-correcting pressing plate 803 .

[0054] like Figure 5 、 Figure 8 、 Figure 9 and Figure 11 As shown, a linkage assembly 12 is provided between the middle portion of the outer side of the mounting ring 6 and the middle portion of the mounting frame 801. The linkage assembly 12 includes a hydraulic chamber 1201, a first hydraulic piston rod 1202, a hydraulic cylinder 1203 and a second hydraulic piston rod 1204.

[0055] The hydraulic chamber 1201 is opened on both sides of the middle part of the mounting ring 6 and is close to the buffer spring 10. The first hydraulic piston rod 1202 is movably installed in the inner cavity of the hydraulic chamber 1201. The hydraulic cylinder 1203 is arranged in the middle part of the outer side of one end of the mounting frame 801. The second hydraulic piston rod 1204 is movably installed in the inner cavity of the hydraulic cylinder 1203. One end of the second hydraulic piston rod 1204 is fixedly connected to the middle part of one side of the movable plate 1102. The hydraulic cylinder 1203 is connected to the hydraulic chamber 1201 through the oil groove 1205.

[0056] The above solution is adopted: by providing a second hydraulic piston rod 1204, when the first sealing ring 902 moves and resets as a whole, the middle part of the first sealing ring 902 will push the first hydraulic piston rod 1202 to retract into the inner cavity of the hydraulic chamber 1201, so that the inner cavity of the hydraulic chamber 1201 becomes larger and generates negative pressure, and then the hydraulic oil in the inner cavity of the hydraulic cylinder 1203 is drawn away through the oil groove 1205, so that the second hydraulic piston rod 1204 is smoothly driven to drive the movable plate 1102 as a whole to move to one side.

[0057] like Figure 10As shown, the other end of the mounting frame 801 is provided with a supporting assembly 13 located inside both ends of the auxiliary deflection-correcting pressing plate 803. The supporting assembly 13 includes a telescopic rod 1301, a power spring 1302 and a supporting block 1303.

[0058] The telescopic rod 1301 is fixedly installed inside the other side of the mounting frame 801 and is located at both ends of the inner side of the auxiliary correction pressing plate 803. The power spring 1302 is set at the inner end of the telescopic rod 1301, and the power spring 1302 is elastically connected to the telescopic rod 1301 through the supporting block 1303.

[0059] The above solution is adopted: by providing a support block 1303, when the auxiliary correction pressing plate 803 moves back to the outside of the power spring 1302, the elastic force of the support block 1303 will be released, and the power spring 1302 will be pushed inward, which can push the inner side of the auxiliary correction pressing plate 803 after moving back to back for auxiliary support.

[0060] The working principle and use process of the present invention:

[0061] First, when the operator monitors in real time through the axis monitoring device 4 that the axes of the tunneling pipe jacking machine 1 and the reinforced concrete pipe 2 are offset, that is, the tunneling pipe jacking machine 1 is offset relative to the reinforced concrete pipe 2, the hydraulic cylinder 7 can be started to drive the tunneling pipe jacking machine 1, the mounting ring 6 and the correction rod 802 to move to one side as a whole. At this time, the offset of the tunneling pipe jacking machine 1 will drive the second sealing ring 903 to deviate at the same time, and the design of the bellows 904 can maintain the sealing effect of the first sealing ring 902 and the second sealing ring 903. After that, the overall movement and extension of the tunneling pipe jacking machine 1 will drive the first sealing ring 902 and the second sealing ring 903 to move and extend as a whole, maintaining the seal on the outside between the two mounting rings 6, and blocking and sealing the gap between the tunneling pipe jacking machine 1 and the reinforced concrete pipe 2.

[0062] Then, through the overall movement of the correcting rod 802, one side contacts the inner surface of one side of the mounting frame 801, so that one side is squeezed and flattened, and the driving frame 805 moves to one side as a whole. At this time, the inclined surface on the outside of the driving frame 805 will slide along the inner inclined surface of the connecting block 804, and will squeeze and drive the connecting block 804 and the auxiliary correcting pressing plate 803 to move toward each other as a whole, and the auxiliary correcting pressing plate 803 will squeeze and push the inclined surface of the power spring 1302, so that the power spring 1302 compresses the telescopic rod 1301 in opposite directions at the same time, and finally the auxiliary correcting pressing plate 803 will smoothly press and flatten the upper and lower ends of the correcting rod 802 downward, thereby making the correcting rod 802, the mounting ring 6 and the tunneling jacking machine 1 as a whole accurately and automatically corrected.

[0063] Finally, the operator can start the hydraulic cylinder 7 to drive the overall movement of the tunneling jacking machine 1, the installation ring 6 and the correction rod 802 to reset, and the buffer spring 10 and the first sealing ring 902 are used for buffering during the reset, and the reset of the first sealing ring 902 will cause the other side of the middle to push the first hydraulic piston rod 1202 into the inner cavity of the hydraulic chamber 1201, so that the gap in the inner cavity of one side of the hydraulic chamber 1201 becomes larger, and negative pressure is generated, so that the hydraulic pressure inside the hydraulic cylinder 1203 can be increased through the oil groove 1205. The oil is pumped away, which in turn drives the second hydraulic piston rod 1204 to push the movable plate 1102 to move to one side as a whole, and then causes the reset connecting arm 1103 to deflect and push the two auxiliary correction pressing plates 803 to reset in opposite directions for subsequent correction. By moving the auxiliary correction pressing plate 803 to the outside of the power spring 1302, the elastic force of the support block 1303 will be released, allowing the power spring 1302 to extend, so as to provide auxiliary support to the inner part of the auxiliary correction pressing plate 803 to reinforce its stability.
