Description

Technical Field

[0001] This utility model relates to the field of TMB tunnel construction technology, and in particular to a forced correction device for a TBM continuous belt conveyor and a TBM continuous belt conveyor. Background Technology

[0002] Continuous conveyor belts are currently one of the better muck removal methods in TBM tunnel construction. However, during the operation of continuous conveyor belts, due to untimely correction, muck gushing and deviation are common, posing risks to the safety of personnel inside the tunnel and adding extra procedures to subsequent cleanup work.

[0003] To solve the above problems, those skilled in the art generally install a correction roller. Patent (publication number: CN218370113U) discloses a device for preventing belt misalignment and falling off in a TBM continuous belt conveyor. The device includes an idler bracket and a correction roller. The lower end of the idler bracket is fixedly connected to a crossbeam of the TBM continuous belt conveyor support. The inner side wall of the idler bracket is fixedly connected to a buckle. The correction roller is fixed to the idler bracket by the two buckles above and below. This utility model solves the problems of rock debris falling off and belt overturning and falling off by cooperating with the idler bracket, correction roller, TBM continuous belt conveyor support crossbeam and buckles, thus reducing the labor intensity of operators.

[0004] However, during construction, one part of the conveyor belt has more slag and is heavier, resulting in greater lateral pressure on the straightening wheel. On the other hand, the other part of the conveyor belt has less slag and is lighter, resulting in less lateral pressure on the straightening wheel. This causes the pressure on the straightening wheel to fluctuate, making it prone to damage and resulting in a shorter lifespan. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, where the pressure on the straightening wheel of a TBM continuous belt conveyor varies, leading to easy damage and a short lifespan. This invention provides a forced straightening device for a TBM continuous belt conveyor and a TBM continuous belt conveyor.

[0006] In a first aspect, this utility model provides a forced belt alignment device for a TBM continuous belt, comprising:

[0007] A gantry frame with spaced-out columns and a crossbeam connecting the upper parts of adjacent columns;

[0008] The correction structure includes a first rod, which is rotatably engaged with a correction wheel. The lower end of the first rod can slide vertically with the column, and the upper end of the first rod can slide laterally with the crossbeam.

[0009] A drive mechanism is connected to the upper end of the first rod. The drive mechanism can provide a restoring force after the upper end of the first rod slides laterally against the crossbeam, and can also provide a restoring force after the lower end of the first rod slides vertically relative to the column.

[0010] This application describes a forced alignment device for a continuous TBM belt. The alignment wheel is rotatably mounted on a first rod, which is installed on a gantry. When the lateral pressure on the alignment wheel is significant, the upper end of the first rod slides laterally outward along the crossbeam, and the lower end slides vertically downward relative to the column, causing the alignment wheel to move outward. Simultaneously, the vertical tilt angle of the alignment wheel decreases, thus reducing the force on the alignment wheel. Subsequently, the drive mechanism provides a restoring force after the upper end of the first rod slides laterally against the crossbeam, and also provides a restoring force to the first rod. The restoring force after the lower end slides vertically relative to the column results in the following: when the lateral pressure on the straightening wheel decreases, the drive mechanism drives the upper end of the first rod to slide laterally inward along the crossbeam, and the lower end of the first rod slides vertically upward relative to the column, so that the position of the straightening wheel tends to be restored, so as to ensure that it can still play the role of correcting the slag and soil when the force is small. In the above process, the straightening wheel on the TBM continuous belt forced straightening device described in this application can adjust its position according to the magnitude of the lateral pressure, so as to reduce the fatigue stress of the straightening wheel and the first rod, thereby increasing the service life of the straightening wheel.

[0011] Preferably, the column is provided with a first slot, the lower end of the first rod is connected to a first support, the first support is located in the first slot, and the first support is in vertical reciprocating sliding engagement with the column.

[0012] Preferably, the first support is provided with first protrusions on both sides, and the first slot is provided with first strip holes vertically on the sidewalls on both sides of the first slot, and the first protrusions slide in cooperation with the corresponding first strip holes.

[0013] Preferably, the crossbeam is provided with a second slot, the upper end of the first rod is connected to a second support, the second support is located in the second slot, and the second support is in lateral reciprocating sliding engagement with the crossbeam.

[0014] Preferably, the second support is provided with second protrusions on both sides, and second strip holes are provided laterally on the sidewalls on both sides of the second slot, and the second protrusions slide in cooperation with the corresponding second strip holes.

[0015] Preferably, the drive mechanism is located within the second slot.

[0016] Preferably, a connecting member is hinged to the second support, and the connecting member is connected to the drive mechanism. The connecting member is vertically swaying relative to the second support. This is to prevent the top of the first rod from rotating and causing excessive force on the drive mechanism when the angle changes.

[0017] Furthermore, when the second support moves laterally, it can drive the first support to move vertically.

[0018] Preferably, the driving mechanism includes a base and a threaded rod. The base has a through hole, the threaded rod passes through the through hole, and the threaded rod is threadedly connected to a first nut and a second nut. The base is located between the first nut and the second nut, and a spring is connected between the threaded rod and the second support. The spring is arranged along the length of the threaded rod.

[0019] The TBM continuous belt forced alignment device described in this application, when encountering significant lateral pressure on the alignment wheel, causes the upper end of the first rod to slide laterally outward along the crossbeam, driving the lower end of the first rod to slide vertically downward relative to the column. At this time, the second support drives the spring to tension, causing the alignment wheel to move outward. Simultaneously, the vertical tilt angle of the alignment wheel decreases, thereby reducing the force on the alignment wheel. Subsequently, because the spring provides the restoring force after the upper end of the first rod slides laterally against the crossbeam, when the lateral pressure on the alignment wheel decreases, the spring drives the second support to slide laterally inward along the crossbeam. Moreover, the second support, through the first rod, drives the first support to slide vertically upward relative to the column, causing the alignment wheel to tend to return to its original position. This ensures that it can still perform the function of correcting the alignment of the slag even when the force is small. In the above process, the alignment wheel can adjust its position according to the magnitude of the lateral pressure, thereby reducing the fatigue stress of the alignment wheel and the first rod and increasing the service life of the alignment wheel.

[0020] In a second aspect, this utility model provides a TMB tunnel continuous belt mechanism, including a base, a belt, and a TBM continuous belt forced correction device as described in this application, wherein the gantry is connected to the base, and the belt is disposed between two columns.

[0021] The TMB tunnel continuous belt conveyor mechanism described in this application includes a forced correction device for the TMB continuous belt conveyor. A correction wheel is rotatably mounted on a first rod, which is installed on a gantry. When the lateral pressure on the correction wheel is significant, the upper end of the first rod slides laterally outward along the crossbeam, and the lower end slides vertically downward relative to the column, causing the correction wheel to move outward. Simultaneously, the vertical tilt angle of the correction wheel decreases, thus reducing the force on the correction wheel. Subsequently, the drive mechanism provides a restoring force after the upper end of the first rod slides laterally against the crossbeam. Furthermore, it can provide a restoring force after the lower end of the first rod slides vertically relative to the column. When the lateral pressure on the correction wheel decreases, the drive mechanism drives the upper end of the first rod to slide laterally inward along the crossbeam, and the lower end of the first rod slides vertically upward relative to the column, so that the position of the correction wheel tends to be restored, so as to ensure that it can still play the role of correcting the deviation of the slag when the force is small. In the above process, the correction wheel on the TBM continuous belt forced correction device described in this application can adjust its position according to the magnitude of the lateral pressure, so as to reduce the fatigue stress of the correction wheel and the first rod, thereby increasing the service life of the correction wheel.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This application describes a forced alignment device for a continuous TBM belt. The alignment wheel is rotatably mounted on a first rod, which is installed on a gantry. When the lateral pressure on the alignment wheel is significant, the upper end of the first rod slides laterally outward along the crossbeam, and the lower end slides vertically downward relative to the column, causing the alignment wheel to move outward. Simultaneously, the vertical tilt angle of the alignment wheel decreases, thus reducing the force on the alignment wheel. Subsequently, the drive mechanism provides a restoring force after the upper end of the first rod slides laterally against the crossbeam, and also provides a restoring force to the first rod. The restoring force after the lower end slides vertically relative to the column results in the following: when the lateral pressure on the straightening wheel decreases, the drive mechanism drives the upper end of the first rod to slide laterally inward along the crossbeam, and the lower end of the first rod slides vertically upward relative to the column, so that the position of the straightening wheel tends to be restored, so as to ensure that it can still play the role of correcting the slag and soil when the force is small. In the above process, the straightening wheel on the TBM continuous belt forced straightening device described in this application can adjust its position according to the magnitude of the lateral pressure, so as to reduce the fatigue stress of the straightening wheel and the first rod, thereby increasing the service life of the straightening wheel.

[0038] Example 1

[0039] like Figure 1-5 As shown in this embodiment, a forced belt alignment device for a TBM continuous belt includes:

[0040] The gantry 1 has spaced columns 12, and a crossbeam 11 is connected between the upper parts of adjacent columns 12.

[0041] The correction structure 2 includes a first rod 21, which is rotatably engaged with a correction wheel 22. The lower end of the first rod 21 can slide vertically with the column 12, and the upper end of the first rod 21 can slide laterally with the crossbeam 11.

[0042] The drive mechanism 3 is connected to the upper end of the first rod 21. The drive mechanism 3 can provide the restoring force after the upper end of the first rod 21 slides laterally with the crossbeam 11, and can also provide the restoring force after the lower end of the first rod 21 slides vertically relative to the column 12.

[0043] The TBM continuous belt forced alignment device described in this application has an alignment wheel 22 rotatably mounted on a first rod 21. The first rod 21 is installed on a gantry 1. When the lateral pressure on the alignment wheel 22 is large, the upper end of the first rod 21 slides laterally outward along the crossbeam 11, and the lower end of the first rod 21 slides vertically downward relative to the column 12, causing the alignment wheel 22 to move outward. At the same time, the corresponding vertical tilt angle of the alignment wheel 22 decreases, thereby reducing the force on the alignment wheel 22. Subsequently, the drive mechanism 3 can provide the restoring force after the upper end of the first rod 21 slides laterally against the crossbeam 11, and can also provide the force for the first rod 22 to move outward. The restoring force of the lower end of the first rod 21 after sliding vertically relative to the column 12 results in the following: when the lateral pressure on the straightening wheel 22 decreases, the drive mechanism 3 drives the upper end of the first rod 21 to slide laterally inward along the crossbeam 11, and the lower end of the first rod 21 slides vertically upward relative to the column 12, so that the position of the straightening wheel 22 tends to be restored, so as to ensure that it can still play the role of correcting the deviation of the slag when the force is small. In the above process, the straightening wheel 22 on the TBM continuous belt forced deviation correction device described in this application can adjust its position according to the magnitude of the lateral pressure, so as to reduce the fatigue stress of the straightening wheel 22 and the first rod 21, thereby increasing the service life of the straightening wheel 22.

[0044] In one or more embodiments, the column 12 is provided with a first slot 13, the lower end of the first rod 21 is connected to a first support 23, the first support 23 is located in the first slot 13, and the first support 23 is in vertical reciprocating sliding engagement with the column 12.

[0045] In one or more embodiments, first protrusions 24 are provided on both sides of the first support 23, and first strip holes 14 are vertically provided on the sidewalls on both sides of the first slot 13, and the first protrusions 24 slide in cooperation with the corresponding first strip holes 14.

[0046] In one or more embodiments, the crossbeam 11 is provided with a second slot 15, the upper end of the first rod 21 is connected to a second support 25, the second support 25 is located in the second slot 15, and the second support 25 is in transverse reciprocating sliding engagement with the crossbeam 11.

[0047] In one or more embodiments, the second support 25 is provided with second protrusions 26 on both sides, and the second slot 15 is provided with second strip holes 16 laterally on the sidewalls on both sides, and the second protrusions 26 are slidably engaged with the corresponding second strip holes 16.

[0048] In one or more embodiments, the drive mechanism 3 is located within the second slot 15.

[0049] In one or more embodiments, a connector 27 is hinged to the second support 25, and the connector 27 is connected to the drive mechanism 3. The connector 27 is vertically swaying relative to the second support 25. This is to prevent the top of the first rod 21 from rotating and causing excessive force on the drive mechanism 3 when the angle changes.

[0050] Furthermore, when the second support 25 moves laterally, it can drive the first support 23 to move vertically.

[0051] like Figure 5 As shown, in one or more embodiments, the drive mechanism 3 includes a base 31 and a threaded rod 32. The base 31 is provided with a through hole 33, and the threaded rod 32 passes through the through hole 33. The threaded rod 32 is threadedly connected to a first nut 34 and a second nut 35. The base 31 is located between the first nut 34 and the second nut 35. A spring 36 is connected between the threaded rod 32 and the second support 25. The spring 36 is arranged along the length direction of the threaded rod 32.

[0052] The TBM continuous belt forced alignment device described in this application, when encountering significant lateral pressure on the alignment wheel 22, causes the upper end of the first rod 21 to slide laterally outward along the crossbeam 11, driving the lower end of the first rod 21 to slide vertically downward relative to the column 12. At this time, the second support 25 drives the spring 36 to tension, causing the alignment wheel 22 to move outward. Simultaneously, the corresponding vertical tilt angle of the alignment wheel 22 decreases, thereby reducing the force on the alignment wheel 22. Subsequently, due to the spring 36 providing support for the upper end of the first rod 21 to slide laterally against the crossbeam 11... The spring 36 drives the second support 25 to slide laterally inward along the crossbeam 11 when the lateral pressure on the straightening wheel 22 decreases. Moreover, the second support 25 drives the first support 23 to slide vertically upward relative to the column 12 through the first rod 21, so that the position of the straightening wheel 22 tends to be restored, so as to ensure that it can still play the role of correcting the slag when the force is small. In the above process, the straightening wheel 22 can adjust its position according to the magnitude of the lateral pressure it receives, so as to reduce the fatigue stress of the straightening wheel 22 and the first rod 21, thereby increasing the service life of the straightening wheel 22.

[0053] In one or more embodiments, the column 12 and the beam 11 are integrally formed.

[0054] In one or more embodiments, the correction wheel 22 and the first rod 21 are rotated together via bearings.

[0055] In one or more embodiments, to ensure smooth sliding, a counterweight is installed at the bottom of the first support 23 to provide additional downward gravity to the correction structure 2.

[0056] Example 2

[0057] like Figure 6 As shown in the figure, the TMB tunnel continuous belt mechanism described in this embodiment includes a base 4 and a belt 5. The gantry 1 is connected to the base 4, and the belt 5 is disposed between two columns 12.

[0058] The TMB tunnel continuous belt mechanism described in this application includes a forced correction device for a TBM continuous belt. A correction wheel 22 is rotatably mounted on a first rod 21, which is installed on a gantry 1. When the lateral pressure on the correction wheel 22 is significant, the upper end of the first rod 21 slides laterally outward along the crossbeam 11, and the lower end of the first rod 21 slides vertically downward relative to the column 12, causing the correction wheel 22 to move outward. Simultaneously, the corresponding vertical tilt angle of the correction wheel 22 decreases, thereby reducing the force on the correction wheel 22. Subsequently, the drive mechanism 3 provides recovery after the upper end of the first rod 21 slides laterally against the crossbeam 11. The drive mechanism 3 provides a force and can provide a restoring force after the lower end of the first rod 21 slides vertically relative to the column 12. When the lateral pressure on the correction wheel 22 decreases, the drive mechanism 3 drives the upper end of the first rod 21 to slide laterally inward along the crossbeam 11, and the lower end of the first rod 21 slides vertically upward relative to the column 12, so that the position of the correction wheel 22 tends to be restored, so as to ensure that it can still play the role of correcting the slag when the force is small. In the above process, the correction wheel 22 on the TBM continuous belt forced correction device described in this application can adjust its position according to the magnitude of the lateral pressure, so as to reduce the fatigue stress of the correction wheel 22 and the first rod 21, thereby increasing the service life of the correction wheel 22.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
