Description

Technical Field

[0001] The utility model relates to a support shoe and a TBM host machine and a TBM using the support shoe, belonging to the technical field of excavation equipment. Background Art

[0002] The full-face tunnel boring machine (TBM) is a large-scale tunnel construction equipment that integrates multiple systems such as machinery, electricity, fluid, light, and gas. The main beam of the TBM is equipped with a support shoe, which is used to hold the tunnel wall tightly to keep the relative position with the tunnel wall unchanged, and then cooperate with the extension of the propulsion cylinder to drive the TBM forward. When the TBM passes through the broken zone, due to the collapse of the tunnel wall, it is easy to cause the support shoe to have no support point, and it is impossible to provide propulsion for the main machine by holding the tunnel wall tightly. At this time, it is necessary to reinforce the collapsed area with sleeper stacking or cast-in-place concrete. Among them, cast-in-place concrete requires solidification time, and the TBM cannot be constructed before the concrete is completely solidified; sleeper stacking is to insert sleepers between the support shoe and the tunnel wall, so that the support shoe presses the sleeper to provide propulsion for the main machine. Of course, the sleepers can also be replaced with other reinforcement materials such as sandbags, such as the temporary filling scheme disclosed in the Chinese invention patent application with application publication number CN116752995A.

[0003] However, in actual operation, since there is no support at the bottom of the collapse zone and the tightening surface of the support shoe body is an arc surface, there is no support point for reinforcement materials such as sleepers or sandbags when they are stacked. On-site workers need to constantly adjust the posture of the reinforcement materials to achieve the final stacking of the reinforcement materials. This process has high labor intensity and a long stacking time, and cannot meet the construction requirements of TBM to quickly pass through the broken zone. Utility Model Content

[0039] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0040] In view of the technical problems existing in the prior art, the basic technical concept of the utility model is to install a detachable support member on the support shoe body, and the support member has a support portion cantilevered outside the support surface, which can support the reinforcement material filled between the support surface and the hole wall, and provide a temporary support point for the stacking of the reinforcement material, which is convenient for the stacking operation and reduces the workload of manual continuous adjustment of the posture of the reinforcement material, thereby reducing the labor intensity of the manual labor, shortening the stacking time, and reducing the time for the TBM to pass through the crushing zone. At the same time, after the support member is removed, it does not affect the basic function of the support shoe body to normally support the hole wall.

[0041] Embodiment 1 of the support shoe of the utility model:

[0042] like Figure 1 and Figure 2 As shown, the gripper includes a gripper body 1, and the outer side of the gripper body 1 has a tightening surface. Specifically, the gripper body 1 includes an arc-shaped plate 11 and an inner support 12 fixed in the concave structure of the arc-shaped plate 11, the outer wall surface of the arc-shaped plate 11 constitutes the tightening surface, the inner support 12 is fixedly connected to the inner wall surface of the arc-shaped plate 11, and the inner support 12 is arranged vertically, and its longitudinal section is in the shape of a minor arc.

[0043] The gripper body 1 is provided with a detachable connection structure that does not protrude from the tightening surface. The gripper also includes a support member that is installed on the detachable connection structure when in use and removed when not in use. When the support member is installed on the detachable connection structure, it has a support portion that overhangs outside the tightening surface to support the reinforcement material filled between the tightening surface and the hole wall. Figure 3 As shown, the reinforcement material in this embodiment is a sleeper 3, and the support part provides a support point for the stacking of the sleepers 3, which can reduce the workload of manually adjusting the posture of the sleepers 3, thereby reducing the labor intensity, shortening the stacking time, and reducing the time for the TBM to pass through the broken zone. Among them, the support member can be removed when not in use, and the detachable connection structure does not protrude from the tightening surface of the support shoe body 1, so that in a normal area without landslides, the function of the support shoe to tighten the cave wall normally can be guaranteed.

[0044] In this embodiment, the support member has a mounting portion for mounting on the detachable connection structure, such as Figure 1 and Figure 2As shown, the detachable connection structure is a mounting hole 13 that matches the shape of the mounting part. The mounting hole is used as the detachable connection structure to facilitate processing and manufacturing. Specifically, the mounting hole 13 is a through hole that penetrates the support shoe body 1, and penetrates the support shoe body 1 horizontally. This is not only convenient for processing, but also helps to maintain the horizontal posture of the support part, thereby facilitating the support reinforcement material. At the same time, when debris enters the mounting hole 13, it is also convenient to clean it. In addition, since the wall thickness of the arc plate 11 is limited, in order to ensure the installation effect of the support member, a protrusion 14 is convexly provided on the inner wall surface of the arc plate 11 that is away from the tightening surface, and the mounting hole 13 is arranged on the protrusion 14, which is equivalent to extending the length of the mounting hole 13.

[0045] Furthermore, the mounting hole 13 is a smooth hole. When in use, the mounting portion of the support is inserted into the mounting hole 13. There is an insertion gap between the mounting portion and the mounting hole 13. This makes installation and disassembly more convenient, which can shorten the assembly and disassembly time of the support, thereby shortening the time for the TBM to pass through the crushing zone. Furthermore, the mounting hole 13 is a round hole, which is convenient for processing and manufacturing. At the same time, the above-mentioned support member is a support rod 2, and the support rod 2 is a round rod as a whole, which is convenient for configuration. At the construction site, for the convenience of obtaining materials, a steel bar can be used as a support rod. The support rod 2 is a straight rod, which can be easily inserted into the mounting hole 13 from the inside or the outside of the support shoe body 1. At the same time, when the end face of the support portion of the support rod 2 hits the hole wall, it can also retract automatically to prevent the support rod 2 from being bent.

[0046] like Figure 1 and Figure 2 As shown, there are more than two protrusions 14 spaced apart along the front-to-back width direction of the support shoe body 1, that is, there are more than two mounting holes 13 spaced apart along the front-to-back width direction of the support shoe body 1. In the present embodiment, there are four protrusions 14 located in the same front-to-back direction, two of which are located on the front side of the inner support 12, and the other two are located on the rear side of the inner support 12. In this way, a plurality of support rods 2 can be inserted, and the plurality of support rods 2 together form a temporary support platform, which is convenient for supporting the long sleepers.

[0047] At the same time, at least two groups of protrusions 14 are arranged at intervals along the circumference of the tightening surface, that is, at least two groups of mounting holes 13 are arranged at intervals along the circumference of the tightening surface. As mentioned above, the mounting holes 13 in each group are arranged at intervals along the front-to-back direction. In this embodiment, there are three groups of mounting holes 13, and the top group of mounting holes 13 is located in the middle of the circumference of the support shoe body 1. In this way, the support rod 2 installed has three heights, so that according to the actual situation, if the collapse area extends to the bottom of the tunnel, the support rod 2 can be inserted into the bottom mounting hole 13. Figure 3 If the subsidence area does not extend to the bottom of the tunnel, the middle group of mounting holes 13 or the top group of mounting holes 13 are selected to insert the support rods 2 according to the position of the bottom of the subsidence area.

[0048] When the support shoe of the utility model is used, Figure 3 As shown, after the support shoe enters the collapse zone, the support rod 2 is inserted into the appropriate installation hole 13 according to the specific conditions of the collapse zone to form a temporary support platform, and then the sleepers 3 are piled on the support platform, and then the support shoe is controlled to move toward the cave wall to press the sleepers 3, thereby tightening the cave wall and providing propulsion for the main machine, so that the TBM passes through the broken collapse zone. The utility model can realize the rapid stacking of reinforcement materials, thereby realizing the rapid passage of the TBM through the broken zone, has a simple structure, is easy to operate, can reduce the labor intensity of personnel, and improve the construction efficiency of the TBM.

[0049] In other embodiments of the gripper: the reinforcement material can also be a sandbag.

[0050] In other embodiments of the support shoe: a steel pipe can also be used as the support rod, that is, the support rod is a hollow rod.

[0051] In other embodiments of the support shoe: the mounting hole may also be a square hole, in which case the support rod is a square rod adapted thereto; in other embodiments, whether the mounting hole is a square hole or a round hole, the support rod may not be a uniform cross-sectional structure, for example, the support rod is a stepped rod, the cross-sectional dimension of the insertion portion inserted into the mounting hole is small, while the cross-sectional dimension of the support portion for supporting the reinforcement material is large, and even the insertion portion may be rod-shaped, while the support portion may be plate-shaped.

[0052] In other embodiments of the support shoe: the mounting hole can also be a long hole extending in the front-to-back direction. In this case, the support member is a plug-in plate inserted into the mounting hole, and in this case, only one mounting hole can be set in the same front-to-back direction, that is, one plug-in plate is inserted. Of course, more than two mounting holes can also be set, and the reinforcement material can be jointly supported by multiple plug-ins.

[0053] In other embodiments of the support shoe: no matter what form the mounting hole is, the protrusion may not be set on the inner wall surface of the support shoe body facing away from the tightening surface, and the mounting hole may be directly set on the arc plate, or in other embodiments, if the support shoe body is a box-type structure, including inner wall plates and outer wall plates arranged with an inner and outer spacing, the surface of the outer wall plate constitutes the tightening surface, and the mounting hole passes through the inner wall plate and the outer wall plate. Of course, a sleeve can also be clamped between the inner wall plate and the outer wall plate, and the support member passes through the inner hole of the sleeve while passing through the mounting holes on the inner wall plate and the outer wall plate.

[0054] In other embodiments of the support shoe: when the mounting hole is a through hole, the mounting hole may not be a bare hole, for example, the mounting hole is a threaded hole, in which case the mounting portion of the support rod is a screw, or the entire support rod is a screw, and the support rod is threadedly connected to the mounting hole. In this case, the length of the support portion of the support rod cantilevered outside the tightening surface can be adjusted. It should be noted that when placing and tightening the reinforcement material, the end face of the support rod should be avoided from contacting the hole wall.

[0055] In other embodiments of the support shoe: when the mounting hole is a through hole, the mounting hole may not pass through the support shoe body horizontally, but may have a certain inclination, so that the support portion may be slightly inclined upward. At this time, if the mounting hole is specifically a light hole, when the reinforcement material is placed, the support member and the mounting hole are relatively stuck, which can also maintain the stability of the reinforcement material.

[0056] In other embodiments of the support shoe: when the length of the mounting hole is sufficient to meet the installation requirements of the support member, the mounting hole can also be a blind hole. Of course, the opening of the blind hole needs to be set outward, and according to the specific form of the support member, the blind hole can be a long hole, a round hole or a square hole. When the blind hole is a round hole, it can also be a smooth hole or a threaded hole.

[0057] In other embodiments of the support shoe: the detachable connection structure may not be a mounting hole, for example, a groove is provided on the support surface of the support shoe body, a stud is welded on the bottom wall of the groove, the stud constitutes a detachable connection structure, and the stud does not protrude from the support surface. In this case, the support member may be in various forms, such as a support plate or a support rod, and a connecting plate is provided at the end of the support member, and a through hole is provided on the connecting plate for the stud to pass through. The stud passes through the through hole on the connecting plate and is connected to the nut to fix the support member. Of course, to ensure the fixing effect, more than two studs may be provided in one groove, and more than two corresponding through holes are also provided. Among them, when the support member is a support plate, if one support plate is sufficient to support the reinforcement material, it is not necessary to set more than two grooves and corresponding studs at intervals in the front and rear width directions of the support shoe body.

[0058] In other embodiments of the gripper shoe: no matter what form the detachable connection structure is, only two detachable connection structures may be provided in the front and rear width direction of the gripper shoe body, and of course three, five or more detachable connection structures may also be provided.

[0059] In other embodiments of the support shoe: no matter what form the detachable connecting structure is, only two groups of detachable connecting structures can be set in the circumferential direction of the tightening surface, of course, four groups or more can be set, and of course only one group can be set, and no matter how many groups are set, each group can only include one or more than two detachable connecting structures.

[0060] The embodiment of the TBM main machine in the utility model is as follows: the TBM main machine comprises a main beam and a gripping shoe installed on the main beam, and the specific structure of the gripping shoe is the same as the gripping shoe in the above embodiment, which will not be repeated here.
