Description

TECHNICAL FIELD

[0001] The utility model relates to the field of full face tunneling equipment, especially to a kind of advance drill rig mounting device, advance drill rig system and TBM. BACKGROUND

[0002] TBM (Full Face Hard Rock Tunneling Machine) is mainly used for tunnel excavation under hard rock geological conditions, and its main components include a main machine and a rear supporting system, wherein the main machine includes a shield body, a cutterhead and a main beam installed on the shield body and the like. During construction, the rotation of the cutterhead realizes the extrusion and crushing of the front face, and the steering is realized by the support shoe assembly provided on the main beam. TBM may encounter different geological conditions during operation, and when encountering broken and unstable strata, advance drilling and grouting reinforcement are needed using an advance drill rig; for uncertain geological conditions in front, advance detection is needed using an advance drill rig; for gushing water strata, grouting plugging is needed using an advance drill rig. Therefore, the advance drill rig is one of the important accessories of TBM. Due to the existence of the shield body, the advance drill rig is blocked, so the shield body of the TBM is provided with drilling holes of different angles and different positions, and when the advance drill rig is working, the drill rod is aligned and passes through the corresponding drilling hole to perform related operations.

[0003] A movable advance drilling and grouting integrated machine suitable for TBM is disclosed in Chinese Patent Application No. CN114198027A, published on March 18, 2022, which discloses a mounting device for an advance drill rig in the specification. The mounting device includes a translation slide rail fixedly installed on the main beam of the TBM and a ring-shaped track movably installed on the translation slide rail. The ring-shaped track is provided with a translation driving device, and under the action of the translation driving device, the ring-shaped track moves back and forth along the translation slide rail. A drill rig mounting trolley is arranged on the ring-shaped track, and the drill rig mounting trolley is provided with a trolley driving device. Under the action of the trolley driving device, the drill rig mounting trolley can move back and forth along the ring-shaped track. A drill rig mounting platform is further provided on the drill rig mounting trolley, and the advance drill rig is hinged to the drill rig mounting platform and connected to the drill rig mounting platform through an elevation adjustment cylinder, so that the advance drill rig can perform elevation movement.

[0004] In the above-mentioned patent application, the position of the advance drill rig in the circumferential direction of the tunnel can be adjusted by moving the drill rig mounting trolley along the ring-shaped track, the position of the advance drill rig in the front-back direction can be adjusted by moving the ring-shaped track back and forth along the translation slide rail, and the elevation angle of the advance drill rig can be adjusted by swinging. By matching the position in the circumferential direction of the tunnel, the position in the front-back direction and the elevation angle, the drill rod of the advance drill rig can be aligned with the drilling holes at different positions of the shield body, and the normal operation of the advance drill rig can be ensured.

[0005] However, although the above patent application can realize the loading of the advance drill rig to the TBM, in the actual construction process, the TBM often encounters the situations of turning excavation and uphill and downhill excavation, in which case, the angle of the main beam relative to the shield body will change (from coaxial to having a certain angle of the axis), when located at the preset advance drill rig operation position, the drill rod of the advance drill rig may not be able to align with the corresponding drilling hole, and the related operation work cannot be carried out. In addition, when there are many drilling holes distributed in front and back on the shield body, the annular track needs to move a relatively long distance on the main beam of the TBM to be coaxially aligned with each drilling hole respectively, and the space on the main beam of the TBM is limited, sometimes it cannot meet the demand. Limited by the angle of the drilling hole, the advance drill rig often has a long overhanging length before passing through the drilling hole, which is not conducive to the alignment of the drill rod and the drilling hole, and is also not conducive to the stability of the advance drill rig in the working process.

DETAILED DESCRIPTION

[0054] The features and performances of the utility model are further described in detail in combination with the embodiments.

[0055] In a mechanism, more degrees of freedom mean more flexible movement of the end effector. Therefore, when faced with the problem that the advanced drilling rig 101 cannot align with the drilling hole set on the shield 102 during the TBM turning process in the prior art, the above problem can be overcome by increasing the degrees of freedom of the advanced drilling rig mounting device. This utility model is based on the above inventive concept and proposes a technical solution for the advanced drilling rig mounting device.

[0056] Based on the above inventive concept, the basic scheme of the advanced drilling rig mounting device of this utility model is as follows:

[0057] like Figures 1-6 As shown, the advanced drilling rig mounting device includes a circular track 103 that can move back and forth. In use, the circular track 103 can be mounted on the main beam of the TBM using a linear track 104, and a front and rear drive device 105 (such as a hydraulic cylinder) is provided to drive it to move back and forth along the extension direction of the main beam to adjust its front and rear position in the extension direction of the main beam. Of course, the circular track is installed on the TBM in a ring-like manner. In order to achieve cooperation with the corresponding linear track 104, rollers or sliders can be provided on the inner side of the circular track 103.

[0058] A drilling rig carrying trolley 106 is mounted on the circular track 103. As the name suggests, the drilling rig carrying trolley 106 is a trolley used to carry the drilling rig, specifically the advanced drilling rig 101. The drilling rig carrying trolley 106 can move back and forth along the circular track 103, thereby driving the advanced drilling rig 101 mounted on it to move back and forth. As a typical structure, the drilling rig carrying trolley 106 includes a frame 61. The frame 61 serves two purposes: firstly, it cooperates with the circular track 103 to realize the installation of the drilling rig carrying trolley 106 onto the circular track 103; secondly, it serves as a carrier for other components of the drilling rig carrying trolley 106.

[0059] As a typical structure, the circular track 103 adopts a "toothed track" structure, specifically including a toothed ring 31 in the middle and steel rails 32 located on both sides of the toothed ring. The side of the steel rail 32 near the outer circumference of the toothed ring is provided with an outward flange. An upper clamping wheel 62, a lower clamping wheel 63 and a gear are provided on the frame 61. The upper clamping wheel 62 and the lower clamping wheel 63 cooperate with the outward flange of the steel rail 32 to keep the frame 61 on the circular track 103. The gear cooperates with the toothed ring 31. By configuring a trolley drive device 64 for the gear, the drilling rig carrying the trolley 106 can be driven to move back and forth along the circular track. This reciprocating movement is achieved by the forward and reverse rotation of the trolley drive device 64.

[0060] The drilling machine mounting platform is a lifting platform, which is used for directly mounting the leading drill 101 in use, and the leading drill 101 is driven to reciprocate in the radial direction of the annular track 103, i.e. the radial direction of the tunnel, through the lifting of the lifting platform, so as to adjust the position of the supporting point of the leading drill 101 in the radial direction of the tunnel.

[0061] The drilling machine mounting platform is a lifting platform, which is used for directly mounting the leading drill 101 in use, and the leading drill 101 is driven to reciprocate in the radial direction of the annular track 103, i.e. the radial direction of the tunnel, through the lifting of the lifting platform, so as to adjust the position of the supporting point of the leading drill 101 in the radial direction of the tunnel.

[0062] Through the above structure, in use, the annular track 103 can be driven to move forward and backward along the tunnel axis through the driving of the front and rear driving device 105, i.e. the leading drill 101 can move forward and backward along the tunnel axis; the drilling machine mounting trolley 106 can be driven to move along the circumferential direction of the annular track through the action of the trolley driving device 64, i.e. the leading drill 101 can move along the circumferential direction of the tunnel axis; the leading drill 101 can be lifted along the direction perpendicular to the tunnel axis through the lifting action of the drilling machine mounting platform; the leading drill 101 can be tilted along the tunnel axis through the action of the tilting adjusting structure; and the leading drill 101 can be rotated along the axis perpendicular to the tunnel axis through the corner adjusting structure. The coordination of the above actions can realize the rapid hole alignment of the leading drill, so as to realize the leading drilling and grouting, and improve the efficiency, convenience and reliability of the leading drill.

[0063] Due to the above structure, the moving distance of the annular track 103 can be reduced, and the demand for the moving space can be reduced, so as to adapt to the limited space around the TBM host. Figure 7 As shown in the figure, assuming that the position and angle of a drilling hole on the shield 102 are determined, when the drilling machine mounting platform is in the falling state, if the drill rod 107 is to be directly opposite to the drilling hole, the position of the drilling machine mounting trolley 106 in the tunnel axial direction should be at point A, and when the drilling machine mounting platform is in the rising state, the leading drill 101 will be closer to the shield 102 in the radial direction of the tunnel, at this time, if the drill rod 107 is to be directly opposite to the drilling hole, the position of the drilling machine mounting trolley 106 in the tunnel axial direction only needs to be at point B, compared with point A, point B is closer to the position of the shield 102, therefore, the size of the moving distance of the annular track 103 needs to be smaller, and the length L of the suspended part of the drill rod 107 from the leading drill to the drilling hole will be smaller, which will be more conducive to maintaining the stability of the drilling process.

[0064] On the basis of the above basic scheme, as a preferred embodiment, in order to realize the stable lifting cooperation between the drilling rig loading platform and the frame, a guide column is arranged on one of the frame 61 and the drilling rig loading platform, and a guide sleeve is arranged on the other, the drilling rig loading platform and the frame 61 are guided and cooperated through the guide column and the guide sleeve, and a lifting driving device 108 is arranged between the frame 61 and the drilling rig loading platform. Figures 3-6 In the embodiment shown, the guide sleeve is arranged on the drilling rig loading platform, and the guide column is fixedly arranged on the frame 61. In this embodiment, the guide column adopts a single-column structure, the guide column and the guide sleeve are located at the middle position of the frame 61 in the front-rear direction, and the lifting driving device 108 is arranged at the periphery of the guide column, but those skilled in the art should understand that in some other embodiments, the guide column can also adopt a double-column, triple-column, four-column or the like structure, and the number is not limited, and in this case, the lifting driving device can also be arranged in the space surrounded by the guide columns and arranged in the middle.

[0065] On the basis of the above preferred embodiment, the frame 61 comprises a front apron 611 and a rear apron 612, the front apron 611 and the rear apron 612 are arranged in front of and behind each other, and the space formed between the two can be arranged with the above-mentioned gears, upper clamping wheels 62 and lower clamping wheels 63. In order to ensure the compactness of the structure of the drilling rig loading trolley 106, the lifting driving device 108 is arranged by means of the front apron 611 and the rear apron 612, specifically, corresponding hinged seats are arranged on the lower edges of the front apron 611 and the rear apron 612 respectively, and the lifting driving device 108 is connected to the corresponding hinged seats. Of course, in addition to the hinged structure, the lifting driving device 108 can also be directly fixed on the front and rear aprons by bolts or the like. The lifting driving device 108 can specifically adopt a lifting driving oil cylinder, or a lead screw pushing device, and the like, which will not be described here.

[0066] In a preferred embodiment, the rotation angle adjusting structure comprises a rotation cooperation structure for cooperation with the drilling rig base and a left jack 109 and a right jack 110 for cooperation with the drilling rig base.

[0067] When the drilling rig base is installed on the corresponding bearing surface, it is positioned by the rotation cooperation structure, and then the left jack 109 and the right jack 110 are used to jack up the drilling rig base to make it rotate relative to the bearing surface, thereby realizing the adjustment of the rotation angle. In a preferred embodiment, the left jack 109 and the right jack 110 are arranged opposite to each other, that is, they are coplanar in the front-rear direction. Of course, in some other embodiments, the left jack 109 and the right jack 110 can also be staggered in the front-rear direction. In addition, the rotation angle adjusting structure can also be a gear cooperation structure, for example, a gear is arranged on the bearing body of the drilling rig, and the gear is driven to rotate by the cooperating gear.

[0068] When the rotating fitting structure, the left jackscrew and the right jackscrew are used as the rotation angle adjusting structure, as shown in FIG. Figures 3-4 The rotating fitting structure can be a vertical positioning pin 111 arranged on the drill rig mounting platform, and the drill rig is fixed on the drill rig mounting platform through a fastening bolt, a hole matched with the bolt is arranged as a waist-shaped hole, the hole is loosened during adjustment, and then is fastened and fixed after adjustment.

Figures 3-6 In the embodiment shown in FIG.

[0070] It should be noted that, although the pitch adjusting structure is arranged inside the drill rig mounting platform in the above embodiment, in some other embodiments, the whole drill rig mounting platform can be arranged as a pitch platform, and the pitch adjusting structure is arranged between the vehicle frame and the drill rig mounting platform.

[0071] As a preferred embodiment, in order to simplify the structure of the drill rig mounting device and improve the compactness of the TBM, the annular track is used as a moving track of a segment erector of the TBM.
