Description

Technical Field

[0001] This invention relates to the field of full-face tunneling equipment, and in particular to a support equipment mounting device, a support system, and a tunneling machine. Background Technology

[0002] Full-face tunneling machines (MTBGs) are widely used in the construction of lined or unlined tunnels or adits, offering advantages such as high construction efficiency, good safety, and minimal impact on the surrounding environment. During TMBG construction, it is often necessary to reinforce and support the construction site. For example, in situations with adverse geological conditions, a support system is required to pre-support and reinforce the surrounding rock to ensure the safety of construction personnel and the smooth passage of the TMBG.

[0003] Based on their application, support systems are generally classified into bolt drilling systems, cable drilling systems, emergency jet grouting systems, injection molding systems, and advanced drilling systems. Bolt drilling systems are used for bolt support, cable drilling systems for cable support, emergency jet grouting systems to address situations where weak and fractured surrounding rock cannot stabilize itself, injection molding systems to address situations where rock collapse affects tunnel boring machine (TBM) progress, and advanced drilling systems for advanced geological treatment of the TBM.

[0004] Since the location requiring support often surrounds the tunneling machine, the support system, after installation, should have a sufficient working range around the tunneling machine. This working range is typically 360° around the tunneling machine. To meet this requirement, a mounting device needs to be installed on the main beam of the tunneling machine. The mounting device includes a circular track, and a support equipment trolley that can move along the circular track is installed on the circular track. The support equipment trolley is used to drive the support equipment to work at different positions.

[0005] In practical engineering, the support system is often positioned at the front of the tunnel boring machine (TBM), close to the tunnel face. However, because the upper and lower parts of the TBM house personnel access, material transport areas, cutterhead operating areas, and lower muck removal areas, especially when muck accumulates at the bottom of the tunnel, requiring an excavator to be driven under the TBM for rapid muck removal, the top and bottom spaces of the TBM cannot be encroached upon. Therefore, in existing technology, the circular track of the support system is generally divided into upper, lower, left, and right track sections. When the TBM is operating normally and not using 360° support, the upper and lower track sections are not installed to ensure personnel access, material transport, cutterhead operating space, and lower muck removal space above and below the TBM. When the support system needs to be used within a 360° range, the upper and lower track sections must be manually connected to the left and right track sections. The manual disassembly and assembly of the upper and lower track sections is labor-intensive and inefficient, and frequent disassembly can adversely affect the subsequent accuracy and reliability of the track.

[0006] To address the issues of high labor intensity and low efficiency in disassembling and assembling support equipment tracks, the applicant's invention patent (authorization announcement number CN106545345B, authorization announcement date July 12, 2019) provides a rapid mounting device for advanced drilling rigs. In this patent, the applicant proposes setting an opening on the traveling platform above the tunneling machine. Lifting cylinders are installed at both ends of the upper track section between the upper track section and the main beam. When no support work is being performed, the support equipment is parked on the upper track section, with both ends separated from the left and right track sections. The lifting cylinders are in a retracted state, and the opening on the lifting platform is covered by a cover plate, concealing the support equipment beneath the traveling platform. When support work is required, the cover plate is removed, and the upper track section is lifted using the lifting cylinders. The two ends are then manually connected to the left and right track sections.

[0007] The above structure can improve the efficiency of deploying the support system to some extent by setting up lifting cylinders. However, since it is still necessary to connect and disassemble the upper track section with the left and right track sections, and to disassemble and assemble the cover plate, the lower track section still adopts the traditional disassembly and assembly method to adapt to different construction scenarios. Therefore, the deployment efficiency of the support system is still difficult to achieve the expected results. Furthermore, after repeated disassembly and assembly, inaccurate positioning will still occur between different track sections, which will further reduce work efficiency. Summary of the Invention

[0008] The purpose of this invention is to provide a support equipment mounting device to solve the problems of low deployment efficiency and easy decline in component matching accuracy of existing support devices.

[0009] Meanwhile, the present invention also aims to provide a support system and a tunneling machine that use the above-mentioned support equipment mounting device.

[0010] To solve the above problems, the support equipment mounting device of the present invention adopts the following technical solution: The support equipment mounting device includes a connecting frame for connecting with a tunneling machine. The connecting frame includes support rails. The support rails include a left support rail and a right support rail arranged at intervals on the left and right sides, and whose projections in the front and rear directions form a bracket shape. The intervals between the upper ends and the lower ends of the left and right support rails respectively form front and rear passages. Support equipment trolleys are respectively arranged on the left and right support rails. The support equipment trolleys are equipped with trolley drive devices for driving them to move along their respective rails. The support equipment trolleys on at least one of the left and right support rails are arranged through a moving rail provided on the support rail. The support equipment trolleys are guided and cooperate with the moving rails. The moving rails are equipped with guide rail drive devices for driving them to move along their respective support rails. Through the relative movement of the moving rails, support rails, and support equipment trolleys, the support equipment can cover a set angle range in the circumferential direction of the tunneling machine.

[0011] Furthermore, the support equipment trolleys on the left and right support rails are arranged via moving rails, with the moving rails on the left and right support rails being the left moving rail and the right moving rail, respectively.

In its initial state, the gaps between the upper ends and the lower ends of the left and right support rails form front and rear passageways, thus avoiding interference with personnel access, material transport areas, cutterhead areas, and lower slag removal areas above and below the tunneling machine. During support operations, the movement of the moving rail relative to the support rails and the movement of the support equipment trolley relative to the moving rails at least partially cover these front and rear passageways, ensuring that the support equipment covers a set angle range around the tunneling machine, meeting the support range requirements. During use, the movement of the support equipment trolley is driven by a trolley drive device, and the movement of the moving rails is driven by a guide rail drive device, requiring no manual intervention, thus saving manpower and offering high efficiency. Furthermore, since there is no disassembly or assembly of parts, the fitting accuracy between components is not affected.

[0070] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0071] During the construction process, the space around the tunneling machine is relatively large, except for the top and bottom which need to be used as personnel passages, material transportation areas, cutting tool transport areas, and lower slag removal areas. The space on the left and right sides is sufficient to meet the needs of deploying support equipment. Therefore, the support equipment mounting device can be deployed on the left and right sides of the tunneling machine for a long time and be ready at any time.

[0072] Considering that the space at the top and bottom of the tunnel boring machine (TBM) cannot be occupied for extended periods, and that the support equipment often needs to reach the top and bottom of the TBM for support operations (i.e., covering a set angle range around the TBM), a composite track structure can be used. This structure combines support rails and moving rails. The support equipment trolley is mounted on the moving rail. When support operations are needed at the top and bottom of the TBM, the support equipment is moved to the working position by the movement of the moving rail relative to the support rail and the movement of the support equipment trolley relative to the moving rail. At other times, the track does not encroach on the space at the top and bottom of the TBM. This satisfies the following requirements: when support operations are not needed at the top and bottom of the TBM, the support equipment track avoids these areas; when support is needed, the support equipment can be moved to the working position. Switching between these two positions does not require disassembly and reassembly of the track, resulting in high efficiency, low labor intensity, and avoiding damage to the support equipment mounting device due to frequent disassembly and reassembly.

[0073] Based on the above inventive concept, the support equipment mounting device of the present invention adopts the following basic technical solution: the support equipment mounting device includes a connecting frame, which is used to connect with a corresponding part of the tunneling machine, such as the main beam 1 of the tunneling machine host. Of course, in some embodiments, when the required support position is not located around the main beam 101, the connecting frame can also be deployed on the rear supporting system after the main machine of the tunneling machine, such as on the belt conveyor bridge. Regarding the deployment position of the support equipment on the tunneling machine, it is often designed according to the specific construction needs in practice. This is the prior art, so it will not be described in detail here.

[0074] Another major function of the connector frame is to connect support equipment. Figure 1-6The diagram shows Embodiment 1 of the support equipment mounting device of the present invention. In Embodiment 1, the support equipment is an advanced drilling rig 102. The connecting frame includes support rails, which include a left support rail 103 and a right support rail 104 arranged at intervals. The projections of the left and right support rails in the front-back direction form a bracket shape. The brackets can be parentheses "()", square brackets "[]", or curly brackets "{}", etc. The characteristic is that the two parts are opposite each other, and the upper ends and lower ends of the left and right parts have parts that approach each other but do not touch. The intervals between the upper ends and the lower ends of the left and right support rails respectively form front and rear passage openings 105 for personnel or equipment to pass through, thereby avoiding interference with the personnel passages, material transport areas, cutting tool transport areas, and lower slag removal areas of the upper and lower parts of the tunneling machine.

[0075] Support equipment trolleys 106 are arranged on the left and right support rails respectively. The function of the support equipment trolleys 106 is to serve as the direct carrier for the support equipment and to install the support equipment. The support equipment trolleys 106 are equipped with trolley drive devices 107, which are used to drive the support equipment trolleys 106 to move along their respective rails, so as to bring the support equipment to different positions for related operations. As a typical structure, the support equipment trolley includes a frame 61, on which upper rail wheels 62 and lower rail wheels 63 are provided. The upper rail wheels 62 and lower rail wheels 63 are used to cooperate to lock the frame 61 onto the corresponding guide rails so that the frame 61 can move along the guide rails. An equipment platform 64 is also provided on the frame 61. One side of the equipment platform 64 is hinged to the frame 61, and a pitch adjustment cylinder 65 is provided between the other side and the frame 61. A slewing device 66 is provided on the equipment platform, and an equipment connecting plate 67 is provided on the slewing device 66. The equipment connecting plate 67 is used to connect with the support equipment. In use, the support equipment can be fixedly connected to the equipment connecting plate 67. The pitch angle is adjusted by the pitch adjustment cylinder 65, and the slewing angle is adjusted by the slewing device 66 to realize support operations in different directions and positions.

[0076] Since neither the left nor right support rails cover the top and bottom of the tunneling machine circumferentially, in order for the support equipment trolley 106 to reach the aforementioned positions, the support equipment trolley 106 on at least one of the left and right support rails is arranged via a movable rail provided on the support rail. The movable rail is equipped with a guide rail drive device 108 for driving it to move along the support rail it is on. This creates a structure similar to a telescopic track between the movable rail and the support rail, allowing the support rail to be extended during use. The support equipment trolley 106 is guided and cooperates with the movable rail, and the relative movement of the movable rail, the support rail, and the support equipment trolley allows the support equipment to cover a set angle range circumferentially around the tunneling machine.

[0077] It is important to emphasize here that, although in Figure 1-6 In the illustrated embodiment, movable rails are respectively installed on the left and right support rails. However, if the support equipment can cover a certain working range around the tunnel circumference, a movable rail can also be installed on only one of the support rails. In this case, the insufficient upward extension length of the support rail can be compensated by moving the movable rail upward relative to its supporting rail, and the insufficient downward extension length of the support rail can be compensated by moving the movable rail downward relative to its supporting rail. When a movable rail is installed on only one of the support rails, the support equipment trolley on the other support rail can directly cooperate with the support rail.

[0078] As a preferred embodiment of the support equipment mounting device of the present invention, in Embodiment 1 of the support equipment mounting device of the present invention, as follows: Figure 1-6 As shown, the support equipment trolleys 106 on both the left and right support rails are arranged via moving rails, specifically the left moving rail 109 and the right moving rail 110. The left moving rail 109 is guided to the left support rail 103, and the right moving rail 110 is guided to the right support rail 104. By setting moving rails on the left and right support rails respectively, the required length of a single support rail can be shortened through their mutual cooperation, further increasing the size of the front and rear access openings 105 and freeing up more space at the top and bottom of the tunneling machine.

[0079] In addition, Figure 1-6 In the illustrated embodiment, both the left support rail 103 and the right support rail 104 are arc-shaped guide rails, more specifically, circular arc-shaped guide rails, and are symmetrically arranged left and right. Correspondingly, the left moving rail 109 and the right moving rail 110 are also circular arc-shaped guide rails, with the same length as the left support rail 103 and the right support rail 104. This structure ensures that the support equipment maintains a consistent distance from the tunnel wall during the circumferential movement of the tunnel (of course, only when the tunnel cross-section is circular). Therefore, in some other embodiments, the shapes of the left support rail 103 and the right support rail 104 can also be elliptical arcs, other arc shapes, or non-arc shapes. Similarly, the shapes of the left moving rail 109 and the right moving rail 110 can also be elliptical arcs, other arc shapes, or non-arc shapes, and their shapes do not necessarily need to be identical to those of the left support rail 103 and the right support rail 104. In addition, since the moving rail mainly serves to "fill in the gaps" and is used to extend the support rail to the front and rear access ports, its length does not need to be the same as the support rail. It only needs to ensure that it does not interfere with the front and rear access ports 105 when it is at least one position on the corresponding support rail.

[0080] In a preferred embodiment, such as Figure 2As shown, the left support rail 103 and the right support rail 104 are coplanar in the front-to-back direction. In use, this allows the support equipment mounted on the two support equipment trolleys 106 to operate at the same cross-section of the tunnel, and the symmetrical structure makes arrangement easier, reducing installation difficulty. It is important to emphasize that although the left support rail 103 and the right support rail 104 are arranged coplanarly in the front-to-back direction in the above embodiment, those skilled in the art should understand that in other embodiments, the left support rail 103 and the right support rail 104 can be staggered front-to-back, still solving the problems of low deployment efficiency and decreased precision of component fitting in existing support devices.

[0081] In the above embodiment, the set angle range is 360°. This allows the support equipment to fully cover the tunnel's circumference during operation. In other embodiments, when a 360° tunnel coverage is not required, the set angle range can be designed according to actual needs, specifically by adjusting the length, shape, and travel distance of the moving rail.

[0082] In a preferred embodiment, a rack and pinion gear structure is correspondingly provided between the left moving rail 109, the right moving rail 110, the left support rail 103, and the right support rail 104. The guide rail drive device 108 is connected to the gear transmission of the rack and pinion gear structure. Specifically, the rack 111 of the rack and pinion gear structure is provided on the left and right moving rails. Grooves 112, made of channel steel, are provided on the front and rear sides of the rack 111. After the rack 111 and the grooves 112 on the front and rear sides are combined, the whole structure forms an "I"-shaped cross-section. The left and right moving rails are respectively composed of corresponding racks and grooves. An upper clamping wheel 113 and a lower clamping wheel 114 are provided on the support rail. The connection between the moving rail and the support rail is achieved by the upper and lower clamping wheels engaging with the convex edge on the lower side of the moving rail. The gear connected to the guide rail drive device 108 is a guide rail drive gear 115, which is mounted on a connecting frame. The guide rail drive device 108 is a motor.

[0083] Of course, although the above embodiments employ a rack and pinion gear structure between the support rail and the moving rail, those skilled in the art should understand that in other embodiments, a synchronous belt can also be used. In this case, the moving rail can be fixedly connected to the corresponding synchronous belt, and its synchronous movement can be driven by the synchronous belt. In the above embodiments, the moving rail and the support rail are connected by upper and lower clamping wheels. In other embodiments, the upper and lower clamping wheels can be replaced by upper and lower clamping blocks. The positions of the racks can also be interchanged.

[0084] Based on the above implementation method, the upper track wheel 62 and lower track wheel 63 on the support equipment trolley 106 cooperate with the convex edge on the other side of the moving rail to install the support equipment trolley 106 on the moving rail. A trolley drive gear 116 is provided on the frame. The trolley drive device 107 adopts a trolley drive motor and is connected to the corresponding trolley drive gear 116 for transmission. The rack is also provided with trolley drive gear mating teeth for cooperating with the trolley drive gear, thereby making the rack a double-sided rack.

[0085] Similar to the cooperation between the moving rail and the support rail, the support equipment trolley 106 can also be connected to the moving rail using a synchronous belt. In this case, the support equipment trolley can be fixedly connected to the corresponding synchronous belt, and its synchronous movement is driven by the synchronous belt. The upper and lower track wheels can also be replaced with upper and lower clamping blocks. The positions of the gears and racks can also be interchanged.

[0086] In another preferred embodiment, the connecting frame is equipped with a linear track 117 extending front to back and a linear drive device 118 for driving the connecting frame to reciprocate along the linear track. Specifically, the linear track 117 can be deployed on a tunneling machine, and the connecting frame can cooperate with the linear track through a wheel box 119 provided thereon. The structure of the wheel box 119 is as follows: Figure 3 As shown, it includes a housing 191, an axle 192, and rollers 193, where rollers 193 are V-shaped wheels. The linear drive device 118 can be selected from hydraulic cylinders, lead screws, or timing belts as needed, which will not be described in detail here.

[0087] Combination Figure 1 , Figure 6 It can be seen that when no support work is required for the top and bottom of the tunnel, the left and right moving rails are arranged symmetrically, and there are passageways 105 between the upper and lower ends of the left and right support rails. At this time, the support equipment can be driven to perform support work on the left and right sides of the tunnel by moving the two support equipment trolleys 106 relative to the moving rails. When the support equipment is in standby, it can also be stored in this position. When the top and bottom of the tunnel need to be supported, the two moving rails can be driven to rotate clockwise (counterclockwise is also possible), so that the working range of the auxiliary equipment can cover the top and bottom of the tunnel. The combination of the two states can make the working range of the auxiliary equipment cover the circumference of the tunnel.
