Description

Technical Field

[0001] This utility model belongs to the technical field of support devices for drilling rigs, and in particular relates to a cantilever tunneling machine, a rock drilling device, and a drilling rig installation module. Background Technology

[0002] When constructing in easily fractured strata, it is necessary to carry out initial support for the tunnel in a timely manner to ensure safety. Initial support operations generally include procedures such as pre-grouting with small guide pipes, assembling arch frames, and installing anchor bolts. The common feature of each procedure is that specific holes need to be drilled at the construction location to send small guide pipes, anchor bolts, prestressed anchor bolts, etc. into the strata.

[0003] Currently, in construction projects that use cantilever tunneling machines as excavation equipment, it is generally necessary to equip them with corresponding construction equipment for support operations, such as anchor bolt trolleys and arch frame trolleys. Different construction equipment are relatively independent, and the relevant equipment for support operations is generally located behind the cantilever tunneling machine, making it difficult to provide timely support.

[0004] Patent application CN113833486A discloses a multi-functional cantilever tunnel boring machine (TBM). This TBM integrates an anchor drilling rig assembly (equivalent to a rock drilling device). The anchor drilling rig assembly includes a drilling rig mounting module and a drilling machine mounted on the mounting module. Specifically, the mounting module includes a drill arm (main arm) with two rotary reducers mounted on it. The rotation axes of the two rotary reducers are perpendicular to each other. For ease of description, the two rotary reducers can be defined as the first rotary reducer and the second rotary reducer. The first rotary reducer is connected to one end of the drill arm, and its output end is connected to the second rotary reducer. The drilling rig's feed beam is connected to the output end of the second rotary reducer. By controlling the movement of the two rotary reducers, the drilling rig can swing up and down and left and right to drill anchor holes at different locations on the tunnel wall.

[0005] For geologically challenging strata, small-diameter pipe grouting is necessary beforehand within a defined area to ensure construction safety. When drilling the insertion holes for the small-diameter pipes, the pipes need a suitable external insertion angle from a front-to-back perspective, meaning the drilling rig should be tilted upwards and forwards; from a left-to-right perspective, the drilling location should cover a sufficient area. While the aforementioned anchor drilling rig assembly can adjust the rotary reducer to achieve a forward and upward tilting posture, the rig cannot swing left and right, making it unsuitable for small-diameter pipe drilling. The aforementioned patent application also does not disclose whether the drill arm can swing left and right. However, in reality, for highly integrated tunnel construction equipment (such as cantilever tunneling machines), left-to-right swinging of the drill arm can easily interfere with other components on the equipment, such as the mechanical arm assembling the arch frame. The range of left-to-right swing of the drill arm is limited, making it difficult for the anchor drilling rig assembly to achieve large-scale small-diameter pipe drilling operations. Furthermore, the relatively long drill arm means that even a small swing of the rig can result in a large swing, making it practically difficult to precisely control the rig's attitude and position by controlling the drill arm's swing. In other words, there is still room for improvement in the functionality of the aforementioned anchor drilling rig components. Utility Model Content

[0006] The purpose of this invention is to provide a drilling rig installation module to solve the technical problem that existing rock drilling devices lack flexibility and cannot simultaneously meet the requirements of anchor bolt and small guide pipe drilling. Another purpose of this invention is to provide a rock drilling device to solve the same technical problem. A further purpose of this invention is to provide a cantilever tunneling machine using the above-mentioned drilling rig installation module to solve the same technical problem.

[0007] To achieve the above objectives, the technical solution of the drilling rig installation module provided by this utility model is as follows:

A first slewing mechanism is installed at the front of the main boom, with its rotation axis parallel to the extension direction of the main boom. An adapter is installed at the output end of the first slewing mechanism, and a second slewing mechanism is installed on the adapter. The rotation axis of the first slewing mechanism is perpendicular to the rotation axis of the second slewing mechanism. A push beam mounting frame is installed at the output end of the second slewing mechanism. A push beam capable of swinging within a set range relative to the push beam mounting frame is installed on the push beam mounting frame, with its swing axis perpendicular to the rotation axis of the second slewing mechanism.

Simultaneously, when drilling small guide pipe insertion holes is required, the first and second rotation mechanisms can be adjusted to position the drilling rig in a suitable upward-sloping posture.

[0039] In order to provide a multifunctional rock drilling device that can perform both anchor drilling and small guide pipe drilling, the basic technical concept of this utility model is to change the connection relationship between the drilling rig propulsion beam and the second rotary mechanism, thereby increasing the degree of freedom for the drilling rig propulsion beam to swing relative to the second rotary mechanism. After adjusting the drilling rig to be in an upward-sloping drilling posture for the small guide pipe insertion hole, the drilling rig propulsion beam can also be adjusted to swing relative to the second rotary mechanism, so that the drilling rig swings left and right to cover the set range and complete the small guide pipe drilling.

[0040] The present invention will be further described in detail below with reference to the embodiments.

[0041] Specific embodiments of the rock drilling device provided by this utility model:

[0042] The structure of the rock drilling device in this embodiment is as follows: Figure 2 As shown, it can be configured on tunnel construction equipment, for example, it can be configured on such Figure 1 The image shows a cantilever tunneling machine including a chassis 2 and a cutting boom 1 mounted on the chassis 2. Specifically, as shown... Figures 2-5 As shown, the rock drilling device 3 includes a drilling rig mounting module and a drilling rig 301 mounted on the drilling rig mounting module. The drilling rig mounting module includes a main boom 302, a first slewing mechanism 305, a second slewing mechanism 306, a feed beam mounting frame 309, and a feed beam 308, etc. The drilling rig 301 is mounted on the feed beam 308, that is, the feed beam 308 has a drilling rig mounting position for mounting the drilling rig 301. Specifically, as shown... Figure 2As shown, the first slewing mechanism 305 is mounted on the main boom 302, and the second slewing mechanism 306 is mounted on the output end of the first slewing mechanism 305. When the output end of the first slewing mechanism 305 rotates, the second slewing mechanism 306 rotates synchronously. The push beam mounting bracket 309 is mounted on the output end of the second slewing mechanism 306. When the output end of the second slewing mechanism 306 rotates, the push beam mounting bracket 309 rotates synchronously. The push beam 308 is swayably mounted on the push beam mounting bracket 309, and a drive mechanism that drives the push beam 308 to sway relative to the push beam mounting bracket 309 is connected between the push beam 308 and the push beam mounting bracket 309. The sway axis of the push beam 308, the rotation axis of the first slewing mechanism 305, and the rotation axis of the second slewing mechanism 306 are perpendicular. It should be noted that the slewing mechanism refers to a mechanism with its own drive device (motor or hydraulic motor), and the power output shaft of the drive device can constitute the output end of the slewing mechanism. Of course, to output greater torque, the rotary mechanism may also include a reducer connected to the power output shaft of the drive unit, with the reducer's output shaft forming the output end of the rotary mechanism. Preferably, whether it is the first rotary mechanism 305 or the second rotary mechanism 306, in the presence of a reducer, the reducer can be selected as a worm gear reducer.

[0043] Specifically, such as Figure 5 and Figure 6 As shown, the propulsion beam 308 can be hinged to the propulsion beam mounting frame 309, specifically via a pin. The driving mechanism between the propulsion beam 308 and the propulsion beam mounting frame 309 is a drive cylinder 310. Both ends of the drive cylinder 310 are hinged to the propulsion beam 308 and the propulsion beam mounting frame 309, respectively. The extension and retraction of the drive cylinder 310 can cause the propulsion beam 308 to swing relative to the propulsion beam mounting frame 309. The drive cylinder 310, the propulsion beam 308, and the propulsion beam mounting frame 309 form a more stable triangular structure, which can improve the stability of the drilling rig 301 during drilling operations. The worm gear reducer is self-locking, preventing accidental rotation of the slewing mechanism during rock drilling.

[0044] In other embodiments, a rotary mechanism can be used to drive the propulsion beam 308 to swing relative to the propulsion beam mounting frame 309, and the drive device configured in the rotary mechanism itself constitutes the drive mechanism for driving the beam to swing.

[0045] In this embodiment, during operation, Figure 2 In the state shown, the second rotating mechanism 306 can be adjusted to rotate the push beam 308 to the position indicated. Figure 8 As shown in the upward position, anchor bolt drilling can then be performed on the tunnel roof. Adjust the first slewing mechanism 305 and the second slewing mechanism 306 to rotate the propulsion beam 308 to the position indicated by the image. Figure 9As shown in the downward-sloping state, anchor bolt drilling can be carried out on the bottom and slope of the tunnel, thereby achieving drilling operations in all directions around the tunnel.

[0046] For surrounding rock with poor geological conditions, if small guide pipes and grouting are required during construction, the rock drilling device 3 in this embodiment can also be successfully completed. Specifically, in Figure 2 In the indicated state, the second rotating mechanism 306 can be adjusted (rotated 180 degrees) to rotate the push beam 308 to the position shown. Figure 7 As shown in the upward-sloping posture, the drilling rig 301 can drill ahead of the small guide pipe insertion hole. At the same time, according to actual needs, the propulsion beam 308 can be adjusted to swing relative to the propulsion beam mounting frame 309, thereby realizing the left and right swing of the drilling rig 301. This allows the drilling rig 301 to have a certain coverage area, thus meeting the drilling requirements of the small guide pipe.

[0047] Analysis shows that the rock drilling device 3 in this embodiment can simultaneously perform small guide pipe drilling and anchor bolt drilling operations at different locations around the tunnel, offering more functions. When mounted on tunnel construction equipment, it can achieve multiple uses in one machine.

[0048] To move the drilling rig 301 to a more forward position for easier drilling, the main boom 302 in this embodiment can be a telescopic boom. The first slewing mechanism 305 is installed at the telescopic output end of the telescopic boom. During operation, the telescopic output end of the telescopic boom extends forward, pushing the drilling rig 301 to a more forward position. Of course, in other embodiments, the main boom 302 can also be a fixed-length main boom 302, such as... Figure 1 As shown, tunnel construction equipment is generally equipped with a translation platform 4 that can move back and forth. When the travel is sufficient, the translation platform 4 can move the drilling rig 301 to a forward position.

[0049] Furthermore, to expand the range of the drilling rig 301's left-right swing, the main boom 302 can also be sway-mounted on the translation platform 4 during installation. Specifically, a slewing mechanism can be installed on the translation platform 4, and the main boom 302 is mounted on the output end of this slewing mechanism via a base 304. In this case, the left-right swing of the main boom 302 can also drive the drilling rig 301 to swing to different positions. Of course, the swing range of the main boom 302 should be limited to avoid interfering with other mechanisms.

[0050] Considering that arch frames also need to be assembled during tunnel construction, in order to further improve the functionality of rock drilling device 3, such as Figure 2 As shown, the main boom 302 is also equipped with an arch-grabbing device 303, which includes an arch frame clamping mechanism 3031. The arch frame clamping mechanism 3031 is existing technology and can specifically adopt the arch frame clamping mechanism 3031 configured on the existing arch frame trolley. During construction, the arch frame clamping mechanism 3031 can grab the arch frame and, with the movement of the main boom 302, send the arch frame to the assembly position.

[0051] To enable the arch-grabbing device 303 to better adapt to arches of different positions and sizes, in this embodiment, an adapter seat is installed at the output end of the first slewing mechanism 305, and both the arch-grabbing device 303 and the second slewing mechanism 306 are mounted on the adapter seat. In this case, adjusting the first slewing mechanism 305 can also adjust the posture of the arch-grabbing device 303, thereby adapting to different arches. Of course, in other embodiments, the arch-grabbing device 303 can also be installed in other locations, for example, it can be directly installed on the main boom 302.

[0052] Because the drilling rig 301 has more degrees of freedom and multiple working states, in order to avoid the rock drilling rig 301 interfering with the normal movement of the propulsion beam 308, in this embodiment, as follows: Figure 2 As shown, the adapter seat is equipped with a swing mechanism 307. The swing axis of the swing mechanism 307, the rotation axis of the first rotation mechanism 305, and the rotation axis of the second rotation structure are perpendicular to each other. The arch-grabbing device 303 is installed at the output end of the swing mechanism 307. Thus, during operation, the swing mechanism 307 can be adjusted to make the arch-grabbing device 303 swing away from the side of the propulsion beam 308, such as... Figure 4 , Figure 8 and Figure 9 As shown, this avoids interference between the arch-grabbing device 303 and the drilling rig 301, while also ensuring the overall compactness of the drilling rig installation module. The swing mechanism 307 can be a rotary mechanism or a swing seat driven by a hydraulic cylinder. Of course, in other embodiments, the size of the adapter seat can be appropriately increased to allow for a larger distance between the arch-grabbing device 303 and the second rotary mechanism 306, in which case the arch-grabbing device 303 can be directly fixed to the adapter seat.

[0053] like Figure 3 As shown, the arch-grabbing device 303 includes a folding arm that can be folded in two stages. Specifically, the arch-grabbing device 303 includes a connecting seat 3032 connected to the adapter seat, a primary folding arm 3033, a secondary folding arm 3034, a hydraulic cylinder connected between the primary folding arm 3033 and the secondary folding arm 3034 to drive the secondary folding arm 3034 to swing relative to the primary folding arm 3033, and a hydraulic cylinder connected between the connecting seat 3032 and the primary folding arm 3033 to drive the primary folding arm 3033 to swing relative to the connecting seat 3032. Simultaneously, a swing seat 3035 is also provided on the secondary folding arm 3034. The swing axis of the swing seat 3035 is perpendicular to the folding rotation axis of the folding arm. A hydraulic cylinder for driving the swing seat 3035 to swing is connected between the swing seat 3035 and the secondary folding arm 3034. The arch-gripping mechanism 3031 is mounted on the swing seat 3035. In this embodiment, the arch frame clamping mechanism 3031 is mounted on a multi-joint, multi-degree-of-freedom robotic arm. During use, the posture of the arch frame clamping mechanism 3031 can be adjusted flexibly to adapt to different arch frames.
