Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of tunneling construction equipment, and particularly relates to a multifunctional roadway / tunnel tunneling construction equipment. BACKGROUND

[0002] Coal mine system arrangement in the roadway of rock mass (hereinafter referred to as rock roadway) and railway, highway and water and electricity system arrangement in the tunnel of rock mass (hereinafter referred to as rock tunnel) tunneling construction, drilling and blasting rock has been the most commonly used rock breaking method, other rock breaking methods have TBM (Tunnel Boring Machine, full-face tunnel boring machine, including open type and shield type) full-face mechanical rolling and scraping rock breaking, high-power cantilever type horizontal axis hard rock tunneling machine partial section pick cutting rock breaking.

[0003] For the adaptability of the roadway and tunnel (hereinafter referred to as roadway / tunnel) arranged in the rock mass in terms of pitch angle and advancing direction change, roadway / tunnel section and length size, rock hardness, surrounding rock stability change and other factors, drilling and blasting rock is obviously superior to TBM, in addition, TBM has large volume, complex structure, and its cost is much higher, the installation and removal cycle is long, the rock breaking energy consumption per unit volume and the per-meter engineering cost are obviously much higher, so even if TBM has been on the market for many years, it still cannot completely replace the traditional drilling and blasting rock method.

[0004] The cantilever type horizontal axis high-power hard rock tunneling machine has been on the market for more than twenty years, because there are problems such as high noise of pick cutting hard rock, extremely high dust concentration, serious harm to the occupational health of construction workers, high per-meter engineering cost (mainly due to high pick consumption, high equipment maintenance and equipment depreciation and financial costs), and if the rock hardness is greater than the Protodyakonov hardness coefficient 7, the construction speed will be significantly reduced, especially when the Protodyakonov hardness coefficient of rock is greater than 9, it is almost not feasible to use hard rock tunneling machine to break rock, so it has not been widely used in roadway / tunnel tunneling construction, and only a few urban subway tunnel constructions have to use high-power cantilever type horizontal axis hard rock tunneling machine due to the limitation of conditions, neither can they use conventional drilling and blasting rock method, nor do they have the conditions to use TBM construction, but the effect is very unsatisfactory.

[0005] It can be foreseen that drilling and blasting rock is still an irreplaceable rock breaking method for tunneling construction in the current and a long time in the future. However, the span of the rock roadway of the coal mine is mostly below 6.0 m. Since the span of the roadway is less than the width required for the intersection of two equipment intersection, the engineering conditions for the operation of two or even three or more construction equipment with different functions in the working face are not met, and therefore, there are at least two outstanding problems in the rock roadway tunneling construction of many coal mines at present. One is that the mechanization level of construction is low, and some operation contents can only be completed by manual operation of the leg type rock drill and the single pneumatic anchor rod drill, which has high labor intensity and low efficiency. The other is that the construction speed is low. Even after long-term development, the monthly footage of a single head is mostly below 80 m, and there are few cases of reaching 80 m or above, and even fewer cases of reaching 100 m or above. However, with the continuous high-intensity mining, the shallow coal resources are rapidly decreasing, and in recent years, more and more deep resources are being mined, which leads to high gas content of deep coal resources. It is necessary to extract the gas in the rock roadway near the coal seam before mining to greatly reduce the gas content of the coal seam and create the necessary conditions for subsequent safe mining. However, the current rock roadway tunneling monthly footage is difficult to meet the needs of normal production of the mine.

[0006] In summary, it is necessary to develop a multifunctional roadway / tunnel tunneling equipment based on the drilling and blasting method with two or more functions. On this basis, further development of a supporting construction equipment matched with the equipment and arranged behind the equipment, and matching the functions of the front construction equipment, can form a high-efficiency complete construction equipment, greatly improve the mechanization degree and construction speed of small-span roadway / tunnel construction, and reduce the labor intensity of the construction workers.

[0026] After the above technical scheme is adopted, the utility model has the following beneficial technical effects:

[0027] First, in view of the narrow and unchangeable working environment of small-span roadway / tunnel construction, the utility model creatively takes the roadway / tunnel tunneling equipment and the transfer belt conveyor (also known as secondary transport) which is movably connected with the roadway / tunnel tunneling equipment and overlapped under the unloading end of the scraper conveyor as functional equipment units of complete construction equipment, and according to the basic production process, operation content and sequence of roadway / tunnel construction, the front roadway / tunnel tunneling equipment and the secondary transport behind the same are planned and arranged in function positioning and distribution, mechanical structure and connection mode between them: the drilling devices are arranged on the roadway / tunnel tunneling equipment and the secondary transport, the drilling device arranged on the roadway / tunnel tunneling equipment is used for drilling blast holes in the rock mass of the working face in front of the chassis and / or implementing anchor rod support on the surrounding rock of the roadway / tunnel, and the drilling device arranged on the secondary transport is used for implementing supplementary anchor rod / anchor cable support on the surrounding rock of the roadway / tunnel, the connection mode between the front and rear equipment is convenient to connect and split, and on this basis, the anchor rod / anchor cable support equipment which can minimize the occupation of the site space and independently walk on the track is created.

[0028] Second, the substantial technical upgrading and performance improvement of the secondary transport are as follows:

[0029] ① The tail end of the secondary conveyor is connected to the tunnel / tunnel excavation equipment in a quick-disassembly connection method. The secondary conveyor can be quickly connected to the tunnel / tunnel excavation equipment to transfer the rock debris unloaded by the tunnel / tunnel excavation equipment to the tail load section of the telescopic belt conveyor. After the rock debris is transferred, the connection between the secondary conveyor and the tunnel / tunnel excavation equipment can be quickly disconnected. This allows the secondary conveyor to perform additional rock bolt / anchor cable support work on the tunnel / tunnel surrounding rock in parallel operation without being affected by the drilling of blasting rock holes or the implementation of rock bolt support on the tunnel / tunnel surrounding rock by the tunnel / tunnel excavation equipment in front.

[0030] ② A tail section was added to the tail end of the secondary conveyor. After disconnecting from the tunnel / roadway excavation equipment in front, the rigid wheels of the tail section straddle the tail rails on both sides of the load-bearing section of the telescopic belt conveyor, or straddle the rails laid on the roadway floor. Furthermore, a travel drive motor was installed in the head section and / or tail section of the secondary conveyor, giving it the power to move autonomously. This significantly improves the flexibility and efficiency of its bolt / cable support operations and expands its operational coverage. A brake was also installed in the tail section, hydraulically interlocked with the tail motor, giving the secondary conveyor an automatic braking function. When disconnected from the tunnel / roadway excavation equipment in front, the brake effectively prevents it from slipping uncontrollably on the slope due to downward force.

[0031] Third, a special lifting mechanism has been added to the tunnel / tunnel excavation equipment. This lifting mechanism can be used to lift the tail end of the transfer belt conveyor, which can greatly improve the speed of connecting and disconnecting the unloading end of the secondary conveyor and the tunnel / tunnel excavation equipment.

[0032] Fourth, drilling devices are installed on both sides of the chassis of the tunnel / tunnel excavation equipment. This enables it to not only perform rock cuttings loading and transportation functions, but also to create boreholes for blasting rock and even provide anchor bolt support for the surrounding rock of the tunnel / tunnel. Thus, it becomes a multi-functional tunnel / tunnel excavation equipment. Furthermore, a boom sliding mechanism and lifting seat that can slide forward and backward are installed on its chassis, which can further increase the range of forward and backward movement of the boom and the drilling mechanism. It also gives the rear end of the boom a lifting function. This solves the problem of blind spots in the drilling operation caused by installing the drilling devices on both sides of the equipment chassis and setting the rock cuttings loading mechanism at the front of the equipment chassis, as well as the problem of the drilling devices touching the working face rock wall when the rock cuttings loading mechanism is loading the foremost rock cuttings. It also makes it easier for the drilling devices to create boreholes for blasting rock and perform anchor bolt support operations over a larger area without moving the entire equipment.

[0033] In summary, compared with existing technologies that use two or more single-function construction devices to work at the working face in rotation, the multi-functional tunnel / tunnel excavation equipment of this invention not only significantly improves construction speed by saving the time of alternating between different functional devices, but also allows for the efficient loading and transportation of rock debris, the creation of blasting boreholes within the working face rock mass, and the application of this invention to the surrounding rock of small-span tunnels / tunnels where space constraints preclude the use of two or more different functional devices. Operations such as anchor bolt support can be mechanized. Furthermore, while retaining the essential rock debris transfer function of the secondary conveyor system, this invention incorporates a series of profound and substantial technical modifications and performance and functional enhancements. These include a quick-connect and detachable connection method between the secondary conveyor and the preceding tunnel / tunnel excavation equipment, and the installation of a walking unit with driving force at its tail end, which serves as the carrier for a drilling device. This allows the secondary conveyor system to perform supplementary anchor bolt / cable support for the surrounding rock of the tunnel / tunnel in parallel operations from the rear, without being hindered by the preceding tunnel / tunnel excavation equipment. These technical measures will significantly improve the mechanization level, construction speed, and operational efficiency of small-span tunnel / tunnel excavation based on the drill-and-blast method, while reducing labor intensity. In addition, this utility model has significantly improved the performance of two existing supporting construction equipment for tunnel / tunnel excavation—the secondary transporter and the muck loader—through systematic, in-depth, and substantial technical transformation and performance enhancement. This has added new functions to both equipment and made their combination more reasonable, achieving a synergistic technical effect. Both equipment have significant characteristics such as small space occupation, flexible and efficient operation, and minimal mutual interference. They are particularly suitable for small-span tunnel / tunnel excavation and will thus significantly promote the technological progress of small-span tunnel / tunnel excavation.

[0061] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of this utility model, but it is not intended to limit the scope of protection of the appended claims of this utility model.

[0062] like Figure 1 As shown, a multi-functional tunnel / tunnel excavation construction equipment includes a tunnel / tunnel excavation device 1, a transfer belt conveyor 2 (commonly known as "secondary transport"), and a retractable belt transporter 3.

[0063] like Figure 1 and Figure 2 As shown, the tunnel / tunnel excavation equipment 1 includes a chassis 11, which includes a frame and tracked walking parts installed on the left and right sides of the frame. The chassis 11 is equipped with a loading shovel 12, a drilling device 14b, a rock cutting mechanism 15, a scraper conveyor 17, and a lifting mechanism 16. The drilling device 14a is located on both sides of the chassis 11. In this embodiment, the drilling device 14a is installed on the chassis 11 via a boom sliding mechanism 13. The boom sliding mechanism 13 is used to eliminate the problem of blind spots in the operation of the drilling device 14b due to the installation of the drilling device 14b on both sides of the equipment chassis 11 and the rock cutting mechanism 15 at the front of the chassis. It also eliminates the problem of the drilling device 14b touching the working face rock wall when the rock cutting mechanism 15 is loading the foremost rock cutting. Furthermore, it can increase the forward and backward movement range of the drilling device 14b, so that the drilling device 14b can conveniently create boreholes for blasting rock and carry out anchor bolt support operations within a larger range.

[0064] The rock cuttings loading mechanism 15 cooperates with the loading shovel 12 to load the rock cuttings onto the scraper conveyor 7. The scraper conveyor 7 is located in the center of the frame and is used to transfer the rock cuttings to the transfer belt conveyor 2 behind the chassis 11.

[0065] like Figure 1 and Figure 3 As shown, the transfer belt conveyor 2 is used to transfer the rock debris unloaded from the scraper conveyor 17 to the telescopic belt conveyor 3. The drilling device 14b installed on the tunnel / tunnel excavation equipment 1 is used to create blasting rock boreholes in the working face rock mass in front of the chassis 11 and / or to implement anchor bolt support for the surrounding rock of the tunnel / tunnel. The drilling device 14a installed on the transfer belt conveyor 2 uses the transfer belt conveyor 2 as a carrier to implement additional anchor bolt / anchor cable support for the surrounding rock of the tunnel / tunnel.

[0066] like Figure 1 and Figure 3 As shown, the retractable belt conveyor 3 includes a tail assembly with a reversing roller and a tail load-bearing section connected to the tail assembly. Tracks, hereinafter referred to as tail tracks, are provided on both sides of the tail load-bearing section. The head unloading end of the transfer belt conveyor 2 is mounted above the head traveling section 21, which is equipped with rigid wheels, and is movable in both vertical and horizontal dimensions. The rigid wheels of the head traveling section straddle the tail tracks.

[0067] like Figure 4 As shown, the tail end of the transfer belt conveyor 2 is positioned below the unloading end of the scraper conveyor 17, overlapping with it, and is movably connected to the tunnel / tunnel excavation equipment 1. Based on this movable connection, the tail end of the transfer belt conveyor 2 can rotate relative to the tunnel / tunnel excavation equipment 1 in both vertical and horizontal dimensions. The tail end of the transfer belt conveyor 2 is equipped with a tail travel section 22 with rigid wheels. If the movable connection is disengaged, the rigid wheels of the tail travel section 22 straddle the tail track or a track (not shown) laid on the tunnel / tunnel floor. From a utility model perspective, both the head travel section 21 and / or the tail travel section 22 can be equipped with a hydraulic drive motor or electric motor that is drively connected to their rigid wheels. The hydraulic drive motor in the head travel section 21 is referred to as the head motor, and the hydraulic drive motor in the tail travel section 22 is referred to as the tail motor.

[0068] The tail section 22 is equipped with a brake that is connected to its wheel drive. Figure 11The diagram shows a left brake and a left tail motor located on the left side of the tail section, and a right brake and a right tail motor located on the right side of the tail section. A hydraulic control circuit is provided between the brake and the hydraulic oil input and return ports of the tail motors. When oil pressure from the tail motor's hydraulic oil input port is transmitted to the brake and reaches a predetermined value, the brake automatically releases its braking function. Conversely, when the oil pressure from the tail motor's hydraulic oil input port disappears or falls below the predetermined value, the brake automatically resumes its braking function. Figure 11 In the middle, Port A and Port B are two hydraulic connection ports between the two tail motors on the left and right sides of the tail travel section and the hydraulic valves that control the forward and backward movement of the tail travel section.

[0069] Combination Figure 2 and Figure 4 The chassis 11 is provided with a mounting mechanism 18 at the rear. The mounting mechanism 18 includes a support arm 181 and a rotating component 182. One end of the support arm 181 is connected to the chassis 11. The rotating component 182 is rotatably mounted above the other end of the support arm 181. The rotating component 182 includes two lugs 182a. The upper end of the lugs 182a is provided with a pin hole 182b. The pin hole 182b is provided with an opening. The two sides of the tail end of the conveyor belt 2 are provided with mounting pins 23, which are mounted on the pin holes 182b.

[0070] Combination Figure 2 and Figure 4 A lifting mechanism 16 is provided at the rear of the chassis 11. The lifting mechanism 16 is used to lift the tail end of the transfer belt conveyor 2 during the connection and disconnection operations between the tail end of the transfer belt conveyor 2 and the tunnel / tunnel excavation equipment 1. The lifting mechanism 16 includes a lifting arm 161 and a worm gear slewing bearing 162 driven by a hydraulic motor. The mounting end of the worm gear slewing bearing 162 is connected to the chassis 11. The lifting arm 161 is a telescopic sleeve type lifting arm with a built-in telescopic cylinder. One end of its outer sleeve is hinged to the output end of the worm gear slewing bearing 162. A lifting arm lifting cylinder 163 is provided between the output end of the worm gear slewing bearing 162 and the outer sleeve of the telescopic sleeve type lifting arm.

[0071] In this embodiment, the tail end of the transfer belt conveyor 2 is connected to the tunnel / tunnel excavation equipment 1 in front of it in a convenient and detachable manner. The transfer belt conveyor 2 can be quickly connected to the tunnel / tunnel excavation equipment 1 to transfer the rock debris unloaded by the tunnel / tunnel excavation equipment 1 to the tail load section of the telescopic belt conveyor 3 behind it. After the rock debris is transferred, the connection between the transfer belt conveyor 2 and the tunnel / tunnel excavation equipment 1 can be quickly disconnected. This allows the transfer belt conveyor 2 to efficiently provide additional rock bolt / anchor cable support to the tunnel / tunnel surrounding rock without being affected by the drilling of blasting rocks or the implementation of rock bolt support for the tunnel / tunnel surrounding rock caused by the tunnel / tunnel excavation equipment 1 in front of it.

[0072] The specific structure of some of the main components mentioned above is described in detail below.

A loading mechanism rotation power device 155 is provided between the rotating body 154 and the chassis 11.

[0074] Figure 6 The specific structure of the boom sliding mechanism 13 is shown, combined with Figure 2 A boom sliding mechanism 13, which can slide back and forth, is provided on the chassis 11. The boom sliding mechanism 13 includes a boom slide rail 133 and a boom slide seat 134. The boom slide rail 133 is longitudinally arranged on the boom base 131, and the boom base 131 is fixed to the chassis 11. The boom slide seat 134 is slidably or rollingly mounted on the boom slide rail 133. A sliding power device 132 is provided between the boom base 131 and the boom slide seat 134. The sliding power device 132 is preferably a telescopic cylinder, but it can also be other linear power devices. The rear end of the boom 1413 is movably mounted on the lifting seat 135 with its front end swinging in both vertical and horizontal dimensions. The lifting seat 135 is slidably mounted on the boom slide seat 134. A lifting power device (not shown in the figure) is provided between the lifting seat 135 and the boom slide seat 134. The lifting power device is preferably a telescopic cylinder, but it can also be other linear power devices. From the perspective of the utility model concept, the boom base 131 can be regarded as part of the chassis 11.

[0075] In this example, the sliding power device 132, which is disposed between the chassis 11 and the boom slide 134, generally refers to the power device that drives the boom slide to move relative to the slide rail. It includes both the boom slide being slidably mounted on the slide rail and moving relative to the slide rail, and the boom slide rolling on the slide rail and moving relative to the slide rail.

[0076] Of course, if the lifting seat 135 is not set, the rear end of the boom 1413 is mounted on the boom slide 134 in a way that its front end can swing in both vertical and horizontal dimensions (that is, the transition connecting seat 1411 is fixedly connected to the boom slide 134). The advantage is that the structure is simplified, but the flexibility of the drilling device 14b is reduced and its adaptability to the working environment will be worse.

[0077] First, the drilling device 14a installed on the transfer belt conveyor 2 is described.

[0078] like Figure 3 and Figure 7 As shown, the drilling device 14a includes a boom assembly 141 and a drilling mechanism 142 connected together. The boom assembly 141 includes a boom 1413 and hydraulic cylinders, connectors, etc., connected to the boom 1413. The boom 1413 is a telescopic boom with a built-in telescopic hydraulic cylinder. In this embodiment, the rear end of the boom 1413 is movably mounted on the transfer belt conveyor 2 with its front end swinging in both vertical and horizontal dimensions. The front end of the boom 1413 is movably connected to the drilling mechanism 142.

[0079] Figure 8 The specific structure of boom component 141 is shown, combined with Figure 3 , Figure 7 and Figure 9 The rear end of the boom 1413 is hinged to the transition connecting seat 1411 via a cross-hinged joint. The transition connecting seat 1411 is fixedly connected to or integrally set with the mounting seat 24 on the transfer belt conveyor 2. Two boom swing cylinders 1412 are provided between the rear of the boom 1413 and the transition connecting seat 1411. The rear end of the boom swing cylinder 1412 is hinged to the transition connecting seat 1411 via a cross-hinged joint, and its front end is hinged to the boom 1413. By extending and retracting the two boom swing cylinders 1412, the boom 1413 can be driven to swing its front end in both vertical and horizontal dimensions.

[0080] The front end of the boom 1413 is connected to the drilling carriage 1424 via connector III 1415, connector IV 1428, and rotary cylinder III 1416 (as shown in the figure, it is arranged longitudinally).

[0081] The front end of boom 1413 is hinged to one side of connector III 1415 via a cross joint c. Two swing cylinders 1414 of connector III are installed between one side of connector III 1415 and the front of boom 1413. The rear end of connector III swing cylinder 1414 is hinged to boom 1413, and its front end is hinged to one side of connector III 1415 via a cross joint d. By extending and retracting the two swing cylinders 1414, connector III 1415 can be driven to swing in both vertical and horizontal dimensions. The mounting end of rotary cylinder III 1416 is connected to the other side of connector III 1415, and its output end is connected to connector IV 1428. By rotating rotary cylinder III 1416, drilling mechanism 142 can be driven to swing around the rotation center of rotary cylinder III 1416. The drilling slide 1424 is rotatably mounted on the connector IV 1428 (the connector IV 1428 is optimized to be a pin with an inner hole, and the drilling slide 1424 is provided with a pin hole that rotatably engages with the pin with the inner hole). A drilling slide swing cylinder 1427 is provided between the connector IV 1428 and the drilling slide 1424. The pitch angle of the drilling mechanism 142 can be adjusted by extending and retracting the drilling slide swing cylinder 1427.

[0082] like Figure 9 As shown, the drilling mechanism 142 includes a power head 1422, a slide 1421, a drilling frame 1423, and a propulsion mechanism 1425. The power head 1422 is fixedly connected to or integrally formed with the slide 1421, and the slide 1421 is slidably mounted on the drilling frame 1423. The propulsion mechanism 1425 preferably adopts a hydraulic cylinder-wire rope speed-multiplying mechanism or a hydraulic cylinder-chain speed-multiplying mechanism. The propulsion mechanism 1425 is disposed between the slide 1421 and the drilling frame 1423 and is used to drive the slide 1421 to slide relative to the drilling frame 1423. With the speed-multiplying mechanism, the drilling depth can reach twice the hydraulic cylinder stroke, achieving a larger drilling depth with a smaller hydraulic cylinder stroke (length). The drilling mechanism 142 includes a drilling slide 1424, which is movably connected to the front end of the boom 1413. A drilling frame 1423 is slidably mounted on the drilling slide 1424. A drilling frame drive cylinder 1426 is provided between the drilling frame 1423 and the drilling slide 1424. The drilling frame drive cylinder 1426 can drive the drilling frame 1423 to slide forward relative to the drilling slide 1424, causing its front end to abut against the working face rock wall or surrounding rock wall, thereby increasing the stability of the drilling mechanism 142 during drilling operations. Alternatively, the drilling mechanism 142 can be configured without the drilling slide 1424, allowing the drilling frame 1423 to be directly movably connected to the front end of the boom 1413. This simplifies the structure of the drilling mechanism 142, but the stability of the drilling mechanism 142 during rock drilling operations is inferior to the aforementioned structure.

[0083] For ease of description, the drilling mechanism 142 without the drilling slide 1424 is referred to as Scheme A, and the drilling mechanism 142 with the drilling slide 1424 is referred to as Scheme B. When the drilling mechanism 142 adopts Scheme A, the drilling frame 1423 is rotatably mounted on the connector IV 1428, and a drilling frame swing cylinder is provided between the drilling frame 1423 and the connector IV 1428; when the drilling mechanism 142 adopts Scheme B, the drilling slide 1424 is rotatably mounted on the connector IV 1428, and a drilling slide swing cylinder 1427 is provided between the drilling slide 1424 and the connector IV 1428.

[0084] The following describes the drilling device 14b installed on the roadway / tunnel excavation equipment 1.

[0085] like Figure 2 and Figure 10 As shown, the drilling device 14b is installed on the tunnel / tunnel excavation equipment 1, and its structure and principle are roughly the same as those of the drilling device 14a installed on the transfer belt conveyor 2. The main difference is that the connection between the front end of the boom and the drilling mechanism is different.

[0086] like Figure 10 As shown, in this embodiment, the front end of the boom 1413 is connected to the drilling slide 1424 via connector I 1418, connector II 1420, rotary cylinder I 1417 (shown in the figure as longitudinally arranged), and rotary cylinder II 1419 (shown in the figure as vertically arranged).

[0087] Specifically, the front end of boom 1413 is connected to the mounting end of rotary cylinder I 1417, the output end of rotary cylinder I 1417 and the mounting end of rotary cylinder II 1419 are respectively connected to connector I 1418, and the output end of rotary cylinder II 1419 is connected to connector II 1420.

[0088] When the drilling mechanism 142 adopts the aforementioned scheme B, the drilling slide 1424 is rotatably mounted on the connector II 1420, and a drilling slide swing cylinder 1427 is provided between the drilling slide 1424 and the connector II 1420. By rotating the rotary cylinder I 1417, the rotary cylinder II 1419 and the drilling mechanism 142 connected to the rotary cylinder II 1419 are driven to swing around the rotation center of the rotary cylinder I 1417; by rotating the rotary cylinder II 1419, the drilling mechanism 142 is driven to swing around the rotation center of the rotary cylinder II 1419; by extending and retracting the drilling slide swing cylinder 1427, the pitch angle of the drilling mechanism 142 can be adjusted.

[0089] When the drilling mechanism 142 adopts scheme A, the drilling frame 1423 is rotatably mounted on the connector II 1420, and a drilling frame swing cylinder is provided between the drilling frame 1423 and the connector II 1420.

[0090] In this embodiment, the drilling device 14b installed on the tunnel / excavation equipment 1 is structurally similar to the drilling device 14a installed on the transfer belt conveyor 2. When the drilling device 14a (with a rotary cylinder installed between the boom front end and the drilling mechanism) is used, it can only be used to create drill-and-blast boreholes (the center line of the drilling mechanism 142 is parallel to the axis of the rotary cylinder Ⅲ1416) or only to provide anchor bolt support for the surrounding rock of the tunnel / excavation (the center line of the drilling mechanism 142 is perpendicular to the axis of the rotary cylinder Ⅲ1416), and cannot be used for both creating drill-and-blast boreholes and providing anchor bolt support for the surrounding rock of the tunnel / excavation. When the drilling device 14b (with two rotary cylinders installed between the boom front end and the drilling mechanism) is used, it can be used for both creating drill-and-blast boreholes and providing anchor bolt support for the surrounding rock of the tunnel / excavation.

[0091] Combination Figure 2 , Figure 6 and Figure 10 The rear end of the boom 1413 of the drilling device 14b is movably mounted on the lifting seat 135 of the boom sliding mechanism 13, with its front end swinging in both vertical and horizontal dimensions. The longitudinally movable front end of the boom 1413 is movably connected to the drilling mechanism 142. In this way, the boom 1413 can move with the longitudinal movement of the boom sliding mechanism's boom slide 134 and rise and fall with the rise and fall of the lifting seat 135. This not only solves the problem of blind spots in the drilling device caused by placing the drilling device on both sides of the equipment chassis and the rock cutting mechanism at the front of the chassis, but also the problem of the drilling device touching the working face rock wall when the rock cutting mechanism is loading the foremost rock cutting. Furthermore, it can increase the forward and backward movement range of the drilling device 14b, so that the drilling device can more conveniently create blasting rock boreholes and carry out anchor bolt support operations over a larger area.

[0092] Of course, without the boom sliding mechanism 13, the rear end of the boom 1413 can be directly and movably connected to the chassis 11.

[0093] The power head 1422 configured in the drilling device 14b of the tunnel / excavation equipment 1 is a rock drilling machine, and the power head 1422 configured in the drilling device 14a of the transfer belt conveyor 2 is either a rock drilling machine or a hydraulic motor.

[0094] In summary, this utility model, based on the technical concept of systems engineering, creates a complete set of multifunctional tunnel / tunnel excavation equipment. It solves the prominent problems commonly found in current small-span tunnel / tunnel excavation construction, such as incomplete equipment functionality, unsuitability for the engineering conditions of small-span tunnel / tunnel construction, unreasonable functional allocation among supporting equipment, and inconvenient connection and disassembly between them. These problems result in low mechanization levels, heavy workloads for workers, and low work efficiency and construction speed. This new equipment can significantly improve the mechanization level, construction speed, and work efficiency of small-span tunnel / tunnel excavation based on the drill-and-blast method, while reducing labor intensity. It will undoubtedly significantly promote the advancement of small-span tunnel / tunnel excavation technology.

The protection scope of the present utility model is determined by the content of the claims. Any equivalent transformations based on the technical teachings of the present utility model are within the protection scope of the present utility model.
