Description

Technical Field

[0001] This utility model relates to the field of auxiliary support technology for rapid tunneling in coal mines; specifically, this utility model relates to an integrated tunneling and anchoring machine that combines an automatic mesh laying device, a water-penetrating drill, and a dust removal system. Background Technology

[0002] The integrated tunneling and anchoring machine is a new type of coal mining machinery product developed to adapt to rapid tunneling. It integrates cutting, loading, transportation, movement, anchoring, and dust suppression functions, enabling parallel tunneling and anchoring operations. It can be equipped with shuttle cars and other rapid tunneling equipment to achieve efficient coal roadway tunneling. The integrated tunneling and anchoring machine has a complex overall structure with numerous parts, and its size is limited by the space of the tunnel. This results in a dense arrangement of structural, hydraulic, and electrical components within a very limited available space. Currently, anchor mesh laying is achieved manually by lifting the mesh and then operating the drill frame to drive the anchor bolts. This method not only increases the labor intensity of workers but also reduces the tunneling efficiency of the integrated tunneling and anchoring machine. Due to the limited space between the cutting section and the temporary support of the integrated tunneling and anchoring machine, and the need for both to perform lifting and lowering movements, the water-penetrating drill and dust suppression system cannot be installed simultaneously between the cutting section and the temporary support. This interference leads to low dust concentration at the working face and a low system safety factor. Utility Model Content

[0003] In view of this, the present invention provides an integrated excavation and anchoring machine that combines an automatic net laying device, a water exploration drill, and a dust removal system, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0004] To achieve the aforementioned objectives, this utility model provides an integrated excavation and anchoring machine that combines an automatic net-laying device, a water-detecting drill, and a dust removal system. The integrated excavation and anchoring machine includes a cutting section, temporary support, and a left platform cover. The automatic net-laying device is installed on the temporary support, and the anchor net roll is placed inside the automatic net-laying device. The water-detecting drill is installed on the cutting section and is configured to slide and rotate horizontally on the cutting section. The dust removal system is installed on the left platform cover, and a space is provided between the dust removal system and the left platform cover for easy disassembly and maintenance.

[0005] In the aforementioned integrated excavation and anchoring machine that combines an automatic net laying device, a water-penetrating drill, and a dust removal system, the automatic net laying device may optionally include a net laying frame and a connecting plate. The net laying frame and the connecting plate are fixedly connected. The connecting plate is used to connect the net laying frame to a temporary support. The net laying frame is provided with a placement groove for placing anchor net rolls, and the anchor net rolls can rotate within the placement groove.

[0006] In the aforementioned integrated excavation and anchoring machine that combines an automatic mesh laying device, a water exploration drill, and a dust removal system, optionally, two connecting plates are fixedly installed on the side of the mesh laying frame facing the temporary support.

[0007] In the aforementioned integrated excavation and anchoring machine that combines an automatic net laying device, a water exploration drill, and a dust removal system, optionally, the net laying frame includes parallel crossbeams I and II, with the ends of crossbeams I and II connected by arc-shaped bending plates. Two chains are provided between crossbeams I and II, and the two chains are located between the two arc-shaped bending plates. The connecting plate is fixedly connected to crossbeam I.

[0008] In the aforementioned integrated excavation and anchoring machine that combines an automatic net-laying device, a water-penetrating drill, and a dust removal system, optionally, both crossbeam I and crossbeam II are equipped with chain hooks for suspending the ends of the chains.

[0009] In the aforementioned integrated excavation and anchoring machine that combines an automatic net-laying device, a water-penetrating drill, and a dust removal system, optionally, a rotatable circular tube is provided at the top of the crossbeam I.

[0010] In the aforementioned integrated excavation and anchoring machine that combines an automatic net-laying device, a water-exploring drill, and a dust removal system, the water-exploring drill may optionally include a screw sliding mechanism, a drilling rig assembly, and a rotary mechanism.

[0011] In the aforementioned integrated excavation and anchoring machine that combines an automatic net-laying device, a water-penetrating drill, and a dust removal system, the dust removal system may optionally include a dust collector, a ventilation duct assembly, and a connecting base plate. The front end of the dust collector is connected to the rear end of the ventilation duct assembly, the dust collector is connected to the connecting base plate, and the connecting base plate is connected to the left platform cover.

Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1 to 4As shown, a typical embodiment of this utility model provides a tunneling and anchoring integrated machine 1 that integrates an automatic net laying device 2, a water-detecting drill 3, and a dust removal system 4. The tunneling and anchoring integrated machine 1 includes a cutting section 5, a temporary support 6, and a left platform cover 7. The automatic net laying device 2 is installed on the temporary support 6, and the anchor net roll is placed inside the automatic net laying device 2. The water-detecting drill 3 is installed on the cutting section 5 and is configured to slide and rotate horizontally on the cutting section 5. The dust removal system 4 is installed on the left platform cover 7, and a space is left between the dust removal system 4 and the left platform cover 7 for easy maintenance by removing the cover plate.

[0022] In this embodiment, the automatic mesh laying device 2, the water exploration drill 3, and the dust removal system 4 are installed on the tunneling and anchoring machine 1. This not only enables automatic mesh laying but also allows for advanced drilling and dust removal operations, effectively protecting the health and safety of workers and significantly improving the support efficiency of the tunneling and anchoring machine 1. It also solves the problems of low overall tunneling efficiency, high labor intensity for workers, high dust concentration at the working face, and low system safety.

[0023] The automatic net laying device 2 includes a net laying frame and a connecting plate 2.1. The net laying frame and the connecting plate 2.1 are fixedly connected. The connecting plate 2.1 is used to connect the net laying frame to the temporary support 6. The net laying frame is provided with a placement groove for placing the anchor net roll. The anchor net roll can rotate in the placement groove.

[0024] Before the tunneling operation, the workers first place the anchor mesh roll in the placement slot inside the automatic mesh laying device 2, then pull out the mesh edge of the anchor mesh roll and place it on the top plate of the temporary support 6. The drilling frame is used to drive anchor rods to fix the mesh edge to the top plate. Finally, when the tunneling and anchoring machine 1 advances forward, it will drive the anchor mesh roll to automatically unfold, realizing automatic mesh laying across the entire cross section of the tunnel.

[0025] In a relatively specific embodiment, two connecting plates 2.1 are fixedly installed on the side of the wire mesh frame facing the temporary support 6. The temporary support 6 is provided with a reserved installation position for inserting the connecting plates 2.1, and the connecting plates 2.1 are bolted to the temporary support 6.

[0026] Furthermore, the aforementioned space frame includes parallel crossbeams I 2.2 and II 2.3, with their ends connected by arc-shaped bending plates 2.4. Two chains 2.5 are provided between crossbeams I 2.2 and II 2.3, and the two chains 2.5 are located between the two arc-shaped bending plates 2.4. A connecting plate 2.1 is fixedly connected to crossbeam I 2.2.

[0027] A placement groove is formed between crossbeam I 2.2, crossbeam II 2.3, and the curved plate 2.4, allowing the anchor mesh roll to be placed into the groove using a support. During the installation of the anchor mesh, the anchor mesh roll rotates within the placement groove.

[0028] By utilizing the compressibility and extensibility of the chain 2.5, the narrow space between the cutting section 5 of the tunneling and anchoring machine 1 and the temporary support 6 can be effectively utilized without affecting the lifting and lowering movements of the temporary support 6 and the cutting section 5.

[0029] Both crossbeams I 2.2 and II 2.3 are equipped with chain hooks 2.6 for suspending the ends of chains 2.5. The addition of chain hooks 2.6 makes it easier to assemble and disassemble chains 2.5, resulting in a simpler and more practical overall structure.

[0030] A rotatable circular tube 2.7 is installed at the top of the crossbeam I 2.2. When the automatic mesh laying device 2 of the tunneling and anchoring machine 1 is working, the miners stand on the operating platforms on both sides of the tunneling and anchoring machine 1 and place the pre-rolled anchor mesh roll into the automatic mesh laying device 2 installed on the temporary support 6. The arc-shaped bending plate 2.4 and the chain 2.5 stably place the anchor mesh roll in the automatic mesh laying device 2; the edge of the anchor mesh roll is pulled out tightly against the circular tube 2.7 and placed on the top plate of the temporary support 6, and the edge of the mesh is fixed to the top plate by drilling anchor rods; when the tunneling and anchoring machine 1 moves forward, it will drive the anchor mesh roll to automatically unfold, realizing automatic mesh laying across the entire cross section of the roadway. The arc shape of the circular tube 2.7 can reduce the friction between the anchor mesh roll and the automatic mesh laying device 2, facilitating the release and unfolding of the anchor mesh roll.

[0031] The anchor mesh selected by the automatic mesh laying device 2 is a high-toughness polyester mesh for coal mines. This mesh has high toughness, light weight, high tensile strength and strong corrosion resistance, and can well replace traditional metal welded mesh.

[0032] The water exploration drill 3 consists of a screw sliding mechanism 3.1, a drilling rig assembly 3.2, and a rotary mechanism 3.3. The drilling rig assembly 3.2 is mounted on the rotary mechanism 3.3, and the rotary mechanism 3.3 is mounted on the screw sliding mechanism 3.1. The screw sliding mechanism 3.1 is used to drive the rotary mechanism 3.3 to slide horizontally, and the rotary mechanism 3.3 is used to drive the drilling rig assembly 3.2 to rotate.

[0033] Coal miners remotely control the tunneling and anchoring machine 1. First, the cutting section 5 is lowered to a certain height, and then the water exploration drill 3 is slid along the screw to the front end of the cutting section 5 to carry out advanced drilling operations. After completing the water exploration operation and ensuring safety, the water exploration drill 3 is finally slid to the rear end of the cutting section 5.

[0034] The dust removal system 4 includes a dust collector 4.1, a duct assembly 4.2, and a connecting base plate 4.3. The front end of the dust collector 4.1 is connected to the rear end of the duct assembly 4.2, and the dust collector 4.1 is connected to the connecting base plate 4.3, which is connected to the left platform cover 7.

[0035] When tunneling operations are carried out, the dust removal system 4 is turned on, and the dust in the roadway is drawn into the dust collector 4.1 from the ventilation duct assembly 4.2, thereby keeping the dust concentration at the working face of the roadway low.

[0036] The dust removal system 4 is installed on the left platform cover 7 and the water drilling rig 3 is installed on the cutting section 5, which effectively solves the problem that the space between the cutting section 5 and the temporary support 6 of the tunneling and anchoring machine 1 is limited, making it impossible to install the dust removal system 4 and the water drilling rig 3 at the same time.

[0037] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
