Description

Technical Field

[0001] The utility model relates to the technical field of tunnel boring machines, in particular to a tunnel boring machine rear-mounted slag discharge device and a tunnel boring machine. Background Art

[0002] Currently, coal seams with inclinations between 25° and 45° are considered inclined coal seams. Cutting and tunneling in inclined coal seams typically involve pilot tunneling and wall expansion. To facilitate slag removal, tunneling is typically performed from bottom to top using blasting, with manual slag removal using scraper conveyors or other mechanical assistance. This tunneling method involves blasting, carries significant safety risks, is labor-intensive, and has a low single-advance performance. Based on a 1m cycle, the average daily tunneling progress is 4m to 6m. The climbing capacity of a cantilevered roadheader (TBM) is generally ≤±18°. When used for pilot tunneling and wall expansion in coal seams with inclinations between 25° and 45°, the only option is a top-down approach. The TBM advances downward head-on, right next to the working face, and must be assisted by a winch for upward traction. At present, for inclined coal seams, a cantilever tunneling machine can be used to construct the inclined coal seam cutting and excavation working face, and a bridge-type transfer machine can be used in conjunction with the tunneling machine and scraper conveyor to continuously discharge slag.

[0003] However, when the above-mentioned winch-assisted traction and bridge-type transfer machine are used for material transportation, during the traction process of the winch traction rope, the winch wire rope will interfere with the bridge-type transfer machine, often causing scratches and damaging the bridge-type transfer machine, or as the inclination of the coal seam increases, the material is prone to slide during the upward transportation process, making the bridge-type transfer machine unusable.

[0045] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] like Figures 1 to 2 As shown, the first embodiment of the present invention provides a slag discharge device for a roadheader. The device comprises a traction frame 10, a connecting base 30, a first rotating shaft 41, a material guide 50, and a first rotating sleeve 60. The traction frame 10 is connected to the traction beam 20 of the roadheader, which is in turn connected to the traction rope of the roadheader's winch. The connecting base 30 is mounted on one side of the traction frame 10, and the first rotating shaft 41 is disposed on the connecting base 30, extending in the direction of the traction rope. The material guide member 50 and the first rotating sleeve 60 are connected to each other. The first rotating sleeve 60 is sleeved on the first rotating shaft 41 and rotates relative to the first rotating shaft 41. The material guide member 50 has a material guide trough. The extension direction of the material guide trough is set at a preset angle to the extension direction of the first rotating shaft 41. The material guide trough has a feed port 51 and a discharge port 52 that are relatively set. The discharge port 52 is located below the feed port 51. The feed port 51 is connected to the discharge part of the tunneling machine. The discharge port 52 is located on one side of the traction frame 10.

[0047] The slag discharge device provided at the rear of the roadheader of this embodiment is provided with a material guide 50, which is rotatably arranged on one side of the traction frame 10 along the first rotating shaft 41. Since the first rotating shaft 41 extends in the direction of extension of the traction rope, and the material discharge port 52 is also located on one side of the traction frame 10, when discharging material through the material discharge port 52 of the material guide 50, the movement of the material guide 50 will not interfere with the traction rope, and the traction rope will not scratch the material guide 50. At the same time, the material at the material discharge port 52 will not interfere with the traction rope, thus facilitating the discharge of material through the material guide 50. Therefore, the slag discharge device provided at the rear of the roadheader of this invention can solve the problem in the prior art that when a winch is used for traction, the traction rope of the winch is easily interfered with by the bridge-type transfer machine, thus making the equipment easily damaged. In addition, since a bridge-type transfer machine is not used, the problem that as the inclination of the coal seam increases, the material is easily slipped during upward transportation, making the bridge-type transfer machine unusable, can also be solved.

[0048] Specifically, because the feed port 51 of the guide member 50 is docked with the discharge portion of the tunnel boring machine, when the discharge portion of the tunnel boring machine discharges material, the material will fall into the guide trough through the feed port 51. Due to the action of the material, the guide member 50 will rotate along the first rotating shaft 41 at a certain angle. Subsequently, due to the gravity of the material, the guide member 50 will continue to rotate and discharge the material through the discharge port 52 located on the side of the traction frame 10. The above-mentioned discharge process utilizes the gravity of the material combined with the rotation of the guide member 50. Under the action of gravity, the material will drive the guide member 50 to rotate adaptively, so that the material in the guide trough can be smoothly discharged through the discharge port 52 under the action of gravity. The rotation of the guide member 50 will not interfere with the traction rope. The structure is simple, easy to operate, and the discharge is stable. It will not interfere with the traction rope of the winch. Specifically, the material guiding process of the guide member 50 can be understood as the self-sliding discharge of material. Specifically, the material can be coal slag.

[0049] Specifically, the material guide member 50 is swung up and down through the first rotating shaft 41 to better adapt to the gravity of the material, and the material guide member 50 is driven to swing up and down under the action of the gravity of the material, thereby facilitating better discharge of the material.

[0050] Specifically, the material guiding member 50 is welded to the first rotating sleeve 60 .

[0051] In this embodiment, the rear-mounted slag discharge device for the roadheader further includes a second rotating shaft 42 and a second rotating sleeve 70. The second rotating shaft 42 is fixedly connected to the first rotating shaft 41 and is arranged at a preset angle relative to the first rotating shaft 41. The second rotating sleeve 70 is fixedly connected to the connecting seat 30 and is located on one side of the connecting seat 30. The second rotating shaft 42 is rotatably disposed within the second rotating sleeve 70. The first rotating shaft 41 is mounted on the connecting seat 30 via the second rotating shaft 42 and the second rotating sleeve 70. This structural arrangement facilitates the material guide 50 to achieve a certain range of left-right swinging on one side of the traction frame 10, thereby better adapting to the material feed direction and facilitating the receipt of material flowing out of the discharge portion of the roadheader.

[0052] Specifically, the material guide member 50 can swing in the left and right directions through the second rotating shaft 42 , and this left and right swing is also adapted to the feeding direction of the material entering through the feeding port 51 .

[0053] Specifically, the traction frame 10 includes a frame body 11 and a connecting bar 12. The frame body 11 includes a first connecting plate 111, a second connecting plate 112, and a third connecting plate 113 connected in sequence. The first connecting plate 111 and the third connecting plate 113 are arranged opposite each other and spaced apart along the extension direction of the traction rope. The first connecting plate 111, the second connecting plate 112, and the third connecting plate 113 form an avoidance groove. The two ends of the connecting bar 12 are respectively connected to the first connecting plate 111 and the third connecting plate 113, and the connecting bar 12 extends along the extension direction of the traction rope. The connecting seat 30 is installed on the connecting bar 12; in the extension direction of the connecting bar 12, the length of the connecting bar 12 is greater than the length of the material guide 50, so that the material guide 50 is tilted and arranged between the first connecting plate 111 and the second connecting plate 112. Such a structural setting can facilitate a certain restriction on the left and right swing of the material guide member 50, so as to limit the material guide member 50 between the first connecting plate 111 and the second connecting plate 112, and avoid the material guide member 50 from interfering with the traction rope or winch after exceeding the first connecting plate 111 and the second connecting plate 112, so as to better avoid the traction rope from scratching the material guide member 50, facilitate effective protection of the material guide member 50, and facilitate smooth material guidance through the material guide member 50.

[0054] Specifically, the connecting base 30 includes a fixed plate 31 and at least two U-shaped connectors 32. A first rotating shaft 41 is disposed on the fixed plate 31, which is mounted on the connecting bar 12 and extends along the connecting bar 12. The at least two U-shaped connectors 32 are spaced apart along the extending direction of the fixed plate 31. Both ends of each U-shaped connector 32 are connected to the fixed plate 31 and surround at least a portion of the outer edge of the connecting bar 12. This structural arrangement improves the connection stability of the connecting base 30, thereby facilitating the stable positioning of the material guide 50 on one side of the traction frame 10, thereby better avoiding the traction rope.

[0055] In this embodiment, a stopper slope is provided on one side of the first connecting plate 111 near the material guide 50. The stopper slope mates with the bottom surface 53 of the material guide 50 and is configured to abut against the bottom surface 53 of the material guide 50. Specifically, when the material guide 50 is in a normal position, the bottom surface 53 of the material guide 50 abuts against the stopper slope, thereby placing the material guide 50 in an inclined position, which facilitates material discharge. When material enters the feed port 51, the material guide 50 partially tilts upward. Subsequently, as the material's gravity acts, the material guide 50 partially tilts downward, thereby facilitating smooth material discharge from the discharge port 52.

[0056] Specifically, the traction frame 10 is adjustably mounted on the traction beam 20. Both the traction frame 10 and the traction beam 20 extend along the extension direction of the traction rope. The traction frame 10 has a first installation position and a second installation position. When the traction frame 10 is in the first installation position, the material guide 50 is rotatably mounted on one side of the traction beam 20. When the traction frame 10 is in the second installation position, the material guide 50 is rotatably mounted on the other side of the traction beam 20. This structural arrangement facilitates adaptive adjustment of the installation position of the material guide 50 according to actual needs, allowing the material guide 50 to be positioned in either the first or second installation position, thereby facilitating material discharge from the discharge port 52 on one side of the traction beam 20 or the other side of the traction beam 20. Specifically, when the traction frame 10 is in the first installation position, the traction frame 10 and the traction beam 20 need to be locked to ensure that the traction frame 10 remains in the first installation position and prevents positional displacement due to the material guiding operation of the material guide 50. When the traction frame 10 is in the second installation position, the traction frame 10 and the traction beam 20 need to be locked to ensure that the traction frame 10 is stably in the second installation position and will not be shifted due to the material guiding operation of the material guide 50.

[0057] In this embodiment, the traction frame 10 is rotatably mounted on the traction beam 20; the angular difference between the first mounting position and the second mounting position is 180°. This facilitates operation and enables stable switching between the first mounting position and the second mounting position.

[0058] Specifically, the traction frame 10 is rotatably disposed on the traction beam 20 via a pin shaft 100 .

[0059] Specifically, the rear-mounted slag discharge device of the roadheader further includes a protective cover 80, which is connected to the material guide 50 and is positioned at the discharge port 52 and extends beyond the discharge port 52. This facilitates the guidance of material at the discharge port 52 for smooth discharge. Specifically, the protective cover 80 can be made of soft rubber to better support and guide the material, facilitating discharge.

[0060] In order to better convey the materials in the guide trough, a conveyor belt structure can be added in the guide trough.

[0061] Specifically, a small scraper conveyor 90 driven by a hydraulic motor or a micro belt conveyor driven by an electric roller is set in the material guide trough, and its length is controlled at 2 to 3 meters. One end of the small scraper conveyor 90 or the micro belt conveyor is overlapped with the discharge part of the tunneling machine, and the other end is overlapped with the scraper conveyor 90 for slag discharge. The slag dropping position of the small scraper conveyor 90 or the micro belt conveyor is adjusted by using an oil cylinder.

[0062] In this embodiment, the rear-mounted slag discharge device of the roadheader further includes a scraper conveyor 90, which is disposed on one side of the traction frame 10, with the discharge port 52 facing the scraper conveyor 90. This facilitates the conveyance of materials by the scraper conveyor 90. Specifically, the discharge port 52 can be positioned toward the corresponding side of the traction frame 10 on which the scraper conveyor 90 is disposed, thereby facilitating smooth material conveyance by the scraper conveyor 90.

[0063] A second embodiment of the present invention provides a roadheader, comprising a main body, a winch, and the rear-mounted slag discharge device provided in the above-described embodiment. The winch is mounted on the main body. The rear-mounted slag discharge device is mounted on the main body, spaced apart from the winch. The discharge port 52 of the rear-mounted slag discharge device and the scraper conveyor 90 of the rear-mounted slag discharge device are both located on one side of the winch's traction rope. This structural arrangement prevents interference between the winch's traction rope and the material guide 50 of the rear-mounted slag discharge device, preventing the traction rope from scratching the material guide 50, while also ensuring smooth material feeding by the material guide 50.

[0064] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: a slag discharge device is provided at the rear of the tunnel boring machine, which adjusts the slag discharge angle and slag drop position by swinging the material guide member up and down and rotating left and right, and realizes 180° adjustment of the guide chute by the traction frame pin. The slag is discharged by self-flowing, and the slag discharge angle and slag drop position of the guide chute are adjustable. There is no need to consider the angle of the belt conveyor lifting the material. This fundamentally eliminates the bridge-type transfer machine from falling and avoids the equipment being damaged by the winch wire rope pulling the tunnel boring machine. No power is required, the equipment investment is small, and the tunnel boring machine is not affected by the slag discharge device at the rear, which is more convenient to operate. It is suitable for inclined coal seam cutting and excavation working faces with different conditions, and can directly change the tunneling construction method for large-angle cutting. In addition, the slag discharge device at the rear of the tunnel boring machine in this application also has application value in steeply inclined coal seam cutting and excavation working faces.
