Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of coal mine equipment, and in particular to a mining face advance tunnel support system. Background Art
[0002] Due to the influence of dynamic pressure, the tunnel ahead of the coal mine working face will be deformed and even damaged, and the support conditions of the tunnel will deteriorate to varying degrees. Strengthened support of the tunnel ahead is necessary. Traditional strengthening support methods include single pillar support and comprehensive mining support or combined support. However, the single pillar support method has low support strength, and the workload of supporting and removing single pillars is large, the labor intensity of workers is high, and the efficiency is low. When using comprehensive mining support or other combined support, the forward step distance of the support is small each time, and it can only move forward about one meter each time. Therefore, in the tunnel range of 30-50 meters ahead of the mining working face, comprehensive mining support or combined support is used for support. During the process of advancing the working face, it is inevitable to lower the support and support multiple times, which will cause repeated support to the tunnel roof. The roof rock layer will be aggravated by repeated stress increase and release, which is very unfavorable to maintaining the integrity of the tunnel surrounding rock. Coal mining requires a reasonable support method that can quickly and efficiently strengthen the support of the advance tunnel of the mining face without repeatedly supporting the roof.

[0008] Furthermore, the second adjustment part includes a second crosshead, a fourth cylinder and a fifth cylinder. One end of the second crosshead is hinged to the telescopic part, and the other end of the second crosshead is hinged to the manipulator. The fourth cylinder is installed on the telescopic part and drives the second crosshead to swing in the vertical direction. The fifth cylinder is installed on the second crosshead and drives the manipulator to swing in the horizontal direction.
[0009] Furthermore, the manipulator includes a support arm and at least two supporting claws arranged on the support arm, and the supporting claws have grooves for limiting cooperation with the intermediate bracket.
[0010] Furthermore, the intermediate support includes a support top beam, two end components, two telescopic cylinders and two column cylinders.

The front-end robotic arm, mounted on the front-end support device, is then operated to support the support beam of the intermediate support on the support transport vehicle. The intermediate support is then lifted so that it rests against the roadway roof. The intermediate support is then manipulated from its retracted state to its supporting state, and the support transport vehicle is then transported via a cableway to the rear-end support device. This completes the process of removing, transporting, and installing one intermediate support. This process eliminates the need to move all intermediate supports, eliminates repeated lowering and supporting operations at the same location, and prevents repeated support of the roadway roof, thus preventing further damage to the roof.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative work are within the scope of protection of the present invention.
[0033] like Figures 1 to 7 As shown, an embodiment of the present invention provides an advance tunnel support system for a mining working face, comprising a head-end support device 100, a tail-end support device 200, a plurality of intermediate supports 300, a head-end mechanical arm 400, a tail-end mechanical arm 500, a support transport vehicle 600, and a cableway 700. The head-end mechanical arm 400 is mounted on the head-end support device 100, the tail-end mechanical arm 500 is mounted on the tail-end support device 200, and the plurality of intermediate supports 300 are arranged between the head-end support device 100 and the tail-end support device 200. The intermediate supports 300 have a supporting state for supporting the tunnel roof and a retracted state for retracting the size. The two ends of the cableway 700 are respectively connected to the head-end support device 100 and the tail-end support device 200, and the bracket transport vehicle 600 is arranged on the cableway 700 so as to be movable back and forth; wherein, when the intermediate bracket 300 closest to the tail-end support device 200 is in a retracted state, the tail-end robotic arm 500 moves the intermediate bracket 300 to the bracket transport vehicle 600, and the bracket transport vehicle 600 transports the intermediate bracket 300 to the head-end robotic arm 400, and the head-end robotic arm 400 places the intermediate bracket 300 on the bracket transport vehicle 600 on the ground, and is located between the head-end support device 100 and other intermediate brackets 300.
[0034] With this solution, as the mining face advances, when the last intermediate support 300 at the rear end is to be removed, the rear end robotic arm 500 is operated to support the support top beam 310 of the last intermediate support 300 at the rear end. At this time, the intermediate support 300 is retracted from its supporting state to its retracted state. The rear end robotic arm 500 places the retracted intermediate support 300 on a support transport vehicle 600. The support transport vehicle 600, along with the intermediate support 300 placed on it, is then transported via a cableway 700 to the front end support device 100. The head-end robotic arm 400, mounted on the head-end support device 100, is then operated to support the support top beam 310 of the intermediate support 300 on the support transport vehicle 600. The intermediate support 300 is then lifted so that it is in close contact with the tunnel roof. The intermediate support 300 is then manipulated to transition from a retracted state to a supported state. The support transport vehicle 600 is then transported to the tail-end support device 200 via the cableway 700. This completes the mechanized removal, transport, and installation of one intermediate support 300. During this process, there is no need to move all the intermediate supports 300, and there is no repeated lowering and support of the same position. Consequently, the tunnel roof is not repeatedly supported, thus avoiding further damage to the roof.
[0035] like Figures 3 and 4 As shown, the head-end robotic arm 400 includes a first adjusting portion 410, a telescopic portion 420, a second adjusting portion 430 and a robotic arm 440 connected in sequence, wherein the first adjusting portion 410 is installed on the head-end supporting device 100, the first adjusting portion 410 is used to adjust the angle of the telescopic portion 420, the second adjusting portion 430 is used to adjust the angle of the robotic arm 440, and the robotic arm 440 is used to support the intermediate bracket 300.
[0036] The first adjustment part 410, telescopic part 420 and second adjustment part 430 of the head end robotic arm 400 can be telescoped and swung left and right, driving the robotic arm 440 to grab the middle bracket 300, making the movement of the robotic arm 440 more flexible and more convenient to dismantle and support the middle bracket 300.
[0037] like Figures 3 and 4 As shown, the first adjustment part 410 includes a first crosshead 411, a first cylinder 412 and a second cylinder 413. One end of the first crosshead 411 is hinged to the head end support device 100, and the other end of the first crosshead 411 is hinged to the telescopic part 420. The first cylinder 412 is installed on the head end support device 100 and drives the first crosshead 411 to swing in the horizontal direction. The second cylinder 413 is installed on the first crosshead 411 and drives the telescopic part 420 to swing in the vertical direction.
[0038] The first crosshead 411 connects the head end support device 100 and the telescopic part 420, the first oil cylinder 412 controls the first crosshead 411 to swing in the horizontal direction, and the second oil cylinder 413 controls the telescopic part 420 to swing in the vertical direction, so that the first adjustment part 410 can adjust the position of the manipulator 440.
[0039] like Figures 3 and 4 As shown, the telescopic part 420 includes a third oil cylinder 421 and a first arm 422 and a second arm 423 which are socketed with each other. The first arm 422 is connected to the first adjustment part 410, and the second arm 423 is connected to the second adjustment part 430. The two ends of the third oil cylinder 421 are respectively connected to the first arm 422 and the second adjustment part 430. The total socket length of the first arm 422 and the second arm 423 is adjusted by the telescopic movement of the third oil cylinder 421.
[0040] The first arm 422 and the second arm 423 are connected to each other. When the third cylinder 421 is extended, the total length of the connection between the first arm 422 and the second arm 423 increases. When the third cylinder 421 is retracted, the total length of the connection between the first arm 422 and the second arm 423 decreases, thereby realizing the extension and contraction of the head end robotic arm 400.
[0041] like Figures 3 and 4 As shown, the second adjustment part 430 includes a second crosshead 431, a fourth cylinder 432 and a fifth cylinder 433. One end of the second crosshead 431 is hinged to the telescopic part 420, and the other end of the second crosshead 431 is hinged to the manipulator 440. The fourth cylinder 432 is installed on the telescopic part 420 and drives the second crosshead 431 to swing in the vertical direction. The fifth cylinder 433 is installed on the second crosshead 431 and drives the manipulator 440 to swing in the horizontal direction.
[0042] The second crosshead 431 connects the first adjustment part 410 and the telescopic part 420, the fourth cylinder 432 controls the second crosshead 431 to swing in the vertical direction, and the fifth cylinder 433 controls the manipulator to swing in the horizontal direction. The second adjustment part 430 and the first adjustment part 410 together improve the flexibility of the head end manipulator 400.
[0043] like Figures 3 and 4 As shown, the manipulator 440 includes a support arm and at least two supporting claws provided on the support arm, and the supporting claws have grooves for limiting engagement with the intermediate bracket 300 .
[0044] In this way, the claws can hold the support top beam 310 of the intermediate bracket 300 and lift the intermediate bracket 300. The groove in the middle of the claws can cooperate with the intermediate bracket 300 to limit the intermediate bracket 300 on the claws to prevent the intermediate bracket 300 from moving during the lifting process.
[0045] like Figure 5As shown, the intermediate support 300 includes a support top beam 310, two end components 320, two telescopic cylinders 330 and two column cylinders 340. The two end components 320 are respectively inserted into the two ends of the support top beam 310. The two telescopic cylinders 330 are both installed on the support top beam 310. Each telescopic cylinder 330 drives an end component 320 to extend and retract relative to the support top beam 310. The two column cylinders 340 are respectively installed at the lower ends of the two end components 320. The column cylinders 340 are used to support the ground, and the support top beam 310 is used to support the tunnel roof.
[0046] When the last intermediate support 300 at the rear end is to be removed, the manipulator 440 holds the intermediate support 300, and the end member 320 is driven by the telescopic cylinder 330 to retract the support top beam 310. The column cylinder 340 also contracts. At this time, the intermediate support 300 is in a retracted state and no longer supports the roadway. The support transport vehicle 600 transports the intermediate support 300 to the head end support device 100. When the intermediate support 300 reaches the head end support device 100, the manipulator 440 lifts the intermediate support 300 so that its support top beam 310 is close to the roadway roof. At this time, the end member 320 is controlled to extend and the column cylinder 340 is extended. The intermediate support 300 supports the roadway at this location.
[0047] like Figure 5 As shown, the support transport vehicle 600 carries the support top beam 310. The underside of the support top beam 310 has two spaced-apart protrusions 311, which are used to engage with the support transport vehicle 600 in a limited position. In this arrangement, the protrusions 311 engage with the support transport vehicle 600 in a limited position, preventing the intermediate support 300 from moving perpendicular to the cableway 700, thereby ensuring smooth transportation of the intermediate support 300.
[0048] like Figure 1 As shown, there are two groups of cableways 700, and the support transport vehicle 600 includes a connecting beam 610, two walking beams 620 and two limiting structures 630. The two walking beams 620 are respectively coordinated with the two groups of cableways 700. The two ends of the connecting beam 610 are respectively connected to the two walking beams 620. The two limiting structures 630 are respectively arranged on the two walking beams 620. The grooves on the limiting structures 630 are used to accommodate the intermediate support 300.
[0049] The two traveling beams 620 are respectively coupled to the two sets of cableways 700, and the traveling beams 620 can move on the cableways 700. A limiting structure 630 is provided on the traveling beams 620, and a connecting beam 610 connects the two traveling beams 620 together. The limiting structure 630 can limit the position of the intermediate bracket 300 transported by the bracket transport vehicle 600, preventing the intermediate bracket 300 from shifting in the direction of the cableway 700, further improving the smoothness of the transportation of the intermediate bracket 300.
[0050] Furthermore, the mining face advance tunnel support system also includes a winch 800, which is mounted on the head end support device 100. The winch 800 drives the support transport vehicle 600 back and forth via a wire rope. This arrangement makes driving the support transport vehicle 600 with the winch 800 and wire rope more convenient, easier to maintain, and simpler to operate.
[0051] The head end support device 100 and the tail end support device 200 have the same structure, and the head end mechanical arm 400 and the tail end mechanical arm 500 have the same structure. The head end support device 100 can move as a whole in the tunnel, and the head end support device 100 supports the tunnel roof.
[0052] Optionally, the head-end support device 100 includes a main frame portion 110 and a sub-frame portion 120, both of which support the roadway roof. The main frame portion 110 and the sub-frame portion 120 can be respectively extended and retracted in the height direction, and the main frame portion 110 and the sub-frame portion 120 can move relative to each other in the horizontal direction to achieve the overall movement of the head-end support device 100. When the intermediate support 300 moves to the front of the head-end support device 100, the head-end support device 100 and the tail-end support device 200 move as a whole in the same direction, and then the intermediate support 300 moves, thereby achieving the movement of the entire mining face advance roadway support system.
[0053] Optionally, the main frame portion 110 includes two main frame bases 111, at least two main frame lifting columns 112 and a main frame top beam 113, at least two main frame lifting columns 112 are respectively installed on the two main frame bases 111, the main frame lifting columns 112 are connected to the main frame top beam 113, driving the main frame top beam 113 to rise and fall; the sub-frame portion 120 includes a sub-frame top beam 123, two sub-frame bases 121 and two sub-frame lifting columns 122, the two sub-frame lifting columns 122 are respectively installed on the two sub-frame bases 121, the two sub-frame lifting columns 122 are connected to the sub-frame top beam 123, driving the sub-frame top beam 123 to rise and fall.
[0054] When the main frame lifting columns 112 drive the main frame top beam 113 downward, the main frame will no longer support the tunnel roof, so that the main frame 110 can move. After the main frame 110 moves, the main frame lifting columns 112 drive the main frame top beam 113 upward to support the tunnel roof again. When the sub-frame lifting columns 122 drive the sub-frame top beam 123 downward, the sub-frame will no longer support the tunnel roof, so that the sub-frame 120 can move. After the sub-frame 120 moves, the sub-frame lifting columns 122 drive the sub-frame top beam 123 upward to support the tunnel roof again.
[0055] Optionally, the head end support device 100 also includes an upper spring steel plate 131, a lower spring steel plate 132 and a driving cylinder 133. One end of the upper spring steel plate 131 is connected to the upper part of the sub-frame 120, and the upper spring steel plate 131 slides into the upper slide of the upper part of the main frame 110. One end of the lower spring steel plate 132 is connected to the lower part of the sub-frame 120, and the lower spring steel plate 132 slides into the lower slide of the lower part of the main frame 110. The driving cylinder 133 is installed at the lower part of the main frame 110, and the driving cylinder 133 drives the sub-frame 120 to move relative to the main frame 110. Among them, the upper spring steel plate 131 and the lower spring steel plate 132 can be bent and deformed so that the main frame part 110 and the sub-frame part 120 can be raised and lowered respectively. The main frame part 110 and the sub-frame part 120 alternately support the tunnel roof, and then cooperate with the extension and contraction of the driving cylinder 133 to realize the alternating movement of the main frame part 110 and the sub-frame part 120, thereby realizing the overall movement of the head end support device 100.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
