[0036] like Figure 1-11 As shown, the novel fully mechanized mining face roadway advance support assembly disclosed in this utility model includes a belt conveyor roadway transfer machine on-board support, a track roadway gantry support 4, and a rack car 5. The belt conveyor roadway transfer machine on-board support includes a first frame 1, an intermediate frame 2, and a tail frame 3 symmetrically arranged on both sides of the transfer machine.
[0037] The first frame 1 includes two sets of first fixed supports 101 and two sets of first movable supports 102 arranged alternately, which can achieve coordinated support of fixation and adjustment during the roadway support process, and improve the stability and adaptability of the overall structure. The first fixed support 101 includes a first single telescopic column 1011. A sleeve 1012 is sleeved on the outer side of the bottom end of the first single telescopic column 1011. The sleeve 1012 plays a limiting and guiding role. A connecting plate 1013 is fixedly connected to its bottom end. The bottom end of the connecting plate 1013 is firmly connected to the frame of the transfer machine by welding, realizing the integrated structural support of the support system and the transfer equipment. A first crossbeam 1014 is connected to the top end of the first single telescopic column 1011 to bear the vertical load from the top plate and transfer it to the column.

[0041] The second crossbeam 1023 includes a second box beam 1025, the bottom end of the second box beam 1025 is connected to two second column caps 1026, the left side of the second box beam 1025 is welded with two second push cylinder connecting lugs 1027, and the second column caps 1026 are connected to the second single telescopic column 1021.
[0042] A push cylinder 103 is connected between the first push cylinder connecting ear 1018 and the second push cylinder connecting ear 1027. The push cylinder 103 is used to drive the relative movement between adjacent supports, realize the lateral adjustment function of the support as a whole, and facilitate the flexible fine adjustment of the roadway support according to the roadway deformation or the position of the transfer equipment, thereby improving the layout accuracy and on-site construction efficiency.
[0043] The first hinged top beam 1015 includes a third box beam 104 and a fourth box beam 1041 hinged from left to right. The two are connected by a hinged structure, which has a certain angle adjustment capability. It can flexibly adapt to the deformation of the roadway according to the undulation of the roof, and improve the adaptability of the support system to complex surrounding rock structures. The bottom ends of the third box beam 104 and the fourth box beam 1041 are respectively welded with first connecting ears 1042. The first connecting ears 1042 are connected to the first cross beam 1014 below by a pin, ensuring the continuity of the overall force path and providing a stable foundation for the forward extension structure. The right end of the fourth box beam 1041 is equipped with a first forward extension beam 1043. The first forward extension beam 1043 adopts a telescopic structure design and is equipped with a first hydraulic cylinder 1044 inside. The first hydraulic cylinder 1044 is used to drive the forward extension beam to perform forward or retraction actions. The first forward extension beam 1043 is slidably connected to the fourth box beam 1041 through the first hydraulic cylinder 1044.
[0044] The second hinged top beam 1024 includes a fifth box beam 105 and a sixth box beam 1051 hinged from left to right. The bottom ends of the fifth box beam 105 and the sixth box beam 1051 are welded with second connecting ears 1052. The second connecting ears 1052 are connected to the second crossbeam 1023. A second forward probing beam 1053 is installed at the right end of the sixth box beam 1051. A second hydraulic cylinder 1054 is provided inside the second forward probing beam 1053. The second forward probing beam 1053 is connected to the sixth box beam 1051 through the second hydraulic cylinder 1054. The working principle is the same as that of the first hinged top beam 1015.
[0045] The intermediate frame 2 structure does not include the front beam, and the rest of the structure is the same as the first frame 1 structure.
[0046] The tail frame 3 has the same structure as the head frame 1, and the orientation is symmetrical.
[0047] The working principle of the on-board support of the belt conveyor is as follows: the fixed support of the on-board support is welded and fixed to the conveyor through the sleeve 1012 and the connecting plate 1013. The movable support moves forward with the fixed support as the fulcrum. During the forward movement, the top plate is always supported by the support. One working cycle is as follows:
[0048] When the forward extension beam extends, the control valve group controls the single telescopic column to lower the movable support column. The hinged top beam of the movable support detaches from the top plate. The telescopic jack extends to drive the movable support forward. After the movable support is pushed into place, the control valve group controls the single telescopic column to raise the movable support. The hinged top beam of the movable support supports the top plate.
[0049] The control valve group controls the single telescopic column to lower the fixed support column, the hinged top beam of the fixed support is separated from the top plate, and controls the transfer machine height adjustment cylinder to raise the transfer machine body; controls the transfer self-moving cylinder, the belt conveyor tail self-moving cylinder, and the support upper pushing cylinder 103 to move in the same direction, so that the fixed support and the transfer machine move forward synchronously.
[0050] After the transfer machine is moved into place, control the transfer machine's height adjustment cylinder to bring the transfer machine to the ground, control the fixed support to rise, and make the hinged top beam of the fixed support support the top plate.
[0051] When the fixed support moves forward, the telescopic jack is simultaneously retracted. During the lifting operation, both the fixed support and the movable support are raised and lowered simultaneously to avoid jamming due to asynchronous operation.
[0052] The track haulage portal frame 4 includes a box-type top beam 401. Two first reinforcing plates 402 are horizontally connected to the bottom end of the box-type top beam 401. A column cap 403 is welded to the bottom end of each first reinforcing plate 402. A double telescopic column 404 is connected to the column cap 403. A column shoe 405 is connected to the bottom end of each double telescopic column 404, allowing the double telescopic column 404 to vertically support the roadway roof and floor. Second reinforcing plates 406 are welded to both sides of the box-type top beam 401. One end of each second reinforcing plate 406 is connected to one end of the first reinforcing plate 402. Jack hinge seats 407 are connected to the left and right sides of the box-type top beam 401. A jack 408 is connected to one side of each jack hinge seat 407, and a support seat 409 is connected to the other side of each jack 408.
[0053] In this utility model, the number of track duct portal supports 4 is determined according to the range of influence of the advance pressure. The upper part of the double telescopic column 404 is provided with an anti-tipping clamp. The anti-tipping clamp is connected to the anti-tipping link through a threaded connection and is connected to the anti-tipping clamp of the adjacent track duct portal support 4 through a turnbuckle. The anti-tipping measures are safe and reliable and the operation is flexible.
[0054] The rack carriage 5 includes a frame 501, with a robotic arm 502 connected to the upper end of the frame 501 and a drive device 503 at the bottom end of the frame 501. The frame 501 and the robotic arm 502 are connected via a rotating mechanism 504, which has bearings installed inside. The drive device 503 at the bottom end of the frame 501 causes the rotating mechanism 504 to perform circular motion. A lifting mechanism 507 is connected to the top end of the robotic arm 502, and a translation mechanism 505 is slidably connected to the lifting mechanism 507. A clamping mechanism 506 is connected to the top end of the translation mechanism 505. The translation mechanism 505 is used to move the clamping mechanism 506 to align it with the rail trough portal frame 4. Clamping jacks are provided on both sides of the clamping mechanism 506 to clamp the rail trough portal frame 4.
[0055] The working principle of the track roadway gantry support 4 and the rack car 5 is as follows: mark the installation position of the first set of track roadway gantry supports 4 on the roadway floor, arrange the hydraulic system in the advance support range, and install a set of control valves at the tail of the scraper conveyor.
[0056] After the first set of track roadway gantry supports 4 is transported to the position, rotate the track roadway gantry supports 4 perpendicular to the roadway direction, lift the track roadway gantry supports 4, and stop the fluid supply when the box-type roof beam 401 is about to contact the roadway roof. Use the rack car 5 and the translation mechanism 505 to finely adjust the box-type roof beam 401 to the predetermined installation position. Connect the hydraulic systems of the two double telescopic columns 404 to the preset hydraulic system of the roadway, and slowly supply fluid to the two double telescopic columns 404. During this period, the double telescopic columns 404 should be in a vertical state and the two column shoes 405 of the columns should be adjusted to match the pre-installation position. Supply fluid to the double telescopic columns 404 until the design pressure is reached.
[0057] Similarly, install the second set of track gantry brackets 4 into place, install anti-tipping rods between the corresponding two double telescopic columns 404, and adjust the tightness of the anti-tipping rods until all bracket installation work is completed.
[0058] During the cyclical operations of support withdrawal, transportation, and installation during the mining period, the rack car 5 is moved to the area below the track gantry support 4 that needs to be withdrawn. The lifting mechanism 507 is raised, and the clamping mechanism 506 with U-shaped support beam groove is moved to the box-type top beam 401 in the track gantry support 4 and clamped. The clamping jack is operated to make the clamping mechanism 506 firmly clamp the box-type top beam 401. The anti-tipping connecting rod between the double telescopic columns 404 is removed, and the two double telescopic columns 404 are retracted to their shortest length. The jack of the lifting mechanism 507 is retracted to gradually lower the height of the double telescopic columns 404. The liquid supply pipeline of the double telescopic columns 404 is removed. The rotating mechanism rotates the track gantry support 4 90° and then stops the liquid supply. The track gantry support 4 is transported to the pre-support installation position by the rack car 5, and at the same time, one section of the transport rack is removed.
[0059] After the track roadway gantry support 4 is transported to its position, rotate the track roadway gantry support 4 and lift it 90°. When the box-type roof beam 401 is about to contact the roadway roof, stop the hydraulic supply. Use the rack car 5 and the translation mechanism 505 jack to finely adjust the box-type roof beam 401 to the predetermined installation position. Connect the hydraulic systems of the two double telescopic columns 404 to the preset hydraulic system in the roadway. Slowly supply hydraulic fluid to the two double telescopic columns 404. During this period, the double telescopic columns 404 must be in a vertical position and the two column shoes of the columns must be adjusted to match the pre-installation position. Supply hydraulic fluid to the columns until the design pressure is reached. Repeat this cycle of support retraction, transportation, and installation.
[0060] During the coal mining process in the fully mechanized mining face, after the coal mining machine has mined the coal at the front end, the scraper conveyor transports the coal to the transfer machine, and the coal mining machine continues to mine coal forward. At this time, the on-board support of the belt conveyor transfer machine moves forward to provide advance support. When the coal mining machine runs from the tail of the scraper conveyor to the head of the machine, the track roadway gantry support 4 and the rack car 5 work together.
