Description

Technical Field

[0001] This invention belongs to the field of coal mining technology, and specifically relates to a rapid tunneling device for coal mining roadways that integrates drilling and pressure excavation. Background Technology

[0002] Coal, as the main energy source in my country's energy system, plays a crucial role in ensuring national energy security and promoting steady economic development. However, with the continuous deepening of coal mining and the expansion of tunnel excavation, the drawbacks of traditional tunneling technologies have become increasingly apparent. Their low efficiency and poor safety not only fail to meet the construction needs of high-yield and high-efficiency mines but also lead to increasingly strained mining and excavation processes, significantly increasing safety risks. At the same time, the inherent limitations of traditional tunneling technologies are becoming more and more obvious. The complex procedures and low level of automation result in a significant consumption of manpower and time during the tunneling process; the limited support effect makes it difficult to effectively cope with the surrounding rock pressure under complex geological conditions, threatening tunnel stability; and the lack of monitoring methods makes it impossible to accurately grasp various parameters during the tunneling process in real time, creating hidden dangers for safe operations.

[0003] In practical applications of existing integrated drilling and tunneling coal mining roadway rapid excavation devices, coal seams are typically crushed using a coal cutting drum, with the bottom feed hopper used for coal collection and transportation. However, during the coal cutting drum excavation process, due to factors such as compression and impact, some coal seams collapse in the form of large chunks and accumulate at the bottom of the feed hopper. Because these coal chunks are not crushed and are large in size, they are difficult to transport smoothly through the feed hopper, easily causing blockages. This not only affects the normal collection of coal chunks but also hinders the advancement of the excavation device, leading to a significant reduction in work efficiency. If a fixed crushing device is installed on the device, it needs to be installed at a forward position to crush coal chunks as needed. However, this would expose the device directly to the coal chunk falling area, frequently subjecting it to the large impact force generated by falling coal chunks. Prolonged exposure to such harsh working conditions would easily cause the device to break down quickly, affecting normal operation and reducing overall work efficiency.

[0004] Therefore, it is necessary to invent a rapid tunneling device for coal mining roadways that integrates drilling, pressure and tunneling to solve the above problems. It has the ability to crush and process the falling coal blocks appropriately according to their size, effectively avoids the problem of clogging the feed hopper, and significantly improves the convenience and efficiency of tunneling operations.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. This invention utilizes the combined use of a feeding auxiliary control mechanism and a feeding crushing mechanism. The feeding auxiliary control mechanism drives the positioning screw to rotate via a first drive motor, thereby controlling the movement of the feeding crushing mechanism. The feeding crushing mechanism, through the rapid impact of the impact cylinder and hammer, can promptly crush large coal pieces, avoiding hopper blockage and ensuring smooth coal transport. Simultaneously, a second drive motor rotates the rotating seat, further improving the crushing effect.

Furthermore, the feeding crushing mechanism is retracted when the tunneling device moves, protecting the normal operation of the equipment.

[0019] 2. This invention uses a servo motor to drive an adjusting screw in the telescopic feeding mechanism, which causes the telescopic hopper to slide along the outer wall of the feeding hopper.

[0020] 3. The present invention effectively prevents large coal blocks from entering the hopper through the design of the positioning protective plate and the lifting protective plate, and also effectively blocks the direct impact of falling coal blocks on the equipment. During the movement of the tunneling device, it protects key components such as the feeding crushing mechanism from damage, reduces the equipment failure rate, and improves operational safety. The setting of the reset spring further enhances the stability and reliability of the protective mechanism.

Second telescopic control rods 107 are rotatably connected to both ends of the bottom of the undulating control frame 106. One end of each of the two second telescopic control rods 107 is rotatably connected to both ends of the bottom of the undulating control frame 106.

[0040] One end of the tunneling control base 101 is rotatably connected to a feed hopper 111. Both ends of one side of the tunneling control base 101 are rotatably connected to third telescopic control rods 109. One end of each of the two third telescopic control rods 109 is rotatably connected to one end of the feed hopper 111. Both sides of the top of the feed hopper 111 are rotatably connected to feed wheels 114. Both ends of the inner wall of the feed hopper 111 are fixedly connected to control motors 113. The output ends of the two control motors 113 are fixedly connected to the middle position of the two feed wheels 114. The bottom of the tunneling control base 101 at the middle position is connected to a transport mechanism 110. The top position of the transport mechanism 110 corresponds to the discharge port position of the feed hopper 111.

[0041] One end of the feed hopper 111 is provided with an inclined groove 112, the bottom end of the inclined groove 112 is in sliding contact with the top end of the telescopic hopper 201, one end of the telescopic hopper 201 is provided with a guide groove 202, both sides of the inner wall of the telescopic hopper 201 are fixedly connected with positioning strips 203, and the top ends of both sides of the feed hopper 111 are provided with positioning grooves 115, and the outer walls of the two positioning strips 203 are slidably connected to the inner walls of the two positioning grooves 115 respectively.

[0042] When the integrated drilling and tunneling coal mining roadway rapid tunneling device is needed, the first telescopic control rod 105, the second telescopic control rod 107, the third telescopic control rod 109 and the track wheel 102 are controlled by the control room 103 to enable the rapid tunneling device to mine coal and move. The collected coal blocks are collected by the rotation of the feed wheel 114. After collection by the feed hopper 111, the coal blocks are transported to the rear transport equipment by the transport mechanism 110.

[0043] In one specific embodiment of the present invention, the telescopic feeding mechanism 2 includes a telescopic hopper 201 that slides on the outer wall of the feeding hopper 111. A moving block 207 is fixedly connected to one end of the top middle position of the telescopic hopper 201. A control seat 204 is fixedly connected to the middle position of the feeding hopper 111. An adjusting screw 205 is rotatably connected to the middle position of the control seat 204. One end of the outer wall of the adjusting screw 205 is threadedly connected to the middle position of the moving block 207. A servo motor 206 is fixedly connected to one side of the feeding hopper 111. The output end of the servo motor 206 is fixedly connected to one end of the adjusting screw 205. The output end of the second drive motor 406 is rotatably connected to the connecting seat 401.

[0044] The servo motor 206, fixed to the inner wall of the feed hopper 111, operates, causing the adjusting screw 205, fixed to the output end of the servo motor 206, to rotate along the inner wall of the control seat 204. This causes the moving block 207, threaded onto the outer wall of the adjusting screw 205, to drive the telescopic hopper 201 to move along the outer wall of the feed hopper 111. The positioning strip 203, fixed to the inner wall of the telescopic hopper 201, is slidably connected to the positioning grooves 115 on both sides of the outer wall of the feed hopper 111, allowing the telescopic hopper 201 to continuously reciprocate along the feed hopper 111. This allows the coal blocks in front of the tunneling device to be collected in batches into the feed hopper 111, and the feed wheel 114 assists in stable transportation, avoiding the risk of excessive accumulation at one time and improving the coal collection efficiency.

[0045] In one specific embodiment of the present invention, the feeding auxiliary control mechanism 3 includes a positioning seat 301, a positioning screw 302 rotatably connected to the middle position of the positioning seat 301, movable seats 303 threadedly connected to both ends of the outer wall of the positioning screw 302, connecting rods 304 rotatably connected to the bottom ends of the two movable seats 303, one end of the two connecting rods 304 rotatably connected to each other, and a feeding crushing mechanism 4 rotatably connected to the two connecting rods 304. A first positioning helical gear 305 is fixedly connected to the middle position of the outer wall of the positioning screw 302, a limiting seat 306 is fixedly connected to the middle position of one side of the positioning seat 301, a second positioning helical gear 307 is rotatably connected to one side of the limiting seat 306, the tooth surface of the first positioning helical gear 305 meshes with the tooth surface of the second positioning helical gear 307, and a first drive motor 308 is fixedly connected to the other side of the limiting seat 306. The output end of the first drive motor 308 is fixedly connected to the center position of the second positioning helical gear 307.

[0046] The output end of the first drive motor 308, fixed to one side of the limiting seat 306, drives the second positioning helical gear 307 to rotate. The teeth of the second positioning helical gear 307 mesh with the teeth of the first positioning helical gear 305, causing the first positioning helical gear 305 to drive the positioning screw 302 to rotate. This causes the positioning screw 302 to rotate around its own axis within the positioning seat 301. The movable seats 303, threaded to both ends of the outer wall of the positioning screw 302, move in opposite directions, causing the rotational connection between the bottom ends of the two movable seats 303 to... The connecting rod 304 drives the connecting seat 401 to move. When it is necessary to crush larger coal blocks, the two moving seats 303 are controlled to move towards each other, so that the two connecting rods 304 drive the feeding crushing mechanism 4 to move to the corresponding position to crush the coal blocks. After crushing, if it is necessary to move forward stably, the two moving seats 303 are controlled to move in opposite directions, so that the two connecting rods 304 control the feeding crushing mechanism 4 to move to the position closest to the feed hopper 111, protecting the feeding crushing mechanism 4 from the potential danger of being crushed and increasing the flexibility of coal block crushing.

[0047] In one specific embodiment of the present invention, the feeding crushing mechanism 4 includes a connecting seat 401, a positioning sleeve fixedly connected to the middle position of the connecting seat 401, one end of each of the two connecting rods 304 being rotatably connected to the outer wall of the positioning sleeve, a rotating seat 402 rotatably connected to the bottom end of the connecting seat 401, a mounting seat 403 fixedly connected to one side of the rotating seat 402, an impact cylinder 404 fixedly connected to the bottom end of the mounting seat 403, a hammer 405 fixedly connected to the output end of the impact cylinder 404, and a second drive motor 406 fixedly connected to the top end of the connecting seat 401. The output end of the second drive motor 406 passes through the positioning sleeve and is fixedly connected to the middle position of the top of the rotating seat 402.

A second fixed seat 409 is fixedly connected to the middle position of the bottom of the positioning seat 301. One end of the outer wall of the limit rod 408 is inserted and connected to the middle position of the second fixed seat 409. A limit block 410 is fixedly connected to one end of the limit rod 408.

[0049] The impact cylinder 404, fixed to one side of the mounting base 403, drives the hammer 405 to impact larger coal blocks. The output of the second drive motor 406, fixed to the top of the connecting base 401, drives the rotating base 402 and the mounting base 403 to rotate. The connecting rod 304 controls the movement of the connecting base 401, allowing larger coal blocks to be crushed quickly and thoroughly, avoiding the potential blockage of the feed hopper 111. At the same time, the limiting rod 408, fixed to one side of the first fixed base 407, is inserted into the second fixed base 409, fixed to the bottom of the positioning base 301, so that the movement of the connecting base 401 is stably controlled, increasing the stability of the crushing operation.

[0050] The feeding protection mechanism 5 includes a positioning protection plate 501 fixed to one side of the positioning seat 301, a lifting protection plate 502 slidably connected to one side of the positioning protection plate 501, a balance bar 503 fixedly connected to the middle position of the bottom of the lifting protection plate 502, one side of the balance bar 503 slidably connected to one side of the positioning protection plate 501, four mounting blocks 504 fixedly connected to one side of the positioning protection plate 501, four positioning rods 505 fixedly connected to one end of the bottom of the lifting protection plate 502, a return spring 506 inserted through one end of the outer wall of each of the four positioning rods 505, the other end of the outer wall of each of the four positioning rods 505 being inserted through one end of each of the four mounting blocks 504, and a positioning block 507 fixedly connected to the bottom end of each of the four positioning rods 505.

[0051] Positioning of the positioning protective plate 501 fixed to one side of the positioning seat 301 allows the lifting protective plate 502 to move stably along the positioning protective plate 501. The positioning rod 505 fixed to the bottom of the lifting protective plate 502 is inserted and connected to the mounting block 504 fixed to one side of the positioning protective plate 501. The elastic deformation of the return spring 506 inserted into the outer wall of the positioning rod 505 and the positioning of the positioning block 507 ensure that the lifting protective plate 502 is stable at the highest point without external force, thus blocking the coal pile and preventing large coal blocks from blocking the feed hopper 111. It also prevents the coal blocks from being collected too quickly and overflowing into the feed hopper 111, thus improving the coal collection efficiency. The return spring 506 prevents hard damage when the coal mining drum 108 is raised and lowered.
