Description

Technical Field

[0001] This invention relates to the technical field of roadway maintenance equipment, specifically a roadway maintenance machine for coal mines. Background Technology

[0002] Coal mine roadways are underground tunnel networks formed during mining operations. As the core passages in the mining production chain, roadways primarily serve five needs: ore transportation, worker access, ventilation and heat dissipation, drainage and waste disposal, and equipment installation. For example, main haulage roadways need to accommodate tracks and ore transport vehicles, while ventilation roadways, through their rational layout, ensure underground air circulation. During use, coal mine roadways are prone to protruding ore bodies due to changes in excavation stress, thus requiring regular maintenance.

[0003] Chinese patent document CN105714865B discloses a roadway repair machine for coal mines, belonging to the field of coal mining. It includes a vehicle body and an actuator. The vehicle body includes a traveling device and a frame mounted above the traveling device. The actuator includes a boom, a forearm, and a bucket. One end of the boom is mounted on the front end of the frame via a lifting mechanism, and the boom is connected to the forearm. The other end of the forearm is equipped with a bucket. The lifting mechanism includes two vertically mounted guide rails on the front end of the frame and a slider. The slider engages with U-shaped grooves on the guide rails via two vertically mounted guide bars on one side of the slider. The slider is connected to the frame via a vertically mounted hydraulic cylinder. The boom is mounted on the side of the slider away from the guide rails via an intermediate mechanism. Furthermore, existing patent solutions, such as CN111764912A, allow the bucket and breaker hammer at the front end of the working device to rotate 360°, making roadway repair more convenient. The above invention has advantages such as wide application range and good repair effect.

[0004] The plan still has some shortcomings in its implementation: 1. During the repair process, the soil and gravel produced by the breakage often fall directly to the surrounding area, making it necessary to clean up the accumulated debris first when carrying out subsequent repair work. This results in low work efficiency, and the fallen debris, due to its varying sizes, occupies a large space and is difficult to clean. 2. It is difficult to select the appropriate drill pipe according to actual needs, which affects work efficiency; 3. It is difficult to collect the gravel and debris on the surface of the tunnel, which can easily affect subsequent maintenance work. Summary of the Invention

Detailed Implementation

[0019] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0020] Please see Figure 1-7 A coal mine roadway repair machine includes a mobile track 1 and a guard plate 9 fixed above the mobile track 1. An operator's cab 2 and a robotic arm 5 are installed on the guard plate 9. A storage box 7 is supported between the mobile tracks 1. A receiving mechanism 4 is connected to the end of the guard plate 9. The receiving mechanism 4 is configured to cooperate with the storage box 7. A repair mechanism 6 is installed at the end of the robotic arm 5. The repair mechanism 6 is movably located above the receiving mechanism 4. An adjustment mechanism 8 is provided between the mobile tracks 1. A ground shovel 3 is connected to the adjustment mechanism 8. The ground shovel 3 is configured to cooperate with the receiving mechanism 4.

[0021] The mobile track 1 is driven below the guard plate 9, which facilitates the movement of the tunnel repair machine. A receiving platform is set between the mobile tracks 1 to facilitate the placement of storage boxes 7 and other items.

[0022] In practical use, the operating room 2 facilitates safe operation for staff. The receiving mechanism 4 receives the gravel generated during the repair process and stores it in the storage box 7. The storage box 7 reduces the space occupied by gravel, allowing for more gravel storage and reducing the need for waste disposal. The repair mechanism 6 allows for the selection of different sized repair drill bits to suit various tunnel conditions. The adjusting mechanism 8 facilitates the transfer of material shoveled by the shovel 3 to the receiving mechanism 4, which then transfers it to the storage box 7 for storage.

[0023] Reference Figure 1-4 In this embodiment, the receiving mechanism 4 includes a guide frame 401, an auxiliary frame, and a guide hole 403. The guide frame 401 is fixed at an incline to the side of the protective plate 9. The auxiliary frame includes a frame 402 and a guide plate 4011. The frame 402 is fixed to both sides of the guide plate 4011. The guide hole 403 is located at the end of the guide frame 401, communicates with the protective plate 9, and is matched with the storage box 7. A first cylinder 404 is installed on the side of the guide frame 401. A connecting rod 407 is connected to the telescopic end of the first cylinder 404. Slide grooves 405 are opened on both sides of the guide frame 401. The connecting rod 407 is slidably disposed in the slide grooves 405. A hinge 409 is hinged to the end of the guide plate 4011. A base plate 408 is connected to the hinge 409. The connecting rod 407 is fixedly connected to the base plate 408. The end of the hinge 409 is provided with a shovel part 4010. The shovel part 4010 and the base plate 408 are slidably disposed inside the guide frame 401. A second cylinder 406 is movably disposed between the base plate 408 and the guide frame 401. Specifically, the connecting rod 407, the auxiliary frame, and the base plate 408 can be driven by the first cylinder 404 to slide on the guide frame 401, thereby adjusting the position of the auxiliary frame and the base plate 408. By driving the second cylinder 406, the tilt angle between the auxiliary frame and the base plate 408 can be adjusted, so as to better receive the gravel generated during repair according to the needs. The shovel part 4010 is provided so that when the auxiliary frame and the base plate 408 move on the guide frame 401, the adhering debris can be shoveled off.

[0024] According to the needs, the staff first adjusts the second cylinder 406 to change the tilt angle between the auxiliary frame and the base plate 408 to adapt to the tilt during repair. After the adjustment, according to the actual needs, the first cylinder 404 is activated, which drives the connecting rod 407, the auxiliary frame and the base plate 408 to slide on the guide frame 401. This allows the auxiliary frame to fit better under the roadway to be repaired, and can better receive the gravel generated during repair. The gravel generated during repair enters the storage box 7 through the auxiliary frame, the guide frame 401 and the guide hole 403 for collection and storage.

[0025] Reference Figure 1and 6 In this embodiment, the top of the storage box 7 is provided with an inlet 701, which is connected to the protective plate 9 via a flexible hose and communicates with the guide hole 403. The storage box 7 is internally driven by two crushing wheels 703, and a guide plate 702 is provided above the crushing wheels 703. The storage box 7 is inclined as a whole, and the end of the storage box 7 is provided with a discharge notch, at which a baffle 704 is hinged. Specifically, after the crushed stone passes through the inlet 701, it can be crushed by driving the crushing wheels 703. The guide plate 702 facilitates the effective guidance of the crushed stone into the crushing wheels 703 for crushing, which reduces the storage space between the crushed stones and makes it easier to store more crushed stone. The inclined arrangement of the storage box 7 facilitates the subsequent material unloading. The baffle 704 prevents the crushed stone from flowing out prematurely.

A second lifting plate 6017 is slidably disposed on the upper part of the second vertical plate 6019. The second threaded block 6015 passes through the second vertical plate 6019 and is fixedly connected to the second lifting plate 6017. A second drilling rig 6016 is fixedly connected to the second lifting plate 6017. A second drill rod 6018 is connected to the output end of the second drilling rig 6016. The second drill rod 6018 is connected to the second... Drill rod 6012 can be of different sizes. Specifically, the orientation of the mounting frame 605 can be adjusted by setting the first motor 603. The setting of the polished rod 602 is convenient to adapt to the rotation of the mounting frame 605, which facilitates maintenance work inside the roadway as needed. The first screw 607 can be rotated by starting the servo motor 604. The rotation of the first screw 607 drives the first gear 606 to rotate, which in turn drives the second gear 6013 and the second screw 6014. By controlling the servo motor 604, the first drill rod 6012 and the second drill rod 6018 can be used alternately to carry out maintenance work on the coal mine roadway as needed.

[0027] Principle: By controlling the robotic arm 5, the operator adjusts the tilt angle of the entire repair mechanism 6 to adapt to the corresponding roadway requirements. After adjustment, the operator controls the first motor 603 to rotate the mounting frame 605 according to the requirements. The operator selects the corresponding position of the mounting frame 605 to adapt to the different locations in the roadway. After adjustment, the operator selects the corresponding drill rod according to the actual repair requirements. By controlling the servo motor 604, the operator drives the first screw 607 and transmits the second screw 6014. Thus, the operator can alternate between the first drill rod 6012 and the second drill rod 6018 according to the requirements, making it convenient to select the corresponding drill rod for repair work according to the needs.

Multiple fourth cylinders 807 are provided and are simultaneously installed between the connecting base plate 804 and the first vertical plate 805. Specifically, when the entire repair device moves, the ground shovel 3 shovels up the debris on the ground surface. After shoveling, the ground shovel 3 is driven forward by controlling the fourth cylinder 807. After being pushed forward, the third cylinder 803 is controlled so that the ground shovel 3 can rotate around the intersection of the adjusting rod 801 and the connecting rod 802, so that the shoveled debris can fall into the frame 402 and the guide plate 4011 for storage.

Control the second cylinder 406 and the first cylinder 404 to make the frame 402 and the guide plate 4011 fit as closely as possible to the guide frame 401. Control the third cylinder 803 to make the adjusting rod 801 flip, which drives the ground shovel 3 to flip, so that the debris shoveled in the ground shovel 3 can be transferred to the frame 402 and the guide plate 4011, and then imported into the storage box 7 for crushing and storage. S6. After the discharge, collection and repair work is completed, control the entire repair machine to move to the designated position, open the baffle 704, and discharge the collected gravel and debris.

[0033] Working Principle: The operator enters the control room 2 and controls various components through it. First, the moving track 1 is driven to move to the vicinity of the roadway to be repaired. The robotic arm 5 is controlled so that the repair mechanism 6 can better contact the roadway. After contact, the second cylinder 406 is controlled to adjust the tilt of the frame 402 and guide plate 4011. After adjustment, the first cylinder 404 is controlled to adjust the position of the frame 402 and guide plate 4011 to better adapt to material receiving requirements.
