Description

Technical Field

[0001] This invention relates to the field of underground fully mechanized mining support technology, specifically to a fully mechanized mining support with anti-slip function. Background Technology

[0002] Currently, fully mechanized longwall mining is widely used in underground coal mining. Due to the limitations of coal seam occurrence conditions, most fully mechanized longwall faces need to be arranged at a certain dip angle, with some reaching over 30°. When the roof and floor of the coal seam are relatively hard, the fully mechanized supports may slip during production. To prevent the fully mechanized supports from sliding downhill, i.e., sliding into the downwind roadway, anti-slip measures need to be taken for the fully mechanized supports.

[0003] Common methods include installing anti-slip tensioning devices in the upwind roadway of the working face and connecting the various fully mechanized mining supports with steel wire ropes; or arranging the working face in a pseudo-inclined (small-scale upward inclination) manner so that the movement of the fully mechanized mining supports tends to be upward as the working face advances. Some combine these two anti-slip methods, but regardless of the method used, it is difficult to guarantee that the fully mechanized mining supports will not slip, resulting in the problem of slipped fully mechanized mining supports remaining in the downwind roadway of most steeply inclined fully mechanized mining faces. After a long-strike working face is completed, approximately 10 fully mechanized mining supports are left in the downwind roadway. Due to the limitations of the downwind roadway's cross-section, these leftover supports are difficult to transport out and must be abandoned in the downwind roadway, leading to high mining costs.

[0034] (III) Beneficial Effects

[0035] The beneficial effects of this invention are:

[0036] The bottom surface of the base and the top surface of the top beam serve as the support surfaces for the main body of the fully mechanized mining support. The first anti-slip mechanism and the collecting hopper are installed in conjunction, and can be correspondingly installed on the base and / or the top beam. After the main body of the fully mechanized mining support completes coal seam support, the first anti-slip mechanism is activated. The first anti-slip pin extends through the first through-hole on the top beam and drills into the top surface of the coal seam, thereby enhancing the anti-slip performance of the fully mechanized mining support and preventing it from sliding down the windward roadway during production. The collecting hopper's collection opening encompasses multiple first through-holes on the top beam. Coal dust generated during the drilling of the first anti-slip pin can naturally fall into the collecting hopper through the first through-holes, effectively preventing coal dust generated during the drilling of the first anti-slip pin from splashing onto the equipment or getting stuck on the support surface of the coal seam floor, thus affecting the stability of the main body support of the fully mechanized mining support. The first anti-slip mechanism and collecting hopper installed on the base work similarly.

[0037] By anchoring the first anti-slip pin into the coal seam roof and / or coal seam floor, the support strength of the top beam and / or base is further improved, thereby preventing the fully mechanized mining support from sliding down the windward roadway during production. This also prevents the fully mechanized mining support from getting stuck in the downwind roadway wall. After the support structure of the fully mechanized mining support is reset, it can move with the advancement of the working face to continue the support operation without abandoning the fully mechanized mining support, thus saving production costs.

[0051] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0053] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; "connection" can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0055] See Figure 1 The present invention provides a fully mechanized mining support with anti-slip function. The fully mechanized mining support includes a fully mechanized mining support body 1 and a collection mechanism 2 and a first anti-slip mechanism 4 disposed inside the fully mechanized mining support body 1. At least one first through hole 107 is correspondingly opened on the support surface of the fully mechanized mining support body 1. The collection range of the collection bucket 204 of the collection mechanism 2 covers the material passage area of ​​one or more first through holes 107. The first anti-slip mechanism 4 is disposed between the collection bucket 204 and the support surface. The first anti-slip mechanism 4 is provided with a first anti-slip pin 401 that can pass through the first through hole 107 in a first direction.

[0056] In this embodiment, the main body 1 of the fully mechanized mining support includes a base 101, a top beam 102, a supporting hydraulic cylinder 103, a side guard plate 104, a shield beam 105, and a tail beam 106. The top beam 102 is arranged parallel to the base 101 via the supporting hydraulic cylinder 103. A side guard plate 104 is provided on one side of the top beam 102, and a shield beam 105 is provided on the other side. A tail beam 106 is provided on the side of the shield beam 105 away from the top beam 102. Adjustable hydraulic cylinders are hinged to the lower ends of both the tail beam 106 and the side guard plate 104, and the other ends of the adjustable hydraulic cylinders are correspondingly hinged to the diagonal brace or the top beam 102. Ultimately, support is provided by the base 101, top beam 102, side guard plate 104, shield beam 105, and tail beam 106. In this embodiment, the first direction is vertical, which is also the extension and retraction direction of the supporting hydraulic cylinder 103; the second direction is the radial direction of the first anti-slip pin 401.

[0057] The bottom surface of the base 101 and the top surface of the top beam 102 are both support surfaces of the main body 1 of the fully mechanized mining support. The first anti-slip mechanism 4 and the collection bucket 204 of the present invention are matched and can be correspondingly matched on the base 101 and / or the top beam 102. In this embodiment, the first anti-slip mechanism 4 and the collection bucket 204 are provided on the inner side of the base 101 and the inner side of the top beam 102. Taking the first anti-slip mechanism 4 and the collection bucket 204 provided on the top beam 102 as an example, after the main body 1 of the fully mechanized mining support completes the coal seam support, the first anti-slip mechanism 4 is activated, and the first anti-slip pin 401 extends out through the first through hole 107 opened on the top beam 102 and drills into the top surface of the coal seam, thereby enhancing the anti-slip performance of the fully mechanized mining support and preventing the fully mechanized mining support from sliding downwind roadway during production. The collection opening of the collecting hopper 204 encompasses multiple first through holes 107 on the top beam 102. Coal dust generated during the drilling of the first anti-slip pin 401 can naturally fall into the collecting hopper 204 through the first through holes 107, effectively preventing coal dust generated during the drilling of the first anti-slip pin 401 from splashing onto the equipment or getting stuck on the support surface of the coal seam floor, thus affecting the stability of the main body 1 of the fully mechanized mining support. The first anti-slip mechanism 4 installed on the base 101 works similarly to the collecting hopper 204, and will not be described further.

[0058] By drilling (which can be considered as anchoring) the first anti-slip pin 401 into the coal seam roof and / or coal seam floor, the support strength of the top beam 102 and / or base 101 is further improved, thereby preventing the fully mechanized mining support from sliding down the windward roadway during production, and thus preventing the fully mechanized mining support from getting stuck in the windward roadway wall. After the support structure of the fully mechanized mining support is reset, it can move with the advancement of the working face to continue the support operation without abandoning the fully mechanized mining support, thus saving production costs.

[0059] like Figure 2 As shown, the first anti-slip mechanism 4 further includes a first rotary driver 402, a support frame 403, and a first telescopic driver 404. The first telescopic driver 404 is mounted on the main body 1 of the fully mechanized mining support and connected to the support frame 403, so as to drive the support frame 403 to move along the first direction. The first rotary driver 402 is mounted on the support frame 403. The first rotary driver 402 is connected to the first anti-slip pin 401, so as to drive the first anti-slip pin 401 to rotate. In this embodiment, a U-shaped plate is connected to the top surface of the base 101 and / or the bottom surface of the top beam 102. One end of the first telescopic driver 404 is mounted on the U-shaped plate, and the other end is connected to the crossbeam of the support frame 403. By driving the first telescopic driver 404 to work, the crossbeam can be raised and lowered in the groove of the U-shaped plate along the first direction, thereby driving the first anti-slip pin 401 to rise and fall in the first direction through the support frame 403. The first rotary driver 402 can synchronously drive the first anti-slip pin 401 to rotate during the process of the first anti-slip pin 401 moving up and down in the first direction, thereby improving the anchoring efficiency of the first anti-slip pin 401 by rotation.

[0060] It should be noted that the first anti-slip pin 401 of this invention is driven to rotate by the first rotary driver 402 to improve anchoring efficiency, not to drill. In this embodiment, by driving the first anti-slip pin 401 to rotate relatively slowly, the drilling efficiency of the first anti-slip pin 401 is improved on the one hand, and the first anti-slip pin 401 is allowed to fully contact the coal seam, applying prestress and improving the support strength of the fully mechanized mining support, resulting in stronger vibration resistance. Of course, the first anti-slip pin 401 can also be drilled directly, with the hole wall limiting the first anti-slip pin 401, but the limiting strength is lower than that of the anchoring method, especially when multiple first anti-slip pins 401 are being used in construction, the difference is more obvious.

[0061] Furthermore, a plurality of first rotary actuators 402 are evenly arranged along the circumference of the support frame 403; the plurality of first rotary actuators 402 are connected one-to-one with a plurality of first anti-slip pins 401. In this embodiment, three first rotary actuators 402 are evenly arranged on a support frame 403, and the three first rotary actuators 402 drive the three first anti-slip pins 401 to rotate, so that the three first anti-slip pins 401 can anchor into the coal seam in an isosceles triangle, further enhancing the anti-slip performance of the fully mechanized mining support.

[0062] Secondly, the first anti-slip mechanism 4 also includes guide rods 405 installed on the main body 1 of the fully mechanized mining support and / or the collection hopper 204; guide holes are provided on the support frame 403; the guide rods 405 and the guide holes are slidably connected along the first direction. In this embodiment, multiple guide rods 405 are evenly arranged along the circumference of the support frame 403. The guide rods 405 are welded to the bottom end of the top beam 102 or to the inner wall of the collection hopper 204, so that the support frame 403 can rise and fall along the first direction with multiple guide rods 405. The guide rods 405 play a guiding role and enhance the structural strength of the first anti-slip mechanism 4, effectively improving the stability of the lifting and anchoring of the support frame 403. The first anti-slip mechanism 4 on the base 101 is set accordingly with reference to the first anti-slip mechanism 4 on the top beam 102.

[0063] See Figure 3In one embodiment, the first anti-slip pin 401 has a built-in second anti-slip mechanism 5, that is, the second anti-slip mechanism 5 is disposed in the opening inside the first anti-slip pin 401; the second anti-slip mechanism 5 includes a second telescopic actuator 501, a mounting plate 507, a second rotary actuator 505, and a second anti-slip pin 506; the mounting plate 507 is slidably disposed on the first anti-slip pin 401 along the second direction, and the second rotary actuator 505 is mounted on the mounting plate 507; the second rotary actuator 505 is connected to the second anti-slip pin 506 so as to drive the second anti-slip pin 506 to rotate; a second through hole 407 is provided on the wall surface of the first anti-slip pin 401, and the second anti-slip pin 506 can pass through the second through hole 407 along the second direction; the second telescopic actuator 501 is connected to the mounting plate 507 so as to drive the mounting plate 507 to move along the second direction. Specifically, the second direction is the sliding direction of the mounting plate 507 inside the first anti-slip pin 401. It can be the radial direction of the first anti-slip pin 401; or it can be offset at a certain angle in the radial direction to anchor into the coal seam roof or floor in an inclined upward or inclined downward posture. After the first anti-slip mechanism 4 is anchored into the coal seam, the second telescopic actuator 501 drives the mounting plate 507 to move along the second direction. The mounting plate 507 simultaneously drives the second rotary actuator 505 and the second anti-slip pin 506 to move along the second direction. The second rotary actuator 505 drives the second anti-slip pin 506 to rotate to enhance the smoothness of the second anti-slip pin 506 anchoring into the coal seam. The first anti-slip pin 401 and the second anti-slip pin 506 are anchored into the coal seam from different directions, working together to greatly enhance the support stability of the fully mechanized mining support and avoid slippage relative to the coal seam roof and floor during production.

[0064] In another embodiment, the second anti-slip mechanism 5 further includes a pusher 502, an inclined push plate 503, and a return spring 504; the first anti-slip pin 401 has a built-in support rod 406, and the mounting plate 507 is slidably disposed on the support rod 406 in the second direction; the support rod 406 is fitted with a return spring 504, one end of the return spring 504 is connected to the inner wall of the first anti-slip pin 401, and the other end is connected to the mounting plate 507; the second telescopic driver 501 is connected to the pusher 502, the pusher 502 is provided with a column 508, and the mounting plate 507 is provided with an inclined push plate 503; when the second telescopic driver 501 drives the pusher 502 to move in the first direction, the column 508 can push the inclined push plate 503 to move in the second direction. Specifically, the column 508 is vertically mounted on the pusher 502. Since the contact surface between the inclined push plate 503 and the column 508 is an inclined plane, the inclined push plate 503 can be pushed synchronously as the column 508 rises in the first direction. This causes the inclined push plate 503 to drive the mounting plate 507 to slide in the second direction, thereby enabling the second rotary drive 505 and the second anti-slip pin 506 to move in the second direction. Furthermore, when the fully mechanized mining support needs to be retrieved, during the reset process of the second telescopic drive 501, the reset spring 504 can push the mounting plate 507 to reset in the second direction, allowing the inclined push plate 503 to reset in a stable position against the top of the column 508, effectively improving the stability of the second anti-slip pin 506 reset process. In this way, the driving force of the second telescopic actuator 501 in the first direction is converted into the driving force of the second anti-slip pin 506 moving in the second direction, which is adapted to the opening of the first anti-slip pin 401 with a small radial installation space and a large vertical installation space, thereby improving the reliability of integrating the second anti-slip mechanism 5 inside the first anti-slip mechanism 4.

[0065] Optionally, the push frame 502 is provided with multiple columns 508 of different heights; the multiple columns 508 correspond one-to-one with multiple inclined push plates 503 in sliding contact; when the second telescopic driver 501 drives the push frame 502 to move in the first direction, the multiple second anti-slip pins 506 can move synchronously in the second direction. Specifically, by providing multiple columns 508 on the push frame 502, each column 508 cooperates with an inclined push plate 503, realizing the synchronous driving of multiple second anti-slip pins 506 in the second direction. This driving process is only driven by one second telescopic driver 501, thus saving equipment costs and subsequent maintenance and cleaning costs, and ensuring the drilling and resetting efficiency of multiple second anti-slip pins 506.

[0066] In this embodiment, the second direction is the radial direction of the first anti-slip pin 401. The radial direction of the first anti-slip pin 401 refers to any direction in the horizontal plane, so that when multiple second anti-slip pins 506 are arranged for anchoring, the multiple second anti-slip pins 506 can be anchored from different directions, further improving the support stability of the fully mechanized mining support.

[0067] See Figure 4 The fully mechanized mining support also includes a collection bucket 3 and a cleaning mechanism 6 partially built into the collection bucket 3; the cleaning mechanism 6 includes a third rotary drive 601, a transmission gear set 602, a rotating shaft 603, and a cleaning frame 604; the collection bucket 3 is connected to the collection hopper 204; the third rotary drive 601 is externally mounted on the collection bucket 3 and connected to the transmission gear set 602 built into the collection bucket 3; one end of the rotating shaft 603 is connected to the transmission gear set 602, and the other end is connected to the cleaning frame 604; the cleaning frame 604 is provided with at least one scraper 606 that slides against the inner wall of the collection bucket 3; the third rotary drive 601 can drive the scraper 606 to rotate around the axis of the collection bucket 3. In this embodiment, coal dust that falls naturally through the first through hole 107, is guided out of the ground by the first anti-slip pin 401, or splashes into the collection bucket 204 through the first anti-slip pin 401 is collected directionally by the collection bucket 3. This prevents the coal dust from accumulating on the support surface and the first anti-slip mechanism 4, which would affect the support stability of the fully mechanized mining support or the stability of the equipment operation. The bottom of the cleaning mechanism 6 is provided with a chip discharge port, which can be opened periodically according to the number of operations to clean the debris collected inside the collection bucket 3. During cleaning, the scraper 606 can be driven to rotate around the axis of the collection bucket 3 by the third rotary drive 601, so that the scraper 606 scrapes off the coal dust adhering to the inner wall of the collection bucket 3, thereby improving the cleaning quality and efficiency of the collection bucket 3.

[0068] Specifically, a horizontal plate 605 is provided at the top of the inner side of the collection bucket 3. The bottom end of the horizontal plate 605 is rotatably connected to a rotating shaft 603 via a bearing. The rotating shaft 603 is connected to the upper cross-shaped bracket. The four free ends of the upper cross-shaped bracket are connected to the top of the inner side of the four scrapers 606, and the bottom of the inner side of the four scrapers 606 are connected to the lower cross-shaped bracket. The upper and lower cross-shaped brackets are arranged in parallel. An installation plate is provided on the outer wall of the collection bucket 3. The third rotary drive 601 is installed on the installation plate. The shaft of the third rotary drive 601 extends into the wall of the collection bucket 3 and is connected to the transmission gear set 602. The transmission gear set 602 can be a bevel gear set 602, so that the third rotary drive 601 can drive the cleaning frame 604 to rotate around the shaft of the rotating shaft 603, and finally realize the scraping operation of the scraper 606.

[0069] The first rotary driver 402, the second rotary driver 505 and the third rotary driver 601 of the present invention can be selected as motors or electric motors, and the first telescopic driver 404 and the second telescopic driver 501 can be selected as electric push rods, cylinders or hydraulic cylinders.

[0070] like Figure 5 and Figure 6As shown, the fully mechanized mining support also includes a collection mechanism 2 mounted on the collection bucket 3; the collection mechanism 2 includes a chip suction pump 201, a conduit 202, and a chip suction pipe frame 203; the chip suction pipe frame 203 includes an annular pipe 205 and multiple V-shaped pipes 206 arranged circumferentially along the annular pipe 205; the annular pipe 205 is fitted onto the collection bucket 3; one end of the V-shaped pipe 206 is connected to the annular pipe 205, and the other end is connected to the collection hopper 204; the annular pipe 205 is connected to the first end of the conduit 202; one end of the chip suction pump 201 is connected to the second end of the conduit 202, and the other end is connected to the collection bucket 3. In this embodiment, a first anti-slip mechanism 4 is correspondingly provided on the base 101 and the top beam 102, and therefore a collection hopper 204 is also correspondingly provided to block and collect coal chips. When both the base 101 and the top beam 102 are equipped with a first anti-slip mechanism 4, it becomes difficult for the collecting hopper 204 on the base 101 to collect coal dust. Furthermore, during frequent operation, coal dust tends to accumulate on the top surface of the base 101, which negatively impacts the operation of the first anti-slip mechanism 4. Therefore, a pump is used to suck the coal dust from the collecting hopper 204 on the base 101 into the collecting bucket 3. This allows the collecting hopper 204 on the base 101 to operate synchronously with the collecting hopper 204 on the top beam 102 for extended periods, reducing cleaning frequency and improving production efficiency.

[0071] Specifically, the chip suction pipe frame 203 extends multiple V-shaped pipes 206 into the collection hopper 204 of the base 101. After the chip suction pump 201 is turned on, the coal chips in the collection hopper 204 of the base 101 can sequentially enter the collection bucket 3 through the V-shaped pipes 206, the guide pipe 202, and the chip suction pump 201. The chip suction pipe frame 203 can be sleeved on the collection bucket 3 or abutted against the connection between the collection bucket 3 and the collection hopper 204 of the base 101 through the annular pipe 205. This achieves both external placement of the chip suction pipe frame 203, avoiding affecting the operation of the first anti-slip mechanism 4 inside the collection hopper 204, and support of the chip suction pipe frame 203 by the collection bucket 3 and the base 101, so that when adsorbing coal chips, the weight of the coal chips can be applied to the collection bucket 3 or the collection hopper 204, improving the reliability of the pipeline adsorbing coal chips.

[0072] It should be noted that the first anti-slip pin 401 and the second anti-slip pin 506 of the present invention are used for anchoring rather than drilling, so the amount of coal dust generated is limited, and therefore the coal dust falling onto the first anti-slip mechanism 4 has a limited impact on the operation of the first anti-slip mechanism 4. Optionally, the collection hopper 204 has a built-in suction tube, one end of which is located near the first through hole 107, and the other end is connected to the V-shaped tube 206 or the collection bucket 3; the suction tube is inserted through the gap of the support frame 403 and can be tied to the support frame 403 with a cable tie. In this way, the coal dust entering through the first through hole 107 can be adsorbed by the suction tube, which greatly reduces the situation of coal dust adhering to the first anti-slip mechanism 4, reduces the cleaning frequency of the first anti-slip mechanism 4, and improves production efficiency.
