Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, specifically to a continuous wire saw mining device for thin veins. Background Technology

[0002] In the mining industry, the extraction of thin veins has always faced numerous technical challenges. Traditional methods for extracting thin veins mainly include manual rock drilling and blasting, and mechanical cutting, but these methods generally suffer from low efficiency, poor safety, and insufficient resource recovery rates. Specifically:

[0003] 1. Although manual rock drilling and blasting is suitable for complex geological conditions, it has problems such as high labor intensity, dangerous working environment, and blasting vibration that can easily loosen the surrounding rock layers of the ore vein. In addition, it is difficult to achieve continuous mining, which seriously affects mining efficiency.

[0004] 2. Mechanical cutting methods, using equipment such as chainsaws and circular saws, can reduce the safety hazards associated with blasting. However, these devices are bulky and difficult to adapt to the narrow working spaces of thin ore veins. Furthermore, their cutting depth is limited, hindering efficient continuous mining. In addition, traditional mechanical cutting equipment lacks flexibility and struggles to adjust its cutting posture according to the vein's orientation, resulting in lower ore recovery rates.

[0005] 3. In recent years, wire saw technology has been gradually introduced into the mining field due to its advantages such as wide cutting range, strong adaptability, and high operating precision. However, existing wire saw equipment is mostly designed for thick ore bodies, and has the following limitations in the mining of thin veins:

[0006] (1) Insufficient spatial adaptability: Thin ore veins are relatively thin, and traditional wire saw equipment is difficult to arrange stably in a limited space. It is also easy to interfere with the ore wall or the equipment itself, affecting the cutting effect.

[0007] (2) Weak continuous mining capability: Most wire saw equipment can only perform unidirectional cutting, and the equipment position needs to be adjusted frequently, which makes it impossible to achieve continuous downward mining of the vein, resulting in low operating efficiency.

[0008] (3) Difficulty in collecting ore: The crushed ore is scattered on the working face, and there is a lack of efficient collection and transportation system, which increases the subsequent cleaning and transportation costs.

[0009] Therefore, there is an urgent need to design a wire saw continuous mining device specifically for thin vein mining, which can adapt to narrow ore seam spaces and achieve efficient and stable segmented continuous mining and cutting operations to improve the economy and safety of thin vein mining.

[0035] The beneficial effects of this invention are:

[0036] 1. High-efficiency continuous mining improves production efficiency. Multiple sets of wire saws are arranged in parallel, which can simultaneously carry out multi-face mining on thin ore vein working surfaces, greatly improving mining efficiency. Through synchronous release and retraction control, the reciprocating cutting motion of the wire saw is realized, avoiding the frequent reset of traditional unidirectional cutting, realizing continuous downward mining of the ore vein. The traveling unit is automatically advanced, which, together with the wire saw cutting, forms a continuous operation cycle of cutting-crushing-advancement, reducing manual intervention and improving the degree of automation in mining.

[0037] 2. Adapting to narrow ore vein spaces and improving resource recovery rates, the attitude adjustment component can adjust the tilt angle, extension, and spacing of the wire saw to precisely adapt to the direction and thickness changes of thin ore veins, avoiding interference with the ore wall or the equipment itself. The tracked traveling unit can move stably on both sides of the ore vein, adapting to complex terrain and ensuring flexible movement and precise positioning of the equipment in narrow spaces. The spacing adjustment mechanism can dynamically adjust the spacing between adjacent wire saws, optimizing the cutting layout, reducing ore waste, and improving the mining recovery rate of thin ore veins.

[0038] 3. Stable cutting and reduced equipment wear: The dual wire rope synchronous traction design enhances the stability of the wire saw operation, reduces sway and vibration, and extends service life. The tensioning mechanism adjusts the wire rope tension in real time to ensure that the wire saw is always taut, improving cutting efficiency and preventing the risk of rope breakage. Meanwhile, the support components provide stable support during operation, preventing the equipment from shifting due to cutting reaction force, ensuring cutting accuracy and equipment safety.

[0039] 4. Automated ore collection and transfer reduces labor costs. The ore collection and transfer components can automatically collect crushed ore and transport it to designated locations, reducing manual cleaning and handling costs.

[0040] 5. Easy to maintain and expand: The drive component adopts spline shaft transmission, which enables the take-up and take-down components to maintain power transmission even when the spacing is adjusted, thus improving system reliability. The worm gear self-locking mechanism ensures stable fixation after the spacing is adjusted, preventing deviation during operation. The modular design of the take-up and take-down components facilitates quick replacement or expansion, adapting to the mining needs of different veins. Attached Figure Description

Detailed Implementation

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0052] Please see Figure 1 , Figure 2 A continuous wire saw mining apparatus for thin vein ore, comprising:

[0053] The traveling unit 1 comprises two sets, which are respectively arranged on the upper and lower sides of the thin vein;

[0054] The retraction and extension assembly 2 and the wire saw 3 are arranged on the traveling unit 1. The wire saw 3 passes through the thin ore vein and its two ends are respectively connected to the retraction and extension assembly 2 set on the two traveling units 1. The retraction and extension assembly 2 realizes the reciprocating motion of the wire saw 3 by controlling the retraction and extension of the wire saw 3. The reciprocating wire saw 3 cuts the thin ore vein.

[0055] The attitude adjustment component 4 is mounted on the traveling unit 1 and is used to assemble the retraction component 2. The attitude adjustment component 4 can adjust the tilt angle, extension attitude, and spacing of the retraction component 2.

[0056] The traveling unit 1 can ensure that the other components are stably assembled and operated on it. The two traveling units 1 are respectively arranged on the upper and lower sides of the thin ore vein in the mine and maintain the same direction and speed. The mining operation of the thin ore vein in the mine is realized by means of the wire saw 3 connected between the two traveling units 1.

[0057] The attitude adjustment component 4 can ensure that multiple sets of retractable components 2 are stably assembled on it and achieve horizontal spacing adjustment. The retractable components 2 arranged in the same vertical direction in the two sets of traveling units 1 are connected with the corresponding wire saws 3, and multiple sets of wire saws 3 can be arranged within the working width range to achieve efficient mining of thin ore veins.

[0058] Furthermore, the attitude adjustment component 4 can also adjust the tilt angle and extension attitude of the retraction component 2 to avoid spatial interference with other components of the device when passing through thin ore vein working areas, so as to ensure the safety and stability of mining operations.

[0059] Each set of take-up and release components 2 on the same travel unit 1 operates synchronously, while the take-up and release components 2 on different travel units 1 operate in opposite directions. That is, when one set of take-up and release components 2 on one travel unit 1 pulls back the corresponding wire saw 3 synchronously, the take-up and release components 2 on the other travel unit 1 release the corresponding wire saw 3 synchronously. This process is repeated, which can drive the reciprocating motion of the wire saw 3, thereby achieving the cutting and crushing of thin ore veins.

[0060] When mining thin ore veins, two sets of traveling units 1 travel on the upper and lower working faces of the thin ore vein respectively, and drill multiple vertically distributed holes in the thin ore vein so that the wire saw 3 can pass through each hole and be fixedly connected to the wire ropes at both ends. While the traveling units 1 travel at a set speed, the wire saw 3 is driven to reciprocate by the take-up and take-down components 2 on both sides of the thin ore vein. The wire saw 3 can cut the ore forward at the drill hole position to realize the mining of ore.

[0061] The mining equipment provided in this solution adopts segmented continuous mining to adapt to the distribution pattern of thin ore veins. Specifically, when mining in the area where a thin ore vein is located, the spacing between the sets of take-up and release components 2 can be actively adjusted according to the width of the thin ore vein to meet the distribution requirements of the thin ore vein and complete the mining operation of a section of thin ore vein. Afterwards, the wire saw 3 is disconnected from the wire ropes 25 at both ends and moved to the next thin ore vein mining area. The above operation is repeated. According to the distribution area of ​​the thin ore vein, drilling, adjustment of the spacing of the take-up and release components 2, and adjustment of the attitude adjustment component 4 are performed to make the wire saw 3 evenly distributed in the width direction of the thin ore vein. Under the overall coordination of the traveling unit 1 and the take-up and release components 2, the ore mining work of the next mining area is completed. Example

[0062] Please see Figures 1-3 To ensure that the traveling unit 1 can drive the components loaded on it to travel and operate stably in the environment above and below the thin ore vein layer, the following technical solution is provided.

[0063] The traveling unit 1 includes a carrying platform 11, traveling tracks 12, and support components 13. The traveling tracks 12 are mounted on both sides of the carrying platform 11, and the support components 13 are mounted on the front and rear ends of the carrying platform 11.

[0064] The support assembly 13 includes a connecting bracket 131, a telescopic cylinder A132, a telescopic cylinder B133, and a support pad 134. The connecting bracket 131 is fixedly installed at both ends of the bearing platform 11. The fixed end of the telescopic cylinder A132 is rotatably connected to the connecting bracket 131. The movable end of the telescopic cylinder A132 is hinged to the support pad 134. The two ends of the telescopic cylinder B133 are respectively hinged to the telescopic cylinder A132 and the bearing platform 11.

[0065] The support platform 11 can ensure that the take-up and take-down components 2 are stably assembled on it, and ensure that the support components 13 can be stably installed and provide stable support for the support platform 11, so as to provide a stable working platform for the normal operation of the equipment.

[0066] The track 12 is mounted on both sides of the carrying platform 11 to drive the carrying platform 11 to move stably along the direction of the thin vein. At the same time, the track structure can ensure stable movement in the vein layer environment and improve obstacle crossing ability. The support component 13 can provide stable support during the mining operation.

[0067] During the movement of the track 12, the support assembly 13 is in a retracted state. At this time, both telescopic cylinders A132 and B133 are in a retracted posture, thus ensuring that the support pad 134 is away from the ground and avoiding interference with the normal movement of the traveling unit 1. During the operation phase, telescopic cylinders A132 and B133 are in an extended state, providing oblique support for the carrying platform 11, thereby ensuring stable contact between the support pad 134 and the ground.

[0068] To ensure that the attitude adjustment component 4 can be stably installed on the traveling unit 1 and to achieve stable adjustment of tilt and retraction attitudes, the following technical solution is provided.

[0069] The attitude adjustment component 4 includes an assembly frame 41, a telescopic cylinder C42, a telescopic arm 43, and a telescopic cylinder D44. The bottom end of the assembly frame 41 is hinged to the support platform 11. The two ends of the telescopic cylinder C42 are respectively hinged to the assembly frame 41 and the support platform 11. A guide rail A411 is fixedly connected in the assembly frame 41. The telescopic arm 43 is arranged in the assembly frame 41. A support wheel A431 is rotatably installed on the outer wall of the telescopic arm 43. The support wheel A431 and the guide rail A411 are matched and combined. The two ends of the telescopic cylinder D44 are respectively fixedly connected to the assembly frame 41 and the telescopic arm 43.

[0070] When the telescopic cylinder C42 is extended, it can drive the assembly frame 41 and the telescopic arm 43 assembled therein to rotate along the hinge point, thereby achieving stable adjustment of the tilt angle. The cooperation between the guide rail A411 and the support wheel A431 enables the telescopic arm 43 to extend and retract stably in the assembly frame 41. By controlling the extension and retraction posture of the telescopic cylinder D44, the extension and retraction movement of the telescopic arm 43 in the assembly frame 41 is controlled.

[0071] The cooperation of telescopic cylinders C42 and D44 enables precise adjustment of the posture of the extension and retraction assembly 2, ensuring that the connected wire saw 3 is stably arranged on the working face of the thin ore vein and ensuring the stable operation of the wire saw 3 to avoid spatial movement interference with the various components involved in the device. Example

[0072] Please see Figures 3-5 , Figure 7 , Figure 9 To ensure that the retraction and extension assembly 2 can control the retraction and extension of the wire saw 3 to achieve the reciprocating motion of the wire saw 3 and thus achieve efficient cutting of thin ore veins, the following technical solution is provided.

[0073] The take-up and take-down assembly 2 includes multiple sets arranged side by side, and each set of take-up and take-down assembly 2 is connected to a wire saw 3.

[0074] The take-up and release assembly 2 includes an assembly bracket 21, a rope winding roller 22, a tensioning mechanism 23, a guide wheel assembly 24, and a wire rope 25. The assembly bracket 21 is assembled onto the attitude adjustment assembly 4. The rope winding roller 22 and the guide wheel assembly 24 are rotatably installed in the assembly bracket 21. The wire rope 25 is wound around the rope winding roller 22, and one end of the wire rope 25 is arranged around the guide wheel assembly 24. The end of the wire rope 25 is fixedly connected to the wire saw 3. The tensioning mechanism 23 is installed on the assembly bracket 21 and is used to adjust the tension of the wire rope 25.

[0075] On each traveling unit 1, by setting up multiple sets of take-up and take-down components 2 and corresponding connected wire saws 3, mining operations can be carried out on multiple working faces of thin ore veins, which greatly improves the mining efficiency of thin ore veins.

[0076] The mounting bracket 21 enables stable installation on the attitude adjustment component 4 and ensures stable assembly of components such as the rope winding roller 22, tensioning mechanism 23, guide wheel group 24, and wire rope 25 on it.

[0077] By driving the rope roller 22 to rotate forward or backward, the wire rope 25 can be adjusted in its winding and unwinding posture, thereby achieving synchronous adjustment of the winding and unwinding posture of the connected wire saw 3. The guide wheel group 24 ensures that the wire rope 25 is stably erected and can be reciprocated for winding and unwinding adjustment, while the tensioning mechanism 23 can keep the wire rope 25 in a taut state and ensure that the wire saw 3 is also in a taut state, thus achieving effective cutting of thin ore veins.

[0078] Steel wire ropes 25 are extended from the two sets of traveling units 1 and located on the upper and lower sides of the thin ore vein. Under the guidance of the corresponding guide wheel set 24, the steel wire rope 25 on the upper side of the thin ore vein extends vertically downward, while the steel wire rope 25 on the upper side of the thin ore vein extends vertically upward. The ends of the two sets of steel wire ropes 25 are fixedly connected to the two ends of the wire saw 3, thereby driving the wire saw 3 to reciprocate and achieve effective cutting of the thin ore vein.

[0079] Based on the above design, the winding directions of the upper and lower sets of wire ropes 25 and the corresponding guide wheel sets 24 are slightly different. That is, the wire rope 25 on the upper side of the thin vein passes down from above the end guide wheel, while the wire rope 25 on the lower side of the thin vein passes up from below the end guide wheel.

[0080] To ensure that the retraction and deployment components 2 of each group can be stably assembled on the attitude adjustment components 4 set on the corresponding travel unit 1, and to achieve precise adjustment of the spacing between the retraction and deployment components 2 through the attitude adjustment components 4, the following technical solution is provided.

[0081] The attitude adjustment component 4 also includes a mounting frame 45, which is fixed to the end of the telescopic arm 43 and is perpendicular to the telescopic arm 43. A guide rail B451 is fixed in the mounting frame 45, and a support wheel B211 that is matched with the guide rail B451 is rotatably mounted on the mounting bracket 21.

[0082] The attitude adjustment component 4 also includes a spacing adjustment mechanism, which includes a guide post 461, a threaded rod 462, a drive motor A463, and a drive shaft 464. The guide post 461 and the threaded rod 462 are fixedly installed in the mounting frame 45. The mounting bracket 21 is slidably connected to the guide post 461. There are two sets of threaded rods 462, which are respectively arranged on both sides of the mounting bracket 21. The drive motor A463 is fixedly installed on the mounting bracket 21. The drive shaft 464 is poweredly connected to the drive motor A463 and has a drive bevel gear A465 fixedly connected to its end. Each threaded rod 462 is screwed with a transmission bevel gear A466. The transmission bevel gear A466 is rotatably installed on the mounting bracket 21 and meshes with the drive bevel gear A465.

[0083] The guide column 461, along with the matching guide rail B451 and support wheel B211, ensures that the assembly bracket 21 runs stably along the straight line of the mounting frame 45, thereby adjusting the spacing between the two adjacent sets of take-up and take-down components 2. A worm gear 467 is fixedly connected to the output shaft of the drive motor A463, while a worm wheel 468, which is matched with the worm gear 467, is coaxially fixed to the drive shaft 464. The combination of the worm gear 467 and the worm wheel 468 can reduce the speed and increase the torque of the power, thereby driving the drive bevel gear A465 and the transmission bevel gear A466 to run stably. The combination of the worm wheel 468 and the worm gear 467 also has a one-way self-locking characteristic, which can lock the drive bevel gear A465 and the transmission bevel gear A466 when the drive motor A463 is stopped, thereby preventing the take-up and take-down components 2 from undergoing invalid displacement.

[0084] When the drive motor A463 drives the transmission bevel gears A466 on both sides to rotate, it can cooperate with the threaded rod 462, thereby driving the assembly bracket 21 and the various components assembled on it to slide stably along the guide post 461.

[0085] A spacing sensor is also mounted on the mounting bracket 21 to monitor the spacing between adjacent take-up and take-up components 2, and then work with the spacing adjustment mechanism to effectively adjust the spacing between adjacent take-up and take-up components 2. Example

[0086] Please see Figures 4-9 To ensure that the rope winding rollers 22 of each take-up and release component 2 in the same travel unit 1 can operate synchronously and realize the synchronous take-up and release of the rope saw 3, the following technical solution is provided.

[0087] It also includes a drive assembly 5, which includes a drive motor B51 and a splined shaft 52. The splined shaft 52 is rotatably mounted in the mounting frame 45 and maintains a power connection with the drive motor B51.

[0088] The mounting bracket 21 is rotatably mounted with a drive bevel gear B212 and a transmission bevel gear B221 that are engaged. The spline shaft 52 is slidably inserted into the axis of the drive bevel gear B212, and the transmission bevel gear B221 is poweredly connected to the rope winding roller 22.

[0089] To ensure that the center of gravity of the mounting frame 45 and all components mounted on it falls as far as possible on the telescopic arm 43, the drive motor B51 is fixedly mounted to the center of the mounting frame 45. A transmission shaft 53 is fixedly connected to the output shaft of the drive motor B51. The transmission shaft 53 is rotatably mounted on the mounting frame 45. Transmission sprockets B54 are fixedly connected to both ends of the transmission shaft 53 and the spline shaft 52. The transmission sprockets B54 are connected to each other through a chain to achieve power connection between the drive motor B51 and the spline shaft 52, thereby avoiding spatial motion interference between the drive motor and the operating retraction and extension assembly 2.

[0090] The drive motor B51 is a geared motor. Since the spline shaft 52 always maintains a sliding connection with the drive bevel gear B212 installed on each set of assembly brackets 21, it can receive the power of the spline shaft 52 at any position of the assembly bracket 21, and then drive the rope winding roller 22 to operate stably through the transmission bevel gear B221.

[0091] To ensure that the retraction and extension components 2 set on the same vertical direction on the two sets of traveling units 1 can be stably connected to the wire saw 3, the following technical solution is provided.

[0092] The mounting bracket 21 is equipped with a tensioning mechanism 23, a guide wheel group 24, and two sets of rope winding rollers 22. Both sets of rope winding rollers 22 have a transmission sprocket A222 fixedly connected to the same end. The two sets of transmission sprockets A222 are connected by a chain. A transmission bevel gear B221 is fixedly connected to the shaft of one set of rope winding rollers 22.

[0093] Two sets of rope winding rollers 22 operate synchronously through a transmission sprocket A222 to simultaneously wind and unwind the wire ropes 25 wound on them. The two sets of wire ropes 25 are then led out through the control of the guide wheel group 24 and the tensioning mechanism 23. The two sets of wire ropes 25 are fixedly connected to the wire saw 3 through the connector 251. The two sets of synchronously operating wire ropes 25 work together to pull the wire saw 3, which can ensure the stability of the wire saw 3.

[0094] To ensure that the tensioning mechanism 23 can apply a stable tension force to the wire rope 25, thereby ensuring that the wire rope 25 and the connected wire saw 3 are always in a taut state to achieve effective cutting of thin ore veins, the following technical solution is provided.

[0095] The tensioning mechanism 23 includes a telescopic cylinder E231 and a pressure wheel 232. The telescopic cylinder E231 is fixedly installed on the mounting bracket 21, and the pressure wheel 232 is rotatably installed on the movable end of the telescopic cylinder E231. The wire rope 25 is arranged around the pressure wheel 232.

[0096] A stress sensor can be installed on the wire rope 25 to detect the tension of the wire rope 25. When the tension is less than the set threshold, the telescopic cylinder E231 is controlled to extend to drive the pressure wheel 232 to run synchronously, thereby pressing the wire rope 25 to an appropriate tension level, thus ensuring that the wire saw 3 can always effectively cut and crush thin ore veins. Example

[0097] Please see Figure 1 , Figure 2 To ensure that the ore cut and crushed by the wire saw 3 can be effectively collected and transported to a specific location outside the mine, the following technical solution is provided.

[0098] It also includes a ore collection and transfer component 6, which includes a conveyor belt 61 and a guide baffle 62. The conveyor belt 61 is mounted on the carrying platform 11 of the traveling unit 1 located below the thin ore vein, and the guide baffle 62 is fixedly installed on the upstream section of the conveyor belt 61 and arranged directly below the thin ore vein mining face.

[0099] The guide baffle 62 is positioned directly below the thin vein mining face, while the conveyor belt 61 can be stably installed on the traveling unit 1 below. After the wire saw 3 cuts and crushes the thin vein, the crushed ore falls onto the guide baffle 62 and, under the guiding and conveying action of the guide baffle 62, falls into the upstream end of the conveyor belt 61, which then transports it to a designated location outside the mine. This effectively transfers the mined ore to facilitate subsequent thin vein mining.

[0100] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0101] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
