[0036] like Figures 1 to 4As shown, the present application provides an underground mining and transportation device, which includes a support platform 10, a lifting assembly 20, a barrel 30 and a transport member 40. The support platform 10 is used to be fixed on the inner wall of the shaft 1. The lifting assembly 20 has a lifting sheave 21, a first driving member 22 and a first connecting rope 23.

[0037] By applying the technical solution of the present application, the support platform 10 is arranged on the inner wall of the shaft 1, the lifting sheave 21 is arranged on the support platform 10, one end of the first connecting rope 23 is connected to the first driving member 22, and the other end of the first connecting rope 23 bypasses the lifting sheave 21 and is connected to the barrel 30, the barrel 30 is used to hold coal gangue or construction materials for masonry of the inner wall of the shaft 1, the staff can use the construction materials to process the inner wall of the shaft 1, and the transport member 40 can transport the coal gangue to the outside of the shaft. With the above structure, the support platform 10 has a simple structure, and the support platform 10 can be quickly built, saving various materials required for the processing of the derrick, reducing the processing and manufacturing costs, and saving the time of the derrick installation, greatly shortening the construction period, and also greatly reducing the installation risk and the difficulty of deepening the shaft 1, and improving the work efficiency during the deepening of the shaft 1. Moreover, such an arrangement can ensure the rationality of the arrangement of the support platform 10 and the lifting assembly 20, make better use of the limited space underground, arrange the lifting assembly 20 reasonably and quickly, reduce costs, reduce labor intensity, and improve work efficiency.

[0038] In the present application, the barrel 30 is a container for lifting coal slag, gangue, construction materials, and workers in the deepening of the shaft 1. Specifically, it can be a bucket disclosed in application number 202321194317.4. Such a configuration is convenient for workers to enter and exit the barrel 30 and also convenient for transporting materials. The barrel 30 can also be a bucket disclosed in application number 202321200482.6. Such a configuration can reduce the labor intensity of the workers and improve production efficiency. The workers can select a suitable barrel 30 according to their needs.

[0039] Among them, there is 0.5m 3 , 1m 3 , 1.5m 3 , 2m 3 The barrel 30 of different volumes is provided. In the present application, the diameter of the wellbore 1 is set between 3m and 4.5m, and the volume is generally selected to be 0.5m 3The barrel body is 30, the barrel height is about 1100mm, the maximum outer edge size of the barrel is within 820mm, and the weight is between 188-225kg.

[0040] Specifically, in the present application, the first connecting rope 23 is a steel wire rope.

[0041] like Figure 2 As shown, at the tangent point A between the first connecting rope 23 and the lifting sheave 21 , the first connecting rope 23 is subjected to the largest static load, which includes the weight of the barrel 30 , the maximum cargo load and the weight of all lifting wire ropes from A to the barrel 30 .

[0042] According to Article 408 of the "Coal Mine Safety Regulations": The safety factor of steel wire ropes for various purposes must comply with the requirements of Table 9, and the minimum safety factor of a single-rope winding lifting device for lifting personnel and materials shall not be less than 9.

[0043] That is, Qtotal / Qstatic ≥ M;

[0044] Q static = Q capacity + Q load + PC;

[0045] Qtotal / Qcapacity+Qload+PC≥M;

[0046] At this time, the safety factor M=9, Qtotal / Qcapacity+Qload+PC≥9;

[0047] Where Qtotal is the total breaking tension of the first connecting rope 23, kg;

[0048] Q static - the maximum static load force on the first connecting rope 23 at the tangent point A, kg;

[0049] Q capacity——barrel body 30 weight, kg;

[0050] Q load - cargo weight, kg;

[0051] P——weight per meter of the first connecting rope 23, kg / m;

[0052] C——maximum hanging length of the first connecting rope 23, C=D+B, m;

[0053] M——safety factor of the first connecting rope 23;

[0054] D——lifting height, m;

[0055] B——Horizontal height of lifting wheel 21, m.

[0056] Article 408 of the Coal Mine Safety Regulations stipulates that the safety factor of steel wire ropes for various purposes must meet the requirements of Table 9. The minimum safety factor of steel wire ropes used for tank ropes, lifting wire ropes, suspension hoists 83, water pumps, drainage pipes, rock grabs, etc. shall not be less than 6. Similarly, according to Qtotal / Qstatic≥M, the calculation is carried out. If the safety factor M does not meet the requirements of Table 9, a steel wire rope with a larger diameter must be selected, and then calculated according to Qtotal / Qstatic≥M until it meets the requirements.

[0057] Furthermore, Article 417 of the Coal Mine Safety Regulations stipulates that the ratio of the minimum diameter of the hoisting device's sheave, drum, friction wheel, guide wheel 82 and guide roller to the wire rope diameter shall comply with the requirements of Table 13.

[0058] When selecting the lifting sheave 21, when the angle of the first connecting rope 23 surrounding the lifting sheave 21 is greater than 90°, the diameter of the lifting sheave 21 should be greater than or equal to 60 times the diameter of the first connecting rope 23. When the angle of the first connecting rope 23 surrounding the lifting sheave 21 is less than 90°, the diameter of the lifting sheave 21 should be greater than or equal to 40 times the diameter of the first connecting rope 23.

[0059] Specifically, in the present application, the first driving member 22 is a winch.

[0060] The diameter of the drum of the first driving member 22 is selected after the first connecting rope 23 is determined.

[0061] In order to ensure that the first connecting rope 23 does not generate a large bending stress when it is wound on the drum of the first driving member 22, the diameter D of the drum of the first driving member 22 is equal to the diameter d of the first connecting rope 23 and the diameter d of the thickest wire in the first connecting rope 23. 0 The ratio must meet the following requirements:

[0062] D≥60d, mm;

[0063] D≥900d 0 , mm;

[0064] According to the calculation results, select the standard roller diameter.

[0065] Further, in the present application, a track is provided at the bottom of the tunnel, and the transport member 40 is movably provided on the track.

[0066] In the process of deepening the shaft 1 of the mine, in order to ensure that the center line of the shaft 1 is accurate and does not deviate, it is necessary to regularly check the center line of the shaft 1. In this application, the wire-laying device disclosed in application number 2024212308915 is used to lay out the connecting rope. Such a setting can reduce the work intensity of the staff, improve the efficiency of laying and collecting the wires, and at the same time, can prevent the staff from shaking during the process of laying and collecting the wires, thereby ensuring the accuracy of the check.

[0067] Specifically, the underground mining and transportation device further includes a protection plate 51, which is used to be fixed on the inner wall of the shaft 1, and the protection plate 51 is arranged above the support platform 10. The protection plate 51 can block the gravel and the like falling from the outside of the shaft, and such arrangement can avoid personal injury safety accidents during the operation of the underground mining and transportation device, ensure the normal operation of the shaft 1 deepening work, and further ensure the safe production of the coal mine.

[0068] Furthermore, in the present application, a plurality of fixing holes are arranged on the inner wall of the wellbore 1, and the protection plate 51 has a plurality of protection beams, the protection beams correspond to the two fixing holes, and the two ends of the protection beams are respectively arranged in the corresponding two fixing holes.

[0069] The first driving member 22 is used to be placed in the horse head gate 2, and the underground mining and transportation device also includes a base 52. The base 52 is used to be fixed in the horse head gate 2, and the base 52 can support the first driving member 22.

[0070] The base 52 includes a plurality of load-bearing beams. During the processing of the base 52, the floor of the horse head gate 2 is leveled. The positions of the beam sockets of the base 52, the fixed beam sockets of the guide sheave 25, the lifting center line and the center line of the first drive member 22 are marked on the stone wall of the horse head gate 2 with paint. The positions of at least 3 groups of 6 beam sockets arranged parallel to each other are marked on both sides perpendicular to the lifting center line. Each beam socket is chiseled out on the stone wall of the bottom plate of the horse head gate 2, and at least 3 load-bearing beams are installed. The load-bearing beams are No. 20 I-beams. The load-bearing beams can be welded and connected into one piece with longitudinal beams according to the size of the base 52. After leveling and aligning the base 52, each beam socket is pre-embedded. After the pre-embedding period expires, the lifting center of the first drive member 22 is projected onto the base 52 to facilitate the installation of the first drive member 22, the guide sheave 25, etc.

[0071] By manufacturing, fixing and pre-embedding the base 52, the construction workload of the chamber and the wire rope way is reduced, the progress of equipment installation is greatly improved, and the construction period is shortened.

[0072] Specifically, in the prior art, during the deepening of the shaft 1, it is necessary to redevelop the chamber of the lifting equipment room and install electromechanical equipment. However, in the present application, the first driving member 22 is directly placed in the horse head door 2, which reduces the processing cost and avoids delays in the construction period.

[0073] Furthermore, a guide sheave 25 is provided in the horse head gate 2, and the first connecting rope 23 is connected to the barrel body 30 through the guide sheave 25 and the lifting sheave 21 in sequence.

[0074] like Figure 4 , Figure 5 and Figure 6 As shown, the inner wall of the shaft 1 is provided with a plurality of connection holes 101, the support platform 10 includes a plurality of support beams 11, the support beams 11 correspond to two connection holes 101, the two ends of the support beams 11 are respectively arranged in the corresponding two connection holes 101, and a fixing structure 60 is provided between the connection hole 101 and the support beam 11 to fix the support beam 11 in the connection hole 101, and the lifting sheave 21 is arranged between two adjacent support beams 11. Such a configuration facilitates the fixing of the support beam 11, and can ensure the stability of the support beam 11 fixed in the connection hole 101.

[0075] Specifically, when installing the support beam 11, it is first necessary to drill a plurality of connection holes 101 on the inner wall of the wellbore 1. In the present application, three groups of connection holes 101 are arranged on the inner wall of the wellbore 1, each group of connection holes 101 has two connection holes 101, and the support platform 10 includes three support beams 11, and the three support beams 11 are arranged in parallel.

[0076] Furthermore, the support beam 11 is an I-beam. The steel beam must be inspected and processed, the bent part must be straightened first, and pressure treatment should be adopted. Hammering or heating methods shall not be used. Steel beams with hard bends that cannot be straightened shall not be used. The curvature of the steel beam after straightening shall not exceed 0.5 / 1000 of the beam.

[0077] like Figure 5 and Figure 6 As shown, the fixing structure 60 includes a support member 61, a fixing member 62 and an inclined washer 63. The support member 61 is arranged in the connecting hole 101, and the supporting beam 11 is arranged on the support member 61. One end of the fixing member 62 is fixedly connected to one side of the supporting beam 11, and the other end of the fixing member 62 abuts against the inner wall of the connecting hole 101 to fix the supporting beam 11. The inclined washer 63 is arranged on the top of the fixing member 62, and the inclined washer 63 abuts against the inner wall of the connecting hole 101 to adjust the angle of the support member 61. With such an arrangement, the structure is simple and it is convenient to adjust the angle of the support member 61.

[0078] Specifically, in the present application, the fixing member 62 is a plate-shaped structure, which facilitates fixing the fixing member 62 .

[0079] Further, in the present application, the fixing structure 60 includes two inclined washers 63 and a flat washers 64. The two inclined washers 63 are located above the flat washers 64, and the inclined surfaces of the two inclined washers 63 are arranged opposite to each other. In this way, the support beam 11 is leveled in the above manner to ensure the stability of the support beam 11. At the same time, since the inclined washers 63 have a large bearing area and strength, they can bear a large weight, thereby preventing the support beam 11 from tilting in the subsequent process.

[0080] The fixing structure 60 further includes a cushion layer 65, which is disposed at the bottom of the connection hole 101, and the support member 61 is disposed on the cushion layer 65. The cushion layer 65 is a mortar cushion layer 65. Optionally, the support member 61 may be a refractory brick.

[0081] Specifically, when fixing the support beam 11, the size of the connection hole 101 should be determined according to the size of the support beam 11 used, the thickness of the inclined shim 63, the cushion layer 65, etc., and the size of the connection hole 101 along the radial direction should not be less than 500mm. The upper and lower surfaces of the connection hole 101 should be chiseled flat to facilitate the alignment and leveling of the support beam 11. First, a cushion layer 65 is laid on the lower surface of the connection hole 101, and the support member 61 is placed upright on the cushion layer 65. Then, the end of the support beam 11 is placed on the support member 61, and a flat shim 64 and a pair of inclined shims 63 are placed at the opening of the connection hole 101 and on the support beam 11. After adjusting the inclined shims 63 and leveling the support beam 11, a fixing member 62 can be welded on both sides of the support beam 11, and the flat shims 64 and the inclined shims 63 are welded and fixed at the same time to ensure that the support beam 11 does not deviate after being aligned. The plane of the support beam 11 must be horizontal, and the tolerance range must not exceed 2 / 1000.

[0082] According to actual conditions, the support member 61 may not be placed.

[0083] In order to allow concrete to smoothly enter the connecting hole 101, a gap of more than 50mm should be maintained between both sides of the support beam 11 and the two side walls and inner end surface of the connecting hole 101, and the depth should be more than 50mm from the connecting hole 101. A gap of more than 50mm should be maintained between the shim and the two side walls and inner end surface of the connecting hole 101, and the depth should be more than 50mm from the connecting hole 101. The connecting hole 101 should be pre-buried as required, and the concrete grade used to fill the connecting hole 101 should be higher than the standard and must be filled.

[0084] like Figure 4 As shown, there are a plurality of connecting beams 12 between two adjacent support beams 11, and there is an angle between the connecting beams 12 and the support beams 11, and the lifting sheave 21 is rotatably arranged between two adjacent connecting beams 12. Such an arrangement can further improve the stability of the support platform 10 and facilitate the fixing of the lifting sheave 21.

[0085] In the present application, the connection beam 12 is vertically arranged with the support beam 11. The connection beam 12 and the support beam 11 are fixed by welding.

[0086] The connecting beam 12 can be made of No. 9 or No. 11 I-beam for mining.

[0087] Specifically, when constructing the support platform 10 and the protection plate 51, the measurement and positioning work is first carried out, requiring the center line of the shaft 1, the lifting center line and its corresponding cross center line and the level elevation point to be accurately calibrated at the corresponding installation position. The marking of the calibration point should be reliable and eye-catching, and a calibrated point position map should be drawn for inspection and measurement.

[0088] According to the calculated height H, along the moving direction of the barrel 30, the connecting rope in the wire-releasing device disclosed in the application number 2024212308915 is released on the wall of the shaft 1, and the positions of multiple groups of connecting holes 101 arranged parallel to each other are marked perpendicular to both sides of the connecting rope, and the connecting holes 101 are chiseled out, and then the connecting beam 12 is installed. Finally, the position of the fixing hole is determined.

[0089] Furthermore, a tank ear is provided at the bottom of the barrel 30, and the lifting assembly 20 further includes a stabilizing sheave 24, a second driving member and a second connecting rope. The stabilizing sheave 24 is provided between two adjacent support beams 11. The second driving member is drivingly connected to one end of the second connecting rope, and the other end of the second connecting rope is fixed to the bottom of the shaft 1 through the stabilizing sheave 24 and the tank ear, that is, the second connecting rope is passed through the tank ear. Such a configuration can prevent the barrel 30 from shaking, and ensure that the barrel 30 can be normally raised and lowered.

[0090] In the present application, a counterweight is fixed to the other end of the second connecting rope, and the second driving member can tighten the second connecting rope, and the second connecting rope can play a guiding role, thereby ensuring the stability of the barrel body 30 during the up and down movement, and preventing the barrel body 30 from rotating during the up and down movement. When the wellbore 1 is deepening, the second driving member can release the second connecting rope of the corresponding length, thereby ensuring that the counterweight is located at the bottom of the wellbore 1.

[0091] Specifically, when the barrel body 30 is the bucket disclosed in Application No. 202321194317.4, the tank ear is the tank ear in the bucket disclosed in Application No. 202321194317.4, that is, the bottom of the barrel body 30 is provided with a guide part in the bucket disclosed in Application No. 202321194317.4.

[0092] Among them, in the present application, the second driving member is a hoist.

[0093] Specifically, in the present application, the lifting assembly 20 includes two stabilizing sheaves 24, and the lifting sheave 21 is arranged between the two stabilizing sheaves 24. Such an arrangement can ensure the stability of the barrel 30 during the up and down movement.

[0094] Furthermore, the underground mining and transportation device further includes a waste rock turning structure 71 and a chute 72. The waste rock turning structure 71 is fixed on the inner wall of the shaft 1, and the waste rock turning structure 71 can be connected to the barrel body 30 by driving, and the waste rock turning structure 71 can change the angle of the barrel body 30. The chute 72 is arranged on the waste rock turning structure 71, and the waste rock turning structure 71 can make the material in the barrel body 30 dump into the chute 72, and the transporting member 40 corresponds to the outlet of the chute 72, and the transporting member 40 transports the material through the chute 72. Such an arrangement is convenient for transporting materials and easy to operate.

[0095] Specifically, in the present application, the gangue turning structure 71, the chute 72 and the transport member 40 can adopt the structure of the bucket gangue turning device disclosed in the patent document with application number 202321259718.3, that is, the gangue turning structure 71 is equivalent to the mounting frame, turning part, support frame, pulley assembly, counterweight rope and counterweight block in the patent document with application number 202321259718.3. The chute 72 in the present application is the chute in the patent document, and the transport member 40 is the mine car in the patent document. With such a configuration, there is no need for the staff to repeatedly pick up and hook the barrel body 30, and it is only necessary to control the turning part to switch between the support position and the avoidance position, which reduces the labor intensity of the staff and improves the work efficiency of dumping coal gangue.

[0096] In the process of installing the rock turning structure 71, it is necessary to first determine the position of the mounting frame, which is perpendicular to the center line of the first connecting rope 23 and parallel to the axis of the lifting sheave 21. The position of the beam socket of the mounting frame is measured, and a cross line is marked on the well wall with paint, and the beam socket is chiseled out, and the mounting frame is pre-buried and fixed with cement mortar.

[0097] Then, the chute 72 is determined and installed.

[0098] like Figure 3 As shown, before the support platform 10 is installed, the height of the support platform 10 needs to be determined.

[0099] The height of the support platform 10 refers to the distance H from the horse head door 2 to the support platform 10, which can be calculated by the following formula:

[0100] H=h1+h2+h3+h4+0.5R,m;

[0101] Where h1 is the height of the gangue turning platform, that is, the vertical distance from the lowest point of the turning part to the track surface when the turning part is in the avoidance position;

[0102] h2——the height required for the barrel 30 to turn over, which is related to the dumping structure 71. When using manual dumping and automatic dumping structure 71, it is generally 1.5m;

[0103] h3——total length of the barrel 30, hook, connecting device and slide, that is, in actual working conditions, when the barrel 30 is fixed, the hook, connecting device and slide are usually arranged on the barrel 30, m;

[0104] h4——hoisting overwinding height. According to Article 407 of the Coal Mine Safety Regulations: the overwinding and overrelease distances of the vertical shaft hoisting device shall not be less than the values ​​listed in Table 8, and the value shall not be less than 4 meters;

[0105] R——nominal radius of the lifting sheave 21, m.

[0106] Furthermore, the shaft 1 has a first extension section 102 and a second extension section 103, the horse head gate 2 is arranged between the first extension section 102 and the second extension section 103, and the first extension section 102 is located above the second extension section 103. A manhole cover 53 is arranged at the connection between the second extension section 103 and the horse head gate 2, and the chute 72 is arranged on the manhole cover 53.

[0107] The underground mining and transportation device also includes a third driving member 81, a guide wheel 82, a hanging plate 83 and a third connecting rope 84. The third driving member 81 is arranged in the horse head gate 2. The guide wheel 82 is arranged at the connection between the second extension section 103 and the horse head gate 2. The hanging plate 83 is movably arranged in the second extension section 103, and the hanging plate 83 has an upper plate and a lower plate, the lower plate is used for transportation, and the upper plate is used for protection. Specifically, the staff can be located in the lower plate to carry out walling work, and the upper plate can protect the staff, thereby preventing the staff from being injured, and at the same time, construction materials such as stone can be placed on the upper plate.

[0108] Specifically, in the present application, a through hole is provided on the hanging plate, and the through hole penetrates the hanging plate in the vertical direction. The second connecting rope passes through the rope stabilizing sheave 24, the tank ear and the through hole in sequence and is connected to the counterweight block.

[0109] The third driving member 81 is drivingly connected to one end of the third connecting rope 84, and the other end of the third connecting rope 84 is connected to the hanging plate 83 through the guide wheel 82. The third driving member 81 drives the hanging plate 83 to move through the third connecting rope 84. In the present application, the third driving member 81 is a stable vehicle. In addition, the underground mining and transportation device includes two third driving members 81 and two third connecting ropes 84, and the two third driving members 81 and the two third connecting ropes 84 are arranged in a one-to-one correspondence, and the two third driving members 81 are respectively located on both sides of the shaft 1. Such an arrangement can ensure the stability of the hanging plate 83 during movement.

[0110] Among them, in the present application, the hanging plate 83 can be the lifting device disclosed in the application number 2024215470225. Such a configuration makes it easy for the staff to move to a suitable position, and then makes it easy for the staff to process the inner wall of the shaft 1, reducing the processing difficulty of the staff. At the same time, when the staff is working on the working surface of the shaft 1, that is, the bottom of the shaft 1, the lifting device can block the gravel and other materials that fall from the shaft 1 to avoid injury to the staff and ensure the safety of the staff. At the same time, the upper and lower layers of the hanging plate 83 can transport materials, which can reduce the occurrence of personal safety accidents caused by the imbalance of human-machine coordination due to frequent personnel operations and high labor intensity during the movement of the hanging plate 83, thereby ensuring the safety of the vertical shaft 1 construction.

[0111] Furthermore, in the present application, the third driving member 81 is also disposed on the base 52 .

[0112] like Figure 1 As shown, one end of the horse head gate 2 is connected to the main transport tunnel 3, and there is an angle between the horse head gate 2 and the main transport tunnel 3. The underground mining and transportation device also includes a transfer device 90, which is arranged at the connection between the horse head gate 2 and the main transport tunnel 3. The transfer device 90 can change the forward direction of the transport member 40. Such a configuration facilitates the transport member 40 to change direction, thereby reducing the size of the connection between the horse head gate 2 and the main transport tunnel 3, and facilitating the processing of the horse head gate 2 and the main transport tunnel 3.

[0113] Specifically, in the present application, the transfer device 90 may be the transfer device disclosed in the patent document with application number 2024217089365. The above structure can avoid widening the tunnel, thereby avoiding the installation of additional auxiliary tracks and switches, and thus avoiding the increase of engineering materials and construction period, reducing production costs, shortening the construction period, and improving production efficiency. At the same time, the above structure can avoid the reverse transportation of the mine car, ensure the coordination relationship between the mine car and the track, avoid the mine car from falling off the track, shorten the time required for the mine car to turn, reduce the difficulty of the mine car changing direction at the track intersection, and ensure normal production relations.

[0114] Furthermore, in the present application, during the operation of the underground mining and transportation device:

[0115] The first driving member 22 drives the barrel 30 to descend through the first connecting rope 23 to contain the coal gangue;

[0116] The first driving member 22 drives the barrel 30 to rise through the first connecting rope 23, and dumps the coal gangue into the transport member 40 through the gangue turning structure 71 and the chute 72;

[0117] The transporting member 40 moves to the transfer device 90, changes direction through the transfer device 90, and drives to the ground through the main transport tunnel 3 to transport the coal gangue out of the well;

[0118] The first driving member 22 drives the barrel 30 to descend through the first connecting rope 23 to hold the construction materials and place the construction materials at the bottom of the well;

[0119] The third driving member 81 drives the hanging plate 83 to move downward through the third connecting rope 84, and the hanging plate 83 is used to support the workers or construction materials.

[0120] Among them, in order to better understand this scheme, the construction process of underground mining and transportation equipment is:

[0121] 1. Conduct on-site survey, measurement and record the location and dimensions of the horse head gate 2, shaft 1 and main transport tunnel 3, and draw relevant dimension drawings of the on-site tunnels and shaft 1;
