Description

Technical Field

[0001] The present invention belongs to the technical field of mining machinery and relates to a conveying and hoisting device for deep inclined shaft mining. Background Technique

[0002] Mining engineering is divided into coal mining and non - coal mining. Mining is the technology and science of extracting mineral resources from within the earth's crust or on the surface. Generally, it refers to the mining of metal or non - metal ore deposits. Broadly speaking, mining also includes the extraction and beneficiation of coal and petroleum. Its essence is a process of selective collection and transportation of materials. The mining industry is an important raw material extraction industry. For example, metal ores are the main raw materials for the metallurgical industry, non - metal ores are chemical raw materials and building materials, and coal and petroleum are important energy sources. Most ores need to be concentrated by ore dressing before being used as industrial raw materials. Mining generally adopts the vertical shaft or inclined shaft method.

[0003] An inclined shaft refers to a well with an inclined angle in drilling engineering. The wellhead and the design target point are not on the same vertical line, but according to human needs, the well deviates from the wellhead vertical line by a certain distance in a given direction.

[0004] With the continuous improvement of exploration and development requirements, the proportion of directional wells, horizontal wells, branched wells, etc. in the drilled wells is increasing. There are inclined shaft sections with different well inclinations in these wells.

[0005] The surface wellhead is centralized, occupying a small area, reducing the surface oil gathering pipelines, simplifying the well site setting, and facilitating centralized management; the inclined shaft can be drilled from the coast or seawall to the offshore oil and gas traps at a certain water depth, or it can avoid important buildings, mountains, paddy fields, etc. on land. The well site is set at the edge of the structure, and the oil is produced by directional inclined shafts; directional inclined shafts can also be formed by sidetracking in old wells, which can save costs and carry out rolling exploitation.

[0006] However, the existing inclined shaft conveying and hoisting cannot effectively protect the inclined minerals. At the same time, there are two types of materials in mining, namely ore and waste rock, lacking a distribution function and without protective equipment.

[0007] For deep inclined shafts, we have proposed a two - stage inclined shaft with different inclinations, where the inclination of the lower inclined shaft is not less than 47 degrees. However, the existing inclined shaft hoisting and transportation equipment cannot adjust the angle of the track, cannot be changed according to on - site requirements, is prone to collision with the terrain, causing damage, increasing the processing cost, unable to achieve rapid reciprocating transportation, with a long waiting time, reducing the work efficiency, and prolonging the working hours.

[0008] After retrieval, as disclosed in a Chinese patent document, there is an ore lifting conveyor [Application No.: CN202022315969.1]. This ore lifting conveyor includes a housing, on the outer side of which a first motor is fixedly installed. A driving roller is fixedly installed on the rotating shaft of the first motor. The driving roller is rotatably connected to the housing. A rotating roller is fixedly sleeved on the outer side of the driving roller. A conveyor belt is sleeved on the outer side of the rotating roller. Baffles are arranged on the conveyor belt. A spray chamber is fixedly installed inside the housing. A water pump is fixedly installed at the upper end of the spray chamber. A water inlet pipe is arranged inside the water pump, and a drain pipe is arranged on the water pump. Although this conveyor can provide a certain humidity for the ore through the contact between the atomized water and the ore, so that the dust adheres to the ore, thus achieving the effect of preventing the dust from flying everywhere, it still does not have a distribution function and protective equipment and cannot achieve rapid reciprocating transportation.

[0009] After retrieval, as disclosed in a Chinese patent document, there is an inclined shaft lifting and transporting device for copper mine mining [Application No.: CN202020098314.0]. This lifting and transporting device includes a square frame, on the top of which a control mechanism is installed. The control mechanism includes a bracket, a first motor, a threaded rod and a sleeve plate. The left side of the bracket is fixedly connected to the right top of the square frame. The inner wall of the bracket is fixedly connected to the outer wall of the first motor. The output end of the first motor is fixedly connected to the top of the threaded rod. The outer wall of the threaded rod is threadedly connected to the inner wall of the sleeve plate. Although the angle adjustment of the device is realized, damage is avoided and the processing cost is reduced, it still does not have a distribution function and protective equipment and cannot achieve rapid reciprocating transportation.

[0010] Based on this, we propose a conveying and lifting device for deep inclined shaft mining, which can be used for two deep inclined shafts with different inclination degrees; realize the synchronous reverse rotation of two winding mechanisms to form reciprocating and non-stop feeding; realize the sorting and conveying of ore and waste rock with higher efficiency; cooperate with several anti-runaway mechanisms to block the transport vehicle and avoid damage. Summary of the Invention

[0011] The purpose of the present invention is to address the above problems existing in the prior art and propose a conveying and lifting device for deep inclined shaft mining. The technical problem to be solved by this invention is: how to achieve stable, safe and rapid reciprocating conveying and lifting of stones through a two-stage deep inclined shaft, and can distribute waste rock and ore with higher discharging efficiency.

[0012] The purpose of the present invention can be achieved by the following technical solutions:

[0013] A conveying and hoisting device for deep inclined shaft mining, comprising two symmetrically arranged winding mechanisms and a reversing mechanism arranged between the two winding mechanisms. A speed regulator is arranged between the reversing mechanism and one of the winding mechanisms. An ore hoist is arranged on the lower side of the reversing mechanism. The winding mechanisms are located at the discharge ports of the inclined shafts. Adjusting tracks are arranged on the side parts of the winding mechanisms. The adjusting tracks are arranged at the bottom of the inclined shafts. Transporters are arranged on the adjusting tracks. The transporters are connected to the steel ropes of the corresponding winding mechanisms. A number of anti-runaway mechanisms are arranged above the adjusting tracks. The anti-runaway mechanisms are arranged at the top of the inclined shafts. A waste rock conveyor is arranged at the lower part of the ore hoist.

[0014] The working principle of the present invention: This deep inclined shaft is composed of two inclined shafts with different inclination degrees. The two adjusting tracks are symmetrically arranged at the bottoms of the two inclined shafts with different inclination degrees. The transporter on one adjusting track is located at the bottom, that is, the feeding end, and the transporter on the other adjusting track is located at the top, that is, the discharging end. Adjust the rotation speed of the speed regulator so that the rotation speeds of the two winding mechanisms are the same. The two winding mechanisms cooperate with the reversing mechanism so that the rotation directions of the two winding mechanisms are opposite, that is, pull out the transporter on one adjusting track. The transporter is filled with stones, and at the same time, send down the transporter on the other adjusting track, an empty vehicle. The transporter filled with stones is transported to the discharging end for discharging. If it is waste rock, control the transporter to discharge to the outside. The waste rock falls on the waste rock conveyor and is then transported out. If it is ore, control the transporter to discharge to the inside. The ore falls on the ore hoist and is then transported out, forming a reciprocating and uninterrupted feeding;

[0015] During the conveying process, if a runaway occurs, that is, the transporter is disconnected from the steel rope connection of the corresponding winding mechanism, the anti-runaway mechanism above the corresponding adjusting track works to block the transporter and avoid damage to personnel, the transporter or other equipment.

[0016] The winding mechanism includes a winding frame. A steel rope seat is arranged on the upper side of the side part of the winding frame. A guide wheel is rotatably arranged on the steel rope seat. The upper end of the winding frame is rotatably provided with two symmetrically arranged first bearing seats at both ends. A winding drum is arranged between the two first bearing seats. A steel rope is arranged on the winding drum. The steel rope passes through the guide wheel. A winding motor is fixed on the winding frame of one of the winding mechanisms. The rotating shaft of the winding motor is in transmission connection with the rotating shaft of the winding drum of this winding mechanism.

[0017] With the above structure, the steel rope is connected to the transporter. The rotating shaft of the winding motor drives the rotating shaft of the winding drum of this winding mechanism to rotate. At the same time, through the cooperation of the reversing mechanism and the speed regulator, drive the rotating shaft of the winding drum of the other winding mechanism to rotate in the opposite direction, so as to control the winding and releasing of the steel rope, and be used to pull out and lower the transporter. The steel rope passes through the guide wheel to ensure that the steel rope always outputs and retracts from the guide wheel, ensure that the pulling direction of the transporter remains unchanged, the pulling is stable, and avoid the inclination of the transporter.

[0018] The reverse mechanism includes a reverse frame. At the upper end of the reverse frame, second bearing seats with symmetric ends are rotatably provided. Inside one of the second bearing seats, an input shaft is provided. One end of the input shaft is in transmission connection with the rotating shaft of one of the winding drums. At the other end of the input shaft, an internal gear cover is provided. Inside the internal gear cover, internal teeth are provided. Inside the other second bearing seat, an output shaft is provided. At one end of the output shaft, a driven gear is provided. At one end of the output shaft, a driven gear is provided. A fixing plate is fixed to the side of the reverse frame. The speed governor is fixed to the upper end of the fixing plate. The other end of the output shaft is in transmission connection with the rotating shaft at one end of the speed governor. The rotating shaft at the other end of the speed governor is in transmission connection with the rotating shaft of the other winding drum. A limiting cylinder is fixed to the side of the other second bearing seat. The output shaft penetrates through the limiting cylinder. At the end of the limiting cylinder, a number of reverse gears are rotatably provided. The reverse gears are respectively engaged with the internal teeth and the driven gear.

[0019] With the above structure, the rotating shaft of the actively rotating winding drum drives the rotation of the input shaft, thereby driving the rotation of the internal gear cover. The internal teeth of the internal gear cover are engaged with the reverse gears. The internal teeth drive the reverse gears to rotate in the same direction around the end of the limiting cylinder. The reverse gears are respectively engaged with the driven gears. The reverse gears drive the driven gears to rotate in the reverse direction, thereby driving the output shaft to rotate in the reverse direction. The output shaft drives the speed governor to rotate. The speed governor adjusts the conveying speed, so that the speed governor drives the rotating shaft of the other winding drum to rotate in the same speed and in the reverse direction.

[0020] The waste rock conveyor includes a horizontal conveying section. On both sides of the horizontal conveying section, feeding and discharging conveying sections are provided. The heights of the feeding and discharging conveying sections on both sides are different. The lower side is the feeding section, and the higher end is the discharging section. On the side of each feeding and discharging conveying section, a feeding cylinder is provided. The two feeding cylinders are located outside the two adjusting tracks. Inside the feeding cylinder, a number of first buffer plates are provided. Below the horizontal conveying section and the feeding and discharging conveying sections, a lifting frame is provided.

[0021] With the above structure, the lifting frame is fixed at the discharge point of the inclined shaft. The transport vehicle dumps the waste rock to both sides and pours it into the two feeding cylinders. The waste rock will fall down after being buffered by a number of first buffer plates to protect the feeding cylinders. The heights of the feeding and discharging conveying sections on both sides are different. The lower side is the feeding section, which conveys the waste rock to the horizontal conveying section. The horizontal conveying section conveys the waste rock to the discharging section, and the discharging section sends out the waste rock.

[0022] The ore hoist includes a lifting frame. At the feeding end of the lifting frame, a guiding hopper is provided. The guiding hopper is located directly above the horizontal conveying section and inside the two adjusting tracks. Below the lifting frame and the guiding hopper, support frames are provided. Inside the lifting frame, a lifting track is provided. On the side of the lifting frame, a lifting motor is provided. The rotating shaft of the lifting motor is in transmission connection with one of the rotating shafts of the lifting track. Inside the guiding hopper, a number of second buffer plates are provided.

[0023] With the above structure, the support frame is fixed at the discharge point of the inclined shaft and can adjust the inclination angle of the lifting frame, that is, the conveying height and angle. The transport vehicle dumps the ore inward and pours it into the inside of the guide hopper. The ore will fall down after being buffered by a number of second buffer plates to protect the guide hopper. The rotating shaft of the lifting motor drives one of the rotating shafts of the lifting track to rotate and send out the ore.

[0024] The adjusting track includes two track bodies with different inclinations. The inclination of the lower track body is greater than that of the upper track body. The two track bodies are fixed at the bottoms of two inclined shafts with different inclinations. There is a member body with the same angle as that between the two track bodies between the two track bodies. In the middle of the upper side of the member body, there are symmetric connecting plates. Installation slot holes are provided on the connecting plates. Installation screw holes are provided at the adjacent ends of the two track bodies. The installation screw holes correspond to the positions of the installation slot holes.

[0025] With the above structure, the two track bodies are fixed at the bottoms of two inclined shafts with different inclinations according to the inclination of the inclined shaft. According to the angle between the two track bodies, a member body with a suitable specification is selected and inserted between the two track bodies. The installation screw holes cooperate with the installation slot holes, and the locking bolts are installed to install the member body, so that the member body and the two track bodies have a smooth transition and form a seamless connection, facilitating the smooth movement of the transport vehicle on the adjusting track. The inclination of the lower track body is greater than that of the upper track body, which can meet the requirements of deep inclined shafts.

[0026] The transport vehicle includes a vehicle frame. Four symmetrically arranged wheels are provided on the lower side of the vehicle frame. The wheels are arranged on the track body. A tension sensor is provided at the end of the vehicle frame. The tension sensor is connected to the steel rope of the corresponding winding mechanism. A tipping motor, two symmetrically arranged corresponding rotating frames and a grid baffle are successively provided at the upper end of the vehicle frame. A loading hopper is rotatably arranged between the two rotating frames. The main shaft of the tipping motor is in transmission connection with the rotating shaft of the loading hopper.

[0027] With the above structure, the steel rope of the corresponding winding mechanism pulls the tension sensor, and then pulls the vehicle frame through the tension sensor. The wheels under the vehicle frame move smoothly along the adjusting track. When moving to the discharge point, the tipping motor drives the rotating shaft of the loading hopper to rotate, so that the loading hopper rotates laterally and dumps the waste stone and ore inside. During the conveying process, if a runaway occurs, the tension of the tension sensor instantly becomes zero, and the anti-runaway mechanism works and blocks on the grid baffle of the transport vehicle to avoid damage to personnel, the transport vehicle or other equipment.

[0028] The anti - runaway mechanism includes a cross - frame which is fixed at the top of the inclined shaft. A limit frame and two hinge frames are arranged on the lower side of the cross - frame. The limit frame is located between the two hinge frames. A turning frame is rotatably arranged between the two hinge frames. An anti - runaway motor is arranged on one of the hinge frames. The main shaft of the anti - runaway motor is in transmission connection with the rotating shaft of the turning frame. A buffer pad is arranged on the side of the turning frame.

[0029] With the above structure, when the turning frame is in the initial position, the turning frame is horizontally arranged and the buffer pad faces upward. If a runaway occurs, the tension of the tension sensor instantly becomes zero. The main shaft of the anti - runaway motor drives the rotating shaft of the turning frame to rotate, that is, drives the turning frame to rotate 90 degrees. The upper end of the turning frame abuts against the limit frame, the buffer pad is vertically arranged, and the grid baffle of the transport vehicle abuts against the buffer pad to ensure that the transport vehicle stops moving.

[0030] Compared with the prior art, the conveying and hoisting device for deep inclined - shaft mining has the following advantages:

[0031] The adjustable track realizes the use for two inclined shafts with different inclination degrees through the cooperation of the track body and the connecting member, meeting the conveying requirements of deep - mining.

[0032] Through the cooperation of the two winding mechanisms, the reverse mechanism and the speed regulator, the two winding mechanisms are synchronously rotated in opposite directions, and cooperate with the transport vehicle to meet the requirement of forming a reciprocating and non - intermittent feeding.

[0033] Through the cooperation of the transport vehicle with the ore hoist and the waste - rock conveyor, the ore and the waste rock are separately conveyed, sorted and conveyed, with higher efficiency.

[0034] By setting a tension sensor between the transport vehicle and the winding mechanism, the anti - runaway treatment can be carried out in time.

[0035] Through the cooperation of several anti - runaway mechanisms, when a runaway occurs, the anti - runaway mechanism above the corresponding adjustable track works to block the transport vehicle, avoiding damage to personnel, the transport vehicle or other equipment.

[0049] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0050] Such as Figures 1-12As shown, the conveying and hoisting device for deep inclined shaft mining includes two symmetrically arranged winding mechanisms 2 and a reversing mechanism 7 arranged between the two winding mechanisms 2.

The anti-runaway mechanisms 6 are arranged at the top of the inclined shaft. A waste rock conveyor 3 is provided at the lower part of the ore hoist 1.

[0051] The present invention relates to a deep inclined shaft having two sections with different inclinations. The two adjusting rails 5 are symmetrically arranged at the bottom of the two sections with different inclinations. The transport trolley 4 on one adjusting rail 5 is at the bottom (feeding end), and the transport trolley 4 on the other adjusting rail 5 is at the top (discharging end). The speed of the speed regulator 13 is adjusted so that the speeds of the two winding mechanisms 2 are the same. The two winding mechanisms 2 cooperate with the reversing mechanism 7 so that the directions of the two winding mechanisms 2 are opposite, that is, the transport trolley 4 on one adjusting rail 5 is pulled out (the transport trolley 4 is full of stones) and the transport trolley 4 on the other adjusting rail 5 is sent down at the same time. The transport trolley 4 filled with stones is transported to the discharging end for unloading. If it is waste rock, the transport trolley 4 is controlled to unload to the outside, and the waste rock falls on the waste rock conveyor 3 and is then transported out. If it is ore, the transport trolley 4 is controlled to unload to the inside, and the ore falls on the ore elevator 1 and is then transported out, forming a reciprocating non-intermittent feeding.

At the same time, it cooperates with the speed regulator 13 through the reversing mechanism 7 to drive the rotating shaft of the winding drum 11 of the other winding mechanism 2 to rotate in the opposite direction, thereby controlling the winding and releasing of the steel rope, which is used to pull out and put down the transport vehicle 4.

The wheels 39 below the vehicle frame 38 move smoothly along the adjustment track 5. When moving to the discharging position, the tipping motor 41 drives the rotating shaft of the loading hopper 43 to rotate, so that the loading hopper 43 rotates laterally to pour out the internal waste rocks and ores. During the conveying process, if a runaway occurs, the tension of the tension sensor 40 instantly becomes zero, then the anti-runaway mechanism 6 works and blocks on the grid baffle 44 of the transport vehicle 4 to avoid damage to personnel, the transport vehicle 4 or other equipment.

[0065] The anti-runaway mechanism 6 includes a cross frame 45. The cross frame 45 is fixed at the top of the inclined shaft. A limit frame 47 and two hinge frames 46 are provided on the lower side of the cross frame 45. The limit frame 47 is located between the two hinge frames 46. A turning frame 48 is rotatably arranged between the two hinge frames 46. An anti-runaway motor 50 is provided on one of the hinge frames 46. The main shaft of the anti-runaway motor 50 is in transmission connection with the rotating shaft of the turning frame 48. A buffer pad 49 is provided on the side of the turning frame 48;

[0066] When the turning frame 48 is in the initial position, the turning frame 48 is horizontally arranged and the buffer pad 49 faces upward. If a runaway occurs, the tension of the tension sensor 40 instantly becomes zero. The main shaft of the anti-runaway motor 50 drives the rotating shaft of the turning frame 48 to rotate, that is, drives the turning frame 48 to rotate 90 degrees. The upper end of the turning frame 48 abuts against the limit frame 47, the buffer pad 49 is vertically arranged, and the grid baffle 44 of the transport vehicle 4 abuts against the buffer pad 49 to ensure that the transport vehicle 4 stops moving.

[0067] The working principle of the present invention:

[0068] This deep inclined shaft is composed of two inclined shafts with different inclination degrees. According to the inclination degrees of the inclined shafts, the two track bodies 34 are fixed at the bottoms of the two inclined shafts with different inclination degrees. According to the angle between the two track bodies 34, a suitable specification of the component body 35 is selected. The component body 35 is inserted between the two track bodies 34. The installation screw holes cooperate with the installation groove holes 37, and the locking bolts are locked to install the component body 35, so that the component body 35 and the two track bodies 34 have a smooth transition and form a seamless connection, which is convenient for the transport vehicle 4 to move smoothly on the adjustment track 5. The inclination degree of the lower track body 34 is greater than that of the upper track body 34, that is, it can meet the requirements of the deep inclined shaft;

[0069] One transport vehicle 4 on the adjustment track 5 is located at the bottom (feeding end), and another transport vehicle 4 on the adjustment track 5 is located at the top (discharging end). Adjust the rotation speed of the speed governor 13 so that the rotation speeds of the two winding mechanisms 2 are the same;

[0070] The rotating shaft of the actively rotating winding drum 11 drives the rotation of the input shaft 17, thereby driving the rotation of the internal tooth cover 18. The internal teeth 21 of the internal tooth cover 18 mesh with the reverse gears 23. The internal teeth 21 drive the reverse gears 23 to rotate in the same direction around the end of the limiting cylinder 19. The reverse gears 23 are respectively meshed with the driven gears 22. The reverse gears 23 drive the driven gears 22 to rotate in the reverse direction, thereby driving the output shaft 20 to rotate in the reverse direction. The output shaft 20 drives the speed governor 13 to rotate. The speed governor 13 adjusts the conveying speed so that the speed governor 13 drives the rotating shaft of another winding drum 11 to rotate in the same speed and in the reverse direction;

[0071] That is, pull out the transport vehicle 4 on one adjustment track 5 (the transport vehicle 4 is filled with stones), and at the same time lower the transport vehicle 4 on the other adjustment track 5 (empty vehicle). The transport vehicle 4 filled with stones is conveyed to the discharging end for discharging;

[0072] If it is waste stone, the tipping motor 41 drives the rotating shaft of the loading hopper 43 to rotate, so that the loading hopper 43 discharges to the outside. The waste stone is poured into the two feeding cylinders 25. The waste stone will buffer and fall through a number of first buffer plates 28 to protect the feeding cylinders 25. The heights of the feeding and discharging conveying sections 24 on both sides are different. The lower side is the feeding section. The feeding section conveys the waste stone to the horizontal conveying section 26. The horizontal conveying section 26 conveys the waste stone to the discharging section. The discharging section sends out the waste stone;

[0073] If it is ore, the tipping motor 41 drives the rotating shaft of the loading hopper 43 to rotate, so that the loading hopper 43 discharges to the inside and is poured into the guide hopper 32. The ore will buffer and fall through a number of second buffer plates 33 to protect the guide hopper 32. The rotating shaft of the lifting motor 30 drives the rotation of one of the rotating shafts of the lifting crawler 31 to send out the ore;

[0074] Cooperate to form reciprocating and non-stop feeding;

[0075] During the conveying process, if a running-away occurs, that is, the transport vehicle 4 is separated from the steel wire connection of the corresponding winding mechanism 2, the tension of the tension sensor 40 instantly becomes zero, and the anti-running-away mechanism 6 above the corresponding adjustment track 5 works. The main shaft of the anti-running-away motor 50 drives the rotation of the rotating shaft of the flipping frame 48, that is, drives the flipping frame 48 to rotate 90 degrees. The upper end of the flipping frame 48 abuts against the limiting frame 47. The buffer pad 49 is vertically arranged. The grid baffle 44 of the transport vehicle 4 abuts against the buffer pad 49 to ensure that the transport vehicle 4 stops moving and avoid damage to personnel, the transport vehicle 4 or other equipment.

[0076] In summary, the adjusting track 5 cooperates with the connecting member through the track body 34 to be used for two inclined shafts with different inclinations, meeting the conveying requirements of deep mining;

[0077] Through the cooperation of the two winding mechanisms 2, the reversing mechanism 7 and the speed governor 13, the two winding mechanisms 2 rotate synchronously and in opposite directions, and cooperate with the transport vehicle 4 to meet the formation of reciprocating and non-stop feeding;

[0078] Through the cooperation of the transport vehicle 4 with the ore hoist 1 and the waste rock conveyor 3, the ore and the waste rock are separately transported and sorted for transportation, with higher efficiency;

[0079] By arranging a tension sensor 40 between the transport vehicle 4 and the winding mechanism 2, the anti-runaway treatment can be carried out in a timely manner;

[0080] Through the cooperation of a number of anti-runaway mechanisms 6, when a runaway occurs, the anti-runaway mechanism 6 above the corresponding adjusting track 5 works to block the transport vehicle 4, avoiding damage to personnel, the transport vehicle 4 or other equipment.

Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
