Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, in particular to an underground conveying system based on high-speed acquisition equipment. Background Art

[0002] It is well known that the intelligent analysis system of high-speed acquisition equipment includes two parts: data acquisition and detection. Data acquisition and calculation judgment are performed through ADC (analog / digital converter or analog-to-digital converter, ADC refers to a device that converts continuously changing analog signals into discrete digital signals). The results can be stored locally or uploaded to the cloud. The production plan and parameters are adjusted according to the results by the host computer. The high-speed acquisition equipment intelligent analysis system is used to perform equipment startup analysis, no-load, load and overload operation analysis, equipment failure analysis, equipment operation status analysis, etc., to provide detailed operation data for equipment fault finding and abnormal problem analysis, and provide strong help for ensuring safe and efficient production.

[0003] The underground transportation system uses mechanical equipment to transport ore and waste rock from the mining exit point to the pit yard, skip mine bin or ground operation. There are two types of underground transportation: rail transportation and trackless transportation. Rail transportation usually uses electric locomotives to pull mine car trains along tracks to transport ore.

[0004] For example, the announcement number is CN219277480U, the announcement date is June 30, 2023, and the public name is a patent for an electric rack rail car for mining. This patent belongs to the technical field of mining engineering machinery and mining auxiliary transportation equipment, and is specifically a kind of electric rack rail car for mining. It adopts a single-section carriage design, including a chassis, a drive unit 1, a drive unit 2, a braking system and a rack rail. The specific structure is as follows: the drive unit 1, the drive unit 2, and the braking system are directly installed on the chassis, and the drive unit 1 and the drive unit 2 are respectively located at the front and rear of the chassis. The two drive units are respectively installed on the rack rail through the support guide wheel group, and the pin rail wheel on the drive unit is engaged with the tooth row on the rack rail to realize the operation of the electric rack rail car on the rack rail. This patent provides a mine electric rack rail car that can be used for underground auxiliary transportation of coal mines (mines), which can effectively improve the efficiency of underground transportation, while taking into account environmental protection and intelligent control, and realizing auxiliary transportation with few people and unattended operation.

[0005] The disadvantage of the prior art is that when the conveyor vehicle and the conveyor frame are loading the ore, the weight of the ore loaded in the conveyor frame cannot be kept constant, and the weight of the ore loaded in the conveyor frame fluctuates within a certain range. Since the weight of the ore loading fluctuates within a certain range, the weight of the ore loaded in some conveyor frames will be overloaded. Theoretically, if the ore in the conveyor frame does not need to be overloaded, it is necessary to load as little ore as possible in the conveyor frame, which will lead to a decrease in the transportation efficiency of the ore. Since the transportation efficiency of the ore needs to be ensured, overloading of the ore loaded in some conveyor frames is inevitable. Overloading of the ore in the conveyor frame will pose a safety hazard during transportation. Based on this, it is necessary to limit the conveyor frame to a certain extent to ensure the safety of the conveyor frame during transportation. Summary of the invention

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Fig.10 The present invention is further described in detail.

[0032] An embodiment provided by the present invention relates to an underground transportation system based on high-speed collection equipment, including a track 1, an electric locomotive 2 and a conveying vehicle 3, wherein the electric locomotive 2 and the conveying vehicle 3 are both arranged on the track 1, and the electric locomotive 2 is connected to the conveying vehicle 3, and also includes a collection mechanism and a limiting unit, wherein the conveying vehicle 3 is provided with a conveying frame 5 for carrying ore, and a limiting unit is respectively provided on both sides of the conveying vehicle 3, and the limiting unit is used to limit the side of the conveying frame 5, and the limiting unit is controlled to limit the conveying frame 5 based on the real-time load-bearing weight of the conveying frame 5 obtained by the collection mechanism.

[0033] Specifically, in this embodiment, the underground transportation system adopts rail transportation, and rail transportation is to transport ore through rail 1, electric locomotive 2 and conveying vehicle 3. The rail 1 is installed in the mining tunnel. The rail 1 is the rail on which the electric locomotive 2 and the conveying vehicle 3 run. A rack is arranged in the middle of the rail 1. The electric locomotive 2 provides meshing force for it through the rack to realize the operation of the electric locomotive 2 on the rail 1. The bottom ends of the electric locomotive 2 and the conveying vehicle 3 are evenly provided with rail wheels, and the rail wheels are rollingly arranged on the rail 1. The rolling of the rail wheels on the rail 1 realizes that the rail wheels drive the conveying vehicle 3 and the electric locomotive 2 to run on the rail 1. The number of conveying vehicles 3 is optional. The conveying vehicles 3 and The electric locomotives 2 are connected to each other, and the conveying vehicles 3 are connected to each other. The number of conveying vehicles 3 is selected according to the number of ores and the power of the electric locomotives 2. The number of conveying vehicles 3 is adapted to the power of the electric locomotives 2 and the number of ores. The above are all prior arts and will not be repeated here. In this embodiment, a limit frame 8 is provided on the conveying vehicle 3, and a plurality of first elastic members 9 are evenly arranged in the limit frame 8 on the conveying vehicle 3. A conveying frame 5 is slidably installed in the limit frame 8. The conveying frame 5 is placed on the first elastic member 9 (the first elastic member 9 is a component capable of telescopic reset, preferably a spring), and the conveying frame 5 is supported by the first elastic member 9.

[0034] In this embodiment, "controlling the limiting unit to limit the conveying frame 5 based on the real-time load-bearing weight of the conveying frame 5 obtained by the collecting mechanism" has two implementation modes: active and passive. The active mode means that the collecting mechanism is a gravity sensor (not shown in the figure), and a gravity sensor is provided at the exact center of the conveying vehicle 3. The limiting unit includes a driving member (not shown in the figure) and a limiting plate (not shown in the figure). The conveying vehicle 3 is provided with a driving member, and the output end of the driving member is connected to the limiting plate. When the conveying frame 5 is placed on the first elastic member 9, the gravity sensor and the conveying frame 5 abut against each other, and the conveying The conveying frame 5 compresses the first elastic member 9 to a certain extent, measures the displacement change and the extrusion pressure of the conveying frame 5 through the gravity sensor, and stores and analyzes the measured values ​​of the gravity sensor to obtain an analysis of the operation status of the conveyor vehicle 3. When the ore in the conveying frame 5 is overloaded, the limit plate is driven by the driving member (the output end of the driving member can perform linear reciprocating motion, and the output end of the driving member is rotationally connected to the swing plate 7) to move toward one end close to the conveying frame 5, so that the limit plate is pressed against the conveying frame 5, so that the limit plate can press against the conveying frame 5 to limit the position, thereby improving the stability of the conveying frame 5 in conveying the ore.

[0035] In contrast to the active type, in another passive implementation of this embodiment, the collection mechanism includes a mounting frame 6 and a swing plate 7. Two mounting frames 6 are symmetrically arranged on both sides of the conveying vehicle 3. A swing plate 7 is rotatably installed between the two mounting frames 6. A collecting frame 4 for collecting ore is arranged on the top of each of the two swing plates 7. Each swing plate 7 is a telescopic plate structure. Each swing plate 7 includes a bottom side with a groove 30 and a top side connected to the collecting frame 4. The top side of each swing plate 7 is slidably arranged in the groove 30. Each swing plate 7 slides in the groove 30 to adjust its length. The interior of the collecting frame 4 is a triangular structure, which is convenient for the collecting frame 4 to collect the ore. The collection mechanism includes a first wedge plate 10 and an arc rack 11. Two first wedge plates 10 are symmetrically installed at the bottom end of the conveying frame 5. The two first wedge plates 10 cooperate with the conveying vehicle 3 for use; one side of the bottom of each swing plate 7 is rotatably installed on the mounting frame 6. The bottom end of each swing plate 7 is installed A curved rack 11 is installed, and the center of the curved rack 11 coincides with the center of the rotation of the swing plate 7, and the end of the curved rack 11 rests on the first wedge plate 10; two slide grooves 12 are symmetrically provided on the conveying vehicle 3, and the two slide grooves 12 correspond to the parts arranged between the corresponding mounting frames 6, and a second wedge plate 13 is slidably installed in each of the two slide grooves 12, and the two second wedge plates 13 are wedge-shapedly matched with the corresponding first wedge plates 10, and the two second wedge plates 13 are connected to the inner walls of the corresponding slide grooves 12 by a second elastic member 14; each of the second wedge plates 13 is provided with an active tooth 15 at the top, and the active tooth 15 is meshed with the corresponding curved rack 11; the top of each swing plate 7 is rotatably connected to the bottom end of the collection frame 4 near the conveying frame 5, and the inclined surface of the inner wall of the top end of each collection frame 4 near the conveying frame 5 is an inclined surface inclined downward from the side close to the conveying frame 5 to the side away from the conveying frame 5.

[0036] Specifically, the middle part of the mounting frame 6 is in a disconnected state (that is, the mounting frame 6 is composed of two symmetrical flat plates, and the middle part is disconnected), the slide groove 12 is arranged on the disconnected part between the two flat plates of the mounting frame 6 on the conveying vehicle 3, and the swing plate 7 is a retractable plate. When the conveying frame 5 is placed in the limit frame 8, the conveying frame 5 squeezes the first elastic member 9, and the conveying frame 5 slides downward in the limit frame 8, and the conveying frame 5 drives the first wedge plate 10 to slide downward. Due to the mutual wedge-shaped cooperation between the first wedge plate 10 and the second wedge plate 13, the first wedge plate 10 pushes the second wedge plate 13 to slide in the slide groove 12 toward the outer side of the conveying vehicle 3, and the second wedge plate 13 stretches the second elastic member 14 (the second elastic member 14 is an original member that can be retracted and reset, preferably a spring). The second elastic member 14 is in a stretched state. Since the second wedge plate 13 is provided with an active tooth 15, and the active tooth 15 is meshed with the arc rack 11, the second wedge plate 13 drives the arc rack 11 and the swing plate 7 to rotate through the active tooth 15, so that the swing plate 7 drives the collecting frame 4 to rotate until the conveying frame 5 is filled with ore. The swing plate 7 drives the collecting frame 4 to press against the outer wall of the conveying frame 5. Due to the rotational connection between the collecting frame 4 and the swing plate 7, the collecting frame 4 can press against the outer wall of the conveying frame 5, so that the collecting frame 4 performs a certain pressing and positioning operation on the conveying frame 5, and when ore falls from the conveying frame 5, the collecting frame 4 can collect the fallen ore to prevent the ore from falling on the track 1, thereby reducing the waste of ore during transportation.

[0037] The conveyor vehicle 3 is driven by the electric locomotive 2 to move on the track 1, and the conveyor vehicle 3 conveys the ore in the conveyor frame 5. When the ore in the conveyor frame 5 is unevenly distributed, the conveyor frame 5 may tilt to one side, and the collecting frame 4 presses and positions the outer wall of the conveyor frame 5 to prevent the conveyor frame 5 from tilting too much. Preferably, a pressing block is provided on the outer wall of the swing plate 7, so that the collecting frame 4, the swing plate 7 and the pressing block can stably press and position the outer wall of the conveyor frame 5, thereby improving the stability of the conveyor frame 5 in conveying the ore.

[0038] When the ore falls from the conveyor vehicle 3, the ore falls into the collecting frame 4, and the collecting frame 4 collects the ore that falls from the conveyor vehicle 3 to prevent waste of the ore. The collecting frame 4 can collect the ore that falls into the conveying frame 5. When the ore is conveyed into the conveying frame 5, the first elastic member 9 can perform a certain buffering operation on the conveying frame 5.

[0039] The shortcoming of the prior art is that when the conveyor vehicle 3 and the conveyor frame 5 are loading the ore, the weight of the ore loaded in the conveyor frame 5 cannot be kept constant, and the weight of the ore loaded in the conveyor frame 5 fluctuates within a certain range. Since the weight of the ore loading fluctuates within a certain range, the weight of the ore loaded in some conveyor frames 5 will be overloaded. Theoretically, if the ore in the conveyor frame 5 does not need to be overloaded, it is necessary to load as little ore as possible in the conveyor frame 5, which will lead to a decrease in the transportation efficiency of the ore. Since it is necessary to ensure the transportation efficiency of the ore, overloading of the ore loaded in some conveyor frames 5 is inevitable. Overloading of the ore in the conveyor frame 5 will pose a safety hazard during transportation. Based on this, it is necessary to limit the conveyor frame 5 to a certain extent to ensure the safety of the conveyor frame 5 during transportation.

[0040] The beneficial effect of the present invention is that when it is necessary to transport the ore, after the ore is transported into the conveying frame 5, the conveying vehicle 3 is driven by the electric locomotive 2 to move on the track, and the real-time load-bearing weight of the conveying frame 5 is obtained by the collecting mechanism. When the load-bearing weight in the conveying frame 5 is overloaded, the outer wall of the conveying frame 5 is pressed and limited by the limiting unit, and the conveying vehicle 3 drives the ore in the conveying frame 5 to transport the ore. Since the limiting unit presses and limits the outer wall of the conveying frame 5, the safety of the conveying frame 5 during transportation is guaranteed.

[0041] The conveying frame 5 is then put on the conveying vehicle 3, and the conveying frame 5 is put on the conveying vehicle 3. The operation of the device is to unload the ore in the conveying frame 5 just taken out from the conveyor vehicle 3, so that the unloading time of the ore can be reduced and the conveying efficiency of the ore can be increased. The quality of the ore in the conveying frame 5 is different each time. The measurement values ​​of the displacement sensor and the force sensor are stored and analyzed by the intelligent analysis system of the high-speed acquisition equipment, and the analysis of the operation status of the conveyor vehicle 3 is obtained. The intelligent analysis system of the high-speed acquisition equipment analyzes the transportation of ores of various qualities, and obtains the operation analysis when the conveyor vehicle 3 is unloaded, loaded and overloaded. It is found that when the quality of the ore in the conveying frame 5 is in different ranges, the power of the electric locomotive 2 to pull the conveying frame 5 and the conveyor vehicle 3 is different, and it is found that the quality of the ore transported in the conveyor vehicle 3 and the conveying frame 5 is within the appropriate quality range, and the wear and transportation efficiency of the electric locomotive 2, the conveyor vehicle 3 and the conveying frame 5 reaches the ideal value (that is, the wear and transportation efficiency of the electric locomotive 2, the conveyor vehicle 3 and the conveying frame 5 reaches a balanced state).

[0042] The collecting units can be set on the four sides of the conveying vehicle 3, and the number of collecting units can be selected according to the running track of the track 1. When the track 1 is tilted upward (that is, the conveying vehicle 3 needs to go uphill), the collecting units can be set at the lower end of the conveying vehicle 3 when the track 1 is tilted upward. When the track 1 is tilted downward (that is, the conveying vehicle 3 needs to go downhill), the collecting units can be set at the lower end of the conveying vehicle 3 when the track 1 is tilted downward.

[0043] In another embodiment provided by the present invention, a plurality of pushing mechanisms are evenly arranged on the conveying vehicle 3, and each of the pushing mechanisms is in abutment with and cooperates with its corresponding collection frame 4. The pushing mechanism includes a straight plate 16, and the conveying vehicle 3 is provided with a straight plate 16, and a straight groove 17 is provided on the straight plate 16, and a square plate 18 is slidably installed in the straight groove 17. A magnet plate 19 is provided at one end of the square plate 18 close to the conveying frame 5, and the magnet plate 19 and the outer wall of the conveying frame 5 are mutually adsorbed. A card plate 20 is installed at one end of the square plate 18 away from the conveying frame 5, and a card slot 21 is provided on the card plate 20, and a lifting plate 22 is slidably installed in the card slot 21, and the lifting plate 22 and the bottom end of the collection frame 4 are in abutment with and cooperate with each other, and the lifting plate 22 and the inner wall of the card slot 21 are mutually adsorbed. The straight plate 16 is connected by a third elastic member 23, a first stopper 24 is provided at the bottom end of the lifting plate 22, a positioning plate 25 is installed on the top side wall of the straight plate 16, a clamping rod 26 is rotatably installed on the positioning plate 25, the clamping rod 26 and the inner wall of the straight plate 16 are connected by a fourth elastic member 27, a second stopper 28 is provided on the clamping rod 26, the second stopper 28 and the first stopper 24 abut against each other, the first stopper 24 and the second stopper 28 are both provided with inclined surfaces, the inclined surfaces on the first stopper 24 and the second stopper 28 are both inclined downward from one end of the lifting plate 22 to one end of the clamping rod 26, an unlocking block 29 is provided on the clamping plate 20 at one side of the bottom end of the clamping slot 21, and the ends of the unlocking block 29 and the clamping rod 26 are wedge-shaped and matched with each other.

[0044] Specifically, when the conveyor vehicle 3 drives the conveyor frame 5 to the unloading position, the staff takes the conveyor frame 5 out of the limit frame 8 on the conveyor vehicle 3 by means of a crane or other lifting equipment. In the process of taking the conveyor frame 5 out of the conveyor vehicle 3, (1) when the conveyor frame 5 is taken out of the limit frame 8 on the conveyor vehicle 3, the first elastic member 9 on the conveyor vehicle 3 recovers its original length, and the conveyor frame 5 no longer squeezes the first elastic member 9. Under the pulling back action of the second elastic member 14, the second elastic member 14 drives the second wedge plate 13 in the slide groove. 12 slides inwardly toward one end of the conveying frame 5, and the second wedge plate 13 drives the arc rack 11 and the swing plate 7 to rotate through the active tooth 15, so that the swing plate 7 drives the collecting frame 4 to press against the top side wall of the conveying frame 5; at the same time, the conveying frame 5 drives the square plate 18 to slide along the track of the straight groove 17 through the magnet plate 19, so that the magnet plate 19 drives the square plate 18 to slide upward, and the square plate 18 drives the card plate 20 to slide upward, and the card plate 20 drives the lifting plate 22 to slide toward one end of the collecting frame 4, so that when the card plate 20 and the lifting plate 22 slide upward, The card plate 20 and the lifting plate 22 drive the collection frame 4 to slide upward, and the collection frame 4 drives the swing plate 7 to stretch, so that the overall length of the swing plate 7 is increased, so that the top of the collection frame 4 overlaps the top of the conveying frame 5, and the lifting plate 22 drives the first stopper 24 and the second stopper 28 to abut against each other. Because the second stopper 28 abuts and positions the first stopper 24, and under the elastic force of the fourth elastic member 27 (the fourth elastic member 27 is an original member that can be telescopically reset, preferably a spring), the card rod 26 and the second stopper 28 abut the first stopper 24. The block 24 provides a stable abutting operation. When the lifting plate 22 slides toward the end away from the conveying vehicle 3, the lifting plate 22 squeezes the third elastic member 23 (the third elastic member 23 is an original member capable of telescopic reset, preferably a spring); that is, when the first elastic member 9 returns to its original length, the third elastic member 23 is in a compressed state under the mutual abutment of the first stop block 24 and the second stop block 28, and the card plate 20 drives the unlocking block 29 to move to a position where it abuts against the bottom end of the card rod 26.(2) When the card plate 20 drives the unlocking block 29 to move to a position where it abuts against the bottom end of the card rod 26, the conveying frame 5 continues to drive the square plate 18 to slide along the track of the straight groove 17 through the magnet plate 19, so that the magnet plate 19 drives the square plate 18 to slide away from the end of the conveying vehicle 3, and the square plate 18 drives the card plate 20 to slide toward the end of the collection frame 4, and the card plate 20 drives the lifting plate 22 to slide toward the end of the collection frame 4. The card plate 20 drives the unlocking block 29 to push the card rod 26 to rotate, so that the card rod 26 drives the second block 28 to release the tight operation on the first block 24. At this time, the first block 24 and the lifting plate 22 are no longer pressed by the second stopper 28. Under the rebound effect of the third elastic member 23, the elastic force stored in the third elastic member 23 acts on the lifting plate 22 instantaneously, so that the top of the lifting plate 22 pushes the collecting frame 4 to rotate, and at the same time, the collecting frame 4 drives the swing plate 7 to stretch to a certain extent. Since the top side wall of the collecting frame 4 is against the conveying frame 5, when the lifting plate 22 pushes the collecting frame 4, the collecting frame 4 is forced to rotate. Since the interior of the collecting frame 4 is a triangular structure, the ore collected in the collecting frame 4 rolls from the collecting frame 4 to the conveying frame 5 (such as; Fig. 9 As shown in the figure, when the conveying frame 5 is taken out from the conveying vehicle 3, the ore dropped therefrom can be recycled, thereby reducing the waste of ore; (3) when the ore falls from the collecting frame 4 into the conveying frame 5, that is, after the elastic force of the third elastic member 23 completes the pushing operation of the lifting plate 22, the magnet plate 19 and the conveying frame 5 are separated from each other, and the conveying frame 5 is taken out from the conveying vehicle 3, the magnet plate 19 drives the square plate 18 to slide along the trajectory of the straight groove 17 away from the end of the conveying vehicle 3, the square plate 18 drives the card plate 20 to slide toward the end close to the conveying vehicle 3, and the card plate 20 drives the lifting plate 22 to move closer to the end of the conveying vehicle 3. When one end of the conveying vehicle 3 slides, causing the card plate 20 and the lifting plate 22 to slide toward one end of the conveying vehicle 3, the card plate 20 and the lifting plate 22 drive the collecting frame 4 to slide toward one end of the conveying vehicle 3, and the lifting plate 22 slides in the card slot 21 under the pulling action of the third elastic member 23 to the position where the first stop block 24 and the second stop block 28 abut against each other, and the swing plate 7 shrinks to its original length, so that the collecting frame 4 on the swing plate 7 abuts against the top of the card plate 20 and the lifting plate 22; repeating the above operation can realize the efficient transportation of ore and the analysis of the operation status of the conveying vehicle 3 during transportation.

[0045] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
