Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of open-pit mine cars, and specifically refers to a mine car loading monitoring device and an alignment method. Background Art
[0002] A mining truck is a heavy-duty dump truck used in open-pit mines to complete rock and earth stripping and ore transportation tasks. Its working characteristics are short transportation distance and heavy load. At present, large shovels are mostly used to load mine cars. Usually, the volume of the bucket of such shovels is equivalent to the volume of the loading compartment of the mine car. Therefore, the shovel can fill the mine car with a single shovel, which greatly improves the loading efficiency. However, the problem with this loading method is that the bucket of the shovel is too large, and the size of the compartment of the mine car is different depending on the model. Therefore, during the loading process, it cannot be guaranteed that the material can be completely and evenly loaded in the compartment. Therefore, material leakage may occur, or the compartment may tilt. The leakage of materials requires secondary cleaning, which generates secondary workload, and the tilting of the compartment will affect the driving control and safety of the vehicle. Therefore, during the loading process, the shovel driver and the mine car driver often adjust the body position to make the docking more accurate, but both vehicles are relatively large and more troublesome to operate. Frequent position adjustment will also affect the loading efficiency. Summary of the invention
[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a mine car loading monitoring device and alignment method to solve the problems in the prior art of uneven material distribution, easy tilting and leakage when the mine car is loading, and inconvenient and inaccurate alignment between the shovel and the mine car.
[0004] The technical solution adopted by the present invention is as follows: The present invention provides a mine car loading monitoring device, including a shovel and a mine car, the shovel is provided with a bucket, the mine car is provided with a carriage, the mine car is provided with an active adjustment mechanism and a monitoring and adjustment mechanism for monitoring and adjusting the loading accuracy and uniformity, and the position layout of the two vehicles during loading is mostly that the mine car is parked horizontally in front of the shovel, that is, the travel directions of the shovel and the mine car are perpendicular to each other; when the material is lowered, from the perspective of the travel direction of the mine car, the uneven material discharge has a greater impact on the left and right directions of the mine car than on the front and rear directions of the mine car, that is, when the material is unevenly discharged, the mine car is more likely to produce unevenness and tilt in the left and right directions, so a monitoring and adjustment mechanism is provided for detecting and adjusting the left and right tilt of the carriage, and an active adjustment mechanism is provided for adjusting the front and rear tilt of the carriage.
[0005] The monitoring and adjusting mechanism includes a layer of base box, a car connecting block, a bottom box connecting platform and an air spring. The layer of base box is a box with an open top, and its length and width are larger than the mine car car. The car is arranged in the layer of base box, and the bottom box connecting platform is fixedly arranged in the layer of base box. The car connecting block is fixedly connected to the bottom of the mine car car, and the car connecting block is slidably connected to the bottom box connecting platform. The air spring is located on both sides of the bottom box connecting platform, connecting the car and the layer of base box. A half worm gear is provided on the bottom box connecting platform, and an empty slot is provided on the car connecting block. An adjusting worm is rotatably provided in the empty slot. The adjusting worm is meshed with the half worm gear, and an adjusting motor is connected to the adjusting worm.
[0006] When the adjusting motor starts, it drives the adjusting worm to rotate. Since the half worm gear is fixed relative to the adjusting worm gear, the adjusting worm gear rotates around the outside of the half worm gear, thereby driving the carriage connecting block to rotate on the bottom box connecting platform, and then driving the carriage to rotate left and right, so as to evenly adjust the material in the carriage.
[0007] The carriage is provided with an inclination sensor, which is connected to the controller and the regulating motor. When the material is unloaded evenly, the carriage will tilt. Then, the inclination of the carriage can be adjusted in time by controlling the monitoring and regulating mechanism, which can make the loading of materials more even and improve the stability of the vehicle during driving.
[0008] Furthermore, since the air spring has adjustability, an air pump is connected to the air spring, and the air pump and the inclination sensor are connected via a controller.
[0009] Furthermore, the bottom box connecting platform is semi-cylindrical, an arc-shaped slide groove is provided on the arc surface of the bottom box connecting platform, the bottom of the carriage connecting block is a concave arc shape, and a slider slidably connected to the arc-shaped slide groove is provided at the bottom of the carriage connecting block, and the semi-worm gear is arranged on the arc surface of the bottom box connecting platform.
[0010] Furthermore, the active adjustment mechanism includes a two-layer base box, a shock absorber and an active balancing component. The two-layer base box is a box with an open top, and its length and width are larger than the one-layer base box. The one-layer base box is arranged in the two-layer base box, and an upper connecting piece is arranged at the bottom of the one-layer base box. A lower connecting piece is arranged in the two-layer base box, and the upper connecting piece and the lower connecting piece are hinged. The active balancing component is arranged on both sides of the two-layer base box and is located between the one-layer base box and the two-layer base box. The shock absorber is arranged between the one-layer base box and the two-layer base box to play a supporting and shock absorbing role. The active balancing component is provided with multiple groups along the front and rear directions of the mine car to improve the adjustment force.
[0011] Furthermore, the active balancing component includes a protective shell, a fixed rack, an extended-range rack, a lifting rack, a movable gear, a fixed gear and a pressure rod, the fixed gear is fixedly arranged in the protective shell, the pressure rod is slidably arranged in the protective shell and passes through the protective shell, the movable gear is arranged on the pressure rod, the movable gear is meshed with the fixed rack, the extended-range rack is slidably arranged in the protective shell, and the extended-range rack is meshed with the movable gear.
[0012] When the pressure rod slides, it drives the movable gear to roll on the fixed rack and on the support rack, and at the same time drives the extended-range rack to slide and increase its stroke. Since the extended-range rack not only slides up and down with the movable gear, but also has a rolling connection between the two, the stroke of the extended-range rack is superimposed with the double stroke brought by sliding and rolling, so that the stroke is doubled.
[0013] The fixed gear is rotatably arranged in the protective shell, the lifting rack is meshed with the fixed gear, the range-increasing rack is meshed with the fixed gear, and the range-increasing rack and the lifting rack are located on both sides of the fixed gear.
[0014] When the range-extending rack slides, it drives the fixed gear to rotate, and then the fixed gear drives the lifting rack to slide. Through the conversion of the fixed gear, the range-extending rack and the lifting rack move in opposite directions.
[0015] Therefore, when the pressure rod is pressed down, it drives the range-extending rack to increase the sliding stroke through the action of the movable gear and the fixed rack, and turns the sliding direction through the fixed gear and transmits it to the lifting rack, which obtains an upward and range-extending force.
[0016] The active balancing component acts on a layer of base box. When the loading in the carriage is uneven and it tilts to one side, the pressure rod slides down under pressure, and the lifting rack is lifted with a larger stroke, pushing the layer of base box to the other side. It not only resists the tilt, but also produces an over-resistance effect, so that the material in the carriage automatically rolls to the other side, automatically controlling the uniformity of the material in the carriage.
[0017] Furthermore, a slideway is provided in the protective shell, the pressure rod is slidably arranged in the slideway, a pressure plate is provided on the pressure rod, and a spring is provided on the lower side of the pressure plate in the slideway to push the pressure rod to maintain contact with a layer of base box.
[0018] Furthermore, the bucket is provided with an alignment laser light, and the angle of the alignment laser light is adjustable.
[0019] Furthermore, in order to improve the supporting shape, the air springs are provided in multiple groups, and the shock absorbers are provided in multiple groups.
[0020] The present invention discloses a method for aligning a mine car load, comprising the following steps:
[0021] S1, control the bucket of the forklift to move to the loading position;
[0022] S2. According to the position of the shovel bucket of the shovel truck, the mine car is controlled to move and adjust the position so that the car body can dock with the bucket;
[0023] S3. Adjust the angle of the laser light so that the irradiated point can be aligned with the mine car, and fix the laser light;
[0024] S4. During loading, the forklift is adjusted to the unloading position. At this time, the alignment laser light is turned on to illuminate the points on the ground. The mine car adjusts its position according to the points to improve the adjustment and alignment efficiency.
[0025] Furthermore, the alignment laser lamps are provided in plurality to increase the number of positioning points, thereby improving the accuracy of alignment.
[0026] Furthermore, the alignment laser lamp is connected to an alignment motor for controlling its angle adjustment. The forklift is provided with an electronic control unit and an information collection module. Different vehicle models require separate adjustment of the alignment laser lamp. The adjustment information of the alignment laser lamps corresponding to different vehicle models that need to be adjusted is input into the electronic control unit for storage. The forklift is provided with control buttons, and the electronic control unit stores the control motor for automatic adjustment. The control buttons control different vehicle models respectively to realize a one-button control function. When loading different vehicle models, it is only necessary to press the corresponding control button to automatically adjust the angle of the alignment laser lamp, so that different vehicle models can be accurately docked with the bucket to achieve efficient loading.
[0027] The beneficial effects achieved by the present invention using the above structure are as follows: This scheme provides a mine car loading monitoring device and alignment method. In view of the problem that uneven materials are prone to occur when the mine car is loaded, which in turn affects the stability of the car body, the active adjustment mechanism and the monitoring and adjustment mechanism are used to realize the functions of active monitoring and automatic adjustment, and the car body is adjusted and controlled from multiple directions. It has the function of overbalancing, so that the originally tilted car body tilts in the opposite direction, and then moves the material in the opposite direction to achieve a uniform distribution effect. At the same time, in view of the current problem of inconvenient alignment of mine cars and shovels, an efficient and fast loading and alignment method is provided. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0041] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.
[0042] The present invention provides a mining vehicle loading monitoring device, comprising a shovel 1 and a mining vehicle 2, wherein the shovel 1 is provided with a bucket 3, the mining vehicle 2 is provided with a carriage 4, and the mining vehicle 2 is provided with an active adjustment mechanism 5 and a monitoring adjustment mechanism 6 for monitoring and adjusting loading accuracy and uniformity. The two vehicles are usually arranged in such a manner that the mining vehicle 2 is horizontally parked in front of the shovel 1, that is, the travel directions of the shovel 1 and the mining vehicle 2 are perpendicular to each other, such as Figure 1 When the material is lowered, from the perspective of the traveling direction of the mine car 2, the uneven material discharge has a greater impact on the left and right directions of the mine car 2 than on the front and rear directions of the mine car 2, that is, when the material is discharged unevenly, the mine car 2 is more likely to be uneven and tilted in the left and right directions. Therefore, in this embodiment, a monitoring and adjustment mechanism 6 is provided for detecting and adjusting the left and right tilt of the carriage 4, and an active adjustment mechanism 5 is provided for adjusting the front and rear tilt of the carriage 4. Figure 2-3 .
[0043] like Figure 4 The monitoring and adjusting mechanism 6 includes a layer of base box 7, a car connecting block 8, a bottom box connecting platform 9 and an air spring 10. The layer of base box 7 is a box with an open top, and its length and width are larger than the car 4 of the mine car 2. The car 4 is arranged in the layer of base box 7. The bottom box connecting platform 9 is fixedly arranged in the layer of base box 7. The car connecting block 8 is fixedly connected to the bottom of the car 4 of the mine car 2. The car connecting block 8 is slidably connected to the bottom box connecting platform 9. The air spring 10 is located on both sides of the bottom box connecting platform 9, connecting the car 4 and the layer of base box 7. Figure 6-8 A half worm gear 11 is provided on the bottom box connecting platform 9, and an empty slot 12 is provided on the carriage connecting block 8. An adjusting worm 13 is rotatably provided in the empty slot 12. The adjusting worm 13 is meshed with the half worm gear 11, and an adjusting motor 14 is connected to the adjusting worm 13.
[0044] When the adjusting motor 14 starts, it drives the adjusting worm 13 to rotate. Since the half worm gear 11 is fixed relative to the adjusting worm 13, the adjusting worm 13 rotates around the outer side of the half worm gear 11, thereby driving the carriage connecting block 8 to rotate on the bottom box connecting platform 9, and then driving the carriage 4 to rotate left and right, so as to adjust the material in the carriage 4 evenly.
[0045] The carriage 4 is provided with an inclination sensor, which is connected to the regulating motor 14 through a controller. When the material is unloaded evenly, the carriage 4 is tilted, and then the inclination of the carriage 4 is adjusted in time by controlling the monitoring and regulating mechanism 6, which can make the loading of materials more uniform and improve the stability of the vehicle during driving.
[0046] Since the air spring 10 is adjustable, an air pump is connected to the air spring 10 , and the air pump and the inclination sensor are connected via a controller.
[0047] The bottom box connecting platform 9 is semi-cylindrical, and an arc-shaped slide groove 15 is provided on the arc surface of the bottom box connecting platform 9. The bottom of the carriage connecting block 8 is a concave arc shape, and a slider slidably connected to the arc-shaped slide groove 15 is provided at the bottom of the carriage connecting block 8. The semi-worm gear 11 is arranged on the arc surface of the bottom box connecting platform 9.
[0048] In order to improve the supporting shape, the air springs 10 are arranged in multiple groups.
[0049] like Figure 5 The active adjustment mechanism 5 includes a two-layer base box 16, a shock absorber 17 and an active balancing assembly 18. The two-layer base box 16 is a box body with an open top, and its length and width are greater than the first-layer base box 7. The first-layer base box 7 is arranged in the two-layer base box 16, and an upper connecting piece 19 is arranged at the bottom of the first-layer base box 7. The second-layer base box 16 is provided with a lower connecting piece 20, and the upper connecting piece 19 and the lower connecting piece 20 are hinged. The active balancing assembly 18 is arranged on both sides of the two-layer base box 16 and is located between the first-layer base box 7 and the second-layer base box 16. The shock absorber 17 is arranged between the first-layer base box 7 and the second-layer base box 16, and plays a supporting and shock-absorbing role. The active balancing assembly 18 is provided with multiple groups along the front and rear directions of the mining car 2 to improve the adjustment force.
[0050] like Fig. 9 The active balancing assembly 18 includes a protective shell 21, a fixed rack 22, an extended-range rack 23, a lifting rack 24, a movable gear 25, a fixed gear 26 and a pressure rod 27. The fixed gear 26 is fixedly arranged in the protective shell 21, the pressure rod 27 is slidably arranged in the protective shell 21 and passes through the protective shell 21, the movable gear 25 is arranged on the pressure rod 27, the movable gear 25 is meshed with the fixed rack 22, the extended-range rack 23 is slidably arranged in the protective shell 21, and the extended-range rack 23 is meshed with the movable gear 25.
[0051] When the pressure rod 27 slides, it drives the movable gear 25 to roll on the fixed rack 22 and on the support rack, and at the same time drives the range-extending rack 23 to slide and increase its stroke. Since the range-extending rack 23 not only slides up and down with the movable gear 25, but also has a rolling connection between the two, the stroke of the range-extending rack 23 is superimposed with the double stroke brought by sliding and rolling, so that the stroke is doubled.
[0052] The fixed gear 26 is rotatably disposed in the protective housing 21 , the lifting rack 24 is meshed with the fixed gear 26 , the range-increasing rack 23 is meshed with the fixed gear 26 , and the range-increasing rack 23 and the lifting rack 24 are located on both sides of the fixed gear 26 .
[0053] When the range-extending rack 23 slides, it drives the fixed gear 26 to rotate, and then the fixed gear 26 drives the lifting rack 24 to slide. Through the conversion of the fixed gear 26, the range-extending rack 23 and the lifting rack 24 move in opposite directions.
[0054] Therefore, when the pressure rod 27 is pressed down, it drives the range-extending rack 23 to increase the sliding stroke through the action of the movable gear 25 and the fixed rack 22, and turns the sliding direction through the fixed gear 26 and transmits it to the lifting rack 24, which obtains an upward and range-extending force.
[0055] The active balancing component 18 acts on a layer of base box 7. When the loading in the carriage 4 is uneven and it tilts to one side, the pressure rod 27 slides down under pressure, and the lifting rack 24 is lifted with a larger stroke, pushing the layer of base box 7 to the other side, which not only resists the tilt but also produces an over-resistance effect, so that the material in the carriage 4 automatically rolls to the other side, and the uniformity of the material in the carriage 4 is automatically controlled.
[0056] A slideway 28 is provided in the protective shell 21 , and the pressure rod 27 is slidably provided in the slideway 28 . A pressure plate 29 is provided on the pressure rod 27 . A spring is provided on the lower side of the pressure plate 29 in the slideway 28 to push the pressure rod 27 to maintain contact with a layer of base box 7 .
[0057] In order to improve the supporting shape, the air springs 10 are provided in multiple groups, and the shock absorbers 17 are provided in multiple groups.
[0058] During specific use, during the loading process, from the perspective of the traveling direction of the mine car 2, when the uneven unloading causes the carriage 4 to tilt in the left and right directions, the inclination sensor detects the tilt and controls the adjusting motor 14 through the controller. The adjusting motor 14 starts to drive the adjusting worm 13 to rotate. Since the half worm gear 11 is fixed relative to the adjusting worm 13, the adjusting worm 13 rotates around the outer side of the half worm gear 11, thereby driving the carriage connecting block 8 to rotate on the bottom box connecting platform 9, adjusting the carriage 4 to be horizontal, or tilted in the opposite direction, so that the material in the carriage 4 is adjusted to be evenly distributed; when the carriage 4 tilts in the front and rear directions, the pressure rod 27 here will be pressed down, and the pressure rod 27 will slide downward, and the movable gear 25 will roll on the fixed rack 22 and on the support rack, while driving the range-extending rack 23 to slide and increase its stroke. At the same time, the lifting rack 24 slides upward and the stroke is also greater than the pressure rod 27, thereby lifting a layer of the base box 7 and tilting it to the other side, causing the material to roll in the opposite direction, thereby producing a balancing and regulating effect.
[0059] In the embodiment, the monitoring and adjusting mechanism 6 is not limited to adjusting the left and right tilt of the car 4, but can also be used for adjustment in the front and rear directions; the active adjusting mechanism 5 is not limited to adjusting the front and rear tilt of the car 4, but can also be used to adjust the tilt in the left and right directions.
[0060] In the embodiment, the detection of the inclination sensor and the control by the controller are not limited to leveling the carriage 4, but can also be used to adjust the inclination in the opposite direction so that the materials slide to the other side.
[0061] In the embodiment, since there are gaps among the carriage 4, the first-layer base box 7, and the second-layer base box 16, protective cloths are provided at the gaps to prevent material particles from entering.
[0062] The bucket 3 is provided with an alignment laser lamp 30 , and the alignment laser lamp 30 is capable of adjusting the angle.
[0063] The present invention discloses a method for aligning a mine car load, comprising the following steps:
[0064] S1, controlling the bucket 3 of the forklift 1 to move to the loading position;
[0065] S2, according to the position of the bucket 3 of the shovel truck 1, control the mine car 2 to move and adjust the position so that the carriage 4 can dock with the bucket 3;
[0066] S3, adjust the angle of the alignment laser lamp 30 so that the irradiated point can be aligned with the mine car 2, and fix the alignment laser lamp 30;
[0067] S4, when loading, the forklift 1 is adjusted to the unloading position, and the alignment laser light 30 is turned on to illuminate the point 31 on the ground, such as Fig.10 , the mine car 2 adjusts its position according to the point 31, so as to improve the adjustment and alignment efficiency.
[0068] The alignment laser lamps 30 are provided in plurality to increase the number of positioning points, thereby improving the alignment accuracy.
[0069] In the embodiment, the pattern irradiated by the alignment laser lamp 30 may be a laser point or a rectangular frame pattern.
[0070] The alignment laser light 30 is connected to an alignment motor for controlling its angle adjustment. An electronic control unit and an information acquisition module are provided in the forklift 1. Different vehicle models require the alignment laser light 30 to be adjusted separately. The adjustment information of the alignment laser light 30 corresponding to different vehicle models that need to be adjusted is input into the electronic control unit for storage. The forklift 1 is provided with a control button, and the electronic control unit stores and controls the motor to automatically adjust. The control button controls different vehicle models respectively to realize a one-button control function. When loading different vehicle models, it is only necessary to press the corresponding control button to automatically adjust the angle of the alignment laser light 30, so that different vehicle models can be automatically and accurately docked with the bucket 3 to achieve an efficient loading effect.
