Description

Technical Field

[0001] The present application relates to the technical field of coal sampling and detection, and in particular to a movable coal sampling and detection device. Background Art

[0002] Coal sample refers to a representative part of coal taken in accordance with regulations to determine certain characteristics of coal.

[0003] Coal samples need to be tested after they are collected. Traditional collection and testing are usually performed separately. Among them, the collection equipment includes large and small vehicles, lifting spiral sampling heads, primary feeders, crushers, reducers, sample boxes, residual coal processing devices, etc., which are large in structure, scattered in location, and occupy a large area; the testing equipment is set up in other areas. Since the samples need to be processed after the test, residual coal processing devices are also required, resulting in equipment redundancy and increased costs; and, especially for sampling equipment, since there are more coal ash and charcoal slag in the sampling environment, special dust-proof designs are required for the power, control and other components of each device, further increasing the cost; at the same time, the collection and testing environment usually includes carriages (trains or trucks, etc.) and coal piles. Traditional collection and testing devices are usually fixed and cannot be used flexibly in a variety of testing environments; more importantly, the sample collection equipment is scattered and the testing equipment is located in different areas, and the sample transfer time is long, which can easily lead to moisture loss in the sample, and then lead to inaccurate moisture test results.

[0068] An embodiment of the present application provides a movable coal sampling and testing device, including a mobile device 100 and a compartment 200 disposed on the mobile device 100 .

[0069] Preferably, the mobile device 100 is a vehicle body, which includes a cab frame assembly and a main frame arranged behind the cab frame assembly. A vehicle power mechanism is arranged below the cab of the cab frame assembly, and a compartment 200 is arranged above the main frame, thereby facilitating the overall balanced setting of the device and improving the stability and safety of movement.

[0070] The body 200 includes a bottom plate, and a mutually isolated first zone 210 and a second zone 220 are arranged above the bottom plate along the width direction of the body 200, so that the first zone 210 and the second zone 220 are respectively located on both sides of the mobile device 100, which is convenient for moving to a designated position for operation, and the first zone 210 and the second zone 220 have a longer space, so that it is convenient to arrange multiple devices side by side in sequence, and thus convenient for maintenance.

[0071] Preferably, the first zone 210 is provided with a control zone 221 and a power zone 222 which are isolated from each other along the length direction of the compartment 200 .

[0072] The control area 221 is provided with a plurality of control units, such as a power distribution cabinet 201 , a PLC control cabinet 202 , a robot control cabinet 203 , and a quality inspection control cabinet 204 , etc. The power area 222 is provided with a generator set 205 and a robot power system 206 .

[0073] The second zone 220 is provided with a robotic arm 300, and a primary sample preparation system 400 and a detection device 500 which are arranged along the length direction of the compartment 200 and on both sides of the robotic arm 300, so that sampling by the robotic arm 300 and coordinated operation of the robotic arm 300 and the primary sample preparation system 400, as well as the robotic arm 300 and the detection device 500 can be realized in a limited space, and the weight distribution of the second zone 220 is more reasonable, thereby improving the movement stability and safety of the device.

[0074] At the same time, this method reduces the area occupied by coal sampling and testing by integrating the robotic arm 300, the primary sample preparation system 400, the detection equipment 500 and the related control unit and power system in the same compartment 200, and greatly shortens the time from sampling to sample testing, thereby improving the sampling and testing efficiency and the accuracy of sample moisture testing. Through partitioned and isolated installation, the independent dustproof performance requirements for each device are reduced, thereby reducing costs, and multiple devices can be shared, further reducing costs. By loading and moving the mobile device 100, it can be freely moved in a variety of testing environments, improving the flexibility of sampling and testing.

[0075] It is understandable that a sampling arm 310 may be provided at the end of the mechanical arm 300, and the mechanical arm 300 is used to drive the sampling arm 310 to extend into the coal for sampling, and the sampling arm 310 may be of different types according to needs. The primary sample preparation system 400 is used to receive the sample sampled by the mechanical arm 300 and prepare the sample. The detection device 500 is used to receive the sample and detect it.

[0076] The multiple control units of the control area 221 are connected to the corresponding devices to realize control, for example, the robot arm control cabinet 203 is connected to the robot arm 300, and the quality inspection control cabinet 204 is connected to the detection equipment 500. In particular, independent control units are set for the robot arm 300 and the detection equipment 500, which is convenient for procurement, thereby controlling costs, and then the overall automatic control of the device is realized by connecting to the PLC control cabinet 202.

[0077] The generator set 205 of the power area 222 is used for power supply and can usually be connected to the power distribution cabinet 201 of the control area 221. The robot arm power system 206 is connected to the robot arm 300 and is used to realize the movement of the robot arm 300. Preferably, the robot arm power system 206 is an air compression system.

[0078] It should be noted that the first zone 210 is usually equipped with power equipment and control equipment, such as a generator set 205, a robotic arm power system 206, and various control units. The appearance of each device is relatively regular, and the integration and compactness are relatively high; the second zone 220 is usually equipped with sampling and detection equipment, such as a robotic arm 300, a sample preparation system, a detection equipment 500, etc. The appearance of each device is different, and the robotic arm 300 requires a certain amount of space for movement; and the weight of the generator set 205 is much greater than that of other devices.

[0079] Therefore, in one embodiment, the width of the first zone 210 is smaller than the width of the second zone 220, that is, the area of ​​the first zone 210 is smaller than the area of ​​the second zone 220, which is convenient for the installation of various devices; and the area of ​​the second zone 220 is larger, providing a larger activity space for the robot arm 300, which is convenient for the operation of the robot arm 300; at the same time, when the center of gravity of the first zone 210 and the second zone 220 are both at their centers, the force arm of the first zone 210 is smaller than the force arm of the second zone 220, and the weight of the first zone 210 is much greater than the weight of the second zone 220, thereby facilitating the balance of the left and right sides of the compartment 200 and improving the stability and safety of the movement of the device.

[0080] In one embodiment, the generator set 205 and the robotic arm 300 are correspondingly arranged in the width direction of the car body 200, so as to balance the weight of the first area 210 and the second area 220, that is, to improve the left-right balance of the car body 200, thereby improving the movement stability and safety of the device.

[0081] In one embodiment, a sample collection box 700 is provided below the bottom plate corresponding to the primary sample preparation system 400 , and the sample collection box 700 is connected to the primary sample preparation system 400 to realize sample collection.

[0082] In one embodiment, a waste material collection box 800 is provided under the bottom plate corresponding to the detection device 500, and the waste material collection box 800 is used to realize real-time collection of waste materials to avoid direct discharge of waste materials, polluting the environment, or even mixing into the area to be sampled, affecting the detection accuracy.

[0083] In a specific embodiment, in order to realize real-time collection of waste materials, the waste material collection box 800 is connected to the primary sample preparation system 400 .

[0084] In another specific embodiment, the detection device 500 also needs waste materials, and the waste material collection box 800 is also connected to the detection device 500. For example, the waste material collection box 800 is connected to the primary sample preparation system 400 through a transmission device 810, such as a conveyor belt, and the entrance of the waste material collection box 800 is placed below the waste material opening of the detection device 500. The transmission device 810 transmits the waste materials generated by the primary sample preparation system 400 to the waste material collection box 800, and the detection device 500 directly discharges the waste samples after detection into the waste material collection box 800, that is, the movable coal sampling and detection device also includes a waste material recovery device, and the waste material recovery device includes a waste material collection box 800 and a transmission device 810.

[0085] In one embodiment, a transmission device 810 is provided along the length direction of the compartment 200 and corresponding to the waste material collection box 800 to transmit the waste samples of the primary sample preparation to the waste material collection box 800 .

[0086] In one embodiment, an energy storage device 110 is provided along the width direction of the car body 200 and corresponding to the waste material collection box 800, which is beneficial to the weight balance in the width direction of the car body and ensures the stability of the car body 200 during operation.

[0087] Specifically, when the mobile device 100 is a vehicle body, the energy storage device 110 is a fuel tank for a fuel vehicle and a battery pack for an electric vehicle, and both are usually heavy. Coal sample preparation usually adopts a crushing and shrinking method, which results in a large amount of waste material, and thus the weight of the waste material collection box 800 is also large. By arranging the waste material collection box 800 and the energy storage device 110 in correspondence in the width direction of the vehicle body 200, the left and right balance of the vehicle body 200 is improved, thereby improving the stability and safety of the movement of the device.

[0088] In one embodiment, the mobile device 100 includes two rear wheels 120 symmetrically arranged along the width direction of the vehicle body 200 .

[0089] In one embodiment, the generator set 205 and the mechanical arm 300 are respectively located above the two rear wheels 120, that is, the generator set 205 and the mechanical arm 300 with the heaviest weight in the body 200 are respectively located above the two rear wheels 120, thereby improving the movement stability and safety of the device.

[0090] In one embodiment, the sample collection box 700 and the waste material collection box 800 are respectively located on both sides of the corresponding rear wheel 120, which is convenient for installation, improves the balance of the device, and further improves the movement stability and safety of the device.

[0091] In one embodiment, the compartment 200 includes two side panels arranged along its length direction and a first partition plate arranged on the bottom plate. The two side panels and the first partition plate separate the compartment 200 into a first area 210 and a second area 220. The structure is simple and easy to assemble. It is also convenient to hinge the first L-shaped cover plate 207 and the second L-shaped cover plate 208 with the top of the first partition plate.

[0092] The top of the first partition is rotatably connected with the first L-shaped cover plate 207 and the second L-shaped cover plate 208, and the first L-shaped cover plate 207 is used to cover the first area 210, and the second L-shaped cover plate 208 is used to cover the second area 220, so that when the first L-shaped cover plate 207 and the second L-shaped cover plate 208 are opened, the front of the first area 210 and the second area 220 can be unobstructed, and the top space of the first area 210 and the second area 220 can be greatly expanded, thereby facilitating operation and maintenance.

[0093] In one embodiment, the primary sample preparation system 400 includes a crusher 420 and a reducer 430 to improve the representativeness of the coal sample. The reducer 430 is arranged below the crusher 420, and the inlet of the reducer 430 is connected to the outlet of the crusher 420. The crusher 420 is used to crush the sample, and the reducer 430 is used to reduce the crushed sample.

[0094] Usually, coal particles are of different sizes and uneven mass distribution, which is not conducive to detection and needs to be crushed to a specified particle size.

[0095] Preferably, the shrinking machine 430 used in the present device shrinks the materials while receiving them, so that the volume of the shrinking machine 430 can be controlled so that it can be arranged in the compartment 200 and the shrinking efficiency can be improved.

[0096] Preferably, the power mechanism of the crusher 420 is arranged outside the crusher 420 and is connected to the crushing mechanism inside the crusher 420 through a transmission mechanism.

[0097] In one embodiment, the reduction machine 430 is provided with two outlets, one of which is connected to the waste material collection box 800 to discard the reduction waste, and the other is connected to the sample collection box 700 to collect the reduction samples. For example, the two outlets of the reduction machine 430 are respectively provided with discharge guide cylinders, one discharge guide cylinder is directed toward the transmission device 810 of the waste material collection box 800, and the other discharge guide cylinder is directed toward the sample collection box 700.

[0098] In one embodiment, the primary sample preparation system 400 further includes a material blocking cover 410. The material blocking cover 410 is disposed on the crusher 420 and is used to guide the sample sampled by the sampling arm 310 into the crusher 420, ensuring that all the sample sample falls into the crusher 420, thereby improving the detection accuracy. At the same time, the material blocking cover 410 can also be used to guide the sample when it is output by the sampling arm 310 to fall into the second area 220, thereby contaminating the second area 220, and especially the uncrushed coal is relatively large, and if it is stuck in other components, it is easy to cause jamming, resulting in damage to the equipment.

[0099] In one embodiment, the sampling arm 310 includes a barrel 311 and a sampling mechanism disposed in the barrel 311. The barrel 311 is provided with a plurality of windows 312 connected to the outside along its height direction, and the plurality of windows 312 may be covered with a closing plate to control the sampling volume, that is, by controlling the opening and closing of windows 312 at different heights, the sample can flow out from the corresponding window 312 when the sampling arm 310 is sampling, thereby controlling the sampling volume, and the operation is convenient and reliable.

[0100] It should be noted that, in this method, since the sample is flush with the open window 312, it is easy for the sample to fall from the window 312 to the outside when the sample is output. For example, the sampling mechanism usually includes a screw elevator, which rotates forward to realize the sample ascending sampling, and reverses to realize the sample descending output. The vibration generated at the moment of output start-up is easy to cause the sample to fall from the open window 312 to the outside. Therefore, in order to prevent the sample from falling to the outside when it is output, affecting the detection accuracy and polluting the environment, etc., in this embodiment, the sampling arm 310 with the window 312 especially needs to cooperate with the material blocking cover 410.

[0101] In a specific embodiment, the material blocking cover 410 includes a material blocking portion 411 and a flow guiding portion 412 . The flow guiding portion 412 is located at the end of the material blocking portion 411 and is funnel-shaped.

[0102] The material blocking portion 411 is vertically arranged, with both ends connected in the height direction and a semi-enclosed structure in the circumferential direction. The robotic arm 300 can drive the sampling arm 310 to embed into the material blocking portion 411, and make the window 312 of the sampling arm 310 blocked by the inner wall of the material blocking portion 411, thereby preventing the sample from falling from the window 312 into the second zone 220 when the sampling arm 310 outputs the sample.

[0103] In one embodiment, a rotary conveyor 710 is provided in the sample collection box 700, and a plurality of carrying plates are provided on the rotary conveyor 710, and the carrying plates are used to carry sample barrels 720, and the plurality of sample barrels 720 are moved one by one to the sample collection box 700 and connected to the primary sample preparation system 400 under the drive of the rotary conveyor 710. The rotary conveyor 710 may be a conveyor chain, and the sample barrels 720 may be detachably connected to the carrying plates to improve their stability in moving with the rotary conveyor 710. Typically, eight sample barrels 720 may be provided.

[0104] In one embodiment, the second zone 220 is also provided with a secondary sample preparation system 600, which is used to mix and prepare multiple samples prepared by the primary sample preparation system 400 to further improve the uniformity of the samples, that is, to improve the representativeness of the coal samples, thereby improving the detection accuracy, and the prepared samples are transported to the detection equipment 500 for detection.

[0105] In one embodiment, the secondary sample preparation system 600 is arranged side by side with the detection device 500 and is located at an end away from the robotic arm 300, which improves the compactness of the structure and facilitates the operation of the robotic arm 300.

[0106] In one embodiment, the secondary sample preparation system 600 is connected to the waste material collection box 800 to recover the waste materials in real time.

[0107] In one embodiment, the detection device 500 is a visual coal quality detector, such as an X-ray fluorescence coal quality detector.

[0108] In one embodiment, the secondary sample preparation system 600 includes a reduction table 610, a conveyor belt and a paving mechanism. The reduction table 610 is used for secondary sample preparation. The paving mechanism is used to flatten the sample on the conveyor belt so that the thickness of the sample is uniform at each position, thereby improving the accuracy of subsequent detection. The paving mechanism can adopt a paving claw or any flattenable structure. The conveyor belt passes through the outlet of the reduction table 610, the paving mechanism, the detection port of the detection device 500 and the waste material collection box 800 in sequence along its conveying direction, so that the sample can be flattened, detected, and finally discarded while being transported, thereby realizing continuous detection of different samples, and making the secondary sample preparation system 600, the detection device 500 and the waste material collection box 800 compactly integrated, and the space utilization is reasonable.

[0109] In one embodiment, the second zone 220 is also provided with a password packaging table 620, which is arranged on the side of the reduction table 610 close to the detection equipment 500, and a closable sample barrel 720 is arranged on the password packaging table 620. The closable sample barrel 720 is used to store part of the samples in the reduction table 610 to retain the samples.

[0110] In a specific embodiment, the closable sample barrel 720 includes the sample barrel 720 and a cover 630 for covering the sample barrel 720 , and the closure is achieved by covering the sample barrel 720 with the cover 630 .

[0111] It can be understood that when it is necessary to retain samples, first take out some of the evenly mixed samples in the reduction table 610 and then test them. Preferably, all the remaining samples are tested to improve the representativeness of the coal samples and improve the accuracy of the test. At the same time, the same conveyor belt can be used to complete the test and discard the materials, which is beneficial to control the volume of the device and facilitate integration in a compartment 200.

[0112] See also Figure 4-5 , Figure 4 Schematic diagram of the structure of the waste material recovery device and the sample collection box 700 in the embodiment of the present application; Figure 5 It is a partially enlarged structural schematic diagram of the waste material recovery device in the embodiment of the present application.

[0113] In one embodiment, the waste collection box 800 has a first inlet and a second inlet, the first inlet is connected to the primary sample preparation system 400 , and the second inlet is connected to the secondary sample preparation system 600 .

[0114] Preferably, the first inlet is in the shape of an elongated strip and extends along the transmission direction of the transmission device 810 of the waste material recovery apparatus, thereby providing a larger waste material space for the transmission device 810, so that the transmission device 810 can complete the complete waste material process during the transmission process.

[0115] Preferably, the second inlet is located at a position of the waste material collection box 800 away from the outlet of the reduction table 610, so as to facilitate the setting of the conveyor belt of the secondary sample preparation system 600. At the same time, the transmission equipment 810 of the waste material recovery device and the conveyor belt of the secondary sample preparation system 600 can also be arranged in parallel above the waste material collection box 800, thereby improving space utilization.

[0116] In one embodiment, the transmission device 810 of the waste material recovery apparatus includes a limiting frame 811 and a transmission line group disposed in the limiting frame 811 .

[0117] The bottom of the limiting frame 811 has a closing portion and an exit portion. The closing portion is used to prevent the coal in the limiting frame 811 from falling. The exit portion is in the shape of a long strip and is arranged corresponding to the first entrance.

[0118] The transmission line group transmits along the length direction of the waste material collection box 800, and the bottom is hollowed out and covers the first entrance. The transmission line group is connected to a driving member and is driven by the driving member to reciprocate, so that the coal gradually falls from the outlet to the first entrance under the drive of the transmission line group. Therefore, when the transmission line group keeps the working state unchanged, the coal can be gradually accumulated at various positions of the waste material collection box 800 along the transmission direction, thereby improving the space utilization rate of the waste material collection box 800, reducing the dumping frequency of the waste material collection box 800, and thus improving the convenience of use, improving the actual use effect, and at the same time, the transmission line group is simple to control.

[0119] During use, the coal is first accumulated at the front end of the first entrance. As the amount of coal increases to be basically flush with the bottom of the transmission line group, the coal transported subsequently cannot fall at this position, but falls as the transmission line group moves to a farther distance, thereby achieving distributed accumulation at various positions of the waste collection box 800, thereby improving the space utilization rate of the waste collection box 800.

[0120] In one embodiment, the transmission line group includes a transmission chain 812 and a plurality of push plates 813 arranged at intervals on the sides of the transmission chain 812, the transmission chain 812 is connected to the driving member, the plurality of push plates 813 are adapted to the limit frame 811 and form a plurality of push spaces, the plurality of push spaces move under the drive of the transmission chain 812, and push the coal to the first entrance. The transmission chain 812 is preferably a roller chain.

[0121] It should be noted that the coal is in granular form and is easily jammed due to squeezing when being pushed forward through the transmission line assembly, causing it to be unable to fall immediately.

[0122] This method forms a larger pushing space through the push plate 813 and the limit frame 811, which can reduce the risk of coal getting stuck in the transportation line group during transportation and improve transportation reliability; and the longer discarding route formed by the longer first entrance and the longer exit can make the stuck coal pile loosen and fall due to vibration during the movement of the transmission equipment 810, so as to achieve complete discarding; even if it is stuck and cannot be removed, only the independent unit of the transmission chain 812 and the push plate 813 at the corresponding position can be disassembled and replaced, which reduces maintenance costs.

[0123] Please see again Figure 1 , and see Figure 8-9 , Figure 8 This is a schematic diagram of the structure of the first actuator 320 in the embodiment of the present application; Fig. 9 Schematic diagram of the structure of the second actuator 330 in the embodiment of the present application.

[0124] In one embodiment, the robot arm 300 is a six-axis robot arm 300, which improves the degree of freedom of operation and enables more operations.

[0125] In one embodiment, the sampling arm 310 or the first actuator 320 or the second actuator 330 may be replaceably provided at the end of the robot arm 300, so that different operations can be realized through different actuators.

[0126] The robot arm 300 extends into the coal to take samples through the sampling arm 310 .

[0127] The robot arm 300 transfers the sample barrel 720 between the sample collection box 700 and the reduction table 610 through the first actuator 320, and transfers the sample in the sample barrel 720 to the reduction table 610, and the robot arm 300 closes the closable sample barrel 720 through the first actuator 320. For example, the first actuator 320 includes a clamp 331 for grabbing the sample barrel 720, and a suction cup 322 for taking the cover 630 of the sample barrel 720. The suction cup 322 can be set on the arm of the clamp 331, or any position that can take into account the operation of the clamp 331 and the operation of the suction cup 322.

[0128] The robot arm 300 extends into the reduction platform 610 through the second actuator 330 and stirs and mixes the sample in the reduction platform 610, and grabs part of the sample and puts it into the closable sample barrel 720. For example, the second actuator 330 includes a stirring member for stirring the sample and a grabbing member for grabbing the sample.

[0129] In a specific embodiment, the stirring member of the second actuator 330 is a stirring plate 331, and the stirring member is driven by the mechanical arm to stir. The grasping member includes a receiving tube 332, a push-pull rod 333, and a transmission connecting rod group 334. The push-pull rod 333 drives the receiving tube 332 away from or close to the stirring plate 331 through the transmission connecting rod group 334 to realize the opening and closing of the receiving tube 332 to receive and seal the sample, and is driven by the mechanical arm to move to the top of the sample barrel 720 on the password packaging table 620.

[0130] Please see again Figure 1-2 In one embodiment, the second zone 220 is further provided with a rack 900 , and the rack 900 is used to accommodate the sampling arm 310 , the first actuator 320 and the second actuator 330 .

[0131] Preferably, the rack 900 is arranged side by side with the primary sample preparation system 400 and is located at an end away from the robotic arm 300, so as to avoid affecting the routine operation of the robotic arm 300 and thus ensure the sampling and testing efficiency.

[0132] Preferably, the rack 900 is provided with a plurality of vertical accommodating spaces, and a card interface 910 for clamping the sampling arm 310 or the first actuator 320 or the second actuator 330 is provided at the top of the vertical accommodating space, so as to facilitate the storage of the sampling arm 310, the first actuator 320 and the second actuator 330 in a vertical state in the rack 900, and the sampling arm 310, the first actuator 320 and the second actuator 330 in a vertical state are convenient for the robot arm 300 to perform automated installation or disassembly.

[0133] Since the rack 900 is arranged in the second zone 220 and directly faces the sampling zone, coal is easy to fall from above to the inside of the sampling arm 310, the first actuator 320 and the second actuator 330 in the rack 900, causing damage or affecting the detection accuracy. Therefore, the top of the card interface 910 is further covered with a removable top cover.

[0134] In one embodiment, the second zone 220 is further provided with horizontal gratings and vertical gratings. For example, vertical gratings are provided along the side panel edge of the compartment 200 close to the front end of the mobile device 100 , and horizontal gratings are provided along the bottom panel edge of the compartment 200 .

[0135] The horizontal grating is used to obtain the length of the sampled carriage, and the vertical grating is used to obtain the height of the sampling pile and the height of the sampled carriage and chassis, so that the sampling environment characteristics can be obtained, which makes it easier to calculate the sampling points and improve the representativeness of the sampling.

[0136] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
