Description

Technical Field

[0001] The present invention relates to the technical field of glial layer index determination, and more specifically, to a glial layer index determination instrument and a determination method thereof. Background Art

[0002] The gelatinous layer index is an indicator used to characterize the plasticity of bituminous coal. It evaluates the coking performance of coal by measuring the maximum thickness (Y value) and final volume shrinkage (X value) of the gelatinous layer formed during the heating process. The bituminous coal gelatinous layer index is measured using a gelatinous layer index tester.

[0003] That is, under constant pressure conditions, the coal sample loaded into the coal cup is heated unilaterally from the bottom, so that the coal sample forms a series of isothermal layers in the coal cup. As the temperature rises, the coal sample gradually decreases, the colloid first thickens and then gradually thins, and at the same time the semi-coke layer gradually thickens until it is completely solidified into semi-coke. By measuring the maximum thickness and final volume shrinkage of the colloid, the coking performance of the coal can be evaluated. Before adding the coal sample to the coal cup, a thin steel rod with a paper tube sleeve needs to be inserted into the coal cup. After the coal sample in the coal cup is squeezed in the colloid layer index measuring instrument, the staff manually pulls out the thin steel rod to form a hole for measurement, and then uses a probe for measurement.

[0004] However, during the measurement of the colloidal layer index, the staff needs to manually pull the thin steel rod out of the coal cup, which is time-consuming and laborious. If the thin steel rod is tilted due to the shaking of the staff's hands during this process, it may directly interfere with the coal sample structure, causing deformation or displacement, and further affecting the accurate measurement of the maximum thickness Y value of the colloidal layer, thereby seriously affecting the accuracy of the probe measurement and the accuracy of the volume curve. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a colloid layer index measuring instrument and a measuring method thereof.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a colloid layer index measuring instrument, comprising a workbench, a cover installed on the top of the workbench and a control box installed on one side of the cover, an adjustment component is installed inside the workbench, and the adjustment component includes two groups of furnace bricks.

[0007] A clamping assembly is installed inside the workbench, and the clamping assembly includes a bearing mechanism arranged on the top of the two groups of furnace bricks. The two groups of bearing mechanisms each include a coal cup inserted on the top of the corresponding furnace brick and a support plate installed on the top of the coal cup. A pressure rod and a thin steel rod are vertically penetrated through the top of the support plate, and the outer wall of the thin steel rod is sleeved with a paper tube.

[0008] A measuring component is installed on the top of the workbench, and the measuring component includes a connecting frame arranged on the top of the workbench, a driving motor is installed on the side wall of the connecting frame, an output end of the driving motor is connected to a flat plate, and a probe is arranged on one side of the bottom of the flat plate.

[0009] A positioning assembly is installed on the top of the flat plate.

[0010] The present invention is further configured as follows: a gripping assembly is installed at the bottom of the plate and away from the probe, the gripping assembly includes a first ring body and a second ring body rotatably connected to the bottom of the plate, the first ring body and the second ring body are arranged in an upper and lower arrangement, a plurality of groups of telescopic rods are hingedly installed between the first ring body and the second ring body, and a three-jaw chuck is installed at the bottom of the second ring body.

[0011] The grabbing assembly also includes a second motor installed on the top of the flat plate, the output end of the second motor passes through the flat plate and is connected to a first gear, the top of the first ring body is sleeved with a second gear, and the first gear and the second gear are meshed.

[0012] The present invention is further configured as follows: a clamping mechanism is installed at the bottom of the three-jaw chuck, and the clamping mechanism includes three arc-shaped plates, and the three arc-shaped plates are respectively connected to the three clamping jaws of the three-jaw chuck, and the inner wall of each arc-shaped plate is provided with a sliding groove, and the side wall of each arc-shaped plate is slidably connected with a clamping plate, and the clamping plates are slidably connected by sliding blocks and corresponding sliding grooves. The bottom of each clamping plate is conically arranged, and a plurality of limiting strips are connected to the bottom of the inner wall of the clamping plate, and a fixing strip is connected to the inner wall of each arc-shaped plate, and a through hole is formed between the three fixing strips.

[0013] The present invention is further configured as follows: the adjustment component includes a bracket installed inside the workbench and a displacement mechanism installed on the top of the bracket, the two furnace bricks are slidably connected to the top of the displacement mechanism, the clamping component includes four cylinders, each two cylinders form a group, the tops of the cylinders in the same group are connected to a pressure plate, and the middle of the bottom surface of the pressure plate is connected to an extrusion column.

[0014] By adopting the above technical solution, the thrust of the telescopic rod is utilized, and the clamping mechanism moves downward smoothly, so that the splint contacts and slides with the support plate, and then the three-jaw chuck drives the arc plate and the splint to gradually approach, tightly clamping the thin steel rod. When the telescopic rod moves upward, the clamping mechanism rises in a coordinated manner as a whole, and the thin steel rod is pulled out smoothly, while the splint and the limit strip limit the top of the paper tube, thereby realizing electric removal of the thin steel rod and effectively avoiding the problem of thin steel rod shaking that may be caused by manual operation.

[0015] While the thin steel rod is being clamped and pulled out, the second motor starts, driving the first gear to rotate. The rotation of the first gear further drives the second gear, the first ring body, the second ring body, the three-claw chuck and the entire clamping mechanism to rotate synchronously. At this time, the three fixing bars work closely together, driving the thin steel rod to rotate synchronously while being pulled upward. This design effectively alleviates the situation where the paper tube may follow the upward movement of the thin steel rod, ensuring the stability and accuracy of the operation.

[0016] The present invention is further configured as follows: the measuring component includes an electric slide rail installed on the top of the workbench, the top of the electric slide rail is slidably connected to the slide, the top of the slide is installed with a vertical pole, the connecting frame is installed on the outer side wall of the vertical pole, the top of the connecting frame is installed with an adjusting cylinder, the piston rod of the adjusting cylinder passes through the connecting frame and is connected to a connecting plate, and the driving motor is installed on the side wall of the connecting plate.

[0017] The present invention is further configured as follows: a first motor is installed on the top of the flat plate and above the probe, the output end of the first motor passes through the flat plate and is connected to a rotating tube, an L-shaped groove is provided at the bottom of the outer wall of the rotating tube, a connecting tube is inserted into the interior of the rotating tube, a convex column is connected to the outer wall of the connecting tube, the convex column is slidably connected to the inside of the L-shaped groove, and a probe is installed at the bottom of the connecting tube.

[0018] By adopting the above technical scheme, after the coal sample in the coal cup is in a compressed state, the staff will take out the thin steel rod and retain the paper tube. Then the probe is adjusted in position by using the electric slide rail and the adjusting cylinder. The probe moves to the top of the paper tube. Then the coal sample in the coal cup is heated, and the adjusting cylinder pushes the driving motor and the plate downward, causing the first motor to drive the rotating tube, the connecting tube and the probe to move downward. The probe is inserted into the hole at the position of the paper tube to measure the colloid layer of the heated coal sample. At the same time, the first motor drives the rotating tube, the connecting tube and the probe to rotate at a low speed to alleviate the adhesion of the colloid. If the probe is contaminated, the L-shaped groove and the convex column on the connecting tube can be used to quickly disassemble the used probe and replace the unused probe, thereby ensuring the accuracy of the probe measurement.

[0019] The present invention is further configured as follows: the positioning assembly includes a fixing frame installed on the top of the flat plate and a fixing rod vertically installed inside the fixing frame, the outer side wall of the fixing rod is connected to two hinged plates, the ends of the hinged plates are hinged with clamping arms, and a two-way cylinder is horizontally installed on the top of the fixing frame, and the two piston rods of the two-way cylinder are respectively engaged with the ends of the two clamping arms.

[0020] The present invention is further configured as follows: the two clamping arms are both arranged in an arc shape, and clamping blocks are installed on opposite sides of the two clamping arms.

[0021] The present invention is further configured as follows: two top plates are installed on the outer side wall of the fixing rod, and V-shaped blocks are installed on the side of the two top plates away from the fixing rod. Two grooves are symmetrically opened on the side wall of the V-shaped block, and an auxiliary block is installed inside each groove.

[0022] By adopting the above technical solution, after the thin steel rod is pulled out once and before the clamping mechanism is released, the bidirectional cylinder pushes the two clamping arms to swing, so that the two clamping arms and the two clamping blocks cooperate to clamp the thin steel rod to maintain the position and height of the thin steel rod. At the same time, the two V-shaped blocks limit the coaxiality of the thin steel rod to prevent the thin steel rod from deviating and causing deformation of the paper tube.

[0023] A method for measuring a glial layer index, using the glial layer index measuring instrument described above, comprises the following steps: S1. Place the coal sample to be measured into the coal cup, insert a pressure rod and a thin steel rod into the coal cup to be used, and cover the outside of the thin steel rod with a paper tube. Then install the support plate on the top of the coal cup, and then embed the coal cup into the top of the furnace brick for use.

[0024] S2. When measuring the coal sample, the furnace brick moves to the bottom of the clamping assembly, the pressure rod is pressed down and maintained in the squeezed state, and then the thin steel rod is clamped by the grabbing assembly and pulled up a certain distance, then the grabbing assembly releases the thin steel rod, and the positioning assembly clamps the thin steel rod at the same time. After the grabbing assembly readjusts its position, it clamps the thin steel rod again and repeats the last upward pulling action until the thin steel rod is completely pulled out.

[0025] S3. When the thin steel rod is pulled out, the positioning assembly is used to limit the position, height and coaxiality of the thin steel rod.

[0026] S4. When the thin steel rod is completely pulled out, there will be a hole at the position of the paper tube, and then the coal sample in the coal cup will be heated. At the same time, the driving motor drives the plate to rotate 180 degrees, and the probe moves to the top of the paper tube. Then the probe is inserted into the hole at the position of the paper tube to measure the colloid layer of the heated coal sample.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: (1) By setting up a grabbing assembly and utilizing the thrust of the telescopic rod, the clamping mechanism moves downward smoothly, causing the clamping plate to contact and slide with the support plate. Then, the three-jaw chuck drives the arc plate and the clamping plate to gradually approach and tightly clamp the thin steel rod. When the telescopic rod moves upward, the clamping mechanism rises as a whole and smoothly pulls out the thin steel rod. The clamping plate and the limit strip limit the top of the paper tube, thereby realizing the electric removal of the thin steel rod and effectively avoiding the problem of the thin steel rod shaking that may be caused by manual operation.

[0028] (2) While the thin steel rod is being clamped and pulled out, the second motor starts, driving the first gear to rotate. The rotation of the first gear further drives the second gear, the first ring body, the second ring body, the three-claw chuck and the entire clamping mechanism to rotate synchronously. At this time, the three fixing bars work closely together, driving the thin steel rod to rotate synchronously while being pulled upward. This design effectively alleviates the situation where the paper tube may follow the upward movement of the thin steel rod, ensuring the stability and accuracy of the operation.

[0029] (3) After the thin steel rod is pulled out once and before the clamping mechanism is released, the two-way cylinder pushes the two clamping arms to swing, causing the two clamping arms and two clamping blocks to cooperate to clamp the thin steel rod, maintaining the position and height of the thin steel rod. At the same time, the two V-shaped blocks limit the coaxiality of the thin steel rod to prevent the thin steel rod from deviating and causing deformation of the paper tube.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0044] See also Figure 1-Figure 11 , the present invention provides the following technical solutions: Example 1, see Figure 1 and Figure 2 A colloidal layer index measuring instrument comprises a workbench 1, a cover 2 installed on the top of the workbench 1, and a control box 3 installed on one side of the cover 2. The workbench 1 and the cover 2 cooperate to form a colloidal layer index measuring environment. An adjusting component 4 is installed inside the workbench 1. The adjusting component 4 is used to heat and keep warm the coal sample to be measured. The specific structure of the adjusting component 4 is as follows: See also Figure 2 and Figure 3The adjustment component 4 includes two groups of furnace bricks 43. A bracket 41 is installed inside the workbench 1. A displacement mechanism 42 is installed on the top of the bracket 41. The two furnace bricks 43 are slidably connected to the top of the displacement mechanism 42. The displacement mechanism 42 can be an electric conveyor belt mechanism. Two displacement blocks are connected to the conveyor belt of the electric conveyor belt mechanism, and the two furnace bricks 43 are respectively installed on the top of the two displacement blocks. When the conveyor belt of the electric conveyor belt mechanism is driven, the two displacement blocks simultaneously drive the two furnace bricks 43 to move horizontally, thereby adjusting the position of the furnace bricks 43.

[0045] See also Figure 2-Figure 4 A clamping assembly 5 is installed inside the workbench 1. The clamping assembly 5 includes four cylinders 52. Every two cylinders 52 form a group. The tops of the cylinders 52 in the same group are connected to a pressing plate 53. The middle of the bottom surface of the pressing plate 53 is connected to an extrusion column 54.

[0046] A bearing mechanism 51 is provided on the top of the two groups of furnace bricks 43. The two groups of bearing mechanisms 51 include a coal cup 511 inserted into the top of the corresponding furnace brick 43 and a support plate 512 installed on the top of the coal cup 511. A pressure rod 513 and a thin steel rod 514 are vertically penetrated through the top of the support plate 512, and a paper tube is sleeved on the outer wall of the thin steel rod 514.

[0047] The furnace brick 43 is used to place the supporting mechanism 51. The coal cup 511 in the supporting mechanism 51 is suitable for filling the coal sample to be measured, and the pressure rod 513 is suitable for compacting the coal sample. The thin steel rod 514 is used to reserve measurement holes in the compacted coal sample filled in the coal cup 511, and the paper tube prevents the coal sample from collapsing.

[0048] Specifically, a pressure rod 513 and a thin steel rod 514 are inserted into the coal cup 511 to be used, and a paper tube is sleeved on the outside of the thin steel rod 514. Then, the support plate 512 is installed on the top of the coal cup 511, and the coal sample to be measured is placed in the coal cup 511. Then, the coal cup 511 is embedded in the top of the furnace brick 43 for standby use. When the coal sample is measured, the furnace brick 43 moves to the bottom of the squeezing column 54, and the pressure plate 53 and the squeezing column 54 are driven downward by the oil cylinder 52 to press down the pressure rod 513 and maintain the squeezing state, thereby ensuring that the coal sample in the coal cup 511 is in a compressed state.

[0049] See also Figure 2 , Figure 5 and Figure 6 A measuring component 6 is installed on the top of the workbench 1. The measuring component 6 is used to measure the colloid layer index of the coal sample. The specific structure of the measuring component 6 is as follows: See also Figure 2 , Figure 5 and Figure 6The measuring component 6 includes an electric slide rail 61 installed on the top of the workbench 1. The electric slide rail 61 can be a stepper motor linear guide slide seat module, that is, the stepper motor drives the lead screw in the linear guide rail to rotate, causing the slide seat to slide along the extension direction of the lead screw and the linear guide rail. The top of the electric slide rail 61 is slidably connected with a slide table 62, and the slide table 62 is connected to the slide seat of the electric slide rail 61. When the slide seat moves, the slide table 62 moves synchronously. A vertical rod 63 is installed on the top of the slide table 62, and a connecting frame 64 is installed on the outer wall of the vertical rod 63. An adjusting cylinder 65 is installed on the top of the connecting frame 64. The adjusting cylinder 65 The piston rod of the throttling cylinder 65 passes through the connecting frame 64 and is connected to the connecting plate 66. A driving motor 67 is installed on the side wall of the connecting plate 66. The output end of the driving motor 67 is connected to the flat plate 68. A probe 603 is arranged on the bottom side of the flat plate 68. When the slide 62 moves, it drives the connecting frame 64, the adjusting cylinder 65, the connecting plate 66, the driving motor 67 and the flat plate 68 to move synchronously, thereby adjusting the position of the probe 603. The adjusting cylinder 65 is used to push the connecting plate 66 up and down, thereby driving the driving motor 67 and the flat plate 68 to move up and down, thereby adjusting the height of the probe 603.

[0050] In this embodiment, refer to Figure 2 , Figure 5 and Figure 6 A first motor 69 is installed on the top of the plate 68 and above the probe 603. The output end of the first motor 69 passes through the plate 68 and is connected to the rotating tube 601. An L-shaped groove is provided at the bottom of the outer wall of the rotating tube 601. A connecting tube 602 is inserted into the interior of the rotating tube 601. A boss 604 is connected to the outer wall of the connecting tube 602. The boss 604 is slidably connected to the inside of the L-shaped groove. A probe 603 is installed at the bottom of the connecting tube 602. The first motor 69 is used to drive the rotating tube 601 to rotate, and the connecting tube 602 is clamped with the rotating tube 601 through the L-shaped groove and the boss 604, and is locked by screws after clamping. The probe 603 is installed inside the connecting tube 602, and the probe 603 and the connecting tube 602 are quickly disassembled through the boss 604 and the L-shaped groove.

[0051] Specifically, after the coal sample in the coal cup 511 is in a compressed state, the staff will take out the thin steel rod 514 and keep the paper tube. Then the probe 603 will adjust its position by using the electric slide rail 61 and the adjusting cylinder 65. The probe 603 will move to the top of the paper tube. Then the coal sample in the coal cup 511 will be heated, and the adjusting cylinder 65 will push the driving motor 67 and the flat plate 68 downward, causing the first motor 69, the rotating tube 601, the connecting tube 602 and the probe 603 to move downward. The probe 603 will extend into the hole at the position of the paper tube to measure the colloid layer of the heated coal sample. At the same time, the first motor 69 will drive the rotating tube 601, the connecting tube 602 and the probe 603 to rotate at a low speed to alleviate the adhesion of the colloid.

[0052] If the probe 603 is contaminated, the used probe 603 can be quickly disassembled and replaced with an unused probe 603 through the cooperation between the L-shaped groove and the protruding column 604 on the connecting tube 602, thereby ensuring the accuracy of the measurement of the probe 603.

[0053] In the second embodiment, during the measurement of the gelatinous layer index, the staff needs to manually rotate and pull the thin steel rod 514 out of the coal cup 511. If the thin steel rod 514 tilts during this process, it may not only directly interfere with the coal sample structure, causing deformation or displacement, but also affect the accurate measurement of the maximum thickness Y value of the gelatinous layer, thereby seriously affecting the measurement accuracy of the probe 603 and the accuracy of the volume curve.

[0054] To this end, a grab assembly 7 is installed at the bottom of the plate 68 and away from the probe 603. The grab assembly 7 is suitable for linearly pulling out the thin steel stick 514 from the middle of the coal sample. The specific structure of the grab assembly 7 is as follows: See also Figure 6-Figure 9 The grabbing assembly 7 includes a first ring body 74 and a second ring body 75 rotatably connected to the bottom of the flat plate 68. The first ring body 74 and the second ring body 75 are arranged in an upper and lower arrangement. A plurality of telescopic rods 76 are hingedly installed between the first ring body 74 and the second ring body 75. A three-claw chuck 77 is installed at the bottom of the second ring body 75. A clamping mechanism 78 is installed at the bottom of the three-claw chuck 77. The telescopic rod 76 is used to adjust the spacing between the first ring body 74 and the second ring body 75. When the telescopic rod 76 contracts, the second ring body 75 will be pulled closer to the first ring body 74, thereby driving the three-claw chuck 77 and the clamping mechanism 78 to move synchronously. The three-claw chuck 77 and the clamping mechanism 78 cooperate to grab the thin steel rod 514. At the same time, the clamping mechanism 78 can also limit the paper tube sleeved on the outside of the thin steel rod 514. The specific structure of the clamping mechanism 78 is as follows: See also Figure 7-Figure 9The clamping mechanism 78 includes three arc-shaped plates 781, and the three arc-shaped plates 781 are respectively connected to the three clamping claws of the three-claw chuck 77. The inner wall of each arc-shaped plate 781 is provided with a slide groove 783. The side wall of each arc-shaped plate 781 is slidably connected with a clamping plate 784. The clamping plate 784 is slidably connected by a slider and a corresponding slide groove 783. The bottom of each clamping plate 784 is conical, and the bottom of the inner wall of the clamping plate 784 is connected with a plurality of limit strips 785. The limit strips 785 can be made of rubber. When the three arc-shaped plates 781 are respectively When driven by the three jaws of the three-jaw chuck 77, the three arc plates 781 respectively drive the corresponding clamping plates 784 to move synchronously. When the three arc plates 781 are close to each other, they are spliced ​​to form a tube body, and when the three clamping plates 784 are close to each other, they are spliced ​​to form a limiter for limiting the position of the paper tube. The paper tube is in the conical part of the clamping plate 784. A fixing strip 782 is connected to the inner wall of each arc plate 781. Through holes are formed between the three fixing strips 782. When the three fixing strips 782 are close to each other, they are spliced ​​to form a clamp for clamping the thin steel rod 514.

[0055] Specifically, when the coal sample is measured, the displacement mechanism 42 drives the furnace brick 43 to move to the bottom of the extrusion column 54, and drives the pressure plate 53 and the extrusion column 54 to move downward through the oil cylinder 52 to press the pressure rod 513 downward and maintain the extrusion state, and then the telescopic rod 76 pushes the second ring body 75 and the three-claw chuck 77 to move downward. At this time, the bottom of the clamping plate 784 contacts the top of the support plate 512, and slides upward inside the corresponding arc plate 781 under the reaction force, and then the three clamping claws of the three-claw chuck 77 respectively control the three arc plates 781 to approach each other, so that the three clamping plates 784 approach each other, among which the three fixed bars 782 cooperate to clamp the thin steel rod 514, and the clamping plate 784 and the limit bar 785 cooperate to limit the top of the paper tube, thereby realizing the effect of electric removal of the thin steel rod 514.

[0056] Then, the telescopic rod 76 is contracted to move the second ring body 75, the three-claw chuck 77, the arc plate 781 and the fixing bar 782 upward, so that the thin steel rod 514 is pulled up a certain distance. During the process of the thin steel rod 514 being pulled up, the clamping plate 784 and the limit bar 785 continue to maintain the limiting effect on the top of the paper tube under the influence of gravity. After the thin steel rod 514 is pulled to a certain height, the three-claw chuck 77 and the clamping mechanism 78 cooperate to loosen the thin steel rod 514, and the telescopic rod 76 is extended to drive the second ring body 75, the three-claw chuck 77 and the clamping mechanism 78 to move downward to re-clamp the thin steel rod 514, and repeat the last upward pulling action until the thin steel rod 514 is completely pulled out.

[0057] In the third embodiment, when the thin steel rod 514 is pulled out, if the paper tube is improperly pulled due to the pulling force of the coal sample and the thin steel rod 514, the paper tube may be pulled out together or deformed, and only restricting the top of the paper tube may still damage the shape of the paper tube.

[0058] For this purpose, see Figure 6-Figure 9 The grabbing assembly 7 also includes a second motor 71 installed on the top of the flat plate 68. The output end of the second motor 71 passes through the flat plate 68 and is connected to a first gear 72. The top of the first ring body 74 is sleeved with a second gear 73. The first gear 72 and the second gear 73 are meshed. When the thin steel rod 514 is clamped and pulled out, the second motor 71 drives the first gear 72 to rotate, causing the first gear 72 to drive the second gear 73, the first ring body 74, the second ring body 75, the three-claw chuck 77 and the clamping mechanism 78 to rotate synchronously as a whole. The three fixed bars 782 cooperate to drive the thin steel rod 514 to rotate, that is, the thin steel rod 514 rotates synchronously during the process of being pulled upward, thereby alleviating the situation where the paper tube follows the thin steel rod 514 to move upward.

[0059] When the thin steel rod 514 is being pulled out, since it is being pulled out indirectly, the grabbing assembly 7 needs to readjust the grabbing position after the thin steel rod 514 is pulled out for a certain length. During this process, if the thin steel rod 514 is not restricted, the thin steel rod 514 will be affected by gravity to topple over or squeeze the paper tube at the bottom, thereby causing the paper tube to deform.

[0060] See also Figure 6 and Fig.10 For this purpose, a positioning assembly 8 is installed on the top of the flat plate 68 and above the first ring body 74. When the thin steel rod 514 is pulled out, the positioning assembly 8 is used to limit the position, height and coaxiality of the thin steel rod 514. The specific structure of the positioning assembly 8 is as follows: In this embodiment, the positioning assembly 8 includes a fixing frame 81 installed on the top of the flat plate 68 and a fixing rod 82 vertically installed inside the fixing frame 81. The outer wall of the fixing rod 82 is connected to two hinged plates 85. The ends of the hinged plates 85 are hinged with clamping arms 83. The two clamping arms 83 are both arranged in an arc shape, and clamping blocks 86 are installed on the opposite sides of the two clamping arms 83. A two-way cylinder 84 is horizontally installed on the top of the fixing frame 81. The two piston rods of the two-way cylinder 84 are respectively engaged with the ends of the two clamping arms 83. The two-way cylinder 84 is used to push one end of the two clamping arms 83 to move, causing the clamping arms 83 to swing on the corresponding hinged plate 85. The thin steel rod 514 can be initially clamped by the cooperation of the two clamping arms 83, so that the thin steel rod 514 can remain stable during the period of being pulled out and the clamping mechanism 78 readjusting the clamping position.

[0061] See also Fig.10Two top plates 87 are installed on the outer wall of the fixing rod 82, and V-shaped blocks 88 are installed on the side of the two top plates 87 away from the fixing rod 82. Two grooves 89 are symmetrically opened on the side wall of the V-shaped block 88, and an auxiliary block 801 is installed inside each groove 89. When the clamping arm 83 clamps the thin steel rod 514, the two V-shaped blocks 88 are used to limit the coaxiality of the thin steel rod 514.

[0062] Specifically, before the thin steel rod 514 is pulled out once and before the clamping mechanism 78 is released, the two-way cylinder 84 pushes the two clamping arms 83 to swing, so that the two clamping arms 83 and the two clamping blocks 86 cooperate to clamp the thin steel rod 514, keeping the position and height of the thin steel rod 514 unchanged. At the same time, the two V-shaped blocks 88 limit the coaxiality of the thin steel rod 514 to prevent the thin steel rod 514 from deviating and causing deformation of the paper tube.

[0063] After the positioning component 8 clamps the thin steel rod 514, the clamping mechanism 78 can release and readjust the clamping of the thin steel rod 514. When the clamping mechanism 78 pulls the thin steel rod 514 upward, the positioning component 8 cancels the clamping of the thin steel rod 514. Thereafter, before the clamping mechanism 78 releases the thin steel rod 514, the positioning component 8 re-clamps the thin steel rod 514, and repeats this process until the thin steel rod 514 is completely pulled out.

[0064] Since the thin steel rod 514 is relatively long, each time the clamping mechanism 78 pulls the thin steel rod 514, the thin steel rod 514 needs to readjust its coaxiality to ensure that each position of the outer wall of the thin steel rod 514 remains coaxial. The two V-shaped blocks 88 can achieve the effect of maintaining the coaxiality of each position of the outer wall of the thin steel rod 514. While each position of the outer wall of the thin steel rod 514 remains coaxial, it is pulled up and down. Each time the thin steel rod 514 is pulled, the positioning assembly 8 and the clamping mechanism 78 alternately clamp the thin steel rod 514, which not only achieves the purpose of indirectly pulling out the thin steel rod 514, but also ensures that the thin steel rod 514 will not fall.

[0065] When the thin steel rod 514 is completely pulled out, there is a hole at the position of the paper tube, and then the coal sample in the coal cup 511 is heated. At the same time, the driving motor 67 drives the flat plate 68 to rotate 180 degrees, and the probe 603 moves to the top of the paper tube. Then the probe 603 is inserted into the hole at the position of the paper tube to measure the colloid layer of the heated coal sample.

[0066] Embodiment 4, a method for measuring a glial layer index, using a glial layer index measuring instrument as described above, comprises the following steps: S1. Put the coal sample to be measured into the coal cup 511, insert the pressure rod 513 and the thin steel rod 514 into the coal cup 511 to be used, and put a paper tube on the outside of the thin steel rod 514. Then install the support plate 512 on the top of the coal cup 511, and then embed the coal cup 511 into the top of the furnace brick 43 for use.

[0067] S2. When measuring the coal sample, the furnace brick moves to the bottom of the clamping assembly, the pressure rod is pressed down and maintained in the squeezed state, and then the thin steel rod is clamped by the grabbing assembly and pulled up a certain distance, then the grabbing assembly releases the thin steel rod, and the positioning assembly clamps the thin steel rod 514 at the same time, the grabbing assembly readjusts its position and clamps the thin steel rod again, and repeats the last upward pulling action until the thin steel rod is completely pulled out.

[0068] The more specific steps of S2 are: S21. When measuring the coal sample, the displacement mechanism 42 drives the furnace brick 43 to move to the bottom of the extrusion column 54, and drives the pressure plate 53 and the extrusion column 54 to move downward through the oil cylinder 52 to press the pressure rod 513 downward and maintain the extrusion state. Then the telescopic rod 76 pushes the second ring body 75 and the three-claw chuck 77 to move downward. At this time, the bottom of the clamping plate 784 contacts the top of the support plate 512, and slides upward inside the corresponding arc plate 781 under the reaction force. Then, the three clamping claws of the three-claw chuck 77 respectively control the three arc plates 781 to approach each other, so that the three clamping plates 784 approach each other, and the three fixed bars 782 cooperate to clamp the thin steel rod 514, and the clamping plate 784 and the limit bar 785 cooperate to limit the top of the paper tube.

[0069] S22. Then, the telescopic rod 76 is contracted to move the second ring body 75, the three-claw chuck 77, the arc plate 781 and the fixing bar 782 upward, so that the thin steel rod 514 is pulled upward by a certain stroke. During the process of the thin steel rod 514 being pulled upward, the clamping plate 784 and the limit bar 785 continue to maintain the limiting effect on the top of the paper tube under the influence of gravity. At the same time, the second motor 71 drives the first gear 72 to rotate, so that the first gear 72 drives the second gear 73, the first ring body 74, the second ring body 75, the three-claw chuck 77 and the clamping mechanism 78 to rotate synchronously as a whole. The three fixing bars 782 cooperate to drive the thin steel rod 514 to rotate, that is, the thin steel rod 514 rotates synchronously during the process of being pulled upward, thereby alleviating the situation where the paper tube follows the thin steel rod 514 to move upward.

[0070] S23, then the three-jaw chuck 77 and the clamping mechanism 78 cooperate to loosen the thin steel rod 514, the telescopic rod 76 extends to drive the second ring body 75, the three-jaw chuck 77 and the clamping mechanism 78 to move downward to re-clamp the thin steel rod 514, and repeat the last upward pulling action until the thin steel rod 514 is completely pulled out.

[0071] S3. When the thin steel rod 514 is being pulled out, the positioning assembly 8 is used to limit the position, height and coaxiality of the thin steel rod 514.

[0072] The more specific steps of S3 are: S31. After the thin steel rod 514 is pulled out once and before the clamping mechanism 78 is released, the bidirectional cylinder 84 pushes the two clamping arms 83 to swing, so that the two clamping arms 83 and the two clamping blocks 86 cooperate to clamp the thin steel rod 514, maintaining the position and height of the thin steel rod 514. At the same time, the two V-shaped blocks 88 limit the coaxiality of the thin steel rod 514.

[0073] S32. After the positioning component 8 clamps the thin steel rod 514, the clamping mechanism 78 can release and readjust the clamping of the thin steel rod 514. When the clamping mechanism 78 pulls the thin steel rod 514 upward, the positioning component 8 cancels the clamping of the thin steel rod 514. Thereafter, before the clamping mechanism 78 releases the thin steel rod 514, the positioning component 8 re-clamps the thin steel rod 514, and repeats this process until the thin steel rod 514 is completely pulled out.

[0074] S4. When the thin steel rod 514 is completely pulled out, there is a hole at the position of the paper tube, and then the coal sample in the coal cup 511 is heated. At the same time, the driving motor 67 drives the flat plate 68 to rotate 180 degrees, and the probe 603 moves to the top of the paper tube. Then the probe 603 extends into the hole at the position of the paper tube to measure the colloid layer of the heated coal sample.

[0075] The more specific steps of S4 are: S41. When the thin steel rod 514 is completely pulled out, there is a hole at the position of the paper tube. Then the coal sample in the coal cup 511 is heated. At the same time, the driving motor 67 drives the flat plate 68 to rotate 180 degrees, and then the electric slide rail 61 is used to drive the slide 62 to move, and the probe 603 moves to the top of the paper tube. Then the cylinder 65 is adjusted to push the driving motor 67 and the flat plate 68 downward, causing the first motor 69 to drive the rotating tube 601, the connecting tube 602 and the probe 603 to move downward. The probe 603 extends into the hole at the position of the paper tube to measure the colloid layer of the heated coal sample. At the same time, the first motor 69 drives the rotating tube 601, the connecting tube 602 and the probe 603 to rotate at a low speed to alleviate the adhesion of the colloid.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
