Description

Technical Field

[0001] The present invention belongs to the field of measuring devices, and more specifically, relates to an automated testing device for bleeding rate of controllable low-strength materials. Background Art

[0002] Currently, the measurement of bleeding rate of materials usually adopts two measurement methods: volume method and mass method.

[0003] For the measurement of bleeding rate by volume method, timing starts from when the material is mixed with water and left to stand. The freshly mixed material is loaded into a container and left to stand for a period of time to allow water to secrete. Starting from the time of standing, the bleeding water is sucked out multiple times with a pipette. Then, the bleeding volume is determined by measuring the volume of the secreted water in the container, and the bleeding rate is determined by calculating the ratio of the volume of the secreted water to the volume of the original water in the material.

[0004] For the measurement of bleeding rate by mass method, the freshly mixed material (such as concrete mixture) is loaded into a specific container and left to stand for a period of time. Then, tools such as a pipette are used to collect the water secreted on the surface, and the mass of the secreted water is determined by weighing. The bleeding rate is determined by calculating the ratio of the mass of the secreted water to the mass of the original water in the material.

[0005] Currently, most of the devices for measuring bleeding of materials perform multiple steps manually, and the influence of environmental temperature changes on the experimental results is relatively large. The measured values have large errors, and the results are greatly affected by the subjective factors of the operators.

[0006] Therefore, a new design that can reduce the measurement errors caused by environmental factors and human factors and can continuously and automatically measure the bleeding rate is needed. Summary of the Invention

Specific embodiments

[0024] The present invention will be further described below in conjunction with specific embodiments.

[0025] As Figure 1 and Figure 2 shown, the present invention mainly includes a base, a suspension member, a lifting member, a conveying member, and a feeding member. A support plate 501 is provided on one side of the base, and a feeding member is provided on the support plate 501. The top surface of the base and the top surface of the support plate 501 are jointly provided with a conveying member. A suspension member and a lifting member are respectively provided above the base on both sides of the conveying member. The entire testing device is uniformly controlled by a control center 104 provided inside the base, so as to realize the automation of bleeding rate detection.

[0026] In this embodiment, the control center 104 is controlled by a single-chip microcomputer. The single-chip microcomputer collects the data of each electronic device for processing, and then controls the relay to drive the electronic device to act through the single-chip microcomputer. Components such as the single-chip microcomputer and the relay are integrated inside the base. The types and models of the single-chip microcomputer and each electronic device are not limited, as long as they can realize the functions required by this solution.

[0027] Four leveling devices 103 are provided at the bottom of the base, respectively located at the four top corner positions of the base. The leveling device 103 is specifically a foot pad that can be adjusted in height by screw rotation. Its specific structure is relatively common, so it will not be elaborated here.

[0028] As Figure 1 and Figure 3 shown, the suspension member is provided above the base. The suspension member mainly includes a support rod 201 and a mounting seat 202. The mounting seat 202 is provided at the top end of the support rod 201 and extends above the lifting member.

[0029] A spirit level 210 is provided above the mounting seat 202. When installing the testing device, the base is leveled through the cooperation of the spirit level 210 and the leveling device 103.

[0030] A temperature sensor 203, a heat dissipation member 204, and a heating tube 209 are provided on the side surface of the support rod 201. A liftable water absorption member 205 and a distance measuring member 206 are provided on the lower surface of the mounting seat 202. The lifting member is mainly used to carry the specimen cylinder 601. The positions where the water absorption member 205 and the distance measuring member 206 are provided are directly above the position where the lifting member carries the specimen cylinder 601.

[0031] The mounting seat 202 and the support rod 201 are hollow structures that are interconnected. The circuits of each component can be connected from the inside of the support rod 201 and the mounting seat 202 to the control center 104 inside the base.

[0032] As Figure 4As shown in the figure, the water absorption component 205 includes an electric push rod 2051 and a micro water pump 2054. The electric push rod 2051 is arranged on the lower surface of the mounting seat 202, and the telescopic end of the electric push rod 2051 is arranged downward. The telescopic end of the electric push rod 2051 is fixedly connected with a hollow tube 2052. A pressure sensor probe 2053 is arranged at the end of the hollow tube 2052. A micro water pump 2054 is arranged on the side of the pressure sensor probe 2053. A water delivery hose 207 is connected to the side of the micro water pump 2054. A water tank 208 is arranged on the base. The other end of the water delivery hose 207 is connected to the water tank 208. Two sets of water absorption components 205 are provided. The movement direction of the driving end of the electric push rod 2051 in one set of water absorption components 205 is perpendicular to the mounting seat 202, and the movement direction of the driving end of the electric push rod 2051 in the other set of water absorption components 205 forms a certain angle with the mounting seat 202.

[0033] When absorbing water, the control center 104 drives the electric push rod 2051 to adjust the height of the hollow tube 2052, so that the hollow tube 2052 moves towards the test cylinder 601. The pressure sensor at the end of the hollow tube 2052 is used to judge whether it touches the surface of the material to be tested. When the pressure reaches a certain level, it means that it has touched the surface of the material to be tested. At this time, an instruction is issued through the control center 104 to stop the movement of the electric push rod 2051 and start the micro water pump 2054 to pump water.

[0034] As Figure 5 shown in the figure, the heat dissipation component 204 mainly includes a packaging box 2041. The packaging box 2041 is arranged on the side of the support rod 201. One side of the packaging box 2041 facing the lifting component is an open structure. A plurality of heat dissipation holes are arranged on the side of the packaging box 2041 away from the lifting component. A hollow vertical rod 2042 is arranged inside the packaging box 2041. A fan motor 2043 is arranged on the hollow vertical rod 2042. A fan blade 2044 is arranged at the output end of the fan motor 2043. The fan motor 2043 is electrically connected to the control center 104. The temperature sensor 203 is located above the heat dissipation component 204, and the heating tube 209 is located below the heat dissipation component 204.

[0035] The control center 104 can correspondingly control the opening and closing of the heat dissipation component 204 and the heating tube 209 according to the real-time temperature detected by the temperature sensor 203. When the temperature is too high, the heat dissipation component 204 is started for ventilation and cooling. When the temperature is too low, the heating tube 209 is started to heat the surrounding environment, so that the detection environment can be maintained at a more appropriate level and the influence of the environmental temperature on the bleeding rate detection can be reduced.

[0036] In this embodiment, the distance measuring component 206 adopts a laser distance sensor to measure the distance between the material inside the sample cylinder 601 and the mounting base 202 by laser, and combines the various dimension data of the sample cylinder 601 set in advance to calculate the actual volume of the material.

[0037] As Figures 6 to 9 shown, the lifting component mainly includes a lifting base 301 and a tabletop 3016. Two ear plates 3011 are symmetrically arranged on the upper surface of the lifting base 301. Two lifting slide rails 3012 are arranged on the upper surface of the lifting base 301 beside the two ear plates 3011. A set of scissors arms 3013 is jointly connected by the ear plate 3011 and the lifting slide rail 3012 on the same side. The tabletop 3016 is arranged at the top of the scissors arms 3013. Ear plates 3011 and lifting slide rails 3012 are also arranged on the lower surface of the tabletop 3016. The ear plates 3011 and lifting slide rails 3012 arranged on the lower surface of the tabletop 3016 correspond to the ear plates 3011 and lifting slide rails 3012 arranged on the upper surface of the lifting base 301. That is to say, directly above the ear plate 3011 arranged on the lifting base 301 is the ear plate 3011 arranged on the lower surface of the tabletop 3016, and directly above the lifting slide rail 3012 arranged on the lifting base 301 is the lifting slide rail 3012 arranged on the lower surface of the tabletop 3016. Two sets of scissors arms 3013 are symmetrically arranged. Each set of scissors arms 3013 includes two intersecting support arms. The intersecting part of the two support arms is rotatably connected. The bottom of one support arm is rotatably connected to the ear plate 3011 on the upper surface of the lifting base 301, and the top is slidably connected to the lifting slide rail 3012 on the lower surface of the tabletop 3016. The bottom of the other support arm is slidably connected to the lifting slide rail 3012 on the upper surface of the lifting base 301, and the top is rotatably connected to the ear plate 3011 on the lower surface of the tabletop 3016. A connecting seat 3018 is arranged at the connection between the scissors arm 3013 and the lifting slide rail 3012. The connecting seat 3018 is rotatably connected to the scissors arm 3013 and slidably connected to the lifting slide rail 3012. The scissors arm 3013 is rotatably connected to the ear plate 3011 and the connecting seat 3018 through a pin shaft 3015. Both ends of the pin shaft 3015 are fixed on the ear plate 3011 or the connecting seat 3018. The scissors arm 3013 is sleeved on the pin shaft 3015 and can rotate around the pin shaft 3015.

[0038] An elevating platform motor 3014 is arranged on the upper surface of the base between the two sets of scissors arms 3013. A sliding seat 3019 is arranged between the two connecting seats 3018 at the bottom of the two sets of scissors arms 3013, and the three are fixedly connected through a pin shaft 3015. The drive shaft of the elevating platform motor 3014 is connected with a threaded rod. The threaded rod passes through the sliding seat 3019 and is threadedly connected to the sliding seat 3019. The elevating platform motor 3014 can drive the sliding seat 3019 to move horizontally.

[0039] The lifting base 301, the scissor arm 3013 and the tabletop 3016 form the structure of a scissor arm lift. By the rotation of the drive shaft of the lift table motor 3014, the slide 3019 threadedly connected to the drive shaft is driven to move, thereby driving the connecting seat 3018 to slide on the lifting slide rail 3012, and further driving the other connection points of the scissor arm 3013 with the lifting base 301 and the tabletop 3016 to move together, controlling the raising and lowering of the tabletop 3016.

[0040] An electronic scale 303 is placed on the upper surface of the tabletop 3016. A plurality of stop blocks 3017 are arranged on the upper surface of the tabletop 3016. The space enclosed by the plurality of stop blocks 3017 arranged on the upper surface of the tabletop 3016 limits the electronic scale 303. Through holes are provided in the area of the tabletop 3016 for placing the electronic scale 303, and a screw lift motor 302 is arranged on the upper surface of the lifting base 301 at a position corresponding to the through holes.

[0041] Four trays 3032 are arranged above the electronic scale 303. The trays 3032 are used to place and fix the sample cylinder 601.

[0042] As Figure 9 and Figure 10 shown, the top of the sample cylinder 601 is provided with a cylinder cover 605 that can be opened and closed by rotation. A piston 602 that fits the inner side wall of the sample cylinder 601 is arranged inside the sample cylinder 601. A push rod 603 is arranged at the bottom of the piston 602. The push rod 603 passes through the bottom of the sample cylinder 601. By pushing the piston 602 through the push rod 603, the sample can be pushed out of the sample cylinder 601 after the sample detection is completed, facilitating the staff to clean the sample cylinder 601. A bottom support 604 is arranged at the bottom of the sample cylinder 601. The bottom support 604 is placed in the space enclosed by the four trays 3032, enabling the sample cylinder 601 to be better fixed on the trays 3032.

[0043] As Figure 1 and Figure 8 shown, the overall structure of the tray 3032 includes four vertical rods perpendicular to the upper surface of the electronic scale 303 and clamping blocks arranged at the tops of the vertical rods. The clamping blocks arranged on the four vertical rods jointly form a shape matching the bottom support 604 of the sample cylinder 601. When the bottom support 604 of the sample cylinder 601 is placed on the tray 3032, the clamping structure of the tray 3032 of the electronic scale 303 can firmly limit the bottom support 604 at the bottom of the sample cylinder 601, preventing it from shaking on the electronic scale 303. Moreover, the vertical rods of the tray 3032 are not connected to each other, and the push rod 603 at the bottom of the sample cylinder 601 can pass between the two vertical rods, and the push rod 603 will not collide with the electronic scale 303 during the transportation of the sample cylinder 601.

[0044] As Figure 11 and Figure 12As shown, the bottom of the electronic scale 303 is the electronic scale base 3031. The electronic scale base 3031 is placed in the area enclosed by the stop blocks 3017 on the tabletop 3016. A stepping motor 3033 is arranged inside the electronic scale base 3031. The driving end of the stepping motor 3033 is connected to a long shaft. The long shaft passes through the upper surface of the electronic scale 303. A through hole is provided on the cylinder cover 605 corresponding to the position of the long shaft. After passing through the upper surface of the electronic scale 303, the long shaft can be embedded into the through hole of the cylinder cover 605. When the sample cylinder 601 is placed on the electronic scale 303, the driving end of the stepping motor 3033 and the cylinder cover 605 are mutually engaged, and the cylinder cover 605 can be driven to rotate by the stepping motor 3033.

[0045] A bevel block 3034 is arranged at the part of the electronic scale base 3031 corresponding to the through hole on the tabletop 3016. The bevel block 3034 is fixedly arranged on the electronic scale base 3031 in an inclined shape. A chute is opened in the bevel block 3034. A slider 3035 is slidably connected in the chute. A positioning groove 3036 is arranged at the bottom of the slider 3035.

[0046] As Figure 13 shown, the output end of the screw lift motor 302 is threadedly connected to a threaded nested rod 3021. A hollow cylinder 3022 is fixedly connected to the screw lift motor 302. The threaded nested rod 3021 is located inside the hollow cylinder 3022. A guide groove is opened on the inner side of the hollow cylinder 3022. A guide block is arranged on the outer side of the threaded nested rod 3021. The guide block is slidably arranged inside the guide groove. A top rod 3023 is arranged at the top of the threaded nested rod 3021. The position of the top rod 3023 corresponds to the positioning groove 3036 at the bottom of the slider 3035.

[0047] Through the design of the guide groove and the guide block, the threaded nested rod 3021 can be moved inside the hollow cylinder 3022 along the direction of the guide groove. The top rod 3023 on the threaded nested rod 3021 jacks up the slider 3035 arranged on the electronic scale base 3031. The slider 3035 moves obliquely upward along the chute, and finally the electronic scale base 3031 is tilted, and then the sample cylinder 601 is tilted, cooperating with two water absorption components 205 with different tilt angles to make the water absorption more thorough.

[0048] As Figure 1 and Figure 14As shown in the figure, a conveying component is jointly installed on the base and the support plate 501. The conveying component mainly includes a conveying bracket 401. At one end of the base, the conveying bracket 401 is provided with a conveying motor 402. The driving shaft of the conveying motor 402 is arranged towards the side of the lifting component. At one end of the support plate 501, the conveying bracket 401 is provided with a rotating shaft 403. The position of the rotating shaft 403 matches that of the driving shaft. A belt pulley and a conveyor belt 404 are arranged between the driving shaft and the rotating shaft 403. A tape buckle 405 is arranged on the conveyor belt 404. A slide rail 406 is arranged at the top of the conveying bracket 401. A conveying plate 407 is fixedly arranged on the tape buckle 405. A through hole for placing the sample cylinder 601 is formed on the side of the conveying plate 407 facing the lifting component. A positioning block 408 matching the sample cylinder 601 is arranged on the upper surface of the conveying plate 407 near the through hole. The side of the conveying plate 407 away from the lifting component is slidably connected to the slide rail 406.

[0049] The conveying component is mainly used to convey the sample cylinder 601, so that the sample cylinder 601 moves back and forth above the base and the support plate 501 for feeding. In order to ensure the levelness between the support plate 501 and the base, a column foot 502 is arranged below the support plate 501. A column foot leveling device 503 is arranged at the bottom of the column foot 502. The structure of the column foot leveling device 503 is the same as that of the leveling device 103. The support plate 501 is leveled through the column foot leveling device 503, so that the support plate 501 and the base are in the same plane.

[0050] As Figure 15 shown in the figure, the feeding component is arranged above the support plate 501. The feeding component includes a support seat 504 fixedly arranged above the support plate 501. A feeding funnel 505 is installed at the top of the support seat 504. When the sample cylinder 601 is moved by the conveying component below the feeding funnel 505 of the support plate 501, feeding can be carried out into the sample cylinder 601 through the feeding funnel 505.

[0051] As Figure 2 shown in the figure, the control center 104 is arranged inside the base, and several relays are also arranged inside the base. The control center 104 is electrically connected to the relays, and then through the relays, it is electrically connected to the electric push rod 2051, the micro water pump 2054, the lifting table motor 3014, the screw lifting motor 302, and the electric control equipment in other components to uniformly control the electric control components in other components. Each sensor is directly connected to the control center 104, such as the pressure sensor probe 2053, the temperature sensor 203, and the ranging component 206. The control center 104 directly processes the collected data.

[0052] As Figure 1As shown in the figure, a display screen 101 and multiple control buttons 102 are also provided on the periphery of the base. The display screen 101 can intuitively show the temperature, as well as the mass and volume of the material to be measured. Through the control buttons 102, manual intervention in the operation of the entire device can be carried out, such as starting, stopping, and resetting, enabling the staff to promptly handle emergencies that occur during the normal operation of the device, such as excessive lifting of the lifting component or the conveying component not reaching the designated position.

[0053] To better understand the working states of the various components of this device during operation, the specific usage process of this embodiment is as follows. However, it should be noted that the time, angle, and other factors used in this usage process are only for reference to demonstrate the usage process and do not constitute a limitation to this solution: Before the experiment starts, first level the equipment by using the leveling device 103 under the base and the column foot leveling device 503 under the support plate 501 in cooperation with the spirit level 210. Then turn on the device, start the control center 104, and press the reset start button on the base to initialize the entire device. At this time, the hollow tube 2052 rises to the highest position to prevent the hollow tube 2052 from colliding with the sample cylinder 601.

[0054] The staff first installs the sample cylinder 601 on the transfer plate 407, and moves the sample cylinder 601 to directly above the electronic scale 303 through the conveying component, so that the bottom support 604 of the sample cylinder 601 matches the position of the tray 3032 of the electronic scale 303. Subsequently, the lifting component rises, the tray 3032 of the electronic scale fits with the bottom support 604 of the sample cylinder 601, and the sample cylinder 601 is lifted from the transfer plate 407. At the same time, the driving end of the stepping motor 3033 is docked with the cylinder cover 605 of the sample cylinder 601. The stepping motor 3033 rotates to rotate and open the cylinder cover 605 of the sample cylinder 601. After the cylinder cover 605 is opened, the lifting component descends, and the sample cylinder 601 falls back onto the transfer plate 407 again, and is moved to below the feeding funnel 505 provided on the support plate 501 by driving the transfer plate 407 of the conveying component. The slurry to be measured is added to the sample cylinder 601 through the feeding funnel 505. Thus, the work of system initialization and feeding is completed.

[0055] After the feeding is completed, the conveying component brings the sample cylinder 601 to directly above the electronic scale 303 again. The lifting component rises again, and the stepping motor 3033 rotates and closes the cylinder cover 605 of the sample cylinder 601. Let the sample cylinder 601 stand for a period of time until water seeps out.

[0056] The timing starts from the time when it is left to stand still. During the first 30 minutes, the control center 104 sends a signal to the stepper motor 3033 and the water absorbing component 205 every 15 minutes to rotate and open the cylinder cover 605 of the sample cylinder 601, and control the electric push rod 2051 of the water absorbing component 205 perpendicular to the mounting seat 202 to extend, driving the micro water pump 2054 to move downward. When the pressure sensor probe 2053 detects a certain resistance (the resistance is greater than the buoyancy of water), the pressure sensor probe 2053 transmits this signal to the control center 104, and then the control center 104 controls the electric push rod 2051 to stop moving, and controls the micro water pump 2054 to start working. The micro water pump 2054 is turned off after 10S. During this period, the water sucked out by the micro water pump 2054 flows to the water tank 208 through the hose.

[0057] After 30 minutes, the tilting water absorption operation is performed every 30 minutes. When tilting water absorption, the control center 104 controls the spiral lifting motor 302 on the lifting component to rotate, and the internal internal threaded rod rotates to make the threaded nested rod 3021 rise in the direction of the guide groove inside the hollow cylinder 3022, and the positioning groove 3036 below the slider 3035 is supported by the upward movement of the push rod 3023. Under the action of the push rod 3023, the slider 3035 inside the slide groove moves obliquely upward along the slide groove, pushing one end of the electronic scale base 3031 to tilt at a certain angle. When it rises to the top, the model tube 601 tilts 20 degrees.

[0058] At this time, the control center 104 controls the electric push rod 2051 of the water absorbing component 205 which is at a certain angle to the mounting seat 202 to descend to perform water absorbing operation. The working principle of the water absorbing process is consistent with the water absorbing component 205 arranged perpendicular to the mounting seat 202.

[0059] When the tilting water absorption is completed, the control center 104 sends a signal to make the electric push rod 2051 rise, and at the same time controls the spiral lifting motor 302 to reverse, so that the sample tube 601 returns to the horizontal. After each water absorption is completed, the control center 104 controls the laser distance sensor to measure the distance of the water-exuding material. The laser distance sensor transmits the acquired signal to the control center 104, and after conversion, the material volume and mass are output to the LCD screen 101.

[0060] During each water absorption operation, the control center 104 first controls the stepper motor 3033 to open the lid 605 of the specimen cylinder 601 for water absorption and measurement. After the water absorption and measurement are completed, the control center 104 controls the stepper motor 3033 to reverse and close the lid 605 of the specimen cylinder 601. At the same time, after each distance measurement, the high-precision special electronic scale 303 above the lifting component measures the mass of the bleeding material in real time. In the previous preparation step, when the specimen cylinder 601 moves above the electronic scale 303, the lifting component works through the lifting table motor 3014 to make the tabletop 3016 rise smoothly. During the rising process of the high-precision special electronic scale 303 installed on the tabletop 3016, the tray 3032 of the electronic scale 303 buckles the bottom support 604 below the specimen cylinder 601, so that the specimen cylinder 601 is separated from the support of the transfer plate 407. At this time, the electronic scale 303 continuously measures the mass of the material in the specimen cylinder in real time and displays it on the base liquid crystal display screen 101.

[0061] A plurality of control buttons 102 are installed on the side of the base. The electric push rod 2051 can be controlled manually by pressing the buttons to perform water absorption lifting, control the spiral lifting motor 302 to work, and control the stepper motor 3033 to work, ensuring that during the operation of the entire device, the staff can intervene manually to handle various emergencies that occur during the operation of the device in a timely manner. Under normal working conditions, no additional control is performed through the control buttons 102.

[0062] When the measurement of the entire process is completed, the specimen cylinder 601 is sent to an easily removable position in the middle of the transfer device through the transfer device. At this time, the specimen cylinder 601 is removed, and the piston 602 inside the specimen cylinder 601 is pushed by the push rod 603 below the specimen cylinder 601 to more conveniently remove all the waste materials, and then the specimen cylinder 601 is cleaned to avoid contamination.

[0063] In terms of environmental variables, the current ambient temperature is detected in real time by the temperature sensor 203 and displayed on the display screen 101 of the base. The specific height of the heat dissipation component 204 is the same as the height when the specimen cylinder 601 is placed on the electronic scale 303. If the current ambient temperature is lower than the set temperature range, the control center 104 turns on the heating tube 209; if the current ambient temperature is higher than the set temperature range value, the control center 104 turns on the heat dissipation device until it reaches the set temperature range, and then the control center 104 sends a signal to turn off the heat dissipation component 204 and the heating tube 209.
