Description

Technical Field

[0001] The present invention relates to the technical field of cement compression testing, and in particular to a cement pressure testing system and method. Background Art

[0002] Cement is a powdery, hydraulic inorganic gelling material that forms a slurry when mixed with water. It can harden in air or water and can firmly bond materials such as sand and stone together. The strength of cement is an important indicator for evaluating cement quality and is the basis for classifying cement strength grades. The compressive strength of cement refers to the ability of a hardened cement mortar specimen to withstand external damage and is one of the important physical and mechanical properties of cement.

[0003] The existing cement pressure testing system cannot realize continuous automatic testing of cement blocks. Manual intervention is required during the test, which increases the workload of staff and reduces work efficiency. Summary of the Invention

[0004] The present application discloses a pressure testing system and method for cement, in order to solve the problem in the prior art that continuous automatic testing of cement blocks cannot be achieved.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions: A pressure testing system for cement, comprising: A turntable is provided with a plurality of through holes along its circumference, and the through holes are provided with an openable and closable discharge plate. The turntable can rotate along its circumference so that the plurality of through holes pass through the first station, the second station, the third station and the fourth station in sequence; A pressing mechanism is provided corresponding to the through hole located at the third station, and is used to perform extrusion and pressure testing on the cement block in the through hole; The linkage mechanism connects the pressing mechanism and multiple unloading plates. When the pressing mechanism moves toward the through hole, the linkage mechanism drives the unloading plate at the fourth station to open so that the cement fragments can be unloaded through the through hole. When the pressing mechanism moves away from the through hole, the linkage mechanism drives the unloading plate at the fourth station to close.

[0006] The test method based on the above-mentioned cement pressure test system includes the following steps: S1. Loading: Located at the first station, in the initial state, the unloading plate is in the closed state, and the cement block is placed on the unloading plate by the robotic arm, and the cement block is supported by the unloading plate; S2, code scanning and identification: Located at the second station, the cement block in S1 is moved to the bottom of the scanner by rotating the turntable. The scanner recognizes the identification code attached to the cement block and reads the information of the cement block; S3, extrusion test: Located at the third station, the cement block whose information was read in S2 is moved to the bottom of the pressing mechanism by rotating the turntable, and the cement block is squeezed and pressure tested by the pressing mechanism; S4, unloading: Located at the fourth station, the cement blocks after the pressure test in S3 are moved to the fourth station by rotating the turntable. When the pressing mechanism moves toward the through hole, the linkage mechanism drives the unloading plate at the fourth station to open, so that the cement blocks can be unloaded through the through hole. When the pressing mechanism moves away from the through hole, the linkage mechanism drives the unloading plate at the fourth station to close.

[0007] The technical solution adopted by the present invention can achieve the following beneficial effects: The present invention realizes the switching of cement blocks among four stations through a turntable. When the pressing mechanism moves toward the cement block, the pressing mechanism drives the unloading plate at the fourth station to open through the linkage mechanism, so that the cement fragments are unloaded through the through hole. When the pressing mechanism moves away from the cement block, the pressing mechanism drives the unloading plate at the fourth station to close through the linkage mechanism, thereby realizing the linkage between the pressing mechanism action and the unloading plate at the fourth station, ensuring "unloading when pressing down and closing when rising". The present invention can realize the full process automation of cement blocks from loading, code scanning and identification, extrusion testing to unloading, improve detection efficiency and data traceability, and do not require manual intervention, thereby reducing the workload of staff and improving work efficiency.

DETAILED DESCRIPTION

[0011] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0012] The terms "first", "second", "third", "fourth", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", "third", "fourth", etc. are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0013] The inventive concept of this application is described here: During actual use, the inventor found that, since the existing cement pressure testing system usually uses a robotic arm to place the solidified cement block into the pressure testing machine when performing a pressure test on the cement block, and then uses a hydraulic device to squeeze the cement block downward and perform a pressure test on it, after the test is completed, the broken blocks are manually cleaned up, and only after the cleaning is completed can the next cement block be placed for testing, thus completing a single test of the cement block. This increases the workload of the staff, reduces work efficiency, and makes it impossible to achieve continuous automated testing of the cement blocks. Moreover, when the cement block is squeezed, the broken blocks are easily scattered. The scattered broken blocks are not only inconvenient to collect and clean, but also pose certain safety hazards to the staff themselves.

[0014] Based on this, the inventor provides a cement pressure testing system and method to solve the above problems.

[0015] The following is combined with Figures 1 to 12 , a cement pressure testing system and method provided in this application are described in detail through specific embodiments and application scenarios.

An L-shaped bracket 30 is installed at one end of the top of the base 20. The bracket 30 is divided into a horizontal portion and a vertical portion. The top end of the base 20 is connected to the vertical portion of the bracket 30, and the upper portion of the vertical portion of the bracket 30 is connected to the horizontal portion of the bracket 30. The pressing mechanism 300 is connected to the horizontal portion of the bracket 30, and the linkage mechanism 400 is connected to the vertical portion of the bracket 30.

Its specific structure and working principle are well known and therefore will not be described in detail here. The motor 50 can be covered with a housing (not shown) to protect the motor 50. A horizontally arranged turntable 100 is mounted on the output shaft of the motor 50. A control panel 70 is installed on one side of the base 20 (adjacent to the side wall of the base 20 where the mounting plate 40 is installed) for controlling the electronic control equipment of the entire pressure test system.

[0017] Reference Figure 3 and Figure 4 A plurality of through holes 110 are formed on the turntable 100 along its circumference. The through holes 110 are provided with a discharge plate 200 that can be opened and closed. The turntable 100 can rotate along its circumference so that the plurality of through holes 110 pass through the first station, the second station, the third station and the fourth station in sequence. Specifically, the turntable 100 is arranged in a circular shape and can rotate around the central axis. The turntable 100 is driven to rotate by the motor 50 to realize the switching of cement blocks between the four workstations; the number of through holes 110 can be 4, 8 or 12. Preferably, the number of through holes 110 is 4, and the through holes 110 are evenly distributed on the circumference of the turntable 100. The through holes 110 pass through the top and bottom surfaces of the turntable 100; the unloading plate 200 is horizontally slidably arranged in the through holes 110; the unloading plate 200 is used to support cement blocks or unload cement fragments.

[0018] At the first station, the cement blocks are placed on the discharge plate 200 by a robotic arm. Specifically, the specific structure and working principle of the robotic arm are common knowledge, so they will not be described in detail here. Those skilled in the art can use commercially available robotic arms for assembly. At the second station, a scanner 10 for identifying the identification code attached to the cement block is provided just above the through hole 110. The information of the cement block is read by the scanner 10. The scanner 10 is mounted on a support plate, which is connected to one side of the horizontal portion of the bracket 30. The specific structure and working principle of the scanner 10 are common knowledge, so they will not be described in detail here. The scanner 10 can be configured as a commercially available product. Of course, those skilled in the art can also make routine improvements based on existing products. At the fourth station, a collection box 60 is provided just below the through hole 110, and the cement fragments are collected by the collection box 60.

[0019] Reference Figure 1 、 Figure 3 and Figure 4 The pressing mechanism 300 is provided corresponding to the through hole 110 located at the third station, and the pressing mechanism 300 is used to perform extrusion and pressure testing on the cement block in the through hole 110; Specifically, the pressing mechanism 300 is located directly above the through hole 110 of the third workstation, and the cement block with read information is rotated directly below the pressing mechanism 300 through the turntable 100; combined with the scanned code information, the pressure test parameters of the pressing mechanism 300 (such as the loading rate of cement blocks of different strength grades) are automatically matched; the base 20 and the bracket 30 are also located at the third workstation.

[0020] Reference Figure 1 、 Figure 3 and Figure 4 The linkage mechanism 400 connects the pressing mechanism 300 and multiple unloading plates 200. When the pressing mechanism 300 moves toward the through hole 110, the linkage mechanism 400 drives the unloading plate 200 located at the fourth station to open, so that the cement fragments can be unloaded through the through hole 110. When the pressing mechanism 300 moves away from the through hole 110, the linkage mechanism 400 drives the unloading plate 200 located at the fourth station to close.

[0021] Specifically, when the pressing mechanism 300 descends to extrude and pressure test the cement blocks, the pressing mechanism 300 drives the unloading plate 200 located at the fourth station to open the through hole 110 through the linkage mechanism 400 to unload the cement fragments. When the pressing mechanism 300 rises, the pressing mechanism 300 drives the unloading plate 200 located at the fourth station to close the through hole 110 through the linkage mechanism 400. The linkage mechanism 400 realizes the linkage between the action of the pressing mechanism 300 and the unloading plate 200 at the fourth station, ensuring "unloading when pressing down and closing when rising".

[0022] Reference Figure 3 and Figure 6 In this embodiment, the pressing mechanism 300 includes a pressing assembly 310, a protective cover 320, a fixing assembly 330 and a connecting rod assembly 340; The linkage mechanism 400 is connected to the movable end of the pressing assembly 310, which is used to squeeze and pressure test the cement block; Specifically, refer to Figure 6 and Figure 7 The downward pressing assembly 310 includes a first telescopic member 311 and a pressing plate 312. The first telescopic member 311 is vertically installed at the top of the horizontal part of the bracket 30. The first telescopic member 311 is a cylinder, a hydraulic cylinder or an electric cylinder. Preferably, the first telescopic member 311 is a hydraulic cylinder; the telescopic rod of the first telescopic member 311 passes through the horizontal part of the bracket 30 and extends to the bottom of the horizontal part of the bracket 30, and a horizontally arranged pressing plate 312 is installed at the bottom of the telescopic rod of the first telescopic member 311. The telescopic rod of the first telescopic member 311 slides with the horizontal part of the bracket 30; a pressure sensor (not shown in the figure) is arranged inside the pressing plate 312; in this embodiment, the movable end of the downward pressing assembly 310 refers to the telescopic rod of the first telescopic member 311 and the pressing plate 312; the linkage mechanism 400 is connected to the telescopic rod of the first telescopic member 311; the pressing plate 312 is driven to rise and fall by the first telescopic member 311 to extrude and pressure test the cement block.

[0023] Reference Figure 3 and Figure 6 The protective cover 320 is slidably connected to the movable end of the pressing assembly 310. The movable end of the pressing assembly 310 extends into the protective cover 320. The protective cover 320 is used to prevent cement blocks from splashing around during extrusion, which not only reduces the risk of workers being injured by splashing objects, but also reduces damage to the equipment caused by the impact of fragments, thereby extending the service life of the equipment. When the cam 320 is in the unlock state, the top of the cam 320 is in the unlock state, and the cam 320 is unlocked, so that the cam 320 can be unlocked.

[0024] Reference Figure 4 and Figure 5In this embodiment, the through hole 110 includes a placement groove 111, a storage groove 112, a movable groove 113 and a bottom groove 114 from top to bottom. The length and width of the storage groove 112 are smaller than the length and width of the placement groove 111, the length and width of the movable groove 113 are larger than the length and width of the storage groove 112, and the length and width of the bottom groove 114 are larger than the length and width of the storage groove 112, so that the cement fragments will not be blocked during the falling process, and the length and width of the bottom groove 114 are smaller than the length and width of the movable groove 113, so as to prevent the unloading plate 200 from moving out of the movable groove 113; the inner size of the protective cover 320 matches the length and width of the storage groove 112, and the outer size of the protective cover 320 matches the length and width of the placement groove 111, so that the lower part of the protective cover 320 can be just completely placed in the placement groove 111, and the lower part of the protective cover 320 is adjusted by the placement groove 111. The movable groove 113 is provided with a stripping plate 200 for sliding, and the cement block is placed in the storage groove 112, and the cement block contacts the top surface of the stripping plate 200. The length direction of the movable groove 113 is the radial direction of the turntable 100. The stripping plate 200 slides in the movable groove 113, which can connect the storage groove 112 with the bottom groove 114 to unload the cement blocks, or disconnect the storage groove 112 from the bottom groove 114, that is, close the through hole 110. Preferably, a brush (not shown) can be provided on the side wall of the storage groove 112 away from the edge of the turntable 100. The brush contacts the surface of the stripping plate 200. When the stripping plate 200 slides to connect the storage groove 112 with the bottom groove 114, the cement blocks on the stripping plate 200 can be cleaned, so that all the cement blocks fall into the collection box 60.

[0025] Reference Figure 3 and Figure 6 The two sides of the lower part of the protective cover 320 are slidably connected with fixing components 330, which are used to squeeze and fix the side walls of the cement block to prevent the cement block from shaking during squeezing, avoid uneven pressure distribution caused by shaking, and make the test data more stable and reliable; Specifically, there are at least two fixing components 330, which are located on both sides of the lower part of the protective cover 320; in this embodiment, there are four fixing components 330, and every two are located on both sides of the lower part of the protective cover 320, so as to improve the fixing efficiency; after the cement block is clamped by the fixing component 330, the impact force of the cement block at the moment of crushing is reduced.

[0026] Reference Figure 6 and Figure 7The connecting rod assembly 340 is connected to the movable end of the pressing assembly 310 located in the protective cover 320, and the fixing assembly 330 is movably connected to the connecting rod assembly 340. When the movable end of the pressing assembly 310 descends, the fixing assembly 330 is driven by the connecting rod assembly 340 to squeeze and fix the side wall of the cement block. When the movable end of the pressing assembly 310 rises, the fixing assembly 330 is driven by the connecting rod assembly 340 to loosen the cement block.

[0027] Specifically, the connecting rod assembly 340 is connected to the top of the pressure plate 312; the number of the connecting rod assemblies 340 is the same as the number of the fixing assemblies 330. In this embodiment, the number of the connecting rod assemblies 340 is 4, and every 2 are located at the two ends of the top of the pressure plate 312.

[0028] Reference Figure 6 and Figure 7 In this embodiment, the connecting rod assembly 340 includes a first guide rod 341, a limiting rod 342 and a connecting rod 343; One end of the first guide rod 341 is connected to the movable end of the pressing assembly 310 located inside the protective cover 320, the other end of the first guide rod 341 passes through the top of the protective cover 320 and is connected to the limiting rod 342, the other end of the limiting rod 342 is movably connected to the connecting rod 343, and the other end of the connecting rod 343 is movably connected to one end of the fixing assembly 330 located outside the protective cover 320.

[0029] The top of the first guide rod 341 passes through the top of the protective cover 320 and is connected to the limiting rod 342. The first guide rod 341 and the protective cover 320 are slidably matched, so that the first guide rod 341 can only move in the vertical direction, and the first guide rod 341 prevents the protective cover 320 from rotating, thereby preventing the protective cover 320 from rotating around the telescopic rod of the first telescopic member 311 due to external force, causing the protective cover 320 to rotate. 0 cannot enter the placement slot 111; the limiting rod 342 is set horizontally, and the bottom of the other end of the limiting rod 342 is hinged to one end of the connecting rod 343; the connecting rod 343 is set at an angle, and the other end of the connecting rod 343 is hinged to the end of the fixing component 330 located outside the protective cover 320, converting the vertical movement of the limiting rod 342 into the horizontal movement of the fixing component 330 to achieve a clamping action; the clamping is completed synchronously during the downward pressing process through the connecting rod assembly 340, which improves the response performance and reliability of the fixing component 330.

[0030] Reference Figure 6 and Figure 8 In this embodiment, the fixing assembly 330 includes a first sleeve 331 , a fixing block 335 and a first elastic member 336 ; The first sleeve 331 passes through the side wall of the protective cover 320 and is slidably connected to the protective cover 320, so that the first sleeve 331 serves as both a transmission component and a seal to prevent cement fragments from splashing out from the gap between the protective cover 320 and the first sleeve 331. The end of the first sleeve 331 located outside the protective cover 320 is movably connected to the connecting rod 343, and the end of the first sleeve 331 located inside the protective cover 320 is slidably connected to the fixed block 335. A first elastic member 336 is connected between the fixed block 335 and the inner wall of the first sleeve 331.

[0031] Specifically, refer to Figure 8 The fixing assembly 330 also includes a first sliding groove 332 opened in the first sleeve 331, and a first slider 333 is slidably installed in the first sliding groove 332. One side of the first slider 333 is connected to a first sliding rod 334, and the other end of the first sliding rod 334 extends to the outside of the first sleeve 331 and is connected to the fixed block 335. The first sliding rod 334 and the first sleeve 331 are slidably fitted together, and a first elastic member 336 is connected between the first slider 333 and the first sliding groove 332, and the first elastic member 336 is preferably a spring.

[0032] The first sleeve 331 is set horizontally. Preferably, the outer surface of the first sleeve 331 is set in a square shape to improve the stability of the first sleeve 331 when sliding. The first sleeve 331 converts the swing of the connecting rod 343 into horizontal movement, driving the fixed block 335 to move closer to or away from the cement block; the fixed block 335 directly contacts and clamps the side wall of the cement block to prevent the sample from sliding or tipping over during the test; the first sliding rod 334 is set horizontally, and a rubber dust ring (not shown in the figure) can be set between the first sliding rod 334 and the first sleeve 331 to prevent debris from entering the first slide groove 332. The first elastic member 336 provides a buffering force to avoid damage to the corners caused by the rigid collision between the fixed block 335 and the cement block, thereby improving the authenticity of the test data and allowing the fixed block 335 to adaptively adjust its position within a certain range to compensate for the dimensional error of the cement block; a pressure sensor (not shown in the figure) can also be installed inside the fixed block 335 to measure the force applied to the side wall of the cement block.

[0033] Reference Figure 7 and Figure 8 , by lowering the pressure plate 312, the connecting rod 343 pushes the first sleeve 331 to slide into the inside of the protective cover 320. After the fixed block 335 contacts the side wall of the cement block, the first elastic member 336 begins to stretch, generating an elastic clamping force in the reverse direction. At this time, the pressure plate 312 has not yet contacted the top of the cement block. The pressure plate 312 continues to descend, and the first slider 333 moves in the first slide groove 332, thereby driving the first sliding rod 334 to move into the first slide groove 332. The elastic force of the first elastic member 336 increases with the amount of stretching, so that the fixed block 335 can adaptively adjust its position within a certain range to avoid damage to the mechanism.

[0034] Reference Figure 6 and Figure 9 In this embodiment, the pressure testing system further includes a support mechanism 500, which is provided corresponding to the through hole 110 located at the third station. The support mechanism 500 is used to support the stripper plate 200 to prevent the press assembly 310 from damaging the stripper plate 200 when squeezing the cement block. Specifically, the support mechanism 500 is located directly below the through hole 110 of the third station.

[0035] Reference Figure 9 The support mechanism 500 includes a second sleeve 510 installed on the top of the base 20, and a second slide groove 520 is opened in the second sleeve 510. A second slider 530 is slidably installed in the second slide groove 520. One side of the second slider 530 is connected to the second sliding rod 540, and the other end of the second sliding rod 540 extends to the outside of the second sleeve 510 and is connected to the support plate 550. The support plate 550 is arranged horizontally, and the second sliding rod 540 and the second sleeve 510 are slidably matched. A second elastic member 560 is connected between the second slider 530 and the second slide groove 520, and the second elastic member 560 is preferably a spring.

[0036] The second sleeve 510 and the second sliding rod 540 are arranged vertically; at the third workstation, the support plate 550 is located directly below the through hole 110, and the length and width of the support plate 550 match the length and width of the bottom groove 114. The upper part of the support plate 550 enters the bottom groove 114 and contacts the bottom of the unloading plate 200, supporting the unloading plate 200, bearing the vertical load during the test, preventing the unloading plate 200 from being deformed or damaged due to overload, ensuring the flatness and sliding performance of the unloading plate 200, and extending the service life of the unloading plate 200.

[0037] Reference Figure 1 、 Figure 3 and Figure 4 The support mechanism 500 is connected to the linkage mechanism 400. When the pressing component 310 moves toward the through hole 110, the pressing component 310 drives the support mechanism 500 to rise through the linkage mechanism 400, so that the support mechanism 500 supports the unloading plate 200. When the pressing component 310 moves away from the through hole 110, the pressing component 310 drives the support mechanism 500 to descend through the linkage mechanism 400, so that the support mechanism 500 is separated from the unloading plate 200.

[0038] Specifically, the second sleeve 510 is connected to the linkage mechanism 400; the vertical movement of the pressing assembly 310 is converted into the lifting action of the support mechanism 500 through the linkage mechanism 400, realizing the linkage of "pressing down and supporting synchronously, rising and separating synchronously"; before the pressing plate 312 contacts the cement block, the support plate 550 has contacted the unloading plate 200, and the pressing plate 312 continues to descend, and the second slider 530 moves in the second slide groove 520, thereby driving the second sliding rod 540 to move into the second slide groove 520, and the second elastic member 560 is stretched, generating an elastic clamping force in the reverse direction, and the elastic force increases with the stretching amount, so that the support plate 550 can better support the unloading plate 200, and the support plate 550 can adaptively adjust its position within a certain range to avoid damage to the mechanism.
