Description

Technical Field

[0001] This invention relates to the field of grouting material aggregate life testing technology. Specifically, it relates to an environmental durability tester for grouting material aggregates. Background Technology

[0002] Grouting utilizes hydraulic, pneumatic, or electrochemical principles to uniformly inject grout into the strata, surrounding rock, backfill, or lining through grouting pipes. The grout fills, penetrates, and compacts, expelling moisture and air from soil particles or rock fissures and occupying their positions. After a certain period, the grout and the originally loose soil particles or fissures bond together to form a strong, structurally sound, and chemically stable "stone body," achieving waterproofing. The lifespan of the grouting material's stone body needs to be evaluated to assess the effectiveness of the grouting project.

[0003] The current method involves using a lifetime testing instrument. This instrument includes a timer, pH meter, thermometer, acid tank, and sample stage containing acid. The effects of the environment on the stones are simulated by immersing them in the acid solution or acid mist. During the lifetime testing process, the samples need to be removed from the corrosive solution at regular intervals to test various parameters, such as unconfined compressive strength. The corrosive liquid on the stone surface must be wiped off before testing. Currently, personnel must remove the stone before wiping it. During this process, acid from the stone surface can easily drip onto the surface and surrounding area of ​​the lifetime testing instrument, causing corrosion to the instrument or other items, and even injuring personnel. Summary of the Invention

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0035] like Figures 1 to 5 As shown, the grouting material stone body environmental durability tester includes an immersion tank 2 and a sample stage 21 set in the immersion tank 2. The sample stage 21 is a support structure with a mesh surface, so that the bottom of the stone body sample block 100 placed on the sample stage 21 can fully contact the corrosive environment. The immersion tank 2 is connected to a circulation pump. The inlet of the circulation pump is connected to a solution preparation chamber through a pipeline. The solution preparation chamber contains prepared acid and alkali solutions. These acid and alkali solutions are circulated with the immersion tank 2 through the circulation pump. At the same time, during the circulation process, the temperature is controlled by heating elements and temperature sensors, and the acid and alkali solutions leading out of the immersion tank 2 are precipitated and filtered.

[0036] A top cover assembly is provided above the soaking tank 2. The top cover assembly includes a top shell 22, a wiping channel 40 disposed within the top shell 22, and an upper cover 1 covering the top of the wiping channel 40. First absorbent sheets 12 are provided on the front and rear sides of the wiping channel 40, and second absorbent sheets 13 are provided on the lower surface of the upper cover 1. Side cavities are respectively provided on the left and right sides of the wiping channel 40, and wiping claws 50 are slidably disposed in the side cavities. The two wiping claws 50 are arranged opposite each other and slide synchronously through a push-pull mechanism to apply pressure to the sample block 100. The wiping claw 50 is clamped, and a flexible third absorbent sheet 14 is provided on the opposite surface of the wiping claw 50. The wiping claw 50 includes a clamping plate 51 slidably disposed in the side cavity and a support plate slidably connected to the bottom of the clamping plate 51. A self-winding drum 59 higher than the clamping plate 51 is provided in the side cavity near the wiping channel 40. One end of the third absorbent sheet 14 is clamped on the support plate, and the other end of the third absorbent sheet 14 is wound around the upper surface of the support plate and the side of the clamping plate 51 facing the wiping channel 40 and then wound onto the self-winding drum 59.

[0037] The front and rear sides of the top of the wiping channel 40 are also provided with take-up rollers 43. The take-up rollers 43 are wound with hooks 42. There are at least two hooks 42. The two ends of each hook 42 are fixed on different take-up rollers 43. The two take-up rollers 43 are driven to rotate synchronously by a self-locking drive mechanism. The drive mechanism includes an operating part 46 that extends out of the top shell 22.

[0038] The first absorbent sheet 12 and the second absorbent sheet 13 wipe the front and rear sides and the top surface of the sample block 100, respectively. The third absorbent sheet 14 can wipe the left and right sides and the bottom surface of the sample block 100, thereby achieving all-round wiping of the sample block 100 and preventing the corrosive liquid on the surface of the sample block 100 from dripping into places outside the soaking tank 2.

[0039] like Figures 1 to 5 As shown, the tray includes a tray portion 54 that is integrally plate-shaped and a sliding plate portion 52 connected to the opposite side of the tray portion 54. The sliding plate portion 52 is slidably connected to the bottom of the clamping plate 51. A second hook block 521 is fixed to the free end of the sliding plate portion 52, and a first hook block 511 is fixed to the opposite side of the clamping plate 51. A tension spring 53 is connected to the first hook block 511, and the other end of the tension spring 53 is hooked onto the second hook block 521. Since the width of the sample block 100 varies, in order to adapt to sample blocks 100 of different widths, a wiping claw 50 with variable clamping width is provided to match sample blocks 100 of different widths. In addition, by changing the first absorbent layer of different thicknesses, it is possible to adapt to the wiping of sample blocks 100 of different lengths, and by changing the second absorbent layer of different thicknesses, it is possible to wipe sample blocks 100 of different heights.

[0040] When the wiping claws 50 move away, the free ends of the trays are not in contact, so the trays are in an extended state. When the two wiping claws 50 approach each other and the trays are pressed together, the clamping plates 51 approach each other under the pulling action of the first pull line 31, and the trays press against each other until the clamping plates 51 contact the sample block 100. Then the first pull line 31 is stopped, the trays support the sample block 100, and the third absorbent sheet 14 between the opposite surfaces of the clamping plates 51 contacts the left and right sides of the sample block 100, thus wiping the left and right sides of the sample block 100.

[0041] like Figures 1 to 3 , Figure 5 As shown, the lower side of the tray is provided with a cartridge groove, and a positioning post 55 is provided in the cartridge groove. The lower end of the third absorbent sheet 14 is clamped between the positioning post 55 and the cartridge groove. The positioning post 55 is snapped onto or fixed to the tray by bolts. Removing the positioning post 55 from the cartridge groove can release the third absorbent sheet 14, so as to facilitate the replacement of the third absorbent sheet 14 on the wiping claw 50.

[0042] The clamping plate 51 is provided with weight-reducing holes. The upper and lower ends of the clamping plate 51 are respectively provided with cylindrical cavities. The upper cylindrical cavity is provided with a first guide cylinder 57, and the lower cylindrical cavity is provided with a second guide cylinder 58. The upper end of the third absorbent sheet 14 is wound around the free end of the support plate, the upper surface of the support plate, the second guide cylinder 58, the opposite surface of the clamping plate 51, and the first guide cylinder 57 in sequence and then wound onto the take-up cylinder. Thus, the third absorbent sheet 14 is limited to the surface opposite to the wiping claw 50 by the guiding action of the first guide cylinder 57 and the second guide cylinder 58. The winding force of the self-retracting cylinder 59 is less than the tension of the tension spring 53. The third absorbent sheet 14, which is wound by the self-retracting cylinder 59, can keep the third absorbent sheet 14 in a flat state when the support plate slides relative to the clamping plate 51, so that the third absorbent sheet 14 can better contact the surface of the sample block 100 and achieve wiping.

[0043] like Figures 2 to 3 As shown, an inner shell 30 is provided inside the top shell 22, and the inner shell 30 forms a side cavity and a wiping channel 40. Figure 2 To illustrate the positional relationship between the inner shell 30 and the top shell 22, only a portion of the top shell 22 located at the front is shown. The clamping plate 51 is slidably connected to the front and rear side walls of the inner shell 30 via sliders 56. Specifically, the front side of the inner shell 30 is provided with a horizontal first slide rail 301 and a second slide rail 302 spaced apart, and the rear side of the inner shell 30 is provided with at least two horizontal second slide rails 302 spaced apart. The sliders 56 are slidably installed in the first slide rail 301 and the second slide rail 302 respectively. The first slide rail 301 is continuous from front to back, and a wire-inserting block 561 is fixed on the slider 56 located in the first slide rail 301. The wire-inserting block 561 extends out of the wiping channel 40, and two rope holes are vertically spaced apart on the wire-inserting block 561. The front side of the top shell 22 is provided with a first wire hole 221 and a second wire hole 222 located below the first wire hole 221.

[0044] like Figures 1 to 4 As shown, the push-pull mechanism includes a first pull handle 33, a second pull handle 34, a first pull wire 31 for moving the two clamping plates 51 toward the wiping channel 40, and a second pull wire 32 for moving the two clamping plates 51 away from each other. The first pull handle 33 is located outside the top shell 22. One end of the first pull wire 31 is fixed to the wire mounting block 561, and the other end passes through the first wire hole 221 and is fixed to the first pull handle 33.

[0045] A perforated wire-fixing block 35 is fixed to the front side of the inner shell 30. The wire-fixing block 35 is located on the side of the moving trajectory of the clamping plate 51 away from the wiping channel 40. One end of the second pull wire 32 is fixed to the wire-installing block 561, and the other end passes through the perforation of the wire-fixing block 35 and the second pull wire 32 and is fixed to the second pull handle 34. Figure 4 The diagram illustrates the arrangement of a first guy wire 31 and a second guy wire 32.

[0046] By setting up a push-pull mechanism, when the first pull line 31 is pulled outward, the two wiping claws 50 can be brought closer together, so that the third absorbent sheet 14 can contact the sample block 100. When the second pull line 32 is pulled outward, the two wiping claws 50 can be moved away, which facilitates the insertion of the sample block 100. Since the fixing block 35 is set on the outside of the clamping plate 51, the two clamping plates 51 can be separated when the second pull line 32 is pulled away from the tester.

[0047] like Figure 1 , Figure 3 As shown, the driving mechanism includes a worm gear 44 coaxially fixed to one end of the take-up roller 43. The take-up roller 43 is disposed in the space between the top shell 22 and the inner shell 30. An operating rod is rotatably disposed inside the top shell 22. The operating rod is provided with worm gear portions 45 that mesh with the two worm gears 44 respectively. The two worm gear portions 45 rotate in opposite directions. One end of the operating rod extends out of the top shell 22. An operating part 46 is connected to the operating rod. The operating part 46 can be a handle or a handwheel. The operating rod with the operating part 46 and meshing with the worm gears 44 drives the two worm gears 44 to move synchronously, thereby realizing the take-up and release of the wire catcher 42. In use, the wire catcher 42 is caught at the bottom of the sample block 100. The handle is turned to raise and lower the wire catcher 42 carrying the sample block 100. The center of the wire catcher 42 can also be connected by a net bag, which makes it easier to support the sample block 100.

[0048] When it is necessary to remove the sample block 100, first keep the upper cover 1 closed, and then lift the sample block 100 up through the guide wire 42 until the upper surface of the sample block 100 rests on the second absorbent sheet 13 on the lower side of the upper cover 1. During this process, the lifted sample block 100 passes through the first absorbent sheet 12 on the front and rear inner walls of the wiping channel 40, wiping the droplets on the front and rear sides of the sample block 100. The second absorbent sheet 13 wipes the droplets on the top surface of the sample block 100. After that, keep the position of the sample block 100, and use the push-pull mechanism to push the two wiping claws 50 closer to each other and stick to the sample block 100 so that the bottom surface and left and right sides of the sample block 100 can be wiped through the third absorbent sheet 14. Thus, the wiping of the six sides of the cubic sample block 100 is completed. Then, open the upper cover 1, and continue to lift the sample block 100 up through the guide wire 42 to expose the wiping channel 40 for easy handling by the staff.

[0049] like Figures 2 to 3 As shown, the inner shell 30 is provided with a plurality of outlet holes 41 located above the second absorbent plate 13. The two ends of the catcher wire 42 pass through the outlet holes 41 and are connected to the take-up roller 43. A scraping mechanism is provided inside the outlet holes 41. Specifically, the scraping mechanism is a brush part provided inside the outlet hole. The catcher wire 42 passes through the brush part to scrape off the droplets adhering to its own surface, preventing them from entering between the inner shell 30 and the outer shell. Alternatively, the scraping mechanism can be composed of multiple elastic sheets, with scraping holes or scraping slits opened in the middle of the elastic sheets. The catcher wire 42 passes through the scraping holes or scraping slits, and the hole walls or slit walls are used to scrape off the droplets on the catcher wire 42.

[0050] Based on the above embodiments, such as Figures 1 to 3 and Figure 6 As shown, ear plates 11 are provided on the left and right sides of the top cover 1. The top cover assembly includes a locking mechanism for locking the position of the ear plates 11. The locking mechanism includes a top groove 23 provided on the upper surface of the top shell 22, a composite pressure cover rotatably connected to the opposite side of the top groove 23, a locking groove provided on the side of the top groove 23, and a locking piece 25 slidably installed in the locking groove. The top groove 23 is located on the left and right sides of the wiping channel 40 corresponding to the position of the ear plates 11. The top groove 23 communicates with the wiping channel 40. The composite pressure cover can press on the ear plates 11 placed in the top groove 23 and is locked in position by the locking piece 25 extending out of the locking groove.

[0051] After the sample block 100 is lifted up by the lanyard to the top of the cover 1, the lanyard can no longer be rolled up. Then, the wiping claw 50 moves towards the middle and the third absorbent plate 14 wipes the sample block 100. After wiping, the locking plate 25 is completely retracted into the locking groove, the composite pressure cover is opened, the top cover 1 is taken out, and then the sample block 100 is lifted up by the lanyard until the wiping channel 40 is exposed. Then the sample block 100 can be easily taken away for testing.

[0052] As a further improvement to the above embodiments, such as Figures 1 to 3 and Figure 6 As shown, the top groove 23 includes a shallow groove section away from the wiping channel 40, a middle groove section adjacent to the wiping channel 40, and a deep groove section connecting the shallow groove section and the middle groove section;

[0053] The composite cover includes a base plate 24 rotatably connected to the shallow groove section away from the wiping channel 40, a contact plate 241 rotatably connected to the middle of the base plate 24 near the wiping channel 40, and a spring 242 fixedly connected to the lower surface of the contact plate 241. After the composite cover is locked by the locking mechanism, the end of the base plate 24 near the wiping channel 40 is suspended above the deep groove section, the end of the contact plate 241 near the wiping channel 40 presses against the ear plate 11, the base plate 24 and the ear plate 11 are misaligned, and the other end of the spring 242 abuts against the deep groove section.

[0054] The shallow groove section is adapted to the substrate 24 so that the substrate 24 covered with the composite cover can be laid flat. The depth of the middle groove section is greater than that of the shallow groove section. After the upper cover 1 is closed, the ear plate 11 is placed in the middle groove section. When the sample block 100 is not raised to the lower surface of the upper cover 1 and the composite cover is locked by the locking mechanism, the contact plate 241 presses on the ear plate 11 and, under the action of the spring 242, one end of the contact plate 241 located in the deep groove section moves upward to press against the lower surface of the substrate 24. The end of the contact plate 241 extending out of the deep groove section can press against the ear plate 11, and the contact plate 241 is basically in a horizontal state. Figure 6The rectangular frame with dashed lines schematically shows the position of the touch plate 241 when it is not lifted. As it moves upward in the wiping channel 40, it is wiped by the first absorbent sheets 12 fixed to the front and rear sides of the wiping channel 40. After the sample block 100 is lifted by the guide wire 42 and placed on top of the second absorbent sheet 13, it is wiped by the second absorbent sheet 13. The guide wire 42 continues to wind up, causing the sample block 100 to move upward a short distance. The upper cover 1 continues to move upward along with the sample block 100. At the same time, the touch plate 241 rotates about the inward-facing edge of the base plate 24, and the exposed outer end of the touch plate 241 tilts upward, reminding the operator that the sample block 100 has been moved up to top of the second absorbent sheet 13. At this point, the operator can stop the rotation of the operating part 46 and the winding of the guide wire 42. The rotatable contact plate 241 provides a buffer distance for the cable tray 42, which can reduce the pulling force caused by the operator rotating the operating part 46 after the cable tray 42 hits the sample block 100. Then, the push-pull mechanism is operated to drive the wiping claw 50 to clamp against the left and right sides of the sample block 100. The third absorbent sheet 14 is used to wipe the left and right sides and the lower surface of the sample block 100. After wiping, the locking mechanism is unlocked to release the composite cover. Under the elastic force of the spring 242, the composite cover automatically pops open. Then, the operator can take out the top cover 1 to see the sample block 100. After continuing to wind up the cable tray 42 and lift the sample block 100, the sample block 100 can be taken out for testing.

[0055] After the test is completed, the sample block 100 is placed on the guide wire 42 and held in place by the guide wire 42. Then, the two wiping claws 50 are separated by the push-pull mechanism to make way for the wiping channel 40 for the sample block 100. The operating part 46 is rotated to make the guide wire 42 release the wire synchronously and move the sample block 100 down until the sample block 100 is placed back on the sample stage 21 and the etching of the sample block 100 can continue.

[0056] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
