Description

Technical Field

[0001] This utility model relates to the field of civil engineering testing technology, and in particular to a device for monitoring changes in the fluidity of solidified fluid. Background Technology

[0002] Fluidized solidified soil refers to a backfill material formed by mixing water and a solidifying agent into soil. The soil includes silt, clay, sand, mud, and weathered gravel. After being poured and molded, it has a certain strength and has the advantages of high fluidity, self-compacting, and local sourcing. It is mainly used for reinforcing roadbeds, building foundations, and other parts, as well as for backfilling areas such as mining subsidence areas, gaps behind retaining walls, and around underground pipe corridors. It is particularly effective for backfilling narrow, elongated, and irregularly shaped non-structural areas. Before using fluidized solidified soil for construction, its fluidity must be tested.

[0003] In existing technologies, such as the fluidity measurement device for solidified soil with patent number CN221174282U, the placement tube is raised to a certain height, sealed with a conical cylinder, and then the conical cylinder is moved downward to allow the solidified soil to flow onto the placement plate. The fluidity is then detected using test rings on the placement plate. This causes the solidified soil to be subjected to gravitational acceleration at a certain height, resulting in an initial velocity that affects the accuracy of the measurement of the solidified soil's fluidity. Furthermore, the gradual descent of the conical cylinder causes the initial velocity of the solidified soil to change continuously, further exacerbating the impact on measurement accuracy. In addition, the test rings on the placement plate are prone to wear after prolonged use, affecting the measurement effect. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1-5 This utility model provides a device for monitoring changes in the fluidity of solidified fluid, comprising:

[0034] The base 1 has a groove in the center of its top surface, and a test ring 2 is fixedly connected in the groove.

[0035] A transparent plate 3 is positioned directly above the test ring 2. A test groove is provided at the top of the transparent plate 3. A connector is provided on the base 1. The connecting end of the connector is connected to the transparent plate 3 so that the transparent plate 3 and the base 1 can be detachably connected.

[0036] A support plate 4 is positioned directly above the transparent plate 3. A lifting component is mounted on the base 1, with the lifting end of the lifting component connected to the support plate 4. A through groove is provided on the support plate 4 along the vertical direction corresponding to the center of the test ring 2, and a placement tube 5 is installed in the through groove. A vibration damping component is mounted on the support plate 4, with the damping end of the vibration damping component connected to the placement tube 5.

[0037] This utility model features a transparent plate 3 covering the test ring 2, and a connector on the base 1 detachably connects the transparent plate 3 to the base 1. Thus, during each test of the fluidity of the solidified soil, the test groove of the transparent plate 3 holds the solidified soil, and the fluidity is measured through the test ring 2 via the transparent plate 3. After the test, the transparent plate 3 is disassembled for cleaning and then repositioned for the next test. This process avoids interference with the test ring 2, ensuring the accuracy of the scale on the test ring 2 and effectively extending its service life. Furthermore, a lifting mechanism controls the raising and lowering of the support plate 4, and a placement tube 5 is installed in the central slot of the support plate 4 to hold the solidified soil. The support plate 4 is equipped with vibration damping components to improve the stability of the placement tube 5 during lifting, enhancing the flow simulation effect and improving the measurement accuracy of the solidified soil.

[0038] Specifically, the bottom end of the placement tube 5 is attached to the inner wall of the bottom end of the test tank, and then fluidized solidified soil is filled into the placement tube 5. Then, the support plate 4 is lifted by the lifting device. The slight vibration generated during the rise of the support plate 4 is directly absorbed and isolated by the vibration damping device, forming vibration damping protection for the placement tube 5, thereby improving the flow simulation effect.

[0039] Furthermore, the vibration damping component includes a collar 6, which is fixed to the outer periphery of the through groove. A step 7 is provided on the top surface of the collar 6 near the inner ring side. A retaining ring 8 is fixed to the outer periphery of the top end of the placement tube 5 and is embedded in the step 7.

[0040] By fixing the collar 6 to the support plate 4, and embedding the retaining ring 8, which is fixed to the outer periphery of the placement tube 5, into the step 7 opened on the inner ring side of the collar 6, the connection stability between the placement tube 5 and the support ring is improved.

[0041] Furthermore, it also includes: several vibration dampers 9, which are arranged at equal intervals around the top of the step 7, and the two ends of the vibration dampers 9 are fixedly connected to the collar 6 and the retaining ring 8 respectively.

[0042] By fixing both ends of the vibration damper 9 to the collar 6 and the retaining ring 8 respectively, a vibration damping support is formed between the support plate 4 and the placement tube 5. It is understood that the diameter of the through groove is larger than the outer diameter of the placement tube 5, ensuring that the support plate 4 does not contact the inner wall of the placement tube 5. In this technical solution, the vibration damper 9 adopts a common structure with a vibration damping spring wound around the piston connecting rod, which is a conventional structure and will not be described in detail.

[0043] Furthermore, the outer periphery of the collar 6 is threaded, and the top of the collar 6 is threadedly connected to the end cap 10. The center of the end cap 10 is provided with a through hole that matches the through groove, and the inner wall of the top of the end cap 10 abuts against the top of the collar 6.

[0044] By threading the end cap 10 to the collar 6, the end cap 10 abuts against the collar 6, thereby limiting the collar 6 and causing the collar 6 to squeeze the vibration damper 9, thus achieving the vibration damping effect of the vibration damper 9. Specifically, when the end cap 10 abuts against the collar 6, a gap is provided between the collar 6 and the top of the step 7 to ensure that the vibration damper 9 has enough space to expand and contract to absorb energy and dampen vibration.

[0045] Furthermore, the lifting components include:

[0046] A servo motor 11 is fixedly connected inside the base 1. A screw 12 is coaxially fixed to the output shaft of the servo motor 11, and the screw 12 extends vertically upward.

[0047] The lifting seat 14 is fixedly connected to one side of the base 1. A sliding groove is provided inside the lifting seat 14. The screw 12 is rotated into the sliding groove. The screw 12 is threaded with a slider 13. The slider 13 is slidably connected into the sliding groove. One side of the slider 13 extends out of the sliding groove and is fixedly connected to the support plate 4.

[0048] The servo motor 11 drives the screw 12 to rotate, and the screw 12 is threaded with a slider 13 that slides in the groove, so that the slider 13 drives the support plate 4 to lift and adjust.

[0049] Furthermore, the connector includes:

[0050] A pair of card plates 15 are arranged opposite each other on both sides of the base 1. A connecting groove is provided on the side wall of the base 1. A rotating shaft 16 is inserted through the bottom of the card plate 15. The two ends of the rotating shaft 16 are rotated to the opposite side of the inner wall of the connecting groove. The top of the card plate 15 is engaged with the card slot provided on the side wall of the transparent plate 3. The number of card slots and card plates 15 are the same and correspond one-to-one. The card plate 15 has an elastic tendency to move towards the card slot.

[0051] A pair of card plates 15 are arranged opposite each other on both sides of the base 1 and away from the lifting seat 14, so that the card plates 15 can be easily engaged with the card slots, thereby stably fixing the transparent plate 3 on the top surface of the base 1.

[0052] Transparent panel 3 can be made of common glass or plastic.

[0053] Furthermore, it also includes:

[0054] A torsion spring 17 is wound around a rotating shaft 16, and the two ends of the torsion spring 17 are fixedly connected to the clamping plate 15 and the inner wall of the connecting groove, respectively.

[0055] The control plate 18 is fixed to the side wall of the rotating shaft 16 away from the clamping plate 15, and the control plate 18 extends downward at an angle away from the clamping plate 15 and the base 1. A fixing plate 21 is fixed to the side wall of the connecting groove. The fixing plate 21 has a ball joint groove near the control plate 18. A locking hole is opened on the side wall of the control plate 18. A small ball 19 is elastically slidable in the locking hole. The part of the small ball 19 that extends out of the locking hole is engaged with the ball joint groove.

[0056] Specifically, a clamp is provided between the control plate 18 and the clamping plate 15. Under the action of the rotating shaft 16 rotating at the center limit, the clamping plate 15 can be inserted into the slot to fix the transparent plate 3 by pressing it. The elastic tendency provided by the torsion spring 17 can maintain the fixation stability. When it is necessary to remove the transparent plate 3, simply press the control plate 18 to make the control drive ball 19 slide. When the ball 19 elastically engages with the clamping hole, the clamping plate 15 disengages from the transparent plate 3 and remains stable, making it easy to remove the transparent plate 3.

[0057] In this technical solution, a support spring 20 is provided inside the card hole. The two ends of the support spring 20 are fixedly connected to the ball 19 and the inner side wall of the card hole, respectively, so as to realize the elastic connection between the ball 19 and the control board 18.

[0058] Furthermore, the card plate 15 has an L-shaped structure, and the short side of the card plate 15 is engaged with the card slot.

[0059] The card plate 15 is designed in an L-shape to facilitate the engagement of the short plate of the card plate 15 with the card slot.

[0060] This utility model provides the working principle of a device for monitoring changes in the fluidity of solidified fluid:

[0061] The placement tube 5 is moved to the top surface of the transparent plate 3 and attached. Fluidized solidified soil is introduced into the placement tube 5 through the through hole, and then the test is started. The servo motor 11 is started to rotate the screw 12, and the slider 13 drives the support plate 4 to rise. The support plate 4 lifts the placement tube 5, so that the fluidized solidified soil flows outward along the center of the transparent plate 3 and then passes through the test ring 2 for flow testing. During the lifting process of the support plate 4, the vibration damper 9 can dampen and support the collar 6, and the end cap 10 stably limits the placement tube 5 on the support plate 4, improving the lifting stability of the placement tube 5 and improving the measurement effect.
