Description

Technical Field

[0001] The invention relates to the technical field of concrete detection, in particular to a concrete viscosity detection device for civil engineering. Background Art

[0002] Concrete is a raw material used in civil engineering. It is mainly formed into a specific shape through bonding or pouring through a mold. When using concrete, we generally need to add some water and admixtures to the concrete to make the concrete have a certain viscosity. However, the operator cannot directly understand the viscosity of the concrete, and thus cannot guarantee the quality of the concrete after pouring, so a viscosity detection device is needed.

[0003] A patent with publication number CN207850865U discloses a concrete viscosity detection device for civil engineering. However, when using the above device, two relatively set pull rings need to be manually pulled to perform compression and tensile tests on the concrete, making it difficult for the operator to ensure that the pull rings on both sides move synchronously. If the two pull rings are not pulled synchronously, the force applied by the push plate to the concrete will be different in different areas, resulting in uneven stress distribution inside the concrete. This uneven stress distribution will affect the failure mode of the concrete during the tensile or shear separation process, and then cause the tensile test value to deviate from the true value. Summary of the invention

[0004] The present application provides a concrete viscosity detection device for civil engineering, which can improve the accuracy of concrete viscosity detection.

[0005] To achieve the above objectives, the present application discloses the following technical solutions:

[0006] A concrete viscosity detection device for civil engineering includes a base, a first sliding seat, a second sliding seat, a first detection block, a tensiometer, a second detection block and a sliding mechanism, wherein the first sliding seat and the second sliding seat are arranged opposite to each other in a first direction; a first containing groove is provided on the first detection block, and the first detection block is fixedly arranged on the first sliding seat; the tensiometer is fixedly arranged on the second sliding seat; a second containing groove is provided on the second detection block, and the second containing groove is arranged opposite to the first containing groove in the first direction; the second detection block is fixedly connected to the pull rod of the tensiometer; the sliding mechanism is arranged on the base, and the sliding mechanism is used to drive the first sliding seat and the second sliding seat to slide synchronously in opposite directions in the first direction.

[0007] In an embodiment of the present application, the first sliding seat and the second sliding seat are arranged opposite to each other in the first direction, and respectively fix the first detection block and the dynamometer. The dynamometer is connected to the second detection block through a pull rod. The receiving grooves opened on the two detection blocks are used to accommodate concrete samples. The sliding mechanism is arranged on the base, and is used to automatically drive the first sliding seat and the second sliding seat to slide synchronously in opposite directions in the first direction, thereby ensuring that the force applied by the first detection block and the second detection block to the concrete sample is always evenly distributed, effectively solving the problem of force distribution difference caused by asynchronous left and right pulling in the manual pull ring method, and avoiding local stress concentration or stress distribution deviation of the concrete sample due to uneven force during the test process.

[0008] In some possible embodiments, the sliding mechanism includes a first connecting rod, a second connecting rod, a third connecting rod, a first sliding plate, a first connecting plate, a second sliding plate, a second connecting plate and a first telescopic device, wherein the middle part of the first connecting rod is rotatably mounted on the base; the second connecting rod is consistent with the third connecting rod in length, one end of the second connecting rod is hinged to one end of the first connecting rod, one end of the third connecting rod is hinged to the other end of the first connecting rod; the other end of the second connecting rod is hinged to the middle part of the first sliding plate; the first detection block is fixedly mounted on the first sliding plate through the first connecting plate; the other end of the third connecting rod is hinged to the middle part of the second sliding plate, and the second sliding plate and the first sliding plate are arranged oppositely in the first direction; the second detection block is fixedly mounted on the second sliding plate through the second connecting plate; the first telescopic device is fixedly arranged on the base, and the telescopic rod of the first telescopic device is fixedly connected to the first sliding plate. In this way, the first telescopic device can be used as a power source to convert its own telescopic motion into a linear sliding motion of the first sliding plate, and the second connecting rod is pushed to make the first connecting rod rotate around its rotation point with the base, and when the first connecting rod rotates, its other end drives the third connecting rod hinged thereto to move.

[0009] According to the lever principle, the other end of the first connecting rod will drive the third connecting rod to move in the opposite direction, so the third connecting rod will drive the second sliding plate to slide in the first direction in a synchronous direction with the first sliding plate. In this way, the first detection block fixedly mounted on the first sliding plate through the first connecting plate and the second detection block fixedly mounted on the second sliding plate through the second connecting plate are synchronized and slid in the opposite direction, which effectively avoids the problem of asynchrony and ensures that the internal stress of the concrete is evenly distributed when the concrete is stretched or squeezed, so that the tensile test value is closer to the true value, and the accuracy of the concrete viscosity test is improved.

[0010] In some possible implementations, a plurality of first through holes are provided on the second connecting plate, and the central axis of each first through hole is parallel to the first direction. The concrete viscosity detection device for civil engineering also includes a plurality of guide rods, and the plurality of guide rods are arranged one-to-one with the plurality of first through holes. One end of each guide rod is fixedly connected to the second detection block, and the other end of each guide rod is slidably inserted into its corresponding first through hole in the first direction. In this way, on the one hand, it can provide guidance for the relative displacement between the second detection block and the tensile gauge in the process of the second sliding seat moving away from the first sliding seat; on the other hand, the guide rod can transfer part of the gravity of the second detection block to the second connecting plate, thereby reducing the interference of the second detection block's own weight on the force applied during the detection process, thereby improving the detection accuracy.

[0011] In some possible implementations, the first sliding plate and the second sliding plate are both slidably arranged on the base through the cooperation of the slide rail and the slider, so that the resistance during the sliding process is reduced, and the synchronous sliding of the first sliding seat and the second sliding seat is smoother.

[0012] In some possible implementations, the concrete viscosity detection device for civil engineering further includes a clamping assembly, the clamping assembly includes a second telescopic device and a push plate, the second telescopic device is fixedly arranged on the first sliding seat, the push plate is movably arranged in the first containing groove, a second through hole is provided on the first detection block, the central axis of the second through hole is parallel to the first direction, and the telescopic rod of the second telescopic device is fixedly connected to the push plate through the second through hole. In this way, when in use, the first detection block and the second detection block can be aligned together by controlling the sliding mechanism, so that the notch of the first containing groove and the notch of the second containing groove overlap, and then the concrete is put in, and then the telescopic rod of the second telescopic device is controlled to extend to drive the push plate to apply an extrusion force to the concrete, so that the concrete particles are further squeezed and filled with each other, the internal gap is reduced, and the overall state of the concrete is more uniform. In this way, the stress state of concrete in actual engineering can be simulated, and when the viscosity and other performance tests are performed later, the test results can more accurately reflect the real performance of the concrete and avoid the detection error caused by local unevenness.

[0013] In addition, when the detection is completed, the telescopic rod of the second telescopic device can be controlled to extend to drive the push plate to push out the concrete in the first containing groove, thereby facilitating the cleaning of the first containing groove.

[0014] In some possible implementations, there are two first telescopic devices, and the two first telescopic devices are symmetrically arranged about the rotation axis of the first connecting rod. In this way, when driving the first sliding plate to move, more stable support and power can be provided, ensuring that the first sliding plate moves smoothly along a predetermined direction, and ensuring the stability of the operation of the entire detection device.

[0015] In some possible implementations, a limit frame is provided on the second sliding seat, the tensile gauge is provided in the limit frame, and the concrete viscosity detection device for civil engineering further includes a fixed seat, and the tensile gauge is provided in the limit frame through the fixed seat. In this way, the tensile gauge can be positioned, and the tensile gauge is stably installed in the limit frame, ensuring that the tensile gauge will not be displaced during the detection process, thereby ensuring the accuracy of the tension measurement.

[0016] In some possible implementations, the concrete viscosity detection device for civil engineering further includes a recovery component, the recovery component includes a collection frame, a first through groove is provided on the first connecting plate, a second through groove is provided on the second connecting plate, the collection frame is penetrated through the first through groove and the second through groove, the length of the collection frame is greater than the maximum distance between the opposite surfaces of the first connecting plate and the second connecting plate, the orthographic projections of the first containing groove and the second containing groove on the second plane are located within the orthographic projection of the collection frame on the second plane, and the second plane is parallel to the first direction and perpendicular to the height direction of the base. In this way, without affecting the normal sliding of the first sliding seat and the second sliding seat in the first direction, it is effectively prevented that the concrete falls on the sliding mechanism when the concrete is pulled apart.

[0017] In some possible implementations, the collection frame is tilted, a discharge port is provided at one end of the collection frame at a lower height, and the recycling assembly further includes a collection box, which is provided directly below the discharge port. In this way, gravity can be used to allow concrete waste in the collection frame to automatically slide into the collection box, thereby improving the efficiency of concrete cleaning.

[0018] In some possible implementations, the recycling assembly further includes two support frames, each of which includes a support column and a support plate, and the support plate includes a first wall plate and a second wall plate connected together, the first wall plate is parallel to the lower surface of the collection frame, and the second wall plate is perpendicular to the first wall plate and the first direction; the two support frames are symmetrically arranged about the collection frame, and the lower surface of the collection frame is supported on the first wall plate; the height of each second wall plate is greater than the thickness of the bottom plate of the collection frame. In this way, the movement of the collection frame in the first direction can be limited by the second wall plate, and the collection frame can be prevented from being displaced due to the sliding of the first connecting plate and / or the second connecting plate in the first direction. At the same time, the first wall plate provides additional support force for the collection frame, ensuring that the collection frame remains stable during the entire detection and collection process.

The sliding mechanism 70 is arranged on the base 10, and is used to automatically drive the first sliding seat 20 and the second sliding seat 30 to slide synchronously in the opposite directions in the first direction, so as to ensure that the force applied by the first detection block 40 and the second detection block 60 to the concrete sample is always evenly distributed, effectively solving the problem of force distribution difference caused by asynchronous left and right pulling in the manual pull ring method, and avoiding the situation where local stress concentration or stress distribution deviation occurs in the concrete sample due to uneven force during the test process.

[0036] See also Figure 2 In some embodiments, a limit frame 301 is provided on the second sliding seat 30, and the tensile meter 50 is provided in the limit frame 301. The concrete viscosity detection device for civil engineering further includes a fixing seat 502, and the tensile meter 50 is provided in the limit frame 301 through the fixing seat 502.

[0037] See also Figure 3 Combined with Figure 4In some embodiments, the sliding mechanism 70 includes a first connecting rod 701, a second connecting rod 702, a third connecting rod 703, a first sliding plate 704, a first connecting plate 705, a second sliding plate 706, a second connecting plate 707 and a first telescopic device 708. The middle part of the first connecting rod 701 is rotatably mounted on the base 10; the second connecting rod 702 is consistent with the third connecting rod 703 in length, one end of the second connecting rod 702 is hinged to one end of the first connecting rod 701, and one end of the third connecting rod 703 is hinged to the other end of the first connecting rod 701; the second connecting rod 702 is hinged to one end of the first connecting rod 701, and the third connecting rod 703 is hinged to the other end of the first connecting rod 701. The other end of the connecting rod 702 is hinged to the middle of the first sliding plate 704; the first detection block 40 is fixedly mounted on the first sliding plate 704 through the first connecting plate 705; the other end of the third connecting rod 703 is hinged to the middle of the second sliding plate 706, and the second sliding plate 706 and the first sliding plate 704 are arranged opposite to each other in the first direction; the second detection block 60 is fixedly mounted on the second sliding plate 706 through the second connecting plate 707; the first telescopic device 708 is fixedly arranged on the base 10, and the telescopic rod of the first telescopic device 708 is fixedly connected to the first sliding plate 704. Exemplarily, the first telescopic device 708 can be an electric cylinder. Of course, the present application is not limited to this. In other embodiments, the first telescopic device 708 can also be a hydraulic cylinder or a pneumatic cylinder. It can be understood that the fixing method of the first telescopic device 708 can be designed with reference to the fixing method of the dynamometer 50, which will not be repeated here.

[0038] In this way, the first telescopic device 708 can be used as a power source to convert its own telescopic movement into a linear sliding movement of the first sliding plate 704, pushing the second connecting rod 702 to cause the first connecting rod 701 to rotate around its rotation point with the base 10. When the first connecting rod 701 rotates, its other end drives the third connecting rod 703 hinged thereto to move.

[0039] According to the lever principle, the other end of the first connecting rod 701 will drive the third connecting rod 703 to move in the opposite direction, so the third connecting rod 703 will drive the second sliding plate 706 to slide in the first direction in a synchronous direction with the first sliding plate 704. In this way, the first detection block 40 fixedly mounted on the first sliding plate 704 through the first connecting plate 705 and the second detection block 60 fixedly mounted on the second sliding plate 706 through the second connecting plate 707 are synchronized and slid in the opposite direction, which effectively avoids the problem of asynchrony and ensures that the internal stress of the concrete is evenly distributed when the concrete is stretched or squeezed, so that the tensile test value is closer to the true value, and the accuracy of the concrete viscosity test is improved.

[0040] See also Figure 4In some embodiments, the first sliding plate 704 and the second sliding plate 706 are slidably disposed on the base 10 through the slide rail 709 and the slider 7010.

[0041] See also Figure 4 In some embodiments, the number of the first telescopic devices 708 is two, and the two first telescopic devices 708 are symmetrically arranged about the rotation axis of the first connecting rod 701. In this way, when driving the first sliding plate 704 to move, more stable support and power can be provided to ensure that the first sliding plate 704 moves smoothly along the predetermined direction, thereby ensuring the stability of the operation of the entire detection device.

[0042] See also Figure 5 Combined with Figure 6 In some embodiments, a plurality of first through holes 7071 are provided on the second connecting plate 707, and the central axis of each first through hole 7071 is parallel to the first direction.

One end of each guide rod 80 is fixedly connected to the second detection block 60, and the other end of each guide rod 80 is slidably penetrated in the first direction through the corresponding first through hole 7071. In this way, on the one hand, it can provide guidance for the relative displacement between the second detection block 60 and the dynamometer 50 in the process of the second sliding seat 30 moving away from the first sliding seat 20; on the other hand, the guide rod 80 can transfer part of the gravity of the second detection block 60 to the second connecting plate 707, thereby reducing the interference of the deadweight of the second detection block 60 on the force applied during the detection process, thereby improving the detection accuracy.

[0043] See also Figure 7 In some embodiments, the concrete viscosity detection device for civil engineering further includes a clamping assembly 90, which includes a second telescopic device 901 and a push plate 902. The second telescopic device 901 is fixedly arranged on the first sliding seat 20, and the push plate 902 is movably arranged in the first containing groove 401. A second through hole 402 is provided on the first detection block 40, and the central axis of the second through hole 402 is parallel to the first direction. The telescopic rod of the second telescopic device 901 is fixedly connected to the push plate 902 through the second through hole 402. It can be understood that the specific structure of the second telescopic device 901 can be designed with reference to the specific structure of the first telescopic device 708, and will not be repeated here. This application only schematically gives an example in which the number of the second telescopic devices 901 is 3. This cannot be regarded as a special limitation to the present application. In other embodiments, the number of the second telescopic devices 901 can also be 1, 2 or 4, etc.

[0044] In this way, when in use, the first detection block 40 and the second detection block 60 can be aligned together by controlling the sliding mechanism 70, so that the notch of the first holding slot 401 and the notch of the second holding slot 601 overlap, and then concrete is put in, and then the telescopic rod of the second telescopic device 901 is controlled to extend to drive the push plate 902 to apply extrusion force to the concrete, so that the concrete particles are further squeezed and filled with each other, reducing the internal gaps and making the overall state of the concrete more uniform. In this way, the stress state of concrete in actual engineering can be simulated, and when the viscosity and other performance tests are performed later, the test results can more accurately reflect the real performance of the concrete and avoid detection errors caused by local unevenness. In addition, when the test is completed, the telescopic rod of the second telescopic device 901 can be controlled to extend to drive the push plate 902 to push out the concrete in the first holding slot 401, thereby facilitating the cleaning of the first holding slot 401.
