Description

Technical Field

[0001] This utility model relates to the field of building engineering testing technology, and in particular to a mortar consistency testing device. Background Technology

[0002] Mortar is a key slurry used in construction engineering for bonding, masonry, plastering, and waterproofing. It is made by mixing cementitious materials and fine aggregates in a certain proportion. The consistency of mortar is the core indicator for measuring its fluidity. By accurately controlling the consistency value, the mortar can have good plasticity during construction, while avoiding the construction difficulties caused by excessive thinness leading to bleeding and segregation or excessive thickness.

[0003] In the existing technology, the mortar consistency testing device mainly consists of three parts: a test cone, a container, and a support. The top of the test cone has a rod. When testing the mortar consistency, some mortar is poured into the container. The rod is held and slid along the support to slowly release the test cone. When the bottom of the test cone contacts the mortar, the rod is fixed. After adjusting the measuring instrument, the rod is released and the depth to which the test cone freely falls into the mortar is measured, thereby testing the mortar consistency.

[0004] The test cone has a rod at the top and a through hole on the support that slides with the rod. When the test cone falls into the mortar, the rod slides along the inner wall of the through hole. At this time, the inner wall of the through hole slides in contact with the rod, which generates a certain frictional resistance on the rod. The depth of the test cone inserted into the mortar will decrease, causing a certain measurement error, and the data it reflects is not accurate enough. Utility Model Content

[0005] This invention provides a mortar consistency testing device that can reduce measurement errors and improve measurement accuracy.

[0006] The purpose and effect of this utility model of a mortar consistency testing device are achieved by the following specific technical means: a mortar consistency testing device includes a base, a mortar cylinder placed on the base, a rod with scale stickers set on the mortar cylinder, and a conical block installed at the bottom of the rod. A connecting plate is provided on one side of the rod, and a stabilizing component for positioning the rod to ensure that the conical block remains vertically descending is provided on one side of the connecting plate.

[0007] The stabilizing component includes a cylinder fixedly connected to one side of the connecting plate, and the cylinder is sleeved on the outside of the rod. The inner wall of the cylinder is equipped with four sets of guide wheels arranged in a ring, and the outer surface of each guide wheel is in contact with the outer surface of the rod.

[0008] The release assembly, located at the top of the connecting plate, is used to release the cone block from its grip, allowing it to descend automatically.

[0009] A connecting component, located on one side of the base and connecting plate, is used to adjust the height of the conical block.

[0010] Preferably, a set of support plates are fixedly connected to the outer surface of the cylinder, and an arc-shaped plate is fixedly connected to the top of each support plate.

[0011] Preferably, the release assembly includes a set of hanging plates disposed on one side of the rod body, each hanging plate having a clamping block fixedly connected to one end, and a retaining ring being disposed above the two clamping blocks, the inner wall of the retaining ring being connected to the outer surface of the rod body.

[0012] Preferably, a set of positioning plates is slidably connected to a set of the hanging plates, and a reinforcing plate is fixedly connected to the front and rear ends of the set of positioning plates, and the left end of each reinforcing plate is connected to one side of the connecting plate.

[0013] Preferably, a set of springs is fixedly connected to one side of each of the two reinforcing plates that are close to each other, and the other end of each spring is connected to the outer surface of the hanging plate.

[0014] Preferably, a top plate is provided between a group of the suspended plates, and a rotating rod is fixedly connected to the upper surface of the top plate. The top end of the rotating rod extends above the top end of the connecting plate, and the rotating rod is rotatably connected to the connecting plate.

[0015] Preferably, the connecting assembly includes a support block fixedly connected to one side of the base, a threaded rod rotatably connected to the upper surface of the support block, a movable block threadedly connected to the outer surface of the threaded rod, and one side of the movable block connected to the outer surface of the connecting plate.

[0016] Preferably, a set of guide plates are slidably connected to the movable block, and the bottom end of each guide plate is connected to the upper surface of the support block.

[0017] Beneficial effects:

[0018] 1. By installing four sets of guide wheels arranged in a ring on the inner wall of the cylinder, the outer surface of each guide wheel is in contact with the outer surface of the rod, which can guide the rod to descend in a vertical state, so that the cone block enters the mortar in a vertical state. This effectively eliminates the influence of verticality deviation on the test results, and can reduce the resistance of the rod and cone block falling, reduce measurement error, and improve the accuracy of measurement.

[0019] 2. The rod can be suspended and positioned by releasing the assembly. By turning the threaded rod through the set connecting assembly, the connecting plate can be raised and lowered so that the bottom of the cone block can be accurately placed on the top surface of the mortar. Compared with the sliding adjustment of the rod by hand, the adjustment method of the above structure is more accurate and easier to operate, which can improve the accuracy of mortar consistency detection.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] As attached Figure 1 To be continued Figure 4 As shown: A mortar consistency testing device includes a base 1, a mortar cylinder 2 placed above the base 1, a rod 3 with a scale sticker placed above the mortar cylinder 2, and a conical block 4 installed at the bottom of the rod 3. The mortar cylinder 2 is used to hold mortar. When the conical block 4 descends, the descent height of the rod 3 can be viewed from the scale sticker on the surface of the rod 3 and converted into a mortar consistency value.

[0028] As attached Figure 1 With appendix Figure 3As shown: A connecting plate 5 is provided on one side of the rod body 3. A release assembly 7 is provided on the top of the connecting plate 5 to release the conical block 4 and allow it to descend on its own. The release assembly 7 includes a set of lifting plates 701 provided on one side of the rod body 3. A clamping block 702 is fixedly connected to one end of each lifting plate 701. A retaining ring 703 is provided above the two clamping blocks 702. The inner wall of the retaining ring 703 is connected to the outer surface of the rod body 3. The lifting plates 701 can stabilize the clamping blocks 702 on the retaining ring 703. Below 03, a stable support is formed for the rod 3 and the conical block 4. A set of positioning plates 704 are slidably connected to a set of lifting plates 701. The front and rear ends of the set of positioning plates 704 are respectively fixedly connected to reinforcing plates 705. The left end of each reinforcing plate 705 is connected to one side of the connecting plate 5. By using the cooperation of positioning plates 704 and reinforcing plates 705, the clamping block 702 can be connected to the connecting plate 5, so that the rod 3 and the conical block 4 are stable on one side of the connecting plate 5.

[0029] As attached Figure 1 With appendix Figure 3 As shown: A set of springs 706 are fixedly connected to one side of each of the two reinforcing plates 705 that are close to each other. The other end of each spring 706 is connected to the outer surface of the hanging plate 701. The extension and contraction of the springs 706 can push the hanging plate 701, thereby applying a pushing force to the clamping block 702, further ensuring the effect of holding the rod 3. A top plate 707 is provided between the set of hanging plates 701. A rotating rod 708 is fixedly connected to the upper surface of the top plate 707. The top end of the rotating rod 708 extends above the top end of the connecting plate 5, and the rotating rod 708 is rotatably connected to the connecting plate 5. By rotating the rotating rod 708, the top plate 707 can be rotated to push the hanging plate 701, and the clamping block 702 will move away from the rod 3. The rod 3 and the conical block 4 will then fall automatically.

[0030] As attached Figure 1 With appendix Figure 2 As shown: One side of the connecting plate 5 is provided with a stabilizing component 6 for positioning the rod 3 to ensure that the conical block 4 remains vertically descending; the stabilizing component 6 includes a cylinder 601 fixedly connected to one side of the connecting plate 5, and the cylinder 601 is sleeved on the outside of the rod 3. The inner wall of the cylinder 601 is equipped with four sets of guide wheels 602 arranged in a ring, and the outer surface of each guide wheel 602 is in contact with the outer surface of the rod 3. When the rod 3 falls, the guide wheels 602 will guide the rod 3, enabling the rod to descend vertically. The rod 3 remains vertical, thus ensuring that the cone block 4 remains vertical as it enters the mortar, effectively eliminating the influence of verticality deviation on the test results. A set of support plates 603 are fixedly connected to the outer surface of the cylinder 601. Each support plate 603 has an arc plate 604 fixedly connected to its top. The arc plate 604 is located outside the rod 3 and has a gap between it and the rod 3. The arc plate 604 is used to limit the falling stroke of the rod 3 and prevent the retaining ring 703 from falling and hitting the guide wheel 602.

[0031] As attached Figure 1 With appendix Figure 4 As shown: Connecting component 8, located on one side of base 1 and connecting plate 5, is used to adjust the height of conical block 4. Connecting component 8 includes a support block 801 fixedly connected to one side of base 1. A threaded rod 802 is rotatably connected to the upper surface of support block 801. A movable block 803 is threadedly connected to the outer surface of threaded rod 802. One side of movable block 803 is connected to the outer surface of connecting plate 5. By rotating threaded rod 802, the height of connecting plate 5 can be adjusted so that conical block 4 is exactly above mortar, avoiding the problem of uneven initial velocity of conical block 4 due to excessive gaps in traditional manual operation, and improving the accuracy of mortar consistency detection. A set of guide plates 804 are slidably connected to movable block 803. The bottom end of each guide plate 804 is connected to the upper surface of support block 801. The guide plates 804 can stabilize movable block 803, so that movable block 803 can smoothly drive connecting plate 5 and conical block 4 to descend smoothly.

[0032] Working principle: When testing the consistency of mortar inside the mortar cylinder 2, first rotate the threaded rod 802 to raise and lower the connecting plate 5 until the bottom of the conical block 4 is above the mortar inside the mortar cylinder 2. Then rotate the rotating rod 708, which will cause the top plate 707 to rotate. The top plate 707 will push the two hanging plates 701 away, and at the same time, the hanging plates 701 will cause the clamping block 702 to disengage from the retaining ring 703. Then the conical block 4 will automatically descend, and the rod 3 will descend smoothly under the guidance of the guide wheel 602, ensuring that the conical block 4 descends in a vertical state, further ensuring the testing effect of mortar consistency.
