Description

Technical Field

[0001] This utility model relates to the field of cement mortar testing technology, and in particular to a cement mortar flowability tester. Background Technology

[0002] The cement mortar flowability tester is a specialized device used to test the flowability of mortars in materials such as pozzolanic silicate cement and composite silicate cement. This instrument assesses the flowability of cement by vibrating the mortar and measuring its diffusion diameter, providing a basis for determining the standard consistency water requirement.

[0003] When using the existing cement mortar flowability tester, the operator must first accurately place the truncated cone mold in the center of the worktable, and then complete the filling and compaction of cement mortar in two layers: For the first layer, use a small spoon to evenly add mortar from the edge of the mold to the center until the mortar is slightly higher than the top of the mold. Then, use a 20mm diameter tamping rod to tamp the mortar 25 times in a clockwise spiral motion from the edge to the center. During the tamping process, the tamping rod must be inserted vertically and penetrate the entire mortar layer. After the first layer is compacted, the second layer of mortar is filled, again to a level slightly higher than the top of the mold. Then, use the tamping rod to tamp the mortar 15 times in the same way. After tamping, use a knife to scrape off the excess mortar along the top of the mold so that the mortar surface is flush with the top surface of the mold.

[0004] However, when performing filling, tamping, and leveling operations, workers are prone to problems such as improper control of operating force, slight vibration of the table, or accidental hand contact, which can cause the truncated cone mold to deviate from the center of the table, or even tilt or shift. To avoid displacement of the truncated cone mold, operators need to pay extra attention to control the range of hand movements, which not only increases the difficulty of operation and reduces experimental efficiency, but may also cause them to neglect the uniformity of mortar filling due to excessive focus on mold positioning, thus affecting the experimental data. Therefore, a cement mortar flowability tester is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example 1 like Figures 1-5 As shown, the cement mortar flowability tester proposed in this utility model includes a support base, a drive assembly, a jumping assembly, a limiting mechanism, and a sliding mechanism. The support base includes a base 6 and multiple support frames 5, which are arranged in a circular array and fixedly installed on the upper surface of the base 6. The drive assembly includes a drive motor 3, a motor mounting cylinder 10, a cam 7, a transmission rod 8, and a side plate 9. The motor mounting cylinder 10 is fixed on one of the support frames 5. The drive motor 3 is fixedly mounted on the outer wall of the motor mounting cylinder 10. Its output shaft passes through the motor mounting cylinder 10 and is coaxially and fixedly connected to the transmission rod 8. The side plate 9 is vertically mounted on the upper end face of the base 6. The end of the transmission rod 8 away from the drive motor 3 is rotatably connected to the side plate 9. The cam 7 is fixedly sleeved on the outer wall of the transmission rod 8. The jumping component is mounted above multiple support frames 5, and its transmission end abuts against the cam 7; An L-shaped support plate 13 is fixedly installed on the side of the base 6. A sliding mechanism is installed on the support plate 13 and located directly above the jumping component. A first connecting block 28 is connected to the side of the sliding mechanism facing the truncated cone mold 23. A limiting mechanism is installed on the outside of the first connecting block 28 and can limit the truncated cone mold 23.

[0028] It should be noted that the drive motor 3 is a three-phase asynchronous motor, which is coaxially fixedly connected to one end of the transmission rod 8 through a flexible coupling. The flexible coupling can compensate for the coaxiality error between the transmission rod 8 and the motor output shaft, and reduce transmission impact.

[0029] The end of the transmission rod 8 away from the drive motor 3 is rotatably connected to the side plate 9 through a deep groove ball bearing to ensure that the transmission rod 8 has no radial offset during rotation. The cam 7 is made of 45 steel and is fixedly sleeved in the middle of the outer wall of the transmission rod 8 by a flat key to ensure that the cam 7 rotates synchronously with the transmission rod 8. The contour curve of the cam 7 is designed according to the jumping height of the tabletop 24.

[0030] The sliding cylinder 1 is a cylindrical hollow structure made of stainless steel tube. The axis of the sliding cylinder 1 coincides with the central axis of the base 6, providing vertical sliding guidance for the column 2.

[0031] In this embodiment, the jumping component includes a sliding cylinder 1, a column 2, a stop block 14, and a jumping table surface 24. The sliding cylinder 1 is vertically arranged and fixedly connected to multiple support frames 5, providing sliding guidance for the column 2. The column 2 slides through the sliding cylinder 1, and its top end is coaxially fixedly connected to the jumping table surface 24. A truncated cone mold 23 is placed on the jumping table surface 24, and the truncated cone mold 23 can be used to hold cement mortar. A stop block 14 is fixedly installed at the bottom end of the column 2, and the stop block 14 abuts against the outer peripheral surface of the cam 7. The limiting mechanism can form a circumferential limiting for the truncated cone mold 23.

[0032] It should be noted that when the cam 7 rotates, it pushes the column 2 upward through the abutment block 14, and the column 2's own weight causes the tabletop 24 to bounce periodically.

[0033] In this embodiment, the limiting mechanism includes a first limiting ring 11, two second connecting blocks 29, two second limiting rings 30, and a limiting assembly. The first limiting ring 11 is fixed to the side of the first connecting block 28 facing the truncated cone mold 23. The two second connecting blocks 29 are respectively hinged to the two sides of the first connecting block 28, and their ends away from the first connecting block 28 are respectively fixedly connected to the corresponding second limiting rings 30. The ends of the two second limiting rings 30 away from the second connecting blocks 29 are detachably connected through the limiting assembly, and together with the first limiting ring 11, they enclose a limiting space that adapts to the outer wall of the truncated cone mold 23, thereby achieving all-round encirclement and limiting of the truncated cone mold 23. The limiting assembly includes two fixing blocks 26, a butterfly bolt 25, and a fixing nut 31. The two fixing blocks 26 are respectively fixedly connected to the ends of the corresponding second limiting rings 30. One of the fixing blocks 26 has a fixing groove 32, and the fixing nut 31 is embedded in the fixing groove 32 to ensure the installation stability of the fixing nut 31. The butterfly bolt 25 passes horizontally through the two fixing blocks 26 and is threadedly connected to the fixing nut 31.

[0034] It should be noted that the two second limiting rings 30 can be fixed by tightening the butterfly bolt 25, and the second limiting rings 30 can be opened by loosening the butterfly bolt 25, which makes it easier to put on and take off the truncated cone mold 23.

[0035] In this embodiment, the sliding mechanism includes a first limiting plate 17, a second limiting plate 27, a first sliding rod 20, a plurality of second sliding rods 21, and a sliding sleeve 18. The first limiting plate 17 and the second limiting plate 27 are respectively located on both sides of the support plate 13. The first sliding rod 20 and the plurality of second sliding rods 21 are parallel to each other and slide laterally through the support plate 13, providing guidance for the overall movement of the sliding mechanism. The two ends of the first sliding rod 20 and the plurality of second sliding rods 21 are respectively fixedly connected to the second limiting plate 27 and the first limiting plate 17 to form a stable sliding frame. The sliding sleeve 18 is slidably sleeved on the outside of the first sliding rod 20 and fixedly connected to the outer side wall of the support plate 13.

[0036] It should be noted that the first limiting plate 17 and the second limiting plate 27 can be used to limit the sliding range of the first sliding rod 20 and the second sliding rod 21; the sliding sleeve 18 further improves the stability of the first sliding rod 20 when sliding and avoids deviation.

[0037] In this embodiment, the base 6 has a plurality of bolt holes 4 arranged in a ring array, which are used to fix the base 6 in place.

[0038] It should be noted that during use, the base 6 can be fixed to the experimental table by passing a bolt through the bolt hole 4 to prevent displacement during operation.

[0039] In this embodiment, the bottom of the support plate 13 and the bottom of the base 6 are located on the same horizontal plane, ensuring that the support plate 13 and the base 6 together provide stable support for the measuring instrument; the vertical bend of the support plate 13 is reinforced by multiple reinforcing blocks 12, and the reinforcing blocks 12 are fixedly connected to the horizontal and vertical sections of the support plate 13 respectively.

[0040] It should be noted that by reinforcing the connection with multiple reinforcing blocks 12, the structural strength of the bending point of the support plate 13 is improved, and the service life of the support plate 13 is extended.

[0041] Example 2 like Figure 6As shown, based on Embodiment 1, the sliding mechanism is further supplemented by including a pin 19, a first insertion hole 34, and a second insertion hole 35. The first insertion hole 34 is opened through the support plate 13 and is located above the second insertion plate 33. The first limiting plate 17 has a second insertion plate 33 on the side facing the support plate 13, and the second limiting plate 27 has a first insertion plate 22 on the side facing the support plate 13. Both the second insertion plate 33 and the first insertion plate 22 are adapted to the first insertion hole 34. The second insertion hole 35 is opened on the upper end face of the support plate 13 and is perpendicularly connected to the first insertion hole 34. After the pin 19 passes through the second insertion hole 35 from top to bottom, it is inserted into the limiting hole on the second insertion plate 33 or the first insertion plate 22.

[0042] It should be noted that when the sliding mechanism moves to the designated position, the second insert plate 33 or the first insert plate 22 can be inserted into the first insertion hole 34; and the pin 19 can be inserted into the limiting hole on the second insert plate 33 or the first insert plate 22 to fix the sliding mechanism in the designated position and prevent the sliding mechanism from moving accidentally during the experiment.

[0043] Example 3 like Figure 1 and 3 As shown, based on Embodiment 1, a further addition is made: a handle 15 is fixedly installed on the side of the first limiting plate 17 away from the support plate 13, and the gripping part of the handle 15 is covered with an anti-slip protective sleeve 16.

[0044] It should be noted that staff can push the sliding mechanism to move by holding the handle 15. The anti-slip protective cover 16 can increase the friction between the hand and the handle 15, improve the comfort of operation, and prevent the hand from slipping.

[0045] When the first limiting plate 17 contacts the side of the sliding sleeve 18, its limiting mechanism moves to the designated limiting position, which can precisely limit the truncated cone mold 23 placed on the jumping table surface 24. When the second limiting plate 27 contacts the support plate 13, the limiting mechanism is not located directly above the table surface 24 and will not come into contact with the limiting mechanism due to the jumping of the table surface 24.

[0046] Working principle: In use, first, the measuring instrument is fixed on the experimental table by passing the bolt through the bolt hole 4 on the base 6; then, the operator holds the handle 15 and pushes the sliding mechanism to move along the first slide rod 20 and the second slide rod 21, and adjusts the limiting mechanism to the appropriate position. When the second insert plate 33 or the first insert plate 22 is inserted into the first insert hole 34 on the support plate 13, the pin 19 is passed through the second insert hole 35 and inserted into the limiting hole of the second insert plate 33 or the first insert plate 22 to complete the fixing of the sliding mechanism. Next, loosen the butterfly bolt 25, rotate the two second connecting blocks 29 around the hinge point, open the second limiting ring 30, place the truncated cone mold 23 filled with cement mortar at the center of the table surface 24, then rotate the second connecting block 29 so that the two second limiting rings 30 and the first limiting ring 11 together encircle the truncated cone mold 23, tighten the butterfly bolt 25 to limit the truncated cone mold 23; Then, cement mortar is added into the truncated cone mold 23 and the corresponding treatment is carried out. After the treatment is completed, the sliding mechanism and the limiting mechanism are reversed to cancel the limiting of the truncated cone mold 23. Then, the truncated cone mold 23 is removed from the jumping table surface 24. Then, the drive motor 3 is started, which drives the transmission rod 8 and the cam 7 to rotate. The cam 7 pushes the column 2 and the table surface 24 to periodically jump through the abutment block 14. After jumping for a period of time, the cement mortar is measured according to the measurement data, thus completing this cement mortar flowability test experiment.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
