Description

Technical Field

[0001] The present invention relates to the field of concrete detection, and particularly to a detection device for ultra-high performance concrete. Background Art

[0002] It is well-known that ultra-high performance concrete (referred to as UHPC) has characteristics such as high durability and high strength, and is particularly suitable for engineering scenarios with high durability, light weight, and complex shapes. With the decline in cost and the improvement of standards, its application prospects in the fields of infrastructure, green buildings, national defense, etc. are broad. When detecting it, items such as compressive strength, slump, and spread are included.

[0003] For example, in a Chinese patent document with the authorization announcement number CN213068863U, the announcement date of April 27, 2021, and the name of "A Concrete Slump Meter", it includes a bottom plate which is horizontally arranged. A slump cone is arranged on the bottom plate, and the slump cone is located at the center of the bottom plate. One end of the slump cone in contact with the bottom plate extends horizontally outwards with a fixing plate. An elastic member is wound around the circumference of the slump cone, and one end of the elastic member away from the fixing plate is provided with a foot ring, and the axis of the foot ring is coaxially arranged with the axis of the slump cone; a leveling member is arranged at the upper end of the slump cone, and the concrete at the upper end of the slump cone is leveled by the leveling member. This application helps to improve the tightness between the slump cone and the bottom plate, prevent the concrete in the slump cone from flowing out from the gap between the slump cone and the bottom plate, and thus improve the qualified rate of the test.

[0004] The disadvantages of the above prior art are that when loading concrete into the slump cone, a funnel is placed on the top of the slump cone, and then a shovel is used to shovel the concrete into the funnel. In case of lack of conditions, even a shovel is used to load the concrete. Moreover, after each 1 / 3 loading, it is necessary to ram 25 times. Since the funnel has no fixing device, it is very easy for the funnel to fall off the slump cone, thus affecting the detection process. Summary of the Invention

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0021] In the description of the present invention, it should be understood that taking Figure 3 the position of the hopper 2 relative to the slump cone 1 as up, and vice versa as down, the terms "center", "length", "width", "degree", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0022] Referring to Figures 1-10 , a super high performance concrete testing device provided by an embodiment of the present invention includes a slump cone 1 and a hopper 2 provided on the slump cone 1, and a fixing component for fixing the position of the hopper 2 is provided on the slump cone 1; When filling concrete into the slump cone 1, the fixing component limits the hopper 2, and when removing the hopper 2 from the slump cone 1, the fixing component levels the top of the slump cone 1.

[0023] Specifically, slump is a method and index for determining the workability of concrete. On construction sites and in laboratories, a slump test is usually performed to determine the fluidity of the mixture. The slump cone 1 is a truncated cone-shaped cylindrical structure. During the test, a funnel 2 is placed on the top of the slump cone 1, and the concrete is shoveled into the funnel 2 and slides into the slump cone 1. After each 1 / 3 of the concrete is filled, the tamping rod is used to tamp 25 times until the filling is completed. Then the funnel 2 is removed, and the excess concrete on the top of the slump cone 1 is scraped off by a scraper and other components. Then, the slump cone 1 is completely lifted up in a short time. At this time, the concrete remains at the bottom and collapses. Then, the difference between the height of the slump cone 1 and the highest point of the collapsed concrete is measured, which is the slump value. This is the prior art. Without going into details, one of the core innovations of the embodiment of the present invention is that a fixing component is added to the slump cone 1. The fixing component can be two symmetrically arranged clamping plates, and the clamping plates are at the same height as the top of the slump cone 1. The power for its reciprocating movement can be provided by an existing reciprocating drive component such as an electric push rod. The purpose of such a setting is that when concrete is loaded into the slump cone 1, the clamping plates abut against the outer peripheral surface of the funnel 2 to limit the funnel 2, thereby minimizing the funnel 2 from falling off the slump cone 1 during the concrete loading process; and when the funnel 2 is removed from the slump cone 1, the top of the slump cone 1 can be smoothed by controlling the reciprocating movement of the clamping plates, thereby speeding up the process of concrete testing.

[0024] Preferably, the fixing assembly includes a first smoothing rod 3, a first rotating seat 4 is fixedly connected to the slump cone 1, a first torsion spring (not shown) is arranged between the first smoothing rod 3 and the first rotating seat 4, and an abutment ring 5 is arranged on the funnel 2, and the first smoothing rod 3 abuts against the abutment ring 5. Specifically, the first rotating seat 4 is fixedly connected to the outer peripheral surface of the slump cone 1, a rotating hole is opened on the first rotating seat 4, a rotating shaft is arranged on the first smoothing rod 3, the rotating shaft is rotatably connected with the rotating hole, and a first torsion spring is arranged between the rotating hole and the rotating shaft. When the first smoothing rod 3 abuts against the abutment ring 5, the elastic force of the first torsion spring makes the first smoothing rod 3 have a tendency to rotate toward the central axis direction of the slump cone 1. The abutment ring 5 is fixedly connected to the outer peripheral surface of the funnel 2. When the funnel 2 is placed on the top of the slump cone 1, the abutment ring 5 is located outside the slump cone 1, and the upper and lower surfaces of the abutment ring 5 are provided with inclined surfaces. The effect of such a setting is that, Figure 2As shown, when placing the funnel 2, one hand holds the funnel 2, and the other hand rotates the first smoothing rod 3 clockwise, and accumulates force on the first torsion spring to make the first smoothing rod 3 move away from the slump cone 1. When the funnel 2 is placed, that is, a part of the bottom end of the funnel 2 is inserted into the slump cone 1, the first smoothing rod 3 is released at this time, and the first smoothing rod 3 rotates counterclockwise under the elastic force of the first torsion spring, and abuts with the inclined surface above the abutment ring 5, so that under the action of the first torsion spring, the abutment ring 5 provides a downward force, so that the funnel 2 can be prevented from falling from the slump cone 1 as much as possible to achieve a flexible fixing effect. When the concrete is filled, the funnel 2 is directly lifted up. At this time, under the action of the abutment of the inclined surface of the abutment ring 5 and the first smoothing rod 3, the first smoothing rod 3 rotates clockwise again to achieve avoidance, thereby facilitating the removal of the funnel 2.

[0025] Preferably, the lower surface of the first smoothing rod 3 is at the same vertical height as the upper surface of the slump cone 1. Specifically, when the first smoothing rod 3 is not limited, the elastic force of the first torsion spring makes the first smoothing rod 3 on the other side of the slump cone 1, that is, on the opposite side when the first smoothing rod 3 fixes the funnel 2. The effect of such a setting is that when the concrete is filled, the funnel 2 is removed from the slump cone 1. At this time, the elastic force of the first torsion spring is released, thereby driving the first smoothing rod 3 to rotate counterclockwise. Since the elastic force of the first torsion spring makes the first smoothing rod 3 on the other side of the slump cone 1, the first smoothing rod 3 will slide over the upper surface of the slump cone 1, so that the first smoothing rod 3 has an additional effect, that is, the effect of scraping the top of the slump cone 1.

[0026] It should be noted that when too much concrete overflows from the top of the slump cone 1, relying solely on the single movement of the first leveling rod 3, the leveling effect of the slump cone 1 cannot reach the expected level. Further, the fixing assembly further includes a second leveling rod 6. A second rotating seat 7 is fixedly connected to the slump cone 1. A second torsion spring (not shown) is provided between the second leveling rod 6 and the second rotating seat 7. The second leveling rod 6 abuts against the abutting ring 5; a limiting member for restricting the position of the second leveling rod 6 is further included. Specifically, the second rotating seat 7 and the first rotating seat 4 are arranged symmetrically about the axis of the slump cone 1. The second leveling rod 6 and the first leveling rod 3 are arranged centrosymmetrically about the center of the slump cone 1. A rotating hole is also provided on the second rotating seat 7, and a rotating shaft is also provided on the second leveling rod 6. The second torsion spring is arranged between the rotating hole and the rotating shaft. When the second leveling rod 6 abuts against the abutting ring 5, and the elastic force of the second torsion spring causes the second leveling rod 6 to tend to rotate towards the central axis direction of the slump cone 1. And since the top of the slump cone 1 has been leveled once by the first leveling rod 3, only a small amount of unleveled concrete remains on the top of the slump cone 1. Therefore, the thickness of the second leveling rod 6 is less than the thickness of the first leveling rod 3, and the elastic force of the second torsion spring is less than the elastic force of the first torsion spring. The limiting member can be a blocking structure on the movement stroke of the second leveling rod 6. The function of such a setting is that when the funnel 2 is not placed on the top of the slump cone 1, the second leveling rod 6 abuts against the limiting member under the elastic force of the second torsion spring. And at this time, the second leveling rod 6 is on the descending stroke of the funnel 2. During the installation of the funnel 2, the inclined surface below the abutting ring 5 will abut against the second leveling rod 6, thereby driving the second leveling rod 6 to rotate clockwise to achieve avoidance. When the abutting ring 5 abuts against the second leveling rod 6, the elastic force of the second torsion spring is released, driving the second leveling rod 6 to rotate counterclockwise so that the second leveling rod 6 abuts against the inclined surface above the abutting ring 5, and the clockwise rotation angle is greater than the counterclockwise rotation angle. Therefore, at this time, the second leveling rod 6 will only abut against the abutting ring 5 and will not abut against the limiting member (as shown in Figure 4 ), so the second leveling rod 6 will also provide a downward acting force on the abutting ring 5 to improve the fixing effect of the funnel 2. When the funnel 2 is removed, a part of the elastic force of the second torsion spring will be released first so that the second leveling rod 6 abuts against the limiting member (as shown in Figure 5 ), after the first leveling rod 3 levels the slump cone 1 once, the limiting effect of the limiting member on the second leveling rod 6 is released, so that the elastic force of the second torsion spring is further released to drive the second leveling rod 6 to level the top of the slump cone 1 for the second time.

[0027] After the concrete is leveled for the first time, there is a probability of pits appearing, which will affect the leveling effect of the slump cone 1. To solve the above problems, preferably, a plurality of protrusions 8 are provided on the second leveling rod 6. Specifically, the cross-section of the protrusion 8 is a triangular structure, and a plurality of them are evenly arranged on the surface of the second leveling rod 6 close to the central axis of the slump cone 1. The function of this setting is that when the second leveling rod 6 rotates to perform secondary leveling on the slump cone 1, it will drive the plurality of protrusions 8 to move synchronously, so that the inclined surface of the protrusion 8 abuts against the excess concrete, so as to squeeze the area with more concrete to both sides, so as to increase the coverage area of the concrete, so as to facilitate filling the pits, so as to perform fine leveling.

[0028] Preferably, the limiting member includes a limiting rod 9. A third rotating seat 10 is fixedly connected to the slump cone 1. The limiting rod 9 is rotatably arranged on the third rotating seat 10, and a third torsion spring is arranged between the limiting rod 9 and the third rotating seat 10. The limiting rod 9 is located on the movement stroke of the first leveling rod 3. Specifically, a groove 11 is provided at the top of the third rotating seat 10. The bottom end of the limiting rod 9 is rotatably connected to the side wall of the third rotating seat 10, and a third torsion spring (not shown) is arranged between the limiting rod 9 and the third rotating seat 10. The elastic force of the third torsion spring makes the limiting rod 9 abut against one side wall of the groove 11. The function of this setting is that after the funnel 2 is removed, the elastic force of the first torsion spring is released, which will drive the first leveling rod 3 to perform primary leveling on the slump cone 1. The elastic force of the second torsion spring makes the second leveling rod 6 abut against the limiting rod 9 (as Figure 6 shown). During the movement of the first leveling rod 3, it will abut against the limiting rod 9, so as to drive the limiting rod 9 to rotate downward, so as to passively release its limiting effect on the second leveling rod 6. At this time, the second leveling rod 6 will rotate counterclockwise above the limiting rod 9 (as Figure 7 shown), so as to prevent the limiting rod 9 from rotating in the reverse direction (at this time, the second leveling rod 6 will abut against the first leveling rod 3. Since the elastic force of the second torsion spring is less than the elastic force of the first torsion spring, and at this time the first leveling rod 3 has rotated past the perpendicular bisector position of the first leveling rod 3, the first leveling rod 3 will not be blocked by the second leveling rod 6). When the first leveling rod 3 and the second leveling rod 6 are far apart, the elastic force of the second torsion spring is released to provide the power required for secondary leveling.

[0029] Furthermore, two handles 12 are symmetrically arranged on the slump cone 1. The two handles 12 are used to provide two force application points to facilitate lifting the slump cone 1.

[0030] When manually lifting the slump cone 1, it is easy to cause the slump cone 1 to tilt, which may easily lead to the collapse of the concrete, thus affecting the test results of the concrete slump. Further, it also includes a bottom plate 13, and a guiding component for improving the stability of the slump cone 1 is arranged between the bottom plate 13 and the slump cone 1. The guiding component includes a guiding rod 14, and a connecting rod 15 is fixedly connected to the slump cone 1. The connecting rod 15 is slidably connected to the guiding rod 14. Specifically, the bottom plate 13 is preferably a square plate, and preferably two guiding rods 14 are provided. The two guiding rods 14 are symmetrically arranged above the bottom plate 13. Similarly, preferably two connecting rods 15 are provided. The two connecting rods 15 are horizontal and arranged corresponding to the positions of the two guiding rods 14. A guiding hole adapted to the guiding rod 14 is formed in the connecting rod 15. The function of such a setting is that when it is necessary to lift the slump cone 1 after the concrete is filled, an upward acting force is applied to the slump cone 1 through the handle 12. Under the action of the guiding rod 14, the slump cone 1 can be moved vertically upward, so as to improve the stability of the slump cone 1 during lifting, thereby minimizing the concrete collapse caused by the tilt of the slump cone 1 and improving the accuracy of the concrete test. Moreover, under the action of the sliding connection between the guiding rod 14 and the connecting rod 15, the horizontal direction of the slump cone 1 can be limited to improve the stability during concrete filling.

[0031] It should be noted that when filling the slump cone 1 with concrete, since there is no limit in the vertical direction of the slump cone 1, it is easy to generate a gap between the bottom end of the slump cone 1 and the bottom plate 13, so that the concrete is likely to flow out from the gap. Further, a sliding seat 16 is arranged on the connecting rod 15, and a locking rod 17 is slidably arranged on the sliding seat 16. A locking groove 18 adapted to the locking rod 17 is formed in the guiding rod 14. When the funnel 2 is located on the slump cone 1, the locking rod 17 is inserted into the locking groove 18. After the funnel 2 is separated from the slump cone 1, the locking rod 17 is separated from the locking groove 18. Specifically, the sliding seat 16 is arranged on the upper surface of the connecting rod 15, and a sliding groove 19 is arranged inside it. The locking rod 17 is slidably connected to the sliding groove 19. The function of such a setting is that when the funnel 2 is located on the slump cone 1, that is, when the concrete has not been completely filled yet, at this time, the locking rod 17 is controlled to be inserted into the locking groove 18 through a reciprocating driving component such as an electric push rod, so as to limit the vertical direction of components such as the connecting rod 15 and the slump cone 1, thereby improving the stability during concrete filling. After the concrete is filled, the locking rod 17 is controlled to be withdrawn from the locking groove 18 to realize the active unlocking of the slump cone 1.

[0032] As an alternative to the above-described electric push rod for controlling the reciprocating movement of the locking rod 17, preferably, a connecting rope 20 is provided between the locking rod 17 and the first leveling rod 3, and a spring 21 is provided between the locking rod 17 and the sliding seat 16. Specifically, the connecting rope 20 is preferably a metal rope with low ductility. One end of the connecting rope 20 is fixedly connected to the rotating shaft of the first leveling rod 3, and the other end passes through the side wall of the sliding seat 16 and is fixedly connected to the locking rod 17. One end of the spring 21 is fixedly connected to the side wall of the chute 19, and the other end is fixedly connected to the locking rod 17. And semi-circular limiting rings 22 are provided on the slump cone 1, the two rotating seats and the connecting rod 15, which are used to limit the position of the connecting rope 20. The purpose of such a setting is that after the funnel 2 is removed after the concrete is filled, the first leveling rod 3 will rotate, and the rotating shaft will rotate synchronously, so that the connecting rope 20 is wound around the rotating shaft and the connecting rope 20 is pulled, so that the connecting rope 20 pulls the locking rod 17 to slide into the interior of the chute 19 and stores energy in the spring 21, so that the locking rod 17 is passively withdrawn from the locking groove 18, so that the connecting rod 15 and the slump cone 1 are passively unlocked. After a single slump measurement is completed, the concrete on the bottom plate 13 and the slump cone 1 is cleaned up, and the guiding hole is sleeved on the guiding rod 14 again to complete the installation of the slump cone 1. Repeat the above steps to measure the slump value for the second time, and take the average value of the two measured slump values as the final slump value.

[0033] It should be noted that there are two locking rods 17. Correspondingly, there are also two sliding seats 16, springs 21 and locking grooves 18, which are symmetrically arranged with respect to the slump cone 1. And a connecting rope 20 is also provided between the second leveling rod 6 and the other locking rod 17. During the rotation of the second leveling rod 6, the locking rod 17 and the locking groove 18 will also be unlocked.

[0034] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
