Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically a concrete setting time statistical device. Background Technology

[0002] One of the tests for concrete is its setting time. In practice, the concrete is first mixed and then transferred to a testing device to determine its setting time. However, current testing devices generally have the following problems:

[0003] 1. Traditional equipment can only test setting time at a single location and cannot monitor multiple locations simultaneously. This makes it impossible to fully understand the setting process of concrete or mortar and to detect differences between different parts in a timely manner.

[0004] 2. The sample container of current testing equipment is generally a single piece. After the testing is completed, the concrete sets, making demolding difficult, time-consuming, and labor-intensive for operators, thus reducing testing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a concrete setting time statistical device, which solves the problem that traditional equipment can only test the setting time at a single location and cannot monitor multiple locations simultaneously. It also solves the problem that after the concrete sets, it is inconvenient to demold.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete setting time statistical device, comprising a platform, a turntable placed in the middle of the platform, several movable wheels equidistantly connected to the sides of the turntable, a demolding assembly mounted on the turntable, a detection box mounted on the demolding assembly, support columns symmetrically arranged at both ends of the platform, a bearing plate fixed on the two support columns, an electric actuator mounted on the bearing plate, the output end of the electric actuator facing downwards, and the output end of the electric actuator passing through the bearing plate and equipped with a data acquisition device.

[0007] Preferably, the demolding assembly includes a base fixedly connected to the upper end of the turntable, a groove is provided on the base along the length direction, a bidirectional lead screw is rotatably connected to the groove, and movable blocks are symmetrically threaded at the positive and negative threads of the bidirectional lead screw. The detection box is divided into a left half box and a right half box, and the left half box and the right half box are respectively fixed on the two movable blocks.

[0008] Using the above design scheme, before testing, the two movable blocks are brought closer together by rotating the bidirectional screw, and the left and right halves of the box are tightly fitted to form the testing box structure. Concrete can then be injected into the testing box for testing. After testing, the bidirectional screw is rotated in the opposite direction to move the left and right halves of the box away from each other, thus completing the demolding operation. The demolding and demolding of this testing box are relatively simple, which greatly saves the time required for demolding and demolding, reduces the labor intensity of operators, and achieves the effect of improving testing efficiency.

[0009] Preferably, the support plate has a movable groove along its length, a movable plate is placed on the support plate, the electric actuator is fixed on the movable plate, and the output end of the electric actuator passes through the movable plate and the movable groove.

[0010] Preferably, the support plate has several positioning holes equidistantly spaced along its length, and the positioning bolts pass through the movable plate and are threadedly connected to the positioning holes.

[0011] By adopting the above structural design, and through the coordinated use of the movable plate, movable groove, positioning hole, and positioning bolt, the lateral position of the electric actuator and the data acquisition unit can be easily adjusted. Combined with the rotation of the detection box by the turntable, the data acquisition unit can detect concrete at different locations inside the detection box, thereby improving the accuracy of its detection.

[0012] Preferably, the movable block has a fixing hole on its side end, and the left half box and the right half box have threaded holes on their side ends relative to the fixing hole. The bolt passes through the fixing hole and is threadedly connected to the threaded hole.

[0013] The above structural design, through the use of fixing holes, threaded holes, and bolts, facilitates the replacement of testing boxes of different sizes, thus improving the applicability of the device.

[0014] Preferably, the left half of the box has a slot on one side relative to the right half of the box, and the right half of the box has a strip on one side relative to the left half of the box that mates with the slot.

[0015] By adopting the above structural design and setting slots and inserts, the left and right halves of the test box are more tightly connected, preventing concrete from seeping out of the test box during the testing process.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By using a combination of a movable plate, a movable slot, positioning holes, and positioning bolts, the lateral position of the electric actuator and the data acquisition unit can be easily adjusted. Combined with the rotation of the test box by the turntable, the data acquisition unit can detect concrete at different locations inside the test box, thereby improving the accuracy of the detection.

[0018] 2. Before conducting the testing, the two movable blocks are brought closer together by rotating the double-acting screw, and the left and right halves of the box are tightly fitted to form the testing box structure. Concrete can then be injected into the testing box for testing. After the testing is completed, the double-acting screw is rotated in the opposite direction to move the left and right halves of the box away from each other, thus completing the demolding operation. The demolding and demolding of this testing box are relatively simple, which greatly saves the time required for demolding and demolding, reduces the labor intensity of operators, and achieves the effect of improving testing efficiency.

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.

[0025] Please see Figures 1 to 5This utility model provides a technical solution: a concrete setting time statistics device, including a platform 1, a turntable 8 placed in the middle of the platform 1, four equidistant moving wheels 9 rotatably connected to the sides of the turntable 8, a demolding assembly 6 installed on the turntable 8, a detection box 7 set on the demolding assembly 6, support columns 2 symmetrically arranged at both ends of the platform 1, a bearing plate 3 fixed on the two support columns 2, an electric actuator 4 set on the bearing plate 3, the output end of the electric actuator 4 facing downwards, and the output end of the electric actuator 4 passing through the bearing plate 3 and set with a data acquisition device 5. The electric actuator 4 can drive the data acquisition device 5 to move downwards and contact the concrete in the detection box 7, thereby detecting the concrete. A drive motor 10 is set inside the middle of the platform 1. The output end of the drive motor 10 extends out of the platform 1 and is fixed at the center of the turntable 8. The turntable 8 is driven to rotate by the drive motor 10. Four movable wheels 9 are provided on the side of the turntable 8 to make the rotation of the turntable 8 smoother. The platform 1 has a circular groove that matches the size of the turntable 8, and the movable wheels 9 are located in the circular groove.

[0026] The demolding assembly 6 includes a base 601 fixedly connected to the upper end of the turntable 8. A groove 603 is provided on the base 601 along its length. A bidirectional lead screw 604 is rotatably connected to the groove 603. Movable blocks 602 are symmetrically threaded at the positive and negative threads of the bidirectional lead screw 604. The detection box 7 is divided into a left half box 701 and a right half box 702. The left half box 701 and the right half box 702 are respectively fixed on the two movable blocks 602. A rotating motor 15 is installed at one end of the bidirectional lead screw 604. Before the testing work, the rotating motor 15 drives the bidirectional lead screw 604 to rotate, so that the two movable blocks 602 move closer to each other, and the left half box 701 and the right half box 702 fit tightly together to form the structure of the testing box 7. Concrete can then be injected into the testing box 7 for testing. After the testing is completed, the bidirectional lead screw 604 is rotated in the opposite direction, so that the left half box 701 and the right half box 702 move away from each other, thereby completing the demolding operation. The demolding and demolding of this testing box 7 are relatively simple, which greatly saves the time required for demolding and demolding, reduces the labor intensity of operators, and achieves the effect of improving testing efficiency.

[0027] The support plate 3 has a movable groove 18 along its length, and a movable plate 16 is placed on the support plate 3. The electric actuator 4 is fixed on the movable plate 16, and the output end of the electric actuator 4 passes through the movable plate 16 and the movable groove 18. By using the movable plate 16, the movable groove 18, the positioning hole 19, and the positioning bolt 17 in combination, the lateral position of the electric actuator 4 and the data acquisition device 5 can be easily adjusted.

[0028] The support plate 3 has several positioning holes 19 evenly spaced along its length. The positioning holes 19 are arranged in two rows symmetrically about the movable groove 19. The positioning bolts 17 pass through the movable plate 16 and are threadedly connected to the positioning holes 19. The positioning bolts 17 fix the positions of the movable plate 16 and the electric push rod 4, improving the stability of the device during testing.

[0029] The movable block 602 has a fixing hole 13 on its side end. The left half box 701 and the right half box 702 have threaded holes 14 on their side ends relative to the fixing hole 13. Bolts pass through the fixing hole 13 and are threadedly connected to the threaded hole 14. There are two symmetrically arranged threaded holes 14, and the threaded holes 14 do not penetrate the side wall of the detection box 7.

[0030] The left half-box 701 has a slot 11 on one side relative to the right half-box 702, and the right half-box 702 has an insert 12 on one side relative to the left half-box 701 that cooperates with the slot 11.

[0031] Working Principle: Before testing, the motor 15 drives the bidirectional lead screw 604 to rotate, bringing the two movable blocks 602 closer together. The left half-box 701 and the right half-box 702 fit tightly together to form the testing box 7 structure, allowing concrete to be injected into the testing box 7. The electric actuator 4 moves the data acquisition device 5 downwards to contact the concrete inside the testing box 7, thus enabling concrete testing. The use of the movable plate 16, movable groove 18, positioning hole 19, and positioning bolt 17 facilitates the adjustment of the lateral position of the electric actuator 4 and the data acquisition device 5. Combined with the rotation of the testing box 7 by the turntable 8, the data acquisition device 5 can test the concrete at different locations inside the testing box 7, improving the accuracy of the testing. After the test is completed, rotate the double-acting screw 604 in the opposite direction to move the left half box 701 and the right half box 702 away from each other, thereby completing the demolding operation. The mold closing and demolding operations of this test box 7 are relatively simple, which greatly saves the time required for mold closing and demolding, reduces the labor intensity of operators, and achieves the effect of improving test efficiency.
