Description

Technical Field

[0001] The utility model relates to the technical field of concrete parameter measuring equipment, in particular to a concrete slump measuring instrument. Background Art

[0002] In the process of construction, concrete is inevitably used. Concrete has a series of advantages such as high hardness, good mechanical properties, and low cost. However, before a batch of concrete is used in a building, the slump of the concrete needs to be measured to ensure that the concrete meets national standards. Therefore, a concrete slump measuring instrument is needed to test the slump of the concrete.

[0003] Chinese patent CN207717768U discloses a rapid concrete slump measuring instrument, which includes a slump cone, a vibrator for vibrating the concrete in the slump cone, a workbench, a steel rope, a driving device for driving the steel rope, and a support frame; the workbench includes a bottom plate and side plates, which are connected to each other; the slump cone is placed on the bottom plate, and the side plates are provided with scale lines and scale readings; two symmetrical hanging ears are provided on both sides of the slump cone, one end of the steel rope is connected to the hanging ear, and the other end of the steel rope is connected to the driving device, which is fixed to the support frame, and the vibrator is fixed to the support frame, and the slump cone is located directly below the vibrator; it has the advantages of simple operation, fast and accurate measurement of concrete slump. However, there are still defects that can be improved:

[0004] 1. This utility model uses steel ropes to drive the slump cone up or down. However, it should be noted that the steel ropes are flexible and only two of them are hung on the slump cone's lugs. Furthermore, the guide column is relatively short. This means that after the slump cone is raised to a certain height by the steel ropes, the bottom of the cone will shake, affecting the concrete inside the cone and ultimately leading to inaccurate data measurements.

[0005] 2. The fixed plate of the utility model is fixedly connected to the support frame, which will cause the vibrator to interfere with the slump cone, making it impossible to add concrete into the slump cone smoothly. Moreover, when the slump cone rises, it interferes with the vibrator, causing the slump cone to not rise to the top, resulting in the user's measurement data being affected by the slump cone.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0036] The present invention will be described in further detail below with reference to the accompanying drawings.

[0037] The working principle of this utility model is as follows Figures 1-6 As shown, a concrete slump measuring instrument includes a base 1. First, a measuring plate 7 is fixedly connected to the middle of the rear side of the top of the base 1. A measuring scale is set on one side of the front end of the measuring plate 7. At the same time, a sliding groove 8 is opened in the middle of the front end of the measuring plate 7, and a connecting block 9 is slidably connected in the sliding groove 8. Then, a telescopic measuring ruler 10 is fixedly connected to the front end of the connecting block 9. The telescopic measuring ruler 10 is used in conjunction with the scale on the measuring plate 7. The effect achieved so far is that when measurement is required, the user first moves the connecting block 9 to a specified height, and then the connecting block 9 will drive the telescopic measuring ruler 10 to the specified position. Then the user can read the scale where the telescopic measuring ruler 10 is located, and then the user moves the connecting block 9 to the middle of the top of the base 1. A slump cone 4 is provided. It is worth mentioning that threaded through holes 5 are opened on the hanging ears on both sides of the slump cone 4, and then a lifting device 6 is provided in the middle of both sides of the top of the base 1. It should be noted that the lifting device 6 is used in conjunction with the slump cone 4, and then a groove 2 is opened in the middle of the front side of the top of the base 1, and an adjusting device 3 is provided in the groove 2. At the same time, a vibration motor 12 is provided above the groove 2, and a connecting rod 13 is fixedly connected to the output shaft at the bottom end of the vibration motor 12, and finally, a vibration block 14 is fixedly connected to the bottom end of the connecting rod 13. The effect achieved so far is that when the vibration motor 12 is turned on, the connecting rod 13 fixedly connected to the vibration motor 12 will drive the vibration block 14 to move up and down.

[0038] The above-mentioned structures together constitute the general appearance structure of the concrete slump measuring instrument of the present invention.

[0039] In order to further explain the specific working principle of a concrete slump measuring instrument of the present invention, the adjusting device 3 includes a sliding plate 301 slidably connected to the groove 2. First, a coupling block 303 is provided above the sliding plate 301, and the bottom end of the coupling block 303 is fixedly connected to the telescopic column 302. It is worth noting that the telescopic column 302 has a self-locking function. Then the bottom end of the telescopic column 302 is fixedly connected to the sliding plate 301. At the same time, the rear end of the coupling block 303 is fixedly connected to the bracket 11. Then the vibration motor 12 is set on the bracket 11. The effect achieved so far is that by adjusting the length of the telescopic column 302, the telescopic column 302 can drive the vibration motor 12 to rise and fall. Then, fixed blocks 304 are fixedly connected to the middle of both sides of the top of the sliding plate 301, and the tops of the fixed blocks 304 on both sides are fixedly connected to limited The cam 308 is fixed to the top of the cam 309 and the bottom of the cam 309 is fixed to the top of the cam 309. When the cam 308 is lifted up, the cam 308 will pull the spring 309 and the cam 307 will move upwards. Then, a plurality of fixing holes 310 are opened on both sides of the front top of the base 1. The plurality of fixing holes 310 are arranged longitudinally, and the positioning shaft 307 is used in conjunction with the fixing holes 310.

[0040] The technical effect achieved by the technical solution composed of the above technical features is: when stationary, the positioning shaft 307 is inserted into the fixing hole 310, so that the position of the sliding plate 301 in the groove 2 remains stationary, so that the vibration motor 12 can stably drive the connecting rod 13 and the shock block 14 to operate together; when the position of the vibration motor 12 needs to be adjusted, the length of the telescopic column 302 is first adjusted to make the vibration motor 12 rise, and then the user lifts the positioning blocks 308 on both sides upwards, and the positioning blocks 308 move upwards. The positioning block 308 will drive the positioning shaft 307 to move upward, and the positioning block 308 will also stretch the spring 309 upward. When the positioning shaft 307 is completely removed from the fixing hole 310, the sliding plate 301 can move in the groove 2, and then move the sliding plate 301 to the specified position. The user releases the positioning blocks 308 on both sides, and the spring 309 will reset the positioning blocks 308. Then the positioning blocks 308 on both sides will push the positioning shaft 307 into the next fixing hole 310, and re-fix the sliding plate 301.

[0041] In order to further explain the specific working principle of a concrete slump measuring instrument of the present invention, the above-mentioned lifting device 6 includes a fixed box 601 fixedly connected to the middle part of one side of the top of the base 1, and then a receiving block 603 is slidably connected in the fixed box 601, and the bottom end of the receiving block 603 is fixedly connected to a hydraulic telescopic cylinder 602, where the bottom end of the hydraulic telescopic cylinder 602 is fixedly connected to the bottom wall of the fixed box 601, and the hydraulic telescopic cylinder 602 can push the receiving block 603 to a specified height, and then a receiving plate 605 is fixedly connected to the lower part of the receiving block 603 near the slump cylinder 4. When the receiving block 603 rises, the receiving plate 605 is fixedly connected to the receiving block 603. The connecting plate 605 can drive the slump cylinder 4 to rise together. At the same time, a threaded plate 604 is provided above the connecting plate 605, and the side of the threaded plate 604 away from the slump cylinder 4 is fixedly connected to the connecting block 603, and a screw rod 606 is threadedly connected to the threaded plate 604. Here, the screw rod 606 and the threaded through hole 5 are used in conjunction. When the screw rod 606 and the threaded through hole 5 are threadedly connected, the screw rod 606 can fix the slump cylinder 4. Finally, a rotating handle 607 with locking ability is fixedly connected to the top of the screw rod 606. When the user stops rotating the rotating handle 607, the rotating handle 607 will not rotate by itself.

[0042] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: first, turn the handle 607 to rotate, driving the screw rod 606 to rotate. At this time, the screw rod 606 will rotate and move downward until the screw rod 606 and the threaded through hole 5 are threadedly connected. The screw rod 606 limits the displacement of the slump cylinder 4. Then the hydraulic telescopic cylinders 602 on both sides push their own working rods upward. In this process, the hydraulic telescopic cylinders 602 will push the receiving block 603 to move upward, and the receiving plate 605 fixedly connected to the receiving block 603 will drive the slump cylinder 4 to move upward together.
