Description

Technical Field

[0001] The utility model relates to the field of concrete detection, in particular to a portable concrete setting time detection device. Background Art

[0002] Concrete is an indispensable material in construction projects, and its setting time directly affects the construction progress and project quality.

[0003] The patent with the announcement number CN207081636U discloses a concrete setting time detection device, which realizes the detection of concrete setting time by setting components such as support rods, columns, and detection parts. Among them, the columns and support rods are provided with handles that can slide up and down, and the main shaft drives the test needle to slide up and down, and the setting time is detected by detecting the change of the pressure value.

[0004] The patent with announcement number CN219179271U discloses a concrete setting time detection device, which adopts an equipment box and a concrete bucket arranged inside the detection box. A threaded rod is fixedly installed on the top of the equipment box, and a driving mechanism is connected to the threaded rod. The driving mechanism includes a motor, and a first bevel gear is fixedly installed on the output end of the motor. The first bevel gear is meshed and connected with a second bevel gear, and the second bevel gear is fixedly connected to the threaded rod. By adopting the above technical solution, when it is necessary to fit the test needle with the concrete surface in the concrete bucket, the staff can control the movement of the lifting plate through the driving mechanism, the motor can drive the first bevel gear to rotate, the first bevel gear can drive the second bevel gear to rotate, the second bevel gear can drive the threaded rod to rotate, and the lifting plate can drive the connecting rod, the mounting plate and the test needle to move, so that the test needle can quickly fit with the concrete surface in the concrete bucket.

[0005] When testing the penetration resistance value of the test mold in the same time period, 1-2 points need to be measured, and the net distance between the test needle penetrating into the mortar at each point is at least twice the diameter of the test needle used and not less than 15mm, and then the penetration resistance value of the test concrete in the time period is calculated; in addition, during the test, it should be ensured that each sample is tested for penetration resistance at least six times. Since the insertion position of the above-mentioned test needle is fixed, the above-mentioned device needs to rotate the concrete bucket during the measurement process to ensure that the test needle is inserted into the new measurement point. If the spacing adjustment cannot meet the requirements of the specification, it still needs to be adjusted repeatedly. The above-mentioned operation process is time-consuming and labor-intensive, resulting in a cumbersome measurement process and low efficiency.

[0006] In view of this, how to change the current situation that the measurement process of the existing concrete setting time detection device is cumbersome and inefficient has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Reference Figure 1-2 The utility model provides a portable concrete setting time detection device, which includes a base 1, a support frame 2, a concrete bucket 3, a lifting component, a transposition plate 4, a slider 6, a test needle 7 and a pressure display 8. Among them: the base 1 is in the shape of a racket and a plate-like structure, which is the main supporting component of the utility model; the support frame 2 and the concrete bucket 3 are arranged on the upper surface of the base 1, one end of the support frame 2 is fixedly connected to the base 1, and a lifting component and a transposition plate 4 are installed on the support frame 2. The lifting component is used to drive the transposition plate 4 to move up and down. The transposition plate 4 is arranged in the horizontal direction, and the transposition plate 4 is located above the concrete bucket 3, and the transposition plate 4 is arranged with a spiral slide 5, and a slider 6 is slidably connected in the slide 5. The slider 6 is connected to a test needle 7. The test needle 7 has a built-in pressure sensor for testing the concrete pressure value, which can measure the pressure value when the test needle 7 is inserted into the concrete. The concrete bucket 3 is used to store concrete for testing. During the concrete curing process, the concrete bucket 3 should be equipped with a barrel cover (not shown in the figure). The barrel cover can be removed to realize the insertion of the test needle 7 into the test concrete. During the movement of the slider 6 along the slide 5, the position of the test needle 7 can be adjusted. The pressure display 8 is electrically connected to the test needle 7, and the pressure display 8 can display the pressure value of the test needle 7 when it is inserted into the concrete in real time.

[0035] During use, the concrete bucket 3 stores the test concrete. When the penetration resistance value needs to be measured, the concrete bucket 3 is placed under the transposition plate 4, and the transposition plate 4 is driven down by the lifting assembly. The pressure display is used to display the pressure value when the test needle 7 is inserted into the concrete, thereby measuring the penetration resistance value of the concrete at the current test point. The transposition plate 4 is driven up by the lifting assembly to complete the measurement process of the current measurement point. When the measurement point needs to be changed, the position of the test needle 7 can be changed by sliding the slider 6 on the slide 5 without rotating the concrete bucket 3, and the distance between the position of the test needle 7 after the change and the original position should be guaranteed to meet the test specifications. The transposition plate 4 is driven down and up by the lifting assembly again, and the penetration resistance value of the measurement point after the position is changed can be measured. The above operation is repeated to detect the change of the pressure value to achieve the detection of the setting time.

[0036] The test needle 7 in the utility model can change its position as the slider 6 slides in the slide groove 5. When multiple measuring points need to be measured, the measuring needle can be inserted into a new measuring point without rotating the concrete bucket 3, thereby avoiding repeated adjustments when the position between the concrete bucket 3 and the measuring needle does not meet the specifications. The position adjustment process of the test needle 7 is simpler and easier to operate, thereby improving the measurement efficiency.

[0037] In the utility model, the lifting assembly includes a lifting rod 9 that can move up and down. The lifting rod 9 is cylindrical. The lower end of the lifting rod 9 is vertically fixedly connected to the transposition plate 4. During the rising and falling process of the lifting plate, the transposition plate 4 can be driven to rise and fall synchronously.

[0039] When in use, the staff can hold the other end of the sliding rod 11 and then rotate it around the lifting rod 9 to achieve the sliding process of the slider 6 in the sliding groove 5, thereby achieving the effect of adjusting the position of the test needle 7. In order to facilitate the operation of the sliding rod 11 and facilitate the staff to hold the sliding rod 11, the other end of the sliding rod 11 is provided with an end head 12, and the cross-sectional area of ​​the end head 12 is larger than the cross-sectional area of ​​the sliding rod 11. The staff can operate the sliding rod 11 by holding the end head 12.

[0040] Preferably, the sliding rod 11 and the cross rod are arranged in parallel, and both the sliding rod 11 and the cross rod are located in the radial direction of the lifting rod 9 .

[0041] For ease of operation, refer to Figure 3-4 The chute 5 is also provided with a smooth connection section 13, which is Figure 4 In the area surrounded by the dotted line, the starting end of the outermost circle of the slide groove 5 is connected to the terminal end of the innermost circle of the slide groove 5 through a smooth connecting section 13. The cross section of the slider 6 along the horizontal direction is a rounded diamond shape, and the length of the slider 6 along the sliding direction of the slide groove 5 is greater than the distance between adjacent slide grooves 5 along the radial direction. When in use, the slider 6 is first placed at the starting end of the outermost circle of the slide groove 5, and then the sliding rod 11 is rotated in a single direction to make the slider 6 slide along the slide groove 5. Figure 4 The process of adjusting the position of the test needle 7 is achieved by rotating the slider 6 in the counterclockwise direction. When the slider 6 slides to the end of the innermost circle of the slide groove 5, the sliding rod 11 is rotated again to enable the slider 6 to return to the starting end of the outermost circle of the slide groove 5 through the smooth connecting section 13, without the need to restore the slider 6 to its initial position by reverse rotation, which makes the use process simpler.

[0042] It should be noted that the test needle 7 of the present invention is preferably connected to one end of the sliding rod 11 by rotation, so as to avoid the wire connected to the test needle 7 from being entangled.

[0043] Refer again Figure 1-2 The lifting assembly also includes a driving gear 14 and a rack 15. The support frame 2 is in a "7" shape, one end of the support frame 2 is fixedly connected to the base 1, and the other end of the support frame 2 is rotatably connected to the driving gear 14; the upper side wall of the lifting rod 9 is fixedly connected to the rack 15, the lifting rod 9 and the rack 15 slide in the vertical direction through the other end of the support frame 2, and the rack 15 is meshed with the driving gear 14. By rotating the driving gear 14, the rising and falling process of the rack 15 and the lifting rod 9 can be realized.

[0044] In order to facilitate the operation of the driving gear 14, the utility model further comprises a handle 17, one end of which is coaxially fixedly connected to the driving gear 14. By rotating the handle 17, the driving gear 14 can be driven to rotate.

[0045] A damping rubber 16 is embedded in the other end of the support frame 2, and the damping rubber 16 is frictionally connected with the outer wall of the upper end of the lifting rod 9 in the vertical direction.
