Description

Technical Field

[0001] The utility model relates to the technical field of building material quality detection, in particular to a mortar consistency measuring device. Background Art

[0002] The complex construction environment of remote tunnels places particularly stringent demands on material quality. Mortar, a key material for tunnel linings, supports, and other structures, has a direct impact on construction quality and structural stability. Therefore, using a mortar consistency meter to accurately measure and control mortar consistency is crucial for ensuring tunnel construction quality. A mortar consistency meter can quickly and accurately measure mortar consistency, providing construction personnel with data support to help them adjust mortar mix proportions and construction processes based on actual conditions.

[0003] However, remote tunnel construction environments are often harsh, characterized by high temperatures, high humidity, and high dust levels. These environmental factors place higher demands on the accuracy and stability of mortar consistency meters, requiring full consideration of their adaptability and durability. Remote tunnels are also difficult to access and transport, and data processing and feedback mechanisms are often inadequate. Consequently, mortar consistency data cannot be accurately and promptly fed back to construction personnel and quality control personnel, hindering their ability to adjust construction parameters and processes.

[0004] Therefore, it is necessary to design a portable and durable mortar consistency tester for remote tunnel construction conditions to solve the above problems.

[0005] Prior art Chinese patent document 201910241716.3 discloses a mortar consistency density meter, comprising a base, a slide rod, a standard test cone, a mortar cup, a support frame, and a digital display. The slide rod is vertically mounted on the base, the mortar cup is mounted on the base, and one end of the support frame is slidably mounted on the slide rod. In this embodiment, one end of the support frame is sleeved on the slide rod and secured by an adjusting bolt. The other end of the support frame is connected to the digital display, and a cone rod is connected to the upper portion of the standard test cone. The digital display is mounted on the cone rod, which is capable of vertical sliding. The center line of the standard test cone is collinear with the center line of the mortar cup. The standard test cone is provided with a scale that matches the distance the standard test cone descends in the mortar.

[0006] However, the implementation of the above solution presents at least the following technical issues: Traditional mortar consistency measurement typically requires manual stirring, loading the mortar sample, and performing multiple measurements. This process is cumbersome and time-consuming. Furthermore, the mortar sample may not be dense enough due to the presence of air bubbles, affecting the accuracy of the consistency measurement. Therefore, a mortar consistency measurement device is urgently needed. Summary of the Invention

The container allows for quick transfer of the mixed mortar, streamlining the process and reducing human error during mortar transfer.

[0017] 2.

The brake screw precisely controls the cone's position, ensuring a consistent height for each test, minimizing the impact of human factors and improving the repeatability of test results.

[0018] 3. The rotating disc automatically switches containers at different locations to the bottom of the mortar outlet, achieving automated loading, reducing manual intervention, and improving work efficiency and ease of operation. The disc track ensures that the rotating disc moves smoothly along the predetermined path, avoiding shaking or deviation during movement, and improving the stability and reliability of the equipment.

[0019] 4. The vibrating structure promotes dense packing of the mortar, eliminates internal air bubbles, and improves its density, thereby ensuring the accuracy of consistency testing. The motor's power is transmitted to the rotating shaft via a gear drive system, ensuring the stability and efficiency of the vibration process. The eccentric design ensures more uniform and controllable vibration, which helps to achieve uniform density of the mortar and improve the consistency of test results. The U-shaped member contacts the surface of the eccentric, and the reciprocating vibration drives the mounting plate under the chassis to vibrate, effectively compacting the mortar in the container.
