Description

Technical Field

[0001] This utility model relates to the technical field of viscosity testing devices, specifically a viscometer testing device for asphalt materials. Background Technology

[0002] Viscosity testing of asphalt materials generally uses a Blockfield viscometer. The viscometer consists of two parts: one part is composed of a base, column, and head, which is used to control the working state of the rotor; the other part is the testing device, which is used to heat and keep the sample cylinder containing the asphalt material to be tested.

[0003] Current viscometers are equipped with only one testing device, which can only heat one sample container at a time. After heating, it needs to be kept at that temperature for one hour before testing, which is very inefficient. For example, patent application number 202222259705.8, entitled "A Testing Container for a Brinell Viscometer," discloses such a typical testing device that can only heat one sample container at a time.

[0004] Existing technologies also include improved designs that take into account the need to increase testing efficiency. For example, patent application number 202121534094.2, entitled "A Viscosity Testing Device for Waterproof Coatings," discloses a rotatable structure for a viscometer. However, this testing method is not suitable for testing the viscosity of asphalt materials. On the one hand, it requires the use of multiple viscometers, and on the other hand, after the viscometer has tested the asphalt, it will inevitably stick together and cannot be rotated. Moreover, rotating it will cause the asphalt on it to be flung around.

[0005] To address this, the inventors designed a rotatable testing device specifically for testing the viscosity of asphalt materials, thereby improving the efficiency of asphalt material viscosity testing. Summary of the Invention

[0006] To address the technical problems existing in the background art, this utility model provides an asphalt material viscometer testing device.

[0007] The technical solution of this utility model is as follows: A bitumen viscometer testing device, used in conjunction with a viscometer head, includes a support platform, a turntable is arranged above the support platform, a power device for driving the turntable to rotate is arranged inside the support platform, and the support platform is provided with several height adjustment units in the outer area of ​​the turntable. The outer ring above the turntable has several grooves, in which test containers are fixed. A placement slot is opened in the middle of the test container to place the sample tube. A heating layer is set on the outside of the placement slot. A bracket is located at the center of the top of the turntable, and a control unit is installed at the top of the bracket.

[0008] In this way, multiple sample cylinders can be prepared simultaneously or sequentially according to the test requirements. They can be placed in the placement slot of the test container for heating or heat preservation. After the rotor of the viscometer head has finished measuring the asphalt material in one sample cylinder, the rotor can be removed, the turntable can be rotated, and a new rotor can be reattached to continue testing the asphalt material in the next sample cylinder, which greatly improves the testing efficiency.

[0009] As a further improvement, the support platform has a circular structure, the turntable has a cylindrical structure, and the bottom is connected to the drive motor through a gear transmission mechanism.

[0010] The circular support platform and turntable avoid interference when used with the viscometer head, resulting in smoother rotation. Furthermore, the turntable is driven by a gear transmission mechanism and has a self-locking function after reaching its designated position, preventing wobbling during operation.

[0011] Furthermore, several circular grooves are distributed in an array on the outer ring above the turntable. Compression fixing can be achieved by designing the inner diameter of the circular grooves to be in a transitional fit with the outer diameter of the test container. Alternatively, an auxiliary fixing mechanism can be installed on one side of the test container on the upper surface of the turntable to assist in fixing.

[0012] Regarding the design of the bracket, the bracket includes several vertical supports, and a horizontal tray is set on the top of each vertical support. The control unit is mounted on the horizontal tray.

[0013] The control unit is electrically connected to the heating layer of each test container, with the wires arranged along the vertical supports. The control unit can control the switching on and off of the heating layer and temperature adjustment in each test container.

[0014] To prevent the control unit from becoming inconvenient to operate after it rotates to the inside of the turntable, the control unit can be designed to be rotatably connected to a horizontal tray, making it easy to rotate to the operator's face when selecting an operation.

[0015] As a further preferred option, the support frame is higher than the test container to facilitate operation by staff.

[0016] In one implementation, the height adjustment unit is an adjustment screw, which is vertically installed in the outer area of ​​the turntable and is used to adjust the test device to be in a horizontal state.

[0017] As a preferred embodiment, the viscometer head is vertically slidably connected to the base column of the viscometer and can move laterally to facilitate alignment with the central groove of the test container.

[0018] Through the above design, the present invention provides an asphalt material viscometer testing device that can prepare multiple sample cylinders simultaneously or sequentially according to testing requirements. These cylinders are placed in the placement slot of the testing container for heating or heat preservation. After the rotor of the viscometer head has finished measuring the asphalt material in one sample cylinder, the rotor is removed, the turntable is rotated, and a new rotor is reattached to continue testing the asphalt material in the next sample cylinder, greatly improving testing efficiency. Attached Figure Description

[0019] In the attached diagram: Figure 1 A three-dimensional view of the testing device; The components represented by the various reference numerals in the diagram are: 1. Support platform; 2. Turntable; 3. Test container; 4. Bracket; 41. Vertical support; 42. Horizontal tray; 5. Adjusting screw. Detailed Implementation

[0020] See Figure 1 This embodiment provides a viscometer testing device for asphalt materials, which is used in conjunction with a viscometer head. The main body of the viscometer can still use the existing technology, consisting of a base, a column, and a head. The inventive point of this application is mainly focused on the testing device, changing the original testing device that only provides a single test container 3 to a testing device that uses a turntable 2 to drive multiple test containers 3 for cyclic use, thereby reducing the waiting time for asphalt material viscosity testing.

[0021] Specifically, the testing device includes a support platform 1, a turntable 2 is arranged above the support platform 1, a power device for driving the turntable 2 to rotate is arranged inside the support platform 1, and the support platform 1 is provided with several height adjustment units in the outer area of ​​the turntable 2. Several grooves are distributed on the outer ring above the turntable 2. Test containers 3 are fixed in the grooves. The test containers 3 used in this embodiment are the same as the test containers 3 used for asphalt materials in the prior art. No new design is adopted. A placement groove is opened in the middle of the test container 3 for placing the sample cylinder. A heating layer is set on the outside of the placement groove for heating or heat preservation of the asphalt in the sample cylinder.

[0022] A bracket 4 is located at the center of the top of the turntable 2. A control unit is installed at the top of the bracket 4. The bracket 4 is located inside the entire test container 3 to avoid interference with it.

[0023] In this way, multiple sample cylinders can be prepared simultaneously or sequentially according to the test requirements. They can be placed in the placement slot of the test container 3 for heating or heat preservation. After the rotor of the viscometer head has finished measuring the asphalt material in one sample cylinder, the rotor is removed, the turntable 2 is rotated, and a new rotor is reattached to continue testing the asphalt material in the next sample cylinder. This saves waiting time and greatly improves testing efficiency.

[0024] In this embodiment, the support platform 1 is designed as a circular structure with a support frame and a rotating shaft in the middle. The turntable 2 is a cylindrical structure that passes through the rotating shaft, and its bottom is connected to the drive motor through a gear transmission mechanism. Since this is a conventional connection structure for the turntable 2, further details on this prior art will not be provided.

[0025] By designing a circular support platform 1 and a turntable 2, interference with the base below can be avoided when it is used with the viscometer head, resulting in smoother rotation. Moreover, the turntable 2 is driven to rotate via a gear transmission mechanism, and it has a self-locking function after rotating to the correct position to prevent shaking during operation.

[0026] Furthermore, the outer ring above turntable 2 is arrayed with several circular grooves, for example... Figure 1 The diagram shows six circular grooves, which can hold up to six test containers.

[0027] Regarding the fixing and removal of test container 3, a compression fixing can be achieved by designing the inner diameter of the circular groove to be in transition with the outer diameter of test container 3. It can also be removed by rotating it with a little force.

[0028] Of course, an auxiliary fixing mechanism can also be set on one side of the test container 3 on the upper surface of the turntable 2 to assist in fixing. For example, a typical setup is a vertical support with horizontally connected bolts, which can help to compress and fix the test container 3.

[0029] In this embodiment, the main purpose of the bracket 4 is to place the control unit, so that the heating wire of the test container 3 can be electrically connected to the control unit. Therefore, setting it together with the test container 3 on the turntable 2 can offset the problem of messy wiring caused by rotation.

[0030] Regarding the specific design of the bracket 4, the bracket 4 is connected to the center of the turntable 2 by four vertical supports 41. The tops of the four vertical supports 41 jointly support the horizontal tray 42, and the horizontal tray 42 is equipped with a control unit (not shown in the figure, but different styles can be designed as needed).

[0031] The control unit is electrically connected to the heating layer of each test container 3, with the wires arranged along the vertical support 41. The control unit can control the switching on and off of the heating layer and temperature adjustment in each test container 3.

[0032] To prevent the control unit from becoming inconvenient to operate after it rotates to the inside with the turntable 2, the control unit can be designed to be rotatably connected to the horizontal tray 42, so that it can be easily rotated to the front of the operator when selecting an operation.

[0033] As a further preferred option, the height of the support 4 is higher than that of the test container 3 to facilitate operation by staff.

[0034] In this embodiment, the height adjustment unit can be an adjustment screw 5, which is vertically inserted into the outer area of ​​the turntable 2 to adjust the test device to be in a horizontal state.

[0035] To facilitate the use of the viscometer head and the testing device, the viscometer head is vertically slidably connected to the base column of the viscometer and can move laterally to easily align with the central groove of the testing container 3.
