Description

Technical Field

[0001] This utility model relates to the field of automated pour point testing technology, specifically to a lifting and rotating structure for pour point testing. Background Technology

[0002] Pour point, an important indicator of fuel oil quality, generally refers to the lowest temperature at which the fuel oil can flow freely. As the temperature decreases, the fluidity of fuel oil decreases until it solidifies and loses its fluidity at a certain temperature. By definition, the higher the pour point, the worse the fluidity of the fuel oil at ambient temperature.

[0003] In existing technologies for automated pour point testing, such as Chinese patent CN205120629U, two motors are used to handle lifting and rotation respectively. This structure is not only complex but also relatively expensive. The sample clamping section uses a spring-loaded test tube rack, requiring the operator to manually fix the test tubes to the equipment. This increases the operator's workload and, with the aging of the springs, also increases the potential risks of the test. Utility Model Content

[0004] The purpose of this invention is to propose a lifting and rotating structure for pour point testing.

[0005] To achieve the objective of this utility model, the technical solution adopted is as follows:

[0006] A lifting and rotating structure for pour point testing, comprising:

[0007] One installation base,

[0008] A vertical track is provided on the mounting base;

[0009] A set of follower wheels is provided on the track and moves up and down along the track. A bearing is provided on the follower wheel set and a rotating shaft is provided through the bearing. An electric claw is provided at one end of the rotating shaft.

[0010] The electric gripper holds the test tube containing the sample;

[0011] The lifting mechanism is connected to the bearing via a lifting mounting plate;

[0012] After the electric cylinder drives the lifting mechanism to rise and fall, it drives the lifting mounting plate to rise and fall, thereby driving the follower wheel group to move up and down along the track.

[0013] In a preferred embodiment of this utility model, one side of the follower wheel assembly is mounted in contact with the lower end of the bearing via a bearing mounting plate.

[0014] In a preferred embodiment of this utility model, a flange is provided on the upper end of the bearing, and the lifting mounting plate is provided with mounting holes and is installed in contact with the flange.

[0015] In a preferred embodiment of this utility model, the electric cylinder is disposed on one side of the mounting base.

[0016] In a preferred embodiment of this invention, the opening and closing of the electric gripper is driven by a motor.

[0017] In a preferred embodiment of this invention, the rotating shaft is driven by an electric cylinder.

[0018] In a preferred embodiment of this utility model, the track is a first track and a second track, the arc track is disposed at the upper end of the first track, and the follower wheel assembly moves along the first track;

[0019] The rotating shaft moves along the second track.

[0020] The beneficial effects of this utility model are as follows:

[0021] The mechanical structure for automatically gripping and rotating samples in pour point experiments provided by this invention mainly employs an electric gripper fixed to a rotating shaft. The required experimental actions are achieved by the rotating shaft and a follower wheel sliding on a track, and power is provided by a single-axis electric cylinder. This significantly improves the automation and accuracy of the experiment. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following descriptions, well-known structures and technologies have been omitted to avoid unnecessary confusion regarding the concept of this utility model.

[0027] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] like Figure 1-4 The lifting and rotating structure shown includes a mounting base 9, on which a vertical track 7 is provided.

[0029] A follower wheel assembly 5 is provided on the track 7, which moves up and down along the track 7. A bearing 3 is provided on the follower wheel assembly 5. Specifically, one side of the follower wheel assembly 5 is installed in contact with the lower end of the bearing 3 through a bearing mounting plate 6.

[0030] The rotating shaft 2 is installed inside the bearing 3. An electric claw 1 is installed at one end of the rotating shaft 2. The electric claw 1 is used to clamp the test tube 10 containing the sample after opening and closing.

[0031] The follower wheel assembly 5 is connected to the bearing 3 and the rotating shaft 2 via the bearing mounting plate 6. The track plate 72 of the track 7 can accommodate the rotating shaft 2 and the follower wheel assembly 5 to move on the track 7.

[0032] Track 7 consists of a first track 701 and a second track 702, with an arc track 71 located at the upper end of the first track 701.

[0033] The purpose of setting the arc track 71 is to facilitate the rotation of the follower wheel group 5 in motion in conjunction with the rotating shaft 2.

[0034] The follower wheel assembly 5 moves along the first track 701, and the rotating shaft 2 moves along the second track 702.

[0035] The lifting mechanism 11 is connected to the bearing 3 through the lifting mounting plate 4. Specifically, the upper end of the bearing 3 is provided with a flange 31, and the lifting mounting plate 4 is provided with a mounting hole 41 and is installed in contact with the flange 31.

[0036] The electric cylinder 8 drives the lifting mechanism 11 to lift and lower, which in turn drives the lifting mounting plate 4 to lift and lower, thereby driving the follower wheel group 5 to move up and down along the track 7.

[0037] The electric cylinder 8 is located on one side of the mounting base 9. Installing the track 7 and the electric cylinder 8 on the same mounting base 9 can effectively improve the smoothness of the lifting and rotating movements.

[0038] The opening and closing of the electric gripper 1 is driven by a built-in motor, and the rotating shaft 2 is driven by an electric cylinder 8. The rotation of the rotating shaft 2 drives the electric gripper 1 to rotate.

[0039] After the electric gripper 1 descends from the electric cylinder 8 to pick up the test tube 10, it rises to the upper part of the track 7. The follower wheel 5 passes through the arc track 71 of the track 7 and cooperates with the rotating shaft 2 to complete a rotation of 0°-90° before descending to put the sample 10 back into the bath below for continued cooling.

[0040] This invention automates the pour point test by using a single power source, controlling the rotation angle with a track, and using an electric gripper to pick up the sample. It also simplifies the structure, reduces costs to some extent, and improves the accuracy of the experiment.

[0041] Although the present invention has been described in detail through the preferred embodiments, it should be understood that the description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the description. Therefore, the alarm range of the present invention should be defined by the appended claims.
