Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, and in particular to a grease sampling device. Background Technology

[0002] Lubricating oil is a technology-intensive product, a complex mixture of hydrocarbons. Its actual performance is a combination of complex physical or chemical changes. The basic properties of lubricating oil include general physical and chemical properties, special physical and chemical properties, and simulated bench tests.

[0003] In practical work, various types of sampling devices are used in the sampling and testing of lubricating greases in existing technologies. The most common one is the piston suction sampling cylinder. The existing sampling cylinder has a relatively simple function and requires manual holding for sampling, which makes it impossible to perform other operations, increases the labor intensity of manual sampling, and is time-consuming, labor-intensive, and causes many inconveniences.

[0004] Therefore, this utility model provides a grease sampling device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a grease sampling device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a grease sampling device, including a support platform,

[0007] The support platform has a sampling cavity inside, and a bottom positioning cylinder is installed inside the sampling cavity;

[0008] The top of the support platform is equipped with two symmetrically distributed support cylinders. The inside of each of the two support cylinders is slidably connected with a support slide rod. One end of the top of each of the two support slide rods is fixedly connected with a limiting horizontal plate. The inside of the limiting horizontal plate is equipped with a sampling outer cylinder that extends into the sampling inner cavity.

[0009] The sampling outer cylinder is fixedly connected to the bottom positioning cylinder. An internal threaded push rod is rotatably connected inside the sampling outer cylinder. A handwheel is installed on the top of the sampling outer cylinder. One top end of the internal threaded push rod is fixedly connected to the handwheel. One bottom end of the internal threaded push rod, located inside the sampling outer cylinder, is fixedly connected to a connecting rod. The bottom of the connecting rod is fixedly connected to a sampling inner spiral conveying rod extending into the bottom positioning cylinder.

[0010] Symmetrically distributed auxiliary positioning mechanisms are installed on the outer side of the support platform. Each auxiliary positioning mechanism includes a limiting block. Equidistantly distributed limiting blocks are installed on the outer side of the support platform. A supporting connecting plate is fitted on the outer side of each limiting block. A limiting frame is fitted on one end of each of the four supporting connecting plates on the same side. A supporting base plate is fixedly connected to the bottom end of each limiting frame. During normal sampling operations, the internal threaded push rod is rotated inside the sampling outer cylinder by manually turning the handwheel. This drives the connecting rod at the bottom of the internal threaded push rod to move downwards. Under the limiting position of the sampling inner cylinder, opening the valve will drive the sampling inner spiral conveyor rod to gradually slide out of the bottom positioning cylinder for normal sampling. After sampling is completed, the handwheel can be turned in the opposite direction to reset the device. The overall structure is simple and easy to operate, facilitating rapid sampling. The support cylinder and supporting slide rod work together to facilitate height adjustment of the limiting horizontal plate. At the same time, the existence of the overall equipment facilitates sampling needs in different operating scenarios, thereby improving the overall flexibility of the equipment.

[0011] In a preferred embodiment, heating plates are evenly distributed inside the outer sampling cylinder and outside the connecting rod. A valve is installed outside the bottom positioning cylinder. An inner sampling cylinder is installed inside the bottom positioning cylinder and outside the inner sampling spiral conveying rod. The inner sampling cylinder is used to protect the inner sampling spiral conveying rod. Limiting rods are fixedly connected to the bottom of each support base plate. Two mounting slots are opened inside each limiting frame. Limiting shafts that cooperate with the limiting of two supporting connecting plates are installed inside each of the two mounting slots. By opening mounting slots inside the limiting frame to cooperate with the limiting shafts, the connection of multiple supporting connecting plates can be achieved.

[0012] In a preferred embodiment, two symmetrically distributed casters are installed on both sides of the support platform. The casters are located on one side of the auxiliary positioning mechanism. The four casters are used to drive the overall equipment to move to the required work location, improving the ease of equipment movement. The bottom of each support cylinder is fixedly connected to a positioning base plate, and the bottom of each positioning base plate is fixedly connected to the support platform. One side of each support cylinder is threaded with a positioning bolt that is used to limit the corresponding support slide rod. After removing the positioning bolt, the support slide rod is manually pulled out from the corresponding support cylinder until it is moved to the required height. The positioning bolt is used for positioning, and the support cylinder and positioning base plate provide overall support for the limiting cross plate.

[0013] In a preferred embodiment, a lighting lamp is fixedly connected to the top of the limiting horizontal plate and to one side of the sampling outer cylinder, and a distance sensor is fixedly connected to the inside of the sampling inner cavity and to one side of the bottom positioning cylinder. The distance sensor is used to monitor the distance between the equipment and the sampling source when sampling is performed by the internal spiral conveyor rod. The lighting lamp is used for auxiliary lighting to facilitate nighttime operations.

[0014] In a preferred embodiment, the support platform is fixedly connected to a control panel on one side adjacent to the four casters. The distance sensor, lighting, heating plate, and valves are all electrically connected to the control panel. The control panel is used to control the operation of the distance sensor, lighting, heating plate, and valves, thereby realizing unified management of the electrical equipment.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] By setting up a support platform, a limiting cross plate, and an auxiliary positioning mechanism, during use, the control panel is opened. The sampling inner cylinder is used to protect the internal spiral conveyor rod. The heating plate is used for heat preservation during sampling, improving the flexibility of the equipment during sampling. The distance sensor is used to monitor the distance between the equipment and the sampling source when sampling through the internal spiral conveyor rod. The lighting is used for auxiliary lighting to facilitate nighttime operation. Multiple support connecting plates can be connected by installing a mounting groove inside the limiting frame to cooperate with the limiting shaft. The positioning bolts are removed, and the support slide rod is manually pulled out from the corresponding support cylinder until it moves to the required height. Positioning is then performed using the positioning bolts. The limiting cross plate is then positioned as a whole by the support cylinder and the positioning base plate. The equipment features four omnidirectional casters for easy movement to the desired work location, enhancing its mobility. During normal sampling, manually turning the handwheel rotates the internal threaded push rod inside the sampling outer cylinder, driving the connecting rod at the bottom of the push rod downwards. Under the limit of the sampling inner cylinder, opening the valve allows the internal spiral conveyor rod to gradually slide out of the bottom positioning cylinder for normal sampling. After sampling, reversing the handwheel resets the equipment. The overall structure is simple and easy to operate, facilitating rapid sampling. The support cylinder and support slide rod work together to easily adjust the height of the limit plate. Furthermore, the overall equipment facilitates sampling in various work scenarios, improving its overall flexibility. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-4 As shown, this embodiment provides a technical solution: a grease sampling device, including a support platform 1, a sampling cavity 11 is opened inside the support platform 1, and a bottom positioning cylinder 45 is installed inside the sampling cavity 11; two symmetrically distributed support cylinders 22 are installed on the top of the support platform 1, and a support slide rod 24 is slidably connected inside the two support cylinders 22. A limiting horizontal plate 2 is fixedly connected to one end of the top of the two support slide rods 24, and a sampling outer cylinder 4 extending into the sampling cavity 11 is installed inside the limiting horizontal plate 2;

The bottom of the connecting rod 42 is fixedly connected to a sampling inner spiral conveying rod 46 extending into the bottom positioning cylinder 45. In order to improve the connection stability of the handwheel 21 and the inner threaded push rod 41, when not in operation, the two can be limited by tightening the lock nut, thereby preventing the equipment from resetting on its own.

[0029] In this scheme, symmetrically distributed auxiliary positioning mechanisms 3 are installed on the outer side of the support platform 1. The auxiliary positioning mechanism 3 includes a limiting block 31. The supporting platform 1 is equipped with equidistantly distributed limiting blocks 31. Each limiting block 31 is fitted with a supporting connecting plate 32. One end of each of the four supporting connecting plates 32 on the same side is fitted with a limiting frame 33. The bottom end of each limiting frame 33 is fixedly connected to a supporting base plate 36. During normal sampling operations, the internal threaded push rod 41 is rotated inside the sampling outer cylinder 4 by manually rotating the handwheel 21, thereby driving the internal threaded push rod. The connecting rod 42 at the bottom of 41 moves downward. Under the limit of the sampling inner cylinder 44, the valve 47 is opened, which will drive the inner spiral conveying rod 46 to gradually slide out of the bottom positioning cylinder 45 for normal sampling. After sampling is completed, the handwheel 21 can be rotated in the opposite direction to reset the process. The overall structure is simple and easy to operate, and it is convenient and quick to sample. The support cylinder 22 and the support slide rod 24 work together to facilitate the height adjustment of the limit plate 2. At the same time, the existence of the overall equipment facilitates the sampling needs of different working scenarios, thereby improving the overall equipment's flexibility of use.

[0030] Going a step further, such as Figures 1-4 As shown: In this scheme, heating plates 43 are evenly distributed inside the outer sampling cylinder 4 and outside the connecting rod 42. A valve 47 is installed outside the bottom positioning cylinder 45. A sampling inner cylinder 44 is installed inside the bottom positioning cylinder 45 and outside the inner sampling spiral conveying rod 46. The sampling inner cylinder 44 is used to protect the inner sampling spiral conveying rod 46. The heating plates 43 are used to assist in heat preservation during sampling, which improves the flexibility of the equipment during sampling.

[0031] In this scheme, a lighting lamp 26 is fixedly connected to the top of the limiting horizontal plate 2 and to one side of the sampling outer cylinder 4. A distance sensor 12 is fixedly connected to the inside of the sampling inner cavity 11 and to one side of the bottom positioning cylinder 45. The distance sensor 12 is used to monitor the distance between the equipment and the sampling source when sampling through the sampling inner spiral conveyor rod 46. The lighting lamp 26 is used for auxiliary lighting to facilitate nighttime operation.

[0032] In this scheme, the support platform 1 is located on one side adjacent to the four casters 14 and is fixedly connected to the control panel 13. The distance sensor 12, the lighting lamp 26, the heating plate 43 and the valve 47 are all electrically connected to the control panel 13. The control panel 13 is used to control the operation of the distance sensor 12, the lighting lamp 26, the heating plate 43 and the valve 47, realizing the unified management of electrical equipment.

[0033] Going a step further, such as Figure 4As shown: In this solution, the bottom of the support base plate 36 is fixedly connected to the limit rod 37. The inside of the limit frame 33 is provided with two mounting slots 34. The inside of the two mounting slots 34 is provided with a limit shaft 35 that cooperates with the limit of the two support connecting plates 32. By providing mounting slots 34 inside the limit frame 33 to cooperate with the limit shaft 35 for installation, the connection of multiple support connecting plates 32 can be achieved.

[0034] Going a step further, such as Figures 1-2 , Figure 4 As shown, in this scheme, two symmetrically distributed casters 14 are installed on both sides of the support platform 1. The casters 14 are located on one side of the auxiliary positioning mechanism 3. The four casters 14 are used to drive the overall equipment to move and process until the required work location, which improves the convenience of equipment movement.

[0035] Going a step further, such as Figures 1-3 As shown, in this scheme, the bottom of each support cylinder 22 is fixedly connected to a positioning base plate 23, and the bottom of each positioning base plate 23 is fixedly connected to the support platform 1. Each side of the support cylinder 22 is threadedly connected to a positioning bolt 25 for use in limiting the corresponding support slide rod 24. After removing the positioning bolt 25, the support slide rod 24 is manually pulled out from the inside of the corresponding support cylinder 22 until it is moved to the required height. The positioning is performed by the positioning bolt 25, and the support cylinder 22 and the positioning base plate 23 provide overall support for the limiting horizontal plate 2.

[0036] Working principle:

[0037] like Figures 1-4 As shown: By setting up the support platform 1, the limiting horizontal plate 2 and the auxiliary positioning mechanism 3, when using the device, open the control panel 13, fix the entire device at the sampling point, keep the sampling source above the sampling outer cylinder 4, and then adjust it according to the installation height of the sampling outer cylinder 4.

[0038] The sampling inner cylinder 44 is used to protect the inner spiral conveyor rod 46, and the heating plate 43 is used to assist in heat preservation during sampling, which improves the flexibility of the equipment during sampling.

[0039] To improve the connection stability between the handwheel 21 and the internal threaded push rod 41, when not in operation, the lock nut can be tightened to limit their movement, thereby preventing the equipment from automatically resetting.

[0040] The distance sensor 12 is used to monitor the distance between the equipment and the sampling source when sampling is performed through the internal spiral conveyor rod 46. The lighting lamp 26 is used for auxiliary lighting to facilitate nighttime operation. The control panel 13 is used to control the operation of the distance sensor 12, the lighting lamp 26, the heating plate 43 and the valve 47, realizing unified management of the power equipment.

[0041] By providing an installation groove 34 inside the limiting frame 33 to cooperate with the limiting shaft 35 for installation, multiple support connecting plates 32 can be connected. Remove the positioning bolt 25 and manually pull the support slide rod 24 out from the corresponding support cylinder 22 until it is moved to the required height. Position it by the positioning bolt 25. The limiting horizontal plate 2 is supported as a whole by the support cylinder 22 and the positioning base plate 23.

[0042] Four casters 14 are used to drive the overall equipment to move to the required work location, improving the ease of equipment movement.

[0043] During normal sampling operations, manually turning the handwheel 21 drives the internal threaded push rod 41 to rotate inside the sampling outer cylinder 4, which in turn drives the connecting rod 42 at the bottom of the internal threaded push rod 41 to move downwards. Under the limit of the sampling inner cylinder 44, opening the valve 47 will drive the sampling inner spiral conveying rod 46 to gradually slide out of the bottom positioning cylinder 45 for normal sampling. After sampling is completed, the handwheel 21 can be reversed to reset the process. The overall structure is simple and easy to operate, facilitating rapid sampling. The support cylinder 22 and the support slide rod 24 work together to facilitate height adjustment of the limit plate 2. At the same time, the existence of the overall equipment facilitates sampling needs in different operating scenarios, thereby improving the overall equipment's flexibility of use.
