[0002] Petroleum asphalt is a product of crude oil processing, which is usually black or dark brown solid at room or low temperature. Since solid asphalt is hard and difficult to sample directly, laboratories generally use the method of heating the asphalt as a whole until it flows. However, this sampling method has disadvantages: on the one hand, asphalt will produce toxic and irritating fumes during high-temperature heating, which seriously pollutes the environment and health; on the other hand, the heating process can easily cause the local temperature of the asphalt to be too high, causing asphalt aging and affecting the accuracy of the experiment. In addition, for large asphalt storage barrels or other containers, the overall heating method is not only time-consuming and labor-intensive, but also easy to cause resource waste when only a small amount of sampling is required.

[0026] like Figure 1 and Figure 2 The solid asphalt sampling device shown in the figure comprises a frame 10, and a telescopic assembly 20 and a grab bucket 30 arranged at both ends of the frame 10; the telescopic assembly 20 is fixed to the top of the frame 10; the grab bucket 30 is movably connected to the bottom of the frame 10; the output end of the telescopic assembly 20 is connected to the grab bucket 30 and is movably connected to the grab bucket 30;

[0027] The grab bucket 30 is provided with a cavity inside, and a heating device such as an electric heating wire 32 and a temperature sensor 33 is provided in the cavity. The integrated design of heating and sampling functions simplifies the equipment structure and improves the operating efficiency. The rotation sampling can realize automatic operation, and improve the consistency and accuracy of sampling. The temperature inside the grab bucket 30 is monitored in real time by the temperature sensor 33 to ensure that the asphalt is heated to the optimal sampling temperature, thereby improving the accuracy and consistency of sampling.

[0028] The utility model provides a solid asphalt sampling device, which turns on the telescopic motor 21 and the temperature control switch, so that the heated grab 30 rotates and samples under the drive of the telescopic motor 21. The heated grab 30 softens the asphalt, and the grab 30 can obtain asphalt samples more evenly during the rotation process, reducing the problem of uneven sampling caused by hard blocks. The utility model integrates the heating and sampling processes in the grab 30, simplifying the operating steps. The operator does not need to manually handle the high-temperature asphalt, reducing the difficulty of operation. The utility model avoids environmental pollution, low efficiency and other problems in the solid asphalt sampling process without changing the physical and chemical properties of the asphalt, and has the characteristics of energy saving, environmental protection, convenience and speed. The utility model can be used for sampling and quality control of solid asphalt and other high-viscosity materials.

[0029] Specific as Figure 1 As shown, the grab 30 includes two grippers 31 arranged opposite to each other. The edges of the grippers 31 are wedge-shaped, which enhances the penetration ability of the grippers 31, allowing them to easily insert and separate solid asphalt, which is beneficial for penetration and sampling, and realizes a faster and more efficient sampling process. The output end of the telescopic assembly 20 is movably connected to the top ends of the two grippers 31; the center ends of the two grippers 31 are movably connected to the bottom end of the frame 10. In the present application, the two grippers 31 are arranged opposite to each other, and can apply force evenly during sampling, thereby obtaining a more uniform sample. The synchronous movement of the grippers 31 ensures the uniformity of sampling and avoids the problem of sample deviation caused by unilateral sampling.

[0030] The telescopic assembly 20 includes a telescopic motor 21, a telescopic rod 22, a sleeve 23 and a connecting rod 24 which are arranged in sequence from top to bottom. The telescopic motor 21 and the sleeve 23 are respectively fixedly connected to the frame 10, and one end of the telescopic motor 21 away from the telescopic rod 22 is fixed to the top of the frame 10. The telescopic rod 22 is fixed to the bottom end of the telescopic motor 21; and is movably connected with the sleeve 23, and the free end of the telescopic rod 22 is movably connected with the top of the connecting rod 24. Through the above arrangement, the telescopic motor 21 can accurately control the movement of the telescopic rod 22, and realize accurate control of the position and movement of the gripper 31. Ensure the stability and accuracy of the grab 30 during the sampling process, thereby improving the accuracy and efficiency of sampling. Among them, the telescopic rod 22 is movably connected with the sleeve 23, providing good mechanical support and guidance, ensuring the stability and anti-bending performance of the telescopic rod 22 during the movement, and improving the structural stability and reliability of the device.

[0031] Specifically, two connecting rods 24 are provided, and the bottom ends of the two connecting rods 24 are movably connected to the top ends of the two grippers 31, respectively. This ensures that the grippers 31 can move synchronously and coordinately during operation. The synchronization of the grippers 31 is improved, making the sampling action smoother and more consistent, and avoiding sampling deviation caused by uneven force on one side. The two connecting rods 24 provided in the present application can increase the strength and stability of the structure, reduce the excessive pressure that a single connecting rod 24 may bear, reduce the risk of mechanical failure, and extend the service life of the device.

[0032] In order to realize automatic control, Figure 2 As shown, a control system 40 is also provided above the frame 10, and the control system 40 includes a micro display 41, and a telescopic motor switch 42, a temperature adjustment switch 43 and a power plug 44 electrically connected to the micro display 41. The integrated heating and rotating device can be remotely controlled, reducing the risk of the operator directly contacting the high-temperature material and improving the safety of the sampling process. The micro display 41 can display the current operating status in real time, including the position, temperature, sampling progress and other information of the gripper 31, so that the operator can monitor and adjust the working status of the equipment in real time to ensure the accuracy and efficiency of the sampling process.

[0033] The temperature regulating switch 43 is electrically connected to the electric heating wire 32 and the temperature sensor 33, and is used to adjust the working temperature of the electric heating wire 32. The operator can accurately adjust the temperature inside the grab 30 as needed to ensure that the asphalt is sampled at the most suitable temperature and improve the sampling quality. The telescopic motor switch 42 is electrically connected to the telescopic motor 21, and is used to adjust the working speed of the telescopic motor 21. The operator can accurately control the telescopic speed of the grab 30 according to specific sampling requirements, which helps to improve the accuracy and efficiency of the sampling operation. For example, when sampling harder asphalt, a slower speed can be selected to ensure the stability of the grab 30 and the sampling quality; when sampling softer asphalt, a faster speed can be selected to improve work efficiency.

[0034] Preferably, the heating device and the grab 30 are made of high temperature resistant and corrosion resistant materials, such as stainless steel, aluminum alloy, Teflon coating, etc., to ensure long-term use and safe operation in high temperature and harsh environments. The control system 40 of the electric heating wire 32 includes an overheat protection mechanism, which further improves the safety of operation.

[0035] Please continue to refer to Figure 1Insulated handrails 11 are fixedly connected to both sides of the frame 10. A stable gripping point is provided for the operator, making it more stable and safe to operate the equipment in a high temperature environment, reducing the risk caused by equipment vibration or improper operation, and improving the operation accuracy. In addition, the insulating handrails 11 can effectively isolate heat and prevent heat in a high temperature environment from being transferred to the operator's hands, ensuring that the operator will not be burned by contacting high temperature components during high temperature operation, thereby improving the comfort and safety of operation.
