Description
Technical Field
[0001] The utility model relates to the technical field of sampling equipment, in particular to a device for conveniently taking a core from a core barrel. Background Art
[0002] Geological exploration is an essential task in the early stages of modern construction. On the one hand, geological exploration can provide reliable geological data for the project, based on which the engineering design unit can formulate an economical and reasonable construction plan; on the other hand, only by understanding the geological conditions of the project can we better carry out later maintenance and ensure the safe and stable operation of the project.
[0003] The purpose of rock sampling is to determine the mechanical properties of rocks, which is an important part of mastering engineering geological data. In the process of geological exploration, coring guns are generally used for rock sampling. The ignition current is transmitted to the ignition screw through the high-temperature wire in the wiring groove, which detonates the medicine cake filled in the magazine, shoots the core barrel into the formation, obtains the formation sample, and then the steel wire in the wire rope groove brings the core barrel and the entire coring gun to the ground.
[0004] After the core barrel is brought to the surface, the rock samples (cores) in the core barrel are usually taken out by impact or cutting, which can easily cause the core structure to be broken and damaged, reducing the integrity of the sampling, thus affecting the subsequent preservation and research of the core, and thus failing to obtain more complete rock formation information. Summary of the invention
[0005] The utility model provides a device for taking a core from a core barrel. The device is convenient for taking the core from the core barrel, and during the sampling process, the core structure will not be damaged, thereby ensuring its integrity.

[0030] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:
[0031] like Figures 1 to 5 As shown, the utility model provides a device for taking cores from a core barrel, comprising a base 1, a fixing column 2, a fixing seat 3, a tail seat 4, a baffle 1 5, a baffle 2 6, a guide tube 7, a push rod 8, a pressure rod 9, a connecting rod 10 and a core barrel seat 11.
[0032] The base 1 is fixed with a fixed column 2, a fixed seat 3 and a tail seat 4 in sequence. Baffle 1 5 and baffle 2 6 are respectively arranged at both ends of the fixed seat 3, and the bottom ends of baffle 1 5 and baffle 2 6 are fixedly connected to the base 1. One end of the tail seat 4 contacts the side of baffle 2 6. Baffle 1 5 and baffle 2 6 are both provided with through holes, and the through holes on baffle 1 5 and the through holes on baffle 2 6 are coaxial. Baffle 1 5 and baffle 2 6 can play a role in limiting the core barrel seat 11 and the core barrel 15.
[0033] One end of the guide tube 7 is fixedly connected to the side of the baffle 1 5, and the guide tube 7 is coaxial with the through hole on the baffle 1 5. The guide tube 7 is located between the baffle 1 5 and the fixed column 2. The push rod 8 is arranged in the guide tube 7, and the push rod 8 is coaxial with the guide tube 7.
[0034] The end of the pressure rod 9 is hinged to the fixed column 2. One end of the connecting rod 10 is hinged to the push rod 8, and the other end is hinged to the bottom of the pressure rod 9. The pressure rod 9 rotates around the fixed column 2, which can drive the push rod 8 to perform reciprocating linear motion in the guide tube 7.
[0035] The core barrel seat 11 is a semi-cylindrical structure, and a protrusion 13 is provided at the bottom thereof. The upper surface of the fixing seat 3 is an arc-shaped structure, and matches the shape of the core barrel seat 11, and a long hole 14 is provided on the arc-shaped structure of the fixing seat 3. The core barrel seat 11 can be placed on the fixing seat 3, and the protrusion 13 can be inserted into the long hole 14. When used, the core barrel 15 is placed on the core barrel seat 11, and the core barrel seat 11 can ensure that the axis of the core 16 in the core barrel coincides with the axis of the guide tube 7, so that the push rod 8 in the guide tube can push the core 16 out.
[0036] The upper surface of the tailstock 4 is an arc-shaped structure, and matches the outer shape of the core 16 in the core barrel. The tailstock 4 is used to receive the core 16 that is pushed out.

[0039] The utility model provides a device for taking a core from a core barrel, and the working process is as follows:
[0040] The core barrel seat 11 is placed on the fixed seat 3, and then the core barrel 15 is placed on the core barrel seat 11. The pressure rod 9 rotates downward around the fixed column 2, driving the push rod 8 to move linearly in the guide tube 7 toward the core barrel 15, pushing the core 16 in the core barrel onto the tail seat 4, and completing the coring work.
[0041] The pressure rod 9 is rotated upward around the fixed column 2, driving the push rod 8 to move away from the core barrel 15 in the guide tube 7 to perform linear motion, preparing for the next core extraction work.
