In most cases, it can drill into HQ formations with a depth of more than 350 meters and NQ formations with a depth of more than 500 meters. Therefore, most lifting frames are separate and need to be fixed to the fuselage through connectors. Whether it is hinged to the fuselage or bolted to the fuselage, it will cause the installation of the lifting frame to consume a lot of time, thereby increasing the time of auxiliary operations and reducing the overall operation progress.

[0020] The utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0021] Referring to the attached drawings, a core drilling sampling device comprises: a mounting frame 1, a limiting plate 2, a lifting frame 3, a pulley assembly 4, a mounting plate 5, a limiting groove 6, a connecting member 7 and a first rotating member 8. Among them, one side of the mounting frame 1 is slidably connected to the lifting frame 3 through the sliding groove formed by the limiting plate 2, the pulley assembly 4 is installed on the top of the lifting frame 3, the side of the lifting frame 3 away from the mounting frame 1 is provided with a mounting plate 5, the support rod part of the mounting frame 1 is provided with a limiting groove 6, and the limiting groove 6 is slidably connected with a connecting member 7, and the bottom end of the mounting frame 1 is rotatably connected with the first rotating member 8.

[0022] Specifically, before installation, the end of the mounting frame 1 is pre-connected and fixed to the machine body through the first rotating member 8. At this time, the mounting frame 1 is in a horizontal state, and the lifting frame 3 is in a retracted state. After completing the installation of the first rotating member 8 and the machine body, the top end of the electric push rod is connected to the connecting member 7, so that the bottom end of the electric push rod is fixed to another place. At this time, the mounting frame 1 and the electric push rod form a triangle. As the electric push rod is extended, the electric push rod will gradually lift the mounting frame 1 until the mounting frame 1 is supported to a predetermined position. At this time, the connection between the mounting frame 1 and the machine body can be fixed. After that, the lifting frame 3 is pushed out to a suitable height and locked to complete the installation of the lifting mechanism and the machine body. The overall installation is relatively convenient and quick. It can shorten the auxiliary work in the early stage and realize rapid assembly and use.

[0023] Furthermore, the limit plates 2 are symmetrically arranged on the support rod part of the mounting frame 1, and the top of the slide groove formed by the limit plates 2 is through and the bottom is closed. That is, the limit plates 2 are symmetrically arranged on the support rod part of each mounting frame 1, and the sliding installation of the mounting frame 1 and the lifting frame 3 is realized through the limit plates 2. The top is through, so that the lifting frame 3 can move upward along the groove formed by the limit plates 2 to realize the raising or lowering adjustment of the position of the lifting frame 3. The bottom is closed, so the lowest position of the lifting frame 3 is limited.

[0024] Preferably, the top of the limiting plate 2 extends out of the top of the support rod of the mounting frame 1, and the cross section of the extending portion is U-shaped, which can provide sufficient positioning for the mounting frame 1, and the U-shaped cross section can better cooperate with the lifting frame 3.

[0025] Furthermore, a locking member 9 is provided on the protruding portion of the limiting plate 2 extending from the top of the support rod portion of the mounting frame 1, and the locking member 9 is close to the side where the mounting frame 1 is located. The setting of the locking member 9 can maintain the extended position state of the lifting frame 3.

[0026] The connecting member 7 is connected with a second rotating member 10, and the second rotating member 10 is connected with the electric jack, so that when the electric jack is lifted, the angle change can adapt to the lifting of the mounting frame 1, ensuring the stability of the lifting.

[0027] The length of the limit slot 6 is less than the length of the upper support rod of the mounting frame 1, so that the two ends of the limit slot 6 are closed, and the connecting member 7 is not easy to slip out when sliding in the limit slot 6, and the stability and safety are better. The length of the mounting frame 1 is equal to the length of the lifting frame 3. Under the same length, the length of the mounting frame 1 and the lifting frame 3 is set to be equal, which can make the length after storage the shortest. Other size requirements can also be set according to actual use.

[0028] The fixing plate on the first rotating member 8 is fixed to the machine body by bolts, and the pulley assembly 4 and the mounting plate 5 are connected to the lifting frame 3 by bolts. When the first rotating member 8 is fixed to the machine body, the mounting frame 1 is in a horizontal state, and the installation is relatively simple. After the installation of the mounting frame 1 is completed, the pulley assembly 4 and the mounting plate 5 can be further installed, thereby reducing the burden of early installation.

[0029] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, including the combination of various specific technical features in any suitable manner. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
