The lifting device (4) drives the lifting frame (3) to move up and down. The coring barrel (2) is connected to the lifting frame (3). An adjusting disk (5) is slidingly provided in the coring barrel (2). A threaded rod (6) and a limiting rod (7) are provided on the adjusting disk (5). The threaded rod (6) and the limiting rod (7) pass through the top of the coring barrel (2). A turntable (8) is rotatably provided on the coring barrel (2). The turntable (8) is provided with a screw threaded rod ( 6) matching threaded holes (9), a plurality of grooves (10) are provided on the side wall of the turntable (8), a locking mechanism (11) is provided on the core barrel (2), the locking mechanism (11) includes a sliding groove (12), an arc plate (13), a convex strip (15) and a spring (14), a plurality of convex strips (15) are provided on the arc plate (13), the spring (14) is arranged in the sliding groove (12), the spring (14) presses against the plurality of convex strips (15) on the arc plate (13) and engages with the plurality of grooves (10), and an adjusting mechanism (16) for adjusting the preload force of the spring (14) is provided on the spring (14).

[0024] The core barrel (2) is provided with an adjusting disk (5), the adjusting disk (5) is provided with a threaded rod (6), and the core barrel (2) is provided with a turntable (8) rotatably connected to the turntable (8). The position of the adjusting disk (5) in the core barrel can be adjusted by the threaded connection between the turntable (8) and the threaded rod (6). The turntable (8) and the threaded rod (6) are prevented from synchronously moving toward each other by setting a limit rod (7). The turntable (8) can be fixed on the core barrel by a locking mechanism (11) provided on the core barrel, thereby ensuring the length of the threaded rod (6) in the core barrel, that is, ensuring that the position of the adjusting disk (5) in the core barrel is fixed, and preventing the convex strip (15) from accidentally rotating under a non-human force state. The above technical solution is adopted, which facilitates the operation of the operator to ensure that the core length is fixed each time during the construction process, and can obtain a concrete core with a precise value, thereby facilitating the construction of the operator, reducing the difficulty of operation, and improving the efficiency of core collection.

[0025] Example 2:

[0026] Reference Figures 1 to 4 In combination with the technical solution of Example 1, in this embodiment, the adjustment mechanism (16) includes a screw rod (17), a rotating handle (18), and an abutment plate (19). The sliding groove (12) is provided with a screw hole that cooperates with the screw rod (17). The screw rod (17) is provided with a rotating handle (18). The abutment plate (19) abuts against the spring (14).

[0027] Specifically, the screw rod (17) is provided with an abutting column (20) for abutting against the arc plate (13).

[0028] Specifically, the groove (10) is a trapezoidal groove (10), and the cross section of the ridge (15) is a trapezoid.

[0029] By rotating the handle (18) on the locking mechanism, the handle (18) drives the screw rod (17) to move in the screw hole, and an abutment plate (19) is provided on the screw rod (17) in the sliding groove (12), and the abutment plate (19) abuts against the spring (14) in the sliding groove (12). As the screw rod (17) goes deep into the screw hole, the spring (14) in the sliding groove (12) is exerted with greater pressure by the abutment plate (19) on the screw rod (17), pushing the arc plate (13) close to the turntable (8). When the screw rod (17) is completely screwed into the screw hole, the abutment column (20) on the screw rod (17) is completely pressed against the arc plate (13) in the sliding groove (12), pushing the trapezoidal convex strips (15) on the arc plate (13) to be clamped in the trapezoidal grooves (10) on the turntable (8), locking the turntable (8). The position of the turntable (8) is prevented from being offset when the core barrel rotates. Because of the spring (14), when the abutment column (20) is not completely pressed against the arc plate (13), the abutment disk (19) compresses the spring (14), so that the spring (14) has a pressing force on the arc plate (13). The pressure on the arc plate (13) is transmitted to the convex strip (15), and the convex strip (15) is clamped in the groove (10) on the turntable. When the staff rotates the turntable (8), the number of rotations can be clearly perceived, so as not to rotate excessively. When it is rotated to the appropriate position, the abutment column (20) is driven to completely press against the arc plate (13), driving the convex strip (15) to be completely clamped in the groove (10), locking the position of the turntable (8), and preventing the convex strip (15) from accidentally rotating under the condition of non-human force.

[0032] Specifically, the gear ratio of the second gear (22) to the first gear (21) is 1:3.

[0033] A gear meshing portion is provided on the turntable (8), a first gear (21) meshes with the meshing portion of the turntable (8), a second gear (22) meshes with the first gear (21), the first gear (21) and the second gear (22) are arranged on the core barrel via a support shaft, a handle (23) is installed on the second gear (22), and rotating the handle (23) drives the second gear (22) to rotate, thereby driving the first gear (21) to rotate, and the gear ratio of the second gear (22) to the first gear (21) is 1:3, so that rotating the handle (23) is more labor-saving.

[0034] Example 4:

[0035] Reference Figures 1 to 4 In combination with the technical solutions of Examples 1 to 3, in this embodiment, a scale line (24) is provided on the limit rod (7).

[0036] Specifically, the lifting device (4) is a hydraulically driven cylinder.

[0037] Specifically, a driving motor (25) is provided on the lifting frame (3), and the driving motor (25) is in transmission connection with the coring barrel (2) and is used to drive the coring barrel (2) to rotate.

[0038] When the construction workers need to take a concrete core of precise length, they can adjust the distance between the adjusting disk (5) and the bottom of the coring barrel (2) by observing the scale line (24) on the limit rod (7), and then lock the position of the turntable (8) to take a concrete core of precise value. The coring barrel (2) is connected to the lifting frame (3), and the movement of the lifting frame (3), that is, the movement of the coring barrel (2), is adjusted by a hydraulic drive cylinder. A driving motor (25) is provided on the lifting frame (3), and the driving motor (25) is connected to the coring barrel through a shaft transmission to drive the coring barrel to rotate.
