Description

Technical Field

[0001] The invention relates to the technical field of geological core drilling engineering, in particular to a device for transporting a core tube. Background Art

[0002] In geological drilling operations, the core tube is very heavy after being fully mined, and usually requires two to three people to carry it to the core withdrawal site for core withdrawal. The surface of the core tube taken out from the ground is covered with drilling fluid, which makes the heavy core tube difficult to grasp, and the safety risk is high and the labor load is heavy during the transportation process.

[0003] Therefore, a new core tube transporting device is needed. Summary of the invention

[0004] The purpose of the present invention is to provide a new method for transporting geological drilling core tubes, aiming to solve the problems in the background technology, reduce the number of people required to participate in the transport operation, reduce the labor intensity of workers in the transport operation, reduce the safety risks of the transport operation and improve the operation efficiency.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a new type of geological drilling core tube transfer device includes a support frame, a base, a turntable, a baffle, a crossbeam, a roller and a pressure bearing. The turntable, the upper structure and the core tube load are transmitted to the base through the pressure bearing, the lower positioning shaft of the turntable is connected to the center hole of the base through a single-row radial ball bearing, and the turntable can rotate 360 ​​degrees relative to the base.

[0006] Furthermore, evenly distributed tripod stands are arranged below the base.

[0007] Furthermore, a core tube supporting mechanism is arranged above the turntable.

[0008] Furthermore, the core tube supporting mechanism is composed of two baffles and a crossbeam.

[0009] Furthermore, the crossbeam is connected at the center point of the two baffles.

[0010] Furthermore, two rollers are arranged on the crossbeam and are symmetrically distributed along the central axis.

[0011] After adopting the above structure, the positive progress effect of the present invention is that two or three new geological drilling core tube transport devices are used as a group. Relying on the characteristics that the turntable can rotate on the base and the core tube can roll on the roller, the core tube can be easily transported from the front well site to the position of withdrawing the core. Compared with the original two or three people carrying the heavy core tube, after using this device, the worker only needs to put the two ends of the core tube on the roller in turn, push the core tube to roll forward and backward or turn left and right to transport the core tube to the correct location.

[0012] The present invention has a simple structure, reasonable design and convenient manufacturing. The special design of the turntable can effectively support the core tubes with diameters of 89 mm and 76 mm to rotate freely on the base, which greatly reduces the labor burden of workers in moving the core tubes, and can simplify the process of two people's operation to one person, thereby improving the efficiency of drilling auxiliary operations and reducing labor costs.

[0016] Specific implementation and verification

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] like Figure 1 Figure 2 As shown, the geological drilling core tube transport device of the present invention includes a support frame 1, which is composed of three identical hollow steel pipes, which are symmetrically welded to the bottom end surface of a base 2 at an angle of 120 degrees to each other.

[0019] There is a circular groove in the middle of the upper end surface of the base 2, in which a single-row radial ball bearing 6 is installed, and the center hole of the single-row radial ball bearing 6 is connected to the positioning shaft at the lower end of the turntable 7. The upper end surface of the base 2 is connected to the lower end surface of the turntable through the pressure bearing 3.

[0020] Two baffles 5 are axially symmetrically distributed on the upper end surface of the base 2 , and a crossbeam 9 is connected at the center of the baffles 5 .

[0021] Two rollers 8 are symmetrically distributed on the crossbeam 9 .

[0022] A spacer sleeve 4 is installed at the center of the crossbeam 9 to position the roller 8.
