[0034] The multifunctional composite experimental device of this embodiment is an experimental device used to apply torque and drilling pressure to the drilling instrument tool under rotation and water test conditions to test its reliability and performance indicators. The specific use is as follows:

The above-mentioned clamping and detaching device 34 is used to clamp the above-mentioned tool to be tested 1 and to detach the above-mentioned tool to be tested 1. The above-mentioned dynamic test platform body 31 is provided with a cavity, and the side wall of the above-mentioned cavity is provided with the above-mentioned second water outlet.

[0059] In the above embodiment, one end of the tool 1 to be tested is sealed and connected to the second main shaft, and the other end is connected to the load rotating device 33 (and can rotate relatively). The power loading device 32 can drive the first running gear to move along the rack 35 through the first power rotating mechanism 3211, so that the power loading device 32 itself moves, so as to adapt to the assembly of the tool 1 to be tested of different lengths. At the same time, it can also load axial force (that is, pressure) on the tool 1 to be tested. At the same time, the tool 1 to be tested is driven to rotate by the power loading device 32 to load the torque of the tool 1 to be tested. At the same time, the load rotating device 33 is used to load the torque of the tool 1 to be tested, and the pressure and torque loaded by the power loading device 32 are used to test the torque and pressure loaded on the tool 1 to be tested. In this structural design, during the process of loading pressure and torque, it is ensured that the liquid can circulate in the tool 1 to be tested. At the same time, in the simulation experiment, since the power loading device 32 is displaced along the rack 35 as a whole, that is, the overall displacement applies axial force, and the drilling pressure is applied without affecting the rotation of the tool 1 to be tested, it can be ensured that the two actions of rotation and drilling pressure do not affect each other.

[0060] In this embodiment, the dynamic test bench body 31 is composed of three sections, each section is welded into a rectangular cube by homogeneous steel plates, and steel plates of the same material and thickness are uniformly distributed inside as reinforcement ribs to increase the load-bearing capacity. Two parallel racks 35 are welded on the upper part of the platform body, and equal-length steel is used to weld between the racks 35 to ensure parallelism. Equidistant pin holes are opened at the bottom and fixed with expansion bolts to prevent displacement. The three sections of the platform body are positioned and connected using positioning bolts to ensure straightness, so that the three sections of the platform body are in a straight line. The advantages of adopting a three-section design are: first, it is convenient for transportation. Freight vehicles that are too long cannot meet transportation needs, and they can be disassembled into three sections for freight; second, whether to choose full-size installation or partial installation can be selected according to the site and actual use needs.

[0061] As a preferred embodiment, Figure 7As shown, the power loading device 32 includes a main housing 321, two transmission main shafts 322, two second rotation driving devices 323, a main transmission gear 324, two auxiliary transmission gears 325 and the second main shaft. The second main shaft horizontally penetrates the main housing 321 along the length direction of the dynamic test bench body 31 and is rotatably connected to the main housing 321. The two transmission main shafts 322 are horizontally installed in the main housing 321 along the length direction of the dynamic test bench body 31 and are respectively rotatably connected to the main housing 321. The main transmission gear 324 is coaxially installed on the second main shaft. The two auxiliary transmission gears 325 are coaxially installed on the two transmission main shafts 322 and are respectively engaged with the upper two sides of the main transmission gear 324. The two second rotation driving devices 323 are respectively installed outside the main housing 321 and are respectively transmission-connected to one end of the two transmission main shafts 322 for driving the transmission main shafts 322 to rotate.

[0062] In the above embodiment, two second rotation driving devices 323 are used to jointly load the second spindle with rotational power. The second rotation driving device 323 uses a hydraulic motor, and the spindle speed can be infinitely adjusted by changing the flow rate. A speed sensor is installed on the second spindle, which is connected to the console via a data cable, and the speed data can be transmitted to the console in real time to adjust the speed as needed. At the same time, because a dual-motor design is adopted, sufficient torque is output to ensure that it is sufficient.

[0063] As a preferred embodiment, the load rotating device 33 includes an oil tank 331, a pump group 332, a load motor 333, two short shafts, a torque sensor 334, a pressure sensor 335 and a water distributor 336.

The two short shafts are coaxially mounted on a support frame, and the torque sensor 334 is connected between the two. The support frame is arranged at one end of the dynamic test bench body 31 and is connected to the first The two main shafts are coaxially distributed, the output shaft of the load motor 333 is connected to one of the short shafts, and the end of the other short shaft is sequentially connected to the pressure sensor 335 and the water divider 336. The dynamic test bench body 31 has a water tank arranged along its length direction. The water divider 336 is connected to a pipeline that is connected to its inner cavity and extends into the water tank. One end of the water tank is provided with the second water outlet, and the other end of the tool to be tested 1 is rotationally sealed and connected to and communicated with an end of the water divider 336 away from the pressure sensor 335.

[0064] In this embodiment, the load rotating device 33 uses hydraulic pressure and a hydraulic motor. The output shaft of the load motor 333 is also connected to an overrunning clutch. By docking the tool with the overrunning clutch, the direction opposite to that of the second main shaft can be achieved. The magnitude of the load torque can be controlled by changing the return oil flow of the hydraulic motor. At the same time, this method can not only output torque dynamically, but also apply torque statically, that is, when the tool remains non-rotating, the load motor 333 is driven to rotate, thereby outputting torque. During the test process, the torque and axial pressure can be detected respectively by the torque sensor 334 and the pressure sensor 335.

[0065] In this embodiment, the water distributor 336 is a prior art, including a cylindrical shell, in which a hollow shaft is rotatably connected. The surface of the hollow shaft is provided with a water outlet hole connected to its inner cavity. One end of the hollow shaft is connected and sealed with the corresponding end of the tool to be tested 1 through a flange. The shell is connected with a water outlet pipe, which extends into a water tank set in the dynamic test bench body 31.
